Description

Technical Field

[0001] The present invention relates to the technical field of printers, and in particular to a paper receiving device for stacking and collecting single printing media, and a high-speed printer including the paper receiving device. Background Art

[0002] Commercial or industrial high-speed printers, as a single-sheet inkjet printing device, are widely used for large-volume continuous printing of stacked papers (i.e., a structural form in which several sheets of paper are stacked together, such as commercially available copy paper, printing paper, etc.). During such large-volume continuous printing, in order to facilitate subsequent sorting, binding and other finishing operations of the printed papers, when collecting the printed papers, they need to be sorted / copied (hereinafter generally referred to as sorting) and stacked according to the set requirements, that is, in a form of vertical and horizontal dislocation stacking along the height direction at the paper receiving place (dislocation stacking forms a dislocation in the transverse direction of the paper conveying direction). The dislocation distance of the vertical and horizontal dislocation stacking is usually 5-20 mm, such as Figure 16 the laterally misaligned stacked medium C shown. Based on this, the paper receiving place of the aforementioned high-speed printer should be provided with a paper receiving device capable of forming a misaligned stacking of the printed papers.

[0003] In the prior art, there are mainly the following two structural forms for the disclosure of the misaligned stacking paper receiving device.

[0004] The first structural form is that a lateral paper slapping mechanism is arranged above a liftable paper receiving platform. The lateral paper slapping mechanism has a cross bar transverse to the paper conveying direction, a reference side plate is connected to one end of the cross bar, and a paper slapping side plate is connected to the other end of the cross bar.

[0005] The operation process of this technology for misaligned stacking of the papers entering the paper receiving platform is as follows: The reference side plate of the lateral paper slapping mechanism is positioned at a set reference point on the cross bar, and the paper slapping side plate is pulled apart from the reference side plate on the cross bar by a distance sufficient to allow the printed paper to be conveyed in, that is, a collection channel for the printed paper to enter is formed; when it is detected that there is a paper entering the paper receiving platform, the paper slapping side plate of the lateral paper slapping mechanism displaces along the axial direction of the cross bar according to a set stroke, and pushes the current paper flat to abut and align with the reference side plate. This process is repeated in turn, that is, for each paper entering, the paper slapping side plate needs to generate a return stroke from pushing to retracting on the cross bar, so as to form a stacked paper unit of the current set classification (that is, a stack of papers that should be neatly stacked); When entering the paper stacking unit of the next setting category, the reference side plate of the horizontal paper slapping mechanism axially displaces on the cross bar according to the setting and is positioned at the second reference point. The paper slapping side plate forms a channel on the cross bar between it and the reference side plate wide enough for the printed output paper to enter. When it is detected that paper enters the paper receiving platform, the paper slapping side plate of the horizontal paper slapping mechanism axially displaces along the cross bar according to the set stroke, flat-pushes the current paper and abuts and aligns it with the reference side plate, and reciprocates in sequence to form the paper stacking unit of the current set category. In this way, the horizontal paper slapping mechanism reciprocally switches between the first reference point and the second reference point as set, so as to realize the staggered stacking and collection of different groups of paper stacking units in the height direction of the paper receiving platform.

[0006] Obviously, for the technical solution of the above first structural form, the following main technical problems exist: 1. In the process of horizontally aligning each printed output paper by the horizontal paper slapping mechanism, there is an action execution process with a long time-consuming flat-pushing and resetting. During this action execution process, subsequent incoming paper cannot be received. Therefore, this limits the overall paper transmission efficiency of the applied printer and the printer cannot achieve high-efficiency paper conveyance. 2. The latter group of paper stacking units uses the former group of paper stacking units as the stacking bearing surface. Then, during the stacking process of the latter group of paper stacking units on the former group of paper stacking units (especially the initial stacking process of the latter group of paper stacking units), there will be inevitable reciprocating frictional contact between the side plates of the horizontal paper slapping mechanism, especially the paper slapping side plate, on the former group of paper stacking units. This reciprocating frictional contact will cause the stacked paper of the former group of paper stacking units to shift, resulting in poor neatness of the finally stacked and misaligned paper, which is obviously messy. 3. There is no advancing stop structure at the paper head entering the paper receiving platform. Under the conveying inertia of the paper entering the paper receiving platform and the frictional pushing of the subsequent incoming paper, the alignment of the stacked paper on the paper receiving platform in the conveying direction is also significantly poor. Therefore, the paper stacked at the paper receiving platform by the above technology shows serious messiness both in the conveying direction and in the transverse direction of the conveying direction.

[0007] The second structural form, such as the technology disclosed in the Chinese patent document with the title of "A Staggered Paper Receiving Mechanism of a Digital Printer", publication number CN 222757610 U, and publication date April 15, 2025, etc. The specific implementation of this technology is as follows: The liftable paper receiving platform is set as a translatable structure in the conveying transverse direction corresponding to the printed output paper. Above the paper receiving platform, a conveying side baffle plate assembly similar to the above horizontal paper slapping mechanism is arranged. The bottom of the two side plates of the conveying side baffle plate assembly has a bent structure that can support the printed output paper. On the conveying side baffle paperboard assembly, there is a paper side baffle paper assembly connected between the two side plates, which is used to stop and restrain the sequentially entering papers from the paper head; The conveying side baffle paperboard assembly and the paper side baffle paper assembly form a temporary stacking mechanism that can stack the entering papers.

[0008] The process of offset stacking of papers on the paper receiving platform by this technology is as follows: S1. Taking the current batch collection of the temporary stacking mechanism as a group of stacked paper units, and stacking the currently sequentially entering papers neatly according to the set classification by the temporary stacking mechanism; S2. According to the set classification for stacking, when the temporary stacking mechanism completes the current collection, the paper receiving platform displaces horizontally according to the set stroke; S3. The temporary stacking mechanism releases the two side plates of the conveying side baffle paperboard assembly, and stacks the currently collected stacked paper units on the paper receiving platform; S4. Repeat steps S1 to S3, and through different displacements of the paper receiving platform in the horizontal direction, so that the temporary stacking mechanism realizes offset stacking of the stacked paper units collected in different batches in the height direction of the paper receiving platform.

[0009] Obviously, the technical solution of the above second structural form has the following main technical problems: 1. The conveying side baffle paperboard assembly that constitutes the temporary stacking mechanism has a long action execution process when unloading and resetting the stacked paper units collected in each batch. During this action execution process, it cannot receive subsequent incoming papers. Therefore, this limits the overall paper transmission efficiency of the applied printer and cannot enable the printer to achieve high-efficiency paper conveying; 2. The latter group of stacked paper units uses the former group of stacked paper units as the stacking bearing surface. Then, during the stacking process of the latter group of stacked paper units on the former group of stacked paper units, the two side plates of the conveying side baffle paperboard assembly will inevitably have frictional contact with the former group of stacked paper units. This frictional contact will cause the stacked papers of the former group of stacked paper units to shift, resulting in poor neatness of the finally offset-stacked papers; 3. The paper receiving platform realizes offset stacking of each group of stacked paper units by horizontal translation. When the stacked papers on the paper receiving platform are relatively high, the phenomenon of the stacked papers shifting and collapsing is likely to occur during the horizontal translation process, which is not conducive to realizing the stacking and collection of papers with a large height (large batch); 4. The conveying side baffle paperboard assembly that constitutes the temporary storage stacking mechanism has a stacking space that does not gradually decrease as paper continuously enters. To adapt to the stacking of sequentially entering paper, there is a significant height difference between the stacking space of the temporary storage stacking mechanism and the printing output port. The stacking and collection of paper in the front and back order by the temporary storage stacking mechanism are achieved by the sequential dropping of the printed output paper within the stacking space formed by the conveying side baffle paperboard assembly. Moreover, during the temporary storage process, no paper pressing structure intervenes and there is no basis for intervention. This easily causes the dropped paper to be misaligned, warped, or even fall out of the stacking space due to uncontrollable factors such as air resistance and material elasticity, resulting in the failure of stacking and poor neatness of the finally misaligned stacked paper.

[0010] In summary, the existing misaligned stacking paper collection devices generally cannot stack and collect the printing media efficiently output by printers, thus forming a technical restriction on the development of printers with higher transmission efficiency. Moreover, the existing misaligned stacking paper collection devices have poor neatness in stacking and collection. Therefore, the existing misaligned stacking paper collection devices need to be improved. Summary of the Invention

[0011] The technical objective of the present invention is: aiming at the particularity of the misaligned stacking and collection of printed output paper by the above-mentioned high-speed printer and the deficiencies of the existing technology, to provide a single-sheet printing media stacking and collection receiving device that can reliably achieve misaligned stacking and collection of the printing media efficiently output by the printer, with good stacking neatness and stable stacking, as well as a high-speed printer including this receiving device.

[0012] The technical objective of the present invention is achieved through the following technical solutions. A single-sheet printing media stacking and collection receiving device includes a receiving frame and a stop component and a receiving platform arranged on the receiving frame; The receiving frame is arranged at the discharge port of the printer; The stop component is arranged above the receiving platform and is used to stop and restrict each sheet of printed media entering the receiving platform in sequence from the advancing head; The receiving platform is assembled on the receiving frame with a liftable structure and cooperates with the stop component to stack and collect each sheet of printed media entering in sequence; Upstream of the receiving platform, there is an outlet path offset mechanism that is sequentially connected to the printing media conveying path of the printer. The outlet path offset mechanism at least has an oblique conveying mechanism. The oblique conveying mechanism has a guiding edge baffle arranged along the printing media conveying direction, and the driving roller of the oblique conveying mechanism is in an acute angle relationship with the guiding edge baffle in the conveying direction. The printed media entering the oblique conveying mechanism advances along the guiding edge baffle; The discharge path offset mechanism can perform a translational movement on the print medium conveying path in the lateral direction along the print medium conveying direction, so as to change the traveling trajectory of the print medium entering the receiving platform in the lateral direction of the print medium conveying direction; Through the lateral translation transformation of the print medium conveyed by the discharge path offset mechanism, the print media sequentially entering the receiving platform are stacked in a horizontally staggered manner according to the setting.

[0013] Furthermore, the discharge path offset mechanism is arranged on the receiving frame and is located upstream of the receiving platform.

[0014] The above technical measures are aimed at the particularity of the high-speed printer for collecting the printed output media (including but not limited to paper, for example, it may also be a single flat film, etc., in short, any single flat printable carrier is applicable) in a staggered stacking manner. The liftable receiving platform is combined with the upper stop component to align and stack the print media sequentially entering the receiving platform in the conveying direction. On this basis, a discharge path offset mechanism with a specific structure is arranged upstream of the receiving platform. It can be translated laterally along the print medium conveying direction. Through the lateral translation of the discharge path offset mechanism, the continuously conveyed print medium is laterally translated correspondingly in the conveying direction to change the conveying traveling trajectory of the continuously conveyed print medium entering the receiving platform, so as to naturally form a horizontally staggered stacking of the print media sequentially entering the receiving platform according to the set stacking unit (that is, the above-mentioned stacking paper unit, the same below). Specifically, when stacking the same set of stacking units, the laterally translated discharge path offset mechanism keeps the guiding edge stop in a specific position unchanged. Under this state, the print media guided by the edge are sequentially fed into the receiving platform in the conveying direction and are stacked in alignment horizontally; when stacking another set of stacking units, the position of the guiding edge stop is changed through the lateral translation of the discharge path offset mechanism. Under this state, the print media guided by the edge are sequentially fed into the receiving platform in the conveying direction and are stacked in alignment horizontally accordingly; thus, by laterally translating the discharge path offset mechanism, the position of the guiding edge stop is correspondingly changed, so that the print media output through this guiding are stacked and collected in a horizontally staggered manner in the height direction.

[0015] It can be seen that the above technical measures stack the printed media entering the receiving platform horizontally and staggeredly according to the set stacking units. This is achieved by a single horizontal translation of the discharge path offset mechanism with a specific structure to change the conveying path of the continuously conveyed printed media. During the continuous stacking process of the same set of stacking units, there is no redundant stacking action execution process for the printed media entering the receiving platform, which does not affect the continuous reception of subsequent incoming materials. Therefore, it is conducive to reliably and significantly improving the transmission efficiency of the printer for the printed media. When switching to different stacking units, the discharge path offset mechanism only requires a single stroke (in the prior art, processes such as the paper slapping component lifting, the paper receiving platform translating, and the paper slapping component falling are required to achieve this), and it can stack the printed media horizontally and staggeredly, greatly reducing the action time consumption. Therefore, the above technical measures, while achieving the technical effect of horizontally and staggeredly stacking the printed media, can reliably receive the printed media output by the printer with high efficiency, which is conducive to improving the overall paper transmission efficiency of the applied printer and provides effective technical support for developing printers with higher transmission efficiency. At the same time, the above technical measures achieve horizontal and staggered stacking by changing the different conveying paths of the printed media entering the receiving platform, without redundant stacking, collecting, frictional contact, and force application. Thus, it can ensure that the printed media constituting the stacking unit are neatly aligned during natural stacking, and the horizontally and staggeredly stacked groups of stacking units are neatly stacked in the height direction, thereby reliably ensuring the neatness of the final staggered stacking and making the stacking neatness good. Also, because the horizontal and staggered stacking of the printed media on the receiving platform is achieved by changing its own conveying path, the receiving platform only makes a downward movement to adapt to the change in stacking height, and there is no other structure generating extrusion force on the side of the stacking structure of the printed media. In this way, it can ensure that the printed media form a stable stack on the receiving platform, which is conducive to achieving stacking and collection at a relatively large height (relatively large batch).

[0016] In the above technical measures, the discharge path offset mechanism can be arranged on the receiving frame and be upstream of the receiving platform, or it can be arranged on the main frame of the printer body and be upstream of the receiving platform. When the discharge path offset mechanism is arranged on the receiving frame, the "corresponding frame" mentioned refers to the receiving frame; when the discharge path offset mechanism is arranged on the main frame of the printer body, the "corresponding frame" mentioned refers to the main frame of the printer body.

[0017] As one of the preferred technical solutions, the diagonal conveying mechanism of the discharge path offset mechanism is a diagonal roller conveying mechanism; The inclined roller conveying mechanism comprises a plurality of transmission inclined rollers which are sequentially mounted on corresponding frames along the conveying direction of the printing medium and can rotate, a guide side block arranged along the conveying direction of the printing medium at one end of the transmission inclined rollers and guiding the conveyed printing medium, a sliding drive component which drives the guide side block to perform translational movement on the corresponding frame in the transverse direction of the conveying direction of the printing medium, and a rotation drive component which drives the transmission inclined rollers to rotate along the set conveying direction; Each transmission slanted roller cooperates with the guide edge block at an acute angle in the direction of printing medium conveyance, and each transmission slanted roller rotates along the set conveyance direction to drive the incoming printing medium to approach the guide edge block, and convey the incoming printing medium to the receiving platform with the guide edge block as the alignment reference; The guide edge block is assembled on the corresponding frame in a translationally movable structure through the sliding drive assembly.

[0018] The above technical measures form a discharge path deviation mechanism with an inclined roller conveying mechanism that can change the conveying trajectory. Based on the side conveying characteristics of the inclined roller conveying mechanism, the printing medium conveyed sideways is guided during the conveying process by the guide side block, that is, the travel trajectory of the printing medium in continuous conveying is guided to ensure that each printing medium constituting the same group of stacking units on the receiving platform enters the receiving platform along the same travel trajectory, thereby ensuring that each printing medium entering the receiving platform along the same travel trajectory naturally forms a highly uniform stacking. Based on this, the travel trajectory of the continuously conveyed printing medium is changed by the guide side block, so that the stacking units of different batches in the continuous conveying form a highly uniform horizontal offset stacking in the height direction of the receiving platform.

[0019] Furthermore, the oblique roller conveying mechanism has a bridge plate arranged on the periphery of the transmission oblique roller and cooperating with the transmission oblique roller to carry the conveyed printing medium; The bottom of the guide side block has a side block transition bottom edge with a bent structure, and the side block transition bottom edge is overlapped and matched with the edge bottom of the bridge plate on the side of the guide side block; When the guide edge block performs translational movement in the transverse direction of the printing medium conveying direction, the transition bottom edge of the edge block cooperates with the corresponding edge of the bridge plate in an overlapping relationship.

[0020] The above-mentioned technical measures are based on the characteristics of the side-conveying of the inclined roller conveying mechanism and the special structure of the guide side guard which moves laterally with reference to the transmission inclined roller. Without interfering with the rotational movement of the transmission inclined roller, it can effectively prevent the printing medium conveyed sideways from getting stuck in the combining gap of the lateral translation of the guide side guard, thereby reliably meeting the technical requirements of the lateral translation of the guide side guard for changing the travel trajectory of the printing medium.

[0021] Further, between the guiding edge stopper and the corresponding frame, at least one set of linear sliding components corresponding to the translation direction of the guiding edge stopper is provided; Driven by the sliding drive assembly, the guiding edge stopper performs a translation movement on the corresponding frame along the linear sliding components.

[0022] The above technical measures can ensure that the guiding edge stopper that translates horizontally performs a stable lateral displacement with reference to the driving inclined rollers on the corresponding frame (such as the receiving frame), with high precision and good stability.

[0023] As an alternative technical solution, the oblique conveying mechanism of the discharge path offset mechanism is an inclined roller conveying mechanism; The inclined roller conveying mechanism has an inclined roller bracket assembled on the corresponding frame with a horizontal translation structure, multiple driving inclined rollers that are sequentially assembled on the inclined roller bracket along the printing medium conveying direction and can rotate, a guiding edge stopper arranged at one end of these driving inclined rollers along the printing medium conveying direction to guide the conveyed printing medium, a sliding drive assembly that drives the inclined roller bracket to perform a horizontal translation movement along the printing medium conveying direction on the corresponding frame, and a rotation drive assembly that drives these driving inclined rollers to rotate along the set conveying direction; In the printing medium conveying direction, each driving inclined roller cooperates with the guiding edge stopper at an acute angle. The driving inclined rollers that rotate along the set conveying direction drive the incoming printing medium to lean against the guiding edge stopper and move forward to the receiving platform with the guiding edge stopper as the alignment reference; The guiding edge stopper is fixedly assembled on the inclined roller bracket.

[0024] The above technical measures form the discharge path offset mechanism with an inclined roller conveying mechanism whose conveying trajectory can be changed. Based on the characteristic of the inclined roller conveying mechanism of conveying along the edge, the guiding edge stopper guides the printing medium conveyed along the edge during the conveying process, that is, guides the traveling trajectory of the continuously conveyed printing medium, so as to ensure that the printing media forming the same set of stacking units enter the receiving platform along the same traveling trajectory, and further ensure that the printing media entering the receiving platform along the same traveling trajectory naturally form a highly neat stack. Based on this, by changing the traveling trajectory of the continuously conveyed printing medium through the guiding edge stopper, different batches of stacking units during continuous conveying form a highly neat horizontal staggered stacking in the height direction of the receiving platform.

[0025] As one of the preferred technical solutions, the receiving device further includes a translation automatic control system for controlling the horizontal translation movement of the corresponding structure of the discharge path offset mechanism. The translation automatic control system mainly consists of a counting sensor, a sliding stroke sensor, a motor constituting the sliding drive assembly, and a controller; The counting sensor is used to detect the number of printing media sequentially entering the receiving platform and feedback a detection signal to the controller according to a set counting period; The sliding stroke sensor is used to detect the horizontal translation movement stroke position of the corresponding structure of the discharge path offset mechanism driven by the sliding drive assembly and feedback a detection signal to the controller; The motor constituting the sliding drive assembly, under the control instruction of the controller, is used to drive the sliding drive assembly to act according to a set movement direction and stroke, so as to drive the corresponding structure of the discharge path offset mechanism to perform horizontal translation reciprocating movement.

[0026] The above technical measures are designed to meet the automatic control of horizontal staggered stacking, and can enable the printing media continuously output by the printer to automatically form stacking units according to the designed number of sheets, and on this basis form horizontal staggered stacking, with high automation and accuracy.

[0027] Further, the counting sensor is arranged at the output end of the discharge path offset mechanism; When the printing media output by the discharge path offset mechanism enters the receiving platform, it passes through the detection range of the counting sensor.

[0028] Using the counting sensor of the above technical measures to trigger the instruction output action of the controller is easy to implement and has a low technical difficulty while meeting high precision.

[0029] As one of the preferred technical solutions, the discharge path offset mechanism further has a wind mechanism; The wind mechanism can generate wind on the conveying working surface of the oblique conveying mechanism, and the direct action area of the wind generated by the wind mechanism on the conveying working surface of the oblique conveying mechanism is close to the guiding edge baffle; When the printing media is conveyed to the oblique conveying mechanism, the wind generated by the wind mechanism acts on the currently conveyed printing media, forcing the currently conveyed printing media to move forward to the receiving platform with the guiding edge baffle as the alignment reference on the oblique conveying mechanism.

[0030] The above technical measures form a discharge path offset mechanism by combining a wind power mechanism arranged at a specific position with an inclined conveyor mechanism, which can increase the lateral frictional force of the printing medium entering the inclined conveyor mechanism in contact with the inclined conveyor mechanism at the guiding edge stop, forcing the printing medium during the continuous conveying process of the inclined conveyor mechanism to accelerate towards the edge with the guiding edge stop as the alignment reference, so as to improve the accuracy of the printing medium output by the inclined conveyor mechanism to align with the edge, and further facilitate improving the neatness of the printing medium stacked on the receiving platform. At the same time, forcing the printing medium to be conveyed along the edge on the inclined conveyor mechanism by the wind power mechanism will not interfere with or consume time for the mechanical actions of the conveyed printing medium. That is to say, this way of accelerating towards the edge does not affect the high-efficiency conveying of the printing medium and meets the technical requirements for the high-efficiency conveying of the printing medium.

[0031] Furthermore, the direct acting area of the wind force generated by the wind power mechanism on the conveying working surface of the inclined conveyor mechanism is within the range of two-thirds of the transverse width of the currently conveyed printing medium with the guiding edge stop as the conveying reference.

[0032] Still further, the printing medium is a single and flat one of the printing medium specifications of A3, A4, B3, B4, 8K, 16K; The direct acting area of the wind force generated by the wind power mechanism on the conveying working surface of the inclined conveyor mechanism is within the range of 200 mm in transverse width with the guiding edge stop as the conveying reference and wider than the conveying direction.

[0033] Still further, the printing medium is printing paper; The wind pressure of the wind force generated by the wind power mechanism directly acting on the currently conveyed printing medium is within the range of 2 - 50 Pa.

[0034] The above technical measures enable the wind power mechanism to reliably cooperate with the inclined conveyor mechanism to reliably accelerate the printing medium towards the edge during dynamic conveying, so as to ensure that the printing medium on the inclined conveyor mechanism uses the guiding edge stop as its alignment reference. At the same time, the above technical measures can avoid the printing medium from generating impact floating offset, concave bending deformation, etc. on the inclined conveyor mechanism due to excessive wind force, and have good conveying stability during the process of meeting the acceleration towards the edge.

[0035] Furthermore, the air outlets of the wind power mechanism are arranged above the conveying working surface of the inclined conveyor mechanism, and the wind passing through the air outlets acts on the conveying working surface of the inclined conveyor mechanism in a blowing manner, and the direct conveying path of the wind passing through the air outlets, with the guiding edge stop as the reference, is in a right-angle or obtuse-angle relationship with the acting plane of the currently conveyed printing medium; Alternatively, the diagonal conveying mechanism is a diagonal roller conveying mechanism, and the air outlets of the air force mechanism are arranged below the conveying working surface of the diagonal roller conveying mechanism. The air force passing through the air outlets acts on the conveying working surface of the diagonal roller conveying mechanism in a suction manner, and the direct conveying path of the air force passing through the air outlets, with the guiding edge baffle as the reference benchmark, is in a right-angle or acute-angle relationship with the acting plane of the currently conveyed printing medium.

[0036] In the above technical measures, if the direct conveying path of the blown air force of the air force mechanism is basically parallel to the guiding edge baffle, thereby increasing the contact friction force between the printing medium and the diagonal conveying mechanism to ensure that the printing medium accelerates towards the edge during the conveying process. If the direct conveying path of the blown air force of the air force mechanism forms an obtuse-angle mating relationship (for the air outlet above) / acute-angle mating relationship (for the air outlet below) with the acting plane of the printing medium on the side facing the guiding edge baffle, it can not only increase the contact friction force between the printing medium and the diagonal conveying mechanism, but also apply a certain thrust / suction force towards the guiding edge baffle to the printing medium, cooperating with the dynamic conveying process of the diagonal conveying mechanism for the printing medium to accelerate towards the edge more efficiently.

[0037] Furthermore, the air force mechanism has a fan bracket and multiple small electric fans arranged on the fan bracket; The fan bracket is fixed on the corresponding frame where the diagonal conveying mechanism is located; Each small electric fan is arranged in sequence on the fan bracket along the conveying direction of the printing medium.

[0038] The air force mechanism composed of the above technical measures has, on the one hand, technical characteristics such as simple structure, easy to form, low manufacturing cost and low later maintenance cost, and convenient for later maintenance; on the other hand, it can effectively fit the conveying range of the diagonal roller conveying mechanism, so that the printing medium accelerates towards the edge with the guiding edge baffle as the alignment benchmark during the continuous conveying process of the diagonal roller conveying mechanism.

[0039] As one of the preferred technical solutions, above the receiving platform and / or the discharge path offset mechanism, a pressing transmission mechanism that drives along the conveying direction of the printing medium is arranged; The pressing transmission mechanism has a front shaft that first cooperates with the currently conveyed printing medium, a rear shaft that later cooperates with the currently conveyed printing medium, and multiple medium guiding belts that are sleeved between the front shaft and the rear shaft and are circularly driven. These medium guiding belts are arranged at intervals along the axial directions of the front shaft and the rear shaft; During the circular driving process of the medium guiding belts, in cooperation with the receiving platform and / or the discharge path offset mechanism below, a channel that allows the currently conveyed printing medium to enter and prevents drift is formed.

[0040] The blanking transmission mechanism of the above technical measures, in cooperation with the material receiving platform below and / or the discharging path offset mechanism, forms a conveying channel for the printing medium, thereby ensuring the stability of the printing medium below to prevent drifting, which is beneficial to improving the final stacking neatness.

[0041] As one of the preferred technical solutions, the stop assembly has a baffle cross beam assembled on the material receiving frame and located above the material receiving platform, and the baffle cross beam is arranged on the material receiving frame in a structure transverse to the conveying direction of the printing medium; A plurality of downwardly protruding baffle protrusions are arranged at intervals at the bottom of the baffle cross beam. The downward protruding height of these baffle protrusions can at least cover the discharge port of the discharging path offset mechanism in the positive projection in the horizontal direction. The surfaces of these baffle protrusions facing the printing medium are of a coplanar structure, and the arrangement distance between adjacent baffle protrusions is less than the transverse width dimension of the printing medium in the conveying direction. The printing medium entering the material receiving platform covers at least two baffle protrusions in the transverse width direction in the conveying direction; When the material receiving platform rises to the highest position on the material receiving frame, an upper and lower staggered fit is formed between the bearing plane of the material receiving platform and the lowest end of the baffle protrusion. The surface of the baffle protrusion facing the printing medium constitutes a space for stacking each sheet of printing medium entering in sequence above the bearing plane of the material receiving platform.

[0042] The above technical measures use a plurality of baffle protrusions at the bottom of the cross beam to perform multi-point contact stop on the printing medium entering the material receiving platform in the transverse direction, thereby ensuring that the printing medium entering the material receiving platform is smoothly stressed at the advancing head to prevent the printing medium from being impacted and tilted and displaced in the advancing direction, which is beneficial to improving the final stacking neatness.

[0043] Further, the baffle cross beam is assembled on the material receiving frame in a slidable structure corresponding to the conveying direction of the printing medium; Correspondingly, at the bearing plane of the material receiving platform, a plurality of relief grooves are provided along the conveying direction of the printing medium and matching the respective baffle protrusions on the baffle cross beam for passing through.

[0044] The above technical measures form relief grooves on the material receiving platform for the baffle protrusions on the cross beam to pass through, and cooperate with the slidable structure of the cross beam, so that the stop assembly can cooperate with the material receiving platform to form a material receiving space adapted to different specifications, with good flexibility. Moreover, the relief groove structure on the material receiving platform will not interfere with the material receiving platform's bearing of the printing medium stack, and can ensure the stable stacking of the printing medium on the material receiving platform. At the same time, the relief groove structure on the material receiving platform is beneficial to reliably fork and unload the material receiving platform after stacking is completed, and the unloading operation is highly convenient.

[0045] Further, the material baffle cross beam is assembled on the material receiving rack in a slidable structure through sliders; A pressure roller is connected to the slider and is located on the front side of the material baffle cross beam to prevent the printing medium entering the material receiving platform from drifting.

[0046] Regarding the slidability of the cross beam, the above technical measures form a pressure roller following the cross beam on the sliding structure of the cross beam. Thus, no matter how the cross beam slides, it can ensure that the pressure roller suppresses the printing medium stacked below to prevent drifting. Especially in cooperation with the pressure transmission mechanism, it can suppress while not affecting the feeding, which is beneficial to improving the stacking stability of the printing medium on the material receiving platform and also beneficial to improving the stacking neatness of the printing medium on the material receiving platform.

[0047] Further, the material receiving platform extends out of the material receiving rack corresponding to the conveying direction of the printing medium; Correspondingly, the stop assembly further has a material baffle support for assembling the material baffle cross beam. The material baffle support is fixed on the material receiving rack and is located above the material receiving platform. The material baffle support is at least a cantilever structure extending along the conveying direction of the printing medium; The material baffle cross beam is assembled on the cantilever of the material baffle support in a slidable structure.

[0048] The above technical measure that the material receiving platform extends out of the material receiving rack makes the operation space on the material receiving platform open while not hindering the stable stacking and receiving of materials, which is beneficial to the unloading operation.

[0049] As one of the preferred technical solutions, the material receiving device further includes a lifting automatic control system for controlling the lifting movement of the material receiving platform. The lifting automatic control system mainly consists of a material receiving detection sensor, a lifting stroke sensor, a motor constituting the lifting drive assembly, and a controller; The material receiving detection sensors are arranged above the material receiving platform and form an input channel for sequentially conveying the printing medium between the bearing plane of the material receiving platform and the uppermost printing medium during the continuous stacking process. The material receiving detection sensors are used to detect the stacking height of the printing medium continuously stacked on the material receiving platform and feedback the detection signal to the controller; The lifting stroke sensor is used to detect the vertical lifting movement stroke position of the material receiving platform driven by the lifting drive assembly and feedback the detection signal to the controller; The motor constituting the lifting drive assembly, under the control command of the controller, is used to drive the lifting drive assembly to act according to the set movement direction and stroke, so as to drive the material receiving platform to perform vertical reciprocating lifting movement on the material receiving rack.

[0050] The above technical measures are designed to meet the automated control of printing media stacking collection, and can enable the collecting platform to descend smoothly with the dynamic change of the continuous stacking height of the printing media, so as to ensure the smoothness of the feeding and the neatness and stability of the stacking, with high automation and precision.

[0051] A high-speed printer comprises a printer body, wherein the printer body has a sequential conveying path for a single printing medium from supply to collection; A material receiving device of any of the above structures is arranged at the material outlet of the sequential conveying path of the printer body to stack and collect the printing media output by the printer body in a set stacking manner.

[0052] The high-speed printer with the above technical measures has a material receiving device with the above structure arranged at the material outlet, and thus has the technical advantages of the above material receiving device.

[0053] The beneficial technical effect of the present invention is as follows: the above technical measures are aimed at the particularity of the above high-speed printer collecting the print output media in staggered stacking. On the basis of the liftable material receiving platform cooperating with the upper stopper assembly, a material discharge path offset mechanism of a specific structure is arranged upstream of the material receiving platform, which can be translated laterally along the conveying direction of the print medium. Through the lateral translation of the material discharge path offset mechanism, the continuously conveyed print medium is correspondingly translated laterally in the conveying direction, so as to change the conveying trajectory of the continuously conveyed print medium entering the material receiving platform, so as to naturally form a horizontal staggered stacking for each print medium that sequentially enters the material receiving platform according to the set stacking unit. Since the above technical measures do not have redundant stacking action execution processes for the print media entering the material receiving platform, while realizing the technical effect of horizontal staggered stacking for the print media, the print media efficiently output by the printer can be reliably received, which is conducive to improving the overall paper transmission efficiency of the applied printer, and provides effective technical support for the development of printers with higher transmission efficiency.

[0054] At the same time, the above technical measures can ensure that the printing media constituting the stacking unit form high-quality alignment in natural stacking, and each group of stacking units with laterally staggered stacking are stacked regularly in the height direction, thereby reliably ensuring the neatness of the final staggered stacking; it can ensure that the printing media forms a stable stack on the material receiving platform, which is conducive to the realization of stacking collection with a larger height (larger batches).

[0073] The present invention relates to the technical field of printers, and specifically relates to a receiving device for single - sheet printing medium stacking and collection, and a high - speed printer including the receiving device. The main technical solution content of the present invention will be specifically described below in combination with multiple embodiments. Among them, Embodiment 1 combines the specification drawings - that is Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 , Figure 17 and Figure 18 clearly and detailedly explain the technical solution content of the present invention. Although other embodiments are not separately drawn with drawings, their main structures can still refer to the drawings of Embodiment 1.

[0074] It should be specifically noted here that: 1. The drawings of the present invention are schematic. In order to clarify the technical purpose of the present invention, unnecessary details have been simplified to avoid obscuring the technical solutions contributed by the present invention to the prior art. 2. The printing medium of the present invention is usually a single flat sheet of paper, but printable media such as single flat sheets of film are not excluded, that is, any single flat printable medium is applicable; as for folded paper, thick plate media, etc., they are not applicable to the present invention, that is, the printing medium of the present invention does not include these. 3. Expressions such as "about" and "substantially" regarding quantity or mating relationship in the following text mean that reasonable assembly errors, processing errors, etc. in the industry are allowed to exist, rather than absolute quantity or mating relationship in literal expression.

[0075] Embodiment 1 The high-speed printer of the present invention is as Figure 17 and Figure 18 shown. The high-speed printer is a commercial or industrial high-speed continuous printer (i.e., a single-sheet inkjet printer, only for the printing medium in the stacking mode, rather than the printing medium in the roll mode), and it has a printer body 9. The printer body 9 has a main frame 91 and a feeding mechanism 92 (paper feeding mechanism) and a receiving mechanism (paper receiving mechanism) arranged on the main frame 91 - that is, the receiving device of the present invention.

[0076] Taking the length direction of the main frame 91 of the printer body 9 as a reference, the feeding mechanism 92 and the receiving device of the present invention are separately arranged at the left and right ends of the main frame 91. Between the feeding mechanism 92 and the receiving device of the present invention, a sequential conveying path for single-sheet printing media in the stacked printing media from supply (feeding) to collection is formed on the main frame 91.

[0077] Among them, the feeding mechanism 92 is arranged at the feeding port of the sequential conveying path of the main frame 91. The feeding mechanism 92 is used for placing stacked printing media (such as stacked paper) and separating and conveying them one by one. In this embodiment, in order to achieve continuous conveying of a large number of printing media, reduce interruption and shutdown due to lack of printing media during printing, the feeding mechanism 92 is redundantly configured in two groups. These two groups of feeding mechanisms share the same feeding support and are arranged in a high-low layer on the common feeding support.

[0078] Specifically, Feeding Mechanism 1 is below Feeding Mechanism 2, and it is sequentially connected to the upstream end of the sequential conveying path through a feeding conveying section.

[0079] At the feeding port of the second feeding mechanism, there is arranged a feeding bypass conveying mechanism that sequentially connects the feeding port of the second feeding mechanism with the feeding conveying section. That is, the feeding port of the second feeding mechanism is connected to the connection point between the feeding port of the first feeding mechanism and the feeding conveying section through the feeding bypass conveying mechanism, so that the printing medium conveyed by the second feeding mechanism enters the first flat conveying section that constitutes the sequential conveying path through the feeding bypass conveying mechanism and the feeding conveying section. The feeding bypass conveying mechanism is basically arranged vertically on the feeding support.

[0080] Based on the above redundant configuration of the first feeding mechanism and the second feeding mechanism, during the printing operation, simultaneous feeding cannot be formed, only single feeding is possible. Therefore, the feeding rollers at the feeding ports of the first feeding mechanism and the second feeding mechanism only start to rotate when feeding currently, otherwise they are in a stationary state. Their rotation actions are controlled by the control system of the printer, that is, the control system controls the switching of the first feeding mechanism and the second feeding mechanism for feeding with a set command. Thus, assuming that the first feeding mechanism feeds first and the second feeding mechanism is in standby for feeding, when the stack of printing media placed on the first feeding mechanism is continuously consumed during feeding, the control system switches the second feeding mechanism to continue feeding, so that the operator can freely place the stack of printing media on the first feeding mechanism without interfering with the continuous operation of the printer, making the first feeding mechanism in standby for feeding. The same applies when the second feeding mechanism is continuously consumed during feeding.

[0081] The receiving device of the present invention is arranged at the discharge port of the sequential conveying path of the main frame 91, and is used to receive the printing media output by the sequential conveying path and stack and collect each received printing media according to the set requirements.

[0082] Between the above-mentioned feeding mechanism 92 and the receiving device of the present invention, the sequential conveying path of the single printing medium in the stack of printing media from supply (feeding) to collection on the main frame 91 has, in the height direction of the main frame 91, a first flat conveying section, a first vertical conveying section, a second flat conveying section, a second vertical conveying section, and a third flat conveying section that are sequentially connected. Among them, the third flat conveying section is arranged above the second flat conveying section. The third flat conveying section serves as a transition conveying section between the sequential conveying path and the receiving device of the present invention, and there is not too much requirement for its horizontal state, and basic horizontal conveying can be achieved. The tail end of the third flat conveying section is sequentially connected to the receiving device of the present invention.

[0083] The second flat conveying section is arranged above the first flat conveying section. As described below, the second flat conveying section needs to arrange a printing mechanism and a deviation correction mechanism, so the second flat conveying section is basically horizontally arranged on the main frame 91.

[0084] The head end of the first horizontal conveying section is sequentially connected to the feeding mechanism. As described below, the first horizontal conveying section needs to arrange a printing mechanism and a deviation rectifying mechanism, so the first horizontal conveying section is basically horizontally arranged on the main frame 91.

[0085] In this way, between the feeding mechanism 92 on the main frame 91 and the material receiving device of the present invention, a sequential conveying path of an S-shaped winding structure from bottom to top is formed, so that while meeting the technical requirements for setting the sequential conveying path for double-sided printing, the length dimension of the main frame 91 can be effectively reduced, thereby reducing the floor area.

[0086] Based on the structural characteristics of the above-mentioned feeding mechanism 92 and the sequential conveying path characteristics of the S-shaped winding structure from bottom to top on the main frame 91, in order to facilitate the arrangement of the first feeding mechanism on the main frame 91 and its smooth connection with the head end of the first horizontal conveying section, the feeding conveying section arranged at the feeding port of the first feeding mechanism is arranged on the feeding support in an inclined structure.

[0087] Since the structural volume of the high-speed printer of the present invention is relatively large compared to that of a general office printer, in order to facilitate the transportation of the whole machine and reduce the high requirements for the transportation space, the feeding support of the above-mentioned feeding mechanism 92 is assembled at the corresponding end of the main frame 91 in a detachable combined structure. Similarly, the receiving frame of the above-mentioned material receiving device of the present invention is assembled at the corresponding end of the main frame 91 in a detachable combined structure.

[0088] To adapt to double-sided printing of the conveyed printing medium, a first printing mechanism is arranged on the above-mentioned first horizontal conveying section, and a second printing mechanism is arranged on the above-mentioned second horizontal conveying section; the first printing mechanism and the second printing mechanism respectively adopt an inkjet printing structure. The working process of its printing operation is as follows according to the setting in the control system for the printing task: When only single-sided printing is required for the current printing medium, the printing medium conveyed by the feeding mechanism 92 will be conveyed along the first horizontal conveying section, the first vertical conveying section, the second horizontal conveying section, the second vertical conveying section and the third horizontal conveying section in an S-shaped path; during the conveying process, according to the set instruction, the corresponding printing mechanism on the first horizontal conveying section / second horizontal conveying section prints graphic and text information on the upper surface of the conveyed printing medium, and the other printing mechanism does not work, and the conveying section where it is located only conveys the current printing medium. When double-sided printing is required for the current printing medium, the printing medium conveyed by the feeding mechanism 92 is on the first horizontal conveying section. The first printing mechanism prints on the upward-facing surface. After that, through the conveyance of the first vertical conveying section, the printing medium that has completed the first-sided printing forms with the second side facing up and the printed first side facing down on the second horizontal conveying section. After the second printing mechanism prints on the second side, double-sided printing is completed, and then it is conveyed to the receiving device of the present invention through the second vertical conveying section and the third horizontal conveying section.

[0089] To ensure high-quality printing with a consistent positioning reference for the front and rear printing media sequentially conveyed by the above-mentioned first printing mechanism and second printing mechanism, corresponding to the set conveying direction of the printing medium on the sequential conveying path, at the upstream of the first printing mechanism, a first deviation correction mechanism for correcting the deviation of the single-piece printing medium conveyed is provided, that is, the first deviation correction mechanism and the first printing mechanism are both on the first horizontal conveying section; at the upstream of the second printing mechanism, a second deviation correction mechanism for correcting the deviation of the single-piece printing medium conveyed is provided, that is, the second deviation correction mechanism and the second printing mechanism are both on the second horizontal conveying section.

[0090] The structures of the above-mentioned first rectifying mechanism and the second rectifying mechanism are the same. In this embodiment, the rectifying mechanism includes an obliquely conveying mechanism and a wind force mechanism that cooperate with each other. Specifically, the obliquely conveying mechanism is an inclined roller drive structure, which has a plurality of driving inclined rollers that are sequentially assembled on the main frame 91 along the conveying direction of the printing medium and can rotate. These driving inclined rollers are assembled on the same plane on the main frame 91 in a rotatable structure, and the same fitting clearance and inclination angle are basically maintained between adjacent driving inclined rollers. The obliquely conveying mechanism also has a guiding edge stop that is convexly formed on one side of the obliquely conveying mechanism along the conveying direction of the printing medium. The guiding edge stop is fixedly connected to the main frame 91, and it is stationary compared with the driving inclined rollers. Moreover, the guiding edge stop aligns with the positioning reference of the downstream printing mechanism that cooperates with it. Each driving inclined roller cooperates with the guiding edge stop at an acute angle in the conveying direction of the printing medium. The wind force mechanism has a fan bracket and a plurality of groups of electric fans arranged on the fan bracket. The fan bracket is supported and fixed on the main frame 91 and is located above the obliquely conveying mechanism. Each group of electric fans is arranged on the fan bracket along the conveying direction of the printing medium, and the arrangement positions of these electric fans basically correspond to the longitudinal length of the conveying working surface of the obliquely conveying mechanism. The air outlet of the wind force mechanism faces the conveying working surface of the obliquely conveying mechanism, and the direct conveying path of the wind force blown by the wind force mechanism, with the guiding edge stop as the reference benchmark, cooperates with the acting plane of the obliquely conveying mechanism at a right angle relationship. That is to say, the direct conveying path of the wind force blown by the wind force mechanism is basically parallel to the guiding surface of the guiding edge stop. In the cooperation relationship between the wind force mechanism and the obliquely conveying mechanism, the wind force blown by the wind force mechanism cannot cover the lateral width of the currently conveyed printing medium in the lateral direction (with the conveying direction of the printing medium as the longitudinal direction) of the obliquely conveying mechanism, and can only act on the area of the currently conveyed printing medium close to the guiding edge stop. That is, the direct acting area of the wind force blown by the wind force mechanism in the conveying working surface of the obliquely conveying mechanism should be close to the guiding edge stop, so as to cooperate with the obliquely conveying mechanism to dynamically turn and rectify the conveyed printing medium during conveying. Usually, the wind pressure of the wind force blown by each electric fan of the wind force mechanism directly acting on the currently conveyed printing medium should be controlled within the range of 2 to 50 Pa, preferably within the range of 5 to 10 Pa.

[0091] As described above, on the main frame 91 between the feeding mechanism 92 and the receiving device of the present invention, an upward sequential conveying path is formed that is sequentially connected by a feeding conveying section, a first horizontal conveying section, a first vertical conveying section, a second horizontal conveying section, a second vertical conveying section, and a third horizontal conveying section, and it is necessary to convey the printing medium output by the feeding mechanism 92. Therefore, conveying mechanisms for conveying the printing medium in a set direction must be arranged on each conveying section. There are no specific structural requirements for these conveying mechanisms, and common paper conveying mechanisms currently available can be used as long as they can meet the conveying of the printing medium (such as paper).

[0092] As described above, the material receiving device of the present invention is arranged at the discharge port of the sequential conveying path of the main frame 91 of the printer body 9, and is used to receive the printing medium output by the sequential conveying path and stack and collect each received printing medium according to the set requirements.

[0093] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 and Figure 16 As shown in

[0094] , the material receiving device of the present invention includes a material receiving frame 1 and a stop component 2, a material receiving platform 3, a material receiving detection sensor 4, a first pressing and driving mechanism 5, a discharge path offset mechanism 6, a counting sensor 7, a second pressing and driving mechanism 8 and a corresponding automatic control system arranged on the material receiving frame 1.

[0095] Specifically, the material receiving frame 1 is assembled at the discharge port of the main frame 91 of the printer body 9 in a detachable structure and is used to receive the printing medium output by the sequential conveying path in the main frame 91.

[0095] As Figure 15 and Figure 16 shown, the material receiving platform 3 serves as a carrier for receiving the printing medium and stacking the received printing medium. To enable the printing medium to smoothly enter the material receiving platform 3 and adapt to the batch collection and stacking of the printing medium continuously output by the printer body 9, the material receiving platform 3 is assembled on the material receiving frame 1 in a liftable structure.

[0096] More specifically, the material receiving platform 3 is assembled on the material receiving frame 1 in a vertical linear sliding structure, and the material receiving platform 3 is connected with a lifting drive assembly for controlling the linear sliding action. The lifting drive assembly is a lead screw transmission pair structure, mainly composed of a transmission lead screw, a drive motor and a nut; the lifting drive assembly also has a material receiving automatic control system, and the material receiving automatic control system controls the lifting movement of the material receiving platform 3 by driving the lead screw transmission pair.

[0097] The transmission lead screw of the lifting drive assembly is vertically assembled on the material receiving frame 1 in a rotatable structure, and the bottom end of the transmission lead screw is connected to the drive motor. The nut of the lifting drive assembly is fixedly connected to the material receiving platform 3 and is threadedly connected to the transmission lead screw. During the rotation of the transmission lead screw, by driving the nut and the linear sliding assembly of the material receiving platform 3 on the material receiving frame 1, the material receiving platform 3 is driven to perform a linear displacement lift on the material receiving frame 1.

[0098] The automatic material receiving control system mainly consists of a material receiving detection sensor 4, a lifting stroke sensor, the drive motor that constitutes the lifting drive assembly, and a controller. Among them, the material receiving detection sensor 4 is arranged above the material receiving platform 3, and an input channel for sequentially conveying the printing medium is formed between the bearing plane 31 of the material receiving platform 3 and the uppermost printing medium during the continuous stacking process. The material receiving detection sensor 4 is used to detect the stacking height of the printing medium continuously stacked on the material receiving platform 3 and feedback the detection signal to the controller. The lifting stroke sensor is used to detect the vertical lifting movement stroke position of the material receiving platform 3 driven by the lifting drive assembly and feedback the detection signal to the controller. The drive motor that constitutes the lifting drive assembly, under the control command of the controller, is used to drive the lifting drive assembly to act according to the set movement direction and stroke, so as to drive the material receiving platform 3 to perform a vertical lifting reciprocating movement on the material receiving frame 1.

[0099] To improve the convenience of unloading the stacked printing medium on the material receiving platform 3, the above-mentioned material receiving platform 3 extends out of the material receiving frame 1 corresponding to the printing medium conveying direction, as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 15 、 Figure 17 and Figure 18 shown. That is to say, a part of the material receiving platform 3 close to the printer body 9 is within the space restricted by the material receiving frame 1, and a part of the material receiving platform 3 far from the printer body 9 extends out of the space restricted by the material receiving frame 1, so that the stacking collection space formed by the material receiving platform 3 is relatively open, facilitating the unloading operation of the stacked media collected.

[0100] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 7 、 Figure 13 、 Figure 14 、 Figure 15 、 Figure 17 and Figure 18As shown, the stop assembly 2 is arranged above the material receiving platform 3 and is used to stop and constrain each sheet of printing medium that sequentially enters the material receiving platform 3 from the traveling head (the paper head, the same below). On the one hand, it prevents the printing medium from running out due to conveying inertia after entering the material receiving platform 3. On the other hand, through the stop constraint, each sheet of printing medium is benchmark-aligned in the traveling direction (the conveying direction, the same below) to improve the neatness of stacking. The stop assembly 2 mainly consists of a material blocking bracket 21 and a material blocking cross beam 22.

[0101] More specifically, as Figure 3 , Figure 7 , Figure 13 and Figure 14 shown, there are two material blocking brackets 21 of the stop assembly 2, which are arranged at intervals corresponding to the transverse direction of the material receiving frame 1 and are respectively fixed on the material receiving frame 1, located above the material receiving platform 3, forming a cantilever arrangement structure on the material receiving frame 1, that is, each material blocking bracket 21 is a cantilever structure extending along the conveying direction of the printing medium. The two ends of the material blocking cross beam 22 of the stop assembly 2 are connected to the corresponding material blocking brackets 21 on both sides, relatively located at a position far from the printer body 9, and also located above the material receiving platform 3. The material blocking cross beam 22 is arranged on the material receiving frame 1 in a structure transverse to the conveying direction of the printing medium.

[0102] To enable the printing medium entering the material receiving platform 3 to be stopped and constrained by the stop assembly 2, when the material receiving platform 3 rises to the highest position on the material receiving frame 1, the bearing plane 31 of the material receiving platform 3 should form an interleaved fit with the structure of the material blocking cross beam 22 of the stop assembly 2 in the up-down position (as Figure 4 , Figure 14 shown), and the structure of the material blocking cross beam 22 should be able to cover the path of the printing medium entering the material receiving platform 3 in the positive projection in the horizontal direction - that is, the outlet of the following discharge path offset mechanism 6, as Figure 4 , Figure 5 shown. Therefore, a plurality of downwardly protruding material blocking protrusions 23 are arranged at intervals at the bottom of the material blocking cross beam 22. The downward protruding height of these material blocking protrusions 23 can at least cover the outlet of the following discharge path offset mechanism 6 in the positive projection in the horizontal direction. The surfaces of these material blocking protrusions 23 that face the printing medium are of a coplanar structure, and the arrangement distance between adjacent material blocking protrusions 23 is less than the transverse width dimension of the printing medium in the conveying direction, so that the printing medium entering the material receiving platform 3 can at least cover two material blocking protrusions 23 in the transverse width direction in the conveying direction, as Figure 14 shown. When the above-mentioned material receiving platform 3 rises to the highest position on the material receiving frame 1, an interleaved fit is formed between the bearing plane 31 of the material receiving platform 3 and the lowest end of the material blocking protrusion 23. The surfaces of the material blocking protrusions 23 that face the printing medium are above the bearing plane 31 of the material receiving platform 3, constituting a space for stacking and piling up each sheet of printing medium that sequentially enters.

[0103] From the cooperation structure of the above-mentioned material receiving platform 3 and the stop component 2, it can be seen that the material receiving platform 3 cooperates with the stop component 2 to stack and collect each sheet of printing medium entering in sequence, so that the printing medium entering the material receiving platform 3 is positioned under the restraint of the material blocking protrusion 23 of the stop component 2, so that each sheet of printing medium entering in sequence is stacked and aligned with the material blocking protrusion 23 as the reference in the advancing direction.

[0104] To adapt to the stacking and collection of printing media of different specifications, both ends of the material blocking cross beam 22 of the above-mentioned stop component 2 are assembled on the material blocking bracket 21 in a slidable structure through corresponding sliders 24, so that it can be displaced relative to the printer body 9 on the material blocking bracket 21, such as Figure 3 、 Figure 4 、 Figure 7 、 Figure 13 、 Figure 14 shown. At the same time, based on the dislocation cooperation relationship between the material blocking protrusion 23 at the bottom of the above-mentioned material blocking cross beam 22 and the material receiving platform 3, in order to adapt to the relative displacement of the material blocking cross beam 22, at the bearing plane 31 of the above-mentioned material receiving platform 3, a plurality of relief grooves 32 are opened along the conveying direction of the printing medium and matching the material blocking protrusions 23 on the material blocking cross beam 22 to pass through, such as Figure 1 、 Figure 7 、 Figure 13 、 Figure 14 、 Figure 16 shown. According to this cooperation structure, when the material receiving platform 3 rises to the highest position, the material blocking protrusion 23 at the bottom of the material blocking cross beam 22 is inserted into the relief groove 32 of the material receiving platform 3, such as Figure 14 shown. From the passing-through cooperation structure of the material blocking protrusion 23 and the relief groove 32, it can be seen that it neither hinders the stacking and collection of the printing medium entering the bearing plane 31 of the material receiving platform 3, such as Figure 16 shown, nor can the material blocking cross beam 22 be relatively slid to adjust the collection space of different sizes.

[0105] In order to keep the printing medium stacked on the material receiving platform 3 stable and prevent drift, rotatable pressure rollers 25 for preventing the printing medium entering the material receiving platform 3 from drifting are arranged at intervals on the front side of the above-mentioned material blocking cross beam 22. The pressure rollers 25 form a channel for the printing medium to enter the material receiving platform 3 and stack during rotation along the advancing direction of the printing medium, especially in cooperation with the following second pressure transmission mechanism 8, such as Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 13 、 Figure 14As shown in the figure. Based on this, the relative position of the pressure roller 25 and the material stop cross beam 22 should be such that the material stop cross beam 22 is at the head of the printing medium in the traveling direction of the current stack, and the pressure roller 25 is at the middle of the printing medium in the traveling direction of the current stack. To adapt to the slidability of the above-mentioned material stop cross beam 22, the pressure roller 25 is assembled on the slider 24 where the material stop cross beam 22 is located.

[0106] Based on the above-mentioned material receiving structure, to ensure that the printing medium smoothly enters the material receiving platform 3, prevent curling and drifting, and ensure the neatness of the stacked pile, on the material receiving frame 1 above the above-mentioned material receiving platform 3, a second pressure feeding transmission mechanism 8 that is driven along the conveying direction of the printing medium is also arranged, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 15 , Figure 17 and Figure 18 shown. The second pressure feeding transmission mechanism 8 has a front shaft that first cooperates with the currently conveyed printing medium, that is, the third shaft 81, a rear shaft that then cooperates with the currently conveyed printing medium, that is, the fourth shaft 82, and a plurality of second medium guiding belts 83 that are sleeved between the third shaft 81 and the fourth shaft 82 and are circulated and driven. These second medium guiding belts 83 are arranged at intervals along the axial directions of the third shaft 81 and the fourth shaft 82, and the arrangement positions of each second medium guiding belt 83 basically correspond to the positions where the material stop protrusions 23 of the above-mentioned material stop cross beam 22 are located. The pressure roller 25 on the front side of the above-mentioned material stop cross beam 22 is in the circulating driving space of the second medium guiding belt 83 and is in contact and cooperation with the second medium guiding belt 83 that is circulated and driven to the bottom side. The aforementioned third shaft 81 or the fourth shaft 82 serves as the driving shaft that acts as the driven component, driving the second medium guiding belt 83 and other associated shafts to rotate along the conveying direction of the printing medium. During the circulating driving process of the second medium guiding belt 83, it cooperates with the lower material receiving platform 3 and the upper stacked medium to form a channel that can allow the currently conveyed printing medium to enter and prevent drifting; usually, to ensure the reliability of the printing medium entering this conveying channel, the arrangement position of the third shaft 81 of the second pressure feeding transmission mechanism 8 is slightly higher than the arrangement position of the fourth shaft 82. Of course, this height difference is relatively small and not obvious.

[0107] For the above-mentioned material receiving structure, the printing medium output by the printer body 9 forms a neat stack at the traveling head in the traveling direction. If the printing medium output by the printer body 9 enters the material receiving platform 3 along the same trajectory, it will also form a neat stack in the transverse direction relative to the traveling direction, so as to form a neat stack on all four sides of the traveling direction, front, back, left, and right.

[0108] In order to classify and stack the printing media during a large - batch continuous printing process, that is, to form a classified stack according to the set number of copies (one copy as a set of stacking units) for subsequent sorting operations, it is necessary to form a horizontally staggered stack along the height direction of the printing media stacked on the receiving platform 3 during the continuous material receiving process, as Figure 16 shown by the horizontally staggered stacked medium C. Therefore, the discharge path offset mechanism 6 exists in cooperation with the above - mentioned receiving platform 3 and the material blocking assembly 2, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 15 , Figure 17 and Figure 18 shown.

[0109] The discharge path offset mechanism 6 is arranged on the receiving frame 1 upstream of the receiving platform 3 and is used to sequentially connect the printing medium conveying path of the printer body 9. The discharge path offset mechanism 6 can be translated horizontally along the transverse direction of the printing medium conveying direction to perform a translation movement on the printing medium conveying path, thereby changing the traveling trajectory of the printing medium entering the receiving platform 3 in the transverse direction of the printing medium conveying direction. Through the change of different traveling trajectories, the printing medium entering the receiving platform 3 forms a horizontally staggered stack as Figure 16 shown, that is, the finally formed stack structure is the horizontally staggered stacked medium C.

[0110] More specifically, the discharge path offset mechanism 6 has an inclined roller conveying mechanism 61 and a wind force mechanism 3, as Figure 3 and Figure 4 shown.

[0111] As Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12As shown in the figure, the inclined roller conveying mechanism 61 has a crossover plate 611 connected to the discharge port of the printer body 9. A plurality of driving inclined rollers 616 that are rotatable and are sequentially assembled in the opening area of the crossover plate 611 along the printing medium conveying direction. At one end of these driving inclined rollers 616, there is a guiding edge baffle 612 arranged along the printing medium conveying direction to guide and convey the incoming printing medium. These driving inclined rollers 616 are assembled on the receiving frame 1 in a rotatable structure on the same plane. The same fitting clearance and inclination angle are basically maintained between adjacent driving inclined rollers 616. Each driving inclined roller 616 is in an acute angle relationship with the guiding edge baffle 612 in the printing medium conveying direction. The specific included angle is selected within the range of 70° to 85°, preferably 80°. This included angle should not be too large or too small, so that the conveyed printing medium entering the inclined roller conveying mechanism 61 moves forward along the guiding edge baffle 612 under the rotation of each driving inclined roller 616 and enters the receiving platform 3 with the guiding edge baffle 612 as the forward reference. The aforementioned crossover plate 611 and the driving inclined rollers 616 constitute the conveying working surface for the inclined roller conveying mechanism 61 to convey the printing medium.

[0112] The above-mentioned inclined roller conveying mechanism 61 also has a rotation driving assembly 618 for driving these driving inclined rollers 616 to rotate. The rotation driving assembly 618 is mainly composed of a motor, a synchronous pulley, a tensioning pulley, and a synchronous belt. The motor, the synchronous pulley, and the tensioning pulley are assembled on the receiving frame 1 below the driving inclined rollers 616. The output shaft of the motor is connected to the synchronous pulley. The synchronous belt is sleeved between the synchronous pulley and the tensioning pulley. The inner ring wall surface of the synchronous belt is meshed with the synchronous pulley and the tensioning pulley in a toothed structure. The outer ring wall surface of the synchronous belt is in frictional cooperation with each driving inclined roller 616. During the transmission of the synchronous belt, each driving inclined roller 616 is frictionally driven to rotate, as Figure 4 shown.

[0113] Since the above-mentioned inclined roller conveying mechanism 61 is used to guide the traveling track of the printing medium entering the receiving platform 3 to ensure that the printing medium enters the receiving platform 3 along the track of the guiding edge baffle 612, and since it is necessary to change the traveling track of the printing medium entering the receiving platform 3, therefore, the above-mentioned guiding edge baffle 612 is not fixedly arranged on the receiving frame 1, and its position can be horizontally translated relative to the driving inclined rollers 616. Based on this, the guiding edge baffle 612 is movably assembled on the receiving frame 1 through a sliding driving assembly 614 (composed of a motor and a rack, a fixed motor drives a movable rack through a gear) and a plurality of linear sliding assemblies 613 (composed of a slide rail and a slider). Guided by the linear sliding assembly 613, under the drive of the sliding driving assembly 614, the guiding edge baffle 612 performs a translational movement on the receiving frame 1 along the linear sliding assembly 613, so as to approach or move away from the end of the corresponding driving inclined roller 616, thereby changing the reference position for the driving inclined rollers 616 to convey along the edge, as Figure 3 、Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 as shown.

[0114] That is to say, for the diagonal roller conveying mechanism 61 with the above structure, the cross-bridge plate 611 and the driving diagonal roller 616 are relatively fixed on the material receiving frame 1 (except for the rotational movement of the driving diagonal roller 616), and cannot be horizontally translated. The guiding side baffle 612 is movably assembled on the material receiving frame 1 and can perform a horizontal translation movement at the corresponding end of the driving diagonal roller 616.

[0115] Due to the characteristic of the diagonal roller conveying mechanism 61 for conveying the incoming printing medium to the side and the need to lean against the guiding side baffle 612; and since the guiding side baffle 612 is movably assembled relative to the cross-bridge plate 611 and the driving diagonal roller 616, there is a horizontal translation clearance for the guiding side baffle 612, which will cause blockage to the printing medium conveyed to the side. Therefore, the area of the cross-bridge plate 611 adjacent to the guiding side baffle 612 has a flat edge forming a planar structure, such as Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 as shown; the bottom of the guiding side baffle 612 has a baffle transition bottom edge 617 with a bent structure, and the baffle transition bottom edge 617 is horizontally nested and fitted at the bottom edge of the side of the cross-bridge plate 611 that cooperates with the guiding side baffle 612, such as Figure 12 as shown. Driven by the sliding drive assembly 614, when the guiding side baffle 612 performs a translation movement in the horizontal direction of the printing medium conveying direction, the baffle transition bottom edge 617 and the corresponding edge of the cross-bridge plate 611 are fitted in a nested relationship, which also enables the guiding side baffle 612 to have a limited horizontal offset adjustment distance H in the horizontal direction. The value of the horizontal offset adjustment distance H is usually in the range of 5 - 20 mm, and the guiding side baffle 612 can perform horizontal translation adjustment within the range of the horizontal offset adjustment distance H to meet the technical requirements of the horizontal misalignment distance for the horizontal misaligned stacking of the printing medium. In the above-mentioned matching structure, the printing medium conveyed through the cross-bridge plate 611 and the driving diagonal roller 616 abuts against the guiding side baffle 612 with one side edge in its advancing direction. Since the horizontal translation clearance of the guiding side baffle 612 is at the bottom of the cross-bridge plate 611, it will not cause blockage to the conveyance of the printing medium due to the horizontal translation of the guiding side baffle 612.

[0116] In order to make the lateral translation movement of the guide edge stop 612 of the above-mentioned inclined roller conveying mechanism 61 adapt to the high-speed conveying of the printing medium and form an automated operation, the above-mentioned discharge path offset mechanism 6 has a translation automatic control system for controlling the lateral translation movement of the inclined roller conveying mechanism 61. The translation automatic control system mainly consists of a counting sensor 7, a sliding stroke sensor 615, a driving motor constituting the sliding drive assembly 614, and a controller.

[0117] More specifically, the counting sensor 7 is arranged at the output end of the discharge path offset mechanism 6. Specifically, it is embedded in the downstream part of the crossover plate 611 of the inclined roller conveying mechanism 61, close to the guide edge stop 612. When the printing medium conveyed along the guide edge stop 612 enters the receiving platform 3 after exiting the inclined roller conveying mechanism 61, it will necessarily pass through the detection range of the counting sensor 7. The counting sensor 7 is used to detect the number of printing media sequentially entering the receiving platform 3 and feedback the detection signal to the controller according to the set counting period (for example, 20 sheets are taken as a group to form a stacking unit, then the counting sensor 7 resets after accumulating 20 sheets and starts accumulating again). The sliding stroke sensor 615 is arranged at the above-mentioned linear sliding assembly 613 and is used to detect the lateral translation movement stroke position of the guide edge stop 612 driven by the sliding drive assembly 614 and feedback the detection signal to the controller. The driving motor constituting the sliding drive assembly 614, under the control command of the controller, is used to drive the sliding drive assembly 614 to act according to the set movement direction and stroke, so as to drive the lateral translation reciprocating movement of the guide edge stop 612.

[0118] For example, assume that the laterally offset stacking medium C collected and stacked on the receiving platform 3 is composed of multiple groups of stacked units that are offset in the lateral direction. The offset distance between adjacent two groups of stacked units in the lateral direction is 10 mm, and each group of stacked units is composed of 20 sheets of printing media stacked on top of each other. Thus, under the control of the translation automatic control system, the guiding edge stop 612 is at a set position 1, and the conveyed printing media travels and outputs with the guiding edge stop 612 as a reference. During this output process, the counting sensor 7 counts the output printing media until it counts to 20 sheets and feeds back a signal to the controller; based on this signal, the controller instructs the guiding edge stop 612 to laterally translate to a set position 2. The distance between the set position 2 and the set position 1 is 10 mm in the lateral direction. When the guiding edge stop 612 is at the set position 2, the conveyed printing media travels and outputs with the guiding edge stop 612 as a reference. During this output process, the counting sensor 7 counts the output printing media until it counts to 20 sheets and feeds back a signal to the controller; based on this signal, the controller instructs the guiding edge stop 612 to laterally translate to the set position 1, and so on. Thus, through the lateral translation of the guiding edge stop 612, the traveling trajectory of the printing media guided into the receiving platform 3 is changed, so that the printing media sequentially entering the receiving platform 3 are stacked in a laterally offset manner according to the setting, and finally the laterally offset stacking medium C is formed.

[0119] That is to say, in this embodiment, for the inclined roller conveying mechanism 61 that constitutes the discharge path offset mechanism 6, the relative positions of its cross-bridge plate 611 and driving inclined rollers 616 on the receiving frame 1 are fixed, and only the guiding edge stop 612 can laterally translate. Therefore, the motor that constitutes the sliding drive assembly 614, under the control instruction of the controller, is used to drive the sliding drive assembly 614 to act according to the set motion direction and stroke, so as to drive the guiding edge stop 612 of the discharge path offset mechanism 6 to perform a lateral translation reciprocating motion.

[0120] As Figure 2 、 Figure 3 、 Figure 15 shown, the wind force mechanism 62 is arranged above the above-mentioned inclined roller conveying mechanism 61 and is used to apply a lateral local force to the conveyed printing media in the traveling direction at the guiding edge stop 612 of the inclined roller conveying mechanism 61, so as to force the printing media to accelerate towards the edge during the conveying process on the inclined roller conveying mechanism 61.

[0121] Specifically, the wind mechanism 62 has a fan bracket 621 and multiple groups of small electric fans 622 arranged on the fan bracket 621. The fan bracket 621 is supported and fixed on the material receiving frame 1 and is located above the inclined roller conveying mechanism 61. Each group of small electric fans 622 is arranged on the fan bracket 621 along the printing medium conveying direction, and the arrangement positions of these small electric fans 622 basically correspond to the longitudinal length of the conveying working surface of the inclined roller conveying mechanism 61. The air outlet of the wind mechanism 62 faces the conveying working surface of the inclined roller conveying mechanism 61, and the direct conveying path of the wind blown by the wind mechanism 62, with the guiding edge baffle 612 as the reference benchmark, is in a right-angle relationship with the acting plane of the inclined roller conveying mechanism 61. That is to say, the direct conveying path of the wind blown by the wind mechanism 62 is basically parallel to the guiding surface of the guiding edge baffle 612.

[0122] In the above-mentioned cooperation relationship between the wind mechanism 62 and the inclined roller conveying mechanism 61, the wind blown by the wind mechanism 62 cannot cover the lateral width of the currently conveyed printing medium in the lateral direction (with the printing medium conveying direction as the longitudinal direction) of the inclined roller conveying mechanism 61, and can only act on the area of the currently conveyed printing medium close to the guiding edge baffle 612. That is, the direct acting area of the wind blown by the wind mechanism 62 within the conveying working surface of the inclined roller conveying mechanism 61 should be close to the guiding edge baffle 612, so as to cooperate with the inclined roller conveying mechanism 61 to generate a strong lateral side-leaning component torque on the conveyed printing medium, forcing the printing medium to quickly lean against the side during the inclined roller conveying, and thus ensuring that the printing medium output by the above-mentioned inclined roller conveying mechanism 61 all travels along the guiding edge baffle 612 to the material receiving platform 3.

[0123] Taking the stacked paper printed by a conventional high-speed printer using A3 paper or A4 paper as an example, regardless of whether the paper is conveyed forward with the length direction or the width direction of the paper as the paper head, the direct acting area of the wind blown by the wind mechanism 62 on the conveying working surface of the inclined roller conveying mechanism 61 should be within a range of 200 mm, preferably within 150 mm, transversely to the paper conveying direction with the guiding edge baffle 612 as the benchmark. That is, when acting on the currently conveyed printing medium, it is within a range of 200 mm transversely to the printing medium conveying direction with the guiding edge baffle 612 as the benchmark. In other words, the transverse width of the direct wind acting area starts from the guiding edge baffle 612 and has a maximum value of 200 mm. When the currently conveyed printing medium is conveyed to the inclined roller conveying mechanism 61, the wind blown by the wind mechanism 62 acts on the area of the current printing medium close to the guiding edge baffle 612, and during the continuous conveying of the inclined roller conveying mechanism 61, it forces the currently conveyed printing medium to accelerate and lean against the side with the guiding edge baffle 612 as the alignment benchmark on the inclined roller conveying mechanism 61.

[0124] Each small electric fan 622 of the above-mentioned wind power mechanism 62 can be driven synchronously by the same motor, or independently driven by different motors but operate cooperatively. Regardless of which operating mode, ultimately, the wind pressure of the wind blown by each small electric fan 622 of the wind power mechanism 62 directly acting on the currently conveyed printing medium should be controlled within the range of 2 to 50 Pa, preferably within the range of 5 to 10 Pa. The setting of the wind pressure of the wind power mechanism 62 acting on the printing medium specifically should be based on the material stiffness of the currently used printing medium. Generally, the smaller the stiffness of the printing medium, the smaller the wind pressure it can adapt to, and the larger the stiffness of the printing medium, the larger the wind pressure it can adapt to. The stiffness of the printing medium is related to the grammage, manufacturing process, etc. of the printing medium. The wind pressure range of 5 to 10 Pa can basically meet the reliable and stable transmission of papers with different grammages (60 to 300 grams) used in conventional printers.

[0125] On the basis of the structure of the above-mentioned discharge path offset mechanism, in order to ensure the smooth conveyance of the printing medium to the side to prevent the printing medium from curling and drifting and to ensure the reliability of side conveyance, on the receiving frame 1 above the above-mentioned inclined roller conveyance mechanism 61, there is also arranged a first pressure material drive mechanism 5 that drives along the conveyance direction of the printing medium, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 15 , Figure 17 and Figure 18 shown. The first pressure material drive mechanism 5 has a first shaft - that is, the first shaft 51, which first cooperates with the front shaft of the currently conveyed printing medium, and a second shaft - that is, the second shaft 52, which then cooperates with the rear shaft of the currently conveyed printing medium, as well as a plurality of first medium guide belts 53 that are sleeved between the first shaft 51 and the second shaft 52 and circulate and drive. These first medium guide belts 53 are arranged at intervals along the axial directions of the first shaft 51 and the second shaft 52. The aforementioned first shaft 51 or the second shaft 52 serves as the driving shaft that acts as the driven component, driving the first medium guide belts 53 and other associated shafts to rotate along the conveyance direction of the printing medium. During the process of circulating and driving, the first medium guide belts 53 cooperate with the conveyance working surface of the inclined roller conveyance mechanism 61 below to form a channel that allows the currently conveyed printing medium to enter and prevent drifting. Generally, to ensure the reliability of the printing medium entering this conveyance channel, the arrangement position of the first shaft 51 of the first pressure material drive mechanism 5 is slightly higher than the arrangement position of the second shaft 52. Of course, this height difference is relatively small and not obvious. In this way, the above-mentioned wind power mechanism 62 is arranged within the circulating drive space of the first medium guide belts 53 of the first pressure material drive mechanism 5.

[0126] In the above-mentioned material receiving structure, the initial height position of the material receiving platform 3 is lower than the discharge port of the discharge path offset mechanism (inclined roller conveying mechanism) (usually with a height difference of about 20 mm). The second material pressing transmission mechanism 8 of the above structure needs to form a channel for the printing medium to enter with the bearing plane 31 of the material receiving platform 3, and the first material pressing transmission mechanism 5 of the above structure needs to form a channel for the printing medium to enter with the conveying working surface of the inclined roller conveying mechanism 61. Therefore, the first material pressing transmission mechanism 5 of the above structure and the second material pressing transmission mechanism 8 of the above structure are arranged on the material receiving frame 1 in a slightly inclined structure with the upstream slightly higher and the downstream slightly lower. If the first material pressing transmission mechanism 5 and the second material pressing transmission mechanism 8 are arranged completely independently on the material receiving frame 1, there is usually an interruption space in the sequential direction between the first material pressing transmission mechanism 5 and the second material pressing transmission mechanism 8, which may form a gap for the printing medium to deviate from the set conveying channel during conveying. For this reason, the second shaft 52 of the first material pressing transmission mechanism 5 of the above structure and the third shaft 81 of the second material pressing transmission mechanism 8 of the above structure are staggered with each other in the front and back in the direction of printing medium conveying, that is, the third shaft 81 of the second material pressing transmission mechanism 8 contacts the current printing medium before the second shaft 52 of the first material pressing transmission mechanism 5, that is, the second shaft 52 of the first material pressing transmission mechanism 5 is basically above the feed port of the material receiving platform 3, and the third shaft 81 of the second material pressing transmission mechanism 8 is basically above the discharge port of the inclined roller conveying mechanism 61. In this way, the first medium guiding belt 53 of the first material pressing transmission mechanism 5 bypasses the third shaft 81 of the second material pressing transmission mechanism 8 and is sleeved on the second shaft 52 of the first material pressing transmission mechanism 5. Similarly, the second medium guiding belt 83 of the second material pressing transmission mechanism 8 bypasses the second shaft 52 of the first material pressing transmission mechanism 5 and is sleeved on the third shaft 81 of the second material pressing transmission mechanism 8, as Figure 2 , Figure 3 , Figure 4As shown. Of course, based on the slightly inclined arrangement structure of the above-mentioned first blanking transmission mechanism 5 and the second blanking transmission mechanism 8, the arrangement position of the second shaft 52 of the first blanking transmission mechanism 5 is slightly lower than that of the third shaft 81 of the second blanking transmission mechanism 8; however, based on the cooperation relationship between the above-mentioned first blanking transmission mechanism 5 and the second blanking transmission mechanism 8, and based on the fact that the initial position of the bearing plane 31 of the material receiving platform 3 is lower than the conveying working surface of the inclined roller conveying mechanism 61, in order to adapt to the height difference between the conveying working surface of the inclined roller conveying mechanism 61 and the bearing plane 31 of the material receiving platform 3, and to form a reliable conveying channel, the height difference in the arrangement positions between the second shaft 52 of the first blanking transmission mechanism 5 and the third shaft 81 of the second blanking transmission mechanism 8 becomes relatively obvious; in this arrangement structure with an obvious height difference, there is a risk of position interference between the first medium guiding belt 53 and the second medium guiding belt 83 between the second shaft 52 and the third shaft 81 and the relatively high-position inclined roller conveying mechanism 61. Therefore, an intermediate shaft is provided at the bottom side at the connection between the first blanking transmission mechanism 5 and the second blanking transmission mechanism 8. This intermediate shaft is arranged at the bottom side of the area between the second shaft 52 and the third shaft 81 to deflect and tension the first medium guiding belt 53 and the second medium guiding belt 83, as Figure 4 and Figure 5 shown.

[0127] Based on the above-mentioned linkage cooperation relationship between the first blanking transmission mechanism 5 and the second blanking transmission mechanism 8, the two adopt the same driving component. The driving component is connected to any one shaft as the driving shaft, and the other shafts are driven as driven shafts through the medium guiding belt to operate.

[0128] In the above technical solution, based on automatic control, the controllers of the above-mentioned material receiving automatic control system (lifting automatic control system) and the translation automatic control system can be integrated into the same controller and operate according to their respective control logics, and they do not necessarily have to be arranged independently of each other. Of course, they can also be arranged independently of each other.

[0129] Embodiment 2 Other contents of this embodiment are the same as those of Embodiment 1, and the difference lies in: the inclined roller conveying mechanism that constitutes the discharge path offset mechanism.

[0130] Specifically, the inclined roller conveying mechanism has an inclined roller bracket assembled on the receiving frame in a lateral translation structure, multiple driving inclined rollers sequentially assembled on the inclined roller bracket along the printing medium conveying direction and capable of rotating, a crossover plate assembled on the inclined roller bracket and located outside the driving inclined rollers, a guiding edge stop arranged along the printing medium conveying direction at one end of these driving inclined rollers for guiding and conveying the incoming printing medium, a sliding driving assembly for driving the inclined roller bracket to perform a lateral translation movement along the printing medium conveying direction on the receiving frame, and a rotation driving assembly for driving these driving inclined rollers to rotate along the set conveying direction; the guiding edge stop is fixedly connected to the inclined roller bracket and has a relatively fixed structure with the driving inclined rollers and the crossover plate and cannot be displaced.

[0131] Compared with Embodiment 1, in this embodiment, the entire inclined roller conveying mechanism is laterally translated to change the traveling trajectory of the printing medium conveyed along the edge. That is to say, in this embodiment, the motor constituting the sliding driving assembly, under the control instruction of the controller, is used to drive the sliding driving assembly to act according to the set motion direction and stroke, so as to drive the inclined roller conveying mechanism of the discharge path offset mechanism to perform a lateral translation reciprocating motion as a whole.

[0132] In this embodiment, since the lateral translation distance of the inclined roller conveying mechanism is relatively small, that is, it reciprocates within the range of 5 - 20 mm, the wind mechanism and the first pressing and driving mechanism cooperating with the inclined roller conveying mechanism can be directly arranged on the receiving frame and do not translate with the translation of the inclined roller conveying mechanism. Of course, the wind mechanism and the first pressing and driving mechanism can also be arranged on the inclined roller bracket and translate with the lateral translation of the inclined roller conveying mechanism. At this time, the first pressing and driving mechanism should not be connected to the second pressing and driving mechanism above the receiving platform.

[0133] Embodiment 3 Other contents of this embodiment are the same as those of Embodiment 1, and the differences are as follows: Regarding the direct conveying path of the wind blown by the wind mechanism, with the guiding edge stop of the inclined roller conveying mechanism as the reference benchmark, it cooperates with the working plane of the inclined roller conveying mechanism at an obtuse angle. That is to say, the extension line of the direct conveying path of the wind blown by the wind mechanism and the extension line of the guiding surface of the guiding edge stop are in an acute angle cooperation relationship. Of course, the direct conveying path of the wind blown by the wind mechanism should not act on the guiding edge stop.

[0134] In this embodiment, due to the increase in height caused by the inclined arrangement of the small electric fan on the fan bracket for the wind mechanism, the wind mechanism is arranged above the first pressing and driving mechanism (if the space formed by the circulating transmission of each medium guiding belt of the first pressing and driving mechanism is large enough, it can also be installed in the space formed by the circulating transmission of each medium guiding belt of the first pressing and driving mechanism).

[0135] Embodiment 4 The other contents of this embodiment are the same as those of Embodiment 1, except that: The wind mechanism is arranged below the inclined roller conveying mechanism, and generates negative pressure adsorption on the air outlet, thereby generating a force on the printing medium conveyed by the inclined roller conveying mechanism in the form of negative pressure adsorption.

[0136] Of course, since the first material pressing transmission mechanism can only be located above the inclined roller conveying mechanism, the coordination relationship between the wind power mechanism and the first material pressing transmission mechanism is cancelled.

[0137] In addition, if the direct action path of the wind force generated by the wind mechanism is arranged obliquely with reference to the guide edge, it cooperates with the action surface of the printing medium transported by the inclined roller conveying mechanism at an acute angle, that is, the air outlet obliquely adsorbs the inclined roller conveying mechanism near the guide edge.

[0138] Example 5 The other contents of this embodiment are the same as those of Embodiment 1, except that: The material blocking protrusion at the bottom of the material blocking cross beam is removed, and the bottom of the material blocking cross beam is formed into an integral stop structure for receiving the printing medium.

[0139] Based on this, if the blocking beam of this embodiment slides forward, a large area of ​​​​a gap needs to be formed at the bearing plane of the receiving platform, which will inevitably damage the bearing function of the bearing plane for the printing medium. Therefore, in this embodiment, the blocking beam is fixed on the blocking bracket and cannot slide, that is, the slider structure is removed.

[0140] Correspondingly, the clearance groove on the material receiving platform can be removed; the pressing roller of the stopper assembly is directly assembled on the material stopper bracket in a rotatable structure.

[0141] Example 6 The other contents of this embodiment are the same as those of Embodiment 1, except that: The receiving platform does not extend out of the receiving frame; A slide groove for the sliding movement of the stop assembly is formed on the receiving frame. The stop beam and the pressure roller of the stop assembly are directly assembled on the receiving frame through a slider, and the stop bracket of the stop assembly is removed.

[0142] Example 7 The other contents of this embodiment are the same as those of Embodiment 1, except that: The guide side block of the inclined roller conveying mechanism is driven by a screw drive pair structure / synchronous belt drive structure for linear translation.

[0143] Similarly, the material receiving platform is driven by a rack transmission structure / synchronous belt transmission structure to move up and down linearly.

[0144] Example 8 The other contents of this embodiment are the same as those of Embodiment 1, except that: The wind mechanism of the discharge path offset mechanism is removed, and the discharge path offset mechanism is only conveyed by the inclined roller conveying mechanism close to the side.

[0145] Of course, the corresponding functions after the removal of the wind mechanism are eliminated accordingly.

[0146] Embodiment 9 The other contents of this embodiment are the same as those of Embodiment 1, except that: The counting sensors of the translation automatic control system are arranged upstream of the inclined roller conveying mechanism.

[0147] Embodiment 10 The other contents of this embodiment are the same as those of Embodiment 1, except that: The counting sensors of the translation automatic control system are arranged upstream of the inclined roller conveying mechanism.

[0148] Embodiment 11 The other contents of this embodiment are the same as those of Embodiment 1, except that: There are two groups of counting sensors for the translation automatic control system. One group is arranged upstream of the inclined roller conveying mechanism, and the other group is arranged downstream of the inclined roller conveying mechanism. Among them, the upstream counting sensor is used to perform periodic counting on the advancing printing medium, and the downstream sensor is used to detect the output end of the last printing medium in the current counting cycle to determine that when all the printing media in the current counting cycle are output from the inclined roller conveying mechanism, the inclined roller conveying mechanism performs corresponding horizontal translation actions.

[0149] Based on this, the counting sensors of the translation automatic control system can also be linked with the printing control system of the printer body. For example, taking a set of stacking units as a set of printing objects, setting the number of sheets printed for each set for the printing control system of the printer body. The printing control system performs periodic counting on the printed printing media according to the number of sheets printed for each set, and the downstream sensor is used to detect the output end of the last printing medium in the current counting cycle.

[0150] Or, directly let the printing control system of the printer body perform periodic counting and detection on the printing media of the stacking unit, and cancel the counting sensors arranged at the receiving device. For example, taking a set of stacking units as a set of printing objects, setting the number of sheets printed for each set for the printing control system of the printer body. The printing control system performs periodic counting on the printed printing media according to the number of sheets printed for each set, and delays the feedback signal to the translation automatic control system according to the set conveying efficiency.

[0151] Embodiment 12 The other contents of this embodiment are the same as those of Embodiment 1 or 2, except that: The transmission inclined roller structure of the inclined roller conveying mechanism is replaced by an obliquely driven belt structure, that is, the inclined roller conveying mechanism is changed to an obliquely driven belt conveying mechanism.

[0152] This substitution in this embodiment is only a replacement of the transmission structure for side-by-side conveying of the inclined roller conveying mechanism, and the original structures are adopted for the lateral displacement structure of the remaining guiding side baffle or the overall lateral displacement structure of the inclined roller conveying mechanism (oblique conveying mechanism).

[0153] Regarding the replacement of the transmission inclined roller structure with a belt structure, two shafts are arranged at intervals in the conveying direction on the corresponding bracket, and a conveyor belt is sleeved on the two shafts; it is required that the two shafts respectively form an acute angle mating relationship with the guiding side baffle in the printing medium conveying direction.

[0154] Embodiment 13 Other contents of this embodiment are the same as those of Embodiment 1 or 2, and the differences are as follows: The discharge path offset mechanism is arranged upstream of the receiving platform with the main frame of the printer body as the supporting carrier and cooperates with the receiving platform.

[0155] That is to say, in this embodiment, the discharge path offset mechanism is independent of the receiving frame where the receiving platform is located, but is arranged on the main frame of the printer body, at the tail of the sequential conveying path of the printer body, and the receiving frame is arranged at the discharge port of the discharge path offset mechanism, that is, the discharge path offset mechanism on the main frame cooperates with the receiving platform on the receiving frame.
