[0001] The present invention relates to the field of printing technology, and in particular to a printing medium buffer transmission device and a printing equipment. Background Art

[0002] The printing device prints patterns on the printing medium by spraying ink. The existing printing device generally includes a conveying device for transmitting the printing medium. The transmission device sequentially transmits the printing medium to each station for processing, such as printing, curing and other stations. The current transmission device usually adopts the transmission method of the assembly line to transmit the printing medium so that the printing medium is transmitted along the transmission direction of the transmission device. However, in some printing processes, a certain time interval is required between two adjacent processes so that the previous process can have enough time to react before the next process. The existing printing device usually extends the length of the transmission device between the two stations so that the printing medium is transmitted over a certain distance to achieve a certain time interval between the two adjacent stations. However, when the required interval time is long, the transmission device occupies a large area, which makes the entire device larger. Therefore, the existing printing device has a large volume technical problem. Summary of the invention

[0003] In view of this, an embodiment of the present invention provides a print medium buffer transmission device and a printing device, so as to solve the technical problem that the transmission device in the existing printing device has a large volume.

[0005] Furthermore, the transmission mechanism includes: a driving component and a transmission member; the output end of the driving component is transmission-connected to the transmission member, the receiving mechanism is connected to the transmission member, and the driving component drives the transmission member to drive the receiving mechanism to move.

[0006] Furthermore, two conveying members are provided, and the two conveying members are respectively connected to opposite sides of the receiving mechanism.

[0007] Furthermore, the two conveying members are arranged around the bending portion and are staggered.

[0008] Furthermore, for the same receiving mechanism, one of the diagonal corners of the receiving mechanism is connected to a transmission member, and the other diagonal corner of the receiving mechanism is connected to another transmission member.

[0009] Furthermore, the conveying member forms a closed loop around the path of the bending portion to transmit the receiving mechanism.

[0013] In a second aspect, the present invention provides a printing device, the device comprising the print medium buffer transmission device as described in any one of the above.

[0014] In summary, the beneficial effects of the present invention are as follows:

[0015] On the one hand, the receiving mechanism can carry and transport the printing medium. A bending portion bent along the longitudinal direction is provided on the bracket. The transmission mechanism moves along the bending portion to transport the printing medium in the transverse and longitudinal directions. The transmission device can lengthen the path of the printing medium under the same footprint or length of the transmission device (this length can be interpreted as the distance between the feeding end and the output end of the transmission device). The movement time is lengthened so that the movement time of the printing medium between two adjacent workstations meets the required time; that is, the transmission path of the printing medium is lengthened, and the footprint of the entire transmission device or the length of the transmission device is reduced (when the bending portion is bent along the longitudinal direction, the footprint of the transmission device is reduced; if the bending portion is bent along the transverse direction, the length of the transmission device is reduced); thereby reducing the volume of the entire transmission device, making the structure of the entire transmission device more compact, solving the technical problem of large volume in existing printing equipment, and having the advantages of compact structure and small footprint.

[0030] The following is combined with Figure 1 -Attached Fig. 9 The present invention is described in further detail.

[0031] On one hand, an embodiment of the present invention provides a print medium buffering and transporting device, which is used in a printing device. The print medium buffering and transporting device is arranged between two workstations in the printing device to buffer and transport print media, so that the print media is leveled on the structure, the leveling time is guaranteed, and the volume of the print medium buffering and transporting device is reduced. Figure 1 As shown, the print medium buffer transmission device includes: a bracket 4, the bracket 4 is provided with a bending portion; a receiving mechanism 3, carrying the print medium; a transmission mechanism, which is arranged around the bending portion 1 of the bracket 4, and is used to transmit the receiving mechanism along the bending portion 1 (see Figure 4 ) to transmit.

[0032] In this embodiment, due to the viewing angle occlusion relationship, in this embodiment, Figure 4What is shown is the bending part 1 formed by the winding of the transmission mechanism, and the specific shape is consistent with the bending part on the bracket 4. The receiving mechanism 3 can carry and transmit the printing medium. The bracket is provided with a bending part 1 bent along the longitudinal direction, and the transmission mechanism moves along the bending part 1, so that the printing medium is transmitted in the transverse and longitudinal directions, so that the transmission device can make the path of the printing medium longer and the movement time longer under the same floor space or length of the transmission device (this length can be interpreted as the distance between the feeding end and the output end of the transmission device), so that the movement time of the printing medium between two adjacent workstations meets the required time; that is, the transmission path of the printing medium is lengthened, and the floor space or length of the entire transmission device is reduced (when the bending part 1 is bent along the longitudinal direction, the floor space of the transmission device is reduced; if the bending part is bent along the transverse direction, the length of the transmission device is reduced); thereby reducing the volume of the entire transmission device, making the structure of the entire transmission device more compact, solving the technical problem of large volume in the existing printing equipment, and having the advantages of compact structure and small floor space.

[0033] In addition to providing the support 4 to form the bending portion 1, the bending portion 1 can be formed by winding the transmission mechanism itself (such as Figure 4 As shown in FIG. 1 , the transmission mechanism rotates along the outer contour of the bending portion 1. The bending can be performed not only in the longitudinal direction but also in the transverse direction (horizontal direction).

[0034] Preferably, combined Figure 1 and Figure 2 As shown, the transmission mechanism includes: a driving component and a transmission member 2, the output end of the driving component is transmission-connected to the transmission member 2, the receiving mechanism 3 is connected to the transmission member 2, and the driving component drives the transmission member 2 to drive the receiving mechanism 3 to move.

[0035] In this embodiment, the transmission path of the transmission member 2 is similar to the profile of the bracket 4; the transmission member 2 is wound around to form a bending portion 1 (see Figure 4), after the conveying member 2 is bent along the longitudinal direction, it is bent 90° along the transverse direction, then bent 90° downward along the longitudinal direction, and then bent 90° transversely, so as to form a bending portion 1; in this embodiment, four bending portions 1 are preferably provided to lengthen the transmission path of the printing medium, thereby ensuring that the printing medium has sufficient reaction time between the two workstations. The conveying member 2 is configured as a chain, and the receiving mechanism is configured as a plate-shaped structure, so that the printing medium is prevented from being on the receiving mechanism. The driving assembly includes a motor and a sprocket, and the output end of the motor is connected in a transmission manner. The sprocket meshes with the chain, and the motor drives the sprocket to drive the chain to rotate, thereby driving the receiving mechanism to move; a driven sprocket 5 is provided at the corner of the conveying member 2 corresponding to the bending portion 1; the driven sprocket 5 is connected to the rotation, and the driven sprocket 5 can rotate around its own axis. The motor drives the sprocket to drive the chain to rotate, thereby driving each driven sprocket 5 to rotate, so as to realize the transmission of the printing medium along the bending portion 1. In this embodiment, any driven sprocket 5 can be used as a sprocket to connect the motor, and the driving motor can make the entire conveying member rotate.

[0036] Preferably, combined Figure 2-Figure 4 The path along which the conveying member 2 transmits the carrying mechanism 3 around the bending portion 1 forms a closed loop.

[0037] In this embodiment, the conveyor 2 is wound around itself to form four bending parts 1. After the last bending part 1 is bent downward, it is bent along the direction of the first bending part 1 and connected to the starting point of the first bending part 1 to form a closed ring conveyor 2; the conveyor 2 transmits the receiving mechanism along the contour of the bending part 1, and returns to the starting position after completing all the bending parts 1, so that the transmission path of the receiving mechanism forms a loop. A feeding position can be set at one end of the conveyor 2, and a unloading position can be set at the other end of the conveyor 2, and the unloading position is correspondingly set at the last bending part 1; the printing medium enters the receiving mechanism at the feeding position, and the conveying track transmits the printing medium along the bending part 1. After unloading at the unloading position, the empty receiving mechanism is transmitted back to the loading position for the next round of cache transmission.

[0038] Preferably, two conveying members 2 are provided, and the two conveying members 2 are respectively connected to the opposite sides of the receiving mechanism 3 .

[0039] In this embodiment, the conveying member 2 is respectively arranged on both sides of the conveying direction of the entire printing medium, so that the entire receiving structure is smoothly conveyed on the conveying member 2 .

[0040] Preferably, the two conveying members 2 are arranged around the bending portion 1 and are staggered.

[0041] In this embodiment, the specific Figure 3As shown, each conveying member 2 corresponds to a bracket 4, each bracket 4 is provided with a plurality of bending portions, the two brackets 4 are staggered, and the bending portions on the two brackets 4 are staggered; this facilitates the formation of a loading portion and a unloading portion on the entire transmission device, so as to facilitate the transmission of the printing medium into the transmission device, or facilitate the unloading of the printing medium.

[0042] Preferably, combined Figure 1 and Figure 2 For the same receiving mechanism 3 , one of the diagonal corners of the receiving mechanism 3 is connected to a transmission member 2 , and the other diagonal corner of the receiving mechanism 3 is connected to another transmission member 2 .

[0043] In this embodiment, one of the conveying members 2 is connected to a vertex a of the receiving mechanism 3, and the other track is connected to a vertex b of the receiving mechanism 3. Vertex a and vertex b are a set of diagonal angles of the receiving mechanism 3. In this way, when the receiving mechanism 3 is located at the first bending portion 1 or the last bending portion 1 of the conveying member 2, the receiving mechanism 3 has two adjacent sides that are not blocked by the conveying member 2. One of the two sides can be selected to set the corresponding feeding position and unloading position. Therefore, the longer side can be selected to be set as the feeding position, and the side corresponding to the feeding position can be set as the unloading position, which is convenient for loading and unloading. The two conveying members 2 have the same shape, and the two conveying members 2 are parallel to each other; such as Figure 3 As shown, the printing medium enters the receiving mechanism 3 from the direction of arrow c, and the printing medium enters the receiving mechanism 3 along the bending portion 1 (see Figure 4 ) after transmission, it reaches the last bending section 1 (see Figure 4 ) is finally transmitted downward. At the unloading position, the discharging mechanism (not shown in the figure) discharges the printing medium along the direction of arrow d, and the empty receiving mechanism 3 returns to the loading position along the transmission mechanism to continue the next round of cache transmission.

[0044] Preferably, combined Figure 1 , Figure 2 as well as Figure 5 and Figure 6 The receiving mechanism 3 is rotatably connected to the conveying member 2.

[0045] In this embodiment, the receiving mechanism 3 is rotationally connected to the conveying member 2. When the transmission trajectory of the conveying member 2 turns, due to the relative rotational connection between the receiving mechanism 3 and the conveying member 2, the receiving mechanism 3 is relatively fixed, and the conveying member 2 rotates, so that the direction of the receiving mechanism 3 remains unchanged, and the receiving mechanism 3 can always keep carrying the printing medium, which is convenient for transmitting the printing medium.

[0046] Preferably, combined Figure 1 and Figure 2The transmission member 2 is provided with a connecting member 21, and the receiving mechanism 3 is provided with a rotating assembly corresponding to the connecting member 21, and the receiving mechanism 3 is connected to the connecting member 21 through the rotating assembly.

[0047] In this embodiment, the connecting member 21 is arranged on the side of the conveying member 2, and combined with Figure 5 and Figure 6 The rotating assembly includes a rotating shaft 31 and a clamping member 32. The central axis of the rotating shaft 31 is connected to the receiving mechanism and can rotate around its own central axis. The rotating shaft 31 is rotatably connected to the clamping member 32. Two protrusions 211 are provided on the connecting member, and a clamping groove 321 is correspondingly provided on the clamping member 32. The protrusion 211 is clamped in the clamping groove 321 to make the connecting member 21 and the clamping member 32 connected to the rotating shaft 31 rotate, so that the conveying member 2 and the receiving mechanism rotate relatively.

[0048] Preferably, combined Figure 5 and Figure 6 The receiving mechanism 3 includes: a receiving portion 34 , a pressing portion 33 and an adjusting component 35 ; the receiving portion 34 and the pressing portion 33 are connected via the adjusting component 35 , and the adjusting component 35 is used to adjust the relative position between the pressing portion 33 and the receiving portion 34 .

[0049] In this embodiment, the pressing part 33 is arranged on the upper end surface of the receiving part 34. The receiving part 34 is a plate-like structure, and the adjusting component 35 includes a lifting part, which is arranged between the receiving part 34 and the pressing part 33. When a certain external force is applied to the lifting part, the pressing part 33 is lifted up, and the pressing part 33 is separated from the upper end surface of the receiving part 34, and then opened to facilitate the discharge of the printing medium into the receiving mechanism 3, or the discharge of the printing medium in the printing medium; when the external force applied to the lifting part is cancelled, the pressing part 33 falls due to its own gravity, and then the pressing part 33 and the receiving part 34 are closed again, so as to press the printing medium on the receiving part 34, and prevent the printing medium from being deflected by other external forces during transportation.

[0050] The receiving mechanism 3 includes: a receiving portion 34 for carrying the printing medium; a pressing portion 33, a receiving space for accommodating the printing medium is formed between the pressing portion 33 and the receiving portion 34, and the pressing portion 33 cooperates with the receiving portion 34 to press the printing medium.

[0051] The transmission mechanism includes: a driving component and a transmission member 2, the output end of the driving component is transmission-connected to the transmission member 2, the receiving mechanism 3 is connected to the transmission member 2, and the driving component drives the transmission member 2 to drive the receiving mechanism 3 to move.

[0052] In this embodiment, if Figure 7As shown, the receiving portion 34 is L-shaped from the side view, and the pressing portion 33 is L-shaped from the side view. The receiving portion 34 and the pressing portion 33 cooperate with each other, and the right angles of the two cooperate with each other. The pressing portion 33 is arranged on the upper end surface of the receiving portion 34. The receiving portion 34 is a plate-like structure. Since the pressing portion 33 is arranged to press the printing medium on the receiving portion 34, the printing medium is prevented from being deflected by other external forces during transportation, which solves the technical problem that the printing medium is easily displaced when the bearing device in the existing transmission device carries a lighter printing medium.

[0053] Preferably, if Figure 4 As shown, the distance between the pressing portion 33 and the receiving portion 34 is adjustable.

[0054] In this embodiment, the distance between the pressing part 33 and the receiving part 34 is set to be adjustable, and the distance between the pressing part 33 and the receiving part 34 can be adjusted according to the thickness of the printing medium, so that the space between the pressing part 33 and the receiving part 34 can adapt to printing media of different thicknesses. In addition, the distance between the pressing part 33 and the receiving part 34 is set to be adjustable, and the distance between the pressing part 33 and the receiving part 34 is adjusted according to the time when the printing medium enters between the receiving part 34 and the pressing part 33, that is, the time of feeding and discharging, so as to facilitate the printing medium to enter the space between the receiving part 34 and the pressing part 33, or to facilitate the printing medium to be discharged from between the receiving part 34 and the pressing part 33. Specifically, the pressing part 33 can be set on the upper surface of the receiving part 34, and the adjustment component 35 is set to adjust the distance between the pressing part 33 and the receiving part 34.

[0055] Preferably, if Figure 5 As shown, the adjusting component 35 , the receiving portion 34 and the pressing portion 33 are connected via the adjusting component 35 , and the adjusting component 35 is used to adjust the distance between the pressing portion 33 and the receiving portion 34 .

[0056] In this embodiment, an adjustment component 35 is provided to adjust the distance between the pressing part 33 and the receiving part 34, so that the distance between the pressing part 33 and the receiving part 34 can be adjusted according to demand. For example, before the printing medium enters the receiving part 34, the distance between the pressing part 33 and the receiving part 34 is increased, thereby facilitating the printing medium to enter the receiving part 34. After the printing medium enters the receiving part 34, the distance between the pressing part 33 and the receiving part 34 is shortened, so that the pressing part 33 presses the printing medium; when the printing medium needs to be transported out of the receiving part 34, the distance between the pressing part 33 and the receiving part 34 is increased, thereby facilitating the printing medium to be transported to the receiving part 34.

[0057] Preferably, if Figure 7 As shown, the adjustment component 35 (see Figure 5) includes: a lifting portion 351, the lifting portion 351 is used to lift the pressing portion 33 to adjust the distance between the pressing portion 33 and the receiving portion 34.

[0058] In this embodiment, the lifting portion 351 is provided to facilitate lifting the pressing portion 33, to facilitate lifting the pressing portion 33, and to facilitate adjusting the distance between the receiving portion 34 and the pressing portion 33. One end of the lifting portion 351 is in contact with or connected to the pressing portion 33, and the other end extends away from the pressing portion 33, so as to facilitate applying force to the lifting portion 351. In other embodiments, the pressing portion 33 and the receiving portion 34 are rotatably connected, and the lifting portion 351 is provided at one end of the pressing portion 33 away from the receiving portion 34, and an external force is applied to the lifting portion 351, so that one end of the lifting portion 351 toward the receiving portion 34 follows the rotation of the lifting portion 351 and opens, thereby adjusting the distance between the pressing portion 33 and the receiving portion 34.

[0059] Preferably, the lifting portion 351 is rotatably connected to the receiving portion 34 , one end of the lifting portion 351 abuts against the pressing portion 33 , and the other end of the lifting portion 351 extends away from the receiving portion 34 .

[0060] In this embodiment, the lifting part 351 is prismatic in side view, the middle part of the lifting part 351 is rotatably connected with the receiving part 34 through a pin, and the receiving part 34 is provided with a rotation space for the lifting part 351 to rotate corresponding to the lifting part 351; when the lifting part 351 is not subjected to external force, the end of the lifting part 351 close to the pressing part 33 just abuts against the pressing part 33, and at this time, the pressing part 33 is pressed against the printing medium by its own weight to press the printing medium. When external force is applied to the end of the lifting part 351 away from the pressing part 33, the end close to the pressing part 33 rotates to lift the pressing part 33 away from the receiving part 34, so that the printing medium enters between the receiving part 34 and the pressing part 33, or is discharged from between the receiving part 34 and the pressing part 33. In other embodiments, the lifting portion 351 may be connected to the pressing portion 33, and the lifting portion 351 extends away from the pressing portion 33, with one end of the extension serving as a force application site. When force is applied to the lifting portion 351, the distance from the pressing portion 33 to the upper surface of the receiving portion 34 increases, thereby facilitating the entry of the printing medium between the receiving portion 34 and the pressing portion 33. When the external force applied to the lifting portion 351 is removed, the pressing portion 33 falls downward under the influence of its own gravity and returns to the upper end surface of the receiving portion 34.

[0061] Preferably, combined Figure 7 as well as Figure 8 , adjusting component 35 (see Figure 5 ) includes: a lifting portion 352; the lifting portion 352 is penetrated by the receiving portion 34, one end of the lifting portion 352 is connected to the clamping portion 33, and the other end of the lifting portion 352 extends away from the receiving portion 34.

[0062] In this embodiment, the receiving portion 34 is provided with a through hole for the lifting portion 352 to pass through, and the lifting portion 352 can slide in the through hole. On the one hand, when the lifting portion 351 lifts the pressing portion 33, the lifting portion 352 slides in the through hole and plays a guiding role. When the pressing portion 33 falls due to its own gravity and returns to the upper end surface, the lifting portion 352 plays a guiding role, so that the pressing portion 33 is accurately reset. On the other hand, a certain external force is applied to the lifting portion 352 to lift the pressing portion 33, which is convenient for lifting the pressing portion 33. The lifting portion 351 and the lifting portion 352 are provided at the same time, and the force acting on the pressing portion 33 can be selected according to the usage scenario, so as to choose whether to act on the lifting portion 352 or the lifting portion 351, so as to facilitate opening the pressing portion 33. The design is ingenious. For example, when it is more convenient to apply external force to the bottom of the receiving part 34, it is chosen to apply the external force to the lifting part 352 to facilitate opening the clamping part 33; when it is more convenient to apply external force to the outside of the receiving part 34, it is chosen to apply the external force to the lifting part 351 to facilitate lifting the clamping part 33. The structure is simple and the design is ingenious.

[0063] Preferably, if Figure 7 As shown, the adjustment assembly 35 further includes: an abutment portion 353 ; the abutment portion 353 is disposed at one end of the lifting portion 352 away from the pressing portion 33 , and is used for abutting against the receiving portion 34 .

[0064] In this embodiment, the diameter of the abutment portion 353 is larger than the inner diameter of the through hole. When the lifting portion 352 moves upward, the abutment portion 353 abuts against the receiving portion 34 after moving to a certain extent, thereby preventing excessive external force from being applied to the lifting portion 352, causing the lifting portion 352 to move out of the through hole and be difficult to reset.

[0065] Preferably, if Figure 7 As shown, the adjustment component 35 (see Figure 5 ) also includes a reset member 354; the reset member 354 provides a reset force for the clamping portion 33 to reset the clamping portion 33.

[0066] In this embodiment, the reset member 354 is configured as a spring, which is sleeved on the outer side of the lifting portion 352 and located between the abutting portion 353 and the receiving portion 34. When an external force is applied to the lifting portion 352, the lifting portion 352 lifts the clamping portion 33 and the elastic member is compressed. When the external force applied to the lifting portion 352 is withdrawn, the elastic member generates an elastic force when it returns to its original state. At this time, the elastic force acts on the abutting portion 353, thereby causing the abutting portion 353 to move downward, thereby driving the lifting portion 352 and the clamping portion 33 to quickly reset. In other embodiments, the reset member 354 can also be configured as a tension spring, which is arranged between the receiving portion 34 and the clamping portion 33, with one end of the tension spring connected to the receiving portion 34, and the other end connected to the clamping portion 33. When the clamping portion 33 is lifted up, the tension spring is stretched, and after the external force of the rear lifting portion 352 is removed, the tension spring returns to its original state and generates a tension force, pulling the clamping portion 33 back to its original position, thereby facilitating the reset of the clamping portion 33.

[0067] Preferably, the cache transmission device further comprises: a bracket 4 (see Figure 1 ) and a force-applying portion; the bracket 4 is used to install the transmission mechanism, and the receiving portion 34 is connected to the transmission mechanism; the force-applying portion is arranged on the bracket 4, and when the receiving portion 34 moves relative to the force-applying portion as the transmission mechanism moves, the force-applying portion abuts against the adjusting component 35 and applies an external force to the adjusting component 35 to adjust the distance between the clamping portion 33 and the receiving portion 34.

[0068] In this embodiment, an external force is applied to the adjustment component 35 by means of the relative movement between the receiving portion 34 and the force-applying portion, so as to adjust the distance between the clamping portion 33 and the receiving portion 34; when the receiving portion 34 moves toward the force-applying portion and the force-applying portion contacts the adjustment component 35, the adjustment component 35 continues to move, and the force-applying portion is fixed. At this time, the adjustment component 35 is subjected to the relative force, thereby opening the clamping portion 33; the receiving portion 34 continues to move, and the abutment relationship between the adjustment component 35 and the force-applying portion is destroyed, that is, the external force applied to the adjustment component 35 by the force-applying portion is cancelled, and the clamping portion 33 falls back to the surface of the receiving portion 34 due to its own gravity, thereby realizing the closing of the clamping portion 33; with the relative movement relationship between the bracket 4 and the conveying member 2, the automatic opening and automatic closing of the clamping portion 33 can be realized.

[0072] In this embodiment, the discharge end (reference Figure 3 The second force-applying part 7 includes a fixed part 71 and a rotating part 72. The fixed part 71 is fixed on the bracket 4 (the position of the second force-applying part installed on the bracket is not shown in the figure. Those skilled in the art can set the position of the discharge end and the feed end according to their needs. For reference, Figure 1 as well as Figure 3, confirm the installation position, no further details are given here); the rotating portion 72 is rotatably connected to the fixed portion 71, and the rotating portion 72 and the fixed portion 71 are both configured as plate-like structures; three groups of lifting portions 352 are provided, which are evenly distributed in the length direction of the pressing portion 33; the rotating portion 72 applies external force to the three groups of lifting portions 352 at the same time; and a return spring is provided between the rotating portion 72 and the fixed portion 71; when unloading, the receiving portion 34 moves downward (the receiving portion 34 moves downward in the direction of the arrow Y in the figure), and the lifting portion 352 acts on the rotating portion 72, and the lifting portion 352 is subjected to the reaction force to press the pressing portion 33 The part 33 is lifted up to open the clamping part 33. At this time, the printing medium can be discharged from the receiving part 34; at the same time, the receiving part 34 continues to move downward, so that the rotating part 72 is forced to rotate (rotate in the direction of the arrow m in the figure) to provide space for the receiving part 34 to pass through; when the receiving part 34 passes through, the clamping part 33 is reset due to the influence of gravity; the reset spring between the fixed part 71 and the receiving part 34 resets the rotating part 72; continue the next round of opening and closing the clamping part 33; preferably, the rotating part 72 is set to an elastic material to facilitate the bending of the rotating part 72, thereby providing space for the receiving part 34 to pass through.
