Description

Technical Field

[0001] This utility model belongs to the field of printing technology, specifically relating to a paper receiving mechanism and a printing press. Background Technology

[0002] A printing press is a device used to print text, images, and other graphics. There are many types of printing presses, ranging from small office printers to large industrial printing presses.

[0003] Currently, printing presses often collect printed paper in a way that results in the paper being scattered and piled up haphazardly, requiring manual sorting. In particular, the large ink volume commonly found in current printing presses leads to uneven paper collection, making manual sorting time-consuming and labor-intensive. Furthermore, paper with high ink volume becomes damp and deformed, making it impossible to collect properly, causing great inconvenience to users. Utility Model Content

[0004] This utility model provides a paper receiving mechanism and a printer, which aims to make the printed papers stacked in a staggered manner, thus solving the inconvenience caused to users by manually arranging the papers.

[0005] Firstly, to achieve the above objectives, the technical solution adopted by this utility model is as follows: a paper receiving mechanism is provided, comprising: a frame, side alignment boards, a swing drive assembly, a paper alignment drive assembly, and a paper receiving platform. The frame is mounted on the overall frame of a printing press; the side alignment boards are divided into two groups and installed on the left and right sides of the frame; the swing drive assembly is mounted on the frame to drive the side alignment boards to swing up and down; the paper alignment drive assembly is divided into two groups and installed on the left and right sides of the frame, respectively driving the side alignment boards on the same side to move back and forth left and right; the paper receiving platform is disposed below the side alignment boards. When the swing drive assembly drives the side alignment cardboard to swing up and down, one side of the side alignment cardboard presses against the stack of paper on the receiving platform and forms a paper-aligning and blocking structure. The other side of the side alignment cardboard moves back and forth under the drive of the paper-aligning drive assembly on the same side, and conveys the paper to the receiving platform from the side. The side alignment cardboards on both sides alternately block and align the paper, so that the stack of paper on the receiving platform is staggered according to the number of papers.

[0006] In conjunction with the first aspect, in one feasible manner, the swing drive assembly includes a swing drive motor mounted on the side of the frame, an eccentric transmission structure mounted on the main shaft of the swing drive motor, and a first coaxial structure rotatably mounted on the frame, wherein the side-aligning cardboards on both sides are mounted on the first coaxial structure. The swing drive motor drives the two side-aligning paperboards connected to the first coaxial to swing up and down through the eccentric transmission structure. While the side-aligning paperboard on one side blocks the paper, the side-aligning paperboard on the other side aligns with the paper. The paper alignment drive assembly drives the side alignment cardboard to reciprocate along the first coaxial direction to move the side alignment paper.

[0007] In conjunction with the first aspect, in one feasible manner, two side-aligning cardboards are arranged one in front of the other on the same side of the frame. The two side-aligning cardboards located in front are respectively mounted on two first single shafts, which are rotatably mounted on the frame. The two side-aligning cardboards located behind are connected to the two ends of a first coaxial axis. The first coaxial axis and the first single shaft are connected by a linkage transmission structure. The linkage transmission structure is hinged to the eccentric transmission structure.

[0008] In conjunction with the first aspect, in one feasible manner, the eccentric transmission structure includes an eccentric rod mounted on the main shaft of the swing drive motor and a transmission rod hinged to the eccentric rod; The linkage transmission structure includes a rear swing arm, a connecting rod, and a front swing arm that are hinged in sequence. One end of the rear swing arm is hinged to the transmission rod, and the other end of the rear swing arm is connected to the first coaxial rod. The front swing arm is connected to the first single shaft. The power of the swing drive motor drives the first coaxial swing through the eccentric rod, the transmission rod, and the rear swing rod, and drives the first single-axis swing through the rear swing rod, the connecting rod, and the front swing rod.

[0009] In conjunction with the first aspect, in one feasible manner, the swing drive assembly further includes a follower lever mounted on the first coaxial axis and the first single axis. When the swing drive motor drives the first coaxial axis and the first single axis to swing counterclockwise, the synchronously swinging follower lever swings backward, causing each of the side-aligning cardboards mounted on the first coaxial axis and the first single axis to swing upward and leave the paper stack on the paper receiving platform. When the swing drive motor drives the first coaxial and the first single shaft to swing clockwise, the follower lever swings forward synchronously to release the external force on the side-aligned cardboard, and the side-aligned cardboard swings downward under its own weight. The upper end of the side-aligning paperboard is provided with an upwardly protruding force-receiving part; the follower lever applies pressure to the force-receiving part, causing the side-aligning paperboard to swing upward; the lower end of the side-aligning paperboard has a forward-extending arc-shaped paper-stopping part. In conjunction with the first aspect, in one feasible manner, the paper alignment drive assembly includes a paper alignment drive motor, a drive shaft connected to the main shaft of the paper alignment drive motor, and a belt drive structure mounted at the front and rear ends of the drive shaft. The belt drive structure is located above the front and rear side alignment paperboards respectively. The belt drive structure is provided with sliding blocks between the first coaxial axis and the first single axis respectively. The lower end of the sliding block is slidably fitted on the first coaxial axis and the first single axis respectively. The paper alignment drive motor drives the corresponding side alignment paperboard to move back and forth left and right through the drive shaft, the belt drive structure and the sliding block.

[0010] In conjunction with the first aspect, in one feasible manner, the lower end of the sliding block has two claws, and the upper end of the side-aligning cardboard is positioned between the two claws to move left and right synchronously with the sliding block.

[0011] In conjunction with the first aspect, in one feasible manner, the upper ends of the sliding blocks located on both front sides are respectively fitted onto a second single shaft, which is mounted on the frame; The upper ends of the sliding blocks located on both rear sides are all fitted onto the second coaxial axis, and the two ends of the second coaxial axis are mounted on the frame; The second single axis is parallel to the first single axis, and the second coaxial axis is parallel to the first coaxial axis, forming the anti-rotation limiting structure of the sliding block.

[0012] In conjunction with the first aspect, in one feasible manner, the paper receiving mechanism further includes a front stop plate mounted at the front end of the machine frame, the front stop plate stopping the front side of the paper.

[0013] In conjunction with the first aspect, in one feasible embodiment, the paper receiving mechanism further includes a rear paper pushing structure mounted on the machine frame and symmetrically arranged on both sides, the rear paper pushing structure being located behind the paper alignment drive assembly; the rear paper pushing structure includes a rear paper pushing plate and a paper pushing slide mounted on the machine frame; the rear paper pushing plate is mounted on the paper pushing slider of the paper pushing slide, and when the front end of the conveyed paper passes the rear paper pushing plate, the paper pushing slide pushes the rear paper pushing plate to contact the rear end of the paper, thereby assisting in the forward conveying of the paper.

[0014] Secondly, this utility model embodiment also provides a printing machine, including the aforementioned paper receiving mechanism.

[0015] Compared with the prior art, the paper receiving mechanism and printing machine provided by this utility model have the following advantages: When the swing drive component drives the side alignment cardboard to swing downward, the side alignment cardboard on one side presses against the stack of paper on the receiving platform and forms a paper-aligning and blocking structure. The side alignment cardboard on the other side moves back and forth under the drive of the same side alignment drive component, conveying the paper to the receiving platform from the side. The side alignment cardboards on both sides alternately block and align the paper, so that the stack of paper on the receiving platform is staggered according to the number of papers. The printed paper is neatly stacked into multiple stacks, which can effectively solve the problem of paper being randomly stacked and requiring manual alignment when receiving paper in existing printing machines. Moreover, when printing large batches of documents, the gaps between adjacent stacks of paper allow for separate stacking of paper, facilitating subsequent binding, storage, and other operations. This further improves the convenience and efficiency of the entire printing process, reduces the time users spend sorting and retrieving paper, and greatly enhances the user's convenience.

[0018] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] Unless otherwise expressly defined, the use of terms such as "first," "second," or "third" in the claims, description, and drawings of this utility model is for distinguishing different objects and not for describing a specific order.

[0020] For mass-produced paper, after continuous printing on a printing press, the stack of paper may be tens of centimeters high. When manually handling the stacked paper after printing, it is not only easy to damage the paper, but also difficult to handle it in layers. Especially when repeatedly printing books or documents in batches, it is necessary to manually sort and classify the printed books or documents, which causes great inconvenience to the subsequent binding.

[0021] Please refer to sections 1 to 2. Figure 13 The paper receiving mechanism provided by this utility model will now be described. The paper receiving mechanism includes: a frame 160, side-aligning plates 130, a swing drive assembly 110, a paper-aligning drive assembly 120, and a paper receiving platform 300. The frame 160 is mounted on the overall frame 200 of the printing press. The side-aligning plates 130 are divided into two groups and installed on the left and right sides of the frame 160. The swing drive assembly 110 is mounted on the frame 160 to drive the side-aligning plates 130 to swing up and down. The paper-aligning drive assembly 120 is divided into two groups and installed on the left and right sides of the frame 160, respectively driving the side-aligning plates 130 on the same side to swing left and right. The paper receiving platform 300 is positioned below the side-aligning cardboard 130. When the swing drive assembly 110 drives the side-aligning cardboard 130 to swing downwards, one side of the side-aligning cardboard 130 presses against the stack of paper on the receiving platform 300, forming a paper-aligning and paper-blocking structure. The other side of the side-aligning cardboard 130 moves back and forth under the drive of the same side-aligning drive assembly 120, conveying the paper to the receiving platform 300 from the side. The side-aligning cardboards 130 on both sides alternately block and align the paper, so that the stack of paper on the receiving platform 300 is staggered according to the number of papers.

[0022] Compared with the prior art, the paper receiving mechanism 100 and printing press provided by this utility model have the following advantages: When the swing drive assembly 110 drives the side-aligning cardboard 130 to swing downward, one side of the side-aligning cardboard 130 presses against the stack of paper on the receiving platform 300, forming a paper-aligning and paper-stopping structure. The other side of the side-aligning cardboard 130 moves back and forth under the drive of the same side-aligning drive assembly 120, conveying the paper to the receiving platform 300 from the side. The side-aligning cardboard 130 on both sides alternately stops and aligns the paper, making the paper evenly conveyed from the side to the receiving platform 300. The paper stacks on the paper receiving platform 300 are staggered according to the number of papers, and the printed papers are neatly stacked into multiple layers. This effectively solves the problem of paper being randomly stacked and requiring manual sorting when receiving paper in existing printing presses. Moreover, when printing large batches of documents, the gaps between adjacent layers of paper stacks allow for separate handling of the paper, facilitating subsequent binding, storage, and other operations. This further enhances the convenience and efficiency of the entire printing process, reduces the time users spend sorting and stacking, and greatly improves user convenience.

[0023] Therefore, for printed paper that is damp and deformed due to a large amount of ink, the side-aligning cardboard on both sides can be used to make the printed paper side-aligned and flat, eliminating the need for manual finishing.

[0024] In actual operation, the side alignment cardboard 130s on both sides alternately perform paper-blocking and side-aligning actions. Specifically, when the left side alignment cardboard 130 is pressing against the lower stack of paper and is in a paper-blocking state, the right side alignment cardboard 130, driven by the right side alignment drive component 120, aligns the paper to the left. When the stack of paper reaches a preset height, the swing drive component 110 reverses its movement, causing the side alignment cardboard 130s on both sides to swing upwards away from the paper. The right side alignment cardboard 130, driven by the right side alignment drive component 120, moves to the left and presses against the stack of paper to become a paper-blocking structure. At the same time, the left side alignment cardboard 130, driven by the left side alignment drive component 120, begins to perform a side-aligning action. This cycle repeats, and the stacks of paper on the receiving platform 300 are gradually staggered and stacked according to the preset height, forming a staggered stack of paper 400. See below. Figure 13 As shown.

[0025] Based on the number of pages in the book, the control system sets the number of sheets of paper in each stack, so that the side alignment cardboard 130 on both sides alternately blocks and aligns the paper, so that each set of books is automatically divided into a stack. When picking up and binding later, a set of books can be easily picked up and bound from the gap between the two stacks of paper, without the need for manual separation, which greatly improves the convenience of the user.

[0026] Based on the design concept of this application, different numbers of papers can be stacked into a single stack through a control system, and it is not limited to staggered stacking of the same number of papers.

[0027] The above technical solution designs a basic structure of alternating staggered stacking of paper stacks. The side-aligned paperboards 130 on the left and right sides of this application can swing upwards and reset downwards simultaneously, which is achieved by a set of drives. In other embodiments, the side-aligned paperboards 130 on the left and right sides can also be achieved by different drives.

[0028] In some embodiments, see Figures 5 to 13 The swing drive assembly 110 includes a swing drive motor 111 mounted on the side of the frame 160, an eccentric transmission structure mounted on the main shaft of the swing drive motor 111, and a first coaxial 119 rotatably mounted on the frame 160. The side alignment paperboards 130 on both sides are mounted on the first coaxial 119. The swing drive motor 111 drives the two side alignment paperboards 130 connected to the first coaxial 119 to swing up and down through the eccentric transmission structure. While one side alignment paperboard 130 blocks the paper, the other side alignment paperboard 130 aligns the paper. The paper alignment drive assembly 120 drives the side alignment paperboards 130 to reciprocate along the first coaxial 119 to align the paper.

[0029] The main shaft of the swing drive motor 111 rotates clockwise and counterclockwise, driving the first coaxial 119 to rotate clockwise and counterclockwise, thereby realizing the up-and-down swing of the side-aligned cardboard 130.

[0030] In some embodiments, see Figures 5 to 12 Two side-aligning plates 130 are arranged one in front of the other on the same side of the frame 160. The two side-aligning plates 130 located in front are respectively mounted on two first single shafts 117, which are rotatably mounted on the frame 160. The two side-aligning plates 130 located behind are connected to the two ends of a first coaxial 119. The first coaxial 119 and the first single shaft 117 are connected by a connecting rod 115 transmission structure. The connecting rod 115 transmission structure is hinged to the eccentric transmission structure.

[0031] Two side-aligning cardboard plates 130 are set on the same side, one in front and one behind, so that the sides of the paper can be aligned simultaneously and synchronously in the front and back directions. This can avoid the phenomenon of unevenness caused by the paper shifting during side alignment. When used as a paper stop structure, the two side-aligning cardboard plates 130 on the same side form two-point positioning stops for the paper, which can also prevent the paper from shifting and becoming uneven in the front and back.

[0032] During the side-aligning action, the two side-aligning cardboard plates 130 move towards the side of the paper simultaneously, acting on the front and rear ends of the paper's side respectively, achieving synchronous alignment in the front-to-back direction. This dual-point synchronous force application method avoids the skewing problem that may occur with a single alignment point, where one end of the paper is aligned while the other end is offset, allowing the paper's side to form a complete flat surface from the front to the rear, improving the neatness of the paper stack. When the two side-aligning cardboard plates 130 press against the paper stack simultaneously, they form a stable two-point support paper-stopping structure, which, compared to a single-point paper-stopping structure, can more comprehensively restrict the displacement of the front and rear ends of the paper, further ensuring the regularity of the paper stack.

[0033] This layout of double-sided paperboard 130 ensures uniform force and alignment across all sides during side alignment and provides all-around displacement restriction during paper blocking. This dual-action approach completely solves problems such as paper shifting and stacking skew that can occur with traditional single-sided paperboard 130 or single-point paper blocking. Especially for large-size paper, thin and brittle paper, or high-speed printing scenarios, the dual-point collaborative design significantly improves the stability of paper alignment. This results in clear interlayer gaps in the subsequently formed staggered stacks of paper, and a substantial improvement in the front-to-back and left-to-right regularity of each stack. This provides a more precise foundation for subsequent processes such as stacking, binding, and cutting, further expanding the adaptability of the paper receiving mechanism 100 to different paper types and printing conditions.

[0034] In some embodiments, see Figures 7 to 10 The eccentric transmission structure includes an eccentric rod 112 mounted on the main shaft of the swing drive motor 111 and a transmission rod 113 hinged to the eccentric rod 112; the connecting rod 115 transmission structure includes a rear swing rod 114, a connecting rod 115 and a front swing rod 116 hinged in sequence, one end of the rear swing rod 114 is hinged to the transmission rod 113, and the other end of the rear swing rod 114 is connected to the first coaxial 119; the front swing rod 116 is connected to the first single shaft 117; the power of the swing drive motor 111 drives the first coaxial 119 to swing through the eccentric rod 112, the transmission rod 113 and the rear swing rod 114, and drives the first single shaft 117 to swing through the rear swing rod 114, the connecting rod 115 and the front swing rod 116.

[0035] The combined design of eccentric drive and connecting rod 115 eliminates the need for complex gearboxes, reduction mechanisms, or electronic synchronization modules. Synchronous movement of the front and rear cardboard aligners 130 is achieved solely through the hinged linkage of the mechanical structure, significantly simplifying the equipment's transmission system and allowing for a more compact internal layout within the frame 160, thus reducing the space occupied by the equipment. Furthermore, the transmission structure primarily consists of standardized rod-shaped and shaft-like parts, resulting in a simple structure and convenient assembly and disassembly. Subsequent maintenance only requires checking the lubrication of the hinges and the wear of the parts, eliminating the need for specialized repair tools or complex debugging procedures, thereby reducing the difficulty of equipment maintenance and operating costs.

[0036] In the above technical solution, the eccentric rod 112 can also be an eccentric wheel or a cam. The main shaft of the swing drive motor 111 rotates forward and backward, driving the eccentric rod 112 to swing forward and backward. This power is transmitted to the rear swing rod 114 through the transmission rod 113. After passing through the rear swing rod 114, this power is divided into two paths. One path is transmitted to the first coaxial 119, driving the first coaxial 119 to swing. The other path is transmitted to the first single shaft 117 through the connecting rod 115 and the front swing rod, driving the first single shaft 117 to swing forward and backward. The four side-aligned cardboard plates 130 share a set of swing drive motors 111 to achieve synchronous swinging action.

[0037] Synchronized movements result in more even force distribution on the front and back ends of the paper's sides, leading to more precise alignment. It also makes the formation of interlayer gaps more regular, providing a more reliable guarantee for subsequent processes such as stacking, picking up, and binding. Especially in high-volume, high-speed printing scenarios, it can always maintain stable alignment and stacking effects.

[0038] In some embodiments, see Figures 7 to 12 The swing drive assembly 110 also includes a follower lever 118 mounted on the first coaxial 119 and the first single shaft 117. When the swing drive motor 111 drives the first coaxial 119 and the first single shaft 117 to swing counterclockwise, the follower lever 118 swings backward synchronously, causing the side alignment paperboards 130 mounted on the first coaxial 119 and the first single shaft 117 to swing upward and leave the paper stack on the paper receiving platform 300. When the swing drive motor 111 drives the first coaxial 119 and the first single shaft 117 to swing clockwise, the follower lever 118 swings forward synchronously to release the external force on the side alignment paperboards 130, and the side alignment paperboards 130 swing downward under their own weight.

[0039] The upper end of the side-aligning paperboard 130 is provided with an upwardly protruding force-receiving part 131; the follower lever 118 applies pressure to the force-receiving part 131, causing the side-aligning paperboard 130 to swing upward; the lower end of the side-aligning paperboard 130 has a forward-extending arc-shaped paper stop.

[0040] Since the side-aligning cardboard 130 in this application needs to move left and right along the first coaxial 119 or the first single axis 117 to align the paper, and also needs to be able to rotate and swing around the first coaxial 119 or the first single axis 117 to achieve the paper-blocking function, in order to achieve this purpose, this application adopts a connection relationship between the side-aligning cardboard 130 and the first coaxial 119 and the first single axis 117, which can both slide and rotate relative to each other. Then, through the follower lever 118 that swings synchronously with the first coaxial 119 and the first single axis 117, force is applied to the side-aligning cardboard 130 during swinging, causing the side-aligning cardboard 130 to swing upward, so as to adjust and alternately achieve the paper-blocking and side-aligning functions; therefore, the side-aligning cardboard 130 can move left and right along the first coaxial 119 and the first single axis 117 under the drive of the paper-aligning drive motor 121 to achieve the purpose of aligning the paper.

[0041] Since the side-aligning paperboard 130 is only connected to the first coaxial 119 or the first single axis 117 at its upper end, the side-aligning paperboard 130 is suspended with each axis as a point. Its forward-extending arc-shaped paper stop makes the center of gravity of the side-aligning paperboard 130 biased towards the front of each axis. When the follower lever 118 applies pressure backward to the force-bearing part 131 of the side-aligning paperboard 130, the lower end of the follower lever 118 swings upward. When the follower lever 118 swings forward, the pressure applied to the side-aligning paperboard 130 is eliminated. At this time, the side-aligning paperboard 130 returns to its original position under its own weight until the follower lever 118 stops swinging. The force-bearing part 131 stops swinging again due to the stop of the follower lever 118.

[0042] In the above technical solution, the follower lever 118 can be tightly fitted on the first coaxial 119 and the first single shaft 117, and locked with a locking screw to ensure synchronous rotation with the shaft.

[0043] Optionally, the structure of the side-aligning cardboard 130, which can both rotate and move left and right, can also be as follows: keyways are provided on both the first coaxial 119 and the first single axis 117, and the flat key provided on the side-aligning cardboard 130 is inserted into the keyway and has a sliding fit with the keyway. At this time, the rotation and swing of the first coaxial 119 and the first single axis 117 can drive the side-aligning cardboard 130 to swing up and down, and the side-aligning cardboard 130 can also move left and right along the first coaxial 119 and the first single axis 117 under the drive of the paper alignment drive assembly 120.

[0044] In some embodiments, see Figures 5 to 10 The paper alignment drive assembly 120 includes a paper alignment drive motor 121, a drive shaft 123 connected to the main shaft of the paper alignment drive motor 121, and a belt drive structure installed at both ends of the drive shaft 123. The belt drive structure is located above the front and rear side alignment boards 130 respectively. Sliding blocks 125 are respectively provided between the belt drive structure and the first coaxial 119 and the first single shaft 117. The lower end of the sliding block 125 is slidably fitted on the first coaxial 119 and the first single shaft 117 respectively. The paper alignment drive motor 121 drives the corresponding side alignment board 130 to move back and forth left and right through the drive shaft 123, the belt drive structure and the sliding block 125.

[0045] The above technical solution combines the characteristics of the side-aligning cardboard 130, which can both rotate and move left and right. By using a belt drive structure, it can simultaneously drive the front and rear side-aligning cardboard 130 to move left and right synchronously, thereby achieving synchronous side alignment of the paper and improving the neatness of the side alignment.

[0046] In this application, the sliding block 125 is mounted on the conveyor belt 122 of the belt drive structure via a connector. The paper-aligning drive motor 121 rotates in both directions, driving the conveyor belt 122 to rotate in both directions, thereby realizing the reciprocating movement of the sliding block 125. In the belt drive structure, the conveyor belt 122, also known as the synchronous belt, is wound around the main drive pulley 126 and the driven pulley 124. The main drive pulley 126 is directly connected to the paper-aligning drive motor 121 and is connected to the drive shaft 123. The others are all referred to as driven pulleys 124 and are not distinguished further.

[0047] Alternatively, the belt drive structure can be replaced by chain drive or gear drive.

[0048] In some embodiments, see Figures 5 to 12 The lower end of the sliding block 125 has two claws 1251, and the upper end of the side-aligning cardboard 130 is limited between the two claws 1251 so that it moves left and right synchronously with the sliding block 125. The sliding block 125 is in sliding engagement with both the first coaxial 119 and the first single-axis 117, and the two claws 1251 directly drive the side-aligning cardboard 130 to move synchronously with the sliding block 125.

[0049] In some embodiments, see Figure 9 and Figure 10 The upper ends of the sliding blocks 125 located on the front two sides are respectively fitted onto the second single shaft 128, and the second single shaft 128 is mounted on the frame 160; the upper ends of the sliding blocks 125 located on the rear two sides are each fitted onto the second coaxial 127, and the two ends of the second coaxial 127 are mounted on the frame 160; the second single shaft 128 is parallel to the first single shaft 117, and the second coaxial 127 is parallel to the first coaxial 119, forming the anti-rotation limiting structure of the sliding blocks 125.

[0050] By restricting the sliding block 125 through the second coaxial 127 above the first coaxial 119 and the second single axis 128 above the first single axis 117, it is ensured that the sliding block 125 moves in a straight line without rotating around the axis, thereby also ensuring the accuracy of the side alignment of the side-aligned cardboard 130.

[0051] It should be noted that the paper receiving mechanism 100 provided in this application is installed on the main frame 200 of the printing press, with the front facing the direction of paper transport; a vertical slide 202 of the lifting paper receiving platform 300 is installed on the main frame 200 (see...). Figure 1 When the stack of paper on the receiving platform 300 reaches a certain height, the vertical slide 202 drives the receiving platform 300 to move downward, so that the side-aligned cardboard 130 is always within the effective range of use.

[0052] See Figures 1 to 4In this application, the frame 160 mainly includes an upper support plate 162 and two side upright plates 161. At least one end of each shaft is rotatably connected to the side upright plate 161 via a bearing. The support plate 162 is connected between the two side upright plates 161 and also provides support for each shaft. For example, one end of the first single shaft 117 is rotatably connected to the side upright plate 161, and the other end is rotatably connected to a support fixed to the lower surface of the support plate 162. As for the first coaxial 119, since the first coaxial 119 is relatively long, it is also located in the middle position of the first coaxial 119. A bracket fixed to the lower surface of the support plate 162 provides an intermediate connection point for the first coaxial 119, ensuring the coaxiality of the first coaxial 119.

[0053] These are all standard installation methods, and will not be described in detail in this article.

[0054] In some embodiments, see Figures 1 to 4 The paper receiving mechanism 100 also includes a front guide plate 140 installed at the front end of the machine frame 200, which stops the front side of the paper. The front guide plate 140 stops the front end of the paper to ensure that the front face of the paper stack is neat.

[0055] The front baffle 140 is also equipped with an inclined guide spring 141, which can restrict the paper being conveyed from above, organize the paper, prevent the paper from arching upwards in the middle or on both sides, and improve the paper organizing effect.

[0056] Optionally, see Figures 3 to 6 A horizontal slide 150 extending forward and backward is provided on the frame 200 or support plate 162. The upper end of the front baffle 140 is mounted on the slider of the horizontal slide 150. Driven by the horizontal slide 150, it can move forward and backward according to different paper sizes to meet the neatness requirements of different paper sizes.

[0057] A rear baffle 201 is also installed on the machine frame 200 to prevent paper from falling from the rear.

[0058] In some embodiments, see Figures 14 to 18 The paper receiving mechanism also includes a rear paper pushing structure 500 mounted on the machine frame 200 and symmetrically arranged on both sides. The rear paper pushing structure 500 is located behind the paper alignment drive assembly 120. The rear paper pushing structure 500 includes a rear paper pushing plate 501 and a paper pushing slide 502 mounted on the machine frame 200. The rear paper pushing plate 501 is mounted on the paper pushing slider of the paper pushing slide 502. When the front end of the paper being conveyed passes the rear paper pushing plate 501, the paper pushing slide 502 pushes the rear paper pushing plate 501 to contact the rear end of the paper 600, thus helping to convey the paper 600 forward.

[0059] In the above embodiments, the descriptions of each embodiment have different focuses. For parts that are not described in detail or recorded in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0060] Based on the same inventive concept, see [link to inventive concept] Figure 1 and Figure 2 This application also provides a printing press, including the aforementioned paper receiving mechanism 100.

[0061] The installation of this paper receiving mechanism 100 makes it particularly convenient to sort and retrieve documents, especially when printing large batches of documents. This facilitates subsequent binding, storage, and other operations, further enhancing the convenience and efficiency of the entire printing process, reducing the time users spend sorting and stacking documents, and greatly improving user convenience.

[0062] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
