Abstract
Description
Technical Field
[0001] The present application relates to the technical field of printing equipment, and in particular to an anti-wrinkle device for paper printing. Background Art
[0002] In the paper printing process, ensuring that the paper remains flat and wrinkle-free is one of the key factors in ensuring printing quality.
[0003] In the related art, an anti-wrinkle device for a printing press is designed, which includes a material storage box and a base plate. The base plate is slidably connected to the material storage box. A spring is provided between one side of the base plate and the material storage box. A limit baffle is fixedly provided on the side of the material storage box away from the spring. The spring pushes the base plate toward the limit baffle. An opening is provided on one side of the material storage box. A loading assembly is provided near the opening of the material storage box. The loading assembly is used to transport the paper in the material storage box to the printing position. When in use, the paper is stacked between the base plate and the limit baffle. The spring presses and fixes the paper between the base plate and the limit baffle. The edge of the paper is abutted by the base plate and the limit baffle, preventing it from bending at will, thereby reducing the phenomenon of the paper being bent and wrinkled due to external forces. The loading assembly transports the top layer of paper from the outlet of the material storage box to the printing position to complete the printing step.
[0004] During the implementation of this application, it was discovered that this technology has at least the following problems: In this technology, when inserting paper, it is necessary to first press down the bottom plate, then place the paper on the bottom plate, and then release the bottom plate. Under the action of the spring, the bottom plate pushes the paper until it abuts against the limit stop. However, in actual operation, when inserting paper, the bottom plate needs to be kept pressed down. The depressed part of the bottom plate will interfere with the insertion of the paper, making it difficult to load the paper. Utility Model Content
[0005] In order to facilitate the insertion of paper and improve the convenience of loading paper into the device, the present application provides a paper printing anti-wrinkle device.
[0006] The paper printing anti-wrinkle device provided in this application adopts the following technical solution:
[0007] A paper printing anti-wrinkle device includes a material storage box, a base plate, and a feeding assembly. The base plate is slidably connected to the material storage box, a tensioning spring is provided between one side of the base plate and the material storage box, and an opening is provided on one side of the material storage box. The feeding assembly is used to transport the paper in the material storage box to a printing position. A paper pressing board is provided on the side of the material storage box away from the tensioning spring, and the end of the paper pressing board away from the opening is rotatably connected to the material storage box. A connecting piece is provided between the end of the paper pressing board close to the opening and the material storage box. The end of the paper pressing board close to the opening is connected to or separated from the material storage box through the connecting piece, and the tensioning spring drives the base plate close to the paper pressing board.
[0008] By adopting the above technical solution, when it is necessary to put in paper, the paper pressing plate can be separated from the storage box through the connecting piece, and the paper pressing plate can be turned over. At this time, there is no need to keep pressing the bottom plate, and the paper can be directly stacked on the bottom plate. Then, the bottom plate is pressed down by pressing the paper, and the paper pressing plate is closed. Finally, the paper pressing plate and the storage box are connected by the connecting piece so that the paper is fixed between the bottom plate and the paper pressing plate, thereby avoiding as much as possible the problem in the existing technology that it is difficult to load paper due to the need to keep pressing the bottom plate, facilitating the insertion of paper and improving the convenience of loading paper into the device.
[0009] Preferably, the storage box is provided with a slot on the side away from the opening, movable slots are provided on both sides of the slot, and a movable shaft is fixedly provided on the end of the pressing paper away from the opening. The movable shaft rotates and slides in the movable slot, and the pressing paper can be inserted into the slot.
[0010] By adopting the above technical solution, the rotation and sliding of the movable shaft in the movable groove enables the paper press to be flexibly opened and closed. After the paper press is opened, the paper press is inserted into the slot, which improves the stability of the paper press in the opened state.
[0011] Preferably, the connecting part includes a lock buckle, a rotating shaft, and a locking pin. The lock pin is fixed on the outer wall of the storage box, the rotating shaft is fixed on the side wall of the pressure paper board, the lock buckle rotates with the rotating shaft, and a locking hole is provided on the lock buckle, and the locking pin can be inserted into the locking hole.
[0012] By adopting the above technical solution, when it is necessary to open or close the paper pressing plate, the personnel only need to turn the lock buckle to rotate the lock buckle around the rotating shaft to achieve quick connection or separation between the lock mouth and the lock pin. When the lock pin is inserted into the lock mouth, the paper pressing plate is locked on the storage box; when the lock pin is disengaged from the lock mouth, the paper pressing plate can be flipped open, thereby quickly completing the fixation or unlocking between the paper pressing plate and the storage box, thereby improving the efficiency of paper insertion.
[0013] Preferably, the connecting member further comprises a torsion spring, one end of the torsion spring is fixedly connected to the lock catch, and the other end of the torsion spring is fixedly connected to the rotating shaft, and the torsion spring drives the lock opening close to the lock pin.
[0014] By adopting the above technical solution, when the operator pushes the lever to unlock, the torsion spring will be compressed to store energy; and when the lever is released, the torsion spring releases energy, prompting the lock to quickly reset and re-engage tightly with the lock pin, thereby ensuring that the connection between the paper pressing plate and the storage box is firm and reliable.
[0015] Preferably, the loading assembly includes a movable frame, a sliding block, a conveying roller, and a compression spring. The movable frame is fixedly arranged on the side of the pressure paper board away from the bottom plate. The sliding block is slidably arranged on the movable frame in the direction close to or away from the bottom plate. The conveying roller rotates in coordination with the sliding block. A through opening is opened on the pressure paper board, and the conveying roller can pass through the through opening and extend into the storage box. The compression spring drives the sliding block close to the pressure paper board.
[0016] By adopting the above technical solution, the elastic force of the compression spring makes the sliding block always tend to approach the paper pressing board, thereby driving the conveying roller to fit closely to the surface of the paper, and providing sufficient friction when conveying the paper to avoid slipping or poor conveying as much as possible. When loading the material, the conveying roller is driven to rotate, and the conveying roller rubs against the surface of the paper to convey the paper to the printing position.
[0017] Preferably, a handle is fixedly provided at one end of the paper pressing board close to the opening.
[0018] By adopting the above technical solution, the setting of the handle provides a convenient fulcrum for the operator to operate the paper press. When the paper press needs to be opened or closed, the operator can directly hold the handle to operate, which is easier and more labor-saving, thereby improving work efficiency.
[0019] Preferably, a guide rod is fixedly provided on the side of the bottom plate away from the paper pressing plate, the guide rod passes through the storage box and slides with the storage box, and the tightening spring is sleeved on the guide rod.
[0020] By adopting the above technical solution, the guide rod can provide stable guidance for the movement of the bottom plate, ensuring that the bottom plate moves smoothly in a straight line under the action of the tensioning spring. At the same time, the tensioning spring is sleeved on the guide rod, which can effectively prevent the spring from bending during the extension and contraction process, ensuring that the force of the spring is evenly transmitted to the bottom plate, so that the bottom plate exerts stable pressure on the paper, further improving the reliability and stability of the equipment and ensuring the anti-wrinkle effect of the paper.
[0021] Preferably, a limiting block is fixedly provided at one end of the guide rod away from the bottom plate, and the limiting block can be abutted against the side of the storage box away from the paper pressing board.
[0022] By adopting the above technical solution, the limit block can limit the maximum extension length of the guide rod, thereby preventing the bottom plate from sliding excessively out of the storage box under the action of the tensioning spring, and minimizing the occurrence of equipment failure or damage caused by the bottom plate falling out.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. By setting up a rotatable paper pressing plate and connecting parts, the problem of difficulty in loading paper due to the need to continuously press the bottom plate is avoided as much as possible, which facilitates the insertion of paper and improves the convenience of paper loading in the equipment, solves the difficulty of paper loading, improves paper loading efficiency, and reduces the complexity of operation;
[0025] 2. By setting up a lock buckle, lock mouth, lock pin, rotating shaft, and torsion spring, when the cardboard needs to be opened or closed, the operator only needs to turn the lever to drive the rotating shaft to rotate, so that the lock buckle rotates around the rotating shaft to achieve quick connection or separation between the lock mouth and the lock pin;
[0026] 3. By setting up a movable frame, sliding block, conveyor roller, and compression spring, under the action of the compression spring, the conveyor roller fits tightly to the surface of the paper, providing sufficient friction when conveying the paper, driving the conveyor roller to rotate when loading, and the conveyor roller conveys the paper to the printing position.

[0033] The following is combined with Figure 1-5 This application is described in further detail.
[0034] The present application embodiment discloses a paper printing anti-wrinkle device. Figure 1 , which includes a storage box 1, a base plate 2, and a loading assembly 31. The base plate 2 is slidably connected to the storage box 1, and a tensioning spring 21 is provided between one side of the base plate 2 and the storage box 1. An opening 11 is provided on one side of the storage box 1. The loading assembly 31 is used to transport the paper in the storage box 1 to the printing position. A pressing paper 3 is provided on the side of the storage box 1 away from the tensioning spring 21, and the pressing paper 3 is wider than the base plate 2. The pressing paper 3 is rotatably connected to the storage box 1 at one end away from the opening 11, and a connecting member 4 is provided between the end of the pressing paper 3 close to the opening 11 and the storage box 1. The end of the pressing paper 3 close to the opening 11 is connected to or separated from the storage box 1 through the connecting member 4. A handle 34 is also fixedly provided on the end of the pressing paper 3 close to the opening 11. The tensioning spring 21 drives the base plate 2 close to the pressing paper 3.
[0035] Reference Figure 5 The paper pressing plate 3 is provided with a rotating roller 35 on one side thereof which rotates toward the bottom plate 2 , and the rotating roller 35 is used for contacting the surface of the paper.
[0036] Reference Figures 1 to 5 To load paper, the end of the paper pressing plate 3 near the opening 11 is separated from the magazine 1 using the connector 4. The grip 34 is then grasped to unfold the paper pressing plate 3. The paper is then stacked on the bottom plate 2. The bottom plate 2 is then lowered by pressing down on the paper, and the paper pressing plate 3 is closed. Finally, the paper pressing plate 3 is connected to the magazine 1 using the connector 4, securing the paper between the bottom plate 2 and the paper pressing plate 3. During use, the loading assembly 31 is used to transport the paper in the magazine 1 to the printing position, and the rotating roller 35 reduces the friction between the paper pressing plate 3 and the paper.
[0037] In order to improve the stability of the paperboard 3 in the open state, refer to Figure 3 and Figure 4 The storage box 1 has a slot 12 on the side away from the opening 11, and movable slots 13 on both sides of the slot 12. A movable shaft 32 is fixedly provided on the end of the paperboard pressing plate 3 away from the opening 11. The diameter of the movable shaft 32 is consistent with the thickness of the paperboard pressing plate 3, and the length of the movable shaft 32 is greater than the width of the paperboard pressing plate 3. One end of the movable shaft 32 rotates and slides in one of the movable slots 13, and the other end rotates and slides in the other movable slot 13, so that the paperboard pressing plate 3 can be inserted into the slot 12. After the paperboard pressing plate 3 is opened, the paperboard pressing plate 3 is rotated to face the opening direction of the slot 12 and inserted into the slot 12. When the paperboard pressing plate 3 is located in the slot 12, the paperboard pressing plate 3 cannot move freely, thereby improving the stability of the paperboard pressing plate 3 in the opened state.
[0038] In order to facilitate the connection or separation of the end of the pressing paper 3 close to the opening 11 with the storage box 1, refer to Figure 2The connecting member 4 includes a lock catch 41, a rotating shaft 42, a lock pin 43, a driving rod 44, and a torsion spring 45. The lock pin 43 is fixed to the outer wall of the storage box 1, and the rotating shaft 42 is fixed to the side wall of the cardboard pressing board 3. The lock catch 41 is rotatably matched with the rotating shaft 42. A lock hole 411 is provided on the lock catch 41, and the lock pin 43 can be inserted into the lock hole 411. A driving rod 44 is fixedly provided on the lock catch 41, and the driving rod 44 is located on the side of the rotating shaft 42 away from the lock hole 411. A guide slope 412 is provided on the side of the lock catch 41 away from the driving rod 44. The guide slope 412 can abut and slide against the circumference of the lock pin 43. One end of the torsion spring 45 is fixedly connected to the lock catch 41, and the other end of the torsion spring 45 is fixedly connected to the rotating shaft 42. The torsion spring 45 drives the lock hole 411 close to the lock pin 43.
[0039] In order to facilitate the transportation of the paper in the storage box 1 to the printing position, refer to Figure 1 The loading assembly 31 includes a movable frame 311, a sliding block 312, a conveying roller 313, and a compression spring 314. The movable frame 311 is fixedly arranged on the side of the paperboard 3 away from the base plate 2. The sliding block 312 is slidably arranged on the movable frame 311 in a direction close to or away from the base plate 2. The conveying roller 313 rotates in coordination with the sliding block 312. A motor 315 is also fixedly arranged on the sliding block 312, and the drive shaft of the motor 315 is coaxially fixed with the conveying roller 313. A through opening 33 is formed on the paperboard 3, and the conveying roller 313 can pass through the through opening 33 and extend into the storage box 1. The compression spring 314 drives the sliding block 312 close to the paperboard 3. The peripheral wall of the conveying roller 313 abuts against the paper in the storage box 1. The elastic force of the compression spring 314 is less than the elastic force of the tension spring 21.
[0040] In order to optimize the stability and trajectory of the bottom plate 2, refer to Figure 1 A guide rod 22 is fixedly mounted on the side of the bottom plate 2 away from the paperboard pressing plate 3. The guide rod 22 extends through the material storage box 1 and slidably engages with the material storage box 1. The tensioning spring 21 is mounted on the guide rod 22. A limit block 221 is fixedly mounted on the end of the guide rod 22 away from the bottom plate 2. The limit block 221 can abut against the side of the material storage box 1 away from the paperboard pressing plate 3. The guide rod 22 provides guidance for the sliding of the bottom plate 2, minimizing its displacement during movement. The limit block 221 prevents the tensioning spring 21 from overextruding the bottom plate 2 when the paperboard pressing plate 3 is opened.
[0041] The implementation principle of a paper printing wrinkle-proof device according to an embodiment of the present application is as follows: when inserting printing paper, first operate the toggle lever 44 to move the lock 41 of the lock 41 away from the lock pin 43. Then flip the paperboard 3 over and insert it into the slot 12. Then stack the paper flat on the bottom plate 2, pull the paperboard 3 out of the slot 12, pass it through the through hole and press the bottom plate 2 by pressing the paper. Then close the paperboard 3, the guide slope 412 of the lock 41 contacts the lock pin 43, and the lock 41 deflects until the lock port 411 of the lock 41 is opposite to the lock pin 43. The lock port 411 is close to the lock pin 43 to connect the end of the paperboard 3 close to the opening 11 with the storage box 1. Finally, release the pressure on the paper, tighten the spring 21 and push the bottom plate 2 so that the paper is close to the paperboard 3. The conveying roller 313 contacts the paper under the action of the compression spring 314 . When in use, the motor 315 drives the conveying roller 313 to rotate. The conveying roller 313 rotates to push the paper out of the opening 11 and smoothly convey it to the printing position.
[0042] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
