Description

Technical Field

[0001] The present invention relates to the technical field of paper conveying, and particularly to a stacking and forming assembly mechanism for paper preparation and conveying. Background Art

[0002] In the process of paper preparation and processing, the paper stacking mechanism plays a crucial role. Among them, the roller, as a key component in the paper conveying and stacking links, its performance directly affects the stability of the entire production process and the product quality.

[0003] Currently, at the paper output end of the paper stacking mechanism, the commonly used rollers are extremely prone to aging problems after long-term use. On the one hand, the common rubber rollers will gradually wear and age on the surface after long-term friction with the paper and being affected by environmental factors, resulting in a decrease in the surface friction force. This makes it easy to slip when conveying the paper, and it is impossible to accurately convey the paper to the designated position for stacking, seriously affecting the stacking accuracy and efficiency. On the other hand, although the grooved metal rollers are relatively durable, under the long-term mechanical stress and the repeated friction of the paper, the surface grooves will gradually become smooth, which will also weaken the driving ability for the paper, resulting in unstable paper conveying and thus affecting the stacking neatness.

[0004] In addition, since the pressure on different parts of the paper is not uniform during the conveying process, the wear degrees of the respective roller shafts will be different, exacerbating the aging problem of the rollers. And the aged rollers will not only affect the paper conveying and stacking effects, but may also cause damage to the paper itself, such as scratching and wrinkling, reducing the quality of the paper. Once the rollers have aging problems, the traditional solution is often to replace the entire roller shaft, which is not only costly but also requires shutdown operation, greatly reducing the production efficiency. Summary of the Invention

The bottom of the first clamping plate extends into the first sliding groove and is slidably connected. A first spring connected to the first clamping plate at one end is arranged inside the first sliding groove.

[0009] The present invention is further arranged such that second telescopic rods are provided at a position above the winding shaft inside the machine body. There are two groups of the second telescopic rods. The output ends of the two groups of second telescopic rods are respectively fixedly connected with a cutting knife and a first push plate.

[0010] The present invention is further configured such that a docking mechanism is provided at a position on one side of the machine body close to the conveying roller. The docking mechanism includes a fixed frame fixedly connected to the machine body. Second chutes are symmetrically formed at the top and bottom positions inside the fixed frame.

[0013] Advantages of a stacking and forming assembly mechanism for paper preparation and conveying of the present invention: 1. Through a unique structural design, the present invention realizes the convenient replacement of the rubber layer. A winding shaft is provided inside the roller body of the conveying roller, and the rubber layer is wound on its surface. The bottom opening cooperates with structures such as a flap and a first spring buffer, making the fixing and replacement operations of the rubber layer convenient. Components such as the first telescopic rod, winding shaft, clamping opening, electromagnet, and first clamping plate of the winding mechanism work together to quickly wind and recycle the waste rubber layer and pull out the new rubber layer. Compared with the traditional method of replacing the entire roller shaft, the downtime is greatly reduced, the production efficiency is improved, and the maintenance cost is reduced.

[0014] 2. During normal operation, the way the flap holds the extension block at the end of the rubber layer and other parts of the rubber layer effectively reduces the protrusions generated after the rubber layer is squeezed, avoids affecting the paper during the paper conveying process, ensures the flatness and stability of the paper conveying, and improves the paper quality. The auxiliary roller located above the output roller inside the machine body plays a role in pressing the paper, further ensuring the smoothness of the paper during conveying, preventing the paper from warping or shifting, and cooperating with the conveying roller to improve the accuracy of paper conveying and stacking.

[0015] 3. In the winding mechanism, the second telescopic rod pushes the first push plate and the cutting knife to cut off the rubber layer, which can accurately control the length of the rubber layer, ensure that the length of the newly replaced rubber layer is appropriate, and meet the conveying requirements. The mutual cooperation of the components such as the third telescopic rod, the second push plate, the pressing plate, the second spring buffer, the movable block, the connecting rod, the movable plate, and the extrusion head of the docking mechanism realizes that the extension block after the rubber layer is cut off is accurately pushed into the opening of the roller body for fixation, ensuring the firmness and stability of the rubber layer installation, and avoiding problems such as loosening and falling off during the conveying process.

[0022] Please refer to Figures 1-7 , a stacking, forming and assembling mechanism for paper preparation and transportation, including a machine body 1. Inside the machine body 1, a conveying roller 12 is rotatably connected. The conveying roller 12 includes end plates 126 rotatably connected to the inner wall of the machine body 1. Between the end plates 126, a roller body 121 is fixedly connected. Inside the roller body 121, a winding shaft 124 rotatably connected to the end plates 126 at both ends is provided. A rubber layer 125 is wound on the surface of the winding shaft 124. An opening is provided at the bottom of the roller body 121. On one side inside the opening, an auxiliary shaft 122 is rotatably connected. On the other side inside the opening, a flap 123 is hinged. A fixing seat one 1211 is fixedly connected at a position inside the roller body 121 close to the flap 123. Inside the fixing seat one 1211, a spring buffer one 1212 is hinged. One end of the spring buffer one 1212 is hinged to the flap 123. A docking port 1261 is penetrated and opened at a position on the outer wall of the end plate 126 corresponding to the opening. Docking rods 1231 are provided at both ends of the flap 123. One end of the docking rod 1231 extends into the docking port 1261. One end of the rubber layer 125 extends to the outside of the roller body 121 through the opening, winds around the roller body 121 for one circle and then inserts into the opening. An extension block 1251 is provided at a position of the end of the rubber layer 125 close to the end plate 126.

[0023] By adopting the above technical solution, the opening at the bottom of the roller body 121 is the passage for the rubber layer 125 to enter and exit. The auxiliary shaft 122 on one side of the opening provides certain support and guidance for the movement of the rubber layer 125. Under the action of the first spring buffer 1212, the flap 123 is pushed and stuck at the opening in the normal state, tightly clamping the rubber layer 125 and the extension block 1251 at its end. The docking port 1261 on the outer wall of the end plate 126 cooperates with the docking rods 1231 at both ends of the flap 123. When replacing the rubber layer 125, the external mechanism pushes the docking rods 1231 to make the flap 123 flip and open towards the inside of the roller body 121 around the hinge point, facilitating the replacement operation of the rubber layer 125. The extension block 1251 at the end of the rubber layer 125 is ingeniously designed. When the rubber layer 125 is replaced, it can smoothly enter the clamping opening 1331 of the winding mechanism 13 for winding and fixing. At the same time, when the paper is being normally conveyed, the extension block 1251 is located at the end of the roller body 121 and does not participate in the conveyance, avoiding affecting the paper conveyance quality.

[0024] A winding mechanism 13 is arranged at the position below the conveying roller 12 inside the machine body 1. The winding mechanism 13 includes a mounting frame 131 slidably connected to the inner wall of the machine body 1. A first telescopic rod 132 fixedly connected to the machine body 1 is arranged at the bottom of the mounting frame 131. A winding shaft 133 is rotatably connected inside the mounting frame 131. A second fixed seat 137 is fixedly connected to the position near the winding shaft 133 at the top of the mounting frame 131. A first push rod 1371 is hinged inside the second fixed seat 137. A second spring 1372 with one end fixedly connected to the mounting frame 131 is arranged on one side of the first push rod 1371. Clamping openings 1331 are formed at both ends of the winding shaft 133 corresponding to the extension blocks 1251. A first chute 1332 is formed at the inner bottom of the clamping opening 1331. An electromagnet 1333 is fixedly connected to one side inside the clamping opening 1331. A first clamping plate 1334 is slidably connected to the other side inside the clamping opening 1331. The bottom of the first clamping plate 1334 extends into the first chute 1332 and is slidably connected. A first spring 1335 with one end connected to the first clamping plate 1334 is arranged inside the first chute 1332. Two groups of second telescopic rods 136 are arranged at the position above the winding shaft 133 inside the machine body 1. The output ends of the two groups of second telescopic rods 136 are respectively fixedly connected with a cutting knife 134 and a first push plate 135.

[0025] By adopting the above technical solution, the electromagnet 1333 is fixed on one side of the clamping mouth 1331. When powered on, it attracts and closes the clamping plate one 1334, and the spring one 1335 assists its reset when powered off. The push rod one 1371 in the fixed seat two 137 at the top of the mounting frame 131 has an outward thrust under the action of the spring two 1372. When the mounting frame 131 rises close to the conveying roller 12, the push rod one 1371 first inserts into the docking port 1261 to dock with the docking rod 1231, pushing the flap 123 to open, creating conditions for winding up the waste rubber layer 125 or introducing a new rubber layer 125. The two groups of telescopic rods two 136 above the winding shaft 133 in the machine body 1 have clear division of labor. After the rubber layer 125 is wound to an appropriate length, the cutting knife 134 is pushed to cut off, forming a new extension block 1251. The other group is connected to the push plate one 135 to assist in the cutting operation, ensuring the efficient progress of the rubber layer 125 replacement process.

[0026] A docking mechanism 14 is provided at a position on one side of the machine body 1 close to the conveying roller 12. The docking mechanism 14 includes a fixed frame 141 fixedly connected to the machine body 1. Symmetrically arranged sliding grooves two 1411 are opened at the top and bottom inside the fixed frame 141. A push plate two 142 is slidably connected inside the fixed frame 141. A connecting shell 1443 is slidably connected inside the sliding groove two 1411. Push rods three 1421 that are slidably connected to the inner wall of the connecting shell 1443 are fixedly connected to the top and bottom of the push plate two 142. Springs three 1422 connected to the inner wall of the connecting shell 1443 are arranged at the ends of the push rods three 1421 located inside the connecting shell 1443. One end of the connecting shell 1443 away from the fixed frame 141 is fixedly connected to a pressing plate 144, and through holes 1442 are symmetrically opened at both ends of the pressing plate 144.

[0027] By adopting the above technical solution, when the telescopic rod three 1423 pushes the push plate two 142, the push plate two 142 drives the connecting shell 1443 and the pressing plate 144 to move through the push rod three 1421. The pressing plate 144 presses on the surface of the conveying roller 12 to press and fix the rubber layer 125. The through holes 1442 symmetrically arranged at both ends of the pressing plate 144 cooperate with the pressing plates 1452 on the subsequent movable plate 145 to achieve precise pushing and fixing of the extension block 1251, ensuring the stability of the rubber layer 125 after replacement and guaranteeing the smooth completion of the entire rubber layer 125 replacement process.

[0028] On one side of the pressing plate 144 close to the fixed frame 141, a limiting frame 1441 is provided. Inside the limiting frame 1441, a movable plate 145 is slidably connected. There are two movable plates 145 in total. At the position of the outer wall of the movable plate 145 corresponding to the through hole 1442, a pressing plate 1452 is provided. The pressing plate 1452 extends into the through hole 1442 and is slidably connected. At one end of the two movable plates 145 close to each other, a pressing block 1453 is provided. Between the pressing blocks 1453, a pressing head 146 is slidably connected. On the side of the pressing head 146 close to the second push plate 142, a fixing rod 1461 is fixedly connected. One end of the fixing rod 1461 is fixedly connected to the second push plate 142. At the position of the fixed frame 141 outside close to the second push plate 142, a mounting plate 1412 is provided. On the top of the mounting plate 1412, a telescopic rod three 1423 with an output end fixedly connected to the second push plate 142 is fixedly connected.

[0029] By adopting the above technical solution, the limiting frame 1441 plays a role in limiting and guiding the movable plate 145 to ensure that it slides along the specified path. For the two symmetrical movable plates 145, the pressing plates 1452 on their outer walls are precisely matched with the through holes 1442 of the pressing plate 144. When moving, the extension block 1251 is pushed to the predetermined bayonet. The pressing blocks 1453 at one end of the movable plate 145 are slidably connected to the pressing head 146. The second push plate 142 pushes the pressing head 146 through the fixing rod 1461 to press the pressing blocks 1453, so that the movable plate 145 moves towards the end of the fixed frame 141, driving the pressing plate 1452 to withdraw, and completing the fixing of the extension block 1251. The mounting plate 1412 outside the fixed frame 141 provides an installation basis for the telescopic rod three 1423. The telescopic rod three 1423 pushes the second push plate 142 to slide inside the fixed frame 141, realizing the pressing and fixing of the pressing plate 144 on the conveying roller 12 and the rubber layer 125 and subsequent operations, ensuring the smooth progress of the rubber layer 125 replacement process.

[0030] On the side of the movable plate 145 close to the second push plate 142, a movable opening 1451 is provided. At the position of the outer wall of the second push plate 142 corresponding to the movable opening 1451, a spring buffer two 1424 is fixedly connected. At the end of the spring buffer two 1424 close to the movable opening 1451, a movable block 1425 is fixedly connected. The movable block 1425 is slidably connected to the inner wall of the movable opening 1451. Inside the movable opening 1451, a spring four 1426 with one end connected to the movable block 1425 is provided. The top end of the movable block 1425 penetrates through the movable opening 1451 and extends to its outside. At the end of the movable block 1425 located outside the movable opening 1451, a connecting rod 143 is fixedly connected. Both ends of the connecting rod 143 are hinged with a push rod two 1431.

[0031] By adopting the above technical solution, the movable opening 1451 of the movable plate 145 is the key to connecting the second push plate 142 and its own movement. The second spring buffer 1424 on the outer wall of the second push plate 142 is connected to the movable block 1425. When the second push plate 142 moves, the second spring buffer 1424 drives the movable block 1425 to slide in the movable opening 1451. The fourth spring 1426 in the movable opening 1451 provides buffering and reset force for the movable block 1425, which can be compressed when encountering resistance to prevent component collision and damage. The movable block 1425 passes through the movable opening 1451 and is connected to the connecting rod 143, converting the linear motion of the second push plate 142 into the swinging motion of the connecting rod 143. The push rod 1431 hinged at both ends of the connecting rod 143 plays a crucial role. When the second push plate 142 pushes the movable plate 145, the connecting rod 143 drives the push rod 1431 to dock with the docking rod 1231 in the docking port 1261. Subsequently, the push rod 1431 pushes the docking rod 1231 to open the flap 123, creating conditions for fixing the extension block 1251 and ensuring the smooth replacement process of the rubber layer 125.

[0032] The working principle and usage process of the embodiment of the present invention: The winding shaft 124 is rotationally connected to the end plate 126 with damping. When the flap 123 is in the normal state, it will be pushed and stuck at the opening, and at the same time, the rubber layer 125 will be clamped. The extension block 1251 at the end of the rubber layer 125 will be clamped by the flap 123, and the remaining part of the end will be stuck at the position below the flap 123. Such clamping can reduce the protrusion generated after the rubber layer 125 is extruded, preventing interference during paper feeding. And the position of the extension block 1251 is at the end of the roller 121 and does not participate in paper feeding. An auxiliary roller 11 is rotationally connected above the conveying roller 12 inside the machine body 1, and the auxiliary roller 11 plays a role in pressing the paper.

[0033] With Figure 6 、 Figure 7For example, after the conveying roller 12 has been used for a certain period of time, the rubber layer 125 surrounding its surface needs to be replaced. The conveying roller 12 rotates to rotate the opening to the bottom position, and then the telescopic rod 132 in the winding mechanism 13 pushes the mounting bracket 131 to rise. The rising of the mounting bracket 131 drives the winding shaft 133 and the first push rod 1371 closer to the conveying roller 12. The first push rod 1371 first inserts into the inside of the docking port 1261 to dock with the docking rod 1231, and then continues to push the rising docking rod 1231. By pushing the docking rod 1231, the flap 123 is flipped open towards the inside of the roller body 121. While the flap 123 is open and loses the clamping of the rubber layer 125, the winding shaft 133 will be close to the roller body 121. When the flap 123 is open, the extension block 1251 will fall into the clamping port 1331 due to gravity. Then, the electromagnet 1333 is energized to pull the first clamping plate 1334 to clamp the extension block 1251. Then, the winding mechanism 13 descends, and while the first push rod 1371 disengages from the docking rod 1231, the winding shaft 133 is rotated by the driving motor. The rotation of the winding shaft 133 winds the waste rubber layer 125 around itself. When winding, the conveying roller 12 will rotate clockwise by pulling the rubber layer 125.

[0034] When the waste rubber layer 125 is completely separated from the roller body 121, the winding mechanism 13 rises to push open the flap 123 again, and then the winding shaft 133 continues to rotate to wind the new rubber layer 125 inside the roller body 121 around its outside. When the winding shaft 133 winds the rubber layer 125 to be able to surround the roller body 121 for one week, it stops rotating. Then, the winding mechanism 13 descends, and the first push rod 1371 disengages from the docking rod 1231. Then, the conveying roller 12 rotates counterclockwise to wind the pulled-out rubber layer 125 around itself for one circle. The telescopic rod 136 will push the first push plate 135 and the cutting knife 134 to cut off the rubber layer 125. After the cutting edge of the cutting knife 134 cuts off the rubber layer 125, the extension block 1251 will be formed. Since the extension block 1251 is the extra part, after the rubber layer 125 surrounds one circle, the extension block 1251 will fall on the surface of the rubber layer 125.

[0035] When the rubber layer 125 is cut off, the opening of the conveying roller 12 faces downward. Then, the conveying roller 12 rotates counterclockwise by seventy degrees to align with the docking mechanism 14. Then, the third telescopic rod 1423 drives the second push plate 142, which in turn drives the pressing plate 144 to press on the surface of the conveying roller 12, and at the same time presses and fixes the rubber layer 125. Since the pressing plate 144 cannot move after docking with the conveying roller 12, when the third telescopic rod 1423 continues to push the second push plate 142, the third spring 1422 will be compressed. Therefore, when the second push plate 142 moves, it will drive the connecting rod 143 and the movable plate 145 through the second spring buffer 1424 and the movable block 1425. At the same time, the second push plate 142 will also push the extrusion head 146 through the fixed rod 1461. During the movement, the second push rod 1431 hinged at both ends of the connecting rod 143 will first dock with the docking rod 1231 through the docking port 1261. Then, as the second push plate 142 continues to push, the second push rod 1431 will push the docking rod 1231 to open the flap 123. At the same time, the extrusion plate 1452 of the movable plate 145 will push the extension block 1251 into the bayonet through the through hole 1442. After the extension block 1251 enters the bayonet, the movable plate 145 fits with the pressing plate 144. After the fit, the movable plate 145, the movable block 1425, and the connecting rod 143 cannot move closer to the conveying roller 12. When the second push plate 142 continues to push, it will compress the second spring buffer 1424. However, the second push plate 142 will continue to push the extrusion head 146 through the fixed rod 1461. When the extrusion head 146 moves, it will move the movable plate 145 towards the end of the fixed frame 141 by extruding the extrusion block 1453. When the movable plate 145 moves, it will drive the extrusion plate 1452 out of the through hole 1442 and the docking port 1261, leaving the extension block 1251 inside the opening. Then, the third telescopic rod 1423 pulls the second push plate 142 to quickly retract, so that the second push rod 1431 quickly disengages from the docking rod 1231, and the flap 123 quickly clamps and fixes the extension block 1251 and the rubber layer 125.

[0036] In summary, compared with the prior art, the embodiments of the present invention have the following advantages: Advantage 1: Through the coordinated action of the winding shaft 124, the flap 123 inside the conveying roller 12 and the winding mechanism 13, the present invention realizes the rapid replacement of the rubber layer 125. When the rubber layer 125 is worn, there is no need to stop the machine to replace the entire roller shaft. Only need to roll up the old rubber layer 125 through the winding mechanism 13 and replace it with a new rubber layer 125, which greatly saves time and cost and improves production efficiency. This advantage benefits from the ingenious design of the winding shaft 124 and the flap 123, as well as the precise control of components such as the electromagnet 1333 and the first clamping plate 1334 in the winding mechanism 13.

[0037] Advantage 2: The design of the conveying roller 12 effectively prevents the paper from slipping during the conveying process. The rubber layer 125 is tightly clamped by the flap 123 and the winding shaft 124, ensuring its stability and uniformity on the roller body 121, thereby improving the accuracy and efficiency of paper conveying. In addition, the setting of the auxiliary roller 11 further enhances the conveying stability of the paper, preventing the paper from shifting and wrinkling during the conveying process.

[0038] Advantage 3: The structure of the conveying roller 12 of the present invention reduces the wear of the roller shaft during long-term use by optimizing the fixing method of the rubber layer 125. The design of the extension block 1251 at the end of the rubber layer 125 enables the rubber layer 125 to enter and leave the roller body 121 more smoothly during replacement, avoiding local excessive wear of the roller shaft caused by uneven friction. At the same time, the setting of the flap 123 and the spring buffer 1212 also effectively buffers the impact of the paper on the roller shaft, further extending the service life of the roller shaft.

[0039] Advantage 4: The intelligent design of the winding mechanism 13 and the docking mechanism 14 makes the replacement process of the rubber layer 125 more automated and convenient. The coordinated action of components such as the electromagnet 1333, the clamping plate 1334, and the push rod 1371 realizes the automatic winding and fixing of the rubber layer 125; while the components such as the push plate 142, the movable plate 145, and the extrusion head 146 in the docking mechanism 14 ensure the stability and accuracy of the rubber layer 125 after replacement through precise docking and clamping operations. These intelligent and automated designs reduce manual intervention and improve the safety and reliability of the operation.

[0040] Advantage 5: The stacking and forming assembly mechanism of the present invention effectively prevents damage to the paper during the conveying and stacking processes, such as scratching and wrinkling, by optimizing the stability and accuracy of the paper conveying process, thereby improving the quality of the paper. In addition, the rapid replacement and maintenance of the rubber layer 125 also reduce the impact of roller shaft aging on the paper quality, ensuring the stability and consistency of the production process.
