Description

Technical Field

[0001] The present invention relates to the technical field of paper conveying, and in particular to a stacking, forming and assembling mechanism for preparing and conveying paper. Background Art

[0002] The paper stacking mechanism plays a vital role in the paper preparation and processing process. Rollers, as key components in the paper conveying and stacking process, have a direct impact on the stability of the entire production process and product quality.

[0003] Currently, the rollers commonly used at the paper output end of paper stacking mechanisms are prone to aging problems after long-term use. On the one hand, the surface of common rubber rollers will gradually wear and age after prolonged friction with paper and the influence of environmental factors, resulting in a decrease in surface friction. This makes it easy for paper to slip when conveying, and it is impossible to accurately convey paper to the designated location for stacking, seriously affecting the accuracy and efficiency of stacking. On the other hand, although textured metal rollers are relatively durable, their surface texture will gradually become smooth under long-term mechanical stress and repeated friction with paper, which will also weaken the ability to drive the paper, resulting in unstable paper conveying and affecting the neatness of stacking.

[0004] Furthermore, because different parts of the paper are subjected to uneven pressure during conveyance, the wear of each roller varies, exacerbating roller aging. Aged rollers not only affect paper conveyance and stacking, but can also damage the paper itself, causing scratches and wrinkles, reducing its quality. Traditionally, the solution to roller aging is to replace the entire roller, which is not only costly but also requires downtime, significantly reducing production efficiency.

[0013] Beneficial effects of the stacking, forming and assembling mechanism for paper preparation and transportation of the present invention:

[0014] 1. The present invention facilitates the replacement of rubber layers through a unique structural design. The conveyor roller is equipped with an unwinding shaft, on which the rubber layer is wound. The bottom opening, combined with flaps and spring buffers, facilitates the fixing and replacement of the rubber layer. The rewinding mechanism's telescopic rod, rewinding shaft, clamping jaws, electromagnet, and clamping plates work together to quickly rewind the discarded rubber layer and pull out a new one. Compared to traditional methods of replacing the entire roller shaft, this significantly reduces downtime, improves production efficiency, and reduces maintenance costs.

[0015] 2. During normal operation, the flaps clamp the extension blocks at the ends of the rubber layer and other parts of the rubber layer, effectively reducing the protrusions caused by the rubber layer being squeezed, preventing any impact on the paper during transportation, ensuring smooth and stable transportation, and improving paper quality. An auxiliary roller located above the output roller inside the machine body acts as a paper pressure, further ensuring smooth paper transportation and preventing paper from warping or shifting. This, in conjunction with the transport roller, improves the accuracy of paper transportation and stacking.

[0016] 3. In the rewinding mechanism, telescopic rod 2 pushes push plate 1 and the cutter to cut the rubber layer, precisely controlling the length of the rubber layer and ensuring the newly replaced rubber layer is the appropriate length to meet conveying requirements. The coordination of the docking mechanism's telescopic rod 3, push plate 2, pressure plate, spring buffer 2, movable block, connecting rod, movable plate, and extrusion head ensures that the extended block, after the rubber layer is cut, is accurately pushed into the roller opening and fixed. This ensures the secure and stable installation of the rubber layer and prevents loosening and falling during conveying. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] See also Figure 1-Figure 7 A stacking and forming assembly mechanism for preparing and conveying paper includes a machine body 1, a conveying roller 12 is rotatably connected inside the machine body 1, the conveying roller 12 includes an end plate 126 rotatably connected to the inner wall of the machine body 1, a roller body 121 is fixedly connected between the end plates 126, an unwinding shaft 124 is provided inside the roller body 121 at both ends of which are rotatably connected to the end plates 126, a rubber layer 125 is wound on the surface of the unwinding shaft 124, an opening is opened at the bottom of the roller body 121, an auxiliary shaft 122 is rotatably connected to one side of the opening, a flap 123 is hinged to the other side of the opening, and the inside of the roller body 121 is close to the flap 123. A fixing seat 1211 is fixedly connected in position, a spring buffer 1212 is hinged inside the fixing seat 1211, one end of the spring buffer 1212 is hinged to the flap 123, a docking port 1261 is penetrated at the position corresponding to the opening on the outer wall of the end plate 126, docking rods 1231 are provided at both ends of the flap 123, one end of the docking rod 1231 extends to the inside of the docking port 1261, one end of the rubber layer 125 extends to the outside of the roller body 121 through the opening, and is inserted into the inside of the opening after being wrapped around the roller body 121, and an extension block 1251 is provided at the end of the rubber layer 125 near the end plate 126.

[0032] By adopting the above-mentioned technical solution, the opening at the bottom of the roller body 121 serves as a passage for the rubber layer 125 to enter and exit. The auxiliary shaft 122 on one side of the opening provides support and guidance for the movement of the rubber layer 125. Under normal conditions, the flap 123 is pushed and clamped in the opening by the action of the spring buffer 1212, tightly clamping the rubber layer 125 and the extension block 1251 at its end. The docking ports 1261 on the outer wall of the end plate 126 mate with the docking rods 1231 at each end of the flap 123. When replacing the rubber layer 125, an external mechanism pushes the docking rods 1231, causing the flap 123 to flip open around the hinge point toward the inside of the roller body 121, facilitating the replacement of the rubber layer 125. The extension block 1251 at the end of the rubber layer 125 is cleverly designed. When the rubber layer 125 is replaced, it can smoothly enter the clamping opening 1331 of the winding mechanism 13 for easy winding and fixing. At the same time, when conveying paper normally, the extension block 1251 is located at the end of the roller body 121 and does not participate in conveying, thereby avoiding affecting the quality of paper conveying.

[0033] A winding mechanism 13 is provided inside the machine body 1 below the conveying roller 12. The winding mechanism 13 includes a mounting frame 131 slidably connected to the inner wall of the machine body 1. A telescopic rod 132 fixedly connected to the machine body 1 is provided at the bottom of the mounting frame 131. A retracting shaft 133 is rotatably connected inside the mounting frame 131. A fixing seat 2 137 is fixedly connected to the top of the mounting frame 131 near the retracting shaft 133. A push rod 1371 is hinged inside the fixing seat 2 137. A spring 2 1372 with one end fixedly connected to the mounting frame 131 is provided on one side of the push rod 1371. Two ends of the retracting shaft 133 are provided at positions corresponding to the extension blocks 1251. The clamping jaws 1331 have a sliding groove 1332 at the bottom inner side of the clamping jaws 1331, an electromagnet 1333 is fixedly connected to one side of the clamping jaws 1331, a clamping plate 1334 is slidably connected to the other side of the clamping jaws 1331, the bottom of the clamping plate 1334 extends to the inside of the sliding groove 1332 and is slidably connected, a spring 1335 is provided inside the sliding groove 1332 with one end connected to the clamping plate 1334, a telescopic rod 136 is provided above the retracting shaft 133 inside the machine body 1, and there are two groups of telescopic rods 136, and the output ends of the two groups of telescopic rods 136 are fixedly connected to the cutter 134 and the push plate 135 respectively.

[0034] By adopting the above technical solution, the electromagnet 1333 is fixed to one side of the clamping opening 1331. When energized, it attracts the clamping plate 1334. The spring 1335 assists in resetting it when the power is off. The push rod 1371 in the fixing seat 2 137 at the top of the mounting frame 131 is pushed outward by the spring 2 1372. When the mounting frame 131 rises and approaches the conveyor roller 12, the push rod 1371 first inserts into the docking port 1261 and docks with the docking rod 1231, pushing the flap 123 open, creating conditions for winding the discarded rubber layer 125 or introducing a new rubber layer 125. The two sets of telescopic rods 2 136 above the retracting shaft 133 in the machine body 1 have clear divisions of labor. After the cutter 134 has wound the rubber layer 125 to the appropriate length, it pushes the cutter 134 to cut it off, forming a new extension block 1251. Another set of push plates 135 assists in the cutting operation, ensuring that the replacement process of the rubber layer 125 is carried out efficiently.

[0035] A docking mechanism 14 is provided at a position near the conveying roller 12 on one side of the machine body 1, and the docking mechanism 14 includes a fixed frame 141 fixedly connected to the machine body 1, and a second slide groove 1411 is symmetrically provided at the top and bottom positions inside the fixed frame 141, a push plate 142 is slidably connected inside the fixed frame 141, and a connecting shell 1443 is slidably connected inside the second slide groove 1411, and the top and bottom of the second push plate 142 are fixedly connected to a push rod 3 1421 which is slidably connected to the inner wall of the connecting shell 1443, and the end of the push rod 3 1421 located inside the connecting shell 1443 is provided with a spring 3 1422 connected to the inner wall of the connecting shell 1443, and a pressure plate 144 is fixedly connected to the end of the connecting shell 1443 away from the fixed frame 141, and through-holes 1442 are symmetrically provided at both ends of the pressure plate 144.

[0036] By adopting the above technical solution, when telescopic rod 3 1423 pushes push plate 2 142, push plate 2 142 drives connecting shell 1443 and pressure plate 144 to move via push rod 3 1421. Pressure plate 144 presses against the surface of conveyor roller 12, pressing and securing rubber layer 125. Symmetrical openings 1442 at both ends of pressure plate 144 cooperate with compression plates 1452 on the subsequent movable plate 145 to precisely push and secure extension block 1251, ensuring the stability of rubber layer 125 after replacement and ensuring the smooth completion of the entire rubber layer 125 replacement process.

[0037] A limit frame 1441 is provided on the side of the pressure plate 144 close to the fixed frame 141, and a movable plate 145 is slidably connected inside the limit frame 1441. There are two movable plates 145 in total, and an extrusion plate 1452 is provided on the outer wall of the movable plate 145 corresponding to the through-hole 1442. The extrusion plate 1452 extends into the through-hole 1442 and is slidably connected. An extrusion block 1453 is provided at the end close to the two movable plates 145, and an extrusion head 146 is slidably connected between the extrusion blocks 1453. A fixing rod 1461 is fixedly connected to the side of the extrusion head 146 close to the push plate 2 142, and one end of the fixing rod 1461 is fixedly connected to the push plate 2 142. A mounting plate 1412 is provided on the outside of the fixed frame 141 near the push plate 2 142, and a telescopic rod 3 1423 whose output end is fixedly connected to the push plate 2 142 is fixedly connected to the top of the mounting plate 1412.

[0038] By adopting the above technical solution, the limit frame 1441 acts as a limit guide for the movable plate 145, ensuring that it slides along the specified path. The two symmetrical movable plates 145, whose outer wall extrusion plates 1452 precisely match the openings 1442 of the pressure plate 144, push the extension block 1251 to the predetermined slot during movement. The extrusion block 1453 at one end of the movable plate 145 is slidably connected to the extrusion head 146. The second push plate 142 pushes the extrusion head 146 via the fixed rod 1461, squeezing the extrusion block 1453, causing the movable plate 145 to move toward the end of the fixed frame 141, driving the extrusion plate 1452 to withdraw, and completing the fixation of the extension block 1251. The mounting plate 1412 outside the fixed frame 141 provides an installation base for the telescopic rod three 1423. The telescopic rod three 1423 pushes the push plate two 142 to slide in the fixed frame 141, so as to realize the pressing and fixing of the conveying roller 12 and the rubber layer 125 by the pressing plate 144 and subsequent operations, thereby ensuring a smooth replacement process of the rubber layer 125.

[0039] A movable opening 1451 is provided on one side of the movable plate 145 near the push plate 2 142, and a spring buffer 2 1424 is fixedly connected to the position of the outer wall of the push plate 2 142 corresponding to the movable opening 1451, and a movable block 1425 is fixedly connected to one end of the spring buffer 2 1424 near the movable opening 1451, and the movable block 1425 is slidingly connected to the inner wall of the movable opening 1451, and a spring 4 1426 with one end connected to the movable block 1425 is provided inside the movable opening 1451, and the top of the movable block 1425 passes through the movable opening 1451 and extends to the outside thereof, and the end of the movable block 1425 located outside the movable opening 1451 is fixedly connected to the connecting rod 143, and the two ends of the connecting rod 143 are hinged with push rod 2 1431.

[0040] By adopting the above technical solution, the movable opening 1451 of the movable plate 145 is the key to connecting the push plate 2 142 with its own movement. The spring buffer 2 1424 on the outer wall of the push plate 2 142 is connected to the movable block 1425. When the push plate 2 142 moves, the spring buffer 2 1424 drives the movable block 1425 to slide in the movable opening 1451. The spring 4 1426 in the movable opening 1451 provides a buffer and reset force for the movable block 1425. It can be compressed when encountering resistance to prevent components from being damaged by collision. The movable block 1425 passes through the movable opening 1451 and connects to the connecting rod 143, converting the linear motion of the push plate 2 142 into the swinging motion of the connecting rod 143. The push rod 2 1431 hinged at both ends of the connecting rod 143 plays a key role. When the 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, and then the push rod 1431 pushes the docking rod 1231 to open the flap 123, creating conditions for the fixation of the extension block 1251 and ensuring the continuity of the replacement process of the rubber layer 125.

[0041] The working principle and usage process of the embodiment of the present invention are as follows:

[0042] The unwinding shaft 124 is connected to the end plate 126 in a damped rotation manner. In the normal state, the flap 123 will be pushed and stuck at the opening, and the rubber layer 125 will be clamped at the same time. The extension block 1251 at the end of the rubber layer 125 will be clamped by the flap 123, and the rest of the end will be stuck in the position below the flap 123. Such clamping can reduce the protrusion caused by the rubber layer 125 being squeezed, thereby preventing it from affecting the paper conveying process. The extension block 1251 is located at the end of the roller body 121 and does not participate in the paper conveying. The auxiliary roller 11 is rotatably connected to the position above the conveying roller 12 inside the machine body 1, and the auxiliary roller 11 plays the role of pressing the paper.

[0043] by Figure 6 、 Figure 7For example, after the conveying roller 12 has been used for a certain period of time, the rubber layer 125 surrounding the surface of the conveying roller 12 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 frame 131 to rise. The rising of the mounting frame 131 will drive the retracting shaft 133 and the push rod 1371 to approach the conveying roller 12. The push rod 1371 will first be inserted into the docking port 1261 to dock with the docking rod 1231, and then continue to push the docking rod 1231 to rise. By pushing the docking rod 1231, the flap 123 is flipped open toward the inside of the roller body 121. 23 opens and loses its grip on the rubber layer 125, and the retracting shaft 133 will be close to the roller body 121. When the flap 123 is opened, the extension block 1251 will fall into the clamping opening 1331 due to gravity, and then the electromagnet 1333 is energized to pull the clamping plate 1334 to clamp the extension block 1251. Then the reeling mechanism 13 drops the push rod 1371 to disengage from the docking rod 1231 and drives the retracting shaft 133 to rotate through the driving motor. The rotation of the retracting shaft 133 will wind the discarded rubber layer 125 onto itself, and during winding, the rubber layer 125 will be pulled to make the conveying roller 12 rotate clockwise.

[0044] When the waste rubber layer 125 is completely separated from the roller body 121, the winding mechanism 13 rises and pushes the flap 123 open, and then the winding shaft 133 continues to rotate, and the new rubber layer 125 inside the roller body 121 is also wound around its outside. When the winding shaft 133 is wound until the rubber layer 125 can circle around the roller body 121 for one circle, it stops rotating, and then the winding mechanism 13 drops the push rod 1371 to disengage the docking rod 1231, and then the conveying roller 12 rotates counterclockwise to wrap the pulled out rubber layer 125 around itself once, and the telescopic rod 2 136 will push the push plate 135 and the cutter 134 to cut the rubber layer 125. After the blade of the cutter 134 cuts off the rubber layer 125, an extension block 1251 will be formed. Because the extension block 1251 is an extra part, after the rubber layer 125 circles once, the extension block 1251 will fall on the surface of the rubber layer 125.

[0045] When the rubber layer 125 is cut off, the opening of the conveying roller 12 is downward, and the conveying roller 12 rotates seventy degrees counterclockwise to align with the docking mechanism 14, and then the telescopic rod three 1423 will push the push plate two 142 to drive the pressure plate 144 to press on the surface of the conveying roller 12, and at the same time press the rubber layer 125 to be fixed. Because the pressure plate 144 cannot move after being connected to the conveying roller 12, the telescopic rod three 1423 continues to push the push plate two 142 to compress the spring three 1422, so the movement of the push plate two 142 will drive the connecting rod 143 and the movable plate 145 to move through the spring buffer two 1424 and the movable block 1425. At the same time, the push plate two 142 will also push the extrusion head 146 to move through the fixed rod 1461. During the movement, the push rod two 1431 hinged at both ends of the connecting rod 143 will first dock with the docking rod 1231 through the docking interface 1261, and then the push plate two 142 continues to push When the lever 144 is in the unlocked position, the second lever 1431 pushes the second lever 1431 to open the flap 123, and the extrusion plate 1452 of the movable plate 145 pushes the extension block 1251 into the inside of the bayonet through the through-hole 1442. After the extension block 1251 enters the bayonet, the movable plate 145 fits with the pressure plate 144. After fitting, the movable plate 145, the movable block 1425 and the connecting rod 143 cannot get close to the conveying roller 12, and the push plate 142 continues to push to squeeze the spring buffer 1424 to compress it, but the push plate 142 pushes the extrusion head 146 to continue moving through the fixed rod 1461. The movement of the extrusion head 146 will cause the movable plate 145 to move toward the end of the fixed frame 141 by squeezing the extrusion block 1453. The movement of the movable plate 145 will drive the extrusion plate 1452 to come out of the through-hole 1442 and the docking port 1261, thereby leaving the extension block 1251 inside the opening.

[0046] Then the telescopic rod 3 1423 pulls the push plate 2 142 to retract quickly, so that the push rod 2 1431 and the docking rod 1231 are quickly separated, so that the flap 123 quickly clamps and fixes the extension block 1251 and the rubber layer 125.

[0047] In summary, compared with the prior art, the embodiments of the present invention have the following advantages:

[0048] Advantage 1: The present invention utilizes the coordinated action of the unwinding shaft 124, flap 123, and rewinding mechanism 13 within the conveyor roller 12 to rapidly replace the rubber layer 125. When the rubber layer 125 wears out, there's no need to shut down the entire roller for replacement. The rewinding mechanism 13 simply rolls up the old rubber layer 125 and replaces it with a new one, significantly saving time and costs while improving production efficiency. This advantage is due to the ingenious design of the unwinding shaft 124 and flap 123, as well as the precise control of components within the rewinding mechanism 13, such as the electromagnet 1333 and clamping plate 1334.

[0049] Advantage 2: The design of the conveyor roller 12 effectively prevents paper slipping during transport. The rubber layer 125, tightly clamped by the flap 123 and the unwinding shaft 124, ensures its stability and uniformity on the roller body 121, thereby improving the accuracy and efficiency of paper transport. Furthermore, the provision of the auxiliary roller 11 further enhances paper transport stability, preventing paper deviation and wrinkling during transport.

[0050] Advantage 3: The structure of the conveyor roller 12 of the present invention reduces wear on the roller during long-term use by optimizing the fixing method of the rubber layer 125. The extension block 1251 at the end of the rubber layer 125 allows the rubber layer 125 to enter and exit the roller body 121 more smoothly during replacement, preventing excessive localized wear of the roller due to uneven friction. Furthermore, the flap 123 and spring buffer 1212 effectively cushion the impact of paper on the roller, further extending the roller's service life.

[0051] Advantage 4: The intelligent design of the winding mechanism 13 and docking mechanism 14 makes the replacement process of the rubber layer 125 more automated and convenient. The coordinated action of the electromagnet 1333, the first clamping plate 1334, and the first push rod 1371 enables automatic winding and securing of the rubber layer 125. The second push plate 142, the movable plate 145, and the extrusion head 146 of 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 operational safety and reliability.

[0052] Advantage 5: The stacking and forming assembly mechanism of the present invention effectively prevents damage to paper during conveying and stacking, such as scratches and wrinkles, by optimizing paper conveyance stability and accuracy, thereby improving paper quality. Furthermore, the rapid replacement and maintenance of the rubber layer 125 reduces the impact of roller aging on paper quality, ensuring a stable and consistent production process.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
