Description

Technical Field

[0001] This utility model relates to the field of paper coating technology, and in particular to a coating equipment for paper coating. Background Technology

[0002] A laminating machine, also known as a sealing machine or sealing press, is a specialized piece of equipment that uses rolling heating to generate high temperatures to shape hot-melt adhesive films and flat objects, including documents, photos, and drawings. For some papers printed with various patterns or colors, to increase the gloss of the printed paper and protect the ink from blurring, a plastic film coated with adhesive is heated and bonded to the printed paper, forming a paper-plastic composite laminated product. Laminated paper prints not only have improved gloss and durability but also extended their lifespan.

[0003] Because multiple sheets of paper are laminated together, each sheet needs to be glued. During feeding, some sheets may stick together, preventing some from being glued and requiring them to be separated and re-glued, thus affecting efficiency. Furthermore, the support rollers used for gluing, after a certain period of use, require thorough cleaning of the glue surface when changing to a different glue to prevent sticking. Currently, the support rollers are fixed inside the gluing machine via a transmission mechanism, requiring numerous screws to be unscrewed during disassembly, which is extremely inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a gluing device for paper sheet coating, addressing the shortcomings of existing technologies.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A gluing device for coating paper includes a gluing frame, which is provided with a paper stacking station, a paper feeding mechanism and a paper gluing mechanism.

[0007] The paper feeding mechanism includes a longitudinally movable adsorption rod, with multiple adsorption modules arranged along the length of the adsorption rod, and also includes multiple spaced separation structures, each including a separation spring and a separation spring, which respectively contact and cooperate with the rising paper.

[0008] The paper gluing mechanism includes a gluing roller and a support module that cooperates with the gluing roller. The support module includes a support roller that is spaced apart from the gluing roller and a support seat that provides movable support for the support roller. The gluing roller is equipped with a first drive gear, and the support roller is equipped with a second drive gear that meshes with the first drive gear. The support module also includes a bottom lifting mechanism that drives the support seat to move longitudinally closer to or away from the gluing roller.

[0009] The beneficial effects of this utility model are as follows: the adsorption module installed on the adsorption rod descends to adhere to the paper and then adsorbs it. Subsequently, the adsorption rod rises to feed the paper. During the feeding process, the separation spring and separation sheet of the separation structure contact and cooperate with the rising paper. Since the separation sheet of the separation spring will separate multiple overlapping sheets of paper, the multiple sheets of paper that are stuck together can be separated, preventing the paper from being over-adhesive when feeding.

[0010] The gluing roller and the support roller rotate synchronously through the meshing transmission of the first drive gear and the second drive gear. When the support roller needs to be disassembled, the bottom lifting mechanism can drive the support seat to move longitudinally closer to or away from the gluing roller. The second drive gear installed on the support roller can be separated from the first drive gear. Since the support seat provides movable support for the support roller, the support roller can be pulled out from the support seat. The support roller can be separated from the gluing roller. After being pulled out, the support roller can be cleaned. Disassembly can be achieved without removing screws, which is more efficient and facilitates subsequent installation.

[0048] The present invention will now be described in detail with reference to the accompanying drawings.

[0049] like Figures 1-9 As shown, a gluing device for coating paper includes a gluing frame 100, which is provided with a paper stacking station 101, a paper feeding mechanism 102 for adsorbing and feeding paper, and a paper gluing mechanism 103 for coating paper with glue.

[0050] The laminating frame includes a pair of parallel, spaced-apart guide plates 2.

[0051] The paper stacking station 101 is equipped with a feeding plate 5 for stacking paper. The feeding plate 5 is equipped with multiple horizontally arranged adjustment slots 51, and positioning rods 52 are inserted vertically into the adjustment slots 51. Multiple stacks of paper are placed in the paper stacking station 101, and the paper feeding mechanism 102 picks up and feeds the paper one by one to the paper gluing mechanism 103.

[0052] The feeding plate 5 can be raised and lowered by a power device such as a lifting cylinder. Each time a sheet of paper is fed, the feeding plate 5 rises by the thickness of one sheet of paper to ensure that the paper feeding mechanism 102 can contact the top sheet of paper and adsorb it when it descends. The feeding plate 5 is provided with multiple horizontally arranged adjustment slots 51. A positioning rod 52 is inserted vertically into the adjustment slot 51. The positioning rod 52 can move along the length of the adjustment slot 51. The positioning rod 52 can position the stacked paper to prevent the paper from shifting laterally and ensure the adsorption stability during feeding.

[0053] Preferably, the feeding plate 5 is positioned between the two guide plates 2. The paper stacking station 101 is also provided with a distance adjustment mechanism below the feeding plate 5. The distance adjustment mechanism includes a guide shaft 53 and a drive screw 54 installed between the two guide plates 2. The guide shaft 53 and the drive screw 54 are arranged in parallel and spaced apart. A bottom adjustment plate 55 is slidably mounted on the guide shaft 53. The bottom adjustment plate 55 is equipped with a screw sleeve seat that is in transmission cooperation with the drive screw 54. The bottom of the positioning rod 52 is installed on the bottom adjustment plate 55. By rotating the drive screw 54, the bottom adjustment plate 55 can move along the length direction of the guide shaft 53 to adjust the position of the positioning rod 52. The positioning rod 52 can move along the adjustment groove 51 to position papers of different sizes and prevent the paper from shifting laterally.

[0054] Preferably, one of the guide plates 2 is provided with a longitudinally arranged adjusting track 56, and a longitudinal moving seat 57 is slidably installed on the adjusting track 56. The longitudinal moving seat 57 is connected to the feeding plate 5. The guide plate 2 is also longitudinally arranged with a chain drive module 58. One of the long sides of the chain drive module 58 is connected to the longitudinal moving seat 57. The chain drive module 58 moves under the drive of a motor, thereby driving the longitudinal moving seat 57 to move up and down along the adjusting track 56. For each sheet of paper fed into the feeding plate 5, the feeding plate 5 rises by the thickness of one sheet of paper to ensure that when the paper feeding mechanism 102 descends to the corresponding height to adsorb the paper, the paper feeding mechanism 102 can contact the topmost sheet of paper and adsorb it.

[0055] The paper feeding mechanism 102 includes an adsorption rod 21 that can move longitudinally. The adsorption rod 21 has multiple adsorption modules 38 arranged along its length. It also includes multiple spaced separation structures 10. The separation structure 10 includes a separation spring 13 and a separation spring 16. The separation spring 16 and the separation spring 13 respectively contact and cooperate with the rising paper.

[0056] The adsorption module 38 installed on the adsorption rod 21 descends to adsorb the paper stacking position, and then the adsorption rod 21 rises to feed the paper. During the feeding process, the separation spring 16 and the separation spring 13 of the separation structure 10 contact and cooperate with the rising paper. Since the separation spring 16 and the separation spring 13 will separate multiple overlapping papers, the multiple sticky papers can be separated to prevent the sticky papers from being over-glueed during feeding.

[0057] Specifically, the paper feeding mechanism 102 also includes guide plates 2 installed at both ends of the adsorption rod 21. The guide plates 2 have an installation function and provide support for the overall structure. The guide plates 2 are formed with longitudinal grooves 22. When the adsorption rod 21 moves longitudinally, it will move under the limit of the longitudinal grooves 22. Driven by the power mechanism, the adsorption rod 21 moves up and down along the length of the longitudinal grooves 22, thereby realizing the lifting and feeding of paper.

[0058] The paper feeding mechanism 102 also includes a paper pressing structure for pressing down the stacked papers. The paper pressing structure includes a rotatable paper pressing shaft 18, which is installed between two guide plates 2 and can rotate in the guide plates 2. Multiple paper pressing pieces 19 are installed on the paper pressing shaft 18 along its length. When the paper pressing shaft 18 rotates, the paper pressing pieces 19 installed on the paper pressing shaft 18 can swing. When swinging downward, they can press down and position the stacked papers to prevent the papers from bouncing up.

[0059] Furthermore, the paper feeding mechanism 102 also includes a side plate 1 for mounting the separation structure 10. Multiple separation structures 10 are arranged at intervals along the length of the side plate 1. The side plate 1 also has a paper pressing groove 17 for the paper pressing sheet 19 to pass through. The paper pressing shaft 18 is located on the back of the side plate 1. The paper pressing groove 17 allows the paper pressing sheet 19 to swing. When pressing paper, the paper pressing shaft 18 rotates, so that the paper pressing sheet 19 can swing. When swinging downward, it can press down the stacked paper. When the paper pressing shaft 18 rotates in the opposite direction, the paper pressing sheet 19 can swing upward. At this time, the paper pressing sheet 19 is away from the stacked paper, and the paper can be adsorbed and fed by the adsorption module 38.

[0060] Furthermore, the separation structure 10 also includes a first mounting groove 11 and a second mounting groove 12 disposed on the upright plate. The separation spring 13 includes a spring body mounted on the second mounting groove 12. The outer end of the spring body is formed with a first spring 14 and a second spring 15 arranged at intervals. The separation spring 16 is located at the top of the separation spring 13 and is a compression spring. The separation spring 16 and the separation spring 13 disposed on the side upright plate 1 respectively contact the paper being adsorbed and raised. The paper passes through the first spring 14, the second spring 15 and the separation spring 16 in sequence. If the paper sticks together, the first spring 14, the second spring 15 and the separation spring 16 will release the sticky paper under elastic action to separate it, preventing more than two sheets of paper from being fed at the same time.

[0061] The separation springs 16 and separation tabs 13, arranged at intervals, function like multiple anti-sticking structures. The lower separation tab 13 contacts the paper first, separating any stuck sheets. As the paper rises, it contacts the separation springs 16, which continue to elastically contact the paper. If multiple sheets still stick together, the separation springs 16 can separate them, preventing more than one sheet from being fed simultaneously. These multiple anti-sticking structures work sequentially to ensure that the paper does not stick during feeding.

[0062] The adsorption rod 21 is connected to movable plates 24 at both ends. The guide plate 2 has a transverse track 49 for the transverse movement of the movable plate 24, and a longitudinal track 39 for the longitudinal movement of the adsorption rod 21. When the adsorption rod 21 moves up and down, it will move up and down along the longitudinal track 39, which has a limiting function. The adsorption rod 21 is fixedly fitted with fixing strips 27 at both ends. The movable plate 24 is formed with a guide track 25 for guiding the movement of the fixing strips 27. Multiple guide protrusions 26 are provided along the guide track 25. When the adsorption rod 21 moves up and down along the longitudinal groove 22 of the guide plate 2, the bottom end of the fixing strip 27 fitted on the adsorption rod 21 will roll in cooperation with the guide track 25. When it passes the guide protrusions 26, the angle of the fixing strip 27 changes. Since the adsorption rod 21 is fixedly installed on the fixing strip 27, the adsorption rod 21 will swing, which can shake off the stuck paper and prevent multiple sheets of paper from sticking together.

[0063] It should be noted that a swing guide wheel 28 is installed at the bottom of the fixing strip 27, which rolls in cooperation with the guide rail 25. When the suction rod 21 moves up and down, the swing guide wheel 28 installed on the fixing strip 27 will roll along the guide rail 25; there are two guide protrusions 26. When the suction rod 21 moves longitudinally down to the bottom and adsorbs the paper, the suction rod 21 rises. At this time, when the swing guide wheel 28 rolls in cooperation with the bottom guide protrusion 26, the bottom end of the fixing strip 27 swings inward, and the suction rod 21 swings inward simultaneously. At this time, the inner edge of the paper will be brought into contact with the separation structure 10, and then in sequence with the separation spring 13 and the separation spring 16. Under the action of the separation spring 16 and the separation spring 13, if the rising paper is stuck together, it will be separated to prevent sticking. This allows the paper to better contact the separation structure 10.

[0064] Furthermore, the longitudinal chute 22 provides more space for the suction rod 21 to move than the outer track. A transverse movable groove 23 is formed at the bottom of the longitudinal chute 22, allowing the suction rod 21 to retract partially after reaching the bottom. After the suction rod 21 moves to the bottom along the longitudinal chute 22, the suction module 38 installed on the suction rod 21 adsorbs the topmost stacked paper. Then, the movable plate 24 retracts partially, causing the suction rod 21 to move outwards. At this point, the topmost paper is bent and arched, utilizing its rigidity to create an arc shape and elastically separate the upper and lower sheets, facilitating better separation from the second sheet and reducing the probability of multiple sheets sticking together.

[0065] The guide plate 2 is also equipped with a feeding guide block 29 located on the outer periphery of the top of the longitudinal chute 22. The feeding guide block 29 is fitted with horizontally arranged screws. The feeding guide block 29 is in contact with the top of the fixing strip 27 through the screws. The feeding guide block 29 can drive the lower half of the fixing strip 27 to swing inward in the direction of paper movement. When the adsorption rod 21 moves to the top along the longitudinal chute 22, the fixing strip 27 fitted on the adsorption rod 21 will swing inward. At this time, the paper adsorbed by the adsorption module 38 will be brought into the gluing station to better connect with the next mechanism, provide the best feeding position, and prevent the paper from falling off.

[0066] Specifically, the paper feeding mechanism 102 includes a first drive structure 3, a second drive structure 34, and a third drive structure 4 mounted on the guide plate 2. The first drive structure 3 can drive the suction rod 21 to move longitudinally; the second drive structure 34 can drive the movable plate 24 to move laterally; and the third drive structure 4 can drive the paper pressing shaft 18 to rotate. The feeding drive mechanism also includes a rotatable drive shaft 44, on which a first drive cam 45, a second drive cam 46, and a third drive cam 47 are coaxially sleeved. The first drive cam 45 is in rolling engagement with the drive end of the first drive structure 3; the second drive cam 46 is in rolling engagement with the drive end of the second drive structure 34; and the third drive cam 47 is in rolling engagement with the drive end of the third drive structure 4.

[0067] Specifically, the first drive structure 3 includes a first drive rod 31 and a first drive swing arm 32 connected to the first drive rod 31; the second drive structure 34 includes a second drive rod 35 and a second drive swing arm 36 connected to the second drive rod 35; one end of the first drive swing arm 32 and the second drive swing arm 36 are coaxially rotatably mounted on the guide plate 2; the top of the first drive rod 31 is connected to the suction rod 21; the top of the second drive rod 35 is connected to the paper pressing shaft 18; wherein the first drive swing arm 32 is equipped with a first drive roller 33 that rolls with the first drive cam 45; the second drive swing arm 36 is equipped with a second drive roller 37 that rolls with the second drive cam 46; when the drive shaft 44 rotates, the first drive cam 45 rolls with the first drive roller 33 of the first drive structure 3; the second drive cam 46 rolls with the second drive roller 37 of the second drive structure 34; and the third drive cam 47 rolls with the third drive roller 42 of the third drive structure 4.

[0068] It should be noted that the guide plate 2 is also equipped with multiple tension springs arranged longitudinally. One tension spring is connected to the top of the first drive arm 32, and another tension spring is connected to the second drive arm 36. When the first drive arm 32 is not subjected to the lifting force of the first drive cam 45, the tension spring will pull the first drive arm 32 downward to return to its original position. Similarly, when the second drive arm 36 is not subjected to the lifting force of the second drive cam 45, the tension spring will pull the first drive arm 32 downward to return to its original position.

[0069] Specifically, the protruding part of the first drive cam 45 and the protruding part of the second drive cam 46 form an angle. Therefore, when the protruding part of the first drive cam 45 engages with the first drive roller 33, the suction rod 21 is located at the top of the longitudinal groove 22. The protruding part of the second drive cam 46 does not contact the second drive roller 37. Under the action of gravity, the second drive structure 34 will press down the paper pressing piece 19 to press down on the paper. Conversely, when the protruding part of the first drive cam 45 does not engage with the first drive roller 33, the suction rod 21 is located at the bottom of the longitudinal groove 22. The protruding part of the second drive cam 46 contacts the second drive roller 37. Under the action of the second drive cam 46, the second drive structure 34 will swing the paper pressing shaft 18, and the paper pressing piece 19 will move away from the paper. At this time, the paper can be suctioned and lifted longitudinally.

[0070] The third drive structure 4 includes a lever 41 rotatably mounted on the guide plate 2. A third drive roller 42 that rolls with the third drive cam 47 is mounted at the bottom of the lever 41. A top drive roller 43 that rolls with the movable plate 24 is mounted at the top of the lever 41. The third drive cam 47 is generally a disc structure with an inwardly concave arc groove 48 formed at its edge. The inwardly concave arc groove 48 engages with the protruding part of the first drive cam 45.

[0071] It should be noted that one or more tension springs are arranged laterally and are connected to the movable plate 24. When the movable plate 24 is not subjected to the force of the top drive roller 43 of the lever 41, these tension springs will pull the movable plate 24 back to achieve the return to its original position.

[0072] When the adsorption rod 21 is located at the top of the longitudinal slide groove 22, the concave part of the third drive cam 47 does not contact the lever 41. At this time, under the action of the third drive cam 47, the lever 41 will move laterally inward a part, allowing the paper to further cooperate with the gluing station. At the same time, the feed guide block 29 contacts and cooperates with the top of the fixing strip 27 sleeved on the adsorption shaft. The fixing strip 27 sleeved on the adsorption rod 21 will swing inward. At this time, the paper adsorbed by the adsorption module 38 will be brought into the gluing station to better connect with the next mechanism and prevent the paper from falling from here.

[0073] Conversely, when the adsorption rod 21 is at the bottom of the longitudinal slide 22, the concave part of the third drive cam 47 rolls into contact with the third drive roller 42 of the lever 41. At this time, the movable plate 24 will be pulled back under the elastic action, and the movable plate 24 will move away from the paper feeding direction. Then, the adsorption rod 21 will continue to retract a part after moving to the bottom. After the adsorption rod 21 moves to the bottom along the longitudinal slide 22, the adsorption module 38 installed on the adsorption rod 21 adsorbs the topmost stacked paper. Then the movable plate 24 will retract a part, and the adsorption rod 21 will move outward a part. At this time, the topmost paper will be bent and arched a part to better separate from the second paper and reduce the probability of multiple papers sticking together.

[0074] In summary, a multi-layered anti-adhesion structure is adopted. The first layer involves the adsorption module 38 retracting slightly after adsorbing the topmost piece of paper, causing the topmost piece of paper to bend and arch, at which point the paper can be separated.

[0075] The second and third structures involve the paper being attracted and then rising to the next station. During the rising process, the suction rod 21 will swing. When it swings towards the side plate 1, the paper will sequentially engage with the separation spring 13 and the separation spring 16 of the separation structure 10. If there is still paper overlap at this time, the separation spring 13 and the separation spring 16 will sequentially separate the paper.

[0076] The paper laminating mechanism 103 includes a paper feeding station and a laminating station.

[0077] The paper feeding station includes a belt drive mechanism for forward conveying of paper. Above the belt drive mechanism is a guide roller to prevent the paper from tilting. The guide roller works in conjunction with the adsorption module. During feeding, the paper can be advanced into the gap between the guide roller and the belt drive mechanism. With the cooperation of the guide roller and the belt drive mechanism, the paper can advance to the gluing station.

[0078] The gluing station includes a gluing roller 61 and an adjusting roller 7 arranged with a gap between the gluing roller 61 and the gluing roller 61. The size of the gap between the adjusting roller 7 and the gluing roller 61 can adjust the thickness of the glue, thereby adjusting the thickness of the paper when it is coated with glue.

[0079] The glue-applying roller 61 is installed between two guide plates 2. The glue-applying station also includes a support module 6 that cooperates with the glue-applying roller 61. The support module 6 includes a support roller 63 that is spaced apart from the glue-applying roller 61 and a support seat 82 that provides movable support for the support roller 63. The glue-applying roller 61 is equipped with a first drive gear 62, and the support roller 63 is equipped with a second drive gear 67 that meshes with the first drive gear 62. The support module 6 also includes a bottom lifting mechanism 8 that drives the support seat 82 to move longitudinally closer to or away from the glue-applying roller 61.

[0080] The glue-coating roller 61 and the support roller 63 rotate synchronously through the meshing transmission of the first drive gear 62 and the second drive gear 67. When disassembly is required, the bottom lifting mechanism 8 can drive the support seat 82 to move longitudinally closer to or away from the glue-coating roller 61. The second drive gear 67 installed on the support roller 63 can be separated from the first drive gear 62. Since the support seat 82 provides movable support for the support roller 63, the support roller 63 can be pulled out from the support seat 82. The support roller 63 can be separated from the glue-coating roller 61. After being pulled out, the support roller 63 can be cleaned. Disassembly can be achieved without removing screws, which is more efficient and facilitates subsequent installation.

[0081] Furthermore, the bottom lifting mechanism 8 includes a longitudinally arranged support rod 81, the top of which is connected to a support base 82, and the support rod 81 is capable of longitudinal movement. The bottom lifting mechanism 8 also includes a drive base 85, which has a guide hole 86 for the longitudinal movement of the support rod 81. A guide sleeve 87 is installed in the guide hole 86, and the support rod 81 can move axially along the guide hole 86 where the guide sleeve 87 is installed, thereby driving the support base 82 installed on the top of the support rod 81 to move up and down. The second drive gear 67 installed on the support roller 63 can be disengaged or engaged with the first drive gear 62. After disengagement, the support roller 63 can be directly pulled out from the support base 82 for direct disassembly and cleaning; after cleaning, the support roller 63 is reinstalled on the support base 82, and then the support base 82 is raised. The second drive gear 67 installed on the support roller 63 can then engage with the first drive gear 62 for transmission, continuing the glue application process, greatly improving the efficiency of disassembly and cleaning.

[0082] Specifically, the bottom lifting mechanism 8 also includes a rotatable rotating shaft 9, on which a drive cam 91 is fitted. A drive plate 92 is mounted on the bottom of the support rod 81, and the drive cam 91 and drive plate 92 are in rolling engagement. When the rotating shaft 9 rotates, the drive cam 91 rotates. When the protruding part of the drive cam 91 faces downward, it drives the drive plate 92 mounted on the bottom of the support rod 81 to descend. At this time, the support seat 82 connected to the support rod 81 descends synchronously, thereby separating the second drive gear 67 from the first drive gear 62. Disengaging from the transmission, the support roller 63 can then be detached from the support seat 82 without the need for screws, thus greatly improving efficiency.

[0083] A compression spring 88 is sleeved on the support rod 81 between the support base 82 and the drive base 85. The elastic force of the compression spring 88 can drive the support base 82 to approach the glue roller 61. The compression spring 88 can drive the support rod 81 to rise elastically as a whole. When the rotating shaft 9 rotates, the drive cam 91 rotates. When the protrusion of the drive cam 91 faces upward, the drive plate 92 will not be subjected to the force of the drive cam 91. At this time, it will be subjected to the elastic force of the compression spring 88 and rise as a whole. The second drive gear 67 installed on the support base 82 maintains meshing with the first drive gear 62 to realize the glue application of the paper.

[0084] The bottom lifting mechanism 8 also includes a tension spring connected to the drive plate 92 at the bottom. The top of the tension spring is fixed. When the drive plate 92 is not subjected to the force of the drive cam 91, the tension spring can drive the drive plate 92 to lift elastically, so that the support seat 82 installed on the top of the support rod 81 can maintain support for the support roller 63.

[0085] Furthermore, a drive handle 93 is sleeved on the outer end of the rotating shaft 9. By swinging the drive handle 93, the rotating shaft 9 can rotate, and the drive cam 91 rotates to drive the drive plate 92 to descend, so that the support module 6 descends as a whole.

[0086] In one embodiment, the bottom lifting mechanism 8 also includes a lever module, which includes a fulcrum shaft and a lever component mounted on the fulcrum shaft. The driving end of the lever component extends outward and is connected to a driving handle. The driven end of the lever component cooperates with the driving plate 92. The driven end of the lever component is located at the top of the driving plate 92. When the driven section of the lever component is driven to swing vertically downward by the driving handle, the support module 6 can be lowered as a whole. At this time, the support roller 63 can be removed from the support seat 82 to complete disassembly and cleaning.

[0087] In one embodiment, the guide plate 2 has a through-hole groove 89 for the support rollers 63 to pass through; there are two support rollers 63, which are installed alternately on the top of the support base 82. The through-hole groove 89 is designed so that the support rollers 63 can be directly removed during disassembly. The two support rollers 63 form an arc-shaped support structure. After the paper passes through the first support roller 63, it continues to pass through the second support roller 63. The two support rollers 63 support the paper simultaneously, increasing the contact area between the paper and the gluing roller 61. During gluing, some gravure paper can be coated with more glue, increasing the coating area, ensuring the quality of gluing, and preventing glue shortages in the glued paper.

[0088] Specifically, the support roller 63 includes a roller shaft 64 and a roller body 65 sleeved on the roller shaft 64. The support base 82 is formed with a concave rotating groove 83, within which the roller shaft 64 rotates. A pull ring 96 is installed at the outer end of the roller shaft 64. A bearing seat 66 is sleeved on the roller shaft 64, and the support base 82 is formed with a bearing groove 84 for mounting the bearing seat 66, which communicates with the rotating groove 83. When the support roller 63 rotates via the roller shaft 64, the bearing seat 66 rotates and engages with the bearing groove 84, while the roller shaft 64 also rotates and engages with the rotating groove 83. This provides rotational and movable support for the support roller 63 via the support base 82, preventing it from becoming fixed. During disassembly, the support roller 63 can be easily separated from the support base 82, greatly improving the efficiency of disassembly and assembly.

[0089] Furthermore, the guide plate 2 is equipped with a longitudinally arranged, rotatable adjusting rod 94, and the drive seat 85 is formed with an adjusting hole 95 through which the adjusting rod 94 moves. The bottom of the adjusting rod 94 is connected to the drive plate 92. The adjusting hole 95 is a threaded hole, and the adjusting rod 94 is formed with an external thread structure that mates with the threaded hole. When the adjusting rod 94 is rotated, it engages with the adjusting hole 95 of the drive seat 85. The height of the adjusting rod 94 is adjustable. The top of the tension spring is fixed to the guide plate 2. When the protrusion of the drive cam 91 is facing upward, the drive plate 92 is not subjected to the force of the drive cam 91, but is subjected to the tension of the tension spring. The drive plate 92 is elastically lifted, and the second drive gear 67 mounted on the support seat 82 maintains meshing with the first drive gear 62. Then, the adjusting rod 94 is rotated to lift the drive plate 92. The drive plate 92 and the support seat 82 can be kept at the same height to prevent the compression spring 88 from loosening. This ensures that the support roller 63 located on the support seat 82 can maintain meshing with the glue roller 61 to stably apply glue to the paper.
