Description

Technical Field

[0001] This utility model relates to the field of paper binding equipment technology, specifically to a paper bonding mechanism. Background Technology

[0002] In the printing, packaging, and binding industries, paper bonding is a common processing technique widely used in the production of books, notebooks, photo albums, and other products. Traditional paper bonding methods mainly include manual gluing and mechanical gluing. Manual gluing is inefficient, results in uneven glue application, and easily leads to weak adhesion or glue overflow. While existing mechanical gluing equipment improves production efficiency, it still has shortcomings in terms of gluing precision, pressing effect, and degree of automation.

[0003] Currently, paper bonding equipment on the market typically uses fixed glue-applying rollers and pressing mechanisms. During the glue-applying process, it's difficult to flexibly adjust the glue amount according to paper thickness and bonding requirements. Furthermore, the glue-applying and pressing processes are often performed separately, resulting in low production efficiency. In addition, traditional equipment is prone to affecting bonding quality during pressing after glue application due to incomplete glue penetration or uneven pressure, even leading to paper misalignment or wrinkling.

[0004] To address the aforementioned problems, existing technologies have proposed several improvements, such as using liftable glue-applying rollers or adding a pressing mechanism to optimize the bonding effect. However, these solutions still have shortcomings in structural design, such as poor linkage between the glue-applying and pressing components, high risk of motion interference, and difficulty in ensuring glue uniformity. Utility Model Content

[0007] The glue application assembly includes a glue storage tray, a glue spreading roller, and a glue coating roller. The glue storage tray is slidably mounted on the mounting bracket. The glue storage tray and the pressure plate are linked together. The glue spreading roller and the glue coating roller are rotatably mounted on the glue storage tray and are poweredly connected. The glue coating roller is arranged directly below the clearance groove. The outer edge of the glue coating roller is evenly provided with glue storage grooves. The glue spreading roller is arranged between the glue coating roller and the glue storage tray.

[0008] Based on the above technical solutions, in order to ensure that the glue storage tray can be stably assembled on the mounting bracket in a relatively sliding posture, and to ensure that the glue spreading roller and the glue coating roller can be stably installed on the glue storage tray, the following technical solutions are provided.

[0009] The mounting bracket is provided with a vertically arranged lifting guide groove. The outer wall of the glue storage tray is fixed with a sliding seat that slides with the lifting guide groove. Both ends of the glue storage tray are fixed with upwardly extending connecting ear plates. Both ends of the glue spreading roller and the glue coating roller are rotatably mounted on the connecting ear plates. The same end of the glue spreading roller and the glue coating roller is fixed with a transmission gear that maintains a meshing connection.

[0010] Based on the above technical solutions, in order to ensure that the rubber spreading roller and the glue coating roller can operate stably and are not affected by the lifting posture of the glue coating component, the following technical solutions are provided.

[0011] It also includes a drive assembly, which includes a drive motor, a drive bevel gear A, a transmission bevel gear A, a drive bevel gear B, a transmission bevel gear B, and a spline shaft. The drive motor is fixedly mounted on the mounting bracket and the drive bevel gear A is fixedly connected to its output shaft. The transmission bevel gear A is rotatably mounted on the mounting bracket and meshes with the drive bevel gear A. The drive bevel gear B is rotatably mounted on the connecting lug plate and the spline shaft is fixedly connected to its shaft center. The spline shaft is slidably inserted with the transmission bevel gear A. The transmission bevel gear B is fixedly connected to the glue-applying roller and meshes with the drive bevel gear B.

[0012] Based on the above technical solutions, in order to ensure that the pressing assembly can drive the pressure plate to run stably in the horizontal direction and realize the linkage combination of the pressure plate and the glue storage tray, the following technical solutions are provided.

[0013] An assembly plate A is fixedly attached to the upper surface of the operating platform. Connecting wing plates with outward extensions are fixedly attached to both sides of the pressure plate. A guide rod A is fixedly attached to the back side of the pressure plate and is slidably inserted into the assembly plate A.

[0016] The beneficial effects of this utility model are: 1. The glue is applied evenly and the adhesion is strong. The structure of the glue roller and the glue applicator roller ensures that the glue is evenly applied to the glue storage tank of the glue applicator roller, so that the glue can accurately penetrate between multiple layers of paper, avoiding problems such as glue overflow or uneven application. It can also adapt to paper of different thicknesses, ensuring that the glue fully wets the paper layers and improves the bonding strength.

[0017] 2. The glue application and pressing are linked to improve production efficiency. The glue application and pressing components adopt a linked structure.

The drive component adopts spline shaft transmission, which enables the glue application roller to operate stably during the lifting process, avoiding power interruption or transmission failure.

[0019] 4. High degree of automation and convenient operation. The movement of the pressure plate and support plate is controlled by the telescopic cylinder, and the automatic feeding, gluing, pressing and unloading are achieved in conjunction with the transmission mechanism, reducing manual intervention and reducing the difficulty of operation. The automatic reset function of the gluing roller ensures that it returns to the initial position after each operation, which is convenient for continuous production.

[0020] 5. It is highly adaptable and has a wide range of applications. It can be adapted to paper of different thicknesses and materials, and is suitable for various scenarios such as bookbinding and packaging box gluing, meeting diverse production needs. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-7 A paper bonding mechanism includes a mounting bracket 1 and an adhesive application component 2, a pressing component 3, and a support component 4 mounted thereon. A horizontally arranged operating platform 11 is fixed to the mounting bracket 1. A clearance slot 12 is provided on the operating platform 11. The adhesive application component 2 is arranged below the operating platform 11 and moves up and down in the vertical direction. The pressing component 3 includes a pressure plate 31 arranged above the operating platform 11 and moving in the horizontal direction. The support component 4 includes a support plate 41 arranged vertically and moving up and down. The support plate 41 and the pressure plate 31 are respectively arranged on both sides of the clearance slot 12.

[0025] The glue application assembly 2 includes a glue storage tray 21, a glue spreading roller 22, and a glue application roller 23. The glue storage tray 21 is slidably mounted on the mounting bracket 1. The glue storage tray 21 and the pressure plate 31 are linked together. The glue spreading roller 22 and the glue application roller 23 are rotatably mounted on the glue storage tray 21 and are connected by power. The glue application roller 23 is arranged directly below the clearance groove 12. The outer edge of the glue application roller 23 is evenly provided with glue storage grooves 231. The glue spreading roller 22 is arranged between the glue application roller 23 and the glue storage tray 21.

[0026] The mounting bracket 1 ensures stable assembly and operation of all components, while the operating platform 11 provides a smooth working surface. In use, it needs to be used in conjunction with a clamping mechanism for holding multiple sheets of paper without displacement and a transport mechanism for transferring the clamping mechanism and the paper.

[0027] During the paper feeding stage, the support plate 41 in the control support assembly 4 is lowered below the operating platform 11 to avoid spatial movement interference with the paper being transported. Then, the clamping mechanism and the clamped paper are smoothly transported from one side of the support assembly 4 to the operating platform 11 through the transmission mechanism, and gradually pass through the clearance slot 12.

[0028] Then the gluing stage begins. At this time, the pressure plate 31 in the pressing assembly 3 is on the side away from the assembly, and the gluing assembly 2 is at the top of its stroke under the linkage with the pressure plate 31, and the top of the gluing roller 23 is above the operating platform 11 through the clearance groove 12.

[0029] Under the continuous operation of the glue-spreading roller 22, the glue stored in the glue storage tray 21 can be evenly coated onto it. With the cooperation of the glue-applying roller 23, the glue on the glue-spreading roller 22 can be transferred to the glue storage tank 231 provided on the glue-applying roller 23. As the multi-layered paper gradually passes through the glue-applying roller 23 containing glue, the tank wall of the glue storage tank 231 can open the stacked paper and apply glue between the adjacent sheets of paper.

[0030] After all the paper has passed through the glue roller 23, it enters the pressing stage. At this time, the support plate 41 in the control support assembly 4 is raised above the operating platform 11, and the transmission mechanism is controlled to drive the clamping mechanism and the stacked and glued paper to move towards the support plate 41. At the same time, the pressure plate 31 in the pressing assembly 3 is controlled to move towards the support plate 41, and the glued assembly 2 linked with the pressure plate 31 will automatically move vertically downward to separate the glued assembly 2 from the stacked paper and thus avoid repeated glue application to the paper.

[0031] As the pressure plate 31 moves toward the support plate 41, it can cooperate with the support plate 41 to press and shape the paper coated with glue between the two, thereby realizing the paper bonding and binding operation.

[0032] Then, the feeding stage begins. The support plate 41 moves downward to make way for the paper feeding path, while the pressure plate 31 moves in the opposite direction to the support plate 41 and resets. Under the linkage, the glue coating component 2 automatically rises to the top of its stroke. At this time, the glue-coated paper can be controlled to automatically feed in the reverse direction.

[0033] To ensure that the glue storage tray 21 can be stably assembled on the mounting bracket 1 in a relatively sliding posture, and to ensure that the glue spreading roller 22 and the glue coating roller 23 can be stably installed on the glue storage tray 21, the following technical solutions are provided.

[0034] The mounting bracket 1 has a vertically arranged lifting guide groove 13. The outer wall of the glue storage tray 21 is fixed with a sliding seat 211 that maintains a sliding combination with the lifting guide groove 13. Both ends of the glue storage tray 21 are fixed with upwardly extending connecting ear plates 212. The two ends of the glue spreading roller 22 and the glue coating roller 23 are rotatably mounted on the connecting ear plates 212. The same end of the glue spreading roller 22 and the glue coating roller 23 are fixed with a transmission gear 24 that maintains a meshing connection.

[0035] The cooperation between the lifting guide groove 13 and the sliding seat 211 can ensure that the glue storage tray 21 can be raised and lowered stably in the vertical direction, while the setting of the connecting ear plate 212 can ensure that the glue spreading roller 22 and the glue coating roller 23 are stably installed on the glue storage tray 21 in a relative rotation manner, and then the glue in the glue storage tray 21 is evenly transferred to the glue coating roller 23 under the action of the glue spreading roller 22.

[0036] The transmission gear 24 is designed to ensure that the glue-spreading roller 22 and the glue-applying roller 23 always maintain the same speed and reverse rotation, thereby ensuring that the glue-spreading roller 22 can stably transfer the glue onto the glue-applying roller 23.

[0037] To ensure that the adhesive roller 22 and the adhesive coating roller 23 can operate stably and are not affected by the lifting posture of the adhesive coating assembly 2, the following technical solution is provided.

[0038] It also includes a drive assembly 5, which includes a drive motor 51, a drive bevel gear A52, a transmission bevel gear A53, a drive bevel gear B54, a transmission bevel gear B55, and a spline shaft 56. The drive motor 51 is fixedly mounted on the mounting bracket 1 and the drive bevel gear A52 is fixedly connected to its output shaft. The transmission bevel gear A53 is rotatably mounted on the mounting bracket 1 and meshes with the drive bevel gear A52. The drive bevel gear B54 is rotatably mounted on the connecting ear plate 212 and the spline shaft 56 is fixedly connected to its shaft center. The spline shaft 56 and the transmission bevel gear A53 are slidably inserted into each other. The transmission bevel gear B55 is fixedly connected to the glue application roller 23 and meshes with the drive bevel gear B54.

[0039] The drive motor 51 is fixedly mounted on the mounting bracket 1, which will not interfere with the lifting and lowering movement of the glue application assembly 2, nor will it affect the weight distribution of the glue application assembly 2. When the drive motor 51 is working, it can drive the drive bevel gear A52 to rotate, thereby driving the transmission bevel gear A53 and the spline shaft 56 to rotate stably.

[0040] During the lifting and lowering motion of the glue application assembly 2, the drive bevel gear B54, transmission bevel gear B55, and spline shaft 56 can be driven to lift and lower synchronously. Since the spline shaft 56 always maintains a sliding connection with the transmission bevel gear A53, the power of the transmission bevel gear A53 can always drive the drive bevel gear B54 through the spline shaft 56, and then drive the glue application roller 23 to operate stably through the transmission bevel gear B55.

[0041] To ensure that the pressing assembly 3 can drive the pressure plate 31 to run stably in the horizontal direction and realize the linkage between the pressure plate 31 and the glue storage tray 21, the following technical solution is provided.

[0042] An assembly plate A14 is fixedly attached to the upper surface of the operating platform 11. Connecting wing plates 311 with outward folding are fixedly attached to both sides of the pressure plate 31. A guide rod A312 that is slidably inserted into the assembly plate A14 is fixedly attached to the back side of the pressure plate 31. The pressing assembly 3 also includes a telescopic cylinder A32 and a connecting rod 33. The telescopic cylinder A32 is fixedly installed on the assembly plate A14 and its movable end is fixedly connected to the pressure plate 31. Connecting rods 33 are arranged on both sides of the pressure plate 31. The two ends of the connecting rods 33 are respectively hinged to the connecting wing plate 311 and the glue storage tray 21.

[0043] Connectors 213 are fixedly installed on both sides of the bottom of the glue storage tray 21. The bottom end of the connecting rod 33 is hinged to the connector 213, and the connecting wing plate 311 can realize the hinged combination of the pressure plate 31 and the connecting rod 33.

[0044] The guide rod A312 provides guidance for the pressure plate 31, enabling the pressure plate 31 to run stably in the horizontal direction. During the telescopic movement of the telescopic cylinder A32, it can drive the pressure plate 31 to slide stably. When the pressure plate 31 is telescopic, it can be linked with the glue storage tray 21 through the connecting rod 33, thereby driving the glue storage tray 21 to achieve the corresponding lifting and lowering movement.

[0045] To ensure that the support component 4 can drive the support plate 41 to operate stably along the water flow direction, the following technical solution is provided.

[0046] The operating platform 11 is provided with a telescopic slot 15, which is slidably inserted into the support plate 41. An assembly plate B16 is fixedly connected to the lower surface of the operating platform 11. A guide rod B411 is fixedly connected to the bottom of the support plate 41 and is slidably inserted into the assembly plate B16. The support assembly 4 also includes a telescopic cylinder B42 fixedly installed on the assembly plate B16. The movable end of the telescopic cylinder B42 is fixedly connected to the support plate 41.

[0047] Both the assembly plate B16 and the support plate 41 are equipped with L-shaped structures to ensure that the telescopic cylinder B42 and the guide rod B411 are stably arranged and matched. The arrangement of the telescopic slot 15 ensures that the support plate 41 can be raised and lowered on the operating platform 11. The cooperation between the guide rod and the assembly plate B16 enables the support plate 41 to be raised and lowered stably in the vertical direction.
