Description

Technical Field

[0002] The printing surface coating and pasting device is a key piece of equipment used in the post-printing processing field. Its core function is to apply plastic film to the surface of printed materials through gluing, pressing, and cutting to improve the gloss, wear resistance, and service life of the printed materials. Through industrial integration design, this device is applied in the publishing, packaging, and advertising industries and is the core equipment for realizing mass surface treatment of printed materials. From the perspective of industry development, its technical level directly affects the upper limit of the quality of printed materials and production efficiency. Therefore, the structural optimization and performance improvement of the equipment has always been an important direction for industry innovation.

[0003] Early laminating devices consisted of a mechanically driven fixed coating roller, a rigid pressing roller, and a manual cutting mechanism. Because the coating roller and the pressing roller were fixed to the frame using a traditional key connection, disassembling the roller required disassembling multiple components simultaneously, resulting in long cleaning and maintenance times and severely impacting production continuity. To improve maintenance efficiency, existing devices have replaced some key connections with quick-release flanges, simplifying the roller disassembly process to simply loosening the locking bolts and pulling it out. However, these improvements have not completely eliminated the traditional connection logic. The transmission ends of the core coating roller and the pressing roller still rely on keyways to transmit torque, requiring the transmission-side bearing housing and gearbox to be completely disassembled. Furthermore, during cleaning, the external structure must be removed before the roller can be taken out for cleaning, resulting in long processing times, complex operations, and inconvenience for disassembling and cleaning the equipment.

Detailed Implementation

[0031] 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.

[0032] Reference Figure 1 and Figure 2This utility model provides an embodiment of a printing surface coating and pasting device, comprising a base plate 1, with load-bearing brackets 3 fixedly connected to the top left and right ends of the base plate 1 for supporting and fixing pressure rollers 8. A fixing block 4 is rotatably connected to the top of the load-bearing brackets 3, providing necessary support and limiting structure for the rotation of the pressure rollers 8. A motor 5 is fixedly connected to the middle of the top left end of the base plate 1, providing power to the pressure rollers 8. A gear 6 is fixedly connected to the output end of the motor 5 to realize the transmission of rotational power. A gear 7 is meshed with the outer wall of the gear 6, realizing the transmission of power and the conversion of speed. A pressure roller 8 is fixedly connected to the inner wall of the gear 7, realizing the rotation of the pressure roller 8. The left and right ends of the outer wall of the pressure roller 8 respectively engage with the inner walls of the corresponding load-bearing brackets 3, enhancing the stability of the pressure roller 8 installation. Grooved blocks 9 are fixedly connected to the left and right sides of the base plate 1, providing sliding tracks for movable U-shaped brackets 10. The inner walls of the two grooved blocks 9 are slidably connected... There is a movable U-shaped bracket 10 for installing and supporting the laminating roller 11. The inner walls of the two movable U-shaped brackets 10 are each equipped with a laminating roller 11, which is used to cover the surface of the printed material with laminating material. The left and right sides of the outer wall of the laminating roller 11 are engaged with the inner walls of the corresponding movable U-shaped brackets 10 to ensure the stability of the laminating roller 11 within the movable U-shaped brackets 10. The front and rear sides of the outer walls of the two movable U-shaped brackets 10 are fixedly connected with electric telescopic rods 12 for raising and lowering the lifting plate. One end of each of the two electric telescopic rods 12 is fixedly connected to the lifting plate 13 for separating the pressure roller 8 and the laminating roller 11. The rear side of the base plate 1 is equipped with a conveying assembly for conveying the printed material to the laminating and pasting working position. The adjacent side of the left and right end groove blocks 9 is equipped with an adhesive application assembly for applying adhesive to the surface of the printed material to provide the necessary bonding conditions for laminating and pasting. The front side of the base plate 1 is equipped with a limiting mechanism 2 for fixing and limiting the printed material.

[0033] Specifically, when the printed material passes between the pressure roller 8 and the laminating roller 11, the laminating roller 11 moves up and down via the movable U-shaped bracket 10 according to the thickness of the printed material, achieving full adhesion between the film and the printed material. The rotation of motor 5 drives gears 6 and 7, and the pressure roller 8 to rotate synchronously, thus achieving lamination and transport of the printed material. Because the surface of the printed material is coated with adhesive, and the laminating roller 11 exerts downward pressure on the printed material, excess adhesive on the surface of the printed material overflows from the edges and remains on the pressure roller 8. Prolonged residue can affect the normal operation of the machine. The pressure roller 8 needs to be disassembled and cleaned regularly. During disassembly, firstly, the electric telescopic rod on the movable U-shaped bracket 10 is activated to move the lifting plate upward, so that the coating roller 11 is separated from the pressure roller 8 to prevent them from sticking together due to glue. Then, the movable U-shaped bracket 10 is pushed backward along the track of the groove block 9, so that the coating roller 11 is removed from above the pressure roller 8. Finally, the fixing block 4 on the load-bearing bracket 3 is rotated to remove the coating roller 11 and the gear 7 fixedly connected to it from above for cleaning. This process reduces the disassembly of parts and facilitates the disassembly and cleaning of the pressure roller 8.

[0034] Reference Figure 6The limiting mechanism 2 includes a base plate 201, which provides an installation platform for subsequent components. The rear side of the base plate 201 is fixedly connected to the front side of the base plate 1. Sliding grooves 202 are provided on the top left and right sides of the base plate 201, providing a track for the sliding of the movable bracket 203. The movable bracket 203 is slidably connected to the inner wall of each of the two sliding grooves 202, realizing the positional movement on the base plate 201 and providing an installation bracket for subsequent components. The top adjacent sides of the two movable brackets 203 are fixedly connected to a groove plate 204, providing sliding space for the long rack slider 205. The bottom of the groove plate 204 is slidably connected to the long rack slider 205. The bottom of the long rack slider 205 is meshed with a gear 3 206. The bottom of the gear 3 206 is meshed with a long rack slider 208. The long rack slider 205, gear 3 206 and long rack slider 208 form a connection. The movement is used to realize the displacement of the U-shaped plate 211. The bottom of the long rack slider 208 is slidably connected to the groove plate 209, which provides sliding space for the long rack slider 208. The left and right ends of the groove plate 209 are respectively fixedly connected to the adjacent side of the corresponding moving bracket 203 to ensure the stability of the groove plate 209. The front sides of the groove plate 1 204 and the groove plate 209 are both fixedly connected to the motor 3 207, which provides power for the rotation of the gear 3 206. The output end of the motor 3 207 is fixedly connected to the front side of the gear 3 206, which directly transmits the rotational power of the motor 3 207 to the gear 3 206, ensuring the efficiency and stability of power transmission. The rear sides of the groove plate 1 204 and the groove plate 209 are both fixedly connected to the support rod 210 to provide support for the U-shaped plate 211. The rear ends of the two support rods 210 are both fixedly connected to the U-shaped plate 211 to fix and limit the printed material.

[0035] Specifically, before laminating the printed object, the motor 207 is started to drive the gear 206 to rotate, causing the long rack slider 205 and the long rack slider 208 to slide in opposite directions on the groove plate 204 and the groove plate 209, respectively. This allows the support rod 210, which is fixedly connected to it, and the U-shaped plate 211, which is fixedly connected to the support rod 210 and placed on the outer wall of the pressure roller 8, to slide, thereby fixing and limiting the printed objects of different widths. When the pressure roller 8 is disassembled, the limiting device can be removed by simply sliding forward along the sliding groove 202 on the bottom plate 201, which is fixedly connected to the front side of the bottom plate 1. In addition, the edge of the U-shaped plate 211 is sharp, which can cut the film on the laminating roller 11 according to the width of the printed object, thus solving the problem of mismatch between the width of the film and the printed object.

[0036] Reference Figure 3 , Figure 4 and Figure 5The adhesive application assembly includes a base plate 3 14, which provides an installation platform for the fixed U-shaped brackets 15. The front side of the base plate 3 14 is fixedly connected to the rear side of the base plate 1. The top left and right sides of the base plate 3 14 are fixedly connected to the fixed U-shaped brackets 15, providing a base for the installation and sliding of the adhesive rod 16. The adhesive rod 16 is slidably connected to the inner wall of the fixed U-shaped brackets 15 to release the adhesive. The left and right ends of the outer wall of the adhesive rod 16 are respectively engaged with the inner walls of the two fixed U-shaped brackets 15. The left end of the adhesive rod 16 is connected to a bend tube 17 for dispensing adhesive. The transmission provides a stable and safe channel. The other end of the bend 17 is connected to the glue extraction tube 18 for extracting and conveying glue. The bottom end of the glue extraction tube 18 is connected to the glue tank 19 for storing glue and supplying glue to the device. The bottom of the glue tank 19 is fixedly connected to the top of the base plate 14 to ensure the safety of glue storage. The transmission assembly includes the base plate 20, which provides an installation base for the fixed bracket 21. The front side of the base plate 20 is fixedly connected to the rear side of the base plate 14. The top left and right sides of the base plate 1 and the base plate 20 are connected to each other. Fixed brackets 21 are fixedly connected to both sides to provide support structure for the rolling shaft 23 and the conveyor belt 24. Motor 22 is fixedly connected to the left side of the left fixed bracket 21 at the rear to provide power source for the conveying assembly. The output end of motor 22 passes through the left fixed bracket 21 at the rear and is fixedly connected to the rolling shaft 23 to realize the cyclic rotation of the conveyor belt 24. The conveyor belt 24 is set on the outside of the two rolling shafts 23 to ensure the safety and stability of the object during the conveying process. The outer wall of the glue rod 16 is provided with a sponge tube 25, which can fully absorb the glue on the glue rod 16 and spread the glue evenly when in contact with the object. The left and right ends of the sponge tube 25 are slidably connected to fixed C-shaped plates 26 to fix the sponge tube 25 and prevent it from falling off. The front and rear sides of the outer walls of the two fixed U-shaped brackets 15 are fixedly connected to electric telescopic rods 27 to provide power for the movement of the lifting plate. One end of the two electric telescopic rods 27 is fixedly connected to a lifting plate 28, which can adjust the position of the glue rod 16 to ensure that the glue can be evenly applied to the surface of the printed object.

[0037] Specifically, the base plate 14 provides an installation platform for the fixed U-shaped bracket 15, which in turn provides a foundation for the installation and sliding of the glue rod 16. The glue rod 16 releases the glue. The flexible tube 17 ensures the glue rod 16 moves smoothly up and down on the fixed U-shaped bracket 15, providing a stable and safe channel for glue transfer. The glue extraction tube 18 extracts and transports the glue. The glue tank 19 stores the glue and supplies it to the device. The bottom of the glue tank 19 is fixedly connected to the top of the base plate 14, ensuring stability during equipment operation and guaranteeing the safety of glue storage. The base plate 20 provides an installation foundation for the fixed bracket 21. The frame 21 provides a support structure for the rolling shaft 23 and the conveyor belt 24. The motor 22 provides a power source for the conveying components. The rolling shaft 23 enables the conveyor belt 24 to rotate cyclically. The conveyor belt 24 can adapt to objects of different weights and shapes, ensuring the safety and stability of the objects during the conveying process. The sponge tube 25 can fully absorb the glue on the glue rod 16 and evenly apply the glue when in contact with the object. The fixed C-shaped plate 26 makes it easy to remove the sponge tube 25 from the glue rod 16 for cleaning and replacement, ensuring the consistency and stability of the glue application effect. The electric telescopic rod 27 provides power for the movement of the lifting plate. The lifting plate can adjust the position of the glue rod 16 to ensure that the glue can be evenly applied to the surface of the printed object.

[0038] Reference Figure 1 , Figure 3 and Figure 4 The inner wall of the conveyor belt 24 is provided with a support plate 30, which provides a stable support structure for the conveyor belt 24. The bottom left and right sides of the support plate 30 are fixedly connected with support frames 29, which improves the stability of the support. The bottom of the two support frames 29 is fixedly connected to the top of the base plate 14, which distributes the load during the operation of the equipment. The rear sides of the two load-bearing brackets 3 are fixedly connected with snap fasteners 33. The rear side of the load-bearing brackets 3 is engaged with the rear side of the fixing block 4 through snap fasteners 33, which ensures the firmness of the connection between the fixing block 4 and the load-bearing brackets 3. The left side of the glue bucket 19 is threadedly connected with a filling plug 34 to prevent glue from leaking out during storage and transportation. The bottom of the pressure roller 8 is provided with a glue filling box 31 to prevent glue from contaminating the base plate 1. The bottom middle of the glue filling box 31 is fixedly connected to the top middle of the base plate 1. The front side of the glue filling box 31 is threadedly connected with an outlet plug 32 to control the outflow of stored glue.

[0039] Specifically, the support plate 30 provides a stable support structure for the conveyor belt 24, which enhances the load-bearing capacity of the conveyor belt 24, prevents it from deforming or collapsing due to the weight of the material, and ensures the smooth operation of the conveyor belt 24. The support frame 29 improves the stability of the support. The bottom of both support frames 29 are fixedly connected to the top of the base plate 3 14, transferring the weight of the support plate 30 and the conveyor belt 24 and the pressure generated during operation to the base plate 3 14, dispersing the load during equipment operation and ensuring the reliability and safety of the entire equipment structure. The snap-fit ​​buckle 33 ensures the firmness of the connection between the fixing block 4 and the load-bearing bracket 3, allowing it to withstand a certain amount of external force without easily separating. The filling plug 34 prevents glue from leaking out during storage. The glue filling box 31 collects the glue dripping from the pressure roller 8, preventing it from contaminating the base plate 1. The outlet plug 32 controls the outflow of stored glue.

[0040] Working Principle: Since the printed material is coated with adhesive, as it passes between the pressure roller 8 and the laminating roller 11, the laminating roller 11 moves up and down via the movable U-shaped support 10 according to the thickness of the printed material, achieving full adhesion between the film and the printed material. The rotation of motor 5 drives gears 6 and 7, and the pressure roller 8 to rotate synchronously, thus achieving lamination and transport of the printed material. Simultaneously, the laminating roller 11 exerts downward pressure on the printed material, causing excess adhesive to overflow from the edges and remain on the pressure roller 8. Prolonged residue can affect the normal operation of the machine, therefore... The pressure roller 8 should be disassembled and cleaned regularly. During disassembly, first activate the electric telescopic rod on the movable U-shaped bracket 10 to move the lifting plate upward, so that the coating roller 11 is separated from the pressure roller 8 to prevent them from sticking together due to glue. Then, push the movable U-shaped bracket 10 backward along the track of the groove block 9 so that the coating roller 11 is removed from above the pressure roller 8. Finally, rotate the fixing block 4 on the load-bearing bracket 3 to remove the coating roller 11 and the gear 2 7 fixedly connected to it from above for cleaning. This process reduces the disassembly of parts and facilitates the disassembly and cleaning of the pressure roller 8.

[0041] Furthermore, through the fixed connection between the support rod 210 and the U-shaped plate 211, after confirming the width of the printed material, the motor 3 207 is started to drive the gear 3 206 to rotate, so that the long rack slider 1 205 and the long rack slider 208 slide in opposite directions on the groove plate 1 204 and the groove plate 209 respectively. This allows the support rod 210 fixedly connected to it and the U-shaped plate 211 fixedly connected to the support rod 210 and placed on the outer wall of the pressure roller 8 to slide left and right, thereby fixing and limiting printed materials of different widths. When the pressure roller 8 is disassembled, the limiting device can be removed by simply sliding forward along the sliding groove 202 on the bottom plate 2 201 fixedly connected to the front side of the bottom plate 1. In addition, the edge of the U-shaped plate 211 is sharp, which can cut the film on the laminating roller 11 according to the width of the printed material, thus solving the problem of mismatch between the width of the film and the printed material.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
