Description

Technical Field

[0001] This utility model relates to the field of synthetic leather processing technology, specifically to an adhesive device for polyurethane synthetic leather. Background Technology

[0002] Chinese patent document CN222769001U discloses an adhesive device for polyurethane synthetic leather, specifically relating to the field of adhesive devices. The device includes a workbench connected to multiple pillars, which collectively support a top plate. A lifting mechanism is mounted on the top plate, with a connecting frame connected to the bottom of the lifting mechanism. An mounting frame is mounted at the bottom of the connecting frame, and an adhesive mechanism is mounted at the bottom of the mounting frame. This invention, through the lifting mechanism, allows for adjustment of the height of the two bottom flattening pillars, facilitating the pressing and bonding of synthetic leather of different thicknesses on the workbench. Simultaneously, it allows for adjustment of the pressing force. Furthermore, the method of pushing from the center outwards by the two flattening pillars balances the force on both ends of the leather, ensuring that the synthetic leather and the bottom sponge pad remain stationary, preventing misalignment during bonding, and thus improving the bonding quality. This, in turn, improves the quality of the manufactured soccer products.

[0021] Furthermore, a hydraulic cylinder 10 is installed on the side surface of the movable mold frame 4. The output end of the hydraulic cylinder 10 is connected to the lifting platform 2 through the hydraulic support rod 9. By opening the hydraulic cylinder 10, the hydraulic support rod 9 can be used to drive and control the installation height of the lifting platform 2, thereby facilitating the control and adjustment of the installation height of the glue coating roller 3 and the pressing roller 5 on the lifting platform 2.

[0022] Furthermore, a drive motor 7 is installed on the movable mold frame 4. The output end of the drive motor 7 is connected to a first gear 6 via a rotating shaft. The center of the surface of the first gear 6 is connected to the pressing roller 5 via a rotating shaft. The first gear 6 is connected to a second gear 12 via meshing transmission. The center of the surface of the second gear 12 is connected to the glue coating roller 3 via a transmission shaft 8. By turning on the drive motor 7, the first gear 6 is driven to mesh with the second gear 12, thereby driving and controlling the pressing roller 5 and the glue coating roller 3 to rotate synchronously.

[0023] Furthermore, a servo motor 15 is installed on one side of the machining fixed table 1. The output end of the servo motor 15 is connected to the lead screw 14 through a rotating shaft. The lead screw slider 13 drives the moving mold frame 4 to slide horizontally along the surface of the lead screw 14. By turning on the servo motor 15, the lead screw slider 13 is driven and controlled to slide horizontally along the surface of the lead screw 14, thereby driving and controlling the moving mold frame 4 to make horizontal linear movement along the direction of the machining fixed table 1.

[0024] Furthermore, the bottom of the mobile mold frame 4 is equipped with mobile wheels 11, which facilitates flexible movement of the mobile mold frame 4 and improves its mobility.

[0025] Working principle: In use, the polyurethane synthetic leather to be processed is laid flat on the surface of the processing fixed table 1. Then, the servo motor 15 is turned on to drive the lead screw slider 13 to slide horizontally along the surface of the lead screw 14, thereby driving the moving mold frame 4 to move horizontally linearly along the processing fixed table 1. Then, the drive motor 7 is turned on to drive the first gear 6 to drive the second gear 12 to mesh and transmit power, thereby driving the pressing roller 5 and the coating roller 3 to rotate synchronously. Under the control of the drive motor 7, the coating roller 3 can be driven to apply the polyurethane... The synthetic leather surface is coated with adhesive. After the adhesive coating is completed, another synthetic leather material is laid on the coated synthetic leather surface and quickly pressed and bonded by the pressing roller 5. The hydraulic cylinder 10 can be activated to drive and control the hydraulic support rod 9 to adjust the installation height of the lifting platform 2. This facilitates the control and adjustment of the installation height of the adhesive coating roller 3 and the pressing roller 5 on the lifting platform 2, making it easier for the adhesive coating roller 3 and the pressing roller 5 to bond to the synthetic leather surface, and also facilitating the further installation and disassembly of the adhesive coating roller 3 and the pressing roller 5.
