[0041] Specifically, a pressing component 2 is symmetrically arranged in the frame 1, and the pressing component 2 clamps the pressing fabric 23 and the fiber fabric 6 for clamping and pressing. A coating component 3 is attached to one end of the pressing fabric 23, and the coating component 3 rotates with the attached pressing component 2. A feeding component 4 is transmission-connected to the top of the coating component 3, and the feeding component 4 intermittently feeds the adhesive to the surface of the coating roller 31. A guide component 5 transmission-connected at one end of the coating component 3 performs a pretreatment step of evenly scraping the adhesive on the surface of the coating roller 31, thereby reducing the phenomenon that the adhesive is retained between the coating roller 31 and the pressing fabric 23 due to the feeding between the coating roller 31 and the pressing fabric 23, and the guide component 5 is transmission-connected to the coating component 3, so that the coating guides and self-cleans the adhesive retained during the scraping process, thereby preventing the adhesive from adhering to the scraper 51 and affecting the use effect of the guide plate.

[0043] Specifically, the laminating roller 21 in the laminating component 2 is a right-angled triangle structure. The guide belts 22 sleeved at both ends of the laminating roller 21 are used to adhere the laminating fabric 23, so that the laminating fabric 23 can be pressed under the action of the guide belts 22.

[0045] Specifically, the gear plates 32 symmetrically fixedly connected at both ends of the coating roller 31 are fitted with the pressing roller 21, so that when the pressing roller 21 drives the fabric to move, the outlet wheel plate fitted with the pressing roller 21 is synchronously driven to rotate, and the eccentric shaft 34 fixedly connected to the transmission gear 33 meshing at the top of the gear plate 32 drives the feeding assembly 4 through the connecting arm 35, so that the feeding assembly 4 intermittently feeds the adhesive to the surface of the coating roller 31, thereby reducing the phenomenon of adhesive being retained between the coating roller 31 and the pressing fabric 23;

[0047] Specifically, the feeding chamber 41 in the feeding assembly 4 is a rectangular frame structure, and the control plate 44 movably connected at the bottom of the feeding chamber 41 controls the discharge amount. The fixed ear 46 fixedly connected at one end of the control plate 44 is used to fix the support spring 47. The support spring 47 elastically supports the control plate 44 to perform a reset movement. The connecting rod 48 fixedly connected at one end of the fixed ear 46 is transmission-connected to the connecting arm 35. When the transmission gear 33 rotates, the connecting arm 35 drives the control plate 44 connected to the connecting rod 48 to reciprocate, so that the control plate 44 intermittently closes the feeding chamber 41, so that the adhesive at the discharge end of the feeding chamber 41 is intermittently fed to the surface of the coating roller 31, thereby reducing the phenomenon of adhesive retention caused by continuous feeding; the spiral shaft 42 rotatably connected in the feeding chamber 41 is meshed with the transmission gear 33 through the driven gear 43 fixedly connected at both ends, so that the spiral shaft 42 guides the stirring of the adhesive in the feeding chamber 41, thereby improving the feeding of the feeding chamber 41 to be more uniform and improving the feeding efficiency of the device;

[0048] The material guide assembly 5 includes a scraper 51, and the scraper 51 is fixed on the frame 1. A stirring rod 52 is arranged inside the scraper 51.

One end of the linkage arm 57 away from the positioning column 56 is fixedly connected to a shifting block; the support rod 5 The two ends of the convex gear 554 are symmetrically fixedly connected, the top of the convex gear 554 is fixedly connected to the top of the convex gear 554, the top of the convex gear 554 is rotatably connected to the transmission wheel 555, the transmission wheel 555 is sleeved with a transmission chain 556, one end of the transmission chain 556 is fixedly connected to a linkage column 557, and the linkage column 557 is in contact with the shifting block; one end of the convex gear 554 is meshed with a gear block 553, and the gear block 553 is sleeved on the support rod 55, and one end of the gear block 553 is meshed with a transmission gear 33;

[0049] Specifically, when the transmission gear 33 rotates through the gear plate 32, the gear block 553 engaged with the transmission gear 33 drives the convex gear 554 to rotate synchronously, and the transmission wheel 555 fixedly connected to the top of the convex gear 554 drives the transmission chain 556 to move, so that the linkage column 557 fixedly connected to the transmission chain 556 drives the shift block fixed on the linkage arm 57 to move, so that the ring 54 fixedly connected to the linkage arm 57 moves in a directional manner along the support rod 55, so that the stirring rod fixedly connected to the ring 54 and the cleaning plate 53 can reciprocate between the scraper 51 and the coating roller 31, so that the stirring rod 52 stirs the adhesive retained between the scraper 51 and the coating roller 31 to reduce the hardening of the adhesive. At the same time, the cleaning plate 53 cleans the inner wall of the scraper 51 to prevent the adhesive from sticking to the inner wall of the scraper 51, causing the hardened adhesive to affect the flatness of the fabric pressing.

[0050] Working principle: a pressing assembly 2 is symmetrically arranged in the frame 1, and the pressing assembly 2 clamps the pressing fabric 23 and the fiber fabric 6 for clamping and pressing. A coating assembly 3 is attached to one end of the pressing fabric 23, and the coating assembly 3 rotates with the attached pressing assembly 2. A feeding assembly 4 is connected to the top of the coating assembly 3 in a transmission manner, and the feeding assembly 4 intermittently feeds the adhesive to the surface of the coating roller 31. A material guide assembly 5 connected in a transmission manner at one end of the coating assembly 3 performs a pretreatment step of evenly scraping the adhesive on the surface of the coating roller 31, thereby reducing the phenomenon that the adhesive is retained between the coating roller 31 and the pressing fabric 23 due to the loading of the material between the coating roller 31 and the pressing fabric 23. When the transmission gear 33 rotates through the gear plate 32, the gear block 553 engaged with the transmission gear 33 drives the convex gear 554 to rotate synchronously. The transmission wheel 555 fixedly connected to the top of the convex gear 554 drives the transmission chain 556 to move, so that the linkage column 557 fixedly connected to the transmission chain 556 drives the shifting block fixed on the linkage arm 57 to move, so that the collar 54 fixedly connected to the linkage arm 57 moves in a directional manner along the support rod 55, so that the stirring rod and the cleaning plate 53 fixedly connected to the collar 54 can reciprocate between the scraper 51 and the coating roller 31, so that the stirring rod 52 stirs the adhesive retained between the scraper 51 and the coating roller 31 to reduce the hardening of the adhesive. At the same time, the cleaning plate 53 cleans the inner wall of the scraper 51 to prevent the adhesive from sticking to the inner wall of the scraper 51, so that the coating can guide and self-clean the adhesive retained in the scraping process to prevent the adhesive from sticking in the scraper 51 and affecting the use effect of the guide plate.
