[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0040] Refer to Figure 1-10, A pressing device based on a highly elastic fiber composite fabric, comprising a frame 1 and a pressing assembly 2; the pressing assembly 2 is symmetrically arranged inside the frame 1, and the pressing assembly 2 clamps and presses the fiber fabric 6 through two pressing fabrics 23. One end of the pressing assembly 2 is fitted and drivingly connected to a coating assembly 3; the coating assembly 3 is drivingly connected to a feeding assembly 4 through the pressing assembly 2. The feeding assembly 4 intermittently supplies materials to the surface of the coating roller 31 in the coating assembly 3. One end of the coating assembly 3 is provided with a guiding assembly 5. The adhesive on the surface of the coating roller 31 is pretreated by the scraper 51 inside the guiding assembly 5, and the guiding assembly 5 is self-cleaned through the driving connection of the coating assembly 3;

[0041] Specifically, the pressing assembly 2 is symmetrically arranged in the frame 1. The pressing assembly 2 clamps and presses the fiber fabric 6 with the pressing fabric 23. One end of the pressing fabric 23 is fitted with a coating assembly 3. The coating assembly 3 and the fitted pressing assembly 2 perform rotational motion. At the top of the coating assembly 3, a feeding assembly 4 is drivingly connected. The feeding assembly 4 intermittently supplies the adhesive to the surface of the coating roller 31. The guiding assembly 5 drivingly connected to one end of the coating assembly 3 performs a pretreatment step of evenly scraping the adhesive on the surface of the coating roller 31, reducing the phenomenon that the adhesive stays between the coating roller 31 and the pressing fabric 23 due to feeding. Through the driving connection between the guiding assembly 5 and the coating assembly 3, the adhesive staying during the scraping process is diverted and self-cleaned, avoiding the adhesion of the adhesive in the scraper 51 and affecting the use effect of the guiding plate;

[0042] The pressing assembly 2 includes a pressing roller 21, and the pressing roller 21 is rotatably arranged on the frame 1. Guide belts 22 are symmetrically arranged at both ends of the pressing roller 21. A separating assembly 24 is arranged at one end of the pressing roller 21, and the separating assembly 24 is fixed on the frame 1; the separating assembly 24 includes a guide plate 241. Fixed connection plates 242 are fixedly connected to both ends of the guide plate 241, and the fixed connection plates 242 are fixed on the frame 1. A connecting column 243 is fixedly connected to one end of the guide plate 241. A rotating shaft rod 244 is rotatably arranged inside the connecting column 243, and a rotating roller 245 is fixedly connected to the outside of the rotating shaft rod 244;

[0043] Specifically, the pressing roller 21 in the pressing assembly 2 has a right-angled triangular structure. The guide belts 22 sleeved at both ends of the pressing roller 21 are used to adhere the pressing fabric 23, so that the pressing fabric 23 can perform fabric pressing under the action of the guide belts 22. The separating assembly 24 arranged at one end of the pressing assembly 2 separates the pressing fabric 23 adhered by the guide belts 22 from the pressing roller 21. The guide plate 241 in the separating assembly 24 separates the fabric pressed outside the pressing roller 21. The separated fabric moves along the guide plate 241 to the rotating roller 245, making the fabric guiding of this device more convenient and reducing the tediousness of the manual preparation steps of the pressing fabric 23;

[0044] The coating assembly 3 includes a coating roller 31. Symmetrically fixed to both ends of the coating roller 31 are gear discs 32. Meshing with the top of the gear discs 32 is a transmission gear 33. Fixed to one end of the transmission gear 33 is an eccentric shaft 34. Sleeved on one end of the eccentric shaft 34 is a connecting arm 35, and the connecting arm 35 is rotatably connected to the feeding assembly 4.

[0045] Specifically, the gear discs 32 symmetrically and fixedly connected to both ends of the coating roller 31 are in contact with the pressing roller 21. When the pressing roller 21 drives the fabric to move, it synchronously drives the rotating wheel disc in contact with the pressing roller 21 to rotate. The eccentric shaft 34 fixedly connected to the transmission gear 33 meshing with the top of the gear disc 32 drives the feeding assembly 4 through the connecting arm 35, so that the feeding assembly 4 intermittently supplies the adhesive to the surface of the coating roller 31, reducing the phenomenon of the adhesive remaining between the coating roller 31 and the pressed fabric 23.

[0046] The feeding assembly 4 includes a feeding chamber 41. At the bottom end of the feeding chamber 41 is movably provided a control board 44. Fixed to one end of the control board 44 is a fixed ear 46. Fixed to one end of the fixed ear 46 is a connecting rod 48, and the connecting rod 48 is movably connected to the connecting arm 35. Fixed to the top of the fixed ear 46 is a support spring 47, and the support spring 47 is fixed on the feeding chamber 41. Rotatably connected inside the feeding chamber 41 is a spiral shaft 42. Both ends of the spiral shaft 42 penetrate the feeding chamber 41 and are fixedly connected with driven gears 43, and the driven gears 43 mesh with the transmission gear 33. Rotatably provided at the bottom end of the feeding chamber 41 is a support column 45, and the support column 45 limits the position of the control board 44.

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

[0048] The material guiding assembly 5 includes a scraping plate 51, and the scraping plate 51 is fixed on the frame 1. A stirring rod 52 is arranged inside the scraping plate 51. One end of the stirring rod 52 is fixedly connected with a cleaning plate 53, and the cleaning plate 53 is attached to the inner wall of the scraping plate 51. The top end of the stirring plate is fixedly connected with a collar 54. A support rod 55 is sleeved inside the collar 54, and the support rod 55 is fixed on the frame 1; The top end of the collar 54 is fixedly connected with a positioning column 56. Linkage arms 57 are symmetrically and fixedly connected to both ends of the positioning column 56. The end of the linkage arm 57 away from the positioning column 56 is fixedly connected with a shifting block; Fixed rings 551 are symmetrically and fixedly connected to both ends of the support rod 55. A rotating shaft seat 552 is fixedly connected to the top end of the fixed ring 551. A convex gear 554 is rotatably connected to the top end of the rotating shaft seat 552. A transmission wheel 555 is fixedly connected to the top end of the convex gear 554. A transmission chain 556 is sleeved on the transmission wheel 555. One end of the transmission chain 556 is fixedly connected with a linkage column 557, and the linkage column 557 is attached to the shifting block; One end of the convex gear 554 meshes with a gear block 553, and the gear block 553 is sleeved on the support rod 55. One end of the gear block 553 meshes with a transmission gear 33;

[0049] Specifically, when the transmission gear 33 rotates through the gear disc 32, the gear block 553 meshed with the transmission gear 33 drives the convex gear 554 to rotate synchronously. The transmission wheel 555 fixedly connected to the top end 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 directionally along the support rod 55, realizing the reciprocating movement of the stirring rod and the cleaning plate 53 fixedly connected to the collar 54 between the scraping plate 51 and the coating roller 31. The stirring rod 52 stirs the adhesive retained between the scraping plate 51 and the coating roller 31, reducing the hardening phenomenon of the adhesive. At the same time, the cleaning plate 53 cleans the inner wall of the scraping plate 51, avoiding the adhesion of the adhesive on the inner wall of the scraping plate 51, resulting in the hardened adhesive affecting the flatness of the fabric pressing.

[0050] Working principle: In the frame 1, the pressing components 2 are symmetrically arranged. The pressing components 2 clamp and press the fiber fabric 6 with the pressed fabric 23. At one end of the pressed fabric 23, a coating component 3 is attached. The coating component 3 and the attached pressing component 2 perform a rotational motion. At the top of the coating component 3, a feeding component 4 is drivingly connected. The feeding component 4 intermittently supplies the adhesive to the surface of the coating roller 31. The guiding component 5 drivingly connected at one end of the coating component 3 preprocesses the adhesive on the surface of the coating roller 31 by evenly scraping it, reducing the phenomenon that the adhesive stays between the coating roller 31 and the pressed fabric 23 due to feeding. When the transmission gear 33 rotates through the gear disc 32, the gear block 553 engaged with the transmission gear 33 drives the cam gear 554 to rotate synchronously. The transmission wheel 555 fixedly connected to the top of the cam gear 554 drives the transmission chain 556 to move, so that the linkage column 557 fixedly connected to the transmission chain 556 drives the block fixed on the linkage arm 57 to move, causing the collar 54 fixedly connected to the linkage arm 57 to move directionally along the support rod 55, realizing the reciprocating movement of the stirring rod and the cleaning plate 53 fixedly connected to the collar 54 between the scraper 51 and the coating roller 31. The stirring rod 52 stirs the adhesive staying between the scraper 51 and the coating roller 31, reducing the hardening phenomenon of the adhesive. At the same time, the cleaning plate 53 cleans the inner wall of the scraper 51, preventing the adhesive from sticking to the inner wall of the scraper 51, enabling the coating to divert and self-clean the adhesive staying during the scraping process, and avoiding the adhesion of the adhesive in the scraper 51, which affects the use effect of the guiding plate.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and its concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
