Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-5 , an adhesive - applying device for a fabric laminating machine, including a fixed frame 1, a bracket 2, a glue - rolling cylinder 3, a lifting component and a glue - applying component. On the upper end surface of the fixed frame 1, brackets 2 are symmetrically fixed on the left and right. A glue - rolling cylinder 3 is rotatably arranged between the two side brackets 2. On the upper end surface of the fixed frame 1 and below the glue - rolling cylinder 3, a lifting component is arranged. The lifting component includes a fixed seat 4 and a lifting seat 5. A sliding groove is arranged on the upper end surface of the fixed seat 4, and the lifting seat 5 is slidably arranged in the sliding groove. A glue - applying component is fixedly arranged on the top of the lifting seat 5. A driving component is arranged in the lifting component, and the driving component drives the lifting component to adjust the height of the glue - applying component. When the distance between the glue - applying component and the glue - rolling cylinder 3 becomes larger, a thicker layer of glue can be coated on the glue - rolling cylinder 3. By swinging the scraper 8 towards one side of the glue - rolling cylinder 3, the glue coated on the glue - rolling cylinder 3 can be scraped more evenly, and the thickness of the glue can be further adjusted.

[0025] Please refer to Figure 3, The above-mentioned glue - applying assembly can be any one. An embodiment provided by the present application is that the glue - applying assembly includes a glue - applying base 6. The upper end face of the glue - applying base 6 is an arc surface and is adapted to the glue - rolling cylinder 3. A glue groove is arranged on the upper end face of the glue - applying base 6. A glue - feeding port 19 is arranged on the left - hand end face of the glue - applying base 6 and is communicated with the glue groove. On the front and rear of the right - hand end face of the glue - applying base 6, side frames 7 are fixedly arranged. A scraping plate 8 is rotatably arranged between the two side frames 7. Glue is injected into the glue groove through the glue - feeding port 19. The glue overflows in the glue groove and adheres to the glue - rolling cylinder 3. The scraping plate 8 can swing between the two side frames 7. By controlling the distance between the scraping plate 8 and the glue - rolling cylinder 3, a certain thickness of the glue adhered to the glue - rolling cylinder 3 can be scraped off, so as to adjust the thickness of the glue on the glue - rolling cylinder 3. It should be noted that the glue - rolling cylinder 3 rotates counter - clockwise and can be driven by a synchronous belt on the fabric laminating machine, so that the moving speed of the glue - rolling cylinder 3 is consistent with the moving speed of the fabric. The fabric laminating machine is well - known to those skilled in the art, so it will not be described in detail.

[0026] Please refer to Figures 2-3 , The above - mentioned driving assembly can be any one. An embodiment provided by the present application is that the driving assembly includes a driving motor 15, a worm 13, a screw rod 14, a connecting rod 17 and a worm wheel 18. Worm wheels 18 are rotatably arranged on both sides of the inner wall of the bottom of the sliding groove. A screw rod 14 is fixedly arranged on the top of the worm wheel 18. Worms 13 are rotatably arranged on the left - and right - hand inner walls of the sliding groove. A connecting rod 17 is connected between the two worms 13. The worm 13 meshes with the corresponding worm wheel 18. On one side outer wall of the fixed seat 4, a driving motor 15 is fixedly arranged. The output end of the driving motor 15 is connected to one of the worms 13. Threaded holes are arranged on both sides of the bottom end face of the lifting seat 5. The screw rod 14 is in threaded connection with the threaded holes. The driving motor 15 drives the worm 13 and the connecting rod 17 to rotate. Further, it can drive the two worm wheels 18 to rotate synchronously. Further still, it drives the two screw rods 14 to rotate synchronously, so as to control the stable lifting of the lifting seat 5 in the sliding groove. By driving the stable movement of the lifting assembly through the driving assembly, the glue - applying assembly can have a good glue - applying efficiency for the glue - rolling cylinder 3.

[0027] Please refer to Figures 2-3 , When the above - mentioned worm 13 and connecting rod 17 rotate, there is a problem of instability. To solve the above problem, a support block 16 is fixedly arranged on the inner wall of the bottom of the sliding groove. A through - hole is arranged on the support block 16. The connecting rod 17 passes through the through - hole and is rotatably connected to the through - hole. By adding the support block 16, the stability of the rotation of the worm 13 and the connecting rod 17 can be increased.

[0028] Please refer to Figures 2-3 , When the above - mentioned lifting seat 5 moves downward in the sliding groove, it is easy to contact the worm wheel 18, causing wear of the worm wheel 18. To avoid the above situation, the height of the support block 16 is greater than the height of the worm wheel 18. When the lifting seat 5 descends in the sliding groove and contacts the support block 16, the lowest height of the lifting seat 5 will be reached.

[0029] Please refer to Figure 1 and 4 As described above, the squeegee 8 needs to be easy to operate during use. To meet the above requirements, a U-shaped frame 10 is fixedly arranged on the outer wall of one side of the glue applicator base 6. A cylinder 11 is rotatably arranged on the U-shaped frame 10. The output end of the cylinder 11 is fixedly provided with a bushing 12. A cross bar 9 is fixedly arranged on the end face of the squeegee 8 corresponding to the cylinder 11. The cross bar 9 is rotatably connected to the bushing 12. The cylinder 11 can swing on the U-shaped frame 10. The cylinder 11 controls the movement of the bushing 12. Through the cooperation of the cross bar 9, the squeegee 8 can swing between the two side frames 7, so as to adjust the distance between the squeegee 8 and the glue roller 3, and achieve the purpose of adjusting the thickness of the glue on the glue roller 3.
