[0024] 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 the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

[0025] The following gives specific embodiments.

[0026] Please refer to Figure 1 - Figure 5 , the present invention provides an environmentally friendly packaging bag composite glue-brushing device, including a body 1. Guide rollers 3 are rotatably connected to the inner walls at both ends of the body 1. A composite tape 4 is rotatably connected to the outside of multiple guide rollers 3. Open slots 8 are provided at both ends of the body 1. Slide blocks 9 are sleeved on the inner walls of each open slot 8. Transmission rods 10 are rotatably connected to the top inner walls of each slide block 9. Insert blocks 11 are fixedly connected to one ends of each transmission rod 10. A glue-brushing roller 5 is arranged between the two insert blocks 11. Insert slots 12 are provided in the inner walls at both ends of the glue-brushing roller 5. The outer walls of the insert blocks 11 are snap-fitted with the inner walls of each insert slot 12. Both sides of the glue-brushing roller 5 are in contact with one side of the transmission rod 10 through the insert blocks 11. The outer wall of the glue-brushing roller 5 is rotatably connected to one side of the composite tape 4 through the two transmission rods 10. First push rods 13 are fixedly connected to one sides at the bottoms of each slide block 9. The outer walls of the other ends of each first push rod 13 are fixedly connected to the inner wall of the body 1. A glue box 19 is sleeved at the bottom of the glue-brushing roller 5. One side of the glue box 19 is fixedly connected to the body 1. Two diversion pipes 20 are fixedly connected to one end of the glue box 19. A rectangular groove 21 is provided in the inner wall at one end of the glue box 19. Multiple third push rods 22 are fixedly connected to the inner wall of the rectangular groove 21. A glue scraping plate 23 is fixedly connected to one ends of the multiple third push rods 22. The outer wall of the glue scraping plate 23 slides on the inner wall of the rectangular groove 21 through the multiple third push rods 22, and the other side of the glue scraping plate 23 is in contact with one side of the glue-brushing roller 5 through the multiple third push rods 22.

[0027] During operation, the composite tape 4 is passed through a plurality of guide rollers 3. When it is necessary to apply glue to the composite tape 4, the plurality of guide rollers 3 are used to complete the guiding work of the composite tape 4, so that the composite tape 4 moves inside the machine body 1. Then, by connecting the diversion tube 20 with the glue supply system, the glue can circulate inside the glue box 19. Then, the transmission rod 10 is driven to rotate. By connecting the insertion block 11 with the inner wall of the slot 12, the glue brushing roller 5 can rotate synchronously with the transmission rod 10. The outer wall of the glue brushing roller 5 can adsorb the glue inside the glue box 19. Then, a plurality of third push rods 22 are used to push the glue scraping plate 23 to slide inside the rectangular slot 21, so that one side of the glue scraping plate 23 contacts the outer wall of the glue brushing roller 5, and the excess glue on the outer wall of the glue brushing roller 5 can be scraped off. By using the contact between the composite tape 4 and the glue brushing roller 5, the glue can be evenly adhered to the outer wall of the composite tape 4. With the movement of the composite tape 4 and the rotation of the glue brushing roller 5, the glue brushing work of the composite tape 4 can be completed. When it is necessary to replace the glue brushing roller 5, first, the glue inside the glue box 19 is evacuated through the diversion tube 20. Then, the first push rod 13 is used to push the slider 9 to slide inside the opening slot 8, so that the insertion block 11 is disengaged from the slot 12, enabling the staff to easily remove the glue brushing roller 5. Then, a new glue brushing roller 5 is placed between the two transmission rods 10. By retracting the first push rod 13, the insertion block 11 can be driven to re-insert into the slot 12, fixing the glue brushing roller 5 between the two transmission rods 10 and completing the replacement work of the glue brushing roller 5. By adopting the above method, it is convenient for the staff to replace the glue brushing roller 5, reducing physical consumption and time consumption, improving the glue brushing efficiency of the composite of environmental protection packaging bags, and enhancing the practicability and working efficiency of the device.

[0028] Furthermore, as Figure 3 shown, a plurality of drive motors 2 are fixedly connected to both sides of the machine body 1, and one end of the output shaft of each of the plurality of drive motors 2 is fixedly connected to one end of a guide roller 3. One side of one drive motor 2 is fixedly connected to one slider 9, and one end of the output shaft of the drive motor 2 is fixedly connected to one end of the transmission rod 10. One side of the bottom of each opening slot 8 is provided with a positioning slot 15, and a sliding rod 14 is slidably connected to the inner wall of each positioning slot 15. One end of each sliding rod 14 is fixedly connected to one side of the slider 9.

[0029] During operation, the plurality of drive motors 2 can drive the plurality of guide rollers 3 to rotate, ensuring the stability of the conveyance of the composite tape 4. Then, the output shaft of one drive motor 2 drives the transmission rod 10 to rotate, so that the glue brushing roller 5 can rotate synchronously with the plurality of guide rollers 3, thereby ensuring the glue brushing efficiency of the composite tape 4. When the first push rod 13 is used to push the slider 9 to move, the sliding rod 14 can be driven to slide inside the positioning slot 15. The sliding rod 14 can prevent the slider 9 from being misaligned during movement, ensuring the stability of the structure.

[0030] Furthermore, as Figure 4 shown, a second push rod 17 is fixedly connected to the inner wall of the top of each opening groove 8. One end of each second push rod 17 is fixedly connected to a rectangular block 16. Each rectangular block 16 is slidably connected to the inner wall of the opening groove 8 through the second push rod 17. A reset spring 18 is fixedly connected to one side of the top of each rectangular block 16. Each reset spring 18 is sleeved on the outside of the second push rod 17. A pressure rod 6 is rotatably connected to the inner walls of the two rectangular blocks 16. The outer wall of the pressure rod 6 is rotatably connected to the outer wall of the composite tape 4. And the pressure rod 6 is horizontally arranged between the two rectangular blocks 16 and the glue brush roller 5. A flattening roller 7 is arranged on one side of the pressure rod 6. Both ends of the flattening roller 7 are rotatably connected to the inner wall of the machine body 1. And one end of the flattening roller 7 is fixedly connected to the output shaft of a driving motor 2. The outer wall of the flattening roller 7 is rotatably connected to one side of the composite tape 4.

[0031] During operation, by starting the second push rod 17, the second push rod 17 is used to push the rectangular block 16 to slide inside the opening groove 8, which can drive the pressure rod 6 to move horizontally on the top of the glue brush roller 5, facilitating the passage of the composite tape 4 through between the glue brush roller 5 and the pressure rod 6. And as the pressure rod 6 drops, the composite tape 4 can be pressed, making the composite tape 4 closely attached to the outside of the glue brush roller 5, so that the glue can be stably pasted on one side of the composite tape 4, ensuring the glue brushing effect of the composite tape 4. The reset spring 18 can improve the seismic efficiency of the structure, and the elastic force of the reset spring 18 can be used to push the pressure rod 6 into contact with one side of the glue brush roller 5, which can improve the service life and practicability of the structure. The output shaft of a driving motor 2 can drive the flattening roller 7 to rotate. By the rotation of the outer wall of the flattening roller 7 and the composite tape 4, the glue adhered to one side of the composite tape 4 can be flattened, improving the composite effect of the composite tape 4.

[0032] Working principle: Pass the composite tape 4 through multiple guide rollers 3, and then start the second push rod 17. Use the second push rod 17 to push the rectangular block 16 to slide inside the open slot 8. As the pressure rod 6 drops, the composite tape 4 can be pressed, making the composite tape 4 closely adhere to the outer side of the glue brushing roller 5. When it is necessary to brush glue on the composite tape 4, drive the guide roller 3 to rotate through the drive motor 2, so that the composite tape 4 moves inside the machine body 1. Then, by connecting the diversion pipe 20 with the glue supply system, the glue can circulate inside the glue box 19. Drive the transmission rod 10 to rotate by the output shaft of a drive motor 2, so that the glue brushing roller 5 can rotate synchronously with multiple guide rollers 3. The outer wall of the glue brushing roller 5 can adsorb the glue inside the glue box 19. Then, use multiple third push rods 22 to push the glue scraping plate 23 to slide inside the rectangular slot 21, so that one side of the glue scraping plate 23 contacts the outer wall of the glue brushing roller 5, and the excess glue on the outer wall of the glue brushing roller 5 can be scraped off. Then, due to the contact between the composite tape 4 and the glue brushing roller 5, the glue is evenly adhered to the outer wall of the composite tape 4. Then, drive the flattening roller 7 to rotate by the output shaft of the drive motor 2, and the glue adhered to one side of the composite tape 4 can be flattened, completing the glue brushing work of the composite tape 4. When it is necessary to replace the glue brushing roller 5, first evacuate the glue inside the glue box 19 through the diversion pipe 20, and then use the first push rod 13 to push the slider 9 to slide inside the open slot 8, driving the sliding rod 14 to slide inside the positioning slot 15 to prevent the slider 9 from being misaligned during movement. Make the insertion block 11 disengage from the insertion slot 12, and the glue brushing roller 5 can be easily removed. Then, place the new glue brushing roller 5 between the two transmission rods 10, and then use the retraction of the first push rod 13 to drive the insertion block 11 to re-insert into the insertion slot 12, so that the glue brushing roller 5 is fixed between the two transmission rods 10, completing the replacement work of the glue brushing roller 5.
