[0022] The tensioning device 3 includes a connecting frame 31. A second servo motor 32 is fixedly connected to the outer wall of the connecting frame 31. The output end of the second servo motor 32 is fixedly connected to a driving roller 33. Driving gears 34 are fixedly connected to both ends of the driving roller 33. A coating roller 35 is arranged above the driving roller 33. Before the paper enters the glue applicator roller 6 driven by the first servo motor 2, it first passes through the tensioning device 3. The wound paper is located at one end of the connecting frame 31 away from the glue storage tank 1 and at a slightly lower position. The paper passing through the upper surface of the connecting frame 31 enters between the coating roller 35 and the driving roller 33, and then guides the paper into between the glue applicator roller 6 and the squeezing roller 53. At this time, the paper reaching the glue applicator roller 6 receives the tension force of the driving roller 33, thereby reducing the wrinkles of the paper at the gluing part.

[0023] The coating device 4 includes a glue storage box 42. A movable plate 41 is slidably connected to the outer wall of the bottom of the glue storage box 42. An extension column 43 is fixedly connected to the outer wall of the movable plate 41. A magnetic attraction block 44 is fixedly connected to the outer wall of the extension column 43. The outer wall of the magnetic attraction block 44 is slidably connected to the inner wall of the glue storage box 42 through a movable groove 45, and the movable groove 45 is opened in the wall of the glue storage box 42. A communicating pipe 46 is fixedly connected to the top of the glue storage box 42. A peristaltic pump 47 is fixedly connected to the outer wall of the communicating pipe 46. A leakage hole 48 is opened in the middle of the top of the communicating pipe 46. Before the paper enters the glue applicator roller 6 driven by the first servo motor 2, it first passes through the tensioning device 3. The wound paper is located at one end of the connecting frame 31 away from the glue storage tank 1 and at a slightly lower position. The paper passing through the upper surface of the connecting frame 31 enters between the coating roller 35 and the driving roller 33, and then guides the paper into between the glue applicator roller 6 and the squeezing roller 53. At this time, the paper reaching the glue applicator roller 6 receives the tension force of the driving roller 33, thereby reducing the wrinkles of the paper at the gluing part.

[0024] The outer wall of the communicating pipe 46 is fixedly connected to the inner wall of the glue storage tank 1. The outer wall of the glue storage box 42 is fixedly connected to the outer wall of the connecting frame 31. The outer wall of the connecting frame 31 is fixedly connected to the outer wall of the glue storage tank 1. The inner wall of the connecting frame 31 is rotatably connected to the outer wall of the driving roller 33. The driving gear 34 meshes with the transmission gear 36. Through the communicating pipe 46, the peristaltic pump 47 and the leakage hole 48, the peristaltic pump 47 transports the glue by squeezing the communicating pipe 46 with its own rollers. When moving the glue from the glue storage tank 1 to the glue storage box 42, the glue inside the glue storage box 42 is moved, and the flowing glue avoids the long-term deposition of the glue at the bottom.

The bottom of the fixed frame 51 is fixedly connected to the top of the glue storage tank 1. The outer wall of a glue application roller 6 is rotatably connected to the inner wall of the bottom of the fixed frame 51. The outer wall of the glue application roller 6 is fixedly connected to the output end of the first servo motor 2. By rotating the rotating screw rod 56, the height of the sliding plate 54 is adjusted. The sliding plate 54 slides under the limitation of the limiting plates 55, thereby driving the sliding block 52 below the sliding plate 54 to move. At this time, the sliding block 52 will move along the fixed frame 51 and drive the extrusion roller 53 to move, so as to achieve the purpose of controlling the distance between the extrusion roller 53 and the glue application roller 6.

[0026] Working principle:

[0027] During use, a tensioning device 3 is set so that the paper entering the gluing part is tensioned to prevent the paper from sagging in the natural state, which may cause wrinkles during gluing and affect the gluing coverage area, making the paper gluing more uniform. Before the paper enters the glue application roller 6 driven by the first servo motor 2, it first passes through the tensioning device 3. The wound paper is located at the end of the connecting frame 31 far from the glue storage tank 1 and at a slightly lower position. The paper passing through the upper surface of the connecting frame 31 enters between the coating roller 35 and the driving roller 33, and then the paper is guided into between the glue application roller 6 and the extrusion roller 53. At this time, the paper reaching the glue application roller 6 receives the tension force of the driving roller 33, so that there are fewer wrinkles in the paper at the gluing part, and thus the gluing is more uniform.

[0028] The tensioning device 3 and the coating device 4 are arranged so that both sides of the paper can be coated with glue. At the same time, the coating device 4 is arranged to increase the flow of the glue, so that it is difficult for the glue to deposit. When in use, the peristaltic pump 47 is started. The peristaltic pump 47 squeezes to make the glue move through the connecting pipe 46. When passing through the leakage holes 48, part of the glue drops into the glue storage box 42. When coating is required, the movable plate 41 on the glue storage box 42 is pulled outwards. At this time, the movable plate 41 drives the magnetic attraction block 44 on the extension column 43 to move. Since the port of the magnetic attraction block 44 has magnetism, it can attract the metal glue storage box 42. Before pulling, the movable plate 41 is fixed on the glue storage box 42 through the magnetic attraction block 44, so that the movable plate 41 fits the outer surface of the coating roller 35, making it difficult for the glue to reach the upper surface of the paper through the coating roller 35. After being pulled, the magnetic attraction block 44 moves along the movable groove 45 and adsorbs at the other end of the movable groove 45. Driven by the second servo motor 32, the driving gear 34 rotates, and then the transmission gear 36 rotates synchronously in the opposite direction. At this time, the coating roller 35 will move driven by the transmission gear 36, and the glue will be coated on the upper surface of the paper along the coating roller 35, so that the glue coating mechanism can coat glue on both the upper and lower surfaces of the paper;

[0029] At the same time, when the glue passes through the connecting pipe 46, the peristaltic pump 47 and the leakage holes 48, the peristaltic pump 47 squeezes the connecting pipe 46 through its own rollers to transport the glue. The glue liquid is transmitted through the connecting pipe 46 made of a hose, without contacting the pump body, which can prevent the pump body from being contaminated, and the hose is easy to clean and replace. When moving the glue from the glue storage tank 1 to the glue storage box 42, the glue inside the glue storage box 42 moves, and the flowing glue avoids the long-term deposition of the glue at the bottom, thus ensuring the stability of the viscosity of the glue.

[0030] The adjusting device 5 is arranged so that the glue coating mechanism can use papers of different thicknesses, or apply greater pressure to papers of the same thickness to make the glue coating more uniform. For papers of different thicknesses, the height of the sliding plate 54 can be adjusted by rotating the screw rod 56 movably. The sliding plate 54 slides under the limitation of the limiting plate 55, and then drives the sliding block 52 under the sliding plate 54 to move. At this time, the sliding block 52 will move along the fixed frame 51 and drive the pressing roller 53 to move, so as to achieve the purpose of controlling the distance between the pressing roller 53 and the coating roller 6.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present invention.
