Description

Technical Field

[0001] This utility model relates to the field of adhesive tape production technology, and more specifically, to an adhesive coating device for adhesive tape production. Background Technology

[0002] Adhesive tape is a strip-shaped material composed of a substrate and an adhesive. It is mainly used to bond, fix, or protect items. During the production process, adhesive tape usually requires the use of an adhesive applicator to apply adhesive to the surface of the tape.

[0003] Existing adhesive application devices typically spray adhesive directly onto the surface of the tape using a nozzle. This process results in more adhesive being sprayed onto the central portion of the tape closer to the nozzle, while less adhesive is sprayed onto the edges farther from the nozzle, leading to uneven adhesive distribution on the tape and affecting the tape's forming quality. Utility Model Content

[0004] This utility model provides a surface coating device for tape production, which solves the technical problem that the existing coating devices usually spray glue onto the surface of the tape through a spray nozzle, resulting in uneven glue distribution on the tape and affecting the forming quality of the tape.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows: A tape production surface coating device includes a machine body with an inlet and an outlet on both sides. A coating roller is rotatably connected inside the machine body. A first motor is mounted on the outside of the machine body, and the end of the coating roller is connected to one end of the output shaft of the first motor. The device also includes a set of glue storage tanks, one end of which is connected to a first pump pipe. The end of the first pump pipe extends into the interior of the machine body and is fixedly connected to a dispensing pipe. A spray nozzle facing the coating roller is provided on the dispensing pipe. A movable plate is provided inside the machine body, and a connecting rod is fixedly connected to the movable plate. The end of the connecting rod is connected to an arc-shaped scraper that abuts against the surface of the coating roller. A reciprocating drive assembly acting on the movable plate is also provided inside the machine body.

[0006] Furthermore, the reciprocating drive assembly includes a second motor mounted on one side of the machine body, a rotating arm connected to one end of the output shaft of the second motor, a pin disposed at the end of the rotating arm, and a strip groove opened inside the movable plate for one end of the pin to be inserted. A sliding rod is fixedly connected inside the machine body, and sliding sleeves are fixedly connected to both sides of the movable plate. The sliding sleeves are slidably fitted onto the surface of the sliding rod.

[0007] Furthermore, several sets of the adhesive nozzles are equidistantly distributed on the dispensing tube.

[0008] Furthermore, a pressure roller is rotatably connected inside the machine body above the glue-applying roller, and meshing gears are connected between the ends of the glue-applying roller and the pressure roller.

[0009] Furthermore, a collection trough is provided inside the machine body below the glue coating roller, and a second pump pipe is connected between the collection trough and the glue storage tank.

[0010] Furthermore, a heating rod is installed inside the glue storage tank, and a third motor is installed at the top of the glue storage tank. One end of the output shaft of the third motor extends into the interior of the glue storage tank and is fixedly connected to a stirring shaft.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the glue is sprayed onto the surface of the coating roller through the spray nozzle on the dispensing pipe, and the reciprocating drive assembly can drive the movable plate to move the arc-shaped scraper horizontally back and forth. During this process, the arc-shaped scraper can spread the glue sprayed onto the surface of the coating roller evenly, so that the glue can be evenly distributed on the coating roller before being applied to the tape. When the coating roller rotates under the drive of the first motor, it can make the coating roller roll into contact with the forward conveyed tape, thereby evenly applying the glue on the surface of the coating roller to the surface of the tape, effectively ensuring the forming quality of the tape.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0017] Please see Figure 1-6A tape production surface coating device includes a machine body 1, with an inlet 2 and an outlet 3 on both sides of the machine body 1. The tape extends into the machine body 1 through the inlet 2 and extends out through the outlet 3. A coating roller 4 is rotatably connected inside the machine body 1. A first motor 5 is mounted on the outside of the machine body 1. The end of the coating roller 4 is connected to one end of the output shaft of the first motor 5. When the tape passes through the inside of the machine body 1, its surface will come into contact with the coating roller 4. The first motor 5 can drive the coating roller 4 to rotate, thus coordinating with the tape to move forward. The device also includes a set of glue storage tanks 6, which are used to store glue. One end of the glue storage tank 6 is connected to a first pump pipe 7, the end of which extends into the inside of the machine body 1 and is fixedly connected to a... The dispensing pipe 8 is equipped with a spray nozzle 9 facing the coating roller 4. Several sets of spray nozzles 9 are equidistantly distributed on the dispensing pipe 8. The glue inside the glue storage tank 6 can be pumped to the dispensing pipe 8 through the first pump pipe 7 and sprayed onto the surface of the coating roller 4 through the several sets of spray nozzles 9. The machine body 1 is equipped with a movable plate 10. A connecting rod 11 is fixedly connected to the movable plate 10. An arc-shaped scraper 12 is connected to the end of the connecting rod 11. The arc-shaped scraper 12 abuts against the surface of the coating roller 4. The machine body 1 is also equipped with a reciprocating drive assembly that acts on the movable plate 10. The reciprocating drive assembly can drive the movable plate 10 to perform horizontal reciprocating motion, thereby driving the arc-shaped scraper 12 to adhere to the surface of the coating roller 4 and perform reciprocating scraping.

[0018] In use, the adhesive tape to be coated passes through the inside of the machine body 1 through the inlet 2 and outlet 3. The tape passing through the inside of the machine body 1 will come into contact with the surface of the coating roller 4. The adhesive is sprayed onto the surface of the coating roller 4 through the spray nozzle 9 on the dispensing pipe 8. When the coating roller 4 rotates under the drive of the first motor 5, it can make the coating roller 4 roll into contact with the forward conveyed tape, thereby applying the adhesive on the surface of the coating roller 4 to the surface of the tape. In addition, the reciprocating drive assembly can drive the movable plate 10 to drive the arc scraper 12 to move horizontally back and forth. During this process, the arc scraper 12 can spread the adhesive sprayed onto the surface of the coating roller 4 evenly, so that the adhesive can be evenly distributed on the coating roller 4 before being applied to the tape, thereby ensuring that the adhesive can be evenly applied to the surface of the tape.

[0019] For further details, please refer to Figure 1-6The reciprocating drive assembly includes a second motor 13 mounted on one side of the body 1, a rotating arm 14 connected to one end of the output shaft of the second motor 13, a pin 15 disposed at the end of the rotating arm 14, and a strip groove 16 opened inside the movable plate 10 for one end of the pin 15 to be inserted. A slide rod 17 is fixedly connected inside the body 1, and slide sleeves 18 are fixedly connected to both sides of the movable plate 10. The slide sleeves 18 are slidably fitted onto the surface of the slide rod 17. The output shaft of the second motor 13 can drive the rotating arm 14 to rotate, thereby driving the pin 15 at the end of the rotating arm 14 to perform circumferential motion. During this process, the pin 15 will reciprocate inside the strip groove 16, so that the movable plate 10 can be subjected to a horizontal reciprocating drive, thereby driving the movable plate 10 to slide horizontally along the slide rod 17.

[0020] For further details, please refer to Figure 1-6 Inside the machine body 1, a pressure roller 19 is rotatably connected above the coating roller 4. When the tape passes through the coating roller 4, the pressure roller 19 presses the tape tightly onto the coating roller 4, ensuring that the tape is in close contact with the surface of the coating roller 4 and thus guaranteeing the coating effect on the tape surface. In addition, a meshing gear 20 is connected between the ends of the coating roller 4 and the pressure roller 19. When the coating roller 4 rotates, the gear 20 drives the pressure roller 19 to rotate synchronously, so that the coating roller 4 and the pressure roller 19 can rotate synchronously in coordination with the movement of the tape, avoiding the pressure roller 19 from obstructing the movement of the tape and thus ensuring the stability of the tape movement process.

[0021] For further details, please refer to Figure 1-6 Inside the machine body 1, below the glue-applying roller 4, there is a collection tank 21. During the glue-applying process, excess glue remaining on the glue-applying roller 4 will drip down and be collected inside the collection tank 21. A second pump pipe 22 is connected between the collection tank 21 and the glue storage tank 6. The glue inside the collection tank 21 can be pumped back to the glue storage tank 6 through the second pump pipe 22, thereby realizing the recycling of excess glue and avoiding glue waste.

[0022] For further details, please refer to Figure 1-6 The glue storage tank 6 is equipped with a heating rod 23, which heats the glue inside the storage tank 6, ensuring that the glue is melted before being applied to the tape. A third motor 24 is installed at the top of the glue storage tank 6. One end of the output shaft of the third motor 24 extends into the interior of the glue storage tank 6 and is fixedly connected to a stirring shaft 25. As the output shaft of the third motor 24 drives the stirring shaft 25 to rotate, it can stir the glue inside the glue storage tank 6, so that the glue can be evenly heated by the heating rod 23, further preventing the glue inside the storage tank 6 from solidifying.

[0023] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
