Abstract
Description
Technical Field
[0001] This utility model relates to an adhesive application device, specifically an adhesive application device for uniform application. Background Technology
[0002] Pressure-sensitive adhesive tape is a special type of tape made by applying a special adhesive (pressure-sensitive adhesive) to a strip-shaped substrate. It consists of pressure-sensitive adhesive, a substrate, a primer, and a backing agent. The production process of pressure-sensitive adhesive tape requires coating the substrate with the adhesive, thus necessitating the use of an adhesive application device to ensure uniform coating.
[0003] When the current uniform gluing device applies the adhesive to the substrate, the adhesive tends to remain on the side of the substrate, which can lead to uneven winding and affect its use when the substrate is rolled up. Utility Model Content
[0004] The main objective of this disclosure is to provide a uniform adhesive application device to effectively solve the problems raised by the inventors in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A uniform gluing device includes a base. Two connecting discs are movably mounted on the upper left side of the base. A substrate roll is positioned between the two connecting discs, and a substrate body is mounted on the substrate roll. A first fixing frame and a second fixing frame are fixedly installed in the middle of the upper end of the base. A clamping roller and a gluing roller are rotatably mounted inside the first fixing frame. A storage cylinder is fixedly mounted on the upper end of the first fixing frame via a support rod. An injection port is opened at the upper end of the storage cylinder, and an output pump is fixedly mounted at its lower end. The input end of the output pump communicates with the storage cylinder, and a gluing plate is fixedly mounted at its output end. Multiple gluing holes are opened at the lower end of the gluing plate. Two scraper plates are movably mounted inside the second fixing frame. The two scraper plates are positioned front and rear... The base is symmetrically arranged with two movably mounted vertical plates near the right side of its upper end. A take-up drum is positioned between the two vertical plates. The substrate body passes through the clamping roller and the coating roller, and also passes through the two scraper plates, and is wound around the take-up drum. The adhesive in the storage cylinder is output to the coating plate by the output pump, and then discharged onto the coating roller through multiple coating holes. At this time, rotating the take-up drum moves the substrate body, thereby causing the substrate body to drive the coating roller to rotate. The coating roller performs adhesive treatment, and then the substrate body passes between the two scraper plates. The two scraper plates smooth the two sides of the substrate body, removing excess adhesive and making the winding neater.
[0007] Preferably, a bidirectional screw is rotatably installed near the left side of the base, and a slide rod is fixedly installed thereon. Slide plates are threaded onto the threads on both sides of the bidirectional screw, and both slide plates are slidably connected to the slide rod. Openings are provided on the upper left side of the base near both the front and rear ends. The two connecting discs are respectively fixedly installed on the upper ends of the two slide plates by vertical rods. A rocker wheel is rotatably installed on the front side of the base. The rocker wheel is fixedly connected to the rotating shaft of the bidirectional screw. By rotating the bidirectional screw through the rocker wheel, the two slide plates slide towards each other on the slide rod, thereby moving the two connecting discs towards each other through the vertical rod. This allows for convenient clamping, limiting, or disassembly of the substrate roll.
[0008] Preferably, the two connecting discs are rotatably mounted with connecting rings on one side close to each other via bearing components. The inner sides of the two connecting rings abut against the front and rear ends of the substrate roll, respectively. The connecting rings facilitate the fixed installation of the substrate roll, and the bearing components allow the substrate roll to rotate for use.
[0009] Preferably, a bidirectional screw rod 2 is rotatably installed near the upper end of the fixed frame 2. Connecting blocks are threaded onto the threads on both sides of the bidirectional screw rod 2. A limiting rod is fixedly installed near the lower end of the fixed frame 2. Two connecting blocks are slidably installed on the limiting rod. Several connecting blocks are divided into two groups and arranged symmetrically above and below each other. Two scraping plates are fixedly installed between the two groups of connecting blocks respectively. A rocker wheel 2 is rotatably installed on the front side of the fixed frame 2. The rocker wheel 2 is fixedly connected to the rotating shaft of the bidirectional screw rod 2. By rotating the bidirectional screw rod 2 through the rocker wheel 2, the two connecting blocks on the bidirectional screw rod 2 move towards each other, carrying the two scraping plates. At this time, the two connecting blocks on the limiting rod will slide on the limiting rod along with the scraping plates, so that the scraping plates can move smoothly. The two scraping plates can be moved towards each other to adjust the width of the substrate body.
[0010] Preferably, a bidirectional screw rod three is rotatably installed near the right side of the base, and limiting openings are provided on the upper right side of the base near both the front and rear ends. Two vertical plates are respectively threaded onto the threads on both sides of the bidirectional screw rod three, and the two vertical plates are respectively set in the two limiting openings. A rocker wheel three is rotatably installed on the front side of the base. The rocker wheel three is fixedly connected to the rotating shaft of the bidirectional screw rod three. By rotating the bidirectional screw rod three through the rocker wheel three, the two vertical plates move towards each other at the limiting openings, thereby clamping and limiting the winding drum or disassembling it for use.
[0011] Preferably, the two vertical plates are rotatably mounted with connecting rings two via bearing components two on one side close to each other. The inner sides of the two connecting rings two respectively abut against the front and rear ends of the take-up drum. A take-up motor is fixedly mounted on the outer side of one of the vertical plates. The output end of the take-up motor is fixedly connected to one of the connecting rings two. The take-up drum is clamped by the two connecting rings two. Then, the take-up motor drives one of the connecting rings two to rotate. The bearing components two cause the two connecting rings two to rotate with the take-up drum to wind up the substrate body.
[0012] In view of this, compared with the prior art, the beneficial effects of this utility model are:
[0013] In this application, by setting two scraper plates, when the substrate body is coated with adhesive and rolled up, the substrate body will pass between the two scraper plates after being coated with adhesive. The two scraper plates will clean the two sides of the substrate body, and scrape off the excess adhesive on the two sides to make the substrate body roll up more neatly. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-6 The present invention provides the following embodiments:
[0023] A uniform gluing device includes a base 1. Two connecting discs 7 are movably mounted on the upper left side of the base 1, and a substrate roll 10 is positioned between the two connecting discs 7. A substrate body 11 is mounted on the substrate roll 10. A first fixing frame 12 and a second fixing frame 20 are fixedly mounted in the middle of the upper end of the base 1. A clamping roller 13 and a gluing roller 14 are rotatably mounted inside the first fixing frame 12. A storage cylinder 16 is fixedly mounted on the upper end of the first fixing frame 12 via a support rod 15. The storage cylinder 16 has an injection port at its upper end and an output pump 17 is fixedly mounted on its lower end. The input end of the output pump 17 communicates with the storage cylinder 16, and a gluing plate 18 is fixedly mounted on its output end. The lower end of the gluing plate 18 has multiple gluing holes 19. Two scraper plates 24 are movably mounted inside the second fixing frame 20, and the two scraper plates 24 are symmetrically arranged front and back. Two vertical plates 27 are movably provided on the upper end of the base 1 near the right side. A take-up drum 32 is provided between the two vertical plates 27. The substrate body 11 passes through the clamping roller 13 and the coating roller 14, and passes through the two scraper plates 24. It is wound on the take-up drum 32. The glue in the storage cylinder 16 is output to the coating plate 18 by the output pump 17, and then discharged onto the coating roller 14 through multiple coating holes 19. At this time, the substrate body 11 is moved by rotating the take-up drum 32, thereby causing the substrate body 11 to drive the coating roller 14 to rotate. The coating roller 14 performs glue treatment. Then the substrate body 11 passes between the two scraper plates 24. The two scraper plates 24 scrape the two sides of the substrate body 11 to flatten it, which can remove excess glue and make the winding more neat.
[0024] Specifically, a bidirectional screw 2 is rotatably installed near the left side of the base 1, and a slide rod 3 is fixedly installed thereon. Slide plates 4 are threaded onto the threads on both sides of the bidirectional screw 2, and both slide plates 4 are slidably connected to the slide rod 3. Openings are made on the upper left side of the base 1 near both the front and rear ends. Two connecting plates 7 are fixedly installed on the upper ends of the two slide plates 4 by vertical rods 6. A rocker wheel 5 is rotatably installed on the front side of the base 1. The rocker wheel 5 is fixedly connected to the rotating shaft of the bidirectional screw 2. By rotating the bidirectional screw 2 through the rocker wheel 5, the two slide plates 4 slide towards each other on the slide rod 3, thereby moving the two connecting plates 7 towards each other through the vertical rod 6. This allows for convenient clamping, limiting, or disassembly of the substrate roll 10.
[0025] Specifically, the two connecting discs 7 are close to each other and are rotatably mounted with connecting rings 9 via bearing components 8. The inner sides of the two connecting rings 9 respectively abut against the front and rear ends of the substrate roll 10. The connecting rings 9 facilitate the fixed installation of the substrate roll 10, and the substrate roll 10 is rotated for use via the bearing components 8.
[0026] Specifically, a bidirectional screw 21 is rotatably installed near the upper end inside the fixed frame 20. Connecting blocks 23 are threaded onto the threads on both sides of the bidirectional screw 21. A limiting rod 22 is fixedly installed near the lower end of the fixed frame 20. Two connecting blocks 23 are slidably installed on the limiting rod 22. Several connecting blocks 23 are divided into two groups and arranged symmetrically above and below each other. Two scraping plates 24 are fixedly installed between the two groups of connecting blocks 23. A rocker wheel 25 is rotatably installed on the front side of the fixed frame 20. The rocker wheel 25 is fixedly connected to the rotating shaft of the bidirectional screw 21. By rotating the bidirectional screw 21 through the rocker wheel 25, the two connecting blocks 23 on the bidirectional screw 21 move towards each other, along with the two scraping plates 24. At this time, the two connecting blocks 23 on the limiting rod 22 will slide on the limiting rod 22 along with the scraping plates 24, so that the scraping plates 24 can move smoothly. The two scraping plates 24 are moved towards each other to adjust the width of the substrate body 11.
[0027] Specifically, a bidirectional screw 26 is rotatably installed near the right side inside the base 1, and limiting ports 28 are opened on the upper right side of the base 1 near both the front and rear ends. Two vertical plates 27 are threaded onto the threads on both sides of the bidirectional screw 26, and the two vertical plates 27 are respectively set in the two limiting ports 28. A rocker wheel 29 is rotatably installed on the front side of the base 1. The rocker wheel 29 is fixedly connected to the rotating shaft of the bidirectional screw 26. By rotating the bidirectional screw 26 through the rocker wheel 29, the two vertical plates 27 move towards each other at the limiting ports 28, thereby clamping and limiting the winding drum 32 or disassembling it for use.
[0028] Specifically, two vertical plates 27 are close to each other on one side, and connecting rings 31 are rotatably mounted on one side via bearing 30. The inner sides of the two connecting rings 31 abut against the front and rear ends of the take-up drum 32, respectively. A take-up motor 33 is fixedly mounted on the outer side of one of the vertical plates 27. The output end of the take-up motor 33 is fixedly connected to one of the connecting rings 31. The take-up drum 32 is clamped by the two connecting rings 31. Then, the take-up motor 33 drives one of the connecting rings 31 to rotate. The bearing 30 causes the two connecting rings 31 to rotate with the take-up drum 32 to take up the substrate body 11.
[0029] The working principle of this utility model is as follows: First, the substrate roll 10 is placed between two connecting rings 9. The double-sided screw 2 is rotated by the rocker wheel 5 to bring the two sliding plates 4 closer together on the sliding rod 3, thereby causing the two connecting discs 7 to move closer together. This brings the two ends of the substrate roll 10 into contact with the two connecting rings 9. Then, the substrate body 11 on the substrate roll 10 is pulled out and passes between the clamping roller 13 and the coating roller 14, then passes between the two scraper plates 24 and is wound onto the take-up drum 32. Next, the double-sided screw 21 is rotated by the rocker wheel 25, causing the two connecting blocks 23 on the double-sided screw 21 to move closer together along with the two scraper plates 24. Simultaneously, the two connecting blocks 23 on the limiting rod 22 slide along with the scraper plates 24 on the limiting rod 22. At this time, the two scraper plates... 24 will smoothly move and contact the two sides of the substrate body 11, and then inject pressure-sensitive adhesive into the storage cylinder 16. At this time, the take-up motor 33 can be turned on to drive the connecting ring 31, so that the two connecting rings 31 drive the take-up cylinder 32 to rotate through the bearing 30, thereby driving the substrate body 11 to move. At the same time, the adhesive in the storage cylinder 16 is output to the coating plate 18 through the output pump 17, and then discharged to the coating roller 14 through multiple coating holes 19. At this time, when the substrate body 11 moves, it will drive the coating roller 14 to rotate, and the coating roller 14 will apply adhesive to the substrate body 11. After the adhesive is applied, the substrate body 11 will pass through two scraper plates 24, and the two scraper plates 24 will scrape the two sides of the substrate body 11 flat. After the treatment, it can be wound up by the take-up cylinder 32.
