Description

Technical Field

[0001] This utility model relates to the field of self-adhesive coating technology, and in particular to a self-adhesive coating device with self-cleaning function. Background Technology

[0002] Self-adhesive labels, also known as pressure-sensitive labels, are composite materials with paper, film, or special materials as the face stock, adhesive on the back, and silicone-coated release paper as the backing paper. Lamination refers to the process of applying a transparent plastic film to the surface of printed materials through heat pressing, which serves to protect and increase gloss. All self-adhesive labels must undergo lamination treatment before use.

[0003] However, self-adhesive lamination equipment is usually open, and self-adhesive labels can easily adhere to dust or small foreign objects during the transportation process. If the self-adhesive labels are directly laminated, the dust will hinder the tight bonding between the laminating material and the self-adhesive labels, resulting in reduced adhesion and problems such as bubbling and delamination. Therefore, we need to consider how to solve this problem. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a self-cleaning adhesive coating device. By setting up a conveying roller, a cleaning roller, and an output roller, the adhesive drives the adhesion plate to rotate during the conveying process, thereby allowing the adhesion plate to adhere dust and other impurities on the adhesive, thus improving the coating quality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A self-cleaning self-adhesive laminating device includes a worktable. Mounting plates are fixedly connected to both side walls of the worktable. Two conveying rollers are rotatably connected to the side wall of one mounting plate, a cleaning roller is rotatably connected to the side wall of another mounting plate, and an output roller is rotatably connected to the side wall of yet another mounting plate. A support roller is rotatably connected between the two mounting plates. An mounting groove for cooperating with the support roller is provided at the upper end of the worktable. A heating roller is rotatably connected between the two mounting plates. A fixing block is fixedly connected to the upper end of each of the two mounting plates. An unwinding roller is rotatably connected between the two fixing blocks. Two adhesion plates are provided on the outer side wall of the cleaning roller. A retaining ring seat is fixedly connected to both ends of each adhesion plate. A retaining ring is fitted inside each retaining ring seat. Insert blocks are fixedly connected to both side walls of two of the retaining rings. Slots for cooperating with corresponding insert blocks are provided on both side walls of the other two retaining rings. A limiting mechanism for limiting the corresponding insert block is provided in each slot.

[0007] Preferably, each of the limiting mechanisms includes a strip plate, each strip plate is slidably connected to the inner wall of the corresponding slot, a limiting block is fixedly connected to one side of each strip plate, and a limiting groove that cooperates with the corresponding limiting block is opened on the side wall of each insert.

[0008] Preferably, the other side of each strip plate is elastically connected to the inner wall of the corresponding slot by a spring, and a pull rope is fixedly connected to the other side of each strip plate, with the other end of each pull rope extending to the outside.

[0009] Preferably, the inner walls of both adhesive plates are fixedly connected with positioning plates, and the outer wall of the cleaning roller has two positioning grooves that cooperate with the corresponding positioning plates.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-6 A self-cleaning self-adhesive laminating device includes a workbench 1. Mounting plates 2 are fixedly connected to both side walls of the workbench 1. Two conveying rollers 3 are rotatably connected to the side wall of one mounting plate 2, a cleaning roller 4 is rotatably connected to the side wall of another mounting plate 2, and an output roller 5 is rotatably connected to the side wall of yet another mounting plate 2. A support roller 6 is rotatably connected between the two mounting plates 2. An installation groove for the support roller 6 is provided at the upper end of the workbench 1. A heating roller 7 is rotatably connected between the two mounting plates 2, allowing the self-adhesive to adhere to the two conveying rollers 3 and the cleaning roller 4. The adhesive is conveyed through the output roller 5 and then passed between the support roller 6 and the heating roller 7. The upper ends of the two mounting plates 2 are fixedly connected to the fixing blocks 8, and the unwinding roller 9 is rotatably connected between the two fixing blocks 8. The film is fixed on the unwinding roller 9. One end of the film is wrapped around the heating roller 7 and attached to the adhesive. Then, the film is pressed onto the adhesive by the rotation of the support roller 6 and the heating roller 7, thus realizing the film coating operation of the adhesive. The side wall of the other mounting plate 2 is provided with a control panel, which is the prior art and will not be described in detail here.

[0024] The cleaning roller 4 has two adhesive plates 10 on its outer wall. Both adhesive plates 10 are arc-shaped and cooperate with the cleaning roller 4. During the conveying of the self-adhesive, the two adhesive plates 10 rotate, causing them to adhere dust and other impurities from the surface of the self-adhesive. This prevents dust and other impurities from affecting the tight bond between the self-adhesive and the laminating material, improving the lamination quality. Each end of the two adhesive plates 10 is fixedly connected to a retaining ring seat 11. Each retaining ring seat 11 contains a fixing ring 12. Two side walls of the two fixing rings 12 are fixedly connected to inserts 13. The two side walls of the other two fixing rings 12 are provided with slots 14 that mate with the corresponding inserts 13. Each slot 14 contains a... The limiting mechanism for limiting the corresponding insertion block 13 includes a strip plate 15. Each strip plate 15 is slidably connected to the inner wall of the corresponding slot 14. A limiting block 16 is fixedly connected to one side of each strip plate 15. Each insertion block 13 has a limiting groove 17 on its side wall that cooperates with the corresponding limiting block 16. By inserting multiple limiting blocks 16 into the corresponding limiting grooves 17, a fixed connection is achieved between every two cooperating fixing rings 12, thereby fixing the two adhesive plates 10 onto the cleaning roller 4. The other side of each strip plate 15 is elastically connected to the inner wall of the corresponding slot 14 through a spring 18. A pull rope 19 is fixedly connected to the other side of each strip plate 15, and the other end of each pull rope 19 extends to the outside.

[0025] The inner walls of both adhesive plates 10 are fixedly connected to positioning plates 20. The outer wall of the cleaning roller 4 has two positioning grooves 21 that mate with the corresponding positioning plates 20. By inserting the two positioning plates 20 into the corresponding positioning grooves 21, the two adhesive plates 10 are initially positioned and installed. Slide grooves 22 are provided on opposite sides of both mounting plates 2. A reciprocating screw 23 is rotatably connected between the inner walls of the two sides of one slide groove 22, and a guide rod 24 is fixedly connected between the inner walls of the two sides of the other slide groove 22. Each slide groove 22 is equipped with a sliding... The moving plate 25 has one sliding plate 25 threadedly connected to the reciprocating screw 23 and the other sliding plate 25 slidably connected to the guide rod 24. A pressure roller 26 is rotatably connected between the two sliding plates 25. A motor 27 is installed on the side wall of one of the mounting plates 2. The output shaft of the motor 27 extends into the interior of one of the slide grooves 22 and is fixedly connected to one end of the reciprocating screw 23. The pressure roller 26 is moved back and forth to compact the self-adhesive after lamination, thereby eliminating gaps or air bubbles and making the surface of the self-adhesive after lamination smoother.

[0026] In this invention, during use, the device is controlled via a control panel to allow the self-adhesive adhesive to be conveyed through two conveying rollers 3, a cleaning roller 4, and an output roller 5. During the conveying process, the self-adhesive adhesive will drive the cleaning roller 4 and its external adhesive plate 10 to rotate. The rotating adhesive plate 10 will adhere to dust and other impurities on the surface of the self-adhesive adhesive, thereby preventing dust and other impurities from affecting the tight bond between the self-adhesive adhesive and the coating material. Then, the self-adhesive adhesive is passed between the support roller 6 and the heating roller 7, while the coating material is fixed on the unwinding roller 9. One end of the coating material is wrapped around the heating roller 7 and attached to the self-adhesive adhesive. Then, the rotation of the support roller 6 and the heating roller 7 presses the coating material onto the self-adhesive adhesive, thus realizing the coating operation of the self-adhesive adhesive.

[0027] When the adhesive plate 10 needs to be replaced, the pull rope 19 can be pulled to move the strip plate 15, thereby causing the limiting block 16 to leave the limiting groove 17, releasing the limiting of the insert block 13. Then, the two adhesive plates 10 and multiple fixing rings 12 can be removed. To install a new adhesive plate 10, the positioning plates 20 on the two adhesive plates 10 can be inserted into the corresponding positioning grooves 21, and then two of the fixing rings 12 can be inserted into the corresponding retaining ring seats 11. Pulling the multiple pull ropes 19 on the two fixing rings 12 causes the multiple strip plates 15 to move with the corresponding limiting blocks 16. At this time, the multiple springs 18 are in a compressed state. Without releasing the pull ropes, the multiple insert blocks 13 on the other two fixing rings 12 can be inserted into the corresponding slots 14. Then, the multiple pull ropes 19 can be released. Under the elastic action of the multiple springs 18, the multiple limiting blocks 16 can be inserted into the corresponding limiting grooves 17, realizing the fixed connection between the multiple fixing rings 12. This realizes the replacement of the adhesive plate 10. In this way, the removal and installation of the adhesive plate 10 are convenient and simple.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
