Description

Technical Field

[0001] This application relates to the technical field of adhesive coating, and particularly to a rubber adhesive coating device. Background Art

[0002] Rubber adhesives are a type of adhesives formulated with synthetic rubbers such as chloroprene, nitrile, butyl silicone rubber, polysulfide, or natural rubber as the main materials. It has excellent elasticity and is suitable for bonding soft materials or materials with a large difference in thermal expansion coefficients, such as the bonding between rubber and rubber, rubber and metal, plastics, leather, wood, etc. It has a wide range of applications in sectors such as aircraft manufacturing, automotive manufacturing, construction, light industry, and rubber product processing. Rubber adhesives are mainly divided into two categories: structural adhesives and non-structural adhesives. Structural adhesives are further divided into solvent-based liquid adhesives and adhesive film tapes, which are mostly composite systems. Non-structural rubber adhesives can be divided into two major categories: solution type and emulsion type, among which solution-type rubber adhesives (abbreviated as rubber adhesive liquids) are the main type.

[0003] The existing Chinese patent with the publication number CN218796910U discloses a rubber adhesive coating device, including a device main body. Two guide rollers are installed on the device main body, and a film is arranged between the two guide rollers. First mounting plates and second mounting plates are symmetrically installed on the device main body. Two mounting blocks are slidably installed on both the first mounting plate and the second mounting plate. Thus, when it is necessary to adjust the distance between the two coating rollers, by rotating the threaded rod, the driving slider threadedly connected to the threaded rod moves vertically along the threaded rod, thereby driving the sliding block to move vertically. Then, through the sliding block, the two transmission rods are driven to approach or move away from each other along the sliding block, and further, the two horizontal sliding blocks approach or move away from each other, so that the two coating rollers can be driven to approach or move away from each other, making the device adaptable to films of different thicknesses and improving the adaptability of the device.

[0004] However, the above-mentioned coating device has the following disadvantages: The device can adjust the distance between the two coating rollers by setting two mounting blocks. However, before coating the film, dust or impurities may remain on the surface of the film, and these dust and impurities will cause the coating quality to decrease. At the same time, after the coating is completed, air bubbles may remain, unable to ensure the uniformity of the adhesive layer, reducing the uniformity and integrity of the coating layer.

[0005] Therefore, we propose a rubber adhesive coating device to solve this problem.

[0006] The above information disclosed in this background art is only used to increase the understanding of the background art of this application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Utility Model Content

By providing the air bubble removal plate 14 and the fixed column 15, the air bubble removal plate 14 can be driven to pat the film 4 after glue coating, removing the air bubbles on the film 4, ensuring a uniform glue layer, reducing the influence of air bubbles on the adhesion and uniformity of the glue layer, and improving the uniformity and integrity of the glue coating layer.

[0022] Refer to Figures 2-3 , The first driving mechanism includes a first double-headed threaded rod 8, a chain 11, a sprocket 13, and a first motor 7.

[0026] The implementation principle of a rubber adhesive glue application device according to an embodiment of the present application is as follows: When in use, the film 4 can be placed on the glue application device body 1, and then the first motor 7 is started. The first motor 7 drives the first double-headed threaded rod 8 to rotate. The first double-headed threaded rod 8 drives the two first sliders 9 to approach each other. The two first sliders 9 drive the two mounting plates 5 to approach each other. The two mounting plates 5 drive the two cleaning cloths 10 to approach each other to clean both sides of the film 4. The cleaned film 4 is conveyed upward through the guide rollers 2, and then passes through the glue application mechanism 3 for glue application. After the glue is applied, the second motor 18 is started. The second motor 18 drives the two second double-headed threaded rods 16 to rotate. The two second double-headed threaded rods 16 drive the two second sliders 17 to move. The two second sliders 17 drive the two fixing columns 15 to approach or separate from each other.
