Description

Technical Field

[0001] This utility model relates to the field of coating technology, and in particular to a UV-curable release paper coating uniform coating device. Background Technology

[0002] The UV-curable release paper coating uniform coating equipment is a key piece of equipment specifically developed for the release paper production process. Release paper is widely used in many fields such as tapes, labels, food packaging, and medical and health products, and its surface needs to be coated with a UV-curable coating with anti-stick properties. This equipment aims to accurately and uniformly coat the coating onto the release paper surface and achieve rapid curing through ultraviolet irradiation, thereby efficiently producing release paper products that meet quality standards.

[0003] Existing UV-curable release paper coating uniform coating equipment often lacks effective anti-deviation measures. Once the release paper shifts, it easily affects the coating quality. Furthermore, in terms of adjusting the coating thickness, traditional equipment typically struggles to flexibly and conveniently adjust the distance between the extrusion roller and the coating roller. This makes it impossible to quickly and accurately adjust the coating thickness to meet different process requirements and product demands, impacting production flexibility and efficiency, and hindering the ability to meet diverse market demands. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing release paper coating uniform coating equipment lacks effective anti-deviation measures, and once the release paper deviates, it easily affects the coating quality. Therefore, a UV-curable release paper coating uniform coating equipment is proposed.

A first motor 11 is fixedly connected to the surface of the machine body 1 near both ends. The output end is fixedly connected to one end of the rotating rod 7, which can enable the first motor 11 to drive the rotating rod 7 to rotate; the coating assembly 12 includes a rotating column 121, which is located inside the lower square groove 4. Both ends of the rotating column 121 penetrate the inner walls of both ends of the groove 5 and are rotatably connected to their bearings. A coating roller 122 is fitted and fixedly connected to the surface of the rotating column 121. A U-shaped plate 124 is provided above the coating roller 122.

The surface of the machine body 1 A second motor 123 is fixedly connected, and the output end of the second motor 123 is fixedly connected to one end of the rotating column 121. This allows the hydraulic cylinder 126 to push the U-shaped plate 124 down. The descent of the U-shaped plate 124 causes the extrusion roller 125 to extrude the release paper. At the same time, the distance between the release paper and the coating roller 122 can be adjusted. Then, the second motor 123 drives the rotating column 121 to rotate, which in turn drives the coating roller 122 to coat the release paper. The anti-deviation assembly 13 includes two bidirectional screws 131, which are located on both sides of the coating assembly 12. Both ends of the bidirectional screws 131 are... A rotating component 134 is fixedly connected to one end of a bidirectional screw 131 that penetrates the machine body 1 and is rotatably connected to its bearing. Limiting plates 133 are threadedly fitted onto both ends of the bidirectional screw 131 and connected to it. Limiting rollers 132 are provided above the bidirectional screw 131. Both ends of the limiting rollers 132 penetrate the limiting plates 133 and are slidably connected to them. Both ends of the limiting rollers 132 are rotatably connected to the bearings on the inner wall of the machine body 1. This allows the rotating component 134 to rotate, which in turn drives the bidirectional screw 131 to rotate. The rotation of the bidirectional screw 131 drives the limiting plates 133 to move, allowing the surface of the limiting plates 133 to adhere to the edge of the release paper, thus limiting the release paper.

[0026] Working principle: The release paper is passed through the space between the two conveying rollers 8 and above the limiting roller 132 at one end, and can also pass between the extrusion roller 125 and the coating roller 122. Then, the release paper is passed through the rotating rollers 10 and discharged from the other end between the conveying rollers 8. During this process, the rotation of the rotating component 134 drives the bidirectional screw 131 to rotate. The rotation of the bidirectional screw 131 drives the limiting plate 133 to move, so that the surface of the limiting plate 133 is in contact with the edge of the release paper, limiting the release paper. At the same time, the hydraulic cylinder 126 pushes the U-shaped plate 124 to descend. The descent of the U-shaped plate 124 causes the extrusion roller 125 to squeeze the release paper. The distance between the release paper and the coating roller 122 can also be adjusted. Then, the second motor 123 drives the rotating column 121 to rotate. The rotation of the rotating column 121 drives the coating roller 122 to rotate, which achieves the coating effect on the release paper. The coated release paper can be cured by the ultraviolet lamp 61.

[0027] The wiring diagrams for the ultraviolet lamp 61, the first motor 11, the hydraulic cylinder 126, the telescopic rod 127, and the control panel 15 in this utility model are common knowledge in the field. Their working principles are known technologies, and the appropriate models are selected according to actual use. Therefore, the control methods and wiring arrangements for the ultraviolet lamp 61, the first motor 11, the hydraulic cylinder 126, the telescopic rod 127, and the control panel 15 will not be explained in detail.
