[0002] The coating extrusion laminating machine, which is usually called coating machine by some manufacturers and users in the industry, is also called extrusion laminating machine, casting machine, extrusion casting machine, casting laminating machine, film coating machine, plastic coating machine, coating laminating machine (inaccurate, actually refers to hot melt adhesive scraper coating machine), and is a kind of extrusion molding machine. It has the advantages of high degree of automation, simple operation, high production speed, uniform coating thickness, high adhesion, smooth winding, environmental protection and pollution-free, saving labor and raw material costs, etc. It is an inevitable trend to replace dry laminating and hot melt adhesive coating laminating.

[0003] During the laminating process, in order to prevent bubbles from forming when applying silicone oil, the laminating extrusion compounding machine needs to press irregular holes on the surface of the laminating film. However, the hole pressing device for the laminating machine in the prior art has a relatively simple structure and has a poor effect on pressing holes on the surface of the laminating film. This causes the laminating film to easily bubble during the silicone oil application process, thereby affecting the quality of the laminating film. Utility Model Content

[0008] A further technical solution is: the driving device is a cylinder.

[0009] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0010] 1. Due to the use of the bracket, guide roller, conveying roller, pressure roller, lifting device and limit rod, when the coating film needs to be coated with silicone oil, the coating film is first passed along the surface of the two sets of conveying rollers, and the coating film after passing through passes between the guide roller and the pressure roller, and then the coating film after passing through is transported to the silicone oil coating device again. At this time, the driving ends of the driving devices in the two sets of lifting devices are extended at the same time. Since the base of the driving device is swingably connected to the support block, the connector set on the driving end of the driving device is also swingably connected to the support block. Support seat, so when the driving ends of the two drive devices are extended at the same time, the two groups of support seats can swing around the limit rod at the same time. The two groups of support seats swing around the limit rod, which can drive the clamping roller to move toward the guide roller. When the clamping roller abuts against the guide roller, the surface of the coating passing between the guide roller and the clamping roller will be close to the sandpaper wrapped around the guide roller. At this time, the sandpaper wrapped around the guide roller can effectively press holes on the surface of the coating during the transportation process, thereby making the coating more effective during the application of silicone oil.

[0015] The embodiment of the present application provides a hole pressing device for a laminating extrusion compounding machine, thereby solving the technical problem that the hole pressing device for the laminating machine in the prior art solution has a relatively simple structure and a poor effect of pressing holes on the surface of the laminating film, which causes the laminating film to easily bubble during the silicone oil coating process, thereby affecting the quality of the laminating film.

[0016] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:

[0017] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0018] A hole pressing device for a laminating extrusion laminating machine, such as Figure 1 , Figure 2 as well as Figure 3 As shown, it includes a bracket 1, a guide roller 2 with sandpaper wound around it, a conveying roller 3 for conveying the coating, a pressing roller 4 for pressing the coating, a lifting device 5 for driving the pressing roller 4 to rise and fall, and a limiting rod 6 for limiting the movement of the pressing roller 4. Two groups of conveying rollers 3 symmetrically placed up and down are arranged at the rear end of the bracket 1. The guide roller 2 is arranged at the top of the bracket 1. Two groups of lifting devices 5 symmetrically placed left and right are arranged at the front end of the bracket 1, and the two groups of lifting devices 5 are both connected to the pressing roller 4. The two groups of lifting devices 5 are connected to the limiting rod 6, and the limiting rod 6 is arranged on the bracket 1.

[0019] The lifting device 5 includes a support seat 51, a driving device 52 for driving the support seat 51 to swing, a connector 53 arranged at the driving end of the driving device 52, and a support block 54 arranged on the bracket 1. The support seat 51 is rotatably connected to the limit rod 6. The pressure roller 4 is rotatably connected to the support seat 51. The base of the driving device 52 is swingably connected to the support block 54. The connector 53 is swingably connected to the support seat 51.

[0020] The rear end of the bracket 1 is rotatably connected to two groups of conveying rollers 3 symmetrically placed up and down. The guide roller 2 is rotatably connected to the top of the bracket 1. The front end of the bracket 1 is fixedly installed with two groups of lifting devices 5 symmetrically placed left and right, and the two groups of lifting devices 5 are both transmission-connected to the clamping roller 4. The two groups of lifting devices 5 are swingably connected to the left and right ends of the limit rod 6, and the limit rod 6 is fixedly connected to the bracket 1. The driving device 52 is preferably a cylinder. The connector 53 is fixedly connected to the driving end of the driving device 52. The support block 54 is fixedly connected to the bracket 1.

[0021] Due to the arrangement of the bracket 1, the guide roller 2, the conveying roller 3, the pressing roller 4, the lifting device 5 and the limit rod 6, when it is necessary to apply silicone oil to the coating film, the coating film is firstly passed along the surface of the two groups of conveying rollers 3, and the coating film after passing through is passed between the guide roller 2 and the pressing roller 4, and then the coating film after passing through is again conveyed to the silicone oil coating device. At this time, the driving ends of the driving devices 52 in the two groups of lifting devices 5 are simultaneously extended. Since the base of the driving device 52 is swingably connected to the support block 54, the connector 53 arranged on the driving end of the driving device 52 is also swingably connected to the support block 54. The support seat 51, therefore, when the driving ends of the two groups of driving devices 52 are extended at the same time, the two groups of support seats 51 can swing around the limit rod 6 at the same time. By the two groups of support seats 51 swinging around the limit rod 6, the clamping roller 4 can be driven to move toward the guide roller 2. When the clamping roller 4 abuts against the guide roller 2, the surface of the coating passing between the guide roller 2 and the clamping roller 4 will be close to the sandpaper wound on the guide roller 2. At this time, the sandpaper wound on the guide roller 2 can effectively press holes on the surface of the coating during the transportation process, thereby making the coating more effective during the application of silicone oil.
