DETAILED DESCRIPTION

[0024] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0025] The present technical solution provides a perforation mechanism of a film laminating machine, comprising a machine base 1, a first cooling roller 2, a needling device 3, and a second cooling roller 4, wherein the first cooling roller 2, the needling device 3, and the second cooling roller 4 are mounted on the top of the machine base 1 along the conveying direction of the film 5; the first cooling roller 2 and the second cooling roller 4 are both rotatable relative to the machine base 1, and the needling device 3 is used to perforate the film 5;

[0026] The needling device 3 includes a support base 31, a conveying rubber roller 32, and a needling roller 33, and the roller surface of the needling roller 33 is evenly and protrudingly provided with a plurality of needles; the support base 31 is mounted on the top of the machine base 1, and the needling roller 33 and the conveying rubber roller 32 are rotatably mounted inside the support base 31, with the needling roller 33 being located directly above the conveying rubber roller 32; the needling roller 33 can move up and down relative to the support base 31, and the up and down movement of the needling roller 33 is used to contact and move away from the roller surface of the conveying rubber roller 32;

[0027] The film 5 is sequentially attached to the roller surfaces of the first cooling roller 2, the conveying rubber roller 32 and the needling roller 33, and is transported along the unloading direction of the cooling mechanism by the rotation of the first cooling roller 2, the conveying rubber roller 32 and the needling roller 33.

[0028] In the production and processing of a simulated wall cloth finishing material, due to the airtightness of the film material, the glue is difficult to dry after the wall cloth film is glued to the wall. Over time, problems such as mold, bubbling and degumming will occur, seriously affecting the service life and aesthetics of the wall film.

[0029] Therefore, in order to solve the above technical problems, this technical solution proposes a punching mechanism for a film laminating machine, such as Figure 1-2 As shown, a needle roller for puncturing the film is added to the cooling mechanism. Since the film is densely covered with air holes, the wall cloth film with small holes can be glued to the wallboard after heating, which speeds up the drying of the glue and solves the problems of mold, blistering and degumming caused by the glue not drying for a long time.

[0030] Specifically, the cooling mechanism of this embodiment includes a base 1, a first cooling roller 2, a needling device 3, and a second cooling roller 4. The film 5 is sequentially conveyed along the unloading direction of the cooling mechanism, passing through the first cooling roller 2, the needling device 3, and the second cooling roller 4. The first cooling roller 2 and the second cooling roller 4 are conventional cooling rollers used in film lamination processing equipment, and their structures are not described in detail here. The number of first cooling rollers 2 and second cooling rollers 4 is not limited and can be set according to actual production conditions.

[0031] Furthermore, the needling device 3 of the present invention is used to puncture holes in the film 5, and specifically includes a support seat 31, a conveying rubber roller 32, and a needling roller 33 that can move up and down. When it is necessary to puncture holes in the film 5, first, the film 5 is made to fit on the top of the conveying rubber roller 32, and then the needling roller 33 is moved downward, and the roller surface of the needling roller 33 is made to fit with the roller surface of the conveying rubber roller 32. Then, during the conveying process of the film 5, holes can be punctured in the film 5 by the needling device 3. Since the material of the conveying rubber roller 32 of the present invention is colloid, including but not limited to colloid materials such as rubber and silicone, even if the needles of the needling roller 33 pierce the conveying rubber roller 32, they can be easily pulled out without affecting the conveying function of the conveying rubber roller 32. When the cooling mechanism needs to be replaced, the needling roller 33 can be moved upward to facilitate the removal of the film 5 from the cooling mechanism.

[0032] It should be noted that, in this solution, a pressure regulating valve (not shown in the figure) can be provided in the cooling mechanism to adjust the contact pressure between the needling roller 33 and the conveying rubber roller 32 through the pressure regulating valve, thereby improving the controllability of the needling device 3; further, a pressure gauge (not shown in the figure) can be provided between the needling roller 33 and the conveying rubber roller 32 to display the size of the contact pressure between the needling roller 33 and the conveying rubber roller 32.

The two side ends of the needling roller 33 are connected to the slide rail 34, and the needling roller 33 can move up and down along the extension direction of the slide rail 34.

[0034] In one embodiment of the present technical solution, vertically extending slide rails 34 are provided on both sides of the interior of the support seat 31. The slide rail 34 located on one side of the support seat 31 is connected to one end of the needling roller 33, and the slide rail 34 located on the other side of the support seat 31 is connected to the other end of the needling roller 33, so that the needling roller 33 can move up and down along the extension direction of the slide rail 34, which is beneficial to improving the movement stability of the needling roller 33 and facilitating its contact and separation with the conveying rubber roller 32.

[0035] To further illustrate, the acupuncture device 3 further includes a sliding driver 35 , which is installed on both sides of the top of the support base 31 , and the output end of the sliding driver 35 is connected to the end of the acupuncture roller 33 .

[0036] In another embodiment of the present technical solution, the up and down movement of the needling roller 33 is driven by a sliding driver 35, and the sliding driver 35 is installed on both sides of the top of the support seat 31, which is conducive to ensuring that the roller surface of the needling roller 33 is horizontal and achieving its stable movement.

[0037] It should be noted that the sliding actuator 35 of this solution can be a cylinder, which is not limited here. At the same time, in one embodiment, this solution can control the extension and contraction of the cylinder output end through a reversing solenoid valve (not shown in the figure), thereby controlling the up and down movement of the needling roller 33.

[0038] To further illustrate, the conveying rubber roller 32 is located above the first cooling roller 2 and the second cooling roller 4 , and the needling device 3 is detachably mounted on the top of the machine base 1 .

[0039] In a preferred embodiment of the present technical solution, the acupuncture device 3 is installed in a detachable manner, so that the acupuncture device 3 of this solution can be installed on the original cooling mechanism in any film laminating machine without the need to modify the original cooling mechanism, which is more conducive to the on-demand use of the acupuncture device 3.
