DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0019] Please refer to Figures 1-4 The present application provides a technical scheme: a film rewinding machine with cleaning function, comprising a fixed frame 1, the upper end of the fixed frame 1 is movably provided with a film storage roll 2 through a rotating shaft, one side of the film storage roll 2 is provided with a cleaning mechanism for cleaning the film, the cleaning mechanism comprises a stand 3, a fixed block 4, a transmission roller 5, a first movable block 6, a first adhesive roller 7, a second movable block 8 and a second adhesive roller 9, one side of the film storage roll 2 is fixedly provided with the stand 3, the surface of the stand 3 is fixedly provided with the fixed block 4 in the middle, the transmission roller 5 is movably arranged between the fixed blocks 4 through a rotating shaft, the first movable block 6 is movably arranged on the upper end of the fixed block 4, the first adhesive roller 7 is movably arranged between the first movable blocks 6 through a rotating shaft, the second movable block 8 is movably arranged on the upper end of the first movable block 6, and the second adhesive roller 9 is movably arranged between the second movable blocks 8 through a rotating shaft.

[0020] The upper end of the stand 3 is fixedly provided with a screw 10, the surface of the screw 10 is movably screwed with a nut 11 through threads, and the surface of the screw 10 is sleeved with a spring 12 between the nut 11 and the second movable block 8, the spring 12 can push the first adhesive roller 7 and the second adhesive roller 9 to adhere to each other, and can also push the first adhesive roller 7 and the film surface to adhere to each other;

[0021] The first adhesive roller 7 is an electrostatic adhesive roller, and the adhesion principle of the first adhesive roller 7 of the device is to adhere the dust on the surface of the film away through static electricity;

[0022] The surface of the second adhesion roller 9 is provided with an adhesion layer 13, the adhesion layer 13 is provided with multiple layers, and is one-to-one sleeved together, the adhesion layer 13 is a cylindrical polyethylene film sleeve provided on the outer surface of the second adhesion roller 9, the outer side of the polyethylene film is provided with an adhesion glue, and the adhesion glue material is polyacrylic adhesive (polyacrylic adhesive as glue can ensure adhesion and no delamination characteristics); the adhesion principle of the second adhesion roller 9 of the device is that the polyethylene film is made into a cylinder as a carrier, the surface is provided with the glue of the polyacrylic adhesive, and the adhesion of the polyacrylic adhesive is greater than that of the electrostatic adhesion roller. Thus, all the dust will be adhered to the surface of the adhesion layer 13 of the second adhesion roller 9; the surface of the adhesion layer 13 is provided with pre-cut holes 14, which form a pre-cut line. When this layer of adhesion layer 13 is too dirty, the pre-cut line can conveniently tear off this layer of adhesion layer 13, and then the next layer of new adhesion layer 13 can work. Thus, the replacement work of the adhesion layer 13 can be facilitated, and the diameter of the second adhesion roller 9 will become smaller with the replacement of the adhesion layer 13. At this time, through the spring 12 and the weight of the second adhesion roller 9, it can be ensured that the adhesion layer 13 on the surface of the second adhesion roller 9 can always be attached to the surface of the first adhesion roller 7. Thus, the adhesion principle of the device is electrostatic adhesion and glue adhesion. Compared with the traditional negative pressure adsorption, the contact is better, the cleaning effect is better, and new dust will not be brought by the accelerated airflow.

[0023] The surface of the adhesion layer 13 is provided with a plurality of pre-cut holes 14, which form a pre-cut line. The pre-cut line can conveniently tear off this layer of adhesion layer 13.

[0024] The surface of the screw 10 is provided with a gasket 15 below the nut 11, which can improve the stability of the spring 12 fixed by the nut 11.

[0025] Working principle: when using the device, the film in the film storage roll 2 passes between the first adhesion roller 7 and the transmission roller 5, then the film transmission also drives the first adhesion roller 7 to rotate, and the first adhesion roller 7 drives the second adhesion roller 9 to rotate at the same time. At this time, the first adhesion roller 7 uses electrostatic adsorption to adhere the dust on the surface of the film, and then the adhesion layer 13 on the surface of the second adhesion roller 9 can also adhere the dust on the surface of the first adhesion roller 7 due to its stronger adhesion, so as to prevent the dust on the surface of the first adhesion roller 7 from returning to the surface of the film. Thus, all the dust will be adhered to the surface of the adhesion layer 13 of the second adhesion roller 9. The adhesion principle of the device is electrostatic adhesion and glue adhesion. Compared with the traditional negative pressure adsorption, the contact is better, the cleaning effect is better, and new dust will not be brought by the accelerated airflow.

[0026] And the device uses the surface of the adhesion layer 13 to be provided with pre-cut holes 14, which form a pre-cut line, when the adhesion layer 13 is too dirty, the adhesion layer 13 can be easily torn through the pre-cut line, and then the next new adhesion layer 13 can work, so that the replacement work of the adhesion layer 13 can be facilitated, and with the replacement of the adhesion layer 13, the diameter of the second adhesion roller 9 becomes smaller, at this time, through the spring 12 and the weight of the second adhesion roller 9, it can be guaranteed that the adhesion layer 13 on the surface of the second adhesion roller 9 can always be attached to the surface of the first adhesion roller 7;

[0027] It should be noted that the device only draws the cleaning mechanism of one side of the adhesion film in the figure, if the other side of the film also needs to be cleaned, the film can be transmitted in S shape through the guide roller, so that the film can be automatically turned over, and then the two cleaning mechanisms can be used to clean one side of the film respectively.

[0028] It should be noted that in this paper, relationship terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between the entities or operations. Moreover, the terms "include", "contain" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or equipment.
