[0012] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0013] Specific implementation method: Combination Figure 1-3As shown, the production device of modified polymer film includes a machine 1, one side of the machine 1 is rotatably connected to a film-forming ring 5 that is transmission-connected to a driving device, the outer circumferential surface of the film-forming ring 5 has a high degree of smoothness, and the film is easy to separate from it, the machine 1 is provided with a support 12, the support 12 is provided with a storage tank 2, the storage tank 2 is used to contain an N, N-dimethylformamide solution in which a polyvinylidene fluoride-based grafted modified polymer is dissolved, a liquid outlet pipe 21 is provided at the bottom of the storage tank 2, the support 12 is provided with a through hole through which the liquid outlet pipe 21 can pass, the liquid outlet pipe 21 is provided with a valve 22 and a brush head 23 is provided at its lower end, and a soft porous material is provided at the lower end of the brush head 23 The coating brush head 23 is located at the top of the film forming circle 5 and contacts with its outer circumference. The outside of the film forming circle 5 is provided with a heating sleeve 4 fixed on the machine table 1. The machine table 1 is also provided with a winding base 11. The winding base 11 is provided with a rectangular through groove 111 extending in the direction through the axis of the film forming circle 5. A sliding seat 3 is slidably connected in the through groove 111. A winding shaft 31 is rotatably connected to one side of the sliding seat 3. The winding shaft 31 is higher than the position of the axis of the film forming circle 5. The sliding seat 3 has a certain weight, so that the winding shaft 31 wrapped with a thin film can be pressed against the outer circumference of the film forming circle 5 by its own weight, so that the winding shaft 31 can rotate under the drive of the film forming circle 5. When in use, the coating head 23 applies the N,N-dimethylformamide solution containing the grafted modified polymer of polyvinylidene fluoride to the top of the film-forming circle 5. The film-forming circle 5 rotates clockwise, and the coating layer is dried by the heating sleeve 4 at 50-100°C and then comes to the winding shaft 31 rotating counterclockwise and is wound on the winding shaft 31 (at the beginning, the front part of the film needs to be manually wound on the winding shaft 31 for a while, and then it can be wound automatically). Since the winding shaft 31 with the film wound is driven to rotate by the film-forming circle 5, the outermost film of the winding shaft 31 has the same linear speed as the film on the film-forming circle 5, that is, the feeding speed of the film is the same as the winding speed. When the film layer on the winding shaft 31 becomes thicker and thicker, the sliding seat 3 will retreat upward along the through groove 111. The length of the film produced in this way can be very large, and there is no need to stop to replace the glass sheet, so the efficiency is high.

[0014] The driving device is a motor 6 fixed on the machine 1. A gear ring 51 is provided on the side of the film forming circle 5 close to the machine 1. A gear 61 meshing with the gear ring 51 is provided on the rotating shaft of the motor 6. The rotation of the motor 6 can drive the film forming circle 5 to rotate.

[0015] The heating sleeve 4 extends in an arc shape, has a hollow interior and is provided with water pipes at both ends. When in use, the two water pipes are connected to a hot water supply device through a pipeline. Hot water provided by the hot water supply device flows into the heating sleeve 4 from one water pipe and then flows out from the other water pipe, thereby heating the heating sleeve 4.

Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention.
