[0038] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0039] like Figure 1 As shown, a specific implementation of the film production line provided in this embodiment includes: a coating device 1, a heating and stretching device 2, a traction device and a winding device 8 arranged in sequence; the coating device 1 has a coating head 27 for spraying the slurry onto the forming surface to form a film; the heating and stretching device 2 has a peeling roller 9 for peeling the film off the forming surface, and the heating and stretching device 2 also has a plurality of heating rollers 10 arranged in sequence, through which the plurality of heating rollers 10 are used to heat and stretch the film; the traction device is used to pull the film; the winding device 8 is used to wind the film onto the winding roller 24. Specifically, in this embodiment, the forming surface can be the outer surface of a roller with a larger diameter, and the roller is driven to rotate by a rotary drive device.
[0040] The film production line provided in this embodiment is used to heat and stretch the film through the setting of a heating and stretching device 2, so that the thickness of the film meets the requirements, and the tension of the film is controlled by a number of heating rollers 10 arranged in sequence, and then the film is pulled by a traction device to maintain control of the tension of the film, thereby avoiding problems such as tearing and wrinkling of the film.
[0041] like Figure 2As shown, in the film production line provided by this embodiment, in the heating and stretching device 2, several heating rollers 10 are arranged in a staggered manner, and each heating roller 10 controls the rotation speed independently. Along the conveying direction of the film, the rotation speed of the heating roller 10 gradually increases. Specifically, in this embodiment, several heating rollers 10 are arranged in a staggered manner up and down, and the film is arranged in an S-shaped manner on several heating rollers 10. Each heating roller 10 is connected to the motor through a reducer, so that the rotation speed of each heating roller 10 can be controlled independently. Through the above arrangement, the rotation speed of several heating rollers 10 is increased, which can stretch the film and stretch the thickness of the film to the required thickness. Of course, the above description is not restrictive. In some alternative embodiments, several heating rollers 10 may not be arranged in a staggered manner up and down, for example, they may be arranged in a staggered manner left and right. Each heating roller 10 may also not be connected to the motor through a reducer, for example, it may be directly connected to the motor.
[0042] like Figure 3 As shown, in this embodiment, the traction device has a light box 11 for the film to pass through. In this way, the staff can test the film at the light box 11 to determine whether the thickness and quality of the film are qualified. Of course, the above description is not restrictive, and in some alternative embodiments, the light box 11 can be omitted.
[0043] like Figure 3 As shown, in this embodiment, the traction device includes: a tensioning roller 12 and a guide roller 13. The tensioning roller 12 is connected to a driving device, and the tensioning roller 12 is driven by the driving device to move the tensioning roller 12 to tension the film. There are a plurality of guide rollers 13. Through the cooperation between the guide rollers 13 and the tensioning roller 12, the film is always attached to the tensioning roller 12, so as to tension the film. Specifically, the driving device can be a cylinder, and the tensioning roller 12 can be set on a slide, so that the tensioning roller 12 is driven by the driving device to move on the slide.
[0044] like Figure 1 As shown, the film production line provided in this embodiment further includes: a deviation correcting device 5, which is arranged before the winding device 8, and is used to adjust the position of the film to the center.

Specifically, the deflection correction frame 15 rotates horizontally on the frame 14, and the film is supported above the deflection correction roller 16. When the deflection correction frame 15 rotates horizontally on the frame 14, the position of the film can be driven to be adjusted to the center.

When the deflection correction frame 15 rotates on the frame 14, the moving trajectory of the sliding assembly supported at the position of the deflection correction frame 15 is arc-shaped. Through the above arrangement, this embodiment can support the deflection correction frame 15 more smoothly and stably when the deflection correction frame 15 rotates. Of course, the above description is not restrictive. In some alternative embodiments, the sliding assembly 18 can also adopt other structures, for example, an arc-shaped slide rail can be used in conjunction with a slider, etc.
[0048] like Figure 1 As shown, the film production line provided in this embodiment further includes: a storage rack 6, which is arranged before the traction device, and the storage rack 6 has support rollers 21 that can move closer to and farther away from each other. When the storage rack 6 is in use, the film is arranged on the support rollers 21, and the support rollers 21 move closer to each other to release the film, and the support rollers 21 move farther away from each other to collect the film, so that when the winding roller 24 is replaced, the film is stored and released by the storage rack 6. Of course, the above description is not restrictive, and in some alternative embodiments, the storage rack 6 can be omitted.
[0049] like Figure 8As shown, in the storage rack 6, a plurality of support rollers 21 are arranged in an alternating manner up and down, wherein the support roller 21 located at the top is arranged on a sliding frame 22, and the sliding frame 22 is arranged on a vertical slide module 23, so that the sliding frame 22 can slide up and down, thereby changing the distance between the upper support roller 21 and the lower support roller 21.

Specifically, the traction device includes: an unwinding traction device 3 and a winding traction device 7. The unwinding traction device 3 is arranged before the drying device 4, and is used to pull the film before the drying device 4; the winding traction device 7 is arranged after the drying device 4, and is used to pull the film after the drying device 4. Through the above arrangement, it is ensured that the film always keeps its tension under control in the drying device 4, and the quality of the film is ensured. Of course, the above description is not restrictive. In some alternative embodiments, only one traction device may be provided.
[0053] like Fig.10As shown, in the film production line provided in this embodiment, the winding device 8 includes: a winding roller 24 and a swing kiss roller 25 that can move in a direction away from the winding roller 24. As the diameter of the film on the winding roller 24 gradually increases, the swing kiss roller 25 gradually moves away from the winding roller 24, and during the movement of the swing kiss roller 25, the swing kiss roller 25 is always in contact with the winding roller 24. Through this arrangement, the tension of the film wound onto the winding roller 24 can be guaranteed, and problems such as tearing and wrinkling of the film can be avoided. Specifically, the swing kiss roller 25 can be set on a linear slide module 26, and the linear slide module 26 can be used to approach or move away from the winding roller 24. Of course, the above description is not restrictive. In some alternative embodiments, the swing kiss roller 25 can be omitted, or set on other structures, such as being abutted against the winding roller 24 by the elastic force of an elastic member.

The vertical adjustment mechanism 29 can adopt the cooperation of a vertical screw and a slider, and the vertical screw is driven to rotate by a motor, thereby driving the slider that cooperates with the vertical screw to move in the vertical direction. The bracket and the coating head 27 form a gantry structure, and the rotation adjustment mechanism 30 is symmetrically arranged at both ends of the coating head 27. The rotation adjustment mechanism 30 has a rotating platform that rotates along a vertical plane, and the coating head 27 is driven by the rotating platform to adjust the angle.
