Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0026] Embodiment 1

[0027] Please refer to Figure 1 And Figure 2, the utility model relates to a plastic extrusion flat film and flat wire unit, which includes a film pressing component 1 and a thermoplastic component 2. The film pressing component 1 includes a base table 101, a thermoplastic cylinder 102 and a flat film die head 103. The thermoplastic component 2 includes a cooling roller 201, a fixed roller seat 202 and a movable roller seat 203. By arranging the cooling roller 201 in front of the discharging end of the flat film die head 103 and arranging the fixed roller seat 202 and the movable roller seat 203 on one side of the cooling roller 201, the pulled flat film is quickly cooled by the cooling roller 201, then bypasses the transfer rollers on the fixed roller seat 202 and the movable roller seat 203, and the flat film between the movable roller seat 203 and the fixed roller seat 202 is heated, so that the flat film is thinned; by sliding and adjusting the movable roller seat 203, the distance between the movable roller seat 203 and the fixed roller seat 202 is increased, the tension on the flat film wound between the fixed roller seat 202 and the movable roller seat 203 is increased, and the thickness of the heated flat film is pulled thinner.

[0028] Specifically, the thermoplastic cylinder 102 is arranged at one end of the upper end of the base table 101, the flat film die head 103 is arranged on the base table 101 and communicated with the discharging end of the thermoplastic cylinder 102. The cooling roller 201 is rotatably installed on both sides of the base table 101, the cooling roller 201 is in front of the outlet end of the flat film die head 103, the fixed roller seat 202 is fixedly arranged on the side of the cooling roller 201 far from the flat film die head 103, the movable roller seat 203 is horizontally slidably sleeved on the table top of the base table 101, the movable roller seat 203 is arranged on the side of the fixed roller seat 202 far from the cooling roller 201, and two turning rollers are respectively rotatably installed between the fixed roller seat 202 and the movable roller seat 203.

[0029] Furthermore, both the fixed roller seat 202 and the movable roller seat 203 are of U-shaped plate structures. The opening of the U-shaped plate of the fixed roller seat 202 faces the cooling roller 201, and the opening of the U-shaped plate of the movable roller seat 203 faces away from the cooling roller 201. A turning roller is respectively rotatably installed at the upper ends between the vertical plates on both sides of the fixed roller seat 202 and the movable roller seat 203. The lower sides of the vertical plates on both sides of the fixed roller seat 202 and the movable roller seat 203 extend and are fixedly provided with transfer roller ears. A transfer roller is respectively rotatably installed between the transfer roller ears at the lower ends of the fixed roller seat 202 and the movable roller seat 203. The plastic flat film cooled by the cooling roller 201 successively bypasses the transfer roller between the transfer roller ears at the lower end of the fixed roller seat 202, the transfer roller at the upper end of the fixed roller seat 202, the transfer roller at the upper end of the movable roller seat 203 and the transfer roller between the transfer roller ears at the lower end of the movable roller seat 203.

[0030] Furthermore, two guide post ears 101a are respectively fixedly provided on both side surfaces of the base table 101. A horizontal guide post 101a-1 is respectively fixedly provided between the two guide post ears 101a on each side.

[0031] The operation process of this embodiment is as follows:

[0032] The plastic flat film pulled out from the flat film die head 103 is wound around the cooling roller 201 for cooling, and then successively passes around the transfer rollers between the transfer roller ears at the lower end of the fixed roller seat 202, the transfer roller at the upper end of the fixed roller seat 202, the transfer roller at the upper end of the moving roller seat 203, and the transfer roller between the transfer roller ears at the lower end of the moving roller seat 203. The plastic flat film between the fixed roller seat 202 and the moving roller seat 203 is heated. The moving roller seat 203 is slid to adjust the tension on the plastic flat film between the fixed roller seat 202 and the moving roller seat 203, so that the heated plastic flat film is thinned.

[0033] Embodiment 2

[0034] Please refer to Figures 1 to 5 , on the basis of Embodiment 1, a cross plate 101c is provided above the chassis 101, and a hot air assembly 204 is provided at the upper end of the cross plate 101c. The plastic flat film below is heated by the hot air assembly 204, so as to facilitate thinning of the plastic flat film.

A cross plate 101c is provided at the upper ends of the cooling roller 201 and the moving roller seat baffle 101b on the chassis 101, and a hot air assembly 204 is provided at the upper end of the cross plate 101c.

[0036] Furthermore, the hot air assembly 204 includes a hot air chamber 204a, an electric heating frame 204b, and a group of fans 204c. A ventilation window 101c-1 is penetrated and opened on the plate surface of the cross plate 101c between the fixed roller seat 202 and the moving roller seat baffle 101b. The lower opening of the hot air chamber 204a is communicated with the ventilation window 101c-1. The electric heating frame 204b is arranged in the hot air chamber 204a, and the fans 204c are arranged at the upper opening of the hot air chamber 204a. The fans 204c suck air into the hot air chamber 204a, and the air is heated by the electric heating frame 204b. Finally, the heated air blows onto the plastic flat film below through the ventilation window 101c-1 to heat the plastic flat film.

[0037] Furthermore, windshields 203b are fixedly provided at the upper ends of the two side plates of the moving roller seat 203, and the windshields 203b extend towards the side of the moving roller seat baffle 101b.

[0038] Furthermore, a windshield groove 101b-1 is penetrated and opened at the upper end of the plate surface of the moving roller seat baffle 101b, and the windshields 203b are slidably sleeved in the windshield groove 101b-1 to prevent the hot air from heating the plastic flat film below the windshields 203b and prevent the plastic flat film wound around the moving roller seat 203 from being overheated and softened.

[0039] The operation process of this embodiment is as follows:

[0040] The fan 204c sucks air into the hot air chamber 204a, and the electric heating frame 204b heats the air. Finally, the heated air blows downward onto the plastic flat film through the ventilation window 101c-1 to heat the plastic flat film. Slide and adjust the moving roller seat 203 to increase the pulling force on the plastic flat film, so that the plastic flat film is pulled thinner. At the same time, the wind deflector 203b is slidably sleeved in the wind deflector groove 101b-1 to block the hot air blown from above, preventing the plastic flat film wound around the moving roller seat 203 from being overheated and softened.
