Problems solved by technology

[0002] At present, the packaging industry has become a sunrise industry with considerable production capacity and production level. Plastic films are widely used in the fields of textiles, food, daily necessities, pesticides and pharmaceutical packaging. The processing methods of plastic films include extrusion, blow molding, Calendering method, casting method and stretching method, the extrusion method is the most used method, which is to extrude the plastic film after heating and melting the raw materials, then cooling and forming, and then pulling and coiling to complete the finished roll film. The plastic film forming device is prone to wrinkles due to insufficient tension during the film forming and winding process, and the existing reel is not convenient to replace, and it takes a lot of time to install, disassemble and take it, which greatly reduces the film. Processing efficiency

Embodiment 1

[0032] A stable and continuous thermoplastic film-forming device for high-performance PVA-based materials, comprising an extruder 1, a cooling roller 4 is arranged below the discharge die of the extruder 1, and the two ends of the cooling roller 4 are rotatably connected to support rods 26, The first motor 3 is fixed on the pole 26, the output end of the first motor 3 is connected to one end of the cooling roller 4, the pressure roller 2 is arranged above the cooling roller 4, and the steering roller 25 is arranged on one side of the pole 26, and the steering roller One side of 25 is provided with support 5, and one side of support 5 is provided with support plate 8, and one side of support plate 8 is provided with cleaning mechanism 9, and one side of cleaning mechanism 9 is provided with reel 13, and the inside of reel 13 is provided with There are sockets 15, and both ends of the reel 13 are provided with fixing mechanisms 14;

[0033] The fixing mechanism 14 includes a mov...

Embodiment 2

[0037] As an option, see figure 2 , Figure 7 , a high-performance PVA-based material stable continuous thermoplastic film forming device, a leveling roller 20 is arranged above the reel 13, and the inner rotation of the leveling roller 20 is connected with a first crossbar 19, and the two sides of the first crossbar 19 The end is provided with a moving column 17, the outside of the moving column 17 is provided with a limiting groove 16, the upper end of the moving column 17 is connected with one end of a second spring 18, and the other end of the second spring 18 is connected to the inner top of the limiting groove 16, and the limiting groove 16 is set inside the support base 10 , and a second notch 27 is provided on a side of the limiting groove 16 close to the first crossbar 19 , and the first crossbar 19 passes through the second notch 27 .

[0038] Specifically, the processed plastic film is rewound. At this time, the leveling roller 20 is close to the upper end of the ...

Embodiment 3

[0040] As an option, see figure 1 , a high-performance PVA-based material stable continuous thermoplastic film forming device, the support plate 8 is provided with a fixed roller 23, the upper end of the roller surface of the fixed roller 23 is provided with a pressure sensor, and the lower end of the support plate 8 is provided with a second cylinder 22, Both sides of the support plate 8 are provided with equal height tension rollers 21 , the input signal end of the pressure sensor is connected to the controller, and the signal output end of the controller is connected to the second air cylinder 22 .

[0041] Specifically, when the plastic film passes through the pressure sensor arranged on the roller surface of the fixed roller 23, the pressure sensor detects the pressure. When the pressure is too large, the second cylinder 22 drives the support plate 8 and the fixed roller 23 to descend. , so that the tension of the plastic film becomes smaller, preventing the plastic film ...
