DETAILED DESCRIPTION
[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0023] like Figure 1-Figure 2 As shown, a double-head film blowing machine includes a fixed bracket 1, which is fixed above the film blowing machine body 2, and the raw material is put into the inner tank 7 from the feed port 5, and the raw material inside the inner tank 7 is heated by the provided heating tube 8. At the same time, the heating temperature is monitored by the provided thermometer 6 to prevent overheating. When the raw material is heated to a suitable temperature, the first motor 4 is started, and the spiral blade 9 is driven by the provided first motor 4 to rotate, so as to extrude the raw material and transport it to the inside of the film blowing machine body 2.
[0024] like Figure 3As shown, a double-head film blowing machine connects the gas collecting tank 23 to the external air compressor, and at the same time connects the air pipe 25 to the gas collecting tank 23 and the film blowing machine body 2, and opens the control valve 26. When the film blowing machine body 2 is working, the gas collecting tank 23 stores the compressed air, and the air pressure inside the gas collecting tank 23 is monitored by the set pressure gauge 24, and the gas is transported to the film blowing machine body 2 through the set air pipe 25. The set control valve 26 is convenient for the staff to adjust the gas pressure and flow rate to prevent the air pressure from being too high and affecting the film blowing effect.
[0025] like Figure 4 As shown, a double-head film blowing machine passes the film through the middle of a pedestrian board 10 and passes around the middle of a roller 11 in turn. The film is initially extruded by the pedestrian board 10, and deeply extruded by the roller 11. The roller 11 is convenient for workers to adjust the tension of the film. The fan 13 is used to dissipate the heat of the film to prevent the heat inside the film from not being dissipated in time during the winding process. After winding, the heat accumulates and affects the quality of the film. The filter 14 is used to filter impurities in the air to prevent dust in the air from adhering to the surface of the film.
[0026] like Figure 5 As shown, a double-head film blowing machine passes the film through the middle of the extrusion rod 15, and the upper and lower surfaces of the film are squeezed by the extrusion rod 15 to discharge the air inside the film. The cylinder 16 is provided to facilitate the staff to adjust the distance between the extrusion rods 15 to prevent the film from being damaged during winding due to excessive squeezing. The winding drum is placed in the middle of the fixed block 20, and the transmission rod 21 is driven to rotate by the second motor 18, so as to control the two groups of support plates 19 to move relative to each other, clamp the winding drum, fix one end of the film on the outside of the winding drum, and drive the fixed block 20 to rotate by the third motor 22, so as to drive the winding drum to rotate and wind the film. At the same time, it is convenient for the staff to load and unload materials, which greatly reduces the labor intensity of the staff, facilitates the operation of the workers, improves the practicability of the equipment, reduces the investment cost, and improves the market competition advantage.
