[0030] Such as Figure 1 andFigure 2 As shown in the figure, an instant cooling and shaping device for the production of polyphenylene sulfide films includes an electrostatic removal mechanism. The feature is that a workbench 1 and a collection mechanism are successively arranged at the end of the electrostatic removal mechanism;
[0031] The electrostatic removal mechanism includes a body 8, and ion rods 9 are rotatably connected to both sides of the body 8; A traction mechanism 22 is arranged between the workbench 1 and the electrostatic removal mechanism. The traction mechanism 22 includes two groups of conveyor belts, and one group of conveyor belts is arranged above the other group. After the electrostatically removed film enters the traction mechanism 22, the two groups of conveyor belts jointly traction the film to move forward. The upper conveyor belt tractions the film at a certain speed and tension, and the lower conveyor belt provides stable support to ensure that the film will not wrinkle during the transmission process. A low-temperature plate 10 is arranged between the ion rods 9. The low-temperature plate 10 is fixedly connected to the body 8, and a guide roller 11 is connected to the side of the low-temperature plate 10 away from the traction mechanism 22. A pressing roller 12 is arranged on the low-temperature plate 10, and the pressing roller 12 is rotatably connected to the low-temperature plate 10 through a connecting plate 13. The ion rods 9 in the electrostatic removal mechanism start to work and release positive and negative ions. The ion rods 9 neutralize the electrostatic charges on the surface of the film, removing the static electricity on the surface of the film. At the same time, the polyphenylene sulfide film contacts the low-temperature plate 10, reducing the temperature of the film surface. The guide roller 11 on the low-temperature plate 10 can switch the surface of the film in contact with the ion rods 9, and the pressing roller 12 works together to ensure that the film can pass through the low-temperature plate 10 smoothly while removing static electricity.
[0032] As Figure 2 and Figure 3 shown in the figure, a cooling and shaping mechanism is connected to the workbench 1. The cooling and shaping mechanism includes a bracket 2, a main shaft 3 is longitudinally slidably connected to the bracket 2, a chill roll 5 is rotatably connected to the main shaft 3, and a tension spring 4 is arranged between the top of the main shaft 3 and the bracket 2. A first lead screw 6 is threadedly connected to the bracket 2, and the end of the first lead screw 6 is in contact connection with the main shaft 3. A plurality of rotating rollers 7 are evenly arranged at the lower end of the main shaft 3, and the rotating rollers 7 are rotatably connected to the bracket 2; The film enters the cooling and shaping mechanism. By rotating the first lead screw 6, the positions of the main shaft 3 and the chill roll 5 can be adjusted to adapt to films of different thicknesses. With the stable contact between the chill roll 5 and the film and the action of the internal cooling system of the chill roll 5, the surface temperature of the film rapidly drops, realizing instant cooling and inhibiting the crystallization process of the film, thereby obtaining a film with high flatness and low crystallinity.
[0033] As Figure 3 and Figure 4As shown, the collecting mechanism includes a winding roller 14, and a first driving motor 15 drives the winding roller 14 to rotate. A tensioning mechanism is arranged between the collecting mechanism and the workbench 1. The tensioning mechanism includes a fixing frame 16. A sliding frame 17 is slidably connected to the fixing frame 16. A plurality of rotating rollers 18 are symmetrically arranged above and below the sliding frame 17. The sliding frame 17 is in threaded connection with a second lead screw 19. A second driving motor 20 drives the second lead screw to rotate. The second driving motor 20 is connected to the fixing frame 16. A supporting roller 21 is connected to one side of the fixing frame 16 close to the collecting mechanism. According to production requirements, the second driving motor 20 drives the second lead screw to rotate, and then the sliding frame 17 moves up and down with the rotation of the lead screw. When the tension needs to be increased, the second driving motor 20 rotates forward to drive the sliding frame 17 to move upward, so that the rotating roller 7 contacts the film more closely; when the tension needs to be reduced, the second driving motor 20 rotates in reverse, and the sliding frame 17 moves downward, avoiding film wrinkles and ensuring that the film can smoothly enter the winding roller 14 for winding.
[0034] The working process of the present utility model is as follows:
[0035] First, the polyphenylene sulfide film enters the static electricity removing mechanism from the production line. The ion bar 9 in the static electricity removing mechanism starts to work, releasing positive and negative ions. The ions neutralize the static electricity charges on the film surface, removing the static electricity on the film surface. At the same time, the polyphenylene sulfide film contacts the low-temperature plate 10, reducing the temperature of the film surface. The guiding roller 11 on the low-temperature plate 10 can switch the surface of the film in contact with the ion bar 9. The pressing roller 12 works together to ensure that the film can smoothly pass through the low-temperature plate 10 while removing static electricity. The film after static electricity removal enters the traction mechanism 22. Two groups of conveyor belts jointly traction the film to move forward. The upper conveyor belt tractions the film at a certain speed and tension, and the lower conveyor belt provides stable support to ensure that the film does not produce wrinkles during transmission. Then the film enters the cooling and shaping mechanism. By rotating the first lead screw 6, the positions of the main shaft 3 and the chill roller 5 can be adjusted to adapt to films of different thicknesses. The stable contact between the chill roller 5 and the film, and the action of the internal cooling system of the chill roller 5, the surface temperature of the film drops rapidly, realizing instant cooling and inhibiting the crystallization process of the film, so as to obtain a film with high flatness and low crystallinity. Then the film enters the tensioning mechanism. According to production requirements, the second driving motor 20 drives the second lead screw to rotate, and then the sliding frame 17 moves up and down with the rotation of the lead screw. When the tension needs to be increased, the second driving motor 20 rotates forward to drive the sliding frame 17 to move upward, so that the rotating roller 7 contacts the film more closely; when the tension needs to be reduced, the second driving motor 20 rotates in reverse, and the sliding frame 17 moves downward, avoiding film wrinkles and ensuring that the film can smoothly enter the winding roller 14 for winding. Then the first driving motor 15 drives the rotation to wind up the film.
