Description

Technical Field

[0001] This utility model relates to a PVC plastic film processing equipment, and more specifically, to a PVC plastic film static electricity removal device. Background Technology

[0002] A PVC plastic film static eliminator is a device specifically designed to remove static electricity from the surface of PVC plastic film. Its main function is to eliminate or reduce the static charge on the surface of the PVC plastic film through specific technical means, such as spraying antistatic liquid or other physical methods, thereby preventing various problems caused by static electricity, such as dust adhesion, film sticking, and equipment malfunction.

[0003] Existing PVC plastic film antistatic devices directly spray antistatic liquid onto the surface of the PVC plastic film during use. However, due to the high viscosity of the antistatic liquid, it is difficult for it to penetrate into the plastic film. Furthermore, the high viscosity of the antistatic liquid makes it difficult to spread evenly on the film surface, resulting in uneven distribution and reduced antistatic effect.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide an antistatic device for PVC plastic film. A pressure roller squeezes the antistatic liquid on the surface of the plastic film, allowing the liquid to penetrate the film's micropores more effectively and bond more tightly with the film material. By vertically positioning the plastic film on one side of a standing plate, the accumulation of the antistatic liquid on the film surface is prevented, allowing for better flow and diffusion, thus improving the antistatic effect. Simultaneously, the pressure roller effectively flattens the antistatic liquid sprayed on the film surface, eliminating droplets, streaks, or accumulation caused by uneven spraying. This results in a uniform and continuous coating of antistatic liquid on the film surface, enhancing the antistatic effect.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a PVC plastic film antistatic device includes a workbench, a vertical plate is fixedly installed on the upper left side of the workbench, a feeding roller is movably connected to the upper end of the vertical plate, a sliding groove is opened on the rear right side of the vertical plate, a driving mechanism is arranged in the sliding groove, a sliding frame is threadedly connected to the outer surface of the driving mechanism, a cylinder is fixedly installed on the right end of the sliding frame, a movable frame is fixedly installed at the output end of the cylinder, a pressure roller is movably connected to the left end of the movable frame, a connecting pipe is fixedly inserted and connected to the upper end of the movable frame, a liquid storage tank is fixedly installed at the upper end of the connecting pipe, an inlet pipe is fixedly installed at the upper end of the liquid storage tank, a through pipe is fixedly installed at the lower end of the connecting pipe, and a plurality of spray pipes are fixedly installed on the outer surface of the through pipe, the spray pipes being located above the pressure roller.

[0007] The present invention is further configured such that: the driving mechanism includes a lead screw, a servo motor is fixedly installed at the upper end of the lead screw, the lead screw is movably disposed in a slide groove, the servo motor is fixedly connected to the upper end of the upright plate, and the sliding frame is threadedly connected to the outer surface of the lead screw.

[0008] The present invention is further configured such that: a spiral groove is provided at the upper end of the workbench, and a storage box is provided below the spiral groove.

[0009] The present invention is further configured such that four support legs are fixedly installed at the lower end of the workbench.

[0010] The present invention is further configured such that the movable frame is L-shaped.

[0011] In summary, this utility model has the following beneficial effects:

[0012] 1. The pressure roller can squeeze the antistatic liquid on the surface of the plastic film. The rolling action of the pressure roller allows the antistatic liquid to penetrate better into the tiny pores of the film and bond more tightly with the film material. By vertically setting the plastic film on one side of the upright plate, the accumulation of antistatic liquid sprayed on the surface of the plastic film is prevented, and the antistatic liquid can flow and diffuse better, improving the antistatic effect of the antistatic liquid on the film. At the same time, the pressure roller can effectively flatten the antistatic liquid sprayed on the film surface through its rolling and the pressure it applies. This flattening action helps to eliminate droplets, streaks or accumulation caused by uneven spraying, so that the antistatic liquid forms a uniform and continuous coating on the film surface, improving the antistatic effect on the film.

[0020] A PVC plastic film antistatic device, such as Figures 1 to 2As shown, the device includes a workbench 1. A vertical plate 2 is fixedly installed on the upper left side of the workbench 1. A feeding roller 3 is movably connected to the upper end of the vertical plate 2. A sliding groove 4 is opened on the rear right side of the vertical plate 2. A drive mechanism 5 is installed in the sliding groove 4. A sliding frame 6 is threadedly connected to the outer surface of the drive mechanism 5. A cylinder 7 is fixedly installed on the right end of the sliding frame 6. A movable frame 8 is fixedly installed at the output end of the cylinder 7. The movable frame 8 is L-shaped. A pressure roller 9 is movably connected to the left end of the movable frame 8. A connecting pipe 10 is fixedly inserted and connected to the upper end of the movable frame 8. A liquid storage tank 11 is fixedly installed at the upper end of the connecting pipe 10. An inlet pipe 12 is fixedly installed at the upper end of the liquid storage tank 11. A through pipe 13 is fixedly installed at the lower end of the connecting pipe 10. Several spray pipes 14 are fixedly installed on the outer surface of the through pipe 13. The spray pipes 14 are located above the pressure roller 9.

[0021] like Figure 2 As shown, the drive mechanism 5 includes a lead screw 51, a servo motor 52 is fixedly installed at the upper end of the lead screw 51, the lead screw 51 is movably disposed in the slide groove 4, the servo motor 52 is fixedly connected to the upper end of the vertical plate 2, and the sliding frame 6 is threadedly connected to the outer surface of the lead screw 51.

[0022] like Figure 1 As shown, a spiral groove 15 is provided at the upper end of the workbench 1, and a storage box 16 is provided below the spiral groove 15. The storage box 16 is used to collect the plastic film after processing. The plastic film falls through the spiral groove 15 and is collected in the storage box 16 below.

[0023] Four support legs 17 are fixedly installed at the lower end of the workbench 1, which provide support and stability to the workbench 1.

[0024] Working Principle: The feeding roller 3 is driven to rotate clockwise by the motor on the front side of the feeding roller 3, thereby feeding the plastic film on the feeding roller 3 and vertically setting it on the right side of the upright plate 2. By activating the cylinder 7, a commonly used pneumatic actuator that converts gas pressure energy into mechanical energy, the load is propelled to move linearly. When the cylinder 7 pushes the pressure roller 9 to the left, it contacts the surface of the plastic film, opening the valve on the right side of the connecting pipe 10. This allows the antistatic liquid in the storage tank 11 to enter several spray nozzles 14 through the connecting pipe 10 and the through pipe 13. Then, the antistatic liquid in the spray nozzles 14 is sprayed onto the surface of the plastic film due to gravity. The pressure roller 9 is driven to rotate by the motor on the front side of the pressure roller 9, which squeezes the antistatic liquid on the surface of the plastic film. The rolling action of the pressure roller 9 allows the antistatic liquid to better penetrate into the tiny pores of the film, bonding more tightly with the film material. By vertically setting the plastic film on one side of the upright plate 2, the antistatic liquid is successfully distributed. To prevent the accumulation of antistatic liquid sprayed on the surface of the plastic film, the antistatic liquid can flow and diffuse better, improving the antistatic effect of the antistatic liquid on the film. At the same time, the pressure roller 9 can effectively flatten the antistatic liquid sprayed on the film surface through its rolling and applied pressure. This flattening action helps to eliminate droplets, streaks or accumulation caused by uneven spraying, so that the antistatic liquid forms a uniform and continuous coating on the film surface, improving the antistatic effect on the film. The pressure roller 9 is made of rubber, which has good wear resistance and excellent elasticity to ensure that it will not damage the film surface during rolling. The servo motor 52 drives the lead screw 51 to rotate. The servo motor 52 is a device that can convert electrical energy into mechanical energy. Its working principle is based on existing technology. When the sliding frame 6 moves up and down along the lead screw 51, it can drive the spray nozzle 14 and the pressure roller 9 to move up and down, so as to spray the antistatic liquid on the plastic film more comprehensively and roll it evenly.
