Description

Technical Field

[0001] This utility model relates to the field of release film production, and in particular to an electrostatic elimination device for release film production. Background Technology

[0002] Release film is a commonly used material in heat transfer printing. After anti-static and scratch-resistant treatment, the product has excellent adsorption and adhesion. Release film is now widely used in packaging, printing, screen printing, pad printing, nameplates, membrane switches, flexible circuits, insulating products, circuit boards, laser anti-counterfeiting, lamination, electronics, sealing materials, reflective materials, adhesive products, die-cutting and punching processing and other industries. Static electricity generated during the production process will reduce the service life of the release film and affect its production quality, so it is necessary to eliminate static electricity.

[0003] Chinese Patent No. CN213043882U discloses a release film electrostatic elimination device, including an electrostatic eliminator, a humidifier, an air outlet, and a fan. The two side shafts of the electrostatic eliminator are rotatably connected to the two side walls of the main frame through bearings, and the right end shaft of the electrostatic eliminator is connected to the output end of the drive unit through bevel gear meshing. The right side of the humidifier is connected to a prior art steam generator. When the fan and humidifier are started, water is conducted to the electrostatic eliminator in the form of steam, and the humidifier is in a continuous rotating state. The cooperation between the humidifier and the baffle can achieve intermittent humidification of the electrostatic eliminator, thus achieving continuous humidification. The electrostatic eliminator is wrapped with a sponge layer. The electrostatic eliminator rotates under the drive of an external motor, and the release film contacts the surface of the electrostatic eliminator, and electrostatic separation is achieved through the moist sponge layer.

[0004] However, the aforementioned patent requires connecting the humidifying cylinder to an external steam generator for static elimination of the release film, which is cumbersome during connection and installation. Furthermore, the sponge layer wrapped in the humidifying cylinder is prone to insufficient moisture when separating static electricity from the release film, which can affect the static elimination effect and make it difficult to continuously moisten the release film, thus reducing the static elimination effect. Therefore, we propose a static elimination device for release film production to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 In this utility model, an electrostatic elimination device for release film production includes a support platform 1, a winding mechanism 2 above the support platform 1, a support cover 3 fixedly installed on the outer surface of the support platform 1, a first variable frequency motor 9 fixedly installed on the outer surface of the support cover 3, an electrostatic elimination cotton roller 8 fixedly installed at the output end of the first variable frequency motor 9, a liquid storage tank 10 fixedly installed on the upper surface of the support cover 3, and a quantitative control valve 12 fixedly connected to the bottom surface of the liquid storage tank 10. The quantitative control valve 12 mainly consists of a valve body, a valve core, a drive mechanism, and a flow regulating component. The drive mechanism can be electric or manual. If it is electric, it is equipped with a micro motor, the output shaft of which is connected to the valve core. The controller 15 sends an electrical signal to control the rotation angle and speed of the motor, thereby precisely adjusting the position of the valve core. If it is manually driven, it is equipped with an adjustment knob, which the operator can rotate to adjust the valve core position. The valve core moves, and a flow guide shroud 13 is fixedly embedded on the upper surface of the support cover 3. The bottom end of the quantitative control valve 12 passes through the flow guide shroud 13 and extends into the interior of the flow guide shroud 13. An elimination shroud 4 is fixedly installed on the upper surface of the support platform 1. An ion air bar 7 is fixedly installed on the inner wall of the elimination shroud 4. The ion air bar 7 is mainly composed of an ionization needle and a high-voltage power supply. Its principle of eliminating static electricity is based on ionization and charge neutralization. Two fan assemblies 5 are provided on the upper surface of the elimination shroud 4. A controller 15 is fixedly installed on the outer surface of the support cover 3. The ion air bar 7 installed on the elimination shroud 4 can generate ion air, which can neutralize the static electricity on the release film surface. Through the wetting assembly composed of the liquid storage tank 10, the quantitative control valve 12, the flow guide shroud 13 and the flow guide cotton plate 14, the liquid flow can be precisely controlled by the quantitative control valve 12, and the liquid can be evenly dispersed on the flow guide cotton plate 14, which can continuously wet the static electricity elimination cotton roller 8.

[0024] In a further embodiment, both fan assemblies 5 include fan covers 501 fixedly embedded on the upper surface of the elimination hood 4. Silent fans 502 are fixedly installed on the inner walls of both fan covers 501, and both silent fans 502 are located above the ion air bar 7. Protective mesh plates 503 are threadedly connected to the inner walls of both fan covers 501. The winding mechanism 2 includes two support plates 201 fixedly installed on the outer surface of the support platform 1. Bearing rings 204 are fixedly embedded on the side of the two support plates 201 that are close to each other. Connecting seats 203 are fixedly connected to the inner rings of both bearing rings 204. The fan covers 501 in the fan assembly 5 can accommodate silent fans 502, which can accelerate the flow of ion air within the elimination hood 4. In addition, the protective mesh plates 503 prevent foreign objects from entering, ensuring stable output of ion air and efficient neutralization of static electricity. The two support plates 201 provide stable support for the winding assembly.

[0025] In a further embodiment, a take-up roller 205 is movably mounted on one side of two connecting seats 203 that are close to each other. A second variable frequency motor 202 is fixedly mounted on the outer surface of a support plate 201. The output end of the second variable frequency motor 202 is fixedly mounted to one end of the take-up roller 205. Through the cooperation of the bearing ring 204 and the connecting seat 203, the take-up roller 205 can be flexibly rotated and disassembled. By driving the rotation of the take-up roller 205 through the second variable frequency motor 202, the release film that has undergone static elimination and wetting treatment can be stably wound up to form a regular film roll, which is convenient for subsequent storage and transportation. A guide cotton plate 14 is fixedly connected to the inner wall of the guide cover 13, and an injection port 1 is opened on the upper surface of the liquid storage tank 10. 1. The guide cotton plate 14 is located above the static eliminator cotton roller 8. Two bearing rings 6 are fixedly embedded in the inner wall of the support cover 3. The inner rings of the two bearing rings 6 are rotatably connected to the outer surfaces of both ends of the static eliminator cotton roller 8. Through the injection port 11, the operator can easily inject the liquid for wetting into the liquid storage tank 10. The guide cotton plate 14 plays a key role in liquid dispersion, which can evenly disperse and penetrate the surface of the static eliminator cotton roller 8, ensuring that the static eliminator cotton roller 8 is always kept moist. Thus, it can continuously and effectively eliminate static electricity of the release film by utilizing the wetting characteristics. The two bearing rings 6 can provide a stable and flexible support structure for the rotation of the static eliminator cotton roller 8, ensuring that the static eliminator cotton roller 8 can rotate smoothly and steadily.

[0026] The working principle of this utility model is as follows: First, liquid for wetting is stored in the storage tank 10. Then, the flow rate is controlled by the quantitative control valve 12, and the liquid is transported to the guide cotton plate 14 through the guide cover 13. The guide cotton plate 14 evenly disperses the liquid and continuously wets the static elimination cotton roller 8. Then, the first frequency conversion motor 9 drives the rotation of the static elimination cotton roller 8, which enables the wet static elimination cotton roller 8 to fully contact the surface of the release film. The wetness further eliminates static electricity. Then, the ion wind bar 7 on the inner wall of the elimination cover 4 generates ion wind, which can initially eliminate static electricity on the surface of the release film. At the same time, the two fan components 5 start to work, which can accelerate the flow of ion wind in the elimination cover 4, improve the static elimination efficiency, and make the static electricity neutralized more quickly. Then, the winding mechanism 2 winds up the release film after static elimination.
