Description

Technical Field

[0001] This utility model relates to the field of plastic film technology, specifically to an electrostatic elimination device for plastic film production. Background Technology

[0002] Plastic film is a thin, continuous polymer material. Thicker plastic films are often referred to as "sheets." These films are used to divide areas or volumes, fix items, act as barriers, or serve as printable surfaces. Static electricity is a common problem in the production, processing, and transportation of plastic films. Static electricity is caused by the charging or imbalance of charges on the surface of an object. When two non-conductive objects rub against each other, electrons transfer from one object to the other, causing the surfaces to become charged, thus generating static electricity. The accumulation of static electricity can have a series of negative effects on film products, such as adhesion and dust attraction.

[0003] Most existing static eliminators use ion blowers to eliminate static electricity from plastic films. However, ion blowers can usually only eliminate static electricity on one side of the plastic film, requiring secondary static elimination, which makes the device impractical. In addition, the plastic film may become dusty after static elimination, and failure to deal with it in time may affect the quality of the plastic film. Utility Model Content

[0004] To address the issues that ion blowers typically only eliminate static electricity on one side of plastic film and that dust contamination on plastic film can affect its quality, this invention aims to provide a static electricity elimination device for plastic film production.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a static electricity elimination device for plastic film production, comprising an installation body and an ion fan body. Multiple evenly distributed support legs are fixedly connected to the outer surface of the installation body. The top ends of the support legs are fixedly connected to the outer surface of the ion fan body. A synchronous cleaning component is provided on the outer surface of the installation body. A first blowing plate is fixedly connected to the outer surface of the ion fan body. A hollow plate is symmetrically slidably connected inside the first blowing plate. A second blowing plate is slidably connected to the end of the hollow plate away from the first blowing plate. A sliding groove plate is fixedly connected to the outer surface of the first blowing plate. A slider is fixedly connected to the outer surface of the second blowing plate. The outer surface of the slider is slidably connected to the inside of the sliding groove plate. Multiple evenly distributed fixing holes are opened on the outer surface of the sliding groove plate. The inside of the first blowing plate is connected to the inside of the hollow plate, and the inside of the hollow plate is connected to the inside of the second blowing plate. A feeding roller is rotatably connected to the outer surface of the installation body. An insert rod is slidably inserted into the fixing hole, and the outer surface of the insert rod is slidably inserted into the middle of the slider.

[0006] Preferably, the synchronous cleaning assembly includes a first gear, a long strip plate symmetrically fixedly connected to the outer surface of the mounting body, a first cleaning roller rotatably connected to the outer surface of the long strip plate, a second cleaning roller rotatably connected to the outer surface of the long strip plate, a middle part of the first gear fixedly connected to the outer end of the first cleaning roller, a receiving roller rotatably connected to the outer surface of the mounting body, a first transmission wheel fixedly connected to the outer end of the receiving roller, a second transmission wheel fixedly connected to the outer end of the first cleaning roller, a second gear fixedly connected to the outer surface of the second cleaning roller, the outer surface of the second gear meshing with the outer surface of the first gear, a transmission belt sleeved on the outer surface of the first transmission wheel, the inner side of the transmission belt sleeved with the outer surface of the second transmission wheel, a spring fixedly connected to the inner side of the slide plate, the end of the spring away from the slide plate fixedly connected to the slider, a motor fixedly connected to the outer surface of the mounting body, and one end of the motor output shaft fixedly connected to the outer end of the receiving roller.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0008] 1. By setting the linkage between the slider and the slide plate, the moving second air blower causes the slider to move inside the slide plate. At the same time, the movement of the second air blower causes the hollow plate to move into the second air blower and the first air blower, so that the gap between the second air blower and the first air blower can be adjusted, thereby better eliminating static electricity on both sides of the plastic film as needed.

[0009] 2. By setting up a synchronous cleaning component, the rotation of the first transmission wheel causes the second transmission wheel to rotate via a transmission belt, which in turn drives the first cleaning roller to rotate. The rotation of the first cleaning roller drives the first gear to rotate, which in turn causes the second cleaning roller to rotate synchronously. This allows the second cleaning roller and the first cleaning roller to clean the plastic film after static electricity removal, preventing dust from affecting the quality of the plastic film.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] Example: Figure 1-6As shown, this utility model provides an electrostatic elimination device for plastic film production, including a mounting body 1 and an ion fan body 2. Multiple evenly distributed support legs 7 are fixedly connected to the outer surface of the mounting body 1, with the top ends of the support legs 7 fixedly connected to the outer surface of the ion fan body 2. A synchronous cleaning component is provided on the outer surface of the mounting body 1. A first blowing plate 10 is fixedly connected to the outer surface of the ion fan body 2. A hollow plate 11 is symmetrically slidably connected inside the first blowing plate 10. A second blowing plate 12 is slidably connected to the end of the hollow plate 11 away from the first blowing plate 10. The outer surface of the first blowing plate 10... A sliding plate 14 is fixedly connected to the surface of the first air blower 12, and a slider 16 is fixedly connected to the outer surface of the second air blower 12. The outer surface of the slider 16 is slidably connected to the inside of the sliding plate 14. The outer surface of the sliding plate 14 has multiple evenly distributed fixing holes 15. The ion blower body 2 is a prior art technology. The ion blower body 2 generates positive and negative ions by corona discharge through the internal needle-like (filamentous) discharge medium under the action of high voltage. The built-in fan blows out the ionized air to form an ion wind that adsorbs and neutralizes the static charge on the surface of the plastic film. The positive and negative ions react with the static charge on the surface of the film. The combination of positive and negative charges eliminates static electricity. By linking the slider 16 and the slide plate 14, the movement of the second blowing plate 12 causes the slider 16 to move inside the slide plate 14. Simultaneously, the movement of the second blowing plate 12 moves the hollow plate 11 towards the interior of both the second and first blowing plates 12 and 10, allowing adjustment of the gap between them. This enables better elimination of static electricity on both sides of the plastic film as needed. A spring 18 is fixedly connected to the inner side of the slide plate 14, with the end of the spring 18 away from the slide plate 14 fixedly connected to the slider 16. The slider 16 can move stably inside the slide plate 14. The inside of the first blowing plate 10 is connected to the inside of the hollow plate 11, and the inside of the hollow plate 11 is connected to the inside of the second blowing plate 12, so that the ion wind can enter the inside of the second blowing plate 12 through the hollow plate 11. The outer surface of the mounting body 1 is rotatably connected to the feeding roller 3, so that the plastic film can be placed on the feeding roller 3. The insertion rod 17 is slidably inserted into the fixing hole 15. The outer surface of the insertion rod 17 is slidably inserted into the middle of the slider 16, so that the insertion rod 17 can be moved out of the slider 16 and the fixing hole 15 and no longer fix the slider 16.

[0020] The synchronous cleaning assembly includes a first gear 19, a long strip plate 6 symmetrically fixedly connected to the outer surface of the mounting body 1, a first cleaning roller 8 rotatably connected to the outer surface of the long strip plate 6, a second cleaning roller 13 rotatably connected to the outer surface of the long strip plate 6, a middle part of the first gear 19 fixedly connected to the outer end of the first cleaning roller 8, a receiving roller 4 rotatably connected to the outer surface of the mounting body 1, a first transmission wheel 22 fixedly connected to the outer end of the receiving roller 4, a second transmission wheel 21 fixedly connected to the outer end of the first cleaning roller 8, and a second gear 20 fixedly connected to the outer surface of the second cleaning roller 13. The outer surface of the second gear 20 meshes with the outer surface of the first gear 19. By setting the first gear 19, the first transmission wheel 22 rotates, causing the second transmission wheel 13 to rotate via the transmission belt 9. 1. Rotation drives the first cleaning roller 8 to rotate. The rotation of the first cleaning roller 8 drives the first gear 19 to rotate and, through the second gear 20, causes the second cleaning roller 13 to rotate synchronously. This allows the second cleaning roller 13 and the first cleaning roller 8 to clean the plastic film after static electricity removal, preventing dust from affecting the quality of the plastic film. The outer surface of the first transmission wheel 22 is fitted with a transmission belt 9. The inner side of the transmission belt 9 is connected to the outer surface of the second transmission wheel 21, so that the rotation of the first transmission wheel 22 can drive the rotation of the second transmission wheel 21 through the transmission belt 9. The outer surface of the mounting body 1 is fixedly connected to a motor 5. One end of the output shaft of the motor 5 is fixedly connected to the outer end of the take-up roller 4, so that the motor 5 can control the rotation of the take-up roller 4 to control the movement of the plastic film.

[0021] Working principle: Before static electricity elimination, the operator pulls out the plug 17, removing it from the slider 16 and fixing hole 15, thus no longer fixing the slider 16. Then, the second blower plate 12 is moved, causing the slider 16 to move inside the slide plate 14. Simultaneously, the movement of the slider 16 applies pressure to the spring 18, causing it to contract. The movement of the second blower plate 12 also moves the hollow plate 11 into the space between the second blower plate 12 and the first blower plate 10, allowing adjustment of the gap between them. This enables better static electricity elimination on both sides of the plastic film as needed. Then, the ion fan body 2 is activated. Under high voltage, the internal needle-like (filamentous) discharge medium of the ion fan body 2 undergoes corona discharge, ionizing the surrounding air to generate positive and negative ions. The built-in fan blows out ionized air, creating an ionized wind that adsorbs and neutralizes the static charge on the surface of the plastic film. Positive and negative ions combine with the positive and negative charges on the film surface, thereby eliminating static electricity. The motor 5 is started, and the output shaft of the motor 5 rotates, driving the take-up roller 4 to rotate. The rotation of the take-up roller 4 moves the plastic film. At the same time, the rotation of the take-up roller 4 drives the first transmission wheel 22 to rotate. The rotation of the first transmission wheel 22 drives the second transmission wheel 21 to rotate through the transmission belt 9. The rotation of the second transmission wheel 21 drives the first cleaning roller 8 to rotate. The rotation of the first cleaning roller 8 drives the first gear 19 to rotate. The rotation of the first gear 19 drives the second cleaning roller 13 to rotate synchronously through the second gear 20. Thus, the second cleaning roller 13 and the first cleaning roller 8 can clean the plastic film after the static electricity has been eliminated, preventing dust from affecting the quality of the plastic film.
