Description

Technical Field

[0001] This utility model relates to the field of PE film production, specifically to a PE film antistatic cleaning device. Background Technology

[0002] PE film (polyethylene film) is a lightweight, flexible, and insulating plastic film widely used in packaging, agriculture, and other fields. However, due to its low conductivity and friction, PE film is prone to generating static electricity during production and use, leading to problems such as dust attraction, operational difficulties, safety hazards, and equipment damage.

[0003] In the prior art, publication number "CN217191101U" discloses a PE film antistatic cleaning device, which includes a drive motor, a linkage track, PE film sleeve rollers, an antistatic pressure component, and an antistatic cleaning plate. The internal structure of the antistatic cleaning device housing has a battery placement slot, and a battery compartment switch door is movably installed on the right side of the battery placement slot. The PE film to be antistatic and cleaned is sleeved onto the PE film sleeve rollers, and the PE film is passed through the antistatic pressure component and sleeved onto the second set of PE film sleeve rollers. The drive motor rotates, driving the linkage track to rotate, causing the two sets of passive rotating shafts to rotate counterclockwise simultaneously, transferring the PE film sleeved on the first set of PE film sleeve rollers to the second set of PE film sleeve rollers, thus achieving automated antistatic treatment of the PE film. At the same time, the antistatic pressure component and the antistatic cleaning plate are equipped with corresponding cleaning components, so that the PE film is cleaned while being antistatic.

[0004] However, existing technologies still have significant shortcomings. Traditional PE film antistatic cleaning devices typically use fixed electrostatic brushes. Due to static contact, fixed electrostatic brushes do not provide a thorough cleaning effect and can easily leave static residue on the PE film surface. They cannot evenly conduct away static charges, affecting the comprehensiveness and uniformity of the cleaning. Utility Model Content

[0005] The purpose of this invention is to provide a PE film antistatic cleaning device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a PE film antistatic cleaning device, comprising a support frame, the support frame including pillars and arms, a cleaning platform connected between two pillars, an arc end provided at the front and back of the cleaning platform, the arc end being arc-shaped, an electrostatic brush provided on the top surface of the cleaning platform, the electrostatic brush contacting the top surface of the cleaning platform, a brush handle fixed to the top surface of the electrostatic brush, sleeve arms respectively installed on both sides of the top surface of the brush handle, the sleeve arms being screwed to the top surface of the brush handle, and a limit roller connected between the two arms.

[0007] Preferably, the arm is located on the surface of the support column, and the arm is bolted to the surface of the support column, and the two ends of the limiting roller are connected to the connection of the arm with bearings.

[0008] Preferably, a measuring plate is connected near the back of the support column, and a distance measuring element is installed at the center of the measuring plate, with the measuring end of the distance measuring element facing the top surface of the cleaning platform.

[0009] Preferably, the limiting roller is located near the front and back of the cleaning platform, and the limiting roller is located at the bottom of the cleaning platform.

[0010] Preferably, the sleeve is fitted onto the surface of the top of the support column, and the sleeve is slidably connected to the surface of the top of the support column.

[0011] Preferably, a reciprocating cylinder is bolted to the side of the support column, and a movable joint is fixed to the telescopic end of the reciprocating cylinder, and the movable joint is connected and fixed to the sleeve arm.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] Using a reciprocating electrostatic brush to clean the PE film enhances the cleaning effect. The length of the electrostatic brush is equal to the width of the PE film. Compared with a fixed electrostatic brush, the dynamic electrostatic brush can more thoroughly conduct away the static charge on the surface of the PE film through reciprocating back-and-forth motion, reducing static residue and ensuring a more uniform and comprehensive cleaning effect. At the same time, the back-and-forth motion of the dynamic electrostatic brush makes the bristle wear more even. The reciprocating back-and-forth motion of the dynamic electrostatic brush can more effectively clean the surface of the PE film, adapt to high-speed production lines, improve cleaning efficiency, and ensure stable electrostatic cleaning effect.

[0014] By mounting the limiting roller, cleaning platform, and electrostatic brush on the same bracket, the device structure becomes more compact, saving space and facilitating installation and maintenance. The coordinated work of the electrostatic brush, cleaning platform, and limiting roller ensures that the membrane remains flat and stable on the cleaning platform, improving the efficiency of electrostatic cleaning. This ensures that the membrane can be smoothly guided from the limiting roller into the cleaning platform, reducing membrane vibration or deviation, ensuring a stable membrane running path, and making its entry and exit from the cleaning platform smoother.

[0020] 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.

[0021] Please see Figure 1-4 This utility model provides a technical solution:

[0022] Example 1: A PE film antistatic cleaning device: It includes a support 1, which comprises a pillar 11 and an arm 12. A cleaning platform 4 is connected between the two pillars 11. An electrostatic brush 6 is provided on the top surface of the cleaning platform 4, and the electrostatic brush 6 is in contact with the top surface of the cleaning platform 4. During the production process, static electricity in the PE film can cause dust to adhere, affecting product quality. Therefore, the electrostatic brush 6 removes static electricity from the film during production. The bristles of the electrostatic brush 6 are made of conductive materials such as carbon fiber, metal wire, or conductive plastic, and contact the surface of the PE film to conduct away the static charge. The electrostatic brush 6 is also equipped with a grounding device, which is connected to a grounding wire to ensure that the charge can be smoothly released to the ground. Typically, this is achieved using... The device is made of conductive materials such as copper or aluminum wire. The charge carried away by the electrostatic brush 6 is released to the ground through the grounding wire. A limiting roller 3 is connected between the two arms 12. The arms 12 are located on the surface of the support column 11 and are bolted to the surface of the support column 11. The two ends of the limiting roller 3 are connected to the connection of the arms 12 by bearings. The bracket 1 of the device consists of the support column 11 and the arms 12. The limiting roller 3 is located between the two arms 12 and is distributed on the front and back of the cleaning platform 4. The height of the limiting roller 3 is lower than that of the cleaning platform 4. The PE film is attached to the bottom of the limiting roller 3 on the front side. After passing through the cleaning platform 4, the top surface of the film is electrostatically removed and cleaned by the electrostatic brush 6 above the cleaning platform 4, and then it is attached to the bottom surface of the limiting roller 3 on the back side and rolled up.

[0023] To further explain, when the film is wound up during production, the repeated movement of the electrostatic brush 6 enhances the cleaning effect, more thoroughly removing static charge from the PE film surface, reducing static residue, and ensuring a more uniform and comprehensive cleaning effect. Simultaneously, it makes the brush bristle wear more even, avoiding the localized wear problem caused by long-term fixed contact of the fixed electrostatic brush 6, thus extending the service life of the electrostatic brush 6. This cleaning method is suitable for high-speed production lines, improving cleaning efficiency. The limiting roller 3, cleaning platform 4, and electrostatic brush 6 are located on the same bracket 1, making the device structure more compact, saving space, and facilitating installation and maintenance. The coordinated work of the electrostatic brush 6 with the cleaning platform 4 and limiting roller 3 ensures that the film remains flat and stable on the cleaning platform 4, improving the efficiency of electrostatic cleaning.

[0024] A brush handle 7 is fixed to the top surface of the electrostatic brush 6. Sleeve arms 8 are installed on both sides of the top surface of the brush handle 7, and the sleeve arms 8 are fixed to the top surface of the brush handle 7 with screws. The sleeve arms 8 are sleeved on the top surface of the support column 11, and the sleeve arms 8 are slidably connected to the top surface of the support column 11. A reciprocating cylinder 9 is bolted to the side of the support column 11. A movable joint 10 is fixed to the telescopic end of the reciprocating cylinder 9, and the movable joint 10 is connected and fixed to the sleeve arms 8. It should be noted that the telescopic end of the reciprocating cylinder 9 can move repeatedly. By driving the sleeve arms 8 together with the brush handle 7 and the electrostatic brush 6 through the movable joint 10, the electrostatic treatment of the top surface of the membrane can be completed. The sleeve arms 8 are sleeved on the top surface of the support column 11 and can slide along the top surface of the support column 11. The cooperation between the two can limit the movement of the sleeve arms 8.

[0025] Example 2:

[0026] Based on Embodiment 1, the cleaning platform 4 is provided with arc-shaped ends 5 at both the front and back positions. It is worth noting that the addition of the limiting roller 3 and the arc-shaped ends 5 of the cleaning platform 4 effectively limits the PE film during cleaning, ensuring the film can pass through the device for processing. The arc-shaped design of the ends 5 avoids contact between sharp edges and the film, reducing surface damage caused by friction or scratching during production. This ensures the film is smoothly guided from the limiting roller 3 into the cleaning platform 4, reducing film vibration or deviation and ensuring a stable film path for entry and exit from the cleaning platform. The process is smoother, preventing the film from accumulating or getting stuck at the edges, thus improving production efficiency. The position of the limiting roller 3 is located near the front and back of the cleaning platform 4, and the limiting roller 3 is located at the bottom of the cleaning platform 4. The limiting roller 3 is located below the cleaning platform 4, which can effectively limit the left and right movement of the film and ensure that the film maintains a stable running path on the cleaning platform 4. The design of the limiting roller 3 prevents the film from shifting or running off course during production, ensuring that the film is always in the center position of the cleaning platform 4. The positioning function of the limiting roller 3 keeps the film flat on the cleaning platform 4, ensuring that the electrostatic brush 6 can evenly contact the surface of the film and improve the cleaning effect.

[0027] A measuring plate 13 is connected to the back of the support column 11. A distance measuring element 2 is installed at the center of the measuring plate 13, and the measuring end of the distance measuring element 2 faces the top surface of the cleaning platform 4. The measuring plate 13 on the bracket 1 is the mounting bracket of the distance measuring element 2. The distance measuring element 2 is a laser distance measuring instrument. The distance from the produced PE film to the distance measuring element 2 can be monitored by laser distance measurement. When an accident occurs in production and the thickness of the film deviates from the set thickness, the number detected by the distance measuring element 2 will change. At this time, the machine can be stopped and an alarm can be issued to remind the staff to check or adjust the equipment.

[0028] Working Principle: During the production process, static electricity can cause PE film to attract dust, affecting product quality. Therefore, during film production, an electrostatic brush 6 removes static electricity from the film. As the film is wound up during production, the repeated movement of the electrostatic brush 6 enhances the cleaning effect, more thoroughly dissipating static charges from the PE film surface, reducing static residue, and ensuring a more uniform and comprehensive cleaning effect. The PE film is attached to the bottom of the front limiting roller 3, passes through the cleaning platform 4, and undergoes static removal cleaning of the top surface of the film by the electrostatic brush 6 above the cleaning platform 4. It is then attached to the bottom surface of the back limiting roller 3 and wound up. The limiting roller 3, cleaning platform 4, and electrostatic brush 6 are located on the same bracket 1, making the device structure more compact, saving space, and facilitating installation and maintenance. The coordinated work of the electrostatic brush 6, cleaning platform 4, and limiting roller 3 ensures that the film remains flat and stable on the cleaning platform 4, improving the efficiency of electrostatic cleaning.
