Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of electrostatic removal equipment for thin films, and in particular to an electrostatic removal device for PVC color film. Background Technology
[0002] Static electricity has long been a problem in the production, processing, and use of PVC colored film. Due to the high insulation properties of PVC, friction or separation during processes such as film winding, cutting, printing, or lamination can easily lead to the accumulation of static charge. This accumulation not only causes quality problems such as dust adsorption, edge curling, or adhesion, affecting product appearance and performance, but can also lead to equipment malfunctions or fire hazards due to electrostatic discharge, especially in dry environments or on high-speed production lines.
[0003] Traditional electrostatic eliminators mostly use fixed conductive brushes or grounded rollers, but their limitations are significant:
[0004] Insufficient contact area and adjustment flexibility: The conductive components of traditional devices are in fixed positions, making it difficult to adapt to films of different sizes, shapes or tensions, resulting in insufficient electrostatic contact and unstable static removal effect.
[0005] Poor storage and portability: Conductive components are usually exposed on the outside of the device, taking up space and being easily damaged by impact. There is a lack of effective storage and protection mechanisms when the device is idle or during transportation.
[0006] Low reliability of limiting mechanisms: Existing storage structures mostly rely on simple buckles or friction for fixation, which are prone to loosening due to wear or vibration after long-term use, affecting storage stability.
[0007] High operational complexity: Some devices require tools to adjust the position of conductive components, or multiple steps to complete storage and unfolding, reducing efficiency. To address this, we provide a PVC color filter film electrostatic removal device. Utility Model Content
[0008] To address the aforementioned problems, this invention proposes a PVC color filter film electrostatic removal device, which more accurately solves the problems mentioned in the background art.
[0009] This utility model is achieved through the following technical solution:
[0010] This utility model proposes a PVC color filter film electrostatic removal device, including a support frame and a metal conductive tube fixedly welded to its upper end. A guide groove is laterally formed on the periphery of the metal conductive tube. A metal frame rod is movably connected to the inner wall of the guide groove. A metal sleeve is rotatably sleeved on the periphery of the metal frame rod. A metal sleeve rod is fixedly welded to the periphery of the metal sleeve. A metal insert rod is inserted into the inner wall of the metal sleeve rod. A metal grounding block is fixedly connected to the lower end of the metal insert rod. An opening groove is formed at the port of the metal conductive tube for the metal sleeve rod and the metal insert rod to rotate and be housed inside the metal conductive tube.
[0011] A limiting mechanism is connected between the metal conductive tube and the metal grounding block for limiting the position of the metal sleeve and the metal plug after they are stored.
[0012] The outer thread of the metal sleeve is connected with a torsion screw for adjusting the length of the metal sleeve and the metal insert.
[0013] Furthermore, the limiting mechanism includes a limiting insertion hole opened on the periphery of the end of the metal conductive tube and a rectangular through groove opened on the end of the metal ground contact block. A lap plate is slidably connected to the inner wall of the rectangular through groove. A limiting insertion rod is fixedly installed on the surface of the lap plate. A reset component is connected between the rectangular through groove and the lap plate.
[0014] Furthermore, the reset assembly includes a strip-shaped placement groove formed on the inner side wall of the rectangular through groove, a horizontal fixing rod is fixedly connected between the two end walls of the strip-shaped placement groove, a spring is sleeved around the horizontal fixing rod, and a movable sleeve block is slidably sleeved around the horizontal fixing rod.
[0015] Furthermore, the movable sleeve is slidably connected to the inner wall of the strip-shaped placement groove, and the opposite surfaces of the two movable sleeves are fixedly connected to the two end surfaces of the rectangular through groove.
[0016] Furthermore, one end of the limiting rod is inserted into the inner wall of the limiting hole, and the inner diameter of the limiting hole is compatible with the outer diameter of the limiting rod.
[0017] Furthermore, one end of the spring is fixedly connected to the end wall of the strip-shaped mounting groove, and the other end of the spring is fixedly connected to one end surface of the movable sleeve block.
[0018] The beneficial effects of this utility model are:
[0019] This invention achieves three-dimensional position adjustment of the metal contact block through the lateral sliding of the metal frame rod, the rotational adjustment of the metal sleeve rod, and the telescopic design of the metal insert rod. This allows for precise matching of PVC colored films of different sizes and shapes, ensuring maximum electrostatic contact area and significantly improving electrostatic removal efficiency. Furthermore, in the stored state, the metal sleeve rod and metal insert rod are fully screwed into the metal conductive tube and securely fixed through the precise fit between the limiting insert rod and the limiting hole, preventing accidental slippage or collision damage during transportation or storage, thus balancing functional expandability and portability.
[0020] This invention eliminates the gap problem of traditional snap-fit structures by using a cylindrical, tightly fitting design between the limiting rod and the limiting hole, effectively preventing the metal sleeve and metal rod from wobbling within the conductive tube and avoiding structural wear caused by long-term use. The reset assembly, rigidly connected to the moving block by a spring, ensures that the limiting rod automatically resets and inserts into the limiting hole without external force. Operation requires only one hand to press the overlapping plate to release the limiting position, significantly simplifying the storage and deployment process. This design ensures the device maintains the stability of its limiting function even under frequent use, extending its overall service life. Attached Figure Description

[0025] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.
[0026] Example
[0027] like Figures 1-3As shown in the figure, an embodiment of the present invention discloses a PVC colored film electrostatic removal device, comprising a support frame 1 and a metal conductive tube 2 fixedly welded to its upper end. A guide groove 3 is laterally formed on the periphery of the metal conductive tube 2, and the inner wall of the guide groove 3 is slidably connected to a metal frame rod 4, allowing the metal frame rod 4 to move laterally along the guide groove 3. A metal sleeve 18 is rotatably sleeved around the metal frame rod 4, and a metal sleeve rod 5 is fixedly welded to the periphery of the metal sleeve 18. The inner wall of the metal sleeve rod 5 has a hollow structure, into which a metal insert rod 6 can be inserted, and the lower end of the metal insert rod 6 is fixedly connected to a metal grounding block 7. An opening groove 8 is formed at the end of the metal conductive tube 2, allowing the metal sleeve rod 5 and the metal insert rod 6 to rotate and be stored inside the metal conductive tube 2 when the device is in the retracted state. A limiting mechanism is connected between the metal conductive tube 2 and the metal grounding block 7 to limit and fix the metal sleeve rod 5 and the metal insert rod 6 in the retracted state, preventing them from accidentally sliding out. The metal sleeve 5 has a threaded hole on its periphery, and the torque screw 17 is threadedly connected to the threaded hole. By rotating the torque screw 17, pressure can be applied to the metal insert 6 to adjust and fix the length of the metal sleeve 5 and the metal insert 6.
[0028] When the position of the metal contact block 7 needs to be adjusted, the metal frame rod 4 can be moved laterally while the metal sleeve rod 5 and the metal insertion rod 6 are rotated to a suitable angle. The lengths of the metal sleeve rod 5 and the metal insertion rod 6 can be changed by adjusting the torsion screw 17, ensuring that the metal contact block 7 makes full contact with the PVC colored film to achieve the electrostatic removal function. When the device is not in use, the metal sleeve rod 5 and the metal insertion rod 6 can be rotated and stored inside the metal conductive tube 2, and fixed by the limiting mechanism for easy storage and carrying.
[0029] Furthermore, a limiting insertion hole 9 is opened on the periphery of the end of the metal conductive tube 2, and a rectangular through groove 10 is opened through the end of the metal grounding block 7. The inner wall of the rectangular through groove 10 is slidably connected to the overlapping plate 15, and the limiting insertion rod 16 is fixedly installed on the surface of the overlapping plate 15. A reset component is connected between the rectangular through groove 10 and the overlapping plate 15, which can keep the limiting insertion rod 16 in a specific position when no external force is applied.
[0030] When the metal sleeve 5 and metal plug 6 need to be stored, they are rotated into the metal conductive tube 2, aligning the limiting plug 16 with the limiting socket 9. Under the action of the reset component, the limiting plug 16 automatically inserts into the limiting socket 9, achieving limiting fixation. In the stored state, the limiting plug 16 is stably inserted into the limiting socket 9, effectively preventing the metal sleeve 5 and metal plug 6 from shaking or slipping out inside the metal conductive tube 2, ensuring the stability and reliability of the stored state. When the device needs to be used, simply apply a certain external force to pull the limiting plug 16 out of the limiting socket 9 to release the limiting, which is convenient and quick.
[0031] Furthermore, a strip-shaped placement groove 11 is formed on the inner wall of the rectangular through groove 10, and a horizontal fixing rod 12 is fixedly connected between the two end walls of the strip-shaped placement groove 11. A spring 13 is sleeved around the horizontal fixing rod 12, and a movable sleeve block 14 is slidably sleeved on it. The spring 13 is in a compressed state, providing a restoring force for the movable sleeve block 14; the overlapping plate 15 is fixedly connected to the movable sleeve block 14. When the limiting insertion rod 16 is inserted into the limiting insertion hole 9, the spring 13 is in a naturally extended or slightly compressed state; when it is necessary to pull out the limiting insertion rod 16, an external force is applied to make the overlapping plate 15 drive the movable sleeve block 14 to slide along the horizontal fixing rod 12, and the spring 13 is further compressed, generating a restoring force; when the external force disappears, the restoring force of the spring 13 makes the movable sleeve block 14 drive the overlapping plate 15 and the limiting insertion rod 16 to reset.
[0032] During the use of the device, the reset component ensures that the limit rod 16 can be accurately and stably inserted into the limit socket 9 for limiting. At the same time, when it is necessary to release the limit, it can provide a suitable restoring force so that the limit rod 16 can be pulled out smoothly. The operation is simple and the limiting effect is good, which improves the convenience and reliability of the device.
[0033] Furthermore, the shape of the movable sleeve 14 is adapted to the inner wall shape of the strip-shaped placement groove 11, so that the movable sleeve 14 can slide stably on the inner wall of the strip-shaped placement groove 11. The opposite surfaces of the two movable sleeves 14 are respectively fixedly connected to the two end surfaces of an overlapping plate 15, ensuring that the overlapping plate 15 remains horizontal during movement, so that the limiting insertion rod 16 can be accurately inserted into the limiting insertion hole 9.
[0034] When an external force is applied to move the overlapping plate 15, the moving sleeve 14 slides smoothly on the inner wall of the strip-shaped placement groove 11, driving the limiting rod 16 to accurately insert or pull out the limiting insertion hole 9, avoiding limiting failure or operational difficulties caused by unstable movement, and improving the overall performance of the device.
[0035] Furthermore, one end of the limiting rod 16 is designed to be cylindrical, with its outer diameter precisely calculated to match the inner diameter of the limiting socket 9. When the limiting rod 16 is inserted into the limiting socket 9, the two fit tightly together without any obvious gaps, effectively preventing the metal sleeve 5 and the metal rod 6 from shaking inside the metal conductive tube 2.
[0036] Through this adaptive design, the limiting rod 16 can be reliably inserted into the limiting hole 9 to achieve a stable limiting effect. This ensures that the positions of the metal sleeve rod 5 and the metal plug rod 6 are fixed when the device is stored, avoiding damage to the internal structure of the device that may be caused by shaking. It also ensures the safety of the device during carrying and storage.
[0037] Furthermore, one end of the spring 13 is fixedly connected to the end wall of the strip-shaped mounting groove 11 by welding or other fixing methods, and the other end is also fixedly connected to one end surface of the movable sleeve 14 by the same fixing method. When the movable sleeve 14 slides in the strip-shaped mounting groove 11, the spring 13 will undergo elastic deformation and generate a restoring force.
[0038] This connection method enables the spring 13 to stably provide restoring force to the moving sleeve 14, ensuring that the limit rod 16 can automatically reset when needed. During operation, the elastic deformation and return process of the spring 13 is smooth and reliable, ensuring the normal functioning of the limit mechanism and improving the user experience and reliability of the device.
