Description

Technical Field

[0001] This invention belongs to the technical field of thin film processing equipment, specifically a thin film antistatic winding device. Background Technology

[0002] In the production and processing of precision films such as electronic films and optical films, the winding process is a crucial step, as its quality directly determines the performance of the finished film and its subsequent use. As a polymer insulating material, the film inevitably comes into contact with, separates from, and rubs against components such as guide rollers and winding shafts of the equipment during unwinding, transport, and rewinding, which generates static charge that accumulates on the surface, creating a potential static electricity hazard.

[0003] Publication No. CN218809312U discloses an optimized structure for online electrostatic elimination during polyester film winding, comprising a film roll, a rubber guide roller, and a winding roller, wherein the film roll and the rubber guide roller are arranged horizontally and closely against each other; an ion electrostatic elimination bar is provided on the side near the rubber guide roller, with the inner common tangent between the film roll and the rubber guide roller as the boundary, and the ion electrostatic elimination bar is located on the opposite side of the winding direction of the rubber guide roller. This utility model, by placing the ion electrostatic elimination bar at the angle between the rubber guide roller and the film roll, can efficiently, quickly, and cost-effectively eliminate static electricity on the film surface, greatly reducing the static electricity of the film roll layers being wound and stacked, and better solving the static electricity hazards in the subsequent application and reprocessing of polyester film in various fields, avoiding the adsorption and contamination of the film by a large amount of dust.

[0004] In the above-mentioned technologies, although ion static elimination rods can be set at the angle between the rubber guide roller and the film roll to eliminate static electricity on the film surface efficiently, quickly and at low cost, for wide films, such as >1m, a single ion rod is prone to insufficient edge coverage, requiring multiple rods to be connected in parallel or dynamically adjusted, which increases cost and deployment difficulty.

[0005] To address the problems mentioned in the background section, the present invention provides a thin film antistatic winding device.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a film antistatic winding device, comprising a winding device, an antistatic mechanism installed on the winding device, a positioning component provided on the antistatic mechanism, and a flow guiding component installed on the side of the antistatic mechanism; The winding equipment includes a main body with a mounting frame, and a thin film is wound inside the main body of the equipment. The antistatic mechanism includes a main antistatic rod fixed to the bottom of the mounting frame by a pair of connecting rods, and the main antistatic rod is located above the film. The bottom of the main antistatic rod has several first air holes. The two ends of the main antistatic rod are detachably connected to auxiliary antistatic rods. The bottom of the auxiliary antistatic rod has several second air holes. The flow guiding assembly includes mounting bases symmetrically fixed at both ends of the main antistatic bar and the auxiliary antistatic bar. A card is inserted into the mounting base, and a flow guiding plate is fixedly connected to the top of the card. The positioning component includes a pair of sliding grooves fixed to the side walls at both ends of the main antistatic bar. A bidirectional lead screw is rotatably connected in one of the sliding grooves, and a sliding rod is fixedly connected in the other sliding groove. A pair of L-shaped plates are symmetrically fitted on the bidirectional lead screw and the sliding rod. Limiting plates are fixedly connected to one end of each pair of L-shaped plates away from each other.

[0009] Preferably, each of the two limiting plates has anti-slip particles fixedly connected to one end of each other.

[0010] Preferably, a clamping plate is movably connected inside the mounting base, and several compression springs are fixedly connected between the clamping plate and the inner wall of the mounting base away from the antistatic bar, and a retaining plate is engaged between the clamping plate and the inner wall of the mounting base.

[0011] Preferably, the first air pore at the bottom of the main antistatic bar is arranged in a non-uniform pattern with sparser pores in the middle and denser pores on both sides, and the second air pore has the same density as the two sides of the first air pore.

[0012] Preferably, the guide plate is designed in an arc shape, and the bottom end of the guide plate is flush with the two ends of the antistatic bar.

[0013] Preferably, the bottom end of the guide plate has an inner cavity, and an arc-shaped protective plate is slidably connected in the inner cavity.

[0014] Preferably, the two auxiliary antistatic bars are detachably connected to magnetic plates at their side ends, and both the guide plate and the sealing plate are made of magnetic material, and the magnetic plates are magnetically attracted to the cross sections of the guide plate and the sealing plate.

[0015] Preferably, both the main antistatic bar and the auxiliary antistatic bar have internal air channels, and the main antistatic bar has open ends.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention precisely measures the total length of the required antistatic rods based on the actual width of the film, flexibly selects auxiliary and main antistatic rods for modular splicing, and uses a bidirectional screw drive mechanism to drive the synchronous movement of the limiting plates on both sides, thereby firmly clamping and fixing the spliced ​​antistatic rods. Subsequently, a special card plate equipped with a guide plate is accurately inserted into the preset mounting base, thus completing the rapid and reliable assembly of the entire antistatic component. During operation, ionized dry air is continuously introduced into the air passages inside the antistatic rods. The ionized air is evenly released through the air holes arranged in a density pattern on the surface, effectively neutralizing the static charge accumulated on the film surface. The specially designed guide plate can guide the airflow to be discharged in an orderly and stable manner along a predetermined direction, preventing uneven static elimination caused by airflow turbulence. This method achieves flexible adaptation and comprehensive coverage for films of different widths, especially eliminating the static dead zones that often appear at the edge areas of wide films. It eliminates the need for a complex deployment of multiple sets of equipment in parallel, significantly reducing equipment purchase costs and the difficulty of on-site installation and commissioning.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1 to 6 As shown, the present invention provides a film antistatic winding device, including a winding device 1, an antistatic mechanism 2 installed on the winding device 1, a positioning component 4 provided on the antistatic mechanism 2, and a flow guiding component 3 installed on the side of the antistatic mechanism 2. The winding equipment 1 includes a main body 101 on which a mounting frame 102 is installed, and a film 103 is wound inside the main body 101; The antistatic mechanism 2 includes a main antistatic rod 202 fixed to the bottom of the mounting frame 102 by a pair of connecting rods 201, and the main antistatic rod 202 is located above the film 103. The bottom of the main antistatic rod 202 is provided with a number of first air holes 205. The two ends of the main antistatic rod 202 are detachably connected to a secondary antistatic rod 203. The bottom of the secondary antistatic rod 203 is provided with a number of second air holes 206. The flow guiding component 3 includes mounting bases 301 symmetrically fixed at both ends of the main antistatic bar 202 and the auxiliary antistatic bar 203. A card plate 302 is inserted into the mounting base 301, and a flow guiding plate 303 is fixedly connected to the top of the card plate 302. The positioning component 4 includes a pair of slide grooves 401 fixed on the side walls of both ends of the main antistatic bar 202. A bidirectional lead screw 402 is rotatably connected in one slide groove 401, and a slide rod 406 is fixedly connected in the other slide groove 401. A pair of L-shaped plates 403 are symmetrically sleeved on the bidirectional lead screw 402 and the slide rod 406. Limiting plates 404 are fixedly connected to one end of each pair of L-shaped plates 403 away from each other.

[0020] The bottom end of the bidirectional lead screw 402 passes through the slide groove 401, and a knob 405 is fixedly connected to the bottom end of the bidirectional lead screw 402. Both the main antistatic rod 202 and the auxiliary antistatic rod 203 are provided with air passages, and the two ends of the main antistatic rod 202 are designed to be open.

[0021] Using the above scheme: When winding the film 103, firstly, a secondary antistatic bar 203 of appropriate length needs to be selected according to the actual width of the film 103. Then, the secondary antistatic bar 203 is assembled with both ends of the main antistatic bar 202. During the assembly process, the operator can rotate the knob 405 to drive the bidirectional lead screw 402 to rotate. The rotation of the bidirectional lead screw 402 will drive a pair of symmetrically arranged L-shaped plates 403 on it to move synchronously towards or in opposite directions along the slide groove 401. At the same time, the L-shaped plates 403 on the slide rod 406 also move synchronously, thereby driving the two limiting plates 404 to adjust to the appropriate position corresponding to the assembly. Next, the secondary antistatic bar 203 and the main antistatic bar 202 are accurately connected, and then the knob 405 is rotated in the opposite direction to bring the two limiting plates 404 closer to each other, thereby aligning the main antistatic bar 202. The main antistatic bar 202 and the auxiliary antistatic bar 203 are firmly clamped and fixed at their joints, thus completing the entire assembly process. After assembly, ionized dry air is introduced into the air passages inside the main antistatic bar 202 and the auxiliary antistatic bar 203. This air is then evenly sprayed out through the first air hole 205 and the second air hole 206, respectively, directly acting on the surface of the film 103 to effectively neutralize the static electricity on the surface of the film 103. During this process, the specially designed guide plates 303 on both sides can significantly reduce airflow turbulence, thereby reducing its impact on the stability of the film 103 during the conveying process. By adopting this modular design, the main antistatic bar 202 and the auxiliary antistatic bar 203 can be flexibly matched to meet the needs of films 103 of different widths. The overall length can be flexibly adjusted according to the actual production situation, greatly enhancing the adaptability and application flexibility of the equipment.

[0022] like Figures 3 to 4 As shown, the top ends of the main antistatic bar 202 and the auxiliary antistatic bar 203, which are close to each other, are symmetrically fixed with a pair of slots 407. The bottom end of the upper limiting plate 404 is fixedly connected with a block 408 corresponding to the slot 407, and the block 408 engages with the slot 407. The two limiting plates 404, which are close to each other, are fixedly connected with particles for anti-slip.

[0023] The above-mentioned solution is adopted: During the splicing process of the main antistatic bar 202 and the auxiliary antistatic bar 203, after the limiting plate 404 completes the clamping and fixing operation of the splicing joint, the locking block 408 located on the limiting plate 404 can accurately align and lock into the corresponding slot 407. This design effectively improves the connection stability between the limiting plate 404 and the antistatic bar body, thereby avoiding the possible displacement or loosening of the limiting plate 404 during continuous operation or vibration of the equipment, ensuring the firmness and reliability of the entire splicing structure in long-term use. At the same time, the surface of the limiting plate 404 is distributed with uniform anti-slip particle texture. These particles can significantly increase the frictional resistance between the limiting plate 404 and the bar body splicing contact surface, further enhancing the fixing effect and preventing the antistatic bar body from shifting or deviating in the splicing position during operation or under force, ensuring the smooth and continuous operation of the entire static elimination process.

[0024] like Figures 2 to 5 As shown, a clamping plate 307 is movably connected inside the mounting base 301. Several compression springs 308 are fixedly connected between the clamping plate 307 and the inner wall of the mounting base 301 away from the antistatic bar. A clamping plate 302 is clamped between the clamping plate 307 and the inner wall of the mounting base 301. The first air hole 205 at the bottom of the main antistatic bar 202 is arranged in a non-uniform manner with sparser holes in the middle and denser holes on both sides. The second air hole 206 has the same density as the two sides of the first air hole 205. The guide plate 303 is designed in an arc shape, and the bottom end of the guide plate 303 is flush with the two ends of the antistatic bar.

[0025] With the above solution: when the clamping plate 302 is inserted into the mounting base 301 for installation and fixation, the clamping plate 307, under the continuous elastic force applied by the compression spring 308, can tightly squeeze and hold the clamping plate 302. This elastic clamping design allows the device to flexibly adapt to clamping plates 302 of different thicknesses, thereby achieving a stable and reliable fixing effect, significantly improving the compatibility and adaptability of the equipment to clamping plates 302 of different specifications. At the same time, relying on the elastic buffering effect provided by the compression spring 308, this structure can effectively form shock absorption protection for the entire antistatic bar, significantly reducing the interference of vibration transmitted from the external environment on the working state and performance of the antistatic bar, and ensuring its continuous and stable operation. On the other hand, the first vent 205 adopts a differentiated arrangement with sparser vents in the middle and denser vents on both sides. This layout design is specifically optimized for the characteristics of the edge area of ​​the film 103 during the winding process, which is more prone to static charge accumulation due to more frequent frictional contact. By setting denser vents in the edge area of ​​the film 103 with a larger static charge generation, a stronger and more concentrated airflow can be provided, thereby discharging static electricity more efficiently. Combined with the synergistic operation of the second vent 206, a more uniform and comprehensive static electricity elimination effect is achieved in the width direction of the entire film 103, improving the overall integrity and consistency of static electricity neutralization. In addition, the arc-shaped guide plate 303 can smoothly and evenly guide the high-speed airflow blown out of the air hole to both sides of the film 103, making the airflow more evenly distributed on the surface of the film 103. This effectively avoids problems such as instability, wrinkling or deviation of the film 103 during the winding process that may be caused by airflow turbulence or local impact. At the same time, the bottom end of the guide plate 303 is designed to be strictly flush with the two ends of the antistatic bar, ensuring that the guided airflow can completely cover the entire width of the film 103, preventing insufficient airflow coverage or blind spots in the edge area of ​​the film 103, thereby ensuring the full-width effectiveness of the static elimination effect.

[0026] like Figure 2 As shown, the bottom end of the guide plate 303 has an inner cavity, in which an arc-shaped protective plate 304 is slidably connected. A magnetic strip 305 is fixedly connected to the end of the protective plate 304 away from the guide plate 303, and the two magnetic strips 305 attract each other. The two auxiliary antistatic rods 203 are detachably connected to magnetic plates 306 on their sides. Both the guide plate 303 and the sealing plate 204 are made of magnetic material, and the magnetic plates 306 are magnetically attracted to the cross sections of the guide plate 303 and the sealing plate 204.

[0027] Using the above scheme: Without activating the anti-static mechanism 2, the operator needs to smoothly pull the protective plate 304 downwards along its installation track until it is completely removed. During this process, with the help of the magnetic force generated by the two magnetic strips 305 pre-set on the mating edges of the protective plate 304, when the two protective plates 304 are pulled to the appropriate position, the magnetic strips 305 will immediately attract each other, automatically adsorb and tightly fit together, thus firmly splicing the originally separate protective plates 304 into a complete, continuous arc-shaped protective cover. This arc-shaped protective cover is carefully designed so that its internal space can completely cover and enclose the main anti-static rod 202 and the two auxiliary anti-static rods 203 located on both sides. Then, the operator needs to... Two magnetic plates 306 are respectively located near the sealing plates 204 on the sides of the two auxiliary antistatic bars 203. Utilizing the inherent attraction between magnetic materials, the magnetic plates 306 and the sealing plates 204 are firmly attracted together. This step achieves effective sealing and reliable enclosure of the entire arc-shaped protective cover, which can significantly prevent dust, impurities, and fine particles from the external environment from accumulating and depositing on the surface of the antistatic bar assembly during equipment idle or non-working periods. At the same time, the robust arc-shaped cover can also reduce potential physical damage to internal precision components caused by operational errors, accidental contact, or external collisions. Therefore, this protective measure greatly enhances the overall protective effect of the antistatic bar assembly, ensuring its long-term operational stability and reliability.

[0028] Working principle and usage process of this invention: First, based on the actual width requirement of the film 103, the overall coverage length of the required antistatic device is calculated, and a corresponding number of auxiliary antistatic rods 203 are selected accordingly. Next, these auxiliary antistatic rods 203 are precisely aligned and spliced ​​at both ends of the main antistatic rod 202. Then, by rotating the knob 405, the bidirectional lead screw 402 is driven to rotate, thereby causing the two pairs of L-shaped plates 403 to move synchronously and in opposite directions, causing the limiting plate 404 to move towards the splicing point of the antistatic rods and clamp and fix them. After confirming that the locking block 408 has... Once fully embedded in the corresponding slot 407, the splicing and assembly steps are successfully completed. In addition, the surface of the limiting plate 404 is designed with anti-slip particles, which can effectively increase the friction between it and the splicing contact surfaces of the main antistatic bar 202 and the auxiliary antistatic bar 203, thereby further strengthening the stability of the fixation. Then, the card plate 302 with the guide plate 303 installed is smoothly inserted into the mounting base 301. Reliable fixation is achieved by the elastic force generated by the compression spring 308 and the clamping action of the clamping plate 307, thus completing the overall assembly process of the equipment. Secondly, after the overall assembly is completed, ionized dry air is introduced into the air passages inside the main antistatic bar 202 and the auxiliary antistatic bar 203. This dry air is evenly sprayed out through the pre-set first air hole 205 and second air hole 206, effectively neutralizing the static electricity of the film 103 passing over its surface. Under the guidance of the arc-shaped guide plate 303, the sprayed airflow is orderly dispersed and discharged to both sides of the film 103, avoiding interference with the stable transport of the film 103 due to airflow turbulence. During the continuous winding of the film 103, the static... The static elimination operation is also carried out simultaneously. The first air hole 205 adopts a sparse arrangement in the middle and dense arrangement on both sides. This design can well adapt to the characteristic that the edge area of ​​the film 103 is more prone to static electricity accumulation due to friction during the winding process. This provides a stronger air blowing static electricity discharge effect at the edge area where the amount of static electricity is greater. Combined with the simultaneous operation of the second air hole 206, the uniformity of the overall static electricity elimination is significantly improved. At the same time, the arc-shaped guide plate 303 can smoothly guide the ejected airflow to both sides to ensure a more uniform and consistent airflow distribution. Finally, after the winding of the film 103 is completed, the gas supply to the air passage inside the antistatic bar is stopped. At this time, the protective plate 304 is pulled downward by pulling the magnetic strip 305, so that the two magnetic strips 305 attract each other and fit tightly together, thereby splicing the protective plate 304 into a complete arc-shaped protective cover. Then, the two magnetic plates 306 are respectively fixed to the sealing plates 204 on the side of the two auxiliary antistatic bars 203 by magnetic attraction, thereby sealing the inside of the arc-shaped protective cover, completely protecting the main antistatic bar 202 and the two auxiliary antistatic bars 203. This effectively avoids the accumulation of external dust or possible accidental bumps and damage during the equipment's idle period, and significantly improves the protection effect of key antistatic components such as the main antistatic bar 202 and the auxiliary antistatic bars 203.
