Description

Technical Field

[0001] This utility model relates to the technical field of membrane product processing equipment, specifically to an antistatic device for membrane product processing. Background Technology

[0002] During membrane material processing, the friction between the high-speed moving membrane material and equipment components generates a large amount of static electricity. This static electricity not only attracts dust, affecting product cleanliness, but may also trigger electrical sparks, posing a threat to production safety and product quality. Therefore, effectively eliminating static electricity is a crucial step in the membrane processing field.

[0003] Currently, ion bars are widely used in the industry for static electricity elimination. However, the installation and adjustment methods of ion bars in existing equipment have significant shortcomings. Most devices only support simple height adjustment, or are even completely fixed, and cannot adjust the vertical spacing according to membrane thickness, tension, or process requirements. More importantly, existing technology lacks a convenient and reliable angle adjustment mechanism, and the blowing direction of the ion bar cannot be optimized for the membrane surface, resulting in uneven ion coverage efficiency and affecting the overall static elimination effect. At the same time, common adjustment mechanisms often lack effective locking functions, and are prone to displacement under equipment vibration, making it difficult to maintain a stable process state.

[0004] Therefore, there is an urgent need to develop an antistatic device for membrane product processing to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide an antistatic device for membrane product processing, which solves the problems of inconvenient adjustment and limited guiding function of ion air bars in the prior art, and realizes flexible adjustment of height and angle.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An antistatic device for membrane product processing includes a mounting frame. The mounting frame is slidably connected to two static elimination units via a lifting mechanism. The two static elimination units are arranged in parallel vertically, and a membrane is inserted between the two static elimination units. Each static elimination unit includes a pair of sliding seats arranged symmetrically on the left and right sides. The pair of sliding seats is rotatably connected to a horizontally arranged ion air bar via a rotating mechanism. Along the transmission path of the thin film, a set of guide wheels is provided on the mounting frame at the front and rear positions corresponding to the ion air bar; a grounding terminal is provided on one side of the bottom of the mounting frame.

[0008] Preferably, the limiting component further includes a fixing post and two pressing members; the fixing post is disposed in the sliding seat, and each end of the fixing post is fixedly connected to a locking block by a spring; the two pressing members are respectively fixed on the two locking blocks at the ends away from the fixing post, and the side of the pressing member near the fixing post is further away from the mounting bracket in the horizontal direction than the side of the protrusion near the sliding seat; the minimum distance between the outer surfaces of the two locking blocks is less than the gap between the two rows of protrusions.

[0009] Preferably, the rotating mechanism includes a mounting plate, which is detachably connected to the ion bar; one end of the mounting plate is fixedly connected to a geared disc via a first connecting shaft, and the other end is fixedly connected to a flat disc via a second connecting shaft.

Detailed Implementation

[0016] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0017] Example 1 like Figures 1 to 6 As shown, this embodiment discloses an antistatic device for membrane product processing, including a mounting frame 10. The mounting frame 10 is slidably connected to two vertically parallel antistatic units via a lifting mechanism, with the membrane passing between the two antistatic units. Each antistatic unit includes a pair of symmetrically arranged sliding seats 20, which are rotatably connected to a horizontally arranged ionizer 40 via a rotating mechanism. Along the membrane's transmission path, a set of guide wheels 50 are provided on the mounting frame 10 at positions corresponding to the front and rear positions of the ionizer 40. A grounding terminal 16 is provided on one side of the bottom of the mounting frame 10.

[0018] The lifting mechanism includes a sliding assembly. The sliding assembly includes slide rails 14 on both sides of the mounting frame 10 and slide grooves 21 on the sliding seat 20. The slide rails 14 and slide grooves 21 are slidably engaged, allowing the sliding seat 20 to move vertically along the mounting frame 10.

[0019] The lifting mechanism also includes a limiting assembly for locking the sliding seat 20 at the desired height. The limiting assembly includes a locking plate 11 on both sides of the mounting bracket 10 and a block assembly on the sliding seat 20. The locking plate 11 has two symmetrically arranged rows of protrusions, each row of protrusions including multiple protrusions 12 spaced apart in the vertical direction, and the gap between two adjacent protrusions 12 forms a slot 13. The block assembly includes two symmetrically arranged blocks 22, and the width of the blocks 22 is adapted to the width of the slot 13.

[0020] The limiting assembly also includes a fixed post 24 and two pressing members 23. The fixed post 24 is located inside the sliding seat 20, and each end of the fixed post 24 is fixedly connected to a locking block 22 by a spring 25. The two pressing members 23 are respectively fixed to the ends of the two locking blocks 22 away from the fixed post 24, and the side of the pressing member 23 near the fixed post 24 is further away from the mounting bracket 10 in the horizontal direction than the side of the protrusion 12 near the sliding seat 20. The minimum distance between the outer surfaces of the two locking blocks 22 is less than the gap between the two rows of protrusions.

[0021] When height adjustment is required, pressing the pressing members 23 located on both sides of the sliding seat 20 inwards will cause the two locking blocks 22 to retract towards the center against the force of the springs 25, thereby disengaging them from the current locking slots 13. At this time, the two locking blocks 22 are located in the gap between the two rows of protrusions, and the sliding seat 20 can move freely up and down. After sliding to the target height, releasing the pressing members 23 will cause the two locking blocks 22 to engage with the corresponding heights of the locking slots 13 of the two rows of protrusions under the reset action of the two springs 25, thus reliably locking the sliding seat 20 in the vertical direction.

[0022] A rotating mechanism is used to adjust and lock the angle of the ion bar 40. The rotating mechanism includes a mounting plate 31 for mounting the ion bar 40. One end of the mounting plate 31 is fixedly connected to a geared disc 33 via a first connecting shaft 32, and the other end is fixedly connected to a flat disc 36 via a second connecting shaft 35. The thickness of the flat disc 36 is less than the thickness of the geared disc 33. The side of the geared disc 33 facing the mounting plate 31 has a ring of first serrations 34. The sliding seat 20 has a mounting cavity. The top of the mounting cavity has a shaft hole for the first connecting shaft 32 or the second connecting shaft 35 to pass through, and the top of the mounting cavity also has a ring of second serrations 27 that can mesh with the first serrations 34. A wave spring 26 is fixedly connected to the bottom of the mounting cavity, and the free end of the wave spring 26 abuts against the geared disc 33.

[0023] When the angle of the ion bar 40 needs to be adjusted, the mounting plate 31 is pulled axially along the side where the toothed disc 33 is located, causing the mounting plate 31, toothed disc 33, and flat disc 36 to move as a whole towards the sliding seat 20 on that side. This action compresses the wave spring 26 on the side of the toothed disc 33 and disengages the first serration 34 on the toothed disc 33 from the second serration 27 at the top of the mounting cavity. Because the flat disc 36 is relatively thin, there is an axial gap between it and the wave spring 26 in the sliding seat 20 on the other side, providing space for the overall axial movement of the mounting plate 31. At this time, the mounting plate 31 and the ion bar 40 can be rotated to the target angle. After the angle adjustment is completed, the mounting plate 31 is released, the compressed wave spring 26 rebounds, pushing the toothed disc 33 to move in the opposite direction, causing the first serration 34 on it to re-engage with the second serration 27 at the top of the mounting cavity, thereby firmly locking the ion bar 40 at the new angle.

[0024] A guide wheel 50 positioned between the two electrostatic elimination units is mounted on the mounting frame 10 via a connecting rod 15. The guide wheel 50 has a circumferential V-shaped guide groove, the surface of which is covered with a conductive rubber layer. The edge of the membrane material can be embedded within the V-shaped guide groove for guidance and to prevent deviation, while the conductive rubber layer can also dissipate localized static charges from the membrane material edge.

[0025] The working process of this utility model is as follows: Adjust the height of the upper and lower electrostatic elimination units according to the membrane thickness and process requirements. Release the locking mechanism by pressing the pressing pieces 23 on both sides of the sliding seat 20, slide the sliding seat 20 up and down to the appropriate height, and then release to lock the height. Adjust the upper and lower ion air bars 40 to the optimal blowing angle by pulling and rotating them axially to optimize the coverage of the ion airflow on the upper and lower surfaces of the membrane. After adjustment, release the levers, and the rotation mechanism will automatically lock.

[0026] The device is installed in the production line, allowing the membrane material to be guided through the V-shaped groove of the feed-side guide wheel 50, pass through the action area between the upper and lower ion air bars 40, and finally exit through the V-shaped groove of the discharge-side guide wheel 50. The neutralized ions generated by the ion air bars 40 are blown by the airflow to the upper and lower surfaces of the membrane material, eliminating static charge. While guiding the membrane material, the conductive rubber layer of the guide wheel 50 helps to conduct away edge charges. The entire device is reliably grounded through the grounding terminal 16, forming a continuous conductive path with the metal components of the mounting frame 10, connecting rod 15, guide wheel 50, and ion air bars 40. This quickly conducts the residual static electricity on the membrane surface after neutralization by the ion air bars 40, as well as the edge charges conducted by the conductive rubber layer of the guide wheel 50, to the ground, preventing secondary accumulation of static electricity and ensuring the stability of the static elimination effect and production safety.

[0027] In summary, the electrostatic eliminator for membrane product processing provided in this embodiment integrates an independently adjustable and lockable height and angle adjustment mechanism into its electrostatic elimination unit. This allows for flexible adaptation to different working conditions and precise optimization of the working distance and blowing direction of the ion bar 40. The guide wheel 50 combines physical guidance with contact-type electrostatic conduction. Through the coordinated design of the grounding terminal 16 and the continuous conductive structure inside the device, a complete electrostatic neutralization and discharge path is constructed, effectively improving the adaptability and effectiveness of electrostatic elimination operations.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
