Description

Technical Field

[0001] This utility model relates to the field of membrane material production technology, specifically to an anti-adhesion device for capacitor film production. Background Technology

[0002] In the production of capacitor films, a continuous film-feeding process is typically used, which involves stacking and molding double or multiple layers of film material, followed by cooling and shaping. These films exhibit strong adhesion after high-temperature extrusion. If they are not separated and cooled effectively in a timely manner, they are prone to sticking together during subsequent winding or transport, leading to wrinkles, tears, or performance degradation, severely impacting the consistency and yield of capacitor products.

[0003] In existing technologies, fixed guide rods or air-cooling devices are often used for membrane material separation and surface cooling. However, fixed guide structures often deviate or fail under high-speed membrane material movement due to adjustment lag and uneven membrane tension changes. Furthermore, air-cooling methods have low cooling efficiency and uneven temperature drop, making it difficult to meet the requirements of modern membrane material processes that demand high efficiency and high consistency.

[0004] In addition, existing separation structures are mostly single static components, lacking the ability to dynamically adjust and flexibly respond to the movement of membrane materials. This can easily lead to premature adhesion and entanglement of membrane materials on one side, increasing the frequency of manual intervention and resulting in poor process stability.

[0005] Therefore, designing an anti-adhesion device with automatic adjustment capabilities, dynamic separation functions, and active cooling methods has become a key technical issue for improving the production efficiency and quality control level of capacitor films. Utility Model Content

[0006] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0007] Therefore, the technical solution adopted by this utility model is as follows: an anti-adhesion device for capacitor film production, comprising a roller seat, an angle adjustment assembly, a linear drive assembly, and a separation hammer fixedly installed inside the angle adjustment assembly. The specific structure is as follows:

[0008] In a preferred embodiment, the angle adjustment assembly includes a sliding guide rod, a worm gear motor, and a sliding sleeve, the sliding sleeve being slidably fitted onto the inner side of the sliding guide rod. A separating hammer is fixedly connected to one end of the sliding sleeve; worm gear slip rings are fixedly installed at both ends of the sliding guide rod, the worm gear slip rings being rotatably mounted on the surface of the roller seat, the worm gear motor being fixed to the surface of the roller seat and driving the sliding guide rod to perform deflection motion; sliding tooth rings are fixedly installed on both sides of the sliding sleeve, and the inner side of the sliding guide rod is provided with a sliding groove that matches the sliding tooth ring; several permanent magnets are also fixedly installed on the inner side of the sliding sleeve.

[0009] Specifically, the deflection angle of the sliding guide rod is controlled by a worm gear motor, thereby adjusting the overall angle of the sliding assembly and the separation hammer. This facilitates timely correction of the separation position when the membrane material deviates from its running direction, thus improving the stability of membrane material transmission.

[0010] In a preferred embodiment, the linear drive assembly includes a main rod and a sliding sleeve fitted onto the surface of the main rod. A plurality of linearly arranged magnetic yokes are embedded and mounted on the inner side of the main rod, and excitation coils are wound around the surfaces of the magnetic yokes. The sliding sleeve housing is fixedly connected to the sliding sleeve assembly and is used to drive the sliding sleeve assembly to reciprocate linearly along the direction of the main rod.

[0011] Specifically, an alternating current is passed through the excitation coil to form an alternating magnetic field that acts on the permanent magnet in the sliding assembly, thereby achieving synchronous linear drive of the sliding assembly and the separation hammer, thus realizing continuous separation and tension release of the membrane material.

[0012] In a preferred example, the surface of the roller seat is provided with a plurality of guide rollers for guiding the movement of the capacitor film; the angle adjustment assembly, the linear drive assembly and the separation hammer are all arranged parallel to the guide rollers.

[0013] Specifically, this ensures that the movement trajectory of the membrane material is consistent with the guiding structure, preventing lateral deviation and uneven tension of the membrane material during operation, and improving overall transmission stability.

[0014] In a preferred example, the sliding guide rod has an arc-shaped tubular structure, the sliding sleeve is slidably sleeved on the inner side of the sliding guide rod, the separating hammer is pulled by the sliding sleeve, the top of the sliding guide rod outputs a capacitor film on one side, and the lower capacitor film is led downward along the guide roller.

[0015] Specifically, by setting up a curved guide structure to form an upper and lower separation trajectory, non-contact three-dimensional diversion of membrane materials is achieved, effectively preventing membrane materials from overlapping and tangling.

[0016] In a preferred example, the separating hammer is spindle-shaped with its thickness gradually decreasing on both sides of the centerline, and its thickness further decreases at the end away from the angle adjustment component, so that the separating hammer can achieve synchronous reciprocating motion as the membrane material passes through its surface.

[0017] Specifically, the overall shovel-shaped structure of the separating hammer allows it to be inserted into the membrane interlayer for efficient peeling, and the reciprocating sliding motion further enhances the dynamic desorption efficiency and strengthens the anti-adhesion effect.

[0018] In a preferred embodiment, the surface of the separating hammer is provided with a liquid inlet pipe, and one side of the separating hammer is provided with a plurality of spray holes communicating with the liquid inlet pipe for spraying out cooling water.

[0019] Specifically, precise water spraying cooling is implemented before the thermoplastic form of the membrane material is fully formed, which causes the membrane material temperature to drop rapidly and the surface to harden, preventing adhesion formation and effectively improving the separation cleanliness and process yield of the membrane material.

[0020] In a preferred example, the surface of the sliding sleeve is arc-shaped and smooth, and the sliding sleeve material is a polytetrafluoroethylene component.

[0021] Specifically, polytetrafluoroethylene has an extremely low coefficient of friction and excellent non-adhesive properties, which effectively reduces the adhesion resistance and frictional heat generation of the membrane material during the sliding process, further ensuring the surface quality and transmission stability of the membrane material.

[0022] In summary, this utility model, by introducing an angle adjustment component and a magnetic induction drive structure, enables the separation hammer to achieve synchronous, adjustable, and spray-linked separation of membrane materials. This effectively solves the problems of easy adhesion, inconvenient adjustment, and uneven cooling in traditional membrane material production, significantly improving membrane material forming efficiency and product consistency, and has high practical and promotional value.

[0023] The beneficial effects achieved by this utility model are as follows:

[0024] 1. In this utility model, by setting a worm gear motor to drive the sliding guide rod to adjust the angle in the angle adjustment component, and combining the linkage between the sliding kit and the separation hammer, the upper and lower film materials can be effectively separated during the transmission process, which effectively prevents the increase in scrap rate caused by adhesion in capacitor film production and improves the stability and yield of the film forming process.

[0025] 2. In this utility model, the separation hammer structure adopts a hollow liquid spraying design, and uses a sliding guide rail and a linear drive component to achieve reciprocating motion. While separating the membrane material, a cooling spray is applied to its surface, which allows the membrane material to harden and solidify quickly. This further reduces the risk of adhesion caused by thermal softening of the membrane material, and significantly improves the membrane material separation effect and process efficiency.

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0037] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0038] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing an anti-adhesion device for capacitor film production.

[0039] Combination Figures 1-5 As shown, the present invention provides an anti-adhesion device for capacitor film production, which includes: a roller seat 100, an angle adjustment component 200, a linear drive component 300, and a separation hammer 400 fixedly sleeved inside the angle adjustment component 200.

[0040] Roller seat 100 is used to support the entire device and set guide rollers for vertical guidance and transmission of the membrane material; angle adjustment component 200 is used to adjust the angle and correct the position of the separation hammer; linear drive component 300 is used to drive the separation hammer to perform axial reciprocating motion; separation hammer 400 is used to perform layer separation, guidance and cooling treatment during the operation of the membrane material.

[0041] In this embodiment, the angle adjustment assembly 200 consists of a sliding guide rod 210, a worm gear motor 220, and a sliding sleeve 230 fitted thereon. One end of the sliding sleeve 230 is fixedly connected to the separating hammer 400. Worm gear slip rings 211 are fitted at both ends of the sliding guide rod 210. These worm gear slip rings 211 are rotatably mounted on the surface of the roller seat 100 and are driven by the worm gear motor 220 to deflect the sliding guide rod 210. Sliding tooth rings 231 are fixed on both sides of the sliding sleeve 230, engaging with the sliding grooves on the sliding guide rod 210. A permanent magnet 232 is installed inside the sliding sleeve 230. The linear drive assembly 300 consists of a main rod 310 and its fitted sliding sleeve 320. The main rod 310 has several magnetic yokes 311 inside and an excitation coil 312 wound around it. The sliding sleeve 320 is connected to the sliding sleeve 230. The separating hammer 400 is fixedly connected to the front end of the assembly via the sliding sleeve 230, realizing the layered separation function.

[0042] In this embodiment, multiple guide rollers are provided on the surface of the roller seat 100 to ensure smooth conveying of the film material; the angle adjustment component 200, the linear drive component 300 and the separation hammer 400 are arranged in parallel with the guide rollers to ensure that the film material runs along a single plane and avoids deviation.

[0043] In this embodiment, the sliding guide rod 210 adopts an arc-shaped tubular structure, and the sliding sleeve 230 is slidably sleeved inside it. Through the cooperation structure of the sliding sleeve 230 and the sliding guide rod 210, the three-dimensional separation of the membrane material is realized: the upper membrane material is output from below the separation hammer 400, and the lower membrane material continues to be conveyed along the guide roller.

[0044] The separating hammer 400 adopts a spindle-shaped structure, narrowing towards both sides from the center line, and becoming more slender at the end away from the angle adjustment component 200. The sliding sleeve 230 pulls the separating hammer to perform axial reciprocating motion along the main rod 310, and actively achieves membrane peeling through the spindle geometry. Specifically, the separating hammer 400 has a spindle-shaped structure, with its thickness gradually decreasing towards both sides from the center line, and the thickness gradually thinning on the side of the separating hammer 400 away from the angle adjustment component 200.

[0045] In this embodiment, the separator 400 is provided with an inlet pipe 410 inside and a spray hole 420 on its outer wall. Water is supplied through the inlet pipe 410 into the spray hole 420 to cool the membrane material at specific points, which helps the hot membrane material to quickly set and harden.

[0046] In this embodiment, the magnetic yoke 311 on the surface of the main rod 310 is arranged around the excitation coil 312; when the excitation coil is energized with alternating current, it forms alternating magnetic attraction and repulsion under the action of the permanent magnet 232 in the sliding assembly 230, thereby realizing the reciprocating movement of the sliding assembly 230 and the separation hammer 400, effectively driving the separation operation.

[0047] In this embodiment, the outer surface of the sliding sleeve 320 has a smooth arc-shaped structure and is made of polytetrafluoroethylene (PTFE). This material has a low coefficient of friction and high non-adhesiveness, which can reduce the sliding resistance of moving parts.

[0048] Working principle and usage process of this utility model:

[0049] In normal operation of this utility model, the worm motor 220 first drives the sliding guide rod 210 to generate an angle deflection, which drives the sliding assembly 230 and its connected separation hammer 400 to adjust their posture, thereby realizing the change of the opposing angle between the entire angle adjustment assembly 200 and the linear drive assembly 300 to adapt to the separation requirements of different membrane material orientations.

[0050] Subsequently, during the continuous conveying of the membrane material, one layer of membrane material is conducted from the area below the separating hammer 400 and the sliding guide rod 210, while the other layer of membrane material is output from the area above the separating hammer 400 and the sliding guide rod 210. The two layers of membrane material are effectively separated as they pass over the surfaces of the separating hammer 400 and the sliding guide rod 210.

[0051] Meanwhile, the linear drive assembly 300 uses the changing magnetic field generated by the magnetic yoke 311 and the excitation coil 312 to traction the sliding kit 230 and its connected separation hammer 400 to reciprocate along the surface of the main rod 310, thereby achieving dynamic separation intervention and effectively overcoming the tendency of membrane material adhesion.

[0052] During the separation process, the surface of the separation hammer 400 is equipped with spray holes 420 for spraying cooling water onto the membrane material. This reduces the surface temperature of the membrane material, promoting its hardening and preventing adhesion caused by thermal softening, thereby ensuring the stability of the continuous production process and product quality of the capacitor film.
