Description

Technical Field

[0001] This utility model relates to the field of metallized thin film technology, specifically to a metallized thin film slitting device. Background Technology

[0002] Metallized films, as functional composite materials with a metal layer deposited on their surface, are widely used in capacitors, packaging materials, electronic devices, and other fields due to their excellent electrical and mechanical properties. During the production process, wide metallized films need to be slit into narrow films of specific widths according to actual requirements; therefore, the accuracy and stability of the slitting equipment directly affect product quality.

[0003] Current metallized film slitting devices are prone to lateral slippage during the film slitting process due to factors such as uneven tension and roller rotation deviation, resulting in uneven slitting edges and excessive width deviation. This is especially true for thin metallized films, where even a slight deviation can affect subsequent processing. Therefore, a metallized film slitting device is proposed to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a metallized thin film slitting device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a metallized film slitting device, including a base, a bracket fixedly connected to the top of the base, a roller body provided on the bracket, and a positioning mechanism provided on the bracket; The positioning mechanism includes an electromagnet and a clamping plate, both of which are sleeved on the roller body, and a permanent magnet is provided on the clamping plate.

[0006] Preferably, the positioning mechanism further includes a drive motor and a bidirectional threaded rod. The drive motor is fixedly installed on one side of the bracket, one end of the bidirectional threaded rod is fixedly connected to the output end of the drive motor, and the other end of the bidirectional threaded rod rotatably passes through the bracket.

[0007] Preferably, a connecting rod is threaded onto the bidirectional threaded rod, and mounting discs are fixedly connected to both ends of the connecting rod. The mounting discs are fitted onto the roller body, and the electromagnet is mounted on the mounting discs.

[0008] Preferably, there are two connecting rods, which are symmetrically arranged on the bidirectional threaded rod.

[0009] Preferably, the support is provided with a cleaning mechanism, which includes a frame, a movable plate and an antistatic scraper. The frame is installed on the top of the support, and the top of the inner wall of the frame is connected to the top of the movable plate by a spring. The antistatic scraper is installed on the bottom of the movable plate.

[0010] Preferably, a base frame is fixedly connected to the top of the base, a cylinder is fixedly installed on the top of the inner wall of the base frame, a mounting plate is connected to the bottom of the output end of the cylinder, and a cutter is installed on the mounting plate.

[0011] The present invention adopts the above technical solution, which can bring the following beneficial effects: This metallized film slitting device uses an electromagnet in the positioning mechanism to generate a repulsive force with a permanent magnet on a clamping plate, which pushes the clamping plate to stably hold the film on both sides. This effectively prevents the film from sliding laterally during the slitting process due to uneven tension or roller rotation deviation. By adjusting the current of the electromagnet, the repulsive force between the electromagnet and the permanent magnet can be precisely controlled, thereby flexibly adjusting the clamping force of the clamping plate on the film. This avoids damage to the film edges due to excessive force and prevents positioning failure due to insufficient force.

[0012] This metallized film slitting device features a clamping plate that rotates synchronously with the film roll while holding the film, preventing edge wear caused by relative displacement between the two. The bidirectional threaded rod and symmetrically arranged connecting rods drive the mounting plate to move smoothly, further improving the operational stability of the positioning mechanism and reducing mechanical damage during the slitting process.

[0013] 3. In this metallized film slitting device, when the antistatic scraper of the impurity removal mechanism comes into contact with the film roll, it can simultaneously remove surface impurities and static electricity generated by friction. Combined with the elasticity of the spring, it ensures that the scraper is always in close contact with the film, which solves the problems of impurity adsorption and static electricity causing loose winding or interlayer adhesion, and ensures the flatness of the film roll after slitting and its subsequent performance.

[0016] 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.

[0017] Please see Figure 1-4 A metallized film slitting device includes a base 1, a bottom frame 7 fixedly connected to the top of the base 1, a guide roller installed inside the bottom frame 7 for guiding the metallized film, a cylinder 8 fixedly installed on the top of the inner wall of the bottom frame 7, a mounting plate 9 connected to the bottom of the output end of the cylinder 8, a cutter 10 installed on the mounting plate 9, a bracket 2 fixedly connected to the top of the base 1, two rollers 3 are provided on the bracket 2, a winding motor 4 is installed on the bracket 2, the output end of the winding motor 4 is fixedly connected to the right roller 3, and the left roller 3 is installed on the bracket 2 through a mounting seat for easy disassembly and assembly. The two rollers 3 are respectively used to place the metallized film roll and to wind up the slitting metallized film. A positioning mechanism 5 is provided on the bracket 2. The positioning mechanism 5 includes an electromagnet 55 and a clamping plate 56, both of which are sleeved on the roller body 3. A permanent magnet 57 is provided on the clamping plate 56. The positioning mechanism 5 also includes a drive motor 51 and a bidirectional threaded rod 52. The drive motor 51 is fixedly installed on one side of the bracket 2. One end of the bidirectional threaded rod 52 is fixedly connected to the output end of the drive motor 51, and the other end of the bidirectional threaded rod 52 rotatably passes through the bracket 2. A connecting rod 53 is threaded on the bidirectional threaded rod 52. Both ends of the connecting rod 53 are fixedly connected to a mounting plate 54, which is sleeved on the roller body 3. The electromagnet 55 is installed on the mounting plate 54. There are two connecting rods 53, which are symmetrically arranged on the bidirectional threaded rod 52.

[0018] The support 2 is equipped with a cleaning mechanism 6, which includes a frame 61, a movable plate 63 and an antistatic scraper 64. The frame 61 is installed on the top of the support 2, and the top of the inner wall of the frame 61 is connected to the top of the movable plate 63 by a spring 62. The antistatic scraper 64 is installed on the bottom of the movable plate 63.

[0019] Working principle: The metallized film roll is placed on the left roller 3, and the metallized film is passed through the guide roller and fixed on the right roller 3. The drive motor 51 is started to drive the bidirectional threaded rod 52 to rotate, thereby driving the connecting rod 53 to move. The movement of the connecting rod 53 will drive the mounting plate 54 to move. At the same time, the electromagnet 55 is energized, and the electromagnet 55 generates a repulsive force on the permanent magnet 57. This repulsive force pushes the clamping plate 56 to clamp the two sides of the metallized film, preventing the metallized film from shifting and affecting the slitting effect. The magnitude of the repulsive force between the electromagnet 55 and the permanent magnet 57 can be adjusted by adjusting the current of the electromagnet 55, thereby adjusting the clamping force. The cylinder 8 is started to drive the cutter 10 on the mounting plate 9 to descend, and the winding motor 4 is started to drive the right roller 3 to rotate, thereby slitting and winding the metallized film. At this time, the clamping force applied by the clamping plate 56 to the two sides of the metallized film roll will cause the clamping plate 56 and the metallized film roll to rotate synchronously, avoiding relative displacement that would cause wear on the metallized film roll.

[0020] When the slit metallized film roll is wound up by the right-side roller 3, it comes into contact with the antistatic scraper 64. The antistatic scraper 64 removes impurities and static electricity from the metallized film, preventing impurities and static electricity from causing the slit metallized film roll to be not tightly wound, which would affect subsequent use. At the same time, the spring 62 allows the antistatic scraper 64 to contact the bottom of the metallized film roll, improving the stability of impurity removal and static electricity removal.

The above description is only a preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model. All components not explicitly stated in this embodiment can be implemented using existing technology.
