Description

Technical Field

[0001] The utility model belongs to the technical field of plastic film drum fixing, and more specifically, relates to a plastic film drum fixing device. Background Art

[0002] Plastic film drums are usually cylindrical in shape, with a structure including an inner tube and an outer sleeve, and a smooth surface. They are commonly used for packaging, transporting, and unrolling plastic films. During the production process, the film is evenly wound around the drum, facilitating subsequent use. Plastic films are usually wound onto drums during production. This winding helps store and transport the film in a convenient form, preventing the film from being damaged or contaminated. In a plastic bag production line, the film is pulled from a large reel and made into plastic bags through various processing equipment (such as heat sealers). The film drum provides a continuous supply of raw materials for the production line, ensuring a smooth and efficient production process. The design and structure of the drum can help keep the film flat, avoiding wrinkles or curls during production, thus ensuring the quality and appearance of the final plastic bags. Using drums can improve production efficiency because the film is continuously supplied and processed during production, reducing manual intervention and downtime. The film wound on the drum is easy to operate and handle. When it is necessary to replace the raw material, the operator can quickly replace the drum and keep the production line running.

[0003] When the existing plastic film drum is fixed and rotates with the rotating bracket, it is prone to thread slipping. Summary of the Utility Model

[0004] In view of this, the utility model provides a plastic film drum fixing device, which can solve the problem of thread slipping when the existing plastic film drum rotates with the rotating bracket after being fixed.

[0005] The utility model is implemented as follows:

[0006] The utility model provides a plastic film drum fixing device, which includes a U-shaped part, a clamping plate, and a fixing component. The U-shaped part is arranged on both sides of the plastic film drum and is used to clamp the plastic film drum on the rotating bracket; the clamping plate is arranged at one side of the U-shaped part and is used to fix the two sides of the U-shaped part and the rotating bracket through extrusion force; the fixing component is arranged at both sides of the plastic film drum and is used to further fixedly connect the plastic film drum and the rotating bracket to prevent the plastic film drum from thread slipping during rotation.

[0007] Based on the above technical solution, the plastic film drum fixing device of the utility model can be further improved as follows:

[0008] Among them, the rotating bracket is provided with empty slots at positions for fixing both sides of the plastic film roller, and the diameter of the empty slots is larger than the diameters of both sides of the plastic film roller.

[0009] Furthermore, the diameters of both sides of the plastic film roller are smaller than the diameter of the position where the plastic film is wound inside it.

[0010] Furthermore, the bending direction of the U-shaped part faces the direction of the plastic film roller; a groove matching the U-shaped part is provided on one side of the rotating bracket.

[0011] Furthermore, clamping protrusions are provided at the position where the U-shaped part clamps the outer wall of the rotating bracket, and grooves are provided at the corresponding positions of the rotating bracket.

[0012] Furthermore, the clamping plate includes an arc-shaped plate and a spring, and the arc-shaped plate is clamped inside the empty slot of the rotating bracket through the spring.

[0013] Furthermore, the radian of the arc-shaped plate is the same as the inner radian of the empty slot of the rotating bracket.

[0014] Furthermore, the fixing component is of a sleeve structure, threads are provided at the position where the outer wall of the plastic film roller is connected to the rotating bracket, and matching threads are provided on the inner wall of the fixing component, for fixing the fixing component at the connection position of the plastic film roller and the rotating bracket by rotation.

[0015] Furthermore, the thickness of the thread is 5 mm.

[0016] Furthermore, the plastic film roller rotates following the rotating bracket.

[0017] Compared with the prior art, the beneficial effects of a plastic film roller fixing device provided by the present utility model are:

[0018] U-shaped part: This component is located on both sides of the plastic film roller, forming a U-shaped clamping structure. The bending direction of the U-shaped part faces the roller, which helps for tight clamping, enabling the roller to be stably installed on the rotating bracket. A clamping plate is provided on one side of the U-shaped part, for fixing the connection between the U-shaped part and the rotating bracket through extrusion force, preventing the roller from sliding during use.

[0019] Clamping plate: The clamping plate includes an arc-shaped plate and a spring. The radian of the arc-shaped plate is the same as the inner radian of the empty slot of the rotating bracket, enabling the clamping plate to precisely fit the empty slot of the bracket. The spring presses the arc-shaped plate tightly inside the empty slot of the rotating bracket, ensuring uniform and stable clamping force. This design improves the clamping effect of the overall fixing device and prevents any loosening of the roller.

[0020] Fixing Component: The fixing component is in the shape of a sleeve with threads on its outer wall, which match the threads at the connection between the plastic film roller and the rotating bracket. The fixing component is fixed at the connection position by rotation to further ensure the stability of the roller. The thickness of the thread is 5 mm, providing sufficient fastening force to prevent the roller from slipping or loosening during rotation. Description of the Drawings

[0029] Further, in the above technical solution, the bending direction of the U-shaped part 10 faces the direction of the plastic film roller; a groove matching the U-shaped part 10 is provided on one side of the rotating bracket.

[0030] Further, in the above technical solution, clamping protrusions are provided at the position where the U-shaped part 10 is clamped on the outer wall of the rotating bracket, and grooves are provided at the corresponding positions of the rotating bracket.

The clamping plate and spring mechanism further ensure the firm connection between the U-shaped part and the bracket without loosening by applying uniform pressure. Finally, the thread design of the fixing component applies additional fastening force by rotation, thus completely locking the roller on the bracket and preventing any sliding or instability.

[0037] Specifically, the principle of the present utility model is as follows: When in use, align the U-shaped part with both sides of the plastic film roller, ensure that its bent part faces the roller, and snap it into the groove of the rotating bracket. Place the clamping plate on one side of the U-shaped part, so that the arc-shaped plate is butted against the empty groove of the rotating bracket. The spring will automatically apply a clamping force to ensure that the clamping plate is tightly attached to the rotating bracket. Align the thread of the fixing component with the thread at the connection of the roller and the bracket, and rotate the fixing component clockwise until it is tightened in place. This step ensures that the roller is stably fixed on the rotating bracket. Ensure that all components are tightened in place without loosening. Gently shake the roller to check its stability and confirm that the device is working properly.
