Description

Technical Field

[0001] This utility model relates to the field of PE film processing technology, specifically a PE film traction device. Background Technology

[0002] In the production, processing, or packaging of PE film (polyethylene film), the film material often needs to be traction and conveyed for subsequent cutting, winding, or lamination operations. Existing PE film traction devices are usually relatively simple in structure, mainly relying on guide rollers and traction rollers to move the film material. However, in actual use, due to the relatively soft texture of the film material, it is prone to deviation, slippage, or wrinkling during traction, affecting product quality. In addition, traditional devices lack effective pressing mechanisms and adjustable positioning structures, making it difficult to adapt to the traction requirements of PE films of different thicknesses. They also have poor operational flexibility, unstable tension control of the film material during traction, and low automation, which affects production efficiency and product quality stability.

A fixing plate is fixedly connected to the bottom of the support rod. An adjusting bolt is threadedly connected to the middle of the fixing plate. A positioning plate is rotatably connected to the bottom of the adjusting bolt. The positioning plate is disposed on the top of the placement base.

[0006] Preferably, the number of limiting members is two, and the two limiting members are symmetrically arranged. The two symmetrically arranged limiting members can ensure that the placement seat is subjected to uniform force during movement, prevent it from tilting or shaking, thereby improving the stability and positioning accuracy of the traction process.

Guide rods are fixedly connected to both sides of the motor surface, and support members are slidably connected to the surface of the guide rods. The support members are fixedly connected to both sides of the placement base. The motor drives the threaded rod to rotate, causing the placement base to move horizontally. The guide rods cooperate with the support members to provide sliding guide support for the placement base, preventing it from rotating or deviating during movement, and ensuring the linearity and stability of the traction action.

[0008] Preferably, the clamping mechanism includes a mounting base, which is fixedly connected to the top left side of the support base, the threaded rod is rotatably connected to the right side of the mounting base, and the guide rod is fixedly connected to the right side of the mounting base.

The vertical plate is fixedly connected to the top of the support base. A spring is sleeved on the surface of the vertical rod, and the spring is disposed between the mounting block and the vertical plate. The spring provides a downward elastic force to the mounting block, so that the second guide roller automatically presses against the first guide roller. The vertical rod plays a guiding role to ensure that the mounting block moves vertically without deviation, thereby achieving a stable elastic pressing force to adapt to PE films of different thicknesses.

[0011] Preferably, fixing blocks are fixedly connected to both sides of the surface of the mounting block, and a fixing rod is slidably connected inside the fixing block. The fixing rod is fixedly connected to the surface of the vertical plate, and a connector is fixedly connected to the surface of the vertical rod.

[0026] Furthermore, two limiting members 26 are provided, and the two limiting members 26 are symmetrically arranged. The symmetrical arrangement of the two limiting members 26 can ensure that the placement seat 29 is subjected to uniform force during movement, preventing it from tilting or shaking, thereby improving the stability and positioning accuracy of the traction process.

Guide rods 22 are fixedly connected to both sides of the surface of the motor 21. Support members 203 are slidably connected to the surface of the guide rods 22. The support members 203 are fixedly connected to both sides of the placement base 29. The motor 21 drives the threaded rod 202 to rotate, causing the placement base 29 to move horizontally. The guide rods 22 cooperate with the support members 203 to provide sliding guide support for the placement base 29, preventing it from rotating or deviating during movement and ensuring the linearity and stability of the traction action.

[0028] Example 2:

[0029] See Figure 4Furthermore, based on Embodiment 1, the clamping mechanism 3 further includes a mounting base 34, which is fixedly connected to the top left side of the support base 1. The threaded rod 202 is rotatably connected to the right side of the mounting base 34, and the guide rod 22 is fixedly connected to the right side of the mounting base 34. The mounting base 34 serves as the common support foundation for the clamping mechanism 3 and the driving mechanism, playing a role in structural connection and positioning. The connection method between the threaded rod 202 and the guide rod 22 and the mounting base 34 facilitates overall assembly and alignment, improving the operational reliability of the mechanism.

[0030] Furthermore, grooves are provided on both sides of the top of the mounting base 34, and mounting blocks 301 are provided in both grooves. A second guide roller 36 is rotatably connected between the two mounting blocks 301. A first guide roller 35 is provided at the bottom of the second guide roller 36. The first guide roller 35 is rotatably connected to the mounting base 34. The first guide roller 35 and the second guide roller 36 form a counter-rolling structure to guide the PE film into the traction area. The grooves and mounting blocks 301 allow the second guide roller 36 to move up and down, which facilitates the film insertion operation and achieves elastic compression of the film material during operation.

The spring 38 is located between the mounting block 301 and the vertical plate 39. The spring 38 provides a downward elastic force to the mounting block 301, so that the second guide roller 36 automatically presses against the first guide roller 35.

The fixing blocks 32 and fixing rods 33 cooperate to further restrict the movement direction of the mounting block 301, prevent it from swaying or rotating back and forth under the force of the spring 38, and enhance the structural rigidity and smooth operation of the pressing mechanism 3.

[0033] In actual operation, when this device is used, firstly, by pulling the mounting block 301 upward, the second guide roller 36 moves upward. Then, by passing the PE film between the first guide roller 35 and the second guide roller 36 and loosening the mounting block 301, the first guide roller 35 can be reset under the elastic potential energy of the spring 38. At this time, the first guide roller and the second guide roller 36 can achieve the purpose of pressing the PE film, avoiding the phenomenon of wrinkles in the PE film during the traction process.

[0034] When the right end of the PE film is at the bottom of the positioning plate 28, the adjusting bolt 27 can be rotated to drive the positioning plate 28 to move downward, so that the positioning plate 28 presses the right end of the PE film. Then, by starting the motor 21, the motor 21 can drive the threaded rod 202 to rotate. During the rotation of the threaded rod 202, the placement seat 29 can be driven to move to the right to achieve the purpose of automatic traction of the PE film.
