Description

Technical Field

[0001] This utility model relates to the field of heat shrink tubing production technology, specifically to a seamless heat shrink tubing pulling device. Background Technology

[0002] During the production of heat shrink tubing, the tubing needs to be wound up, but in subsequent processing steps such as cutting, it needs to be unwound. Both winding and unwinding require pulling the heat shrink tubing to facilitate the process. Currently, there is no suitable pulling equipment, which poses a challenge to this process and cannot meet production needs.

[0003] A search revealed that publication number CN217226668U discloses a heat shrink tubing pulling device, including a worktable with tubing guide frames on both sides above the worktable. The guide frames are equipped with lower and upper guide wheels. The lower guide wheel is connected to a pulley via a shaft. A drive motor is installed below the worktable, and a drive wheel is mounted on the output shaft of the drive motor. The drive wheel and the lower guide wheel are connected by a belt for transmission. In use, this heat shrink tubing pulling device utilizes the drive motor to provide driving force, combined with the clamping structure of the upper and lower guide wheels to clamp the heat shrink tubing, thus completing the pulling operation and facilitating the production of heat shrink tubing.

[0004] However, when using the above-mentioned device, the heat shrink tubing needs to be flattened to a certain extent in order to transfer the traction force to the heat shrink tubing. If the heat shrink tubing deforms too much when flattened, it will affect the flow of compressed gas inside the tubing, thus affecting the expansion process. If the heat shrink tubing deforms too little when flattened, the clamping force will be insufficient, which will easily cause slippage, resulting in unstable traction and poor practicality.

[0005] Therefore, a seamless heat shrink tubing pulling device needs to be designed to improve the above problems. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model designs a seamless heat shrink tubing pulling device. This heat shrink tubing pulling device aims to solve the technical problems of poor clamping stability of heat shrink tubing in existing pulling devices, which easily cause deformation of the heat shrink tubing and affect its use.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A seamless heat shrink tubing pulling device includes a support platform. A positioning frame is fixedly connected to one side of the top of the support platform. Arc-shaped grooves are formed on both sides of the top of the positioning frame. An adjusting frame is fixedly connected between the two sets of arc-shaped grooves at the top of the positioning frame. An adjusting groove is formed on both sides of the adjusting frame. A pair of guide slide rods are fixedly connected inside the adjusting frame. An adjusting screw is threaded to the top of the adjusting frame. A clamping frame is rotatably connected to the bottom end of the adjusting screw inside the adjusting frame. Clamping grooves are formed on both sides of the bottom of the clamping frame at positions corresponding to the arc-shaped grooves. An elastic telescopic strip is installed on both sides of the inner wall of each clamping groove. An arc-shaped clamping block is fixedly connected to the end of each elastic telescopic strip away from the clamping groove. A pair of guide blocks are fixedly connected to the top of the support platform. Two sets of traction components are rotatably connected between the two sets of guide blocks at the top of the support platform. A motor is installed below the traction components at the bottom of the support platform.

[0009] Preferably, a pair of guide wheels are rotatably connected to the bottom of the arc-shaped groove inside the positioning frame.

[0010] Preferably, the elastic telescopic bar is composed of a telescopic rod and a return spring, and the return spring is sleeved on the outer side of the telescopic rod.

[0011] Preferably, the clamping frame has a sliding hole at a position corresponding to the guide slide rod, and the clamping frame is slidably connected to the guide slide rod through the sliding hole.

[0012] Preferably, each of the two sets of guide blocks has an arc-shaped guide groove on one side, and the side of the two sets of arc-shaped guide grooves that are far apart is rotatably connected to two sets of guide wheels inside the guide block.

[0013] Preferably, the traction assembly consists of a connecting block, a second elastic telescopic strip, and a second arc-shaped clamping block. A set of second elastic telescopic strips is installed on each of the four sides of the connecting block. The second elastic telescopic strip has the same structure as the first elastic telescopic strip. The end of the second elastic telescopic strip away from the connecting block is fixedly connected to the second arc-shaped clamping block.

[0014] Preferably, the inner wall of the arc-shaped clamping block two is provided with a rubber anti-slip pad, and the outer side of the rubber anti-slip pad is provided with a number of anti-slip particles.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The adjusting screw is threadedly connected to the adjusting frame, pushing the clamping frame to descend. The clamping frame uses the elastic telescopic strip in the clamping groove to contract under force, which drives the arc-shaped clamping block and the arc-shaped groove on the top of the auxiliary positioning frame to clamp and position the heat shrink tubing, avoiding excessive pressure that could cause the heat shrink tubing to be squeezed and deformed, and improving the stability of the heat shrink tubing clamping.

[0017] 2. The left motor drives the left connecting block to rotate counterclockwise, and the right motor drives the right connecting block to rotate clockwise. The elastic telescopic strip 2 contracts under force, which drives the arc-shaped clamping block 2 to use the anti-slip particles on the rubber anti-slip pad to generate friction with the heat shrink tubing in the arc-shaped guide groove for pulling and conveying. The guide wheel 1 and guide wheel 2 improve the smoothness and stability of the heat shrink tubing pulling and conveying. Attached Figure Description

[0028] In this embodiment, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The bottom end of the adjusting screw 303 is rotatably connected to the clamping frame 4 inside the adjusting frame 3. Clamping grooves 401 are formed on both sides of the bottom of the clamping frame 4, corresponding to the arc-shaped groove 201. Elastic telescopic strips 402 are installed on both sides of the inner wall of the clamping grooves 401. Each elastic telescopic strip 402 consists of a telescopic rod 4021 and a return spring 4022. The return spring 4022 is sleeved on the outer side of the telescopic rod 4021. An arc-shaped clamping block 403 is fixedly connected to the end of the elastic telescopic strip 402 away from the clamping groove 401. The adjusting screw 303... The clamping frame 4 is threadedly connected to the adjusting frame 3, which pushes the clamping frame 4 to descend.

The clamping frame 4 is slidably connected to the guide slide rod 302 through the sliding hole 404, which improves the stability of the height adjustment of the clamping frame 4.

[0029] In this embodiment, please refer to Figure 1 and Figure 2 A pair of guide blocks 5 are fixedly connected to the top of the support platform 1. Each of the two sets of guide blocks 5 has an arc-shaped guide groove 501 on one side. The guide blocks 5 use the arc-shaped guide groove 501 to guide the heat shrink tubing.

The clamping frame 4 is slidably connected to the guide slide rod 302 through the sliding hole 404, improving the stability of the height adjustment of the clamping frame 4. The clamping frame 4 utilizes the elastic telescopic strip 402 in the clamping groove 401 to contract under force, driving the arc-shaped clamping block 403 to assist the positioning frame 2 in clamping and positioning the heat shrink tubing in the arc-shaped groove 201 at the top, avoiding excessive pressure that could cause heat shrinkage. The heat shrink tubing is squeezed and deformed to improve the stability of the heat shrink tubing clamping. The left motor 7 drives the left connecting block 601 to rotate counterclockwise, and the right motor 7 drives the right connecting block 601 to rotate clockwise. The elastic telescopic strip 602 is compressed under force, which drives the arc-shaped clamping block 603 to use the anti-slip particles on the rubber anti-slip pad 6031 to generate friction with the heat shrink tubing in the arc-shaped guide groove 501 for pulling and conveying.
