Description

Technical Field

[0001] This utility model relates to the field of plastic film processing technology, and in particular to a high-performance PE core embossed pipe for plastic film. Background Technology

[0002] In the production and processing of plastic film, the core tube is an important component used for winding the plastic film, and its performance directly affects the winding quality, storage stability and subsequent ease of use of the plastic film.

[0003] Currently, most commonly used plastic film core tubes on the market are ordinary PE tubes with relatively smooth surfaces. When winding the plastic film, the friction between the film and the tube is low, easily leading to film slippage and misalignment, resulting in uneven winding and affecting product quality and production efficiency. Furthermore, ordinary PE tubes have limited structural strength and are prone to deformation or even breakage under high film winding tension, failing to meet the requirements of high-performance plastic film core tubes. Therefore, we propose a high-performance PE core embossed tube for plastic film to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a high-performance PE core embossed pipe for plastic film, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-performance PE core embossed pipe for plastic film includes a pipe body. A stabilizing frame is provided within the inner cavity of the pipe body. A recessed groove is formed on the outer side of the pipe body. Limiting plates are fitted on both the front and rear sides of the outer side of the pipe body. Limiting seats are fixedly installed on the front side of the front limiting plate and the rear side of the rear limiting plate. A bidirectional screw is rotatably connected to the left side of the top and bottom of the limiting seat's inner cavity. A worm gear is fixedly fitted in the middle of the outer side of the bidirectional screw. A worm adapted to the worm gear is rotatably connected to one side of the limiting seat's inner cavity. Moving blocks are screwed to the left and right sides of the outer side of the bidirectional screw. A connecting rod is fixedly installed on the right side of the moving block. A support block is fixedly installed on the right side of the connecting rod. Vertical rods are fixedly installed on both the left and right sides of one side of the support block. One side of the vertical rod passes through the limiting seat and is fixedly fitted with an arc-shaped clamp.

[0007] Preferably, the outer side of the stabilizing frame is fixedly connected to the inner wall of the tube, and there are two sets of stabilizing frames, which are symmetrically distributed front and back.

[0008] Preferably, the number of the recessed grooves is four sets, and they are distributed in a ring array.

[0009] Preferably, one side of the worm gear movably passes through the limiting seat and is fixedly connected to a handwheel, and one side of the arc-shaped clamp is in contact with the tube body.

[0010] Preferably, a limiting rod adapted to the support block is fixedly installed in the inner cavity of the limiting seat, and the outer side of the limiting rod slides in contact with the inside of the support block.

[0011] Preferably, the inside of the limiting plate is in sliding contact with the outside of the tube, and the outside of the vertical rod is in sliding contact with the inside of the limiting seat.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, rotating the handwheel forward drives the worm gear to rotate, which in turn drives the matching worm wheel to rotate. The worm wheel then drives the bidirectional lead screw to rotate, which in turn drives the screwed moving blocks to move away from each other. The moving blocks, through the connecting rod, drive the support blocks to move away from each other. The support blocks, through the vertical rod, drive the arc-shaped clamps to move away from each other, thus moving the arc-shaped clamps away from the tube body. Then, the limiting plate is moved, and the handwheel is reversed to reset the arc-shaped clamps and fix the limiting plate. This can limit the film and prevent the two ends of the film from shifting, further ensuring the stability of the film winding.

[0014] 2. In this utility model, the cooperation between the stabilizing frame and the recessed groove increases the friction between the tube and the plastic film, effectively solving the problems of slippage and misalignment during film winding and improving the winding efficiency of the plastic film.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-3 A high-performance PE core embossed pipe for plastic film includes a pipe body 1. A stabilizing frame 5 is provided in the inner cavity of the pipe body 1. A recessed groove 4 is provided on the outer side of the pipe body 1. Limiting plates 2 are fitted on both the front and rear sides of the outer side of the pipe body 1. Limiting seats 3 are fixedly installed on the front side of the front limiting plate 2 and the rear side of the rear limiting plate 2. A bidirectional screw 6 is rotatably connected to the left side of the top and bottom of the inner cavity of the limiting seat 3. A worm gear 12 is fixedly fitted in the middle of the outer side of the bidirectional screw 6. A worm 13 adapted to the worm gear 12 is rotatably connected to one side of the inner cavity of the limiting seat 3. Moving blocks 7 are screwed to the left and right sides of the outer side of the bidirectional screw 6. A connecting rod 8 is fixedly installed on the right side of the moving block 7. A support block 9 is fixedly installed on the right side of the connecting rod 8. Vertical rods 10 are fixedly installed on the left and right sides of one side of the support block 9. An arc-shaped clamp 15 is fixedly installed through the limiting seat 3 on one side of the vertical rod 10.

[0021] In this embodiment, the outer side of the stabilizing frame 5 is fixedly connected to the inner wall of the tube body 1. There are two sets of stabilizing frames 5, which are symmetrically distributed front and back. There are four sets of recessed grooves 4, which are distributed in a ring array. One side of the worm gear 13 moves through the limiting seat 3 and is fixedly connected to the handwheel 14. One side of the arc-shaped clamp 15 is in contact with the tube body 1. The setting of the stabilizing frame 5 can enhance the structural strength and rigidity of the tube body 1, making the tube body 1 less prone to deformation and breakage when subjected to large film winding tension, thereby improving the load-bearing capacity and service life of the tube body 1. The uneven surface texture formed between the recessed grooves 4 and the surface of the tube body 1 can significantly increase the friction between the tube body 1 and the plastic film.

[0022] In this embodiment, a limiting rod 11 adapted to the support block 9 is fixedly installed in the inner cavity of the limiting seat 3. The outer side of the limiting rod 11 slides in contact with the inside of the support block 9, the inside of the limiting plate 2 slides in contact with the outer side of the tube body 1, and the outer side of the vertical rod 10 slides in contact with the inside of the limiting seat 3. The limiting rod 11 can limit the support block 9, thereby improving the stability of the support block 9 moving up and down.

[0023] In this embodiment, during use, the tube body 1 is fixed to an external device, and the external device drives the tube body 1 to rotate to wind the film. By turning the handwheel 14 forward, the handwheel 14 drives the worm gear 13 to rotate, the worm gear 13 drives the matching worm wheel 12 to rotate, the worm wheel 12 drives the bidirectional lead screw 6 to rotate, and the bidirectional lead screw 6 drives the screwed moving blocks 7 to move away from each other. The moving blocks 7 drive the support blocks 9 to move away from each other through the connecting rod 8, and the support blocks 9 drive the arc-shaped clamps 15 to move away from each other through the vertical rod 10, so that the arc-shaped clamps 15 are away from the tube body 1. Then the limiting plate 2 is moved, and then the handwheel 14 is reversed to reset the arc-shaped clamps 15 and fix the limiting plate 2, which can limit the film.
