Description

Technical Field

[0001] This utility model belongs to the field of PE pipe production technology, and relates to pipes used in PE pipe production, and in particular to a device for removing impurities from the inner wall of pipes used in PE pipe production. Background Technology

[0002] Some PE pipes used for transporting gases have their outer walls coated with polytetrafluoroethylene (PTFE), which greatly enhances the pipe's strength and provides excellent wear resistance. When the PE pipe is pulled out of the injection molding machine, its length often exceeds the standard size. After cooling, it needs to be cut. During this cutting process, some chips inevitably splash into the inside of the PE pipe. Therefore, it is necessary to clean the inner wall of the PE pipe.

[0003] Existing pipe cleaning devices on the market face a series of challenges when cleaning PE pipes of different diameters. Specifically, the adjustment method of the cleaning mechanism is relatively complicated in the process of adapting to different pipe diameters, making it difficult to achieve ideal sealing. This situation undoubtedly brings inconvenience to cleaning the inner walls of PE pipes of various diameters. Therefore, it is urgent to solve this problem. Utility Model Content

A hole communicating with the insertion hole 210 is formed at the bottom of the inner wall of the mounting groove 209. The insertion hole 210 and the corresponding hole are slidably connected to the same sliding rod 211. An arc-shaped mounting base 212 is fixed to the other end of each sliding rod 211. An arc-shaped brush plate 206 is mounted on the side of the arc-shaped mounting base 212 away from the turntable 201. A spring 213 is fixed to the side of each arc-shaped mounting base 212 near the turntable 201, and the other end of the spring 213 is fixedly connected to one end of the inner wall of the mounting groove 209.

[0017] In this utility model, both ends of the multiple fixed shells 205 are provided with communicating slots, and bolts 207 are provided through the inside of the slots. The other end of the multiple bolts 207 is provided with a matching nut 208.

[0018] In this utility model, a mounting plate 2 is fixed to one end of the top of the base 1. A first electric push rod 202 is installed on the end of the mounting plate 2 away from the turntable 201. A protective cylinder 203 is fixed to the output shaft of the first electric push rod 202. A motor 204 is installed on one end of the inner wall of the protective cylinder 203. The output shaft of the motor 204 is fixedly connected to the rotating shaft of the turntable 201.

[0019] In this utility model, the fixing mechanism includes a fixed block 3 with holes fixed at the top center of the base 1. Fixed plates 302 are fixed on both sides of the fixed block 3 with holes. The sides of the multiple fixed plates 302 that are close to each other are provided with interconnected threaded grooves. Threaded rods 303 are adapted to fit inside the threaded grooves. Arc-shaped clamping plates 301 are rotatably connected to the sides of the multiple threaded rods 303 that are close to each other.

[0020] In this utility model, two guide rods 304 are fixed on the side of the multiple arc-shaped clamping plates 301 near the fixing plate 302, and holes for the guide rods 304 to pass through are opened on both sides of the fixing plate 302.

[0021] In this utility model, two sliding grooves 101 are provided at the other end of the top of the base 1, and sliders 401 are slidably provided inside the two sliding grooves 101. The same L-shaped moving plate 4 is fixed on the top of the two sliders 401. A second electric push rod 404 is installed at one end of the top of the base 1, and the output shaft of the second electric push rod 404 is fixedly connected to one end of the L-shaped moving plate 4.

One of the electric telescopic rods 5 is installed at one end of the top of the base 1, and the other electric telescopic rod 5 is installed at the bottom of the inner wall of the L-shaped moving plate 4.

[0023] The working principle of this utility model is as follows: First, the L-shaped moving plate 4 is moved away from the mounting plate 2 via the second electric push rod 404. Then, one end of the pipe passes through the perforated fixing block 3 and abuts against one end of the mounting plate 2. Next, by rotating the threaded rod 303, the arc-shaped clamping plate 301 is squeezed and pushed. Multiple arc-shaped clamping plates 301 clamp and fix the outer wall of the pipe, providing stability during the impurity removal process. Then, the second electric push rod 404 is activated, pushing the L-shaped moving plate 4. The L-shaped moving plate 4 causes the slider 401 to slide inside the groove 101 and approach the other end of the pipe. The other end of the pipe is then pressed against the groove. Finally, the electric telescopic rod 5 is activated, causing the arc-shaped clamping plate 301 to move... The curved support block 501 moves upward, and then the curved support block 501 approaches the bottom of the outer surface of the pipe and supports it. At this time, the characteristics of the spring 213 will squeeze the curved brush plate 206 and drive the curved brush plate 206 to contact the inner wall of the pipe. Then, by running the first electric push rod 202 and the motor 204, the first electric push rod 202 pushes the turntable 201 to move inside the pipe, and the motor 204 drives the turntable 201 to rotate, and drives the curved brush plate 206 to remove impurities from the inner wall of the pipe, thereby achieving the effect of removing impurities from pipes with different inner diameters. The fixing shell 205 can be easily disassembled by the bolts 207 and nuts 208, so that the curved brush plate 206 can be cleaned or replaced.

[0024] In summary, in this utility model, due to the adoption of a cleaning mechanism, when it is necessary to clean the inner wall of the pipe, the pipe is first fixed, and then the motor 204 and the first electric push rod 202 are used. At this time, the spring 213 will squeeze the arc-shaped brush plate 206 and keep the arc-shaped brush plate 206 in contact with the inner wall of the pipe. The motor 204 will drive the turntable 201 to rotate, and then the first electric push rod 202 will push the turntable 201 to move on the inner wall of the pipe, thereby achieving the effect of cleaning the inner wall of pipes with different inner diameters and improving the flexibility of cleaning the pipe.
