[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0026] In the embodiment, Figure 1-4 A PE pipe production grinder is given. The utility model includes a workbench 1, a pipe rotating propulsion component 2 is fixedly installed on the top of the workbench 1, a grinding frame 3 is fixedly installed on the top of the workbench 1, the inner side of the grinding frame 3 is fixedly connected to the first support frame 4, the inner side of the grinding frame 3 is slidably connected to the pressing frame 5, the outer side of the pressing frame 5 is fixedly installed with a connecting piece 6, the bottom of the connecting piece 6 is fixedly installed with a spring 11, the bottom of the spring 11 is fixedly connected with a pressing piece 7, the top of the connecting piece 6 is fixedly installed with a limiting sleeve 8, the outer side of the limiting sleeve 8 is provided with a grinding belt 9 extending to the outside of the bottom of the pressing piece 7, and the top of the pressing piece 7 is fixedly installed with a T-shaped pull rod 10 extending to the inside of the limiting sleeve 8.
[0027] Furthermore, the cross section of the T-shaped pull rod 10 is square, and both ends of the transverse ends of the T-shaped pull rod 10 extend to both sides of the limiting sleeve 8 respectively.
[0028] Furthermore, the first support frame 4 is U-shaped, and two symmetrically distributed support balls are rotatably connected to the inner side of the first support frame 4. The pressing frame 5 is in an inverted U-shape and a pressing ball is provided at the inner center.
[0029] Furthermore, the pipeline rotating propulsion component 2 includes a linear motion slide 21 fixed to the top of the workbench 1 , and the movable end of the linear motion slide 21 is connected to the pipeline motion component 22 .
[0030] Furthermore, the pipeline motion component 22 includes an L-shaped connecting base plate 221 connected to the moving end of the linear motion slide 21, and a cylinder 222 with an output end extending above its horizontal end is fixedly installed at the bottom of the L-shaped connecting base plate 221, and a second support frame 223 is fixedly installed at the output end of the cylinder 222. A drive motor 224 is fixedly installed on the outer side of the vertical end of the L-shaped connecting base plate 221, and the output end of the drive motor 224 is fixedly connected to a damping drive roller 225 extending above the second support frame 223.
[0031] Furthermore, the second support frame 223 is U-shaped, and two symmetrically distributed support rollers are rotatably connected to the inner side of the second support frame 223 .
[0032] When the pipeline rotating propulsion component 2 is working, the pipeline can be placed on the top of the support roller so that it is supported by the two support rollers, and the pipeline is moved so that the damping drive roller 225 enters the inside of the pipeline. Then the cylinder 222 pushes the second support frame 223 to move so that the pipeline is supported by the second support frame 223 and the damping drive roller 225, and ensures that the damping drive roller 225 is connected to the pipeline. At this time, the drive motor 224 can directly drive the pipeline to rotate through the damping drive roller 225, and at the same time the linear motion slide 21 is started, which can directly drive the pipeline motion component 22 and the pipeline to move left and right.
[0033] Working principle:
[0034] When in use, first fix one end of the pipe by rotating the pipe propulsion component 2, then pull up the pressing frame 5 so that the gap between it and the first support frame 4 can accommodate the passage of the pipe, start the linear motion slide 21 to move the other end of the pipe between the first support frame 4 and the polishing belt 9, then release the pressing frame 5 to make the polishing belt 9 contact with the pipe. At this time, the overall action of the pipe rotating propulsion component 2 drives the pipe to move while rotating, and polishing can be achieved. When the polishing belt 9 needs to be replaced or maintained, the T-shaped pull rod 10 can be directly pulled to make the spring 11 start to compress. At this time, the gap between the top of the limit sleeve 8 and the bottom of the pressing plate 7 is reduced, so that the polishing belt 9 is loose and can be removed for replacement or adjustment.
