[0007] Specifically, the second adjustment mechanism includes a connecting block, and fixed plates are fixedly installed on the opposite ends of the two connecting blocks. Spring telescopic rods are fixedly installed on the opposite surfaces of the two fixed plates.

When the pipeline is moving, after the first roller or the second roller moves, that is, moves forward or backward, beyond the set range, it indicates that there is an error in the wall thickness of the pipeline and maintenance is required.

[0012] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.
[0013] A wall thickness detection device for plastic pipe production, such as Figure 1-2 As shown, it includes a fixed rod 1 and two fixed blocks 2. Two sets of first adjustment mechanisms are installed at one end of the fixed rod 1. A first roller 3 is installed on one side of the first adjustment mechanism, and the first roller 3 contacts the inner wall of the pipe. Second adjustment mechanisms are installed on the opposite ends of the two fixed blocks 2, and a second roller 4 is installed on one side of the second adjustment mechanism, and the second roller 4 contacts the outer wall of the pipe. The fixed rod 1 is installed at the discharge port, and the plastic pipe passes through the fixed rod 1. The two fixed blocks 2 can be supported by a bracket. After the plastic pipe is produced and processed, the two fixed blocks 2 are respectively located at the front and rear ends of the plastic pipe. After the pipe is produced, the fixed rod 1, the first adjustment mechanism, and the first roller 3 are located in the pipe, and the two first rollers 3 contact the inner wall of the pipe respectively, and the two second rollers 4 contact the outer wall of the pipe. During the movement of the pipe, after the first roller 3 or the second roller 4 moves, that is, moves forward or backward, beyond the set range, it indicates that the wall thickness of the pipe is wrong and maintenance is performed.
[0014] Specifically, the first adjustment mechanism described in this embodiment includes a long strip block 5, one side of the long strip block 5 is fixedly connected to one end of the fixed rod 1, a cavity is provided in the long strip block 5, a moving block 6 is slidably installed in the cavity, the moving block 6 is fixedly connected to the inner wall of one side of the cavity through a spring 7, a through groove is provided on one side of the cavity, an L-shaped rod 8 is fixedly installed on one side of the moving block 6, and the first roller 3 is installed on one end of the longitudinal rod of the L-shaped rod 8. The moving directions of the two moving blocks 6 are opposite, and the front of the moving block 6 located in the front and the back of the moving block 6 located in the rear are fixedly installed with distance sensors. Under the push of the spring 7, the two moving blocks 6 move in opposite directions, driving the two L-shaped rods 8 to move in opposite directions, so that the two first rollers 3 contact the inner wall of the pipeline respectively. After contact, the distance sensor detects the distance between the moving block 6 and the inner wall of the other side of the cavity, which is set as the initial value. During the transmission of the pipeline, the first roller 3 moves on the inner wall of the pipeline. When the first roller 3 changes, the moving block 6 moves in the cavity, and the distance sensor detects the change of distance.
[0015] Further, the second adjustment mechanism described in this embodiment includes a connecting block 9, a fixing plate 10 is fixedly installed on one side of the opposite ends of the two connecting blocks 9, a spring telescopic rod 11 is fixedly installed on the opposite surfaces of the two fixing plates 10, an L-shaped connecting rod 12 is fixedly installed on the movable end of the spring telescopic rod 11, and second rollers are installed on the opposite ends of the two connecting rods 12. A placement cavity is provided in the connecting block 9, and a controller and other components are installed in the placement cavity. A distance sensor is installed on one side of the opposite ends of the two connecting blocks 9, and the distance sensor detects the change in the moving distance of the connecting rod 12. The spring telescopic rod 11 pushes the connecting rod 12 to move toward the pipeline direction, so that the second roller contacts the outer wall of the pipeline. At this time, the distance sensor detects the distance of the connecting rod 12 and sets it as the initial value. During the transportation of the pipeline, the second roller contacts the outer wall of the pipeline. When the wall thickness of the pipeline changes, the second roller changes, and the distance sensor detects that the connecting rod has changed. Through the cooperation of the first roller and the second roller, the wall thickness change can be detected during the transportation of the pipeline.
[0016] Furthermore, a guide groove is provided on one side of the connecting block 9 described in this embodiment, and a guide block 13 is slidably installed in the guide groove, and one side of the guide block is connected to the connecting rod 12. During the movement of the connecting rod 12, the connecting rod 12 can be guided by the cooperation between the guide block and the guide groove to prevent the connecting rod from being offset during the movement.
[0017] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
