[0022] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0023] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0024] Example 1

[0025] like Figures 1-5 As shown, a device for detecting the uniformity of the inner wall of a plastic pipe is provided, comprising: a base plate 1, a vertical plate 11 fixedly connected to the top of the base plate 1, a mounting frame 12 fixedly installed on one side of the vertical plate 11, and a display screen 13 fixedly installed on the side of the vertical plate 11 near the mounting frame 12; a clamping assembly disposed in the mounting frame 12 for clamping and fixing the plastic pipe; and a detection assembly disposed on the vertical plate 11 for detecting the uniformity of the plastic pipe.

[0026] Among them, a pneumatic rod 4 is fixedly connected to the top of the base plate 1, and a support block 41 is fixedly installed at the top of the pneumatic rod 4.

[0027] When testing the uniformity of the plastic tube, one end of the plastic tube is clamped and fixed by the clamping assembly. Then, the pneumatic rod 4 is activated to push the support block 41 upward, so that the support block 41 moves to the bottom of the plastic tube to support the plastic tube. Then, the plastic tube is tested by the detection assembly, and the test results are displayed on the display screen 13.

[0028] Example 2

[0029] Based on Embodiment 1, the clamping assembly includes: a movable groove 2, a movable block 21, a bidirectional threaded screw 22, a mounting rod 23, a movable groove 24, and a clamping roller 25. Two movable grooves 2 are provided on one side of the mounting frame 12, and each movable groove 2 is provided with a movable block 21. A bidirectional threaded screw 22 is rotatably connected between the two movable grooves 2. The two movable blocks 21 are threaded to the outside of the bidirectional threaded screw 22. Two mounting rods 23 are rotatably connected to one side of each movable block 21. Two movable grooves 24 are provided on one side of the upright plate 11 to allow the mounting rods 23 to pass through. One end of the mounting rod 23 passes through the movable groove 24 and is fixedly connected to the outside of each of the two movable rods 23. A housing 26 is fixedly installed at the bottom of the mounting frame 12. The bottom end of the bidirectional threaded screw 22 extends to the housing 26 and is fixedly connected to a bevel gear a27. A drive motor 28 is fixedly installed on one side of the housing 26. One end of the drive shaft of the drive motor 28 extends into the housing 26 and is fixedly connected to a bevel gear b29.

[0030] When clamping and fixing one end of the plastic tube, the plastic tube is sleeved onto the electric push rod 3, so that the plastic tube is located between the upper and lower clamping rollers 25. When the drive motor 28 is started, the bevel gear b29 is rotated. The bevel gear b29 meshes with the bevel gear a27, which in turn drives the bidirectional threaded screw 22 to rotate. The bidirectional threaded screw 22 rotates and engages with the two moving blocks 21, which in turn drives the two moving blocks 21 to move relative to each other inside the moving groove 2. The moving blocks 21 drive the upper and lower clamping rollers 25 to move closer together through the mounting rod 23, thereby clamping and fixing one end of the plastic tube.

[0031] Example 3

[0032] Based on Embodiment 1, the detection assembly includes: an electric push rod 3, a detection cylinder 31, an air pipe 32, a pressure sensor 33, an air nozzle 34, a guide frame 35, a piston 36, a support plate 37, and a roller 38. An electric push rod 3 is fixedly installed on the side of the upright plate 11 away from the mounting frame 12. One end of the electric push rod 3 is equipped with a detection cylinder 31. An air pipe 32 is fixedly installed inside the detection cylinder 31. A pressure sensor 33 is fixedly installed at one end of the air pipe 32, and an air nozzle 34 is fixedly installed at the other end. Two guide frames 35 are fixedly connected between the periphery of the air pipe 32 and the inner wall of the detection cylinder 31. Pistons 36 are slidably connected inside the guide frames 35, with the two pistons 36 fixedly mounted on opposite sides. A support plate 37 is fixedly connected, with one side of the support plate 37 extending to the outside of the detection cylinder 31. Rollers 38 are rotatably connected to opposite sides of the support plate 37. One end of the electric push rod 3 is fixedly connected to a connector 39, and a rotating bearing 310 is fixedly installed on the outside of the connector 39. One end of the detection cylinder 31 is fixedly connected to a connecting cylinder 311, which is installed on the outside of the rotating bearing 310. The other end of the detection cylinder 31 is fixedly connected to a rotating rod 312. One end of the air pipe 32 passes through the rotating rod 312 and extends to the outside. Two symmetrically arranged handles 313 are rotatably connected around the rotating rod 312. Two card holders 314 that cooperate with the handles 313 are fixedly connected around the rotating rod 312.

[0033] During testing, the air tube is connected to the air nozzle 34, and air is injected into the air tube 32 through the air nozzle 34. This causes the two pistons 36 to move in opposite directions along the inside of the guide frame 35, pushing the two support plates 37 outward so that the rollers 38 fit against the inner wall of the plastic tube. Then, the air tube is disconnected to stop the inflation. At this time, the air pressure inside the air tube 32 is stable, and the pressure sensor 33 can detect and record the air pressure. Then, the two handles 313 are removed from the two holders 314 and opened. Grasping the two handles 313 and rotating them causes the detection cylinder 31 to rotate through the rotating rod 312. The detection cylinder 31 drives the connecting cylinder 311 to rotate, and the connecting cylinder 311 drives the outer ring of the rotating bearing 310 to rotate. The rotating bearing 310 enables the detection cylinder 31 to rotate smoothly. When the detection cylinder 31 rotates, it drives the two rollers 38 to rotate along the inner wall of the plastic tube through the two support plates 37. When there is an unevenness in the inner wall of the plastic tube... When the roller 38 moves to the protruding position, the inner diameter of the plastic tube narrows, which in turn pushes the support plate 37 back into the guide frame 35 a certain distance. The piston 36 retracts and squeezes the gas inside the air pipe 32, causing the internal gas pressure to rise. When the roller 38 moves to the recessed position, the inner diameter of the plastic tube widens. The pressure sensor 33 detects the change in air pressure and displays the change in air pressure as a curve on the display screen 13. The initial air pressure is 0. The rising air pressure line shows a positive value, and the falling air pressure line shows a negative value. By observing the degree of fluctuation of the curve, it can be determined whether the uniformity of the inner wall of the plastic tube is uniform or within the allowable deviation value. After the test is completed, the air nozzle 34 is pressed to release the gas inside the air pipe 32. The piston 36 loses its restraint and the support plate 37 can retract. Then, the two handles 313 are retracted and inserted into the holder 314. Then, the fixation of the plastic tube is released and it is removed.
