[0002] Polytetrafluoroethylene (PTFE) pipe is a common high-performance plastic pipe with many excellent physical and chemical properties. During its production and processing, in order to ensure the quality standards of the finished pipe fittings, the pipe diameter is measured to improve quality.

[0003] Traditionally, when using laser diameter gauges to measure pipe diameter, the measurement principle is mainly based on laser scanning or optical shadowing. The outer diameter of the pipe is calculated through the interaction between the laser beam and the pipe being measured. During measurement, the pipe is pushed to the laser diameter gauge position by guide rollers, and then the laser is irradiated for measurement. However, in actual use, it has been found that sometimes, during the processing of PTFE pipes, some dust, impurities, and other foreign objects adhere to the surface, which affects the normal radiation of the laser. This results in the measured pipe data being less accurate and reliable, affecting subsequent normal processing and use. Utility Model Content

[0031] In this embodiment:

[0032] Reference Figure 1-4 The following is a preferred embodiment of the present invention.

[0033] Figure 1 and Figure 2 The device shown is a measuring device for measuring the diameter error of polytetrafluoroethylene (PTFE) pipes, including a laser diameter gauge 1, a control panel 2 mounted on the surface of the laser diameter gauge 1, a laser emission port 3 provided on the inner wall of the laser diameter gauge 1, guide rollers 6 mounted on both sides of the surface of the laser diameter gauge 1, a cleaning device 4 provided on one side of the surface of the laser diameter gauge 1, wherein the cleaning device 4 uses a brush plate 43 to clean foreign objects from the surface of the PTFE pipe, and a connecting component 5 is provided at the bottom of the mounting frame 41.

[0034] Figure 1 , Figure 2 and Figure 3The cleaning device 4 shown includes a mounting frame 41, which is fixedly connected to the surface of the laser diameter gauge 1. Two mounting rods rotatably pass through the surface of the mounting frame 41. A brush plate 43 is fixedly connected to one end of each mounting rod 42, and a stabilizing rod 44 is fixedly connected to the surface of the brush plate 43. The stabilizing rod 44 rotatably passes through the surface of the mounting frame 41. A servo motor 45 is mounted on the surface of the mounting frame 41, and a rotating shaft 46 is mounted on the surface of the mounting frame 41. Meshing gears 47 are fixedly connected to the arc surface of one mounting rod 42, and sprockets 48 are mounted on the arc surface of the other mounting rod 42 and the rotating shaft 46. A chain 49 is mounted on the surface of both sprockets 48. When measuring the diameter error of a polytetrafluoroethylene (PTFE) pipe during processing, the control panel 2 of the laser diameter gauge 1 is first operated to measure the... The standard is set, and then the pipe is inserted into the inner wall of the mounting frame 41 and slides in the inner wall of the guide roller 6. At this time, the servo motor 45 on the mounting frame 41 will start running. Because the mounting rods 42 on the two brush plates 43 are connected by the meshing of the gear 47 and the meshing of the sprocket 48 and chain 49, the two mounting rods 42 on the mounting frame 41 will rotate in opposite directions, so that the bristles of the brush plate 43 slide and rub on the arc surface of the pipe, removing foreign objects and impurities from the surface of the pipe. Then the pipe will be inserted into the interior, and the laser emission port 3 will emit a detection laser to calculate and detect the pipe diameter. At this time, when using the laser diameter measuring instrument 1 to measure the error of the PTFE pipe diameter, it can be ensured that the surface of the pipe is clean and tidy, and it is not easy for foreign objects and dust to adhere, affecting the laser irradiation, thereby ensuring the accuracy and reliability of the measurement results.

[0035] Figure 1 , Figure 2 and Figure 3 The mounting bracket 41 shown has an assembly frame 411 on the side of its surface closest to the laser diameter gauge 1. A reinforcing plate 412 is fixedly connected to the inner wall of the assembly frame 411. The assembly frame 411 and the rubber reinforcing plate 412 allow for the removal of stubborn foreign matter from the arc surface of the pipe fitting through sliding friction. The assembly plate also shields the impurities removed by the brush plate 43, preventing excessive splashing and secondary adhesion. A mounting plate 413 is fixedly connected to the side of the mounting bracket 41 away from the laser diameter gauge 1. The inner wall of the mounting plate 413... A reinforcing ring 414 is fixedly connected. The mounting plate 413 and the sponge material reinforcing ring 414 are set so that when the pipe passes through the mounting plate 413, its arc surface can slide and rub against the reinforcing ring 414, thereby pre-cleaning the impurities on the surface of the pipe. Two stabilizing plates 410 are fixedly connected to the surface of the mounting bracket 41. The stabilizing plates 410 are slidably connected to the chain 49. The setting of the stabilizing plates 410 makes the chain 49 more stably engaged with the sprocket 48 when it is running and rotating, and it is not easy to loosen and disengage.

[0036] Figure 1 , Figure 3 and Figure 4 The connecting assembly 5 shown includes two triangular plates 51, which are respectively connected and fixed to both ends of the mounting bracket 41. Mounting holes 52 are respectively opened around the perimeter of the surface of the triangular plates 51, and bolts 53 are inserted through the inner walls of the mounting holes 52. The bolts 53 are connected and fixed to the surface of the laser diameter gauge 1. When the mounting bracket 41 is installed on the surface of the laser diameter gauge 1, firstly, the triangular plates 51 fixedly connected to both ends of the mounting bracket 41 are brought into contact with one side of the surface of the laser diameter gauge 1. Then, three bolts 53 are respectively inserted into the three mounting holes 52 on the surface of the triangular plates 51. Finally, the bolts 53 are threadedly connected and fixed to the surface of the laser diameter gauge 1.

The positioning plates 54 are connected and fixed to the surface of the laser diameter measuring instrument 1. By setting the positioning plates 54, the triangular plates 51 can be positioned and fixed more quickly and accurately when they are in contact with the surface of the laser diameter measuring instrument 1, which improves the convenience of using the connecting component 5.

[0038] Working principle: When measuring the diameter error of PTFE tubes during processing, firstly, operate the control panel 2 of the laser diameter measuring instrument 1 to set the measurement standard. Then, insert the tube into the inner wall of the mounting frame 41 and slide it in the inner wall of the guide roller 6. At this time, the servo motor 45 (SGM7J type) on the mounting frame 41 will start running. Because the mounting rods 42 on the two brush plates 43 are connected by the meshing of gears 47 and the meshing of sprockets 48 and chains 49, the two mounting rods 42 on the mounting frame 41 will rotate in opposite directions, causing the bristles of the brush plates 43 to slide and rub against the arc surface of the tube, removing foreign matter and impurities from the surface of the tube. Then, the tube will be inserted into the interior, and the laser emission port 3 will emit a detection laser to calculate and detect the tube diameter. When using the laser diameter measuring instrument 1 to measure the diameter error of PTFE tubes, it can ensure that the surface of the tube is clean and tidy, and that foreign matter and dust are not easily attached, which would affect the laser irradiation, thus ensuring the accuracy and reliability of the measurement results.

[0039] When mounting bracket 41 is installed on the surface of laser diameter measuring instrument 1, firstly, the triangular plates 51 fixedly connected at both ends of mounting bracket 41 are respectively brought into contact with one side surface of laser diameter measuring instrument 1. Then, three bolts 53 are respectively inserted into the three mounting holes 52 on the surface of triangular plates 51. Finally, the bolts 53 are threadedly connected and fixed to the surface of laser diameter measuring instrument 1. At this time, the cleaning device 4 can be used more conveniently and quickly, and the components of the cleaning device 4 can be easily inspected and maintained, ensuring the normal use of the cleaning device 4.
