The cleaning device for the capacitive welding interface of the PE pipe includes: a device body 1, a support base 101 is fixedly installed at the bottom of the device body 1, and a positioning mechanism and a cleaning mechanism are arranged on the device body 1;

[0022] The positioning mechanism includes three rotating shafts 2, the rotating shafts 2 are rotatably installed in the device body 1, a first gear 201 is fixedly sleeved on the rotating shafts 2, one end of the rotating shafts 2 extends outside the device body 1 and is fixedly installed with a connecting plate 202, a positioning rod 203 is fixedly installed on the connecting plate 202, a second gear 204 is rotatably installed in the device body 1, the second gear 204 meshes with the first gear 201, and a servo motor 205 is fixedly installed on the device body 1, and the output shaft of the servo motor 205 is fixedly connected with the second gear 204;

[0023] The cleaning mechanism includes a sleeve 3, the sleeve 3 is rotatably sleeved on the device body 1, a fixed plate 301 is fixedly installed on the sleeve 3, two sleeve tubes 302 penetrate through the fixed plate 301, a connecting rod 303 is inserted in the sleeve tubes 302, a spring 304 is fixedly connected to the inner wall of the sleeve tubes 302, one end of the spring 304 is fixedly connected with the connecting rod 303, and an oxide layer scraper 305 is fixedly installed at one end of the two connecting rods 303.

[0024] As Figure 2 shown, two snap rings 306 are fixedly installed on the inner wall of the sleeve 3, two annular grooves are formed on the device body 1, and the snap rings 306 are adapted to the annular grooves;

[0025] By providing a snap ring 306, the sleeve 3 is kept stable when rotating on the outer wall of the device body 1, preventing shaking and falling off.

[0026] As Figure 2 shown, an adjusting screw 4 is threadedly penetrated through the fixing plate 301. One end of the adjusting screw 4 is rotatably connected to a connecting block 401, and both of the sleeves 302 are fixedly connected to the connecting block 401;

[0027] By providing the adjusting screw 4, the adjusting screw 4 can be screwed to rotate, and then the connecting block 401 is pushed to move by the adjusting screw 4, and then the sleeves 302 are controlled to move by the connecting block 401, facilitating the blade edge of the oxide layer scraper 305 to be attached to the outer wall of the pipeline.

[0035] The first step: After sleeving the pipe orifice of the PE pipe outside the three positioning rods 203, the servo motor 205 is then powered on to drive the second gear 204 to rotate. The three first gears 201 meshing with the second gear 204 will be driven to rotate synchronously and in the same direction. Then, the first gear 201 drives the connecting plate 202 to move towards the outer ring of the device body 1 through the rotating shaft 2. At the same time, the positioning rod 203 is driven to support on the inner wall of the pipe to position the inner wall of the pipe.

[0036] The second step: By screwing the adjusting screw rod 4, the edge of the oxide layer scraper 305 can be pushed to abut against the outer wall of the pipe. Then, the stepping motor 5 is powered on to drive the third gear 501 to rotate. Then, the gear ring 502 meshing with the third gear 501 is driven to rotate. Then, after the gear ring 502 drives the sleeve 3 to rotate, the sleeve 3 can drive the oxide layer scraper 305 to scrape the oxide layer along the outer wall of the pipe for cleaning, which is convenient for capacitive welding of the PE pipe.
