Technical Field

[0001] The utility model relates to the technical field of plastic pipe production, in particular to a burr removing device for plastic pipes. Background Art

[0002] During the production of existing plastic pipes, they need to be cut according to a set length. Burrs are likely to appear at the cut pipe ends, and the existence of burrs will affect subsequent processing. Generally, the burrs at the ports need to be removed. In the prior art, for removing the burrs at the ports of plastic pipes, they are all manually polished with sandpaper, which is time-consuming and laborious, with slow working efficiency and poor polishing effect. The existing burr removing devices cannot fix plastic pipes of different specifications, and the fixing effect is poor, which will affect the polishing effect.

The two ends of the lead screw are rotatably connected with the side surfaces of the two left bearing seats, and one end of the lead screw is threadedly connected with the threaded hole on the left end side surface of the moving plate. The slide bar is fixedly connected with the side surfaces of the two right bearing seats, and one end of the slide bar passes through the slide hole on the right end side surface of the moving plate. Although this utility model can effectively remove the burrs outside the plastic pipe, the burrs inside the plastic pipe port cannot be removed, and the annular grinding wheel has a fixed diameter and can only polish plastic pipes of the same specification.

[0032] The operation process of the de-burring device for plastic pipes of the present utility model: Place the plastic pipe on the V-shaped block 305 of the clamping assembly 3. According to the specification of the plastic pipe, adjust the telescopic hydraulic cylinder 306 to make the axial center position of the plastic pipe concentric with the output shaft of the rotating motor 205. Turn on the control button of the cylinder 302, and the cylinder 302 installed on the upper support arm 3011 moves downward to tightly clamp the plastic pipe, and then the cylinder 302 stops working. The feeding motor 401 starts to work, driving the moving frame to slide horizontally on the lead screw 402 to make the plastic pipe move forward. Stop the operation of the feeding motor 401 until the first grinding wheel 203 and the second grinding wheel 204 enter the inner and outer sides of the plastic pipe respectively. Adjust the distance between the de-burring assembly 2 and the plastic pipe. First, move the slider seat 202 on the track to make the outer wall of the first grinding wheel 203 fit the inner wall of the plastic pipe, and lock the slider seat 202 on the guide rail 201 with the adjusting bolt. Then, move the sliding block 206 to slide in the T-shaped groove 2021 in the slider seat 202, and the sliding block 206 drives the second grinding wheel 204 to move to make the outer wall of the second grinding wheel 204 fit the outer wall of the plastic pipe. The fixed ends of the first grinding wheel 203 and the second grinding wheel 204 are respectively installed in the sleeves, so that the first grinding wheel 203 and the second grinding wheel 204 rotate freely in the sleeves.

The first grinding wheel 203 and the second grinding wheel 204 rotate freely in the sleeves, so as to grind and remove the burrs on the plastic pipe. The grinding chips will fall into the collection box 6. After the rotating motor 205 rotates for a specified time, the feeding motor 401 will rotate in the reverse direction, and the lead screw 402 drives the moving block 301 to retreat, so that the plastic pipe is separated from the first grinding wheel 203 and the second grinding wheel 204. Then the cylinder 302 moves in the reverse direction to open the clamping plate 303, and the plastic pipe is taken out. Then continue to install the next plastic pipe on the V-shaped block 305 and repeat the work without adjusting the positions of the clamping assembly and the removing assembly, and continue to work. This device has a simple structure, is applicable to plastic pipes of different specifications, and can remove the internal and external burrs at the ports of the plastic pipes cleanly, with high de-burring efficiency.
