When the grinding belt 504 is stretched to a certain extent, the tensioning wheel 505 rises until the grinding belt 504 contacts the limiting member 506, reminding the staff to replace the grinding belt 504.

[0025] The lifting component 4 includes a supporting bracket 401, the bottom of which is connected to the base 1, a connecting plate 402 is connected to the top of the supporting bracket 401, the connecting plate 402 is connected to an electric telescopic rod 403, the bottom output end of the electric telescopic rod 403 passes through the connecting plate 402 and is connected to a lifting member 405, a plurality of sliding rods 404 are connected to the top of the lifting member 405, the connecting plate 402 is provided with a limiting through hole, the limiting through hole corresponds to the sliding rod 404 one by one, the connecting plate 402 is slidably connected to the sliding rod 404, the lifting member 405 is provided with two limiting grooves, the bottom of the sliding handle 501 is provided with two sliding rods, the two sliding rods are slidably connected to the inner wall of the limiting groove, and the bottom of the sliding rod is connected to the sliding plate 502, the electric telescopic rod 403 can effectively improve the lifting height control effect of the device, ensure that the device can accurately control the height of the grinding structure, thereby realizing the compatibility of the device with different plastic parts.

[0029] This device can effectively improve the efficiency of collecting powder generated by grinding plastic parts. Compared with traditional devices, this device can ensure that the powder splashes in one direction compared with the traditional rotational grinding method by adopting a grinding structure of the grinding belt 504, which is convenient for collection.

[0030] When the device is in working state, by placing the plastic material on the top of the support plate 302, rotating the bidirectional screw 304 can make the two clamping parts 303 slide towards each other, thereby achieving the clamping and fixing effect of the plastic part, avoiding the problem of cheapness of the plastic part during the grinding process.

[0031] When the plastic part is fixed, adjusting the electric telescopic rod 403 can make the lifting part 405 be in a suitable position above the plastic part, ensuring that the device can effectively be compatible with plastic parts of different heights.

[0034] When the tensioning wheel 505 rises to a certain extent, the inclination angle of the grinding belt 504 changes due to the rising of the tensioning wheel 505, which causes the grinding belt 504 to contact with the limit piece 506. When the limit piece 506 contacts with the grinding belt 504, it effectively reminds the staff to replace the grinding belt 504 in time. By rotating the inclination angle of the limit piece 506, the detection position can be adjusted according to different types of grinding belts 504.

[0035] When the driving wheel 503 is rotating, the exhaust fan 201 is in an on state, and a negative pressure air environment can be generated on the side of the clamping member 303 through the air inlet nozzle 203, so as to collect and adsorb the powder generated by the grinding belt 504, thereby ensuring the recovery efficiency of the plastic powder of the device and avoiding dust splashing to pollute the environment.

[0036] The device can change the processing mode of all-round dust splashing to directional dust splashing by replacing the grinding head with the grinding belt 504, thereby making the powder easier to collect and recycle.
