According to the polishing machine provided by the embodiment of the disclosure, the dust collection cover 300 is arranged between the polishing wheel 200 and the power part 101, the fan blades 400 rotating synchronously with the polishing wheel 200 are arranged in the dust collection cover 300, the power part 101 is used for synchronously driving the polishing wheel 200 and the fan blades 400 to rotate, when the polishing wheel 200 is used for polishing a workpiece, the fan blades 400 rotating at a high speed and positioned on the upper side of the polishing wheel 200 are used for generating suction air flow, dust and debris generated by polishing are sucked into the dust collection cover 300, the environment in the machining workshop of the polishing machine is cleaned, and the harm of the dust to workers is reduced.

Optionally, both the buffing wheel 200 and the fan 400 are fixedly connected to the rotating shaft of the power part 101. Thus, the buffing wheel 200 and the fan blades 400 synchronously rotate, and when the buffing wheel 200 rotates to buff a workpiece, the fan blades 400 also generate sucked air flow along with the rotation of the buffing wheel 200 to suck dust generated by buffing, so that dust removal is facilitated.

Optionally, the centers of buffing wheel 200 and fan blade 400 are both connected to the spindle, and buffing wheel 200 is located below fan blade 400. Therefore, the polishing wheel 200 and the fan blades 400 are driven synchronously by the power part 101, and dust is removed when the polishing wheel 200 polishes a workpiece.

Optionally, the dust cage 300 is circular and the dust cage 300 has a diameter greater than the diameter of the grinder wheel 200. Thus, the coverage area of the dust collection cover 300 is larger than that of the polishing wheel 200, dust generated during polishing of a workpiece can be better sucked into the dust collection cover 300, and the dust removal rate is improved.

Optionally, the dust collection cover 300 is connected with the housing 100 through a connection seat 301, and a through shaft groove 302 is arranged in the connection seat 301. Thus, the dust collection cover 300 can be fixed on the housing 100, and the rotating shaft 102 on the power part 101 can pass through the connecting seat 301, so that the rotation of the rotating shaft 102 is not influenced while the dust collection cover 300 is fixed.

Optionally, the inner diameter of the shaft groove 302 is larger than the diameter of the rotating shaft 102. Thus, the part of the rotating shaft 102 penetrating through the shaft groove 302 is not contacted with the inner wall of the shaft groove 302, and the rotation of the rotating shaft 102 is not influenced.

Alternatively, the fan blades 400 may have a diameter greater than the diameter of the grinder wheel 200 and less than the diameter of the dust cage 300. Therefore, the area of the suction airflow generated when the fan blade 400 rotates is wider, the fan blade 400 can rotate in the dust collection cover 300 conveniently, the suction amount of dust is increased, and the dust removal rate is increased.

Alternatively, the diameter of fan blade 400 refers to the diameter of the circular area formed by the rotation of fan blade 400. Thus, the circular area formed by the rotation of the fan 400 has a diameter larger than that of the buffing wheel 200, so that the area of the suction airflow generated when the fan 400 rotates is wider.

Optionally, the gap between fan blade 400 and buffing wheel 200 may be adjustable. Thus, the gap between the fan blade 400 and the polishing wheel 200 can be adjusted according to the size of dust particles generated by polishing, so that dust can be smoothly sucked into the dust collection cover 300, and the dust removal rate is improved. For example, the dust particles generated by grinding are large, the mass of the particles is large, the particles are difficult to be sucked into the dust collection cover 300, the position of the fan blade 400 is adjusted to reduce the gap between the fan blade 400 and the grinding wheel 200, the sucked air flow near the grinding wheel 200 is enhanced, and the dust with large particles can be smoothly sucked into the dust collection cover 300.

Optionally, a sleeve 401 is disposed in the center of the fan blade 400, and the fan blade 400 is fixed on the rotating shaft 102 through the sleeve 401. Thus, the gap between the fan blade 400 and the polishing wheel 200 can be adjusted by moving the sleeve 401 on the rotating shaft 102, which is convenient for operation.

Alternatively, the sleeve 401 is fixed to the center of the fan blade 400 by welding. This makes the connection between the fan blade 400 and the sleeve 401 more stable.

Optionally, the sleeve 401 is sleeved on the rotating shaft 102 and can move on the rotating shaft 102. In this way, it is convenient to adjust the gap between fan blade 400 and buffing wheel 200 by moving sleeve 401.

Alternatively, a screw is provided on the sleeve 401, and the sleeve 401 is fixed on the rotating shaft 102 by the screw. Thus, the screw on the sleeve 401 can be rotated to make the end of the screw close to the rotating shaft 102 abut against the rotating shaft 102 to fix the sleeve 401, and further to fix the fan blade 400, which is convenient for operation.

Optionally, the dust cage 300 is provided with an air inlet 303, and the air inlet 303 faces the buffing wheel 200. Therefore, when the fan blade 400 rotates, an air flow is sucked at the air inlet end of the fan blade 400, and the sucked air flow sucks dust generated near the polishing wheel 200 into the dust collection cover 300 from the air inlet 303, so that the dust removal rate is improved.

Optionally, the air inlet 303 is circular, and the diameter of the air inlet 303 is larger than the diameter of the fan 400. Therefore, the dust collection cover 300 is prevented from partially shielding the fan blades 400, dust generated near the polishing wheel 200 can be better sucked into the dust collection cover 300 by suction airflow generated by the air inlet side of the fan blades 400, and the dust removal rate is improved.

Optionally, an air outlet 304 is disposed at a position of the dust collecting cover 300 corresponding to the dust storage groove 306. Thus, the air outlet 304 is arranged to facilitate the guiding out of the air flow sucked into the dust collection cover 300, and the air outlet 304 is arranged at a position corresponding to the dust storage groove 306 to facilitate the collection of dust in the air flow.

Alternatively, the position of the dust cage 300 corresponding to the dust storage groove 306 refers to a circumferential portion of the dust cage 300 above the dust storage groove 306. Therefore, the dust storage groove 306 can better store the dust filtered by the air outlet 304, and the leakage of the dust is reduced.

Optionally, the air outlets 304 are distributed annularly around the circumference of the dust cage 300. Therefore, the air outlet area of the air outlet 304 is increased, and the pressure loss of the sucked air flow in the dust collection cover 300 is reduced.
