Description

Technical Field

[0001] The utility model relates to the technical field of mechanical devices, in particular to a closed drum type polishing machine. Background Art

[0002] Typically, when grinding metal components, abrasives are applied to the surface of the component using a grinding tool, followed by grinding and polishing to achieve a smooth surface. For irregularly shaped components, the metal component can be fixed to a grinding shaft, which is then rotatably positioned within a material barrel. During rotation, the metal component follows the shaft, rubbing against the abrasive in the barrel to achieve the desired grinding effect. However, this method has some drawbacks: the abrasive tends to accumulate in a single spot within the barrel, remaining stationary. This prevents the metal component from being fully ground, resulting in suboptimal grinding results.

[0003] The purpose of the utility model is to provide a closed drum type smoothing machine which can solve the above problems. Utility Model Content

[0004] The main technical problem solved by the utility model is to provide a closed drum type polishing machine with a streamlined structure and ingenious design. While the rotating shaft drives the parts to rotate, the closed drum drives the abrasive to revolve, ensuring full contact between the parts and the abrasive, avoiding local accumulation of the abrasive, and ensuring the grinding and polishing effect.

[0005] In order to solve the above technical problems, the present invention adopts a technical solution: providing a closed drum type polishing machine, the polishing machine includes a frame, a rotating shaft for mounting parts, a closed drum for placing abrasives, a material receiving box, a first driving mechanism and a second driving mechanism, both ends of the closed drum are rotatably connected to the frame, one end of the first driving mechanism is connected to one end of the closed drum, and the closed drum is driven to rotate by the first driving mechanism;

[0006] The rotating shaft passes through the closed drum and is rotatably connected to the frame, and one end of the second driving mechanism is connected to the rotating shaft, and the rotating shaft is driven to rotate by the second driving mechanism;

[0007] The material receiving box is located directly below the closed drum, and the closed drum is provided with a plurality of material leakage holes for leaking ash.

[0008] Furthermore, the first driving mechanism and the second driving mechanism both include a driving motor, a driving wheel, a driven wheel and a transmission belt. The driving wheel is installed at the power output end of the driving motor, and the driven wheel of the first driving mechanism is installed at the end of the closed drum; the driven wheel of the second driving mechanism is installed at the end of the rotating shaft, and the transmission belt is simultaneously mounted on the driving wheel and the driven wheel. The driving motor drives the driving wheel to rotate, and the transmission of the transmission belt drives the rotating shaft or the closed drum to rotate.

[0009] Furthermore, a drum front door that can be opened or closed is provided in front of the closed drum.

[0010] Furthermore, the material receiving box is a material receiving box with one end high and the other end low, and a discharge port is provided on the lower side of the material receiving box.

[0011] Furthermore, the exterior of the polishing machine is covered with a casing, and the casing is provided with an upper flip cover that can be opened and closed.

[0013] Furthermore, the bottom of the polishing machine is provided with supporting feet.

[0014] The beneficial effects of the utility model are:

[0015] The utility model includes a frame, a rotating shaft for mounting parts, a closed drum for placing abrasives, a material receiving box, a first driving mechanism and a second driving mechanism. The closed drum is driven to rotate by the first driving mechanism; the rotating shaft is driven to rotate the parts together by the second driving mechanism. In this way, the parts can fully contact the abrasives in the closed drum and rub against the abrasives evenly. The abrasives can also rotate evenly during the rotation of the closed drum. The abrasives can be fully utilized and there will be no phenomenon that the abrasives are accumulated at a certain point and remain motionless.

[0016] Furthermore, the closed drum can be turned over with its front door facing downwards, and the abrasive can be directly poured into the receiving box and discharged through the outlet of the receiving box for collection; then new abrasive can be poured into the closed drum without disassembling parts, and the abrasive can be directly replaced until polishing is completed, so the abrasive can be quickly replaced;

[0017] Furthermore, the second driving mechanism can drive the parts to rotate forward and reverse, and the first driving mechanism can drive the roller to rotate forward and reverse. The speed can also be adjusted according to demand, so that the abrasive utilization rate is high.

[0018] Furthermore, during the closed drum process, there are ash leakage holes on the closed drum. During operation, the dust in the abrasive will leak into the receiving box through the leakage holes, which can reduce the dust adhesion to the parts and affect the polishing effect of the parts.
