Description

Technical Field

[0001] The utility model relates to the field of polishing machines, in particular to a polishing machine with a debris collection function. Background Art

[0002] A polishing machine is an electric tool. It consists of basic components such as a base, a polishing disc, a polishing fabric, a polishing cover and a cap. The motor is fixed on the base, and the tapered sleeve for fixing the polishing disc is connected to the motor shaft by a screw. The polishing fabric is fastened to the polishing disc by a ring. During the use of the polishing machine, due to the rapid friction between the polishing disc and the workpiece, a lot of debris will be generated. If these debris are not handled in time, they will be mixed between the polishing disc and the workpiece surface, causing damage to the workpiece surface.

[0003] According to Chinese patent number CN219819260U, a polishing machine for processing with debris collection is disclosed, including a motor, the output shaft of the motor is fixedly connected to a polishing disc, a connecting frame is installed on the rear side of the motor, and the connecting frame is installed above the polishing table through a moving mechanism, a fixing frame is installed on the outer side of the output shaft of the motor, and a suction cup is fixedly connected to the lower side of the fixing frame, the suction cup is arranged in a ring shape and has a suction groove at the bottom, and a collection groove is arranged inside the connecting frame and a collection box is placed. The above patent scheme and the prior art both provide a mechanism for absorbing debris above the polishing disc, but during the polishing process, due to the rapid rotation of the polishing disc, the debris will be thrown out and the debris is difficult to be absorbed. For this reason, we propose a polishing machine with debris collection function to solve the above problem. Utility Model Content
