The recycled polishing liquid can be filtered by the provided filter bag for easy use. The thickness of the planetary gear plate can be designed according to the actual thickness of the profiling part.

[0020] The beneficial effects of the present invention are:

[0021] In the utility model, the profiling double-sided polishing machine has a conveying and recovery mechanism. A water pump extracts polishing liquid from a polishing liquid tank through a liquid extraction pipe and conveys it to a concave ring through a hose and a second fixed pipe. The polishing liquid in the concave ring is conveyed to a conveying hole through a conveying pipe of an upper polishing plate. The polishing liquid in the conveying hole flows between the upper polishing plate and a lower polishing plate. During the polishing process, the polishing liquid flows back to the polishing liquid tank through a conical bucket and a recovery pipe, thereby realizing the recycling of the polishing liquid. Thus, the polishing liquid can be conveyed and recycled.

[0022] In the utility model, the profiling double-sided polishing machine is configured to sleeve the filter mesh bag on the bottom end of the second fixed tube through a fixing mechanism, and then the two ends of the filter mesh bag are located at the positions of the two clamping blocks. When the knob is turned, the rotation of the knob drives the rotation of the threaded rod, and the rotation of the threaded rod drives the movement of the clamping plate and the clamping block, so that the two clamping blocks abut the two ends of the filter mesh bag, and the two ends of the filter mesh bag abut against one side of the baffle, thereby fixing the filter mesh bag and facilitating disassembly and replacement.

[0023] In the utility model, the polishing liquid can be transported and recycled through the transport and recovery mechanism, and the filter bag can be fixed through the fixing mechanism, and is easy to disassemble and replace. BRIEF DESCRIPTION OF THE DRAWINGS
