[0002] Bulletproof plates are industrial products used to protect against munitions, typically made of materials such as silicon carbide ceramics. Primarily used as bulletproof armor, they effectively stop various types of bullets, protecting personnel and critical infrastructure.

[0003] During the production of bulletproof plates, silicon carbide ceramic sheets need to be polished and ground. This is generally done using a surface grinding machine, a precision device used for grinding and polishing workpiece surfaces. Its main function is to grind the workpiece surface using a grinding tool coated with or embedded with abrasive to achieve high-precision machining requirements for flat surfaces, internal and external cylindrical surfaces, conical surfaces, spherical surfaces, threaded surfaces, and other profiles.

[0041] In this embodiment, a cleaning component 6 is designed to achieve the cleaning effect of silicon carbide ceramic sheets. Two vacuum fans 6-1 and two dust collection pipes 6-2 are fixed on the surface of the frame 1. The output end of the vacuum fans 6-1 is connected to the dust collection pipes 6-2, which can continuously generate suction to absorb the dust generated during grinding.

At the same time, start the drive motor 4-10, which drives the transmission rod 4-12 through the drive frame 4-11 to make the moving seat 4-2 move left and right repeatedly. After grinding is completed, continue conveying, replace the next silicon carbide ceramic sheet, and start the dust suction fan 6-1 to make the dust collection pipe 6-2 and the collection cover 6-7 continuously generate suction. At the same time, the sweeping roller 6-6 keeps rotating to suck up and collect the dust generated during grinding and sweeping.
