It drives the grinding roller 33 connected to it to rotate through the second driving member 34 (the second driving member 34 is a device that can reciprocate at the driving end, such as: a motor), and the grinding roller 33 drives the grinding belt 32 to rotate, so that the grinding belt 32 can grind the outer wall of the raw material. The clamping unit is a component that can clamp and position the raw material. When the raw material needs to be polished, the staff places the raw material On the clamping unit, the raw material is clamped and positioned by the clamping unit. After the raw material is clamped and positioned, the first driving member 2 (the first driving member 2 is a device whose driving end can perform linear reciprocating motion, such as a cylinder) is started to drive the clamping unit to move toward one end of the grinding belt 32 until the grinding belt 32 and the raw material abut against each other, so that the grinding belt 32 performs a grinding operation on the raw material, and the raw material can be automatically polished, which reduces the labor intensity of the staff and improves the grinding efficiency of the raw material; in the prior art, when the grinding tool is used to grind the raw material, most of the staff need to hold the raw material and then grind the raw material with a grinding wheel, which has a great safety hazard and low grinding efficiency; in this embodiment, when the raw material needs to be polished, the raw material is clamped by the clamping unit, and then the raw material on the clamping unit is pushed by the first driving member 2 to be pressed against the grinder body 3, so that the grinder body 3 performs a grinding operation on the raw material, and the raw material can be automatically polished, which reduces the labor intensity of the staff and improves the grinding efficiency of the raw material.

Since the end of the active round rod 15 close to the clamping tube 10 is a truncated cone The structure 151 makes the truncated cone structure 151 of the active round rod 15 and the inclined surfaces of each clamping rod 12 press against each other, so that each clamping rod 12 slides synchronously toward the outer end of the clamping round tube 10, so that each clamping rod 12 drives the arc panel 13 to slide synchronously toward the outer end of the clamping round tube 10, so that each arc panel 13 presses against the inner wall of the raw material, and at the same time, the arc panel 13 stretches the elastic member 16 (the elastic member 16 is an element capable of telescopic reset, preferably a spring) to a certain extent, so that the elastic member 16 is in a stretched state, so that each arc panel 13 clamps the raw material synchronously, preferably, A rubber pad, a sponge pad or other device with a certain stretching and anti-skid effect can be set on the outer wall of each arc panel 13, so that the contact surface between the arc panel 13 and the raw material has a certain stretching and anti-skid effect, and the first driving member 2 drives the square plate 5 to move toward one end of the grinding belt 32, and the square plate 5 drives the clamping round tube 10, the arc panel 13 and the raw material to move toward one end of the grinding belt 32 through the square plate 5 and the sliding plate 7 until the raw material is pressed against the grinding belt 32, so that the grinding belt 32 performs a comprehensive grinding operation on the raw material; when the grinding of the raw material is completed, the square plate 5 is driven by the first driving member 2 to move toward one end of the grinding belt 32. Move toward one end away from the grinding belt 32, then close the third driving member 8, and drive the sliding plate 7 to slide in the slide groove 6 toward one end away from the flat plate 14 through the fourth driving member 9, so that the active round rod 15 is gradually withdrawn from the clamping round tube 10, so that the active round rod 15 no longer provides extrusion force to each clamping rod 12, so that each clamping rod 12 releases the clamping of the raw material under the rebound action of the elastic member 16, and the staff takes out the polished raw material and then polishes the next raw material. This is repeated, and the raw materials can be automatically polished, which reduces the labor intensity of the staff and improves the polishing efficiency of the raw materials.
