[0002] Stone plastic floor, also known as stone plastic floor tile, and its formal name should be "PVC sheet floor", is a new type of floor decoration material developed with high quality and high technology. It adopts natural marble powder to form a solid base layer with a high-density and high-fiber network structure, and the surface is covered with a super wear-resistant polymer PVC wear-resistant layer, which is processed through hundreds of processes. When processing stone plastic floors, it is often necessary to grind the plates.

[0003] Currently, a large amount of dust will be generated during the grinding process of existing plates. The dust will fill the working environment, endangering the physical health of operators and may also cause safety accidents such as dust explosions. Summary of the Invention

The bottom plate is symmetrically connected with two vertical plates at the upper end. A reciprocating lead screw is rotatably connected between the two vertical plates. A rotating assembly for driving the reciprocating lead screw to rotate is installed on the vertical plate. A movable block is threadedly connected to the rod wall of the reciprocating lead screw. The lower end of the movable block is connected with a mounting plate. A cylinder is installed at the lower end of the mounting plate. The piston end of the cylinder is connected with a grinding device. A dust collector is installed at the upper end of the mounting plate. A suction pipe is rotatably connected to the lower end of the dust collector. The lower end of the suction pipe passes through the side wall of the mounting plate and extends downward and is provided with a suction head. A water storage tank is arranged above the bottom plate. The water storage tank is installed at the upper end of the corresponding vertical plate. A water delivery hose is connected to the side wall of one side of the water storage tank. The other end of the water delivery hose is installed with a spray head. The spray head is installed on the mounting plate. A watering assembly for spraying water from the water storage tank is installed on the vertical plate. Two support frames are symmetrically connected to the upper end of the bottom plate. A clamping assembly is installed on the support frame.

[0006] By adopting the above technical solution, during use, place the plate to be polished on the two support frames, start the cylinder, and the cylinder will drive the grinder to move downward. When the grinder contacts the plate, start the grinder, and then rotate the reciprocating screw through the rotating assembly. The rotation of the reciprocating screw will apply a force to the movable block through the thread action. When the movable block receives the force, it will drive the mounting plate to move. The movement of the mounting plate will drive the cylinder and the grinder to move. The movement of the grinder will polish the plate. At the same time, start the vacuum cleaner, and the vacuum cleaner will absorb the dust generated during grinding through the suction pipe and the suction head. At the same time, the water storage tank discharges the cleaning water into the nozzle through the water delivery hose, and the nozzle sprays it onto the surface of the plate to cool the grinder and the plate. At the same time, it can also play the role of dust reduction. Through the above structure, the dust generated during the grinding of the plate can be absorbed, and at the same time, the surface of the plate is sprinkled with water to achieve the effects of dust reduction and cooling, thereby improving the applicability of the device.
