Technical Field

[0001] The utility model relates to the technical field of floor grinding equipment, in particular to a wood floor grinding device. Background Technique

[0002] During the production process of wood floors, it is necessary to cut the wood floors into different specifications according to actual situations. There will be burrs on the cut sections, and the sections need to be polished smoothly.

[0003] After retrieval, in the application with the patent application number 202120169262.6, a grinding device for the cutting end face of a wood floor is disclosed, including a grinding platform and a conveying platform. The conveying platform is located at one end of the feeding port of the grinding platform. One side of the middle of the grinding platform is fixedly connected with a grinding motor, and the output end of the grinding motor is fixedly connected with a grinding wheel. Above the grinding platform, a plurality of evenly distributed driving rollers for driving the wood floor to move are arranged. At the bottom of the grinding platform, a driving motor for providing power to the driving rollers is fixedly installed. At both ends of the top of the grinding platform, a first fixing frame and a second fixing frame are respectively fixedly connected. Between the first fixing frame and the second fixing frame, two groups of symmetrically arranged pressing roller groups are arranged. Both ends of the pressing roller group are respectively detachably connected with the first fixing frame and the second fixing frame through connecting pieces. The distance between the bottom of the pressing roller group and the top of the driving roller is the same as the thickness of the wood floor. Above the conveying platform, a plurality of evenly distributed supporting rollers are arranged. The wood floor is located above the supporting rollers. On both sides of the conveying platform, a limiting mechanism for preventing the wood floor from shifting is arranged;

[0004] Although this grinding device for the cutting end face of a wood floor polishes the wood floor by setting a grinding platform and a conveying platform, and first makes the outer wall of the roller fit with the outer wall of the wood floor by adjusting the position of the movable plate to avoid the wood floor from shifting during the movement process, this grinding device for the cutting end face of a wood floor can only polish one side of the wood floor each time, and the grinding efficiency is relatively low.

[0005] Therefore, we propose a wood floor grinding device. Content of the Utility Model
