One group of feed rollers 32 consists of two feed rollers 32 installed on the same line above and below. The three groups of feed rollers 32 are of the same size and are installed on the same horizontal line. An empty area is arranged between the two feed rollers 32 close to each other above and below for inserting the bamboo slice 100. When the bamboo slice 100 passes between the upper and lower feed rollers 32, it will be squeezed by the upper and lower feed rollers 32. When the feed rollers 32 roll, the squeezed bamboo slice 100 will be translated. A transmission group 33 is arranged at the front of the three feed rollers 32 on the lower side. The transmission group 33 consists of a pulley group and a transmission motor. The three feed rollers 32 on the lower side are driven to rotate in the same direction by the pulley group of the transmission group 33. The motor The direction of rotation of the machine should be clockwise. When the bamboo piece 100 enters between the feeding rollers 32, it will be driven to move to the right. Grinding motors 4 are fixedly installed on the front and rear sides of the upper part of the protective cover 3. The output shaft of the grinding motor 4 is a square shaft.

At this time, the control cylinder 1 41 continues to extend and retract the movable rod, driving the connecting frame 42 to reciprocate up and down. Under the action of the connecting rod 56, the grinding roller 1 52 is pushed to reciprocate back and forth in the guide block 5. Under the action of the support frame 53, the grinding roller 2 54 moves with the grinding roller The brush roller of the grinding wheel 43 moves forward and backward under the drive of the cylinder 1 41, and the two grinding wheels 43 grind the front and rear sides of the bamboo piece 100, and the grinding roller 2 54 and the grinding roller 1 52 grind the upper and lower sides of the bamboo piece 100. The vacuum cleaner 61 collects the grinding debris through the dust suction port 62 and cleans it in time to avoid the dust generated by the bamboo piece 100 during grinding, which affects the processing and production environment and the health of workers. When grinding, the grinding wheel 43 is driven by the cylinder to grind the bamboo piece 100. 43 and the grinding roller 1 52 and the grinding roller 2 54 reciprocate, so that the grinding mechanism and the bamboo piece 100 are in continuous and uniform contact, so that during the grinding process, the surface of the bamboo piece 100 is completely and carefully ground with uniform force. While the grinding is smooth, it avoids grinding omissions or excessive grinding, which leads to poor molding effect of the bamboo piece 100. During the grinding process, the second group of feeding rollers 32 will transfer the bamboo piece 100 to the right to between the third group of feeding rollers 32 on the right to unload the material and complete the processing.
