Referring to fig. 6, the auxiliary clamping branch 264 includes a groove 2641, a sliding slot 2642, a sliding block 2643, a mounting spring 2644, a moving rod 2645, a clamping plate 2646 and a clamping spring 2647, the upper and lower sides of the inner wall of the mounting box 25 are symmetrically provided with the groove 2641, the front and rear sides in the groove 2641 are symmetrically provided with the sliding slot 2642, the sliding block 2643 is vertically slidably mounted in the sliding slot 2642, the sliding block 2643 is connected to the sliding slot 2642 through the mounting spring 2644, the moving rod 2645 is mounted between the front and rear sliding blocks 2643 through a hinge, the other end of the moving rod 2645 is rotatably mounted with the clamping plate 2646 through a pin, the clamping plate 2646 is disposed obliquely, one side of the clamping plate 2646 far away from the hole grinding mechanism 24 is connected to the groove 2641 through the clamping spring 2647, during operation, the mounting box 25 is continuously pushed by the electric push rod 27 toward the direction close to the fiber plate, so that the side wall grinding plate 263 and the mounting box body 263 slide relatively to the mounting box 25, the side wall polishing plate 263 slides into the mounting box 25 and pushes the middle portion of the clamping plate 2646 and the end away from the fiber plate to move into the groove 2641, and after the side wall polishing plate 263 moves to a proper position, the clamping plate 2646 performs auxiliary clamping on the upper and lower sides of the stacked fiber plates under the elastic action of the mounting spring 2644 and the clamping spring 2647.

The working steps of the invention are as follows: s1: the round plate type fiberboards are arranged in order and moved to the position above the hole grinding mechanism 24, the round holes in the fiberboards are aligned with the mounting shaft 23, the fiberboards are inserted into the mounting shaft 23, and the fiberboards are stopped to be placed into the round plate type fiberboards after the fiberboards above the round plate 22 are placed to the proper number.

S2: the driving mechanism 43 is pushed by the air cylinder 42 to move downwards and contact with the hole grinding mechanism 24, so that the hole grinding mechanism 24 supports the circular holes of the plurality of fiber boards, and the fiber boards are further arranged in order.

S3: the mounting box body 25 is pushed by the electric push rod 27 to move towards the direction close to the fiberboard, the edge grinding mechanism 26 is synchronously driven to be in elastic contact with the side wall of the fiberboard, then the circular plate 22 is driven to rotate by the rotating motor 28, and then the mounting shaft 23 drives the fiberboard to rotate and carries out edge grinding processing on the side wall of the fiberboard through the edge grinding mechanism 26.

S4: after S2 is completed, the electric push rod 27 continues to push the mounting box 25 to move toward the direction close to the fiberboard and to squeeze the left and right side walls of the fiberboard, and the belt driving mechanism 43 drives the mounting shaft 23 to rotate so that the hole grinding mechanism 24 grinds the inner wall of the circular hole, and then the polished fiberboard is taken down.
