A worker puts a large number of wood strips (8) into the shell (71) through the feeding port (72), and the wood strips (8) roll to the front end on the conveying roller (73) until the wood strips (8) at the front end move to the push plate (78); then the air cylinder 77 drives the push plate 78 and the battens 8 on the push plate 78 to rise through the piston rod, the inverted L-shaped baffle plate (75) rises under the action of the spring 74 to block the battens 8 on the rear side and prevent the battens 8 from rolling down; the push plate 78 and the batten 8 continue to ascend until the upper side wall of the batten 8 is tightly attached to the surface of the abrasive belt, at the moment, the batten 8 is just positioned between the two clamping blocks (54), and then the adjusting head (55) is rotated to enable the clamping block (54) at the right end to move leftwards until the batten (8) is clamped by the two clamping blocks (54); then the air cylinder (77) drives the push plate (78) to move downwards through the piston rod, the push plate (78) pushes the inverted L-shaped baffle plate (75) downwards until the upper surface of the push plate (78) is lower than the position of the front-most batten (8), the spring (74) is compressed, and the front-most batten (8) rolls on the push plate (78) to wait for the next work.

And step two, polishing.

The wood strip grinding machine is characterized in that a motor (2) is started, the motor (2) drives a first chain wheel (21) to rotate, the first chain wheel (21) drives a fourth chain wheel (35) to rotate through a chain, the fourth chain wheel (35) sequentially transmits power to a first rotating shaft (32), a first driving bevel gear (36), a first driven bevel gear (37), a third rotating shaft (34) and a driving belt wheel (38), so that the driving belt wheel (38), the driven belt wheel (39) and an abrasive belt rotate together, and the abrasive belt polishes the upper side wall of a wood strip (8).

And step three, overturning.

The motor (2) drives the second chain wheel (22) and the third chain wheel (23) to rotate, wherein the third chain wheel (23) drives the sixth chain wheel (63) at the left end to rotate through a chain, the sixth chain wheel (63) at the left end sequentially transmits power to the long shaft (62) and the sixth chain wheel (63) at the right end, the sixth chain wheel (63) at the right end drives the fifth chain wheel (43) in the right overturning unit to rotate through the chain, and meanwhile, the second chain wheel (22) drives the fifth chain wheel (43) in the left overturning unit to rotate through the chain;

the fifth chain wheel (43) transmits power to the reduction gearbox (42), the second driving bevel gear (44), the second driven bevel gear (46) and the second rotating shaft (45) in sequence, so that the fluted disc (47) and the cams (48) are driven to rotate, when the roller (52) rolls from the top of the chute (481) to the bottom through the inclined part, the two cams (48) drive the left clamping mechanism and the right clamping mechanism to simultaneously descend so as to drive the batten (8) to descend, so that the batten (8) is separated from the abrasive belt, then the tooth-shaped part of the fluted disc (47) is meshed with the gear (56), the rotation of the fluted disc (47) drives the gear (56) to rotate, the gear (56) drives the ejector rod (51) and the clamping block (54) to rotate so as to drive the batten (8) to rotate, and then when the roller (52) rolls from the bottom of the chute (481) to the inclined part, the tooth-shaped part on the fluted disc (47) is separated from the, because the number of teeth on the fluted disc (47) is 1:4 to the gear (56), the gear (56) rotates 90 degrees at the moment, so that the batten (8) rotates 90 degrees, when the roller (52) rolls to the top of the sliding groove (481), the other side wall of the batten (8) is attached to the surface of the abrasive belt, the other side wall of the batten (8) is ground, and the grinding of the four side walls of the batten (8) is completed in the circulation.

And step four, taking materials.
