[0036] Working principle: Place the purlin cutting device steadily, connect the transmission devices at both ends, start the machine, and the motor 1405 drives the roller 18 to rotate, which drives the grinding belt 13 to rotate. The purlin passes through the roller 15 and enters the transmission mechanism 14 on the right. The motor 1405 drives the lower roller 1402 to rotate, which drives the purlin to continue to move forward. The upper roller 1404 is pushed by the spring column 1403 to fit tightly with the inside of the purlin. As the purlin moves forward, it rotates and positions the purlin at the same time. The purlin enters the limit groove 208 through the transmission. When the set distance is reached, the transmission mechanism 14 stops transmission, and the hydraulic column 209 is started to push the slider 202 along the slide rail 2 06 slides downward, driving the connecting block 203, and then driving the cutting knife 205 downward to cut the purlin. After completion, the hydraulic column 1 209 drives the cutting knife 205 to return upward and stop moving. At this time, the conveying mechanism 14 on the left is started, driving the purlin to continue moving forward. When the cut of the purlin reaches the middle of the limiting groove 11, the conveying mechanism 14 on the left is suspended, and the hydraulic column 12 is started to push the slider 26 to move downward along the slide rail 25. The structure below it drives the grinding belt 13 to move downward. The rotating grinding belt 13 contacts the cut surface of the purlin to grind the burrs on the cut. After completion, it is driven back by the hydraulic column 12, and the hydraulic column 2 12 pauses, at this time, the conveying mechanisms 14 on both sides resume conveying, the front purlin is conveyed into the collecting device, and the rear purlin continues to move forward. When the purlin cut enters the middle of the limiting groove 11, the right conveying mechanism 14 pauses, the hydraulic column 12 starts, drives the rotating grinding belt 13 downward to grind the cut, and returns to its position after completion. The right conveying mechanism 14 resumes conveying, and the purlin enters the left conveying mechanism 14. When it advances to the specified position, the conveying mechanisms 14 on both sides pause, the hydraulic column 1 209 starts, drives the cutting knife 205 to cut the purlin, and returns to its position after completion. Repeat the above cycle, and the entire purlin cutting device automatically runs; if the cutting knife needs to be replaced, When cutting the knife 205, stop the whole device, one person holds the knife to prevent it from falling directly, and one person pulls the handles 305 on both sides, driving the sliding column 301 to slide outward, driving the limit column 303 to slide and squeeze the spring 304, driving the positioning column 302 to slide until it is disengaged from the positioning groove 306, at which time the cutting knife 205 can be taken out, and the handle 305 is released. Under the push of the spring 304, the positioning column 302 returns to its original position. When installing, first pull the handle 305, and then insert the cutting knife 205 from the installation groove 204 to the bottom of the installation groove 204, release the handle 305, the positioning column 302 returns to its original position and engages with the positioning groove 306, and the cutting knife 205 is fixed.
