A sprocket 12 is provided at the front end of the rotating shaft rod 11, and a chain 13 is sleeved between the sprockets 12. A base 10 is symmetrically fixed at the lower end of the top plate 4 front and back, the shaft rod 11 is restricted in the base 10 and can rotate on the base 10, the sprocket 12 is fixed at the front end of the shaft, and the chain 13 is sleeved on the two sprockets 12. The chain 13 is rotated by rotating the shaft rod 11 and the sprocket 12. The right end of the chain 13 is provided with a lever 14, and the lever 14 extends into the driving block 7. The lever 14 is fixed at the front end of the chain 13 and moves with the chain 13. A groove for accommodating the lever 14 is formed at the left end of the driving block 7, and the lever 14 extends into the driving block 7. The restriction of the driving block 7 by the lever 14 and the cross bar 6 makes the driving block 7 unable to rotate.

[0013] Specifically, a forward and reverse screw rod 16 is rotatably connected between the front and rear side walls of the box body 1, and a smooth rod 17 is provided between the front and rear side walls of the box body 1 and on both sides of the forward and reverse screw rod 16. A clamping block 18 is symmetrically threaded on the outer side of the forward and reverse screw rod 16, and the smooth rod 17 penetrates the clamping block 18. The upper end of the clamping block 18 is symmetrically provided with a supporting rod 19 that penetrates the upper side wall of the box body 1. A roller 20 is sleeved on the outer side of the supporting rod 19. The supporting rod 19 is staggered with the seat roller 2 left and right. This part is used to support and limit the sheet material in the left and right directions to prevent the sheet material from moving left and right during cutting. Both ends of the forward and reverse screw rod 16 extend into the box body 1 and can rotate therein. One end of the forward and reverse screw rod 16 penetrates the box body 1 and is provided with a handle for easy rotation. The outer wall of the screw rod 16 is formed with two sections of external threads with opposite rotation directions, and the two clamping blocks 18 are respectively threadedly connected to the two sections of external threads. The smooth rod 17 passes through the two ends of the clamping block 18 and is fixed to the box body 1. The smooth rod 17 prevents the clamping block 18 from rotating, so that the rotation of the positive and negative screw rods 16 can drive the two clamping blocks 18 to move closer or farther synchronously. The supporting rod 19 symmetrically fixes the upper end of the clamping block 18, and the upper side wall of the box body 1 is formed with strip holes for the supporting rod 19 and the roller 20 to pass through and move. The roller 20 is mounted on the supporting rod 19 and can rotate thereon. The supporting rod 19 and the roller 20 are located on the right side of the circular saw 9, and the plate is pushed and clamped to the middle position by the four rollers 20. At the same time, the rotation of the roller 20 can cooperate with the left and right movement of the plate, and the blocking of the roller 20 can prevent the plate from moving forward and backward.

[0014] Specifically, a first electric cylinder 21 is provided at the right lower end of the top plate 4, a pressure plate 22 is provided at the output end of the first electric cylinder 21, a second electric cylinder 23 is provided at the bottom of the inner cavity of the box body 1, the second electric cylinder 23 is opposite to the first electric cylinder 21 up and down, and a concave block 24 penetrating the upper side wall of the box body 1 is provided at the output end of the second electric cylinder 23, which is used to hold and fix the part of the plate on the right side of the circular saw 9, and if necessary, the same method can be used to hold and limit the left side of the circular saw 9. The first electric cylinder 21 is fixed at the lower end of the top plate 4 with the output end facing downward. The pressing plate 22 is fixed on the output end of the first electric cylinder 21, and the pressing plate 22 corresponds to the seat roller shaft 2 on the right side of the circular saw 9 up and down. The second electric cylinder 23 is fixed in the box body 1 with the output end facing upward. The concave block 24 is fixed on the output end of the second electric cylinder 23, and the concave block 24 corresponds to the pressing plate 22 up and down. A through hole is formed on the upper side wall of the box body 1 for the concave block 24 to pass through. The upper surface of the concave block 24 is consistent with the seat roller shaft 2. The concave block 24 is pushed onto the roller shaft by the second electric cylinder 23 to prevent the roller shaft from rotating. The plate is moved down by the pressing plate 22 to fix the plate for subsequent cutting.

[0015] Working principle: The rolling door panel is mounted on the belt seat roller shaft 2 for transmission. By rotating the forward and reverse screw rods 16, the front and rear opposite clamping blocks 18, support rods 19 and rollers 20 are brought closer to each other. The four rollers 20 push and clamp the panel to the front and rear middle position. At the same time, the panel can still move left and right. The moving conveying panel will make the cutting position correspond to the upper and lower parts of the circular saw 9, and then the output end of the electric cylinder is extended, and the concave block 24 is pushed onto the belt seat roller shaft 2 to organize the rotation of the roller shaft. The lower pressing plate 22 fixes the panel, and then the cutting motor 8 drives the circular saw 9 to rotate, and the driving motor 15 drives the rotating shaft rod 11 and the sprocket 12 to rotate, so that the upper side of the chain 13 faces forward. The lower side rotates backwards and makes the chain 13 between the sprockets 12 rotate one circle. The lever 14 rotates one circle along the trajectory of the chain 13. The lever 14 will drive the driving block 7, the cutting motor 8 and the circular saw 9 to move together. The cross bar 6 and the circular sleeve 5 will cooperate with the movement of the driving block 7. The circular saw 9 is in a lower position when moving from front to back and can cross-cut the plate from front to back. The circular saw 9 is in an upper position when moving from the back to the front and does not contact the plate and resets to cut the plate. Then, the output end of the electric cylinder is retracted to the pressure plate 22 to release the plate and transport the plate again. The next cutting position is matched with the circular saw 9, and the previous operation is repeated to cut the plate one by one.
