Two through holes are provided on the arc plate 502. A hinge seat is fixedly installed on the side of the arc plate 502. The hinge seat shaft is connected to the piston rod of the second electric cylinder 503. The bottom end of the cylinder body of the second electric cylinder 503 is connected to the shaft of the hinge seat installed on the side of the fixed circular plate 110; the pressure roller 504 is rotatably installed in the lower end face bracket at the front end of the arc plate 502; the rack 505 is slidably installed in the through hole on the arc plate 502, the rack 505 and the gear 506 are meshed with each other, and the gear 506 is rotatably installed in the support plate on the arc plate 502.

The upper plate is fixedly connected to the lower end of the rack 505, the upper ends of the spring and the telescopic rod are connected to the upper plate, and the lower ends are connected to the bracket. A movable roller 509 is rotatably installed inside the bracket. The arc plate 502 is pulled down by the second electric cylinder 503 to press the pressure roller 504 to press the steel strip roll. The belt of the steel strip roll is opened manually to prevent the steel strip roll from collapsing outwards at the moment of opening to avoid injury to the operator. The gear 506 is driven to rotate by the second motor 507 to drive the rack 505 to move downward, thereby driving the second telescopic component 508 to move downward to make the movable roller 509 contact the steel strip roll, and the second telescopic component 508 is used for shock absorption, and the movable roller 509 reduces the friction of the steel strip roll.

[0037] Working principle: When the present invention is used, the steel strip roll is first manually put into the roll sleeve shaft 111, and then the locking part 2 is manually pushed to slide along the L-shaped groove 102 so that the inner hole of the rotating ring 202 is sleeved on the roll sleeve shaft 111 and moved to the position of clamping the steel strip roll. The protrusion ring 203 is manually rotated so that the protrusion on it inserts the insertion rod 204 into the hole on the roll sleeve shaft 111 to complete the locking. Since the locking part 2 can be locked at different positions on the roll sleeve shaft 111, it can adapt to steel strip rolls of various sizes; Next, the arc plate 502 is pulled down by the second electric cylinder 503 to make the pressure roller 504 press the steel strip roll tightly, and the strap of the steel strip roll is opened manually to prevent the steel strip roll from collapsing outwards at the moment of opening to avoid injury to the operator. The gear 506 is driven to rotate by the second motor 507 to drive the rack 505 to move downward, and then the second telescopic assembly 508 is driven to move downward to make the movable roller 509 contact the steel strip roll. The second telescopic assembly 508 is used for shock absorption, and the movable roller 509 reduces the friction of the steel strip roll. Then, the first motor 106 drives the first lead screw 107 to rotate, thereby driving the sliding plate 108 to move forward. The two clips on the sliding plate 108 move along the slide slot 104 to the position below the steel belt roll, clamping one end of the steel belt. The first motor 106 drives the first lead screw 107 to reverse, so that the sliding plate 108 pulls the steel belt backward. When the first lead screw 107 reverses, it drives the second bevel gear 114 to rotate, thereby driving the first bevel gear 113 to rotate and then driving the ratchet 112 to rotate. The inner shaft of the ratchet 112 drives the belt roll sleeve shaft 111 to rotate As a result, the steel strip on it is slowly fed. Under the action of the ratchet 112, when the first lead screw 107 rotates forward, the sliding plate 108 moves forward and the outer wheel of the ratchet 112 rotates idly. Only when the sliding plate 108 pulls the steel strip backward, the inner shaft of the ratchet 112 will rotate to cooperate with the feeding. When the sliding plate 108 pulls the steel strip to move to the rear of the lower roller 109, the movable plate 302 is pushed by the telescopic frame 301 to make the upper roller 307 move downward. The upper roller 307 and the lower roller 109 limit the steel strip and reduce the resistance to pulling the steel strip. When the steel strip reaches the specified position, At this time, the steel strip needs to be cut. The telescopic frame 301 continues to press down. At this time, the upper roller 307 rebounds a certain distance and the flattening rod 304 is pressed onto the steel strip for tightening. Then, the first electric cylinder 401 pushes the cutting cover 402 to move down, and the sliding side plate 404 contacts the steel strip for dust prevention. At the same time, the circular saw cutter 406 is started, and the first electric cylinder 401 continues to push the cutting cover 402 to move downward. The circular saw cutter 406 cuts the steel strip, and the motor of the slide rail 405 drives the lead screw to drive the slider to move, thereby driving the circular saw cutter 406 along the cutting groove 103 moves to cut the steel strip, and at the same time, the vacuum cleaner 303 starts to vacuum from the dust suction port 407 to prevent dust from cutting. After cutting, the flattening rod 304 is lifted up by the telescopic frame 301, and the cut steel strip is pulled out by the sliding plate 108 and taken away manually, and then the sliding plate 108 continues to move forward to the position of the cutting groove 103, and the clamp clamps the end of the steel strip and continues to pull it backward to perform the next cutting, completing the automation of the positioning and cutting of the steel strip, making the cutting more accurate, saving labor costs, and saving cutting time.
