The insert piece 7 is conveyed to the shearing groove 26 through the conveying guide rail.

[0034] The working process of the present continuous winding insert slitting and feeding device:

[0035] 1) The driver 2 is pushed out to drive the cutting foot push block 3 and the knife seat assembly to move in the direction of the cutting knife 5. The acting part 14 at the bottom of the movable part 12 moves in the avoidance groove 11.

[0036] 2) When the acting part 14 walks through the avoidance groove 11 and contacts the blocking position 13, at this time, the slot 21 of the upper knife seat 16 is just sleeved on the pin 22 of the insert piece 7, and the knife seat assembly also receives resistance.

[0037] 3) When the resistance received by the knife seat assembly is greater than the elastic force of the elastic part 8, the elastic part 8 starts to compress, and at the same time, the knife seat assembly temporarily stops moving forward.

[0038] 4) The cutting foot push block 3 continues to move and drives the connecting rod assembly to make a closing movement, so that the clamping piece seat 19 drives the clamping piece 4 to rotate counterclockwise until the clamping piece 4 presses the insert piece 7, and the clamping head 24 is clamped in the clamping groove 23, and at the same time, the limiting adjusting part 9 acts on the limiting surface 10.

[0039] 5) At this time, the clamping piece 4 cannot rotate any more, the driving force of the driver 2 is greater than the resistance (the resistance of the blocking position 13) received by the knife seat assembly, the cutting foot push block 3 drives the knife seat assembly to continue to move, and when the knife seat assembly moves, the acting part 14 acts on the blocking surface 15.

[0040] 6) The upper knife seat 16 and the clamping piece 4 clamp the insert piece 7 and drive the insert piece 7 to move. When the insert piece 7 passes through the blade of the cutting knife 5, the waste 31 at the bottom of the pin 22 is subjected to shearing force, so that the pin 22 is separated from the waste 31.

[0041] 7) After the waste 31 is separated, the insert piece 7 will still be subjected to clamping force until it moves to the material taking position. When the insert piece 7 is clamped by the next material taking clamp, the driver 2 can retreat.

[0042] 8) Since the action portion 14 is still acting on the obstruction surface 15, when the cutting foot push block 3 moves backward with the driver 2, the cutting foot push block 3 drives the connecting rod assembly to open, so that the clip seat 19 drives the clip 4 to rotate clockwise, so that the clip groove 23 of the clip 4 is away from the top height of the insert 7;

[0043] 9) When the clip seat 19 drives the clip 4 to rotate clockwise to a certain angle, the limit portion between the clip seat 19 and the upper knife seat 16 prevents it from continuing to rotate. At this time, the cutting foot push block 3 and the knife seat assembly return to the initial position together, completing an action cycle.
