[0026] See Figures 1-6 , a cutter for a film laminating machine in this embodiment. This cutter can realize the automatic expansion and contraction of the blade during rotation, improving the safety during use. At the same time, it is locked to the tool bar by a pressing piece to prevent lateral movement. It mainly includes a cutter, a paper feeding mechanism, and a laser positioning mechanism 11. The paper feeding mechanism and the laser positioning mechanism 11 are respectively arranged on both sides of the cutter.

[0027] See in detail Figures 1-3 , the cutter includes an inner ring 3, an outer housing 1, and a blade 10. The inner ring 3 is rotatably connected to the center of the upper part of the outer housing 1. A chute communicating with its upper part is opened in the lower part of the outer housing 1. A slide block 6 is arranged in the chute. The blade 10 is fixed to the lower part of the slide block 6 through a cutter head 9, which is convenient for replacing the blade. A reset groove is opened in the middle of the slide block 6. A stop lever 8 fixed to the outer housing 1 is arranged below the reset groove. A first spring 7 is arranged between the stop lever 8 and the top of the reset groove for pushing the slide block to reset. The front part of the outer side of the inner ring 3 is fixedly connected with an ejector rod 5. An arc-shaped limit groove 2 is opened in the inner side of the upper part of the outer housing 1. The ejector rod 5 rotates relative to the outer housing 1 with the center of the inner ring 3 as the axis in the limit groove 2. The right side wall of the ejector rod 5 is inclined to facilitate pushing down the slide block 6. The laser positioning mechanism 11 includes a laser lamp and a gravity induction switch, and the gravity induction switch controls the opening and closing of the laser lamp.

[0028] See in detail Figures 3-4, at least two sets of axially arranged slide rails 4 are fixedly connected to the inner side of the inner ring 3 for mounting the tool on the tool shank and restricting the tool to slide only along the axial direction of the tool shank. An arc-shaped pressing piece 13 with a gradually decreasing width is fixedly connected to the rear part of the inner ring 3. A convex platform 12 corresponding to the pressing piece 13 and a limiting platform 14 corresponding to the slide rail 4 are arranged at the rear side of the upper part of the outer housing 1. The limiting platform 14 is used to limit the rotation angle of the outer ring to 90° when the outer ring 1 rotates.

[0029] See Figures 5-6 , the paper feeding mechanism includes a frame body 19, a slide rod 15 with a paper feeding knife 17, and a reset rod 20. The slide rod 15 is slidably connected to the frame body 19. Convex blocks are fixedly connected to both sides of the middle part of the slide rod 15. Vertical grooves corresponding to the positions of the convex blocks are opened in the upper part of the frame body 19. A second spring 18 is arranged in the vertical grooves. The middle part of the slide rod 15 is of a hollow structure and a clamping groove 16 is opened on one side. A clamping block 22 corresponding to the clamping groove 16 is arranged on the reset rod 20. A third spring 21 is sleeved on the reset rod 20. The reset rod 20 is horizontally arranged in the clamping hole 23 of the frame body 19.

[0030] During use, the tool shank is horizontally arranged on the film laminating machine. When idle, the tool is horizontally arranged. At this time, the tool can move horizontally along the tool shank. When the drawing paper needs to be cut, the tool is rotated to 20 - 60°, the laser lamp is activated, the tool is horizontally moved according to the laser positioning, adjusted to the appropriate position, and then the tool is continuously rotated to 90°. At this time, the pressing piece at the rear side of the tool is pressed tightly against the convex platform, locking the tool and the tool shank, and the tool cannot move horizontally. During the rotation of the tool, the outer housing of the tool drives the slide seat to gradually contact the ejector rod and is ejected from the outer housing by the ejector rod.

[0031] When retracting the tool, the tool is rotated to the horizontal state, the ejector rod gradually disengages from the slide seat, and the slide seat is reset under the action of the first spring to complete the automatic tool retraction.

[0032] When paper feeding is required, press the slide rod to move downward. When the clamping groove and the clamping block are flush, the reset rod retracts under the action of the third spring, making the clamping block snap into the clamping groove to complete the forward movement of the paper feeding knife. When the paper feeding operation is completed, press the reset rod forward to make the clamping block leave the clamping groove and enter the hollow structure of the slide rod. The slide rod is reset under the action of the second spring to complete the recovery of the paper feeding knife.
