A slide plate 181 is fixedly connected to the bottom of the slider 184. An electromagnetic plate 185 is fixedly connected to the bottom of the slide plate 181. When the die-cutting machine is working, the processed material will enter the die-cutting component 3 from the feed roller 11 through the guide roller 12. After being processed by the die-cutting component 3, it will be divided into finished products and waste materials, which are respectively sent by the waste roller 13 and the finished product roller 14.

The driven wheel 1 332 drives the driven wheel 2 341 to rotate, providing power for die-cutting. By rotating the threaded rod 315, a vertical downward pressure is applied to the pressure block 314, so as to apply downward pressure to the tool roller 34, so that it can maintain a distance from the supporting roller 33 during operation to complete the die-cutting work.

When the tool 1 343 and the tool 2 344 are installed on the sleeve 347, the pin 1 345 will pass through the through hole 1 349 to enter the limit hole 1 3417, and the limit block 346 will pass through the groove 2 3410 to enter the groove 3 3411.

[0034] Among them, the second rotating shaft 342 is hollow, and an elastic member 3146 is arranged inside the second rotating shaft 342. One end of the elastic member 3146 is fixedly connected to the inner wall of the second rotating shaft 342, and the other end of the elastic member 3146 is fixedly connected to the piston 3413. When the electric telescopic rod 171 is started, it will push the push plate 17 to move, and then the column 173 will horizontally push the piston 3413 to compress the elastic member 3146, and the connecting rod 3414 symmetrically arranged on the piston 3413 will move in the groove three 3411.

[0035] Among them, the piston 3413 is symmetrically fixedly connected with a connecting rod 3414, one end of the connecting rod 3414 is fixedly connected with a second latch 3415, the connecting rod 3414 passes through the third groove 3411 and extends into the second groove 3410, the second latch 3415 is located in the second limiting hole 3418, when the tool 1 343 and the tool 2 344 are installed on the sleeve 347, the second latch 3415 will enter the second limiting hole 3418.

[0036] The rotating shaft 1 331 is fixedly connected with a driven wheel 1 332 , and the driven wheel 1 332 is meshed with the driving wheel 322 . The rotation of the driving wheel 322 drives the driven wheel 1 332 to rotate, thereby driving the rotating shaft 1 331 and the supporting roller 33 to rotate.

[0037] Among them, the second rotating shaft 342 is fixedly connected to the second driven wheel 341, the second driven wheel 341 is meshed with the first driven wheel 332, and a retaining ring 3412 is provided between the sleeve 347 and the second driven wheel 341. The rotation of the first driven wheel 332 drives the second driven wheel 341 to rotate, thereby driving the second rotating shaft 342, the sleeve 347, the first tool 343 and the second tool 344 to rotate.

[0038] Among them, the retaining ring 3412 is fixedly connected to the rotating shaft 342, and a protrusion 34121 is fixedly connected to the retaining ring 3412. When the push plate 17 is pushed, the limit strip 172 will slide out of the slide groove 316 and fit with the protrusion 34121 to limit the angle at which the tool roller 34 stops rotating.

[0039] Embodiment 1:

[0040] like Figure 1-8As shown, in this embodiment, when the rotary die-cutting machine works normally, the control panel on the workbench 2 can control the speed of each component, the disc-shaped material is mounted on the feed roller 11, and the material enters the die-cutting component 3 through the guide roller 12. The output end of the motor 321 drives the driving wheel 322 to rotate, and then drives the driven wheel 1 332 to rotate. The rotation of the driven wheel 1 332 will cause the rotating shaft 1 331 to rotate between a pair of supporting shaft seats 311, and the rotation of the driven wheel 1 332 will drive the driven wheel 2 341 to rotate. The rotation of the driven wheel 2 341 will drive the retaining ring 3412 and the rotating shaft 2 342 to rotate, thereby causing the sleeve 347 mounted on the rotating shaft 2 342 and the tool 1 343 and the tool 2 344 on the sleeve 347 to rotate around the axis of the rotating shaft 2 342 between a pair of tool shaft seats 312, and cooperate with the support roller 33 to die-cut the material passing therebetween, and the finished product and waste material after die-cutting are respectively rolled up by the waste roller 13 and the finished product roller 14.

[0041] When the tool is worn, or the tool needs to be replaced according to production needs, the electric telescopic rod 171 is started, and its output end drives the push plate 17 to move, and pushes the push plate 17 toward the direction of the die-cutting component 3. As the push plate 17 is pushed, the limit strip 172 fixed on one side of the push plate 17 extends out of the slide groove 316, passes through the pressure block 314 to the top of the retaining ring 3412, and the rotation of the second shaft 342 will drive the retaining ring 3412 to rotate. When the protrusion 34121 on the retaining ring 3412 fits with the limit strip 172, the retaining ring 3412 is closed. The motor 321 is turned off to stop the movement of the die-cutting assembly 3. When the push plate 17 is pushed, the cylinder 173 enters the second shaft 342, contacts the piston 3413, and pushes the piston 3413 horizontally. The elastic member 3146 is compressed, and the connecting rod 3414 on the piston 3413 is pushed to move along the groove 3411, so that the second latch 3415 is gradually withdrawn from the second limiting hole 3418 until the fixed connection between the tool 1 343 and the tool 2 344 and the second shaft 342 is released.

[0042] When the push plate 17 is pushed, the push rod 182 will extend from the second through groove 187, thereby driving the connecting rod 183 to rotate. The connecting rod 183 pulls the slider 184 to slide along the support column 16 in the groove 15, driving the slide plate 181 and the electromagnetic plate 185 to move toward each other in the horizontal direction. When the second latch 3415 is disengaged from the second limit hole 3418, the electromagnetic plate 185 will fit with the blade surface of the first tool 343 and the second tool 344 to prevent the tool from falling off the sleeve 347. At this time, the electromagnetic plate 185 is energized, and the electromagnetic plate 1 85 will generate magnetic force to absorb tool 1 343 and tool 2 344, start the electric telescopic rod 171 to shrink it, drive the push plate 17 away from the die-cutting component 3, and then make the push rod 182 pass through the through slot 2 187 and retract into the carrying unit 1. At this time, the slider 184 will drive the slide plate 181 and the electromagnetic plate 185 to move relative to each other, and at the same time separate tool 1 343 and tool 2 344, and the pin 1 345 will be disengaged from the limit hole 1 3417, the tool will be removed from the sleeve 347, and the electromagnetic plate 185 will be powered off, so that the tool can be removed from the die-cutting machine.

[0043] To install the tools, tool one 343 and tool two 344 need to be placed on the electromagnetic plate 185, the electromagnetic plate 185 needs to be energized, and the electric telescopic rod 171 needs to be started. The above steps need to be repeated until the pin one 345 enters the limiting hole one 3417. At this time, the electromagnetic plate 185 needs to be powered off. Tool one 343 and tool two 344 will be left on the sleeve 347, the limiting block 346 will pass through the groove two 3410 and enter the groove three 3411, the connecting rod 3414 will pass through the groove three 3411 and enter the groove two 3410, and then the electric telescopic rod 171 will be retracted, and the elastic member 3146 will push the piston 3413 to reset, thereby causing the pin two 3415 on the connecting rod 3414 to enter the limiting hole two 3418, thereby fixing tool one 343 and tool two 344 on the sleeve 347.

[0044] It should be noted that the tool 1 343 and the tool 2 344 are combined into a cylindrical shape, and the opposite sides of the pair of electromagnetic plates 185 are arc-shaped, and their diameters are the same as the outer diameter of the cylinder formed by the tool 1 343 and the tool 2 344 .
