[0002] The die-cutting machine is mainly used for die-cutting (full cutting, half cutting), creasing, hot stamping, laminating and automatic waste discharge of non-metallic materials, cardboard and other materials. It uses steel knives, hardware molds, steel wires (or templates carved from steel plates) to apply a certain pressure through the stamping plate to roll and cut the printed product or cardboard into a certain shape. At this time, the die-cut material on the cardboard is removed to form a leak. With the rapid development of modern manufacturing industry, die-cutting technology, as an important part of the field of material processing, is widely used in the forming, cutting and processing of various materials. The cutting quality and stability directly affect the final quality and production efficiency of the product. In the cutting process of the die-cutting machine, due to the influence of various factors such as material properties, tool wear, mechanical vibration, etc., incomplete cutting sometimes occurs.

[0025] like Figures 1 to 3 As shown, a die-cutting leak detection device includes a workbench 1, a support frame 2 is fixedly connected to the top of the workbench 1, a detection device 3 is arranged inside the support frame 2, and the detection device 3 is used to detect whether the die-cut material after cutting has leaks. The die-cut material is placed on the top of the rotating roller 19, and then the external driving device drives the die-cut material to move on the top of the rotating roller 19. At this time, the die-cutting material is cut by the die-cutting cutting device 20. After the cutting is completed, the die-cutting material will continue to move to one end. When it moves to the bottom of the detection device 3, the detection device 3 is used to detect whether the die-cutting material after cutting has leaks.

[0026] For further information, see Attachment Figures 1 to 3As shown, the detection device 3 includes a support plate 4, which is fixedly connected between the inner walls of the support frame 2, and a fixed plate 5 is fixedly connected to the bottom of the support plate 4. There are two fixed plates 5. The bottom of the support plate 4 is rotatably connected to a rotating rod 6 near the bottom of the side wall of the fixed plate 5, and a telescopic spring 7 is fixedly connected between the top of the rotating rod 6 and the bottom of the fixed plate 5. The bottom of the rotating rod 6 is rotatably connected to an extrusion roller 8, and the outer wall of the extrusion roller 8 is in contact with the die-cutting material. A connecting rod 9 is fixedly connected between the side walls of the rotating rod 6, and a rotating column 10 is slidably connected to the side wall of the connecting rod 9. The top of the support frame 2 is fixedly connected to a detection lamp 21, and the side wall of the support plate 4 is provided with The groove 11, the outer wall of the rotating column 10 is rotatably connected in the groove 11, the top of the support plate 4 is fixedly connected with a fixed column 12 near both sides of the groove 11, the opposite surfaces of the fixed column 12 are fixedly connected with positive and negative electrode blocks 13, the detection lamp 21 and the positive and negative electrode blocks 13 are in electrical connection, the outer wall of the positive and negative electrode blocks 13 is in contact with the outer surface of the detection lamp 21, the top of the support frame 2 is fixedly connected with a power conductor 22, the side wall of the connecting rod 9 is fixedly connected with a slider 14 near one end of the rotating column 10, the outer wall of the rotating column 10 is provided with a slide groove 15, the slider 14 is slidably connected in the slide groove 15, and the inner side wall of the support frame 2 near the detection device 3 is provided with a die cutting device 20;

[0027] After the die-cutting device 20 cuts the die-cutting material, the external driving device will drive the rotating roller 19 to rotate, thereby driving the die-cutting material to continue to move to the bottom of the detection device 3, and one end of the die-cutting material will squeeze one side of the squeezing roller 8, so that the squeezing roller 8 is lifted up and the telescopic spring 7 is contracted, and then the squeezing roller 8 will fit and rotate on the cut die-cutting material, and then the power supply is turned on and the positive and negative electrode blocks 13 are energized. At this time, the power conductor 22 is away from the positive and negative electrode blocks 13, and the detection lamp 21 will not emit a bright light. When the squeezing roller 8 rotates to the die-cutting material that has been die-cut, the power conductor 22 is between the positive and negative electrode blocks 13 and will emit a bright light. The die-cut material is easier to remove, and there is no need for the telescopic spring 7 to squeeze the rotating rod 6 downward with excessive force. The rotating rod 6 only needs to be pressed down and rotated in a direction away from the fixed plate 5 with a small amplitude, and then the rotating rod 6 drives the squeezing roller 8 to apply pressure to the die-cutting material. The cut die-cutting material will fall into the collecting box 16 through the squeezing of the squeezing roller 8. At this time, the rotating Due to the squeezing of the telescopic spring 7 and the lack of support for the die-cutting material, the rotating rod 6 drives the connecting rod 9 to rotate slightly. When the connecting rod 9 moves, it will drive the rotating column 10 to rotate, and then the other end of the rotating column 10 drives the power conductor 22 to leave between the positive and negative electrode blocks 13, and the detection lamp 21 will not emit a bright light, thereby proving that the die-cutting material has passed the inspection. When incomplete cutting occurs due to factors such as tool wear, changes in material properties, and improper operation, the extrusion roller 8 cannot squeeze the die-cutting material into the collection box 16, and then the extrusion roller 8 will stay on the die-cutting material with problems. The telescopic spring 7 and the extrusion roller 8 cannot drive the rotating column 10 to rotate and make the power conductor 22 contact with the positive and negative electrode blocks 13, so that the detection lamp 21 emits a long bright light, and then the incompletely cut leakage part of the die-cutting cutting device 20 can be detected, so as to remind the staff to deal with it in time. At the same time, the die-cutting material can be automatically unloaded without manual unloading, which saves time and effort, has a simple structure, and is easy to use.

[0028] For further information, see Attachment Figure 1 , Figure 4 , Figure 5 As shown, a collection box 16 is fixedly connected to the bottom of the workbench 1, and a plurality of rotating rollers 17 are rotatably connected to the bottom of the inner wall of the collection box 16. The top of the collection box 16 and the bottom of the workbench 1 are interconnected. The qualified die-cutting materials will be squeezed by the extrusion roller 8 and fall to the top of the rotating roller 17. The die-cutting materials will slide on the top of the rotating roller 17 through the slope of the collection box 16 and be transported to the other end of the collection box 16. Then the staff can reach into the collection box 16 through the grab slot 18 to take out the die-cutting materials collected in the collection box 16, thereby realizing automatic unloading.

[0029] For further information, see Attachment Figure 1As shown, the side walls of the material collecting box 16 away from the workbench 1 are provided with convenient grooves 18 , through which the die-cutting materials in the material collecting box 16 can be easily taken out.

[0030] For further information, see Attachment Figure 1 As shown, a plurality of rotating rollers 19 are rotatably connected inside the workbench 1. The length of the rotating rollers 19 arranged on the top of the collecting box 16 is smaller than the length of the rotating rollers 19 on both sides of the workbench 1. The inconsistent lengths of the rotating rollers 19 allow the telescopic spring 7 to drive the rotating rod 6 and the extrusion roller 8 to extrude and discharge the die-cutting material, making it convenient for the die-cutting material to fall into the collecting box 16. At the same time, it can also support the edge of the material that produces waste die-cutting after cutting.
