It is an important equipment for post-printing packaging processing.

[0003] At present, die-cutting machines are widely used in packaging printing, label making and other industries. In the die-cutting process, a large amount of dust and debris will be generated due to the cutting of materials.

[0019] The following is combined with Figure 1-3 This application is described in further detail.

[0020] The present application embodiment discloses a die-cutting mechanism of a die-cutting machine. Figure 1-3 A die-cutting mechanism of a die-cutting machine includes a top plate 1, a plurality of connecting columns 2 are fixedly connected to the bottom of the top plate 1, the bottoms of the plurality of connecting columns 2 are fixedly connected to the same bottom plate 3, a guide groove is provided on the inner side of the bottom plate 3, a collecting box 4 is fixedly connected to the bottom of the bottom plate 3, the bottom plate 3 is communicated with the inner side of the collecting box 4 through the guide groove, a first filter screen 5 is fixedly connected to the top of the bottom plate 3, and a limiting mechanism is arranged on the bottom plate 3; the limiting mechanism includes a motor 10, the motor 10 is fixedly connected to the outer side of the bottom plate 3, the output end of the motor 10 is connected to a bidirectional screw rod 11 through a first coupling transmission, and the bidirectional screw rod 11 is away from the motor 10 One end is rotatably connected to the inner side of the base plate 3, and the outer side of the bidirectional screw rod 11 is threadedly connected to two clamping plates 13. The two clamping plates 13 are symmetrically arranged at both ends of the bidirectional screw rod 11. Two grooves 12 are provided on the top of the base plate 3, and the clamping plates 13 are slidably connected to the inner sides of the two grooves 12; when the material is die-cut, the staff starts the motor 10, and the motor 10 drives the bidirectional screw rod 11 at the output end to rotate. When the bidirectional screw rod 11 rotates, the bidirectional screw rod 11 drives the two outer threaded clamping plates 13 to move toward each other along the direction of the groove 12, thereby clamping the object placed inside.

[0021] Reference Figure 1-3 A connecting pipe 14 is provided on the outside of the collecting box 4, and a suction fan 6 is fixedly connected to the outside of the collecting box 4. The collecting box 4 is connected to the suction fan 6 through the connecting pipe 14; during the die-cutting process, a large amount of dust and debris will be generated due to the cutting of the material. The staff can start the suction fan 6. When the suction fan 6 is working, since the bottom plate 3, the collecting box 4 and the interior of the first filter screen 5 are connected, the suction fan 6 works to form a negative pressure on the inside of the collecting box 4. Under the negative pressure, dust and debris enter the inside of the collecting box 4 for collection, which can keep the working environment clean and prevent dust from damaging the equipment.

[0022] Reference Figure 1-3 The inner side of the top plate 1 is fixedly connected with a cylinder 7, and the output end of the cylinder 7 is fixedly connected with a die-cutting component 9.

[0023] Reference Figure 1-3There are two guide rods 8 slidingly connected to the inner side of the top plate 1, and the two guide rods 8 are fixedly connected to the die-cutting assembly 9 at the bottom; start the cylinder 7, and when the output end of the cylinder 7 moves downward, the cylinder 7 drives the die-cutting assembly 9 fixedly connected at the bottom to extend downward. When the die-cutting assembly 9 extends downward, the material set at the bottom can be die-cut; the setting of the guide rods 8 can increase the stability of the device during operation and ensure that the die-cutting assembly 9 extends straight downward.

[0024] Reference Figure 1-3 The die-cutting assembly 9 is composed of a mounting plate, a buffer spring and a die-cutting knife.

[0025] The implementation principle of the die-cutting mechanism of a die-cutting machine in the embodiment of the present application is as follows: when the staff uses this device, the staff can first place the material to be processed on the top of the first filter screen 5, and then the staff starts the cylinder 7. When the output end of the cylinder 7 moves downward, the cylinder 7 drives the die-cutting assembly 9 fixedly connected at the bottom to extend downward. When the die-cutting assembly 9 extends downward, the material set at the bottom can be die-cut; when the material is die-cut, the staff starts the motor 10, and the motor 10 drives the bidirectional screw rod 11 at the output end to rotate. When the bidirectional screw rod 11 rotates, the bidirectional screw rod 11 drives the two outer threaded clamping plates 13 to move toward each other along the direction of the groove 12, so as to clamp the object placed inside, so as to prevent the material from being displaced due to extrusion when the material is die-cast, and no manual limiting is required, thereby ensuring the personal safety of the operator;

[0026] During the die-cutting process, a large amount of dust and debris will be generated due to the cutting of the material. The staff can start the suction fan 6. When the suction fan 6 is working, since the bottom plate 3, the collection box 4 and the interior of the first filter screen 5 are connected, the suction fan 6 works to form a negative pressure on the inner side of the collection box 4. Under the negative pressure, dust and debris enter the inner side of the collection box 4 for collection, which can keep the working environment clean and prevent dust from damaging the equipment. A second filter screen is provided at the connection between the connecting pipe 14 and the suction fan 6 to prevent dust and debris from entering the inner side of the suction fan 6 and damaging the body of the suction fan 6, thereby extending the service life of the suction fan 6.
