[0002] Die-cutting machines are mainly used for die-cutting and laminating of some non-metallic materials, self-adhesive stickers, EVA, double-sided tape, mobile phone pads, etc. Die-cutting machines use steel knives, hardware molds, and steel wires to apply a certain pressure through the stamping plate to roll and cut printed products or cardboard into a certain shape. They are important equipment for post-printing packaging processing and molding. However, the current die-cutting equipment still has shortcomings. For example, the precise die-cutting positioning device with the authorization announcement number CN218802597U has the following problems when used:

[0003] Before die-cutting the product, manual debugging is required, and it is impossible to cooperate with the main control box to complete automatic positioning. In addition, some existing die-cutting devices will first die-cut and then quickly transfer the die-cut raw materials away during the die-cutting process. During the transmission process, misalignment and deviation are likely to occur, thus affecting the accuracy of the next die-cutting step.

[0004] In view of the above problems, it is urgent to carry out innovative design based on the original die-cutting device. Utility Model Content

[0009] The lower end of the die-cutting plate is movably connected with a plurality of die-cutting heads, and lasers are arranged in the plurality of die-cutting heads.

[0010] Preferably, the central axis of the die-cutting table coincides with the central axis of the top plate, and the central axis of the top plate coincides with the central axis of the pneumatic rod.

[0011] Preferably, auxiliary rails are symmetrically arranged on both sides of the central axis of the die-cutting table, the size of the groove is matched with the thickness of the die-cutting material, and a distance sensor is arranged in the groove.

[0012] Preferably, the pneumatic rod drives the die-cutting plate and the die-cutting head to move up and down for die-cutting.

The two ends of the material are respectively inserted into the inside of the auxiliary track. The two ends of the material are respectively adapted to the position of the groove. After the die-cut material is inserted into the groove, the internal distance sensor monitoring data is zero. Then the material is transferred to the die-cutting table. The laser in the die-cutting head emits light to shine on the raw material. The auxiliary equipment locates the die-cutting position. The position where the laser is aligned is the center point of the die-cutting, thereby improving the accuracy of the die-cutting. During die-cutting, the pneumatic rod pushes the top plate downward under the action of electric control, and the top plate pushes the guide column to move in the guide groove in the guide sleeve. The spring on the guide column plays a role in buffering and protecting the die-cutting head. The die-cutting head and the die-cutting plate are detachable structures.

This device is die-cutting while the raw materials are transmitted in and out. The frequency of die-cutting is adapted to the frequency of rotation of the material reel. When deviation occurs during the transmission process, the value monitored by the distance sensor will change in real time. When the offset value exceeds the set deviation value, it will affect the die-cutting effect. When the staff receives the abnormal signal, they will make timely adjustments to reduce the waste rate of raw materials and save costs. BRIEF DESCRIPTION OF THE DRAWINGS
