Description

Technical Field

[0001] The invention relates to the technical field of die cutting machines, in particular to a nesting die cutting machine. Background Art

[0002] The die-cutting machine is mainly used for die-cutting, laminating and automatic waste discharge of some corresponding non-metallic materials, self-adhesive, EVA, double-sided tape, electronics, mobile phone rubber pads, etc. It applies a certain pressure to the die cutter to roll and cut the printed product or cardboard into a certain shape. It is an important equipment for post-printing packaging processing and molding. The existing nesting die-cutting machine consists of an upper die and a lower die. The upper die is equipped with a die-cutting knife and a positioning hole, and the lower die is equipped with a positioning pin. The upper die is driven by a driving mechanism to move downward intermittently, driving the die-cutting knife to die-cut the material.

[0003] The driving mechanism of this type of die-cutting machine generally uses an oil cylinder, but the die-cutting is repeated many times and the oil cylinder is prone to oil leakage. In addition, the highest point of the upper die is adjusted by threaded connection. The highest point of the upper die is changed by turning the screw to change the die-cutting depth. However, the precision adjustment of the screw is difficult to process and there is a backlash problem, which affects the processing accuracy. In addition, the upper and lower templates of this die-cutting machine are installed and fixed by screw inlay. When installing the upper and lower templates, the weight can only be supported manually and the screws are screwed in and fixed, which makes assembly difficult. Since this type of die-cutting machine needs to use positioning holes and positioning pins to nest the material, this type of die-cutting machine with fixed upper and lower templates can only be aligned by adjusting the material feed position, and the material alignment is not flexible. Therefore, it is necessary to develop a nesting die-cutting machine to solve the above problems. Summary of the invention
