Description

Technical Field

[0001] The utility model relates to the technical field of die cutting machines, in particular to an adjustable high-speed die cutting machine. Background Art

[0002] Die-cutting machine is also called die-cutting machine, cutting machine, CNC punching machine, mainly used for die-cutting (full cutting, half cutting), creasing and hot stamping operations, laminating, automatic waste discharge of some corresponding non-metallic materials, self-adhesive, EVA, double-sided tape, electronics, mobile phone rubber pads, etc. The die-cutting machine uses steel knives, hardware molds, steel wires (or templates carved from steel plates), and applies a certain pressure through the embossing plate to roll and cut printed products or cardboard into a certain shape. It is an important equipment for post-printing packaging processing and molding. With the development and progress of society, the demand for a high-speed die-cutting machine is becoming more and more intense.

[0003] Most of the existing die-cutting machines do not have the function of pressing and limiting the material before cutting. Most of them are direct cutting, which is prone to deviation during cutting, affecting the cutting quality and making it particularly inconvenient to use.

[0004] For example, a high-speed die-cutting machine disclosed in Chinese patent CN213890319U has a damping spring, a die-cutting knife, a limit spring and a limit plate. When the die-cutting work is performed, the limit plate will move down while the die-cutting knife moves down, and the limit plate will first fall onto the raw material under the action of the limit spring, and under the elastic action of the spring, the limit plate can press the raw material tightly, which is convenient for the subsequent cutting with the die-cutting knife. This setting realizes limiting before cutting, and prevents material damage during the cutting process. In addition, after the cutting is completed, the vibration motor is used in conjunction with the damping spring to vibrate the discharge plate to prevent the material from adhering to the discharge plate during discharge, so as to avoid affecting the die-cutting work and the material receiving work.

[0005] However, the device cannot limit the conveying of the raw materials during the conveying process, which causes the raw materials to shift during conveying, thereby affecting the film cutting accuracy.

[0006] For this reason, we urgently need to provide a kind of high-speed die-cutting machine that can be adjusted. Utility Model Content
