Description

Technical Field

[0001] The utility model relates to the technical field of die cutting machines, in particular to a die cutting machine pressure regulating device for a flat-pressing die cutting machine. Background Art

[0002] 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 cut the printed products or cardboard into a certain shape. It is an important equipment for post-printing packaging processing and molding.

[0003] Traditional die-cutting machines generally adjust the die-cutting pressure by adjusting the length of the connecting rod or the actual installation position of the connecting rod. Some also directly adjust the screw length through the lead screw nut. This method is even more undesirable. Due to the thread gap, the pressure change is greater when locking after each adjustment, and there is almost no regularity. The small hole positioning machine uses automatic pressure regulation, but its principle is the same as the second method mentioned above, so it is also inaccurate. The pressure regulating indicator can only actually feedback the value of the pressure change, but there is no way to compensate, because different machines and different working conditions of the same machine will have different pressure changes when locking.

[0004] For this purpose, we propose a die-cutting machine pressure regulating device for a flat-press die-cutting machine. Utility Model Content
