Description

Technical Field

[0001] The utility model relates to the technical field of die-cutting machines, in particular to a cardboard fixing device for a carton raw material die-cutting machine. Background Art

[0002] The die-cutting machine is an important equipment for the post-printing packaging processing and molding of cartons. It is mainly used for die-cutting of some non-metallic materials, self-adhesive stickers, EVA, double-sided tape, electronics, mobile phone pads, etc. Die-cutting means full cutting or half cutting, as well as indentation, hot stamping, lamination, automatic waste discharge and other operations on the corresponding materials. The die-cutting machine uses a template carved from a steel knife, a hardware mold, a steel wire or a steel plate, and applies a certain pressure through the embossing plate to roll and cut the cardboard into a certain shape. After the cardboard is placed on the workbench of the die-cutting machine, the paper pressing roller presses on both sides of the cardboard. The cardboard moves forward under the joint action of the upper and lower sets of conveying rollers and follows the paper feed roller to realize the conveying and die-cutting of the cardboard.

[0003] When the die-cutter is in use, the pressure of the die-cutter can be adjusted to improve the fixing effect of the cardboard by controlling the friction between the paper pressing roller and the cardboard. However, during use, it is found that the effective area between the paper pressing roller and the cardboard is large, which affects the use of the die-cutter and reduces the effective range of the die-cutter. For this reason, we propose a cardboard fixing device for a carton raw material die-cutting machine. Utility Model Content
