Technical Field

The invention relates to the technical field of label processing, in particular to a mould for label paper die cutting.

Background

The label is widely applied in daily life, and finally, a finished label seen in the market is processed by a plurality of working procedures such as printing, die cutting, finished product rolling and the like, wherein the die cutting is an important working procedure in the processing procedures.

Chinese patent with publication number CN205891474U discloses a combined die-cutting machine for label stripping and laminating, which comprises a stripping device for stripping the surface material and the base paper of the label, a bottom cutter cutting device for cutting the stripped label base paper, a first vacuum adsorption conveying device, a second vacuum adsorption conveying device for adsorbing and conveying, a laminating device for laminating the cut label base paper and the surface material, a positioning device for positioning, and a die-cutting device for die-cutting the label after laminating.

However, most of the cutters of the die in the existing die cutting device are fixed, and when the labels with different specifications are required to be die-cut, the die needs to be replaced in a whole set, so that the application range is narrow.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide the die for die cutting of the label paper, which has the effect of increasing the application range of the die.

The above object of the present invention is achieved by the following technical solutions: a die for die cutting of label paper comprises a lower die plate, an upper die plate and a base plate, wherein a plurality of guide grooves are formed in the lower die plate, shaft sleeves which correspond to the guide grooves in a one-to-one mode are connected to the upper die plate, guide pillars are arranged in the shaft sleeves in a penetrating mode, one ends of the guide pillars penetrate through the upper die plate downwards, a guide sleeve is connected to the penetrating ends of the guide pillars, the guide sleeve is matched with the guide grooves in a splicing mode, a plurality of steel balls are embedded in the side wall of the guide sleeve, a compression spring is sleeved outside the guide pillars, and two ends of the compression spring are connected with; a through groove is formed in the upper template, a fixed cutter block is arranged in the through groove, a cutter is arranged on the bottom surface of the fixed cutter block, and the fixed cutter block is fixed with the upper template through a connecting piece; a plurality of fastening screws penetrate through the base plate and are in threaded connection with the upper die plate, and fastening sleeves are sleeved outside the fastening screws.

By adopting the technical scheme, when die cutting is carried out, an operator places a label on the lower template, the base plate is driven to drive the upper template to move downwards, the guide sleeve is abutted against the bottom of the guide groove, the compression spring is compressed along with the continuous descending of the upper template, the label is punched by the cutter, when the labels with different specifications need to be die-cut, the operator twists the fastening screw to detach the base plate, then the fixed cutter block is detached through the connecting piece and replaced by a new fixed cutter block, and then the base plate is fixed with the upper template, so that the application range of the die is increased, the time required by replacing the whole die is saved, and the flexibility is high; when compression spring is compressed, it provides the effect of elastic buffer for the cope match-plate pattern, has reduced the possibility that cutter and lower bolster take place rigid collision, and rolling steel ball then has reduced the frictional resistance that receives when the guide pin bushing removed, does benefit to the smoothness nature that improves the cope match-plate pattern motion.
