Description

Label cutting machine

Technical Field

The invention relates to the technical field of labeling machines, in particular to a label splitting machine.

Background

In the field of label manufacturing, the label paper raw materials are generally wide roll paper of big book, and the mill needs cut label paper according to the order demand, makes it become the label sticker of little book, and at this in-process, needs use the cutting machine. A label slitter is a machine that cuts a wide roll of material longitudinally into rolls of the desired gauge.

Generally, the cutting process of the label paper raw material by the label cutting machine is as follows: at first, the label paper raw materials are segmented, the segmented label paper is installed on a label splitting machine, one end of the label paper is pulled out, conveying rollers on the label splitting machine are sequentially wound around, and finally the label splitting machine is fixed on a label winding core and can cut label stickers in the operation process, and meanwhile, the label winding core rotates to re-wind the cut label paper.

Because the label sticker mainly comprises the base paper and the face paper adhered to the base paper, the face paper is peeled off from the base paper and then adhered to an article needing identification when the label sticker is used, the label sticker has no viscosity under the condition that the base paper is not removed, and the label sticker is easy to unwind after being cut. Therefore, after the label sticker is cut, an adhesive tape needs to be adhered to the surface of the label to fix the end of the label sticker. In a normal state, the ends of the label stickers are fixed in a mode of manually and sequentially pasting one by one, so that the fixing mode has the defect of low efficiency.
