Automatic label paper shearing equipment
Technical Field
The invention relates to a shearing device, in particular to an automatic shearing device for label paper.
Background
At present, in order to more conveniently convey label paper and ensure the uniformity of the label paper, label paper which is not cut is generally wound into a cylinder for transportation after production, when a manufacturer needs to use the label paper, the label paper wound into the cylinder needs to be cut into a complete piece of label paper so as to be adhered to a product, but when the label paper is cut into the cylinder, because the radius of each piece of label paper is different, a single piece of label paper at the periphery is not enough to be wound into a circle, and a single piece of label paper inside is not more than wound into a circle, the positions which need to be cut are different when the label paper is cut each time, a worker needs to carefully watch the connection part between the two pieces of label paper when cutting, the cutting efficiency is low, positioning errors are easy to occur when cutting, and because the label paper in the cylinder is directly cut, if the cutting force of the worker is improperly controlled, the label paper drawn to the lower side of the label paper when the label paper on the surface is cut is caused, and the waste of the label paper is caused when the label paper is cut.
In view of the above disadvantages of manual cutting of the label paper, an automatic label paper cutting device is designed, which can replace manual cutting of the label paper, and can also accurately position the cutting position of the label paper and cut the label paper without cutting the label paper below.
