Light environment-friendly paperboard for making packing box and V-groove machine for paperboard processing

Abstract

The invention relates to a light environment-friendly paperboard for making a packing box and a V-groove machine for paperboard processing. The light environment-friendly paperboard comprises an innergummed paper layer, a corrugated paper layer, a grey paperboard layer and an outer gummed paper layer from top to bottom, wherein the inner gummed paper layer is used as an inner packing surface of the packing box, the outer gummed paper layer is used as the outer packing surface of the packing box, and the thickness of the inner gummed paper layer is larger than that of the outer gummed paper layer; 200 g of double gummed paper is selected for the inner gummed paper layer, 95 g of high-strength corrugated paper is selected for the corrugated paper layer, and 600g of double grey paperboard isselected as the grey paper board layer. The V-groove machine is used for cutting the paper board into V-shaped grooves, and the inner gummed paper layer of the paper board is a grooving surface; theV-groove machine comprises a machine frame, a paper board feeding and transferring device, a V-groove cutting device and a paper board discharging device, wherein the paper board feeding and transferring device, the V-groove cutting device and the paper board discharging device are arranged on the machine frame. The paper board is light and environment-friendly and can be used for making the right-angle packing box; and the V-groove machine is capable of realizing automatic feeding and discharging and automatic cutting, complete in functions and high in efficiency.

Description

technical field [0001] The invention relates to the technical field of cardboard manufacturing and processing, in particular to a light-weight and environment-friendly cardboard for making packaging boxes and a V-groove machine for cardboard processing. Background technique [0002] The corners of the packaging box generally have two types of rounded corners and right angles. figure 1 What is shown in is the rounded corners in the packaging box. The rounded corners are usually made by creasing the cardboard with a creasing machine and then folding it. It can be seen from the figure that the packaging box made due to the folding of the cardboard Ruching at inner corners. With the continuous improvement of people's living standards, the requirements for commodity packaging boxes are getting higher and higher. According to market research, right-angle packaging hard boxes are more popular among people, and most of the right-angle packaging hard boxes that exist on the market t...

[0002] The corners of the packaging box generally have two types of rounded corners and right angles. figure 1 What is shown in is the rounded corners in the packaging box. The rounded corners are usually made by creasing the cardboard with a creasing machine and then folding it. It can be seen from the figure that the packaging box made due to the folding of the cardboard Creases at inner corners

With the continuous improvement of people's living standards, the requirements for commodity packaging boxes are getting higher and higher. According to market research, right-angle packaging hard boxes are more popular among people, and most of the right-angle packaging hard boxes that exist on the market today are It is made of gray cardboard, but gray cardboard has the disadvantages of heavy weight, difficult degradation, and inability to handle heavy metal harmful substances, which does not meet the green environmental protection requirements advocated by the state. The existing corrugated cardboard on the market has the advantage of light weight, but due to Due to the limitations of the material of the cardboard itself, the right-angle groove cannot be cut by a V-groove machine, so it can only be used to produce rounded corner packaging boxes, and is usually used to produce some packaging cartons, etc. It is not suitable for the production of high-end gift packaging boxes

[0003] In addition, the V-groove machine in the prior art is usually suitable for cutting V-shaped grooves of some thick gray cardboard, and there is a deviation of the cardboard during the transfer process, which leads to the V-shaped grooves that are cut out. meet the requirements
