Automatic die-cutting machine and die-cutting method for double-sided PE coated paper cup production

Abstract

The invention provides an automatic die-cutting machine and die-cutting method for double-sided PE coated paper cup production. The automatic die-cutting machine comprises a die-cutting mechanism, a conveying mechanism, a guide mechanism, a U-shaped support and a bottom plate, and solves the problems that when double-sided PE coated paper is conveyed and subjected to die-cutting, the movement track cannot be correctly guided, deflection is prone to occurring, and errors of the die-cutting size are caused; in addition, during die cutting, a blade directly falls to cut off, so that the double-sided PE coated paper moves, burrs of a notch are increased, the position of the notch is inclined, and the edge of the fan-shaped paper cup sheet is broken; paper cup pieces are connected with waste materials after die cutting forming, the waste materials need to be manually cleaned, and therefore production efficiency is reduced. The double-sided PE coated paper has buffer time during die cutting, and the double-sided PE coated paper is continuously conveyed, so that more die cutting wastes are generated, the utilization rate of die cutting forming of the double-sided PE coated paper is reduced, raw materials are wasted, the production cost is increased, and the like.

Description

technical field [0001] The invention relates to the technical field of paper cup production, in particular to an automatic die-cutting machine and a die-cutting method for producing double-sided PE coated paper cups. Background technique [0002] A paper cup is a kind of paper container made by mechanically processing and bonding base paper made of chemical wood pulp. The appearance is cup-shaped. Waxed paper cups for frozen food, can hold ice cream, jam and butter, etc. The paper cups used for hot drinks are coated with plastic, and the paper cups are characterized by safety, sanitation, lightness and convenience. It can be used in public places, restaurants, and restaurants, and is a disposable product; paper cups are divided into single-sided PE coated paper cups and double-sided PE coated paper cups. Paper cups produced with double-sided PE-coated paper are called double-sided PE-coated paper cups. The form of expression is: there are PE-coated paper cups on the inside...

AI Technical Summary

Problems solved by technology

[0004] The current die-cutting machine often has the following problems when die-cutting double-sided PE coated paper: the double-sided PE coated paper cannot correctly guide the moving track when it is conveyed for die-cutting, and it is prone to deflection, which will cause die-cutting There is an error in the size; and the blade is directly dropped and cut during die-cutting, which will cause the double-sided PE coated paper to move, resulting in increased incision burrs and tilted incision positions, and fan-shaped paper cups will have broken edges; After die-cutting and forming, it will be connected with waste materials, and waste materials need to be cleaned manually, resulting in a decrease in production efficiency; double-sided PE coated paper has a buffer time during die-cutting, and double-sided PE coated paper is continuously conveyed, which will produce more There will be too much die-cutting waste, thereby reducing the utilization rate of double-sided PE coated paper die-cutting, which will cause waste of raw materials and increase production costs; for this reason, the invention provides a double-sided PE coated paper cup production automation Die-cutting machine and die-cutting method
