Packaging paperboard cutting and blanking device

Abstract

The invention relates to a packaging paperboard cutting and blanking device which comprises a workbench. A laser cutting head is arranged on one side of a portal frame of the workbench, a conveying mechanism is arranged on the workbench, and a first driving mechanism used for driving the portal frame to reciprocate on the workbench in the direction parallel to the conveying direction of the conveying mechanism is arranged between the two sides of the portal frame and the workbench. A supporting frame is arranged on one side of the portal frame, and a second driving mechanism used for driving the supporting frame to reciprocate on the portal frame in the direction perpendicular to the conveying direction of the conveying mechanism is arranged between the supporting frame and the portal frame. A vertical first air cylinder and a hinged second air cylinder are arranged on the supporting frame. A connecting rod is hinged to a supporting base. The conveying mechanism conveys packaging paperboards in a reciprocating mode, the first driving mechanism drives the portal frame to move on the workbench in a reciprocating mode, the second driving mechanism drives the supporting frame to move on the portal frame in a reciprocating mode, the first air cylinder and the second air cylinder drive the laser cutting head to ascend or descend or obliquely move in a combined mode, and various kinds of machining requirements are met. And the cutting efficiency and quality of the printed packaging paperboards can be better improved.

Description

technical field [0001] The invention relates to a packaging cardboard cutting and blanking device, which belongs to the technical field of packaging cardboard cutting and processing equipment. Background technique [0002] Packaging and printing cardboard is made of wood, rice straw, etc. as raw materials and then copied on a cardboard machine, or made of corrugated paper on a composite surface paper and bottom paper. Corresponding patterns and characters are printed according to the characteristics of the product. It has high strength and Toughness, pressure resistance, and folding resistance are widely used in packaging applications in electronics, daily chemicals, food, beverages and other industries. Since the packaging cardboard has a certain thickness and surface toughness, it needs to be cut according to specifications or according to a certain shape to cut the cardboard with large horizontal and vertical widths into a size that is convenient for folding and packaging...

AI Technical Summary

Problems solved by technology

[0003] The cardboard cutting device in the prior art uses a focused high-power-density laser beam to irradiate the workpiece, so that the irradiated material is rapidly melted, vaporized, ablated or reached the ignition point, and at the same time, the molten material is blown away by the high-speed airflow coaxial with the beam. In this way, the workpiece can be cut, which has the characteristics of small laser spot, high energy density, and fast cutting speed. However, for the cutting of packaging cardboard with different thickness and slope end edges, the laser cutting head drive in the prior art cannot meet the application requirements. Repetitive operations are required for edge trimming. When the cardboard is conveyed and unloaded, it is difficult to pile up the material directly, which increases the processing process and affects the production efficiency.
