Honeycomb paperboard high-precision die-cutting machine and die-cutting method

Abstract

The invention provides a honeycomb paperboard high-precision die-cutting machine and a die-cutting method, and relates to the technical field of paperboard production and processing. The honeycomb paperboard high-precision die-cutting machine comprises a supporting plate vertically fixed to the ground, a top supporting plate horizontally fixed is arranged at the top end of the supporting plate, asecond supporting plate vertically fixed to the top end of the top supporting plate is arranged at the top end of the top supporting plate, three chain wheels are mounted at the front end of the second supporting plate through bearings, and one of the chain wheels is driven by a second servo motor to rotate. According to the honeycomb paperboard high-precision die-cutting machine, bristles are symmetrically arranged on the side walls of a pressing plate at the bottom ends of two adjacent push rods, burrs in chip collecting grooves in the two sides of a punching cutter are brushed out through the bristles, the bottom ends of the push rods are pushed by springs, so that when a movable frame ascends, the punching cutter ascends, and the pressing plate continues to press a honeycomb paperboard; and the bristles on the side walls of the two adjacent pressing plates brush the interiors of the chip collecting grooves in the two sides of the lifted punching cutter, and burrs collected in the chip collecting grooves are swept away.

Description

technical field [0001] The invention relates to the technical field of cardboard production and processing, in particular to a high-precision die-cutting machine and a die-cutting method for honeycomb cardboard. Background technique [0002] Honeycomb cardboard is made according to the principle of honeycomb structure in nature. It connects corrugated base paper into countless hollow three-dimensional regular hexagons by glue bonding method to form a whole force-bearing part-paper core, and glues face paper on both sides of it. A new type of environmentally friendly and energy-saving sandwich structure material, honeycomb paperboard is popular in the market for its light weight, low price, high strength, and recyclability. It has become a new type of green packaging that saves resources and protects the environment. [0003] Existing patent No. CN201822044156.6 discloses a die-cutting machine for honeycomb cardboard, including a waste stripping column, a large-toothed die-cu...

AI Technical Summary

Problems solved by technology

[0004] At present, in the die-cutting process of honeycomb paperboard, the honeycomb paperboard is mainly stacked together neatly. When the cutter is cutting the honeycomb paperboard, because the honeycomb paperboard has a certain degree of bulkiness, the cutter is in the process of cutting the honeycomb paperboard. The cutter presses the surface of the honeycomb paperboard. , it is easy to cause the honeycomb paperboard to slide during the die-cutting process, which affects the die-cutting accuracy of the honeycomb paperboard
