Automatic compressing and packaging equipment for waste paper

By feeding hard paper and soft paper onto two separate conveyor belts in the waste paper compression and baling equipment, controlling the mixing ratio, and using a shredder to tear the hard paper, the problems of high porosity and resilience caused by the high proportion of hard paper are solved, resulting in higher density and transportation stability.

AI Technical Summary

Technical Problem

Existing waste paper compression and baling equipment has difficulty effectively controlling the ratio of cardboard to soft paper, resulting in high porosity and strong resilience in the compressed paper bales, making them prone to loosening or breakage during transportation, thus affecting transportation efficiency and safety.

Method used

Two separate weighing conveyor belts are used to feed hard paper and soft paper separately. They are mixed and compressed in a ratio of 3:7 to 4:6. The hard paper is then torn apart by a shredder, and tightened by rigid rollers and restraint belts. A turntable and restraint belts are used to rotate and enhance the compression effect.

Benefits of technology

It improves the density and stability of paper packaging, reduces the damage rate during transportation, and enhances transportation efficiency and safety, with a density increase of approximately 15%-20%.

Abstract

The invention belongs to the technical field of automatic paper packaging, and discloses automatic waste paper compressing and packaging equipment which comprises a compressor packaging machine and weighing conveying belts arranged on the two sides of a feeding port of the compressor packaging machine, and one weighing conveying belt is provided with a pulling machine. A plurality of circumferentially-distributed insertion holes are formed in the rotary disc, hard sticks are inserted into the insertion holes and inserted into the compressed waste paper bag along with the compression process of the extrusion base, one end of each hard stick extends out of the waste paper bag, and the ends of the hard sticks are sleeved with restraint straps for tightening. According to the invention, delivery is carried out by dividing the paper into two lines, and hard paper and soft paper are delivered into a compressor packing machine according to a weight ratio of about 3: 7-4: 6. By controlling the proportion of the soft paper and the hard paper, the packing density of the paper bag is improved, the firmness and the reliability of the paper bag body are enhanced, the packing efficiency is improved, and the damage in the transportation process is reduced.
