Description

Efficient recovery device for corrugated paper trimming waste

Technical Field

The invention belongs to the technical field of corrugated paper production equipment, and particularly relates to a high-efficiency recovery device for corrugated paper trimming waste.

Background

Corrugated paper is also called kraft paper and leatheroid, the corrugated paper board is formed by bonding surface paper, lining paper, core paper and corrugated paper processed into corrugated flutes, is a common material for paper packing boxes, has lighter weight than wood boxes, hardness and easy cutting in size, and is used for protecting other packaged products from being damaged; in the corrugated paper production industry, in order to ensure the neatness of the rear edge of a rectangular paper board cut from corrugated paper, before the cutting process, the strip-shaped corrugated paper needs to be trimmed, and the trimming can generate waste materials. The traditional trimming waste is directly placed on a production line and is transported to a waste placement place when being gathered to a certain amount. This can cause clutter of the trim station attachment.

Chinese patent with patent number CN211761972U discloses a corrugated paper deburring waste recovery device, including recovery pipeline, ground and wall, the feed inlet has been seted up to recovery pipeline's upper surface, the both sides fixedly connected with slide of feed inlet upper surface, recovery pipeline's inside wall fixedly connected with dust pipe, the dust pipe is apart from the feed inlet to be ten centimeters, the top fixedly connected with unable adjustment base on ground, unable adjustment base's last surface mounting has the suction fan, recovery pipeline and dust pipe all run through the inside in the suction fan. The utility model discloses following beneficial effect has: the waste materials of the trimming are directly put into the recovery pipeline through the trimming parts on the two sides of the corrugated paper, and the waste materials are sucked into a waste material barrel outside a workshop through the high-power suction fan by the recovery pipeline and are packaged and treated, so that the workshop is clean and convenient to manage.

However, in the device of above-mentioned patent, the waste material gets into the recovery pipeline, still has longer distance until the in-process that reaches the waste material bucket, and this process still can produce the dust, and although the inside wall of recovery pipeline is provided with the dust pipe, the opening of dust pipe is little, and it can only adsorb some dust, and most dust still can get into the recovery pipeline along with the waste material, causes a large amount of dust when final discharging tower discharges, and the site environment is still relatively poor.
