Efficient drying device for disposable paper food packaging bags

Abstract

The invention relates to the technical field of paper product manufacturing, and discloses an efficient drying device for disposable paper food packaging bags. The device comprises an inner mounting wheel, an adjusting block is movably connected to the left side of the interior of the inner mounting wheel, and a movable shaft is movably connected to the right side of the adjusting block. Under the cooperative use of an inner drying frame and an outer drying frame, the two faces of the food packaging bags are dried at the same time, the drying efficiency of the packaging bags is better, the situation that the packaging bags are turned over for secondary drying is avoided, the drying efficiency is improved, double cams and T-shaped push rods are used in cooperation to push the drying frames to move outwards, the distance between the two sets of drying frames is increased, and the packaging bags are prevented from buckling deformation; and the distance between conveying wheels is adjusted through the cooperation of the adjusting block, the reset springs and movable shafts, so that the tensioning degree of the paper food packaging bags is adjusted, the food packaging bags can be prevented from deforming and falling off after being dried, the packaging bags can be prevented from being broken in the conveying process, and the drying quality of the paper food packaging bags is improved.

Description

technical field [0001] The invention relates to the technical field of paper product manufacturing, in particular to a high-efficiency drying device for disposable paper food packaging bags. Background technique [0002] The types of existing food packaging bags mainly include plastic bags and paper bags, but plastic bags contain many chemical substances, long-term storage of food is not good for food, and plastic bags are difficult to handle and have a long weathering cycle. The enhancement of paper packaging bags has made more and more applications of paper packaging bags. At the same time, paper packaging also has the advantages of easy processing, low cost, suitable for printing, light weight and foldable, non-toxic, odorless, and pollution-free. [0003] In the production process of paper food packaging bags, the packaging bags need to be dried. At present, most of the drying devices can only dry one side of the packaging bags.

[0002] The types of existing food packaging bags mainly include plastic bags and paper bags, but plastic packaging bags contain many chemical substances, long-term storage of food is not good for food, and plastic bags are difficult to handle and have a long weathering cycle. The enhancement of paper packaging bags is used more and more. At the same time, paper packaging also has the advantages of easy processing, low cost, suitable for printing, light weight and foldable, non-toxic, tasteless, and pollution-free.

[0003] During the production process of paper food packaging bags, the packaging bags need to be dried. At present, most of the drying devices can only dry one side of the packaging bags. When the other side needs to be dried, the packaging bags need to be dried. It is more troublesome to perform secondary drying on the surface of the disk, resulting in poor drying effect, and after drying, the packaging bag may warp due to heat, resulting in uneven surface
