Laminating device for packaging bag production

Abstract

The invention relates to a laminating device for packaging bag production. The laminating device for packaging bag production comprises a bag opening expanding device and a mark pressing device, wherein the bag opening expanding device comprises an upper adsorption plate and a lower adsorption plate; the upper adsorption plate and the lower adsorption plate respectively abut against or are respectively separated from the upper surface and the lower surface of a packaging bag raw material; bag expanding rods are further arranged between the upper adsorption plate and the lower adsorption plate,and the bag expanding rods extend into the packaging bag raw material and are separated towards the two sides so as to expand the packaging bag raw material; the mark pressing device comprises rollers which are rotatably arranged on the bag expanding rods; the multiple groups of rollers are arranged at intervals along the length direction of the bag expanding rods; the outer edge of each roller abuts against the inner wall of the packaging bag raw material; the outer ring of each bag expanding rod is provided with a rotating belt which drives packaging bags to rotate; the rotating direction of each rotating belt is perpendicular to the bag expanding rods; and the outer belt surface of each rotating belt abuts against the outer wall of the packaging bag raw material, and the packaging bagis linked to rotate. With the laminating device, the production efficiency of clothes packaging bags can be effectively improved, and the bottom sealing reliability of packaging bags is ensured.

Description

technical field [0001] The invention relates to the technical field of packaging boxes, in particular to a laminating device for producing packaging bags. Background technique [0002] Apparel packaging bags are different from ordinary packaging bags. Apparel packaging bags are generally large in size, and most of them are made of kraft paper materials. Therefore, it can effectively carry out the packaging of apparel products and make the packaging bags of clothing more expensive. The texture of the packaging bag made of the above-mentioned kraft paper material is different from that of ordinary corrugated paper. It is thinner and softer. Therefore, in the actual packaging bag processing process, the raw material of kraft paper is tubular and has passed through the lamination equipment. Press and fold the raw material of the packaging bag into a cardboard shape. The raw materials of the stacked packaging bags are stacked together and transported to the corresponding use occ...

AI Technical Summary

Problems solved by technology

The raw materials of the stacked packaging bags are stacked together and transported to the corresponding use occasions. The corresponding manufacturers will manually seal the bottom of the raw materials of the packaging bags, and then unfold the sealed packaging bags according to the use requirements. , to carry clothes and other light-weight commodities, the production efficiency of the packaging bags in the prior art is low, and a large amount of labor is required to participate in the production, which is time-consuming and labor-intensive, and there is also the problem of unreliable bottom sealing of the packaging bags.
