Box sealing device of preformed packing box in automatic wrapping packing box unit

Abstract

A box sealing device of a preformed packing box in an automatic wrapping packing box unit achieves sealing of a box body upper cover and seal fins on two sides by being provided with a twice glue spraying mechanism and a matched press box mechanism along a conveying belt. The technical scheme is that the box sealing device comprises a box sealing platform, wherein a top plate located above the box sealing platform and the box sealing platform form a double-layer framework main body, and a conveying mechanism of the preformed packing box is arranged along the longitudinal direction of the box sealing platform. The box sealing deivce is characterized by further comprising a top cover seal folded edge glue spraying mechanism arranged on an upper top plate along the conveying direction of the conveying mechanism, a circulating rolling conveying type top cover press box mechanism, a left tube fin glue spraying mechanism and a right tube fin glue spraying mechanism which are symmetrically located on two sides of the conveying mechanism and a press gathering type press box mechanism of an upper seal fin and a lower seal fin. The preformed packing box is matched with synchronous and homonymous conveying of the conveying mechanism through the circulating rolling conveying type top cover press box mechanism to synchronously achieve station conveying and top cover pressing.

Description

technical field [0001] The invention relates to a sealing device for an automatic packaging box, which belongs to the technical field of packaging machinery, in particular to a sealing device for a preformed packaging box in an automatic box wrapping machine. Background technique [0002] Cartons for secondary packaging of bottled or filled items are usually specially made in the carton factory. In order to facilitate transportation and reduce volume, the cartons that leave the factory are usually stacked into double-layer cardboard, that is, the front, rear, left, and The right sides are interconnected in turn, and the top and bottom surfaces are respectively composed of pairs of upper horizontal folds, upper vertical folds, lower horizontal folds, and lower vertical folds. [0003] When using the above-mentioned cartons for secondary packaging of bottled or filled products, first use the unpacking mechanism to open the double-layer cardboard to form a square tube, then...

AI Technical Summary

Problems solved by technology

This kind of box packing machine needs to be equipped with an unpacking mechanism, and the input cost is relatively high; after the box is formed, a shifting and dropping box packing mechanism is used, that is, the bottle body is pushed sideways and dropped into the formed box, and the distance of the bottle body falling is at least one box. High, the drop distance is long, in order to prevent the bottle from being pushed down, generally there is an anti-fall bottle mechanism, the volume is relatively large, the manufacturing cost is relatively high, and the box forming and bottle falling are carried out step by step, which reduces the packaging efficiency
