Reciprocating glue spreading device for paper box forming machine

Abstract

The invention discloses a reciprocating glue spreading device for a paper box forming machine. The reciprocating glue spreading device comprises a base, a glue nozzle and a glue pipe which is communicated with the glue nozzle; a sliding seat is arranged on the top of the base and is connected with the base in a sliding mode; the sliding seat is in hinge connection with one end of a connecting rod; the other end of the connecting rod is in hinge connection on a crank; the crank is in transmission connection with a transmission mechanism; the glue nozzle is fixedly connected to the sliding seat through a vertical rod and a transverse rod; a sliding chute is formed in the crank; a slide block is arranged in the sliding chute; a hinge hole connected with the connecting rod is formed in the slide block; a threaded hole is also formed in the slide block; the threaded hole is internally in threaded connection with an adjusting screw rod. The reciprocating glue spreading device for the paper box forming machine has the characteristics of wide glue spreading range, uniform coating and wide application range.

Description

technical field [0001] The invention relates to a machine for forming cartons and splicing and bonding double sheets of paper, in particular to a device used in the machine for spraying glue on the edge of the butt joint surface of blank box paper. Background technique [0002] In the carton making process, the blank paper of a larger carton is usually made of two pieces of paper bonded by butt joints at the edges. In terms of production, at first this kind of butt bonding of paper was mainly done manually. In actual production, this kind of manual operation has slow operation speed, low production efficiency, high labor intensity of workers, and after butt bonding The size of the base paper is different, the seam is uneven and other defects. In order to overcome the defects of manual butt bonding, after years of continuous exploration and hard work, various carton forming machine manufacturers have developed and produced products that can be produced. Automatic butt-gluin...

Problems solved by technology

In terms of production, at first this kind of butt bonding of paper was mainly done manually. In actual production, this kind of manual operation has slow operation speed, low production efficiency, high labor intensity of workers, and after butt bonding The size of the base paper is different, the seam is uneven and other defects. In order to overcome the defects of manual butt bonding, after years of continuous exploration and hard work, various carton forming machine manufacturers have developed and produced products that can be produced. Equipment for automatic butt bonding of paper on the box production line

In this automatic butt joint bonding equipment, a gluing mechanism is often used to glue the edge of the paper butt joint. The gluing mechanisms used in the current equipment are as follows: one is a butterfly-type gluing mechanism, which is through After sticking liquid glue on the circumference of the butterfly, use the rotation of the butterfly to apply glue to the butt edge of the paper. This gluing method is suitable for cardboard with flat surface, thin thickness and low water absorption. However, when it is applied to corrugated paper with thick and hard paper and uneven surface, due to the uneven surface of corrugated paper, the glue can not be applied evenly and fully, and the glue cannot be applied to the depressions or the amount of glue is insufficient, resulting in the paper being not firmly pasted. The defect of narrow warranty range; the other is the glue spraying mechanism, which has the advantages of good gluing effect and sufficient glue amount after the glue spraying mechanism is used, but due to the position of the glue spraying nozzle of the glue spraying mechanism in actual operation If it is fixed, there is a defect that the spraying area is too concentrated and the width of the spraying glue is narrow, resulting in a small bonding area of ​​the paper, and the defect that the firmness is not high and easy to peel off
