Small package glue supply device of cigarette packing machine

Abstract

The invention discloses a small bag glue supply device for a cigarette packaging machine, which comprises a stud bolt, a valve body and a box piece. A vertical glue inlet hole is opened inside the stud bolt, and a double-layer sealing ring is set on the outside of the upper part. There is an upper glue supply chamber at the bottom, a lower glue supply chamber in the valve body, a valve core is installed in the lower glue supply chamber, the upper wide part of the valve core is a convex head, and a damping cylinder is set on the convex head. , The side of the lower narrow part of the valve core is provided with drainage holes; the damping cylinder is composed of an upper ring piece, a spring and a lower ring seat, the middle part of the lower ring seat is provided with a through hole for installation, and the upper end is provided with an annular groove. The structure design of the invention is reasonable, and the effective stroke of the valve core for glue supply is greatly increased compared with the traditional glue supply device. At the same time, the glue supply position is changed to the glue outlet hole at the center of the lower end, which ensures uniform glue supply and increases the contact area between the glue nozzle and the box. Large, and the indentation at the glue point is not obvious; the traditional V-shaped spring is replaced by a damping cylinder to ensure the normal operation of the spring and prevent clogging when the glue is not supplied for a long time.

Description

technical field [0001] The invention relates to the technical field of packaging equipment, in particular to a small bag glue supply device for a cigarette packaging machine. Background technique [0002] As an important system, the glue supply device of the cigarette packaging machine is mainly used to continuously and evenly supply glue to the small packaging machine as required. At present, in the process of daily equipment troubleshooting and disassembly and inspection of waste glue feeders of YB41 packaging machine, it is found that the glue nozzle is easy to wear, the conical pressure spring is prone to elastic fatigue, and the glue nozzle has a small opening degree or does not work. The specific cause of the failure is: the glue nozzle of the glue supply device is easy to wear, causing the glue to flow out from the gap between the steel ball and the worn glue nozzle, resulting in glue leakage; the excessively worn glue nozzle is easy to produce obvious spot indentatio...

AI Technical Summary

Problems solved by technology

The specific cause of the failure is: the glue nozzle of the glue supply device is easy to wear, causing the glue to flow out from the gap between the steel ball and the worn glue nozzle, resulting in glue leakage; the excessively worn glue nozzle is easy to produce obvious spot indentation or even Puncture the box, in severe cases, the steel ball will fall off from the rubber nozzle; the conical pressure spring is fatigued due to elasticity, the pre-tightening force is too small, and the seal between the steel ball and the valve body is not completely sealed, which may cause glue leakage; the diameter of the steel ball is small, The stroke is extremely short and the opening degree of the glue nozzle is small, which may lead to no glue supply or insufficient glue supply. If the daily cleaning and maintenance are not in place, the glue will stick between the glue nozzle and the steel ball, and the failure will be further aggravated
