Filter stick center line glue applying device

Abstract

The invention discloses a filter stick center line glue applying device. The filter stick center line glue applying device comprises a communicating tubular structure composed of an L-shaped feeding cylinder, a hydraulic cylinder, a mixing balloon, an inclined pipe and a glue spraying pipe, wherein a piston section of the hydraulic cylinder is sleeved with a piston column, the piston column is connected to a driving wheel through a precession rod, a pressure stabilizing pipe and a pressure stabilizing valve are arranged at the bottom of the piston section, a sealed hopper bin is arranged at the top end of the L-shaped feeding cylinder, an air inlet chamber of the sealed hopper bin communicates with a pressure relief tank and a pressurizing air pump, a liquid inlet chamber communicates witha glue solution tank through a liquid inlet pipe, the inclined pipe is provided with a mixing valve, the glue spraying pipe is provided with a glue spraying valve, the lower portion of the glue spraying pipe is provided with a crane-type nozzle, and an opening of the crane-type nozzle is provided with a rolling motor shaft and a glue applying roller. According to the filter stick center line glueapplying device, the mixing balloon is adopted as a glue spraying pressure stabilizing component, and a non-contact mixing method is achieved through piston reciprocating motion, so that the mixing efficiency is high, cleaning is convenient, operation is easy and convenient, the problems that glue inside an existing glue applying device is difficult to clear, stirring is uneven, the glue supply amount is unstable, and glue liquid is wasted are solved, the glue breaking phenomenon is avoided, applying is uniform, and the filter stick finished product quality is improved.

Description

technical field [0001] The invention relates to the technical field of filter rod production, in particular to a centerline glue sizing device for filter rods. Background technique [0002] The production process of filter rods for cigarette filters mainly includes: multi-stage opening-plasticizer gluing-center line gluing-sealing gluing-drying-slitting-forming and other processes. Among them, the center line glue, commonly known as the center line glue, is generally used to coat the middle of the forming paper to fix the tow and the forming paper to prevent mutual sliding. If the center line glue is not applied during the production process of the filter rod or the amount is not enough, it will make The quality defects of cigarette holder sinking in the finished cigarettes seriously affect the product quality. [0003] The existing centerline glue supply is mainly divided into gear pump conveying, and gear pump conveying is one of the commonly used conveying methods for ce...

AI Technical Summary

Problems solved by technology

[0004] In the actual sizing process, the centerline glue often has problems such as difficult cleaning of the gear pump glue, uneven mixing, unstable glue supply, etc., and even the phenomenon of glue breaking often occurs in the actual production process, and the tow is loose after the glue is broken. , The mouth rod is poorly formed, resulting in a low yield of filter rods and increasing production costs
