Bi-component adhesive preparation device with magnetic stirring and overturning adhesive discharging functions

Abstract

The invention discloses a bi-component adhesive preparation device with magnetic stirring and overturning adhesive discharging functions, which is used for uniformly stirring and mixing as well as filling and dispensing a quick-drying adhesive according to a certain proportion with good fluidity. The bi-component adhesive preparation device with magnetic stirring and overturning adhesive discharging functions comprises material storage barrels for respectively holding components A and B, pipelines for enabling single-component adhesives to flow into a mixer, and the mixer, and is characterizedin that a double-control valve is arranged between the pipelines for two single-component adhesives to flow into the mixer; a wide-mouth adhesive nozzle serving as the mixer and a stirrer are arranged below the double-control valve; a mechanism for positioning and overturning the wide-mouth adhesive nozzle to pour out the adhesive at a determined position and can restore to the original positionis arranged; the stirrer consists of a stirring bar arranged in the wide-mouth adhesive nozzle and a controllable magnetic rotator arranged in a rotating body close to the bottom of the wide-mouth adhesive nozzle; and a mechanism for coordinated action is arranged between / among a valve body, a wide-mouth adhesive nozzle combination and / or the stirrer. Because an adhesive path in the mixer is wide,the inner wall is smooth and an adhesive discharging opening is formed in the upper part, the blockage of the adhesive path can be effectively avoided; the service life of the mixer can be greatly prolonged; moreover, the structure is simple; and the use is convenient.

Description

technical field [0001] The invention relates to a device for evenly stirring and mixing a two-component adhesive according to a certain ratio, and is especially suitable for filling or dispensing fast-drying adhesives with good fluidity. The present invention is a divisional application of Chinese patent application CN2018116498903. Background technique [0002] Existing two-component sizing equipment includes pneumatic or electric spraying machines, glue pouring machines, glue pouring machines, glue dispensers, glue guns, etc. Generally, gear pumps, air pumps or electronic balances are used to adjust the volume ratio or mass ratio. The glue of the components is mixed through a static mixing tube or a dynamic agitator and flows out from the glue outlet. It is suitable for two-component adhesives with slower reaction and better fluidity. However, due to the dense helical channel for cutting and mixing glue in the static mixing tube, the lumen is narrow, tortuous, and the sur...

AI Technical Summary

Problems solved by technology

However, due to the dense helical channel for cutting and mixing glue in the static mixing tube, the lumen is narrow, tortuous, and the surface area is large. For intermittent glue, especially quick-drying glue, it is very easy to cause the enrichment of cured products, which affects Glue flow rate and mixing effect will eventually cause blockage, and frequent replacement of static mixing tubes not only affects work efficiency, wastes rubber, and the cost of tube replacement is unbearable, but also affects environmental protection

The conventional dynamic agitator uses a motor to drive the paddle to mix the rubber in a finger-sized mixing dish. For the same reason, the paddle and the mixing dish will continue to adhere and deposit with the increase in use time and frequency, and some will start to solidify. The residual glue then causes clogging

In addition, the existence of the agitator in the mixing container affects the use of glue, and the conventional lifting agitator has a complicated structure and high cost

These problems have seriously affected the assembly line operation of the factory and affected the popularization and application of new environmentally friendly and quick-drying AB glue.
