Automatic heating glue sprayer

Abstract

The invention belongs to the technical field of cigarette paper glue spraying, and particularly relates to an automatic heating glue sprayer. The automatic heating glue sprayer comprises a valve needle base, a valve body and a valve needle, wherein a platinum resistor, a heater and a temperature controller are further arranged in the valve needle base, a needle head base and a needle head are arranged at the end, away from the valve body, of the valve needle base, the valve body is fixedly connected with the valve needle base through an M4 screw, an upper gland is arranged at the end, away from the valve needle base, of the valve body, the valve needle is arranged in the middle of the valve needle base and the middle of the valve body in a transverse-penetrating mode, a spring is connectedto the end, away from the valve needle base, of the valve needle, the same sides of the valve needle seat and the valve body each are provided with a round through hole, the round through holes are used for being connected with a glue supply joint and an air supply joint correspondingly, the air supply joint is connected with an air source, and the platinum resistor, the heater and the temperature controller are connected with a power supply. The automatic heating glue sprayer has the beneficial effects that the possibility of glue spraying interruption is reduced, the waste rate of resourcesis reduced, and the latex quality and the working efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of glue spraying for cigarette paper, in particular to an automatic heating glue sprayer. Background technique [0002] During the production process of the coiling unit, the latex in the rubber barrel is transported to the glue sprayer by gravity or the action of the glue pump, and the nozzle of the glue sprayer sprays the latex continuously on the cigarette paper. The latex used must maintain good fluidity, and must not contain impurities, agglomerates, etc., otherwise it will block the nozzle and cause glue spraying to be interrupted. [0003] The latex used is water-based glue. Due to the loss of water, the latex will solidify and form agglomerates. Before entering the glue sprayer, the agglomerates need to be filtered out to avoid blocking the nozzle; although some coilers are equipped with latex filter devices , but there are problems such as small filtration area, inconvenient cleaning, and difficult...

The latex used must maintain good fluidity, and must not contain impurities, agglomerates, etc., otherwise it will block the nozzle and cause glue spraying to be interrupted

[0003] The latex used is water-based glue. Due to the loss of water, the latex will solidify and form agglomerates. Before entering the glue sprayer, the agglomerates need to be filtered out to avoid blocking the nozzle; although some coilers are equipped with latex filter devices , but there are problems such as small filtration area, inconvenient cleaning, and difficult elimination of bubbles in latex after cleaning, which will still cause production interruption and affect production progress
