Description

Technical Field

[0001] The utility model relates to the technical field of glue applicators, in particular to a glue replenishing device and a glue applicator thereof. Background Art

[0002] A glue applicator, also known as a coating machine, a glue scraping machine, an automatic glue spraying machine, etc., is mainly a mechanical device used to apply liquid glue on the surface of textiles, paper boxes or leather.

[0003] When the glue in the existing glue applicator is used up, automatic glue replenishment is required. Here, automatic glue replenishment is usually achieved through a liquid level sensor cooperating with a controller. The liquid level sensor detects the liquid level of the glue in the glue tank. When the liquid level reaches the threshold, an electrical signal is transmitted to the controller, and the controller controls the glue delivery pump to replenish glue into the glue tank. Among them, the detection accuracy of the remaining glue liquid level by the liquid level sensor is relatively important.

[0004] The difference between glue and other liquids with stronger fluidity is that glue has viscosity and poor fluidity. This leads to more glue slowly flowing down and adhering to the inner wall of the glue tank. The traditional contact liquid level sensor may not calculate the glue adhering to the inner wall of the glue tank and flowing down when detecting the current liquid level, resulting in poor liquid level detection accuracy, increasing the glue replenishment frequency. The glue adhering to the inner wall of the glue tank for a long time is prone to deterioration, and the deteriorated glue is partially mixed into the newly replenished glue, affecting the glue application quality. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a glue replenishing device and a glue applicator thereof. The device regularly scrapes the glue adhering to the inner wall of the glue tank downward through a glue scraping mechanism on the inner wall of the glue tank. After the scraped glue accumulates, it falls to the lower end of the inner cavity of the glue tank due to its own weight, avoiding the problem that the glue adhering to the inner wall of the glue tank is prone to deterioration after a long time. At the same time, after scraping the glue adhering to the inner wall of the glue tank, an ultrasonic liquid level sensor is used to detect the liquid level from above, with higher liquid level detection accuracy and reduced glue replenishment frequency.
