Low noise and long service life stable glue dispenser with buffer structure

Abstract

The invention discloses a low noise and long service life stable glue dispenser with a buffer structure. The glue dispenser comprises a main body and an ejector rod, wherein the main body comprises afirst chamber above, a second chamber below and a third chamber connecting the first chamber and the second chamber, and the third chamber communicates to external glue supply; the ejector rod penetrates the first chamber, the second chamber and the third chamber successively and extends outside the lower part of the main body, the upper part of the ejector rod comprises a seal ring part in clearance fit to the side wall of the first chamber, the seal ring part divides the first chamber into a first sub chamber above and a second sub chamber below, the second sub chamber communicates to external gas supply, and a longitudinal spring is arranged in the first sub chamber. The buffer structure is arranged on the upper part of the ejector rod for buffering collision of the ejector rod and thefirst chamber longitudinally.

Description

technical field [0001] The invention belongs to the application field of industrial glue, and in particular relates to a low-noise, long-life and stable glue dispensing machine provided with a buffer structure. Background technique [0002] Glue dispensing machine, also known as glue applicator, glue dispenser, glue machine, glue pouring machine, etc., specializes in controlling fluid. And the automatic machine that drips and coats the fluid on the surface of the product or inside the product can realize three-dimensional and four-dimensional path dispensing, precise positioning, precise glue control, no wire drawing, no glue leakage, and no glue dripping. The glue dispenser is mainly used for accurate pointing, injecting, coating, and dripping of glue, paint and other liquids in the product process to the precise position of each product, and can be used to achieve dots, lines, circles or arcs. During the dispensing process of the automatic dispensing machine, common probl...

AI Technical Summary

Problems solved by technology

During the dispensing process of the automatic dispensing machine, there are common problems such as clogging of the glue nozzle, dripping of the glue valve, and bubbles in the fluid.

[0003] The action mechanism in the dispensing machine will emit noise. On the one hand, the vibration will affect the stability of the glue, and on the other hand, it will increase the loss of the entire structure and reduce the durability. In addition, the noise will also affect the surrounding equipment or personnel.
