Industrially-used glue-applying device

Abstract

The invention relates to a glue-applying device, which comprises a glue storage tank (1), a hose (4) and an applying head (6), wherein the hose (4) is communicated with the glue storage tank (1) and the applying head (6). The glue-applying device is characterized in that the applying head (6) comprises a main valve (61), a spring seat I (62) and a glue-outlet body (67); the upper end of the spring seat I (62) is in threaded connection with the main valve (61) and is communicated with the main valve (61), and the lower end of the spring seat I (62) is in threaded connection with the glue-outlet body (67); a rolling ball (68), an ejection block (66) and a spiral spring I (63) are sequentially installed inside the glue-outlet body (67) from bottom to top; the upper end of the spiral spring I (63) supports against the spring seat I (62), and the lower end of the spiral spring I (63) supports against the ejection block (66); and the diameter of a glue outlet (671) arranged at the bottom of the glue-outlet body is slightly smaller than that of the rolling ball (68). The glue-applying device provided by the invention can be suitable for glue solutions with different viscosities, the consistency of coating width is good, the coating efficiency is high, the glue solutions are saved, and the volatilization of harmful gases can be reduced.

Description

Technical field: [0001] The invention relates to a gluing device used in the processing industry. Background technique: [0002] Adhesive technology is widely used in processing industries such as shoe and leather goods as well as packaging boxes. The traditional way is that the worker holds the glue brush to dip the glue solution from the open glue container, paints it on the parts to be bonded, and then completes the bonding through the pressing process. The operation mode of this hand-held glue brush has the following defects: 1. It is difficult to control the amount of glue dipped by hand, and the thickness of the glue is uneven, which affects the bonding strength of the product; 2. The glue is easy to drip on the bonded surface. In addition, it affects the bonding quality of the product, and the waste of glue is large; 3. Because the bristles are soft, it is difficult to control the width consistency of the brush; 4. Because the glue needs to be dipped from time to tim...
