Embodiment 1

[0030] like figure 1 As shown, the glue gun includes a gun body 1 , a nozzle 2 , a wind cap 3 , a thimble 4 and a drive source 5 .

[0031] The gun body 1 has a glue feeding channel 1a and an air inlet channel 1b.

[0032] A glue outlet channel 2a is opened in the nozzle 2, and one port of the glue outlet channel 2a is a glue outlet 2b.

[0033] The nozzle 2 is fixed on the gun body 1 by threads, and the other port of the glue outlet channel 2a communicates with the glue inlet channel 1a.

[0034] The thimble 4 is pierced in the gun body 1, and the head of the thimble 4 is conical, which is a pointed structure. The thimble 4 passes through the glue outlet channel 2a and the head of the thimble 4 passes through the glue outlet 2b. The outer surface of the head of the thimble 4 can abut against the inner surface of the small glue outlet 2b and form a seal, and then block the small glue outlet 2b, that is, close the small glue outlet 2b. The axial movement of the thimble 4 le...

Embodiment 2

[0048] The structure and principle of this embodiment are basically the same as those of the first embodiment, except that the spiral passage 12 only includes several helical grooves on the inner surface of the wind cap 3 .

Embodiment 3

[0050] The structure and principle of this embodiment are basically the same as those of the first embodiment, except that the spiral channel 12 only includes several spiral grooves on the outer surface of the nozzle 2 .

Abstract

The invention provides a glue gun and belongs to the technical field of operation. The problem that the viscidity of glue is reduced as fine particles are formed in a glue-spraying process of the current glue gun is solved. The glue gun comprises a gun body, a spraying nozzle, an air cap and a plurality of spiral passages, wherein the gun body is provided with a glue-inlet passage and an air-inlet passage; the spraying nozzle is fixedly connected with the spraying nozzle; a glue-outlet passage with a small glue-outlet opening is arranged in the spraying nozzle and is communicated with the glue-inlet passage; a spraying opening is formed in the air cap; the air cap is sleeved on the spraying nozzle and is fixedly connected with the gun body; the small glue-outlet opening of the spraying nozzle and the spraying opening of the air cap are oppositely arranged; a converging clearance is formed between the outer side surface of the spraying nozzle and the inner side surface of the spraying opening of the air cap; the spiral passages are communicated with the converging clearance and the air-inlet passage. Glue sprayed out by the glue gun is silk-shaped, so that the organizing structure of the glue is prevented from being damaged, the glue is prevented from being cured, the silk-shaped glue is coated on the surface of an object, the contact surface between the glue and the object is increased, the viscidity is further improved, and the viscidity of the glue is effectively guaranteed.

Description

technical field [0001] The invention belongs to the technical field of operations, and relates to a spraying device, in particular to a glue spray gun. Background technique [0002] Glue bonding is a commonly used connection method in many products, such as between the upper and sole of shoes, diapers or sanitary napkins and packaging bags, etc. [0003] Most of the existing enterprises still use manual gluing or rolling gluing with the help of mechanical rollers. Manual brushing and gluing methods have the problems of time-consuming and laborious, serious waste of glue and uneven quality. Although the gluing device with the help of rollers is more efficient than manual gluing and gluing, and reduces the labor intensity of workers, there are still problems such as low efficiency, glue cost and uneven quality. [0004] In order to solve the above-mentioned problems, someone has proposed a kind of atomizing jet coating gluing device, and is recorded in Chinese patent documen...
