Embodiment 1

[0025] Example 1, such as figure 1 , figure 2 , image 3 As shown, this embodiment is a combined hot-melt adhesive nozzle, which is mainly composed of a nozzle body 1, an adapter plate 2, and an air pressure plate 3. The adapter plate 2 is close to the nozzle body 1 from below. On the contact surface of the plate 2 and the nozzle body 1, the nozzle body 1 is provided with a glue storage tank 5, which is a groove arranged on the side of the nozzle body 1. When the adapter plate 2 is close, it becomes a sealed groove. groove. This sealed groove is connected with the glue path of the glue sprayer, and the glue sprayer can control the hot melt glue nozzle 4 connected with the glue storage tank 5 by controlling the pressure and temperature of the hot melt glue in the glue path, mainly Glue volume control, the hot melt glue nozzle 4 protrudes from the lower side of the nozzle body 1 and communicates with the glue storage tank 5. On the outside of the adapter plate 2 correspondin...

Abstract

A modular hot-melt adhesive spray head, comprising a spray head body (1), and further comprising an adapter plate (2) and a gas pressure plate (3), the adapter plate (2) abutting the spray head body (1) from the side, covering the opening of an adhesive reservoir (5) such that the adhesive reservoir (5) is a closed reservoir; the top side of the gas pressure plate (3) abutting against the underside of the spray head body (1) such that a gas storage reservoir (6) is a closed reservoir. The hot-melt adhesive spray head is divided into three parts: the spray head body (1), the adapter plate (2), and the gas pressure plate (3); Separating the gas pressure plate (3) and the spray head body (1) allows for the gas nozzle (8) to be separate from the hot-melt adhesive nozzle (4); on the gas pressure plate (3), the gas nozzle (8) can be conveniently and thoroughly cleaned from the two sides of the gas nozzle (8), thereby increasing service life.

Description

technical field [0001] The invention relates to the technical field of hot-melt adhesives, in particular to a spray head of a hot-melt adhesive spraying machine. In the hot-melt adhesive spray head, a hot-melt adhesive nozzle and an air nozzle are separated to form a combined hot-melt adhesive spray head. Background technique [0002] The commonly used AB glue and super glue are not environmentally friendly. Therefore, employees use hot melt adhesive to bond the adherend. Generally, hot melt adhesive is used to bond some non-woven fabrics. At present, in the production process of sanitary napkins, diapers, etc. It is made of hot melt adhesive. [0003] Hot melt adhesive is a kind of plastic adhesive. Its physical state changes with temperature within a certain temperature range, but its chemical properties remain unchanged. It is non-toxic and tasteless. It is an environmentally friendly chemical adhesive. Bonding is to use a hot-melt glue machine to melt the hot-melt glue ...
