High pressure mixing injection nozzle

Abstract

The invention provides a high-pressure mixed glue injection nozzle which comprises a glue injection pipe, a spray nozzle body and a heating part. The glue injection pipe comprises a glue injection input pipe and a glue injection output pipe. The spray nozzle body comprises a spray nozzle body housing, a spray head and a glue injection cavity. The spray nozzle body housing communicates with the glue injection output pipe through a glue injection spray pipe. The glue injection cavity is formed in the spray nozzle body housing, and comprises a conical cavity, a semi-kidney cavity and a semi-elliptical cavity, which are arranged from top to bottom from inside to outside in sequence. The spray head communicates with the bottom of the spray nozzle body housing, and takes the shape of a hollow gyroscope. Spray cavities are uniformly formed in the spray head, and are mounted in the axial direction of the spray head. A cyclone core is mounted on the inner side of each spray cavity. Spray holes are formed in the outer side of each spray cavity. The heating part comprises a heating plate and heating columns. The heating plate clings to the surface of the glue injection pipe. The heating columns are distributed on the inner walls of the glue injection input pipe and the glue injection output pipe in an arraying manner. By adoption of the high-pressure mixed glue injection nozzle, mixture of glue and a mixture can be effectively ensured, and the gluing quality is ensured when the adhesion of glue to the inner wall is reduced to the greatest degree.

Description

technical field [0001] The invention belongs to the field of spraying equipment, and in particular relates to a high-pressure mixing glue injection nozzle. Background technique [0002] Polyurethane boards generally have a multi-layer structure, and glue needs to be sprayed between layers to stick them together. If spraying is done manually, uniform spraying can not be guaranteed, and it is time-consuming and laborious. Therefore, mechanical equipment is usually used to drive the gluing device for gluing. However, most of the existing gluing devices are made of metal pipes through perforation, which are easy to block. When blockage occurs, not only the spraying efficiency will be affected, but also the spraying efficiency will be reduced. [0003] Therefore, in order to solve the above problems, it is an urgent problem for those skilled in the art to develop a device that is not easy to block and can apply glue evenly. Contents of the invention [0004] In order to solve ...

Problems solved by technology

[0002] Polyurethane boards generally have a multi-layer structure, and glue needs to be sprayed between the layers for sticking. If spraying is done manually, it can neither guarantee uniform spraying, but also takes time and effort. Therefore, mechanical equipment is usually used to drive the gluing device for gluing.

However, most of the existing gluing devices are made of metal pipes through perforation, which are easy to block. When blockage occurs, it will not only affect the spraying efficiency, but also reduce the spraying efficiency
