Detailed Description
The features and principles of the present invention will be described in detail below with reference to the accompanying drawings, and the illustrated embodiments are only for explaining the present invention, and do not limit the scope of the present invention.
As shown in figure 1, the novel spray gun head comprises a gun barrel 1, a transition pipe 2 and a gun nozzle 3, wherein the gun barrel 1 is connected with one end of the transition pipe 2 and is sealed through a sealing ring 5, and the gun nozzle 3 is connected with the other end of the transition pipe 2 and is sealed through the sealing ring 5. A glue spraying channel is arranged in the gun nozzle 3, and the top of the glue spraying channel is a glue spraying opening with a round opening.
As shown in fig. 9, the transition pipe 2 is a circular pipe with upper and lower inner walls provided with a sealing ring mounting groove 6, and the inner wall of the transition pipe 2 is provided with an anticorrosive smooth layer, so that on one hand, corrosion is prevented, and on the other hand, cleaning is convenient.
Still including flow equalizing body 4, flow equalizing body 4 installs in transition pipe 2, is located between barrel 1 and the rifle mouth 3, and 4 barrel 1 of flow equalizing body have certain distance.
As shown in fig. 7 and 8, the flow equalizing body 4 includes a column 7, a conical head 8 and a flow equalizing sheet 9, the column 7 is a cylinder, the conical head 8 and the column 7 are integrated, a plurality of flow equalizing sheets 9 arranged at intervals are uniformly arranged on the outer side surface of the column 7 along the axial direction, and one end of the flow equalizing sheet 9 close to the gun nozzle 3 is an inclined surface. The flow equalizing sheets 9 are straight flow equalizing sheets 9 which are parallel to each other or the flow equalizing sheets 9 are spiral flow equalizing sheets 9 with the same trend.
