Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.
Example 1
As shown in fig. 1; a polyurethane foam gap filler white black material filling nozzle comprises:
the device comprises a fixed shell 1, wherein a feeding hole 12 is formed in the fixed shell 1;
the material injection pipe 2 is fixedly arranged at the lower part of the fixed shell 1, one end of the material injection pipe 2 extends into the fixed shell 1 and is provided with a sealed hopper opening 13, and the other end of the material injection pipe 2 extends out of the fixed shell 1;
the outside slip ring cover of the notes material pipe 2 that is located fixed casing 1 outside has compression cover 14, be equipped with extrusion spring 15 between compression cover 14 and the fixed casing 1, install ejector pin 16 on the compression cover 14, ejector pin 16 inserts to fixed casing 1 inside along annotating the slip of 2 axis directions of material pipe, install seal receptacle 17 on the ejector pin 16, seal receptacle 17 is located fixed casing 1 inside, the cover is on annotating material pipe 2, install support frame 18 on the seal receptacle 17, be fixed with sealing plug 19 on the support frame 18, sealing plug 19 is located directly over sealed fill mouth 13.
A polyurethane foam gap filler white black material filling nozzle, the working principle is as follows:
when the tank body needs to be filled, the fixed shell 1 drives the material filling pipe 2 to move downwards, the material filling pipe 2 is inserted into the tank body, the compression sleeve 14 outside the material filling pipe 2 is limited by the port of the tank body to move upwards along the material filling pipe 2, in the moving process, the ejector rod 16 is pushed upwards, the ejector rod 16 pushes the sealing seat 17, the sealing seat 17 drives the support frame 18 to move, so that the sealing plug 19 on the support frame 18 is separated from the sealing hopper port 13, at the moment, raw materials entering the fixed shell 1 from the material filling pipe 2 can enter the tank body through the material filling pipe 12, after the material filling is completed, the fixed shell 1 moves upwards, so that the material filling pipe 2 is drawn out of the tank body, after the material filling pipe 2 is drawn out, the compression sleeve 14 pulls the ejector rod 16 to move towards the end part outside the material filling pipe 2 under the action of the extrusion spring 15, so that the sealing plug 19 blocks the sealing hopper port 13, the spray head can discharge materials only when being inserted into the tank body, the interior of the spray head is automatically sealed after the tank body is pulled out, and the phenomenon that the spray head leaks after being pulled out of the tank body is effectively prevented.
