Further, the second ejector pin acts on the nozzle seal gasket in the discharge nozzle.

Furthermore, a spring is arranged in the feeding cylinder and acts on the second piston.

To sum up, the utility model discloses possess following advantage:

the utility model discloses overall structure is succinct reasonable, and sealed effect is excellent, and sealed cross-section is the thimble cross-section, and sealed face is little, and the material intracavity portion reaction is little, and valve seal is stable, and more, the cylinder is dismantled conveniently, breaks down easily to be maintained.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

The invention will be further described with reference to the following drawings and examples:

example 1:

the utility model provides a point gum machine mixes first structure, as shown in figure 1, including mixing first pedestal 1 and independent connection at the circulation cylinder 2 and the feed cylinder 3 on mixing first pedestal 1, it is specific, circulation cylinder 2 and feed cylinder 3 are all fixed through bolt and mixing first pedestal to make things convenient for the dismouting.

Be equipped with charge-in pipeline 11, feed back pipeline 12, connecting tube 13 and ejection of compact pipeline 14 in the mixing head pedestal 1, on the position relation, charge-in pipeline 11 is parallel with feed back pipeline 12, and charge-in pipeline 11 communicates connecting tube 13, ejection of compact pipeline 14 perpendicularly to the feeding can directly reach ejection of compact pipeline in the shortest stroke.

With reference to fig. 1, the mixing head base 1 is provided with a discharge nozzle 4 communicated with the discharge pipe 14, a first piston 21 in the circulating cylinder 2 is connected to a first ejector pin 22 for sealing the return pipe 12, and specifically, the first ejector pin 22 acts on a return gasket in a material cavity formed by the connecting pipe 13 and the return pipe 12.

And a second piston 31 in the feeding cylinder 3 is connected to a second thimble 32 for closing the discharge nozzle 4, in particular, the second thimble 32 acts on the nozzle packing 6 in the discharge nozzle 4.

In the sealing arrangement of the whole cylinder and the material cavity, a sealing structure is formed in the circulating cylinder 2 through a first rubber ring 23 and a first framework oil seal 24 which are arranged in the front and back direction and the first ejector pin 22, and similarly, a sealing structure is formed in the feeding cylinder 3 through a second rubber ring 33 and a second framework oil seal 34 which are arranged in the front and back direction and the second ejector pin 32.

The cylinder forms through the mutually supporting of skeleton oil blanket, rubber circle and thimble three with the sealing in material chamber promptly to the contact surface at the seal structure of cylinder only is the thimble cross-section, when having reduced the valve switching greatly, to the influence of material intracavity pressure.

It is worth noting that a spring is arranged in the feeding cylinder 3 and acts on the second piston 31, so that self-sealing in the absence of an air source can be realized.

This structure will control the cylinder and independently come out, is connected with mixing head pedestal through the screw, has rubber circle and skeleton oil blanket to seal in the middle of material chamber and the cylinder, guarantees absolute airtight, and during the piston motion in the control cylinder, only the thimble is reciprocal at material intracavity portion, when having reduced the valve switching greatly, to the influence of material intracavity internal pressure.

And when the cylinder is controlled to act, the influence on the volume of the material cavity is reduced to the minimum, and the cylinder and the material cavity are isolated.

Furthermore, when the interior of the cleaning machine is cleaned, only the control cylinder needs to be detached, and the cleaning machine is convenient to clean.

To sum up, this scheme overall structure is succinct reasonable, and sealed effect is excellent, and sealed cross-section is thimble cross-section, and sealed face is little, and the material intracavity portion reaction is little, and valve seal is stable, and more, the cylinder is dismantled conveniently, breaks down easily the maintenance.
