Description
Technical Field
The utility model relates to the technical field of pneumatic injection valve piston reset force transmission, in particular to a pneumatic injection valve piston reset force transmission structure.
Background
The pneumatic injection valve is used as a high-precision glue valve frequently used in the glue dispensing industry, is widely applied to glue dispensing production processes in various industries, and the movement and stress conditions of a core component piston thimble in the pneumatic injection valve directly determine the performance and service life of the glue valve, so that the injection force and the precision of the piezoelectric valve injection valve are greatly influenced.
The existing piston thimble movement is usually directly driven by high-pressure gas, and the quick response time and the uniform stress surface are difficult to ensure, so that the performance of the pneumatic injection valve is uneven, and the dispensing precision and the service life are affected.
Therefore, a convenient and quick structure for resetting and transferring force of the piston is provided.
Disclosure of Invention
The utility model aims to solve the defects that the conventional piston thimble movement is usually direct driven by high-pressure gas, and the quick response time and the uniform stress surface are difficult to ensure, so that the performance of a pneumatic injection valve is uneven and the dispensing precision and the service life are affected.
In order to achieve the above purpose, the present utility model adopts the following technical scheme:
the utility model provides a pneumatic injection valve piston power transmission structure that resets, includes the cylinder, be equipped with the sliding chamber in the cylinder, the thimble slide opening has been seted up to the bottom of cylinder, thimble slide opening and sliding chamber intercommunication, the fixed cylindric circle that is equipped with in top of cylinder, be equipped with the frisbee in the sliding chamber, compress tightly on the frisbee and have the spring.
Preferably, a piston thimble is arranged in the sliding cavity, and one end of the piston thimble and a sliding hole penetrating through the thimble are positioned below the bottom of the cylinder.
Preferably, one end of the spring passes through the cylindrical ring and is located above the cylinder.
Preferably, the top of cylinder is equipped with the top cap, and threaded connection has four fastening screw between top cap and the cylinder.
Compared with the prior art, the utility model has the advantages that:
the scheme is that the spring, the flying disc, the piston thimble and the cylinder are arranged, so that the pneumatic impact can be more effectively and evenly spread on the stress surface, and the force compressed by the spring is more effectively transferred to the piston.
The utility model has simple structure, reduces uneven stress caused by uneven air pressure impact, reduces impact error, prolongs the service life, improves the product performance and is convenient for people to use.

Detailed Description
The technical solutions of the present embodiment will be clearly and completely described below with reference to the drawings in the present embodiment, and it is apparent that the described embodiments are only some embodiments of the present embodiment, not all embodiments.
Referring to fig. 1-4, a pneumatic injection valve piston reset force transmission structure comprises a cylinder 4, wherein a sliding cavity is arranged in the cylinder 4, a thimble sliding hole is formed in the bottom of the cylinder 4 and communicated with the sliding cavity, a cylindrical ring is fixedly arranged at the top of the cylinder 4, a flying disc 2 is arranged in the sliding cavity, and a spring 1 is compressed on the flying disc 2.
In the embodiment, a piston thimble 3 is arranged in the sliding cavity, and one end of the piston thimble 3 is positioned below the bottom of the cylinder 4 through a thimble sliding hole.
In this embodiment, one end of the spring 1 passes through the cylindrical ring and is located above the cylinder 4.
In this embodiment, the top of cylinder 4 is equipped with the top cap, and threaded connection has four fastening screw between top cap and the cylinder 4.
In this embodiment, when the pneumatic injection valve piston reset force transmission structure is used, the spring 1 compresses the upper surface of the flying disc 2, and because the piston thimble 3 and the flying disc 2 are only in contact with each other at a point on the top, all the force of the spring 1 is transmitted through the point, and because the piston thimble 3 moves in the cylinder 4, the inner wall of the cylinder 4 has a guiding function, so that the impact function of most of the force guiding firing pin ensures the uniformity of downward movement, and the air guiding groove below the cylinder 4 guides the air to form an annular air hammer below, so that the high-pressure air is better and more uniformly utilized to directly drive the piston firing pin 3 to move upwards.
The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art will be able to apply equally to the technical solution of the present utility model and the inventive concept thereof, within the scope of the present utility model.
