Technical Field

The invention relates to the field of part machining, in particular to a material conveying nozzle part and a numerical control machining method thereof.

Background

The material filling machine is a high and new technology filling equipment integrating microcomputer programmable control, photoelectric sensing and pneumatic execution. The machine is specially used for integrated high and new technology filling equipment. Can be used in foods, such as: filling edible liquid such as white spirit, soy sauce, vinegar, seasonings, vegetable oil, syrup, mineral water and pesticide chemical liquid. The filling is precise, has no air bubble and no water leakage, and is suitable for filling various bottle shapes (including special-shaped bottles).

When the material filling shipment in with the storage tank, need through pipeline and pump pressure with the material in into miniature container, when filling volatility is stronger, and the sharp material of taste, need nozzle and container close looks butt joint tightly, avoid leaking and volatilizing.

However, such operation brings about a great problem, when the nozzle is tightly jointed and butted with the container, along with the filling of liquid, the pressure in the container is increased, but the pressure can not be released, if the vent hole is simply formed above the container, volatile materials can overflow along with the vent hole, and the problem can not be solved fundamentally.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provide a material conveying nozzle part which can avoid the leakage of volatile substances and does not influence the pressure relief of a container and a numerical control processing method thereof.

The purpose of the invention can be realized by the following technical scheme:

a material conveying nozzle part is provided with a material conveying opening and at least one vent hole which are mutually independent;

the material conveying port is connected with the material storage tank through a material conveying pipeline, and the vent hole is connected with the tail gas treatment device through an exhaust pipe;

during filling, the material conveying opening is abutted against the material inlet on the container, and the vent hole is abutted against the air outlet on the container.

Thus, it is understood that the present invention integrates the functions of feeding and exhausting into one component to avoid the leakage of volatile substances without affecting the pressure release of the container, and the exhausted gas is not directly introduced into the atmosphere but is orderly treated by the component.

Furthermore, one side of the material conveying opening, which is close to the container, is provided with an outward flange. The contact area of the material conveying opening and the material inlet can be increased through the outward flanging, and the outward flanging can also be isolated from the vent hole, so that real gas-liquid isolation is formed.

Further, the height of the outward flanging is 40-60% of the inner diameter of the material conveying port.

Furthermore, a guide pipe is arranged on one side of the material conveying opening, which is far away from the container. The conduit helps to further convey the material in the storage tank to the container, and avoids volatilization due to midway leakage.

Furthermore, the length of the conduit is 2-3 times of the inner diameter of the material conveying opening.

Furthermore, a sleeve matched with the length of the guide pipe is arranged on the periphery of the part. The sleeve and the guide pipe enclose an independent air chamber, so that the materials can not flow into the container from the vent hole during conveying, and the gas in the vent hole can not interfere the material input process.

Further, a groove is arranged around the vent hole. The groove can also increase the contact area between the vent hole and the air outlet and can be further isolated from the material conveying opening to form further gas-liquid isolation.

Further, the depth of the groove is 40-60% of the inner diameter of the vent hole.

Furthermore, one side of the part, which is close to the container, is provided with at least two bolt holes, and the container is also provided with bolts matched with the bolt holes. When the materials are input, the bolt holes are matched with the bolts, so that the alignment accuracy of each counter part is ensured, the connection strength of the nozzle part and the container is increased, and the sliding is avoided.

A numerical control machining method for the material conveying nozzle part uses UG10.0 software to carry out three-dimensional modeling, designs a feed path, simulates numerical control machining on a turning and milling composite machining center, and comprises the following steps:

opening UG10.0 software, building a model for modeling, drawing a planar sketch, and obtaining a three-dimensional model through rotation characteristics;

making a two-dimensional engineering drawing, marking the process dimensions (including dimension tolerance marking, form and position tolerance marking, roughness marking and technical requirement marking) in detail,

making the technological specification and the processing technology of the parts,

the three-jaw chuck is used for clamping one end (set as the end B) firstly, turning the end A, drilling, milling threads, turning the other end (set as the end A) and machining the end B, and only needs to disassemble and clamp once in the process of finishing part machining, so that machining errors are greatly reduced.

The method is carried out by two layers of rough machining and finish machining.

Compared with the prior art, the invention has the following advantages:

(1) the invention integrates the feeding and exhausting functions into one part, thereby avoiding the leakage of volatile substances, having no influence on the pressure relief of the container, leading the exhausted gas not to be directly in the atmospheric environment, but to be orderly treated by the guide of the part;

(2) according to the invention, the contact area between the material conveying opening and the material inlet can be increased by the outward flanging, and the contact area between the vent hole and the air outlet can be increased by the groove, so that further gas-liquid isolation is formed;

(3) the numerical control machining process reduces the cutter abrasion, improves the part precision, reduces the error and has beautiful outer surface process by balancing the cutting load.
