A can feeding mechanism of under-cover filling machine

Abstract

An under-cap filling machine tank entry mechanism provides a brand-new fully automatic linear three-head under-cap filling machine with high degree of automation, high production efficiency, low cost, stable and reliable performance, and convenient and quick maintenance. It includes side booster, servo screw linear feed mechanism, left slide plate for tank entry, barrier 1, middle slide plate, barrier 3, guide plate assembly for tank discharge, right slide plate for tank discharge and barrier 2. The present invention can automatically complete the filling of the aerosol can with the refrigerant valve cover on it. During work, the top of the aerosol can is provided with a filling machine head under the cover. For example, three filling machine heads under the cover are provided. If there is no aerosol can at the station below the machine head of the lower filling machine, the rotation of the servo motor will drive the can feeding screw to rotate three times, and the aerosol can will slide on the sliding plate from left to right for a distance of three times the pitch, and this At the same time, the stepping motor of the side booster device rotates to drive the belt to rotate synchronously to help the aerosol cans enter the canning screw, avoiding canister jamming and improving the reliability of canning.

Description

technical field [0001] The invention relates to an aerosol filling machine, in particular to a can feeding mechanism of the filling machine for producing special refrigerant for automobile air conditioners. Background technique [0002] Refrigerant aerosol products for automobile air conditioners are classified as aerosols, but they are quite different from ordinary aerosols. Although its aerosol cans also use two-piece cans, three-piece cans or aluminum cans (single-piece cans), the pressure resistance requirements are generally slightly higher than ordinary aerosol cans. The valve cover adopts 1″ standard refrigerant special valve cover, which is different from the valve core of ordinary aerosol valves. Fill the liquid on the machine, put the valve on the sealing machine to seal, and then fill the propellant (such as LPG, DME, R-134a and other liquefied gas) on the inflator. The filling of the propellant is filled from the valve core into the aerosol tank The filling can...

AI Technical Summary

Problems solved by technology

At present, there are only a few companies in Europe and the United States that can produce fully automatic under-cap filling machines, and the price is expensive, and the equipment maintenance costs are high and the cycle is long.

[0007] In short, the existing filling machine under the cover can no longer meet the needs of the production and processing of special refrigerant aerosol for automobile air conditioners, and the efficiency of entering the tank is low, which increases labor time and cost.
