A vacuum pumping nitrogen filling plugging device and production line

Abstract

The invention discloses a vacuumizing nitrogen feeding tamponade device which comprises a sleeve, wherein the sleeve comprises an outer shaft and an inner shaft; the outer shaft and the inner shaft are coaxial and can slide relatively; the outer shaft is connected with a first lifting gear; a seal joint matched with a bottle body in a sealing manner is arranged at the lower end of the outer shaft; the inner shaft is connected with a second lifting gear; an air passage is formed in the inner shaft; a plug absorbing base communicated with the air passage is arranged at the lower end of the inner shaft; A sealing assembly is arranged between the inner shaft and the outer shaft; a vacuumizing nitrogen feeding port is arranged on the side wall, positioned between the sealing assembly and the seal joint, of the outer shaft. Therefore, the vacuumizing nitrogen feeding tamponade device can form a small sealed space at the bottle opening, can accurately control the remaining oxygen through repeated operation of vacuumizing and nitrogen feeding, and immediately carries out the tamponade operation in the sealed space after nitrogen feeding, so that re-intervention of oxygen during the transporting process of bottle bodies can be avoided, the defective percentage and production cost are reduced, and the production efficiency is improved. The invention further discloses a vacuumizing nitrogen feeding tamponade production line.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a vacuum-pumping and nitrogen-filling plugging device and a production line. Background technique [0002] At present, the infusion preparations sold on the market are mainly plastic bottle infusion and glass bottle infusion. When filling nutritional and therapeutic liquids (such as amino acids, fat emulsions, etc.) that have strict requirements on oxygen content, precise control is required. The amount of residual oxygen in each infusion bottle. [0003] In the prior art, the filled infusion bottle needs to first enter the nitrogen filling station to fill the bottle mouth with nitrogen, discharge the oxygen in the bottle mouth, and then enter the corking station. The time is long, which reduces the production efficiency. More importantly, because the nitrogen filling and the plugging are carried out separately, the residual oxygen in the infusion bottle is difficult t...

Problems solved by technology

[0003] In the prior art, the filled infusion bottle needs to enter the nitrogen filling station to fill the mouth of the bottle with nitrogen, discharge the oxygen from the bottle mouth, and then enter the corking station. In this way, the interval between nitrogen filling and corking The time is long, which reduces the production efficiency. More importantly, because the nitrogen filling and the stopper are carried out separately, the residual oxygen in the infusion bottle is difficult to accurately control, which leads to an increase in the defective product rate and increases the production cost.
