Needle tube type filling machine and filling method thereof

Abstract

The invention discloses a needle tube type filling machine and a filling method thereof. The needle tube type filling machine comprises a liquid feeding device, a perfusion needle tube connected with the liquid feeding device and capable of extending into a bottle, and an exhaust passage capable of being hermetically communicated with a gap between the outer wall surface of the perfusion needle tube and the inner wall surface of an opening of the bottle, wherein a speed control device capable controlling the exhaust velocity of the needle tube type filling machine is arranged in the exhaust passage. The needle tube type filling machine is used for performing perfusion by extending the needle tube into the bottle so that the air in the bottle can be exhausted along the periphery of the needle tube, then the speed control device is used for controlling the air exhaust velocity to realize the effective control of the perfusion speed to ensure that the speed control during the perfusion is possible, and thus, a special perfusion mode of slow filling-quick filling-slow filling and the like is formed according to needs, and subsequently, foaming phenomena in the process of the perfusioncan be effectively reduced and the filling quality is improved.

Description

technical field [0001] The invention relates to the technical field of liquid filling equipment, in particular to a needle tube filling machine and a filling method thereof. Background technique [0002] The filling machine is a kind of mechanical equipment used to fill various filling materials such as gas-containing liquid, non-gas liquid and paste into various packaging containers such as bottles, cans, boxes, barrels or bags. Packing can not only improve labor productivity, reduce product loss, ensure packaging quality, but also reduce mutual pollution between the production environment and the materials to be packed. Therefore, the filling machine has been widely used in the automatic filling production of pharmaceutical, daily chemical, food and special industry factories. According to the filling principle, filling machines include vacuum filling machines, normal pressure filling machines, reverse pressure filling machines, negative pressure filling machines or press...

AI Technical Summary

Problems solved by technology

[0003] However, although the above-mentioned existing filling machine can realize the basic functions of its filling operation, it is found that there are still many deficiencies in its own structure and performance in actual use, and it cannot achieve the best use effect and work performance. efficacy

Its shortcomings are especially reflected in: during the filling process, the filling speed of the liquid cannot be precisely controlled and changed, so that foaming is easily generated, and the filling quality of the product cannot be guaranteed.
