Filling speed-controllable filling device

Abstract

The invention discloses a filling speed-controllable filling device which comprises a liquid storage cylinder and a filling valve, wherein a material in the liquid storage cylinder has back pressure, a feeding passage and an exhaust passage are arranged in the filling valve, and the exhaust passage is divided into at least three branch passages including a first passage, a second passage and a third passage, wherein the aperture sizes of the first passage and the second passage are different, both the first passage and the second passage are communicated with a pressure retaining air chamber, and the air pressure value of the pressure retaining air chamber is balanced with the back pressure value in the liquid storage cylinder; the third passage is communicated with an exhaust chamber, and atmospheric normal pressure is kept in the exhaust chamber; and air valves for controlling the on-off of the first passage, the second passage and the third passage are respectively correspondingly arranged in the first passage, the second passage and the third passage. The air valve of the corresponding the branch passage is opened as required to control the airflow speed in the exhaust passage so as to realize the real-time control for the filling speed in the filling process, thereby not only effectively reducing a foam phenomenon in the filling process, but also enhancing the filling quality.

Description

technical field [0001] The invention relates to the technical field of liquid filling equipment, in particular to a filling speed controllable filling device. 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 pressurized filling ...

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.
