Soy sauce filling machine

Abstract

The invention discloses a soy sauce filling machine; a first magnet is fixed on an upper end of a guide rod; a cover plate is engaged with an upper end of a steam-return pipe and can cover an opening of the steam-return pipe; a second magnet is fixed at one side of the cover plate near the guide rod; the facing surfaces of the first magnet and the second magnet have the same magnetism; when the guide rod is lifted to the highest position, the first magnet and the second magnet are approximately on the same horizontal line. The invention can control the opening or closing of the channel between a material cylinder and external air by the interaction between the first magnet and the second magnet, realizes no vacuum pumping when no bottle is provided, ensures the filling quality, and has a simple structure.

Description

technical field [0001] The invention relates to a filling machine, in particular to a soy sauce filling machine. Background technique [0002] In order to improve production efficiency, soy sauce filling machine (a kind of vacuum filling machine) is generally used to fill soy sauce on the soy sauce production line. During work, the material tank is evacuated by a vacuum device to keep the pressure in the material tank at - 0.01~-0.025MPa, when the empty bottle enters the filling area, the bottle holding device lifts the empty bottle and pre-centers it through the centering device, so that the bottle supporting cylinder of the bottle holding device will hold the bottle and the guide bottle of the centering device The block and the filling valve are pressed together in pairs. At this time, the bottle mouth and the valve mouth of the filling valve are sealed butt joint, the discharge port of the filling valve is opened, and the bottle is vacuumed through the return air pipe; A...

Problems solved by technology

[0003] But the existing soy sauce filling machine still has deficiencies, such as: 1. In the course of work, it is unavoidable that the empty bottle cannot reach the bottle supporting cylinder smoothly. It is impossible to tell whether the bottle is in place, and the vacuuming action on the bottle is still carried out, which will cause the internal pressure value of the material tank to deviate from the predetermined range and affect the subsequent filling quality; of course, the Chinese patent No. "ZL 00239420. A mechanical filling valve for pure draft beer, on which there is a "no-bottle, no-vacuum part" but the structure of the "no-bottle, no-vacuum part" is relatively complicated, and it is not suitable for the filling production requirements of soy sauce

2. In order to enable the filling machine to fill bottles of different heights, the filling machine is equipped with a lifting device that can control the lifting of the material cylinder, filling valve and centering device, but the lifting device of the prior art filling machine mainly The motor drives the chain to drive the lifting of the material cylinder, filling valve and centering device. It is difficult to accurately control the lifting displacement and the structure is complicated.

3. In the process of filling soy sauce, due to the impact of the soy sauce's own weight, more foam will often be produced, resulting in inaccurate filling accuracy, and even the soy sauce overflows from the bottle due to foaming
