Filling device for soy sauce filling machine

Abstract

The invention discloses a filling device for a soy sauce filling machine. The filling device comprises a filling valve and a centering apparatus, wherein the filling valve is mounted on a valve base and is connected to a material jar; the filling valve comprises a valve body and an air return pipe; a choke plug which is used for controlling the opening and closing of the discharging port of the valve body is arranged on the air return pipe; the air return pipe is composed of upper and lower sections; the central lines of the upper and lower sections are deviated from each other; and a flow-guiding block used for guiding the flow of the soy sauce is arranged on a part, which is inserted into a bottle, of the lower section. Compared with a flow-guiding mode by using an umbrella-shaped flange of the prior art, the filling device provided by the invention has the advantages that a horizontal distance between the external end of the flow-guiding block on the lower section of the eccentric air return pipe and the outer wall of the lower section is bigger, a corresponding flow-guiding channel is longer, the soy sauce can be more conveniently guided to flow toward the inner wall of the bottle and flow along the inner wall, the direct impact of the soy sauce on the bottom of the bottle or the soy sauce in the bottle is reduced, the generated foam is reduced and the filling quality is improved.

Description

technical field [0001] The invention relates to a filling device, in particular to a filling device of a soy sauce filling machine. Background technique [0002] In order to improve production efficiency, the soy sauce filling machine is generally used to fill the 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 When entering the filling area, the bottle holding device lifts up the empty bottle and pre-centers it through the centering device, so that the bottle holding cylinder of the bottle holding device presses the bottle, the centering device and the filling valve together in pairs, At this time, the mouth of the bottle and the valve mouth of the filling valve are sealed and docked, the discharge port of the filling valve is opened, and the bottle is evacuated through the air return pipe; It flows out from the outlet of the fillin...

AI Technical Summary

Problems solved by technology

[0003] But the existing soy sauce filling machine still has deficiencies, such as: 1. In the process of filling soy sauce, the soy sauce directly impacts the bottom of the bottle or the soy sauce in the bottle due to its own weight, and the soy sauce in the bottle often produces more The bubbles caused by the filling accuracy are inaccurate, and even the soy sauce overflows from the bottle due to foaming. For this reason, in the prior art, an umbrella-shaped flange is provided on the outer edge of the part where the return air pipe extends into the bottle, so as to prevent the filling along the return pipe. The soy sauce flowing down the trachea is guided so that the soy sauce flows to the inner wall of the bottle, so as to flow down along the inner wall of the bottle, so as to reduce the direct impact of soy sauce on the bottom of the bottle or the soy sauce in the bottle, and reduce the generation of foam. The center line is roughly on the same straight line. Therefore, in order to make the air return pipe smoothly extend into the bottle through the bottle guide block, the horizontal distance between the outermost end of the umbrella-shaped flange and the outer edge of the air return pipe is relatively small, so that the effect of guiding the soy sauce to the inner wall of the bottle remains the same. Not ideal, more foam will still be generated during the filling process

2. During the working process, it is unavoidable that the empty bottle cannot reach the bottle-supporting cylinder smoothly. At this time, the bottle-supporting cylinder goes up without load, but the filling machine cannot tell whether the bottle is in place, and still performs the vacuuming action on the bottle. This will cause the internal pressure value of the material tank to deviate from the predetermined range, which will affect the subsequent filling quality; of course, the Chinese patent No. "ZL 00239420.0" discloses a pure draft beer mechanical filling valve, which is provided with " No bottle, no vacuum part", but the structure of the "no bottle, no vacuum part" is relatively complicated, which is not suitable for the filling production requirements of soy sauce
