Filling device of filling machine

Abstract

The invention discloses a filling device for a filling machine, having a structure that the filling device comprises a quantity cylinder body, connecting pipes, a switch valve and a valve core. The structure has the main points that an inner piston is arranged inside the quantity determining cylinder body; a first power mechanism is arranged above the inner piston; a first connecting pipe is arranged below the quantity determining cylinder body; the quantity determining cylinder body is communicated with the inside of the first connecting pipe; the other end of the connecting pipe is connected with the switch valve, and is communicated with a hole arranged on one side of the switch valve; the valve core is arranged inside the switch valve; the upper end of the valve core is provided with a second power mechanism; the other side of the switch valve is connected with a second connecting pipe; the other end of the second connecting pipe is connected with a material cylinder of the filling machine; and a filling valve adopts the rising height of the inner piston to realize the quantity. As the size of the filling valve is fixed, the rising height of the filling valve is the same, the capacity is not changed, and the quantity is accurate.

Description

technical field [0001] The invention relates to a filling machine, in particular to a filling device of the filling machine Background technique [0002] At present, the filling device of the filling machine realizes the connection and closure of the feed port and the discharge port through a three-way cock or a flat rotary valve. The principle is to extend the discharge port into the bottle, and when the liquid rises to When the discharge port is blocked, the quantitative control of the discharge is realized. However, when the quantitative control of this structure is adopted, when there is an error in the size of the bottle, the actual volume in the bottle will change at this time, resulting in The quantification is inaccurate, and this type of filling device has media dripping at the discharge port after filling, especially with granular media, if it is meat, it will seriously affect the product quality and the sealing yield. In addition, This filling device also uses a ...

[0002] At present, the filling device of the filling machine realizes the connection and closure of the feed port and the discharge port through a three-way cock or a flat rotary valve. The principle is to extend the discharge port into the bottle, and when the liquid rises to When the discharge port is blocked, the quantitative control of the discharge is realized. However, with the quantitative control of this structure, when there is an error in the size of the bottle, the actual capacity in the bottle at this time will change, resulting in Quantification is inaccurate, and with this type of filling device, there is a medium dripping at the discharge port after the filling is completed, especially the granular medium, which seriously affects the product quality and the sealing yield. This filling device also uses a sealing ring, resulting in incomplete cleaning and easy wear
