Dripping-proof low-bubble linkage-type filling structure

Abstract

The invention discloses a dripping-proof low-bubble linkage type filling structure. The dripping-proof low-bubble linkage type filling structure comprises an air cylinder (1), a feeding device (2) and a filling head (3), wherein the filling head (3) comprises a material cavity (301); the material cavity (301) is internally provided with a material pushing rod (302); the top end of the material pushing rod (302) stretches out of the material cavity (301); the material pushing rod (302) is connected with a piston rod (101) of the air cylinder (1); a spiral discharging pipe (4) is arranged at the bottom end of the filling head (3); the feeding device (2) comprises a material storage bucket (201), a material pipe (202) and a material returning absorption cabin (203); the material storage bucket (201) is communicated with the material returning absorption cabin (203) through the material pipe (202); the material returning absorption cabin (203) is communicated with the material cavity (301); a solenoid valve (5) is arranged between the material storage bucket (201) and the material returning absorption cabin (203). The dripping-proof low-bubble linkage-type filling structure can sufficiently avoid dripping; dropped materials can be recycled to the material returning absorption cabin and the spiral discharging pipe is arranged at the bottom end of the filling head, so that a liquid impact force can be buffered sufficiently and bubbles are prevented from being generated in a filling process.

Description

technical field [0001] The invention relates to the field of liquid filling and packaging, in particular to an anti-drip and low-foaming interlocking filling structure. Background technique [0002] In the liquid packaging equipment of the prior art, in order to solve the dripping phenomenon in the filling process and the inconvenience of daily flushing and maintenance of the filling head, vacuum suction or air blowing are usually used to prevent dripping solutions. For example, CN203033745 discloses An anti-drip filling head, at the end of a filling, blows air into the air channel through the air access point, and blows off the material remaining at the lower end of the valve body to prevent dripping, but once it is completed At the end of the filling, after the gas is blown, the filling liquid will increase the gas, which will easily generate bubbles and affect the filling of the liquid. Especially in the filling process of some food liquids, there are strict restrictions ...

Problems solved by technology

[0002] In the liquid packaging equipment of the prior art, in order to solve the dripping phenomenon in the filling process and the inconvenience of daily flushing and maintenance of the filling head, vacuum suction or air blowing are usually used to prevent dripping solutions. For example, CN203033745 discloses An anti-drip filling head, at the end of a filling, blows air into the air channel through the air access point, and blows off the material remaining at the lower end of the valve body to prevent dripping, but once it is completed At the end of the filling, after the gas is blown, the filling liquid will increase the gas, which will easily generate bubbles and affect the filling of the liquid. Especially in the filling process of some food liquids, there are strict restrictions on the gas content. The technical solution cannot be used; CN203295155U discloses a vacuum back-suction anti-drip filling head, the center cavity of the inner plug of the filling head is provided with an inner plug back-suction hole connected with the cylinder piston rod back-suction hole, which solves the problem of The dripping of the liquid improves the filling accuracy, but in the cavity between the suction hole and the filling head, the suction material cannot be used next time, and the suction material in the suction hole needs to be cleaned regularly, which is inconvenient to use

[0003] At the same time, when the liquid filling material enters the bottle or box through the filling head, air bubbles are likely to be generated under the impact of the liquid, which affects the accuracy of measurement, and it is easy to cause liquid overflow, which affects the packaging quality of the liquid.
