Filling system adopting time pressure method

Abstract

The invention relates to a filling system adopting a time pressure method. The filling system comprises a filling structure, a constant-pressure device, a control valve, a distribution pipe and soft pipes. The filling system is characterized in that the constant-pressure device is connected with the distribution pipe which is provided with the control valve and is connected with different diaphragm valves with metal diaphragms on the filling structure by the different soft pipes. The filling system has the advantages that the filling system adopting the time pressure method is applied to a filling linkage line, the off-line cleaning / SIP compatibility can be realized simultaneously, any equipment does not need to be replaced for 0.1ml-20ml dosage, complete isolation of a filling area and a driving part can be realized, and simultaneously, the filling accuracy is met by increasing and controlling the micro-pressure control accuracy in a buffering tank.

Description

technical field [0001] The invention relates to a time-pressure method filling system used in a filling linkage line, belonging to the technical field of packaging equipment for food, medicine and cosmetics. Background technique [0002] In the existing filling structure, three filling methods are generally adopted: plunger filling, peristaltic pump filling, and time pressure filling. For example, the application number is CN200720110152, and the Chinese patent titled "Plunger Type Quantitative Filling Device" discloses a device that adopts plunger type filling, including a stepping motor fixed in the frame and driven by the stepping motor. The mechanism drives the rotating turntable. The turntable is equipped with an adjustable bottom block. The bottom block is connected to the plunger. The rotation of the turntable drives the plunger to make a reciprocating linear motion. Pipe and discharge pipe, the discharge pipe is connected to the injection nozzle, the filling materia...

AI Technical Summary

Problems solved by technology

[0005] The above three filling methods all have disadvantages: plunger filling cannot realize in-situ sterilization (SIP for short in English); the cost of peristaltic pump is high, and it is difficult to use for multi-head filling; time pressure method Filling is characterized by fast filling speed and simple device structure. However, due to the difficulty of micro-pressure control, and the fluctuation of filling pressure has a great impact on the stability of filling volume, the filling accuracy of small doses is low. At present, the time Pressure filling is mainly used for large-dose filling
