Filling action mechanism of filling machine

Abstract

The invention discloses a filling action mechanism of a filling machine. The filling action mechanism is characterized by comprising a mechanical arm main shaft, wherein one end of the mechanical arm main shaft penetrates through a hollow speed reducer and is connected with one end of a large mechanical hand arm; the other end of the large mechanical hand arm is connected with one end of a small mechanical hand arm through a mechanical hand countershaft; the output end of the hollow speed reducer is connected with the small mechanical hand arm through a connecting joint, a first movable joint and a second connecting rod; the other end of the small mechanical hand arm is provided with a needle rack fixing shaft; the needle rack fixing shaft is provided with a needle rack; and the needle rack is always horizontal to the ground surface through the effect of movable devices and is provided with a filling needle. The filling action mechanism has the characteristics of being high in integration level, being capable of realizing modularized installation and disassembling, being more convenient to maintain, and the like.

Description

Technical field [0001] The invention relates to a filling action mechanism of a filling machine, which is used to complete the filling of liquid medicine and can also be used in the field of food and cosmetic packaging equipment. Background technique [0002] In recent years, with the rapid development of freeze-dried preparations at home and abroad, many pharmaceutical manufacturers have strict requirements on the cleanliness of the environment during filling and the continuous increase in the speed of the filling machine, which requires the filling machine to operate more Safe and stable. In the existing continuous filling technology, there are two main ways to complete the filling action: one is to realize the up and down and following movement of the needle during filling by a cam, and the other is to drive the slide by two servo motors respectively. The block slides along the straight line of the shaft, thereby driving the up and down and left and right movements of the fil...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: rely on the cam to realize the mechanism of the up and down and follow-up movement of the filling needle, the control accuracy and stability of the filling needle position depend on the machining accuracy of the cam and the quality of the cam curve, and for different sizes The bottle needs to be replaced with a cam, which cannot be used universally; through two servo motors, the slider is driven to slide linearly along the axis, thereby driving the liquid filling needle up and down and following the movement mechanism, which has very high requirements for installation, and the axis and the linear sliding bearing are long. The friction of time will cause wear and affect the accuracy
