Abstract

The invention relates to a multichannel synchronous filling device of a liquid filling machine, which comprises a liquid storage bath, a filling unit, a mount, a lifter plate, a servo motor, a ball screw and a screw-nut sleeve. the servo motor is fixed on a fixed plate of the mount, the screw-nut sleeve is fixed on the lifter plate and is in screwed fit with the ball screw; in the filling unit, a filling cylinder is in ceiling mounting, the body of a cylinder sleeve towards downward, a piston rod towards downward, a three-way connection is provided on the lower end face of the filling cylinder, a three-way valve is connected between the liquid storage bath and the three-way connection through a flexible pipe, the discharge hatch of the three-way valve is connected with a filling nozzle. The structure of the invention has no bubbling and draining phenomena, and is capable of saving the filled raw materials, and avoiding accident damage on operators caused by the leakage of the materials, the filling machine can reach maintenance-free requirement. The power consumption for driving lifting is low, so that the energy and the cost can be saved. The product type can be replaced in a convenient and fast mode, so that the user requirement can be satisfied.

Description

Technical field:

[0001] The invention relates to a vertical liquid filling machine, in particular to a vertical piston type constant volume liquid filling machine. Background technique:

[0002] Most of the existing vertical liquid filling machines use piston-type filling cylinders to achieve filling. Among them, the filling cylinders are usually driven by air pressure, that is, the cylinder drives the piston in the filling cylinder to twitch back and forth to realize the filling of liquid materials. Filling, but due to the existence of pneumatic filling filling machines ① single filling speed, when the filling volume is close to full, the filled liquid is prone to foam overflowing from the mouth of the bottle, to overcome this shortcoming can only be reduced filling speed, so that The filling efficiency is low, and the production capacity of the whole machine cannot be brought into play. ②The filling accuracy is not high. Since the pneumatic filling machine uses pressure g...
