Automatic equal-liquid-level filling machine

Abstract

The invention discloses an automatic equal-liquid-level filling machine, which comprise an engine seat, an operating platform, a transmission structure, a driving structure, a receiving trough, a lifting structure, a material cylinder, a control device, a photoelectric sensor and a filling system, wherein the filling system consists of at least one filling subsystem; the filling subsystem comprises a filling pipe, a filling valve, a feeding pipe, a vacuum pipe, a vacuum sensor and a vacuum generator; the filling pipe is connected with the feeding pipe through the filling valve; the feeding pipe is communicated with the material cylinder; one end of the vacuum pipe is arranged nearby the filling pipe, and the other end of the vacuum pipe is connected with the vacuum generator; the vacuum generator is used for vacuumizing the machine to generate negative pressure; and the vacuum sensor is arranged at one end of the vacuum pipe close to the vacuum generator and is used for monitoring the variation of the negative pressure. The automatic equal-liquid-level filling machine has a simple structure, is high in filling speed and low in liquid loss and is suitable for high-viscosity materials and plastic bottles with thin walls.

Description

technical field [0001] The invention relates to a filling machine, in particular to an automatic equal liquid level filling machine. Background technique [0002] Liquid filling equipment is widely used in all walks of life. Theoretically speaking, liquid filling machines can be divided into normal pressure filling machines, pressure filling machines and negative pressure filling machines according to the filling principle. These models According to the type of filling volume, it can be divided into equal liquid level filling and equal volume filling. Among them, medium liquid level filling is the most widely used. The general equal liquid level filling machine adopts one of the above three filling principles. At the same time, vacuum suction is used to draw excess liquid out of the container. The continuous suction is generated by a vacuum pump connected to the vacuum tank and the switching valve. The filling valve consists of a filling sleeve in which a vacuum tube is use...

AI Technical Summary

Problems solved by technology

As mentioned above, these traditional equal-level structure filling machines use the vacuum pump to vacuum the liquid material to achieve equal-level filling during the filling process, which has complex structures, narrow application range, large errors, and wearing parts. Many, long maintenance time, slow filling speed, large loss of liquid material, high energy consumption, not suitable for high viscosity materials and most thin-walled plastic bottles, etc.
