Abstract

The invention relates to a piston type metering valve. The piston type metering valve comprises a glue inlet and outlet control device. The glue inlet and outlet control device comprises a base body.Water-drop-shaped grooves are formed in the upper surface of the base body, and each water-drop-shaped groove comprises a feeding inlet and a discharging outlet, is only used by one kind of glue, andis used for avoiding mixing of the glue. The glue inlet and outlet control device comprises an adapter plate. External glue supply pipelines are arranged on the adapter plate, and the feeding inlets directly communicate with the external glue supply pipelines and are used for enabling the external glue to directly flow into the water-drop-shaped grooves. Only one water-drop-shaped groove is formedin the upper end face of the base body, and only one water-drop-shaped groove is formed in the lower end face of the base body. A piston rod is arranged on the glue inlet and outlet control device, and a gluing control device is arranged on the top of the piston rod. The piston type metering valve can strictly control the glue quantity, can rapidly, accurately and repeatedly conduct glue injection, avoids mixing of the glue, and is high in practicability.

Description

technical field [0001] The invention relates to a glue injection device, in particular to a piston type metering valve device for precise glue injection. Background technique [0002] At present, among the glue injection methods in many glue injection equipment, according to the glue quantity control principle, it can be mainly divided into the pressure time function method and the screw control method to realize the glue quantity control. [0003] The pressure time function method is mainly affected by the air pressure, the glue discharge time, the equipment running speed, the size of the needle nozzle and so on. By controlling the time and air pressure and the relationship between them, the glue pressure is matched with the function of time to achieve the predetermined glue volume and the diameter of the glue point. Usually, the glue volume is proportional to the pressure and time. However, the pressure-time method is subject to many constraints, which affect the accuracy...
