Problems solved by technology

However, due to the limited manufacturing capacity of the spring, it is difficult to control the amount of back suction. In high-precision flow control, the flow consistency is poor
[0003] There is also a dotting valve in the field of gluing. The dotting valve specifically includes two types: one is to use the air pressure and the spring to collide with each other to produce liquid, but the reliability is poor, and the accuracy will be lost as the spring ages; the other is The first is to use piezoelectric ceramics to generate high-frequency vibrations, so that glue and liquid are ejected, with high precision and good consistency, but the cost is high and the life of piezoelectric ceramics is poor.

Abstract

The invention discloses an on-off valve. The on-off valve comprises a valve body with a valve cavity, a collision pin and a magnet opposite to the collision pin, wherein at least part of the collisionpin is arranged in the valve cavity, and the collision pin comprises a shell and an electromagnetic coil located in the shell. The collision pin comprises the electromagnetic coil, due to the currentdirection changes in the electromagnetic coil, the magnet and the collision pin are mutually attracted or repelled, the collision pin moves in the axial direction of the electromagnetic coil, and accordingly a fluid channel is opened or closed. According to the on-off valve, the fluid flow control precision can be improved.

Description

technical field [0001] The present application relates to the technical field of gluing equipment, in particular, to an on-off valve and a gluing device. Background technique [0002] The existing liquid on-off valve mainly adopts the on-off mode of start-up control, and also has the on-off mode of electric control. It is difficult to control liquid or glue, especially the glue application process, which will cause serious bulking. The big head phenomenon can be reduced by adopting the back-suction valve. The back-suction valve uses a spring to push out the internal thimble, which produces a reverse thrust on the liquid, so that the liquid remaining in the pipe wall is sucked back. However, due to the limited manufacturing capacity of the spring, it is difficult to control the amount of suction back, and the flow consistency is poor during high-precision flow control. [0003] There is also a dotting valve in the field of gluing. The dotting valve specifically includes two...
