An intelligent fine atomization valve

Abstract

The invention relates to the technical field of fluid glue pushing equipment, in particular to an intelligent fine atomizing valve. The feed depth of a motor output push rod of a motor is controlled by a computer control device, the gap width between a needle head of a valve needle and a glue pushing head can be controlled by different feed depths, gas enters a piston cavity through a first channel and pushes a piston to move upwards after entering an electromagnetic valve, the piston drives the valve needle to rise, the valve needle is stopped after touching the motor output push rod, glue liquor of a glue filling nozzle passes a valve needle channel and finally flows out through the gap between the needle head of the valve needle and the glue pushing head, an electrical proportional valve controls inlet gas pressure through the computer control device when the glue pushing head pushes glue, the gas enters an atomizing gap through a second gas inlet channel, glue liquor of the glue pushing head is sprayed out of an atomizing nozzle of an atomizing pipeline in a misty form by gas pressure of the atomizing gap, and the electrical proportional valve is controlled by the computer control device to accurately control the gas pressure, so that the atomizing valve can accurately control atomizing degree.

Description

technical field [0001] The invention relates to the technical field of fluid glue dispensing equipment, in particular to an intelligent fine atomization valve. Background technique [0002] An atomizing valve is a device that turns a liquid into fine droplets and discharges it in the form of a mist. The atomizing valve works by the pressure in the container. Usually the air pressure in the spray tank is much higher than the atmospheric pressure. The liquid in the container is squeezed out due to the air pressure. Sieve into fine beads and spray to form a spray. [0003] In the prior art atomizing valve, before the glue is atomized, it is necessary to manually adjust and fix the rising stroke of the valve needle, and set a fixed glue flow rate. In different glue flow situations, different adjustments need to be made manually, which cannot Realizing automatic operation will affect the glue output efficiency; the spray air pressure needs to be adjusted manually, and the degre...
