Problems solved by technology

Although this method can complete the dispensing process, it has the following disadvantages: the gas is a compressible gas, which will cause certain fluctuations in the air pressure in the glue spray valve during the downward movement of the striker, so that the speed of the striker also fluctuates to a certain extent , resulting in differences in the glue output volume each time, which affects the consistency of the glue drop volume and reduces the glue spray quality; the pressure relief process of the high-pressure gas in the glue spray valve will produce great resistance to the movement of the firing pin, which reduces the speed of the firing pin. Thereby reducing the spraying capacity of the glue spray valve

Abstract

The invention discloses a novel striker dispensing valve. The novel striker dispensing valve comprises a valve body, an adhesive feeder and an adhesive discharger; a stop block is fixedly arranged atthe junction of the valve body and the adhesive feeder; an adhesive feeding chamber is arranged in the adhesive feeder and communicates with an adhesive inlet and an adhesive outlet of the adhesive feeder; a striker bar is arranged in the valve body; the top end of the striker bar is fixedly connected with a piston; an air inlet is formed in the position, on the upper portion of the piston, of thevalve body; the bottom end of the striker bar penetrates through a through hole in the middle of the stop block and is inserted into the adhesive feeding chamber; and the portion, between the stop bloc, and the piston, of the striker bar is sleeved with a spring. High-pressure gas is injected via the air inlet, the piston is pressed to dispense adhesives, the spring jacks up the piston to injectthe adhesives, the pressure intensity of high-pressure gas injected via the air inlet is controlled to be coincident, accordingly the consistency of the adhesive discharging volume each time is ensured, and the dispensing quality is improved.

Description

technical field [0001] The invention relates to the technical field of fluid dispensing equipment, and specifically designs a novel striker dispensing valve. Background technique [0002] Dispensing machine, also known as glue applicator, glue dispenser, glue machine, etc., is an automatic machine that controls fluid, drips and coats the fluid on the surface of the product or inside the product. The glue dispenser is mainly used for accurate pointing, injecting, coating, and dripping of glue, paint and other liquids in the product process to the precise position of each product, and can be used to achieve dots, lines, circles or arcs. [0003] The dispensing valve is an important part of the dispensing machine. The jet dispensing valve currently used in the industry is mainly an air-spring type dispensing valve. Moving upward and compressing the spring, the colloid enters the nozzle. At this time, the high-pressure gas is cut off, and the striker moves downward under the fo...
