Description

Technical Field

[0001] The utility model relates to the technical field of striker valves, in particular to a striker valve. Background Art

[0002] In recent years, with the rapid development of the automation industry, the glue dispensing machine industry has been increasingly used in the automation industry. The needle valve has become an inseparable standard accessory in the glue dispensing machine industry. During use, the needle valve effectively, quickly, accurately and stably controls the amount of glue fed in. This effectively ensures the fluidity and stability of the glue. It solves the problem of the glue dispensing machine dispensing more or less glue during the dispensing process, ensuring the uniformity and beauty of the glue and the product dispensing part.

[0003] The patent document with the prior art publication number CN112756204A provides a needle valve, which includes a valve body, a needle seat and at least two sets of connecting devices, the connecting device including an upper connecting piece, a lower connecting piece and a fastener, one of the side surfaces of the upper connecting piece protrudes outward to form a protrusion, the top surface and one of the side surfaces of the lower connecting piece are simultaneously recessed inward to form a groove for accommodating the protrusion, the fastener is screwed into the threaded holes of the lower connecting piece and the upper connecting piece in sequence, so that the lower connecting piece and the upper connecting piece are fastened together by the cooperation between the protrusion and the groove, wherein the upper connecting piece is fixed on the valve body, and the lower connecting piece is fixed on the needle seat, so that the needle seat is fixed under the valve body by the cooperation between the upper connecting piece and the lower connecting piece, or the lower connecting piece is fixed on the valve body, and the upper connecting piece is fixed on the needle seat, so that the needle seat is fixed under the valve body by the cooperation between the lower connecting piece and the upper connecting piece.

[0004] However, the existing striker valve uses a cylinder to feed glue. The cylinder piston reciprocates to push the glue to flow in the pipeline. The amount of glue fed is controlled by the air pressure, but there is an unstable factor in the air pressure. The air pressure will be high or low, which will affect the stability of the glue flow and cannot effectively and accurately control the amount of glue. For this reason, we propose a striker valve.

[0015] The utility model provides a striker valve, which has the following beneficial effects:

[0016] (1) This type of striker valve is provided with a servo motor, a screw rod, a slider and a valve stem. When the striker valve is used, when the glue enters the valve body through the glue inlet, the servo motor drives the screw rod to rotate through the coupling, and the slider moves up and down due to the rotation direction of the screw rod. At this time, the slider drives the valve stem to move together, and the striker block squeezes the glue, and the glue flows into the dispensing head and enters the dispensing needle through the discharge pipe for dispensing. In this way, the striker valve uses the motor analog quantity to control the movement of the valve body, control the glue feeding amount of the dispensing machine, and accurately and effectively control the glue sprayed on the product by the needle head to be uniform and beautiful.
