Plug needle dispensing valve is a kind of rubber control valve which extrudes glue by pneumatic driving ejector rod. The 2121 dispensing valve manufactured by the middle system belongs to a kind of rubber control valve with good performance in a wide range of applied industries. It is installed in 221 dispensing machine or 331 dispensing machine and other automation equipment to play a high advantage of automatic glue control accuracy. The common problems such as glue-free valve are greatly reduced by precision manufacturing. It can be used in the dispensing of parts silicone ring paint or packaging dispensing of small products.

Effectiveness of Application in Automation Equipment

 

331 dispensing machine is a desktop automation equipment, which can be used for batch production of silica gel ring dispensing paint and product packaging dispensing. The reason called 331 dispensing machine is that its dispensing stroke is 300*300*100, the work station can complete the production of semi-finished products in batches, 2121 dispensing valve has the advantages of corrosion resistance, simple operation, labor and time saving, and so on. The corrosion resistance of stainless steel is good. The utility model has high service life and can improve the solution of the problems such as no glue in the plugging glue valve. Installed on 331 dispensing machine, dispensing is evenly packed at the outlet through the set path and parameters. When dispensing silicone rubber ring, 2121 dispensing valve is used to control low flow uniformity error, fine glue quantity is controlled and excessive glue quantity is avoided, which will affect the appearance effect.
