The utility model relates to a high-speed diaphragm belt backdraft functional dispensing valve, which comprises a cylinder block, a rubber chamber block and a rubber nozzle connected sequentially from top to bottom. A step is arranged in the rubber chamber block, and a diaphragm is installed at the top of the step. The cylinder block and the rubber chamber block are penetrated with an upper connecting shaft, the rubber chamber block and the rubber nozzle are penetrated with all the lower connecting axes, and the upper connecting axle passes through the diaphragm and the rubber chamber block. The diaphragm type power transmission is used to completely separate the high-pressure rubber chamber from the power cylinder diaphragm, and the diaphragm itself is deformed when the rubber valve is opened and closed up and down by the special shape and toughness of the diaphragm, which ensures the transmission of the axial power and makes the rubber firmly separated in the rubber chamber, effectively avoiding the situation of reverse rubber spill. Reverse conical coupling is adopted to close the rubber valve while sealing the rubber chamber and generating negative pressure in the rubber chamber at the moment of closing the rubber valve. Some rubber is sucked back into the rubber chamber so as to cut off the rubber circuit quickly and avoid pulling the rubber.

一种高速隔膜带回吸功能点胶阀
本技术涉及电子领域,具体涉及一种高速隔膜带回吸功能点胶阀。
技术介绍
点胶阀在各大消费电子,汽车,家电等众多制造厂得到广泛应用。目前市场上现有点胶阀其是在点胶时容易拉胶(不带回吸),长时间使用时,由于动力气缸轴直连撞针并用普通的轴和密封圈密封,高压打胶时容易向上溢胶至动力气缸体内部,致使胶阀损坏。本专利技术主要解决以上两点问题,即:1,采用隔膜式动力传输,将高压胶室与动力气缸用隔膜完全隔开,利用隔膜的特殊形状与韧性,在胶阀上下开合时隔膜自身发生形变,即保证了轴向动力的传输又使胶牢牢地隔在胶室内,有效的避免了胶反向溢出的情况;2,胶嘴设计采用反向锥面耦合的精密配合,即保证在关闭胶阀的同时密闭胶室又在关闭胶阀的瞬间胶室内产生负压,将一部分胶回吸到胶室内密封起来,从而迅速切断胶路,避免了拉胶的情况。
