點膠閥是在點膠機設備上用來完成點膠動作的一個重要單元，那麼點膠閥有哪些種類及特點呢？接下來點膠機廠家就來為你仔細介紹一下。點膠機上常見點膠閥有氣動和電動兩種，下面我們來對這兩種點膠閥進行詳細的介紹。
The dispensing valve is an important unit used to complete the dispensing action on the dispensing machine equipment, so what are the types and characteristics of the dispensing valve? Next point glue machine manufacturers will come to you for a careful introduction. The common point glue valve on the dispensing machine has two kinds of pneumatic and electric, the following we will be the two kinds of dispensing valve detailed introduction.
氣動點膠閥由氣缸、閥體和料缸三部分上下連接而成，氣缸和閥體用先進密封材料隔開，避免膠水侵入氣缸。料缸和氣缸連接在點膠閥閥主體上，與氣缸保證同心度。用電磁閥氣動氣缸運動，從而驅動中心杆上下運動，利用中心杆的上下運動達到對膠水的開啟和關斷作用。根據開啟和關斷的方式不同，從而分為：柱塞式點膠閥、頂針式點膠閥、提升式點膠閥、噴霧點膠閥、噴射點膠閥；開關方式不同，適用的流體也就不同，回吸式點膠閥採用向上運動關膠結構，使停膠同時瞬間回吸斷膠，減少餘留針頭上的殘膠，使點膠不產生滴漏、拉絲等現象。膠閥本體經鋁合金陽極化處理，密封材料採用最新四氟材料，接觸膠體部分均為耐腐蝕材料。
Pneumatic dispensing valve by the cylinder, valve body and cylinder three parts up and down connected, cylinder and valve body with advanced sealing materials separated, to avoid glue intrusion into the cylinder. The material cylinder and cylinder are connected to the main body of the dispensing valve valve, and the concentric degree is guaranteed with the cylinder. With the solenoid valve pneumatic cylinder movement, so as to drive the center rod up and down movement, the use of the center rod up and down movement to achieve the glue opening and shutdown effect. Depending on how it is turned on and off, thus divided into: plunger type dispensing valve, thimble type dispensing valve, lifting point rubber valve, spray point rubber valve, jet point rubber valve, switch mode is different, the applicable fluid is also different, the suction type dispensing valve using upward motion off the adhesive structure, so that the stop glue at the same time instantly back suction glue, reduce the residual glue on the remaining needles, So that dispensing does not produce drip, drawing and other phenomena. Rubber valve Body by aluminum alloy anodic treatment, sealing materials using the latest tetrafluoride materials, contact colloidal parts are corrosion-resistant materials.
電動點膠閥包括泵體和驅動部分，隨配定子，安裝簡單。採用定轉子結構設計，密封性能好。轉子和定子副形成自密封結構，易於替換。通過轉子在定子腔的定向旋轉作用，實現介質輸送功能，輸送過程不對介質性能產生任何的影響。 同時可以通過電機反轉，輕鬆實現介質回吸功能，確保介質和材料的清潔，無滴漏,無汙染。
Electric dispensing valve includes pump body and drive part, with stator, easy to install. The use of fixed rotor structure design, sealing performance is good. Rotor and stator pairs form self-sealing structures that are easy to replace. Through the directional rotation of the rotor in the stator cavity, the dielectric conveying function is realized, and the conveying process does not have any influence on the performance of the medium. At the same time can be reversed through the motor, easy to achieve the media suction function, to ensure that the media and materials clean, no drip, no pollution.
