    Working principle of screw valve

    Date: 2019-11-08

    主要部件是螺杆和定子二部分组成。 The main components of the screw valve are a screw and a stator. Moreover, the stator and the screw can form a sealed cavity. The glue is pushed forward by the screw in the sealed cavity, and the larger the rotation angle is

    The more glue produced. Because its feed inlet is on the rear side and rotates eccentrically, its structure is relatively large. If the screw does not turn, even the inlet

    Under pressure, it will not produce glue.

    The screw valve controls the time, air pressure, and screw speed, and performs dot dispensing and scribing with high precision. It is suitable for medium to high viscosity.

    Fluid precision screw valve. Screw valve uses a screw to dispense through forward displacement instead of movement, which can achieve ultra-precise control of the dispensing process

    . The modular design of the valve allows quick and easy loading and unloading of the screw connector cavity without removing the valve body from the device. Valved

    Another feature is that the screw connector cavity of the valve can be replaced by a suitable screw drive device .

    精密螺杆阀外形轻巧,方便手握;操作简单,灵活性强,点胶精度高。 Screw valve features: Precision screw valve is lightweight and easy to hold; simple operation, strong flexibility and high dispensing accuracy. Application of screw valve

    Domain: Suitable for solder paste, silver paste, red glue, grease, UV glue, silicone, etc., used for solder paste welding, chip bonding, chip packaging,

    Processes such as dams use Z-direction rotating screws for material transportation, which solves the pressure-dispensing method. The pulsation caused by the shrinkage of the gas

    , The problem of inconsistent glue output. The motor is controlled separately for forward and reverse rotation. The forward rotation can use the material to be uniformly squeezed out according to the required flow.

    Rotating to the side can realize the suction of hot melt adhesive, avoid the phenomenon of glue leakage, wire drawing and so on .

    1.代替人工特定的点胶作业,实现机械自动化的生产;2.易学易懂,不需外接教导器 Advantages of screw valve: 1. Instead of manual specific dispensing operations, realizing mechanical automation production; 2. Easy to learn and understand, no external teaching device

    , It is more convenient to debug than similar products, simple and convenient, high-speed and accurate; 3. With drawing points, lines, areas, arcs, irregular curve dispensing, etc.

    4. Precise and constant dispensing size .
