SPONGES are designed to accommodate the flexibility of robotic stacking operations and vacuum lifting systems. The most important feature of the sponge suction device is that it is designed like a honeycomb-shaped hole, each hole is controlled independently. When the product is sucked, the vacuum will be opened automatically. Once it touches the hole or uneven place, the suction hole will be closed automatically, this can maintain the entire vacuum system does not leak, and achieve the effect of successful handling. This product is suitable for hollowed-out workpieces or multi-workpieces one-time handling, widely used in carpentry, food, medicine, building materials, tobacco and other industries. For example, bricks, planks (wet or dry) , cans, drums, plastic wrap, breathable parts (cartons, bags) , flat or rough parts, hollow parts and so on can be moved. For products with uneven or even perforated surfaces, where there is no definite suction area on the surface, or even products of various sizes and so on, CVT vacuum sponges can absorb these products very well. By using CVT vacuum sponges, we do not need to replace the fixture, for these irregular products can easily solve the problem of absorption difficulties. Whether it is for the logistics industry, small traders or factories, CVT sponges are widely used to carry a whole tray of cans, or a number of carton stacking, furniture factory door frames, etc. , do not need to identify whether the product is porous, whether the product is correct, or the number of different products and so on, these products can be easily extracted and handled. The Suction Cup can be used to adsorb single or multiple strip-shaped or block-shaped arbitrary workpiece without adjusting the position of the Suction Cup.
