The most important feature of the sponge suction device is that it is designed to be similar to a honeycomb-shaped Hole, each hole is controlled independently. When the product is sucked, the vacuum will be opened automatically, and 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 hollowing out work piece or multi-work piece one-time handling, widely used 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. The CVT vacuum sponge can absorb the products with uneven surface, even the products with holes, the surface has no definite suction place, even the products with various sizes, etc. 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, you can easily carry out these products to absorb. The Suction Cup can be used to adsorb a single or a plurality of strip-shaped or block-shaped arbitrary workpieces at will, and the position of the Suction Cup need not be adjusted.
