The ultra-thin cement bag compounding and bagging combined unit developed by Zhejiang and Pingyang Kaida Packaging Machinery Factory is a new generation of high-efficiency, low-consumption, cement bag production equipment. It has been developed and solved the cement bag thinning without equipment. Cement bag production needs to rely on the two major problems of the sea.
The national standard GB9774-2002 "Cement bags" stipulates that the quality index per unit area must not be less than the fixed value, which requires the cement bag manufacturer to produce the film-plastic woven bags, and in the premise of achieving unit area quality, the minimum must be used. The raw materials to produce the highest tensile load of cement packaging bags, relative to increase the basic thickness of the film bag, reduce the thickness of the coating film to increase the tensile load, that is to say, on the premise of ensuring a certain quality index, can reduce the cement bag The cost of production, which is very welcome for the cement plant or the cement bag manufacturing plant, therefore, this development trend is that the film is coated with thinner.
The combined part of the combined unit uses a specially designed screw and barrel to fully plasticize the raw material and extrude it through a high-precision coat hanger die. After being cast and stretched, it becomes an ultrathin film and circle with a certain temperature. The tubular plastic woven bag is directly pressure-composited, and the thickness of this composite coating can reach 5g/m2 or less.
The combined unit combines the five processes of compounding, automatic cutting of scraps, automatic boring, automatic printing, offset folding, and seven-word cutting. It not only reduces the use of materials, reduces the cost of the bag, but also enables product quality. Improve and make the finished product bag standardized, uniform and beautiful.
The combined unit not only has many advantages, but also is economical and affordable. It is an ideal equipment for cement bag manufacturers.
