Description
Technical Field
The invention relates to a method for packaging bulky shredded paper bags, in particular to a full-automatic six-side film wrapping method for bulky blocky shredded paper bags.
Background
Paper is widely used as a main medium for recording information. Since the paper sheets have some important information recorded thereon, the discarded paper sheets cannot be discarded at will for confidential units, and must be destroyed. In order to deal with large-batch paper processing, a destruction center is built to intensively process the paper media recorded with confidential information.
At present, the destruction mode of paper media in the market is mainly pulverization, the paper media are pulverized, then the pulverized paper is pulverized and compressed into blocks, and finally, the compressed paper packets are transported to a pulping factory for pulping treatment.
Generally, the compressed shredded paper has a large volume, a length of 750mm to 1100mm, a width of 550mm to 700mm, a height of 450mm to 850mm, and a weight of about 100 kg to 400 kg. Because the crushed paper bag body after compression is large in volume and heavy in weight, the crushed paper bag body is often directly transported away without being wrapped, so that the phenomenon of scattering often occurs in the transportation process, and great adverse effects are generated on confidential work. Therefore, the staff can carry out bagging treatment on the pressed shredded paper bag, but the compressed shredded paper bag is large in volume and heavy in weight, cannot be carried, is extremely low in bagging efficiency, and greatly consumes manpower and material resources.
At present, automatic thermal shrinkage packaging equipment is available on the market, and is used for placing a packaged object in the middle of a packaging film, enabling the packaging film to wrap the packaged object by overturning the packaged object, then cutting the packaging film for sealing, and finally enabling the packaging film to be thermally shrunk and attached to the surface of the packaged object through hot air and cold air switching. The packaging mode is suitable for small and light articles; the full wrapping of the four sides of the large-volume articles can be realized, and the left side surface and the right side surface can not be wrapped.
The large and blocky objects are generally packaged in a four-side winding and wrapping mode, namely, the objects to be packaged are rotated through a rotating platform, and then the packaging film is pulled to carry out multilayer winding on the objects so as to achieve the purpose of four-side packaging. The disadvantages of this packaging approach: only four surfaces of the large block-shaped object can be packaged, and the rest two surfaces cannot be wrapped, so that certain limitation exists.
