METHOD AND A DEVICE OF REPROCESSING OF CYLINDRICAL FORM PLASTIC PRODUCTS Russian patent published in 2005 - IPC

FIELD: household wastes reprocessing.

SUBSTANCE: the invention presents a method and a device of reprocessing of household wastes, mainly - plastic bottles. The method of reprocessing of cylindrical form plastic products, predominantly, plastic bottles, provides, that first they cut off a non-cylindrical part of the product, then the cylindrical part of the product is cut along a screw line as a band. The band or a pack of the bands is twisted, subjected to a heating up to a thermal reflow, drawn and pressed out between the rollers. The device for reprocessing of the cylindrical form plastic waste products, predominantly plastic bottles contains a feeding mechanism and a unit of cutting of the products -installed on the frame and it is equipped with a tool for working of the cut in the form of the band-type parts of the reprocessed products, which contains a shuttle mechanism with an electrical drive, a fan and a device for the band drawing and compaction containing an electrical drive, the rollers with an incision and the rollers pressing tool. The feeding mechanism is made in the form of a screw gear, the screw of which is connected to a device gripping the plastic cylindrical form products, and an electrical drive installed on the guides, and a guide support. The products cutting unit contains the thermal device made in the form of nichrome wire mounted on a spring-loaded lever, and a mechanical cutting device - containing a dead knife and a rotor knife with the electromotor - all installed on a deck, which is balance fixed on the frame. The invention ensures production of an end-product, in particular, a band twisted and thermally reflown into a bar or a harness made out of the twisted and thermally reflown packs of bands, to reduce power input of the production process.

EFFECT: the invention ensures production of the end-products in the form of bars or harnesses made out of the twisted and thermally reflown packs of bands and reduction of power input for the production process.
