Aluminum-plastic fragment grinding and separating device and method

Abstract

The invention belongs to the technical field of separation, and particularly relates to an aluminum-plastic fragment grinding and separating device. The aluminum-plastic fragment grinding and separating device comprises a conveying device and a supporting frame used for supporting and fixing the conveying device; a fixing plate is arranged above the conveying device at an interval; a pressing roller, a scraper, a groove and a cam are arranged between the fixing plate and the conveying device; the roller face of the pressing roller and the outer side edge of the scraper are arranged in an adjacent and spaced mode; a supporting plate is arranged below the pressing roller; a baffle is arranged on one side of the pressing roller at an interval; the top wall of the baffle is fixedly connected with the groove; the cam is arranged in the groove part of the groove, and the cam is connected with the pressing roller through a transmission chain; and the baffle is elastically connected with the fixed plate. The device is simple in structure and easy to operate; under the matching action of the pressing roller arranged above a conveying belt and the supporting plate arranged below the pressing roller, aluminum-plastic fragments in a circular curved surface shape are pressed into a flat and smooth shape; and the aluminum-plastic fragments which are tightly attached to one another can be better separated conveniently in the follow-up process.

Description

technical field [0001] The invention belongs to the technical field of separation, and in particular relates to a rolling separation device for aluminum-plastic fragments. Background technique [0002] At present, there are many optical fibers and communication cables on the market. The sheath of the outer layer of the optical fiber or communication cable is made of a layer of plastic and aluminum (or iron) adhesion as a whole. After use of such materials, people pay attention to their recycling insufficient. In the early days, the use of incineration to dispose of waste materials would cause a large amount of toxic gases to be produced from waste outdoor interplanted plastics, which would endanger human health; landfill treatment would occupy land and cause long-term pollution of soil and groundwater. [0003] At present, in the process of separating the waste aluminum-plastic cables formed by compounding aluminum foil and plastic, the waste cables are usually crushed by a...

Problems solved by technology

In the early stage, the use of incineration to dispose of waste materials will cause a large amount of toxic gases to be produced from the waste outdoor interplanted plastics, which will endanger human health; landfill treatment will cause land occupation and long-term pollution of soil, groundwater and other hazards

[0003] At present, in the process of separating the waste aluminum-plastic cables formed by compounding aluminum foil and plastic, the waste cables are usually crushed by a shredder and then directly separated, and the crushed aluminum-plastic fragments are not separated during this separation process. Rolling process, in this case, the aluminum-plastic materials cannot be fully separated; very few pieces are rolled before the aluminum-plastic pieces are separated, but the existing rolling devices cannot Rolling the aluminum-plastic fragments uniformly enough makes the rolling effect of the aluminum-plastic fragments not good, which in turn affects the separation effect of the aluminum-plastic materials
