Device and method for separation of thin bottle sheet and label paper

Abstract

The invention relates to a device for chemical fiber separation of label paper, and especially relates to a device and a method for separation of a thin bottle sheet and label paper. The device for separation of the thin bottle sheet and the label paper is a separation tank, an auger semicircular cylinder is arranged at the bottom of the separation tank, two mutually-engaged horizontal pushing auger are arranged in the auger semicircular cylinder, the upper part of separation tank is respectively and successively provided with a plurality groups of beating rod material dispersing mechanism, a first slow draw paddling rod pushing mechanism, a material pressing rotary mechanism, a second slow paddling rod pushing mechanism, a plurality groups of scraper push mechanism and a network type discharging slanting conveying belt device, a slanting discharging water filtering mechanism is arranged at an outlet of the separation tank, the separation tank is provided with a notch at the rear end of the material pressing rotary mechanism, and a discharging slanting auger is arranged below the notch. The device greatly reduces the amount of labor of workers, so that the separation speed is quickened, the separation efficiency and the discharge stability are greatly improved, and the device has the advantages of simple structure and convenient use.

Description

technical field [0001] The invention relates to a device for separating label paper from chemical fibers, in particular to a device and method for separating thin bottle flakes and label paper. technical background [0002] In the chemical fiber industry, a large part of the raw material is PET bottle flakes, but the general bottle is covered with a layer of label paper, so the paper needs to be peeled off manually, and the bottle flakes and label paper can be separated by careful selection. There is also an automatic paper stripper now, but it can only peel off the flattened bottle. If the bottle is packed and compressed before entering the paper stripper, the separation effect will be greatly reduced. We directly crush the whole bottle with label paper, and then send the crushed bottle flakes containing label paper to the blowing device, because most of the bottle flakes have a higher specific gravity than the label paper, so most bottle flakes and The label paper is sepa...

AI Technical Summary

Problems solved by technology

We directly crush the whole bottle with label paper, and then send the crushed bottle flakes containing label paper to the blowing device, because most of the bottle flakes have a higher specific gravity than the label paper, so most bottle flakes and The label paper is separated, but there is still a part of the relatively thin bottle flakes. The specific gravity of this part is not much different from that of the label paper, and it is difficult to separate it by blowing.
