Mechanism for cleaning needle roller of winnowing machine

Abstract

The invention provides a mechanism for cleaning a needle roller of a winnowing machine. The mechanism for cleaning the needle roller of the winnowing machine comprises a scraping knife shaft, scrapingknives, a fixing frame and a rotary driving mechanism, wherein the scraping knife shaft is arranged under the needle roller; the rotary driving mechanism is used for driving the scraping knife shaftto rotate; the scraping knife shaft and the needle roller are arranged in a way of being parallel to each other; a plurality of scraping knives are arranged in the axial direction of the scraping knife shaft; the point end part of each scraping knife is near the surface of the needle roller; the first end of the scraping knife shaft passes through a first connecting hole of the fixing frame; the second end of the scraping knife shaft passes through a second connecting hole of the fixing frame; the scraping knife shaft is respectively and rotatablely connected with the first connecting hole andthe second connecting hole; and the first end is connected with the rotary driving mechanism. The mechanism for cleaning the needle roller of the winnowing machine has the advantages that materials and sundries attached to the surface of the needle roller can be better cleaned; and the needle roller cleaning mechanism of the winnowing machine and a cleaning roller can be used at the same time, sothat a better cleaning effect is achieved on the needle roller.

Description

technical field [0001] The invention relates to the technical field of tobacco processing equipment, in particular to a needle roller cleaning mechanism of a winnowing machine. Background technique [0002] The needle roller in the looser used in the air separation machine in the tobacco industry is to loosen the agglomerated shredded tobacco after air selection, and provide loose shredded tobacco for the subsequent process. Since the surface of the needle roll is often mixed with shredded tobacco and other sundries mixed in the shredded tobacco, a cleaning roller is usually arranged in the in-situ winnowing machine for cleaning the surface of the needle roll. like Figure 1 to Figure 3 As shown, the material 11 falls to the surface of the needle roller 15 of the looser 12, and the needle bar 16 on the needle roller 15 loosens the material, and after loosening, it falls into the belt conveyor 13 and is transported to the next process, wherein the cleaning roller 14 Clean ou...

Problems solved by technology

However, the cleaning roller can only clean the materials and sundries close to it, and cannot clean the materials and sundries close to the surface of the needle roll, so that the surface of the needle roll cannot be cleaned well. Therefore, how to make the needle roll Obtaining a better cleaning of the surface has become an urgent technical problem for those skilled in the art
