Description

Star roller conveyor

Technical Field

The present disclosure relates to a star roller conveyor.

Background

The statements herein merely provide background information related to the present disclosure and may not necessarily constitute prior art.

The star roller conveyor is a common device in the tobacco production industry, is generally placed after a loosening and moisture regaining process of a tobacco leaf process section in a tobacco shred manufacturing workshop and is used for spreading materials, removing tobacco leaf caking which is not loosened completely and hanging and removing hemp threads in the tobacco leaves in the process of conveying the materials so as to meet the process requirements of subsequent processing of the tobacco leaves.

In the related art, the star roller conveyor runs through the process that the sheet tobacco is conveyed by a front conveying belt, the tobacco blocks fall onto the star roller conveyor and firstly pass through a hemp yarn roller at the front end and then run to a star roller at the rear section, all rollers are driven by a driving motor through chain wheels with the same diameter and the same size, and the rollers rotate in the same direction at the same rotating speed during operation. The tobacco flakes fall onto the first roller firstly, after rotating for a certain angle, the tobacco flakes roll onto the next roller, and are repeatedly transferred according to the roller, loose tobacco flakes move and fall simultaneously in the process, and the tobacco flakes are evenly spread on a loose tobacco flake conveying belt arranged below the roller and enter downstream equipment through a loose tobacco flake discharging port

Because the rollers can only run at the same speed, the phenomenon that the tobacco blocks are stuck to a new roller at the front end often occurs; if the running speed needs to be increased, the tobacco blocks run over the star rollers too fast, the retention time is short, loose sheet tobacco cannot fall from the space between the star rollers, and the tobacco block leaf content is high; if reduce the functioning speed, lead to the smoked sheet to drop easily from between the front segment roller again, and easily block dead star roller to lead to the smoked sheet to reject inefficiency.
