Tow guide roller and application thereof

Abstract

The invention provides a tow guide roller. The tow guide roller comprises a tow guide shell, an inner lining, two baffle rings, a shaft, two bearing packs, two choke plugs, two shaft sleeves, two adjusting screws and two locking screws, wherein the tow guide shell is a ceramic pipe or a porcelain enamel metal pipe; the wall thickness of the tow guide shell is between 2 and 8mm; two circles of channels can be reserved on the inner wall of the inner lining, so that the two baffle rings can be arranged in the channels; the inner lining is connected inside the tow guide shell; the two bearing packs are arranged at the two ends of the shaft respectively; the two choke plugs are arranged at the two ends of a bearing; the two shaft sleeves are sleeved on the outer sides of the two choke plugs and partially extend into the two ends of the tow guide shell respectively; the two adjusting screws are arranged on the two shaft sleeves; and the tow guide shell is in transition fit or interference fit with the inner lining, the inner lining is in transition fit or interference fit with a bearing outer shell, a bearing inner shell is in transition fit or interference fit with the shaft, and the tow guide shell is in clearance fit with the shaft sleeves. The tow guide shell has high wear resistance and heat resistance and long service life, flying of a tow can be reduced, and the quality of the tow can be guaranteed. The tow guide roller can be used for a production line of acetate fibers.

Description

technical field [0001] The invention relates to a guide roller in fiber tow production, especially a tow guide roller with better wear resistance and its application. Background technique [0002] Usually, the godet rollers used in the fiber manufacturing industries such as acetate fiber, polypropylene fiber, and cotton fiber are ordinary metal rollers, and more complex metal rollers have a combined structure of a rotating shaft, a bearing and a metal rotating shell. Their common defect is that the surface is not wear-resistant, and the fiber tow is easy to pull, and it is easy to conduct heat to the tow, which affects the quality of the tow. [0003] The document with the patent application number of CN201020191371.X provides a self-positioning structure of the guide wire ceramic part of the overfeed roller of the two-for-one twister. Two ceramic seats opposite to each other are installed on the shaft of the clamping part, and the guide wire porcelain part is uniform. moun...

AI Technical Summary

Problems solved by technology

Its structure is relatively simple, lacking parts such as bearings, and it cannot guarantee flexible rotation; in addition, the electrochemical coating ceramic layer on its surface has weak bonding force, and the ceramic layer is very thin, which cannot meet the long-term high-load operation guidance needs
