Seal device of clothes dryer roller end

Abstract

The invention relates to a sealing device of a dryer, in particular to a sealing device applied on the end of a dryer tumble. The sealing device comprises a tumble support ring; the side surface of the tumble support ring is evenly provided with a wear resistant elastic part; the end of the tumble is arranged on the tumble support ring; the end face of the tumble is axially extruded on the wear resistant elastic part. The wear resistant elastic part comprises a wear resistant felt layer and an elastic felt layer. Because of the structure, the sealing device on the end of the dryer tumble can seal evenly; in addition, in the device, a wear resistant double-layered sealing strip is adopted, so that the sealing device on the end of the tumble can automatically compensate the wear of the tumble to the sealing strip, and the sealing does not become uneven because of longer working time; the device has better sealing effect to the end of the dryer tumble.

Description

technical field [0001] The invention relates to a sealing device of a clothes dryer, in particular to a sealing device applied at the end of a drum of a clothes dryer. Background technique [0002] In the prior art, the sealing structure at the end of the traditional clothes dryer drum usually adopts radial seal, that is, the supporting ring of the clothes dryer drum is provided with a seal that contacts the end of the clothes dryer drum radially, but when the clothes are dried After the end of the machine drum is sleeved on the above-mentioned support ring, there will be radial assembly errors between them, which will lead to uneven sealing of the end of the drum, that is, the gap between the end of the drum and the support ring is small, and the gap in other parts is large; As the working time of the clothes dryer prolongs, the radial sealing strip at the end of the drum is constantly worn, which will cause the seal at the end of the drum to become more and more uneven. ...

AI Technical Summary

Problems solved by technology

[0004] The sealing devices at the end of the dryer drum disclosed in the above patent documents all use the radial seal at the end of the dryer drum. Although the above radial sealing structures all have a certain sealing effect on the end of the dryer drum, Since the drum of the dryer is set on the support ring, the axis of the drum and the center line of the support ring are not on the same straight line, resulting in the radial assembly error of the drum of the dryer, which makes the radial seal of the drum uneven and affects the protection of the drum. Sealing effect; with the extension of the working time of the clothes dryer, the radial sealing strip of the drum is continuously worn, which will cause the drum seal to become more and more uneven
