Roller and linen drying machine comprising roller

Abstract

The invention provides a roller. The roller is of a tube structure with openings in the two ends. A plurality of stop blocks are arranged on the inner wall of the roller, a plurality of through holesfor allowing hot steam to enter and exit are formed in the roller wall of the roller in a penetrating mode, and the multiple stop blocks are evenly distributed in the circumferential direction of theroller. Each stop block comprises a first spiral block, a second spiral block and a third spiral block, the first spiral blocks, the second spiral blocks and the third spiral blocks are correspondingly and spirally arranged along the inner wall of the roller, the first spiral blocks are located at the first end of the roller, the second spiral blocks are located at the second end of the roller, and the third spiral blocks are located between the first spiral blocks and the second spiral blocks. The first ends of the third spiral blocks are connected with the first spiral blocks, the second ends of the third spiral blocks are connected with the second spiral blocks, and the screw pitch of the first spiral blocks and the screw pitch of the second spiral blocks are both smaller than that of the third spiral blocks. Continuous feeding and continuous discharging of dried linen can be achieved through the roller, so that the drying efficiency of a linen drying machine is higher.

Description

technical field [0001] The invention relates to the technical field of linen drying, in particular to a drum and a linen dryer including the drum. Background technique [0002] A linen dryer in the prior art usually includes a casing, a drum and an exhaust device. The drum is rotatably arranged in the casing, and an opening is provided on the casing, and the opening communicates with the inside of the drum for placing or taking out linen from the opening. The outer peripheral wall of the drum is provided with a through hole for heating steam to enter and exit. Under the action of the exhaust device, the hot steam enters the inside of the shell and then enters the drum to heat and dry the clothes in the drum. However, this linen dryer has only one opening, and both feeding and discharging are carried out at this opening. After drying, it is necessary to stop the linen dryer, and then take out the linen in the drum. And put in the new linen to be dried, which cannot be fed a...

AI Technical Summary

Problems solved by technology

However, this linen dryer has only one opening, and both feeding and discharging are carried out at this opening. After drying, it is necessary to stop the linen dryer, and then take out the linen in the drum. And put in new linen to be dried, unable to continuously feed and discharge, resulting in low drying efficiency, unable to meet the drying needs of the linen washing production line

Therefore, how to solve the problem of low drying efficiency of linen dryers in the prior art is a set of technical problems urgently needed by those skilled in the art.
