An ultra-low tension doffing device

Abstract

The invention relates to an ultralow tension cropping device, comprising a low tension cloth feeding mechanism, a conveying mechanism and a cloth swinging mechanism; the low tension cloth feeding mechanism comprises a drive motor, a first drive roll, a second drive roll, a tension sensor and a bending roll; the drive motor drives the first drive roll to enable cloth to pass by the first drive roll, the second drive roll, the tension sensor and the bending roll in sequence to enter the conveying mechanism; the conveying mechanism comprises a conveyor belt, a driving roll and a driven roll; the driving roll and the driven roll are erected on a mounting beam; the driving roll is driven by a conveyor belt motor through gear meshing, the inside of the conveyor belt is supported by a support roll, and the outside of the conveyor belt is tensioned by a tensioning roll; the cloth swinging mechanism comprises a swing arm and a cloth guide roll, the swing arm is hoisted at two ends of the driving roll and a mandrel, the cloth guide roll is erected on the swing arm, and the mandrel is driven by a cloth swinging motor. The ultralow tension cropping device has the advantages of no cropping indentations, no wrinkles and energy saving.

Description

technical field [0001] The invention relates to a cloth dropping device of a textile machine. Background technique [0002] The existing cloth doffing device of the sanding machine uses a driving roller with a relatively high tension to drive the cloth at the doffing place of the cloth, and the cloth is pulled tightly to drop the cloth, so that the edge of the cloth will be pressed out a lot due to the tension Indentations, and these indentations are difficult to eliminate, seriously affect the appearance and quality of the cloth; and if the driving roller has no tension or the tension is too small, the cloth in the middle of the driving roller will also wrinkle due to relaxation. Contents of the invention [0003] The object of the present invention is to solve the above existing problems and provide an ultra-low tension cloth doffing device with no indentation, no wrinkles and energy saving. [0004] The purpose of the present invention is achieved in that it includes a...
