On-line replacing method for extrusion roll of fiber spinning traction feeding machine

Abstract

The invention relates to an on-line replacing method for an extrusion roll of a fiber spinning traction feeding machine, in particular to the on-line replacing method for the extrusion roll of the traction feeding machine in the dry-method spinning process of acrylon, belonging to a fiber spinning conveying device. The on-line replacing method is characterized in that: when the extrusion roll has faults, an extrusion device special for maintenance is used to temporarily replace the extrusion function of the traditional extrusion roll having faults to maintain the normal operation of the fiber spinning traction feeding machine; and according to the extrusion device special for maintenance, a tray 4 on which an extrusion roll 1 special for maintenance is fixed penetrates through a fixed bolt groove in the middle of the tray through a tray fixing bolt 6 and is fixed on a traditional serially-connected roll shaft seat, thus the operation for on-line replacement for the extrusion roll can be finished and the aim of the on-line replacement for the extrusion roll can be achieved. The invention provides the method for realizing the on-line replacement for the extrusion roll of the traction feeding machine under the state of maintaining the normal operation of the fiber spinning production device; and the on-line replacing method is suitable for the one-line replacement of the extrusion roll of the traction feeding machine for the fiber spinning device using belt clamping force conveying equipment.

Description

technical field [0001] The invention relates to an online replacement method for extrusion rollers of a fiber spinning drawing and feeding machine. It belongs to the fiber spinning conveying device. It particularly relates to an online replacement method for extrusion rollers of a traction feeder in a dry acrylic fiber spinning process. Background technique [0002] The traction feeder is the key equipment in the dry-process acrylic fiber spinning process. Taking the water-phase precipitation polymerization-DMF two-step dry-process acrylic fiber production device introduced by DuPont in the United States in the 1980s as an example, each spinning machine includes 14 spinning positions share a traction-feeding machine. As one of the main components of the traction-feeding machine, the squeeze roller is used to exert a certain pressure on the tow through the transmission belt to make the gap between the transmission belt and the tow Appropriate friction is generated so that t...

Problems solved by technology

[0003] During the replacement of the spare table, the entire fiber spinning device will stop running, which shortens the running time of the spinning equipment and reduces the spinning production capacity; the time for parking and maintenance is tight and the tasks are heavy, which increases the labor intensity of the maintenance workers; increases the maintenance cost, which affects the economics of the entire plant
