Description

TECHNICAL FIELD

[0001] The utility model relates to steel wire pay-off device technical field especially relates to a steel wire electrolytic phosphorization constant tension pay-off support. BACKGROUND

[0002] In the steel wire electrolytic phosphorization production, the steel wire needs to keep a certain tension, so as to avoid the pay-off device rotating too fast and causing the steel wire to be thrown, the line to be thrown, the line to be disorderly, and the pay-off machine to be able to stop rotating in a certain time, otherwise the steel wire will be disorderly, thrown.

[0003] At present, there are mainly two kinds of adjustment modes for the pay-off tension in the steel wire pay-off production process: the first one is the active pay-off device, which controls the steel wire pay-off speed through the motor and the frequency converter, so as to keep the steel wire tension, and the advantage is stable operation, and the disadvantage is high equipment cost and increased production power consumption; the second one is to adjust the tension by using the friction brake, which brakes the steel wire pay-off device by using the friction force between the brake belt (sheet) and the brake wheel (disc), so as to adjust the steel wire tension, and the advantage is simple structure, and the disadvantage is that the same braking force will produce different steel wire tensions due to the changes of the mass and speed of the pay-off wheel in the pay-off process, resulting in poor stability of the steel wire tension; serious heating, which easily causes high temperature of the pay-off device, shortens the service life of the equipment and causes brake failure; the third one is that the brake belt (sheet) and the brake wheel (disc) are easy to wear and damage, and a certain amount of dust will be produced in the friction process of the brake belt (sheet) and the brake wheel (disc), which affects the production environment.

[0004] The steel wire pay-off constant tension device mainly solves the phenomena of steel wire relaxation, I-beam line throwing, line disorder and steel wire breakage caused by frequent tension fluctuations in the steel wire pay-off process, so as to meet the production requirements and improve the product quality.

[0005] A constant tension pay-off device is disclosed in Chinese Patent No. 2024208829375, which includes a workbench, a pay-off roller rotatably connected to one end of the workbench, and a take-up roller rotatably connected to the other end of the workbench. A first mounting plate is provided on the workbench, and a housing is provided on the first mounting plate. A tensioning assembly is provided inside the housing. The tensioning assembly includes a compensation rod slidingly connected inside the housing. A spring is provided on the outer surface of the compensation rod. One end of the spring is connected to the first mounting plate, and the other end of the spring is connected to a pressing plate. The pressing plate is provided on the surface of the compensation rod. The technical solution makes each steel wire rope in a tensioned state through the tensioning assembly, reduces the possibility of steel wire rope relaxation, and thus ensures that the take-up tension of each steel wire rope is the same, thereby improving the production quality of the brake wire to a certain extent. However, the adjustment and control of the pay-off speed is controlled by the friction force between the steel wire rope and the threading hole and the movement of the compensation rod. This adjustment method conforms to the second adjustment method mentioned above. During the threading process, the tension of the steel wire rope is different, resulting in poor stability of the steel wire tension. Moreover, the friction of the steel wire rope on the threading hole causes wear of the compensation rod, the braking force of the threading device decreases, and after shutdown, the problems of disordered threading and slippage of the spool or other threading devices occur.
