Abstract

A spindle tension control apparatus, a payoff tension control system and a payoff tension control method. The spindle tension control apparatus (1) comprises: a swing roller (2), a swing arm (3), a mandrel (4), a first support mechanism (50) and a second support mechanism (51); the mandrel (4) is provided on the first support mechanism (50), and the swing arm (3) is provided on the second support mechanism (51); one end (31) of the swing arm (3) is connected to the swing roller (2), and the other end (32) of the swing arm (3) is provided with a rotational center hole or a rotational center shaft (321); and the spindle tension control apparatus (1) further comprises a tension control assembly which is provided with an input end (61) and an output end (62), the input end (61) is connected to the mandrel (4) and is configured to move synchronously together with the mandrel, and the output end (62) is connected to the rotational center hole or the rotational center shaft (321) of the swing arm (3) and is configured to move synchronously together with the swing arm. The payoff tension control system comprises a spindle tension control apparatus (1), an external power source and a controller, and the payoff tension control method is applied to the payoff tension control system.
