【Stepless Speed ​​Adjustment】Stepless speed adjustment knob, 1-11 gears self-adjusting knob, can adjust the speed of the rewinder according to the speed of the printer. After the speed is adjusted, it will adapt to the speed of the printer. 【Intelligent Adjustment Lever】When the printer speed is too fast, the pressure lever automatically rises and the paper automatically stops rewinding to protect the print head and ensure that the pressure lever does not damage the print head. 【Autonomous Replacement】Hand-rolling will damage the labels, but this one will not waste every label, and the mold card can be replaced at will, which can match more printer models. 【Design】One machine can handle all rewinding operations and can be used with a variety of printers, It does not take up space, is easy to carry, and is durable. 【Applicable scenarios】Applicable to electronics factories, logistics centers, clothing factories.
