Magnetic damping tension precision adjustment device

Abstract

The invention relates to a magnetic damping tension precision adjustment device which is characterized in that a wrapping tape is arranged between belt-placing plates and fixed by a paper-pressing plate; the wrapping tape passes through a tension sensor after being pulled out; a damping plate is arranged under the belt-placing plate and fixed by a connecting piece; an autorotation body is provided with a rotating bearing and is provided with the damping plate, the belt-placing plate and the paper-pressing plate in sequence; an electromagnetic coil and the autorotation body are directly fixed on a revolution body which is installed on a main shaft; a controller is connected with a sliding ring on the main shaft by a lead; a carbon brush is arranged at the end part of the sliding ring which is arranged on the main shaft; and the main shaft and a director current motor are connected by a synchronous belt wheel. The invention has stable work, and convenient operation, strong safety and reliability, can directly and automatically adjust the tension and the tension angle without stop and can also improve the production efficiency.

Description

technical field [0001] The invention relates to a precision adjustment device for magnetic damping tension, in particular to a device for controlling the tension of wrapping when wrapping paper insulation. The magnetic powder damping technology used belongs to the technical field of winding wire wrapping. Background technique [0002] At present, in the production process of transposed wires, the insulating paper tape wrapping process uses a mechanical swing arm to control the braking force of the tape reel to achieve the stability of the wrapping tension of the paper tape. The change of the paper tape tension causes the swing arm to swing, and the swing of the swing arm causes the change of the tightness of the brake belt, so that the braking force of the tape reel changes. In this device, the reset tension of the swing arm is not constant because the swing arm resets using a tension spring. , which causes the pulling force of the paper tape to be constant, and the device a...

Problems solved by technology

The change of the paper tape tension causes the swing arm to swing, and the swing of the swing arm causes the change of the tightness of the brake belt, so that the braking force of the tape reel changes. In this device, the reset tension of the swing arm is not constant because the swing arm resets using a tension spring. , which causes the pulling force of the paper tape to be unable to be constant. At the same time, this device also has the disadvantages that the tension adjustment is difficult to quantify and the braking force between the brake belt and the brake wheel is unstable.

To sum up, because it is difficult to keep the tension of the paper tape constant during wrapping, which affects the stability of the production process and product quality, it is urgent to solve this problem in the industry
