Multi-feedback input type rolling-up tension control device

Abstract

The invention discloses a receiving tension control device with multiple feedback inputs, which comprises a guide roller, a tension sensor and a tension controller, one side of the guide roller is provided with a nip roller, and one side of the nip roller is arranged The tension sensor, the tension sensor is connected to the tension controller, the tension controller is provided with a display screen, the display screen is provided with a power switch, and one side of the power switch is provided with a function key, A frequency converter is connected to one side of the tension controller, and a servo motor is connected to one side of the frequency converter, and a receiving shaft is installed on the servo motor, and a material roll is arranged on the receiving shaft. The beneficial effect is that the tension parameter can be set automatically and manually, and the acceleration and deceleration of the servo motor can be automatically adjusted according to the tension parameter, so as to ensure uniform material collection and a high degree of automation.

Description

technical field [0001] The invention relates to the field of material receiving tension control, in particular to a material receiving tension control device with multiple feedback inputs. Background technique [0002] Winding is a very important process in wire and cable, textile, metal processing, papermaking and other processing. When the product is wound, the diameter of the reel gradually increases. It is very important to keep the tension of the rolled product constant during the whole process. If the tension is too high, the diameter of the wire will be thinned or even broken, or the thickness of the product will be uneven. If the tension is too small, it will cause winding slack. In order to keep the steel strip straight during the rolling process of the cold rolling production line, a certain tension must be maintained for both winding and unwinding, especially when the winding tension is not enough. The product is almost impossible to pack and handle. As the coil...

Problems solved by technology

When the product is wound, the diameter of the reel gradually increases. It is very important to keep the tension of the rolled product constant during the whole process. If the tension is too high, the diameter of the wire will be thinned or even broken, or the thickness of the product will be uneven. If the tension is too small, it may cause winding slack. In order to keep the steel strip straight during the rolling process of the cold rolling production line, a certain tension must be maintained for both winding and unwinding, especially when the winding tension is insufficient. Product is almost impossible to pack and handle

As the winding diameter increases, the tension of the winding part also increases. At this time, the speed must be lowered to meet the production needs. If the speed is not reduced at this time, the tension of the steel coil will be too large, and it will be broken or even burned. Bad motor and damage to other mechanical parts

The ordinary manual control is to adjust the manual power supply device by the operator when the roll diameter changes to a certain stage during the winding process, so as to achieve the purpose of controlling the tension. The degree of automation is low, and it is easy to cause uneven winding.
