Carbon fiber spreading frame grouped torque control device and control method thereof

Abstract

The invention relates to the technical field of motors, in particular to a carbon fiber spreading frame grouped torque control device. The device includes a rack, spools, a fiber spreading device, a yarn guide device and a yarn storage device. The rack is provided with at least two layers of support frames used for installation of the spools, the number of the spools arranged on each layer of thesupport frames is same, and the number is more than or equal to two. The spools, same in arrangement position, in each spool layer reach the yarn guide device at the same angle and are transferred tothe fiber spreading device through gathering of the yarn guide device, and after fiber spreading, yarn reaches the yarn storage device for storage. According to the technical scheme, the motor controlcost is effectively reduced, and labor and time cost brought by manual debugging are saved. Moreover, the invention further requests a control method for the carbon fiber spreading frame grouped torque control device.

Description

Technical field [0001] The invention relates to the technical field of motors, in particular to a grouping torque control device and a control method of a carbon fiber spreading creel. Background technique [0002] The carbon fiber or glass fiber multi-axial warp knitting machine needs to maintain a constant yarn tension during the cutting and weaving process, so a torque motor and a control device are required during the unwinding process. At present, domestic torque motors generally use torque controllers. This type of controller needs to adjust the voltage on site and control the output torque to maintain the constant tension of the yarn. This type is only suitable for a single motor to control the tension, and a yarn unwinding A few dozens of torque motors are needed for a rack, and one or two hundred torque motors are needed. The commissioning of each unit will waste a lot of labor and time, which will greatly increase the implementation cost. [0003] In view of the above pr...

This kind of controller needs to adjust the voltage on site and control the output torque to maintain the constant tension of the yarn. This is only suitable for a single motor to control the tension, and a yarn unwinding At least dozens of torque motors are needed on the rack, and as many as one or two hundred torque motors. It will waste a lot of labor and time to debug each one, which will greatly increase the implementation cost
