Description

Automatic control system of carbon fiber yarn returning machine

Technical Field

The utility model relates to a carbon fiber production facility field says in detail a carbon fiber moves back yarn machine automatic control system.

Background

As is well known, carbon fibers have high specific strength, high specific modulus, high temperature resistance, corrosion resistance, fatigue resistance, creep resistance, electric conductivity and small thermal expansion coefficient, can be used as structural materials for bearing load and can also be used as functional materials for playing a role, and the development of the carbon fibers is rapid in the last decade. The yarn unwinding machine used in the carbon fiber production process is a passive yarn unwinding process controlled by a spring belt, a guide roller rotates under the friction traction of the belt, and the rotating speed is not stable, so that the tension of precursor is unstable, the quality of a product is greatly influenced, carbon fiber broken filaments are increased, and the yarn is frequently broken.

Disclosure of Invention

In order to overcome the defects of the prior art, the utility model provides a carbon fiber yarn returning machine automatic control system keeps constant and uniform of tension.

The utility model provides a technical scheme that its technical problem adopted is: an automatic control system of a carbon fiber yarn withdrawing machine is provided with a protofilament fiber cylinder and is characterized in that the protofilament fiber cylinder is driven by a servo motor, a first guide roller and a third guide roller which are axially parallel are horizontally arranged in front of the protofilament fiber cylinder, the upper roll surfaces of the first guide roller and the third guide roller are positioned on the same horizontal plane, a second guide roller which is parallel to the axis of the first guide roller and the third guide roller is arranged below the first guide roller and the third guide roller, a fourth guide roller which is parallel to the axis of the third guide roller is arranged in front of the third guide roller, a compression roller and a traction roller which are parallel to the axis of the fourth guide roller are arranged in front of the fourth guide roller, the compression roller and the traction roller are arranged up and down and are tangent to the roll surfaces, the tangent position of the compression roller and the traction roller is positioned on the same horizontal plane with the lower roll surface of the fourth guide roller and the lower roll surface of the second guide roller, a swing arm shaft is arranged behind the second guide roller, and the signal output end of the PLC controller controls the servo motor through the servo controller.

The beneficial effects of the utility model are that, tension can keep invariable, unified, prevents that broken filaments, disconnected silk phenomenon from appearing in the carbon fiber to improve product quality and production efficiency.

Drawings

The present invention will be further explained with reference to the drawings and examples.

Fig. 1 is a schematic structural diagram of the present invention.

In the figure, 1, a protofilament fiber cylinder, 2, a first guide roller, 3, a third guide roller, 4, a fourth guide roller, 5, a compression roller, 6, a traction roller, 7, a second guide roller, 8, a swing arm, 9, an angle sensor, 10, a PLC (programmable logic controller) and 11, a servo motor are arranged.

Detailed Description

As shown in figure 1, the utility model is provided with a raw silk fiber cylinder 1, the raw silk fiber cylinder 1 is driven by a servo motor 11, a first guide roller 2 and a third guide roller 3 which are parallel in the axial direction are horizontally arranged in front of the raw silk fiber cylinder 1, the upper roll surfaces of the first guide roller 2 and the third guide roller 3 are positioned at the same horizontal plane, a second guide roller 7 which is parallel to the axis is arranged below the first guide roller 2 and the third guide roller 3, a fourth guide roller 4 which is parallel to the axis is arranged in front of the third guide roller 3, a compression roller 5 and a traction roller 6 which are parallel to the axis are arranged in front of the fourth guide roller 4, the compression roller 5 and the traction roller 6 are arranged up and down and the roll surfaces are tangent, the tangent position of the compression roller 5 and the traction roller 6 is positioned at the same horizontal plane with the lower roll surface of the fourth guide roller 4 and the lower roll surface of the second guide roller 7, a swing arm shaft is arranged behind the second guide roller 7, the swing arm, the angle sensor 9 is connected with a signal input end of a PLC (programmable logic controller) 10 through a data line, and a signal output end of the PLC 10 controls the operation of a servo motor 11 through a servo controller.

The carbon fiber on the protofilament fiber cylinder 1 of the utility model enters the roller surface tangent part of the compression roller 5 and the traction roller 6 through the upper roller surface of the first guide roller 2, the lower roller surface of the second guide roller 7, the upper roller surface of the third guide roller 3 and the lower roller surface of the fourth guide roller 4, the traction roller 6 is driven by a motor, the carbon fiber precursor moves forward under the driving of the traction roller 6, an angle change signal collected by an angle sensor 9 on a swing arm shaft is input into a PLC (programmable logic controller) 10, the PLC 10 outputs an analog signal to a servo controller to carry out variable speed control on a servo motor 11, the precursor fiber cylinder 1 is driven to withdraw yarn, the angular speed of the servo motor 11 is changed, but the linear velocity is unchangeable, and the linear velocity tracks production speed, keeps unanimous with the linear velocity of carry over pinch rolls 6 department, adjusts the linear velocity of protofilament section of thick bamboo 1 and carry over pinch rolls 6 two departments stable, and tension is just stable, and the linear density and the quality of product are just stable.
