Abstract
Description
Technical Field
[0001] This utility model relates to a warping machine, and more particularly to a tension control device for a carbon fiber spreading warping machine, belonging to the field of textile equipment technology. Background Technology
[0002] When the warping machine is working, the carbon fiber yarn is passively unwinding from the wound yarn bobbin, passing through the guide tube and the yarn separating reed in sequence, and then entering the area of the vibrating device and the heating device. After being vibrated at high frequency by the vibrating device and heated by the heating device, the yarn is spread into the traction device, and finally wound onto the take-up roller by the take-up device.
[0003] Because the strip-shaped carbon fiber yarn bundles often exhibit bending, unevenness, and inconsistent widths after being formed into bobbins and then unwound, the tension of the carbon fiber yarn is adjusted manually during the fiber spreading process. This results in inconsistent and uneven tension of the carbon fiber yarn wound on the take-up roller, causing the warping quality to fail to meet the requirements of subsequent weaving. Summary of the Invention
[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a tension control device for a carbon fiber spreading and warping machine that can automatically adjust the tension of carbon fiber yarn during the spreading process to ensure that the tension of the carbon fiber yarn wound on the take-up roller is uniform.
[0005] To solve the above-mentioned technical problems, this utility model employs a tension control device for a carbon fiber warping machine, comprising several yarn bobbins wound with carbon fiber yarn, and a reed separator, a vibrating device, a pulling device, and a winding device arranged sequentially along the running path of the unwound carbon fiber yarn on the yarn bobbins. The pulling device includes a first motor and a pulling roller driven by the first motor, and the winding device includes a second motor and a winding roller driven by the second motor. The first motor and the second motor are connected to the central processing unit of the warping machine. A first roller and a second roller are arranged sequentially along the running path of the carbon fiber yarn between the reed separator and the vibrating device, with the first roller and the second roller arranged vertically at intervals. The first roller is powered by a third motor. The machine is driven by a third motor. The second roller is driven by a fourth motor. A first guide roller is set on the carbon fiber yarn running path between the vibrating device and the traction device. A first pressure sensor for measuring the tension of the carbon fiber yarn passing through the first guide roller is installed at one or both ends of the first guide roller. A second guide roller is set on the carbon fiber yarn running path between the traction device and the winding device. A second pressure sensor for measuring the tension of the carbon fiber yarn passing through the second guide roller is installed at one or both ends of the second guide roller. The first roller, the second roller, the first guide roller, and the second guide roller are arranged along the width of the carbon fiber yarn. The third motor, the fourth motor, the first pressure sensor, and the second pressure sensor are connected to the central processing unit of the warping machine.
[0006] In a preferred embodiment of this utility model, first bearing seats are provided at both ends of the first roller, and the shaft end of the first roller is rotatably connected to the first bearing seat. The first bearing seat is fixedly installed on the frame of the warping machine. Second bearing seats are provided at both ends of the second roller, and the shaft end of the second roller is rotatably connected to the second bearing seat. The second bearing seat is installed on the frame of the warping machine in an adjustable vertical and / or front-back position.
[0007] In a preferred embodiment of the present invention, second bearing seats are provided at both ends of the second roller, and the shaft end of the second roller is rotatably connected to the second bearing seat. The second bearing seat is fixedly installed on the frame of the warping machine. First bearing seats are provided at both ends of the first roller, and the shaft end of the first roller is rotatably connected to the first bearing seat. The first bearing seat is installed on the frame of the warping machine in an adjustable manner in terms of vertical position and / or front-back position.
[0008] In a preferred embodiment of this utility model, a heating device for heating the carbon fiber yarn is further provided on the running path of the carbon fiber yarn between the vibrating device and the pulling device. The first guide roller is disposed between the vibrating device and the heating device, and the first guide roller is located behind the heating device. The rotational speed of the second roller is greater than that of the first roller.
[0009] In a preferred embodiment of this utility model, the central processing unit of the warping machine includes an industrial control computer, a programmable logic controller (PLC), or a distributed control system (DCS).
[0010] By adopting the above structure, this utility model has the following beneficial effects:
[0011] This invention includes a first roller and a second roller between the yarn separating reed and the vibrating device. The first roller is driven by a third motor, and the second roller is driven by a fourth motor. A first guide roller is positioned between the vibrating device and the traction device, and a first pressure sensor is installed at one or both ends of the first guide roller. A second guide roller is positioned between the traction device and the winding device, and a second pressure sensor is installed at one or both ends of the second guide roller. During the carbon fiber spreading process, a constant speed is first set on the first motor of the traction device to start the machine, unwinding the carbon fiber yarn from the wound bobbin. The yarn then passes sequentially through the yarn separating reed, the first roller, and the second roller before entering the vibrating device and the first guide roller. Preferably, it then passes through a heating device before entering the traction device, and finally is wound onto the winding roller by the winding device. During the operation of the carbon fiber yarn, since the yarn bobbin passively unwinds, the central processing unit (CPU) controls the rotational speeds of the first and second rollers via the third and fourth motors, respectively. Preferably, the second roller's rotational speed is greater than the first roller's, meaning the second roller rotates faster than the first roller, ensuring the carbon fiber yarn between the two rollers remains taut. A first pressure sensor continuously monitors the tension value of the carbon fiber yarn as it passes the first guide roller and transmits this value to the CPU. If the CPU determines that the tension value is less than the process-set tension value, it controls the third and fourth motors to make the second roller's rotational speed greater than the first roller's speed until the tension value equals or falls within the process-set tension value range. If the CPU determines that the tension value is greater than the process-set tension value, it controls the fourth motor to reduce the tension. The second roller speed is slowed down to reduce the speed difference between the two rollers until the tension value equals or falls within the process-set tension value range. Simultaneously, the second pressure sensor detects the tension value of the carbon fiber yarn as it passes the second guide roller and transmits this value to the central processing unit (CPU). If the CPU determines that the tension value is less than the process-set tension value, it controls the second motor to increase the speed of the take-up roller until the tension value equals or falls within the process-set tension value range. If the CPU determines that the tension value is greater than the process-set tension value, it controls the second motor to decrease the speed of the take-up roller until the tension value equals or falls within the process-set tension value range. Through these control measures, this invention automatically adjusts the tension of the carbon fiber yarn, ensuring uniform tension of the carbon fiber yarn wound on the take-up roller.
[0012] This invention provides first bearing seats at both ends of the first roller, which are fixedly mounted on the frame of the warping machine. Second bearing seats are provided at both ends of the second roller, and their vertical and / or front-to-back positions are adjustable on the frame. This invention changes the wrap angle of the carbon fiber yarn as it passes through the second roller by adjusting its installation position, thereby adjusting the tension value of the carbon fiber yarn as it passes through the second guide roller. This further expands the adjustment range of the carbon fiber yarn tension value, making it more conducive to automatically adjusting the tension of the carbon fiber yarn and ensuring uniform tension of the carbon fiber yarn wound on the take-up roller.

[0026] As a preferred mode of operation of this utility model, see [link to relevant documentation].

After passing through the heating device 15, it enters the pulling device 3 and is finally wound onto the take-up roller 4-1 by the take-up device 4.
