Abstract

Furthermore, the infrared probe monitors the guide rollers, allowing for precise control of the winding speed and number of turns. The infrared probe can also detect the number of turns of the guide rollers and record their usage daily, facilitating maintenance or replacement and ensuring the neatness and precision of the carbon fiber during movement.

An infrared detection frame structure 8 is installed in the upper right corner of the inside of the yarn unfolding shell 3. A reed door 9 is fixedly installed in the upper left corner of the inside of the yarn unfolding shell 3.

A fixing plate 82 is fixedly installed on the right side of the controller 81. A wire 83 and an adjustment plate 85 are plugged into the interface of the controller 81. A support frame 84 is fixedly installed on the lower part of the fixing plate 82. The support frame 84 and the adjustment plate 85 are connected by bolts.

An infrared probe 87 is fixedly installed on the other end of the wire 83.
[0028] In this embodiment, specifically, the left side of the housing 51 is fixedly installed on the right side of the yarn spreading housing 3.
[0029] In this embodiment, specifically, the right side of the housing 51 is fixedly installed on the left side of the carbon fiber unwinding device 1.

[0036] Working principle
[0037] In this invention, during use, the carbon fiber inside the carbon fiber unwinding device 1 is first connected to the traction device. The traction device slowly fills the carbon fiber into the carbon fiber feed pipe 52. The stainless steel guide rail 53 improves the smoothness and stability of the carbon fiber movement. The carbon fiber feed pipe 52 protects the carbon fiber and prevents it from being disturbed or damaged during winding, reducing costs. The carbon fiber is then transported to the next stage via the guide roller and the yarn separating traction machine 6. If a problem occurs with the carbon fiber, it will cause a change in the position of the guide roller. At this time, the guide roller is monitored by the infrared probe 87. When the roller changes position, the data is transmitted to the controller 81. The controller 81 then disconnects the power to the traction device, allowing staff to inspect and eliminate any potential problems before restarting the traction device. This facilitates subsequent processing by staff, enabling precise control of the winding speed and number of turns. Furthermore, the infrared probe 87 can detect the number of turns of the guide roller's infrared generator. After the guide roller completes one rotation, the infrared receiver works in conjunction with the infrared probe 87 to facilitate daily recording of the guide roller's usage. This allows for convenient maintenance or replacement of the guide roller, ensuring the neatness and precision of the carbon fiber movement.
