Description

Technical Field

[0001] The utility model relates to the field of carbon fiber production, in particular to an automatic and efficient carbon fiber precursor yarn withdrawal device. Background Art

[0002] Carbon fiber is very popular in high-end products such as aerospace engineering, civil engineering, and competitive sports products due to its excellent properties such as high hardness, high strength, high chemical resistance, light weight, and high temperature resistance. It is known as the most vital new material in the 21st century.

[0003] In the existing production process of carbon fiber filaments, the raw filaments are usually wound on fiber paper rolls or plastic rolls according to a certain weight (below 200 kg), and placed on the raw filament warehouse rack after being spooled. When carbonization is required, a manual cart is used to transport it to the carbonization unwinding rack; during transportation, the surface stress is relaxed; and during carbonization unwinding, the filament bundle is easy to produce filaments. Unwinding is the first process in carbon fiber production, and the quality of the raw filament plays a decisive role in the qualified rate and quality of the carbon fiber. However, the traditional carbon fiber raw filament unwinding device can easily cause problems such as scraping, sticking, and wear. The raw filament itself is easily damaged during transportation and unwinding. This phenomenon not only requires a lot of labor and time to deal with the hairy filaments, but also affects the stability of carbon fiber performance, greatly reduces production efficiency, and increases production costs. At present, there is no automatic and efficient unwinding device for carbon fiber raw filaments. Utility Model Content

[0004] In order to overcome the problems existing in the current wire withdrawal process, the utility model provides an automated and efficient wire withdrawal device for carbon fiber precursor, so as to solve the problems that traditional carbon fiber precursor wire withdrawal devices are prone to cause wire scraping, wire sticking, wear and tear, and the loading and unloading of the devices are time-consuming and labor-intensive, which affects the stability of the carbon fiber performance.

[0005] The technical solution to achieve the technical problem solved by the utility model is as follows:

[0006] An automatic and efficient carbon fiber precursor yarn withdrawal device;

[0007] There is a guide rail at the bottom of the wire withdrawal device, on which a pulley and a driving wheel are installed.

[0008] The winding rack enters the wire withdrawal device from the placement area. The winding rack has an NFC device, and the corresponding raw wire information can be directly obtained and stored in the information display device when it is in the placement area;

[0009] The winding frame passes through the pulley on the guide rail, and each of the three driven wheels is followed by a driving wheel, and a group of four can drive the winding frame to move to the specified position;

[0010] The carbon fiber precursor is led out from the guide roller to the guide wheel. After the carbon fiber precursor is led out from the guide wheel, it is introduced into the subsequent drafting area to start unwinding. There is a weight sensor in the corresponding bottom area of ​​the winding machine, and the operating status can be monitored in real time on the information display device;

[0011] After the original silk of the winding rack is unwound, the information display screen device can control the winding rack to be sent to the storage area and the placement area through the slide rail.

[0012] The bottom of the winding frame is equipped with a weight sensor, which displays the weight of the original silk in real time on the control device. The information display device can adjust the winding frame's wire withdrawal speed, and the control range is 0-20m / min.

[0013] The winding rack can hold carbon fiber raw yarn products of different tow specifications. The diameter of the product is 600㎜-1500㎜ and the weight is 0-1000Kg.

[0014] The information display screen device can control the position of each winding rack through the driving device.

[0015] Furthermore, the pulley at the bottom of the winding frame can be driven to transport the winding frame to a specified position through a slide rail.

[0016] Furthermore, when a winding rack is placed at the entrance, it can be transported to a designated location through the information display screen device; when the original wire of the winding rack is withdrawn, the winding rack can be moved to the placement area of ​​the withdrawn wire device.

[0017] Each winding rack is equipped with an NFC device (near field wireless communication device), which can synchronize the original silk information to the NFC device. The control system can obtain the corresponding carbon fiber original silk quality information in the placement area, and synchronize the withdrawn silk information with the winding rack NFC device after the withdrawn silk is completed.

[0018] The information display screen device can check the operating status of the wire withdrawal device, the location of each winding rack and the remaining raw wire amount.

[0019] Compared with the prior art, the utility model has significant advantages:

[0020] This carbon fiber unwinding rack system can reduce the workload of employees, reduce the downtime of the carbonization furnace, reduce waste, and improve work efficiency, providing better protection for the carbon fiber pre-oxidation process.
