technical field

The utility model relates to the field of carbon fiber manufacturing, in particular to an assembleable wire-drawing plate used in the carbon fiber chopping process, which improves the wire-drawing efficiency.

Background technique

The carbon fiber chopped process is an important link in the field of carbon fiber manufacturing. After carbon fiber is chopped, carbon fiber reinforced composite materials with high strength, high modulus, small specific gravity and strong stability can be prepared, which are widely used in aerospace and military fields.

Before the carbon fiber is chopped, it has to go through pretreatment processes such as sizing and oven drying. Before completing these pretreatment processes, it is necessary to complete a complicated and tedious wire drawing process to pull the carbon fiber tow from the creel to the sizing device and oven. , and finally to the chopping device. At present, the industry often adopts the method of pulling single tows in place sequentially to lead the wires. This method is prone to wire entanglement and the efficiency is not high. When it is necessary to increase the carbon fiber tow station or readjust the station, it is necessary to re-conduct the wire drawing process. Therefore, in the wire drawing process, it is necessary to ensure that there is no mutual interference between the carbon fiber tows, so that the tows in each process can be transported stably until the chopping is completed. Moreover, in the production process of chopped carbon fiber, the wire drawing process must be shut down to stop production. Therefore, minimizing the time spent in the wire drawing process is conducive to improving production efficiency and reducing unnecessary cost losses.

detailed description

In order to further understand the utility model, the utility model will be further described below in conjunction with the accompanying drawings and embodiments, but it should be noted that the protection scope of the utility model is not limited to the range described in the embodiments.

As shown in Figure 1, an assembleable wire guide plate for carbon fiber chopping process includes a rectangular plate body made of plastic or metal, on which a number of vertical plate bodies are arranged at equal intervals along a straight line. The through hole facilitates the fixing of the carbon fiber tows and prevents the tows from interfering with each other. The through holes include two thread-leading holes 1 and ten holes 2 for thread-leading. The diameters of the thread-leading hole 1 and the thread-to-be-drawn hole 2 are 3-10mm, which is beneficial for threading carbon fiber bundles. The two ends of the plate body are provided with assembly parts 3 for connecting another wire guide plate that can be assembled. The assembly parts 3 include wedge-shaped pieces and wedge-shaped grooves respectively arranged at both ends of the rectangular plate body. There is a transition fit between the two wire guide plates that can be assembled.
