Carbon fiber sizing equipment capable of being automatically adjusted along with change of sizing liquid amount

Abstract

The invention provides carbon fiber sizing equipment capable of being automatically adjusted along with changes of the amount of sizing liquid, and belongs to the technical field of carbon fiber sizing equipment.The carbon fiber sizing equipment comprises a sizing pool body, a sealed adjusting chamber is arranged on the sizing pool body, and a positive electrode plate and a negative electrode plate are symmetrically arranged on the inner side wall of the sealed adjusting chamber; the sealing adjusting chamber is communicated with a conversion chamber in a sealing mode, dielectric liquid is stored in the conversion chamber, and the conversion chamber is communicated with a first U-shaped pipe in a sealing mode. According to the carbon fiber sizing equipment capable of automatically adjusting along with the change of the amount of the sizing liquid, through the combined action of the U-shaped pipe I, the dielectric liquid and the sealed adjusting chamber, the problem that the sizing efficiency is reduced along with the reduction of the sizing liquid is effectively avoided, and the sizing degree of the same batch of carbon fibers is different due to the change of the pressure on the carbon fibers, so that the sizing efficiency is improved. And meanwhile, the problem that the sizing quality is influenced by deviation generated by sizing liquid fusion is avoided, so that the sizing quality and efficiency of the carbon fibers are greatly improved.

Description

technical field [0001] The invention relates to the technical field of carbon fiber sizing equipment, in particular to a carbon fiber sizing equipment that is automatically adjusted as the amount of sizing liquid changes. Background technique [0002] Carbon fiber refers to the fiber in which the carbon element in the chemical composition of the fiber accounts for more than 90% of the total mass. Due to the nature of the carbon body, the conditions for the production of carbon fiber are very harsh. Generally, the production process of carbon fiber mainly includes the preparation of raw silk, raw Oxidation of silk, carbonization or further graphitization of pre-oxidized silk, and post-treatment of carbon fiber. In the above-mentioned production and processing of carbon fiber, the post-treatment of carbon fiber in the last step has a relatively large impact on the quality of carbon fiber itself compared with the previous process. It is small and relatively low in difficulty an...

Problems solved by technology

[0004] However, in the current carbon fiber sizing treatment equipment, in order to ensure the effect of sizing, a pressure roller is generally installed in the sizing tank, and the position of the pressure roller is generally fixed, and it is usually set at the lower position in the sizing tank. With continuous sizing, the sizing liquid in the sizing tank is getting less and less. Because the pressure roller is fixed, there will be two problems. One is that with the reduction of sizing liquid, the amount of sizing carbon fiber per unit time is also increasing. less and less, which reduces the efficiency of sizing. At the same time, due to the change of the position of carbon fiber relative to the liquid level of sizing liquid, the pressure on carbon fiber is different, which leads to a certain difference in the degree of sizing of the same batch of carbon fiber, which affects the overall quality of carbon fiber. Quality, another problem is to keep the sizing liquid in the sizing tank at the same level by continuously adding sizing liquid to the sizing tank, but it will be caused by the fusion of the sizing liquid in the sizing tank and the newly added sizing liquid The deviation affects the sizing quality of carbon fiber
