Description

Technical Field

[0001] The present invention relates to the technical field of fiber laying machines, in particular to a constant tension fiber feeding and withdrawing device for aerospace and a carbon fiber fiber laying machine thereof. Background Art

[0002] As we all know, carbon fiber composite materials are generally composed of carbon fiber and resin, and have the characteristics of high strength, high modulus, wear resistance, heat resistance, and corrosion resistance. In addition, in the field of aerospace material production, the quality of traditional manual laying methods depends on factors such as personnel ability and quality and whether the operation is standardized. The product quality fluctuates greatly and the scrap rate is high. Automatic laying has high control accuracy, good repeatability and consistency of product quality, and is an important means to achieve high-performance digital manufacturing of composite materials.

[0003] When using existing carbon fiber laying machines, pressure rollers are required to make the laying effect more uniform. However, long-term contact between the pressure rollers and the material will cause certain wear. Since the pressure rollers do not have the function of being easily replaced on the carbon fiber laying machines, and the existing laying machines also lack a structural setting for tensioning during the feeding and withdrawing process, the use function of the laying machines needs to be improved.

[0004] The above information disclosed in the Background section is only for enhancement of understanding of the background of the present disclosure and therefore it may include information that does not constitute the prior art that is already known to one of ordinary skill in the art. Summary of the invention

When the second cylinder drives the push plate to move upward, the two plate bodies can lose the force on the plug block, thereby facilitating the disassembly and assembly of the pressure roller on the carbon fiber laying machine body.

[0016] Preferably, the number of the connecting plates is two, and slots are provided on adjacent sides of the two connecting plates, and the insert blocks are inserted into the slots.
