Tow conveying device for composite material tow laying equipment

Abstract

The invention belongs to the technical field of tow laying equipment, and particularly relates to a tow conveying device for composite material tow laying equipment. The tow conveying device comprises a tow inlet assembly, a conveying pipeline and a tow outlet assembly. The conveying pipeline comprises a spring piece, a sheath and a tow tube; the tow inlet assembly and the tow outlet assembly are connected through a tow pipe. The two spring pieces are symmetrically arranged on the two sides of the tow tube. According to the tow conveying device, the low-resistance pipeline is utilized, and friction loss between tows and the pipeline in the tow conveying process is reduced; the conveying channel of the tows is provided with a fixing and protecting device of a corresponding pipeline, so that the tows can be smoothly conveyed when the conveying channel is twisted and bent, and meanwhile, the tow pipe can be prevented from being damaged when the tow pipe is twisted, bent and the like.

Description

technical field [0001] The invention belongs to the technical field of tow laying equipment, and in particular relates to a tow conveying device for composite material tow laying equipment. Background technique [0002] The main functional parts of the composite material tow laying equipment to realize the tow laying are the laying head and creel. During the working process of the composite material tow laying equipment, each composite material tow needs to be independently entered into the laying head from the creel through the corresponding guide mechanism to complete the laying of the tow. In current tow laying equipment at home and abroad, the form of mutual correspondence between the creel and the yarn laying head is the integrated form of the silk laying head and the creel, and the form of separation of the silk laying head and the creel. In the two structural forms, the guiding mechanism between the creel and the laying head usually adopts a pulley block to realize t...

AI Technical Summary

Problems solved by technology

Although the factory environment is required to ensure constant temperature, constant humidity and dust-free during the process of laying the tow, due to the influence of other uncertain environmental factors such as personnel flow, the quality of the tow will often decrease during the transmission process

[0004] Compared with the equipment in which the creel and the laying head are separated, the tow laying equipment needs a longer conveying distance. If the form of a pulley block is used, it will be more affected by the above conditions. Large; the transportation in the form of multi-section pipelines connected by pipelines and joint mechanisms often causes wear and tear between the tow and the pipeline, bending, twisting of the pipeline, and temperature changes in the pipeline will all affect the tow, resulting in poor use of the tow
