TECHNICAL FIELD

[0001] The present application relates to the technical field of textile machinery, in particular to a weft insertion device of a carbon fiber cloth loom. BACKGROUND

[0002] With the breakthrough of the key technology of large tow carbon fiber in China, the application of carbon fiber will be more popular in the future, and the application of industrial composite materials will also experience explosive development. As a supplier of composite material equipment and a manufacturer of multi-layer cloth looms, our company also keeps pace with the market and continuously develops special composite material equipment and special rapier looms to meet the needs of customers. Among them, carbon fiber multi-layer cloth and three-dimensional structure cloth are widely used materials in the future. The manufacturing equipment is the key equipment. The material used for producing carbon fiber cloth is a carbon fiber unidirectional prepreg tape with a thickness of about 0.2mm and a width of 20mm. This brings many problems. On the one hand, in the storage of weft, the existing technology generally adopts a swing structure to prevent the retraction of the carbon fiber unidirectional prepreg tape, but such a structure is very complex, has poor stability during operation, is easy to wear and tear, and has a short service life. On the other hand, the thickness of the carbon fiber unidirectional prepreg tape is about 0.2mm, which has high requirements for the weft insertion mechanism. The existing weft insertion mechanism cannot stably clamp the carbon fiber unidirectional prepreg tape. Moreover, as one of the core components of the entire loom, the weft insertion mechanism needs to be adjusted when it fails, which greatly affects the efficiency of the entire loom. SUMMARY

[0007] In the technical scheme, the shell is cylindrical, and the ball body is in transition fit with the inner wall of the shell.

[0008] In the technical scheme, the valve is closed when the air suction fan is working.

[0009] In the technical scheme, the connecting piece comprises a connecting plate and a connecting rod, two ends of the connecting plate are connected with the traction rope and the connecting rod respectively, the upper part of the connecting rod is provided with a stop block, and the lower part is fixedly connected with a reset spring.
