Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of impregnated fiber processing equipment, and specifically is an impregnated fiber twisting mechanism. BACKGROUND

[0002] The impregnated fiber twisting mechanism is a mechanism for twisting two or more impregnated yarns into a strand. As disclosed in CN118269377A, a GFRP mesh production line includes an impregnated fiber twisting mechanism, i.e., a plurality of rotating drums are horizontally arranged on a rack, a plurality of transmission wheels are arranged on the rotating drums, a first servo motor is arranged on the rack, the first servo motor is connected to the plurality of transmission wheels through a belt drive, and at least two wire passing holes are axially arranged on the rotating drum. In operation, each impregnated yarn passes through a wire passing hole connected to a traction mechanism, and the reciprocating rotation of the transmission wheel driven by the first servo motor realizes the twisting operation of the impregnated yarns.

[0003] In the working process, we found that the above-mentioned impregnated fiber twisting mechanism has no problem in initial processing, but when the work is paused or different models of products need to be processed, we found that the residual glue in the wire passing hole affects the threading of the yarn, especially when the glass fiber is threaded, many of the fiber filaments will be glued, and the residual glue in the wire passing hole must be cleaned very cleanly before the yarn can be re-threaded. Since the impregnated fiber twisting mechanism contains many such rotating drums, it takes a lot of time and labor to clean the glue in the wire passing hole, and since the impregnated fiber twisting mechanism has multiple wire passing holes on each rotating drum, it further increases the workload of cleaning the glue, and in order to guide and spread the yarn in each wire passing hole, a wire guide tube is also arranged on the yarn outlet side of the rotating drum, which results in a bent wire guide tube that needs to be cleaned, further increasing the difficulty of cleaning the glue. SUMMARY

[0009] In the above technical scheme, preferably, the protective sleeve is formed by combining the first split piece and the second split piece, and the axial through hole is formed on the combined surface of the first split piece and the second split piece.Using this structure facilitates the disassembly of the protective sleeve.

[0010] In the above technical scheme, preferably, one side surface of the first split piece and the second split piece has a connecting portion, and a folded edge is arranged on the connecting portion.The first split piece and the second split piece are combined to form the axial through hole by folding along the folded edge.Using this structure facilitates the use of the protective sleeve, and the protective sleeve can be combined or separated by rotating along the folded edge.
