Description

TECHNICAL FIELD

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

[0002] The impregnated fibre twisting mechanism is a mechanism for twisting two or more impregnated yarns, such as the GFRP mesh production line disclosed in CN118269377A, which comprises an impregnated fibre twisting mechanism, i.e., a plurality of rotating drums are horizontally arranged on the 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 belt transmission, and at least two wire passing holes are axially arranged on the rotating drum.

[0003] In the working process, we found that the above-mentioned impregnated fibre 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 fibre is threaded, many of the fibre filaments will be glued, and the residual glue in the wire passing hole must be cleaned very cleanly before the yarn can be threaded again. SUMMARY

[0004] The utility model provides an impregnated fibre twisting mechanism to solve the technical problems, which can quickly clean the residual glue in the wire passing hole after pausing processing, so that the residual glue in the wire passing hole does not affect the threading of the subsequent yarn.

[0005] In order to solve the above technical problems, the utility model solves the problem by the following technical scheme: an impregnated fibre twisting mechanism, comprising a rotating drum driven by a driving device, the rotating drum is axially provided with at least two wire passing holes, and each wire passing hole is provided with a detachable protective sleeve with an axial through hole. When the impregnated fibre twisting mechanism is processing, the impregnated fibre is threaded in the protective sleeve, the glue will drop in the protective sleeve, when the processing needs to be paused, part of the yarn without glue can be threaded into the protective sleeve, then the yarn threading is paused, the protective sleeve is taken out of the wire passing hole, and the protective sleeve is disassembled or broken from both sides of the yarn, so that the protective sleeve can be cleaned or replaced, and when the yarn processing is replaced, the yarn can be directly cut, and the protective sleeve is taken out of the wire passing hole, thereby effectively avoiding the problem that the residual glue in the wire passing hole is difficult to clean and causes the subsequent yarn threading difficulty.

[0006] In the technical scheme, preferably, the protective sleeve is formed by combining a first split part and a second split part, and the first split part and the second split part are combined to form the axial through hole. The structure facilitates disassembly of the protective sleeve.

[0007] In the technical scheme, preferably, the first split part and the second split part have a connecting portion on the side surface, and a folding edge is arranged on the connecting portion, and the first split part and the second split part are combined to form the axial through hole by folding along the folding edge. The structure facilitates use of the protective sleeve, and the protective sleeve can be combined or disassembled by rotating along the folding edge.

[0008] In the technical scheme, preferably, the first split part is provided with two axial grooves, the second split part is provided with two axial protrusions, and when the first split part and the second split part are combined to form the axial through hole, the two axial protrusions are respectively clamped in the two axial grooves on the two sides of the axial through hole. The structure enables the first split part and the second split part to be positioned by clamping the protrusions in the axial grooves after being combined, and can prevent glue from overflowing from the gap between the first split part and the second split part.

[0009] In the technical scheme, preferably, the outer wall of the protective sleeve is provided with a positioning rib. The positioning rib can improve the strength of the protective sleeve and can achieve elastic support and positioning effect between the through hole.

[0010] In the technical scheme, preferably, the yarn support portion corresponding to the through hole is arranged on the yarn outlet side of the rotating drum, and the yarn support portion is provided with a through hole for the yarn to pass through. The structure enables the yarn to pass through the through hole without entering the pipe, thereby avoiding the influence of glue in the pipe on the yarn. The through hole is only used to support the yarn, and even if the support position is contaminated with glue, the support position is located on the outside and is easy to clean.

[0011] In the technical scheme, preferably, the yarn support portion is formed by bending a bending rod and fixing the bending rod on the rotating drum. The structure facilitates formation of the yarn support portion.

[0012] In the technical scheme, preferably, the yarn support portion is located on the radial outside of the rotating drum corresponding to the through hole.

[0013] Compared with the prior art, the impregnated fiber twisting mechanism has the following beneficial effects: during processing, the impregnated fiber is arranged in the protective sleeve, the glue can drip into the protective sleeve, when processing needs to be paused, the yarn that has not been impregnated can be continuously arranged in the protective sleeve, then the yarn arrangement is paused, the protective sleeve is taken out from the wire hole, the protective sleeve is disassembled or broken from both sides of the yarn, the protective sleeve can be cleaned or replaced, when the yarn is replaced, the yarn can be directly cut, the protective sleeve is taken out from the wire hole, and therefore the problem that the glue remaining in the wire hole is difficult to clean and causes difficulty in subsequent yarn arrangement is effectively avoided.

When the impregnated fiber twisting mechanism is processed, the impregnated fiber is arranged in the protective sleeve 4, the glue can drip into the protective sleeve 4, when processing needs to be paused, the yarn that has not been impregnated can be continuously arranged in the protective sleeve 4, then the yarn arrangement is paused, the protective sleeve 4 is taken out from the wire hole 2, the protective sleeve 4 is disassembled or broken from both sides of the yarn, the protective sleeve 4 can be cleaned or replaced, when the yarn is replaced, the yarn can be directly cut, the protective sleeve 4 is taken out from the wire hole 2, and therefore the problem that the glue remaining in the wire hole 2 is difficult to clean and causes difficulty in subsequent yarn arrangement is effectively avoided.

[0019] In the embodiment, the protective sleeve 4 is formed by splicing a first splicing part 5 and a second splicing part 6, and the axial through hole 3 is formed on the splicing surface of the first splicing part 5 and the second splicing part 6. The structure facilitates the disassembly of the protective sleeve 4.
