The rapier loom is a type of shuttleless loom widely made use of at present. Its active weft insertion technique has good variety adaptability, can adapt to the weft insertion of different yarns, and has evident advantages in multi-color weft weaving. In the process of manufacturing and also making use of rapier looms, some firms discovered that some layouts of theloom were not acceptable, so they improved the equipment.
In production, some rapier looms have imperfections in the selvedge guide frame, and the capability of the bundle yarn that can be made use of on the overview structure is tiny, as well as frequent thread adjustments are needed. In order to fix the above issues, we eliminated all the skein yarn guides on both sides, as well as changed the existing waste-side thread feeder assistance feet on the square tube light beam into support feet that can be mounted on both sides of the thread feeder. The waste side yarn feeding drum is set up outside, and the selvedge thread feeding drum is installed on the inside. The certain improvement approaches as well as steps are as adheres to.
Initial procedure a little shaft similar to the mandrel of the waste thread feeding bobbin, as well as connect it to the other end of the loom Use the thrown out warp bars to make an easy hanging foot for installing the bobbin brake band assembly, as well as fix the easy hanging foot and also the waste side thread feeding bobbin foot with M6 × 20 mm countersunk screws. After that, utilize the scrap side thread feeding bobbin, mount them on the mandrel inside the hanging legs, and use the bobbin brake band to adjust and regulate the tension of the selvedge string. Ultimately, the ground airplane of the square tube beam of light supporting foot at the rear of the equipment is encountering upwards, and also the square tube is set up on it, to ensure that the whole twisted side as well as waste side yarn feeding supporting foot will certainly be raised by almost 15 cm, which will make it more convenient to obstruct the machine and operate after the equipment.
After the transformation, the selvedge plan has a huge yarn capability, and also it can be made use of for majority a year after substitute. After getting rid of the initial selvedge guide frame, not only the cleaning job is simple, however the selvage yarn breaks and also the troubles such as the lock not being secured are well managed. This change can conserve the business concerning 150 yuan in handling charges for small-tube yarns per year.
When clients utilize some rapier looms to generate tiny canvas, they find that the scrap edges of scissors can not meet the needs of use. The primary symptoms: the toughness of the scissors brace is insufficient, as well as the resonance is noticeable throughout usage; the scissors blades are not resilient as well as call for constant sharpening and even replacement; There is an issue of poor splitting up of waste edges and also torn edges of the textile. After on-site observation, research and also analysis, we have actually taken on the adhering to enhancement measures.
First enhance the scissors web cam. The scissor camera is improved from two elements: the profile curve of the scissor camera as well as the material. The original movable scissor blade transmission component is an eccentric web cam, and also weft insertion and also reducing are performed once. In order to boost the shearing effect, the protruding contour curve is boosted right into a figure of eight. The enhanced scissor webcam understands weft insertion as well as reducing two times at once, and the cutting regularity is doubled, which is beneficial to the cutting of waste edges of hefty materials. The original scissors web cam is shot formed of glass fiber reinforced nylon, which appropriates for mass production. In order to enhance the wear resistance and also help with the production of one item, the material of the scissors webcam is transformed to 45 steel for warm therapy, which enhances the wear resistance. The second is to change the product grade of the scissors blade. The original scissors blade is YG8 difficult alloy, which has high toughness, impact resistance, but reduced wear resistance. In order to improve the wear resistance, combined with the working conditions of the scissors, the blade product is altered to YG6 sealed carbide. Again, strengthen the fixed blade holder. In order to boost the strength of the taken care of blade owner, the density of the dealt with blade owner was altered from 4 mm to 5 mm. Via the above renovations, the efficiency of reducing waste sides is significantly boosted, as well as the efficiency of starting theloom is significantly improved, which satisfies the needs of customers for weaving usage.
The version of loom machine made use of by Suntech is ST collection. The staff discovered the complying with deficiencies in the waste edge thread gadget of the rapier loom throughout production: the stress of each waste edge yarn on the loom can not be adjusted separately; the stress of the waste side thread is various, leading to poor side flatness as well as poor creating; the loom When generating to the middle shaft as well as the small shaft, the cumulative tension distinction is outstanding, and also the private slack scrap edge yarn causes the warp droplets to sink, causing unreasonable stoppage.
In reaction to the above issues, the business's technical personnel made the adhering to enhancements: Firstly, cancel the waste edge thread winding tools. Eliminating the weaving of the waste yarn tray can conserve labor. Secondly, get rid of the initial devices selvedge thread seat, make and also install waste selvedge thread as well as selvedge thread creel with washer springtime tensioner, with a capability of 10 bobbins. Both waste side thread and skeined thread straight use pagoda bobbin, as well as go through the decrease warp and also heald after being changed by the tensioner. The amount as well as thread number of waste side thread and also skein yarn can be flexibly transformed as well as changed according to the variety. The stress of single waste yarn and skein yarn can be flexibly readjusted at any time.
After the above enhancements, it not only saves manpower as well as product resources, enhances the versatility of waste side yarn and skein yarn products, but likewise raises the efficiency of the loom from 73% before the adjustment to 87% after the change, and the selvedge top quality has actually additionally been dramatically enhanced.
