Description
Technical Field
The utility model relates to a ramie weaving equipment technical field, in particular to draft gauge adjustable drafting arrangement and ramie spinning frame thereof.
Background
The flax spinning process is determined by the characteristics of flax fibers, and the flax fibers have unique forms, chemical compositions and organizational structures different from cotton fibers, so the spinning process is different from the cotton fibers. Flax fiber is coarse and hard, fiber length is long, and fiber are bonded with each other, so that the flax spinning is always carried out by a wet spinning ring spinning frame. The wet spinning ring spinning frame can basically meet the spinning requirements of flax, yarns with higher strength, higher yarn count and more uniform yarn levelness can be spun, and the yarns can basically meet the requirements of clothing and decoration of flax textiles. However, with the improvement of the living standard of people, the requirements on the quality of textiles for linen clothing and decoration are higher and higher, the product quality of the existing wet spinning ring spinning frame cannot meet the requirements, and the improvement of the wet spinning ring spinning frame is an urgent matter.
In the spinning frame, the most critical part is the drafting device. The drafting mechanism has the function that after the roving enters the drafting zone, the process fiber is further split and thinned due to the different surface linear speeds of the front drafting roller and the rear drafting roller, slippage is generated among the fibers, the sliver is lengthened and thinned, and the sliver becomes spun yarn through twisting. The improvement of the quality of the finished yarn, the production and the draft ratio requires continuous improvement and modification of the drafting device. The improvement of the drafting device can improve the yarn quality, reduce the raw material cost of the flax and the labor cost of workers, and reduce the configuration of a machine table.
The flax has different varieties and different growth environments, the different primary processing technologies lead to great difference in the fiber length of the flax scutching process, the average length is 17-26mm, the longest length can reach 200mm, the wet spinning length of the roving process fiber for spinning is 200-300mm, and the fiber length of the roving process fiber after boiling and bleaching is 100-150 mm. The distance between the front jaw and the rear jaw of the existing drafting mechanism is about 140mm, and the length cannot adapt to the longer fiber length of the flax process, so that long fibers are easily broken in the spinning process, or the long fibers cannot be drafted at all, and roving is caused. Sudden fiber breakage can result in a change in speed and can easily rub against adjacent fibers to create neps. And the sudden breaking of the fiber can cause the tension to change instantly, and when the change is overlarge, the broken end can be caused, the yarn quality is influenced, and the spinning process can not be smoothly carried out. "running rovings" can lead to even more serious quality problems.
The front and rear roller pairs of the existing drafting mechanism are used for holding the fiber by an upper roller and a lower roller. However, the flax fiber is coarse and hard, is not single fiber, is a craft fiber with several fibers bonded together, and is easy to have insufficient holding force when only using an upper roller and a lower roller to hold the fiber. When the holding force is insufficient, the roving is insufficiently drawn to form slubby, so that the finished yarn is poor in evenness.
Patent CN 207362394U discloses a gauge length regulator suitable for ramie and cotton spun yarn process blending, including the pressure bar, adjusts the pole dead lever, adjusts including spout and fixing device on the pole dead lever, adjusts the pole dead lever and is together fixed with the pressure bar, adjusts the pole and passes through fixing device to be fixed in the spout.
The above patent is suitable for a gauge length regulator for ramie and cotton spinning process blending, and during conventional spinning, an adjusting rod and an adjusting rod fixing rod part can be omitted, so that normal use of a rear area pressure rod is not influenced. When the ramie and the cotton are co-spun in the spinning link, the spinning space of the ramie can be adjusted by the space adjuster, so that the ramie fibers cannot be broken, the cotton roving strips are normally drafted, and the ramie and the cotton are co-spun on cotton spinning equipment.
