Description

A Roller Cutter Wheel Hybrid Ramie Traction Cutting Spinning Equipment

technical field

The invention relates to the field of textile engineering, in particular to a roller-cutter-wheel hybrid ramie stretch-cutting spinning device.

Background technique

The existing ramie spinning processing flow is: refined hemp→soft hemp process→opening process→pre-merging process (2 steps)→combing process→pinning process (3-4 steps)→roving process→spinning process.

In the existing ramie spinning process, the soft hemp process is mainly to loosen and soften the dry hemp by kneading, and the opening process is mainly to break some super-long fibers, and to initially loosen the dry hemp The combing process is mainly to further carefully comb the fibers after opening into single fibers; the pre-combing process is mainly to improve the straightening and parallelism of the fibers in the carding sliver and the uniformity of the sliver, and the combing process is mainly to eliminate Fibers whose length is shorter than a certain level can improve the uniformity of fiber length; the needle carding process mainly improves the uniformity and mixing degree of fibers through merging and drafting; sliver) for preliminary drafting and twisting to reduce the drafting burden of the spinning process; the spinning process is to further draft and twist the roving to form the final ramie yarn product.

In the existing ramie spinning process, because the two kinds of equipment adopted in the opening process and the carding process mainly use its sawtooth and other parts to strongly comb the ramie fibers, causing damage and entanglement of the ramie fibers, resulting in ramie fibers The short staples in the fiber increase, and the hemp grains increase sharply, but the problems of ultra-long fibers and uneven fiber lengths in ramie itself are still not well resolved, and in many spinning processes, in order to achieve reduction The purpose of doubling yarns is usually splitting and carding with needle boards, but this kind of splitting and carding cannot achieve the desired effect, and the ramie fibers are easily entangled on the needle boards during the carding process, thereby disabling the needle boards. Pull off, so that the product quality of ramie can not be guaranteed.

At present, the roller stretching machine is divided into needle row type and needle roller type. The needle row type roller stretching machine is mainly used in the field of wool spinning. , because the fibers in the fine-dried hemp strips are not neatly arranged and the fibers are seriously entangled, it is very difficult to pull the hemp strips through the needle row by hand. It must be fully sorted by hand before the hemp strips are pulled through the needle row to make them loose after the initial Needle rows can only pass through the needle row, so the machine is prone to congestion when it is running, resulting in abnormal production; the needle-roller roller stretching machine, that is, a number of needle rows are implanted on a rotating roller, and the device is collectively called a needle roller. Due to the long fiber length, chaotic fiber arrangement and entanglement of fibers in the fed fine-dried hemp, and the hemp sliver contains more hard strips and clusters, the phenomenon of fiber winding around the needle roll occurs during the operation. One is to make the needle teeth bend and deform or even break the needle, and the other is that the continuity of the start-up cannot be guaranteed, and the machine has to be shut down frequently to clean up the winding fibers, which brings difficulties to normal continuous production.

The adjustment range of the up and down stroke of the adjustable stroke cylinder 19 is 0-40mm. When adjusting, care should be taken that the cutter wheel 10 cannot touch it. To the roller device 14. When the fiber is transported to the position of the cutter wheel 10, the fiber layer is fully gripped and engaged by the cutter wheel 10 and the roller device 14, and is subject to certain straightening and splitting effects in the longitudinal direction. In order to weaken the lateral connection between the sliver and further increase the looseness of the sliver before pulling and cutting, a function of lateral vibration is added to the cutter wheel while the cutter wheel 10 is splitting, that is, a drive shaft of the cutter wheel 10 is connected with a The eccentric wheel device 7 is used to make the cutter wheel 10 move laterally. Because the cutter wheel 10 acts on the lateral vibration simultaneously, the fiber layer is also subjected to the lateral vibration and loosening effect simultaneously. The eccentric wheel device 7 is embedded on the vibrating base and driven by the second motor 21, and the vibrating base is connected with the base 18 and the second motor 21 through a pair of soft damping springs. When the button is turned on to make the second motor 21 work, the eccentric wheel device 7 drives the vibrating seat to generate lateral movement in the horizontal direction, thereby driving the cutter wheel 10 to generate lateral vibration at the same time when rotating, so that the fiber bundle generates a lateral motion in contact with the cutter wheel 10 Shake to loosen the hemp strips as much as possible, so that the splitting effect of the cutter wheel 10 is more effective, so as to reduce the hard strips. After splitting and lateral shaking by the cutter wheel 10, part of the hard strips and clusters in the hemp strips have been loosened, which reduces the hard strips and clusters; The fibers are split and fluffed by the knife wheel 10, and the breaking efficiency is improved during stretch cutting, which reduces the long fiber rate and length unevenness in the final stretch cut strips, and further reduces hard strips and bundles, improving the quality of stretch cut strips. get improved.
