Description

Portable spinning quality on-line measuring device

Technical Field

The utility model relates to the field of spinning detection equipment, in particular to a portable spinning quality online detection device.

Background

The ring spinning frame is a spinning frame which is twisted and wound by a spindle, a ring and a bead ring, and comprises various ring spinning frames such as cotton spinning, wool spinning, silk spinning, hemp spinning and the like, and the hemp spinning (ramie and flax) ring spinning frame comprises long hemp spinning and short hemp spinning. Generally consists of feeding, drafting, twisting and winding mechanisms and the like. The ring spinning frame is divided into a roving unwinding zone, a back drafting zone, a spinning zone, a balloon zone and a winding zone. The roving is fed to a drafting mechanism consisting of pairs of rollers (rear roller 7, middle roller 8 and front roller 9) via a guide bar driven by a traversing device, typically double apron drafting. The roller gauge and the leather collar frame length can be adjusted according to the fiber length; the upper apron pin is a spring swing pin, the lower apron pin is a long curved pin, and the jaw gauge of the upper pin and the lower pin is positioned by a gauge block. Specifically, the total draft capacity of the double apron draft mechanism is about 50 times. The front roller 9 outputs sliver, which passes through the wire ring straddling the ring via the yarn guide hook 6 and winds around the bobbin rotating together with the spindle. The tension of the wound yarn drags the bead ring to revolve along the ring, twisting the sliver, called ring twisting. The difference in spindle and bead speeds causes the sliver to be wound around the bobbin. The forming mechanism makes the ring plate move up and down regularly to complete the short-stroke conical winding of the spun yarn. The speed of the bead ring varies with the winding diameter, so that the dynamic twist of the sliver varies, but can be compensated for during unwinding. The bead ring has a twisting blocking function on twist transmission, so that the twist of the balloon segment is increased. The yarn guide hook 6 has a twist-trapping phenomenon, so that the twist of the spinning section is reduced. Specifically, the yarn length between the bead ring and the winding point (sticking point) on the bobbin is the maximum and constant twist, and this yarn length is called a spun yarn, and the bobbin and the spun yarn are collectively called a cop.

In the spinning process, the length, diameter, sectional area, morphology and the like of the cotton fiber are uncertain. The input raw material of the spinning frame is semi-finished roving, and the raw material is from ginned cotton to roving, and the purposes of straightening, straightening and eliminating front and back hooks of all cotton fibers cannot be achieved even though more than ten working procedures are carried out. The cross section of the cotton fiber is in a waist round shape, the cross sections are different, the number of the fiber at two positions is the same for the roving, but the total cross sections are not necessarily the same, and the phenomenon of uncertainty of the input raw materials of the ring spinning frame is the phenomenon.

At present, in the process of producing cop, if a certain spindle position in cop production equipment or a certain mechanism related to the spindle position fails, the spinning quality of the spindle spun yarn is problematic, and in order to improve the quality of spun yarn and cop production, quality detection is required for all produced cop. The conventional method is to take spun cop as a detection object, obtain the weight of the cop by intercepting a certain sample and a weight measuring device, judge whether the weight of the obtained cop is in a preset range, and finally determine whether the quality of the cop is qualified according to a judging result. The quality detection operation is located after doffing, and a re-spinning operation is required to be carried out on the spun cop or the cop is treated as a defective product, so that waste is caused; in addition, the method of judging the quality by weight is greatly affected by environmental factors, for example, the air humidity increases the weight of spun yarn, thereby causing deviation of detection data.
