Description

Technical Field

[0001] The utility model relates to an arbitrary spindle disk type false twist device, which has the characteristics of independent drive and multi-yarn path yarn compounding, and is applicable to textile enterprises and scientific research institutions for developing new composite false twist devices and fancy yarns with multiple twist degrees twisted together at one time. Background Art

[0002] In the 1930s, people began to produce knot yarns with hand-operated doubling machines; in the 1950s, colored spun yarns and fancy yarns came out; after the 1970s, the hollow spindle technology and equipment promoted the technological transformation of fancy twisting machines and the diversification of fancy yarn varieties. Fancy yarns are decorative yarns produced from special fiber raw materials or by unconventional processing methods, with special structures and appearance effects, such as color-gradual yarns, segment-colored yarns, position-coated slub yarns, new joint yarns, new friction spinning yarns, intelligent yarns, etc.

[0003] In order to develop yarns with a soft handfeel, engineers use softeners to soften the yarns or use false twist devices to reduce the yarn twist. Reducing the yarn twist is the best method to permanently improve the softness of fabrics. The current mainstream false twist method is the low-torque spinning technology. This technology uses a false twist device to change the yarn structure, thereby reducing the residual torque of the yarn.

[0004] At present, most false twist devices are positive dynamic false twist devices, mainly including double-dragon belt false twist devices, multi-axis friction disk false twist devices, cross rubber ring type false twist devices, rotary center type false twist devices, and air flow type false twist devices. In production and processing, the technology of the rotary center type false twist device is mature and industrialized, and its false twist device belongs to a single spindle and single yarn path. The guide yarn wheel of this false twist device has a small size, and the length of the false twist yarn segment is short. It has a better effect when spinning yarns of cotton-type fibers, and the yarn structure is mostly siro yarn.

[0005] In order to develop high-quality fancy yarns, developing long-range false twist and multi-yarn path compounding is a new technical method. Therefore, it is of great value to research and develop a new disk spindle type false twist spinning device, which can be used in the operation of medium-length and multi-twist compound yarns.

[0006] This application proposes an arbitrary spindle disk type false twist device with a simple structure and good use effect. Summary of the Invention

[0007] The purpose of the utility model is realized through the following technical solutions:

[0008] The guide yarn wheel assembly consists of a guide yarn wheel, a spindle group bottom plate, a gear group shaft system, a resin cover, a fixed retaining ring, a guide yarn porcelain ring, etc.; the fixed retaining ring is connected to the support plate or the resin cover, and forms a closed box body with the bottom plate and the resin cover to constrain the shaft system of the transmission gear. The outer extension shaft end of the micro motor is fixedly equipped with a resin gear, a shaft sleeve, and a bearing, and the guide yarn wheel is driven through the gear group.

[0009] When the arbitrary spindle false-twist device is in use, it consists of 3 to 12 false-twist devices and a controller. According to the requirements of the machine or the number of spindles of the test roving prototype, multiple groups of spindle false-twist devices are set, and the operating conditions of some spindles can also be randomly selected. The arbitrary spindle false-twist device is fixedly installed on the upper edge of the yarn guide hook position of the roving frame. In order to achieve multi-channel yarn compound twisting, the installation of this device does not replace the original yarn guide hook.

[0010] Working principle of the arbitrary spindle false-twist device: The controller of this device controls most of the spindle false-twisters. Each spindle false-twister is fixedly installed at the upper end position of the original yarn guide leaf plate at each spindle position of the roving frame. Each spindle false-twister is equipped with a micro motor. A resin gear is fixedly installed on the outer extension shaft of the micro motor, and the transmission is achieved through a set of gear transmissions. The output end of the gear group is connected to the yarn guide wheel to achieve yarn guiding and false-twisting or twisting. This false-twister can guide 1 to 3 strands of yarn to be compounded into yarn, and can produce types of yarn such as low-twist single yarn, low-twist and high-twist compound yarn, and the compound of low-twist or high-twist yarn and untwisted yarn.

[0011] The utility model has the following characteristics compared with the prior art:

[0012] Compared with the conventional single-spindle false-twist device, the arbitrary spindle false-twist device can increase the outer extension shaft of the yarn guide wheel to realize the replacement of different specifications of yarn guide disks and achieve false-twist spinning of different types of yarn. Each spindle false-twister of this device operates independently, and can also achieve multi-channel compounding. The number of disks can be selected according to the test spinning material to adjust the length of the false-twist yarn path, and different false-twist amounts can also be adjusted for different spindle positions by controlling the drive frequency for each spindle. This device is especially suitable for engineering and technical personnel in new spinning processing enterprises and textile research institutes to develop and trial-produce high-quality new fancy yarns.
