[0002] In the modern textile industry field, false twist unit is a kind of extremely key device. It is mainly applied to the production and processing of chemical fiber filament, changes the structure and performance of yarn by exerting false twist on yarn, endows yarn with many excellent properties such as increasing elasticity, improving hand feeling and improving the loftiness of fabric, thereby greatly improving the quality and market competitiveness of final textile products. For this reason, the performance and working mode of false twist unit are quite remarkable for the influence of the whole chemical fiber textile production link.

[0003] At present, the common false twist unit on the market has certain deficiency in driving mode. The traditional false twist unit mostly adopts centralized driving mode, that is, one or a few motors are used to drive multiple false twist units to rotate simultaneously by transmission mechanism (such as belt transmission, gear transmission, etc.).

[0004] With the continuous development of textile process towards fine and diversification, the requirement for accurate control of false twist unit is also increasing. Ideally, if each false twist unit can be driven by independent motor, then more accurate twist adjustment, speed control and other operations of each false twist point can be realized. However, in actual design and application, there is a prominent problem. The existing false twist unit usually needs to be integrated in the limited space of textile production equipment, and its internal structure is compact, so it is difficult to set independent motor in each false twist unit for driving.

DETAILED DESCRIPTION

[0025] In view of the fact that the existing textile equipment cannot set up a separate driving mechanism in each false twist unit due to its own size limitation, the present application provides a false twist unit with different structure to solve the above problems. In its structure, a driving shaft mechanism and a driven shaft mechanism are used to drive the rotation of the false twist disc, wherein the driving shaft mechanism comprises a servo motor, the servo motor has an encoder, a magnetic head, a stator and an output shaft, the output shaft has a first false twist disc mounting part, a first transmission part and a rotor part along the axial direction, the rotor part is provided with a permanent magnet in the circumferential direction, the magnetic head is embedded in the rear end of the output shaft, the driven shaft mechanism comprises a driven shaft, the driven shaft has a second false twist disc mounting part and a second transmission part along the axial direction, the first transmission part and the second transmission part are arranged in transmission, and the output shaft drives the rotation of the driven shaft through the transmission when rotating.

[0026] In the above structure, the first false twist disc mounting part, the first transmission part and the rotor part are directly formed by the output shaft of the servo motor, and the magnetic head is embedded in the rear end of the output shaft. Compared with the structure in which the servo motor drives the separate false twist disc mounting structure and transmission structure, this arrangement obviously reduces the size. In addition, the driven shaft mechanism can also be rotated through the transmission cooperation of the first transmission part and the second transmission part. Thus, the driving shaft and the driven shaft drive the rotation of the false twist disc together, realizing the false twist function of the false twist unit.

[0027] The method for manufacturing the above output shaft is known. First, the length of the output shaft should be long enough to have sufficient length in the axial direction for forming the first false twist disc mounting part, the first transmission part and the rotor part, and for mounting the magnetic head, and the radius of the output shaft should match the inner diameter of the false twist disc. The first false twist disc mounting part can be a rod body, i.e. directly formed by a part of the output shaft, and the length of the first false twist disc mounting part can meet the requirement of fixing one to several false twist discs along the axial direction, which can be estimated according to the number, thickness and interval of the false twist discs. The false twist disc can be fixed on the first false twist disc mounting part by known fixing methods, so as to rotate together with the output shaft. The first transmission part can integrally have a transmission structure, or another transmission member can be provided, and the length of the first transmission part can be estimated according to the length of the transmission structure or the transmission member. The transmission structure or the transmission member includes but is not limited to gear transmission and belt transmission.

[0028] The method of manufacturing the driven shaft is known. The length of the driven shaft should be long enough to have sufficient length in the axial direction to form the second false twist disc mounting portion and the second transmission portion, and the radius of the driven shaft should match the inner diameter of the false twist disc. The second false twist disc mounting portion can be a rod body, i.e. directly formed by a part of the driven shaft, and the length of the second false twist disc mounting portion can satisfy the fixation of one or more false twist discs in the axial direction, which can be estimated according to the number, thickness and interval of the false twist discs. The false twist disc can be fixed on the second false twist disc mounting portion by a known fixation manner, so as to rotate together with the driven shaft. The second transmission portion can integrally have a transmission structure, or a transmission member can be additionally arranged. The transmission structure or the transmission member includes, but is not limited to, a gear transmission, a belt transmission.

[0029] In one implementation of the transmission cooperation between the first transmission portion and the second transmission portion, the transmission cooperation is realized by a transmission mechanism. In one specific structure, the transmission mechanism includes: a driving pulley arranged on the first transmission portion to rotate together with the output shaft; a driven pulley arranged on the second transmission portion to rotate together with the driven shaft; and a belt jointly sleeved on the driving pulley and the driven pulley to drive the driven pulley to rotate together with the driving pulley. Further, the belt and the driving pulley and the driven pulley have meshing tooth structures to prevent the belt from slipping.

[0030] The principle of the rotation of the driving output shaft of the servo motor is known. In the operation of the servo motor, the rotor part of the output shaft is driven to rotate by the magnetic force of the stator to drive the whole output shaft to rotate.

[0031] The encoder and the magnetic head in the servo motor are used to detect information such as rotation speed and rotation angle in real time, and can feed back these data to the driver or the control system to realize the synchronous control of the rotation speed of the servo motor.

[0032] The false twist unit further includes a seat body, and the output shaft and the driven shaft are rotatably arranged on the seat body. A plurality of assembly holes corresponding to the number of the output shaft and the driven shaft are arranged through the seat body, the output shaft and the driven shaft pass through the assembly holes on the seat body, and bearings are arranged between the output shaft, the driven shaft and the assembly holes. In one specific implementable structure, the first and second false twist disc mounting portions on the output shaft and the driven shaft are located in front of the seat body, and the first and second transmission portions are located in the rear of the seat body.

[0033] The false twist unit can be used in a false twister and various textile equipment related to false twisting, such as a texturing machine. When a plurality of false twist units are contained, the servo motors in the false twist units can be controlled in speed synchronization by a control system or a controller.
