Description

Technical Field

[0001] The invention belongs to the technical field of textiles, and in particular relates to an additional device of a spinning frame and a method for spinning composite functional yarns using the additional device. Background Art

[0002] Composite functional yarn refers to yarn with special structure and appearance effect obtained by processing fibers or yarns with special raw materials or special equipment during the spinning and thread making process. Composite functional yarn is mainly used for decoration in the current market. There are many types of composite functional yarns, and their main value lies in their appearance. Composite functional yarns are currently mostly skin-core structures. There are few composite functional yarns for new spinning equipment on the market. Composite functional yarn technology for ring spinning machines is mostly to transform the spinning machine equipment itself, and there are no additional devices yet.

[0003] Patent CN111394852B proposes a method for preparing a functional two-color slub fancy yarn, which solves the problem of only one type of coated slub, that is, spinning two single-slub functional fancy yarns separately, and then twisting and heat-setting to form a two-color slub fancy yarn. The method and process described in the patent are cumbersome and complicated, and the two-color slub fancy yarn cannot be formed in one step.

[0004] Patent CN114269976A proposes a composite yarn, wherein the yarn is a fiber-based filament wound around a staple fiber core of the yarn or included in the core of the yarn and at least partially surrounded by a staple fiber sheath. The patent proposes that in one configuration, the staple fibers can form the core of the composite yarn, and conventional synthetic filaments can be wound around the core. In another configuration, conventional synthetic filaments can form the core of the composite yarn, and the staple fibers can form the sheath surrounding the core. The patent only proposes the types of fibers that can be spun into the composite yarn and the spinning process of the composite yarn, but does not propose a novel composite yarn spinning device.

[0005] Patent CN109972247A relates to a drafting transmission device for a ring spinning frame, which achieves the purpose of forming fancy yarn by changing the rotation speed of the front, middle and front rollers of the existing spinning frame through a PLC-controlled driving motor. However, this modification changes the normal spinning process and spinning technology of the existing spinning frame, causing inconvenience to production. Summary of the invention

[0006] In view of the deficiencies in the prior art, the object of the present invention is to provide an additional device for a spinning frame, which has a scientific and reasonable design and is easy to use.

[0007] The invention also provides a method for spinning composite functional yarn using the same, which is simple, feasible and suitable for large-scale production.

[0008] The additional device of the spinning frame described in the present invention includes the front roller, leather roller and yarn guide hook of the spinning frame, and also includes a motor controller. The motor controller drives the motor driver, and the motor driver controls the motor. The motor is connected to the driving wheel to control the rotation speed of the driving wheel. A connecting device is provided between the driving wheel and the driven plate, and a ball slide is provided under the driven plate. When the driving wheel rotates, the driven plate is driven to reciprocate along the ball slide through the connecting device. The driven plate is provided with a second filament guide hook, and the front roller of the spinning frame is provided at the end of the ball slide away from the driving wheel. A tension adjustment rod is provided obliquely above the end of the driving wheel away from the driven plate, and a first filament guide hook is provided on the tension adjustment rod away from the driving wheel. The motor controller-motor driver-motor constitutes a control system.

[0009] The direction in which the second filament guide hook reciprocates with the driven plate is in the same horizontal plane as the direction in which the yarn moves.

[0010] The device is linked with the spinning frame yarn guide hook lifting device to ensure that the second filament yarn guide hook always keeps a distance from the spinning frame yarn. It can guide the filament to be wound around the yarn without affecting the normal course of yarn production and at the same time does not change the speed difference between the driving wheel speed and the yarn.

[0011] The control system includes a stepper motor controller-a stepper motor driver-a stepper motor or a servo motor controller-a servo motor driver-a servo motor.

[0012] Preferably, the stepper motor controller is YF-19 type, and the controller is adjusted and controlled according to the type of functional yarn and the pattern effect of the composite functional yarn.

[0013] The servo controller, servo drive and servo motor have higher control accuracy and diversified programs, and can produce regular, irregular and other composite functional yarns with bamboo effects or other composite functional yarns.

[0014] Preferably, the servo motor model is ECMA-C10602RS, and the servo controller model is ASD-B2-0221-B with parameters; a fancy yarn control module CH-control ZD-001 is responsible for displaying fancy yarn programming; an encoder with a photoelectric sensor is responsible for autonomously detecting and matching the front roller speed, and constantly adjusting the servo motor speed so that the guide wire speed and the spinning spindle speed remain relatively balanced.

[0015] The second filament guide hooks are arranged on both sides of the driven plate.

[0016] Two fancy composite functional yarns with different colors or functions can be spun at the same time.

[0017] The connecting device comprises a connecting rod or a belt.

[0018] The moving range of the driven plate is selected according to the pattern effect of the required functional yarn review, the moving range of the connecting device being a connecting rod is 0-25mm, and the moving range of the connecting device being a belt is 0-120mm.

[0019] When the connecting device is a belt, a driven plate is fixed on the belt, and a driving wheel and a driven wheel are arranged at both ends of the belt.

[0020] The method of spinning composite functional yarn using the additional device of the spinning frame of the present invention is as follows: the yarn formed by spinning the spinning frame is led out from between the front roller and the leather roller, passes through the yarn guide hook and is wound on the spinning tube, the filament passes through the first filament guide hook, passes through the second filament guide hook on the driven plate through the tension adjustment rod, is introduced between the front roller and the yarn guide hook, and is wrapped around the yarn. The motor controller drives the motor driver, the motor driver controls the motor, the motor is connected to the driving wheel, controls the driving wheel to rotate, drives the driven plate on the connecting device to reciprocate, thereby driving the second filament guide hook to reciprocate, and the reciprocating motion of the second filament guide hook drives the filament and the yarn to produce a speed difference, forming a formed composite functional yarn. The filament wrapping can be accumulated to form bamboo knots, and the rest of the filaments are normally wrapped. The length of the bamboo knot depends on the stroke of the reciprocating motion of the driven plate and the speed difference between the second filament guide hook and the yarn.

[0021] The composite functional yarn can replace the filament and yarn varieties according to different functional requirements.

[0022] The driving wheel rotates at a speed of 0.1-999 rpm.

[0023] The delay time of the driving wheel rotation is 0-100s.

[0024] The reciprocating range of the driven plate is 0-120 mm.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] (1) The composite functional yarn obtained by the present invention can not only change different functional fibers to spin composite functional yarns, but also spin fancy yarns of different colors and types. Currently, the spinning technology is relatively mature, but the technology of fancy yarn types is relatively rare. The present invention provides a way of producing fancy composite functional yarns on existing spinning machines, avoiding the shortcomings of cumbersome fancy composite yarn processes and complicated operations.

[0027] (2) The device described in the present invention is simple and practical. The motor drives the driving wheel to rotate. The speed of the driving wheel controls the reciprocating speed of the driven plate, so that the filaments are wrapped around the spun yarn to produce different effects, thereby accelerating the production efficiency of fancy yarns and improving the spinning technology of composite functional yarns.

[0028] (3) The control system of the device of the present invention uses a servo controller, a servo driver, and a servo motor, which has higher control accuracy and diversified programs, and can produce regular and irregular fancy yarns. At the same time, as an additional device of the existing spinning frame, the device does not affect the normal production of yarn and does not need to modify the structure of the spinning frame.
