Description

Technical Field

[0001] The utility model relates to a twisting and covering mechanism for fancy colored core-spun yarns with a gradient color effect. Background Art

[0002] Yarn is the main raw material for weaving clothing. The style of yarn plays a great role in the effect of clothing, especially for sweaters.

[0003] The color of yarn is a way to reflect its style. At present, conventional yarns are mostly single-color or blended with multiple colors. Single-color yarns are monotonous in color and are usually used for formal wear. Multi-color fancy yarns are lively and vibrant in color and are usually used for casual wear. At present, fancy yarns are usually blended from fibers of different colors or spray-dyed multiple times. The colors of blended yarns look messy, while the coloring power of spray-dyed fancy yarns is poor and easy to fade.

[0004] Yarns with gradient color effects can give people a neat, refined and vibrant style when made into clothing. They are not only suitable for casual wear but also for formal wear. Therefore, they have good market prospects. However, yarns with gradient color effects are currently difficult to achieve mass production. Utility Model Content

DETAILED DESCRIPTION

[0018] The specific implementation scheme of the utility model is described in detail below in conjunction with the accompanying drawings.

[0020] The core wire unwinding and twisting mechanism comprises a base 1, on which a first clamping seat 3 for clamping a core wire bobbin 2 is arranged, the first clamping seat 3 is rotatably connected to the base 1 via a rotating shaft 4, and the base 1 is also provided with an unwinding driver 5 for driving the rotating shaft 4 to rotate, two support frames 6 extending upward to the vicinity of the axis of the rotating shaft 4 are symmetrically connected to the two sides of the first clamping seat 3, and an unwinding clamping roller 7 is rotatably connected to the top of any support frame 6, the two unwinding clamping rollers 7 are arranged perpendicular to the rotating shaft 4 and symmetrically distributed on both sides of the axis of the rotating shaft 4, and the roller surfaces of the two unwinding clamping rollers 7 are against each other to clamp the unwound core wire 8. The unwinding driver 5 drives the rotating shaft 4 to rotate, and the rotating shaft 4 drives the first clamping seat 3, the support frame 6 and the two unwinding clamping rollers 7 to rotate, twisting the core wire 8, and the core wire 8 is automatically unwound from the core wire bobbin 2 by the traction of the take-up mechanism.

[0021] The core wire tension control mechanism includes a crimping plate 9 which is fixedly connected to the bottom of the support frame 6 and is opposite to the first clamping seat 3 up and down, and a locking screw 10 which passes through each crimping plate 9 and is threadedly connected to the first clamping seat 3. The support frame 6 is rotatably connected to the outer edge of the first clamping seat 3. When the two locking screws 10 are tightened, the nut of the locking screw 10 will press down the corresponding crimping plate 9, and the crimping plate 9 drives the support frame 6 to swing inward, so that the two unwinding clamping rollers 7 at the top move toward each other to increase the clamping force on the core wire 8, thereby adjusting the tension of the core wire 8.

[0022] The tension of the core wire 8 can also be actually adjusted by connecting the unwinding clamping roller 7 through a magnetic powder tensioner, providing rotation resistance to the unwinding clamping roller 7, and adjusting the tension of the core wire 8 by adjusting the rotation resistance.

[0023] Adjusting the tension of the core wire 8 can realize the core wire 8 being wrapped with the covering wire in a stretched state, and when the core wire 8 retracts, the covering wires 32 on its surface can be driven to be closer to each other, and the core wire 8 can be effectively wrapped. Although the core wire 8 described in the utility model is a nylon filament, and its stretching ratio is relatively small, it can also drive the covering wires 32 to be closer when stretched and retracted.

[0024] The wire-receiving mechanism includes a wire-receiving roller 11 and a wire-receiving motor 12 for driving the wire-receiving roller 11 to rotate; first, the mechanism is arranged above the core wire unwinding and twisting mechanism to reel in the finished viscose-wrapped wire. Since the viscose-wrapped wire does not need to be twisted after being coated, the utility model adopts the wire-receiving roller 11 to directly reel in the wire, and the wire-receiving roller 11 is preferably arranged horizontally.

[0025] The wire wrapping mechanism is arranged between the core wire unwinding and twisting mechanism and the wire taking-up mechanism, and the wire wrapping mechanism includes a turntable 14 for supporting the wire wrapping bobbin 13, and the center of the turntable 14 is coaxial with the rotation center of the first clamping seat 3.

Two second clamping seats 30 are symmetrically arranged on the turntable 14 with the through hole 15 as the center, and the second clamping seat 30 is used to clamp the wire wrapping bobbin 13.

[0026] In actual use, the user can set one or two covered yarn bobbins 13 on the turntable 14 as needed.

[0027] The wire guiding mechanism is located between the wire wrapping mechanism and the wire taking-up mechanism, and the wire guiding mechanism includes a wire guiding frame 19, a lifting seat 20 is vertically slidably connected to the wire guiding frame 19, a wire guiding tube 21 is rotatably connected to the lifting seat 20, the wire guiding tube 21 is coaxially arranged with the through hole 15 at the center of the turntable 14, and a plurality of wire guiding holes 22 are evenly distributed circumferentially on the outer wall of the lower part of the wire guiding tube 21, a wire guiding motor 23 for driving the wire guiding tube 21 to rotate is arranged on the lifting seat 20, and a lifting driver 24 for driving the lifting seat 20 to move back and forth along the axial direction of the wire guiding tube 21 is arranged on the wire guiding frame 19. The rotation speed of the wire guiding tube 21 is equal to the rotation speed of the turntable 14. The speed of the lifting driver 24 driving the wire guiding tube 21 to rise is greater than the speed of driving the wire guiding tube 21 to descend.

[0028] In this embodiment, an electrostatic friction roller 25 is preferably arranged between the core wire unwinding and twisting mechanism and the wire covering and wrapping mechanism. The electrostatic friction roller 25 is in contact with the core wire 8 and rotates in the opposite direction relative to the core wire 8. A conductive guide wheel 26 is arranged on the upstream side of the take-up mechanism. The axle of the guide wheel 26 is grounded. The wrapped viscose covered wire is reversed by the guide wheel 26 and then wound onto the take-up yarn drum 27 on the take-up roller 11.

[0029] The electrostatic friction roller 25 is connected to a reverse motor 31, which drives the electrostatic friction roller 25 to rotate, generating friction with the core wire 8, so that the core wire 8 is charged with static electricity. The axle of the guide wheel 26 is grounded, which can release the charge on the twill coated wire, so that the cost twill coated wire is not charged.

[0030] like Figure 3 As shown, the middle part of the wire guide tube 21 in this embodiment is rotatably connected to the lifting seat 20, and a passive gear 28 is arranged on the outer periphery of the top of the wire guide tube 21. A driving gear 29 is connected to the output shaft of the wire guide motor 23, and the driving gear 29 is meshed with the passive gear 28. The wire guide motor 23 drives the wire guide tube 21 to rotate through gear transmission.

In actual application, the lifting driver 24 can also be a linear motor, a worm screw lifter or a cam mechanism.

[0032] The bearing 16 is an outer gear ring bearing, the turntable is fixedly connected to the outer gear ring of the bearing 16, and the wrapping driver 18 drives the outer gear ring of the bearing 16 to rotate through gear transmission. Using an outer gear ring bearing to support the turntable can improve the rotation stability of the turntable 14.
