Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a patterned core-spun yarn twisting and wrapping mechanism with a gradient color effect. Background Technology

[0002] Yarn is the main raw material for weaving garments, and its style greatly influences the overall effect of the clothing, especially for sweaters. Yarn color is one way to express its style. Currently, most conventional yarns are either single-color or multi-color blends. Single-color yarns have a monotonous hue and are typically used for formal wear, while multi-color patterned yarns are vibrant and lively, usually used for casual wear. Patterned yarns are usually made from blends of different colored fibers or through multiple dyeing processes. Blended yarns tend to have a more chaotic appearance, while dyed patterned yarns have poor colorfastness and are prone to fading. Yarns with gradient color effects, when made into garments, can give a clean, refined, and vibrant style, suitable for both casual and formal wear, thus possessing a promising market prospect. However, mass production of gradient color yarns is currently difficult.

[0003] Furthermore, the application document with publication number CN222758425U mentions a patterned core-spun yarn twisting and wrapping mechanism with a gradient color effect. This utility model controls the winding point of the cover yarn and the core yarn to move back and forth within a certain range along the axis of the core yarn, forming a sparse and dense wrapping effect on the outer surface of the core yarn. The colored cover yarn in the sparse part is lighter in color, and the colored cover yarn in the dense part is darker in color. By controlling the lifting speed of the lifting driver, the density change of the cover yarn winding on the surface of the core yarn can be controlled. Adjusting the density change to a positive spiral waveform change can obtain a gradient color effect. However, there are still some defects that need to be optimized. The specific defects are as follows: the guide tube in this structure cannot be replaced, which is not flexible enough when dealing with core yarns or cover yarns of different diameters. At the same time, because the cover yarn frequently rubs through the guide hole, long-term use may cause the hole diameter to increase, affecting the guide yarn accuracy.

[0004] Therefore, there is an urgent need to design a patterned core-spun yarn twisting and wrapping mechanism with gradient color effect that can solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a patterned core-spun yarn twisting and wrapping mechanism with a gradient color effect, in order to solve the problems that the guide tube in the current structure is not replaceable, which is not flexible enough when dealing with core yarns or cover yarns of different diameters. At the same time, due to the frequent friction of the cover yarn through the guide hole, long-term use may lead to an increase in the hole diameter, affecting the accuracy of the guide yarn.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A patterned core-spun yarn twisting and wrapping mechanism with gradient color effect includes a core yarn unwinding and twisting mechanism, a core yarn tension control mechanism, a take-up mechanism, a yarn covering and wrapping mechanism, a yarn guiding mechanism, and a support.

[0008] The above technical solutions enable the production of patterned core-spun yarns with unique gradient color effects, meeting market demand for diversified yarn products and enhancing product added value and market competitiveness.

[0009] The wire guide mechanism includes a wire guide frame, one end of which is connected to a ball screw. The wire guide frame is rotatably connected to a wire guide tube via a bearing. The wire guide tube has a groove at its top end and a threaded groove on its inner sidewall. A T-shaped wire guide cylinder is located inside the wire guide tube. Several wire guide holes are evenly distributed circumferentially on the lower outer wall of the T-shaped wire guide cylinder. A compression cylinder is located at the top of the T-shaped wire guide cylinder. A driven gear is located near the top end of the wire guide tube. The driven gear meshes with a driving gear. A core wire passes through the inside of the T-shaped wire guide cylinder. A cover wire is located inside the wire guide holes.

[0010] Through the above technical solution, the guide tube can rotate under the action of gears to realize the coating wire wrapped around the core wire. At the same time, the T-shaped guide tube inside the guide tube can be replaced through the extrusion cylinder thread engagement, which is convenient to adapt to coating wires of different diameters.

[0011] Furthermore, the bottom end of the T-shaped guide tube is provided with a square fixing post, one end of the square fixing post is provided with a round fixing post, and the groove is provided with slots that are adapted to the square fixing post and the round fixing post respectively.

[0012] The above technical solution facilitates the initial positioning of the T-shaped guide tube, followed by the assembly of the extrusion cylinder.

[0013] The extrusion cylinder is provided with threaded protrusions on the outside for matching the threaded groove, and the guide tube and T-shaped guide tube are both hollow.

[0014] The ball screw is driven by a servo motor;

[0015] The above technical solution uses an extrusion cylinder to limit the position of the T-shaped guide tube, preventing its displacement, while allowing it to rotate with the guide tube without hindering the wrapping of the core wire.

[0016] Furthermore, the core yarn unwinding and twisting mechanism includes a base and a core yarn bobbin. The base is provided with a clamping seat for clamping the core yarn bobbin. The clamping seat is rotatably connected to the base via a rotating shaft. The base is also provided with an unwinding driver for driving the rotating shaft to rotate. Two support frames extending upward to near the axis of the rotating shaft are symmetrically connected to both sides of the clamping seat. An unwinding clamping roller is rotatably connected to the top of either support frame. The two unwinding clamping rollers are arranged perpendicular to the rotating shaft and symmetrically distributed on both sides of the axis of the rotating shaft. The roller surfaces of the two unwinding clamping rollers abut against each other to clamp the unwound core yarn.

[0017] The above technical solution enables the unwinding and twisting of the core yarn bobbin, providing a core yarn with a certain degree of twist for the subsequent wrapping process;

[0018] Furthermore, the core wire tension control mechanism includes pressing plates that are fixedly connected to the bottom of the support frame and are vertically opposite to the card seat, and locking screws that pass through each pressing plate and are threaded to the card seat. The support frame is rotatably connected to the outer edge of the card seat. When the two locking screws are tightened, the nuts of the locking screws press down the corresponding pressing plates, and the pressing plates drive the support frame to swing inward, so that the two unwinding clamping rollers at the top move towards each other to increase the clamping force on the core wire, thereby adjusting the tension.

[0019] By using the above technical solution, the tension of the core wire is kept stable and product quality is guaranteed by adjusting and controlling the tension of the core wire during the unwinding process.

[0020] Furthermore, the take-up mechanism includes a take-up roller and a take-up motor that drives the take-up roller to rotate, and one end of the bracket is provided with a directional wheel.

[0021] Using the above technical solution, the patterned core-spun yarn, after being wrapped and twisted, is collected onto the take-up roller to complete the winding of the product.

[0022] Furthermore, the yarn covering and wrapping mechanism includes a yarn covering bobbin, a turntable for supporting the yarn covering bobbin, the center of the turntable being coaxial with the rotation center of the card seat, a through hole being provided in the center of the turntable, the turntable being rotatably connected to the support platform below it via a bearing, the support platform being fixedly installed, and a wrapping driver for driving the turntable to rotate being provided on the support platform, and two clamping seats being symmetrically arranged on the turntable with the through hole as the center;

[0023] The above technical solution enables the rotation of the covered yarn bobbin, providing power for the covered yarn to be wrapped around the core yarn, and controlling the wrapping speed and method of the covered yarn.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] This invention, through the design of a gradient color-effect patterned core-spun yarn twisting mechanism, achieves the following effects: 1. The T-shaped guide tube inside the guide tube is replaceable, allowing the twisting mechanism to flexibly handle various diameter yarns. When processing core yarns or cover yarns of different specifications, only the appropriate T-shaped guide tube needs to be replaced, without replacing the entire guide mechanism, greatly improving production flexibility and versatility, and meeting diverse production needs; 2. The replaceable T-shaped guide tube ensures that when the guide hole diameter changes due to long-term use, only a new T-shaped guide tube needs to be replaced to restore the guide accuracy, ensuring that the cover yarn can be accurately and stably wrapped around the core yarn, guaranteeing the stable and reliable quality of the gradient color-effect patterned core-spun yarn.

The cover yarn 7 is led out from the cover yarn wrapping mechanism 4 and also enters the guide yarn mechanism 5. In the guide yarn mechanism 5, the cover yarn wraps around the core yarn to form a patterned core-spun yarn with gradient color effect. Finally, the take-up mechanism 3 winds up the finished core-spun yarn.

[0037] Among them, such as Figure 2 and Figure 3 As shown, the wire guide mechanism 5 includes a wire guide frame 501. One end of the wire guide frame 501 is connected to a ball screw 502. The wire guide frame 501 is rotatably connected to a wire guide tube 503 via a bearing. The wire guide tube 503 has a groove 504 at its top end and a threaded groove 505 on its inner sidewall. A T-shaped wire guide cylinder 506 is located inside the wire guide tube 503.

The ball screw 502 is driven by a servo motor. The servo motor drives the ball screw 502 to rotate, which in turn moves the wire guide frame 501 up and down to adjust the wire guide position.

Two unwinding clamping rollers 107 are set perpendicular to the rotating shaft 104 and symmetrically distributed on both sides of the axis of the rotating shaft 104. The roller surfaces of the two unwinding clamping rollers 107 abut against each other to clamp the unwound core yarn 6. The unwinding driver 105 on the base 101 drives the rotating shaft 104 connected to the card holder 103 to rotate. The card holder 103 drives the core yarn bobbin 102 to rotate, realizing the unwinding of the core yarn. The two unwinding clamping rollers 107 on the top of the support frame on both sides of the card holder 10 clamp the unwound core yarn 6 and assist the core yarn 6 to be output stably during the unwinding process.

[0041] like Figure 1 and Figure 4 As shown, the core wire tension control mechanism 2 includes pressing plates 201 fixedly connected to the bottom of the support frame 106 and vertically opposite to the card holder 103, and locking screws 202 that pass through each pressing plate 201 and are threadedly connected to the card holder 103. The support frame 106 is rotatably connected to the outer edge of the card holder 103. When the two locking screws 202 are tightened, the nuts of the locking screws 202 press down the corresponding pressing plates 201. The pressing plates 201 drive the support frame 106 to swing inward, causing the two unwinding clamping rollers 107 at the top to move towards each other, increasing the tension on the core wire 6. The clamping force adjusts the tension. The support frame 106 is rotatably connected to the outer edge of the card holder 103. The pressing plate 201 is fixedly connected to the bottom of the support frame 106 and is vertically opposite to the card holder 103. The locking screw 202 passes through the pressing plate 201 and is threadedly connected to the card holder 103. When the two locking screws 202 are tightened, the nuts of the screws 202 will press down the corresponding pressing plate 201. The pressing plate 201 drives the support frame 106 to swing inward, causing the two unwinding clamping rollers 107 at the top to move towards each other, increasing the clamping force on the core wire, thereby adjusting the core wire tension.

[0042] like Figure 1 and Figure 6As shown, the take-up mechanism 3 includes a take-up roller 301 and a take-up motor 302 that drives the take-up roller 301 to rotate. One end of the bracket 8 is provided with a directional wheel 303. First, the take-up roller 301 is put onto the yarn bobbin. Then, the take-up motor 302 drives the take-up roller 301 to rotate. The directional wheel 303 at one end of the bracket 8 guides the patterned core-spun yarn and collects the patterned core-spun yarn that has been wrapped and twisted onto the yarn bobbin.

[0043] like Figure 1 and Figure 5 As shown, the covering yarn wrapping mechanism 4 includes a covering yarn bobbin 401 and a turntable 402 for supporting the covering yarn bobbin 401. The center of the turntable 402 is coaxial with the rotation center of the clamping seat 103. A through hole 403 is provided in the center of the turntable 402. The turntable 402 is rotatably connected to the support platform 404 below it through a bearing. The support platform 404 is fixedly installed. A wrapping driver 405 for driving the turntable 402 to rotate is also provided on the support platform 404. Two clamping seats are symmetrically arranged on the turntable 402 with the through hole 403 as the center. The covering yarn bobbin 401 is placed on the turntable 402 and fixed in position by the clamping seats. Then the wrapping driver 405 drives the turntable 402 to rotate. The turntable 402 drives the covering yarn bobbin 401 to rotate, and the covering yarn 7 is led out from the covering yarn bobbin 401.

[0044] The working process of this utility model is as follows: When using this cultural dissemination and display device, firstly, the yarn bobbin is fitted onto the take-up roller 301. Then, the core yarn bobbin 102 is placed on the clamping seat 103. The core yarn 6 is guided through the two unwinding clamping rollers 107, through the through hole 403 on the turntable 402, through the T-shaped guide bobbin 506, and through the directional wheel 303, and wound onto the yarn bobbin. At the same time, the covering yarn bobbin 401 is fixed in the clamping seat on the turntable 402. The covering yarn 7 is led out from the outside of the guide hole 507 and fed into the guide tube 503 and wound onto the core yarn 6.

[0045] Then, the twisting and wrapping mechanism is activated. The take-up motor 302 drives the take-up roller 301 to slowly wind up the yarn, the wrapping driver 405 drives the turntable 402 to rotate rapidly, and the guide motor drives the guide tube 503 to rotate synchronously with the turntable 402. At the same time, the servo motor drives the ball screw 502 to move the guide tube 503 up and down reciprocally, causing the coated yarn 7 to move back and forth along the axis of the core yarn 6 outside the core yarn 6. This makes the wrapping spacing of the coated yarn 7 outside the core yarn 6 vary, creating a gradient color effect. The unwinding driver 105 drives the holder 103 to rotate slowly, twisting the core yarn 6. The twisting of the core yarn 6 is used to twist the fuzz of the coated yarn 7, improving the bonding force between the coated yarn 7 and the core yarn 6.

[0046] The interior of the wire guide tube 503 can be exposed by rotating the extrusion cylinder 508. At this time, the upper T-shaped wire guide tube 506 separates it from the wire guide tube 503. Then, a new T-shaped wire guide tube 504 can be replaced according to the actual situation to adapt to different diameters of covered wire and core wire.

[0047] All standard parts used in this application can be purchased from the market. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is through a controller. The control circuit of the controller can be realized by a person skilled in the art through simple circuit connection. It is common knowledge in the field. Therefore, this application will not explain the control method and circuit connection in detail.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
