Description

Technical Field

[0001] The present invention relates to the technical field of yarn preparation devices, and particularly relates to a device and method for preparing wool-yak cashmere blended fabric yarns. Background Art

[0002] Wool-yak cashmere blended yarns are high-grade textile materials that combine the characteristics of wool and yak cashmere. Blending wool and yak cashmere in a certain proportion can give full play to their respective advantages, making the fabric more comfortable and extensible, while also improving thermal insulation, enhancing durability, and endowing the fabric with a more unique feel and appearance.

[0003] When preparing existing wool-yak cashmere blended fabric yarns, the mixing of wool and yak cashmere is divided into two cases. One is: after the wool and yak cashmere are carded, the wool and yak cashmere are doped and mixed together, and then stretched and twisted to form wool-yak cashmere blended yarns. Or: the wool and yak cashmere are stretched and twisted separately to form yarns, and then multiple wool yarns and multiple yak cashmere yarns are combined together by twisting to form wool-yak cashmere blended yarns. However, the existing preparation of wool-yak cashmere blended fabric yarns cannot satisfy the synchronous operation of the above two working conditions at the same time. Summary of the Invention

[0004] Technical Problem to be Solved

[0005] In view of the above-mentioned drawbacks of the prior art, the present invention provides a device and method for preparing wool-yak cashmere blended fabric yarns, which can solve the problem that the prior art cannot simultaneously prepare blended yarns of mixed wool and yak cashmere and blended yarns of composite wool yarns and yak cashmere yarns.

[0006] Technical Solution

[0007] To achieve the above object, the present invention is realized through the following technical solutions:

[0008] The present invention provides a device for preparing wool-yak cashmere blended fabric yarns, including a frame, on which a sealed box, a twisting mechanism, a stranding mechanism, and a winding mechanism are sequentially installed. Inside the sealed box, a stretching mechanism for stretching the raw materials is installed. The stretching mechanism transports the stretched raw materials out of the sealed box during the stretching process. The twisting mechanism is used to twist the stretched raw materials into single-strand yarns. A plurality of the sealed boxes and twisting mechanisms are arranged in parallel. All the plurality of twisting mechanisms guide the single-strand yarns into the stranding mechanism. The stranding mechanism is used to strand a plurality of single-strand yarns into composite yarns and guide them to the winding mechanism to complete winding.

[0009] Furthermore, a stretching channel is provided inside the sealed box. The stretching mechanism is arranged in multiple groups and linearly installed above the stretching channel. One end of the sealed box away from the twisting mechanism is equipped with a blower, the air outlet of the blower faces the side of the twisting mechanism, a feeding port is arranged above the air outlet of the blower on the sealed box, and a guide plate is arranged inside the sealed box between the feeding port and the stretching channel.

[0010] Furthermore, the stretching mechanism includes a guide rod installed on the inner wall of the sealed box. A sliding rod is slidably installed on the surface of the guide rod. The lower end of the sliding rod is connected with a stretching plate. Uniformly distributed separating teeth are arranged on the lower surface of the stretching plate. The stretching mechanism also includes a turntable rotatably installed in the sealed box. A connecting rod is rotatably connected to a non - central position on the surface of the turntable. The other end of the connecting rod is rotatably connected to the upper end of the sliding rod. Concentrically distributed transmission parts are also installed on the turntable. A motor A is installed on the inner wall of the sealed box, and the motor A is in transmission connection with the transmission parts.

[0011] Furthermore, the guide rod is arranged in an inclined shape, and the height on the side close to the feeding port is higher than the other end.

[0012] Furthermore, the sliding directions of two adjacent stretching plates are opposite. The separating teeth arranged on the surfaces of two adjacent stretching plates are stagger - distributed. Slots are arranged on the surfaces of two adjacent stretching plates, and the separating teeth and slots on two adjacent stretching plates correspond to each other.

[0013] Furthermore, both the twisting mechanism and the wire - twisting mechanism are composed of a rotating mechanism and a traction mechanism. The rotating mechanism is used to clamp and fix the stretched raw materials and apply a mechanical rotating force to the raw materials. The traction mechanism is used to drive the linear sliding of the rotating mechanism to elongate the yarn.

[0014] Furthermore, the traction mechanism includes a support frame installed on the frame. A lead screw is inserted into the support frame. A motor C is installed on the support frame, and the motor C is in transmission connection with the lead screw. A sliding table is installed on the lead screw in a matching manner. The rotating mechanism is installed on the sliding table.

[0015] Furthermore, the rotating mechanism includes a base installed on the surface of the sliding table. A rotating ring is rotatably installed on the base. An air pipe is installed on the rotating ring. The air pipe is arranged in a "U" - shaped structure. The two openings on both sides of the air pipe are symmetrically distributed and sliding blocks are installed inside both of them. A pressure pump is connected to the air pipe. A motor B is also installed on the base. A control gear is installed on the output shaft of the motor B. Tooth patterns are arranged on the outer surface of the rotating ring and are meshed with the control gear.

[0016] Furthermore, a guide wheel is connected to one end of the support frame away from the sealed box.

[0017] A preparation method for a wool-yak cashmere blended fabric yarn, comprising the following steps:

[0018] Step 1: Add wool raw materials, yak cashmere raw materials or wool-yak cashmere mixed raw materials into a sealed box;

[0019] Step 2: Stretch the raw materials in the sealed box through a stretching mechanism and output the stretched raw materials;

[0020] Step 3: Twist the stretched raw materials through a twisting mechanism to form wool yarn, or yak cashmere yarn, or wool-yak cashmere blended yarn, and divert the twisted yarn into a stranding mechanism;

[0021] Step 4: Strand and composite the wool yarn, yak cashmere yarn, and wool-yak cashmere blended yarn through a stranding mechanism to form a composite yarn;

[0022] Step 5: Wind up the composite yarn through a winding mechanism.

[0023] Beneficial effects

[0024] The technical solution provided by the present invention has the following beneficial effects compared with the known prior art:

[0025] Through the structural settings of the sealed box, stretching mechanism, twisting mechanism, stranding mechanism, and winding mechanism, after the raw materials are put into the sealed box, the stretching mechanism stretches the raw materials and conveys the stretched raw materials to one side of the twisting mechanism. Then, the twisting mechanism twists the stretched raw materials, and under the action of rotation and traction, the fibers form yarn. Finally, the winding mechanism winds up the yarn to complete the preparation of the yarn.

[0026] Among them, the raw materials put into the sealed box can be wool raw materials, or yak cashmere raw materials, or wool-yak cashmere mixed raw materials, further enabling the corresponding twisting mechanism to twist into wool yarn, or yak cashmere yarn, or wool-yak cashmere blended yarn;

[0027] And when the single-strand yarn twisted by each twisting mechanism is diverted to the stranding mechanism, the stranding mechanism can strand multiple single-strand yarns, making the wool yarn and yak cashmere yarn composite into a wool-yak cashmere blended yarn, or directly composite multiple wool-yak cashmere blended yarns into a mixed yarn;

[0028] Through the above functions, when the device prepares the wool-yak cashmere blended yarn, it can realize the combined operation of multiple working conditions, thereby increasing the working efficiency of the device. And when the device composites multiple wool yarns and multiple yak cashmere yarns into a wool-yak cashmere blended yarn, after the wool yarn and yak cashmere are twisted, they can be quickly and automatically stranded and composite without disassembly.

DETAILED DESCRIPTION

[0037] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0038] The present invention will be further described below in conjunction with the embodiments.

[0039] Embodiment:

[0040] Please refer to the attached Figures 1-6 , this solution proposes a device for preparing wool yak cashmere blended fabric yarns. A sealing box 2, a twisting mechanism 3, a stranding mechanism 4, and a winding mechanism 5 are sequentially installed on a frame 1. By adding wool and yak cashmere raw materials into the sealing box 2 and running a stretching mechanism 7 inside the sealing box 2, the wool and yak cashmere raw materials are stretched, so that the wool and yak cashmere raw materials are gradually mixed together during the stretching process, and the arrangement of wool fibers and yak cashmere fibers in space becomes more regular and orderly, forming a uniform mixture. Then, the twisting mechanism 3 twists the mixture of wool fibers and yak cashmere fibers, so that the wool fibers and yak cashmere fibers form wool yak cashmere blended yarns under the action of rotation and traction.

[0041] Moreover, multiple sealing boxes 2 are provided on the frame 1, and the twisting mechanisms 3 are arranged side by side. Wool raw materials or yak cashmere raw materials can be separately added to each group of sealing boxes 2, or wool and yak cashmere raw materials can be added in combination. Further, when the corresponding twisting mechanism 3 of each group of sealing boxes 2 is working, it can twist wool yarns, or yak cashmere yarns, or wool yak cashmere blended yarns. Finally, the yarns separately twisted by each group of twisting mechanisms 3 are all guided to pass through the stranding mechanism 4. The stranding mechanism 4 strands and composites the wool yarns, yak cashmere yarns, and wool yak cashmere blended yarns to form the composite connection of multiple final yarns. Finally, it is connected to the winding mechanism 5, and the winding mechanism 5 winds the finished yarns to complete the preparation of the composite yarns.

[0042] Specifically, a stretching channel 202 is provided inside the sealed box 2, and multiple stretching mechanisms 7 are linearly installed above the stretching channel 202. The stretching mechanism 7 includes a guide rod 701 installed on the inner wall of the sealed box 2, and the guide rod 701 is inclined. A sliding rod 702 is slidably installed on the surface of the guide rod 701. The lower end of the sliding rod 702 is connected to a stretching plate 703, and evenly distributed separating teeth 704 are provided on the lower surface of the stretching plate 703. The stretching mechanism 7 further includes a turntable 705 rotatably installed inside the sealed box 2. A connecting rod 706 is hingedly installed at a non-central position on the surface of the turntable 705, and the other end of the connecting rod 706 is rotatably connected to the upper end of the sliding rod 702. Concentrically distributed transmission parts 707 are also installed on the turntable 705. A motor A 708 is installed on the inner wall of the sealed box 2, and the motor A 708 is in transmission connection with the transmission parts 707. A blower 6 is installed at one end of the sealed box 2 away from the twisting mechanism 3. The air outlet of the blower 6 faces the side of the twisting mechanism 3. A feeding port 201 is provided on the sealed box 2, and the feeding port 201 is located above the air outlet of the blower 6. And a flow guide plate 203 is provided inside the sealed box 2 between the feeding port 201 and the stretching channel 202. When the device is in use, wool raw materials or yak wool raw materials or mixed wool and yak wool raw materials are put into the sealed box 2 through the feeding port 201, and the blower 6 is turned on to operate. The blower 6 blows the raw materials in the feeding port 201 towards the stretching channel 202 side, so that the raw materials are conveyed to the lower part of the stretching mechanism 7 under the guiding action of the flow guide plate 203, and the raw materials are stretched by the stretching mechanism 7.

[0043] More specifically, when the motor A 708 is turned on to operate, the motor A 708 drives the turntable 705 to rotate through the transmission parts 707, and further controls the connecting rod 706 connected to the turntable 705 to rotate, so that the connecting rod 706 pulls the sliding rod 702 to slide on the surface of the guide rod 701. The height of the guide rod 701 on the side close to the feeding port 201 is higher than the other end. When the sliding rod 702 slides upward on the surface of the guide rod 701, the height of the stretching plate 703 will be lifted, and further, under the action of the air flow, the raw materials in the feeding port 201 will be blown to the lower part of the stretching plate 703. During the continuous rotation of the turntable 705, the sliding rod 702 will be pulled by the connecting rod 706 to slide reciprocally on the surface of the guide rod 701. Further, when the sliding rod 702 slides downward on the surface of the guide rod 701, it will control the stretching plate 703 to press down, and the separating teeth 704 will be inserted into the raw materials below. During the continuous downward sliding of the stretching plate 703, the separating teeth 704 will push the raw materials forward, and during the pushing process, the raw materials will be combed, making the arrangement of wool fibers and yak wool fibers more regular and neat.

[0044] The plurality of stretching mechanisms 7 are connected to each other through transmission members 707, and the two sets of stretching plates 703 in two adjacent stretching mechanisms 7 slide in opposite directions, the sparse teeth 704 arranged on the surfaces of the two adjacent stretching plates 703 are staggered, and the surfaces of the two sets of stretching plates 703 are provided with slots 709, and the sparse teeth 704 on the surface of one set of stretching plates 703 correspond to the slots 709 on the surface of the other set of stretching plates 703. When the first set of stretching plates 703 slide downward, the second set of stretching plates 703 will slide upward synchronously, so that the first set of stretching plates 703 will stretch the raw materials below to the bottom of the next set of stretching plates 703, and further, when the first set of stretching plates 703 slide upward, the second set of stretching plates 703 will slide downward, and the sparse teeth 704 on the second set of stretching plates 703 will penetrate the slots 709 on the surface of the first set of stretching plates 703 and be inserted into the raw materials below. Furthermore, when the first set of stretching plates 703 are reset, the stretched raw materials are intercepted by the second set of stretching plates 703, and when the second set of stretching plates 703 slide downward, the intercepted raw materials are further stretched and pushed forward, so that the raw materials are continuously stretched and pushed forward on the stretching channel 202, and finally the stretched raw materials pass through the sealing box 2.

[0045] The difference is that the twisting mechanism 3 and the stranding mechanism 4 are both composed of a rotating mechanism 8 and a traction mechanism 9. When the stretched raw material passes through the sealing box 2, the stretched raw material is clamped and fixed by the rotating mechanism 8, so that the rotating mechanism 8 can twist the fibers together to form yarn during the rotation process. At the same time, the traction mechanism 9 is running, which can drive the rotating mechanism 8 to slide linearly, and further make the rotating mechanism 8 stretch the yarn during the twisting process, so as to realize the continuous production of yarn. And in the process of the stretching mechanism 7 stretching the raw material, the continuous supply of the raw material can be guaranteed to avoid the raw material from breaking during the twisting process.

[0046] The traction mechanism 9 includes a support frame 901 mounted on the frame 1, a screw rod 902 is inserted into the support frame 901, a motor C903 is mounted on the support frame 901, the output shaft of the motor C903 is in transmission connection with the screw rod 902, a slide 904 is adapted to be mounted on the screw rod 902, and the rotating mechanism 8 is mounted on the slide 904. When the motor C903 is turned on, the screw rod 902 is driven to rotate inside the slide 904, and the slide 904 is further controlled to slide linearly, so as to achieve the position adjustment of the rotating mechanism 8.

[0047] The rotating mechanism 8 includes a base 801 installed on the surface of the sliding table 904, and a rotating ring 802 is rotatably installed on the base 801. After the raw material in the sealing box 2 is stretched, a part of the raw material is twisted out and passed through the rotating ring 802. An air pipe 803 is installed on the rotating ring 802. The air pipe 803 is arranged in a "U" shape, the two openings on both sides of the air pipe 803 are symmetrically distributed, and a pressing block 804 is slidably installed inside each of them. At the same time, a pressure pump 805 is connected to the air pipe 803. When the twisted part of the raw material is located between the two pressing blocks 804, the pressure pump 805 is started to operate. The pressure pump 805 pressurizes the inside of the air pipe 803, so that the pressing blocks 804 slide out under the action of the air pressure in the air pipe 803, and the twisted part of the raw material is clamped and fixed by the two pressing blocks 804, realizing the loading of the raw material on the rotating mechanism 8. A motor B806 is also installed on the base 801. A control gear 807 is installed on the output shaft of the motor B806. The outer surface of the rotating ring 802 is provided with tooth patterns and is meshed with the control gear 807. Further, after the motor B806 is started, it drives the control gear 807 to mesh with the rotating ring 802 to rotate, so that the rotating ring 802 forms a rotational mechanical force on the clamped and fixed raw material during the rotation process. And during the process of the rotating mechanism 8 moving away from the sealing box 2, the raw material in the sealing box 2 is twisted into a single yarn away from it.

[0048] And when the rotating mechanism 8 slides on the traction mechanism 9 to the farthest distance away from the sealing box 2, the two pressing blocks 804 are controlled by the pressure pump 805 to release the clamping of the yarn. Then, the sliding table 904 is driven by the motor C903 to slide towards the sealing box 2 side, realizing the reset of the rotating mechanism 8, and clamping the untwisted part of the raw material in the sealing box 2 again, and repeating the above process to realize the continuous twisting of the raw material.

[0049] It should be noted that a guide wheel 905 is connected to one end of the support frame 901 away from the sealing box 2. The yarn twisted by the rotating mechanism 8 is guided to one side of the stranding mechanism 4 through the guide wheel 905, further winding multiple twisted single yarns together and fixing them on the rotating mechanism 8 in the stranding mechanism 4. Through the coordinated operation of the rotating mechanism 8 and the traction mechanism 9, the winding of multiple yarns can be realized, and they are intertwined with each other, and finally the preparation of the wool-yak cashmere blended yarn is completed.

[0050] A method for preparing a wool-yak cashmere blended fabric yarn includes the following steps:

[0051] Step 1: Add wool raw material, yak cashmere raw material or wool-yak cashmere mixed raw material into the sealing box 2;

[0052] Step 2: Stretch the raw material in the sealing box 2 through the stretching mechanism 7 and output the stretched raw material;

[0053] Step 3: Twist the stretched raw materials through the twisting mechanism 3 to form wool yarn, or yak cashmere yarn, or wool-yak cashmere blended yarn, and divert the twisted yarn into the stranding mechanism 4;

[0054] Step 4: Strand and compound the wool yarn, yak cashmere yarn, and wool-yak cashmere blended yarn through the stranding mechanism 4 to form a composite yarn;

[0055] Step 5: Wind up the composite yarn through the winding mechanism 5.

[0056] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
