Technical Field
[0001] This utility model relates to the field of textile processing technology, specifically a drafting device for rabbit hair coarse spinning yarn. Background Technology
[0002] When rabbit hair fibers are spun into yarn, a drafting device is needed to continuously draft and control the rotation of the rabbit hair fibers, thereby spinning them into yarn. The completed spun yarn is then wound up.
[0003] However, the existing drawing equipment is large in size, which cannot match the production volume of small workshops. In addition, the price of the drawing equipment is high, which increases the production cost and makes it difficult to meet the needs of use. Utility Model Content
[0004] The purpose of this invention is to provide a drafting device for rabbit wool coarse yarn, which aims to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: The rabbit wool coarse yarn drafting device includes a base plate, on which two upright plates are provided. A rotating shaft and a bobbin are provided on the two upright plates. The bobbin is located above the rotating shaft, and both the bobbin and the rotating shaft are rotatably connected to the upright plates. A motor for driving the rotating shaft is provided on the base plate and on one side of the upright plates. The rotating shaft and the bobbin are driven by a synchronous pulley and a synchronous belt. A groove is formed on the outer surface of one end of the bobbin, and a guide wire is provided at one end of the bobbin. A guide groove is formed on the guide wire. A side plate is provided above the motor. The side plate and the upright plates... The device is fixedly connected to a side plate, with a disc rotatably connected to the disc. A fixing plate is mounted on the disc, and a round rod is rotatably connected to the upper end of the fixing plate. A motor for driving the round rod to rotate is mounted on one side of the fixing plate. A positioning groove is provided on the disc. A cover is provided on the lower surface of the fixing plate. The device also includes a button with a vertical part and a horizontal part. The vertical part of the button passes through the fixing plate and is slidably connected to it. The horizontal part is located inside the cover. A spring is provided inside the cover and below the horizontal part. A positioning rod is provided on the upper surface of the horizontal part. A through hole for the positioning rod to pass through is provided on the fixing plate.
[0006] Preferably, one end of the spool is threaded with a cap, the cap having a central hole at its center, and the two ends of the central hole being rounded.
[0007] Preferably, both the cap and the wire are made of nylon plastic.
[0008] Preferably, a slit is provided on the round rod.
[0009] Preferably, a surrounding plate is provided between the bottom plate and the side plate, and the outer surface of the surrounding plate is provided with heat dissipation grooves.
[0010] The beneficial effects of this utility model are:
[0011] This type of drafting device is relatively small in size and simple in structure, with low equipment cost. It can meet the production needs of small workshops. At the same time, by controlling the synchronous and unidirectional but different speed rotation of the bobbin and the round rod, the coarse yarn can be effectively twisted into yarn before being wound up by the round rod. This avoids the rabbit hair fiber being wound up before it is processed into coarse yarn, which helps to ensure product quality. Attached Figure Description

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.
[0019] like Figure 1-5As shown, a rabbit wool coarse yarn drawing device includes a base plate 2, on which two upright plates 3 are mounted. A rotating shaft 4 and a bobbin 5 are mounted on the two upright plates 3. The bobbin 5 is located above the rotating shaft 4, and both the bobbin 5 and the rotating shaft 4 are rotatably connected to the upright plates 3. A motor 6 for driving the rotating shaft 4 is mounted on the base plate 2 and located on one side of the upright plates 3. The rotating shaft 4 and the bobbin 5 are connected by a synchronous pulley 7 and a synchronous belt 8. A groove 9 is formed on the outer surface of one end of the bobbin 5, and a guide member 10 is provided at one end of the bobbin 5. A guide groove 11 is formed on the guide member 10. A side plate 12 is mounted above the motor 6 and is fixedly connected to the upright plates 3. A rotatable component is rotatably connected to the side plate 12. A disc 13 is provided with a fixing plate 14. A round rod 15 is rotatably connected to the upper end of the fixing plate 14. A motor 16 for driving the round rod 15 to rotate is provided on one side of the fixing plate 14. A positioning groove 17 is provided on the disc 13. A cover 18 is provided on the lower surface of the fixing plate 14. A button 19 is also provided. The button 19 has a vertical part and a horizontal part. The vertical part of the button 19 passes through the fixing plate 14 and is slidably connected to the fixing plate 14. The horizontal part is located inside the cover 18. A spring 20 is provided inside the cover 18 and below the horizontal part. A positioning rod 21 is provided on the upper surface of the horizontal part. A through hole for the positioning rod 21 to pass through is provided on the fixing plate 14.
[0020] Before processing the rabbit hair fiber 1 into coarse yarn, first take an auxiliary rope and manually twist the front end of the rabbit hair fiber 1 into a rope. Then connect one end of the auxiliary rope to the front end of the rabbit hair fiber 1, and then insert the other end of the auxiliary rope into the yarn spool 5. Then lead the auxiliary rope out of the yarn spool 5 from the yarn groove 9. Next, let the auxiliary rope enter the guide groove 11 of the conductor 10. Then tie the auxiliary rope to the round rod 15. At this time, the preparation work is completed.
[0021] When processing rabbit hair fiber 1 into coarse yarn, motor 16 and motor 26 need to be started simultaneously. Motor 16 drives the rotating shaft 4 to rotate, and then drives the yarn wheel to rotate through the synchronous pulley 7 and synchronous belt 8. Since the rabbit hair fiber 1 passes through the groove 9 on the yarn spool 5, and the other end of the rabbit hair fiber 1 is in the worker's hand, the part of the rabbit hair fiber 1 in the worker's hand will not rotate. Therefore, when the yarn spool 5 rotates, it can make the rabbit hair fiber 1 rotate and form coarse yarn. At the same time, motor 26 drives the round rod 15 to rotate. When the round rod 15 rotates, it can first wind up the auxiliary rope tied to the round rod 15. When the auxiliary rope is completely wound up, the coarse yarn of the rabbit hair fiber 1 will begin to be wound up. Since the rabbit hair fiber 1 is fluffy, the worker only needs to continuously and relatively slowly release the rabbit hair fiber 1 to keep the coarse yarn in a relatively fine state.
[0022] The feeding operation of rabbit hair fiber 1 is a manual operation and is also existing technology, so it will not be described in detail here.
[0023] To ensure that the rabbit hair fiber 1 can be effectively spun into yarn, it is necessary to control the rotation speed of the round rod 15 and the bobbin 5. The rotation speed of the bobbin 5 is greater than that of the round rod 15. The rotation speed of the bobbin 5 is 300 r / min, and the rotation speed of the round rod 15 is 100 r / min. The rotation direction of the round rod 15 is the same as that of the bobbin 5. By controlling the rotation speed difference between the bobbin 5 and the round rod 15, it is possible to ensure that the rabbit hair fiber 1 can be effectively spun into yarn and that the spun yarn can be wound on the round rod 15. For other types of fibers, appropriate rotation speeds can be selected for the bobbin 5 and the round rod 15 respectively.
[0024] During the process of coarsely spinning rabbit hair fiber 1 into yarn, the coarsely spun yarn is wound onto the round rod 15 through the guide groove 11 on the conductor 10. After a section of rabbit hair fiber 1 is completely coarsely spun into yarn and wound onto the round rod 15, motor 1 6 and motor 2 16 stop operating. Then, press button 19 downwards to completely remove the positioning rod 21 from the positioning groove 17 on the disc 13. At this time, due to the lack of restriction from the positioning rod 21, the disc 13 can rotate on the side plate 12. The disc 13 can be rotated so that the round rod 15 is facing away from the conductor 10. At this time, the yarn on the round rod 15 can be easily removed. When it is necessary to wind up the next section of coarsely spun rabbit hair fiber 1 yarn, simply rotate the disc 13. When the positioning groove 17 on the disc 13 moves to the position of the positioning rod 21, under the action of spring 20, the positioning rod 21 will be pushed into the positioning groove 17 through button 19, thereby completing the adjustment of the position of the disc 13.
[0025] Furthermore, one end of the bobbin 5 is threaded with a nut 22, and a central hole 23 is provided at the center of the nut 22. The two ends of the central hole 23 are rounded. Through the central hole 23, the amplitude of the bobbin 5's runout can be reduced, and the friction between the bobbin 5 and the bobbin 5 can be reduced.
[0026] Furthermore, both the spiral cap 22 and the conductor 10 are made of nylon plastic, which further reduces the friction between the coarse spun yarn and the bobbin 5.
[0027] Furthermore, a slit is provided on the round rod 15 to facilitate the attachment of an auxiliary rope to the round rod 15 through the slit.
[0028] Furthermore, a surrounding plate 24 is provided between the bottom plate 2 and the side plate 12, and heat dissipation grooves are provided on the outer surface of the surrounding plate 24.
[0029] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
