Description

Technical Field

[0001] This utility model relates to the field of yarn guiding device technology, and in particular to a yarn guiding device for a spinning machine. Background Technology

[0002] A spinning machine is a textile device that uses needles to form loops from various raw materials and yarns, which are then linked together to form knitted fabrics. After forming the yarn, the spinning machine needs to wind it onto a take-up bobbin to form a yarn package for subsequent transportation and other processing. To prevent the yarn from overlapping in the same position on the take-up bobbin, a yarn guiding device is installed. This device reciprocates, causing the yarn to be wound onto the take-up bobbin in a cross-winding manner, preventing it from remaining in the same position.

[0003] For example, Chinese Patent Publication No. (CN208219069U) discloses a yarn guiding device for a spinning machine, which describes: "It includes a fixed base, a yarn guiding frame, a yarn guiding needle, a fixing bolt, a nut, a movable plate, a first rubber pad, a second rubber pad, a yarn guiding needle seat, a slide groove, and a pulley. The fixed base is provided with a yarn guiding frame on its surface. The top of the yarn guiding frame is provided with a yarn guiding needle, and the bottom of the yarn guiding needle is provided with a yarn guiding needle seat. The top surface of the yarn guiding frame is provided with a movable plate. The inside of the yarn guiding frame is provided with a slide groove. The movable plate and the yarn guiding frame are slidably connected by a pulley. The yarn guiding needle seat and the yarn guiding frame are fixedly connected by a fixing bolt. One end of the fixing bolt is also provided with a nut. This yarn guiding device for a spinning machine is connected to the yarn guiding frame by a fixed bolt threaded connection, which makes it easy to install and disassemble the yarn guiding needle. The movable connection between the movable plate and the yarn guiding frame allows the number of yarn guiding needles on the surface of the yarn guiding frame to be adjusted according to the actual number."

[0004] In summary, the device also has the following technical problems: The device achieves adjustment by increasing the number of guide needles, but the spinning process is continuous. If the guide needles are increased in the above way, the spinning machine needs to be stopped for a long time to install the guide needles, which will lead to a reduction in spinning efficiency. Therefore, it is necessary to propose a yarn guiding device for a spinning machine to provide a new technical solution to solve the technical problems mentioned in the above patent. Utility Model Content

[0005] Based on this, it is necessary to provide a yarn guiding device for a spinning machine to address the aforementioned technical problems. This device uses a fixed ear plate in conjunction with an adjustment mechanism. After the servo motor is turned on, it drives the threaded rod to rotate. The rotation of the threaded rod can drive the side support rod to pull the scissor-type isolation frame to retract or push the scissor-type isolation frame to extend. When the scissor-type isolation frame extends or retracts, the central positioning rods in its middle can move closer or further apart, thereby causing the central yarn guide frame to gather or disperse the yarn. In this way, the yarn spacing can be quickly adjusted, which greatly improves the yarn spacing adjustment compared to existing devices.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0026] As described in the background art, the above-mentioned device achieves adjustment by increasing the number of guide needles. However, the spinning process is continuous. If the above method is used to increase the number of guide needles, the spinning machine needs to be stopped for a long time to install the guide needles, which will lead to a reduction in spinning efficiency.

[0027] To solve this technical problem, this utility model provides a yarn guiding device for a spinning machine.

[0028] For details, please refer to Figures 1-2 The yarn guiding device of the spinning machine specifically includes a machine body support frame 1, fixed ear plates 2 for connecting with the machine body are provided on both sides of the machine body support frame 1, adjustment mechanisms 3 are provided on the upper and lower sides of the machine body support frame 1, and a support structure 4 is provided on the front of the machine body support frame 1.

[0029] The fixed ear plate 2 includes two servo motors 5 fixedly connected to the upper end of the body support frame 1, and a fixed block 8 is fixedly connected to the bottom surface of the body support frame 1.

[0030] The yarn guiding device for a spinning machine provided by this utility model has a fixed ear plate 2 and an adjustment mechanism 3. After the servo motor 5 is turned on, it drives the threaded rod 6 to rotate. The rotation of the threaded rod 6 can drive the side support rod 11 to pull the scissor-type isolation frame 15 to retract or push the scissor-type isolation frame 15 to extend. When the scissor-type isolation frame 15 extends or retracts, the central positioning rod 16 in its middle can move closer or further away from each other, thereby causing the central yarn guide frame 18 to pull the yarn together or disperse. In this way, the yarn spacing can be quickly adjusted, which is a great improvement over the existing device in terms of yarn spacing adjustment.

[0031] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0032] Please refer to Figures 2-4 A yarn guiding device for a spinning machine includes a machine body support frame 1, fixed ear plates 2 for connecting to the machine body are provided on both sides of the machine body support frame 1, adjustment mechanisms 3 are provided on the upper and lower sides of the machine body support frame 1, and a support structure 4 is provided on the front of the machine body support frame 1.

[0033] The fixed ear plate 2 includes two servo motors 5 fixedly connected to the upper end of the body support frame 1, and a fixed block 8 is fixedly connected to the bottom surface of the body support frame 1.

[0034] Specifically, the output end of the servo motor 5 is connected to a threaded rod 6, the surface of the threaded rod 6 is threadedly connected to a first fixed seat 7, the inside of the fixed block 8 is fixedly connected to a smooth rod 9, and the surface of the smooth rod 9 is slidably connected to a second fixed seat 10.

[0035] Specifically, the support structure 4 includes a side support rod 11 fixedly connected to the surface of the first fixed seat 7 and the second fixed seat 10. The side support rod 11 is arranged longitudinally, and a first guide groove 12 is opened on the surface of the side support rod 11. There are two side support rods 11.

[0036] Specifically, a positioning shaft 13 is fixedly connected to the bottom end of the side support rod 11, and a sliding rod 14 is provided at the top end of the side support rod 11. The sliding rod 14 is slidably connected to the inner wall of the first guide groove 12.

[0037] Specifically, a scissor-type isolation frame 15 is provided in the middle of the two side support rods 11. The bottom ends of both sides of the scissor-type isolation frame 15 are rotatably connected to the positioning shafts 13 at the bottom of the side support rods 11, and the top ends of both sides of the scissor-type isolation frame 15 are rotatably connected to the sliding rods 14 inside the side support rods 11.

[0038] Specifically, a central positioning rod 16 is fixedly connected to the bottom of the hinge at the end of the scissor-type isolation frame 15. A second guide groove 17 is provided on the surface of the central positioning rod 16. The hinge shaft at the top of the scissor-type isolation frame 15 is slidably connected to the inner wall of the second guide groove 17. A yarn guide frame 18 is fixedly connected to the middle of the positioning shaft 13.

[0039] With the above structural design, when the device is in use, the machine body support frame 1 and the whole device are fixed at the yarn guide position of the spinning machine by fixing the ear plate 2. After completion, the yarn is passed through the yarn guide frame 18 in sequence and fixed at the spinning position. When spinning, the yarn passes through the middle of the yarn guide frame 18, thus realizing the guidance of the yarn.

[0040] When the yarn needs adjustment, the servo motor 5 is activated to drive the threaded rod 6 to rotate. As the threaded rod 6 rotates, it drives the side support rod 11 to slide to both sides through the first fixed seat 7. As the side support rod 11 slides to both sides, its bottom end slides on the surface of the smooth rod 9 through the second fixed seat 10. While the side support rod 11 moves to both sides, the bottom ends of both sides of the scissor-type isolation frame 15 rotate around the positioning shaft 13. At the same time, the top of the scissor-type isolation frame 15 rotates around the sliding rod 14 and pulls the sliding rod 14 to slide downward on the inner wall of the first guide groove 12. As the top of the scissor-type isolation frame 15 descends, the hinge rod at the junction of its top end slides downward on the inner wall of the second guide groove 17. At this time, the spacing of the scissor-type isolation frames 15 is stretched, so that the scissor-type isolation frames 15 can move away from each other synchronously. This can achieve rapid adjustment of the yarn spacing. Conversely, the yarn guide frame 18 can move closer to each other and cause the yarn to shrink.
