Description

Technical Field

[0001] This utility model relates to the field of yarn guiding technology for ring spinning machines, specifically a yarn guiding device for ring spinning machines that prevents yarn from falling off and being scratched. Background Technology

[0002] Utility model application CN202123406221.3 discloses a yarn guiding device for a spinning frame in cotton yarn production. By setting up a tension adjusting device, it controls the tension during yarn transmission, ensuring the yarn remains taut throughout the transmission process and helping to prevent the yarn from tangling with the equipment.

[0003] The aforementioned device guides the yarn using guide rollers. However, in actual use, the yarn and guide rollers are not perfectly perpendicular. When the yarn experiences changes in force during movement, it is easy for the yarn to fall off the guide rollers, causing scratches and resulting in uneven yarn processing, which reduces the processing effect. Utility Model Content

[0004] The purpose of this invention is to solve the above-mentioned problems by designing a yarn guiding device for a spinning machine that prevents yarn from falling off and getting scratched.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A yarn guiding device for a spinning machine that prevents yarn slippage and scratching, comprising:

[0007] Base;

[0008] A fixed frame is fixedly installed on a base. A transverse support is slidably connected inside the fixed frame. Multiple sliding parts are slidably connected to the transverse support. The transverse support is used to drive the sliding parts to rise and fall. A locking bolt is threaded onto the sliding part. The locking bolt passes through the sliding part and contacts the transverse support.

[0009] A yarn guide assembly is used to guide the yarn. The yarn guide assembly is disposed on a slider so that the yarn guide assembly moves with the slider.

[0010] The yarn passes through the yarn guide assembly, which guides the yarn and reduces its friction during the process. This allows the yarn to rotate and is flexible, preventing it from falling off the assembly and causing scratches. This ensures even yarn processing and improves the overall processing effect. The sliding component allows the yarn guide assembly to slide along the transverse support, adjusting its left and right positions.

[0011] Furthermore, the yarn guiding assembly includes a lower roller frame, the lower roller is mounted on a sliding member, the lower roller frame is rotatably connected to the sliding member via a rotating shaft, a lower guide wheel is rotatably connected to the lower roller frame, a support member is connected to the bottom of the transverse support member, a power push rod is installed on the base, and the drive end of the power push rod is connected to the bottom of the support member.

[0012] The height of the lower guide wheel can be finely adjusted by driving the transverse support and the lower roller frame with a power push rod, keeping the yarn taut and preventing it from getting tangled with the equipment, thus improving product quality. The yarn is guided by the lower guide wheel, and the rotation of the lower guide wheel during the yarn guiding process reduces the friction with the yarn. When the yarn movement changes, the lower roller frame and the lower guide wheel can rotate through the rotating shaft, which can flexibly guide the yarn and prevent the yarn from falling off the lower guide wheel and causing scratches, resulting in uniform yarn processing and improved processing effect.

[0013] Furthermore, the yarn guiding assembly also includes an upper roller frame, on which an upper guide wheel is rotatably connected. A guide side plate is installed on the side wall of the lower roller frame, and a guide groove is provided on the guide side plate. A guide slider is slidably connected in the guide groove. The side wall of the lower roller frame is fixedly connected to the guide slider. A telescopic spring is provided in the guide groove, with one end of the telescopic spring connected to the guide groove and the other end of the telescopic spring connected to the guide slider.

[0014] The yarn passes between the upper and lower guide rollers to prevent it from falling off between them, thus avoiding yarn scratches, ensuring uniform yarn processing, and improving processing results.

[0015] Furthermore, the yarn guide assembly also includes an upper top plate, which is located above the fixed frame. Lifting cylinders are installed on both sides of the top of the fixed frame. The driving end of the lifting cylinder is fixedly connected to the upper top plate. The fixed frame and the upper top plate are provided with transverse through grooves. A connecting rod is installed on the top of the upper roller frame. The top end of the connecting rod extends out of the transverse through groove, and a limit plate is connected to the top end of the connecting rod.

[0016] It can raise all the upper roller frames at the same time, creating a gap between the upper and lower guide rollers, which makes it easier to place the yarn on the lower guide rollers. It eliminates the need to manually lift the upper guide rollers one by one, reducing labor intensity and improving work efficiency.

[0017] Furthermore, the inner walls on both sides of the fixing frame are provided with vertical guide grooves, and the two ends of the horizontal support extend into the vertical guide grooves.

[0018] Furthermore, rubber pads are provided inside the upper guide wheel and the lower guide wheel.

[0019] Rubber pads are used to protect the yarn, preventing it from fraying or getting damaged by friction. Attached Figure Description

Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] This utility model provides, for example Figure 1-5The yarn guiding device for a spinning machine shown includes:

[0029] Base 1;

[0030] The fixed frame 2 is fixedly installed on the base 1. A transverse support 3 is slidably connected inside the fixed frame 2. Multiple sliding parts 4 are slidably connected on the transverse support 3. The transverse support 3 is used to drive the sliding parts 4 to rise and fall. A locking bolt 5 is threaded on the sliding part 4. The locking bolt 5 passes through the sliding part 4 and contacts the transverse support 3.

[0031] The yarn guide assembly 6 is used to guide the yarn. The yarn guide assembly 6 is disposed on the slider 4 so that the yarn guide assembly 6 moves with the slider 4.

[0032] The base 1 is bolted between the front roller output roller and the yarn tube or winding device. The yarn passes through the yarn guide assembly 6, which guides the yarn and reduces its friction during the yarn guiding process. This allows the yarn to rotate and can guide it flexibly, preventing it from falling off the yarn guide assembly 6 and causing it to get scratched. This ensures uniform yarn processing and improves the processing effect of the spinning machine. The sliding part 4 can drive the yarn guide assembly 6 to slide along the transverse support 3, and can adjust the left and right position of the yarn guide assembly 6. The sliding part 4 is fixed by tightening the locking bolt 5.

[0033] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 3 Included with instruction manual Figure 4 The yarn guide assembly 6 includes a lower roller frame 7, which is mounted on the sliding member 4. The lower roller frame 7 is rotatably connected to the sliding member 4 via a rotating shaft 8. A lower guide wheel 9 is rotatably connected to the lower roller frame 7. A support member 10 is connected to the bottom of the transverse support member 3. A power push rod 11 is installed on the base 1. The drive end of the power push rod 11 is connected to the bottom of the support member 10.

[0034] The yarn passes through the lower guide wheel 9, activating the power push rod 11. The drive end of the power push rod 11 drives the support component 10, which in turn drives the transverse support component 3 to rise and fall. The transverse support component 3, in turn, drives the sliding component 4 and the lower guide wheel 9 to rise and fall. This allows for fine-tuning of the height of the lower guide wheel 9, keeping the yarn taut and preventing it from tangling with the equipment, thus improving product quality. The yarn is guided by the lower guide wheel 9. During the yarn guiding process, the rotation of the lower guide wheel 9 reduces the friction with the yarn. When the yarn movement changes, the lower roller frame 7 and the lower guide wheel 9 can rotate via the rotating shaft 8, allowing for flexible yarn guiding and preventing the yarn from falling off the lower guide wheel 9 and causing scratches. This ensures uniform yarn processing and improves the processing effect.

[0035] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 2 The yarn guide assembly 6 also includes an upper roller frame 12, on which an upper guide wheel 13 is rotatably connected. A guide side plate 14 is installed on the side wall of the lower roller frame 7. A guide groove 15 is provided on the guide side plate 14. A guide slider 16 is slidably connected in the guide groove 15. The side wall of the lower roller frame 7 is fixedly connected to the guide slider 16. A telescopic spring 17 is provided in the guide groove 15. One end of the telescopic spring 17 is connected to the guide groove 15, and the other end of the telescopic spring 17 is connected to the guide slider 16.

[0036] The upper guide wheel 13 contacts the lower guide wheel 9, and the yarn passes between the upper guide wheel 13 and the lower guide wheel 9. The upper roller frame 12 can be raised and lowered along the guide groove 15 via the guide slider 16. After the upper roller frame 12 is raised, there is a gap between the upper guide wheel 13 and the lower guide wheel 9, which makes it easy to place the yarn on the lower guide wheel 9. Under the elastic force of the telescopic spring 17, the guide slider 16 is lowered along the guide groove 15, so that the upper guide wheel 13 and the lower guide wheel 9 are in close contact, preventing the yarn from falling out between the upper guide wheel 13 and the lower guide wheel 9, avoiding yarn scratches, making the yarn processing uniform, and improving the processing effect.

[0037] Refer to the instruction manual appendix Figure 3 Instruction manual attached Figure 4 Included with instruction manual Figure 5 The yarn guide assembly 6 also includes an upper top plate 18, which is located above the fixed frame 2. Lifting cylinders 19 are installed on both sides of the top of the fixed frame 2. The driving end of the lifting cylinder 19 is fixedly connected to the upper top plate 18. The fixed frame 2 and the upper top plate 18 are provided with transverse through grooves 20. A connecting rod 21 is installed on the top of the upper roller frame 12. The top end of the connecting rod 21 extends out of the transverse through groove 20. The top end of the connecting rod 21 is connected to a limit plate 22.

[0038] When the yarn is placed between the upper guide wheel 13 and the lower guide wheel 9, the lifting cylinder 19 starts to work. The drive end of the lifting cylinder 19 drives the upper top plate 18 to rise. The upper top plate 18 rises and contacts the limiting plate 22, causing it to rise synchronously. The limiting plate 22 drives the upper roller frame 12 to rise through the connecting rod 21. The upper roller frame 12 drives the guide slider 16 to rise along the guide groove 15. The guide slider 16 applies pressure to the telescopic spring 17. The telescopic spring 17 deforms and contracts under pressure, which can simultaneously raise all of the upper roller frames 12. A gap is created between the upper guide wheel 13 and the lower guide wheel 9, which facilitates the placement of yarn onto the lower guide wheel 9. This eliminates the need for manual lifting of the upper guide wheels 13 one by one, reducing labor intensity and improving work efficiency. After the yarn is completely placed between the upper guide wheel 13 and the lower guide wheel 9, the lifting cylinder 19 and the upper top plate 18 are reset. Under the elastic force of the telescopic spring 17, the guide slider 16 descends along the guide groove 15, ensuring close contact between the upper guide wheel 13 and the lower guide wheel 9, and preventing the yarn from falling out between the upper guide wheel 13 and the lower guide wheel 9.

[0039] Refer to the instruction manual appendix Figure 3 Included with instruction manual Figure 4 The inner walls on both sides of the fixed frame 2 are provided with vertical guide grooves 23, and the two ends of the horizontal support 3 extend into the vertical guide grooves 23.

[0040] The horizontal support 3 moves up and down along the vertical guide groove 23, which guides the horizontal support 3 and prevents the horizontal support 3 from shifting position.

[0041] Refer to the instruction manual appendix Figure 1 Rubber pads 24 are provided inside the upper guide wheel and the lower guide wheel 9.

[0042] The yarn comes into contact with the rubber pad 24, which protects the yarn from friction and prevents it from getting fuzzy or damaged.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
