Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, specifically to a device for slowing down the slippage of silk filaments. Background Technology

[0002] In the textile industry, the production of worsted wool and silk filament yarn is a highly precise and demanding process. Silk filament occupies an important position in the high-end textile market due to its unique luster, softness and strength. However, the inherent characteristics of silk filament fibers, such as less crimp, poor cohesion and relatively smooth surface, bring challenges to its processing.

[0003] A search revealed a Chinese patent with publication number CN215251451U, which discloses a feeding adjustment mechanism for a spinning frame, including a control cabinet and a spinning frame body. A fixed base is bolted to the top of the control cabinet, and the bottom of both sides of the spinning frame body are bolted to the opposite side of the control cabinet. An adjustment mechanism is installed inside the fixed base, and a through groove for cooperation with the adjustment mechanism is opened at the bottom of the opposite side of the fixed base. A support plate is bolted to the outer side of the back of the fixed base. This invention, through the cooperation of a second rack plate, a moving plate, a moving rod, and a guide wheel, allows for accurate adjustment of the yarn tension during processing. This avoids yarn breakage or scattering caused by a fixed feeding mechanism, thus facilitating high-quality yarn processing. High-quality textile yarn also significantly improves the economic benefits of textile enterprises, solving the problem that traditional spinning frame feeding mechanisms lack adjustment functions.

[0004] However, in actual use, the above-mentioned feeding mechanism cannot slow down the rapid slippage of the yarn during feeding. Due to the inherent characteristics of silk filament fibers, such as less crimp, poor cohesion and relatively smooth surface, the fibers tend to slip and accumulate together when the fine yarn is fed into the silk filament during the spinning process, thus forming defects, causing breakage and affecting spinning efficiency.

[0005] Therefore, this utility model provides a device to slow down the slippage of silk filaments. Utility Model Content

[0011] Preferably, two first guide wheels are provided below the conduit, and a first rotating shaft is fixedly connected to the middle of the first guide wheel. The first rotating shaft is rotatably connected to the U-shaped frame.

[0012] Preferably, the U-shaped frame has sliding grooves on both side walls, and sliders are slidably connected to both ends of the sliding grooves. A bidirectional lead screw is rotatably connected to the U-shaped frame at an adjacent position to the sliding groove. Two sliders are located at both ends of the bidirectional lead screw and are threadedly connected to the bidirectional lead screw. One end of the bidirectional lead screw extends to the outside of the U-shaped frame and is fixedly connected to a synchronous pulley. The two synchronous pulleys are driven by a synchronous belt.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention utilizes a base, top cover, and deceleration ring design to slow down the rapid slippage of silk filaments. During operation, the deceleration ring is fitted onto the top cover, which is then secured to the base. The base is then secured to the top of the bobbin. The ends of the silk filaments on the bobbin are pulled, allowing them to pass through the gap between the deceleration ring and the top cover, and finally through the guide tube. During feeding, the deceleration ring creates resistance to the silk filaments, thus slowing their rapid slippage. Furthermore, a motor drives two bidirectional lead screws to rotate, causing two tension wheels to move synchronously in opposite directions, increasing the tension of the silk filaments. This increased tension enhances the stability of the silk filaments during processing, reducing slippage caused by external forces. Higher tension also makes the silk fibers more taut, preventing relative slippage. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Please see Figure 1-7 This utility model provides a technical solution: a device for slowing down the slippage of silk filaments, including a U-shaped frame 1, with support arms 2 fixedly connected to both ends of the top of the U-shaped frame 1, a limiting plate 3 fixedly connected to the top of the two support arms 2, a plug-in post 4 fixedly connected to the top of the limiting plate 3, a wire tube 5 fixedly connected to the middle of the plug-in post 4, a bobbin 6 sleeved on the outer wall of the plug-in post 4, silk filaments 7 wound around the outer wall of the bobbin 6, a base 8 snapped onto the top of the bobbin 6, and a top cover snapped onto the top of the base 8. 9. A deceleration ring 10 is fitted on one end of the outer wall of the top cover 9. The wire conduit 5 passes through the limiting plate 3, the plug post 4, the base 8 and the top cover 9. A first limiting flange 11 is provided on one end of the outer wall of the base 8, and a second limiting flange 12 is provided on one end of the outer wall of the top cover 9. The deceleration ring 10 is located between the first limiting flange 11 and the second limiting flange 12. The inner diameter of the deceleration ring 10 is larger than the outer diameter of the top cover 9. The diameters of the first limiting flange 11 and the second limiting flange 12 are both larger than the inner diameter of the deceleration ring 10.

[0027] In this embodiment, the design of the base 8, top cover 9, and deceleration ring 10 is used to slow down the rapid slippage of the silk filament 7. During operation, the U-shaped frame 1 is first fixed to the feed port of the spinning machine, then the bobbin 6 is sleeved on the insertion post 4, and then the deceleration ring 10 is sleeved on the top cover 9. At this time, the deceleration ring 10 is located between the first limiting flange 11 and the second limiting flange 12, and the top cover 9 is snapped onto the base 8. At the same time, the base 8 is snapped onto the top of the bobbin 6. At this time, the top of the guide tube 5 will pass through the base 8 and the top cover. 9 extends to the top cover 9, then pulls the end of the silk filament 7 wound on the cylinder and lets it pass through the gap between the deceleration tube and the top cover 9, and finally through the guide tube 5. In this way, when feeding, the deceleration ring 10 will generate a certain resistance to the silk filament 7, thereby slowing down the rapid slippage of the silk filament 7 during feeding. The diameter of the inner wall of the deceleration ring 10 is larger than the diameter of the outer wall of the top cover 9, so the silk filament 7 will not be torn off during feeding due to the deceleration ring 10 and the top cover 9 being too tightly locked.

[0028] like Figure 4 and Figure 5 As shown, the top of the base 8 is provided with a slot 13, which is engaged with the top cover 9. The middle of the base 8 is provided with a first sleeve 14, and the top of the inner wall of the top cover 9 is provided with a second sleeve 15, which is engaged with the first sleeve 14.

[0029] In this embodiment, the design of the slot 13 allows the base 8 and the top cover 9 to be smoothly snapped together. The design of the first sleeve 14 and the second sleeve 15 allows the connection between the base 8 and the top cover 9 to be tighter. The wire tube 5 passes through the inside of the first sleeve 14 and the second sleeve 15.

[0030] like Figure 4 As shown, the bottom of the base 8 is provided with multiple locking blocks 16, which are distributed in a stepped manner and are engaged with the tube 6.

[0031] In this embodiment, the design of the locking block 16 allows the base 8 to be smoothly engaged with the tube 6. By setting multiple locking blocks 16 in a stepped design, it is easy for the base 8 to be engaged with tubes 6 of different inner diameters.

[0032] like Figure 6 and Figure 7 As shown, two first guide wheels 17 are provided below the conduit 5. A first rotating shaft 18 is fixedly connected to the middle of the first guide wheel 17. The first rotating shaft 18 is rotatably connected to the U-shaped frame 1.

[0033] In this embodiment, the design of the first guide wheel 17 allows the silk filament 7 to change its direction of travel, thereby smoothly feeding it into the spinning machine. The outer wall of the first guide wheel 17 has a groove in the middle, which can prevent the silk filament 7 from falling off the first guide wheel 17.

[0034] like Figure 6 and Figure 7 As shown, the U-shaped frame 1 has sliding grooves 19 on both side walls, and sliders 20 are slidably connected to both ends of the sliding grooves 19. A bidirectional lead screw 21 is rotatably connected to the U-shaped frame 1 at a position adjacent to the sliding grooves 19. Two sliders 20 are located at both ends of the bidirectional lead screw 21 and are threadedly connected to the bidirectional lead screw 21. One end of the bidirectional lead screw 21 extends to the outside of the U-shaped frame 1 and is fixedly connected to a synchronous pulley 22. The two synchronous pulleys 22 are driven by a synchronous belt 23. A motor 24 is fixedly connected to one end of the side wall of the U-shaped frame 1, and the output end of the motor 24 is fixedly connected to the bidirectional lead screw 21. Inside the U-shaped frame 1, below the first guide wheel 17, there are two tension wheels 25. The two tension wheels 25 are located at both ends of the bidirectional lead screw 21. A connecting shaft 26 is fixedly connected to the middle of the tension wheels 25, and the two ends of the connecting shaft 26 are rotatably connected to the two sliders 20.

[0035] In this embodiment, the design of the synchronous pulley 22 and the synchronous belt 23 enables the two bidirectional lead screws 21 to rotate synchronously. The motor 24 drives one of the bidirectional lead screws 21 to rotate, thereby driving the other bidirectional lead screw 21 to rotate synchronously. When the bidirectional lead screw 21 rotates, it drives the two sliders 20 to move synchronously in opposite directions, thereby driving the connecting shaft 26 to move synchronously in opposite directions, and then driving the two tension wheels 25 to move synchronously in opposite directions. By adjusting the distance between the two tension wheels 25, the tension of the silk filament 7 is increased. The increase in tension helps to enhance the stability of the silk filament 7 during the processing and reduce the slippage caused by external forces. Higher tension makes the silk filament 7 fibers tighter and less prone to relative slippage.

[0036] like Figure 6 and Figure 7 As shown, two second guide wheels 27 are provided at the bottom of the inner wall of the U-shaped frame 1. The two second guide wheels 27 are located directly below the two first guide wheels 17. A second rotating shaft 28 is fixedly connected to the middle of the second guide wheels 27. The second rotating shaft 28 is rotatably connected to the U-shaped frame 1. A wire hole 29 is provided at the bottom of the U-shaped frame 1 below the two second guide wheels 27.

[0037] In this embodiment, the second guide wheel 27 is designed to guide the silk filament 7 after the tension is increased, and the through hole 29 is designed to allow the silk filament 7 to pass through the U-shaped frame 1, thereby facilitating subsequent feeding.

[0038] Working Principle: In use, first fix the U-shaped frame 1 to the feed inlet of the spinning machine. Then, attach the bobbin 6 to the insert post 4. Next, place the deceleration ring 10 on the top cover 9, positioned between the first limiting flange 11 and the second limiting flange 12. Secure the top cover 9 to the base 8, and simultaneously attach the base 8 to the top of the bobbin 6. The top of the guide tube 5 will then pass through the base 8 and the top cover 9, extending above the top cover 9. Next, pull the end of the silk filament 7 wound on the bobbin, allowing it to pass through the gap between the deceleration ring and the top cover 9, and finally through the guide tube 5. During feeding, the deceleration ring 10 will generate resistance against the silk filament 7, thus slowing its rapid slippage. The inner diameter of the deceleration ring 10 is larger than the outer diameter of the top cover 9, preventing the silk filament 7 from being too tightly secured between the deceleration ring 10 and the top cover 9 during feeding. When torn, the silk filament 7 passes through the guide tube 5 and enters between the two first guide rollers. Then, the silk filament 7 is wrapped around the two tension rollers 25, and the end of the silk filament 7 passes between the two second guide rollers 27. Finally, it passes through the thread hole 29 and is pulled into the spinning machine. During the feeding process, the motor 24 can be turned on to drive the two bidirectional lead screws 21 to rotate. When the bidirectional lead screws 21 rotate, they can drive the two sliders 20 to move synchronously in opposite directions, thereby driving the connecting shaft 26 to move synchronously in opposite directions, and then driving the two tension rollers 25 to move synchronously in opposite directions. By adjusting the distance between the two tension rollers 25, the tension of the silk filament 7 can be increased. The increase in tension helps to enhance the stability of the silk filament 7 during processing and reduce slippage caused by external forces. Higher tension makes the silk filament 7 fibers tighter and less prone to relative slippage.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes and modifications can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
