Description

Technical Field

[0001] This utility model relates to the field of false twist device manufacturing technology, and more specifically to a quick installation structure for a false twist device belt guide wheel. Background Technology

[0002] Ring spinning technology is currently the most widely used spinning technology both domestically and internationally. Twisting is an important step in short fiber spinning. In this process, the yarn output from the front roller passes through the guide hook, through the traveler riding on the edge of the ring, and is tightly wrapped around the bobbin of the spindle. When the spindle rotates, due to the tension of the yarn, the traveler rotates along the ring, and the yarn thus acquires twist.

[0003] According to the utility model patent application filed earlier by the present inventor, with publication number CN222744482U and publication date of 2025-04-11, an anti-winding mechanism for a false-twist spinning device is disclosed. The mechanism includes a protective housing and a yarn guide transmission mechanism disposed inside the protective housing. The protective housing has a yarn wheel mounting seat, and also includes a yarn guide wheel and a dustproof rubber ring. The yarn guide wheel is rotatably connected to the yarn wheel mounting seat and has a mounting groove. The dustproof rubber ring includes a connecting part and a dustproof part. A limiting groove is formed inside the connecting part, and the connecting part abuts against the yarn guide wheel through the limiting groove. The dustproof rubber ring is connected to the mounting groove through the connecting part, and the dustproof part fits against the outer wall of the yarn wheel mounting seat. Its main technical effect is that the connecting part of the dustproof rubber ring abuts against the yarn guide wheel through the limiting groove, and the dustproof part of the dustproof rubber ring can fit against the outer wall of the yarn wheel mounting seat, thereby sealing the gap between the yarn guide wheel and the yarn wheel mounting seat and preventing loose yarn from entering the interior of the yarn guide wheel.

[0004] In the aforementioned false-twist spinning device, the anti-winding mechanism causes yarn to get tangled in the belt guide pulley during the spinning process, requiring regular cleaning. Since the belt guide pulley is connected to the transmission gear via bolts, the cleaning process causes the belt guide pulley to rotate, which in turn causes the yarn guide wheel to rotate via the transmission gear, resulting in inconvenient maintenance. To address this, a quick-installation structure for the belt guide pulley of the false-twist device is proposed, aiming to solve the problem of inconvenient maintenance caused by the simultaneous rotation of the yarn guide wheel during cleaning of the belt guide pulley in the existing technology.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] Please see Figure 1 — Figure 5A quick-installation structure for a false twist device belt guide wheel includes a mounting plate 1, on which a yarn guide wheel 2 is mounted. The mounting plate 1 also has a connecting screw 3 and a reverse-threaded screw 4, which are connected in a transmission manner. An arc-shaped rubber ring 5 is fixedly mounted on the yarn guide wheel 2, and the arc-shaped rubber ring 5 has an arc-shaped surface 51 on its peripheral wall. The connecting screw 3 is connected to the yarn guide wheel 2. A belt guide wheel 6 is connected to the reverse-threaded screw 4, and a positioning screw hole 61 is provided on the belt guide wheel 6. A fastening screw 62 is connected to the positioning screw hole 61. The belt guide wheel 6 is connected to the reverse-threaded screw 4 via the fastening screw 62. A rubber cup 7 is connected to the reverse-threaded screw 4, and the rubber cup 7 is positioned between the belt guide wheel 6 and the mounting plate 1.

[0024] As an embodiment provided by this utility model, such as Figure 2 As shown, a second positioning hole 11 is provided on the outer wall of the mounting plate 1. A bearing 10 is installed in the second positioning hole 11. The reverse-threaded screw 4 is rotatably connected to the second positioning hole 11 through the bearing 10. The belt guide pulley 6 is connected to the reverse-threaded screw 4. Specifically, a positioning screw hole 61 is provided on the circumferential outer wall of the belt guide pulley 6. A fastening screw 62 is threaded inside the positioning screw hole 61. The belt guide pulley 6 is fastened to the reverse-threaded screw 4 through the fastening screw 62 in the positioning screw hole 61, thereby achieving coaxial rotation. The belt guide pulley 6 is connected to the mounting plate 1 with a reverse-threaded screw 4, which can prevent the belt guide pulley 6 from loosening during rotation.

[0025] As a further embodiment provided by this utility model, such as Figure 2 As shown, a housing component 8 is fixedly installed on the mounting plate 1. A first positioning hole 81 is provided on the housing component 8. A bearing component 10 is provided in the first positioning hole 81. The connecting screw 3 is rotatably connected to the first positioning hole 81 through the bearing component 10. A first gear 31 is fixedly installed on the connecting screw 3. A second gear 41 is fixedly installed on the reverse thread screw 4. The first gear 31 and the second gear 41 mesh with each other, thereby ensuring that the reverse thread screw 4 and the connecting screw 3 maintain a transmission connection, so that when the belt guide pulley 6 keeps rotating, it synchronously drives the guide yarn wheel 2 on the connecting screw 3 to keep rotating.

[0026] like Figure 5 As shown, the first gear 31 is engaged with the end of the connecting screw 3, and the second gear 42 is engaged with the end of the reverse thread screw 4 to ensure that the first gear 31 can mesh with the second gear 42.

[0027] An installation groove is provided on the outer wall of the guide roller 2, and an arc-shaped rubber ring 5 is fixedly installed in the installation groove. Specifically, an arc-shaped surface 51 is provided on the outer peripheral wall of the arc-shaped rubber ring 5. By abutting the yarn with the arc-shaped surface 51, the force on the yarn during false twisting can be reduced, preventing yarn breakage and yarn breakage, and improving spinning efficiency.

[0028] A rubber cup 7 is connected to the reverse thread screw 4. The rubber cup 7 is located between the belt guide pulley 6 and the mounting plate 1. The rubber cup 7 allows the top of the belt guide pulley 6 to be located inside the rubber cup 7. By covering the top of the belt guide pulley 6 to a certain extent, the amount of yarn entering the top of the belt guide pulley 6 is reduced, which plays a certain role in preventing tangling.

[0029] Furthermore, such as Figure 4 and Figure 3 As shown, the rubber cup 7 includes an arc-shaped portion 71 and a straight cylindrical portion 72. A partition is provided between the arc-shaped portion 71 and the straight cylindrical portion 72. A circular hole is provided on the partition for the reverse-threaded screw 4 to pass through. The inner diameter of the straight cylindrical portion 72 is adapted to the outer diameter of the second positioning hole 11, so that the rubber cup 7 can cover the second positioning hole 11 through the straight cylindrical portion 72, preventing the yarn from winding onto the reverse-threaded screw 4 from between the rubber cup 7 and the second positioning hole 11. The opening of the arc-shaped portion 71 is oriented towards the belt guide wheel 6 and can accommodate a portion of the belt guide wheel 6. The bottom diameter of the arc-shaped portion 71 is larger than the outer diameter of the belt guide wheel 6. The outer arc surface of the arc-shaped portion 71 can guide the floating yarn and prevent the floating yarn from entering the top of the belt guide wheel 6.

[0030] As a further embodiment provided by this utility model, such as Figure 1 As shown, it also includes a connecting ring 9, which is rotatably connected to the mounting plate 1. An elastic unit is provided between the connecting ring 9 and the mounting plate 1. Specifically, the elastic unit is a torque spring. The torque spring can drive the mounting plate 1 to rotate to one side, so that the mounting plate 1 abuts against the abutting block on the connecting ring 9. The mounting plate 1 can be connected to the frame of the spinning equipment through the connecting ring 9. A limit screw is connected to the connecting ring 9. The position of the connecting ring 9 on the equipment frame can be quickly adjusted by adjusting the limit screw.

[0031] This utility model features an arc-shaped rubber ring 5 on the guide wheel 2 with an arc-shaped surface 51 on its peripheral wall. The arc-shaped surface 51 abuts against the yarn, reducing the force applied to the yarn, preventing yarn breakage, and improving twisting efficiency. The belt guide wheel 6 is fastened to the reverse thread screw 4 through the positioning screw hole 61 and the fastening screw 62. When disassembling and assembling the belt guide wheel 6 for maintenance, it can be disassembled by holding the belt guide wheel 6 and using a screwdriver. When inspecting the yarn inside the belt guide wheel 6, it can prevent the guide wheel 2 from rotating, thus facilitating maintenance. At the same time, the rubber cup 7 set between the belt guide wheel 6 and the mounting plate 1 can cover part of the belt guide wheel 6 to prevent the yarn from getting tangled in the belt guide wheel 6.

[0032] Preferably, the belt guide wheel 6 is made of metal and has anti-slip texture on its peripheral wall. When disassembly is required, the operator can disassemble the belt guide wheel 6 by holding it and using a screwdriver or wrench to unscrew the fastening screw 62, which makes it easier to clean the yarn wrapped on the reverse thread screw 4.
