Description

Technical Field

[0001] This utility model relates to the field of yarn guides, specifically a differential polyester yarn anti-deviation precision yarn guide structure. Background Technology

[0002] Yarn guides are a key component in textile machinery, mainly used to guide yarns along a specific path, ensuring that the yarns maintain appropriate tension, position, and orientation during processing. The anti-deviation precision yarn guide for differentiated polyester yarns is a device specifically designed for high-precision textile processing. It is mainly used to prevent polyester yarns from shifting position during high-speed operation, ensuring the stability and consistency of the yarn path.

[0003] In the existing technology, existing yarn guides need to apply appropriate tension to the yarn during the yarn guiding process. Since different types of yarn require different levels of tension, the existing yarn guide structure is not convenient for adjusting the yarn tension, which reduces the applicability of the yarn guide. At the same time, due to different installation positions of the yarn bobbins, the yarn may enter the yarn guide at an excessively steep angle, damaging the yarn. The existing yarn guide structure is not convenient for adjusting the position of the yarn guide to avoid damaging the yarn, thus reducing the quality of the fabric. Utility Model Content

[0004] To overcome the shortcomings of existing technologies and solve the problems of inconvenience in adjusting yarn tension and inconvenience in adjusting the position of the yarn guide to avoid damaging the yarn, this utility model proposes a differentiated polyester yarn anti-deviation precision yarn guide structure.

[0005] The technical solution adopted by this utility model to solve its technical problem is: the differential polyester yarn anti-deviation precision yarn guide structure of this utility model includes a yarn guide plate, a frame plate fixedly connected to the bottom of the yarn guide plate, an adjustable tension component rotatably connected to the middle of the top of the frame plate, a moving platform fixedly connected to the bottom of the frame plate, and an adjustment component fixedly connected to the middle of the bottom of the moving platform.

[0006] The adjustable tension assembly includes a threaded rod rotatably connected to the center of the top of the frame plate, a transmission rod A fixedly connected to the top of the threaded rod, a servo motor A splinedly connected to the top of the transmission rod A, a threaded cylinder A threadedly connected to the surface of the threaded rod, a connecting plate fixedly connected to the bottom of the threaded cylinder A, and a pulley rotatably connected to one side of the connecting plate.

[0007] The adjustment assembly includes a B-threaded cylinder fixedly connected to the center of the bottom of the mobile platform. A lead screw is threaded onto the inner surface of the B-threaded cylinder. A B-transmission rod is fixedly connected to one end of the lead screw, and a B-servo motor is splined to one end of the B-transmission rod.

[0008] Preferably, sliding plates are fixedly connected to both sides of the threaded cylinder A, and frame plates are slidably connected to the surface of the sliding plates.

[0009] Preferably, a slider is fixedly connected to the bottom edge of the mobile platform, a slide rail is slidably connected to the bottom of the slider, and a base plate is fixedly connected to the bottom of the slide rail.

[0010] Preferably, the two ends of the slide rail are fixedly connected to limit plates, the surface of the limit plates is rotatably connected to lead screws, and the bottom of the limit plates is fixedly connected to a base plate.

[0011] Preferably, the surface of the A servo motor is fixedly connected to the A motor box, and the bottom of the A motor box is fixedly connected to the frame plate.

[0012] Preferably, a B motor box is fixedly connected to the surface of the B servo motor, and a base plate is fixedly connected to the bottom of the B motor box.

[0013] The advantages of this utility model are:

[0014] 1. This utility model, through the structural design of the adjustable tension component, allows the yarn to pass through the yarn guide plate when using this yarn guide structure. Then, the A servo motor is connected to the power supply and powered on, causing the A transmission rod to drive the threaded rod to rotate. The threaded rod pushes the A threaded cylinder down until the pulley squeezes the yarn. Friction force imparts tension to the yarn during its movement. At the same time, the rotational connection between the pulley and the connecting plate can prevent the yarn from getting stuck during the squeezing process. By controlling the force of the pulley squeezing the yarn, the amount of tension imparted to the yarn can be adjusted, thus improving the applicability of the yarn guide structure.

[0015] 2. By adjusting the structural settings of the components, before using the yarn guide structure, the B servo motor is powered on, causing the B transmission rod to drive the lead screw to rotate. The thread on the lead screw pushes the B threaded cylinder and the moving platform to move horizontally along the lead screw, thereby changing the relative position of the yarn guide plate and the yarn cylinder. This allows the yarn guide structure to adjust the position of the yarn guide to avoid damaging the yarn and improve the fabric quality. Attached Figure Description

[0022] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figures 1-4 As shown, a differential polyester yarn anti-deviation precision yarn guide structure includes a yarn guide plate 1, a frame plate 2 fixedly connected to the bottom of the yarn guide plate 1, an adjustable tension component 3 rotatably connected to the middle of the top of the frame plate 2, a moving platform 4 fixedly connected to the bottom of the frame plate 2, and an adjustment component 5 fixedly connected to the middle of the bottom of the moving platform 4.

[0024] The adjustable tension assembly 3 includes a threaded rod 301 rotatably connected to the center of the top of the frame plate 2. A transmission rod 302 is fixedly connected to the top of the threaded rod 301. A servo motor 303 is splinedly connected to the top of the transmission rod 302. A threaded cylinder 304 is threadedly connected to the surface of the threaded rod 301. A connecting plate 305 is fixedly connected to the bottom of the threaded cylinder 304. A pulley 306 is rotatably connected to one side of the connecting plate 305.

[0025] The adjustment assembly 5 includes a B threaded cylinder 501 fixedly connected to the middle of the bottom of the mobile platform 4. A lead screw 502 is threadedly connected to the inner surface of the B threaded cylinder 501. A B transmission rod 503 is fixedly connected to one end of the lead screw 502. A B servo motor 504 is splinedly connected to one end of the B transmission rod 503.

[0026] During operation, thanks to the adjustable tension component 3, when using this yarn guide structure, the yarn passes through the yarn guide plate 1. Then, the A servo motor 303 is connected to the power supply, causing the A transmission rod 302 to drive the threaded rod 301 to rotate. The threaded rod pushes the A threaded cylinder 304 downwards until the pulley 306 squeezes the yarn. Friction imparts tension to the yarn during its movement. Simultaneously, the rotational connection between the pulley 306 and the connecting plate 305 prevents the yarn from jamming during the squeezing process. The tension applied to the yarn can be adjusted by controlling the squeezing force of the pulley 306, improving the applicability of the yarn guide structure. By adjusting the component 5, before using the yarn guide structure, the B servo motor 504 is powered, causing the B transmission rod 503 to drive the lead screw 502 to rotate. The threaded rod on the lead screw 502 pushes the B threaded cylinder 501 and the moving platform 4 to move horizontally along the lead screw 502, thereby changing the relative position of the yarn guide plate 1 and the yarn cylinder. This allows the yarn guide structure to adjust its position to avoid damaging the yarn and improve fabric quality.

[0027] Furthermore, sliding plates 6 are fixedly connected to both sides of threaded cylinder 304, and frame plates 2 are slidably connected to the surface of sliding plates 6;

[0028] During operation, the sliding plate 6 can limit the rotation of the threaded cylinder 304 and prevent it from shaking when rotating.

[0029] Furthermore, a slider 7 is fixedly connected to the bottom edge of the mobile platform 4, a slide rail 8 is slidably connected to the bottom of the slider 7, and a base plate 9 is fixedly connected to the bottom of the slide rail 8.

[0030] During operation, the slider 7 and the slide rail 8 are used to limit the rotation of the moving platform 4 while improving the stability of the moving platform 4.

[0031] Furthermore, the two ends of the slide rail 8 are fixedly connected to the limiting plate 10, the surface of the limiting plate 10 is rotatably connected to the lead screw 502, and the bottom of the limiting plate 10 is fixedly connected to the bottom plate 9.

[0032] During operation, the movement range of the mobile platform 4 can be limited by the setting of the limit plate 10.

[0033] Furthermore, a motor box 11 is fixedly connected to the surface of servo motor A 303, and a frame plate 2 is fixedly connected to the bottom of motor box 11;

[0034] During operation, the A servo motor 303 can be protected and vertically fixed by the A motor box 11.

[0035] Furthermore, a B motor box 12 is fixedly connected to the surface of the B servo motor 504, and a base plate 9 is fixedly connected to the bottom of the B motor box 12.

[0036] During operation, the B servo motor 504 can be protected and supported by the B motor box 12.

[0037] Working principle: Before using this yarn guide structure, servo motor B 504 is powered on, causing transmission rod B 503 to drive screw 502 to rotate. The thread on screw 502 pushes threaded cylinder B 501 and moving platform 4 to move horizontally along screw 502, thereby changing the relative position of guide plate 1 and yarn bobbin, preventing the yarn from connecting to guide plate 1 at too large an angle. When using this yarn guide structure, the yarn is passed through guide plate 1, and then servo motor A 303 is connected to the power supply, causing transmission rod A 302 to drive threaded rod 301 to rotate. The thread pushes threaded cylinder A 304 down until pulley 306 squeezes the yarn. Friction imparts tension to the yarn during its movement. At the same time, the rotational connection between pulley 306 and connecting plate 305 prevents the yarn from jamming during the squeezing process. The amount of yarn tension can be adjusted by controlling the squeezing force of pulley 306.
