Abstract
Description
Technical Field
[0001] This utility model relates to the field of polyester fabric technology, specifically to a polyester fabric tensioning mechanism. Background Technology
[0002] Polyester fabric is a very common synthetic fiber material in daily life. It is widely used in clothing, home furnishings and industrial fields due to its high cost performance and functionality. In the production of polyester yarn, tension control is a key step. Appropriate tension can stretch the fiber evenly, improving its strength and abrasion resistance; if the tension is too low, the fiber may loosen and knot, affecting the quality; if the tension is too high, it may damage the fiber structure and reduce elasticity.
[0003] To prevent wrinkles from forming when rolling up polyester fabric, a tensioning mechanism is needed to adjust the tension of the textile. However, the existing tensioning mechanism of the winding device is not convenient for users to adjust the tension, wasting a lot of users' time, reducing the practicality of the winding device, and the wrinkle removal effect is not ideal.
[0004] The prior art proposes a Chinese patent with publication number CN214569524U to solve the above-mentioned technical problems. The technical solution disclosed in this patent document is as follows: A winding device for processing polyester fabric with tension adjustment function, including an operating U-shaped plate, a tension adjustment housing fixedly installed on the left inner wall of the operating U-shaped plate, a rotating motor fixedly installed on the left wall of the operating U-shaped plate, the output end of the rotating motor rotatably passing through the left wall of the operating U-shaped plate and the tension adjustment housing and fixedly connected to a winding shaft, a rotating threaded rod rotatably installed on the inner bottom wall of the tension adjustment housing, and a rotating end rotatably passing through the upper wall of the tension adjustment housing fixedly installed on the upper end of the rotating threaded rod. This invention allows for manual rotation of the rotating end to drive the rotating threaded rod, which in turn adjusts the position of the two tension-adjusting threaded sleeves, thus adjusting the tension of the winding. The operation is very convenient. The upper and lower winding shafts have a tensioning effect on the polyester fabric. The operation is simple and convenient, but the polyester fabric may move horizontally during the winding process due to differences in actual width, which affects the tensioning effect.

[0029] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The tensioning mechanism for this polyester fabric specifically includes:
[0030] Base 1; an electric push rod 10 is fixedly installed on the top of the base 1, and a movable frame 11 is fixedly connected to the top of the electric push rod 10.

A fixed frame 2 is fixedly connected to the top of the base 1 on the outer side of the roller group 17. A rotating roller 3 is rotatably installed on the inner end of the fixed frame 2. A controller 4 is fixedly connected to one end of the fixed frame 2 on one side of the roller group 17. A limit roller 6 is rotatably connected to the inner end of the fixed frame 2 on the outer side of the rotating roller 3. A pair of baffles 13 are slidably connected to the outer surface of the guide roller 12. An adjustment component for adjusting the position of the baffle 13 is provided on the top of the baffle 13. A pair of limit plates 5 are slidably connected to the outer surface of the rotating roller 3. A guide component for adjusting the position of the limit plate 5 is provided on the top of the limit plate 5.
[0031] Specifically, the adjusting component includes a bidirectional screw 14, which is located on top of the baffle 13. Both ends of the bidirectional screw 14 are rotatably connected to the movable frame 11. A motor 15 is fixedly installed at one end of the movable frame 11. The output shaft of the motor 15 is fixedly connected to the bidirectional screw 14. A pair of movable plates 16 are threadedly installed on the outer surface of the bidirectional screw 14. A limit block 20 is fixedly installed at the inner end of the movable plate 16 at the bottom of the bidirectional screw 14. The limit block 20 is snapped into the interior of the baffle 13. An inclined surface is opened inside the baffle 13 at the top of the limit block 20. A second ranging sensor 23 is fixedly installed on the inner end surface of the baffle 13.
[0032] Specifically, the top of the limiting block 20 is provided with an inclined surface, which is in contact with the inclined surface of the baffle 13.
[0033] Specifically, a number of movable rods 22 are rotatably installed inside the limiting block 20, and the top of the movable rods 22 is in contact with the inclined surface of the baffle 13.
[0034] Specifically, the guiding component includes a bidirectional lead screw 7, which is located on top of the rotating roller 3, and both ends of the bidirectional lead screw 7 are rotatably connected to the fixed frame 2. A motor 8 is fixedly installed at one end of the fixed frame 2, and the output shaft of the motor 8 is fixedly connected to the bidirectional lead screw 7. A pair of sliding plates 9 are threaded on the outer surface of the bidirectional lead screw 7. A locking block 19 is fixedly installed at the inner end of the sliding plate 9 at the bottom of the bidirectional lead screw 7. The locking block 19 is engaged with the inside of the limiting plate 5. An inclined surface is opened inside the limiting plate 5 at the top of the locking block 19. A first ranging sensor 18 is fixedly installed on the inner surface of the limiting plate 5.
[0035] Specifically, the top of the card block 19 is provided with a slope, which is in contact with the slope of the limiting plate 5.
[0036] Specifically, a number of rotating rods 21 are rotatably installed inside the locking block 19, and the top of the rotating rods 21 is in contact with the inclined surface of the limiting plate 5.
[0037] In this embodiment, to prevent the polyester fabric from moving in the horizontal direction, reference is made. Figure 1 , Figure 3 and Figure 4 The specific implementation is as follows: When the polyester fabric contacts the guide roller 12, the second distance sensor 23 can detect the distance between the baffle 13 and the polyester fabric. When the distance between the baffle 13 and the polyester fabric is detected to be greater than the specified standard, the result can be transmitted to the controller 4. The controller 4 then controls the motor 15 to drive the bidirectional screw 14 to rotate, thereby driving the two movable plates 16 to move inward and pushing the baffle 13, so that the distance between the baffle 13 and the polyester fabric reaches the specified standard, thereby reducing the horizontal movement of the polyester fabric around the guide roller 12. The movement of the polyester fabric is controlled by the first distance sensor 18. When the polyester fabric comes into contact with the roller 3, the distance between the limiting plate 5 and the polyester fabric is detected by the first distance sensor 18. When the distance between the limiting plate 5 and the polyester fabric is detected to be greater than the specified standard, the result can be transmitted to the controller 4. The controller 4 then controls the motor 8 to drive the bidirectional lead screw 7 to rotate, thereby driving the two slide plates 9 to move inward and pushing the limiting plate 5, so that the distance between the limiting plate 5 and the polyester fabric reaches the specified standard, thereby reducing the horizontal movement of the polyester fabric on the periphery of the roller 3 and improving the tensioning and winding effect.
[0038] In this embodiment, in order to reduce the friction between the baffle 13 and the rotating roller 3 and the guide roller 12 and the rotating roller 3 respectively during the movement, reference is made. Figure 2 , Figure 5 and Figure 6The specific implementation method is as follows: During the movement of the movable plate 16, the limiting block 20 can be moved towards the interior of the baffle 13 first, and the baffle 13 can be pressed upward a certain distance, so that the baffle 13 separates from the surface of the guide roller 12. Then the movable plate 16 continues to press the baffle 13, so that the baffle 13 moves inward. After the baffle 13 approaches the polyester fabric and stops, due to the action of gravity, the baffle 13 slides inward along the movable rod 22, and the baffle 13 is once again in contact with the surface of the guide roller 12, so that the baffle 13 is just in contact with the polyester fabric, thereby achieving the desired effect. The polyester fabric is subjected to a limiting treatment. During the movement of the slide plate 9, the locking block 19 can be driven to move inward towards the limiting plate 5. At the same time, the limiting plate 5 can be squeezed upward a certain distance, so that the limiting plate 5 is separated from the surface of the rotating roller 3. Then the slide plate 9 continues to squeeze the limiting plate 5, so that the limiting plate 5 moves inward. After the limiting plate 5 approaches the polyester fabric and stops, due to the effect of gravity, the limiting plate 5 slides inward along the rotating rod 21. The limiting plate 5 is once again in contact with the surface of the rotating roller 3, so that the limiting plate 5 is just in contact with the polyester fabric, thereby achieving the limiting treatment of the polyester fabric.
