Description

Technical Field

[0001] This utility model relates to the field of fabric warping machine technology, and in particular to a tension compensation mechanism for fabric warping machines. Background Technology

[0002] The warping process refers to the process of winding a certain number of warp yarns in parallel on a warp beam or weaving beam according to a specified length and width. According to the process design, a certain number and length of warp yarns are drawn from the winding bobbin to form a yarn sheet, so that the warp yarns have uniform tension and are tightly wound in parallel on the warping beam, making preliminary preparations for the formation of the weaving beam.

[0003] A search revealed a Chinese patent (authorization announcement number CN210796779U) disclosing a tension mechanism for a warping machine. This mechanism includes a baffle with magnetic holes and a wheel seat fixedly connected to the baffle. Three tension wheels are rotatably connected to the wheel seat, arranged in an equilateral triangle. The wheel seat has vertically distributed grooves and adjustment slots. Adjustment wheels are symmetrically distributed inside the grooves. A threaded rod is rotatably connected inside the adjustment slot, and a slider is threadedly connected to the outside of the threaded rod. This patented technology allows for tension adjustment by selecting a suitable tension wheel weight. Furthermore, the rotation of the turntable causes the slider to slide within the adjustment slot, and the connecting rods at both ends further adjust the yarn winding method to regulate the tension. This simplifies the yarn tension adjustment process.

[0004] However, the above-mentioned device still has some drawbacks in actual use. The most obvious one is that the device drives the tension wheel to spread to both sides by rotating the threaded rod. However, when the external pressure is large, the threaded rod will rotate on its own due to the squeezing force. In actual application, since different yarns require different tensions, when a large tension needs to be provided to the yarn, the threaded rod will slip back, thereby reducing the tension adjustment effect of the warping machine. Utility Model Content

[0005] In view of the above-mentioned problems existing in the prior art, the main purpose of this utility model is to provide a tension compensation mechanism for a fabric warping machine.

[0006] The technical solution of this utility model is as follows: a tension compensation mechanism for a fabric warping machine includes a wheel seat, a vertical groove b is provided inside the wheel seat, a screw is rotatably connected inside the vertical groove b, a mounting seat is fixedly installed on the outside of the wheel seat and below the screw, a rotating shaft is rotatably connected inside the mounting seat, a snap-fit ​​seat is fixedly connected to the outside of the rotating shaft, torsion springs are sleeved on both sides of the rotating shaft, one end of the torsion spring is connected to the snap-fit ​​seat, and the other end of the torsion spring is connected to the mounting seat. Both the mounting seat and the snap-fit ​​seat have anti-slip grooves inside for cooperation with the screw.

A limit rod is fixedly connected inside the transverse groove. Sliding members a are slidably connected to both ends of the outer side of the limit rod. Adjustment wheels are rotatably mounted on the outer side of each sliding member a.

[0011] By adopting the above technical solution, the connecting rod can drive the corresponding adjusting wheel to expand or contract, thereby adjusting the tension according to actual usage requirements.

[0012] In a preferred embodiment, the adjusting assembly further includes a fixed shaft fixedly connected to the outside of the sliding member a. The fixed shaft passes through the adjusting wheel and is rotatably connected to a connecting rod on its outside. The screw is threadedly connected to a threaded component on its outside, and the end of the connecting rod away from the adjusting wheel is rotatably connected to the threaded component.

[0016] In a preferred embodiment, the horizontal groove is disposed between the vertical groove b and the vertical groove a, and the bottom end of the screw extends between the snap-fit ​​seat and the mounting seat.

[0017] By adopting the above technical solution, it is convenient for the snap-fit ​​seat and the mounting seat to limit the screw.

[0018] In a preferred embodiment, the threaded component is slidably connected to the inner wall of the vertical groove b, and a yarn is provided between the tension wheel, the adjusting wheel and the driving wheel.

[0019] By adopting the above technical solution, the stable placement of the yarn can be ensured.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] 1. In this utility model, when the operator needs to adjust the tension, the locking seat can be moved to release the locking seat from the screw, thereby allowing the screw to rotate. After the tension is adjusted, the operator only needs to release the locking seat, and the reaction force of the torsion spring can push the locking seat back to its original position, so that the anti-slip groove on the mounting base and the locking seat can press against and limit the screw, thereby preventing the screw from sliding back due to excessive tension, thus ensuring the tension adjustment effect.

[0022] 2. In this invention, when the yarn suddenly becomes taut, the dampers on both sides of the drive wheel absorb the instantaneous impact force of the yarn to prevent the yarn from breaking. Attached Figure Description

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] Reference Figure 1-4 A tension compensation mechanism for a fabric warping machine includes a wheel seat 1. A vertical groove b20 is formed inside the wheel seat 1, and a screw 12 is rotatably connected inside the vertical groove b20. A mounting base 15 is fixedly installed on the outer side of the wheel seat 1, below the screw 12. A rotating shaft 17 is rotatably connected inside the mounting base 15, and a snap-fit ​​seat 16 is fixedly connected to the outer side of the rotating shaft 17. Torsion springs 18 are fitted on both sides of the rotating shaft 17. One end of the torsion spring 18 is connected to the snap-fit ​​seat 16, and the other end of the torsion spring 18 is connected to the mounting base 15. Both the mounting base 15 and the snap-fit ​​seat 16 have internal openings that cooperate with the screw 12 to... The anti-slip groove 19 is used so that when the tension needs to be adjusted, the locking seat 16 can be moved to release the locking seat 16 from the limit of the screw 12, so that the screw 12 can be rotated. After the tension is adjusted, the operator only needs to release the locking seat 16. Through the reaction force of the torsion spring 18, the locking seat 16 can be pushed to reset, so that the anti-slip groove 19 on the mounting base 15 and the locking seat 16 can be pressed and limited against the screw 12, thereby preventing the screw 12 from sliding back due to excessive tension, thus ensuring the tension adjustment effect.

[0030] Specifically, the wheel seat 1 is equipped with an anti-impact component, which includes a vertical groove a13 inside the wheel seat 1. When the yarn 14 suddenly tightens, the dampers 9 on both sides of the drive wheel 8 absorb the instantaneous impact force of the yarn 14 to prevent the yarn 14 from breaking. A sliding member b10 is slidably connected inside the vertical groove a13, and the drive wheel 8 is rotatably mounted on the outside of the sliding member b10. Damperes 9 are installed between the sliding member b10 and the inner wall of the vertical groove a13. The wheel seat 1 is also equipped with an adjustment component, which includes a horizontal groove 3 inside the wheel seat 1. A limit rod 7 is fixedly connected inside the horizontal groove 3, and two limit rods 9 are fixedly connected on the outside of the limit rod 7. Each end of the screw 12 is slidably connected to a sliding member a4. By rotating the screw 12, the threaded member 11 can slide within the vertical groove b20. This allows the connecting rod 5 to drive the corresponding adjusting wheel 6 to expand or contract, thereby adjusting the tension according to actual usage requirements and improving the applicability of the device. The outer side of the sliding member a4 is rotatably mounted with an adjusting wheel 6. The adjusting assembly also includes a fixed shaft fixedly connected to the outer side of the sliding member a4. The fixed shaft passes through the adjusting wheel 6 and is rotatably connected to the outer side of the fixed shaft with a connecting rod 5. The outer side of the screw 12 is threadedly connected to a threaded member 11. The end of the connecting rod 5 away from the adjusting wheel 6 is rotatably connected to the threaded member 11.

[0031] Specifically, two tension wheels 2 are rotatably mounted on the outer side of the wheel seat 1. The two tension wheels 2 are respectively set on both sides of the vertical groove b20. The horizontal groove 3 is set between the vertical groove b20 and the vertical groove a13. The bottom end of the screw 12 extends to the space between the snap-fit ​​seat 16 and the mounting seat 15, so that the snap-fit ​​seat 16 and the mounting seat 15 can limit the screw 12. The threaded part 11 is slidably connected to the inner wall of the vertical groove b20. A yarn 14 is set between the tension wheel 2, the adjusting wheel 6 and the driving wheel 8 to ensure the stable placement of the yarn 14.

[0032] Working principle: First, the operator can pass the yarn 14 through the tension wheel 2, the adjusting wheel 6, and the driving wheel 8 in sequence. When the operator needs to adjust the tension, the locking seat 16 can be moved to release the locking seat 16 from the limit of the screw 12, so that the screw 12 can be rotated. Through the rotation of the screw 12, the threaded part 11 can be driven to slide in the vertical groove b20, and then the corresponding adjusting wheel 6 can be opened or closed by the connecting rod 5. In this way, the tension can be adjusted according to the actual use needs. After the tension is adjusted, the operator only needs to release the locking seat 16. Through the reaction force of the torsion spring 18, the locking seat 16 can be pushed to reset, so that the anti-slip groove 19 on the mounting base 15 and the locking seat 16 can be pressed and limited against the screw 12, thereby preventing the screw 12 from sliding back due to excessive tension.
