[0002] A weft insertion and untwisting device is a specialized piece of equipment used in glass fiber weaving. During the weft insertion process of glass fiber yarn, it uses an untwisting mechanism to untwist the yarn, reducing its twist and thus decreasing the risk of yarn breakage, improving fabric quality and production efficiency. This device typically includes a weft insertion mechanism, an untwisting roller, a drive motor, and a control unit. It can automatically adjust the untwisting parameters according to the yarn characteristics, ensuring the stability and flexibility of the yarn during weft insertion.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figures 1 to 4 As shown, an embodiment of the present invention provides a glass fiber yarn weft insertion and untwisting device, comprising a base plate 1, on which a weft insertion mechanism is provided. The weft insertion mechanism includes: an untwisting assembly, comprising a pair of first support plates 2 fixedly attached to the base plate 1, a U-shaped groove 3 formed on the first support plate 2, a circular rod 4 placed in the U-shaped groove 3, an untwisting roller 5 fixedly attached to the circular rod 4, a first square block 6 fixedly attached to one end of the circular rod 4, and a second square block 7 rotatably connected to the other end of the circular rod 4; a rotation drive assembly for driving the first square block 6 is provided on the first support plate 2; a fixing assembly is provided on the first support plate 2 for fixing the second square block 7; and a yarn guiding assembly is provided on the base plate 1 for guiding the yarn.

[0026] The drive assembly includes a motor 8 fixed to the side wall of the first support plate 2 via an L-shaped block. The output end of the motor 8 is provided with a drive rod 9. The end of the drive rod 9 away from the motor 8 is fixed to a placement block 10. The first square block 6 is placed inside the placement block 10.

[0027] The fixing assembly includes a rectangular block 11 fixed to the side wall of the first support plate 2, a first through hole 12 on the second square block 7, a second through hole 13 on the rectangular block 11, and the rectangular block 11 and the second square block 7 are fixedly connected by bolts 14.

[0028] During operation, the untwisting roller 5 is placed on the first support plate 2 via the circular rod 4 and fixed by the first square block 6 and the second square block 7. The motor 8 drives the roller. This design allows the untwisting roller 5 to be quickly replaced according to the specifications and characteristics of different yarns, enhancing the flexibility and adaptability of the equipment. This avoids the problem in the prior art where the traditional untwisting roller 5 is fixed to the frame by welding or integrated design, which makes it impossible to replace quickly and limits the adaptability of the equipment to different yarns.

[0029] The yarn guiding assembly includes a pair of second support plates 15 fixed to the base plate 1, a pair of support bars 16 fixed between the opposite sidewalls of the pair of support plates, and a concave frame 17 slidably connected to the pair of support bars 16.

[0030] Rectangular holes 18 are provided on both sides of the concave frame 17. Sliding blocks 19 are slidably connected in the rectangular holes 18. A concave block 20 is fixed between the opposite side walls of a pair of sliding blocks 19. A guide wheel 21 is rotatably connected between the opposite side walls of the concave blocks 20 through a first rotating shaft. The bottom of the concave block 20 is connected to the concave frame 17 through a spring 22.

[0031] A threaded rod 23 is threadedly connected to the second support plate 15 through a threaded hole. A knob 24 is fixed to one end of the threaded rod 23, and the end of the threaded rod 23 away from the knob 24 is rotatably connected to the side wall of the concave frame 17.

[0032] During operation, the position of the guide wheel 21 can be adjusted by rotating the knob 24, which can flexibly adjust the guiding path of the yarn according to the yarn tension and weft insertion requirements, ensuring the stability and accuracy of the yarn during the weft insertion process. The guide wheel 21 is connected to the concave frame 17 through the spring 22, which can automatically adjust its position according to the yarn tension, maintain the yarn tension stability, and avoid the yarn from becoming too loose or too tight during the guiding process.

[0033] Working principle: After the motor 8 starts, the drive rod 9 at its output end drives the placement block 10 to rotate. The first square block 6 inside the placement block 10 rotates accordingly, which in turn drives the circular rod 4 and the untwisting roller 5 to rotate. Since the rotation direction of the untwisting roller 5 is opposite to the twisting direction of the yarn, the twist of the yarn is gradually unwound when it passes through the untwisting roller 5, realizing the untwisting function. The rectangular block 11 and the second square block 7 are fixedly connected by bolts 14. This fixing method ensures that the second square block 7 remains stable when the circular rod 4 rotates and will not be displaced, thereby ensuring the stable rotation of the untwisting roller 5 and ensuring the continuity and stability of the untwisting process.

[0034] After the yarn is drawn from the spindle, it first passes through the guide roller 21. The guide roller 21 is mounted on the concave block 20 via a first rotating shaft, allowing it to rotate freely and ensuring smooth and unobstructed passage of the yarn. The bottom of the concave block 20 is connected to the concave frame 17 via a spring 22. This structure allows the guide roller 21 to automatically adjust its position according to the yarn tension, maintaining stable yarn tension and preventing the yarn from becoming too loose or too tight during the guiding process.

[0035] Rotating the knob 24 causes the threaded rod 23 to rotate. Since the threaded rod 23 is threadedly connected to the threaded hole on the second support plate 15, the rotation of the threaded rod 23 will cause it to move axially along the threaded hole, thereby pushing the concave frame 17 to slide along the support bar 16, thus changing the position of the guide wheel 21. In this way, the guiding path of the yarn can be flexibly adjusted according to actual production needs and yarn characteristics, ensuring the stability and accuracy of the yarn during the weft insertion process.

Figure 1 Based on the perspective of the observer, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
