AI Technical Summary
The tension of the yarn in the existing shuttle is unstable during the change of the outlet point, which can easily lead to the filament breakage. Especially when recycled materials or additives are used, the tension changes even more.
A tensile balance shuttle is designed to introduce a balance assembly between the yarn roll and the porcelain eye, including a balance plate and a moving assembly, and the arc surface is used to make the length of any outlet point of the yarn roll to the porcelain eye equal, and the thread thickness changes are kept consistent with the movement of the balance plate through the detection unit and the moving assembly, ensuring that the tension of the thread is basically unchanged when the outlet point changes continuously.
It effectively reduces the tension change of the wire during the outgoing process, reduces the risk of wire breakage, and improves the stability and durability of the yarn.

Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of circular looms, and more particularly to a tension-balanced shuttle and a balance assembly. Background Art
[0002] Please refer to Figure 1 , in an old-fashioned shuttle, the yarn roll is placed horizontally relative to the shuttle track, and then the yarn is led out through a flagpole arranged beside the yarn roll. When leading out the yarn, the leading-out point changes back and forth between the two ends of the yarn roll (i.e., back and forth between points A, B, and C). Since the distance from point B to the yarn-leading porcelain eye is shorter than the distances from points A and C to the yarn-leading porcelain eye, when the yarn-leading speed remains unchanged, as the leading-out point changes on the yarn roll, the tension of the silk thread is constantly changing. The simplified diagram of the tension change can be referred to Figure 2 . If the tension of the silk thread keeps changing, it is likely to cause the breakage of the silk thread.
[0003] Please refer to Figure 3 , in a radial shuttle, the yarn roll is placed vertically relative to the shuttle track, and then the yarn-leading direction needs to be changed through the porcelain eye on the main frame of the shuttle and then led out by the flagpole. Compared with the old-fashioned shuttle, the yarn of the radial shuttle needs to pass through two porcelain eyes, so the distance between the first porcelain eye and the leading-out point is shorter than the distance between the porcelain eye and the leading-out point in the old-fashioned shuttle. Therefore, the tension change of the silk thread of the radial shuttle is greater and it is more likely to cause the breakage of the silk thread. And due to environmental protection issues and different usage conditions of the finished bags, recycled materials or calcium carbonate or other additives are often used, resulting in a relatively low tension value of the silk thread and being easily torn. Summary of the Invention
[0004] The purpose of the present invention is to provide a tension-balanced shuttle and a balance assembly, so that after the leading-out point changes continuously, the tension of the silk thread can be basically kept unchanged, making the silk thread not easy to break.
[0005] The technical solution adopted by the tension-balanced shuttle disclosed by the present invention is as follows:
[0006] A tension-balanced shuttle includes a frame body, a porcelain eye is provided on the frame body, and a yarn shaft for installing a yarn roll. It further includes a balance assembly. The balance assembly includes a balance plate, and the balance plate is provided with an arc surface. The silk thread is led out from the leading-out point of the yarn roll, passes through the arc surface and then reaches the porcelain eye. The arc surface makes the length of the silk thread from any leading-out point of the yarn roll to the porcelain eye equal.
[0007] As a preferred solution, the balance plate is arranged close to the yarn shaft.
[0008] As a preferred solution, the balance assembly further includes a moving assembly connected to the balance plate, and the moving assembly is used to drive the balance plate to move along the width direction of the yarn roll.
[0009] As a preferred solution, the balance assembly further includes a detection unit for obtaining the change value of the silk thread thickness on the yarn bobbin, and the distance that the moving assembly drives the balance plate to move is consistent with the change value of the silk thread thickness.
[0010] As a preferred solution, the moving assembly drives the balance plate so that the balance plate remains in contact with the silk thread on the yarn bobbin.
[0011] As a preferred solution, the moving assembly includes an elastic assembly in a compressed or stretched state, and the elastic assembly drives the balance plate to remain in contact with the silk thread on the yarn bobbin.
[0012] As a preferred solution, the elastic assembly includes a mounting bracket provided on the frame body, and an elastic member and a rotatable connecting member provided on the mounting bracket. The elastic member abuts against the connecting member, and the connecting member is rotatably connected to the balance plate.
[0013] As a preferred solution, a guiding chute is further formed on the mounting bracket, and a guiding protrusion is provided on the connecting member, and the guiding protrusion is arranged in the guiding chute.
[0014] This solution also provides a balance assembly, which includes a balance plate. The balance plate is provided with an arc surface. The silk thread is led out from the thread outlet point of the yarn bobbin, passes through the arc surface and then reaches the porcelain eye. The arc surface makes the length of the silk thread from any thread outlet point of the yarn bobbin to the porcelain eye equal.
[0015] The beneficial effects of the embodiments disclosed in the present invention are as follows: After the silk thread is led out from the thread outlet point of the yarn bobbin, it first passes through the arc surface of the balance plate and then reaches the porcelain eye. Since a balance plate is added between the thread outlet point and the porcelain eye, the path of the silk thread is changed, and through the arc surface of the balance plate, the length of the silk thread from any thread outlet point of the yarn bobbin to the porcelain eye is equal. Therefore, after the thread outlet point changes continuously, the tension of the silk thread can be basically kept unchanged, so that the silk thread is not easy to break.

[0026] The following further elaborates and explains the present invention in combination with specific embodiments and the accompanying drawings of the specification:
[0027] Please refer to Figure 4 、 Figure 5 and Figure 10 The tension balance type flying shuttle includes a frame body 10, a porcelain eye 12 is provided on the frame body 10, and a yarn shaft 14 for installing a yarn roll 30. It further includes a balance assembly 20, the balance assembly 20 includes a balance plate 21, the balance plate 21 is provided with a cambered surface 212, the silk thread is led out from the wire outlet point of the yarn roll 30 and reaches the porcelain eye 12 after passing through the cambered surface 212, and the cambered surface 212 makes the length from any wire outlet point of the yarn roll 30 to the porcelain eye 12 equal.
[0028] After the silk thread is led out from the wire outlet point of the yarn roll 30, it first passes through the cambered surface 212 of the balance plate 21 and then reaches the porcelain eye 12. Since the balance plate 21 is added between the wire outlet point and the porcelain eye 12, the path of the silk thread is changed, and through the cambered surface 212 of the balance plate 21, the length from any wire outlet point of the yarn roll 30 to the porcelain eye 12 is made equal. Therefore, after the wire outlet point changes continuously, the tension of the silk thread can be basically kept unchanged, making the silk thread not easy to break.
[0029] In this embodiment, since the silk thread needs to pass through the cambered surface 212 of the balance plate 21 and then reach the porcelain eye 12 after being led out from the wire outlet point of the yarn roll 30, the balance plate 21 can be arranged between the yarn roll 30 and the porcelain eye 12. In another implementation mode, the balance plate 21 may not be arranged between the yarn roll 30 and the porcelain eye 12, and at this time, the silk thread needs to pass through the cambered surface 212 and then wind back to the porcelain eye 12.
[0030] In this embodiment, the arc surface 212 of the balance plate 21 includes a high point and low points symmetrically distributed on both sides of the high point. The arc surface 212 includes at least two low points and one high point. When the balance plate 21 is not added, the distance from the wire outlet point to the porcelain eye 12 is such that the wire outlet points at both ends of the yarn roll 30 are farther away, while the wire outlet points in the middle are closer. This is exactly the opposite of the arc surface 212 with lower ends and a higher middle. Therefore, after the wire passes through the arc surface 212, the length from any wire outlet point to the porcelain eye 12 can be made equal. The radian of the arc surface 212 matches the length of the yarn roll 30.
[0031] Please refer to Figure 6 and Figure 7 , in this embodiment, the balance plate 21 is arranged close to the yarn shaft 14. Since the wire outlet point changes back and forth at both ends of the yarn roll 30, the wire will also swing back and forth on the arc surface 212 of the balance plate 21. Therefore, when the balance plate 21 is arranged close to the yarn shaft 14, the wire is more likely to swing back and forth on the arc surface 212 of the balance plate 21, avoiding the blockage caused by the swing of the wire, thereby affecting the change of the wire tension.
[0032] Please refer to again Figure 4 and Figure 7 , further, the balance assembly 20 further includes a moving assembly 22 connected to the balance plate 21, and the moving assembly 22 is used to drive the balance plate 21 to move along the width direction of the yarn roll 30. In this embodiment, as the wire is gradually consumed, the thickness of the wire will gradually decrease. Therefore, it is equivalent to the wire outlet point of the yarn roll 30 moving in its width direction. At this time, the straight-line distance from the wire outlet point to the arc surface 212 on the balance plate 21 will increase. Since the wire outlet point changes back and forth at both ends of the yarn roll 30, the wire will also swing back and forth on the arc surface 212 of the balance plate 21, and it is from the low point - high point - low point of the arc surface 212. When the straight-line distance from the wire outlet point to the arc surface 212 on the balance plate 21 increases, it will cause the friction force of the wire on the arc surface 212 to increase, especially the friction force between the low point and the high point of the arc surface 212, thereby making the back-and-forth swing of the wire on the arc surface 212 become blocked, resulting in a change in the wire tension. Therefore, by driving the balance plate 21 to move along the width direction of the yarn roll 30 through the moving assembly 22, the straight-line distance from the wire outlet point to the arc surface 212 on the balance plate 21 is basically unchanged, enabling the wire to swing back and forth smoothly on the arc surface 212, thereby ensuring that the wire tension is basically unchanged. The moving assembly 22 is used to provide a power for the balance plate 21 to move back and forth, such as a cylinder.
[0033] Further, the balance assembly 20 further includes a detection unit for obtaining the change value of the silk thread thickness on the yarn bobbin 14, and the distance that the moving assembly 22 drives the balance plate 21 to move is consistent with the change value of the silk thread thickness. In this embodiment, the detection unit can obtain the silk thread thickness through a length measuring sensor, and obtain the change value of the silk thread thickness by subtracting the real-time value of the silk thread thickness from the initial value of the silk thread thickness. The moving assembly 22 drives the balance plate 21 to move a corresponding distance, so that the straight-line distance from the wire outlet point to the arc surface 212 on the balance plate 21 remains unchanged.
[0034] Please refer to again Figure 5 、 Figure 6 and Figure 7 In another embodiment, the moving assembly 22 drives the balance plate 21 so that the balance plate 21 remains in contact with the silk thread on the yarn bobbin 14. In this embodiment, the moving assembly 22 keeps applying a thrust or a pulling force to the balance plate 21, so that the balance plate 21 is in contact with and abuts against the silk thread. When the silk thread is gradually consumed and the thickness of the silk thread gradually decreases, the moving assembly 22 drives the balance plate 21 to move as the thickness of the silk thread decreases and remains in contact with the silk thread. The straight-line distance from the wire outlet point to the arc surface 212 on the balance plate 21 remains unchanged, enabling the silk thread to swing smoothly back and forth on the arc surface 212, thereby ensuring that the tension of the silk thread remains basically unchanged. At the same time, since the balance plate 21 remains in contact with the silk thread, the balance plate 21 can also be used as a braking brake plate for the yarn bobbin 30 to prevent the yarn bobbin 30 from rotating due to rotational inertia.
[0035] Further, the moving assembly 22 includes an elastic assembly in a compressed or stretched state, and the elastic assembly drives the balance plate 21 to remain in contact with the silk thread on the yarn bobbin 14. In this embodiment, the elastic assembly drives the balance plate 21 to move after being compressed or stretched, and keeps it in contact with the silk thread on the yarn bobbin 14.
[0036] Please refer to Figure 8 and Figure 9, specifically, the elastic component includes a mounting bracket 23 provided on the frame 10, an elastic member 25 and a rotatable connecting member 24 provided on the mounting bracket 23. The elastic member 25 abuts against the connecting member 24, and the connecting member 24 is rotatably connected to the balance plate 21. In this embodiment, the elastic member 25 is a torsion spring. The torsion spring is mounted on a torsion spring seat on the mounting bracket 23. The torsion spring abuts against the connecting member 24 in a compressed state and pushes the connecting member 24 to move. The two ends of the connecting member 24 are respectively rotatably connected to the mounting bracket 23 and the balance plate 21, so that the balance plate 21 can be driven to move after rotation. In this embodiment, two connecting members 24 are provided to improve the stability of the movement of the balance plate 21. Further, a guiding chute 232 is also formed on the mounting bracket 23, and a guiding protrusion 242 is provided on one of the connecting members 24. The guiding protrusion 242 is arranged in the guiding chute 232. By restricting the sliding of the guiding protrusion 242 through the guiding chute 232, the connecting member 24 and the balance plate 21 can move more stably.
[0037] This embodiment also provides a balance component. The balance component 20 includes a balance plate 21. The balance plate 21 is provided with an arc surface 212. The silk thread is led out from the wire outlet point of the yarn reel 30, passes through the arc surface 212 and then reaches the porcelain eye 12. The arc surface 212 makes the length of the silk thread from any wire outlet point of the yarn reel 30 to the porcelain eye 12 equal.
[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
