Detailed Description
The invention will be further elucidated and described with reference to the following embodiments and drawings in which:
referring to fig. 4, 5 and 10, the tension balanced shuttle includes a frame 10, a porcelain eye 12 is provided on the frame 10, and a yarn shaft 14 for mounting a yarn reel 30. The yarn winding device further comprises a balance assembly 20, the balance assembly 20 comprises a balance plate 21, the balance plate 21 is provided with an arc surface 212, the yarn is led out from the yarn outgoing point of the yarn coil 30 and reaches the porcelain eye 12 after passing through the arc surface 212, and the arc surface 212 enables the length of the yarn from any yarn outgoing point of the yarn coil 30 to the porcelain eye 12 to be equal.
The thread is led out from the thread outlet point of the yarn coil 30, passes through the cambered surface 212 of the balance plate 21 and then reaches the porcelain eye 12. Because the balance plate 21 is added between the outgoing point and the porcelain eye 12, the path of the silk thread is changed, and the lengths from any outgoing point of the yarn coil 30 to the porcelain eye 12 are equal through the cambered surface 212 of the balance plate 21. Therefore, after the wire outlet point is changed continuously, the tension of the silk thread can be kept unchanged basically, so that the silk thread is not easy to break.
In this embodiment, since the filament needs to pass through the arc surface 212 of the balance plate 21 and reach the eyelet 12 after being drawn out from the yarn outlet point of the yarn roll 30, the balance plate 21 may be disposed between the yarn roll 30 and the eyelet 12. In another embodiment, the balancing plate 21 may not be disposed between the yarn roll 30 and the eyelet 12, and the yarn needs to pass through the arc 212 and then wind back to the eyelet 12.
In this embodiment, the arc surface 212 of the balance plate 21 includes a high point and low points symmetrically distributed on two sides of the high point, and the arc surface 212 includes at least two low points and a high point. When the balance plate 21 is not added, the distance from the outlet point of the silk thread to the porcelain eye 12 is that the outlet points at the two ends of the yarn coil 30 are far, and the outlet point in the middle is close. This is exactly opposite to the low ends and the high middle of the arc surface 212, so that the length from any outlet point to the porcelain eye 12 can be equal after the wire passes through the arc surface 212. While the arc of the arc 212 matches the length of the yarn package 30.
Referring to fig. 6 and 7, in the present embodiment, the balance plate 21 is disposed near the yarn bobbin 14. Since the thread can swing back and forth on the arc 212 of the balance plate 21 when the thread outlet point changes back and forth at the two ends of the yarn roll 30, when the balance plate 21 is arranged close to the yarn shaft 14, the thread can swing back and forth on the arc 212 of the balance plate 21 more easily, and the phenomenon that the tension change of the thread is influenced due to the damping generated by the swinging of the thread is avoided.
Referring to fig. 4 and 7, further, the balance assembly 20 further includes a moving assembly 22 connected to the balance plate 21, wherein the moving assembly 22 is configured to move the balance plate 21 along the width direction of the yarn roll 30. In this embodiment, as the yarn is gradually consumed, the thickness of the yarn is gradually reduced, which corresponds to the movement of the yarn outlet point of the yarn roll 30 toward the width direction thereof, and at this time, the linear distance from the yarn outlet point to the upper arc surface 212 of the balance plate 21 is increased. Since the yarn outlet point is changed back and forth at the two ends of the yarn coil 30, the yarn will swing back and forth on the cambered surface 212 of the balance plate 21 and is from the low point to the high point to the low point of the cambered surface 212. When the linear distance from the wire outlet point to the arc surface 212 on the balance plate 21 is increased, the friction force of the wire on the arc surface 212 is increased, especially the friction force between the low point and the high point of the arc surface 212, so that the back-and-forth swing of the wire on the arc surface 212 is retarded, and the tension of the wire is changed. Therefore, the moving assembly 22 drives the balance plate 21 to move along the width direction of the yarn coil 30, so that the linear distance from the yarn outgoing point to the arc surface 212 on the balance plate 21 is basically unchanged, the yarn can smoothly swing back and forth on the arc surface 212, and the tension of the yarn 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 an air cylinder.
Further, the balancing assembly 20 further includes a detecting unit, the detecting unit is configured to obtain a thickness variation value of the yarn on the yarn bobbin 14, and the moving assembly 22 drives the balancing plate 21 to move by a distance consistent with the thickness variation value of the yarn. In this embodiment, the detection unit may obtain the thickness of the silk thread through the length measuring sensor, and obtain the thickness variation value of the silk thread by subtracting the real-time value of the thickness of the silk thread from the initial value of the thickness of the silk thread, and the moving component 22 drives the balance plate 21 to move by a corresponding distance, so that the linear distance from the line outgoing point to the upper arc surface 212 of the balance plate 21 is unchanged.
Referring again to fig. 5, 6 and 7, in another embodiment, the moving assembly 22 drives the balancing plate 21 such that the balancing plate 21 is kept in contact with the threads on the yarn bobbin 14. In this embodiment, the moving component 22 keeps applying a pushing force or a pulling force to the balance plate 21, so that the balance plate 21 abuts against the silk thread and is abutted against the silk thread, when the silk thread is gradually consumed and the thickness of the silk thread is gradually reduced, the moving component 22 drives the balance plate 21 to move along with the reduction of the thickness of the silk thread and keep abutting against the silk thread. The linear distance from the wire outlet point to the arc surface 212 on the balance plate 21 is not changed, and the silk thread can smoothly swing back and forth on the arc surface 212, so that the tension of the silk thread is basically unchanged. At the same time, since the balancing plate 21 is held in contact with the thread, the balancing plate 21 also acts as a braking plate for the yarn package 30, preventing the yarn package 30 from rotating due to the inertia of rotation.
Further, the moving element 22 comprises an elastic element in a compressed or stretched state, which brings the balancing plate 21 into abutment with the thread on the yarn spool 14. In this embodiment, the elastic member compresses or stretches and then moves the balance plate 21, and keeps it in contact with the yarn on the yarn shaft 14.
Referring to fig. 8 and 9, in particular, the elastic assembly includes a mounting bracket 23 disposed on the frame body 10, and an elastic member 25 and a rotatable connecting member 24 disposed on the mounting bracket 23, wherein 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 of the mounting frame 23, and the torsion spring is in a compressed state and abuts against the connecting member 24, and pushes the connecting member 24 to move. And the two ends of the connecting member 24 are rotatably connected to the mounting frame 23 and the balance plate 21, respectively, so that the balance plate 21 is driven to move after the rotation. In this embodiment, two connecting members 24 are provided to improve the stability of the movement of the balance plate 21. Further, a guide sliding groove 232 is further formed in the mounting frame 23, a guide protrusion 242 is arranged on one of the connecting pieces 24, and the guide protrusion 242 is arranged in the guide sliding groove 232. The sliding of the guide projection 242 is restricted by the guide slide groove 232, so that the link 24 and the balance plate 21 perform more stable movement.
The embodiment also provides a balance assembly, the balance assembly 20 comprises a balance plate 21, the balance plate 21 is provided with an arc surface 212, the silk thread is led out from the outlet point of the yarn coil 30 and reaches the porcelain eye 12 after passing through the arc surface 212, and the arc surface 212 enables the length of the silk thread from any outlet point of the yarn coil 30 to the porcelain eye 12 to be equal.
It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
