Detailed Description
To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1, an embodiment of the present invention provides an automatic yarn winding device 10, which includes a yarn feeding mechanism 100, a gravity mechanism 200, and a winding mechanism 300.
The thread-guiding mechanism 100 is used to introduce the yarn 20 to be wound.
The gravity mechanism 200 includes a vertical slide bar 210, a wire hanging cross bar 220, and a sensing component (not shown). The thread hanging cross bar 220 is arranged on the vertical sliding rod 210 and can move along the vertical sliding rod 210 within a preset height, and the thread hanging cross bar 220 is used for winding the yarn 20 introduced by the thread leading mechanism 100, so that the yarn 20 bears the thread hanging cross bar 220. The sensing component is used for sensing whether the wire hanging cross rod 220 moves to the highest point and the lowest point of the preset height.
Referring to fig. 2, the winding mechanism 300 includes a winding motor 310 and a rotating assembly (not shown), wherein the winding motor 310 is used for driving the rotating assembly to rotate so as to wind the yarn 20 on the yarn hanging rail 220 onto the bobbin. The winding motor 310 is used for adjusting the rotation speed of the rotating assembly when the sensing assembly senses that the thread hanging cross rod 220 moves to the highest point and the lowest point, so that the yarn 20 drives the thread hanging cross rod 220 to move between the highest point and the lowest point of the preset height.
When the automatic yarn winding device 10 works, the yarn 20 to be wound enters the gravity mechanism 200 from the yarn leading mechanism 100, so that the yarn 20 is wound on the yarn hanging cross bar 220 from bottom to top and bears the yarn hanging cross bar 220, and then enters the winding mechanism 300 for winding. In the winding process, the yarn 20 gets tighter and tighter, and the yarn 20 drives the yarn hanging cross bar 220 to move upwards along the vertical sliding bar 210 until reaching the highest point; and as the yarn 20 loosens, the thread hanging rail 220 loses the load bearing effect of the yarn 20 and moves down the vertical sliding rod 210 to the lowest point. When the thread hanging cross rod 220 moves to the highest point of the preset height, the rotating speed of the rotating assembly is adjusted through the winding motor 310, so that the yarn 20 drives the thread hanging cross rod 220 to move downwards to the lowest point; when the thread hanging cross rod 220 moves to the lowest point of the preset height, the rotating speed of the rotating assembly is adjusted through the winding motor 310, so that the yarn 20 drives the thread hanging cross rod 220 to move upwards to the highest point, the yarn 20 drives the thread hanging cross rod 220 to move between the highest point and the lowest point of the preset height, the problems that the yarn 20 is too tightly pulled and the yarn 20 is too loose and piled are further avoided, and the winding effect is improved.
It will be appreciated that the preset height of vertical slide bar 210 is set according to parameters such as acceptable yarn tension. The automatic yarn winding device 10 can flexibly adjust the winding speed according to the arrangement of the gravity mechanism 200 and the winding mechanism 300, and further can meet the requirement that the slasher outputs yarns at different linear speeds, in other words, even if the linear speed of the slasher is changed, the winding mechanism 300 can also be flexibly adjusted, and the problem that the yarns are broken or loose and piled cannot be caused.
It is understood that the automatic yarn winding device 10 further includes a frame (not shown), and the yarn feeding mechanism 100, the gravity mechanism 200 and the winding mechanism 300 are disposed on the frame.
It is understood that the highest point and the lowest point of the preset height include the highest point and the lowest point.
In some embodiments, the sensing assembly includes a first sensor 231 and a second sensor 232, and the first sensor 231 and the second sensor 232 are respectively used for sensing whether the wire hanging rail 220 moves to the highest point and the lowest point of the preset height.
The winding motor 310 is used for stopping working or controlling the rotating assembly to reduce the rotating speed when the first sensor 231 senses that the wire hanging cross bar 220 moves to the highest point, so that the wire hanging cross bar 220 moves to the lowest point. Therefore, when the yarn is wound too fast, the yarn hanging cross rod 220 is pulled to the highest point, the first sensor 231 on the yarn hanging cross rod is triggered, and at the moment, the winding motor 310 stops winding or controls the rotating assembly to reduce the rotating speed, so that the yarn is prevented from being pulled apart due to the pulling of the winding motor 310.
The winding motor 310 is further used for restarting or controlling the rotating assembly to increase the rotating speed when the second sensor 232 senses that the wire hanging cross bar 220 moves to the lowest point, so that the wire hanging cross bar 220 moves to the highest point by the winding motor 310. Thus, when the yarn is in a relaxed state, the thread-hooking rail 220 will fall to the lowest point, and the second sensor 232 below is triggered, at which time the winding motor 310 restarts to wind the yarn or control the rotating assembly to increase the rotating speed.
It is understood that in some embodiments, if the wire hanging cross bar 220 is at the highest point, the wire winding motor 310 stops; while the slasher continues to deliver yarn, thereby causing the thread hanging rail 220 to move to the lowest point. When the thread hanging cross rod 220 is at the lowest point, the winding motor 310 restarts to work, and the winding motor 310 controls the linear speed of the rotating assembly to be greater than the yarn speed output by the slasher. Further, the winding motor 310 is operated intermittently, and the linear speed of the winding motor 310 is always set to be greater than the yarn speed output by the slasher. In this way, when the automatic yarn winding device 10 is operated, the yarn hanging rail 220 moves back and forth between the highest point and the lowest point along the vertical sliding rod 210.
In other embodiments, when the wire hanging cross bar 220 is at the highest point, the winding motor 310 controls the rotating assembly to reduce the rotating speed; while the slasher continues to deliver yarn 20, thereby moving the thread hanging rail 220 to the lowest point. When the thread hanging cross rod 220 is at the lowest point, the winding motor 310 controls the rotating assembly to increase the rotating speed, and the winding motor 310 controls the linear speed of the rotating assembly to be greater than the yarn speed output by the slasher. Further, the winding motor 310 can operate without stopping, but the linear speed thereof needs to be adjustable, for example, adjusted to be less than or greater than the yarn speed output by the slasher; but of course can be equal to the yarn speed output by the slasher. In this way, when the automatic yarn winding device 10 is operated, the yarn hanging rail 220 moves back and forth between the highest point and the lowest point along the vertical sliding rod 210.
Referring to fig. 1, in some embodiments, the gravity mechanism 200 includes two vertical sliding rods 210 arranged at intervals, and two ends of the wire hanging cross bar 220 are respectively disposed on the two vertical sliding rods 210, so as to facilitate stability of the movement of the wire hanging cross bar 220 along the vertical sliding rods 210.
Further, the gravity mechanism 200 further includes a linear bearing 240, and the wire hanging cross bar 220 is disposed on the vertical sliding bar 210 through the linear bearing 240.
In some embodiments, the lead mechanism 100 includes a lead rod 110 and a third inductor 120, and a lead loop (not shown) is disposed on the lead rod 110. The third sensor 120 is used for sensing whether the yarn is on the lead rod 110, and the winding motor 310 is used for stopping working when the third sensor 120 senses that the yarn is not on the lead rod 110. Therefore, when the yarn is completely drawn, the third sensor 120 should have no yarn, and the winding motor 310 will stop immediately, which is beneficial to the safety of operation.
Further, a third inductor 120 is provided at an end of the lead bar 110. Specifically, one end of the lead rod 110 is disposed on the frame, and the other end is disposed with the third inductor 120.

Furthermore, the outer surface of the front end of each section of hollow tube is provided with a thread guiding ring for threading.
Further, the lead mechanism 100 further includes a support rod 130, the support rod 130 is disposed perpendicular to the lead rod 110, and the support rod 130 may also be provided with a lead ring. Furthermore, the wire guiding mechanism 100 further includes a wire guiding rod 140, and the wire guiding rod 140 is disposed between the supporting rod 130 and the wire hanging cross rod 220 for guiding the wire.

Thus, the spring top block 325 is arranged at the front end of the spring moving shaft 324, and the bobbin is pressed by the spring top block 325 so as to be clamped between the two rotary top blocks; when the bobbin is loosened, the bobbin can be taken out only by pulling the spring top block 325, and the structure diagram of the winding mechanism 300 without the bobbin is shown in fig. 4.
Referring to fig. 3, the rotating assembly further includes a pressing roller 326, and the pressing roller 326 is disposed on the fixing bracket 321 and is used for pressing and holding the yarn 20 of the bobbin.
