Description

Technical Field

[0001] The invention relates to the technical field of silk winding machines, in particular to an automatic yarn guiding device of a silk winding machine. Background Art

[0002] The winding machine, also known as the bobbin winder or yarn winder, is an important equipment in the post-spinning and preparation process. The process requirements of the winding machine include: appropriate winding tension without damaging the original physical and mechanical properties of the yarn; large bobbin winding capacity, good formation, and easy unwinding; small and firm yarn joints, and try to form knot-free yarn; the bobbin used for warping should be of fixed length, and the bobbin structure used for dyeing should be uniform.

[0003] In the process of using the winding machine to lead and twist the yarn, the one-way lead and twisting is relatively slow. After the twisting is completed, it needs to be replaced manually. The one-way lead will be idle during the line change process, which wastes time and increases labor costs. For this reason, we provide an automatic yarn leading device for the winding machine, which can make full use of the working time of the machine and avoid the idle waiting that may occur during one-way lead, thereby significantly improving the output per unit time. At the same time, the two-way lead reduces the time interval between yarn replacement and restart. Summary of the invention

[0004] The object of the present invention is to provide an automated yarn drawing device for a winding machine, so as to solve the problem raised in the above-mentioned background technology that in the process of using the winding machine to draw and twist yarn, the unidirectional drawing and twisting is relatively slow, and after the twisting is completed, it still needs to be replaced manually. In the process of changing the unidirectional drawing, idle belts will appear, which wastes time and increases labor costs. To achieve the above-mentioned purpose, the present invention provides the following technical scheme: an automatic yarn guiding device of a silk winding machine, comprising a U-shaped frame, wherein two connecting frames are fixedly connected to opposite sides of the vertical sides of the U-shaped frame, and the two connecting frames are symmetrically distributed, and a rotating disk is fixedly connected to the opposite side of each connecting frame, and the two rotating disks are symmetrically distributed, and the side surface of each rotating disk is movably connected to a rotating ring, and the two rotating rings are symmetrically distributed, and an annular groove is respectively provided on the opposite side of the two rotating rings, and the two annular grooves are symmetrically distributed, and a plurality of connecting rollers are movably connected to the inside of the two annular grooves, and the connecting rollers are distributed in an annular array, and a rotating bearing is fixedly connected to the inside of each rotating disk, and the connecting frame is fixedly connected to the side surface of the rotating bearing, and a plurality of winding wheels are fixedly connected to the opposite side of the two rotating disks, and the winding wheels are distributed in an annular array, when advancing When the device is used, it is first placed in a suitable position for use. During the yarn drawing process, the yarn required for yarn drawing must first be wound around the side surface of the winding wheel for fixing. After fixing, the rotating fan is driven by an external motor to rotate, so that the blades of the rotating fan drive the connecting roller to rotate, so that the rotating ring rotates to twist the yarn. During the yarn twisting process, the limiting triangle block and the connecting rod limit each other, so that the two rotating discs rotate in both directions to draw and twist the yarn. The bidirectional yarn drawing can achieve uninterrupted continuous operation, avoiding the pause of reloading yarn due to yarn exhaustion or end during unidirectional yarn drawing. In large-scale textile production, it can significantly improve production efficiency. At the same time, there is no need to frequently change the starting position and direction of the yarn, which greatly shortens the time for yarn replacement and preparation, thereby increasing the winding output per unit time.

[0005] Further preferably, the interior of the rotating disk is fixedly connected to an outer ring, the interior of the outer ring is fixedly connected to an inner ring, the interior of the inner ring is movably connected to a plurality of rollers and the rollers are distributed in a ring array, the interior of the inner ring is fixedly connected to a transmission ring, the inner ring is transmission-connected to the transmission ring via a plurality of rollers, and the side surface of the inner ring is fixedly connected to a connecting rod.

[0006] Further preferably, the inner wall of the rotating ring is fixedly connected with a limiting triangular block, the limiting triangular block is adapted to the connecting rod, and the rotating ring, rotating disc, outer ring, inner ring and transmission ring are all annular and gradually sleeved and adapted to each other.

[0007] Further preferably, the roller and the connecting roller are cylindrical respectively, the limiting triangle block is triangular, and a clearance groove is provided inside a horizontal surface of the U-shaped frame.

[0008] Further preferably, a rotating fan is fixedly connected inside the air avoidance groove and the rotating fan is meshed with a connecting roller, and extension plates are fixedly connected to both sides of the U-shaped frame and the two extension plates are symmetrically distributed.

[0009] Further preferably, the bottom of each of the extension plates is fixedly connected to two supporting legs and the two supporting legs are symmetrically distributed. When the device is used, the specific two-way rotation method is that when the rotating ring rotates, the rotating disc is driven to rotate. During the rotation, the limiting triangle blocks inside the two rotating discs are symmetrically mirrored with the connecting rod. When the rotating ring rotates, the two rotating discs can be prompted to rotate in both directions. When one rotating disc rotates clockwise, the other rotating disc can rotate counterclockwise, thereby releasing the yarn. This makes the device have high stability and flexibility, which can make full use of the working time of the machine and avoid idle waiting that may occur during one-way threading, thereby significantly improving the output per unit time. At the same time, the two-way threading reduces the time interval between yarn replacement and restarting.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] In the present invention, when the device is used, the device is first placed in a suitable position for use. In the process of yarn drawing, the yarn required for yarn drawing needs to be wound around the side surface of the winding wheel for fixing. After fixing, the rotating fan is driven by an external motor to rotate, so that the blades of the rotating fan drive the connecting roller to rotate, so that the rotating ring is rotated to twist the yarn. In the process of yarn twisting, the limiting triangle block and the connecting rod are mutually limited, so that the two rotating discs rotate in both directions to carry out yarn drawing and twisting. Bidirectional yarn drawing can realize uninterrupted continuous operation, avoiding the pause of reloading yarn due to yarn exhaustion or end during unidirectional yarn drawing. In large-scale textile production, it can significantly improve production efficiency. At the same time, there is no need to frequently change the starting position and direction of the yarn, which greatly shortens the time for yarn replacement and preparation, thereby increasing the winding output per unit time, making full use of the working time of the machine, avoiding idle waiting that may occur during unidirectional yarn drawing, thereby significantly improving the output per unit time, and at the same time, bidirectional yarn drawing reduces the time interval between yarn replacement and restarting.

[0012] In the present invention, when the device is used, the specific bidirectional rotation method is that when the rotating ring rotates, the rotating disc is driven to rotate. During the rotation, the limiting triangle blocks inside the two rotating discs are in a symmetrical mirror state with the connecting rod. When the rotating ring rotates, the two rotating discs can be prompted to rotate in both directions. When one rotating disc rotates clockwise, the other rotating disc can rotate counterclockwise, thereby releasing the yarn, so that the device has higher stability and flexibility.
