Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, specifically a continuous winding device for covered yarn. Background Technology

[0002] In the production process of covered yarn, in order to ensure the continuity of production, the produced covered yarn needs to be wound into a large spool first. In subsequent processing, according to the needs of downstream manufacturers, the large spool will be unwound and rewound into smaller spools for their use. After the existing winding equipment completes the winding of a small spool, the yarn bobbin used for winding the covered yarn needs to be reinstalled. Since the replacement interval between the two yarn bobbins is short, and during the production process, one worker needs to operate multiple machines, resulting in the need to constantly move around and change yarn bobbins, which is labor-intensive. Utility Model Content

[0004] To achieve the above objectives, the present invention adopts the following technical solution: the continuous winding equipment for coated yarn includes a mounting frame, on which a reciprocating ball screw is mounted, and a servo motor for driving the ball screw to rotate is mounted on the mounting frame.

A guide unit is provided on the lower surface of the slide block, the guide unit including a bracket mounted on the lower surface of the slide block, a guide wheel mounted on the bracket, and the coated yarn passing between the guide wheel and the bracket. Two sets of winding units are mounted on the mounting frame, each winding unit including a vertical plate slidably connected to the mounting frame. The frame is threaded with bolts, the front ends of which are rotatably connected to the upright plate. Clamping blocks are rotatably connected to both the mounting frame and the upright plate.

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0018] like Figures 1-5As shown, a continuous winding device for coated yarn includes a mounting frame 2, on which a reciprocating ball screw 3 is mounted. A servo motor 4 for driving the ball screw 3 is also mounted on the mounting frame 2. Guide rods 5 are respectively mounted on the mounting frame 2 on both sides of the ball screw 3. The device also includes a slide block 6 that cooperates with the ball screw 3. The slide block 6 is slidably connected to the guide rods 5. A guide unit is provided on the lower surface of the slide block 6. The guide unit includes a bracket 7 mounted on the lower surface of the slide block 6. A guide wheel 8 is mounted on the bracket 7. The coated yarn 1 passes between the guide wheel 8 and the bracket 7. Two sets of winding units are mounted on the mounting frame 2. Each winding unit includes a vertical plate 9 slidably connected to the mounting frame 2. Bolts 10 are threadedly connected to the mounting frame 2, with the front end of the bolts 10 connected to the vertical plate. 9. A rotatable connection is made between the mounting frame 2 and the upright plate 9. A clamping block 11 is rotatably connected to both the mounting frame 2 and the upright plate 9. A groove 12 is provided on one side of the clamping block 11. A slot 13 is provided on the inner side wall of the groove 12. An electrically excited brake motor 14 for driving the clamping block 11 to rotate is provided on the mounting frame 2. The mounting frame 2 also includes a spool for winding the covering yarn 1. The spool includes two clamps 15. Side tubes 16 are provided at both ends of the two clamps 15. A protrusion 17 is provided on the surface of one side tube 16. A slot 18 is provided on the surface of the other side tube 16. A locking block 19 that cooperates with the slot 13 is provided on the outer surface of the side tube 16. A blade 20 is provided on the mounting frame 2. The blade 20 is located between the two sets of winding units. The blade of the blade 20 is inclined toward the winding unit farthest from the guide wheel 8.

[0019] Before splitting the large spool into smaller spools, two spools for winding the covering filament 1 are first installed between the two clamps 11 on the upright plate 9 and the mounting bracket 2. Specifically, the protrusion 17 on one side spool 16 is aligned with the slot 18 on the other side spool 16, and the protrusion 17 is pressed into the slot 18. Through the pressing and friction between the protrusion 17 and the slot 18, the two clamps 15 can be connected together. After the two clamps 15 are connected, there is a certain gap between them, which is about 5mm-10mm. This gap allows the covering filament 1 to pass through the spool. After the spool assembly is completed, the bolt 10 is rotated to connect the bolt 10 to the mounting bracket 2 via a thread and to the upright plate 9 via a rotational connection. Increase the distance between the two clamping blocks 11. When the distance between the two clamping blocks 11 is sufficient to insert the wire drum between the two clamping blocks 11, the bolt 10 stops rotating. Then, align the clamping block 19 at one end of the wire drum with the slot 13 on the clamping block 11 and insert it into the slot 13. Then, align the clamping block 19 at the other end of the wire drum with the slot 13 on the other clamping block 11. Then, rotate the bolt 10 in the opposite direction to push the vertical plate 9 to move, so that the clamping block 19 on the wire drum can enter the slot 13 in the clamping block 11 on the vertical plate 9. When the distance between the two clamping blocks 11 reaches a certain distance, the vertical plate 9 can no longer move. At this time, the wire drum can be stably clamped and fixed between the two clamping blocks 11. The electrically excited brake motor 14 can drive the wire drum between the two clamping blocks 11 to rotate at any time.

[0020] After installing the two spools, first pull out one end of the spool mounted on the external unwinding device. The covering wire 1 released from the spool passes through the external tensioning device, then through the guide wheel 8, and passes through the gap in the spool closest to the guide wheel 8. Then, it passes through the gap in the other spool and is knotted onto that spool, i.e., tied to the second spool it passed through. After pulling the covering wire 1, first start the electrically excited brake motor 14, which is furthest from the guide wheel 8, to rotate the corresponding spool. As the spool rotates, the covering wire 1 is wound around its outer surface. Simultaneously, the servo motor 4 starts, driving the reciprocating screw to rotate. Through the cooperation of the slide block 6 and the reciprocating screw, and the sliding connection between the slide block 6 and the guide rod 5, the slide block 6 can reciprocate, thereby driving the guide wheel 8 to reciprocate. This allows the covering wire 1 to be wound regularly around the outer surface of the spool. (Refer to the instruction manual attached.) Figure 5 As shown, the spool rotates counterclockwise when winding the covering yarn 1, and the winding covering yarn 1 never comes into contact with the blade during the winding process.

[0021] The electric excitation brake motor 14, which is closest to the guide wheel 8, is not powered. At this time, the output end of the electric excitation brake motor 14 can rotate freely. That is, when the covered wire 1 passes the wire drum closest to the guide wheel 8, the covered wire 1 can drive the wire drum to deflect at a certain angle, thereby reducing the friction when the covered wire 1 passes the wire drum.

[0022] When the electrically excited brake motor 14 is not powered on, its output terminal can rotate freely. When it is powered on but no rotation signal is given, its output terminal cannot rotate. When a rotation signal is given, its output terminal can rotate under control. The electrically excited brake motor 14 can also be replaced by a motor equipped with an electromagnetic brake.

[0023] When the spool furthest from the guide wheel 8 finishes winding the covering yarn 1, the electrically excited brake motor 14 associated with that spool is de-energized, and simultaneously another electrically excited brake motor 14 starts, driving the associated spool to rotate clockwise. The rotation of the spool causes the covering yarn 1 passing through its gaps to wind around its surface. Simultaneously, because the other electrically excited brake motor 14 is de-energized, when the spool closest to the guide wheel 8 begins winding the covering yarn 1, in addition to the covering yarn 1 released from the unwinding device being continuously wound by the current spool, a portion of the covering yarn 1 from the previous spool that has already finished winding will also be wound by the current spool. Since the spool furthest from the guide wheel 8 rotates counter-clockwise when winding the covering yarn 1, when the spool closest to the guide wheel 8 winds the covering yarn 1, it will drive the other spool to rotate clockwise. The coated yarn 1 released from the spool that has finished winding can move downwards by one end. When the coated yarn 1 moves downwards, it can rub against the blade 20 and be cut by the blade 20, but the pressure is small and it will not cut the coated yarn 1. When the friction between the coated yarn 1 wound on the spool closest to the guide wheel 8 and the spool is large, the electrically excited brake motor 14 farthest from the guide wheel 8 starts to be powered on, but its output end does not rotate. Therefore, the spool that cooperates with it will also stop rotating. Since the blade 20 will scratch the surface of the coated yarn 1, when the spool farthest from the guide wheel 8 stops rotating, the other spool continues to rotate. Therefore, the coated yarn 1 between the two spools that has been scratched by the blade 20 will be stretched and broken, so that the coated yarn 1 on the spool farthest from the guide wheel 8 cannot continue to be transferred to the previous spool.

[0024] The external unwinding equipment is not powered; the power to move the traction covering yarn 1 is provided by two electrically excited brake motors 14.

[0025] The spool located in the middle can take out a roll of covered yarn from another spool with a length of less than 1.5m.

[0026] When inserting the yarn spool into textile or other equipment, the single wrapped yarn 1 passing through the yarn spool must be cut first to prevent the yarn spool from being unable to be inserted into the equipment.

[0027] The start and stop of the servo motor 4, as well as the start, stop, power-on and power-off actions of the electrically excited brake motor 14, can all be controlled by the program set by the PLC controller.

[0028] Between the external unwinding equipment and the tensioning device, there is also a sensor for calculating the length of the covering yarn 1. When the covering yarn 1 wound on the yarn spool reaches a certain length, the PLC controller automatically switches to another yarn spool to continue winding the covering yarn 1. When both yarn spools have finished winding the covering yarn 1, all motors stop, and the yarn spools are removed and replaced with new ones.

[0029] Furthermore, when the winding unit furthest from the guide wheel 8 winds up the covering yarn 1 through the yarn drum, the electrically excited brake motor 14 in another winding unit is de-energized, so as to adjust the position of the unwound yarn drum, reduce the friction between the covering yarn 1 and the non-rotating yarn drum, and prevent the covering yarn 1 from breaking.

[0030] Furthermore, the guide wheel 8 is provided with an annular arc groove for accommodating the covering wire 1, so that the covering wire 1 can stay in the guide wheel 8 more stably and continuously.

[0031] Furthermore, the two ends of the arc-shaped groove in the guide wheel 8 extend away from the center of the guide wheel 8 to avoid the covering wire 1 from entering between the guide wheel 8 and the bracket 7 as much as possible.

[0032] Furthermore, two sets of guide units are provided and symmetrically arranged on the lower surface of the slide block 6 to reduce the bending angle of the covering wire 1 and improve the stability of the covering wire 1 when it reciprocates.

[0033] In the description of this utility model, when rotation occurs between two components, a bearing connection is used. One component is fixedly connected to the outer ring of the bearing, and the other component is fixedly connected to the inner ring of the bearing, thereby achieving a rotational connection between the two components.

[0034] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
