Description

Technical Field

[0001] The utility model relates to the technical field of textiles, in particular to a gold and silver thread unwinding device for textiles. Background Art

[0002] Filigree refers to the fine workmanship of fine metal wires of gold, silver or silver-gilt into delicate and complex shapes. The works are either openwork or welded on a gold or silver base as a surface decoration. The metal wire can be curled, twisted or woven, and often with metal beads or fine particles. Filigree products are fully columnar and have good strength. They are widely used in computer embroidery, hand embroidery, fishing gear, trademarks, ribbons, sweaters, warp knitted fabrics, etc.

[0003] During the processing and production of gold and silver wires, it is necessary to unwind the wire wound on the cylindrical wire winding drum. In order to prevent the wire drawn out during unwinding from being squeezed and colliding with the wire wound on the end of the outer wall of the wire winding drum, causing the originally wound wire to fall off and become knotted, the patent with application number 202320912241.8 in the public technology discloses a wire unwinding device that is not easy to fall off, including a wire winding drum for winding the wire, a guiding device for changing the stretching direction of the wire, and a guide ring; the guiding device includes a circular annular guide rail and a slider hook for hooking and changing the pulling direction of the wire. Although it can solve the problem that the wires are easy to fall off at the same time and affect each other and become knotted during the unwinding process, the device still has certain minor disadvantages in actual use, such as:

[0004] 1. Because the silk thread is wound on the top of the wire winding drum in a horizontal reciprocating spiral manner, when the wound silk thread is pulled out by the slider hook, the slider hook can only perform circular motion around the wire winding drum as the center, and cannot perform horizontal motion according to the reaction force provided to the slider hook by the pulled out silk thread. When the pulled silk thread is located at both ends of the wire winding drum, the friction force between the silk thread and the slider hook is relatively large, and the probability of damaging the silk thread is relatively high; 2. In addition, in order to prevent the silk thread that is pulled out during unwinding from being squeezed and colliding with the silk thread that is not wound at the end of the outer wall of the wire winding drum, causing the originally wound silk thread to fall off and become knotted, the guide ring needs to be as coaxial as possible and away from the extension line of the axis of the wire winding drum. This will cause the entire device to occupy a larger installation space, and the requirements for the adaptation environment are relatively high. Utility Model Content

[0005] The utility model aims to provide a gold and silver yarn unwinding device for textile use, so as to solve the problem raised in the above-mentioned background technology that because the silk thread is wound on the top of the winding drum in a transverse reciprocating spiral manner, when the wound silk thread is pulled out by the slider hook, the slider hook can only perform circular motion around the winding drum as the center, and cannot perform transverse motion according to the reaction force provided to the slider hook by the pulled-out silk thread; when the pulled silk thread is located at both ends of the winding drum, the friction force between the silk thread and the slider hook is relatively large, and there is a high probability of damaging the silk thread.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] The cam is then pulled back to allow the wire to travel out of the way and out of the way before it is unwound.

The cross bar 10 can control the overall lateral length of the cross bar 10 according to the number of single-section structures required to form the whole, so as to meet the use of wire winding drums 4 of different lengths, and the end of the screw rod 20 away from the pasting plate 1 is fixedly connected with a convex ring 18, and the convex ring 18 can facilitate the application of force to the screw rod 20.

[0025] The outer wall of the sticking ring 5 is rotatably connected with a collar 16, and the collar 16 is rotatably connected with the sticking ring 5 through a ball bearing. A wire barrel 17 is inserted above one side surface of the collar 16, and the wire barrel 17 passes through the collar 16. The wire barrel 17 is fixedly connected to the penetration surface of the collar 16. A U-shaped rod 19 is inserted above the outer wall of the collar 16, and the U-shaped rod 19 is in contact with the outer wall of the cross bar 10. The U-shaped rod 19 can facilitate the wire barrel 17 to perform circular movement together with the hook 7.

[0026] During the use of the gold and silver yarn unwinding device for textiles, the operator first fixes the pasting plate 1 at a suitable position on the external equipment, and then passes the screw rod 20 through the winding drum 4 with gold and silver yarn 6 wound on the outer wall, and then connects the screw rod 20 with the cross column 2 by thread, so that the two pasting rings 5 ​​can be tightly pressed against the winding drum 4, and then the end of the gold and silver yarn is passed through the hook 7 and the guide ring 3 of the wire drum 7 in turn, and it can be pulled to realize the unwinding operation of the gold and silver yarn 6 wound on the outer side of the winding drum 4. Since the gold and silver yarn 6 is initially wound on the winding drum 4, one end of the gold and silver yarn 6 is subjected to the traction force. The gold and silver wire 6 will be straightened, and the direction in which the gold and silver wire 6 is pulled from the wire winding drum 4 until the hook is detached from the wire winding drum 4 is divergent outward toward the axis of the wire winding drum 4, and one end of the gold and silver wire 6 is constantly moving away from the wire winding drum 4 from leaving the wire winding drum 4 to the hook 7. Therefore, the line connecting the position where the gold and silver wire 6 is detached from the wire winding drum 4 to the position where the hook 7 hooks the gold and silver wire 6 will not affect the other wires still wound on the wire winding drum 4. Therefore, when the gold and silver wire 6 is detached from the wire winding drum 4, it will not squeeze the remaining gold and silver wire 6 on the wire winding drum 4, causing the gold and silver wire still left on the wire winding drum 4 to be squeezed. 6 falls off from the winding drum 4, which prevents knots from affecting the smooth unwinding. In this process, because the gold and silver wire 6 is wound on the winding drum 4 and is in a non-rotatable state, the traction force will drive the gold and silver wire 6 to fall off from the winding drum 4. The pulling force on the gold and silver wire 6 from the direction of the guide ring 3 and the supporting force of the winding drum 1 on the gold and silver wire 6 will form a force on the hook 7, the slide cylinder 8, the cross bar 10, the vertical plate 11 and the slider 14. The slider 14 is restricted in the annular groove 13, which can make the slider 14 slide in an annular shape inside the annular groove 13. At this time, during the annular movement of the slide cylinder 8 above the hook 7, it will also slide on the cross bar 10, and performs intermittent lateral movement on the outer wall of the wire 10, which can reduce the friction force between the gold and silver wire 6 and the hook 7, so that the probability of damaging the gold and silver wire 6 is significantly reduced. During this process, the wire tube 7 will be supported by the sleeve plate 16, and the wire tube 7 will act on the gold and silver wire 6. This can effectively prevent the gold and silver wire 6 from being pulled out during unwinding and the gold and silver wire 6 wound at the end of the outer wall of the winding tube 4 due to squeezing and collision, causing the wound gold and silver wire 6 to fall off and become knotted. This can be achieved without increasing the distance between the guide ring 3 and the winding tube 4, so as to reduce the requirements for adapting to the installation environment.
