[0027] In this embodiment, the transmission mechanism 4 is a conventional structure in the mechanical field. The winding drum 1 can be directly driven by a motor, or the motor drives the driving wheel to rotate. A belt is provided between the driving wheel and the winding drum 1.

The pull rod 24 can be directly driven by a cylinder, an oil cylinder or an electric cylinder, or a motor in combination with a lead screw or a slider, or other mechanical structures that can drive the pull rod to perform telescopic movement.

[0031] The winding drum 1 is provided with a plurality of wire rollers 26 along the circumferential direction, and the wire is pulled over and clamped on the wire clamp 11 to prevent the wire from running out of the wire clamp 11 during rotation.

[0032] The wire clamp 11 includes a first extrusion member 111 and a second extrusion member 112, and a winding channel with a variable gap is formed between the first extrusion member 111 and the second extrusion member 112. The wire clamp 11 also includes a positioning pin 113 and a spring 114.

The first extrusion member 111 and the second extrusion member 112 are arranged opposite to each other and the second extrusion member 112 is mounted on the winding reel 1. When the winding reel 1 rotates, the wire clamp 11 gradually moves along the length direction of the silk thread (that is, the silk thread is wound on the tassel rope, and the movements of the two are relative).

[0033] It also includes a wire hanging mechanism 3, which includes a wire pulling member 31 that can automatically or manually achieve lateral sliding and a clamping member 32 that can be automatically opened and closed, the clamping member 32 is arranged on the other side of the winding drum 1, the wire pulling member 31 is used to pull the silk thread and at least part of the silk thread is passed through the outside of the wire pulling member 31, the positions of the clamping member 32 and the wire clamp 11 constitute the starting point fixed position and the terminal hanging position of the wire pulling member 31 to pull out a section of silk thread, when the wire pulling member 31 corresponds to the starting position, the clamping member 32 clamps part of the silk thread passed through the outside of the wire pulling member 31, and when the wire pulling member 31 corresponds to the terminal hanging position, the inner end of the silk thread corresponds to the wire clamp 11.

[0034] The wire hanging mechanism 3 also includes a slide rail 33 fixed to the mounting frame, a slide plate 34 slidably connected to the slide rail 33, and a guide rod 35 installed on the slide plate 34. The slide plate 34 can reciprocate along the slide rail 33 under the drive of a power source. The wire pulling member 31 is fixed to the guide rod 35 and is provided with a threading hole 311 for the wire to pass through.

[0035] The guide rod 35 is vertically arranged and one end of the guide rod 35 is rotatably connected to the slide plate 34. The slide plate 34 is provided with a driving member 36 for driving the guide rod 35 to rotate. The driving member 36 is a pneumatic cylinder, an electric cylinder or an oil cylinder. A swing plate 4237 is fixed on the guide rod 35. One end of the swing plate 4237 is fixed to the guide rod 35, and the other end of the swing plate 4237 is connected to the driving member 36. The driving swing plate 4237 of the driving member 36 rotates and drives the wire pulling member 31 to swing back and forth.

[0036] The working principle of the wire hanging mechanism 3: after one end of the silk thread passes through the wire guide frame, at least part of it passes through the threading hole 311 of the wire pulling member 31. When the wire pulling member 31 is in a fixed position corresponding to the starting point, the clamping member 32 clamps the part of the silk thread exposed outside the wire pulling member 31. Then the wire pulling member 31 moves toward the end position to pull the silk thread. After each movement, a section of silk thread of equal length will be pulled out. The inner end of a section of silk thread is used as a fulcrum by the wire pulling member 31 and is placed on the wire clamp 11. Then the winding reel 1 performs the winding process. At this time, the clamping member 32 will loosen the silk thread, and a section of silk thread rotates with the winding reel 1 and is wound on the tassel rope at the outer end of the wire barrel 2.

[0037] The working principle of knot tying: before winding the winding drum 1, the inner end of a section of silk thread is hung on the wire clamp 11 by the wire hanging mechanism 3 and the inner end of the silk thread is fixed by the wire hanging mechanism 3, and the outer end of the silk thread is a movable end. At this time, the front end of the hanging rope member 23 is located at the rear side of the barrel head 21 and outside the movable groove 22. When the winding drum 1 is wound, at least the first circle of silk thread is wound outside the hanging rope member 23 to form a rope mouth. The hanging rope member 23 swings toward the front end of the barrel head 21 with the guide rod 35 so that the remaining silk thread is misaligned with the support surface 251 of the cutting table 25 when it is wound, or the rope mouth moves with the hanging rope so that the silk thread is misaligned with the support surface 251 of the cutting table 25 when it is wound. The surface 251 is misaligned, and the remaining silk threads slide to the front end of the tube head 21 under the guidance of the conical surface 211 of the tube head 21. As the tassel rope is gradually pulled out of the guide channel, the hanging rope member 23 swings its head and will gradually move closer to the front end of the tube head 21 to narrow the rope mouth. When the tail line is processed, the pull rod member 24 is extended, and the last circle of silk thread is wound around the outside of the pull rod member 24. The pull rod member 24 pulls the tail line (i.e. the remaining silk thread) out of the rope mouth, and finally the silk thread at the inner end of the hanging wire mechanism 3 is tightened and cut. Before tightening and cutting, the front end of the hanging rope member 23 will be completely retracted into the movable groove 22, and the rope mouth can be tightened and knotted.

[0038] The existing tassel rope manufacturing process usually takes a tassel rope of a certain length, and performs a winding process in the middle of the tassel rope, folds it in half with the winding position as the midpoint, and finally winds and knots the folded end to complete the tassel rope production. The winding mechanism of the present application can be suitable for a single winding in the middle of the tassel rope, or a secondary winding at the rear end of the folded tassel rope, and can be used on semi-automatic equipment or fully automatic tassel machine equipment.

[0039] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only preferred examples of the utility model, and are not used to limit the utility model.
