When winding is required, the bow tie is placed near the clamping center. The gripping mechanism 300 grips the wire extending from the lead-out end 2321 and stops at the clamping position. The driving assembly 210 then rotates the hollow tube 230, thereby causing the wire to be wound around the bow tie. The coordination of the winding mechanism 200 and the gripping mechanism 300 enables automated bow tie winding, thereby improving automation and production efficiency.
[0077] Explanatoryally, the clamping center refers to the central position where the clamping mechanism 300 clamps the wire.

A blade portion 322 and a clamping portion 323 are formed on one end of the fixed head 320 facing the winding mechanism 200. The blade portion 322 is located on one side of the cutter head through-hole 321 in the radial direction, and the clamping portion 323 is located on the other side of the cutter head through-hole 321 in the radial direction; the telescopic hook knife 330 is provided at the output end of the telescopic driving source 310 and is telescopically provided in the cutter head through-hole 321.

The material hooking position is located on the side of the clamping position facing the winding mechanism 200. The hook knife head 331 is configured to hook and pull the wire to be clamped at the material hooking position. When the hook knife head 331 moves from the material hooking position to the clamping position, the hook knife head 331 and the blade portion 322 intersect to form a shear cut to cut the passing wire, and cooperate with the clamping portion 323 to form a clamping center to clamp the passing wire. Through the above structural design, the clamping mechanism 300 has the functions of clamping, cutting, and hooking wires. The cutting function is realized by the interlaced movement of the hook head 331 and the blade portion 322 to form a shear cut for cutting the wire passing through. The wire hooking function is realized by the telescopic drive source 310 driving the hook head 331 to move back and forth between the clamping position and the hooking position, and the hook head 331 hooks and pulls the wire to be clamped at the hooking position; the clamping function is realized by the hook head 331 moving from the hooking position to the clamping position, and cooperating with the clamping portion 323 to form a clamping center to clamp the wire passing through.

Specifically, the assembly further includes an air cylinder connected to the air blowing pipe 241 for blowing air.

[0083] In some embodiments, reference Figures 1-9The winding device of the knotting machine also includes a frame 400, a first wire clamp 500, a second wire clamp 600, a swing motor 700, a tightening swing arm 800, and a wire storage swing arm 1000; the first wire clamp 500 is arranged on the frame 400 and is located downstream of the wire feeding mechanism 100, and the first wire clamp 500 is configured to guide and clamp the wire passing through the first wire clamp 500; the second wire clamp 600 is arranged on the frame 400 and is located downstream of the first wire clamp 500, and the second wire clamp 600 is configured to guide and clamp the wire passing through the second wire clamp 600; the swing motor 700 is arranged on the frame 400; one end of the tightening swing arm 800 is rotatable on the frame 400 through the rotating shaft 900, and the other end of the tightening swing arm 800 is opened A first wire threading hole 810 and a third wire threading hole 820 are provided, which are arranged at intervals. The swing motor 700 is connected to the tightening swing arm 800 in a transmission manner to drive the tightening swing arm 800 to swing back and forth between the wire pulling position and the tightening position; one end of the wire storage swing arm 1000 is rotatably connected to the frame 400 through the rotating shaft 900, and the wire storage swing arm 1000 can swing relative to the tightening swing arm 800, and the other end of the wire storage swing arm 1000 is provided with a second wire threading hole 1100; wherein, a wire storage space is formed between the first wire clamp 500 and the second wire clamp 600, and the first wire threading hole 810, the second wire threading hole 1100 and the third wire threading hole 820 are located in the wire storage space and are configured to allow the wire between the first wire clamp 500 and the second wire clamp 600 to pass through in sequence.
[0084] Specifically, the structures of the first clamp 500 and the second clamp 600 can be the same. Take the first clamp 500 as an example. Figure 3 The first clamping device 500 includes a clamping cylinder 510, a first clamping disc 520, a second clamping disc 530, and a compression spring 540. The telescopic rod of the clamping cylinder 510 is connected to the compression spring 540, and the first clamping disc 520 is fixedly connected to the compression spring 540. The second clamping disc 530 can be fixed to the frame 400 or the main body of the clamping cylinder 510. The first clamping disc 520 and the second clamping disc 530 are separated to form a clamping space. When the clamping cylinder 510 drives the telescopic rod to extend, the first clamping disc 520 and the second clamping disc 530 can move away from each other. When the clamping cylinder 510 drives the telescopic rod to shorten, the first clamping disc 520 and the second clamping disc 530 can abut against each other to clamp the wire passing through.
[0085] During operation, the wire drawn out by the wire feeding mechanism 100 passes through the first wire clamp 500, the first threading hole 810, the second threading hole 1100, the third threading hole 820, and the second wire clamp 600 in sequence, and is then introduced into the introduction end 2311 of the hollow tube 230, led out through the lead-out end 2321 of the hollow tube 230, and clamped by the clamping mechanism 300. The bow placed in the clamping position is then wound through the winding mechanism 200. Each winding requires a certain length of wire, and the wire clamped by the clamping mechanism 300 needs to be kept in a taut state during winding.
[0086] Therefore, a first wire clamp 500, a second wire clamp 600, a swing motor 700, a tightening swing arm 800, and a wire storage swing arm 1000 are added. A certain length of wire can be stretched between the first threading hole 810, the second threading hole 1100, and the third threading hole 820 as a reserve wire for subsequent winding.
[0087] For example, when it is necessary to store the wire, the first wire clamp 500 loosens the wire, the second wire clamp 600 clamps the wire, and the swing motor 700 drives the tightening swing arm 800 to swing from the tightening position to the wire pulling position. The tightening swing arm 800 and the wire storage swing arm 1000 both move to the wire pulling position, thereby pulling out the wire led out by the wire feeding mechanism 100; then, the swing motor 700 drives the tightening swing arm 800 to move from the wire pulling position to the tightening position, and the wire storage swing arm 1000 stops at the wire pulling position. The first clamp 500 and the second clamp 600 cooperate with each other to tighten the wire pulled into the wire storage space. When winding the bow, the first clamp 500 clamps the wire and the second clamp 600 loosens the wire, so that the wire in the wire storage space is drawn into the introduction end 2311 of the hollow tube 230. The wire in the wire storage space is consumed and becomes less and less. As the wire in the wire storage space is consumed, the wire storage swing arm 1000 is pulled by the wire and moves closer to the tightening swing arm 800 in the tightening position, thereby completing a round of winding consumption for a bow. Then, the next round of wire storage action begins, as described above.

[0090] Specifically, for the structures of the first half ring 4600 and the second half ring 4700. In some embodiments, reference Figure 7-Figure 9The first half ring 4600 includes a first half ring portion 4620 with a first half ring groove 4610 and a first straight rod portion 4630 connected to the first half ring portion 4620; the first straight rod portion 4630 is coaxially fixedly connected to the first gear 4400, and the axis of the first half ring portion 4620 is perpendicular to the axis of the first gear 4400.

The first and second half rings 4600 and 4700 are fixedly connected, and the axis of the second half ring portion 4720 is perpendicular to the axis of the second gear 4500. Then, through the transmission of the slider 4300, the first gear 4400, the second gear 4500 and the cooperation of the eccentric adapter 4800, the deflection rod 4900 and the arc slide 410, the first half ring 4600 and the second half ring 4700 can, on the one hand, make a linear motion along a direction parallel to the first axis X, and on the other hand, make the first half ring 4600 and the second half ring 4700 rotate around their corresponding first straight rod portion 4630 and second straight rod portion 4730 respectively.
[0091] More specifically, refer to Figure 7-Figure 9 The arc-shaped slide 410 can be an arc-shaped hole structure. Taking the straight track formed by the axis of the first gear 4400 moving in a direction parallel to the first axis X as a reference, the arc-shaped slide 410 is located on one side of the straight track, and the straight track and the tangent line of the arc-shaped slide 410 are on the same side, that is, the arc-shaped recess formed by the arc-shaped slide 410 faces away from the straight track.
[0092] The specific process of winding, bundling and knotting is as follows:
[0093] First, the first half ring 4600 and the second half ring 4700 are first leaned against the avoidance position, and the winding mechanism 200 is first wound on the bow knot located near the clamping position to complete several turns of preliminary winding.
[0094] Then, the first half ring 4600 and the second half ring 4700 move from the avoidance position to the winding position and stop at the winding position. The winding mechanism 200 winds one circle on the support ring groove formed by the cooperation of the first half ring 4600 and the second half ring 4700 to complete the second step of winding, also known as the second step of hanging wire.
[0095] Furthermore, the first half ring 4600 and the second half ring 4700 are moved from the winding position to the avoidance position and parked at the avoidance position, and at the same time, the winding mechanism 200 is used to wind one circle around the bow tie, completing the third winding step.
[0096] In another step, the first half ring 4600 and the second half ring 4700 move from the avoidance position to the off-line position and stop at the off-line position. At this time, the first half ring 4600 and the second half ring 4700 are in an approximately folded state, so that the coil formed by the second hanging step is separated from the first half ring 4600 and the second half ring 4700; for explanation, the folded state can be understood with reference to the accompanying drawings, that is, the first half ring 4600 and the second half ring 4700 are folded in half with the center line between the two (the imaginary line extending in the vertical direction in the figure) as the folding line, and then present an approximately folded state.
[0097] Finally, while returning the first half ring and the second half ring 4700 to the avoidance position, the wire introduced into the introduction end 2311 is pulled back by tightening the wire pulling action of the swing arm 800 and the knotting tightening assembly 5000, thereby making the coil formed by the second step of hanging the wire smaller and finally wrapped around the bow, and completing the knotting.
[0098] In some embodiments, reference Figure 1-Figure 3 The knotting and tightening assembly 5000 includes a knotting and tightening drive source 5100 and a wire pulling member 5200. The knotting and tightening drive source 5100 is disposed on the frame 400; the wire pulling member 5200 is disposed at the output end of the knotting and tightening drive source 5100, and the wire pulling member 5200 is located upstream of the introduction end 2311 and downstream of the second wire clamp 600; wherein, the knotting and tightening drive source 5100 is configured to drive the wire pulling member 5200 to reciprocate between a pulling position and an avoidance position, and the wire pulling member 5200 is configured to move from the avoidance position to the pulling position to pull back the wire introduced into the introduction end 2311 to tighten the wire, and the wire pulling member 5200 is further configured to release the pulling on the wire when moving from the pulling position to the avoidance position. The knotting and tightening driving source 5100 may be a linear cylinder, and the wire pulling member 5200 may be a rod with a threading hole. The wire passes through the threading hole, and the linear cylinder drives the wire pulling member 5200 by telescoping to thereby pull the passed wire.
[0099] How does the slider driving source 4100 drive the slider 4300 of the winding hanging ring assembly 4000? In some embodiments, reference Figure 1-Figure 3 and Figure 7-Figure 9 Slider drive source 4100 includes a disk 4110, a ring adapter 4120, and a swing motor 700. Disk 4110 is connected to the output shaft of swing motor 700, with the axis of disk 4110 parallel to but not coaxial with the output shaft of swing motor 700. Ring adapter 4120 defines a circular hole 4121 into which disk 4110 is rotatably inserted. Ring adapter 4120 includes a transfer rod 4122, which is hingedly connected to slider 4300 to drive the slider 4300 to slide via swing motor 700. Using swing motor 700 to provide kinetic energy allows for multiple uses of a single device, reducing costs.
[0100] Further, in some embodiments, reference Figure 2 The wire feeding mechanism 100 may include a wire feeding roller 110, a wire conductor hole plate 120, a wire conductor post 130, and a wire compression spring respectively arranged on the frame 400. The wire feeding roller 110 can be rotatably inserted into the winding drum, and the wire of the winding drum is led out and passes through the wire conductor hole plate 120 and the wire conductor post 130, and then led to the first wire clamp 500. The wire between the first wire clamp 500 and the wire conductor post 130 is compressed by the wire compression spring, which can ensure the stable feeding of the wire led to the first wire clamp 500.

In order to make the description concise, not all possible combinations of the various technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

While the description is relatively specific and detailed, it should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention.
