[0041] The present application is further described in detail below in conjunction with the accompanying drawings.

[0042] See also Figure 1 As shown, a winding mechanism for a loom is shown, which is used to wind the silk thread wound on the pay-off drum 101 onto multiple bobbin cores 100, which includes a machine base 1, on which a pay-off assembly 2, a feeding assembly 3, a winding assembly 4 and a wire cutting assembly 5 are arranged.

[0043] In this embodiment, the winding assembly 4 includes a first winding post 41 and a second winding post 42 which are coaxially arranged. The first winding post 41 and the second winding post 42 extend in the horizontal direction respectively and can rotate around their own axis directions respectively. A winding gap for accommodating the bobbin 100 is formed between the first winding post 41 and the second winding post 42. The second winding post 42 can move in a direction close to or away from the first winding post 41 and press the bobbin 100 against the first winding post 41. The winding assembly 4 also includes a first driving module 43 for driving the second winding post 42 to rotate and a second driving module 44 for driving the second winding post 42 to move. The first driving module 43 is a motor, and the second driving module 44 is a cylinder.

[0044] The pay-off assembly 2 is located above the winding gap, and is used to unwind the silk thread on the pay-off reel 101 through the winding gap; the loading assembly 3 is located on the side of the winding gap, and is used to transport the bobbin 100 into the winding gap; the wire cutting assembly 5 is located below the winding gap, and is used to cut the silk thread and clamp the free end of the silk thread.

[0045] When winding, the bobbin 100 is transported to the winding gap through the feeding assembly 3, and then the second winding post 42 moves and presses the bobbin 100 against the first winding post 41, and then the unwinding assembly 2 unwinds the wire through the winding gap, and the second winding post 42 rotates and drives the bobbin 100 to rotate, and the wire is wound on the bobbin 100 during the rotation of the bobbin 100. After the winding is completed, the wire cutting assembly 5 cuts the wire, and then the bobbin 100 is unloaded. In this way, the rolled wire can be wound on the bobbin 100 with the cooperation of the unwinding assembly 2, the feeding assembly 3, the winding assembly 4 and the wire cutting assembly 5, which greatly improves the winding quality and winding efficiency.

[0046] In this embodiment, the two ends of the bobbin 100 have core holes 1001 respectively, and the first winding post 41 and the second winding post 42 are respectively provided with winding rods 45 for inserting into the core holes 1001. The two ends of the bobbin 100 can be respectively sleeved on the two winding rods 45, which effectively prevents the bobbin 100 from falling out of the winding gap during the winding process, thereby improving the winding stability.

[0047] In this embodiment, the pay-off assembly 2 includes a drum seat 21 for carrying the pay-off drum 101, a pay-off frame 22 arranged on the side of the drum seat 21, a wire rod 23 arranged on the pay-off frame 22 and extending downwardly in a horizontal direction, and a wire wheel 24 arranged on the wire rod 23 and rotatable around the horizontal direction. The end of the wire rod 23 in the extension direction is provided with a wire outlet portion 25, and the wire outlet portion 25 includes a rotatable wire outlet wheel 251, a horizontally arranged wire outlet plate 252, and a wire outlet hole 253 opened on the wire outlet plate 252. The rotation axis of the wire outlet wheel 251 is parallel to the rotation axis of the wire wheel 24, and the wire outlet hole 253 is located below the wire outlet wheel 251. After the silk thread is unwound from the pay-off drum 101, it can pass through the wire wheel 24, the wire outlet wheel 251 and the wire outlet hole 253 in sequence. Through the guidance of the wire wheel 24 and the wire outlet wheel 251, not only can the silk thread be prevented from interfering with the machine base 1, but also the stability of the pay-off is effectively improved.

[0048] In this embodiment, the wire cutting assembly 5 includes a rotating shaft (not shown in the figure), two cutters 51 respectively connected to the rotating shaft, and a driving unit 52 for driving the two cutters 51 to rotate. The rotation axis of the cutter 51 extends in the vertical direction. The front end of the cutter 51 has a blade 511, and a cutting gap is formed between the two blades 511. The cutting gap is located directly below the winding gap. The driving unit 52 can drive the two cutters 51 to rotate, so that the two blades 511 can be relatively closed and cut the silk thread, which is convenient for unloading the bobbin 100 that has been wound; at the same time, the two blades 511 can clamp the free end of the silk thread, which is convenient for winding the silk thread on the new bobbin 100.

[0049] In this embodiment, the driving unit 52 includes two driving wheels 521 arranged side by side and movable in a direction close to or away from the cutting gap, and a third driving module 522 for driving the two driving wheels 521 to move. The arrangement direction of the two driving wheels 521 is perpendicular to the moving direction thereof. A driving gap is formed between the two driving wheels 521, and the two cutters 51 are accommodated in the driving gap. The two driving wheels 521 can continuously squeeze the two cutters 51 during their moving stroke. When the two driving wheels 521 squeeze the two blades 511, the two blades 511 are relatively closed and cut the silk thread. When the two driving wheels 521 are separated from the two blades 511, the two blades 511 can be relatively separated, which can effectively improve the cutting accuracy and cutting efficiency of the cutter 51.

[0050] The cutter 51 has a handle 512 at the rear end, and the two handles 512 are bent in directions away from each other, and the two driving wheels 521 can respectively press against the two blades 511 and the two handles 512 during their respective movement strokes. The two driving wheels 521 can realize the opening and closing control of the two blades 512 by squeezing the two blades 511 and the two handles 512, thereby effectively improving the cutting accuracy of the cutter 51.

[0051] In this embodiment, the third driving module 522 includes a sliding plate 5221 which is movably arranged in a direction close to or away from the cutting gap, and a driving member 5222 for driving the sliding plate 5221 to move. The driving member 5222 is a cylinder, and two driving wheels 521 are respectively arranged at the two ends of the sliding plate 5221. The winding mechanism also includes a wire pushing assembly 6 connected to the sliding plate 5221. The wire pushing assembly 6 includes a wire pushing seat 61 and a wire pushing rod 62 arranged on the wire pushing seat 61 in a horizontal direction. The wire pushing rod 62 extends along the moving direction of the driving wheel 521. The end of the wire pushing rod 62 has a wire pushing portion 63, and the wire pushing portion 63 is located between the wire unwinding assembly 2 and the winding gap. The wire pushing portion 63 is provided with a wire pushing groove 64 for the silk thread to pass through, and the length direction of the wire pushing groove 64 is parallel to the length direction of the wire pushing rod 62.

[0052] The wire pushing portion 63 can move synchronously with the driving wheel 521 and push and pull the wire, which is not only convenient for winding, but also can prevent the wire from interfering with the bobbin 100 output from the feeding channel 32. Specifically, when the bobbin 100 reaches the winding gap, the wire pushing portion 63 pushes the wire toward the first winding post 41, and the wire can be wound on the bobbin 100 along the direction from the first winding post 41 to the second winding post 42 during winding; after winding, the bobbin 100 is unloaded, and the wire pushing portion 63 can pull the wire toward the second winding post 42 to prevent the wire from blocking the subsequent bobbin 100 and affecting the bobbin 100 from entering the winding gap.

[0053] In this embodiment, the feeding assembly 3 is located on one side above the winding assembly 4, and includes a vibrating feeding tray 31 and a feeding channel 32. The two ends of the feeding channel 32 have first channel openings, one of which is connected to the outlet of the vibrating feeding tray 31, and the other first channel opening is located in the winding gap.

[0054] The feeding assembly 3 further includes two feeding rods 33 arranged vertically and parallel to each other, and the feeding channel 32 is formed between the two feeding rods 33. Each feeding rod 33 extends downwardly along the horizontal direction. A wheel groove 1002 is provided around the side of the bobbin 100, and the two feeding rods 33 are respectively embedded in the opposite sides of the wheel groove 1002. In this way, the bobbin 100 can move smoothly under the limit guidance of the two feeding rods 33, which effectively improves the feeding stability of the bobbin 100 and prevents the bobbin 100 from falling during the feeding process.

[0055] In this embodiment, the winding mechanism further includes a discharge channel 7 opened in the machine base 1, the discharge channel 7 is inclined and has second channel openings at both ends, one of the second channel openings is opened below the winding gap, and the other second channel opening is opened at the side of the machine base 1. The bobbin 100 can be discharged outward along the inclined discharge channel 7, which is convenient for unloading the bobbin 100 after winding.

[0056] The implementation principle of a winding mechanism in the embodiment of the present application is:

[0057] The bobbin 100 is transported to the winding gap by the loading assembly 3, and then the second winding post 42 moves and presses the bobbin 100 against the first winding post 41, and then the unwinding assembly 2 unwinds the silk thread through the winding gap, and the second winding post 42 rotates and drives the bobbin 100 to rotate, and the silk thread is wound on the bobbin 100 during the rotation of the bobbin 100. After the winding is completed, the wire cutting assembly 5 cuts the silk thread, and then the bobbin 100 is unloaded through the discharge channel 7.
