Embodiment 1
[0047] Figure 1 to Figure 3 It shows a specific embodiment of the motor direct-driven needle winding mechanism of the present application, which is the same as the traditional needle winding mechanism, and it also includes: an outer support frame 1, which is rotatably arranged on the outer support frame Turntable 2, rolling needle mounting seat 3, rolling needle 4 installed on the rolling needle mounting seat.
[0048] The key improvement of this embodiment is that the needle winding mechanism also includes a direct drive motor 5 connected to the turntable 2, the motor shaft 501 of the direct drive motor 5 is directly connected with the needle mounting base 3, and the direct drive motor 5 can move axially forward and backward relative to the turntable 2 (the direct drive motor 5 is connected with the turntable 2 through a sliding connection). When working, the direct-drive motor 5 is energized to run, and the motor shaft 501 rotates, thereby driving the rolling needle mounti...
Embodiment 2
[0062] Figure 4 and Figure 5 It shows the second specific embodiment of the motor direct-driven needle winding mechanism of the present application. Its structure is similar to that of Embodiment 1, and also includes the outer support frame 1, which rotates the turntable 2 arranged on the outer support frame, and rotates The rolling needle mounting seat 3 arranged on the turntable, the rolling needle 4 arranged on the rolling needle mounting seat, the pin insertion assembly (not shown in the figure) and the setting needle assembly (not shown in the figure) installed on the outer support frame , fixed on the direct drive motor 5 on the turntable 2. The motor shaft 501 of the direct drive motor 5 is directly connected with the needle rolling seat 3 .
[0063] The main difference between this embodiment and the above-mentioned first embodiment is that there are only two winding needles 4 in this embodiment, and correspondingly, there are two winding needle mounting bases 3 an...
Embodiment 3
[0066] Figure 6 and Figure 7 It shows the third specific embodiment of the motor direct-driven needle winding mechanism of the present application. Its structure is similar to that of Embodiment 1, and also includes the outer support frame 1, which rotates the turntable 2 arranged on the outer support frame, and rotates The rolling needle mounting seat 3 arranged on the turntable, the rolling needle 4 arranged on the rolling needle mounting seat, the pin insertion assembly (not shown in the figure) and the setting needle assembly (not shown in the figure) installed on the outer support frame , fixed on the direct drive motor 5 on the turntable 2. The motor shaft 501 of the direct drive motor 5 is directly connected with the needle rolling seat 3 .
[0067] The main difference between this embodiment and the above-mentioned first embodiment is that only one winding needle 4 is provided in this embodiment, and correspondingly, only one winding needle mounting base 3 and dire...
