In the first embodiment, since the winding of the capacitor is that the winding pins 25 of the first winding assembly 21 and the second winding assembly 41 are coaxially contacted to perform winding, the length and the processing requirement of the capacitor can be met, and when the capacitor is drawn, the unidirectional drawing is performed, that is, the first drawing mechanism 1 or the second drawing mechanism 5 is operatively drawn and pushed back to the winding column 24, so that the discharging of the capacitor can be realized.
In the second embodiment, the length and the processing requirement of the capacitive part are that when the needle is drawn, the two-way needle drawing is performed, namely, the first needle drawing mechanism 1 and the second needle drawing mechanism 5 draw the winding column 24 simultaneously, in the embodiment, the smoothness requirement on the winding needle 25 is higher, and when the static friction force between the paper tape and the foil tape of the capacitive part and the winding needle 25 is smaller, the capacitive part can be rapidly fed when the two-way needle drawing is performed simultaneously; only the transmission cam block 67 needs to be replaced by the transmission mechanism 6, so that the second needle withdrawing mechanism 5 withdraws needles simultaneously when the first needle withdrawing mechanism 1 withdraws needles, and bidirectional simultaneous needle withdrawing is realized.
In view of the above, the present invention has the above-mentioned excellent characteristics, so that it can be used to improve the performance and practicality of the prior art, and is a product with great practical value.
The foregoing is merely exemplary of the present invention, and those skilled in the art should not be considered as limiting the invention, since modifications may be made in the specific embodiments and application scope of the invention in light of the teachings of the present invention.
