[0015] It should be particularly noted that when a certain element is described as being "fixed to, connected to or communicated to" another element, it can be directly fixed, connected or communicated to the other element, or indirectly fixed, connected or communicated to the other element through other intermediate connecting elements.

[0016] Unless otherwise defined, all the professional terms used in the following are the same as the meanings commonly understood by the skilled in the art. The professional terms used in the present application are only for the purpose of describing the specific embodiments, and are not intended to limit the protection scope of the present application. EMBODIMENT

[0017] As Figure 2 shown in the figure, an electrolytic paper 6 feeding device of an aluminum electrolytic capacitor pin winding machine, comprising a feeding table 1, a pressure roller assembly and a pressure piece 3; the feeding table 1 is provided with a feeding groove 211, and the electrolytic paper 6 passes through the feeding groove 211. The pressure roller assembly comprises a pressure roller 21 and a connecting assembly 22, the pressure roller 21 is connected to the rack 4 through the connecting assembly 22, and the pressure roller 21 presses the electrolytic paper 6 at one end of the feeding groove 211 of the feeding table 1.

[0018] In the embodiment, the feeding roller 5 of the electrolytic paper 6 is arranged on the frame 4 at the feeding end of the feeding table 1, and the electrolytic paper 6 enters the feeding groove 211 of the feeding table 1 after passing through the feeding roller 5.

[0019] In the embodiment, the connecting assembly 22 comprises a second rotating shaft 221, a connecting block 223222 and a spring. One end of the connecting block 223222 is connected to the frame 4 through a third rotating shaft 224, and the other end is connected to the pressing roller 21 through the second rotating shaft 221. The middle part of the connecting block 223222 is connected to the frame 4 through the spring, so that the pressing roller 21 on the second rotating shaft 221 presses the electrolytic paper 6 in the feeding groove 211 of the feeding table 1. With the movement of the electrolytic paper 6, the pressing roller 21 also rotates together, so that the electrolytic paper 6 is not easily scratched. The pressure of the pressing roller 21 on the electrolytic paper 6 in the feeding groove 211 is realized by the action of the spring. In the embodiment, a soft rubber ring 23 is arranged on the pressing roller 21. In this way, the damage of the pressing roller 21 to the electrolytic paper 6 can be reduced.

[0020] In the embodiment, the electrolytic paper 6 passing through the feeding roller 5 is not uniform in speed. When the speed of the electrolytic paper 6 passing through the feeding roller 5 is too slow, the tension of the electrolytic paper 6 during winding will be too large, and the electrolytic paper 6 may be separated from the feeding groove 211 of the feeding table 1 due to the tension. At this time, the pressing roller 21 is needed to limit the electrolytic paper 6 in the feeding groove 211. When the speed of the electrolytic paper 6 passing through the feeding roller 5 is too fast, too much electrolytic paper 6 is fed into the feeding groove 211 and cannot be digested in time, and the electrolytic paper 6 is easy to run out of the feeding groove 211, thereby causing deviation. Under the action of the pressing roller 21, too much electrolytic paper 6 is limited between the pressing roller 21 and the feeding roller 5, so that the electrolytic paper 6 passing through the pressing roller 21 is always limited in the feeding groove 211.

[0021] In the embodiment, the pressing piece 3 is connected to the frame 4 through a first rotating shaft 31. The pressing piece 3 presses the electrolytic paper 6 at the discharging end of the feeding table 1 by its own gravity. The first rotating shaft 31 is arranged at the upper part of the pressing piece 3 to ensure that the end is drooping. The end of the pressing piece 3 is arranged in a circular arc shape, which can reduce the damage to the electrolytic paper 6. In the embodiment, the pressing piece 3 presses the electrolytic paper 6 during winding by its own gravity, thereby ensuring the winding tension of the electrolytic paper 6. Figure 1 Compared with the conventional electrolytic paper 6 feeding device as shown in the figure, the pressure of the pressing piece 3 on the electrolytic paper 6 in the present application is smaller, and the electrolytic paper 6 is not easy to scratch. Figure 1The electrolytic paper 6 feeding device shown, when the core package is larger, the angle of the electrolytic paper 6 wound into the core package and the electrolytic paper 6 in the feeding groove 211 will be smaller, at this time the electrolytic paper 6 will push the pressure piece 3 to rotate, because the pressure piece 3 of the traditional electrolytic paper 6 feeding device has a spring, at this time the pressure of the pressure piece 3 on the electrolytic paper 6 will be larger, thus easily scratching the electrolytic paper 6. In the embodiment, even if the core package is larger, the pressure of the pressure piece 3 on the electrolytic paper 6 is smaller than the gravity of the pressure piece 3, the influence on the electrolytic paper 6 is smaller, thus not easily scratching the electrolytic paper 6.

[0022] In the embodiment, the setting of the pressure roller 21 enables the electrolytic paper 6 entering the feeding table 1 to pass in the feeding groove 211 flatly, the phenomenon of the electrolytic paper 6 running out of the feeding groove 211 will not occur; thus the pressure of the pressure piece 3 on the electrolytic paper 6 at the end of the feeding groove 211 can be reduced, using the gravity of the pressure piece 3 to push against the electrolytic paper 6 is enough, thus reducing the probability of the electrolytic paper 6 being scratched by the pressure piece 3.
