For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1-4 , in this embodiment, a continuous wire feeding mechanism includes a support frame 11 and a positioning table 16 arranged on one side of the support frame 11, and a wire reel 14 is installed on one side of the support frame 11;

[0028] Two groups of vertical plates 18 are connected to the top of the positioning table 16, and the tops of the two groups of vertical plates 18 are connected by a horizontal plate 19;

[0029] An installation seat 25 is installed on one side of the vertical plate 18, a wire feeding roller 27 is rotatably installed between the two installation seats 25, a second limiting roller 28 is arranged on one side of the wire feeding roller 27, both ends of the second limiting roller 28 are connected to a rotating shaft 30, a bushing 29 is sleeved outside the rotating shaft 30, an activity groove for installing the bushing 29 is arranged on the installation seat 25, and an elastic positioning member for restricting the bushing 29 to horizontally float in the activity groove is installed on the installation seat 25;

[0030] Two sets of the vertical plates 18 are internally provided with driving rollers 20. One side of the driving roller 20 is provided with a first limiting roller 21, and one side of the horizontal plate 19 is provided with an adjusting member for adjusting the position of the first limiting roller 21.

[0031] During use, the copper wire wound on the wire reel 14 is conveyed between the wire feeding roller 27 and the second limiting roller 28. The second limiting roller 28 can float horizontally. Then, the copper wire is conveyed between the driving roller 20 and the first limiting roller 21, and the position of the first limiting roller 21 can be adjusted according to the thickness of the copper wire.

[0032] As Figure 4 shown, the elastic positioning member includes a limiting plate 31 and a spring telescopic rod 33 connected to one side of the limiting plate 31. The limiting plate 31 is arranged at the opening of the movable groove far from the vertical plate 18. The limiting plate 31 is fixed on the mounting seat 25 through a fixing bolt 32. One end of the spring telescopic rod 33 away from the limiting plate 31 contacts the shaft sleeve 29.

[0033] When the second limiting roller 28 is installed between the two mounting seats 25, the shaft sleeve 29 is placed in the movable groove. After installing the limiting plate 31, the spring telescopic rod 33 can contact the shaft sleeve 29. When the shaft sleeve 29 moves in the movable groove, it will squeeze the spring telescopic rod 33, causing the second limiting roller 28 to float. During the conveying process of the copper wire, due to changes in the length of the copper wire or adjustments in the conveying speed, the situation of uneven tension may occur. The floating design can dynamically adjust the tension to prevent damage to the copper wire or affect the conveying stability due to excessive or too small tension.

[0034] As Figure 3 shown, a wire guiding plate 26 is installed on the top of the mounting seat 25; it is used for the copper wire to pass through the holes on the wire guiding plate 26 and be input between the wire feeding roller 27 and the second limiting roller 28.

[0035] As Figure 2 shown, the adjusting member includes an L-shaped plate 22 and an electric telescopic rod 24. One end of the L-shaped plate 22 is rotatably connected inside the vertical plate 18. The first limiting roller 21 is rotatably installed between the two L-shaped plates 22, and the end of the first limiting roller 21 corresponds to the middle of the L-shaped plate 22. One end of the L-shaped plate 22 far from the rotatable connection with the vertical plate 18 is fixedly connected to a fixing frame 23. One end of the electric telescopic rod 24 is rotatably connected to the horizontal plate 19, and the other end of the electric telescopic rod 24 is rotatably connected to the fixing frame 23.

[0036] When the electric telescopic rod 24 works, it can adjust the rotation of the L-shaped plate 22, thereby adjusting the position of the first limiting roller 21. The gap between the first limiting roller 21 and the driving roller 20 can be adjusted according to the thickness of the wire. At the same time, through further adjustment, the first limiting roller 21 can also cooperate with the driving roller 20 for clamping.

[0037] The spring telescopic rod 33 includes a sleeve rod and a top rod. The sleeve rod is connected to the limiting plate 31. The top rod is slidably connected to the sleeve rod and extends into the sleeve rod to be connected to a spring. When the top rod is extruded, the spring can be extruded. Under the force of the spring, the top rod can slide towards the side away from the sleeve rod.

[0038] As Figure 1 shown, a fixing plate 12 is installed on one side of the support frame 11 close to the wire reel 14. A bent pipe 13 is installed on the fixing plate 12. The copper wire passes through the bent pipe 13.

[0039] A wire guiding assembly 15 is installed on one side of the support frame 11. A wire cutting assembly 17 is provided at the bottom of the positioning table 16. It is installed in cooperation with the mechanism for use in a carbon brush molding machine.

[0040] As Figure 2 shown, a wire seat 34 is installed at the bottom of the positioning table 16, which is used for the output of the copper wire.

[0041] The working principle of the present utility model is as follows: The copper wire wound on the wire reel 14 is conveyed between the wire feeding roller 27 and the second limiting roller 28. When the second limiting roller 28 is installed between two sets of mounting seats 25, the bushing 29 is placed in the movable slot. After installing the limiting plate 31, the spring telescopic rod 33 can contact the bushing 29. When the bushing 29 moves in the movable slot, it will extrude the spring telescopic rod 33, making the second limiting roller 28 float. Then the copper wire is conveyed between the driving roller 20 and the first limiting roller 21. The electric telescopic rod 24 works to adjust the rotation of the L-shaped plate 22, so as to adjust the position of the first limiting roller 21, and the gap between the first limiting roller 21 and the driving roller 20 can be adjusted according to the thickness of the wire.

[0042] The above is only the preferred embodiment of the present utility model, and it is not a limitation of the present utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still belong to the protection scope of the technical solution of the present utility model.
