[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] A feeding mechanism suitable for the post-processing of resistance wire, such as Figure 1-2 As shown, a roller conveyor is included, used to transport material baskets containing resistance wires. The roller conveyor comprises two horizontally and parallel frames 21. An electric roller 22 is installed in the middle between the two frames 21, and several driven rollers 23 are installed on both sides of the electric roller 22. The fixed center distance between adjacent driven rollers 23 is set to 90mm or 120mm. The electric roller 22 is connected to any two adjacent driven rollers 23 via a 3PJ multi-wedge belt 25, and any two adjacent driven rollers 23 are connected via a 2PJ multi-wedge belt 24. This arrangement can better increase friction and reduce roller slippage during transmission.

[0022] The roller conveyor also includes two support legs 11, which are bolted between the two frames 21. A connecting crossbar 14 is provided between the two support legs 11 to increase the stability of the roller conveyor. Adjustable feet 12 are also installed at the bottom of the support legs 11, and are fixed to the ground by expansion bolts 13. A control panel 27 for adjusting the speed of the electric roller 22 is also provided on the frame 21.

[0023] Two mounting seats 341 are respectively provided on both sides of the end of the conveying direction of the roller conveyor. The two mounting seats 341 are connected to the frame 21 by bolts. Each mounting seat 341 has two bearing seats 344 arranged vertically. A rotating shaft 345 is installed on the bearing seat 344, and the two ends of the rotating shaft 345 are respectively installed in the two bearing seats 344. A blocking swing arm 342 is provided at the upper end of the two rotating shafts 345. The blocking swing arm 342 is set in L shape. The rotation of the rotating shaft 345 drives the two blocking swing arms 342 to rotate into the conveying path of the roller conveyor to block the material basket, or drives the two blocking swing arms 342 to rotate away from the conveying path of the roller conveyor.

[0024] A horizontal mounting plate 36 is provided on one of the mounting bases 341. The mounting plate 36 is located below the blocking swing arm 342. A proximity switch 38 for controlling the start and stop of the roller conveyor is provided on the mounting plate 36. A photoelectric plate 32 is provided on the blocking swing arm 342 above the mounting plate 36. The rotation of the blocking swing arm 342 drives the photoelectric plate 32 to move closer to or away from the proximity switch 38, thereby controlling the start or stop of the conveying function of the roller conveyor.

[0025] A horizontal limiting plate 37 is provided on another mounting base 341, and an arc-shaped limiting groove is provided on the limiting plate 37. A vertical gripping rod 33 is fixed on the blocking swing arm 342 above the limiting plate 37, and the lower end of the gripping rod 33 extends into the limiting groove. In this embodiment, as... Figure 3 As shown, the limiting groove restricts the rotation of the grip 33, causing the blocking swing arm 342 to open and close at an angle of 28.15°.

[0026] The lower ends of the two rotating shafts 345 are connected by a linkage assembly. The linkage assembly includes two connecting plates 343, a positive thread spherical head 312, a positive thread hexagonal nut 313, a threaded rod 311, a negative thread hexagonal nut 315, and a negative thread spherical head 314. The two connecting plates 343 are respectively fixed to the lower ends of the two rotating shafts 345. The positive thread spherical head 312 and the negative thread spherical head 314 are respectively mounted on the two connecting plates 343. The positive thread spherical head 312 is provided with a positive thread hexagonal nut 313, and the negative thread spherical head 314 is provided with a negative thread hexagonal nut 315. The two ends of the threaded rod 311 are threadedly connected to the positive thread hexagonal nut 313 and the negative thread hexagonal nut 315, respectively.

[0027] like Figure 3 The diagram shows the changes in the two blocking arms 342 of the roller. Figure 3There are two sets of blocking swing arms 342, one of which is set to display the position after rotation. When the blocking swing arms 342 approach each other, the roller conveyor is in a stopped state; when the two sets of blocking swing arms 342 move away from each other, the roller conveyor is in an open state. In use, the operator stands at the end of the conveying path of the roller conveyor, located on the side close to the handle 33. The operator manually controls the handle 33, which is linked through the rotation point M2 on the rotating shaft 345, the rotation point N2 on the connecting plate 343, the threaded rod 311, the rotation point M1 on another connecting plate 343, and the rotation point N1 on another rotating shaft. Specifically, the operator manually controls the lever 33, which drives a rotating shaft 345 connected to it to rotate. The rotation of the rotating shaft 345 drives the connecting plate 343 connected to it to rotate. The rotation of the connecting plate 343 drives the orthogonal spherical head 312 to rotate. The orthogonal spherical head 312 drives the threaded rod 311 to move. The threaded rod 311 drives the reverse spherical head 314 to rotate. The reverse spherical head 314 drives another connecting plate 343 to rotate. The connecting plate 343 drives the rotating shaft 345 connected to it to rotate. The rotating shaft 345 drives the blocking swing arm 342 connected to it to rotate, ultimately achieving symmetrical movement of the two blocking swing arms 342.

[0028] In this embodiment, the passive roller 23 is a galvanized steel cylinder with a diameter of φ50×1.5, and one end has a multi-wedge pulley element. The electric roller 22 is a galvanized steel cylinder with a diameter of φ50×1.5, with a built-in 24V drive motor, which, together with the drive card of the control panel 27, controls different speeds. The support frame 11 is made of 60×40×2 rectangular tubing welded together, with a height of 800mm. The handle 33 is made of φ15mm metal rod with a length of 100-150mm, deburred and chamfered. The threaded rod 311 is designed with a milled flattened middle section for easy wrench insertion and adjustment, and has positive and negative threads on both ends for screwing into a fisheye head. The blocking swing arm 342 is welded and fixed to the rotating shaft 345.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
