Needles are usually made according to a certain shape. The needle roller material is usually collected by a wire roller before use. When making needle rollers, they need to be straightened and cut first, and the cut needle rollers need to be rounded to meet the requirements. And the needle roller rounding process is usually carried out in a large rounding cylinder, and there are great problems in loading and unloading the needle rollers. Traditional needle roller rounding is carried out by machine tools, and the needle roller loading and unloading is carried out by manual handling, which leads to extremely low production efficiency, high energy consumption, and high labor intensity. To this end, the present invention proposes a needle roller rounding and automatic feeding and unloading equipment, which uses a needle roller hopper hooking device to lift the needle roller hopper and invert the needle rollers in the hopper into the feeding and unloading plate, and then the feeding and unloading plate is extended into the needle roller rounding cylinder, tilted downward for loading, and the feeding and unloading plate is extended into the rounding cylinder for unloading when unloading. Then, a single motor can be used to drive the rounding cylinder, and the material-scraping plate can drive the roller needle, so that the roller needle falls under the action of gravity, thereby performing rounding. The roller needle rounding device adopts a bag dust collector, which can promptly handle the residual ash produced by the rounding, thereby protecting the environment. Summary of the invention

[0016] The following is a detailed description of an embodiment of the present invention. This embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation method and a specific operation process are given, but the protection scope of the present invention is not limited to the following embodiment.

[0017] Example 1

[0018] like Figure 1 and Figure 2 As shown, a needle roller rounding device includes a rounding barrel 1, characterized in that: the rounding barrel 1 is horizontally arranged, and an outer tooth 11 is arranged at the outer edge of the middle section of the rounding barrel 1 along the circumference of the rounding barrel 1, and the outer tooth 11 is connected to the driving motor to drive the rounding barrel 1 to rotate, and rolling supports 12 are arranged at both ends of the rounding barrel 1, and the needle roller rounding device also includes an ash discharge device, and the ash discharge device includes an exhaust fan 15, a dust bag 14 and an air duct 13, and the air duct 13 is connected to the rotating axis of one side of the rounding barrel 1 through a sealed bearing, and the dust bag 14 is arranged between the exhaust fan 15 and the air duct 13. Since the horizontally arranged rounding barrel 1 has supports at both ends, its aspect ratio can be much larger than that of the traditional rounding device, so it can handle more needle rollers at one time, and the outer tooth 11 arranged in the middle section can provide a balanced driving force to the rounding barrel 1, ensuring a smooth working process, and at the same time, the two ends of the rounding barrel 1 are vacated, one end is used as a feed port, and the other end can be used for ash discharge.

[0019] A lifting plate 16 is arranged in the rounding barrel 1, and the lifting plate 16 extends inwardly along the diameter direction from the inner wall of the rounding barrel 1. The stir-frying-like arrangement can help toss the rolling needle, making the rounding process smoother, and at the same time, the ash is also thrown up, so that the ash discharge device can absorb and discharge the ash.
