[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the scope of implementation of the present invention is not limited thereto.

[0016] like Figure 1 , 2As shown, an automatic tapered roller material feeding device of the present embodiment comprises a frame 1 arranged at an angle to a horizontal plane, the frame 1 is rotatably connected to two rollers 2 which are parallel to the frame 1, the two rollers 2 are parallel to each other and are equidistant from the frame 1, there is a gap between the two rollers 2, and mutually meshing gears are arranged between the two rollers 2, a feeding motor 3 for driving one of the rollers 2 to rotate is arranged at the higher end of the frame 1, a material guide pipe 4 for receiving the roller is arranged at the lower end of the frame 1; a material discharging motor 5 is arranged at the middle part of the frame 1 near the lower end, and a fan wheel 6 for dialing back the rollers which have not fallen between the two rollers 2 is fixed to the output shaft of the material discharging motor 5.

[0017] This embodiment is the main mechanism of the bearing roller automatic feeding machine, which is used to straighten out the tapered rollers. Specifically, after the tapered roller falls on the top of the two rollers 2, the roller will slide down along the inclined rollers 2. Because the gap between the two rollers 2 is larger than the diameter of the middle of the tapered roller and smaller than the diameter of the large end of the tapered roller, the roller will be inserted between the two rollers 2 with the small end facing downward until it leaves the rollers 2. The roller will fall into the guide tube 4 with the small end facing downward, thereby achieving the purpose of material sorting and facilitating the roller feeding during the subsequent bearing assembly.

[0018] In order to prevent the bearing roller from being stuck by the two rollers 2 and unable to slide down, the two rollers 2 rotate in opposite directions, and observing upward from the lower end of the frame 1, the roller 2 on the left rotates counterclockwise, and the roller 2 on the right rotates clockwise, that is, when the two rollers 2 rotate, they have the effect of lifting the tapered roller upward, thereby facilitating the roller to slide down along the rollers 2. The rollers 2 can be made of plastic with a smooth surface.

[0019] If too many tapered rollers fall into the top of the two rollers 2 at one time, the rollers that are first stuck in the gap between the two rollers 2 will form a support, and the other rollers will no longer be stuck in the gap between the two rollers 2, and will also slide down along the rollers 2. In order to prevent these rollers that are not stuck in the gap between the two rollers 2 from falling into the material guide tube 4, this embodiment is provided with a fan wheel 6 above the roller 2. When the fan wheel 6 rotates, it can prevent the rollers that are not stuck in the gap between the two rollers 2 from sliding down, and push these rollers back upwards, and the pushed back rollers can fall into the gap between the two rollers 2 again.

[0020] The roller diameters of different bearings are different. In order to adapt to the arrangement of rollers of different specifications, the distance between the two rollers 2 needs to be adjustable. In this embodiment, the two rollers 2 are installed on a movable mounting plate, and the mounting plates 7 at both ends of each roller 2 are hinged to the frame 1, and then the frame 1 is provided with a support column 8 on the outer side of the mounting plate 7, and a tension spring 9 is provided between the support column 8 and the mounting plate 7. The support column 8 is threadedly connected with an adjustment bolt 10 whose front end abuts against the mounting plate 7. When the adjustment bolt 10 is turned, the distance between the two rollers 2 can be adjusted, that is, the gap size between the two rollers 2 can be adjusted.

[0021] In order to tilt the two rollers 2, the bottom end of the frame 1 on which the rollers 2 are mounted is hinged to a base 11, and the base 11 is provided with a wedge 12 for adjusting the tilt angle of the frame 1; the wedge 12 is provided with a screw rod, which passes through a hole on a vertical plate on the base 11, and the screw rod is threadedly connected to nuts at both ends of the hole. By rotating the nuts, the position of the wedge 12 can be adjusted, thereby adjusting the tilt angle of the frame 1.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, and for the convenience of describing the technical solution, the front, rear, left, right, top, middle, and bottom directions adopted are based on the settings in the accompanying drawings, rather than limiting the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
