[0034] See also Figures 1 to 4 The embodiment of the present application discloses a nut directional feeding device, including a material frame 1, a lifting mechanism 2, a translation mechanism and a screening mechanism; the material frame 1 is provided with a receiving groove 11 for accommodating nuts, and the material frame 1 is provided with a feeding port 12 and a discharge port 13 connected to the receiving groove 11; the lifting mechanism 2 includes a lifting block 21 and a lifting drive 22, and the lifting drive 22 is fixedly installed in the material frame 1, and the output end of the lifting drive 22 is connected to the lifting block 21, and the lifting block 21 is located in the receiving groove 11 and moves toward the discharge port 13 to discharge the nuts in the receiving groove 11 from the discharge port 13; the translation mechanism is provided at the discharge port 13 of the material frame 1, and the translation mechanism is used to translate the nuts to an external device; the screening mechanism is connected to the translation mechanism, and the screening mechanism is used to screen out nuts arranged vertically on the translation mechanism.

[0035] As can be seen from the above, by setting a accommodating groove 11 in the material frame 1, multiple nuts are accommodated in the accommodating groove 11, and through the lifting mechanism 2, the lifting driver 22 drives the lifting block 21 to move, and the lifting block 21 drives the nuts to be discharged from the discharge port 13, and then the nuts are translated to the external equipment through the translation mechanism. At the same time, by setting a screening mechanism, the nuts arranged vertically on the translation mechanism are screened out, and the directional nut loading process is fully automated, replacing manual operation, thereby improving loading efficiency and quality.

[0036] In this embodiment, a plurality of steps 14 are fixedly provided in the accommodating groove 11, and the plurality of steps 14 extend progressively from bottom to top to the discharge port 13. Each of the steps 14 is provided with a ejecting block 21, and the plurality of ejecting blocks 21 are connected to the output end of the ejecting driver 22, thereby avoiding pusher blockage and facilitating the ejection of the ejecting block 21.

[0037] In this embodiment, the upper end surfaces of the step 14 and the ejection block 21 are inclined, and the ejection block 21 is arranged at the inclined lower end of each step 14, thereby preventing the nut from falling off the ejection block 21 and improving the reliability of ejection.

[0038] In this embodiment, the ejection mechanism 2 also includes a guide rod 23 and a slider 24. The guide rod 23 is fixedly installed in the material frame 1, and the slider 24 is slidably set on the guide rod 23 and fixedly connected to the multiple ejection blocks 21, thereby enabling the ejection blocks 21 to move stably and improving the ejection reliability of the ejection mechanism 2.

[0039] In this embodiment, the ejecting driver 22 is a cylinder, which can realize the movement of the ejecting block 21.

[0040] In this embodiment, a guide plate 5 is provided at the discharge port 13 and is arranged toward the translation mechanism, thereby enabling the nut to accurately enter the translation mechanism from the discharge port 13, thereby improving the feeding stability.

[0041] In this embodiment, the translation mechanism includes a pulley conveying structure 3, and the pulley conveying structure 3 is provided with a tensioning pulley 32 for tensioning the conveying belt 31, thereby realizing translation feeding of nuts and facilitating subsequent detection processes of the nuts.

[0042] In this embodiment, the translation mechanism further includes a baffle 33 , which is extended toward the nut transport direction, thereby preventing the nuts from falling off the conveyor belt 31 and improving the reliability of feeding.

[0043] In this embodiment, the screening mechanism includes a stopper 4 positioned above the conveyor belt 31. A channel 6 is formed between the stopper 4 and the conveyor belt 31.

The slider 24 drives the ejecting block 21 to move, so that the ejecting block 21 drives the nuts to move toward the discharge port 13 and are discharged from the discharge port 13. The nuts pass through the guide plate 5 and enter the conveyor belt 31. The conveyor belt 31 conveys the nuts in a horizontal manner. At the same time, the block 4 screens out the nuts arranged vertically and continues to be transported to the external equipment by the conveyor belt 31 for feeding, while the other nuts are sent back to the material trough through the return channel 7, thereby realizing the nut screening, orientation and feeding. The whole process is automated, replacing manual operation, and improving the efficiency and quality of directional feeding.
