The conveyor belt 200 is horizontally installed at the discharge port on the whole-aligning machine body 100 to enable the whole-aligning machine body 100 to align the welding studs, so that the aligned welding studs enter the conveyor belt 200. The sorting mechanism 300 is installed on the conveyor belt 200 and is used for stacking and arranging the welding studs in the right direction. The adjusting mechanism 400 is installed at the bottom of the discharge port end of the conveyor belt 200 and is used for adjusting the feeding direction of the welding studs. The pushing mechanism 500 is in contact with the discharge port of the adjusting mechanism 400 and is used for feeding the welding studs. The sorting mechanism 300 includes a fixing plate 310, a sorting plate 320 and a material-limiting plate 330. The fixing plate 310 is vertically installed on the side of the conveyor belt 200. The sorting plate 320 is movably installed on the fixing plate 310 through a connecting rod. The sorting plate 320 is in a triangular structure. A limiting rod 340 is also arranged on the fixing plate 310. The limiting rod 340 is arranged at the front end of the connecting rod and is used for limiting the rotation direction of the sorting plate 320, so that the sorting plate 320 rotates counterclockwise, enabling the welding studs to move through the sorting plate 320 from the shank to the head direction, while the welding studs cannot pass through the sorting plate 320 from the head to the shank direction and directly enter the inside of the whole-aligning machine body 100 along the inclined surface of the sorting plate 320. At the same time, a first connecting ear plate is arranged at the front end of the connecting rod, and a corresponding second connecting ear plate is arranged at the front end of the limiting rod 340 on the fixing plate 310. A restoring member 350 is arranged between the first connecting ear plate and the second connecting ear plate. The restoring member 350 is used for the rotational restoration of the sorting plate 320. The material-limiting plate 330 is installed in the adjusting groove 311 on the fixing plate 310 through a fixing bolt, so that the material-limiting plate 330 limits the overlapping welding studs on the conveyor belt 200 to make the welding studs arranged individually.

The two adjusting plates 410 are respectively installed on both sides of the discharge port of the conveyor belt 200, and the two sliding strips 420 are respectively installed on the inner sides of the two adjusting plates 410, so that an adjusting and transmission channel is formed between the two adjusting plates 410 for adjusting the welding studs falling from the conveyor belt 200 from the horizontal direction to the vertical direction.

[0027] During the automatic feeding of studs by the fully automatic stud welding nail automatic feeder, the studs after cleaning enter the material tank on the aligning machine body 100, and after alignment by the aligning machine body 100, they are conveyed into the conveyor belt 200. The sorting mechanism 300 provided on the conveyor belt 200 limits and sorts the studs conveyed on the conveyor belt 200, so that the studs move individually along the set direction along the conveyor belt 200. The studs with inconsistent nesting and arrangement directions are sorted into the aligning machine body 100 for re-alignment. The sorted studs fall from the discharge port of the conveyor belt 200 into the inclined adjustment plate 410, so that the studs are adjusted from the horizontal direction to the vertical direction for conveyance, and the studs move along the inclined slide bar 420 provided inside the adjustment plate 410 to the pushing mechanism 500, so that the pushing mechanism 500 pushes the studs into the next processing step for processing, thus replacing the original manual sorting of the conveying direction of studs, improving the automatic feeding efficiency and feeding quality of the fully automatic stud welding nails.

[0028] As a preferred embodiment, please refer to Figure 1 and Figure 2 , the sorting plate 320 is of a triangular structure, and the triangular structure of the sorting plate 320 decreases from large to small along the conveying direction of the conveyor belt 200.

After the sorting plate 320 rotates along the connection between the connecting plate and the fixing plate 310, the metal spring of the restoring member 350 stretches. After the sorting is completed, the metal spring of the restoring member 350 contracts, thereby driving the sorting plate 320 to return.

[0030] As a preferred embodiment, please refer to Figure 1 and Figure 4 , the limiting plate 330 can move vertically along the adjustment groove 311 to adjust its limiting height, so that the limiting plate 330 is used to limit studs of different diameters.

[0031] As a preferred embodiment, please refer to Figure 1 and Figure 2 , the front end of the adjustment plate 410 is inclined, facilitating the vertically arranged studs to move along the inclined slide bar 420 to the front end of the adjustment plate 410 by inertia.

[0032] As a preferred embodiment, please refer to Figure 1 and Figure 2, the pusher mechanism 500 includes a pusher cylinder 510 and a pusher plate 520. The rear end of the pusher plate 520 is fixedly connected to the output end of the pusher cylinder 510. The pusher plate 520 has a rectangular structure, and a card slot is provided on the contact surface between the pusher plate 520 and the adjustment plate 410. The card slot is used for the snap connection of the welding nails, so that the pusher cylinder 510 can push the welding nails snapped by the pusher plate 520 to move horizontally, completing the automatic feeding of the welding nails.

[0033] As a preferred embodiment, please refer to Figure 3 , the aligning machine body 100 includes a material box 110, a plurality of fixed aligning plates 120, a plurality of conveying plates 130, a connecting rod 140, a crankshaft 150, and a rotation driving member 160.

The plurality of conveying plates 130 are installed in the middle of each fixed aligning plate 120. The bottoms of the plurality of conveying plates 130 are connected to the connecting rod 140 through a connecting plate. The other end of the connecting rod 140 is installed on the crankshaft 150. The crankshaft 150 is connected to the output end of the rotation driving member 160 through a belt, so that the rotation driving member 160 drives the crankshaft 150 to rotate, thereby driving the connecting rod 140 on the crankshaft 150 to move reciprocally, so that the plurality of conveying plates 130 installed on the connecting plate of the connecting rod 140 move reciprocally, so that the reciprocating movement of the plurality of conveying plates 130 can sort the welding nails in the material box 110 and convey them onto the conveyor belt 200.

[0034] The working principle of the present utility model is:

[0035] During the automatic feeding of studs by the full-automatic stud welding nail automatic feeder, the cleaned studs enter the material trough on the body 100 of the aligning machine. The rotating driving member 160 on the body 100 of the aligning machine drives the crankshaft 150 to rotate, thereby driving the connecting rod 140 on the crankshaft 150 to reciprocate, so that a plurality of conveying plates 130 installed on the connecting plate of the connecting rod 140 reciprocate between a plurality of fixed aligning plates 120, so that the reciprocating movement of the plurality of conveying plates 130 sorts the studs in the material box 110 and conveys the aligned studs into the conveyor belt 200. A sorting mechanism 300 is provided on the conveyor belt 200. A height-adjustable limiting plate 330 is provided in the adjustment groove 311 of the sorting mechanism 300 to limit the studs conveyed on the conveyor belt 200, so that the studs are conveyed individually on the conveyor belt 200. At the same time, a sorting plate 320 with a triangular structure is also provided on the fixing plate 310 of the sorting structure. The sorting plate 320 rotates unidirectionally along the connection between the connecting rod and the fixing plate 310, and the triangular sorting plate 320 sorts the studs with inconsistent arrangement directions, so that the studs with inconsistent arrangement directions enter the body 100 of the aligning machine for re-aligning. When the sorting is completed, the sorting plate 320 returns under the contraction of the return member 350, the metal spring, thereby improving the sorting efficiency of the sorting mechanism 300 for the studs. The sorted studs fall from the discharge port of the conveyor belt 200 into the inclined adjustment plate 410, so that the studs are adjusted from the horizontal direction to the vertical direction for conveying, so that the studs move along the inclined sliding strips 420 provided inside the adjustment plate 410 to the pushing mechanism 500. The pushing cylinder 510 on the pushing mechanism 500 pushes the pushing plate 520 with the studs clamped thereon under the input of high-pressure gas to push the studs into the next processing step for processing, thereby replacing the original manual sorting of the conveying direction of the studs, and improving the automatic feeding efficiency and feeding quality of the full-automatic stud welding nails.

[0036] The beneficial effects of the present utility model are as follows:

[0037] First, by providing a sorting mechanism 300 on the conveyor belt 200 of the full-automatic stud welding nail automatic feeder, the limiting plate 330 on the sorting mechanism 300 limits the studs that are overlapped and conveyed on the conveyor belt 200, so that the studs are conveyed individually. At the same time, the triangular sorting plate 320 on the sorting mechanism 300 sorts the studs with inconsistent arrangement directions, so that the unqualified studs after sorting enter the inside of the body 100 of the aligning machine for re-aligning and conveying, improving the automatic feeding efficiency and feeding quality of the full-automatic stud welding nails;

[0038] Second, by arranging an adjustment mechanism 400 between the conveyor belt 200 and the pusher mechanism 500 on the automatic stud welding nail automatic feeder, the two adjustment plates 410 on the adjustment mechanism 400 are installed in an inclined shape at the bottom of the discharge port of the conveyor belt 200, so that the welding nails horizontally conveyed on the conveyor belt 200 fall from the discharge port into the middle of the two adjustment plates 410, are adjusted from a horizontal state to a vertical state, and slide along the inclined slide bar 420 to the discharge port, thereby improving the automatic feeding efficiency and feeding quality of the automatic stud welding nails.

At the same time, the scope of the utility model involved in the present application is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept of the utility model.
