DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0017] Attached Figure 1As shown in FIGS. 1-6, a rivet puller type nail feeder includes a housing, a lifting device, a rivet queuing and sorting device, a moving device, and a control system; the lifting device includes a secondary elevator 9 and a hopper 8 around the elevator; the rivet queuing and sorting device includes a V-shaped queuing groove 10, a linear vibrator 4 is arranged below the V-shaped queuing groove 10, and the side is connected to the secondary elevator 9. The secondary elevator 9 lifts the rivet nuts into the V-shaped queuing groove 10. The V-shaped queuing groove 10 is connected to a rivet sorting and queuing groove 12. A material height detector 11 is arranged on the side of the rivet sorting and queuing groove 12. The rivet sorting and queuing groove 12 is connected to a nail cutting mechanism; the nail cutting mechanism includes a box body 6 and a nail cutting cylinder 7. The nail cutting cylinder 7 is fixed at one end of the box body 6. A sliding block 17 is arranged in the box body 6 and is connected to the push rod of the nail cutting cylinder 7. A sliding plate groove 20 is arranged on the sliding block 17. A circular pit 22 is arranged below the sliding plate groove 20. The circular pit 22 communicates with the rivet sorting and queuing groove 12. A sliding plate 18 is slidably arranged in the sliding plate groove 20. A U-shaped groove 19 is arranged on the sliding plate 18. In the initial state, the opening of the U-shaped groove 19 is aligned with the rivet sorting and queuing groove 12. A guide pin 14 is also fixed on the sliding plate 18. A guide plate 16 is fixed on the upper surface of the box body 6. An L-shaped sliding groove 13 is arranged on the guide plate 16. One groove of the L-shaped sliding groove 13 is parallel to the moving direction of the push rod of the nail cutting cylinder, and the other groove communicates with the rivet sorting and queuing groove 12. A guide groove 15 with an included angle with the moving direction of the push rod of the nail cutting cylinder is also arranged on the guide plate 16. The guide pin 14 is located in the guide groove 15. A blanking pipe 5 is arranged on the bottom surface of the box body; a feed inlet 2 and a control panel 3 are arranged on the housing 1,

[0018] The V-shaped queuing groove 10 and the rivet sorting and queuing groove 12 have slopes. The end of the V-shaped queuing groove 10 far from the rivet sorting and queuing groove 12 is higher, and a notch is arranged at the end close to the rivet sorting and queuing groove 12. Only one rivet nut can pass through the notch of the V-shaped queuing groove 10, and the excess automatically falls into the hopper 8.

[0019] The width of the rivet sorting and queuing groove 12 is larger than the lower end diameter of the rivet nut and smaller than the mushroom head diameter of the rivet nut.

[0020] When the push rod of the nail cutting cylinder 7 is pushed out to the limit position, the blanking pipe 5 on the bottom surface of the box body 6 is aligned with the circular pit on the sliding block 17.

[0021] During use, pour the rivet nuts into the hopper 8, start the linear vibrator 4 and the secondary elevator 9. The rivet nuts 21 are lifted into the V-shaped queuing trough 10 and move towards the rivet sorting and queuing trough 12 under the vibration of the linear vibrator 4. When passing through the notch on the rivet sorting and queuing trough 12, the excess rivet nuts fall into the hopper 8, and only one rivet nut enters the rivet sorting and queuing trough 12. Since the width of the rivet sorting and queuing trough 12 is smaller than the diameter of the mushroom head of the rivet nut, the mushroom heads of the rivet nuts are arranged in sequence in the rivet sorting and queuing trough 12 and enter the U-shaped groove 19 provided on the sliding plate 18 in the box body 6. The control system starts the nail-cutting cylinder 7 to push the rivet nut 21 forward. At the same time, the guide pin 14 moves outward along the guide groove 15, driving the sliding plate 18 and the rivet nut 21 to move outward. Finally, the rivet nut 21 detaches from the sliding plate 18, falls into the blanking pipe 5, and is blown away by high-pressure air.

[0022] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
