DETAILED DESCRIPTION

[0021] The present invention will be further described below with reference to the embodiments.

[0022] See also Figure 1-4 The utility model provides a nail feeding mechanism for a drum-type nail feeding machine, including a workbench 1, a feed hopper 2, a conveying mechanism 3, a rotating drum 4 and a nail feeding mechanism 5. The feed hopper 2 is fixedly connected to the upper right side of the workbench 1, the conveying mechanism 3 is arranged on the left side of the feed hopper 2, the rotating drum 4 is arranged on the left outside of the conveying mechanism 3, and the rotating drum 4 is fixedly connected to the top of the workbench 1, and the nail feeding mechanism 5 is arranged on the front side of the rotating drum 4.

[0023] The nail feeding mechanism 5 consists of a support rod 501, a limiting rod 502, a guide plate 504, a transmission plate 505 and a conveyor belt 506. The support rod 501 is symmetrically fixedly connected to the inside of the rotating cylinder 4, and the limiting rod 502 is fixedly connected to the front side of the top end of the support rod 501. A delivery port 503 is opened on the front side of the rotating cylinder 4, and the limiting rod 502 passes through the inside of the delivery port 503.

[0024] Further as Figure 1 、 Figure 2 and Figure 4 As shown, it is worth noting that the guide plate 504 is fixedly connected to the front of the conveying port 503 , and the top surface of the guide plate 504 is provided with an inclined surface, and the conveying plate 505 is fixedly connected to the front side of the guide plate 504 .

[0025] Further as Figure 1 、 Figure 2 and Figure 4As shown, it is worth noting that the spacing between the limiting rods 502 is larger than the size of the stud in the screw and smaller than the size of the head in the screw;

[0026] When the screw turns over inside the rotating cylinder 4, the screw head will be caught by the limiting rod 502. The inclined limiting rod 502 can deliver the screw to the outside of the rotating cylinder 4 through the delivery port 503, facilitating the subsequent delivery of the screw.

[0027] Further as Figure 1 、 Figure 2 and Figure 4 As shown, it is worth noting that a nail feeding groove is provided on the top surface of the conveying plate 505, a conveyor belt 506 is provided inside the nail feeding groove, and a micro motor is provided at the front end of the conveyor belt 506 to control the operation of the conveyor belt 506;

[0028] The head of the screw is guided by the inclined surface of the guide plate 504 to the top of the conveyor belt 506 inside the conveyor plate 505. The operation of the conveyor belt 506 can convey the screw forward along the nail feeding groove and finally to the cavity of the stud welding gun to ensure the normal use of the welding gun.

[0029] According to the above working process, it can be seen that: through the provided nail feeding mechanism 5, the screws can be placed inside and above the two limit rods 502 in a unified direction, and transported to the top of the conveyor belt 506 through the conveying port 503 and the guide plate 504, so that the screw heads are uniformly oriented in the conveying direction, which facilitates the subsequent screws to be transported to the inside of the gun head of the stud welding gun for use, and the nail feeding is stable and practical.

[0030] Further as Figure 1 、 Figure 2 and Figure 3 As shown, it is worth mentioning that the conveying mechanism 3 is composed of a connecting cylinder 301, a motor 302, a transmission shaft 303, a spiral conveying blade 304, a connecting block 305, a rotating rod 306 and a rotating plate 307. The connecting cylinder 301 is fixedly connected to the left side of the feed hopper 2, the motor 302 is fixedly connected to the middle of the right side of the feed hopper 2, the transmission shaft 303 is fixedly connected to the output end of the motor 302, and the transmission shaft 303 is rotatably connected to the rotating cylinder 4, the spiral conveying blade 304 is fixedly connected to the right side outside of the transmission shaft 303, and the spiral conveying blade 304 is arranged inside the feed hopper 2 and the connecting cylinder 301.

[0031] Further as Figure 1 、 Figure 2 and Figure 3 As shown, it is worth noting that the connecting block 305 is symmetrically fixedly connected to the left outer portion of the transmission shaft 303, the rotating rod 306 is symmetrically fixedly connected to the outer portion of the connecting block 305, and the rotating plate 307 is fixedly connected to one end of the rotating rod 306, and the rotating plate 307 is close to the inner wall of the rotating cylinder 4;

[0032] The connecting block 305 , the rotating rod 306 and the rotating plate 307 rotate along with the transmission shaft 303 , playing the role of stirring and assisting transmission, ensuring that the screw is turned over inside the rotating cylinder 4 so that it can be transmitted evenly and smoothly.

[0033] This solution has the following working process: when in use, first pour the screws into the inside of the feed hopper 2, start the motor 302 to drive the transmission shaft 303 to rotate, thereby driving the spiral conveying blade 304 to rotate, and conveying the screws inside the feed hopper 2 to the inside of the rotating cylinder 4. At the same time, the connecting block 305 drives the rotating rod 306 and the rotating plate 307 to rotate, so that the thread inside the rotating cylinder 4 is flipped and rotated. During the rotation process, the screws fall above the two limit rods 502, and the limit rods 502 limit the arrangement of the screws. The limit rods 502 are set to an angle, and the screws arranged above are output to the outside of the rotating cylinder 4 through the conveying port 503 through the inclined limit rods 502. The screws are tilted by the inclined surface set by the guide plate 504, and the micro motor is controlled to start the conveyor belt 506 at the same time. The tilted screws contact the surface of the conveyor belt 506. The friction between the screws and the conveyor belt 506 can drive the screws to be conveyed to the inside of the gun head of the stud welding gun, and the conveying direction of the screws is unified to ensure the normal use of the stud welding gun.

[0034] In summary: through the provided nail feeding mechanism 5, the screws can be placed inside and above the two limit rods 502 in a unified direction, and transported to the top of the conveyor belt 506 through the conveying port 503 and the guide plate 504, so that the screw heads are uniformly oriented in the conveying direction, which facilitates the subsequent delivery of the screws to the gun head of the stud welding gun for use, and the nail feeding is stable and practical; through the provided conveying mechanism 3, the screws poured into the feed hopper 2 can be transported to the inside of the rotating cylinder 4, which can ensure that the screws are delivered to the top of the nail feeding mechanism 5, thereby facilitating the subsequent nail feeding operation of the screws, and further improving the practicality and full automation of the mechanism.
