In addition, in the description of the present invention, the meaning of "a plurality of" is two or more unless otherwise specifically defined.

[0018] The present invention provides a fully automatic feeding device for nut spraying as shown in Figure 1-17 Figure 5, which includes a support frame 1. The support frame 1 is installed on the ground through anchor bolts 2. On one side of the upper end of the support frame 1, a workbench 3 is installed. On the other side of the upper end of the support frame 1, a fixing frame 4 is installed. A feeding mechanism and a hanging mechanism are installed on the workbench 3. The feeding mechanism includes a feeding channel 5 installed on the workbench 3. A moving frame 6 is installed on the workbench 3. A placing table 7 is installed on the moving frame 6. A plurality of placing grooves 8 are formed on the placing table 7. The hanging mechanism includes a lifting frame 9 installed on the fixing frame 4. A hanging net 10 is placed on the lifting frame 9. A plurality of hooks 11 are installed on the hanging net 10. A pushing frame 12 is installed on the moving frame 6. The pushing frame 12 can push the nuts in the placing groove 8 onto the hooks 11.

[0019] The process of hanging the nuts by this device is as follows: A large number of nuts are placed in the vibrating bowl. Through the vibration of the vibrating bowl, the nuts can be moved into the feeding channel 5. The feeding channel 5 can guide the nuts into the first placing groove 8 on the placing table 7. By driving the placing table 7 to move through the moving frame 6, a plurality of placing grooves 8 can pass through the outlet end of the feeding channel 5 in sequence, so that all the placing grooves 8 are filled with nuts. The hanging net 10 is placed on the lifting frame 9 in advance. The lifting frame 9 can drive the hanging net 10 to move up and down. By moving the uppermost row of hooks 11 on the hanging net 10 in front of the placing groove 8 through the lifting frame 9, and driving the placing table 7 to move through the moving frame 6, the placing table 7 is moved in the direction close to the hooks 11, and then the nuts are pushed onto the hooks 11 and hung by the pushing frame 12. By driving the placing table 7 to return to its original position through the moving frame 6, then the placing table 7 is moved again, and nuts are continuously placed in the placing groove 8. By driving the hanging net 10 to move upward through the lifting frame 9, and moving the second layer of hooks 11 in front of the placing groove 8, and driving the placing table 7 to move through the moving frame 6, the placing table 7 is moved in the direction close to the hooks 11, and then the nuts are pushed onto the hooks 11 and hung by the pushing frame 12. And so on, nuts can be hung on all the hooks 11 on the hanging net 10. When the nuts are fully hung, a new hanging net 10 is replaced, and the feeding can be carried out again.

[0020] Refer to the attached drawings of the specification Figure 1 and the attached drawings of the specification Figure 5 and the attached drawings of the specification Figure 8 There are two feeding channels 5. The lower end of one feeding channel 5 is installed on the workbench 3 through the first connecting frame 13, and the other feeding channel 5 is installed on the fixing frame 4 through the second connecting frame 14. The upper ends of the two feeding channels 5 are connected by a connecting rod 15, and the lower ends of the two feeding channels 5 are connected by a fixing plate 16, which can double the feeding efficiency and reduce the moving distance of the moving table 7.

[0021] Refer to the attached drawings of the specification Figure 8 The number of the containing grooves 8 on the containing table 7 is even. When the containing table 7 is in the starting position, the outlet end of the first feeding channel 5 is located at the first containing groove 8 on the containing table 7, and the outlet end of the second feeding channel 5 is located at the containing groove 8 at the rear of the middle position of the containing table 7, which can make the feeding quantities of the two feeding channels 5 on the containing table 7 the same. The shape of the containing groove 8 is U-shaped, and the depth of the containing groove 8 is lower than the outer diameter of the nut, which can make the upper end of the nut located above the upper surface of the containing table 7, so that when the containing table 7 moves, it will not collide with the nut in the feeding channel 5.

[0022] Refer to the attached drawings of the specification Figure 1 and the attached drawings of the specification Figure 3 and the attached drawings of the specification Figure 5 and the attached drawings of the specification Figure 6 and the attached drawings of the specification Figure 10 and the attached drawings of the specification Figure 16 and the attached drawings of the specification Figure 17 Guide rods 17 are installed on both sides of the fixing plate 16, guide cylinders 18 are installed on the outer sides of the guide rods 17, a moving plate 19 is provided on one side of the fixing plate 16, the moving plate 19 is installed on the guide cylinder 18, a first telescopic cylinder 20 is installed on the moving plate 19, a circular hole 21 is formed on the moving plate 19, the telescopic end of the first telescopic cylinder 20 passes through the circular hole 21 and is connected with the fixing plate 16, intercepting plates 22 are installed on both sides of the lower end of the moving plate 19, intercepting holes 23 are formed on the intercepting plates 22, and the intercepting plates 22 can move to the lower part of the outlet end of the feeding channel 5.

[0023] The process of the intercepting plate 22 intercepting nuts is as follows: Under normal conditions, the intercepting plate 22 is located on one side of the outlet end of the feeding channel 5 and will not obstruct the discharging of the feeding channel 5. After all the containing grooves 8 on the containing table 7 are filled with nuts, the first telescopic cylinder 20 is activated to shorten, which can drive the moving plate 19 to move towards the fixed plate 16. The guiding cylinder 18 and the guiding rod 17 can ensure the moving direction of the moving plate 19. When the moving plate 19 moves, the intercepting plate 22 can be moved below the outlet end of the feeding channel 5, and the intercepting holes 23 can avoid the nuts, thereby intercepting the nuts in the feeding channel 5. When the moving frame 6 drives the containing table 7 to move towards the hook 11, it can prevent the nuts in the feeding channel 5 from falling. When the moving frame 6 drives the containing table 7 back to its original position, the first telescopic cylinder 20 is activated to extend, which can make the moving plate 19 move away from the fixed plate 16 and drive the intercepting plate 22 back to its original position. At this time, the intercepting plate 22 no longer intercepts the nuts, which is convenient for nut feeding.

[0024] Refer to the attached drawings of the specification Figure 1 , the attached drawings of the specification Figure 3 , the attached drawings of the specification Figure 4 , the attached drawings of the specification Figure 5 , the attached drawings of the specification Figure 6 , the attached drawings of the specification Figure 7 , the attached drawings of the specification Figure 8 , the attached drawings of the specification Figure 9 and the attached drawings of the specification Figure 10 , the moving frame 6 includes a moving table 24 located above the workbench 3.

The guiding table 35 and the guiding channel 34 can ensure the moving direction of the supporting table 33. When the supporting table 33 moves, the placing table 7 can be driven to move, so that multiple placing grooves 8 can pass below the feeding channel 5. When there are nuts in all the placing grooves 8, start the second telescopic cylinder 27 to extend. The second telescopic cylinder 27 can drive the moving table 24 to move in the direction close to the hook 11. The guiding block 26 and the guiding slideway 25 can ensure the moving direction of the moving table 24. When the moving table 24 moves, the intercepting table 32, the supporting table 33, and the placing table 7 can be driven to move. Then, the nuts are loaded through the pushing frame 12. After the loading is completed, start the second telescopic cylinder 27 to shorten and start the first servo motor 28 to rotate in reverse, so that the intercepting table 32, the supporting table 33, and the placing table 7 can return to their original positions. The placing table 7 is installed on the square groove 36 by bolt connection, which is convenient to replace different placing tables 7 according to different sizes of nuts, thereby increasing the applicability of this device.
