[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] In the description of this invention, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, in the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] This invention provides, for example Figures 1-14The above-displayed hanging device for bolt powder coating includes a support frame 1, a movable frame 2 installed on one side of the upper end of the support frame 1, multiple hanging nets 3 stacked longitudinally on the movable frame 2, a lifting frame 4 installed on one side of the upper end of the support frame 1, the lifting frame 4 can drive the multiple hanging nets 3 to move up and down, a feeding frame 5 is provided in the middle of the support frame 1, the feeding frame 5 is connected to the support frame 1 by multiple reinforcing ribs 6, a drive frame 7 is installed on one side of the feeding frame 5, an L-shaped feeding plate 8 is installed on the drive frame 7, the L-shaped feeding plate 8 has multiple bolt holding holes 9, an adjusting frame 10 is installed on the front side of the feeding frame 5, a feeding channel 11 is installed at the upper end of the adjusting frame 10, the feeding channel 11 can guide the bolts in the vibratory plate into the bolt holding holes 9.

[0034] The bolt hanging process of this device is as follows: Under normal conditions, the operator stacks multiple hanging nets 3 on the movable frame 2. The lifting frame 4 lifts all hanging nets except the bottom one upwards. The movable frame 2 moves the hanging nets 3, causing the first row of bolt holders on the hanging nets 3 to move to the side below the bolt holder holes 9. The operator adjusts the adjusting frame 10 according to the size of the bolts, causing the outlet end of the feeding channel 11 to tilt downwards and point towards the bolt holder holes 9. The bolt vibrating plate feeds the bolts into the feeding channel 11, and then the inclined plane causes the bolts to slide into the bolt holder holes 9. The drive frame 7 moves the L-shaped feeding plate 8. When the bolt holder hole 9 in the first position of the L-shaped feeding plate 8 moves away, the bolt holder hole 9 in the second position moves to the front of the feeding channel 11, allowing the second bolt to be fed. When all the bolt holder holes 9 on the L-shaped feeding plate 8 are filled with bolts, the bolt vibrating plate is turned off to stop feeding. Then, the drive frame 7 moves the L-shaped feeding plate 8 laterally. This allows the bolt to move above the mesh 3, and then the drive frame 7 moves the L-shaped feeding plate 8 downwards, allowing the bolt shank to pass through the mesh 3 and extend below it. The bolt end is intercepted and held on the mesh 3. Then, the moving frame 2 moves the mesh 3 forward one position, pushing the bolts off the L-shaped holding holes 9. At this point, the position of the second row of bolts on the mesh 3 moves below the L-shaped holding holes 9. The drive frame 7 then moves the L-shaped feeding plate 8 back to its original position. After the bolts are fed into the bolt holding hole 9 by the bolt vibratory feeder, the L-shaped feeding plate 8 and the bolts are moved by the drive frame 7, which facilitates the feeding of bolts. The above process is repeated several times until the hanging net 3 is full of bolts. Then, the hanging net 3 is moved away by the workers or mechanical equipment. The lifting frame 4 puts the hanging net 3 that was originally in the second row onto the moving frame 2. Then, the lifting frame 4 lifts the remaining hanging net 3. The moving frame 2 drives the hanging net 3 to move, which facilitates the continuous feeding of bolts.

[0035] Refer to the instruction manual appendix Figure 12The hanging net 3 includes a square frame 12, with a holding net 13 welded to the upper end of the square frame 12. Lifting holes 14 are opened at both ends of the front and rear sides of the square frame 12. The square frame 12 can easily support the holding net 13. The lifting holes 14 can facilitate the lifting frame 4 to lift and lower the square frame 12. The holding net 13 can facilitate the bolt shank to extend under the holding net 13 and intercept the end of the bolt.

[0036] Refer to the instruction manual appendix Figure 12 The holes 15 on the mesh 13 are diamond-shaped holes. The diamond-shaped holes 15 are combined with each other, which can save space to a great extent and reduce the contact area with the bolts.

[0037] Refer to the instruction manual appendix Figure 12 The square frame 12 has multiple connecting holes 16 on both sides of the upper end, and multiple connecting rods 17 are installed on both sides of the lower end. The connecting rods 17 on the upper hanging net 3 can be inserted into the connecting holes 16 on the lower hanging net 3. When the hanging nets 3 are stacked, the connecting rods 17 on the upper hanging net 3 can be inserted into the connecting holes 16 on the lower hanging net 3, thereby keeping the multiple hanging nets 3 as a whole and preventing the hanging nets 3 from shaking.

[0038] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Instruction manual attached Figure 6 Instruction manual attached Figure 9 Included with instruction manual Figure 14 The movable frame 2 includes a first servo motor 18 mounted on the support frame 1. A first ball screw 19 is mounted on the rotating end of the first servo motor 18. A first screw bearing 20 is mounted on one end of the first ball screw 19. The first screw bearing 20 is mounted on the support frame 1. A first screw sleeve 21 is threadedly connected to the first ball screw 19. A square holding rack 22 is mounted on the upper end of the first screw sleeve 21. First guide slides 23 are mounted on both sides of the lower end of the square holding rack 22. First guide blocks 24 are mounted on both sides of the upper end of the support frame 1. One end of the first guide block 24 extends into the first guide slide 23. Multiple limiting holes 25 are opened on both sides of the upper end of the square holding rack 22. The lower end of the connecting rod 17 on the bottom hanging net 3 is inserted into the limiting hole 25.

[0039] The process of the moving frame 2 moving the hanging net 3 is as follows: When the lifting frame 4 lowers the hanging net 3, the lower end of the connecting rod 17 at the lower end of the hanging net 3 can extend into the limiting hole 25, which facilitates the positioning of the hanging net 3. Then, the lifting frame 4 moves the remaining hanging net 3 upward, and starts the first servo motor 18 to rotate. The first servo motor 18 can drive the first ball screw 19 to rotate. Through the threaded connection between the first ball screw 19 and the first screw sleeve 21, the first screw sleeve 21 and the square holding rack 22 can be moved. The first guide block 24 and the first guide slide 23 can ensure the moving direction of the square holding rack 22, which can drive the hanging net 3 to move. When the hanging net 3 moves to below the bolt holding hole 9, it can hold the bolts. When the hanging net 3 is full of bolts, the hanging net 3 can be removed by the staff or mechanical equipment. Then the first servo motor 18 is started to reverse, which can drive the first ball screw 19 to reverse, which can drive the square holding rack 22 back to its original position. Then the second hanging net 3 is placed on the square holding rack 22 through the lifting frame 4.

[0040] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 3 Instruction manual attached Figure 6 Instruction manual attached Figure 9 Instruction manual attached Figure 11 Included with instruction manual Figure 13 The lifting frame 4 includes a fixed frame 26 mounted on one side of the upper end of the support frame 1. A second servo motor 27 is mounted inside the fixed frame 26. A second ball screw 28 is mounted on the rotating end of the second servo motor 27. A second screw bearing 29 is mounted on the upper end of the second ball screw 28. The upper end of the second screw bearing 29 is mounted on the fixed frame 26. A second screw sleeve 30 is threadedly connected to the second ball screw 28. A first lifting plate 31 is mounted on the front side of the second screw sleeve 30. Second guide rails 32 are mounted on both sides of the rear surface of the first lifting plate 31. The fixed frame 2... The first lifting plate 31 has a number of guide rods 34 installed at both ends. Two lifting plates 35 are provided on the front side of the first lifting plate 31. Multiple guide cylinders 36 are installed on one end of the lifting plate 35. The guide cylinders 36 are fitted on the outside of the guide rods 34. Multiple lifting rods 37 are installed on the lower inner side of the lifting plate 35. One end of the lifting rods 37 can extend into the lifting hole 14. A telescopic cylinder 38 is installed on one end of the first lifting plate 31. The telescopic end of the telescopic cylinder 38 is connected to one side surface of the lifting plate 35.

[0041] The process of lifting and lowering the hanging net 3 by the lifting frame 4 is as follows: Under normal conditions, all the hanging nets 3 are placed on the moving frame 2. The second servo motor 27 is started to rotate, which drives the second ball screw 28 to rotate. The second ball screw 28 and the second screw sleeve 30 are connected by bolts, which allows the second screw sleeve 30 and the first lifting plate 31 to move downward. The second guide block 33 and the second guide slide 32 can ensure the moving direction of the first lifting plate 31. When the first lifting plate 13 moves downward, it can be driven by the guide rod 34 and the guide cylinder 36. The lifting plate 35 moves downward, causing the lifting rod 37 to move to the side of the lifting hole 14 on the second layer of the hanging net 3 from the bottom. Then, the telescopic cylinder 38 is activated to shorten, which can drive the lifting plate 35 and the lifting rod 37 to move closer to the hanging net 3. The guide rod 34 and the guide cylinder 36 can ensure the direction of movement of the lifting plate 35 and the lifting rod 37. At this time, the lifting rod 37 can move into the lifting hole 14. Then, the second servo motor 27 is activated to reverse. The second servo motor 12 can drive the second ball screw 28 to reverse, which can then cause the second screw sleeve 30 and the first lifting plate to move in opposite directions. 31. The lifting plate 35 and lifting rod 37 move upward, lifting the bottommost hanging net 3, and allowing the connecting rod 17 on the second layer of hanging net 3 from the bottom to be removed from the connecting hole 16 on the bottommost hanging net 3. This allows the moving frame 2 to move the bottommost hanging net 3. After the hanging net 3 is full of bolts and removed, the moving frame 2 returns to its original position. Then, the second servo motor 27 rotates, driving the second ball screw 28 to rotate, causing the second screw sleeve 30, the first lifting plate 31, the lifting plate 35, and the lifting rod 37 to move downward, and placing the hanging net 3 down. Placed on the movable frame 2, the telescopic cylinder 38 is extended to push the lifting plate 35 and the lifting rod 37, causing the lifting rod 37 to move to the outside of the lifting hole 14. Then, the second servo motor 27 is reversed and drives the second ball screw 28 to rotate, causing the second screw sleeve 30, the first lifting plate 31, the lifting plate 35, and the lifting rod 37 to move upward, allowing the push rod 37 to move to the lifting hole 14 of the next layer. The telescopic cylinder 38 is then shortened to pull the lifting rod 37 into the lifting hole 14, making it easier to push the remaining hanging net 3 upward.

[0042] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 4 Instruction manual attached Figure 6 Instruction manual attached Figure 7 Instruction manual attached Figure 9 Included with instruction manual Figure 10The loading rack 5 is a U-shaped frame 39, which is connected to the support frame 1 by reinforcing ribs 6.

A fourth guide block 49 is installed on the upper and lower ends of the front surface of the second lifting plate 41. One end of the fourth guide block 49 extends into the fourth guide slide 48.

[0043] The process of the drive frame 7 moving the L-shaped feeding plate 8 is as follows: Under normal conditions, the L-shaped feeding plate 8 is located on one side of the feeding channel 11. When feeding bolts, the third servo motor 44 is started to rotate. The third servo motor 44 can drive the third ball screw 45 to rotate. Through the threaded connection between the third ball screw 45 and the third screw sleeve 47, the third screw sleeve 47 and the L-shaped feeding plate 8 can be moved. The fourth guide block 49 and the fourth guide slide 48 can ensure the moving direction of the L-shaped feeding plate 8. After the bolts are placed in the bolt holding hole 9, the L-shaped feeding plate 8 moves above the hanging mesh 3. Then, the lifting cylinder 40 is activated to extend, which can drive the second lifting plate 41 to move downward. Block 43 and the third guide slide 42 can ensure the moving direction of the second lifting plate 41. When the second lifting plate 41 moves downward, the L-shaped feeding plate 8 can be moved downward through the fourth guide block 49 and the fourth guide slide 48, so that the lower end of the bolt can be extended into the hanging net 3. Then, when the moving frame 2 drives the hanging net 3 to move, the bolt can be pushed out from the bolt holding hole 9. Then, the lifting cylinder 40 is activated to shorten, which can drive the second lifting plate 41 and the L-shaped feeding plate 8 to move upward. Then, the third servo motor 44 is activated to reverse and drive the third ball screw 45 to rotate. Through the threaded connection between the third ball screw 45 and the third screw sleeve 47, the L-shaped feeding plate 8 can be driven back to its original position.
