[0026] Please refer to Figures 1-10 , an embodiment provided by the present utility model: a feeding device for large-sized materials, including a lifting frame 1 and a belt conveyor 2. The outside of the lifting frame 1 is provided with a belt conveyor 2. At the top of the belt conveyor 2 on one side of the lifting frame 1, an alignment frame 3 is installed. On the top of the belt conveyor 2 on one side of the alignment frame 3, two groups of first conveyor belts 31 are arranged. On the outside of the belt conveyor 2 away from the lifting frame 1, a fork arm elevator 4 is provided. The outside of the fork arm elevator 4 is provided with a forklift 5. On one side of the forklift 5, multiple groups of placement boards 6 are arranged. On the outside of the lifting frame 1 away from the belt conveyor 2, a multi-layer shelf 7 is provided. The outside of the multi-layer shelf 7 is provided with an AGV cart 8. Inside the lifting frame 1, a lifting conveyor 9 is provided. At the top of the lifting conveyor 9, a support frame 13 is installed. On the top of the lifting conveyor 9 on one side of the support frame 13, two groups of second conveyor belts 32 are arranged. At the bottom of the support frame 13 above the lifting conveyor 9, support plates 14 are symmetrically installed. At the bottom of each support plate 14, a first electric push rod 15 is installed. The first electric push rod 15 plays a role in power output. At the output end of each first electric push rod 15, a telescopic rod 16 is installed. On the bottom of the support plate 14 on one side of the telescopic rod 16, a sliding plate 17 is slidably installed, and the telescopic rods 16 are all connected to the sliding plate 17. At the bottom of each sliding plate 17, a push plate 18 is provided. At one end of the push plate 18 close to the sliding plate 17, a hinge shaft 19 is installed, and each push plate 18 is movably connected to the sliding plate 17 through the hinge shaft 19. On the inner wall of the lifting frame 1 on one side of the lifting conveyor 9, right-angle motors 10 are symmetrically installed;

[0027] The right-angle motor 10 functions as a power output. Inside the lifting frames 1 below the right-angle motor 10, threaded rods 11 are movably installed, and the output ends of the right-angle motors 10 are all connected to the threaded rods 11. Threaded blocks 12 are sleeved on the surfaces of the threaded rods 11, and the threaded rods 11 are all threadedly connected to the threaded blocks 12. Moreover, the threaded blocks 12 are all connected to the lifting conveyor 9. Inside the lifting frames 1 on one side of the threaded rods 11, sliding rods 28 are symmetrically installed. Sliding sleeves 29 are slidably installed on the surfaces of the sliding rods 28, and the sliding sleeves 29 are all connected to the lifting conveyor 9. Inside the lifting frames 1 below the lifting conveyor 9, second electric push rods 20 are symmetrically installed. The second electric push rods 20 function as power outputs. Electromagnets 22 are arranged outside the second electric push rods 20. The output ends of the second electric push rods 20 are all installed with adjusting rods 21, and the adjusting rods 21 are all connected to the electromagnets 22. Iron blocks 30 are installed on the outer walls of the multi-layer shelves 7 on one side of the electromagnets 22;

[0028] During use, the AGV cart 8 drives the multi-layer shelf 7 to move to one side of the lifting frame 1. The second electric push rod 20 is opened through the operation control panel 33. The adjusting rod 21 is driven to move by the second electric push rod 20, and the electromagnet 22 is driven to move by the adjusting rod 21. The electromagnet 22 is opened through the operation control panel 33, and the iron block 30 on the outer wall of the multi-layer shelf 7 is magnetically adsorbed by the electromagnet 22 to fix the entire multi-layer shelf 7 and prevent the multi-layer shelf 7 from shaking. The lifting conveyor 9 is opened through the operation control panel 33. The second conveyor belt 32 is driven to move by the lifting conveyor 9, and the materials are driven by the second conveyor belt 32 to move into the multi-layer shelf 7. The right-angle motor 10 is opened through the operation control panel 33. Supported by the lifting frame 1, the threaded rod 11 is driven to rotate by the right-angle motor 10. Under the threaded support of the threaded rod 11 and the threaded block 12, the threaded block 12 moves on the surface of the threaded rod 11. Supported by the sliding of the sliding rod 28 and the sliding sleeve 29, the entire lifting conveyor 9 is driven by the threaded block 12 to adjust the height. The support plate 14 is driven to adjust the height by the lifting conveyor 9, so that the support plate 14 drives the push plate 18 to adjust to one side of the material through the sliding plate 17. The first electric push rod 15 is opened through the operation control panel 33. The telescopic rod 16 is driven to move by the first electric push rod 15. Supported by the sliding of the sliding plate 17 and the support plate 14, the sliding plate 17 is driven to move by the telescopic rod 16, and the push plate 18 is driven to move by the sliding plate 17. Supported by the movable support of the hinge shaft 19, the materials are stacked in sequence by the push plate 18 to make the materials completely enter the multi-layer shelf 7. Through the same operation, multiple groups of materials are made to enter the multi-layer shelf 7. Since the lowest point of the push plate 18 is the same as the highest point of the materials, when the materials move on one side of the push plate 18, the push plate 18 rotates counterclockwise. When the push plate 18 is tilted at a certain angle, the materials can smoothly be conveyed from the second conveyor belt 32 into the multi-layer shelf 7. Due to the length limitation of the second conveyor belt 32, the materials cannot be completely sent into the multi-layer shelf 7. At this time, the operation control panel 33 is operated to open the first electric push rod 15, and the first electric push rod 15 controls the push plate 18 to completely convey the materials. When the first electric push rod 15 is required to drive the next group of materials to move, at this time, the first electric push rod 15 drives the push plate 18 to move to the left. When the push plate 18 moves to the left and touches the materials on the surface of the second conveyor belt 32, the push plate 18 rotates counterclockwise and moves to the leftmost side. Under the action of gravity, the push plate 18 rotates clockwise and vertically downward to facilitate driving another group of materials to move. The hinge shaft 19 is installed on the right side of the push plate 18. When the push plate 18 is vertically downward, the clockwise rotation of the push plate 18 is interfered and cannot rotate. After the multi-layer shelf 7 is filled with materials, the electromagnet 22 is closed through operation to make the magnetic adsorption of the electromagnet 22 on the iron block 30 disappear, which facilitates the AGV cart 8 to drive the multi-layer shelf 7 to move to the designated position, realizing the convenient height-adjustable material conveying of the feeding equipment, facilitating the sequential stacking of materials, and facilitating the magnetic adsorption fixation.Improves the convenience of mobile loading of loading equipment;

[0029] A support arm 23 is symmetrically installed inside the straightening frame 3, and support rods 27 are symmetrically installed on the outer wall of the support arm 23, and the support rods 27 are all connected to the straightening frame 3. A straightening plate 26 is arranged inside the straightening frame 3 on one side of the support arm 23, and the straightening plate 26 is slidably connected to the two groups of support rods 27. A third electric push rod 24 is symmetrically and movably installed on the top of the straightening frame 3 on one side of the support arm 23. The third electric push rod 24 plays a role in power output. A connecting rod 25 is installed at the output end of the third electric push rod 24, and the connecting rod 25 is movably connected to the straightening plate 26 through the support arm 23. A control panel 33 is installed on the outer wall of the lifting frame 1, and the output end of the control panel 33 is electrically connected to the input end of the belt conveyor 2, the fork arm lift 4, the lifting conveyor 9, the right-angle motor 10, the first electric push rod 15, the second electric push rod 20, the electromagnet 22, and the third electric push rod 24;

First, the staff uses a forklift 5 to transport multiple groups of placement plates 6 with materials to the top of the forkarm lift 4, and opens the forkarm lift 4 by operating the control panel 33. The forkarm lift 4 drives the multiple groups of placement plates 6 to adjust the height so that the materials at the top of the forkarm lift 4 are always kept flush with the belt conveyor 2, which is convenient for the staff to carry out hand-push loading. The staff places two groups of materials on the top of the two groups of first conveyor belts 31, and opens the belt conveyor 2 by operating the control panel 33. The belt conveyor 2 drives the first conveyor belt 31 to move, and the first conveyor belt 31 transports the materials at the top. The staff places the empty placement plates 6 on one side of the forkarm lift 4 for convenience afterwards For recycling, when the first conveyor belt 31 drives the material to be transported to the bottom of the straightening frame 3, the third electric push rod 24 is opened by operating the control panel 33. Under the support of the straightening frame 3, the third electric push rod 24 drives the connecting rod 25 to move. Under the sliding support of the straightening plate 26 and the support rod 27, the connecting rod 25 drives the straightening plate 26 to slide on the surface of the support rod 27, so as to facilitate the straightening plate 26 to carry out mobile straightening of the conveyed material, prevent the material from running off the track, and facilitate the material to smoothly enter the top of the second conveyor belt 32, realizing the convenient semi-automatic employee hand-pushing fast feeding of the feeding equipment, facilitating the formal conveying of the material, preventing the material from running off the track, improving the feeding efficiency, and reducing the labor intensity of the employees.

[0031] Working principle: When in use, an external power supply is connected.

The fork arm lift 4 drives the multiple sets of placement plates 6 to adjust their heights so that the materials at the top of the fork arm lift 4 are always kept flush with the belt conveyor 2, which is convenient for the staff to carry out hand-pushing loading. The staff places two sets of materials on the top of the two sets of first conveyor belts 31. The belt conveyor 2 drives the first conveyor belt 31 to move, and the first conveyor belt 31 transports the materials at the top. The staff places the empty placement plates 6 on the fork arm lift 4. When the first conveyor belt 31 drives the material to be transported to the bottom of the straightening frame 3, the third electric push rod 24 drives the connecting rod 25 to move, and the connecting rod 25 drives the straightening plate 26 to slide on the surface of the support rod 27, so as to facilitate the straightening plate 26 to perform mobile straightening of the conveyed material to prevent the material from running off the track, and facilitate the material to smoothly enter the top of the second conveyor belt 32. Then, the AGV trolley 8 drives the multi-layer shelf 7 to move to one side of the lifting frame 1, and the second electric push rod 20 drives the adjusting rod 21 to move, and the adjusting rod 21 drives the electromagnet 22 to move The electromagnet 22 magnetically adsorbs the iron block 30 on the outer wall of the multi-layer shelf 7 to fix the multi-layer shelf 7 as a whole to prevent the multi-layer shelf 7 from shaking. The lifting conveyor 9 drives the second conveyor belt 32 to move, and the second conveyor belt 32 drives the material to move to the inside of the multi-layer shelf 7. The right-angle motor 10 drives the threaded rod 11 to rotate, and the threaded block 12 moves on the surface of the threaded rod 11. The threaded block 12 drives the lifting conveyor 9 as a whole to adjust the height, and the lifting conveyor 9 drives the support plate 14 to adjust the height, so that the support plate 14 drives the push plate 11 through the sliding plate 17. 8 is adjusted to one side of the material, the telescopic rod 16 is driven by the first electric push rod 15 to move, the telescopic rod 16 drives the sliding plate 17 to move, the sliding plate 17 drives the push plate 18 to move, and the push plate 18 stacks the materials in sequence to make the materials completely enter the interior of the multi-layer shelf 7, and the same operation is performed to make multiple groups of materials enter the interior of the multi-layer shelf 7. When the multi-layer shelf 7 is full of materials, the electromagnet 22 is closed by operating the electromagnet 22 to make the magnetic adsorption of the electromagnet 22 on the iron block 30 disappear, so as to facilitate the AGV trolley 8 to drive the multi-layer shelf 7 to move to the specified position, so as to complete the use of the loading equipment.
