Detailed implementation manner

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0042] Embodiment:

[0043] Please refer to Figures 1 - 10, the present invention provides a technical solution: an automatic sheet metal discharging and conveying mechanism, including a conveyor belt 1 and a clamping frame 2. A sheet metal body 3 is arranged between two adjacent clamping frames 2. The sheet metal body 3 is an I-shaped sheet metal part. A bearing mechanism is arranged in the clamping frame 2. The bearing mechanism can intermittently discharge the sheet metal body 3 between two adjacent clamping frames 2 onto the conveyor belt 1. The bearing mechanism includes a first support block 7, a second support block 8 and a first inclined block 12. Both the first support block 7 and the second support block 8 are in contact with the lower surface of the sheet metal body 3. Before the discharging starts, the lowermost layer of the sheet metal body 3 is located on the first support block 7. The first support block 7 and the second support block 8 together provide support for the sheet metal body 3 between the clamping frames 2. The first support block 7 is in sliding contact with the first inclined block 12. A through hole 5 matching the first support block 7 is formed through the bottom end of the clamping frame 2, and it cooperates with the second support block 8 to intermittently discharge the sheet metal body 3. During discharging, the first support block 7 drives the lowermost layer of the sheet metal body 3 to move down to the conveyor belt 1 through the through hole 5. When the first support block 7 moves down, the second support block 8 moves horizontally out of the through hole 5 to provide a support point for the penultimate layer of the sheet metal body 3, preventing the lowermost layer of the sheet metal body 3 from moving down, so as to ensure that only one sheet metal body 3 moves down each time.

[0044] In this embodiment, a first fixed frame 9, a first motor 10, a second fixed frame 11 and a limit post 16 are respectively and fixedly installed in the clamping frame 2. A first connecting column 17 is movably installed in the first fixed frame 9. The bottom end of the first connecting column 17 is fixedly installed with a first hinge seat 20. The first hinge seat 20 is fixedly connected to the top end of the first support block 7. A second fixed column 25 is fixedly installed in the second fixed frame 11. The second fixed column 25 passes through the second support block 8. The first support block 7 is located between two adjacent telescopic second support blocks 8. The length of the first support block 7 is greater than the length of the second support block 8.

[0045] In this embodiment, a second rotating column 24 is fixedly installed in the second fixing frame 11. A second rotating gear 26 and a counterweight 30 are fixedly installed on the outer side of the second rotating column 24 through a connecting rope. Before the second rotating column 24 rotates, the connecting rope is in a bent state. When the first supporting block 7 contacts the first inclined block 12, the connecting rope is in a taut state. At the same time, a through hole through which the connecting rope passes is formed through the inside of the first connecting column 17. The counterweight 30 is located above the first supporting block 7. When the first supporting block 7 moves downward, the counterweight 30 can prevent the first supporting block 7 from tilting through the first hinge seat 20. The connecting rope is located on the surface of the limiting column 16 and slides through the limiting column 16. At the same time, the counterweight 30 slides in the inner wall of the clamping frame 2 to prevent the counterweight 30 from tilting up. A rack column 43 is fixedly installed at the top end of the second supporting block 8. The second rotating gear 26 is meshed with the rack column 43. When the second rotating gear 26 rotates, it can drive the second supporting block 8 to slide on the second fixing column 25 through the rack column 43, so that the second supporting block 8 moves horizontally to support the sheet metal part body 3, and the mutual separation between the two lowest sheet metal part bodies 3 is completed, and the intermittent discharging of the sheet metal part body 3 is completed.

[0046] In this embodiment, a first lead screw 13 and a first rotating column 15 are movably installed in the first fixing frame 9 respectively. The first motor 10 and the first lead screw 13 are meshed and connected through two mutually meshing bevel gears, so that the first motor 10 can drive the first lead screw 13 to rotate through the two bevel gears. A moving plate 14 is threadedly connected to the outer side of the first lead screw 13. The first motor 10 is a forward and reverse motor. A second motor for providing power is arranged on the sheet metal conveyor belt 1. A controller is arranged between the first motor 10 and the second motor. When the first motor 10 rotates in reverse, the second motor will not work. Second connecting columns 19 and third connecting columns 23 are fixedly installed at the bottom end of the moving plate 14 respectively. The third connecting column 23 is movably connected to the first connecting column 17. A first rotating gear 21 is fixedly installed on the outer side of the first rotating column 15. Two tooth block parts are arranged on the outer side of the second connecting column 19. The second connecting column 19 is meshed with the first rotating gear 21 and the second rotating gear 26 respectively through the tooth block parts. The tooth block parts on the second connecting column 19 drive the transmission belt 22 to rotate through the first rotating gear 21 respectively, and drive the second supporting block 8 to move horizontally through the second rotating gear 26.

[0047] On the second connecting column 19, there are two tooth block parts. When the upper tooth block part moves down along with the second connecting column 19, it will not engage with the first rotating gear 21 at the beginning. Only when the first support block 7 moves down and contacts the first inclined block 12, the upper tooth block part will engage with the first rotating gear 21. At this time, the cleaning brush 6 is located at the side of the sheet metal part body 3 above the first support block 7. And when the lower tooth block part moves down a certain distance along with the second connecting column 19, that is, when the lowermost sheet metal part body 3 moves by the thickness of one sheet metal part body 3, the lower tooth block part will engage with the second rotating gear 26.

[0048] When discharging the sheet metal part body 3 intermittently, first, the first motor 10 and the first lead screw 13 drive the moving plate 14 to move down. When the moving plate 14 moves down, it will drive the first support block 7 to move down through the third connecting column 23 and the first connecting column 17 respectively. The first support block 7 will drive the lowermost sheet metal part body 3 to move down. The counterweight 30 will ensure the balance of the first support block 7. At the same time, the moving plate 14 will also drive the second connecting column 19 to move down. When the second connecting column 19 moves down, it will drive the second rotating gear 26 to rotate. When the second rotating gear 26 rotates, it will drive the second support block 8 to move horizontally out of the through hole through the rack column 43 and insert under the second-lowermost sheet metal part body 3 to prevent the second-lowermost sheet metal part body 3 and the sheet metal part bodies 3 above it from moving down and provide a support point for them. As one side of the first support block 7 contacts the first inclined block 12 and the second connecting column 19 continues to move down, while the first connecting column 17 will not move down and stops moving, the second connecting column 19 will drive the first support block 7 to rotate and tilt around the first hinge seat 20. At the same time, the sheet metal part body 3 located on the first support block 7 will continue to move down and be placed on the conveyor belt 1 by the first support block 7. When the first motor 10 rotates in reverse, the second motor will be started simultaneously. The conveyor belt 1 will rotate, and through the partition 4, it will ensure the transportation of the sheet metal part body 3. The first connecting column 17 will move up along with the moving plate 14. At the same time, the first support block 7 will move up. And when the second connecting column 19 moves up, it will drive the second support block 8 to slowly withdraw from under the sheet metal part body 3 through the second rotating gear 26 until the first support block 7 contacts the sheet metal part body 3 again. Repeating this process, the intermittent discharging of the sheet metal part body 3 is achieved.

[0049] In this embodiment, a first fixing column 18 and a second inclined block 27 are fixedly installed in the first fixing frame 9 respectively. The moving plate 14 passes through the first fixing column 18. The second inclined block 27 is in sliding contact with the outer side of the first connecting column 17. A sliding strip 32 is fixedly installed on the side of the third connecting column 23. A connecting groove 29 is formed in the first fixing column 18. The sliding strip 32 is located in the connecting groove 29. The shape of the connecting groove 29 is S-shaped. When the moving plate 14 moves downward, it will drive the third connecting column 23 to move downward, and the sliding strip 32 on the side of the third connecting column 23 will move in the connecting groove 29. When the first connecting column 17 stops moving, the sliding strip 32 will adjust its moving direction in the connecting groove 29, so that the first connecting column 17 does not move, while the third connecting column 23 will retract into the first connecting column 17, avoiding interfering with the stopped state of the first connecting column 17 when the moving plate 14 moves downward through the third connecting column 23.

[0050] In this embodiment, a sliding groove 31 is formed in the first connecting column 17. The third connecting column 23 is located in the sliding groove 31. An adjusting frame 28 is fixedly installed on the outer side of the first connecting column 17. A first compression spring 34 is fixedly installed in the adjusting frame 28. One end of the first compression spring 34 is fixedly installed with a plugging column 33. The plugging column 33 passes through the first connecting column 17 and extends into the sliding groove 31 to contact the third connecting column 23. At the same time, the plugging column 33 is located below the third connecting column 23, preventing the third connecting column 23 from shifting in the sliding groove 31 before reaching the specified position.

[0051] In this embodiment, a first inclined edge that matches each other is provided between the second inclined block 27 and the plugging column 33, and they are in sliding contact through the first inclined edge, facilitating the second inclined block 27 to make the plugging column 33 extend out of the sliding groove 31. The connection design of the third connecting column 23 and the first connecting column 17, through the S-shaped shape of the connecting groove 29 and the cooperation of the sliding strip 32, during the downward movement of the moving plate 14, when the first connecting column 17 stops moving, the sliding strip 32 adjusts its moving direction in the connecting groove 29, so that the first connecting column 17 does not move, while the third connecting column 23 will retract into the first connecting column 17, avoiding interfering with the stopped state of the first connecting column 17 when the moving plate 14 moves downward.

[0052] The design of the adjusting frame 28 on the outer side of the first connecting column 17, the first compression spring 34 and the plugging column 33 therein prevents the third connecting column 23 from shifting in the sliding groove 32 before reaching the specified position. At the same time, under the action of the second inclined block 27, the plugging column 33 can extend out of or retract into the sliding groove 31, ensuring the smooth progress of the discharging process.

[0053] During use, when the moving plate 14 moves downward and the first connecting column 17 stops moving, the second inclined block 27 will contact the ground-inserting column 33. As the moving plate 14 continues to move downward, the second inclined block 27 causes the inserting column 33 to extend out of the sliding groove 31 through the first inclined edge, and squeezes the first compression spring 34. At the same time, the third connecting column 23 enters the sliding groove 31, so that the downward movement of the moving plate 14 will not interfere with the first connecting column 17; conversely, when the second inclined block 27 disengages from the inserting column 33, under the release of the elastic force of the first compression spring 34, the inserting column 33 will contact the third connecting column 23 again, and the third connecting column 23 disengages from the sliding groove 31.

[0054] Please refer to Figures 10 - 14 In this embodiment, a connecting block 38 is fixedly installed at the bottom end of the clamping frame 2. A second lead screw 36 and a sliding rod 39 are respectively arranged between adjacent two connecting blocks 38. A transmission belt 22 is arranged outside the first rotating column 15. The transmission belt 22 is movably connected to the end of the second lead screw 36. A moving block 35 is threadedly connected to the outside of the second lead screw 36. A cleaning brush 6 is arranged between adjacent two moving blocks 35. The sliding rod 39 passes through the cleaning brush 6, and the sliding rod 39 is inclined. When the cleaning brush 6 contacts the first support block 7 and the first inclined block 12, the bottom end surface of the cleaning brush 6 just contacts the upper surface of the sheet metal part body 3. As the sheet metal part body 3 moves downward, and the cleaning brush 6 moves along the sliding rod 39, the cleaning brush 6 will always clean the sheet metal part body 3 as the sheet metal part body 3 moves downward.

[0055] In this embodiment, a connecting mechanism is arranged between the moving block 35 and the cleaning brush 6. The connecting mechanism includes a second hinge seat 40 and a connecting cylinder 37. A sliding column 41 and a second compression spring 42 are respectively movably installed in the connecting cylinder 37. One end of the sliding column 41 is fixedly connected to the second hinge seat 40. The cleaning brush 6 needs to move downward with the sheet metal part body 3, and the moving directions of the cleaning brush 6 and the moving block 35 will be different.

[0056] In this embodiment, partitions 4 are arranged at equal intervals on the conveyor belt 1. The sheet metal part body 3 is located between adjacent two partitions 4.

[0057] When the second connecting column 19 moves downward, it will drive the first rotating gear 21 to rotate through the tooth block part. When the first rotating gear 21 rotates, it will drive the second lead screw 36 to rotate through the first rotating column 15 and the transmission belt 22. When the second lead screw 36 rotates, the moving block 35 will drive the cleaning brush 6 to clean the surface of the sheet metal part body 3 through the connecting mechanism. When the moving block 35 and the cleaning brush 6 move simultaneously, the cleaning brush 6 will extend the distance between the connecting cylinder 37 and the sliding column 41 and the moving block 35, and at the same time, change the inclination angle through the second hinge seat 40, so that the moving block 35 can still drive the cleaning brush 6 to always be located on the surface of the sheet metal part body 3 through the connecting mechanism during movement, and at the same time clean the surface of the sheet metal part body 3.

[0058] During the discharging process, the downward movement of the second connecting column 19 will drive the first rotating gear 21 to rotate through the tooth block part, and then drive the second lead screw 36 to rotate through the first rotating column 15 and the transmission belt 22, so that the moving block 35 drives the cleaning brush 6 to clean the surface of the sheet metal part body 3 through the connecting mechanism.

[0059] The design of the connecting cylinder 37, the sliding column 41 and the second compression spring 42 in the connecting mechanism enables the cleaning brush 6 to extend the distance between the connecting cylinder 37 and the sliding column 41 and the moving block 35 as the sheet metal part body 3 moves downward, and change the inclination angle through the second hinge seat 40, and always be located on the surface of the sheet metal part body 3 for cleaning, improving the quality of the sheet metal part.

[0060] Working principle of this embodiment: First, the first motor 10 and the first lead screw 13 drive the moving plate 14 to move downward. When the moving plate 14 moves downward, it will drive the first support block 7 to move downward through the third connecting column 23 and the first connecting column 17 respectively. The first support block 7 will drive the sheet metal part body 3 at the bottom layer to move downward. The counterweight 30 will ensure the balance of the first support block 7. At the same time, the moving plate 14 will also drive the second connecting column 19 to move downward. When the second connecting column 19 moves downward, it will drive the second rotating gear 26 to rotate. When the second rotating gear 26 rotates, it will drive the second support block 8 to move horizontally out of the through hole through the rack column 43 and insert it under the sheet metal part body 3 at the second-to-last layer to prevent the sheet metal part body 3 at the second-to-last layer and the sheet metal part bodies 3 above it from moving downward and provide a support point for them. As one side of the first support block 7 contacts the first inclined block 12 and the second connecting column 19 continues to move downward, while the first connecting column 17 will not move downward and stops moving, the second connecting column 19 will drive the first support block 7 to rotate and tilt around the first hinge seat 20. At the same time, the sheet metal part body 3 located on the first support block 7 will continue to move downward and be placed on the conveyor belt 1 by the first support block 7. When the first motor 10 rotates in reverse, the second motor will be started simultaneously, the conveyor belt 1 will rotate, and the transportation of the sheet metal part body 3 will be ensured through the partition 4. The first connecting column 17 will move upward with the moving plate 14. At the same time, the first support block 7 will move upward. Moreover, when the second connecting column 19 moves upward, it will drive the second support block 8 to slowly withdraw from under the sheet metal part body 3 through the second rotating gear 26 until the first support block 7 contacts the sheet metal part body 3 again. By repeating this process, intermittent discharging of the sheet metal part body 3 is achieved.

[0061] When the second connecting column 19 moves downward, it will drive the first rotating gear 21 to rotate through the tooth block part. When the first rotating gear 21 rotates, it will drive the second lead screw 36 to rotate through the first rotating shaft 15 and the transmission belt 22. When the second lead screw 36 rotates, the moving block 35 will drive the cleaning brush 6 to clean the surface of the sheet metal part body 3 through the connecting mechanism. When the moving block 35 and the cleaning brush 6 move simultaneously, the cleaning brush 6 will extend the distance between the connecting cylinder 37 and the sliding column 41 and the moving block 35, and at the same time, it will change the inclination angle through the second hinge seat 40, so that when the moving block 35 moves, it can still drive the cleaning brush 6 to always be on the surface of the sheet metal part body 3 through the connecting mechanism and clean the surface of the sheet metal part body 3 at the same time.

[0062] Only some exemplary embodiments of the present invention have been described by way of illustration. Without doubt, for those of ordinary skill in the art, various different ways can be used to modify the described embodiments without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
