[0015] In summary, the present invention includes the following beneficial technical effects:

[0016] 1. The present invention sets components such as a top pressure frame, a top pressure wheel, an inner toothed belt, a hanging block, a top plate and an elastic support plate, and controls the inner toothed belt to rotate counterclockwise. The lever applies a rightward thrust to the force-bearing elastic plate, drives the transmission frame and the door frame to push the pusher frame through an elastic connection first, and the elastic resistance plate first applies resistance to the pusher frame. The door frame first approaches the pusher frame, and after the elastic support plate is inserted into the groove-shaped structure of the pressure plate, the top plate is gradually pushed to rotate to a vertical state, and the horizontal toothed plate, the vertical plate and the hanging block are pushed downward by the pressure plate, so as to push the inner toothed belt to engage with the driven gear. When the inner toothed belt continues to rotate, the meshing belt with the driven gear is engaged. The movable top pressure wheel rotates, and the top pressure wheel pushes the sheet metal plate in contact with it upward when it rotates. When the elastic resistance plate is subjected to sufficient thrust, it elastically bends and is dislocated from the pusher rack. Then, after the sheet metal plate pushed upward by the top pressure wheel is disengaged from the top pressure wheel, the pressure plate is driven to move rightward relative to the top plate, so that the top plate gradually resumes its inclination. The vertical plate is reset upward under the elastic action of the movable block, and the hanging block is pulled upward, driving the corresponding part of the inner toothed belt to pull upward and disengage from the driven gear. Then, when the pusher rack moves to the right, it pushes the upper end of the sheet metal plate to tilt to the right, and then the sheet metal plate slides out from the left end of the three-dimensional storage box under the action of gravity.

[0017] 2. The present invention sets a torsion gear, a conveying wheel and an auxiliary material belt. The sheet metal plate moves upward and disengages from the top pressure wheel. After the vertical plate drives the horizontal tooth plate to move upward, the pusher rack moves away from the door frame, and the torsion gear engages with the horizontal tooth plate to drive the conveying wheel and the auxiliary material belt to rotate clockwise. The pusher rack gradually pushes the sheet metal plate to tilt, and the auxiliary material belt assists in pushing the sheet metal plate downward by rotating and moving it out of the left end of the three-dimensional storage box.

[0018] 3. The present invention sets a movable end wheel, a fixed end wheel, an adjustable end wheel and a feeding belt. The fixed end wheel rotates with the fixed-axis rotating wheel, driving the feeding belt to rotate counterclockwise. As the number of sheet metal plates in the three-dimensional storage box gradually decreases, the top pressure frame gradually moves to the right, pulling the adjustable end wheel to gradually move upward, so that the feeding belt is straightened. When the sheet metal plate tilts downward and falls above the feeding belt, the counterclockwise rotating feeding belt rotates to assist in driving the lower end of the sheet metal plate to move to the left out of the three-dimensional storage box.

[0019] 4. The present invention provides small side wheels and large side wheels. When a new sheet metal plate needs to be added to the three-dimensional storage box, the new sheet metal plate is pushed downward from between the last sheet metal plate and the large side wheels into the three-dimensional storage box. The large side wheels and the small side wheels rotate to facilitate the insertion of the sheet metal plate into the three-dimensional storage box. BRIEF DESCRIPTION OF THE DRAWINGS

Figure 1-Figure 10As shown, it includes a three-dimensional storage box 1, a top pressure frame 2 is arranged inside the three-dimensional storage box 1, the front and rear ends of the top pressure frame 2 slide through the front and rear inner walls of the three-dimensional storage box 1 respectively, the top pressure frame 2 is elastically connected to the three-dimensional storage box 1, a plurality of small side wheels 29 are rotatably connected inside the right end of the three-dimensional storage box 1, a large side wheel 30 is rotatably connected inside the right end of the three-dimensional storage box 1, the large side wheel 30 is located above the small side wheel 29, the left side surface of the large side wheel 30 is tangent to the left side surface of the small side wheel 29, the lower end of the three-dimensional storage box 1 is rotatably connected to two horizontal wheels 39 arranged horizontally, the two horizontal wheels 39 are driven by a movable material belt 40, and the movable material belt 40 is located in the three-dimensional storage box When the sheet metal plate is inserted into the three-dimensional storage box 1, the sheet metal plate contacts the large side wheel 30, driving the large side wheel 30 to roll and be inserted between the large side wheel 30 and the adjacent sheet metal plate. The small side wheel 29 and the large side wheel 30 rotate to facilitate the insertion of the sheet metal plate into the three-dimensional storage box 1. The pushing rack 11 is located above the movable material belt 40. When the sheet metal plate moves inside the three-dimensional storage box 1, the sheet metal plate contacts the movable material belt 40 to drive the movable material belt 40 to move. The inner top wall of the movable material belt 40 is located between the two horizontal wheels 39 and is in contact with an auxiliary support plate 41. The auxiliary support plate 41 supports the movable material belt 40 to prevent the movable material belt 40 from sinking.

[0033] The right end of the pressing frame 2 is rotatably connected to the pressing wheel 3, and an auxiliary pressing wheel 38 is arranged on the lower side of the pressing wheel 3. The right side surface of the auxiliary pressing wheel 38 is tangent to the right side surface of the pressing wheel 3, and both ends of the auxiliary pressing wheel 38 are rotatably connected to the pressing frame 2. When the pressing frame 2 is elastically connected to the three-dimensional storage box 1, it drives the pressing wheel 3, the auxiliary pressing wheel 38 and the adjacent sheet metal plates to apply pressure to squeeze the multi-layer sheet metal plates tightly. A fixed-axis rotating wheel 4 and a movable rotating wheel 5 are arranged in front of the three-dimensional storage box 1. The fixed-axis rotating wheel 4 is rotatably connected to the lower left end of the three-dimensional storage box 1, and the front end of the movable rotating wheel 5 is rotatably connected to a bending telescopic rod 6, and the other end of the bending telescopic rod 6 is fixed to the right end of the three-dimensional storage box 1. The two movable rotating wheels 5 and the fixed-axis rotating wheel 4 are driven by an inner toothed belt 7. The bending telescopic rod 6 has a tendency to pull the movable rotating wheel 5 away from the fixed-axis rotating wheel 4, so that the inner toothed belt 7 is in a taut state.

[0034] A movable block 9 is slidably inserted into the front of the three-dimensional storage box 1, and a vertical plate 8 is slidably penetrated on the upper surface of the movable block 9. The front of the vertical plate 8 is elastically connected to the upper surface of the movable block 9, and a hanging block 10 is slidably sleeved on the upper end of the outer ring surface of the inner toothed belt 7. The upper surface of the hanging block 10 is fixed to the vertical plate 8. A pusher rack 11 is arranged inside the three-dimensional storage box 1 and above the top pressure rack 2. The front and rear ends of the pusher rack 11 both slide through the inner wall of the three-dimensional storage box 1. A door frame 12 is slidably sleeved on the upper end of the three-dimensional storage box 1. A cross bar 13 is slidably penetrated on the left side of the front and rear ends of the pusher rack 11. The left end of the cross bar 13 is fixed to the door frame 12. The door frame 12 is elastically connected to the pusher rack 11. The push rack 11 has a tendency to move away from each other under the elastic connection, the upper end of the vertical plate 8 is slidably sleeved with a horizontal tooth plate 15, the bottom surface of the horizontal tooth plate 15 is fixed with a vertical telescopic rod 14, the vertical telescopic rod 14 is fixed to the three-dimensional storage box 1, and the vertical telescopic rod 14 limits the moving trajectory of the horizontal tooth plate 15. The vertical plate 8 has a tendency to move up synchronously with the horizontal tooth plate 15. A pressure plate 16 is arranged above the horizontal tooth plate 15, and a tension telescopic rod 17 is fixed on the upper surface of the pressure plate 16. A torsion gear 26 is arranged above the horizontal tooth plate 15 and in front of the pressure plate 16. The internal rotation of the push rack 11 is connected to two conveying wheels 27, and the two conveying wheels 27 are staggered left and right. Two conveying wheels 27 are located inside the three-dimensional storage box 1, and the two conveying wheels 27 are driven by the auxiliary material belt 28. The torsion gear 26 is coaxially fixedly sleeved on the front end of the conveying wheel 27 located above. The auxiliary material belt 28 is set higher on the left and lower on the right. The upper end of the tension telescopic rod 17 is fixed to the pusher frame 11. The door frame 12 is located above the pressure plate 16. The right side of the door frame 12 is rotatably connected to the top plate 18. The lower end of the top plate 18 is fixed with an elastic support plate 19. The upper surface of the pressure plate 16 is a plurality of groove-shaped structures. The elastic support plate 19 is located inside a groove-shaped structure of the pressure plate 16. When the door frame 12 approaches the pusher frame 11, the top plate 18 moves relative to the pusher frame 11 by following the door frame 12. When the top plate 18 is in a vertical state, the torsion gear 26 is disengaged from the horizontal tooth plate 15. When the door frame 12 and the pushing frame 11 approach each other and the pushing frame 11 moves away from the door frame 12 again, the top plate 18 resumes its inclined state, causing the torsion gear 26 to engage with the horizontal tooth plate 15, driving the auxiliary material belt 28 to rotate clockwise. When the auxiliary material belt 28 rotates, it assists the sheet metal plate in contact with it to move downward.

[0035] A transmission frame 21 is fixed on the front of the door frame 12, and a double-rod synchronous plate 20 is arranged in front of the vertical plate 8. The lower end of the double-rod synchronous plate 20 is rotatably sleeved on the front end of the top pressure wheel 3, and one end of the vertical plate 8 located below the movable block 9 is slidably sleeved on the back of the double-rod synchronous plate 20. The left side of the double-rod synchronous plate 20 is a double-rod structure. The transmission frame 21 is slidably sleeved on the outer surface of the rod-shaped structure of the double-rod synchronous plate 20. The transmission frame 21 is elastically connected to the double-rod synchronous plate 20, and the transmission frame 21 has a tendency to move away from the double-rod synchronous plate 20. The inner top wall of the inner toothed belt 7 is meshed with a driven gear 22. The gear 22 corresponds to the hanging block 10 up and down. When the hanging block 10 moves downward, it can push the inner toothed belt 7 to mesh with the driven gear 22, so that when the inner toothed belt 7 rotates counterclockwise, it can drive the top pressure wheel 3 to rotate by meshing with the driven gear 22. During the rotation of the top pressure wheel 3, the sheet metal plate in contact with it is pushed upward. The driven gear 22 is coaxially fixedly sleeved on the front end of the top pressure wheel 3. A plurality of levers 23 are fixed on the front side of the inner toothed belt 7. A plurality of force-bearing elastic plates 24 are arranged in front of the inner toothed belt 7 and below the fixed-axis rotating wheel 4. The front end of the force-bearing elastic plate 24 is fixed to the transmission frame 21. The top plate 1 The distance between the connection between the upper end of 8 and the door frame 12 and the lower end of the door frame 12 is less than the length of the top plate 18, and the distance between each adjacent two force-bearing elastic plates 24 is different. A plurality of levers 23 are evenly distributed on the front side of the inner toothed belt 7. The outer ring surface of the inner toothed belt 7 is an annular convex strip structure. The hanging block 10 is adapted to the annular convex strip structure of the inner toothed belt 7. An elastic resistance plate 25 is provided on the right side of the front end of the pusher frame 11. The front end of the elastic resistance plate 25 is fixed to the upper end of the double-rod synchronous plate 20. Before the sheet metal plate moves upward, when the door frame 12 pushes the pusher frame 11 to the right, the elastic resistance plate 25 The movement of the pushing rack 11 generates resistance, causing the top plate 18 to rotate to a vertical state first, so that the top pressure wheel 3 can rotate to push the sheet metal plate upward. After the upper end of the sheet metal plate moves to above the lower end of the pushing rack 11, as the door frame 12 continues to move to the right, when the elastic resistance plate 25 is subjected to sufficient thrust, it elastically bends and is misaligned with the pushing rack 11, causing the pushing rack 11 to contact the sheet metal plate. Then, after the sheet metal plate pushed upward by the top pressure wheel 3 is separated from the top pressure wheel 3, the pushing rack 11 pushes the upper end of the sheet metal plate to tilt to the right when it moves to the right, and at the same time, the auxiliary material belt 28 rotates to assist in pushing the sheet metal plate downward.

[0036] The upper surface of the top pressure frame 2 is set to be lower on the left and higher on the right. A movable end wheel 31 is rotatably installed inside the top pressure frame 2 and located on the left side of the top pressure wheel 3. A fixed end wheel 32 is set on the left side of the movable end wheel 31. Both ends of the fixed end wheel 32 are rotatably connected to the left end of the three-dimensional storage box 1. An adjusting end wheel 33 is set below the fixed end wheel 32. The fixed end wheel 32 is coaxially fixed with the fixed-axis rotating wheel 4. A motor that provides power to the fixed end wheel 32 and the fixed-axis rotating wheel 4 is installed on the back of the three-dimensional storage box 1. Both ends of the adjusting end wheel 33 are rotatably connected with blocks 34. The outer surface of each block 34 is slidably sleeved with a vertical frame 35. The upper end of the vertical frame 35 is fixed to the left end of the three-dimensional storage box 1, and the block 34 is elastically connected to the inner wall of the vertical frame 35. The adjusting end wheel 33, the movable end wheel 31 and the fixed end wheel 3 2 is transmitted by the feeding belt 36. At the same time, the feeding belt 36 is tightened under the elastic connection between the block 34 and the vertical frame 35. When the sheet metal plate tilts downward and falls above the feeding belt 36, the feeding belt 36 rotates counterclockwise to assist in driving the lower end of the sheet metal plate to move leftward out of the three-dimensional storage box 1. The feeding belt 36 is distributed in a triangular shape. The upper surface of the feeding belt 36 is set to be lower on the left and higher on the right. A positioning wheel 37 is set on the right side of the feeding belt 36. Both ends of the positioning wheel 37 are rotatably connected to the three-dimensional storage box 1. When the top pressure frame 2 drives the right end of the feeding belt 36 to move rightward, the right side of the feeding belt 36 gradually forms a quadrilateral under the obstruction of the positioning wheel 37, ensuring that the right side of the feeding belt 36 entering the three-dimensional storage box 1 will not contact and rub with the three-dimensional storage box 1 to cause wear.

[0037] The working principle is as follows: the stored sheet metal plates are placed in multiple layers on the right side of the top pressure frame 2 inside the three-dimensional storage box 1. The top pressure frame 2 pushes the top pressure wheel 3 to press the sheet metal plates under the elastic connection with the three-dimensional storage box 1. The bending telescopic rod 6 drives the inner toothed belt 7 to tighten by pulling the movable rotating wheel 5. When the sheet metal plates need to be taken out, the fixed axis rotating wheel 4 drives the inner toothed belt 7 to rotate counterclockwise, and the lever 23 moves with the inner toothed belt 7. The lever 23 located below the axis of the inner toothed belt 7 moves to the right, and then applies a rightward thrust to the stressed elastic plate 24. , driving the transmission frame 21 and the door frame 12 to push the pusher frame 11 through the elastic connection first, the elastic resistance plate 25 first applies resistance to the pusher frame 11, and when the door frame 12 moves to the right, the door frame 12 first approaches the pusher frame 11, so that the top plate 18 drives the elastic support plate 19 to move to the right relative to the pressure plate 16, and after the elastic support plate 19 is inserted into the groove-shaped structure of the pressure plate 16, the top plate 18 is gradually pushed to rotate to a vertical state, and the horizontal toothed plate 15, the vertical plate 8 and the hanging block 10 are pushed downward through the pressure plate 16, pushing the inner toothed belt 7 and the driven gear 22 meshes, and when the inner toothed belt 7 continues to rotate, it meshes with the driven gear 22 to drive the top pressure wheel 3 to rotate. When the top pressure wheel 3 rotates, it pushes the sheet metal plate in contact with it upward. After the sheet metal plate moves upward to a certain height, the door frame 12 drives the pusher frame 11 to apply a thrust to the elastic resistance plate 25 to gradually increase through the elastic connection. When the elastic resistance plate 25 is subjected to sufficient thrust, it elastically bends and is misaligned with the pusher frame 11, so that the auxiliary material belt 28 contacts the sheet metal plate moving upward, and then the sheet metal plate pushed upward by the top pressure wheel 3 is pushed upward. After the sheet metal plate is separated from the top pressure wheel 3, the push rack 11 moves away from the door frame 12 under the elastic connection with the door frame 12, driving the pressure plate 16 to move rightward relative to the top plate 18, so that the top plate 18 gradually resumes its inclination, and the vertical plate 8 is reset upward under the elastic action of the movable block 9, pulling the hanging block 10 to move upward, driving the corresponding part of the inner toothed belt 7 to pull upward and disengage from the driven gear 22, and then the push rack 11 moves to the right, pushing the upper end of the sheet metal plate to tilt to the right, and then the sheet metal plate slides out from the left end of the three-dimensional storage box 1 downward under the action of gravity.

[0038] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
