Description

Technical Field

[0001] This utility model belongs to the field of metal sheet transportation technology, and specifically relates to a metal sheet lifting machine. Background Technology

[0002] Metal sheet processing elevators are mechanical equipment specifically designed for the vertical conveying of metal sheets. They are widely used in metal stamping, cutting, welding and other processes. They improve production efficiency through efficient and stable material transfer. Their core function is to transport metal sheets from a low position to the processing platform or storage area, reducing manual handling costs and ensuring the continuity of the processing flow.

[0003] The current elevators work by stacking overlapping metal sheets on top and using suction cups to pick up the top sheet, thus transporting it to another processing device. A horizontal plate is located below the metal sheets, and a screw connected to the elevator is mounted on the bottom of the plate. When the screw rotates forward, it moves the horizontal plate upward; when it rotates in the reverse direction, it moves the plate downward, thereby lifting the metal sheets. To ensure the stability of the metal sheets stacked on the top of the horizontal plate and prevent them from tipping to one side, the elevator has four stops that can surround the metal sheets. However, the positions of the four stops are fixed by nuts. When lifting metal sheets of different diameters, the positions of the four stops need to be adjusted separately. The nut fixing method makes the adjustment process complicated and cannot guarantee that the adjustment distances of the four stops are equal. Utility Model Content

[0004] The purpose of this invention is to provide a metal sheet lifting machine to solve the problems existing in the background art.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A metal sheet lifting machine includes a support frame with an installation groove on its side and an installation frame on its upper side. An installation plate is located on the upper side of the installation frame, and a through groove is located in the middle of the installation plate. A horizontal plate is located below the through groove. Vertical plates connected to the installation plate are located on both sides of the horizontal plate. A screw is threadedly connected to the middle of the horizontal plate, and the screw passes downward through the horizontal plate. The installation plate has a drive mechanism connected to the screw. A top plate is rotatably mounted on the upper side of the screw, and a stabilizing mechanism is mounted on the top plate. Four stop bars are slidably mounted on all four sides of the installation plate, and the four stop bars are evenly arranged in a ring around the center of the through groove. The four stop bars can slide towards the center of the through groove. The installation plate has a pulling mechanism that matches the four stop bars.

[0007] The pulling mechanism includes four sliding components and one pulling component. The four sliding components are respectively connected to four stop bars. Each sliding component includes a sliding groove on the upper side of the mounting plate. A slider is slidably mounted in the sliding groove. The stop bar is connected to the upper side of the slider. A spring-loaded component is mounted on the side of the slider away from the through groove. The pulling component can simultaneously pull the four sliders to slide away from the center of the through groove.

[0008] The rebound component includes two slide rods and two springs. The two slide rods are respectively located on the left and right sides of the through groove. The slider is sleeved on the outside of the slide rod on the same side on both the left and right sides. The two springs are respectively sleeved on the side of the two slide rods away from the through groove.

[0009] The pulling assembly includes pulling grooves respectively located on the left and right sides. Both of the left and right sliding grooves are provided with through holes communicating with the pulling grooves. Pull wires are provided in both of the pulling grooves. Each of the left and right pull wires is provided with two connecting wires. The two connecting wires pass through the two through holes on the same side and are connected to the slider. The mounting plate is provided with a winding part connected to the two pull wires.

[0010] The winding part is provided with a winding cavity located in the mounting plate. Both of the two pull grooves are connected to the winding cavity. A winding shaft is rotatably mounted in the winding cavity. Both of the pull wires are connected to the winding shaft. A handle is provided on the upper side of the winding shaft extending out of the mounting plate.

[0011] The winding shaft has an annular component on its upper side, the annular component has an inclined surface, the mounting plate has a fixing component on its upper side, the fixing component is threadedly connected to a threaded component pointing to the inclined surface, and the threaded component has a rotating component on its upper side.

[0012] The upper side of the inclined surface is provided with several anti-slip textures.

[0013] The stabilizing mechanism includes four limiting rods, which are respectively connected to the four corners of the top plate, and all four limiting rods slide downward through the horizontal plate.

[0014] Each of the four corners of the support frame is provided with a lead screw, and the outer surfaces of the four lead screws are slidably fitted with support plates connected to the mounting frame. The upper and lower sides of the four support plates are provided with nuts that are threadedly connected to the lead screws.

[0015] This utility model has the following technical advantages compared with the prior art:

[0016] 1. The drive mechanism rotates the screw to achieve automatic lifting and lowering of the top plate. As the metal sheets are continuously removed from the top, the drive mechanism synchronously drives the screw to rotate in the forward direction, causing the top plate to move continuously upward. This ensures a continuous supply of metal sheets to subsequent processing equipment, eliminating the need for frequent manual intervention in feeding and greatly improving the continuity and efficiency of the production process.

[0017] 2. The top plate lifting speed can be flexibly adjusted according to the metal sheet removal speed, which can be well matched with the operating rhythm of various processing equipment, avoiding equipment idleness due to untimely material supply or accumulation due to excessive supply, and ensuring stable overall production efficiency.

[0018] 3. Four stop levers are evenly arranged in a ring around the center of the through slot, and their positions can be adjusted simultaneously by a pulling mechanism. Regardless of the diameter of the circular metal sheet, the stop levers can be adjusted to ensure they tightly surround the four sides of the metal sheet, effectively preventing the metal sheet from shifting or slipping during lifting and ensuring that the metal sheet is stably overlapped on the upper side of the top plate.

[0019] 4. The four limit rods in the stabilizing mechanism are connected to the four corners of the top plate and pass through the horizontal plate. They precisely limit the movement of the top plate as it slides up and down, preventing the top plate from rotating with the screw and ensuring that the top plate only makes stable vertical movements. This further ensures the stability of the metal sheet placement and lifting.

[0020] 5. The pulling mechanism is ingeniously designed. Operators only need to turn the handle to drive the winding shaft to rotate, which will simultaneously pull the four sliders and achieve simultaneous and equidistant movement of the four stops. This operation method is simple and quick, and can quickly adjust the position of the stops according to metal sheets of different diameters, which greatly shortens the equipment adjustment time and improves the efficiency of production preparation.

[0021] 6. The screw rods at the four corners of the support frame cooperate with the support plate. By rotating the upper and lower two nuts, the height of the support plate can be easily adjusted, thereby adjusting the height of the mounting frame. This design enables the hoist to adapt to processing equipment and working environments of different heights, enhancing the versatility and flexibility of the equipment. Attached Figure Description

Detailed Implementation

[0032] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0033] like Figure 1-7 As shown, a metal sheet lifting machine of this utility model includes a support frame 1, a mounting groove 11 in the middle of the support frame 1, a mounting frame 12 on the upper side of the support frame 1, a mounting plate 13 on the upper side of the mounting frame 12, a through groove 14 in the middle of the mounting plate 13, a horizontal plate 2 on the lower side of the through groove 14, vertical plates 21 connected to the mounting plate 13 on both the left and right sides of the horizontal plate 2, a screw 22 threadedly connected to the middle side of the horizontal plate 2, the screw 22 passing downward through the horizontal plate 2, a drive mechanism 201 connected to the screw 22 in a transmission, a top plate 23 rotatably mounted on the upper side of the screw 22, a stabilizing mechanism mounted on the top plate 23, and four stops 24 slidably mounted on all four sides of the mounting plate 13, the four stops 24 being evenly arranged in a ring around the center of the through groove 14, the four stops 24 being able to slide towards the center of the through groove 14, and a pulling mechanism matching the four stops 24 on the mounting plate 13.

[0034] When it is necessary to lift the metal sheet upwards and transport it to another transfer processing device, the drive mechanism 201 can drive the screw 22 to rotate in the direction of rotation. When the screw 22 rotates in the opposite direction, since the screw 22 is threadedly connected to the horizontal plate 2, the screw 22 drives the top plate 23 to move downwards. When the top plate 23 moves downwards to the appropriate position, the metal sheets can be stacked on the top plate 23 one by one. The four side bars 24 surround the four sides of the metal sheets to block the stacked metal sheets and ensure that the metal sheets are stably overlapped on the top plate 23. At this time, the metal sheets are continuously removed from the top of the metal sheets by other transport equipment. At this time, the drive mechanism 201 follows the continuous removal of the metal sheets and continuously drives the screw 22 to rotate in the forward direction. The screw 22 moves upwards relative to the horizontal plate 2, thereby driving the top plate 23 to move upwards. The top plate 23 then drives the stacked metal sheets to move upwards continuously until all the stacked metal sheets have been removed from the top plate 23.

[0035] During the up-and-down sliding process of the top plate 23, the stabilizing mechanism can limit the top plate 23 to ensure the sliding stability of the top plate 23 and ensure that the top plate 23 will not rotate with the screw 22.

[0036] When it is necessary to adjust the position of the four levers 24 for metal sheets of different diameters, the operator can simultaneously move the four levers 24 away from the through groove 14 by pulling the mechanism. After the distance between the four levers 24 is adjusted to the appropriate position, the pulling mechanism is stopped, and the four levers 24 stop moving, thus completing the adjustment of the position of the four levers 24. Since the four levers 24 move at the same time and the moving distance is equal, it can be ensured that the four levers 24 are always adjusted according to the diameter of the metal sheet, ensuring that the four levers 24 can block the circular metal sheet.

[0037] The pulling mechanism includes four sliding components and one pulling component. The four sliding components are respectively connected to four stop levers 24. The sliding component includes a slide groove 3 on the upper side of the mounting plate 13. A slider 31 is slidably mounted in the slide groove 3. The stop lever 24 is connected to the upper side of the slider 31. A spring-loaded component is mounted on the side of the slider 31 away from the through groove 14. The pulling component can simultaneously pull the four sliders 31 to slide away from the center of the through groove 14.

[0038] When the operator needs to adjust the position of the four levers 24, the pulling component simultaneously pulls the four sliders 31 in the slide groove 3 to move away from the center of the through groove 14, causing the spring-loaded component to compress. When the pulling component is released from pulling the four sliders 31, the spring-loaded component extends and causes the sliders 31 to return to their original position in the slide groove 3, effectively achieving the purpose of adjusting the distance between the four levers 24 according to the diameter of the metal sheet.

[0039] The springback component includes two slide rods 32 and two springs 33. The two slide rods 32 are respectively located on the left and right sides of the through groove 14. The slider 31 is sleeved on the outside of the slide rods 32 on the same side on both the left and right sides. The two springs 33 are respectively sleeved on the side of the two slide rods 32 away from the through groove 14.

[0040] When the slider 31 moves away from the through groove 14, the slider 31 slides relative to the slide rod 32, and the spring 33 can be compressed. When the pulling of the slider 31 is released, the slider 31 can be reset under the action of the spring 33.

[0041] The pulling assembly includes pulling grooves 34 respectively located on the left and right sides. Both left and right sliding grooves 3 are provided with through holes 35 communicating with the pulling grooves 34. Pull wires 36 are provided in both pulling grooves 34. Both left and right pull wires 36 are provided with two connecting wires 37. The two connecting wires 37 pass through the two through holes 35 on the same side and are connected to the slider 31. The mounting plate 13 is provided with a winding part connected to the two pull wires 36.

[0042] When it is necessary to pull the slider 31, the winding part can pull the two pull wires 36 simultaneously, and the pull of the two pull wires 36 will pull the slider 31 through the connecting wire 37.

[0043] The winding section is provided with a winding cavity 4 located in the mounting plate 13. Two pull grooves 34 are connected to the winding cavity 4. A winding shaft 41 is rotatably mounted in the winding cavity 4. Two pull wires 36 are connected to the winding shaft 41. A handle 42 is provided on the upper side of the winding shaft 41 extending out of the mounting plate 13.

[0044] When the operator turns the handle 42, the winding shaft 41 starts to rotate, and the winding shaft 41 winds the pull wires 36 on both sides to achieve the purpose of pulling the two pull wires 36. The slider 31 can then be pulled through the connecting wire 37. When the handle 42 is turned in the opposite direction, the winding shaft 41 rotates in the opposite direction, canceling the winding of the pull wires 36, so that the slider 31 can be reset.

[0045] The upper side of the winding shaft 41 is provided with an annular part 43, the annular part 43 is provided with a slope 44, the upper side of the mounting plate 13 is provided with a fixing part 45, the fixing part 45 is threadedly connected to a threaded part 46 pointing to the slope 44, and the upper side of the threaded part 46 is provided with a rotating part 47.

[0046] When the winding shaft 41 no longer needs to be rotated, the operator rotates the rotating component 47, causing the threaded component 46 to move towards the inclined plane 44 until the threaded component 46 is in close contact with the inclined plane 44, which can limit the ring component 43. This prevents the winding shaft 41 from rotating. When the operator moves the threaded component 46 away from the inclined plane 44 by rotating the rotating component 47, the limitation on the ring component 43 can be removed, and the handle 42 can be rotated freely.

[0047] The upper side of the inclined surface 44 is provided with several anti-slip grooves. The anti-slip groove design can improve the friction between the threaded part 46 and the annular part 43.

[0048] The stabilizing mechanism includes four limit rods 5, which are connected to the four corners of the top plate 23 respectively, and all four limit rods 5 slide downward through the horizontal plate 2.

[0049] Each of the four corners of the support frame 1 is provided with a lead screw 51, and the outer surface of each of the four lead screws 51 is slidably fitted with a support plate 52 connected to the mounting frame 12. The upper and lower sides of each of the four support plates 52 are provided with a nut 53 that is threadedly connected to the lead screw 51.

[0050] This design allows for the rotation of the two nuts 53, effectively adjusting the height of the support plate 52. Since the support plate 52 is connected to the mounting frame 12, the height of the mounting frame 12 can also be adjusted.

[0051] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
