[0002] Loading and unloading devices are key equipment in industrial automation, production lines and logistics systems, used to efficiently and safely complete the loading, unloading, transportation or positioning of materials.

[0003] When loading and unloading materials from a vehicle, the conveyor belt on the bracket is moved closer to the vehicle, and the round rod on the bracket deforms the bracket so that one side of the bracket is inside the vehicle. The control motor is then started to drive the rotating roller to rotate, and the conveyor belt on the bracket is used to transport and load and unload the materials. During the loading and unloading process, the materials need to be continuously moved to the conveyor belt, and the operator needs to constantly lift the materials to a higher position, which results in excessive labor intensity for the operator, requiring longer rest time, and thus affecting the unloading efficiency. Summary of the Invention

The lifting and unloading device moves the lifting plate through the driving component to lift and move the material, and an auxiliary component is provided on one side of the lifting plate, and the auxiliary component limits the two sides of the lifting plate.

[0006] The effects achieved by the above components are as follows: when loading and unloading materials on a vehicle, the conveyor belt on the bracket will be moved near the vehicle, and the round rod on the bracket will deform the bracket so that one side of the bracket is inside the vehicle, and then the control motor will be started to drive the rotating roller to rotate, and then the conveyor belt on the bracket will be used to transport and load and unload the materials. When unloading, the lifting and unloading device will be inside the vehicle, and when loading, the lifting and unloading device will be outside the vehicle to lift the materials upward and send the materials to the surface of the conveyor belt. When using the lifting and unloading device, the auxiliary components will increase the use effect of some components of the lifting and unloading device.

At this time, the second rotating rod rotates on the connecting frame, and the second disc fixed to the second rotating rod and the second coil spring fixed between the connecting frame are deformed. Then the control frame squeezes the triangular block, causing the extension block fixed on one side of the triangular block to slide inside the extension groove on the surface of the lifting plate.

By lifting the unloading device, the material can be lifted upward and sent to the surface of the conveyor belt, avoiding the operator's need to constantly lift the material to a higher position, thereby reducing the operator's labor intensity and allowing the operator to work longer during working hours, thereby improving the efficiency of loading and unloading, and thereby improving the use effect of the loading and unloading device.

[0012] The effect achieved by the above components is as follows: when the fixing assembly is used, the blocking block passes through the first L-shaped plate fixed to the connecting frame and engages with the blocking groove on the first rotating rod to fix the position of the first rotating rod; when the position sensor detects that the control frame is close to the driving block and the first rotating rod needs to be rotated, the electric telescopic rod on the second L-shaped plate fixed to the first L-shaped plate is started, and then the blocking block fixed to the output end of the electric telescopic rod is disengaged from the blocking groove.

[0042] Reference Figure 1-10As shown, this embodiment discloses that after the material is placed on the lifting plate 67, the baffle 611 limits the rotation direction of the control frame 610, and the fixing component 68 fixes the position of the first rotating rod 64. Then, after the material is placed on the lifting plate 67, it will not drive the lifting plate 67 to rotate. Then, the driving component 62 on the fixed frame 61 fixed to the bracket 1 is started, and then the connecting frame 63 moves upward. Then, the connecting frame 63 drives the first rotating rod 64 rotating on the surface to drive the lifting plate 67 fixed to the first rotating rod 64 to move upward. Then, after the lifting plate 67 moves to a height higher than the conveyor belt 5, the fixing component 68 no longer fixes the first rotating rod 64, and then the driving component 62 fixed to the fixed frame 61 is started. The movable block 618 squeezes the control frame 610 fixed to the second rotating rod 69, causing the control frame 610 to tilt close to the triangular block 616.

After the extension block 615 reaches the maximum displacement, the control frame 610 causes the lifting plate 67 to tilt away from one side of the bracket 1. At this time, the first rotating rod 64 rotates on the connecting frame 63, and the first disc 65 fixed to the first rotating rod 64 and the first coil spring 66 fixed between the connecting frame 63 will be deformed. Then the material on the lifting plate 67 slides to the extension block 615 on the surface of the lifting plate 67. Then the material reaches the surface of the conveyor belt 5 to complete the lifting and unloading of the material. Then the driving assembly 62 is started to reset the connecting frame 63 to the lower end of the fixed frame 61. Then the driving block 618 is no longer in contact with the control frame 610. Then the second coil spring 612 resets the second rotating rod 69 to reset the control frame 610 Reset, then the second spring 617 brings the extension block 615 to reset, and the first coil spring 66 drives the first rotating rod 64 to reset to complete the reset of the lifting plate 67, and then the fixing component 68 re-fixes the first rotating rod 64 so that the first rotating rod 64 can no longer rotate, and then repeats the above operations to continuously transport the material to the surface of the conveyor belt 5. By lifting the unloading device 6, the material can be lifted upward and sent to the surface of the conveyor belt 5, avoiding the situation where the operator needs to constantly lift the material to a higher position, and then reducing the labor intensity of the operator, so that the operator can work for a longer time during working hours, thereby improving the efficiency of loading and unloading, and thus improving the use effect of the loading and unloading device.

[0043] Reference Figure 1-10As shown, this embodiment discloses that the driving component 62 includes a driving motor 6201, a threaded rod 6203 and a first sliding block 6204. The driving motor 6201 is arranged at the upper end of one side of the fixed frame 61, and a placement groove 6202 is opened on the side of the fixed frame 61 close to the driving motor 6201. The threaded rod 6203 is displaced into the placement groove 6202 on one side of the fixed frame 61. The first sliding block 6204 is arranged on the surface of the threaded rod 6203 and is connected to the connecting frame 63. The driving motor 6201 drives the first sliding block 6204 and the connecting frame 63 to move through the threaded rod 6203, and the first sliding block 6204 slides inside the placement groove 6202 on one side of the fixed frame 61. When using the driving assembly 62, start the driving motor 6201 fixed on one side of the fixing frame 61, so that the threaded rod 6203 fixed to the driving motor 6201 rotates inside the slot 6202 on one side of the fixing frame 61, and then the first sliding block 6204 threadedly connected to the surface of the threaded rod 6203 will slide up and down inside the slot 6202 on one side of the fixing frame 61, and then the first sliding block 6204 drives the connecting frame 63 to move up and down.

[0044] Reference Figure 1-10As shown, this embodiment discloses that the fixing assembly 68 includes a first L-shaped plate 681, a clamping block 682, a second L-shaped plate 684, a first spring 685 and an electric telescopic rod 686. The first L-shaped plate 681 is arranged on the side of the connecting frame 63 away from the first coil spring 66. A clamping slot 683 is provided on the side of the first rotating rod 64 close to the first L-shaped plate 681. The clamping block 682 is inserted into the first L-shaped plate 681 and fixes the first rotating rod 64 through the clamping slot 683 on one side of the first rotating rod 64. The first spring 685 is arranged between the second L-shaped plate 684 and the first L-shaped plate 681 to reset the clamping block 682. The electric telescopic rod 686 is arranged between the second L-shaped plate 684 and the first L-shaped plate 681 to move the clamping block 682. A position sensor 687 is provided on the side of the driving block 618 away from the fixing frame 61. The model of the position sensor 687 can be IKL 015.38 GS4 2319EC. When the fixing assembly 68 is in use, the block 682 passes through the first L-shaped plate 681 fixed to the connecting frame 63 and engages with the slot 683 on the first rotating rod 64 to fix the position of the first rotating rod 64. When the position sensor 687 detects that the control frame 610 is close to the driving block 618 and the first rotating rod 64 needs to be rotated, the electric telescopic rod 686 on the second L-shaped plate 684 fixed to the first L-shaped plate 681 is started, and then the block 682 fixed to the output end of the electric telescopic rod 686 is disengaged from the slot 683. At this time, the first spring 685 is compressed, and then the first rotating rod 64 can rotate on the connecting frame 63. After the first rotating rod 64 is reset, the first spring 685 brings the block 682 back to the original position, so that the block 682 reaches the inside of the slot 683 on the surface of the first rotating rod 64 to fix the position of the first rotating rod 64.

[0045] Reference Figure 1-10As shown, this embodiment discloses a limiting telescopic rod 621 sleeved inside the second spring 617, which limits the shape of the second spring 617. The limiting telescopic rod 621, whose ends are respectively fixed to the lifting plate 67 and the extension block 615 and located inside the second spring 617, limits the shape of the second spring 617, preventing the second spring 617 from bending and affecting its use. Two third discs 622 are provided on the side of the second rotating rod 69 near the control frame 610. The two third discs 622 are located on both sides of the control frame 610 to limit and fix the position of the control frame 610 on the second rotating rod 69. The third discs 622 fixed to the second rotating rod 69 limit the position of the control frame 610, making the position of the control frame 610 and the second rotating rod 69 more secure. A stabilizing groove 623 is defined on the side of the fixed frame 61 away from the drive assembly 62. A stabilizing block 624 is positioned within the stabilizing groove 623 on the side of the fixed frame 61 to limit and stabilize the movement of the connecting frame 63. The stabilizing block 624 is fixed to the connecting frame 63 and slides within the stabilizing groove 623 on the side of the fixed frame 61 to support the side of the connecting frame 63 away from the drive assembly 62, thereby allowing the lifting plate 67 to move up and down more stably.

[0046] Reference Figure 1-10 As shown, this embodiment discloses that the auxiliary component 7 includes a slide groove 71 opened on one side of the lifting plate 67, two second sliding blocks 72 are arranged inside the slide groove 71 on one side of the lifting plate 67, and a plurality of thread grooves 74 are opened on the side of the lifting plate 67 close to the slide groove 71, a second limiting plate 75 is set on one side of the two second sliding blocks 72, a bolt 73 is inserted into one side of the second sliding block 72, and the bolt 73 reaches the inside of the thread groove 74 to fix the second sliding block 72 and the second limiting plate 75. By moving the second limiting plate 75, the second sliding block 72 fixed to the second limiting plate 75 moves inside the slide groove 71, and then the distance between the two second limiting plates 75 is adapted to the size of the material, and then the bolt 73 is rotated to allow the bolt 73 to pass through the second sliding block 72 and be threadedly fixed to the lifting surface thread groove 74, and then the position of the second sliding block 72 and the second limiting plate 75 is fixed. Then the two second limiting plates 75 limit the two sides of the lifting plate 67. By using the auxiliary component 7, the two sides of the lifting plate 67 can be limited to prevent the material from being detached from the two sides of the lifting plate 67 and lifted, thereby increasing the use effect of the lifting plate 67.

[0047] Reference Figure 1-10As shown, this embodiment discloses that the side where the two second limiting plates 75 are close to each other is an arc surface, and the arc surface of the second limiting plates 75 is smooth. By setting the side where the two second limiting plates 75 are close to each other as an arc surface, the friction between the second limiting plates 75 and the material is reduced, so that the material can be better separated from the lifting plate 67 later. A rubber block 76 is provided on the side of the second limiting plate 75 away from the bracket 1, and the rubber block 76 covers the corners of the second limiting plate 75 for protection. By fixing the rubber block 76 at the corner of the second limiting plate 75, it is improved to prevent the operator from colliding with the corner of the second limiting plate 75 and being damaged, thereby improving the safety of the use of the second limiting plate 75.

[0048] Working principle: When loading and unloading materials on a vehicle, the conveyor belt 5 on the bracket 1 will be moved near the vehicle, and the round rod 2 on the bracket 1 will deform the bracket 1 so that one side of the bracket 1 is inside the vehicle, and then the control motor 3 will be started to drive the rotating roller 4 to rotate, and then the conveyor belt 5 on the bracket 1 will be used to transport and load and unload materials. When unloading, the lifting and unloading device 6 will be inside the vehicle, and when loading, the lifting and unloading device 6 will be outside the vehicle to lift the material upward and send the material to the surface of the conveyor belt 5. When using the lifting and unloading device 6, the auxiliary component 7 increases the use effect of some parts of the lifting and unloading device 6. When the material is placed on the lifting plate 67, the second limiting plate 75 is moved to make the second sliding block 72 fixed with the second limiting plate 75 move inside the slide groove 71, and then the distance between the two second limiting plates 75 is adapted to the size of the material, and then the bolt 73 is rotated to make the bolt 73 pass through the second sliding block 72 and the lifting surface thread groove 74 to be threaded and fixed, and then the position of the second sliding block 72 and the second limiting plate 75 is fixed. Then the second limiting plates 75 limit the two sides of the lifting plate 67. After the material is placed on the lifting plate 67, the baffle 611 controls the rotation direction of the control frame 610. The first rotating rod 64 is fixed to the position of the material, and the fixing assembly 68 fixes the position of the first rotating rod 64. Then, after the material is placed on the lifting plate 67, the lifting plate 67 will not be driven to rotate. Then, the driving assembly 62 on the fixing frame 61 fixed to the bracket 1 is started, and then the driving motor 6201 fixed to one side of the fixing frame 61 is started, so that the threaded rod 6203 fixed by the driving motor 6201 rotates inside the slot 6202 on one side of the fixing frame 61. Then, the first sliding block 6204 threadedly connected to the surface of the threaded rod 6203 slides up and down inside the slot 6202 on one side of the fixing frame 61, and then After that, the first sliding block 6204 drives the connecting frame 63 to move, and then the connecting frame 63 moves upward, and then the connecting frame 63 drives the first rotating rod 64 that rotates on the surface to drive the lifting plate 67 fixed to the first rotating rod 64 to move upward, and then after the lifting plate 67 moves to a height higher than the conveyor belt 5, the fixing assembly 68 no longer fixes the first rotating rod 64, and then the driving block 618 fixed to the fixing frame 61 will squeeze the control frame 610 fixed to the second rotating rod 69, so that the control frame 610 is tilted close to the side of the triangular block 616. At this time, the second rotating rod The rod 69 rotates on the connecting frame 63, and the second circular piece 613 fixed to the second rotating rod 69 and the second coil spring 612 fixed between the connecting frame 63 are deformed. Then the control frame 610 squeezes the triangular block 616, so that the extension block 615 fixed on one side of the triangular block 616 slides inside the extension groove 614 on the surface of the lifting plate 67. At this time, the second spring 617 fixed to the extension block 615 and the lifting plate 67 is deformed. At this time, the first limit plates 620 fixed on both sides of the extension block 615 slide inside the limit groove 619 to limit the maximum displacement of the extension block 615.After the extension block 615 reaches the maximum displacement, the control frame 610 causes the lifting plate 67 to tilt away from one side of the bracket 1. At this time, the first rotating rod 64 rotates on the connecting frame 63, and the first disc 65 fixed to the first rotating rod 64 and the first coil spring 66 fixed between the connecting frame 63 will be deformed. Then the material on the lifting plate 67 slides to the extension block 615 on the surface of the lifting plate 67. Then the material reaches the surface of the conveyor belt 5 to complete the lifting and unloading of the material. Then the driving assembly 62 is started to reset the connecting frame 63 to the lower end of the fixed frame 61. Then the driving block 618 is no longer in contact with the control frame 610. Then the second coil spring 612 resets the control frame 610 by resetting the second rotating rod 69. The second spring 617 brings the extension block 615 back to its original position, and the first coil spring 66 drives the first rotating rod 64 to return to its original position, completing the reset of the lifting plate 67. Then, the fixing assembly 68 re-fixes the first rotating rod 64, preventing it from rotating any further. The above operation is then repeated to continuously transport the material to the surface of the conveyor belt 5. By lifting the unloading device 6, the material can be lifted upward and delivered to the surface of the conveyor belt 5, avoiding the need for the operator to constantly lift the material to a higher position. This reduces the operator's labor intensity, allowing the operator to work longer hours during the working hours, thereby improving the efficiency of loading and unloading, and further improving the use effect of the loading and unloading device.
