Description

Technical Field

[0001] This invention relates to the field of conveyor technology, and in particular to a heavy-duty lifting roller conveyor. Background Technology

[0002] Lifting roller conveyors are a type of box material conveying equipment widely used in logistics, warehousing, and manufacturing. Their core structure includes a liftable conveyor frame and multiple rollers mounted on it. During operation, box materials are placed on the rollers, and the rotation of the rollers achieves horizontal transport. The lifting function of the conveyor frame allows the equipment to flexibly adapt to work platforms or conveying links of different heights, enabling smooth transfer of box materials between different heights. In modern production and logistics systems, the efficiency and flexibility of box material conveying are crucial. Lifting roller conveyors, with their liftable characteristics, can effectively connect production lines, warehouse racks, and loading / unloading platforms of different heights, greatly improving the automation and efficiency of box material handling and reducing the labor intensity and time costs of manual handling. Therefore, they have become an indispensable key piece of equipment in many industries.

[0003] Currently, existing lifting roller conveyors still have many shortcomings in practical applications. Regarding load capacity and stability, while current equipment typically has a large load-bearing capacity, the lack of effective securing devices for boxed materials during lifting operations makes them highly susceptible to instability due to changes in acceleration, inertia, and equipment vibration during the lifting process. This can lead to the boxed materials slipping or even tipping over, damaging the materials themselves, affecting product quality, and potentially threatening the safety of nearby operators, causing accidents. Secondly, when transporting boxed materials, the conveyor cannot promptly adjust the position of the materials when the weight distribution is uneven, resulting in uneven pressure distribution across the conveyor. This uneven pressure distribution further exacerbates the instability of the boxed materials during transport, increasing the probability of them falling. Therefore, these shortcomings fail to meet user needs, and further improvements are necessary.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings to provide a heavy-duty lifting roller conveyor, in order to achieve a more practical purpose. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides a heavy-duty lifting roller conveyor, which is achieved by the following specific technical means: A heavy-duty lifting roller conveyor includes a base and a conveyor frame, a protective shell disposed on the conveyor frame, a tensioning component disposed on the protective shell, and a protective mechanism disposed on the tensioning component. The tensioning assembly includes a tensioning base fixedly assembled inside the protective shell. A tensioning frame is fixedly installed on the upper side of the tensioning base. A first servo motor is fixedly assembled on the tensioning frame. A transmission belt is driven to the upper side of the first servo motor via its output end. Two limit buckles are fixedly installed on the transmission belt. A reinforced slide rail is fixedly installed on the upper side of the tensioning frame. Two reinforced slide blocks are slidably installed on the reinforced slide rail. The upper sides of the two limit buckles are fixedly connected to the two reinforced slide blocks respectively. The protective mechanism includes a protective part fixedly mounted on a reinforced slide. A protective plate is slidably installed on one side of the protective part. An elastic reset pad is fixedly connected between one side of the protective plate and the inner wall of the protective part. Protective components are provided inside the protective part and on the left and right sides of the elastic reset pad. An adjustment component is provided in the protective components to adjust the position of the box-type material.

[0006] As a further description of the above technical solution: Through the synergistic effect between the tensioning component and the protective mechanism, the protective plates on both sides automatically center and align the box material, while simultaneously clamping and limiting the box material, ensuring that the box material is in the optimal center position of the conveyor. This setting ensures that the box material remains in the center position of the conveyor throughout the conveying process, effectively avoiding the risk of falling due to deviation and preventing personnel injuries caused by falling box material, thus greatly improving the safety of box material conveying. On the other hand, it facilitates the accurate transfer of the box material to other conveying equipment after lifting and lowering, ensuring that the box material can safely and stably complete the entire lifting and conveying process, reducing conveying failures and damage to box material caused by positional deviations, and improving production efficiency.

[0007] Furthermore, the protective component includes a protective block that is slidably mounted on the protective part, a limiting plate that is fixedly mounted on one side of the protective block, a second inclined block that is fixedly mounted on the side of the limiting plate away from the protective block, and a return spring that is fixedly connected between one side of the limiting plate and the inner wall of the protective part. The protective block has an internal cavity, and a number of openings are provided on one side of the protective block.

[0008] As a further description of the above technical solution: This setting effectively increases the protection range for boxed materials, enabling more effective wrapping and protection of the boxed materials, effectively protecting the lives of surrounding operators, and avoiding personal injury accidents caused by boxed materials falling.

[0009] Furthermore, a first inclined block is fixedly installed on the side of the protective plate facing the elastic reset pad, and the inclined surface of the first inclined block is in contact with the inclined surface of the second inclined block.

[0010] As a further description of the above technical solution: Based on the pressure applied by the protective part, the protective part is driven to squeeze the elastic reset pad, and when the protective plate moves, it will drive the first inclined block to move synchronously. During the movement of the first inclined block, it will push the second inclined block to move to both sides, thereby realizing the driving of the protective component.

[0011] Furthermore, the adjustment assembly includes a drive roller disposed in the opening slot of the protective block, an elastic support pad is fixedly connected between one side of the drive roller and the wall of the opening slot of the protective block, a drive power supply is disposed in the inner cavity of the protective block, and the drive power supply is electrically connected to the drive roller.

[0012] As a further description of the above technical solution: when the boxed material tends to tilt due to uneven weight distribution, the drive roller dynamically balances the position of the boxed material, making the conveying operation more stable, thereby effectively reducing the risk of shaking or overturning of the boxed material due to the shift of the center of gravity. Especially in lifting operations, it can prevent the boxed material from slipping due to changes in acceleration and improve the stability of the conveying process.

[0013] Furthermore, the upper side of the protective shell is provided with a movable groove that matches the protective part.

[0014] As a further description of the above technical solution: This setting facilitates the movement of the protective part on the one hand, and on the other hand, it facilitates the use of the limiting function of the protective part in the moving slot, thereby further improving its applicability.

[0015] Furthermore, the base is provided with a lifting assembly for raising and lowering the conveyor frame. The lifting assembly includes a lifting motor fixedly mounted on the base. The bottom of the lifting motor is fixedly connected to a conveying screw rod via its output end. A lifting block is threadedly connected to the conveying screw rod.

[0016] As a further description of the above technical solution: This setting enables the lifting and lowering of boxed materials.

[0017] Furthermore, the lifting assembly also includes a stabilizing rod fixedly mounted on the base, a stabilizing block slidably mounted on the stabilizing rod, one side of the stabilizing block being fixedly connected to the lifting block, and a conveying block being fixedly mounted on the other side of the stabilizing block, with the side of the conveying block away from the stabilizing block being fixedly connected to the conveying frame.

[0018] As a further description of the above technical solution: the stability of the lifting block movement is effectively ensured by setting up the stabilizing rod and stabilizing block.

[0019] Furthermore, the machine base is provided with a guide assembly, which includes a guide slide rail fixedly mounted on the machine base, a guide slider slidably mounted on the guide slide rail, and one side of the guide slider being fixedly connected to the conveyor frame.

[0020] As a further description of the above technical solution: the setting of guide rails and guide sliders can improve the stability of the conveyor frame and the lifting process of box-type materials, and further enhance its applicability.

[0021] Furthermore, an adjustment assembly is provided on the upper side of the protective shell. The adjustment assembly includes a fixed frame fixedly mounted on the upper side of the protective shell. A second servo motor is fixedly mounted on the fixed frame. An output gear is fixedly connected to the upper side of the second servo motor via its output end. The adjustment assembly also includes a rotating rod, both ends of which are rotatably connected to telescopic rods. The end of the telescopic rod away from the rotating rod is fixedly connected to the protective part. A driven gear that meshes with the driving gear and an adjustment plate for adjusting the box-type material are fixedly installed on the rotating rod.

[0022] As a further description of the above technical solution: This setting can apply a vertically upward reaction force to it, forming a lifting force on the lower side of the box material, thereby effectively reducing the risk of swaying or overturning of the box material due to the shift of the center of gravity. Especially in lifting operations, it can prevent the box material from slipping due to changes in acceleration, improve the stability of the conveying process, and the setting of the telescopic rod ensures that the two protective plates will not affect the adjusting plate when they move relative to each other, further improving its applicability.

[0023] Furthermore, the conveyor frame is provided with a conveying assembly for conveying box-shaped materials. The conveying assembly includes a conveying motor fixedly mounted on the conveyor frame. The output end of the conveying motor is driven by a drive chain. One end of the drive chain is driven by a transmission chain. The transmission chain is equipped with conveying rollers for conveying box-shaped materials.

[0024] As a further description of the above technical solution: by starting the conveyor motor, the output end of the conveyor motor drives the drive chain to move. Through the coordinated action of the drive chain, transmission chain and conveyor roller, the box-shaped material is conveyed to the external conveying equipment by the conveyor roller, thereby realizing the safe conveying of the box-shaped material.

[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. This heavy-duty lifting roller conveyor, through the coordinated action of the tensioning assembly and the protective mechanism, uses the protective plates on both sides to automatically center and align the box-shaped material. Simultaneously, the protective plates clamp and limit the box-shaped material, ensuring it is in the optimal center position of the conveyor. This design ensures that the box-shaped material remains centered throughout the conveyor process, effectively preventing the risk of falling due to deviation and avoiding personnel injuries caused by falling box-shaped material, thus greatly improving the safety of box-shaped material conveying. Furthermore, after lifting, the box-shaped material can be accurately transferred to other conveying equipment, ensuring the safe and stable completion of the entire lifting and conveying process, reducing conveying failures and damage to box-shaped material caused by positional deviations, and improving production efficiency.

[0026] 2. This heavy-duty lifting roller conveyor uses a moving first inclined block to push a second inclined block to move to both sides, which in turn pushes the protective blocks to unfold along both sides of the protective section. After the protective blocks unfold outward, the protection range for box-shaped materials is increased, which can more effectively wrap and protect the box-shaped materials. During the lifting process of the box-shaped materials, even if the box-shaped materials are impacted by external forces or have a tendency to fall due to changes in their own center of gravity, the unfolded protective blocks can also play an effective blocking role, forming an all-round protective barrier. This setting effectively reduces the risk of box-shaped materials falling, further protects the life safety of operators, reduces equipment damage and production interruptions caused by box-shaped materials falling, and improves the reliability and stability of the entire conveying system.

[0027] 3. This heavy-duty lifting roller conveyor, when the boxed material tends to tilt due to uneven weight distribution, the drive power supply powers the drive rollers to operate. The drive rollers apply a counterforce through friction with the outer wall of the boxed material, pushing the material towards a stable center of gravity, thus achieving dynamic balance. This design makes the conveying of boxed material smoother, effectively reducing the risk of swaying or tipping caused by center of gravity shift. Especially during lifting operations, it can prevent the boxed material from slipping due to changes in acceleration, significantly improving the stability of the conveying process and ensuring the safe conveying of boxed material under complex working conditions. As the rotating rod continues to rotate, the adjusting plate deflects around the fulcrum, and its rising side gradually rises. When the rising side of the adjusting plate contacts the lower side of the box material, it applies a vertically upward reaction force to it, forming a lifting force on the lower side of the box material. Combined with the horizontal adjustment of the box material by the drive roller, a dual correction mechanism of vertical lifting and horizontal pushing and pulling is formed, which effectively copes with multi-dimensional deviations during the conveying process. This setting effectively reduces the risk of swaying or overturning of the box material due to the shift of the center of gravity. Especially in lifting operations, it can prevent the box material from slipping due to changes in acceleration, thus improving the stability of the conveying process. Attached Figure Description

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1 to 12 A heavy-duty lifting roller conveyor includes a base 10 and a conveyor frame 11, a protective shell 12 mounted on the conveyor frame 11, a tensioning assembly 50 mounted on the protective shell 12, and a protective mechanism 60 mounted on the tensioning assembly 50. The tensioning assembly 50 includes a tensioning base 51 fixedly mounted inside the protective shell 12, a tensioning frame 52 fixedly mounted on the upper side of the tensioning base 51, a first servo motor 53 fixedly mounted on the tensioning frame 52, a transmission belt 54 driven through the output end of the first servo motor 53, two limit buckles 57 fixedly mounted on the transmission belt 54, and the upper side of the tensioning frame 52... A reinforced slide rail 55 is fixedly installed, and two reinforced slide blocks 56 are slidably installed on the reinforced slide rail 55. The upper sides of two limit buckles 57 are fixedly connected to the two reinforced slide blocks 56 respectively. The protective mechanism 60 includes a protective part 61 fixedly assembled on the reinforced slide block 56. A protective plate 62 is slidably installed on one side of the protective part 61. One side of the protective plate 62 extends into the interior of the protective part 61 and is fixedly connected to the inner wall of the protective part 61 with an elastic reset pad 63. A protective component 64 is provided inside the protective part 61 and on the left and right sides of the elastic reset pad 63. An adjustment component 65 for adjusting the position of the box-type material is provided in the protective component 64.

[0033] Through the coordinated action of the tensioning component 50 and the protective mechanism 60, the protective plates 62 on both sides automatically center and align the box material, while simultaneously clamping and limiting the box material to ensure it is in the optimal center position of the conveyor. This design ensures that the box material remains centered on the conveyor throughout the conveying process, effectively preventing the risk of falling due to deviation and avoiding personnel injuries caused by falling box material, thus greatly improving the safety of box material conveying. On the other hand, it facilitates the accurate transfer of the box material to other conveying equipment after lifting and lowering, ensuring that the box material can safely and stably complete the entire lifting and conveying process, reducing conveying failures and damage to box material caused by positional deviations, and improving production efficiency.

[0034] Please see Figures 1 to 2 , Figure 5 The base 10 is equipped with a lifting assembly 20 for lifting the conveyor frame 11. The lifting assembly 20 includes a lifting motor 21 fixedly mounted on the base 10. The bottom of the lifting motor 21 is fixedly connected to a conveying screw 22 via its output end. A lifting block 23 is threadedly connected to the conveying screw 22. By starting the lifting motor 21, the output end of the lifting motor 21 drives the conveying screw 22 to rotate. As the conveying screw 22 rotates, the lifting block 23 will perform lifting operations on the conveying screw 22. During the movement of the lifting block 23, it simultaneously drives the stabilizing block 25 and the conveying block 26 to move synchronously. The conveying block 26 then drives the conveyor frame 11 and the box-shaped material to lift, thereby realizing the lifting operation of the box-shaped material.

[0035] Please see Figures 1 to 2 , Figure 5 The lifting assembly 20 also includes a stabilizing rod 24 fixedly mounted on the base 10. A stabilizing block 25 is slidably mounted on the stabilizing rod 24. One side of the stabilizing block 25 is fixedly connected to the lifting block 23, and a conveying block 26 is fixedly mounted on the other side of the stabilizing block 25. The side of the conveying block 26 away from the stabilizing block 25 is fixedly connected to the conveying frame 11. The stabilizing rod 24 and the stabilizing block 25 effectively ensure the stability of the movement of the lifting block 23.

[0036] Please see Figures 1 to 2 The base 10 is provided with a guide assembly 30, which includes a guide slide rail 31 fixedly mounted on the base 10, and a guide slider 32 slidably mounted on the guide slide rail 31. One side of the guide slider 32 is fixedly connected to the conveyor frame 11. The arrangement of the guide slide rail 31 and the guide slider 32 can improve the stability of the conveyor frame 11 and the box material lifting process.

[0037] Please see Figures 10 to 12The protective component 64 includes a protective block 641 slidably mounted on the protective part 61. A limit plate 642 is fixedly installed on one side of the protective block 641, and a second inclined block 643 is fixedly installed on the side of the limit plate 642 away from the protective block 641. A return spring 644 is fixedly connected between one side of the limit plate 642 and the inner wall of the protective part 61. The protective block 641 has an inner cavity and several opening slots on one side. As the protective block 641 unfolds along both sides of the protective part 61, the protective block 641 increases the protection range for the boxed material. It can more effectively wrap and protect the boxed material. Even if the boxed material is impacted by external force or tends to fall due to changes in its center of gravity during lifting, the unfolded protective block 641 can still act as a stop, greatly reducing the possibility of the boxed material falling. This effectively protects the lives of surrounding operators and avoids personal injury accidents caused by falling boxed materials.

[0038] Please see Figures 10 to 12 A first inclined block 621 is fixedly installed on the side of the protective plate 62 facing the elastic reset pad 63. The inclined surface of the first inclined block 621 is in contact with the inclined surface of the second inclined block 643. Based on the pressure applied by the protective part 61, the protective plate 62 will continuously squeeze the box material. During the squeezing process, the protective plate 62 will squeeze the elastic reset pad 63 as the protective part 61 moves. When the protective plate 62 moves, it will drive the first inclined block 621 to move synchronously. During the movement of the first inclined block 621, it will push the second inclined block 643 to move to both sides, thereby driving the protective component 64.

[0039] Please see Figures 10 to 12 The adjustment component 65 includes a drive roller 651 disposed in the opening slot of the protective block 641. An elastic support pad 652 is fixedly connected between one side of the drive roller 651 and the wall of the opening slot of the protective block 641. A drive power supply 653 is disposed in the inner cavity of the protective block 641. The drive power supply 653 is electrically connected to the drive roller 651. When the box material tends to tilt due to uneven weight distribution, the drive power supply 653 supplies power to the drive roller 651, causing the drive roller 651 to start running. The drive roller 651 applies a counterforce through friction with the outer wall of the box material, pushing the box material to move in the direction of stable center of gravity, thereby forming dynamic balance. By dynamically balancing the position of the box material, the drive roller 651 makes the conveying operation more stable, thereby effectively reducing the risk of shaking or overturning of the box material due to the shift of the center of gravity. Especially in lifting operations, it can prevent the box material from slipping due to changes in acceleration, and improve the stability of the conveying process.

[0040] Please see Figure 4 , Figure 6An adjustment assembly 70 is provided on the upper side of the protective shell 12. The adjustment assembly 70 includes a fixed frame 71 fixedly mounted on the upper side of the protective shell 12, a second servo motor 72 fixedly mounted on the fixed frame 71, and a drive gear 73 fixedly connected to the upper side of the second servo motor 72 via its output end. The adjustment assembly 70 also includes a rotating rod 74, with telescopic rods 77 rotatably connected to both ends of the rotating rod 74. The end of the telescopic rod 77 away from the rotating rod 74 is fixedly connected to the protective part 61. A driven gear 75 meshing with the drive gear 73 and an adjustment plate 76 for adjusting the box-type material are fixedly mounted on the rotating rod 74. By starting the second servo motor 72, the output end of the second servo motor 72 drives the drive gear 73 to rotate, and the meshing transmission between the drive gear 73 and the driven gear 75 drives the rotating rod 74 to move the adjustment plate 76. The initial surface of the adjustment plate 76... The initial position is slightly lower than the conveying roller 44. The rotating rod 74 drives the adjusting plate 76 to rotate. When the rotating rod 74 is driven by the driven gear 75, the rotational motion is converted into the planar displacement and angular change of the adjusting plate 76. With the continuous rotation of the rotating rod 74, the adjusting plate 76 deflects around the fulcrum, and its rising side gradually rises. When the rising side of the adjusting plate 76 contacts the lower side of the box material, it applies a vertically upward reaction force to it, forming a lifting force on the lower side of the box material. Combined with the horizontal adjustment of the box material by the drive roller 651, a dual correction mechanism of vertical lifting and horizontal pushing and pulling is formed, which effectively copes with multi-dimensional deviations during the conveying process. This setting effectively reduces the risk of swaying or overturning of the box material due to the shift of the center of gravity. Especially in the lifting operation, it can avoid the box material from slipping due to changes in acceleration and improve the stability of the conveying process.

[0041] Please see Figure 7 The upper side of the protective shell 12 is provided with a movable groove 121 that matches the protective part 61. By providing a movable groove 121 on the upper side of the protective shell 12, it is convenient for the protective part 61 to move, and it is also convenient to use the limiting function of the protective part 61 by utilizing the movable groove 121.

[0042] Please see Figure 1 , Figures 3 to 4 The conveyor frame 11 is equipped with a conveying assembly 40 for conveying boxed materials. The conveying assembly 40 includes a conveying motor 41 fixedly mounted on the conveyor frame 11. The output end of the conveying motor 41 is driven by a drive chain 42. One end of the drive chain 42 is driven by a transmission chain 43. The transmission chain 43 is equipped with a conveying roller 44 for conveying boxed materials. By starting the conveying motor 41, the output end of the conveying motor 41 drives the drive chain 42 to move. Through the coordinated action of the drive chain 42, the transmission chain 43 and the conveying roller 44, the conveying roller 44 is used to convey the boxed materials to external conveying equipment, thereby realizing the safe conveying of boxed materials.

[0043] Working principle: First, the boxed material is smoothly conveyed to the conveying roller 44 on the conveyor frame 11 of this device through external conveying equipment. Then, the first servo motor 53 is started and the output end of the first servo motor 53 starts to run, driving the transmission belt 54 to move. Since the transmission belt 54 is equipped with two limit buckles 57, and these two limit buckles 57 are located on both sides of the transmission belt 54, the two limit buckles 57 will move relative to each other under the drive of the transmission belt 54. While the limit buckles 57 are moving, they will drive the reinforcing slide 56 to slide synchronously on the reinforcing slide rail 55. During the movement of the reinforcing slide 56, it will also drive the protective part 61 connected to it to move synchronously, thereby driving the protective plate 62 on the protective part 61 to come into contact with the boxed material. After the protective plates 62 come into contact with the box material, the protective plates 62 on both sides will apply force to the box material to achieve automatic centering and alignment, so that the box material is in the optimal center position of the conveyor. At the same time, the protective plates 62 also clamp and limit the box material. When the conveyor is lifting and lowering, acceleration changes and vibrations will occur. At this time, the clamping and limiting function of the protective plates 62 can firmly fix the box material, preventing the box material from sliding, shifting or falling due to inertia. This setting can keep the box material in the center position of the conveyor at all times during the conveying process, effectively avoiding the risk of falling due to deviation, effectively protecting the lives of surrounding operators, and avoiding personal injury accidents caused by falling box material. On the other hand, it can make it easy to accurately transport the box material to other conveying equipment after lifting and lowering, ensuring that the box material can safely and stably complete the entire lifting and conveying process. As the protective unit 61 drives the protective plate 62 to center and limit the box material, the protective plate 62 will continuously squeeze the box material based on the pressure applied by the protective unit 61. During the squeezing process, the protective plate 62 will squeeze the elastic reset pad 63 as the protective unit 61 moves. When the protective plate 62 moves, it will drive the first inclined block 621 to move synchronously. During the movement of the first inclined block 621, it will push the second inclined block 643 to move to both sides, thereby pushing the protective block 641 to unfold along both sides of the protective unit 61. After the protective block 641 unfolds outward, it increases the protection range of the box material, which can more effectively wrap and protect the box material. Even if the box material is impacted by external force or has a tendency to fall due to its own center of gravity change during the lifting process, the unfolded protective block 641 can also play a blocking role, greatly reducing the possibility of the box material falling, effectively protecting the life safety of the surrounding operators, and avoiding personnel injury accidents caused by the box material falling. When the protective blocks 641 on both sides of the protective section 61 unfold outward, the drive roller 651 in the adjusting assembly 65 loses the pressure from the inner wall of the protective section 61. At this time, based on the elastic force of the elastic support pad 652, the drive roller 651 will be pushed outward, so that the drive roller 651 comes into contact with the outer wall of the box material. When the box material tends to tilt due to uneven weight distribution, the drive power supply 653 will supply power to the drive roller 651. The drive roller 651 uses a drive wheel assembly that can run as soon as it is powered on. With the power supply 653, the drive roller 651 starts to run. The drive roller 651 applies a reverse force through the friction with the outer wall of the box material, pushing the box material to move in the direction of stable center of gravity, thereby forming dynamic balance. The drive roller 651 makes the conveying operation more stable by dynamically balancing the position of the box material. In addition, by starting the second servo motor 72, the output end of the second servo motor 72 drives the drive gear 73 to rotate, and the drive gear 73 and the driven gear 73 interact with the driven gear 751 to make the conveying operation more stable. The meshing transmission between the driving gears 75 drives the rotating rod 74 to move the adjusting plate 76. The initial position of the upper surface of the adjusting plate 76 is slightly lower than that of the conveying roller 44. The rotating rod 74 drives the adjusting plate 76 to rotate. When the rotating rod 74 is driven by the driven gear 75, the rotational motion is converted into the planar displacement and angular change of the adjusting plate 76. With the continuous rotation of the rotating rod 74, the adjusting plate 76 deflects around the fulcrum, and its rising side gradually rises. When the rising side of the adjusting plate 76 contacts the lower side of the box material, it applies a vertical upward reaction force to it, forming a lifting force on the lower side of the box material. Combined with the horizontal adjustment of the box material by the driving roller 651, a dual correction mechanism of vertical lifting and horizontal pushing and pulling is formed, which effectively copes with the multi-dimensional deviation during the conveying process. This setting effectively reduces the risk of swaying or overturning of the box material due to the shift of the center of gravity. Especially in the lifting operation, it can avoid the box material from slipping due to the change of acceleration and improve the stability of the conveying process. Once the boxed material is securely fixed, the lifting motor 21 is started. The output end of the lifting motor 21 drives the conveying screw 22 to rotate. As the conveying screw 22 rotates, the lifting block 23 will lift and lower on the conveying screw 22. During the movement of the lifting block 23, the stabilizing block 25 and the conveying block 26 will move synchronously. The conveying block 26 will then drive the conveying frame 11 and the boxed material to lift and lower, thereby realizing the lifting and lowering operation of the boxed material. When the box material is raised to the designated height, the lifting motor 21 stops running. At the same time, the first servo motor 53 is started to run in reverse, driving the transmission belt 54 to move in the opposite direction. The reverse movement of the transmission belt 54 will cause the two reinforced slides 56 to separate the two protective components 64 from each other, releasing the restriction on the box material. After the protective plate 62 in the protective component 64 separates from the box material, the protective plate 62 loses its pressing force. Based on the elastic force of the elastic reset pad 63, it will push the protective plate 62 to automatically reset. At the same time, under the elastic force of the reset spring 644, the limit plate 642 will drive the protective block 641 to automatically retract, realizing the reset of the protective block 641. At this time, the conveyor motor 41 is started again. The output end of the conveyor motor 41 drives the drive chain 42 to move. Through the coordinated action of the drive chain 42, the transmission chain 43 and the conveyor roller 44, the conveyor roller 44 is used to transport the box material to the external conveying equipment, thereby realizing the safe transport of the box material.
