Description

Technical Field

[0001] This utility model belongs to the technical field of drum dryers, and specifically relates to a material box turning device and turning assembly. Background Technology

[0002] In many fields such as industrial production, logistics warehousing, and food processing, materials are usually stored in dedicated material boxes or containers and transferred between different workstations via conveyor equipment. However, in some environments where fixed conveyor belts cannot be installed due to space constraints, process layout, or cost considerations, the transfer and unloading of material boxes are highly dependent on manual operation.

[0003] Currently, when material bins loaded with heavy materials need to be tilted to pour the contents into automatic feeders, mixing equipment, or designated areas, the common method is for multiple operators to work together manually. They need to lift, push, and tilt the heavy bins, a process that is not only extremely labor-intensive and time-consuming, resulting in low overall efficiency, but also poses significant safety hazards. Specifically, during manual tilting, uneven force, slipping, or loss of balance can easily cause the bins to tip over, spill materials, and even cause injuries such as muscle strains and crush injuries to the workers.

[0004] Therefore, the current technology lacks a dedicated device that can safely and efficiently replace manual labor in the tilting of heavy material boxes, which has become a bottleneck restricting the automation level and production safety improvement of related processes. It is necessary to design a dedicated tilting device with a simple structure and convenient operation to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a material box tilting device and tilting assembly. A first linear drive component pushes the tilting bracket to rotate, thereby tilting the material box and discharging the material inside. This overcomes the shortcomings of existing methods where material boxes are manually tilted, which not only leads to low overall work efficiency but also poses significant safety hazards. The specific technical solution is as follows: A material box tilting device includes a fixed bracket, a tilting bracket, a front limiting frame, a side limiting frame, a first linear drive component, and a hinge. The fixed bracket is fixedly installed on the ground. One side of the tilting bracket is rotatably connected to the fixed bracket via a hinge. The front limiting frame is vertically installed on the top of the tilting bracket near the hinge, and a discharge port is provided on the front limiting frame. The side limiting frames are symmetrically and vertically installed on both sides of the top of the tilting bracket. The side limiting frames are perpendicular to and connected to the front limiting frame. One end of the first linear drive component is rotatably connected to the side limiting frame, and the other end is rotatably connected to the fixed bracket.

[0006] Preferably, the height of the front limiting frame and the side limiting frame is greater than or equal to two-thirds of the height of the material box.

[0007] Preferably, it further includes a locking unit, which includes a second linear drive, a rotating shaft, a connecting rod, and a locking frame. The rotating shaft is rotatably mounted on the side of the flip bracket away from the hinge. One end of the connecting rod is fixedly connected to the rotating shaft. One end of the second linear drive is rotatably connected to the bottom of the flip bracket. The other end of the second linear drive is rotatably connected to the other end of the connecting rod. The locking frame is fixedly mounted on the rotating shaft.

[0008] Preferably, the locking frame includes a first locking rod, a second locking rod, and a reinforcing rod. One end of the first locking rod is connected to one end of the second locking rod and they are perpendicular to each other. One end of the second locking rod is fixedly connected to the rotating shaft. The second locking rods are respectively installed at both ends of the rotating shaft. Both ends of the reinforcing rod are respectively connected to the first locking rod. After the second linear drive pushes the connecting rod to rotate to the designated position, the first locking rod locks the material box.

[0009] Preferably, a guide plate is installed at one top end of the front limiting frame and the side limiting frame, and one bottom end of the guide plate is connected to the front limiting frame and the side limiting frame. Multiple guide plates are combined to form a horn shape, and the opening at the smaller end of the horn shape is connected to the front limiting frame and the side limiting frame.

[0010] A flipping assembly includes the aforementioned material box flipping device, and further includes a box body, a base plate, and steel wire ropes. The box body is mounted on top of the base plate, a discharge hole is provided on one side of the box body, and a feed inlet is provided on the top of the box body. The two ends of the steel wire ropes are respectively connected to the two sides of the base plate, and multiple steel wire ropes are arrayed on the base plate.

[0013] Preferably, a push-pull handle is installed on the side of the base plate away from the discharge hole.

[0014] Compared with existing technologies, this utility model has the following beneficial effects: 1. This utility model uses a first linear drive component to push the tilting bracket to rotate, thereby tilting the material box and discharging the material inside the material box. This overcomes the shortcomings of the existing method of manually tilting the material box, which not only leads to low overall work efficiency but also poses significant safety hazards.

[0015] 2. This utility model uses a second linear drive to drive the connecting rod to rotate, which in turn drives the rotating shaft to rotate, thereby driving the locking frame to rotate. When the second linear drive extends to the designated position, the locking frame locks the bottom plate of the material box to prevent the material box from tipping over during the flipping process, ensuring the stable operation of the material box flipping device and avoiding production accidents.

[0016] 3. This utility model ensures that the center of gravity of the material box is always located in the vertical direction of the front limit frame and the flipping support by setting the height of the front limit frame and the side limit frame to be greater than or equal to two-thirds of the height of the material box. This further prevents the material box from tipping over during the flipping process, reduces the load on the locking frame, and ensures the stable operation of the material box flipping device.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Next, refer to Figures 1 to 4 The working principle of this embodiment will be described in detail so that those skilled in the art can better understand this utility model: On one hand, this utility model provides a material box flipping device, including a fixed bracket 2, a flipping bracket 3, a front limiting frame 5, a side limiting frame 6, a first linear drive component 7, and a hinge 8. The fixed bracket 2 is fixedly installed on the ground, and one side of the flipping bracket 3 is rotatably connected to the fixed bracket 2 via the hinge 8. The front limiting frame 5 is vertically welded to the top of the flipping bracket 3 near the hinge 8. The front limiting frame 5 has a discharge port 51, the width of which is greater than or equal to the width of the discharge hole 102 plus the allowance between the box body 1 and the side limiting frames 6, thereby preventing the front limiting frame 5 from restricting the material from being discharged from the discharge port 51. The side limiting frames 6 are symmetrically and vertically welded to both sides of the top of the flipping bracket 3. The side limiting frames 6 are perpendicular to and connected to the front limiting frame 5, thereby forming mutual support and increasing the overall strength. At the same time, the side limiting frames 6 are used to position the relative position of the box body 1 and the material inlet, ensuring that the material can accurately fall into the material inlet after leaving the material box. One end of the first linear drive component 7 is rotatably connected to the side limiting frame 6, and the other end is rotatably connected to the fixed bracket 2. The aforementioned first linear drive component 7 can be a hydraulic cylinder, a pneumatic cylinder, or an electric push rod, etc. If a pneumatic cylinder is used, it needs to be used in conjunction with a pneumatically controlled check valve.

[0025] When the operator activates the first linear drive 7 via the terminal, the moving part of the first linear drive 7 extends, pushing the tilting bracket 3 to rotate around the hinge 8, thereby causing the material box to rotate synchronously and tilt. During the rotation of the material box, the front limit plate will limit the material box to prevent it from sliding down or tipping over. Depending on the specifications of the material box, there are two types: one with automatically opening discharge hole 102 and one that requires manual opening by the operator. The material box with automatically opening discharge hole 102 will gradually discharge the material inside the material box as it rotates and tilts, and will remain stationary at the designated position until all the material inside the material box slides out of the material box under its own weight. The material box that requires manual opening by the operator needs to have the discharge hole 102 of the material box opened manually by the operator before activating the first linear drive 7 via the control terminal. The subsequent material discharge method is the same as that of the material box with automatically opening discharge hole 102, which will not be described in detail here. After the material is completely discharged, the operator can control the first linear drive 7 via the terminal to retract, causing the tilting bracket 3 and the material box to rotate in the opposite direction to the initial position. By adopting the above-mentioned automatic flipping material box method, labor costs can be reduced and work efficiency can be improved. For some materials that have certain requirements on the contact time with air, the contact time between the material and the air can also be reduced, thus ensuring the quality of product production.

[0026] The height of the front limit frame 5 and the side limit frame 6 is greater than or equal to two-thirds of the height of the material box, which can ensure that the center of gravity of the material box is always located in the vertical direction of the front limit frame 5 and the flipping bracket 3, further preventing the material box from tipping over during the flipping process, reducing the load on the locking frame 12, and ensuring the stable operation of the material box flipping device.

[0027] The locking unit includes a second linear drive component 9, a rotating shaft 10, a connecting rod 11, and a locking frame 12. The rotating shaft 10 is rotatably mounted on the side of the tilting bracket 3 away from the hinge 8 via bearings. One end of the connecting rod 11 is welded to the rotating shaft 10. One end of the second linear drive component 9 is rotatably connected to the bottom of the tilting bracket 3 via the hinge 8, and the other end of the second linear drive component 9 is rotatably connected to the other end of the connecting rod 11 via the hinge 8. The locking frame 12 is fixedly mounted on the rotating shaft 10. Before the material box rotates, the operator needs to control the extension movement of the moving end of the second linear drive component 9 via a terminal. The second linear drive component 9 pushes the rotating shaft 10 to rotate via the connecting rod 11. The rotation of the rotating shaft 10 drives the locking frame 12 to rotate. When the second linear drive component 9 extends to the designated position, the locking frame 12 locks the bottom plate 14 of the material box, preventing the material box from tipping over during the tilting process, ensuring the stable operation of the material box tilting device, and avoiding production accidents. The aforementioned second linear drive component 9 can be a hydraulic cylinder, a pneumatic cylinder, or an electric push rod, etc. If a cylinder is used, it needs to be used in conjunction with a pneumatically controlled check valve.

[0028] The locking frame 12 includes a first locking rod 121, a second locking rod 122, and a reinforcing rod 123. One end of the first locking rod 121 and one end of the second locking rod 122 are integrally formed and perpendicular to each other. One end of the second locking rod 122 is welded to the rotating shaft 10. The second locking rod 122 is installed at both ends of the rotating shaft 10. Both ends of the reinforcing rod 123 are bolted to the first locking rod 121. The reinforcing rod 123 is used to increase the strength of the first locking rod 121 and the second locking rod 122 and reduce the probability of deformation. After the second linear drive 9 pushes the connecting rod 11 to rotate to the designated position, the first locking rod 121 locks the bottom plate 14 of the material box, so that the bottom plate 14 is always in contact with the flipping bracket 3 to ensure stability.

[0029] Guide plates are bolted to one end of the top of the front limiting frame 5 and the side limiting frame 6. The bottom end of the guide plate is connected to the front limiting frame 5 and the side limiting frame 6. Multiple guide plates are combined to form a horn shape, with the opening at the smaller end of the horn shape connected to the front limiting frame 5 and the side limiting frame 6. The guide plates are used to increase the entry distance between the side limiting frames 6, making it easier for operators to load material carts into the material box tipping device using lifting equipment, thus improving work efficiency.

[0030] On the other hand, this utility model also provides a flipping assembly, which includes the aforementioned material box flipping device, as well as a box body 1, a base plate 14, and steel wire ropes 13. The box body 1 is welded to the top of the base plate 14. A discharge hole 102 is provided on one side of the box body 1, and a feed inlet 101 is provided on the top of the box body 1. The two ends of the steel wire ropes 13 are respectively connected to the two sides of the base plate 14, and multiple steel wire ropes 13 are arrayed on the base plate 14. The operator needs to use a hoist and the steel wire ropes 13 to transport the material box to a higher position and place it into the material box flipping device. Depending on the specifications and models of the material box, there are two types: one with a normally open discharge hole 102 and the other with a switching mechanism. For materials with a normally open discharge hole 102, when loading materials into the material box, the materials generally need to be placed in a package first, and then the package is placed into the material box to prevent the materials from sliding out of the material box on their own. When it is necessary to discharge materials from the material box, the operator needs to open the package.

[0031] An inclined plate 15 is installed on the bottom inner side of the box 1. The inclined plate 15 is connected to the inner wall of the box 1. The area where the inclined plate 15 connects to the discharge hole 102 is the lowest point. The inclined plate 15 can increase the downward separation of materials when they slide, thereby ensuring that the materials can slide out of the material box better under their own weight, avoiding material residue that would require manual handling. At the same time, it can reduce the angle at which the material box needs to be tilted, preventing the material box from tipping over and ensuring the installation and operation of the device. A push-pull handle 4 is welded and installed on the side of the bottom plate 14 away from the discharge hole 102, which allows the operator to make auxiliary fine adjustments while ensuring safety when moving the material box.

[0032] The box 1 is square, allowing for maximum material loading. Multiple baffles 16 are vertically installed inside the box 1, forming an octagon with the inner wall of the box 1. The edges of the baffles 16 on both sides of the discharge hole 102 are flush with the edge of the discharge hole 102. An inclined plate 15 connects to the inner wall of the box 1 and the baffles 16. The baffles 16 on both sides of the discharge hole 102 guide the material to the discharge hole 102, preventing material accumulation inside the box 1.

[0033] In another embodiment, if the cylindrical box 1 is used, the baffle 16 is not needed to guide the materials. However, compared with the square material box, the cylindrical material box has a lower space utilization rate when parked and stored, and it is not easy to position it when placed on the material box flipping device. The choice can be made according to the actual situation.

[0034] In summary, the operating procedure of the material box tilting device is as follows: The operator moves the material box onto the tilting bracket 3 using a lifting device, positioning it between the side limiting frames 6, with the side of the material box having the discharge hole 102 aligned with the front limiting frame 5. Then, the operator can activate the second linear drive 9 via the terminal. The second linear drive 9 pushes the rotating shaft 10 to rotate via the connecting rod 11. The rotation of the rotating shaft 10 drives the locking frame 12 to rotate. When the second linear drive 9 extends to the designated position, the locking frame 12 locks the bottom plate 14 of the material box, preventing the material box from tipping over during the tilting process. Afterwards, the operator activates the first linear drive 7 via the terminal, pushing the tilting bracket 3 to rotate around the hinge 8, thereby causing the material box to rotate synchronously and tilt. During the rotation of the material box, the front limiting plate will limit the material box, preventing it from sliding down or tipping over. As the material box gradually rotates and tilts, the material inside will gradually be discharged, and it will remain stationary at the designated position until all the material inside the material box slides out of the material box under its own weight. Finally, after all the material in the material box has been discharged, the operator can use the terminal to control the first linear drive 7 and the second linear drive 9 to return to their initial state, and then use the lifting device to replace the material box with a new one.
