Description

Technical Field

[0001] This application relates to the technical field of flipping devices, and particularly to a flipping mechanism for wood pallet production. Background Art

[0002] A wood pallet is a pallet made of natural wood. It is the most widely used pallet at present. A pallet is a horizontal platform device used for containerizing, stacking, handling, and transporting goods and products placed as a unit load, facilitating the loading, unloading, and handling of unit materials and small quantities of materials.

[0003] For the related technology above, reference can be made to the patent with the publication number CN219585233U, which discloses a wood pallet flipping mechanism, including a base, an electric motor, a bidirectional screw mechanism, a fixed block, two connecting blocks, two guiding mechanisms, two connecting rods, and two support plates. The electric motor is fixedly connected to one side of the base, the bidirectional screw mechanism is rotatably connected in the base, the fixed block is fixedly connected in the base, the lower ends of the two connecting blocks are respectively arranged on the inner bottom of the base through the two guiding mechanisms, the lower ends of the two connecting rods are respectively hinged to the upper ends of the two connecting blocks, the opposite ends of the two support plates are respectively hinged to both sides of the upper end of the fixed block, and the upper ends of the two connecting rods are respectively hinged to the lower surfaces of the two support plates.

[0004] In view of the above related technology, on the production line, when a wood pallet is flipped by an automatic flipping mechanism of the wood pallet, if the conveying interval time between wood pallets is short, the next wood pallet is likely to collide with the flipping mechanism. If the conveying interval time between wood pallets is long, the flipping time of the wood pallet is prolonged, reducing the production efficiency. Summary of the Invention

[0005] In order to avoid the next wood pallet from colliding with the flipping mechanism during the flipping process of the wood pallet, and at the same time, after one flipping is completed, the next wood pallet can be conveyed in time to improve the efficiency, this application provides a flipping mechanism for wood pallet production.

[0006] This application provides a flipping mechanism for wood pallet production, adopting the following technical solution:

[0007] A turning mechanism for wooden pallet production, comprising a first conveying component, a second conveying component and a support frame. The support frame is located between the first conveying component and the second conveying component. A driving plate is rotatably connected to the support frame, and a driving motor is installed on the support frame. The output shaft of the driving motor is coaxially and fixedly connected to the driving plate. Turning frames are arranged on both sides of the driving plate. The first conveying component includes a first conveying frame and a number of first conveying rollers. A support plate located below the first conveying rollers is fixedly connected to the first conveying frame. A wheel groove is formed in the support plate, and a cam is rotatably connected in the wheel groove. The cross-section of the cam is oval. The cam is rotatably connected to the support plate through a connecting shaft. A rod groove is formed in the support plate in the vertical direction above. A limiting rod is arranged in the rod groove. The limiting rod is movably connected to the support plate. When the end of the limiting rod abuts against the convex part of the cam, the end of the limiting rod away from the cam is located above the first conveying roller.

[0008] By adopting the above technical solution, the wooden pallet is conveyed to the turning frame through the first conveying component. At this time, the shorter diameter side of the cam abuts against the limiting rod, and the end of the limiting rod is located below the top of the first conveying roller. Start the driving motor to rotate the driving plate. After the driving plate rotates 180 degrees, the turning frame with the wooden pallet moves to one side of the second conveying component. The turned wooden pallet is conveyed through the second conveying component. During the rotation of the driving plate, the connecting shaft is rotated synchronously with the driving plate, and the cam rotates, causing the limiting rod to move upward. The upper end of the limiting rod is located above the first conveying roller to block the wooden pallet conveyed on the first conveying component. When the driving plate rotates 90 degrees, the limiting rod is at the highest height. After the driving plate rotates 180 degrees, the limiting rod completes a lifting movement and moves to below the top of the first conveying roller, enabling the next wooden pallet to be conveyed along the first conveying component.

[0009] Optionally, the output shaft of the driving motor and the connecting shaft are connected by a connecting belt.

[0010] By adopting the above technical solution, when the driving motor rotates the driving plate, the connecting shaft is rotated by the connecting belt, so that the driving plate and the connecting shaft rotate synchronously.

[0011] Optionally, spring grooves are formed in the support plate on both sides of the rod groove. Spring plates located in the spring grooves are arranged on the limiting rod. Elastic springs located above the spring plates are arranged in the spring grooves. When the elastic springs are in a natural state, the spring plates are located at the bottom of the spring grooves.

[0012] By adopting the above technical solution, when the cam rotates, as the diameter part of the cam in contact with the limit rod gradually increases, the limit rod gradually moves upward, the elastic spring is compressed, and the compressed elastic spring exerts a downward elastic force on the spring plate. When the cam rotates and the diameter part of the cam in contact with the limit rod gradually decreases, the compressed elastic spring releases the elastic force, pushing the elastic plate downward, causing the limit rod to move downward, so that the end of the limit rod always abuts against the side wall of the cam, improving the stability.

[0013] Optionally, the flipping frame includes a limit plate and a flipping plate. The flipping plate is fixedly installed on the driving plate. The limit plate on the side close to the first conveying assembly is located above the flipping plate, and the limit plate on the side close to the second conveying assembly is located below the flipping plate.

[0014] By adopting the above technical solution, the wooden pallet passing through the first conveying assembly is supported by the flipping frame. The flipping plate is located below the wooden pallet, and the limit plate is located above the wooden pallet. When the driving plate rotates, the flipping plate and the limit plate jointly clamp and flip the wooden pallet.

[0015] Optionally, moving rods are provided on one side of each of the two limit plates close to each other. The moving rods are inserted into the driving plate and are slidably connected to the driving plate. Moving racks are provided on one side of the two moving rods close to each other. A rotating gear is rotatably connected in the driving plate, and the rotating gear meshes with the two moving racks.

[0016] By adopting the above technical solution, the rotating gear in the driving plate is rotated, and the two moving rods are driven to move through the two moving racks, so that the two limit plates approach or move away from each other, adjusting the distance between the limit rod and the flipping plate, and adjusting the distance between the limit plate and the flipping plate according to the specifications of the wooden pallet, improving the stability of flipping the wooden pallet.

[0017] Optionally, the rotating gear is rotatably connected to the driving plate through a rotating shaft. A connection groove is provided at the end of the rotating shaft, and the cross section of the connection groove is non-circular. A connection cavity is provided in the rotating shaft. A connecting rod passes through the driving plate. The connecting rod passes through the connection cavity. A connection block matching the connection groove is provided at the end of the connecting rod. The connecting rod is slidably connected to the rotating shaft. A connection gear is provided on the connecting rod on the side away from the rotating shaft in the connection cavity. A rotating plate is rotatably connected in the connection cavity. A connection spring is provided in the connection cavity. Both ends of the connection spring are connected to the connection gear and the rotating plate. A fixing block matching the connection gear is fixedly provided on the inner wall of the connection cavity on the side away from the rotating shaft. When the connection spring is in a natural state, the fixing block is located in the tooth gap of the connection gear.

[0018] By adopting the above technical solution, when it is necessary to rotate the rotating gear, the connecting rod is moved towards the rotating shaft, the connecting block moves in the connecting groove, the connecting gear moves in the connecting cavity, the connecting gear is separated from the fixed block, the connecting spring is compressed, the connecting rod is rotated, driving the rotating shaft to rotate, so as to make the rotating gear rotate. After adjusting the position of the limiting plate, release the connecting rod, and the compressed connecting spring releases elastic force, pushing the connecting gear to move, so that the fixed block is inserted into the tooth gap of the connecting gear to prevent the connecting gear from rotating, thereby preventing the connecting rod and the rotating shaft from rotating, and improving the stability of the connection between the limiting plate and the driving plate.

[0019] Optionally, rubber pads are provided on both the turning plate and the limiting plate.

[0020] By adopting the above technical solution, the rubber pad has elasticity, protects the turning plate, the limiting plate and the wooden pallet, and avoids direct contact between the turning plate, the limiting plate and the wooden pallet.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] During the rotation of the driving plate, the connecting shaft rotates synchronously with the driving plate, the cam rotates, making the limiting rod move upward. The upper end of the limiting rod is located above the first conveying roller to block the wooden pallet conveyed on the first conveying assembly. When the driving plate rotates 90 degrees, the limiting rod is at the highest height. When the driving plate rotates 180 degrees, the limiting rod completes a lifting movement. The limiting rod moves to below the top of the first conveying roller, enabling the next wooden pallet to be conveyed along the first conveying assembly, avoiding the next wooden pallet from colliding with the turning mechanism during the turning process of the wooden pallet, and at the same time, after completing one turn, the next wooden pallet can be conveyed in time, improving the efficiency;

[0030] The following further describes the present application in detail with reference to all the drawings.

[0031] The embodiment of the present application discloses a flipping mechanism for wood pallet production.

[0032] Refer to Figure 1 , a flipping mechanism for wood pallet production, including a first conveying assembly 1, a second conveying assembly and a support frame 2. The support frame 2 is located between the first conveying assembly 1 and the second conveying assembly. A driving plate 3 is rotatably connected to the support frame 2. A driving motor 21 is installed on the support frame 2. The output shaft of the driving motor 21 is coaxially and fixedly connected to the driving plate 3. Flipping frames 4 are arranged on both sides of the driving plate 3. The first conveying assembly 1 includes a first conveying frame 11 and a plurality of first conveying rollers 12. The second conveying assembly includes a second conveying frame and a plurality of second conveying rollers. By rotating the first conveying rollers 12, the wood pallet is conveyed to the flipping frame 4 through the first conveying assembly 1. After being rotated by the driving plate 3, the wood pallet is flipped, and then the second conveying rollers rotate to convey the flipped wood pallet.

[0033] Refer to Figure 1 and Figure 2, the turning frame 4 includes a limiting plate 42 and a turning plate 41. The turning plate 41 is fixedly installed on the driving plate 3. The limiting plate 42 on the side close to the first conveying component 1 is located above the turning plate 41, and the limiting plate 42 on the side close to the second conveying component is located below the turning plate 41. Among them, the length of the limiting plate 42 and the turning plate 41 is less than the length of the wooden pallet. The wooden pallet passing through the first conveying component 1 is conveyed onto the turning frame 4. A part of the wooden pallet is located between the limiting plate 42 and the turning plate 41, and the other part is located on the first conveying component 1. The turning plate 41 is located below the wooden pallet, and the limiting plate 42 is located above the wooden pallet. When the driving plate 3 rotates, the turning plate 41 and the limiting plate 42 jointly clamp and turn the wooden pallet. After turning, a part of the wooden pallet is located on the second conveying component, and the other part is located between the turning plate 41 and the limiting plate 42. The second conveying rollers on the second conveying component continuously rotate, and the turned wooden pallet is conveyed through the second conveying component.

[0034] Refer to Figure 2 , on the mutually close sides of the two limiting plates 42, moving rods 43 are provided. The moving rods 43 are inserted into the driving plate 3 and are slidably connected to the driving plate 3. On the mutually close sides of the two moving rods 43, moving racks 431 are provided. A rotating gear 44 is rotatably connected in the driving plate 3, and the rotating gear 44 meshes with the two moving racks 431. Rotate the rotating gear 44 in the driving plate 3, drive the two moving rods 43 to move through the two moving racks 431, so that the two limiting plates 42 approach or move away from each other, adjust the distance between the limiting rod 8 and the turning plate 41, and adjust the distance between the limiting plate 42 and the turning plate 41 according to the specifications of the wooden pallet, thereby improving the stability of turning the wooden pallet.

[0035] Refer to Figure 2 and Figure 3, the rotating gear 44 is rotatably connected to the driving plate 3 through a rotating shaft 5. A connecting groove 51 is formed at the end of the rotating shaft 5, and the cross-section of the connecting groove 51 is non-circular. A connecting cavity 31 is formed in the rotating shaft 5. A connecting rod 6 penetrates through the driving plate 3. The connecting rod 6 passes through the connecting cavity 31. A connecting block that cooperates with the connecting groove 51 is provided at the end of the connecting rod 6. The connecting rod 6 is slidably connected to the rotating shaft 5. A connecting gear 61 is provided on the connecting rod 6 on the side of the connecting cavity 31 away from the rotating shaft 5. A rotating plate 32 is rotatably connected in the connecting cavity 31. A connecting spring 33 is provided in the connecting cavity 31. Both ends of the connecting spring 33 are connected to the connecting gear 61 and the rotating plate 32. A fixing block 34 that cooperates with the connecting gear 61 is fixedly provided on the inner wall of the connecting cavity 31 on the side away from the rotating shaft 5. When the connecting spring 33 is in a natural state, the fixing block 34 is located in the tooth gap of the connecting gear 61. When it is necessary to rotate the rotating gear 44, the connecting rod 6 is moved towards the rotating shaft 5. The connecting block moves in the connecting groove 51, and the connecting gear 61 moves in the connecting cavity 31. The connecting gear 61 is separated from the fixing block 34, and the connecting spring 33 is compressed. The connecting rod 6 is rotated to drive the rotating shaft 5 to rotate, so as to rotate the rotating gear 44. After adjusting the position of the limiting plate 42, the connecting rod 6 is released. The compressed connecting spring 33 releases elastic force to push the connecting gear 61 to move, so that the fixing block 34 is inserted into the tooth gap of the connecting gear 61 to prevent the connecting gear 61 from rotating, thereby preventing the connecting rod 6 and the rotating shaft 5 from rotating, and improving the stability of the connection between the limiting plate 42 and the driving plate 3.

[0036] Refer to Figure 2 , rubber pads 45 are provided on both the flipping plate 41 and the limiting plate 42. The rubber pads 45 are elastic and protect the flipping plate 41, the limiting plate 42 and the wooden pallet, avoiding direct contact between the flipping plate 41, the limiting plate 42 and the wooden pallet.

[0037] Refer to Figure 2 , Figure 4 and Figure 5, a support plate 7 is fixedly connected to the first conveying frame 11 and is located below the first conveying roller 12. A wheel groove 71 is formed in the support plate 7, and a cam 72 is rotatably connected in the wheel groove 71. The cross-section of the cam 72 is oval. The cam 72 is rotatably connected to the support plate 7 through a connecting shaft 73. The output shaft of the driving motor 21 is connected to the connecting shaft 73 through a connecting belt 74. When the driving plate 3 rotates, the connecting shaft 73 is driven to rotate through the connecting belt 74, so that the driving plate 3 and the connecting shaft 73 rotate synchronously. A rod groove 75 is formed in the support plate 7 in the vertical direction above. A limiting rod 8 is arranged in the rod groove 75. The limiting rod 8 is movably connected to the support plate 7. When the end of the limiting rod 8 abuts against the convex part of the cam 72, the end of the limiting rod 8 away from the cam 72 is located above the first conveying roller 12. The wooden pallet is conveyed to the turning frame 4 through the first conveying assembly 1. At this time, the shorter diameter side of the cam 72 abuts against the limiting rod 8, and the end of the limiting rod 8 is located below the top of the first conveying roller 12. The driving plate 3 is rotated. After the driving plate 3 rotates 180 degrees, the turning frame 4 loaded with the wooden pallet moves to one side of the second conveying assembly. The turned wooden pallet is conveyed through the second conveying assembly. During the rotation of the driving plate 3, the connecting shaft 73 and the driving plate 3 are rotated synchronously, the cam 72 rotates, so that the limiting rod 8 moves upward. The upper end of the limiting rod 8 is located above the first conveying roller 12 to block the wooden pallet conveyed on the first conveying assembly 1. When the driving plate 3 rotates 90 degrees, the limiting rod 8 is at the highest height. After the driving plate 3 rotates 180 degrees, the limiting rod 8 completes a lifting movement. The limiting rod 8 moves to below the top of the first conveying roller 12, so that the next wooden pallet is conveyed along the first conveying assembly 1.

[0038] Spring grooves 76 are formed in the support plate 7 on both sides of the rod groove 75. Spring plates 81 are arranged on the limiting rod 8 and are located in the spring grooves 76. Elastic springs 77 are arranged in the spring grooves 76 and are located above the spring plates 81. When the elastic springs 77 are in a natural state, the spring plates 81 are located at the bottom of the spring grooves 76. When the cam 72 rotates, during the process that the diameter part of the cam 72 in contact with the limiting rod 8 gradually increases, the limiting rod 8 gradually moves upward, and the elastic springs 77 are compressed. The compressed elastic springs 77 exert a downward elastic force on the spring plates 81. When the cam 72 rotates, during the process that the diameter part of the cam 72 in contact with the limiting rod 8 gradually decreases, the compressed elastic springs 77 release the elastic force and push the elastic plates downward, so that the limiting rod 8 moves downward, so that the end of the limiting rod 8 always abuts against the side wall of the cam 72, improving the stability.

[0039] The implementation principle of a turnover mechanism for wooden pallet production in an embodiment of this application is as follows: The wooden pallet conveyed by the first conveying component 1 is transported onto the turnover frame 4. A part of the wooden pallet is located between the limiting plate 42 and the turnover plate 41, and the other part is located on the first conveying component 1. The turnover plate 41 is located below the wooden pallet, and the limiting plate 42 is located above the wooden pallet. At this time, the shorter diameter side of the cam 72 abuts against the limiting rod 8, and the end of the limiting rod 8 is located below the top of the first conveying roller 12; when the driving plate 3 rotates, the turnover plate 41 and the limiting plate 42 jointly clamp and turnover the wooden pallet. After turnover, a part of the wooden pallet is located on the second conveying component, and the other part is located between the turnover plate 41 and the limiting plate 42. The second conveying roller on the second conveying component rotates continuously, and the turnover wooden pallet is conveyed through the second conveying component; during the rotation of the driving plate 3, the connecting shaft 73 rotates synchronously with the driving plate 3, and the cam 72 rotates, causing the limiting rod 8 to move upward. The upper end of the limiting rod 8 is located above the first conveying roller 12 to block the wooden pallet conveyed on the first conveying component 1. When the driving plate 3 rotates 90 degrees, the limiting rod 8 is at the highest height. After the driving plate 3 rotates 180 degrees, the limiting rod 8 completes a lifting movement, and the limiting rod 8 moves to below the top of the first conveying roller 12, enabling the next wooden pallet to be conveyed along the first conveying component 1, avoiding the next wooden pallet from colliding with the turnover mechanism during the turnover of the wooden pallet, and at the same time, after one turnover is completed, the next wooden pallet can be conveyed in time to improve efficiency.

[0040] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
