Description

Technical Field

[0001] The utility model relates to the technical field of turnover mechanisms, in particular to a turnover mechanism for an automatic turning machine. Background Technique

[0002] During the process of processing a plate, usually only one side of the plate can be processed at the same time. When processing the other surface of the plate, the plate often needs to be turned over. The manual turning efficiency is relatively low. Therefore, a turning mechanism is usually used to turn over the plate. Before turning over the plate, the turning mechanism usually needs to fix the plate. However, the fixing device in the existing turning mechanism usually fixes the plate rigidly by applying pressure to the surface of the plate. During the fixing process, the surface of the plate often receives a large pressure. For relatively fragile plates, this fixing method usually causes damage to the plate. Moreover, its fixing device usually can only fix plates of a specific size, so its application range is small, which is not conducive to actual use.

[0003] For example, an automatic turning mechanism with the publication number of CN212820632U includes a support table. Four telescopic rods distributed in a rectangle are fixedly installed on the top of the support table. Rotation holes are respectively formed on the surfaces of two corresponding telescopic rods. A first rotating shaft and a second rotating shaft are respectively rotatably installed in the two rotation holes. A turning bracket is fixedly installed at one end of the first rotating shaft and one end of the second rotating shaft. Hydraulic rods are installed on both the first rotating shaft and the second rotating shaft. Push rods are fixedly installed in both of the two hydraulic rods. Fixing blocks are fixedly connected to one ends of the two push rods far away from the hydraulic rods. Two sliding grooves are formed on both sides of the turning bracket. Sliding rods are fixedly installed on the inner walls on both sides of the two sliding grooves. This technical solution also has the above-mentioned technical problems. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-3 , a flipping mechanism for an automatic flap machine, including a base 1. Above the base 1, there are several movable motors two 11. The specific number of the motors two 11 is two, and the two motors two 11 will start or stop simultaneously. One side of the motor two 11 is fixedly installed with a rotating shaft two 12. One end of the rotating shaft two 12 away from the motor two 11 is installed with a housing 13. Starting the motor 11 to rotate the rotating shaft two 12 will drive the housing 13 to rotate together. On one side of the housing 13 away from the rotating shaft two 12, there are several vertically movable fixing plates 26. The specific number of the fixing plates 26 is two.

[0022] On one side of the housing 13 away from the rotating shaft two 12, there is an opening. Inside the housing 13, a bidirectional threaded rod 15 is installed through a bearing two 14. The outer ring of the bearing two 14 is installed inside the housing 13, and the bidirectional threaded rod is installed on the inner ring of the bearing two 14. On the top of the housing 13, a motor three 16 is installed. The bottom of the motor three 16 is installed with a rotating shaft three 17. The rotating shaft three 17 extends downward and passes through the top wall of the housing 13. The bottom of the rotating shaft three 17 is connected to the top of the bidirectional threaded rod 15. Starting the motor three 16 to rotate the rotating shaft three 17 will drive the bidirectional threaded rod 15 to rotate together.

[0023] The surface of the bidirectional threaded rod 15 is provided with two different threads. The bidirectional threaded rod 15 is threadedly connected with several sliders two 18. The specific number of the sliders two 18 is two, and the two sliders two 118 are respectively threadedly connected to the two threads on the surface of the bidirectional threaded rod 15. One side of the slider two 18 facing the opening of the housing 13 is fixedly installed with a connecting block 19. One side of the connecting block 19 away from the slider two 18 is installed with a fixing frame 20. When the bidirectional threaded rod 15 rotates, the two sliders two 18 will move in opposite directions on the bidirectional threaded rod 15 at the same time and drive the fixing frame 20 to move, changing the distance between the two fixing frames 20 to clamp and fix the plate.

[0024] Inside the fixing frame 20, there is a moving plate 21. Inside the fixing frame 20, there are several springs 22. The top of the springs 22 is connected to the bottom of the moving plate 21. The springs 22 will push the moving plate 21 to move continuously through the elastic force. On the left and right side walls of the fixing frame 20, there are chutes two 23. Inside the chutes two 23, there are sliders three 24 slidably connected. One side of the two sliders three 24 is respectively connected to the left and right sides of the moving plate 21. When the moving plate 21 moves inside the fixing frame 20, it will drive the sliders three 24 to move inside the chutes two 23.

[0025] A connecting plate 25 is installed on the top of the moving plate 21. The connecting plate 25 extends upward and passes through the top wall of the fixing frame 20. The top of the connecting plate 25 is connected to the bottom of the fixing plate 26. When the moving plate 21 moves within the fixing frame 20, it will drive the fixing plate 26 to move through the connecting plate 25, changing the distance between the two connecting plates 25. A rubber pad 27 is installed on the side of the fixing plate 26 away from the connecting plate 25. The rubber pad 27 has a certain elasticity, which can avoid directly applying pressure to the plate when fixing the plate, protecting the plate. At the same time, the surface of the rubber pad 27 is relatively rough, which can increase the friction between the rubber pad 27 and the plate, improving the fixing effect.

[0026] A first motor 2 is installed on the top of the base 1. Rotating shafts 3 are installed on both sides of the left side of the first motor 2. Two mounting seats 4 are installed on the top of the base 1. The two mounting seats 4 are respectively located on the left and right sides of the first motor 2. An outer ring of a first bearing 5 is installed on the side of the mounting seat 4 facing the first motor 2. A threaded rod 6 is installed on the inner ring of the first bearing 5. One end of the threaded rod 6 away from the mounting seat 4 is connected to one end of the rotating shaft 3 away from the first motor 2. Starting the first motor 2 to rotate the rotating shaft 3 will drive the threaded rod 6 to rotate.

[0027] A moving block 7 is threadedly connected to the threaded rod 6. Two first chutes 8 are formed in the base 1. A first slider 9 is slidably connected in the first chute 8. The top of the first slider 9 is connected to the bottom of the moving block 7, which can prevent the moving block 7 from rotating. When the threaded rod 6 rotates, the moving block 7 will move on the threaded rod 6 and drive the first slider 9 to move in the first chute 8, changing the distance between the two moving blocks 7 and indirectly changing the distance between the two housings 13. The first slider 9 can also limit the moving range of the moving block 7 through its movable range in the first chute 8. A vertically upward electric push rod 10 is installed on the top of the moving block 7. The output end of the electric push rod 10 is connected to the bottom of the second motor 11. Starting the electric push rod 10 can control the up and down movement of the second motor 11 and indirectly drive the housing 13 to move up and down.

[0028] In use, the user can start motor 1-2 according to the size of the plate to rotate rotating shaft 1-3 and threaded rod 6, so that two moving blocks 1-7 move simultaneously, driving two electric push rods 10 to approach each other, changing the distance between two housings 13. Subsequently, start electric push rod 10 to drive motor 2-11 to move up and down, changing the height of housing 13. Then place the plate between four rubber pads 27. After that, start motor 3-16 to rotate rotating shaft 3-17 and drive bidirectional threaded rod 15 to rotate, so that two sliders 2-18 move on bidirectional threaded rod 15, and drive fixed frame 20 to move through connecting block 19, changing the distance between two fixed frames 20, making rubber pad 27 contact the plate. Subsequently, the elastic force generated by spring 22 makes moving plate 21 move, driving fixing plate 26 and rubber pad 27 to move in the direction of the plate and closely contact it, making rubber pad 27 closely contact the plate to fix the plate. After that, by starting motor 2-11 to rotate rotating shaft 2-12, housing 13 can be driven to rotate to turn over the plate.
