[0017] Please see Figure 1-6 This embodiment is an automatic flipping device for steel plate production, including two horizontally arranged conveyor slides 1. The conveyor slides 1 are used to convey steel plates. A stepping pusher mechanism 2 is provided below the conveyor slides 1. The stepping pusher mechanism 2 is used to push the steel plates on the conveyor slides 1 one by one forward. A flipping mechanism is provided at the front end of the conveyor slides 1. A conveyor belt 5 is provided in front of the flipping mechanism. The conveyor belt 5 is used to catch the steel plates flipped by the flipping mechanism and continue to convey them forward. The flipping mechanism includes two turntables 3. Several material troughs are evenly distributed on the turntables 3. The material troughs are used to hold steel plates. The two turntables 3 are respectively set on the outside of the two conveyor slides 1. A drive shaft 4 is installed at the center of the two turntables 3. One end of the drive shaft 4 is connected to an intermittent drive mechanism. The intermittent drive mechanism cooperates with the stepping pusher mechanism 2 so that the turntables 3 pick up one steel plate from the conveyor slides 1 every time they rotate.

[0018] Preferably, the stepping pusher mechanism 2 includes a pusher frame, with a plurality of push blocks 25 arranged at the upper end of the pusher frame along the direction of the conveying slide 1. The push blocks 25 are evenly distributed between each other. The lower end of the pusher frame is provided with two legs 24. Each of the two legs 24 is provided with a support base 22 at its bottom end. A rotating shaft is installed inside the support base 22. A connecting rod 23 is installed between the rotating shaft and the leg 24. One end of the connecting rod 23 is rotatably connected to the rotating shaft, and the other end is rotatably connected to the leg 24. One end of one of the rotating shafts is connected to a drive motor 21.

[0019] Preferably, the intermittent drive mechanism includes a synchronous motor 6, a drive sprocket, a driven sprocket, a timer, and a controller. The drive sprocket is connected to the output end of the synchronous motor 6, the driven sprocket is fixedly connected to the drive shaft 4, and a circulating chain is wound between the drive sprocket and the driven sprocket. The controller is used to control the synchronous motor 6 to start or stop, and the timer is electrically connected to the synchronous motor 6.

[0020] Preferably, each pusher block 25 has a pusher plate 26 at its front end, and the pusher plate 26 extends upward in the vertical direction. Preferably, the conveyor belt 5 is disposed between the two turntables 3, and the conveying height of the conveyor belt 5 is lower than the conveying height of the conveyor chute 1.

[0021] The working principle of this utility model is as follows: Steel plates are conveyed forward through the conveyor slide 1. The stepping pusher mechanism 2 pushes the steel plates on the slide forward at certain intervals. The speed of the drive motor 21 of the pusher mechanism and the synchronous motor 6 of the intermittent drive mechanism are coordinated. When one of the material slots of the turntable 3 is aligned with the conveyor slide 1, the stepping motor stops. At the same time, the pusher mechanism pushes the steel plate on the slide forward one station, so that the first steel plate is pushed into the material slot. Then the stepping motor moves to make the turntable 3 rotate at a fixed angle. At this time, the next material slot is aligned with the conveyor slide 1, and the pusher mechanism sends the next steel plate into the material slot again. When the turntable 3 rotates 180°, the steel plate in the material slot is also flipped 180°. The steel plate will slide off the material slot due to its own gravity and onto the conveyor belt 5. The conveyor belt 5 immediately conveys the steel plate forward to the next process. By repeating this action, the steel plates on the production line can be flipped one by one.

[0022] This invention sets the working interval of the synchronous motor 6 using a timer. Each time the timing time t1 is reached, a signal is sent to the controller, which controls the synchronous motor 6 to start. At the same time, the timer counts down to t2. When t2 is reached, a signal is sent to the controller to stop the synchronous motor 6. The pushing interval of the pushing mechanism is adjusted by controlling the speed of the drive motor 21, so that the pushing mechanism matches the rotation interval of the turntable 3 according to the actual situation.

[0023] It should be noted that setting a timer in the control circuit of the synchronous motor 6 is within the scope of existing technology, so this utility model will not elaborate on it.
