[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Embodiment 1:

[0027] Please refer to Figure 1 and Figure 5 , a rotary conveying mechanism, comprising: a workbench 1, a turntable 2 rotatably arranged on the workbench 1, a driving member 12 installed on the workbench 1, the output end of the driving member 12 is connected to the turntable 2 for driving the turntable 2 to rotate, and a conveyor roller 3 is arranged above the turntable 2.

[0028] Please refer to Figure 5 , the driving member 12 includes a support platform 122 and a power mechanism 121 for driving the support platform 122 to rotate. The power mechanism 121 refers to a motor and a transmission component (transmission gear), the transmission component is connected to the support platform 122, and the motor is used to drive the transmission component to work, driving the support platform 122 to rotate; the support platform 122 is rotatably installed on the workbench 1, and the turntable 2 is installed above the support platform 122.

[0029] Please refer to Figure 1 and Figure 4, a slot is provided above the turntable 2. A telescopic member 8 is installed in the inner cavity of the slot. A blocking member 4 is installed on the moving end of the telescopic member 8 for driving the blocking member 4 to move up and down. A contact switch is provided on the blocking member 4, and the contact switch is electrically connected to the driving member 12 through a wire. A telescopic mechanism 6 (such as an electric, hydraulic or pneumatic telescopic rod and other telescopic devices) is provided on the workbench 1. A baffle 7 is installed on the moving end of the telescopic mechanism 6 (the telescopic mechanism 6 can drive the baffle 7 to move up and down). The baffle 7 is located at the feeding end of the turntable 2 (the baffle 7 is between the turntable 2 and the external transmission device). The telescopic mechanism 6 is electrically connected to the contact switch through a wire. A PLC controller (model number: TPC24 - 24TD) is installed on the workbench 1 for electrically connecting with the contact switch, the telescopic mechanism 6, and the driving member 12. After the contact switch is pressed, the PLC controller receives the signal to control the operation of the telescopic mechanism 6 and the driving member 12. And the PLC controller is also used to control the telescopic mechanism 6 and the driving member 12 to reset.

[0030] In this embodiment, as a further optimized solution, please refer to Figure 6 , an installation groove is provided above the baffle 7. A roller 13 is rotatably provided in the installation groove. The transmission direction of the roller 13 is opposite to the transmission direction of the conveying roller 3. A driving motor 14 is installed on the baffle 7. The output shaft of the driving motor 14 is connected to the roller 13 for driving the roller 13 to rotate. During the process that the telescopic mechanism 6 drives the baffle 7 to move upward to separate the turntable 2 from the external transmission device, the driving motor 14 will be powered on to drive the roller 13 to rotate. If there are goods on both the turntable 2 and the external transmission device at the same time, when the baffle 7 moves upward, it will lift the goods, which is likely to cause the goods to fall. Through the rotation of the roller 13, the lifted goods will be transported, and the goods will be transported to the external transmission device to protect the goods.

[0031] In this embodiment, as a further optimized solution, please refer to Figure 6 , Figure 7 and Figure 8, on one side of the baffle 7 facing the turntable 2, a support block 18 is hinged, and a support spring is installed between the support block 18 and the baffle 7; on one side of the baffle 7 facing the turntable 2, a mounting hole is opened, the mounting hole is located below the support block 18, and a pressing member 19 is slidably inserted into the inner cavity of the mounting hole, and an elastic member is installed between the mounting hole and the pressing member 19; a second touch switch 20 is provided on the baffle 7, and the second touch switch 20 is located inside the pressing member 19 (when the pressing member 19 moves closer to the baffle 7, it can press the second touch switch 20), and the second touch switch 20 is electrically connected to the drive motor 14; when the baffle 7 lifts the goods between the turntable 2 and the external transmission device, the goods will tilt towards the external transmission device or towards the turntable 2; when the goods tilt towards the external transmission device, the roller 13 rotates normally and transports the goods onto the external transmission device; if the goods tilt towards the turntable 2, the goods will press the support block 18, causing the support block 18 to rotate and press the pressing member 19, and using the pressing member 19 to squeeze the second touch switch 20, so that the drive motor 14 drives the conveying roller 3 to rotate in the reverse direction, and transports the goods onto the turntable 2, so that the goods fall onto the turntable 2, so that the goods can be transported to the corresponding position according to the position of the goods (whether the goods are close to the turntable 2 or close to the external transmission device); and the drive motor 14 is a servo motor (model: EDSMT-2T110-020A).

[0032] In this embodiment, as a further optimized solution, please refer to Figure 6 , an installation seat 5 is provided on the workbench 1, a moving groove 15 is opened on the installation seat 5, the extending direction of the moving groove 15 is the same as the transmission direction of the conveying roller 3, a moving member 17 is slidably arranged in the moving groove 15, a driving mechanism 16 is installed in the moving groove 15, and the moving end of the driving mechanism 16 is connected to the moving member 17 for driving the moving member 17 to move inside the moving groove 15. The telescopic mechanism 6 is installed on the moving member 17, and the driving mechanism 16 is electrically connected to the second touch switch 20; after the second touch switch 20 is pressed, the driving mechanism 16 is powered on to work, so that the moving member 17 slides in the moving groove 15, and the baffle 7 moves away from the turntable 2. When transporting the goods onto the turntable 2, by moving the baffle 7, the distance between the baffle 7 and the blocking member 4 is increased to ensure that the goods can be completely transported onto the turntable 2; the second touch switch 20 is electrically connected to the PLC controller, and the PLC controller is electrically connected to the driving mechanism 16 and the drive motor 14. After the second touch switch 20 is pressed, the PLC controller receives the signal and controls the driving mechanism 16 and the drive motor 14 to work.

[0033] In summary, the specific method of cargo transmission is as follows: The cargo is transmitted to the turntable 2 by an external transmission device. The conveying roller 3 rotates to transmit the cargo into the interior of the turntable 2 until the cargo contacts the blocking member 4. The cargo squeezes the contact switch on the blocking member 4, causing the driving member 12 to be powered on and work, driving the turntable 2 to rotate. After turning with the cargo, the telescopic member 8 drives the blocking member 4 to move downward, causing the blocking of the cargo by the blocking member 4 to disappear. Then, after the conveying roller 3 transmits the cargo away from above the turntable 2, the turntable 2 resets, and the telescopic member 8 drives the blocking member 4 to move upward and reset to continue working. After the contact switch is pressed, the telescopic mechanism 6 drives the baffle 7 to move upward to separate the turntable 2 from the external transmission device and prevent the cargo from continuing to enter the turntable 2. Moreover, after the baffle 7 moves upward first, the driving member 12 drives the turntable 2 to rotate.

[0034] Embodiment 2:

[0035] As a further optimized solution, please refer to Figure 3 and Figure 4 , the telescopic member 8 is an electric telescopic rod. An installation member 10 is provided on the workbench 1. A first touch switch 11 is provided on the installation member 10. The first touch switch 11 is electrically connected to the electric telescopic rod through a wire. A pressing block 9 is provided on the turntable 2. The installation member 10 is detachably connected to the workbench 1 (by means of threaded connection or snap connection), so that the installation member 10 can be removed from the workbench 1 to adjust the position of the installation member 10 to adapt to the rotation direction of the turntable 2. When the driving member 12 drives the turntable 2 to rotate and after the turntable 2 moves to a predetermined area, the pressing block 9 presses the first touch switch 11 on the installation member 10, causing the electric telescopic rod to be powered on and work (i.e., the electric telescopic rod contracts), driving the blocking member 4 to move downward. Moreover, the first touch switch 11, the electric telescopic rod and the PLC controller are electrically connected. After receiving the information that the first touch switch 11 is pressed, the PLC controls the electric telescopic rod to work, and the PLC controller also controls the electric telescopic rod to work and reset (i.e., drive the blocking member 4 to move upward and reset).

[0036] Embodiment 3:

[0037] As a further optimized solution, please refer to Figure 2 , the telescopic member 8 includes an installation sleeve 81, a movable rod 82, an elastic element and a connecting rope 83. The installation sleeve 81 is installed on the workbench 1. The movable rod 82 is slidably inserted into the inner cavity of the installation sleeve 81. The blocking member 4 is installed above the movable rod 82 and moves up and down through the movable rod 82 to drive the blocking member 4 to move up and down. The elastic element is arranged between the movable rod 82 and the installation sleeve 81. The connecting rope 83 is installed between the movable rod 82 and the workbench 1. During the rotation of the turntable 2, since one end of the connecting rope 83 is fixedly connected to the workbench 1, the movable rod 82 will be pulled downward, driving the blocking member 4 to move downward. After the turntable 2 rotates to a predetermined area, the blocking of the cargo by the blocking member 4 just disappears, and the cargo is transmitted away by the conveying roller 3.
