[0023] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural methods and implementation methods. Therefore, the following specific embodiments and drawings are only illustrative of the technical solution of the present invention and should not be regarded as the entire present invention or as a limitation or restriction of the technical solution of the present invention.

[0024] like Figure 1 As shown, as a conveying device that can switch between upper and lower layers of the present invention, it includes a front-end belt conveyor 1, and the side of the front-end belt conveyor 1 is hinged with a flip belt conveyor 2, and the flip belt conveyor 2 performs circular motion with a flip fulcrum 201 located on the front-end belt conveyor 1 as the center of the circle. A proximity switch 202 is provided at the hinge between the front-end belt conveyor 1 and the flip belt conveyor 2, and the proximity switch 202 allows the flip belt conveyor 2 to rotate at an angle of 0-50°. The proximity switch 202 is used to limit the flip belt conveyor 2 within a certain range, thereby improving the stability of the flip belt conveyor 2 and improving safety.

[0025] A driving motor 203 is fixedly provided on the front end belt conveyor 1, and a screw rod 204 is connected to the output end of the driving motor 203 for transmission. A moving block 205 is threadedly provided on the screw rod 204, and a connecting rod 208 is hinged on the top of the moving block 205. The top of the connecting rod 208 is hinged to the bottom of the flip belt conveyor 2 away from the front end belt conveyor 1. The driving motor 203 drives the moving block 205 to move on the screw rod 204, thereby driving the connecting rod 208 to move and further driving the flip belt conveyor 2 to rotate.

[0026] Limit switches 206 are provided on both sides of the moving block 205 on the screw rod 204. When the moving block 205 moves to the limit switch 206 on one side, the flip belt conveyor 2 is in a horizontal state, and when the moving block 205 moves to the limit switch 206 on the other side, the angle between the flip belt conveyor 2 and the horizontal direction is 55°. A limit rod 207 is fixed on the front end belt conveyor 1, and when the bottom of the flip belt conveyor 2 hits the top of the limit rod 207, the angle between the flip belt conveyor 2 and the horizontal direction is 60°. If the proximity switch 202 fails, when the moving block 205 runs to touch the limit switch 206, the equipment stops running. If both the proximity switch 202 and the limit switch 206 fail, the limit rod 207 stops the equipment operation when it runs to the extreme position, thereby greatly improving the safety of the operation of the entire equipment.

[0027] like Figure 2 As shown, the flip belt conveyor 2 is provided with a rear end belt conveyor 3 and a rear end belt conveyor 2 4 in the upper and lower directions on the side away from the front end belt conveyor 1, and the sides of the rear end belt conveyor 1 3 and the rear end belt conveyor 2 4 close to the flip belt conveyor 2 are all located on the rotating circumference of the flip belt conveyor 2, ensuring that the distance between the flip belt conveyor 2 and the rear end belt conveyor is not too large to cause the parcel to fall, thereby ensuring the stable conveying work, and the horizontal height of the rear end belt conveyor at the top is not higher than the horizontal height of the front end belt conveyor 1, so that the parcel can improve the conveying effect through its own gravity, and the side of the flip belt conveyor 2 close to the rear end belt conveyor and the side of the rear end belt conveyor close to the flip belt conveyor 2 are both set to be arc-shaped, and the two are completely fitted together. The movement trajectory of the flip belt conveyor 2 close to the side of the rear end belt conveyor is an arc, which further reduces the distance between the flip belt conveyor 2 and the rear end belt conveyor and increases the scope of application.

[0028] During use, the properties of packages in different time periods are different, and the overturning belt conveyor 2 is connected to different rear-end belt conveyors for processing. This can not only achieve the purpose of improving the equipment reuse rate, but also reduce the site use cost.

[0029] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the scope of protection of the present invention.
