[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1 - 3, the present utility model provides a technical solution: a large and small package sorting robot, including a base 1 and a workbench 2. The workbench 2 is fixedly installed on the top of the base 1. A motor 3 is fixedly installed on the surface of the workbench 2. The motor 3 is powered on. A conveyor belt 4 is arranged on the surface of the workbench 2. The conveyor belt 4 is sleeved on the output end of the motor 3. An opening is formed on the surface of the workbench 2. A revolving door 5 is rotatably installed at the opening. An elastic device 6 is arranged between the revolving door 5 and the workbench 2. A sloping plate 13 is fixedly installed on the surface of the workbench 2. The workbench 2 is divided into left and right sides by the sloping plate 13. A first buffer plate 11 is arranged on the surface of the sloping plate 13. A second buffer plate 12 is arranged on the surface of the right workbench 2. Springs are arranged at the bottoms of the first buffer plate 11 and the second buffer plate 12. A support rod 7 is slidably installed on the surface of the workbench 2. One end of the support rod 7 close to the opening on the surface of the workbench 2 is rotatably installed with a push plate 8. The push plate 8 rotates unidirectionally. A runner 9 is fixedly installed at the output end of the motor 3. A movable rod 10 is hinged on the surface of the runner 9. One end of the movable rod 10 far from the runner 9 is hinged with the support rod 7. When the large package passes through the surface of the revolving door 5, it squeezes the revolving door 5 to rotate and open the opening on the surface of the workbench 2, and falls through the opening onto the surface of the sloping plate 13.

[0021] One end of the workbench 2 close to the second buffer plate 12 is set as an inclined surface. The small package passing through the surface of the revolving door 5 falls from the workbench 2 onto the surface of the base 1.

[0022] The hinge point of the movable rod 10 and the runner 9 is located at a position far from the edge of the surface of the runner 9. When the runner 9 rotates, it drives the movable rod 10 to move reciprocally.

[0023] The revolving door 5 is parallel to the base 1. The push plate 8 is arranged vertically. When the push plate 8 moves along with the support rod 7, it pushes the package on the surface of the workbench 2 towards the direction of the revolving door 5. When the push plate 8 returns to its original position, it touches the surface of the package and rotates.

[0024] The elastic device 6 includes a rotating shaft 61 and an adjusting ring 62. The rotating shaft 61 is fixedly connected with the revolving door 5. The rotating shaft 61 is sleeved with the adjusting ring 62. A torsion spring 63 is fixedly installed between the rotating shaft 61 and the adjusting ring 62. A stop rod 64 is fixedly installed on the surface of the adjusting ring 62. A fixing plate 65 is fixedly installed on the surface of the workbench 2 near the rotating shaft 61. A plurality of clamping blocks 66 are fixedly installed on the surface of the fixing plate 65. By rotating the adjusting ring 62, the torsion spring 63 is deformed, and the elastic force of the torsion spring 63 on the rotating shaft 61 is changed.

[0025] The distance between adjacent clamping blocks 66 on the surface of the fixing plate 65 is greater than the cross-sectional diameter of the stop rod 64. When the stop rod 64 moves between the clamping blocks 66, the adjusting ring 62 is clamped tightly.

[0026] Turn on the power to start the motor 3. The output end of the motor 3 drives the conveyor belt 4 to rotate. Place a batch of packages on the surface of the conveyor belt 4. Through the rotating conveyor belt 4, the packages on the surface are pushed to the side of the revolving door 5. The output end of the motor 3 rotates to drive the rotating wheel 9 to rotate. The rotating rotating wheel 9 drives the movable rod 10 to move reciprocally. The moving movable rod 10 pulls the support rod 7 to move reciprocally. The support rod 7 drives the push plate 8 to move towards the revolving door 5. The push plate 8 pushes the surrounding packages to the surface of the revolving door 5. Since there is an elastic device 6 between the revolving door 5 and the workbench 2, when the package on the surface of the revolving door 5 is a large package with a large weight, the gravity of the package is greater than the elastic force provided by the elastic device 6 for the revolving door 5. The revolving door 5 rotates under the action of the gravity of the package to open the opening on the surface of the workbench 2, and the package falls through the opening to the surface of the inclined plate 13 and slides to the left base 1 through the inclined surface of the inclined plate 13. When the package falls to the surface of the inclined plate 13, the first buffer plate 11 buffers the impact force when the package falls, avoiding damage to large packages with large weights after sorting. When the package on the surface of the revolving door 5 falls, the revolving door 5 resets to be flush with the workbench 2 under the elastic force of the elastic device 6. The support rod 7 continuously drives the push plate 8 to move to push the packages on the surface of the workbench 2 to move. When a small package with a light weight moves above the revolving door 5, the weight of the package is not enough to open the revolving door 5, so that the small package will continue to move until it falls onto the second buffer plate 12 on the surface of the base 1 through the inclined surface on the right side of the workbench 2, completing the classification of large and small packages in the batch of packages.

[0027] The elastic device 6 is arranged on the surface of the workbench 2. The rotating shaft 61 is the rotating shaft for the revolving door 5 to rotate on the surface of the workbench 2. The torsion spring 63 provides elasticity for the rotating shaft 61. Rotate the adjusting ring 62 and move the rotated adjusting ring 62 towards the fixed plate 65. The moving adjusting ring 62 drives the stop rod 64 to move. The moved stop rod 64 contacts the block 66 on the surface of the fixed plate 65 to clamp the adjusting ring 62. By rotating the adjusting ring 62, the torsion spring 63 generates different degrees of deformation, changing the elastic force of the torsion spring 63 on the rotating shaft 61, adjusting the maximum bearing capacity on the surface of the revolving door 5, and adjusting the classification standard for large packages.

[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
