[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the 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 of the embodiments.

[0016] Refer to Figures 1-4As shown in the figure, a steering gear includes a frame 1. Two groups of first transmission shafts 2 are symmetrically arranged on the frame 1. A first conveyor belt 3 is arranged on the first transmission shafts 2. One end of the first transmission shaft 2 passes through the frame 1 and is connected to a first belt 4. The other end of the first belt 4 is connected to a first driving motor 5. On both sides of the upper end of the frame 1, a guiding mechanism with adjustable differential is provided, and a straightening mechanism is arranged on the frame 1 on one side of the guiding mechanism.

[0017] The guiding mechanism includes a fixed plate 6, an electric push rod 7, a moving box 8, a clamping roller 9 and a third motor 10. Fixed plates 6 are arranged on both sides of the surface of the frame 1. Electric push rods 7 are arranged on the fixed plates 6. One end of the electric push rod 7 is connected to the moving box 8. Clamping rollers 9 are symmetrically arranged in the moving box 8. The two clamping rollers 9 are connected by a transmission belt. The moving box 8 is rotatably connected to the clamping roller 9. One end of one side of the clamping roller 9 extends out of the moving box 8 and is connected to the third motor 10. When the direction of the bottle body is normal, the electric push rod 7 extends, driving the moving box 8 to move. At the same time, the third motor 10 works, driving the clamping roller 9 to rotate, so as to guide the bottle body.

[0018] The straightening mechanism includes a second driving motor 20, a second transmission shaft 17, a second conveyor belt 18, a third driving motor 22, a third conveyor belt 24, a third transmission shaft 23, a second belt 19 and a third belt 25. Second transmission shafts 17 are symmetrically arranged on one side of the frame 1. A second conveyor belt 18 is arranged on the second transmission shafts 17. One end of the second transmission shaft 17 passes through the frame 1 and is connected to the second belt 19. The other end of the second belt 19 is connected to the second driving motor 20. Third transmission shafts 23 are symmetrically arranged on the other side of the frame 1. A third conveyor belt 24 is arranged on the third transmission shafts 23. One end of the third transmission shaft 23 passes through the frame 1 and is connected to the third belt 25. The other end of the third belt 25 is connected to the third driving motor 22. Infrared sensors 16 are symmetrically arranged on the inner wall of the frame 1. A controller is respectively connected to the infrared sensors 16, the first driving motor 5, the second driving motor 20 and the third driving motor 22. When the bottle inlet direction is incorrect, the electric push rod 7 contracts. At this time, the rotation speed of the second driving motor 20 decreases, and at the same time, the rotation speed of the third driving motor 22 increases, so that one end of the bottle body lags behind and the other end leads, so that the bottle can be rubbed by the differential of the two synchronous belts on both sides to achieve the purpose of making the bottle inclined.

[0019] A chute is provided on the surface of the frame 1. A servo motor 11 connected to the controller is provided in the chute. The output shaft of the servo motor 11 is connected to a threaded rod 12. A slider 13 is provided on the threaded rod 12. A cylinder 14 is provided on one side of the slider 13. The other end of the cylinder 14 is connected to a push plate 15. When the servo motor 11 works, it drives the slider 13 on the threaded rod 12 to move. At the same time, the cylinder 14 extends, driving the push plate 15 to squeeze inward, so as to straighten the inclined bottle body while moving. Infrared sensors 16 are symmetrically provided on the inner wall of the frame 1. When the infrared sensors 16 sense that there is a bottle passing on the conveyor belt, they transmit signals to make the guiding mechanism and the straightening mechanism work under the drive of the controller to guide and straighten the bottle. In addition, support columns 21 are provided at the four corners of the bottom of the frame 1. A partition is provided on the support columns 21, and the support columns 21 play a role of fixing and supporting.

[0020] Working principle: When the present utility model is in use, the first driving motor 5 works to drive the first conveyor belt 3 on the first belt 4 to drive. When the infrared sensor 16 senses and detects that there is a bottle passing by, the controller drives the second driving motor 20 to reduce the rotation speed and at the same time drives the third driving motor 22 to increase the rotation speed, so that one end of the bottle body lags behind and the other end leads, so that it can be in an inclined state. At the same time, when adjusting the bottle, the speed of the first transmission shaft 2 at the other end of the frame 1 slows down, so as to pull the adjacent bottles behind a certain distance, facilitating the turning of the bottles that cannot be turned. After the inclination is completed, the controller can drive the servo motor 11 to work, driving the slider 13 on the threaded rod 12 to move. At the same time, the cylinder 14 extends, driving the push plate 15 to squeeze inward, so as to straighten the inclined bottle body, making the subsequent processing more convenient and improving the work efficiency.

[0021] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
