[0027] Referring to the attached Figures 1-5 , a two-station belt drum rotating device includes a cam divider main body 1. A rotating power motor 2 is provided on one side of the cam divider main body 1. The cam divider main body 1 drives the rotating power motor 2 to rotate. A transmission assembly is provided inside the rotating power motor 2. A rotating support platform 3 is provided on the top of the cam divider main body 1. The rotating power motor 2 drives the horizontal rotation of the rotating support platform 3 through the transmission assembly. A power machine box 4 is installed on the top of the rotating support platform 3.

[0028] In this embodiment, a cam sensor device 7 is installed on the other side of the cam divider body 1, and an induction cam 8 is provided outside the cam sensor device 7.

[0029] It should be noted that through the cooperation of the induction cam 8 and the cam sensor device 7, the accurate rotation is precisely controlled by the angle rotation control system, and the rotation accuracy error is small.

[0030] In this embodiment, the transmission assembly includes an input shaft 9. One end of the input shaft 9 is connected to the output end of the rotary power motor 2. A surface cam 10 is connected to the outside of the input shaft 9. The input shaft 9 and the surface cam 10 are driven by a keyway. There is an output table on the top of the cam divider body 1. A turntable 11 is installed on the output table. The inside of the turntable 11 is connected to an output shaft 12. The top end of the output shaft 12 is connected to the bottom end of the rotary support platform 3. There are multiple cam followers 13 inside the turntable 11. The surface cam 10 cooperates with the cam followers 13. The rotation of the surface cam 10 drives the movement of the multiple cam followers 13 to be converted into the rotational movement of the rotary support platform 3. There are two specific areas on the surface cam 10 to form a complete 360 degrees.

[0031] It should be noted that by driving the rotation of the surface cam 10 through the rotation of the input shaft 9, the cooperation between the surface cam 10 and the cam followers 13 causes it to move, driving the turntable 11 to rotate. The turntable 11 drives the output shaft 12 to drive the rotary support platform 3 to perform horizontal rotation, converting the continuous rotation of the input shaft 9 into the smooth intermittent rotation of the turntable 11. The acceleration and deceleration movements of the turntable 11 are controlled by the cam followers 13, and gapless positioning is achieved on the turntable 11.

[0032] In this embodiment, both sides of the power chassis 4 are connected with rotating shafts, and a first rotating drum 5 and a second rotating drum 6 are respectively connected to the ends of the two rotating shafts.

[0033] It should be noted that the two rotating shafts can be driven to rotate by starting the power chassis 4, and then the first rotating drum 5 and the second rotating drum 6 are driven to rotate.

[0034] The working principle of the present utility model: When the device is in use, the cam divider body 1 connected is rotated by driving the rotation of the surface cam 10 through the rotary power motor 2. While the input shaft 9 rotates, it drives the rotation of the surface cam 10. The surface cam 10 cooperates with multiple cam followers 13 at the bottom of the turntable 11, causing the surface cam 10 to drive the cam followers 13 to start moving, driving the turntable 11 to rotate. The turntable 11 drives the output shaft 12 to rotate, so that the rotary support platform 3 performs horizontal rotational movement, improving the positioning accuracy and reducing the hardware wear.

[0035] The above-described embodiments merely represent certain implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
