[0022] Please see Figures 1-4In this utility model, a transmission mechanism for a rotational molding machine includes a mounting frame 1. A rotational molding cylinder 2 is provided on one side of the mounting frame 1. A transmission component 3 is connected to the outer surface of the mounting frame 1. The transmission component 3 includes two annular fixing frames 301. A set of sliding blocks 302 are slidably connected to the inner wall of each annular fixing frame 301. One side of the two sets of sliding blocks 302 is connected to the outer surface of the rotational molding cylinder 2. Two annular gear rings 303 are connected to the outer surface of the rotational molding cylinder 2. A power motor 304 is connected to one side of the mounting frame 1. A mounting rod 305 is connected to the output end of the power motor 304. Two gears 306 are connected to the outer surface of the mounting rod 305. By rotating the power motor 304, the mounting rod 305 can be driven to rotate. With the rotation of the mounting rod 305 and the meshing of the gears 306 with the annular gear rings 303, the sliding blocks 302 are slidably connected to the annular fixing frames 301. This allows the annular gear rings 303 to drive the rotational molding cylinder 2 to perform rotational molding, which improves the rotational molding quality of the equipment and reduces the probability of damage.

[0023] Two support frames 6 are connected to one side of the mounting frame 1. Each support frame 6 has two mounting holes on one side. The support frames 6 and mounting holes can be used to support and position the equipment. A bearing seat 4 is connected to one side of the mounting frame 1. The inner ring of the bearing seat 4 is fixedly connected to the outer surface of the mounting rod 305. The bearing seat 4 can increase the rotational stability of the mounting rod 305 and prevent it from swaying. A manual valve body 7 is connected to one side of the rotomolding cylinder 2. The outer surface of the mounting frame 1 is coated with a waterproof layer. The manual valve body 7 can be used to easily inject and discharge material into the rotomolding cylinder 2. In addition, a suitable control valve can be installed as needed.

[0024] A connecting block 8 is connected to the outer surface of the power motor 304. One side of the connecting block 8 is connected to one side of the mounting bracket 1. The connecting block 8 can improve the stability of the power motor 304 and prevent it from becoming loose. A control switch 5 is connected to one side of the mounting bracket 1. Each gear 306 meshes with the ring gear 303. The control switch 5 can be used to conveniently operate and control the operation of the electrical components.

[0025] The working principle of this utility model is as follows:

[0026] First, it is transported to the location of use, and the electrical components are connected to the power supply. The required program is set and controlled by pressing the external control switch 5. At the same time, the material is injected into the rotomolding cylinder 2 through the manual valve body 7. After the material is injected, the power motor 304 starts to work. The rotation of the power motor 304 causes the mounting rod 305 to rotate in the inner ring of the bearing seat 4. The rotation of the mounting rod 305 causes the two gears 306 to rotate as well. The gears 306 mesh with the ring gear ring 303, and the sliding block 302 is slidably connected to the ring fixing frame 301. This allows the rotomolding cylinder 2 to rotate. The rotation of the rotomolding cylinder 2 can process the required items. At the same time, the finished product is discharged using the manual valve body 7. The above is the complete usage process of this utility model.
