Description
A drive frame for a rotary mixing tank Technical Field
[0001] This utility model relates to the field of rotary mixer technology, specifically a drive frame for a rotary mixing tank. Background Technology
[0002] After adding plastic additives or fillers to the main plastic material, the two need to be mixed evenly to ensure consistent quality and performance of the injection-molded products. Currently, rotary mixers are required for mixing plastic granules. A rotary mixer is a mechanical device used for mixing, stirring, or homogenizing materials, widely used in food processing, chemical, pharmaceutical, and construction industries. Its working principle involves rotating blades or paddles that cause the materials to flow, shear, or tumble within the container, thereby achieving uniform mixing or reaction.
[0003] Existing rotary mixers typically achieve mixing by rotating a mixing drum around a fixed frame on a single axis. However, this mixing method relies solely on the rotation of a single axis, and the materials mainly rely on gravity to fall freely for mixing, resulting in limited mixing effect. Since the mixing depends on the rotation of the drum on a single axis, it takes a long time to achieve the ideal uniformity, which affects production efficiency. Summary of the Invention

However, this mixing method relies on the rotation of a single axis, and the materials mainly rely on gravity to fall freely for mixing, resulting in limited mixing effect. Since the mixing depends on the rotation of the tank on a single axis, it takes a long time to achieve the ideal uniformity, which affects production efficiency.

A drive unit for rotating the rotating frame is located at the bottom of the support frame. The stirring drum is engaged with the support frame. The rotating frame rotates inside the support frame to drive the stirring drum to rotate inside the rotating frame.
[0007] By adopting the above technical solution, the material can be mixed at multiple angles within the mixing drum through the combined motion of the rotating frame's revolution and the mixing drum's rotation, thereby improving mixing uniformity and efficiency.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Example 1
[0032] Please refer to Figures 1, 2, and 3. This embodiment provides a technical solution: a drive frame for a rotary mixing tank, including a support frame 1 and a mixing unit 2.
[0033] The stirring unit 2 is located on the top of the support frame 1. The stirring unit 2 has a rotating frame 202 rotatably mounted on the top of the support frame 1. A stirring drum 201 is rotatably mounted inside the rotating frame 202. The top of the stirring drum 201 has an inlet and the bottom of the stirring drum 201 has an outlet. Valves for controlling the opening and closing of the inlet and outlet are provided. Resistance blades are provided inside the stirring drum 201 to improve the efficiency of stirring and mixing. The above is the prior art and will not be described in detail below.
[0034] The rotation axis of the mixing drum 201 is perpendicular to the rotation axis of the rotating frame 202. The bottom of the support frame 1 is provided with a drive unit for driving the rotating frame 202 to rotate. The mixing drum 201 is meshed with the support frame 1. The rotating frame 202 rotates inside the support frame 1 to drive the mixing drum 201 to rotate inside the rotating frame 202. Through the combined motion of the revolution of the rotating frame 202 and the rotation of the mixing drum 201, the material can be mixed at multiple angles in the mixing drum 201, thereby improving the uniformity and efficiency of mixing.
[0035] Example 2
[0036] Please refer to Figures 4, 5, and 6. This embodiment provides a technical solution: a drive frame for a rotary mixing tank, including a support frame 1, a mixing section 2, bevel gear a102, and bevel gear b206.
[0037] A rotating groove 101 is provided horizontally on the top of the support frame 1. The rotating frame 202 is horizontally embedded in the rotating groove 101 and rotatably connected to the support frame 1. The rotating groove 101 can limit the rotation of the rotating frame 202, ensuring that the rotating frame 202 rotates stably only along the horizontal axis, avoiding skewness or jamming.
[0038] A transmission wheel 203 is fixedly installed on the side of the rotating frame 202. The fixing method is an existing detachable fixing, such as bolt connection, snap connection, etc. A motor 204 is installed at the bottom of the support frame 1. A transmission belt 205 is installed on the surface of the transmission wheel 203. The transmission belt 205 is also connected to the output end of the motor 204. The working principle of the motor 204 is based on electromagnetic induction and Lorentz force. The motor 204 generates force in the magnetic field through current, thereby driving mechanical movement. The above is the existing technology and will not be described in detail below. When selecting the model, its power should be selected to match the needs of the device to ensure that the object to be driven is driven. The transmission belt 205 driven by the motor 204 can drive the transmission wheel 203 to rotate, thereby efficiently transmitting power to the rotating frame 202.
[0039] A conical tooth b206 is fixedly installed on the side of the mixing drum 201. The fixing method is an existing detachable fixing, such as bolt connection, snap connection, etc. A conical tooth a102 is installed on the top of the support frame 1. The conical tooth a102 is meshed with the conical tooth b206. Through the meshing of the conical tooth a102 and the conical tooth b206, the horizontal rotation of the rotating frame 202 is converted into the vertical rotation of the mixing drum 201, realizing orthogonal transmission.
[0040] The included angle between bevel tooth a102 and bevel tooth b206 is 90°. The number of teeth of bevel tooth b206 is greater than the number of teeth of bevel tooth a102. The accuracy of motion direction conversion can be ensured through 90° orthogonal transmission. At the same time, the difference in the number of teeth is used to achieve deceleration and torque increase, thereby enhancing the torque output of the stirring drum 201.
[0041] The stirring part 2 also has a groove 208 formed on the side of the stirring drum 201. The rotating frame 202 is embedded in the groove 208 and rotatably connected to the stirring drum 201. The axial displacement of the stirring drum 201 can be restricted by the fitting structure of the groove 208 and the rotating frame 202, while allowing it to rotate freely around its own axis.
[0042] Inside the rotating frame 202, a roller 207 is rotatably arranged. The roller 207 abuts against the outer wall of the stirring drum 201. The rolling support of the roller 207 can reduce the frictional resistance when the stirring drum 201 rotates, reduce energy consumption and extend the service life of the components.
[0043] There are six rollers 207, which are arranged in a central rotational symmetric structure around the rotation axis of the stirring drum 201. The load of the stirring drum 201 can be evenly distributed by the six symmetrically distributed rollers 207, ensuring rotational balance and stability.
[0044] Working principle: First, power on the device. Then, pour the materials to be mixed into the mixing drum 201. Next, start the motor 204. The motor 204 drives the transmission wheel 203 to rotate via the transmission belt 205, which in turn drives the rotating frame 202 to revolve around a horizontal axis. Since the rotating frame 202 is embedded in the rotating groove 101 of the support frame 1, its movement is restricted to a stable horizontal rotation. At the same time, the rotation of the rotating frame 202 drives the mixing drum 201, which is fixed inside it, to revolve as a whole. Because the side of the mixing drum 201 is provided with bevel teeth b206, which mesh with the bevel teeth a102 on the top of the support frame 1, the rotation... The rotation of the rotating frame 202 is converted into the rotation of the mixing drum 201 around its vertical axis via a bevel gear transmission. The number of teeth on bevel gear b206 is greater than that on bevel gear a102, causing the rotational speed of the mixing drum 201 to be lower than the revolution speed of the rotating frame 202. This achieves deceleration and torque increase, enhancing the mixing torque. Through the combined rotation and revolution of the mixing drum 201, the internal materials are continuously tumbled, sheared, and mixed under the action of centrifugal force and gravity. The resistance blades on the inner wall of the mixing drum 201 further increase the turbulence effect of the material flow, improving the mixing uniformity. After mixing, the mixture is discharged through the outlet at the bottom of the mixing drum 201. Throughout the process, the coordinated movement of the rotating frame 202 and the mixing drum 201 achieves a highly efficient and uniform mixing effect.
