Description

Technical Field

[0001] This utility model relates to the field of planetary mixer technology, and in particular to a planetary mixer with a protective structure. Background Technology

[0002] Planetary mixers are a new type of mixing equipment suitable for various high-viscosity and high-solids materials. Planetary mixers have a unique and novel mixing form. While the agitator revolves around the axis of the vessel, it also rotates at high speed around its own axis at different speeds, causing the material to make complex movements in the vessel and be subjected to strong shearing and mixing. Its efficiency is usually several times that of ordinary mixers.

[0003] The prior art utility model with publication number CN214764941U relates to a planetary mixer, including a mixing assembly. The mixing assembly includes impellers, and a motor for driving the impellers to rotate is connected to a horizontal frame. A vertical frame has a dovetail groove on one side facing the impellers. A dovetail block slides vertically within the dovetail groove of the vertical frame, and a support plate is connected to the dovetail block. A drive mechanism for driving the dovetail block to slide along the dovetail groove is provided on the vertical frame. A clamping mechanism is provided on the support plate. A container is placed on the support plate and clamped by the clamping mechanism. The drive mechanism drives the dovetail block to slide vertically within the dovetail groove, causing the support plate and container to rise or fall, adjusting the position of the impellers within the container, and increasing the contact area between the impellers and the material.

[0004] Because the blades are perpendicular to the table surface and can only rotate laterally, when mixing fine particles or powders, the material inside the container near the blades creates a vortex around the blades due to the centrifugal force generated by the high-speed rotation of the blades. This causes the material on the outside of the container to adhere tightly to the inner wall of the container due to the centrifugal force, thus preventing it from participating in the mixing process. When mixing large particles, the particles at the bottom will remain at the bottom of the container due to gravity, thus preventing them from participating in the mixing process.

[0005] Therefore, it is necessary to provide a new planetary mixer with a protective structure to solve the above-mentioned technical problems. Utility Model Content

[0018] This utility model provides a planetary mixer with a protective structure, which, in specific implementation:

[0019] 1. The rotation of the transmission block drives the large stirring rods on both sides to rotate laterally to stir the material. During stirring, due to the friction between the material and the shovel and sleeve column, the material at the bottom is stirred upward by rotating longitudinally around the large stirring rod. At the same time, the small motor drives the turntable and the small stirring rod at the bottom to rotate through the connecting rod, and the transmission block drives multiple small stirring rods on both sides to revolve around the power box. This device can generate longitudinal stirring by friction while stirring laterally, and the small stirring rods can revolve while rotating, making the stirring effect of the device better and the stirring area more comprehensive.

[0020] 2. When mixing large particles, the protective cover can prevent the material from being squeezed and thrown away at the edge of the mixing tank. At the same time, the first and second keels can enhance the strength of the mixing tank and the protective cover, avoid deformation caused by material impact, and extend their service life.

A mixing mechanism is rotatably mounted inside the mixing tank 1, and a protective mechanism is installed on the surface of the mixing tank 1.

Turntables 9 are rotatably connected to the output ends of the two small motors 7 via connecting rods 8. Small mixing rods 10 are fixedly connected to the lower surface of the two turntables 9. The central part of the two large mixing rods 4 is parallel to the bottom surface of the mixing tank 1, and both ends of the two large mixing rods 4 are bent upwards and downwards respectively. Perpendicular to the bottom surface of the mixing tank 1, two sleeve columns 5 are respectively fitted onto the two large stirring rods 4 at the positions parallel to the bottom surface of the mixing tank 1. The cross-section of the two turntables 9 is "+" shaped, and multiple small stirring rods 10 are wavy. The protective mechanism includes a first keel 11 and a protective cover 12. Multiple first keels 11 are uniformly welded to the inner wall of the mixing tank 1. The protective cover 12 is fixedly connected to the upper end surface of the mixing tank 1.
