Description

Technical Field

[0001] The utility model relates to the technical field of mixing equipment, in particular to a multi-axis linkage square cone mixer. Background Art

[0002] Square-cone mixers are widely used in the pharmaceutical, food, and chemical industries, primarily for mixing powdered or granular materials. They are shaped like a square cone, typically consisting of a square base and a tapered top. Traditional square-cone mixers typically lack a stirring shaft. Instead, they rely on gravity to mix materials through free flow and friction within the conical container. However, during gravity mixing, materials tend to accumulate at the corners and edges of the equipment, forming "dead spots" that prevent adequate mixing. Utility Model Content

[0003] The purpose of this utility model is to address the problem that traditional square cone mixers usually do not have a stirring shaft and their working principle mainly relies on gravity to achieve mixing. However, during the gravity mixing process, materials tend to accumulate at the corners and edges of the equipment, forming "dead spots" and resulting in insufficient mixing of materials in these areas. Therefore, a multi-axis linkage square cone mixer is proposed.

[0004] The technical solution of the utility model is a multi-axis linkage square cone mixer, comprising a mixing drum, and also comprising: a first stirring mechanism arranged in the mixing drum for mixing materials; a second stirring mechanism, arranged at the four corners of the mixing drum and linked to the first stirring mechanism for switching.

[0008] Optionally, the second stirring mechanism further includes a pair of toggle sleeves fixedly mounted on the secondary stirring shaft and corresponding to the stirring rod, the pair of toggle sleeves being arranged at a 90-degree angle when viewed from above, and the outer wall of the toggle sleeve being fixedly connected to the toggle rod that presses against the stirring rod.

[0009] Optionally, the toggle rod is provided with a slot for tightly clamping the corresponding stirring rod.

[0031] Furthermore, the first stirring mechanism includes a base 3 fixedly connected to one end of the mixing barrel 2, and a motor 21 is fixedly connected to the upper surface of the base 3. The output shaft of the motor 21 is movable through the base 3 and is fixedly connected to the main stirring shaft 22. The outer wall of the main stirring shaft 22 is fixedly connected to a plurality of secondary stirring shafts 23 distributed in a circular array, and the inner wall of the base 3 is provided with a sealing mechanism that tightly connects the output shaft of the motor 21 and the base 3.

[0032] Among them, the sealing mechanism includes a sealing card seat 31 fixedly connected to the inside of the base 3 and sleeved with the output shaft of the motor 21. The interior of the sealing card seat 31 is provided with a sealing ring 32 that is tightly sleeved with the output shaft of the motor 21. The inner diameter of the sealing ring 32 is tightly connected to the output shaft of the motor 21. At the same time, the outer diameter of the sealing ring 32 is tightly clamped in the sealing card seat 31, so that no material will leak between the sealing card seat 31 and the output shaft of the motor 21.

[0033] Secondly, the second stirring mechanism includes a plurality of vertical stirring shafts 4 arranged in the mixing drum 2, one end of the vertical stirring shaft 4 being rotatably connected to the inner wall of the mixing drum 2, and a support frame 5 being fixedly connected to the inner wall of the mixing drum 2 for supporting the rotation of the other end of the vertical stirring shaft 4. The internal rotation of the mixing drum 2 is provided with an inclined stirring shaft 6 corresponding to the support frame 5, and the vertical stirring shaft 4 and the inclined stirring shaft 6 are both provided with a plurality of stirring rods 461 arranged in sequence at a 90-degree angle when viewed from above, and the stirring rods 461 being arranged in sequence at a 90-degree angle when viewed from above is to ensure that the materials are stirred evenly. The end of the mixing drum 2 away from the base 3 is internally fixedly connected with a plurality of support rods 8 for supporting the rotation of the inclined stirring shaft 6, and the ends of the vertical stirring shaft 4 and the inclined stirring shaft 6 are both fixedly connected with a rotating protrusion 462, and the ends of the support rod 8 and the support frame 5 are both provided with a card hole 581 for the rotating protrusion 462 to be engaged and rotated.

[0034] Furthermore, the second stirring mechanism also includes a pair of toggle sleeves 7 fixedly mounted on the secondary stirring shaft 23 and corresponding to the stirring rods 461. The pair of toggle sleeves 7 are arranged at a 90-degree angle when viewed from above.

At this time, the motor 21 on the base 3 can be started, and the output shaft of the motor 21 is stuck by the sealing mechanism, so that when the mixing drum 2 rotates and the base 3 faces downward, no material leakage will occur. The output shaft of the motor 21 drives the main stirring shaft 22 to rotate, and the main stirring shaft 22 drives multiple secondary stirring shafts 23 to rotate, so that the materials in the mixing drum 2 are not only mixed by the action of gravity, but also mixed again by the stirring of the main stirring shaft 22 and the secondary stirring shaft 23, thereby making the mixing effect better. Finally, when the secondary stirring shaft 23 rotates with the main stirring shaft 22 as the center, the secondary stirring shaft 23 drives the toggle sleeve 7 thereon to rotate, and the toggle sleeve 7 drives the toggle rod 71 to toggle the stirring rod 461 on the vertical stirring shaft 4 and the inclined stirring shaft 6. As a result, the vertical stirring shaft 4 and the inclined stirring shaft 6 are supported and rotated by the support frame 5 and the support rod 8, thereby stirring the materials in the four corners of the mixing drum 2 which are also dead corners, and then the first stirring mechanism and the second stirring mechanism are started in linkage, and the materials in the mixing drum 2 are fully stirred and mixed, which is fast and efficient.
