Description

Technical Field

[0001] This utility model belongs to the field of solid dosage form production equipment, specifically relating to a mixer for the production of rheumatic and bone pain preparations. Background Technology

[0002] Rheumatoid arthritis preparations include tablets and capsules, containing various traditional Chinese medicine ingredients. The preparation process requires grinding these herbs into powder and then mixing them, necessitating the use of a mixer. A mixer consists of a horizontal container and rotating vertical stirring blades. During mixing, workers add two or more solid particles to the container; the relative movement of the blades and container causes the materials to come into contact and move within the container, ultimately mixing them together. In a rotary mixer, workers manually add solid particles to the container before starting the mixer to mix them. While this method also achieves mixing, the vertical accumulation of powder particles makes it difficult for the mixer to achieve uniform mixing in that direction, leading to low production efficiency, affecting the efficacy of subsequent preparations, and resulting in a more complex structure and higher manufacturing costs.

[0003] In view of this, in order to solve the above problems, this utility model proposes a mixer that achieves mixing of materials by combining two staggered stirring mechanisms with a driving mechanism that drives the mixing drum to rotate, thereby achieving uniform mixing of materials, reducing mixing time and improving production efficiency. The mixer has a simple and reasonable structural design, low cost and strong practicality. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] See Figure 1-4 A mixer for producing rheumatic and bone pain preparations includes two symmetrically arranged support frames 1 and a double-cone mixing cylinder 2. The mixing cylinder 2 is rotatably connected to the two support frames 1 via rotating shafts 10 on both sides. The rotating shafts 10 are fixedly connected to the mixing cylinder 2 and rotatably connected to the support frames 1. The mixing cylinder 2 is driven to rotate by a drive mechanism 3 mounted on the support frames 1. A first stirring mechanism 4 is provided inside the mixing cylinder 2 along its axial direction.

A feed port 7 is opened on one side of the mixing cylinder 2, and a sealing cover 8 is detachably provided on the feed port 7. A second stirring mechanism 9 is provided on the side of the mixing cylinder 2 opposite to the feed port 7. The first stirring mechanism 4, the second stirring mechanism 9, the drive mechanism 3, and the electrically controlled valve 6 are electrically connected to a controller via signal lines.

[0016] The preferred first stirring mechanism 4 includes a first motor 401, a first stirring shaft 402, a first stirring rod 403, and a fixing frame 404. The first motor 401 is located on the end of the mixing cylinder 2 away from the feed inlet 7. The fixing frame 404 is located inside the mixing cylinder 2 on one side of the feed inlet 7. The first stirring shaft 402 is fixedly connected to the output shaft of the first motor 401 and passes through the end of the mixing cylinder 2 and is rotatably connected to the fixing frame 404. The two ends of the first stirring shaft 402 inside the mixing cylinder 2 are respectively horizontally connected to fixing rods 405. The first stirring rods 403 are respectively fixedly connected to the fixing rods 405 on both sides, and the first stirring rods 403 are adapted to the conical structure of the mixing cylinder 2. The first motor 401 is electrically connected to the controller through a signal line. When in use, the controller starts the first motor 401, which drives the first stirring shaft 402 to rotate, thereby driving the first stirring rods 403 on both sides to rotate along the conical interior of the mixing cylinder 2 to stir and mix the materials.

[0017] Preferably, connecting rods 406 are fixedly connected to both sides of the middle of the first stirring shaft 402, and second stirring rods 407 are horizontally connected to the two connecting rods 406 respectively. The second stirring rods 407 and the first stirring rods 403 are staggered, which can enhance the contact and collision of the mixed materials to reduce the mixing time.

[0018] The preferred design features connecting rods 406 on both sides of the first stirring shaft 402 with different lengths, which can enhance the contact and collision of the mixed materials to reduce mixing time.

[0019] The preferred second stirring mechanism 9 includes a second motor 901, a second stirring shaft 902, and L-shaped stirring rods 903. The second motor 901 is fixed to the outer surface of the mixing cylinder 2. The second stirring shaft 902 is fixed to the output shaft of the second motor 901 and passes through the mixing cylinder 2. The free end of the second stirring shaft 902 is vertically located on one side of the long connecting rod 406. Multiple L-shaped stirring rods 903 are fixed at intervals on both sides of the second stirring shaft 902. The second motor 901 is electrically connected to the controller through a signal line. In use, the controller starts the second motor 901, which drives the second stirring shaft 902 to rotate, thereby driving the multiple L-shaped stirring rods 903 to rotate, which can enhance the contact and collision of the mixed materials and reduce the mixing time.

[0020] The preferred two support frames 1 are each detachably provided with bearing seats 11, and the rotating shafts 10 on both sides of the mixing cylinder 2 are respectively connected to the shafts of the bearing seats 11.

[0021] The preferred drive mechanism 3 includes a drive motor 301, two pulleys 302 and an annular belt 303. The drive motor 301 is fixedly connected to a support frame 1. The two pulleys 302 are respectively sleeved on the drive motor 301 and the rotating shaft 10 on the same side. The two pulleys 302 are connected by the annular belt 303. The drive motor 301 is electrically connected to the controller through a signal line. In use, the drive motor 301 is started by controlling it to drive the pulleys 302 to rotate, thereby driving the mixing drum 2 to rotate.

[0022] The working principle of this utility model is as follows: First, open the sealing cover 8, put the mixture into the mixing cylinder 2, and lock the sealing cover 8. Then, simultaneously start the first motor 401, the second motor 901, and the drive motor 301. At this time, the first motor 401 drives the first stirring shaft 402 to rotate, thereby driving the first stirring rods 403 on both sides to rotate along the conical interior of the mixing cylinder 2. The second motor 901 drives the second stirring shaft 902 to rotate, thereby driving the multiple L-shaped stirring rods 903 to rotate and driving the second stirring rods 407 on both sides of the middle of the second stirring shaft to rotate. The drive motor 301... The belt pulley 302 is driven to rotate, which in turn drives the mixing drum 2 to rotate. The first stirring rod 403, the second stirring rod 407 and the L-shaped stirring rod 903 on both sides cooperate to increase the contact area and contact frequency of the mixture during the rotation of the mixing drum 2. This reduces the mixing time, makes the mixture more uniform, improves the efficacy of the preparation, and thus improves production efficiency. After the material is mixed, the drive motor 301 is controlled to drive the mixing drum 2 so that the discharge port 5 is vertically downward and the electric valve 6 is controlled to open so that the mixture is discharged from the discharge port 5.
