Description

Technical Field

[0001] The utility model relates to the field of medicine and chemical industry, in particular to a multi-axis linkage medicine and chemical raw material mixing device. Background Art

[0002] Pharmaceutical chemicals occupy an important position in the national economy of various countries. They are the basic and pillar industries of many countries. The development speed and scale of the chemical industry have a direct impact on various sectors of the social economy. Due to the wide range of pharmaceutical chemicals, complex processes, and diverse products, the pollutants discharged during production are of many types, large quantities, and high toxicity. Therefore, the pharmaceutical chemical industry is a major polluter. At the same time, chemical products may produce a large amount of toxic substances in various links such as processing, storage, use, and waste disposal, which will affect the ecological environment and endanger human health. The sustainable development of the chemical industry has important practical significance for human economic and social development.

[0003] Mixing devices are indispensable in pharmaceutical and chemical production. Generally, mixers are used for pharmaceutical production. A mixer is a machine used to mix materials. It consists of a horizontally rotating container and a rotating vertical stirring blade. When the molding material is stirred, the container turns left and the blade turns right. Due to the effect of countercurrent, the movement directions of the particles of the molding material intersect, and the chances of contact with each other increase. The countercurrent mixer has a small extrusion force on the material, low heat generation, high stirring efficiency, and more uniform mixing. It is characterized by a more uniform and loose mixing, very few dead corners, convenient discharging, easy cleaning, high production efficiency, and equipment that is not easy to wear.

[0004] In the process of realizing the utility model, the inventors found that the prior art had the following problems: 1. When adding materials to the mixing device, the long-term use of the feeding port will cause dust and material dust pollution, which is not only easy to breed bacteria, but also difficult to clean and maintain; 2. Some pharmaceutical and chemical raw materials require uninterrupted stirring operations and raw material addition. If they are left for too long, the pharmaceutical effect will be poor.

[0021] In this embodiment, Figure 1 As shown, the movable seat 7 forms a sliding structure between the pull rod 6 and the pillar 16, and the sliding range is limited by the height of the spring 8; the movable seat 7 can be moved up and down along the pillar 16 through the pull rod 6, and is limited and buffered by the spring 8 when descending, which makes it convenient for operators to operate. At the same time, the filling mechanism has good flexibility and greatly improves the work productivity.

[0022] In this embodiment, Figure 3 As shown, the movable shafts 18 on both sides of the discharge box 19 form a telescopic structure with the interior of the movable seat 7 through the push rod 20, and the internal accommodation size formed by the movable seat 7 and the support frame 5 is larger than the overall size of the discharge box 19; the discharge box 19 can move freely back and forth inside the movable seat 7, and is easy to operate through the push rod 20, and is also easy to store, thereby improving the flexibility and production efficiency of the feeding mechanism.

[0023] In this embodiment, Figure 4 As shown, the motor 1 forms a rotating structure through the transmission shaft 21 and the gears 23, and the gears 23 are equal in size; the motor 1 provides rotational power for the transmission shaft 21, and the gear 23 connected to the transmission shaft 21 drives the other two gears 23, thereby completing the linked rotation of the first rotating shaft 10 and the second rotating shaft 22.

The specific operation process is as follows: raw materials are added through a material box 4, and when adding raw materials, a movable seat 7 can be driven by a pull rod 6 to slide up and down on a support 16, wherein the movable seat 7 is limited and protected by a spring 8 at the bottom of the support 16 to avoid being hit, and a discharge box 1 installed inside the movable seat 7 9 can be flexibly moved through the push rod 20 to avoid splashing onto the discharge box 19 due to overly intense stirring. During stirring, the bottom of the first mixing barrel 13 is supported by a load-bearing frame 12, and the first mixing barrel 13 is higher than the second mixing barrel 15. This design is to enable the raw materials in the first mixing barrel 13 to be drained to the second mixing barrel 15 through the discharge pipe 14 after stirring, so as to complete the transition of short-distance raw materials and avoid waste during transportation.
