Description

Technical Field

[0001] The utility model relates to the technical field of raw material mixing devices, in particular to a raw material mixing device for a capsule production line. Background Art

[0002] The capsule production process typically includes raw material preparation, formula development, mixing, capsule filling, sealing and shaping, quality inspection, packaging, storage, and transportation. The specific implementation details of these steps vary depending on the production scale, drug type, and production equipment. During the mixing process, whether the raw materials are mixed evenly determines the quality of capsule production. Specialized raw material mixing equipment is usually used to achieve uniform mixing.

[0003] The raw material mixing device can evenly mix the raw materials for capsule production, thereby ensuring the quality of capsule production, but it still has certain problems: 1) The mixing effect is achieved by relying on the stirring paddle to push the raw materials to move, and it is unable to drive the raw materials to flip and mix, resulting in low mixing efficiency and quality; 2) Different materials are easily stratified, and the stratification phenomenon cannot be solved; 3) The high-speed stirring process will cause the raw materials to heat up, and some raw materials have temperature requirements; Therefore, in view of the above situation, there is an urgent need to develop a raw material mixing device for a capsule production line to overcome the shortcomings in current practical applications and meet current needs.

Specifically, the stirring paddle is twisted 90 degrees and is divided into two groups, which are respectively installed on the inner and outer ring positions of the stirring frame.

[0008] Preferably, a through hole for feeding is opened on the bottom edge of the inner cylinder, and the outer diameter of the spiral blade is equal to the inner diameter of the inner cylinder. Specifically, the spiral blade cooperates with the inner cylinder to form an auger structure, which transports the bottom raw material upward to avoid stratification of the raw material.

[0024] Example:

[0025] See also Figure 1-Figure 4 The utility model provides a technical solution: a raw material mixing device for a capsule production line, comprising a mixing tank 10, a sealing cover 20 and a motor 30, wherein the sealing cover 20 is detachably connected to the top of the mixing tank 10, and the motor 30 is vertically installed on the top of the sealing cover 20;

[0026] The inner bottom of the mixing tank 10 is recessed to form a collection trough 104, and an inner cylinder 105 is installed in the middle position of the collection trough 104. A rotating shaft 101 is provided inside the inner cylinder 105, and an integrally formed spiral blade 106 is arranged around the lower half of the rotating shaft 101. A stirring frame 102 is nested and installed in the middle position of the rotating shaft 101, and a stirring paddle 103 is installed at the bottom of the stirring frame 102. The top of the rotating shaft 101 is connected to the motor 30 for driving. Specifically, the stirring paddle 103 is twisted at 90 degrees and is divided into two groups, which are respectively installed on the inner and outer ring positions of the stirring frame 102, and the twisting directions of the two groups of stirring paddles 103 are opposite.

[0027] Preferably, an inner flow channel 107 is provided on the side wall of the mixing tank 10, and a liquid inlet interface 108 and a liquid discharge interface 109 are embedded in the outer wall of the mixing tank 10. The liquid inlet interface 108 and the liquid discharge interface 109 are respectively connected to the two ends of the inner flow channel 107. Specifically, the inner flow channel 107 can be used to connect cooling water to realize cooling circulation in the mixing tank 10 to avoid excessive temperature during stirring.

[0028] Preferably, a through hole for feeding is opened at the bottom edge of the inner cylinder 105, and the outer diameter of the spiral blade 106 is equal to the inner diameter of the inner cylinder 105. Specifically, the spiral blade 106 cooperates with the inner cylinder 105 to form an auger structure, which transports the bottom raw material upward to avoid stratification of the raw material.

[0029] Preferably, the inner flow channel 107 is spiral-shaped. Specifically, this structure can extend its cooling path and provide higher cooling efficiency for the internal raw materials.

[0030] Preferably, a vertically arranged positioning shaft 1041 is installed in the middle position of the inner bottom of the aggregate trough 104, and a discharge valve 1042 is installed through the bottom edge of the aggregate trough 104. Specifically, the discharge valve 1042 is used to discharge the mixed raw materials.

[0031] Preferably, a groove is provided at the bottom end of the rotating shaft 101, which is adapted to the positioning shaft 1041, and the rotating shaft 101 is rotatably connected to the positioning shaft 1041. Specifically, the positioning shaft 1041 is provided to cooperate with the groove to ensure the concentricity and stability of the rotating shaft 101 during rotation.

[0032] Working principle: first introduce the raw materials to be mixed into the mixing tank 10, then start the motor 30, and the motor 30 drives the rotating shaft 101 to rotate. During the rotation of the rotating shaft 101, it will drive the stirring frame 102 and the spiral blade 106 to rotate. During the rotation of the stirring frame 102, it will cooperate with the stirring paddle 103 at the bottom to stir and flip the raw materials in the mixing tank 10 to achieve the raw material mixing operation. The spiral blade 106 will cooperate with the inner cylinder 105 to lift the bottom raw materials to the top layer to avoid stratification of the raw materials. It should be noted here that since the stirring paddles 103 installed on the inner and outer rings have opposite twisting directions, their flipping angles for the raw materials are also opposite, which can disrupt the orderliness of the raw material flipping process and make the mixing more uniform.

[0033] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a..." does not exclude the presence of additional identical elements in the process, method, article, or device comprising the element.
