Description

Technical Field

[0001] This utility model relates to the field of mixing device technology, specifically a mixing device for capsule production. Background Technology

[0002] In the production process of soft capsules, it is usually necessary to thoroughly mix and stir the contents of the soft capsules. Currently, the stirring method of the mixing tank is mostly a mechanical stirring structure, that is, a motor drives the stirring shaft to rotate, and stirring blades are set on the stirring shaft to achieve the mixing of the mixture. On the one hand, in order to ensure the mixing effect, the structure of the stirring blades usually needs to be specially designed, resulting in a complex stirring structure. On the other hand, since the mixture usually contains insoluble solid particles, this method of mixing by stirring alone makes it easy for solid particles to settle at the bottom of the mixing tank, affecting the final mixing effect. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model provides a mixing device for capsule production.

[0004] The technical solution of this utility model is as follows:

The premixing system is configured to perform coarse mixing of the mixture. The coarsely mixed mixture can be transferred to the fine mixing system via the transfer system, where the fine mixing system performs fine mixing of the mixture. Finally, the mixture is fully mixed through the cooperation of the premixing system and the fine mixing system.

[0006] Firstly, regarding the structure of the premixing system, it includes a premixing cylinder and a first cylinder cover at its upper end. A feeding pipe is provided on one side of the upper part of the premixing cylinder, through which the materials to be mixed can be added into the premixing cylinder. The first cylinder cover is provided with a stirring mechanism that can stir the materials in the premixing cylinder, and the coarse mixing of the mixture can be achieved through the stirring mechanism.

Based on this structure, the fan can deliver airflow between the partition plate and the bottom of the fine mixing cylinder. The airflow is discharged upward through the air holes on the partition plate, causing the mixture to tumble upward, preventing uneven mixing caused by the sedimentation of solid particles. Finally, through the cooperation of the coarse mixing system and the fine mixing system, the mixture is fully mixed. The mixing structure is simple and effectively ensures the uniformity and consistency of the mixture.

[0008] As described above, in order to ensure the fluidity of the mixture in the fine mixing drum and thus ensure the fine mixing effect of the mixture by the aeration mechanism, the air inlet of the blower is connected to a heater through a connecting pipe.

[0009] For ease of heating, the heater is electrically heated.

[0010] Specifically, the heater includes a housing and an internal heating wire. In order to control the temperature of the hot airflow, a temperature sensor is also provided inside the housing.

[0011] In a preferred embodiment, to achieve the recovery and utilization of hot airflow and reduce the heating energy consumption of the heater, the heater is connected to the upper part of the fine mixing cylinder through an air inlet pipe.

[0012] As described above, a mixing device for capsule production includes a pump in terms of the structure of the transfer system. The pump is connected to a premixing cylinder and a fine mixing cylinder via a feed pipe and a discharge pipe, respectively. To improve the uniformity of the mixture entering the fine mixing cylinder, the feed end of the feed pipe extends to the bottom of the premixing cylinder.

[0013] As described above, in order to improve the coarse mixing effect of the premixing system, a number of baffles are provided on the inner circumference of the premixing cylinder in a mixing device for capsule production.

[0014] In a preferred embodiment, to ensure the turbulence effect of the baffle, the axis of the baffle is coplanar with that of the premixing cylinder.

[0015] The beneficial effects of this utility model are as follows: This utility model is a mixing device for capsule production. The materials to be mixed can be added to the premixing cylinder through the feeding pipe, and the mixing mechanism can achieve coarse mixing of the mixture. The coarsely mixed mixture can be introduced into the fine mixing cylinder. The blower can deliver airflow between the partition and the bottom of the fine mixing cylinder. The airflow is discharged upward through the air holes on the partition, which drives the mixture to tumble upward, preventing uneven mixing caused by the sedimentation of solid particles. Finally, through the cooperation of the coarse mixing system and the fine mixing system, the mixture is fully mixed. The mixing structure is simple and effectively ensures the uniformity and consistency of the mixture. Attached Figure Description
