Description

Technical Field

[0001] This utility model relates to a vacuum feeding machine for the general mixing process of traditional Chinese medicine preparations, belonging to the field of pharmaceutical equipment technology. Background Technology

[0002] A vacuum conveyor is a device that uses a vacuum pump to create a vacuum for conveying powdered or granular materials; it is a type of pneumatic conveying. In the field of traditional Chinese medicine (TCM) pharmaceuticals, the final mixing process is a crucial step in the final mixing of multiple batches of extracts, excipients, and other intermediates. The vacuum conveyor, as a material transfer device, is a core piece of equipment in the final mixing process of TCM preparations. However, existing technologies suffer from the following bottlenecks: the feed hoppers of current vacuum conveyors lack height adjustment capabilities. In the final mixing process of TCM pharmaceuticals, the vacuum conveyor needs to transfer intermediates from the temporary storage area to the final mixing equipment. The fixed-height feed hopper design leads to serious compatibility issues in practical applications.

[0003] The inlet height of different models of mixers varies from 0.8m to 2.5m, while the outlet of the inlet of traditional vacuum feeders is at a fixed height. Existing technologies often use raised bases or flexible hoses for transition. However, using stainless steel supports to raise the equipment disrupts the flatness of the workshop floor, creating cleaning dead zones; lengthening the corrugated hose connection leads to increased material residue and makes the bends in the hose prone to microbial growth. Therefore, we propose a vacuum feeder for the total mixing process of traditional Chinese medicine preparations to solve the serious compatibility problem caused by the fixed height of vacuum feeders. Utility Model Content

[0004] The purpose of this utility model is to provide a vacuum feeding machine for the total mixing process of traditional Chinese medicine preparations, which adopts an automatically adjustable feeding hopper to adapt to mixers of different heights, thus solving the serious compatibility problem caused by the fixed height of the vacuum feeding machine.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: a vacuum feeding machine for the total mixing process of traditional Chinese medicine preparations, including a base, a column on the base, a sliding part that can slide up and down installed on the side wall of the column, a connecting plate on one end of the sliding part away from the column, and a vacuum hopper on the other end of the connecting plate, so that the sliding part can drive the vacuum hopper to slide up and down, a vacuum pump installed on the base, and the air extraction port of the vacuum hopper connected to the vacuum pump; The connecting plate has a through threaded hole in the middle. The top of the column is equipped with a mounting bracket. A rotatable threaded column is vertically arranged between the mounting bracket and the base. The threaded column passes through the threaded hole and engages with it. The mounting bracket is fixedly equipped with a drive motor. The drive motor is driven to the top of the threaded column. The drive motor can drive the threaded column to rotate. When the threaded column rotates, the connecting plate can move up and down through the threaded hole. The lifting and lowering of the vacuum hopper can be controlled by controlling the forward and reverse rotation of the drive motor.

[0006] The aforementioned vacuum feeding machine for the general mixing process of traditional Chinese medicine preparations includes a sliding part comprising a support plate.
