An improved structure of the feeding device of a tablet press

Abstract

The invention relates to an improved structure of a tablet press feeding device. The improved structure comprises a feeding hopper. Fixed blocks are arranged on the outer wall of the feed end of the feeding hopper. Driven blocks are hinged to connection rods II arranged at the upper ends of the fixed blocks through connection rods I arranged at one ends of the driven blocks. Spray nozzles are arranged at the other ends of the driven blocks, the spraying ends of the spray nozzles are matched with the side wall of the feeding hopper, and water inlet pipes are arranged on the spray nozzles. Valves I are arranged on the water inlet pipes, air inlet pipes are connected to the water inlet pipes, and valves II are arranged on the air inlet pipes. Pressurizing valves are arranged at positions, between the air inlet pipes and the spray nozzles, on the water inlet pipes. The valves I, the valves II and the pressurizing valves are controlled by a controller arranged on the outer wall of the feeding hopper. The improved structure has the advantages that the rotatable spray nozzles are connected with the water inlet pipes and the air inlet pipes, so that automatic washing and drying of the inner wall of the feeding hopper are realized, simplicity and convenience in operation are also achieved and troublesome problems in cleaning of the inner wall of the feeding hopper are avoided.

Description

technical field [0001] The invention relates to the field of tablet press feeding devices, in particular to an improved structure of the tablet press feeding device. Background technique [0002] With the rapid development of the pharmaceutical industry, the demand for drugs continues to increase, and various pharmaceutical equipment have emerged as the times require, such as mixers, tablet presses, conveyors, and so on. Tablets are one of the most common dosage forms of medicines, which are tablet-shaped preparations obtained by uniformly mixing medicines and excipients. Because the tablet has the following advantages: first, it is more convenient to transport, store, carry and apply; second, the shape of the product is stable, the dosage is accurate, and the cost and selling price are all low. Therefore, the application range of tablets is becoming more and more extensive, and the research on tablet preparation methods and related equipment is also very necessary. At pre...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide an improved structure of the feeding device of the tablet press to overcome the troublesome problem of cleaning the feeding device of the existing tablet press

The existing feeding device generally adopts a structure in which the inner diameter gradually decreases from the feeding end to the discharging end. When cleaning the feeding device, due to the small diameter of the discharging end of the feeding device, it is not easy to clean, resulting in In the cleaning process, the operation is more troublesome. The initial state of the driven block according to the present invention is parallel to the side wall of the feed hopper, and the driven block can rotate so that the driven block and the lower end of the inner wall of the feed hopper The clip gradually increases, and the maximum angle is 90°. The rotation of the driven block drives the rotation of the nozzle. The cleaning process of the feeding hopper is as follows: firstly, the controller controls the opening of the valve I and the pressure valve, and the cleaning water is pressurized by the Spray from the nozzle to clean the side wall of the feed hopper. During the cleaning process, the driven block is rotated to change the angle between the nozzle and the inner wall of the feed hopper, and to clean different parts of the inner wall of the feed hopper. , the controller closes and opens the valve I, and opens the valve II so that the air is sprayed out from the nozzle to dry the inner wall of the feeding hopper to keep the inner wall of the feeding hopper dry and clean. The invention automatically cleans the inner wall of the feeding hopper and is easy to operate. Convenient, in this way, the present invention overcomes the relatively cumbersome problem of cleaning the feeding device of the existing tablet press
