Automatic lift type drug pressing device

Abstract

The invention discloses an automatic lift type drug pressing device which comprises a pressing machine and a drug pressing die, wherein the pressing machine comprises an upper pressing block and a lower pressing block; the drug pressing die is arranged between the upper pressing block and the lower pressing block; a mechanical arm enabling the drug pressing die to move along the upper pressing block is connected between the upper pressing block and the drug pressing die; the upper end of the mechanical arm is fixedly connected with the upper pressing block; a slide is arranged on the mechanical arm along the vertical direction; the upper end of the slide is close to the bottom surface of the upper pressing block, and the lower end of the slide is close to the lower end of the mechanical arm; a support lug capable of moving along the slide is arranged at the lower end of the slide, and the support lug is fixedly connected with a die sleeve of the drug pressing die; and the length of the slide is greater than or equal to the height of an upper cushion block of the drug pressing die and less than or equal to the sum of the stroke of the upper pressing block and the height of a die retreating seat of the drug pressing die. According to the device disclosed by the invention, the labor cost is saved, and the reliability of safe production is improved.

Description

technical field [0001] The invention relates to a medicine pressing device, in particular to an automatic lifting medicine pressing device. Background technique [0002] In the prior art, the large-equivalent drug pressing device is composed of a press and a drug pressing mold. When making a large-scale drug column, it is necessary to use a press to bidirectionally press the drug column in the drug pressing mold. During this process, the drug pressing mold needs to be lifted several times. like Figure 1 to Figure 6 As shown, the steps of pressing large-scale grains are as follows: [0003] Step 1: If figure 1 As shown, the drug pressing mold 3 is assembled and placed between the upper briquetting block 1 and the lower briquetting block 2 of the press. At this time, the drug pressing mold 3 does not contain the ejector seat 3.3, and the base 3.6 is located on the lower briquetting block 2; The upper pressing block 1 moves downward, and presses the punch 3.4 into the bore...

AI Technical Summary

Problems solved by technology

However, in general, piston columns are arranged around the press, and the medicine pressing mold 3 is located at the center of the press. It is difficult to move the medicine pressing mold 3 from the center of the press where the space is relatively narrow, and it is difficult to carry out multiple lifts.

What's more, the large-equivalent pressing mold often weighs more than 50 kilograms, and the lifting of the pressing mold 3 is often done manually, which not only consumes a lot of manpower, but also seriously affects work efficiency, and there are potential safety hazards
