[0002] When the medicine factory is making tablets, it needs to pass through the tablet press to get the fixed shape tablets. The sticking and sticking is one of the common problems in the tabletting process. When the powder particles stick to the punch surface and cannot form a smooth surface, it is called sticking and sticking.

[0003] The role of lubricant is to prevent powder from sticking to the die, the middle die and other metal materials during tabletting, and can also promote the tabletting. The lubricant is not a liquid or oil, but a light fine powder. Generally, the proportion of lubricant in the prescription is relatively low, and the amount is between 0.25% and 2%. The common lubricant in the drug prescription is magnesium stearate. Although the amount of lubricant is relatively low, it can greatly affect the tabletting performance. If the mixing method is not correct, the lubricant may not work correctly. During the lubricating step, the problem of uneven mixing of lubricant often occurs. The lubricant must be in contact with the metal to achieve good lubrication effect. If the lubricant is not added, the powder will make a kuku sound during tabletting, and the tabletting force will also increase, which will cause damage to the die and the ejection cam. Not adding lubricant or using too little lubricant will cause sticking and sticking or middle die sticking.

[0004] The lower cover of the forced discharger of the prior art tablet press is shown in Figure 1 The raw material discharging cavity 31 and the raw material discharging cavity 32 of the material disc lower cover 3 are used for filling the powder, and the magnesium stearate powder injection pipe 33 is arranged at the front end of the raw material discharging cavity 31, as shown in Figure 2 The magnesium stearate powder injection pipe 33 sprays the lubricant on the upper punch surface and the lower punch surface, which can only solve the problem of sticking and sticking of the upper and lower punches, and cannot spray the lubricant into the middle die, so the effect is not obvious, and the middle die is still stuck.
