Problems solved by technology

[0002] Tablet press is a common machine for preparing tablets. It can make medicines quickly and conveniently, facilitate subsequent experiments and measurements, and lay the foundation for the perfect production of medicines; traditional single-punch tablet machines require fine operations in the pharmaceutical process. A little carelessness will cause splits and fragments. At this time, the tablet will appear top crack and waist crack, which will affect the inspection and measurement of the drug; there are many reasons for the split, and one of the common reasons is uneven pressure. During the long-term use of the tablet machine, the pressure rod will be slightly deformed. This deformation is difficult to observe with the naked eye, but it will cause a large pressure difference on the tablet, which will lead to the cracking of the tablet; in addition, the position of the mold is not correct. The force transmission of the pressing rod to the mold is not balanced, and it is easy to cause the tablet to crack

Abstract

The invention relates to a double-shaft medicine tablet pressing machine. The double-shaft medicine tablet pressing machine comprises a base, support arms and driving parts, wherein the support arms and the driving parts are symmetrically arranged at two ends of the base; each driving part comprises a driving motor and a driving rod; the driving rods can screw in and screw out along the self axes under driving of the driving motors; a pressing column is detachably mounted on each driving rod; an acceleration gear set is arranged between each pressing column and each driving rod; an adjusting rod is also arranged on the base; a pressing cylinder is arranged on the adjusting rod; the pressing cylinder is in threaded matching connection with the adjusting rod; the pressing cylinder is coaxial with the pressing columns; a medicine feeding hole is formed in the cylinder wall of one end of the pressing cylinder. The tablet pressing machine is capable of balancing pressure of medicine tablets, uniformly pressing the medicine tablets, reducing the occurrence of tablet cracking phenomenon, saving time and providing convenience for subsequent research.
