Brief introduction to the main structure and operation of tablet press

Tablet press is mainly used for tablet technology research in pharmaceutical industry It is an automatic continuous production equipment for pressing granules into circular and irregular shape with diameter no more than 13mm and with characters, symbols and figures The punch and die of the tablet press are under great pressure in the process of tablet pressing Bearing steel is usually made and heat treated to improve its hardness There are many types of punches The shape of the punches depends on the shape of the tablets According to the structural shape of the die, it can be divided into round and special shape; the shape of the die section includes plane shape, hypotenuse shape, shallow concave shape, deep concave shape and comprehensive shape Flat and beveled punches are used to press flat cylindrical tablets, shallow concave punches are used to press biconvex tablets, deep concave punches are mainly used to press coated tablets, and comprehensive punches are mainly used to press irregular tablets In order to identify and take medicine easily, drug name, dosage and vertical and horizontal lines can also be engraved on the end face of the die In order to suppress different doses of tablets, the appropriate die size should be selected In addition, the punch up bar of the rotary table of the tablet press has requirements on the structure of the tablet press The requirements are raised on the die because the punch up bar needs to be provided with a directional key, which is coordinated with the punch up bar of the rotary table during the installation process The lower punching rod does not leave the middle die hole in the working process, and does not need other processing It is not able to rotate freely to press tablet punching rod with special-shaped die Instead, it moves up and down the upper and lower guide rails When driven by the turntable, the punching rod and guide rails are subject to sliding friction, so that the punching rod and guide rails are worn each other During the use of the tablet press, it is necessary to check the parts regularly, once or twice a month The inspection items are whether the worm gear, worm, bearing, pressing wheel, crankshaft, upper and lower rail guide and other moving parts rotate flexibly and wear If any defect is found, it shall be repaired and used in time After one-time use or shutdown, take out the residual powder and brush the residual powder of all parts of the machine If the machine is out of service for a long time, all the dies must be removed, and all the machines must be wiped and cleaned The smooth surface of the parts must be coated with antirust oil and covered with a cloth for the next use The maintenance of the die should be placed in a special box, so that the die can be completely penetrated into the oil, and it should be kept clean, so as not to rust and bruise Zui can customize the special box to be packed in one box with each specification, so as to avoid the wrong installation and help to master the damage The place of use should be cleaned frequently, especially for the manufacture of medicine and edible tablets Electrical components shall pay attention to the working environment conditions, such as temperature, humidity, etc., which will extend the service life of components in a good environment Pay attention to regular maintenance and inspection, and keep in good operation condition The cooling fan shall be regularly cleaned of dust by compressed air The maintenance of electrical components shall be carried out by professional technicians, especially the frequency converter Generally, it shall be sent to a professional manufacturer for maintenance, and it is not allowed to disassemble and assemble by itself.
