Problems that need to be paid attention to when the tablet press is used
The common faults of the mechanical parts of the tablet press are: guide rail, press wheel, punch press, die and other parts; The most common problems in the production process are sound anomalies and sheet weight differences, which involve many factors, including improper use and supervision. When using the press machine, the press room should be cleaned regularly and the working parts that are easy to wear should be checked regularly.
Pay attention to the method of refueling during operation. Clean the remaining oil on the punch surface with a cloth, add some oil with a small brush, and then evenly apply it to the punch cap. However, the amount of oil should not be too much, so as not to cause oil powder into oil. Refuel at least twice per shift.
Poor oil quality, guide rail and connecting rod lubrication only oil lubrication. You have a choice of 30 gear oil or air compressor oil.
Molding press is very fine, there is a lot of dust, feeding needs to be light, in order to prevent dust flying, so that the upper punching and hanging erosion and even wear on the guide rail.
Press sheet material stamping wet, according to this phenomenon caused splicing products suspension or wear guide deformation, and the material drying treatment, in addition, the process should be strengthened to control the material particle size distribution, liquidity and compressibility.
The upper punching hole is not clean, resulting in the upper punching suspension punching, adhesive punching and upper guide rail wear. Clean up the punch hole so that the overhand punch hole can slide freely.
Lower guide wear: Lower guide wear across bridge deck. It can be repaired with oil in light cases and replaced only in severe cases.
If the press is too fine or too wet, it will lead to the down punching or the skin of the down punch, which will lead to the wear of the down punch, viscous punch and the down guide rail. Is there any abnormal sound during the operation of the tablet press? In case of abnormal sound, the machine should be stopped for processing in time, and the holes, knots or indentation on the punching shall be cleaned for reprocessing. Prevent serious leakage and damage to bottom guide rail. The underpunch is not clean, which leads to the phenomenon of underpunch hanging. Flush with a clean brush and remove with a scraper. Especially for thicker products, alcohol should be used in the cleaning process to ensure the flexible rotation of the punch.
