Installation of shape mold for rotary tablet press

Installation of shape mold for rotary tablet press

(1) The installation of the middle die. Unscrew the fastening screws in the die, but die fastening screw head should not be exposed at disc; used in die cleaning knife, remove the dirt in the die hole; remove the overshoot and cover up for handling rail, guide key position, can not rotate, so die and punch shall be installed simultaneously. Put on a punching, die die holes need to set up into the light into the die hole, and then use the stick will die into the above impulse, the guide rod hit the die hole die into 2/3, and then die rod (copper) blow to the position. Then use the upward test to recognize the mold, if normal, it will be installed on the guide plate. The normal die is reinstalled and the middle die end face and the middle turntable worktable 0 ~ -0.05 mm are checked with a knife edge ruler; the tightening die assembly is tightly assembled

(2) Lower punch installation. The lower punch is clean, the right hand holding down into the oiler; punching, press the right hand left hand pressing, push, make hole into the lower punch die inside; adjusting the top column, the flexible movement, but not free fall (all in die after installation, should check again die locking group, to ensure that die fastening normal).  

Punch wear

Punching rod and guide rail are the most frequent parts of the presser, and the effective way to reduce wear is lubrication. Punch rod and guide rail should be checked for lubrication in each class. Lubricate with mechanical oil, add a little each time to prevent pollution. According to the maintenance of SOP oil parts for maintenance, on and down and track these key oil parts, each class to 1 ~ 2 times.  For the materials with astringent, larger varieties should be annual, check up and down activities after work. Clean the die hole and die when it is difficult to move. Roller and bearing should be lubricated regularly.  

Lachung

(1) tablet machine under normal pressure due to the effect of viscosity, make up and down can not move freely in the movement, called lachung (also called hanging red). When the press machine is running, there will be an abnormal sound when it is pulled. When the punch is broken seriously, the track will be broken. Analysis of solutions: 1) to adjust the indoor humidity, relative humidity control in 40% ~ 60%; (2) to adjust the particle viscosity, some accessories for hygroscopic agent or with ethanol granulation; 3) punch and die hole when the gap is too large to replace the die timely, work to clean up the vacuum cleaner in time.   

The electrical part of

(1) a few minutes after boot shutdown: mostly because of pressure, overload protection, pressure should be reduced, restart. (2) not too much oil or oil pump oil pump does not make oil guide rail, punch and other parts are not lubricated, too much oil will pollute the pill, the reason is mostly because the setting problem of the inverter parameters, reset the inverter parameters, adjusting the off time can be. (3) auxiliary power supply is not power: mostly because of line problems, check line solution.

(4) tachometer, counter does not show, button failure, panel failure, axial fan bad, alarm lamp broken, bulb bad, rectifier bridge burned out, etc.. Electrical equipment fault line problems, must check the line, electrical parts damage must be replaced to solve.
