Introduction to Lubrication and Maintenance of Tablet Press
The tablet press has excellent performance, strong adaptability, convenient use, convenient maintenance, small size, light weight, and can be shaken even when there is no electricity. This machine only installs the mold, the filling depth of the material, and the thickness of the tablet can be adjusted, which can adapt to the requirements of the pharmaceutical industry, suppressing various similar products in various Chinese and Western medicine preparations and other industries, and is widely accepted by users in all walks of life. welcome.
Lubrication and maintenance of tablet presses:
1. The lubrication of the friction surfaces of all moving parts is an important link to ensure the normal operation of the machine and prolong the service life. In particular, if the main moving parts are dry and run without oil, they will quickly be damaged and cannot be used. Therefore, before the tablet press is used, all oil cups, oil holes and friction surfaces must be lubricated, and the air is running, so that each friction surface is covered with an oil film before use. In the future, every shift will be refueled on time, but each refueling should not be too much, so as not to overflow, affect the cleanliness and contaminate the tablets.
2. Before each work, check whether the screws of the tablet press are loose. During work, be sure to check the machine. If it is loose, please tighten it immediately to avoid malfunction. The main components are: upper punch fastening nut, intermediate mold fixing screw, lower punch positioning screw; connecting rod locking nut, connecting rod pin fixing screw; lifting fork locking nut (2) butterfly screw; installation fixing screw (2 ).
3. Before and after each shift, several pieces must be manually tested, and then there is no problem after turning on the electric tablet.
4. During the tableting process, the quality of the mold should be checked frequently. If the edge is missing, cracked or severely damaged, it should be replaced in time to avoid damage to the machine and affect the quality of the tablet.
5. After daily use, take out the remaining powder and wipe off all parts of the machine. If the downtime is long, the mold must be removed and the tablet pressed against each surface. Wipe the work surface, apply anti-rust oil, and cover with dust-proof clothing; the mold should be wiped clean and soaked in oil to save.
6. Check the machine regularly, 2 times a month.
The reason for the adhesion of the tablet press: the adhesion is that the fine powder on the surface of the tablet is adhered by the punch and the die when the tablet is pressed, so that the surface of the sheet is not only uneven, but the surface is uneven and has dents, and the lettering punch is easier stuck.
1. The surface of the tablet press punch is damaged or the surface finish is reduced. There may also be anti-rust oil or lubricating oil, the surface of the new mold is rough or the lettering is too deep and angular. The punch can be wiped clean and replaced with a substandard mold, or rubbed with a small amount of liquid paraffin on the surface of the lettering punch to lubricate the surface. Also, if the sticking is caused by mechanical heating, check the cause and repair the device.
2. The engraving and punching character design is unreasonable. Replace the hole punch or change the character design accordingly.
3. The water content of the granules is too much or the granules are not dry and moist, resulting in adhesion. Solution: Control the moisture content of granules within the range of 2%~3%, and strengthen the inspection of dry food.
4. The amount of lubricant used is insufficient or improperly selected, and there are too many fine powders. Appropriately increase the amount of lubricant or replace with new lubricant to remove excess fine powder.
5. The fineness of the original excipients varies greatly, resulting in uneven mixing or inappropriate mixing time. Solution: crush and sieve the raw and auxiliary materials to make the fineness meet the variety requirements. At the same time, master and control the mixing time of the tablet press.
