tablet pressThere are some problems in the process of using. After the problem occurs, it must be carefully checked to find out the fault and cause of the tablet press and deal with it in time. Here are some examples of common failures of accurate maintenance of tablet presses:

1. Unable to boot

First check the protection devices, such as lubrication protection, pressure overload protection, main motor overload protection, feeding motor overload protection, and eliminate them one by one.

2. tablet press guides

The guide rail is an important part to ensure the movement of the punch along the curved track. Common faults include: rail wear, loose parts, wear of lower rail bridge plate, and wear of rail body caused by punch.

The way to solve the wear of the middle rod and the guide rail is to grind the guide rail flat with an oil stone to restore it to normal. If the wear is serious, only the guide rail can be replaced. The lower rail bridge plate is worn, the lighter one needs to be repaired with oil stone, and the severely worn one can only be replaced.

3.tablet pressMold

The die is an important part of the tablet press. Common faults in use: moderate wear. After the punch is worn, a new middle rod needs to be replaced. The bending of the punch occurs mostly on the small diameter punch, which is mainly caused by excessive pressure. The bending of the punch will affect the weight difference of the tablet and needs to be replaced.

4. roller

The pressure roller is a device that adjusts the pressure of the tablet and increases the protection. Common failures include roller wear, lack of oil, or damage to the roller bearing.

The outer ring of the pressure roller is severely worn, resulting in high resistance at the end of the punch, and the pressure roller needs to be replaced; when the inner hole of the pressure roller and the pressure roller shaft are severely worn, the pressure roller or the pressure roller shaft needs to be replaced: the pressure roller shaft sometimes breaks, mainly The pressure is too large, and most materials are difficult to press because of improper adjustment. At this time, it is necessary to replace the roller, adjust the material and readjust the pressure.

5. overload protection

The common fault of overload protection system is frequent alarm. The main reason is that the sheet pressure is too large or the set pressure of the overload protection spring is too small.

The solution is to adjust the pressure handwheel, reduce the pressure of the overload protection spring or increase the set pressure.

6. gearbox

The reduction gearbox is composed of a worm wheel, a worm and a box body. A common fault is an oil leak in the gearbox. Mainly caused by screw loosening or oil seal aging.

The solution is to tighten the screws or replace the oil seal and apply sealant.

7. Other

1, the timing belt is too tight or too loose, appropriate adjustment can be;

2, the motor and mechanical transmission part of the phase resonance, should avoid the speed of the vibration section;

3. Long-term use will cause large gaps in the transmission part and loose parts. Adjust the gap and tighten the parts;

4, too many particles, powder viscosity, causing blockage, adjust the particles to solve;

5, the shaft and bearing lack of oil wear, should be regularly checked and replaced;

6, the main worm gear box lack of oil, wear, noise, should be replaced regularly;

7. Double pressuretablet pressThe pressure on both sides is unbalanced and the adjustment is consistent.
