China Tablet press force series ZP31 High speed  rotary tablet press machine of Most discount

This machine is a kind of automatic rotating continuous tableting machine. It is suitable for the professional equipment of continuous pressing forming of various granular materials in electronics, food, chemical, daily necessities, pharmaceutical and other industries. The machine is suitable for pressing tablets of larger size, such as milk tablets, calcium tablets, camphor balls and powder metallurgy products. 

Characteristics

1. Double-pressure double-sided film, a large number of die, suitable for large-volume tablet production.

2. The outer casing is fully enclosed and the material is made of stainless steel. The parts in contact with the drug are made of stainless steel or specially treated on the surface, non-toxic and corrosion-resistant, in line with GMP standards.

3. The tableting chamber is closed with transparent plexiglass and can be fully opened for easy internal cleaning and maintenance.

4. Equipped with overload protection device, it can automatically stop when the pressure is overloaded.

5. Mechatronics, using variable frequency stepless speed regulation, easy to operate, safe and reliable.

Technical parameters

The working process of the tablet press can be divided into the following steps:

1. The punch portion of the lower punch (with its working position facing upward) extends from the lower end of the middle die hole into the middle die hole to seal the bottom of the middle die hole;

2. Using a feeder to fill the middle mold hole with the drug;

3. The punching part of the upper punch (the working position is facing downward) falls into the middle die hole from the upper end of the middle die hole, and descends a certain stroke to press the powder into a piece;

4, the upper punch lifts out the hole. The undershoot rises to push the tablet out of the middle die hole to complete a tableting process;

5. Undershoot down to the original position and prepare for the next fill. 

Tablet mechanism principle:

1. Dose control

Various tablets have different dosage requirements, and large dose adjustments are made by selecting dies of different punch diameters. After the size of the die is selected, the slight dose adjustment is made by adjusting the depth of the lower punch into the middle die hole, thereby changing the actual length of the middle die hole after the back cover, to adjust the die hole

The purpose of filling the volume of the drug. Therefore, there should be a mechanism on the tablet press to adjust the original position of the undershoot in the die hole to meet the dose adjustment requirements.

2. Tablet thickness and compaction control

The dose of the drug is determined according to the prescription and pharmacopoeia and cannot be changed. For the storage, storage and disintegration time limits, there is also a requirement for a certain dose of pressure during tableting, which will also affect the actual thickness and appearance of the tablet. Pressure regulation during tableting is essential. This is achieved by adjusting the amount of downstroke in the die hole. Some tablet presses not only have the upper punching down action during the tableting process, but also have the downward action of the undershooting, and the pressing process is completed by the upper and lower punching relative movements. However, the pressure regulation is mostly to achieve pressure regulation and control by adjusting the mechanism of the upper stroke.
