There are many factors that contribute to the occurrence of chip weight deviation, and users need to carefully observe and handle it in a timely manner.

Our company's GZPTS dual discharge tablet press has unique advantages in tablet weight control.

1. Different from traditional tablet presses in terms of transmission mechanism. The GZPTS dual discharge tablet press adopts a precision screw inclined lifting mechanism. No return trip; High control accuracy. The traditional tablet press uses a worm gear mechanism. The return volume is relatively large; Low control accuracy.

2. In terms of controlling the number of punches, it will be more than three times higher than traditional tablet presses.

3. The forced feeder adopts a three-blade layer by layer feeding method to reduce the impact of material weight on the sheet weight.

Below are the factors and treatment methods that cause weight differences in the GZPTS dual discharge tablet press, hoping to serve as a reference in production.

1. Length of the punch:

The length of the punch directly affects the weight of the piece. When there is a difference of ± 0.03mm in the length of the punch, the punch that exceeds the tolerance must be removed.

During use, the working pressure of the user must be controlled within the allowable working pressure of the punch (specific requirements can be found in the product manual), especially for punches with a diameter less than 7mm. Furthermore, if the machine is shut down for a long time, it must be depressurized and unloaded.

2. Inconsistent particles:

Uneven particles will also affect the weight of the sheet. More coarse particles result in lighter flakes, while more fine particles result in heavier flakes. In this situation, the mixing method should be improved by increasing the batch quantity as much as possible to reduce batch differences.

3. Overhead feeding frame:

The phenomenon of overhead is mainly caused by poor fluidity of materials. The fluidity of materials should be changed. The GZPTS dual discharge tablet press can be improved by adding a vibration motor according to specific situations.

4. Downward damping pin failure:

The damping pin of GZPTS dual discharge tablet press adopts permanent magnet damping pin. In case of failure, it must be replaced in a timely manner.

5. Dirt under the weight adjustment inclined plate

Timely cleaning is a task that every user unit must accomplish. The general rule is that the small cleaning session is for each class, and the large cleaning session is for one week. The dirt on the weight adjustment inclined plate is caused by delayed cleaning of the site.

When the tablet press is running at high speed, a slight change in the filling position will directly affect the downward movement curve. It will inevitably affect the filling process.

6. Feeding blade speed setting error

With the increase of host speed, both chip weight and hardness will change. The feeding speed of GZPTS dual discharge tablet press changes synchronously with the speed of the main machine. The speed of the host increases, and the material separation speed also increases synchronously. The material separation speed varies for different varieties, and users need to promptly store technical parameters in the parameter formula for easy access.
