The GZPK fully automatic high-speed rotary tablet press combines the technical features of domestic fully automatic high-speed rotary tablet presses and has made significant improvements in machine structure and operation control. The machine structure adopts a universal seat body, universal appearance, and can replace the punching plate body, thus achieving the interchangeability of multiple ideas for one machine. The operation control adopts industrial PLC automatic control, leaving a large development space and compatible with newly launched products (such as quick replacement of punching plate bodies).
The common problems and solutions of GZPK fully automatic high-speed rotary tablet press can be summarized as follows:
1、 The difference in film weight is too large
Reason and handling:
Poor particle uniformity: Uneven distribution of particle size leads to fluctuations in filling amount, requiring re mixing or sieving of excess fine powder.
• Insufficient fluidity: If the particles have strong adhesion or are damp, flow aids (such as micro powder silica gel) should be added or the granulation process should be optimized.
• Feeding system malfunction: Check if the speed of the forced feeder pulley matches the turntable and adjust the synchronization.
Out of tolerance punch size: Replace the qualified punch die with a length tolerance of ± 5 μ m.
2、 Pine flakes and fragments
Key measures:
Adjust pressure parameters: increase the main pressure or extend the compression time, and reduce the speed to improve molding.
Adhesive optimization: Choose the appropriate adhesive and control the dosage to avoid particles being too dry or too hard.
• Mold hole maintenance: Regularly check the wear of the punching and mold holes, and replace deformed molds.
3、 Adhesive flushing problem
Solution:
• Punch cleaning: Remove oil stains or rust on the surface of the punch, and lubricate the engraved part with liquid paraffin if necessary.
Environmental control: Maintain stable room temperature and humidity for tablet pressing (recommended humidity ≤ 50%) to prevent moisture absorption of materials.
4、 Abnormal operation of equipment
Systematic improvement:
Intelligent monitoring: Deploy digital monitoring such as pressure attenuation curve and temperature rise to predict the wear of transmission components.
Standardized operation: Develop material pre-treatment SOP (such as moisture ≤ 3%, vibration ≥ 15 minutes) to reduce failure rate.
Note: For the special working conditions of high-speed rotary tablet presses, it is recommended to regularly perform 3D dynamic balance calibration and bearing status monitoring to improve equipment stability.
