ZP-5/7/9 Rotary Press

ZP5A, 7A and ZP9A are mainly used to automatically and continuously press granular materials into circular, irregular and flaky objects with characters, symbols and graphics, whose diameter is less than 13 mm.

Characteristic:

1. Compressed sheet materials are particles with powder content not exceeding 10%. When pressing, the rotating speed, filling depth and thickness of the tablet can be adjusted.

2. The envelope is fully enclosed and the material is stainless steel, which can prevent cross-contamination and conform to GMP standard.

3. Open windows with transparent glass can clearly observe the state of tablets, and can be fully opened, easy to clean and maintain.

Working Principle and Main Structure

1. Turntable structure: Turntable is the main executive part of this machine. There are upper and lower bearing components, spindle, turntable and other main components. The die is evenly distributed around the turntable, and the torque is transmitted by a flat key between the turntable and the spindle. On the support of the spindle, the worm gear pair drives the spindle, splines are connected, the spindle is rotated, and the turntable is rotated.

2. Track mechanism: The track consists of a cylindrical cam and a plane cam composed of the upper and lower tracks, which are the trajectories of the lower and lower punches. Upper track consists of upstream track, upstream track, downstream track, one pupil track, upstream parallel track and downward track. They are respectively fastened to the upper track plate. The lower track consists of the down-rush up track, the down-rush up track and the filling track. They are mounted on the lower rail seat respectively.

3. Filling adjusting device: Filling adjusting tablet weight by day. The filling adjustment mechanism can be observed in the main body's interior and on the main plane. The filling amount can be controlled by rising or falling of the screw. When the disc is rotated, the clockwise filling amount decreases and vice versa.

4. Sheet thickness (pressing) adjusting device: adjust the thickness (pressure) of the sheet by adjusting the lower press wheel. The lower press wheel is installed in the groove of the main body. It is sleeved on the eccentric shaft, and the outer end is connected to the handwheel. When the external handwheel is adjusted, the eccentric shaft drives the pressure wheel up and down, which can also be used as a regulating device, but it is not adjusted in general.

5. Feeding device: The device consists of feeding hopper, adjusting screw, feeder, etc. The feeder is a lunar grating feeder, which is installed on the turntable. The clearance between the feeder and the working face of the turntable and the height of the hopper are adjusted according to the fluidity of the particles.

6. Transmission device: The transmission part of the machine is composed of motor, synchronous pulley, worm gear reducer, test driver wheel, etc. The motor is mounted on the base of the motor. After the motor is started, the power is transmitted to the reducer worm gear pair through a pair of synchronous belts. Motor speed is regulated by AC variable frequency stepless speed regulation. Opening both sides or back doors, you can directly observe and contact these other parts.

7. Shell part: The shell of the machine is fully enclosed and meets the requirements of GMP. The first half of the city is surrounded by four windows for easy cleaning and maintenance. The lower part of the stainless steel door is closed, which is usually locked and closed. Only when the die is repaired and installed, can the door be opened. An operating table is installed on the front of the machine. The pressing chamber and the transmission part of the machine are separated by a stainless steel enclosure, which ensures the cleaning of the pressing chamber and protects the transmission parts from powder pollution and corrosion.
