ZP-35D Rotary Tablet Press

1. The feature of machine structure

This machine is driven by motor through synchronous teeth belt linking with worm and rotation of rotary table drive 35 pairs stamps clockwise each stamp passes through flow-grid feeder, the mechanism of upper/lower rail and upper/lower press wheel will form the continuous tablet-pressing process of feeding, filling, tablet-pressing and output-tablet.

The peripheral cover is fully-sealed and made of Auce stainless. The table of internal pressing chamber and flow channel of tablet-pressing are all made of stainless steel and easy to clean without dirty corner. Through the transparent glass window leaf, we can observe clearly the status of tablet-pressing.

The side door board under the machine is very easy to open completely, and easy to clean, maintenance and repairing.

The tablet-thickness adjusting handle wheel and filling-controlling handle wheel are located at the front side, and the electrics operation panels is also right beneath the machine, which adopts frequency-conversion speed-adjusting, smooth and stable rotation, safe and correct. The safe unloading unit of upper pressing wheel make the setting of working pressure be adjusted freely. (There is a hand hole which can be opened on the top of the machine). When hen working pressure of impact lever is over the set value, the displacement of balanced spring make the upper impact wheel push off the upper impact lever, and the buzzer will give out a signal of sound and light. The machine will stop automatically to avoid overpressure at the impact lever to break.

The drive system is scaled in the oil tank under the main body of the machine, and it is an independent component which is fully separated, thus, they can’t be contained each other and the drive worm and worm wheel is dipped into the oil reservoir, the heat is easy to dissipate and wear-resist, thus the life of drive system is extended.

This machine is equipped with special vacuum auxiliary unit whit which can such up the rising dust in the pressing chamber, thus the pressing chamber is always under the negative pressure all the time, which is easy to form a clean circulation up to down circulating air to reduce the rising of powder dust.

2. The structure of rotary table

The rotary table is a main component which consists of upper/lower bearings and main shaft. There are 35 pairs of stamp is distributed evenly around the rotary table. The torque is delivered by power button between rotary table and main shaft, and it revolves only at clockwise (the stipulation is made by manufacture who has preset the motor’ s rotation controlled by frequency converter, it never, it never result in reverse rotation regardless of the arrangement of internal power supply phase sequence).

3. The structure of rail

The rail is cylinder cam and plane concaved wheel consisting of upper/lower rail, as well as the track of movement of upper/lower impact lever.

On the top of rotary table, the upper rail consists of upper/lower traveling rail of upper impact lever and parallel rail, which is fixed on the upper rail disc respectively and upper rail disc is fixed on the upper pressing wheel rack by screw. There is a revolve inlay tongue at the center o parallel rail, which is specially designed for dismantling or installing stamps. To avoid the damage to the machine, the machine can’t start until the inlay tongue have restored to its original position)

The lower rail consists of upper/lower traveling rail filling rail and bridge board which are installed on the main unit holder respectively. At the outlet of lower traveling rail, there is a round cushion which is specially designed for dismantling of installing lower Impact lever (at the rear of machine .the lower impact lever can dismantled or installed after the panel has been dismantled ).For the purpose of easy exchange of wear-out parts .the modularly constructed or installed directly under the main unit.

4. Filling-adjustment unit

The filling adjustment unit is designed for adjusting the weight of tablets, which consists of a pair of worm wheel and a pair of spiral. When revolve the adjusting handle wheel (installed on the peripheral cover of machine), the small worm drive worm wheel, which make worm move up/down, thus the filling rail installed on the bolt shaft will go up/down, and the volume of filling will be increased or decreased.

5. Tablet-thickness adjustment unit

This unit is designed for adjusting the thickness of tablet. It is perfected by means of adjusting the center position of lower pressing wheel, and it consist of eccentric shaft (lower press wheel shaft ) supporting lower press wheel, spiral gear, and when revolve the tablet-thickness adjusting handle wheel, the adjusting bolt will drive spiral and make the eccentric shaft revolve, thus the lower pressing wheel will change at the deviating distance, the center position of pressing wheel has been changed, and the distance between upper/lower pressing wheel will be changed correspondingly to meet the requirements of changing tablet thickness. After adjusting the filling and tablet thickness, the lock nut of adjustment handle wheel must be seared tightly to avoid the change of parameter during the period of maintenance.

6. Feed unit

Feed unit consists of feeder, bucket rack, column, adjustable screw and bucket. Both the space between feeder and the surface of rotary table and the height of bucket can be adjusted.

7. Drive components

The motor drive worm and worm wheel through teeth synchronous belt transmission and transfer to the motion of main shaft, there is a trial operation handle wheel installed on worm shaft. The degree of tightness of tightness of teeth synchronous belt can adjusted by motor, and the degree of tightness of belt is subject to less than 10mm bend after the thumb has pressed the surface of belt.

The worm and worm wheel is lubricated soak, and the level of oil can be observed through worm wheel box visual window, refill 20# mechanic oil until 1/3-2/3 of worm has been soaked. There is an oil-draining bolt installed on the side of worm wheel box.

The rotary tablet press complies with GMP requirements.

The high production efficiency satisfies large batch production demands.

It’s equipped with forced feeding device, various types of impellors are suitable for different materials to ensure the feeding precision.

The pre-pressure is consecutively adjustable which extends the pressing duration. The high speed rotary tablet press runs smoothly pressing complex materials.

The tablet pressing chamber is 360° dead angle, special installation is adopted for the tablet discharging mechanism, the under guide track and under roller are convenient to operate, dismantle and clean.

With special oil-resistance and dustproof system, the tablet press can effectively avoid mould blocking and provide its mould with increased damping coefficient.

An independent view window with high definition is designed for the high speed rotary tablet press.

Controlled by PLC and man-machine interface, it’s simple to operate.
