Working Principle of Rotary Tablet Press Machine:

For the pharmaceutical industry, a rotary tablet press machine can automatically or manually compress granular or powdered western medicine powder into tablets of different sizes.

The working principle of the rotary tablet press machine is to install multiple punches on the working turntable in a circular shape, and the tails of the upper and lower punches are controlled by fixed lifting guide rails; the working turntable is driven by the transmission equipment to rotate, so that the upper and lower punches follow the It rotates synchronously, and at the same time it is controlled by the guide rail to make an axial lifting movement. The particles in the stuffing bucket are continuously added to the die; there are pressure rollers on the upper punch and the lower punch. Continuous compression into tablets and continuous film out.

The speed of the turntable, the filling depth of the material and the thickness of the tablet can be adjusted when the rotary tablet press machine is pressed. The mechanical buffer device on the machine can avoid damage to the machine parts caused by overload. The machine is equipped with powder suction box. The dust generated when the machine is running can be sucked through the suction nozzle to avoid sticking and clogging, and the raw materials can be recycled for reuse.

Rotary Tablet Press Machine Structure:

1. Turntable structure: The turntable is the main executive part of the machine. It consists of upper and lower bearing assemblies, main shaft, turntable and other main parts. The main shaft is supported on the bearing, driven by the worm gear pair, connected by splines, and the main shaft is driven to make the turntable rotate.

2. Track mechanism: The track has a cylindrical cam and a plane cam composed of an upper track and a lower track, which are the tracks of the upper and lower punches. The upper track is composed of several pieces of rails, such as the upper punching upper rail, the upper punching lower rail, the upper punching upper parallel rail, the upper punching lower parallel rail, and the lowering rail. They are respectively fastened on the upper track disc. The lower track is composed of the upper punch rail, the lower punch rail and the filling rail. They are respectively installed on the lower track seat.

3. Filling adjustment device: The filling adjustment is used to adjust the tablet weight. The filling adjustment mechanism is installed inside the main body, and the moon-shaped filling rail can be observed on the plane of the main body. It rises or falls by the action of the spiral to control the filling amount. When the disc is turned to adjust, the filling amount decreases clockwise, and vice versa. increase.

4. Sheet thickness (pressure) adjusting device: Adjust the sheet thickness (pressure) by adjusting the lower pressure roller up and down. The lower pressure 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 hand wheel. When the external hand wheel is adjusted, the eccentric shaft drives the pressure wheel to rise and fall, that is, to adjust the thickness (pressure) of the sheet, so as to To control the thickness and hardness of the tablet, the up and down adjustment of the upper pressure wheel can also be used as an adjustment device, but it is not adjusted in general.

5. Feeding device; the device is composed of a feeding hopper, an adjusting screw, a feeder and other parts. The feeder is a moon-shaped grid feeder, which is installed on the turntable. The gap between the feeder and the working surface 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 rotary tablet press machine is composed of a motor, a synchronous pulley, a worm gear reducer, and a test handwheel. The motor is installed on the motor seat of the bottom plate. After the motor is started, the power is transmitted to the reduction worm gear pair through a pair of synchronous belts. The electric speed is adjusted by AC frequency conversion stepless speed regulation. Open the sides or the rear door to directly observe and access these parts.

7. Shell part: the shell of the rotary tablet press machine is fully enclosed, which meets the requirements of GMP. There are four windows in the upper part, which is convenient for cleaning and maintenance. The lower part is closed with a stainless steel door, which is locked and closed under normal conditions, and the door is only opened when repairing and installing the die. An operating table is installed on the front of the machine. Thetablet press machine room and the transmission part of the machine are separated by a stainless steel enclosure to ensure the cleaning of thetablet press machine room and to protect the transmission parts from powder contamination and corrosion.

ZP Series Rotary Tablet Press Machine Features:

2 The mechanical operation can be clearly seen with the transparent protective cover. And can be fully opened for easy cleaning and maintenance.

3 The speed is steplessly regulated and can be adjusted arbitrarily.

4 Realize mechatronics, use touch keys and display screen (speed, output, fault) and other displays

5. The transmission system is sealed in the oil tank under the main body of the machine. It is an independent component that is safely separated and will not pollute each other. The transmission shaft is infiltrated into the oil pool to be fully lubricated, reducing noise and wear.

6 Mechanical dust collection device can absorb the dust in the pressing room.

Precautions for Use of Rotary Tablet Press Machine:

1. Do not remove the protective cover and safety cover device on the rotary tablet press machine.

2. The punching die must undergo strict flaw detection test and appearance inspection, and it must be free of cracks, deformation, missing edges, suitable for hardness and accurate in size. If it is unqualified, do not use it to avoid serious damage to the machine.

3. The feeder device is level with the turntable surface, and the height is accurate. If it is too high, powder leakage will occur, and if it is too low, copper scraps will fall off and affect tablet quality.

4. Do not use raw materials with a lot of fine powder, because it will cause more flying powder in the upper punch and more leakage in the lower punch, which will affect the easy wear of the machine parts and the loss of raw materials.

5. Do not use raw materials that are not dry, as it will cause the powder to stick to the punch face.

6. If there is a jumping piece or stagnation during operation, it must not be picked up by hand, so as not to cause hand injury accidents.

7. When starting up, start the motor first, and then start the clutch after it runs normally.

8. If you find abnormal vibration or abnormal noise during use, stop the machine immediately for inspection.

9. The pressure should not be too high during use. Generally, it is measured by the load of the motor. It is normal for the heavy-load current of a 380-volt motor to not exceed 4 amperes when pressing tablets.

10. Increase of difference in tablet weight: During the process of adding tablets, the difference in weight cannot exceed the limit stipulated in the Pharmacopoeia to be qualified.

Adjustment Method of Tablet Weight of Rotary Tablet Press Machine:

During the tablet compression process, it is often found that the difference in tablet weight increases. The reasons and treatment are as follows:

(1) The length of the punches is uneven: it is easy to cause the difference in sheet weight to increase, so use a caliper to check each punch before use before use. If there is an individual decrease, it may be due to the failure of the lower punch movement, resulting in less filling of the particles. It is necessary to check out the individual lower punch and remove the obstacle.

(2) The height device of the hopper is wrong: it can cause the particles in one hopper to fall fast, while the particles accumulated on the feeder are more, the speed of the particles in the other hopper is slower, and the accumulation on the feeder The number of particles in the two feeding hoppers should be kept at a certain amount and the falling speed is equal, and the particles accumulated on the two feeders are similar, so that the particles can Evenly into the mold hole.

(3) Blockage of the feeding hopper or feeder: When pressing tablets, if the particles used are small, viscous or wet, and occasionally cotton yarn ends and foreign matter from tablets are mixed in the particles, the flow is not smooth, so that the particles added to the die hole are reduced. 1. Affect the weight of the tablet. If the weight of the tablet suddenly decreases, stop the machine immediately for inspection.

(4) Tablet weight changes caused by granules: too wet granules, too much fine powder, too large difference in granule thickness and insufficient lubricant in granules can also cause changes in tablet weight differences, and the quality of granules should be improved.

(5) The reason for the change in tablet weight is generally caused by the failure of thetablet press machine or negligence in work. Therefore, during thetablet press machine process of the rotary tablet press machine, the machine parts should be well maintained and the machine parts should be inspected in detail. Whether there is any damage, and weigh the slices every certain time (10-20 minutes), and the slices coincide with the regulations.

Daily Maintenance of Rotary Tablet Press Machine:

1. Regularly check the parts, 1-2 times a month. The inspection items are whether the crankshaft, upper and lower rail guides and other movable parts are flexible and worn. If any problems are found, they should be repaired and used in time.

2. After one use or shutdown, the remaining powder should be taken out, and the residual powder in each part of the machine should be cleaned. If the shutdown time is long, all the dies must be removed, and the machine must be wiped clean to ensure that the smooth surface of the machine is Apply anti-rust oil and cover with cloth.

3. The maintenance of the punching die should be placed in a covered metal box, so that the whole punch of the punching die is fully immersed in the oil, and it must be kept clean to prevent rust and bruises. Try to customize the iron box and pack one box for each specification. , which can avoid wrong installation and help to grasp the damage situation during use.

4. The place of use should be cleaned frequently, especially for the manufacture of medicine and edible tablets, and there should be no dust, sand and flying dust.
