How Tablet Press Machines Work? What is a Tablet Press Machine?Case

The working process of tablet press machine includes powder/granules material filling, measuring, pre-compression, main compression, tablets forming and discharging.

The upper and lower punches are driven by the turret and move from left to right along the upper and lower guide rails. When the punch moves to the filling section, the upper punch moves around the force feeder. At the same time, the lower punch moves down due to the action of the filling guide rail, forming a cavity with negative pressure in the middle die hole. The powder particles are let into the cavity by the impeller blending of the force feeder. When the lower punch is passing by the lowest point of the filling guide rail, it is overfilled. The turret continues to move, and when the lower punch is passing by the metering guide rail, it moves up gradually and pushes the excess powder particles in the cavity out of the middle die hole. Because there is much material in the feeder and together with the stirring action of the impeller, the powder of middle die is under a compression process when pushing out, which completes weight measurement of the tablets. The top plane of the metering guide is horizontal, and the lower punch keeps horizontal movement. The powder scraper scrapes away the excess powder on upper surface of the middle die, which keeps the same amount of powder particles in each hole. In order to prevent the powder in the middle die hole from being thrown out, a cover plate is installed behind the scraper. Before the middle die hole is moved out of the cover plate, the lower punch is just pulled down 2 mm by the lower punch protective guide rail, and the height of the powder in the middle die is also reduced 2 mm, so that the powder in the middle die will not be thrown out because of the high linear speed. After the middle die hole is removed from the cover plate, the upper punch enters the middle die hole gradually and cover the powder in the middle die closely, then upper punch and lower punch close. This process ensures that during the compression process the amount of powder leakage is small and the filling amount does not change. When the punch passes through the pre-compression roller, the pre-compression action is completed, and then continues through the main compression roller to complete the compaction action. Finally, through tablets discharge guide rail, upper punch moves upward, lower punch push upward, pushing tablets out for discharge, to complete a pressing process.

Main Transmission System

  • The main transmission system is for providing force for the tablet press machine. It not only provides sufficient torque, but also the speed is adjustable. So that, even under large impact loads, the speed is still stable and reliable.

  • The main transmission system mainly consists of high-power AC motor, frequency converter, synchronous belt, synchronous tooth belt, tensioning roller, hand roller, worm gear reducer, spindle and other components.

  • The main motor drives the worm gear box through the synchronous gear belt, the worm roller drives the main shaft. The main shaft makes the punch plate move so to rotate around the central shaft.

  • The main motor can realize more than 10 times stepless speed regulation by frequency converter.

  • The frequency converter itself has the intelligent control. The electrical system control fully displays the frequency converter's function, to realize the turret non-overload smooth start, stop; overload protection, breakdown alarm, breakdown shut down; speed and current display.

  • The synchronous toothed belt is adopted to reduce the noise of the equipment. The utility of belt tensioning mechanism reduces the slip rate of the belt.

Compression Force and Filling Adjusting Device
  • Tablet thickness adjusting hand wheel is used to adjust the distance between the upper main compression roller and the lower one (electric control on touch screen), so as to adjust the compression force applied to the surface of the tablet. Thus, it is also called compression force adjusting device.

  • The filling hand wheel is used to adjust the filling depth (that is, the filling amount). The hand wheel is connected with the control motor through the chain roller. Thus, the computer controller can adjust the filling amount by controlling the motor to operate the filling hand wheel in the automatic control state.

  • The pre-compression hand wheel is used to adjust the distance between the upper and lower pre-compression roller so as to adjust the pre-compression force.

Punching Combination

The punching combination includes punching plate combination, upper and lower punching rod, Middle Die, upper and lower pre-compression roller, upper and lower main compression roller, upper guide rail plate, filling device and lower guide rail plate. The upper punch is guided by an upper guide rail with continuous cam. The lower punch is guided by a lower guide rail, a filling guide rail, a metering guide rail, and a tablet discharge guide rail. The tail part of the upper punch and lower punch is embedded on the fixed curve guide rail. When the turret rotates, the upper and lower punch moves up and down along with the curve rail, to achieve tablets compression through the extrusion action of the compression roller.

Force Feeder

The force feeder is mainly composed of feeding motor, feeding worm gear reducer, universal coupling, force feeding device, feeding barrel, feeding inlet regulator, connecting pipe, feeding platform, platform adjusting mechanism, etc.

The feeding motor and the worm gear reducer are mounted on the upper part of the machine panel. The output shaft of the worm gear reducer drives the long shaft through the universal coupling. The long shaft is connected with the input shaft of the gearbox of the force feeder. The input shaft turns the gear shaft. The lower part of the gear box has two output shafts, which are respectively equipped with two impellers. Gears drive the two impellers to rotate mutually. A material collector groove is arranged at the bottom of the housing of the feeder. The lower part of the material collector groove is matched with the surface of the middle punching plate. It is used for filling the material in the feeder into the middle die. Two receiving scrapers are arranged at the front end of the material collector groove, which is for recycling the material on the surface of the middle punching plate into the feeder. On the upper part of the feeder, there is an observation window for observing the working conditions inside the feeder.

Upper and Lower Main Compression Roller System

The main structure of the upper and lower main compression rollers is basically the same. They are basically positioned by two cylindrical roller bearings to provide strong and large supporting force for the pressing roller. Two sets of tapered roller bearings are installed in the middle of the pressing roller, to ensure that the compression roller can rotate flexibly. In the middle of the two bearings, there is a spacer sleeve with two retaining rings on both sides, to ensure that the bearings in the compression roller do not rub against the retaining collars on both sides and damage the retaining collars.

The material of the compression roller is alloy tool steel. The hardness of the compression roller is higher than that of the die after processing, to ensure that the compression rollers do not wear out for long time use. The retaining collars on both sides are used for both positioning and sealing, to ensure that dust not entering the bearings under the working environment for a long time.

Pills/Tablets Discharge

The discharge system is composed of a guiding device and a discharge slot. The function of the guiding device is to guide the tablets out to the discharge device, and to guide the powder on the punching plate into the feeder.

The discharge device has two channels, namely the qualified channel and the rejection channel. The two channels are converted by a rotating electromagnet driving a flap (valve). When the machine starts to work or the rejects appears in the production process, the rejection channel opens. When the machine is in normal operation, the rejection channel is closed, and the qualified channel is opened. In the shutdown or emergency shutdown, qualified channel is immediately closed, and the rejection channel opens.

Oil Lubrication System

The machine has a new type of intermittent micro-flow quantitative automatic pressure oil lubrication system.

Oil lubrication system includes electric lubrication pump, oil filter, multi-channel oil distribution block, quantitative oil injector, pipe joint, pipeline and so on. The lubricating point is the upper guide plate, the upper punch, the lower punch, the main pre-compression roller, and the lower pre-compression roller.

Grease Lubrication System

Main lubrication points are upper bearing position of machine base, lower bearing position of machine base, upper main compression roller, lower main pre-compression roller shaft (manual butter gun filling)

Tablets Dust Collector

The tablet press adopts integrated dust collector to clean up the powder leaking from the middle and lower punching plates. It is with a vacuum cleaner. The suction pipe is directly connected from the fan to the back door of the equipment, and the inner pipe is connected to the suction device.

How Tablet Auto Weight Control Works?

This tablet machine realizes rejection through specially designed electrical system. This system is for auto weight control of the whole production process.

The principle of automatic weight control: the tablet weight is detected through the compression force given on it. If the tablet is under more compression force, then it has more weight. There is a scientific basis for expressing tablet weight by compression force. Under the condition of constant distance between the upper and lower compression roller, the compression force is mostly related to the amount of material in the middle die, and the amount of material in the middle die is directly related to the tablet weight. So, it's very scientific to measure and indicate the tablet weight by compression force. This picture shows how tablet press machine does tablet auto weight control.
