Rotary tablet press structure and principle

Rotary tablet press is suitable for the powder content ( More than 100 mesh) No more than 10% of all kinds of granular materials beginning tablet tablet press, does not apply to semi-solid, moist powder and particles of very fine powder. The structure and principle of rotary tablet press: first, the structure and performance characteristics: 1, this is, to adopt frequency conversion motor through the synchronous belt drives the worm worm wheel transmission so as to make the turntable rotate; Turntable rotate clockwise operation to drive 35 pay die. Pay per punch through the upper and lower guide rail and the roller of institutions such as feeding, filling, tablet, a piece of tableting process, etc. 2, the pressure of the machine, filling, slice thickness and speed are adjustable, all adjust the handwheel on the front of the machine, and the operation panel instructions. Simple operation, easy maintenance. 3, tablet press drive mechanism and the crushing chamber is completely isolated, in order to ensure the tablets conform to GMP requirements. In the tablet pressing chamber adopts non-toxic, no corrosion of stainless steel plate to it from the other part. Around all have sealing device, prevent contamination produced a job with the outside world. 4, pressure on the wheel the unloading device, the pressure can be adjusted, when the punch work pressure exceeds a preset pressure, by the spring compression to unloading, and by a buzzer sound and light signals, an immediate halt to the machine, in order to prevent damage of parts. 5, the machine adopts enclosed oil lubrication pay of worm and worm wheel transmission, prolong the service life of the worm gear for transmission. 6, on the guide rail of the machine, worm transmission, hopper, feeder, filling rail parts with ZP33 type tablet press. Native die conforms to the standard 'GB12253 - 9 ', and with ZP33, 19 type tablet press. 7, the machine is on either side of the board and back board are available dedicated keys to open, the machine repair and maintenance for convenience. Second, on the roller and the upper cover: 1, this device in the upper half of the machine, with four tension rod and the square around the periphery support to window closed interval with the pressure of the pressure for a little while and composition of crushing chamber. So tablet pressure regulating device is installed in this department sets. 2, tablet press pressure regulation by lever is rotating, the spring is compressed, the push rod in unloading state, effectively avoid the punch damage due to overpressure, moves to the right travel switch at the same time, the machine automatically stops and a sound and light signals, so that the operator check failure. 3, open on the roof at the top of the roller frame, can be injected into lubricating oil, to reduce the main shaft, bearing wear. 4, left the door open the machine can be used under the window installation conveniently punch and die by special tools play great dismantled in die. 5, the machine under the rail guide can also through the main window, dismantling, can not lift the turntable, the machine repair and maintenance of the operation simple and feasible. Third, rotary tablet press charging and the piece; 1, stainless steel hopper can be regulated through the hopper frame bolts hopper position of high and low, to control the flow of the material. 2, feeder is to make the pellets to fill in the mold, guarantee the weight of main parts, so it is the structure of the flow grid type, its bottom surface and changing the clearance of workbench face when installation is 0. 05 ~ 0. Between 1 mm, it can install feeder bolt to adjust. 3, to avoid the table size dust float in the sky, in the process of powder or tablet in working mesa was installed on the left side of the cartridge cleaner mouth, to reduce the accumulated powder. Otherwise will be punch glue powder and glue phenomenon. Pills after 4, in order to reduce the piece surface with powder, the machine will be a piece of mouth lengthen, facilitate should shake excess stock and collection.
