2. Technical Data
3. Main Function
3.1 PLC Control, automatic tablet weight controlling system, automatic batch rejection device, auto sampling function.
The average tablet control precision and single tablet weight tolerance should be in compliance with the above table. It is tested by placebo powder as per the standard formula, the fine powder will be more for small or thin tablet.
3.2 Color touch screen 12” in separate control panel, with the display of main average pressure, single punch pressure, alarm at fault, automatic stop and help menu, The on/off of tablet deduster and on/off and pulse of dust collector can be controlled by the touch screen (The tablet deduster and dust collector are optional).
3.3 Filling depth adjusted by servo motor;
3.4 Four sets of synchronous motor are used for adjusting main compression (tablet thickness), pre-compression. Control system is operated through the touch screen which display the value of main compression, pre-compression, and tablet thickness.
3.5 Main motor and feeder motor are adjusted with inverter, r.p.m. can be regulated continuously with upper and lower limit.
3.6 With accumulated running time, accumulated total output, accumulated good tablet output, and preset output shutdown function.
3.7 With alarm for main pressure overload, prepressure overload, auto protection facility for electric control system, main motor overload, feeder motor overload, upper and lower punches over tight, alarm for opening windows/doors and left/right side door in running, upper and lower camber installation. Emergency stop, filling decreasing start.
3.8 Automatic Lubrication system. Lubrication interval can be adjusted. Under lube alarm, lubrication pressure fault alarm and auto-stop protection. Lubricating point distributed to the upper punch body and head.
3.9 With powder low level alarm (alarm but not stop)
3.10 It has the security access management function in accordance with FDA 21 CFR Part 11. The touch screen has three levels of user rights management functions, and different rights correspond to different operation levels.
3.11 It has the data recording function in accordance with FDA 21 CFR Part 11. It can save, call and record the production parameter formula, and also record the production data and alarm information. The recorded data is saved on SD card in RDB or CSV format.
3.12 It has the audit trail record function in accordance with FDA 21 CFR Part 11. It can automatically record the user login / logout, main button operation and parameter modification of the system. The recorded data includes time stamp, user name and event description, which are saved on SD card in RDB or CSV format. Audit trail record, and you can also choose to a virtual printing documents as PDF format on the touch screen.
3.13 It has program backup / recovery function. Touch screen and PLC applications can be backed up and restored by SD card.
4. Main Structure Features
4.1 Main shaft and turret are rotated through whole worm reduction box driven by main motor and synchronous toothed belt; main motor and feeder motor are adjusted with inverter, r.p.m. can be regulated continuously with upper and lower limit.
4.2 Four-pole supporting rigid structure, three separated compartment for compressing, adjusting and transmission, cross contamination avoided. Gas spring concealed, organic glass windows. Concealed pipes and lines in tablet compartment.
4.3 Upper and lower camber track assembly relatively fixed. Double lifting cam. Up track made by copper alloy, others by nonmetal material.
4.4 Format by main compression and pre-compression, the compression could be adjusted continuously; pressure roller with rotational construction.
4.5 Main and pre-compression with rigid support, overload protection are realized by PC control pressure and auto decrease filling in process of forming.
4.6 Double layer force feeder system, better for equal filling, damping rod of lower punch with the structure of ball head piston.
4.7 Dust collection system with big wrap angle structure.
4.8 Partitioned middle coverplate, easy to remove, convenient for maintenance and clean.
4.9 All parts in contact with granule and tablets, such as filling system, middle turret and tablet ejection device, etc. are made of stainless steel or innocuous macromolecule material.
