【Product Name】：ZP37D Rotary type tablet press

This machine is a dual-pressure automatic rotation, continuous tableting machine, the granular materials into a agent. It is mainly used in pharmaceutical industry and also the chemical, food, electronics and other industrial sectors. Enclosing shield is fully Gua closed form, made of stainless steel, the internal table with stainless steel material, can keep surface luster and prevent cross-contamination, in line with GMP requirements. Doors fitted with transparent glass, can be clearly observed for tablets, side panels can be opened for easy internal cleaning and maintenance. All controllers and operating parts is reasonable. Frequency control devices for electrical control, easy to operate, smooth rotation, safe and accurate. Equipped with overload protection device, when the pressure overload, can automatically shut down. Implementation of mechatronics, construction and use of the touch screen display. Transmission sealed in the tank below the machine body is completely separate individual components will not produce oil pollution, and also allows transmission components infiltration in the oil sump, easy to heat and wear. The machine is equipped with vacuum devices, can suppress the absorption of clean indoor flying dust. Use damaged parts of the machine above the track, feeder, hopper, drive worm, pink and ZP33 gauges and other products with a common structure, gains on standardized, universal, and serialization. Currently domestic ZP-35 / 37D rotary tablet machine, the structure is basically the same, to distinguish between high and low quality, mainly to see the detail and process improvements.

I visited the plant in recent years, dozens of ZP-35 / 37D rotary tablet machine users, reflecting the effect of generally good, the only downside is: die replacement somewhat frequently. To address this problem, after careful analysis we found that when the user dies purchase, do not necessarily have been the original choice of tablet machine manufacturers die, and die from different manufacturers, although both by national standards, but there are some differences in the size of the total . In particular die round and neck size, the greater the difference. And I plant the original production of ZP-35 / 37D rotary tablet machine, rushed rails used is unilateral track, die hard when lifting less uniform, over time, could easily lead to punch small deformation, so that die shortened life expectancy. Meanwhile, the bottom rail exports undershoot downside thick, high enough orbital cavity, making some manufacturers irregular smooth enough when die head down, and even individual stuck phenomenon. According to the current production of non-standard conditions die, I plant on the ZP-35 / 37D rotary tablet machine to do the following improvements: First, pull the track from the unilateral change on bilateral, so that the die head line force uniform ; the second is to reduce the undershoot export slope downward track, the punch smooth derailment. After this improvement can be compatible with different manufacturers die, more importantly, greatly extending the life of the die, so that tablet quality is stable and lasting.

ZP37D rotary tablet machine electrical control core part of the adoption of the European classics; S7-200 series CPU224XP Siemens programmable controller, the new Shanghai Branch step; MT4404T man-machine interface and well-known brands Fu Ling inverter. Stepless speed regulation, can be smoothly adjusted turntable speed. Its simple operation control for the user. While the electrical part has a self-diagnostic function, through the display of alarm, can quickly locate the point of failure, improve maintenance efficiency.

Overall electrical performance in line with GB / T 5226 ---- 1 standard.

Above PLC control interface

The working process of the tableting machine can be divided into the following steps:

A lower punch punch site (its working position upwards) Central die hole extends into the lower end of the die hole, seal the bottom of the hole in the mold;

2, the use of the feeder to the drug filling the die orifice;

3, on the red punch site (its working position down) since the fall of the upper mold die hole hole, and certain travel downstream, the powder into tablets;

4, on the red ascend out of the hole. Undershoot rise to the top of the tablet in the die hole, to complete a tabletting process;

5, rushed down to the next place, ready for the next one to fill.

Tablet tablets mechanism works:

1. Dose control

There are a variety of tablets of different dosage requirements, high dose adjustment is accomplished by selecting a different diameter of the punch die to achieve. After choosing the size of the die, the tiny dose adjusted by adjusting the depth of the lower punch inserted into the die hole, so as to alter the actual length of the back after the die orifice, a die orifice to regulate

The purpose of the fill volume of the drug. Therefore, on a tablet machine should have adjusted undershoot in the mold of the original location of the hole institutions to meet dose adjustment requirements.

2. Thickness and compaction control pills

Dose is determined according to the pharmacopoeia of prescription and can not be changed. For storage, preservation and disintegration time requirements, tableting pressure on certain dose is required, and it will also affect the actual thickness and appearance of the tablets. Tableting pressure regulation is essential. This is accomplished by adjusting the hole punch in the mold to achieve the amount of downlink. Some tablet tableting machine with a punch not only during downward movement, but may also have a lower punch upward movement, by the upper and lower punch relative movement together to complete the compression process. But more than that to achieve a pressure regulator pressure regulator and control impulse downward adjustment amount by the institution.
