Since the reform and opening up, China's economy has grown rapidly and become the second largest economy in the world. In this process, China's economy has formed a unique development model, and its achievements have attracted the attention of the world. However, the "Pearl River Delta" model, the "Southern Jiangsu" model and the "Wenzhou" model are all based on China's huge demographic dividend, with high investment and large expansion as the driving force of development. Those models depend on the large-scale market and the support of the high proportion of labor force. With the continuous emergence of new forms of Chinese society such as aging, low fertility rate and informatization, China's economic model is gradually developing towards "Service", which will have a profound impact on the pharmaceutical industry and pharmaceutical equipment industry in the secondary industry。
Under a series of social and economic situations, such as the weakening of labor supply and changes in the values of the working population, what new demands do customers have for the core equipment of solid dosage--tablet press machine? What are the original needs amplified?
01 Demand is the direction
The core of the above contradiction is the lack of labor force, so the demand is centered on "people".
First of all, the higher requirements of employees in terms of income, safety and working environment pose new challenges to the performance and safety of tablet press machine;
Secondly, due to the improvement of employees' requirements, enterprises try to shorten working hours and non-production time;
Finally, in the face of increasing costs and fierce market competition, enterprises will spontaneously reduce all kinds of waste.
02 Performance of Tablet Press Machine
What is the performance?
The performance of the press machine refers to: 1. Speed, 2. Tablet weight control, 3. Stable Operation. In fact, these three aspects are not isolated, without accuracy weight control and stable operation is not the real high-speed tablet press machine. Therefore, it can be said that "Fast, Accurate and Stable" is Trinity.
What are the requirements for high performance?
1. Solid structure
The stability of the machine is the prerequisite of the performance, the mechanical parts bear the vibration impact during the process of tablet pressing, so that the accuracy is easy to lose. Vibration also has an adverse effect on the accuracy of filling and pressing pressure. Therefore, a solid structure is conducive to reducing the amplitude, protecting the accuracy and improving the fatigue life of parts.
2. Part Accuracy and Technical Level
The rotary tablet press machine usually has dozens of punch positions. In order to keep the same weight and hardness of the tablet pressed from each punch position, it is necessary to reduce the individual difference during filling and the non-uniformity during tablet pressing. This requires a high-precision turret and roller (turret to be very flat and roller to be very round), and it should be achieved not only at static state, but also when operation. Therefore, the bearing supporting rotation and the process of assembly are equally important.
3. Position Accuracy of Motion Mechanism
The production of different products requires different filling amount and pressing thickness. Even if the same product is produced, the site location needs to be adjusted refer to the change of the material bulk density and charging state. Therefore, the positioning accuracy and repeated positioning accuracy of the site are very important.
4. Precision Measurement System and Fast calculation
In the process of tablet pressing, the weight of tablet can't be measured directly. Usually, the weight of tablet is equivalent to the change of pressure value. Therefore, the "ruler" of measuring system is the key to judge. Tablet pressing is a continuous process with very fast speed, the collected pressure data should be converted from analog quantity to digital signal, and be calculated. The result will affect the system to issue commands such as waste tablet rejection, filling automatic adjustment, alarm and shutdown. Therefore, high-speed of acquisition, calculation and command can ensure that these actions do not lag behind.
03 Examples
Canaan 's T-Series High-speed Tablet Press Machine is in the forefront of the industry in terms of performance.
1. The four columns are installed on the four corners of the outer edge with the longest force arm and the best torsion resistance; Strengthening the column and pouring damping material can effectively reduce the amplitude;
2. High precision, high wear resistance punch and roller are manufactured according to European standard, equipped with the world's top bearings to make the core parts run more smoothly, with low heating, low noise and long service life;
