Classification of tablet press: Models can be divided into single punch tablet press, rotary tablet press, sub-high speed rotary tablet press, automatic high speed tablet press and rotary core tablet press.
The sheet shape pressed by the tablet press is initially flat circular, and later developed into shallow circular arc and deep circular arc on both sides, which is for the need of coating. With the development of special-shaped tablet press, oval, triangle, oblong, square, diamond, circular ring tablets followed. In addition, with the continuous development of preparations, due to the requirements of compound preparations and timed release preparations, special tablets such as double layer, triple layer and core coating are made, which need to be completed on special tablet press.
Rotary tablet press is a machine which is made of several pairs of die distributed on the turntable to make a circular lifting movement according to a certain track and press the granular material into tablet through the press wheel. And the stamping rod with the rotary table rotating speed ≥60m/min line press is called high-speed rotary tablet press, this high-speed rotary tablet press has a forced feeding mechanism, the machine is controlled by PLC, has the automatic adjustment of pressure, control the weight of the piece, eliminate the waste piece, print data, display fault shutdown and other functions, in addition to the control of the weight difference within a certain range, Quality problems such as missing Angle and loose lobe can be automatically identified and eliminated.
With the development of market demand, the scope of application of tablet press is more and more wide, no longer simply limited to the suppression of Chinese and Western medicine tablets, more widely suppressed health food, veterinary medicine tablets, chemical tablets: such as mothballs, washing blocks, smurf blocks, art powder, pesticide tablets, food tablets: chicken essence block, isatis root block, divine Qu tea block, compressed biscuits.

Experts believe that with the development of automotive electronics technology, automotive intelligent technology is gradually being applied. This technology makes the vehicle more and more simple to manipulate, with higher dynamics and economy, and better driving safety. Therefore, intelligence is the trend of future automobile development. The emergence of semi-autonomous or fully-autonomous operation vehicles in the future will help solve the traffic congestion problems faced by mankind, and will fundamentally solve the problem of car safety.
Du Jiangling, president of the General Research Institute of China, pointed out that in response to the challenges of modern car demand, the research on automotive technology will also change. From traditional petroleum-based research on internal combustion engines to automotive electrification and intelligence using electricity and hydrogen as energy sources. Research. He believes that the automobile society will enter the era of "car networking" in the future. "Car networking" is actually a new network that integrates the Internet and the vehicle-based Internet of Things.
In his concept, the "car networking" era of smart cars has the following characteristics: First, the car and the car can maintain a relatively fixed distance, can achieve zero collision; Second, the team between the car and the car is Randomly carried out, according to the owner's destination, through GPS positioning and automatic communication between vehicles, between the car and the car can be temporarily teamed up or left the team to improve traffic efficiency. The realization of these features, without exception, requires the development and application of automotive electronics products.
Therefore, the status of automotive electronics in future automobiles is not the imagination of automobile manufacturing experts, but the real needs of market demand and future automobile development. The application of automotive electronics technology has greatly improved the safety performance, emission performance, economic performance, and comfort performance of automobiles, as well as making cars more intelligent. It is considered a revolution in the development of automotive technology. This trend will be further accelerated and will bring about revolutionary changes in the automotive industry. The advent of the era of automotive electrification laid the necessary technical foundation for the development of intelligent cars.
As the intelligentization of automobiles is closely related to automotive electronics, the development of the automotive electronics industry will directly determine the level of smartness of automobiles. However, compared with the fast-developing automobile industry, the automotive electronics industry in China is still lagging behind and has become a short board that restricts China's auto industry from participating in international competition. According to Cheng Chuanhai, Chairman of FAW Qiming, the overall strength of China's automotive electronics is still very weak. The level of automotive electronics products is about 10 years behind the international advanced level. Domestic auto electronics are in the scale of enterprises, independent innovation, technological level, market development, etc. There are still gaps.
The "China Automotive Industry Development Report 2010" jointly compiled by the China Association of Automotive Engineers and the Development Research Center of the State Council has clearly pointed out that the autonomy of the automotive electronics industry is the key to industrial restructuring. At present, automotive electrification has entered various systems of automobiles. Data shows that the average foreign vehicle's electronic devices account for 20% to 25% of the total vehicle cost, and 40% for high-end vehicles. The ratio of China's automotive electronics products to the total vehicle cost is only 10%, which has to worry about the industry.
Autonomous development of the automotive electronics industry is the key to industrial restructuring. China's automotive electronics industry also has a broad market prospect. A survey shows that the average annual growth rate of the world's automobile accessory industry from 1990 to 2005 was 3.3%, of which the automotive electronic parts and components industry increased by 5.6% annually, and it is predicted that this growth rate will reach 6.4% from 2005 to 2015. Based on the market's promotion of vehicle safety requirements, energy conservation and environmental protection regulations, the proportion of the automotive electronics industry in the automotive industry will continue to increase, which provides a rare market opportunity for the development of automotive electronics products.
For the concept of future car “car networking†planned by people, more and more auto companies are trying to come in. It can be imagined that the future automobile controlled by automotive electronics will become the main force driving the green of the automotive industry.
Car Electronics opens the golden key to the car green future
With the development of social economy, the number of cars in China will increase significantly. At present, green energy-saving vehicles have become an inevitable trend in the development of the automotive industry. However, in the face of increasingly congested traffic and safety problems caused by the increase in automobiles, only “green†is not enough, and future new energy vehicles should be associated with vehicles. The combination of intelligence will become the development direction of the automotive industry.
