The main structure and working principle of the rotary tablet press
Rotary tablet press is a double-pressure automatic rotating and continuous tableting machine. It is used to compress granular raw materials into tablets. It is mainly used for tablet production in the pharmaceutical industry, and is also suitable for chemical, food, electronics and other industrial sectors. . The outer casing is fully enclosed and the material is made of stainless steel to maintain surface gloss and prevent cross-contamination, in line with GMP requirements. Doors and windows with clear glass provide a clear view of the state of the tablet and can be fully opened for easy internal cleaning and maintenance. The frequency control device is used for electric speed regulation, which is convenient to operate, stable in rotation, safe and accurate. The hydraulic system is designed to ensure the stability of the hydraulic system. Equipped with overload protection device, it can automatically stop when the pressure is overloaded. The die can be used with ZP19, ZP33, ZP35 tablet presses. Rotary tablet press structure features: 1. The upper part of the machine is a tablet structure: its composition is mainly composed of three parts: upper punch, middle die and lower punch. The surrounding 19 punches are evenly arranged on the edge of the turntable, and the tail of the upper and lower punches. Embedded on a fixed curved guide rail, when the rotary disc rotates, the upper and lower punches are lifted and moved along with the curved rail guide to achieve the purpose of pressing. working principle Punching and die: Punching and die are the basic components of the tablet press. Each punch is composed of three parts: upper punch, middle die and lower punch. The structure of the upper and lower punches is similar, and the punch diameters are also equal. The upper and lower punches are matched with the die holes of the middle die, and can slide freely up and down in the middle die hole, but there is no gap that can leak the powder. . Die processing dimensions are uniform standard sizes and are interchangeable. The specifications of the die are expressed by the diameter of the punch or the diameter of the middle die, which is generally 5.5-12 mm, and each 0.5 mm is a specification with 14 specifications. Punches and dies are subjected to a large pressure during the tableting process, and are usually made of bearing steel (such as crl5) and heat treated to increase their hardness. There are many types of punches, and the shape of the punch depends on the shape of the tablet. According to the shape of the die structure, it can be divided into a circular shape and a special shape (including a polygonal shape and a curved shape); the shape of the cross section of the punch has a planar shape, a beveled shape, a shallow concave shape, a deep concave shape and a comprehensive shape. The flat and beveled punches are used for pressing flat cylindrical tablets, the shallow concave shape is used for pressing biconvex tablets, the deep concave shape is mainly used for pressing the coated tablets, and the integrated shape is mainly used for pressing. Shaped piece. In order to facilitate the identification and taking of drugs, the name of the drug, the dose and the vertical and horizontal lines can also be engraved on the end face of the die. For tablets of different doses, a suitable size should be selected. The above is all the content shared today, I hope to help you use this device in the future. Fluorine-Containing Benzaldehyde Most products of Fluorine-Containing Benzaldehyde are a pale yellow liquid. They are playing an important role in fine chemical intermediates, is used as the main raw material for the synthesis of a variety of pesticides, pharmaceuticals, surfactants, polymer monomer mildew. As used in medicine synthesis antihypertensive drugs, antipyretic analgesic anti-inflammatory drugs, anti-cancer drugs, muscle relaxation drugs for synthesizing fluorine cypermethrin, fluorine chlorobenzene daisy cool in pesticides, fluoride and styrene, wherein the polymer of styrene monomer to fluorine can be widely used in the manufacture of the recording material, a thermoplastic resin coating, liquid crystal materials. Currently new miticide is effective pesticide products which is the main raw material of Fluorine-Containing Benzaldehyde.

2, the main work process is divided into: (1) filling; (2) tableting; (3) filming. The three procedures are carried out continuously, and the filling and tableting have an adjustment control mechanism, with a nameplate description, and the operation is simple.
3. This machine adopts a flow grid type feeding mechanism, which can make the material evenly fill the die hole and reduce the difference of the die weight.
4. The motor is installed in the machine base, the worm drive turntable is driven by the V-belt, and the stepless shifting pulley is arranged on the motor shaft. The speed can be adjusted arbitrarily by the movement of the motor, and the use is safe and reliable without noise.
5. The side of the machine base is equipped with a powder suction box, which has a blower, a powder storage room and a powder filter room. When the machine is running at high speed, the powder of flying powder and medium mold falls, which is excluded by the powder suction nozzle, and is not sticky. The knot is plugged and kept running smoothly and normally.
