System operation mode of the tablet press By rotary tableting machine under punch, along the guide rail movement up and down, respectively, when the punch movement to die hole, upper punch upward movement feeder, lower punch through the CAM moves down, at this point, the upper surface of the punch and the die to form a cavity, powder particles after forced feeder blade wheel mixing concone fill the mould cavity, the punch through the drop-down excessive filling are formed when the low point of the CAM. The press press punch continues to move with the punching disc, and the down punch moves upward gradually when passing through the filling CAM, and pushes out the excess powder particles in the cavity. In the quantitative section, the upper surface of the filling CAM is horizontal, and the lower punch maintains the horizontal motion state. The quantitative scraper will scrape out the excess powder particles on the upper surface of the middle mold, ensuring the same amount of powder pa

How does blister packaging machine aluminum foil fold? Aluminum foil folding is a common problem in blister packaging machine. Due to the error of the packaging material reel, too tight or too loose brake at the rear end of the aluminum foil gas expansion shaft, the way of winding, and the difference in the degree of parallelism between the guide rods, aluminum foil sealing folding can be caused. First of all, encountered a long line of folding is the gas expansion shaft brake too tight, a little loose to solve the problem, such as the brake pad is not tight so replace a winding way to try, this problem generally appears in the aluminum foil drum material is not much time. Next if it is other fold first try will be close to the cutting board before heat sealing roller guide rod fixed when fold improvement, transfer of a second change the aluminum foil winding way, again observe the fold in the medial or lateral, if is the lateral will balance of heat sealing roller holder bolt lat

Application of powder press The properties of drugs and excipients should be similar. When pressing powder directly, the physical properties of drugs and excipients, such as heap density, particle size and particle size distribution, should be similar, so as to facilitate the even mixing. In particular, for drugs with small specifications and the uniformity of content, all kinds of excipients must be carefully selected. Insoluble lubricants used for powder direct pressing must be added later, that is, the raw materials and other auxiliary materials mixed evenly, then add insoluble lubricants, and to control the mixing time, otherwise it will seriously affect the disintegration or dissolution. In addition, when pregelatinized starch and microcrystalline cellulose are used as excipients, the dosage of stearin magnesium is large and the mixing time is long, and the tablet tends to soften, so the general dosage should be less than 0.75%, and the mixing time, rotation speed and strength

The molding method of blister packing machine Blister forming (negative pressure forming). The blister is formed by drawing the film softened by heating into the blister and forming the geometric shape. Blister molding generally adopts roller mold, forming bubble cover size is small, simple shape, bubble cover stretch is not uniform, thin top. Blow molding (positive pressure molding). Using compressed air, the heated softened film is blown into the bubble of the forming mold to form the bubble of the desired geometry. The wall thickness of the formed bubble cover is more uniform, the shape is quite wide, the bubble cover with large size can be formed, blow molding is used for plate mold. Punch assisted blow molding. With the help of punch, the heated and softened film is pressed into the mold cavity. When the punch is completely pressed into the mold cavity, compressed air is injected to make the film close to the inner wall of the mold cavity to complete the molding process. Punc

Lubrication of the parts of the tablet press The lubrication process of rotary sheet pressing machine should be noted as follows: 1. The lubrication of general parts of the machine is equipped with oil cup and nozzle on the appearance of the parts. Butter and oil can be filled respectively according to the type of oil cup. 2. The top cover of the glass oil cup is lubricated with the rotary table and bearings at 2-4 drops per minute during operation. 3. The oil cup of the screw cap on the worm is the lubrication of the worm and worm wheel, which is added according to the actual lubrication condition in operation. 4. The two ends of the transmission shaft are equipped with rolling bearings, and the shaft housing is equipped with oil nozzles, which can be refueled once every two weeks, and the oil gun is pressed in. 5. The tail of the punching rod and the curve rail guide shall be lubricated with butter. It shall not be too much, so as to prevent grease from seeping into the powde

Heating mode of blister packing machine Film conveyor blister packaging machine is a multi-functional packaging machine, each packaging process is carried out in different stations. The packaging machine is provided with a number of film conveying mechanisms, whose function is to transport the film and make it pass through the above stations to complete the blister packaging process. The conveying mechanism adopted by domestic various types of bubble wrap packaging machines includes groove wheel mechanism, CAM rocker mechanism, CAM indexing mechanism, ratchet wheel mechanism, etc., which can be selected according to the accuracy of conveying position, acceleration curve and the adaptability of packaging materials. The temperature at which the forming film is heated to the point at which it can be thermally formed. This temperature is determined by the selected packaging material. For hard PVC, the temperature range for easy molding is 110-150 ℃, within this range PVC film has suf
