Capsules filling and quality inspection Prepare empty capsules with contents The empty capsule is divided into two sections, called cap and body respectively. Empty capsules can be divided into three types: colorless transparent, colored transparent and opaque according to whether they have color or not. According to the type of lock, it is divided into two types: ordinary type and lock type. According to the size, it can be divided into eight kinds of size: 000, 00, 0, 1, 2, 3, 4 and 5, among which the largest size is 000 and the smallest size is 5. Contents can be prepared into different forms according to drug properties and clinical needs, mainly in the form of powder, pellet and pellet. Fill the empty capsule Mass production can be fully automatic capsule filling machine or semi-automatic capsule filling agent to fill drugs, drugs filled with capsule polishing machine to remove the adsorption on the outer wall of the capsule fine powder, so that the capsule clean. A small am

The forming method of bubble cap machine Molding is an important process in the whole packaging process. The bubble cap molding method can be divided into the following four kinds. ①Blister molding (negative pressure molding). The film, which is heated and softened, is sucked into the socket of the foaming pancreas to form a certain geometric shape, so as to complete the foaming. Blister forming generally adopts roller mold, forming bubble cap size is small, the shape is simple, the bubble cap stretching is not uniform, the top is thin. ② blow molding (positive pressure molding). The film softened by heating is blown into the socket of the bubble cap of the forming mold by compressed air to form the bubble cap with the required geometric shape. The wall thickness of the formed bubble hood is relatively uniform, and the shape is quite wide, and the bubble hood of large size can be formed. Blow molding is mostly used for plate mold. ③ the punching head auxiliary blow molding. With th

Clean the parts of the capsule machine Cleaning of dose plate and filling rod: 1. Rotate the shaft of the main motor with the handle to make the filling rod in a high position, loosen the cover nut and rotate the knob clockwise to make the plate filling gripper rise, lift and take down. 2. Loosen the small pressing plate screw with a long hole under the gripper, and remove the filling rod. 3. Unscrew the fastening screws at both ends of the powder holding ring cover plate, then remove the powder holding block plate, loosen the four fastening screws that fix the powder holding ring, slowly lift the powder holding ring and the cover plate away from the dose plate and take them out together from the side without removing the filling rod plate seat. 4. Use a special wrench to remove the three screws fastening the dose disc, and then remove the dose disc and the sealing ring. 5. Wipe the removed parts in purified water with clean cloth repeatedly, so that there is no visible attachmen

Stretch film vacuum packaging machine maintenance In order to ensure the normal operation of the equipment and prolong its service life, it is necessary to strengthen the maintenance work in use. 1. should be in the temperature 0℃-40℃, relative humidity is not more than 85%, no dangerous and harmful gases in the surrounding air, no powder flying, all safe and explosive dangerous goods in the environment. Additional accessories are required for special circumstances. 2. The oil level of the vacuum pump should be checked regularly to keep the oil level in the 2/3-3/4 position of the oil window; The vacuum pump adopts imported oil or special oil for No. 0 vacuum pump, and the imported vacuum pump should adopt special imported vacuum pump oil. 3. When the oil in the pump is observed to be black or milky white; If there is water in the oil or the viscosity increases, it is proved that the oil has been contaminated. The vacuum pump oil should be replaced immediately. Under normal circums

The structure and shape of the die of the tablet press The punching die is a tablet press mold for pressing tablets. The working end faces of up and down punching form the surface shape of tablets. The diameter of the middle die is the diameter of tablets. Die is an important task of the tablet machine components, usually including a pair of die, in the mold, the impact on three parts, rushed up and down the structure similar to that of the punch diameter are equal, the upper and lower diameter of punch and die die in combination, can free sliding up and down, in the die hole in but can not exist leakage clearance of powder. According to the structure and shape of the die, it can be divided into circular and special-shaped (including polygons and curves). The shape of the end face of the punch is flat, hypotenuse, shallow concave, deep concave and comprehensive shape, flat and hypotenuse punch is used to suppress flat cylindrical tablets, shallow concave is used to suppress double c

Pressing wheel failure of tablet press and its solution The pressing wheel part can be divided into the upper pressing wheel and the lower pressing wheel, which is also the device to adjust the pressure of tablets and increase the protection. The common failure problems are: (1) pressure wheel wear (2) the pressure wheel shaft bearing is short of oil or damaged Analysis and solutions: (1) the serious wear of the outer circle of the pressure wheel leads to large positive force at the tail of the punch rod. The pressure wheel must be replaced. When the inner hole of the pressure wheel and the pressure wheel shaft are seriously worn, the pressure wheel or the pressure wheel shaft must be replaced. In addition, sometimes the fracture of the press wheel shaft is mainly caused by excessive pressure. Most of the fracture is caused by improper adjustment of the material pressure. At this time, the press wheel shaft needs to be replaced, the material needs to be adjusted and the

The turntable failure of tablet press and its solution The turntable of the rotary tablet press is a circular disc, and the punching rod holes and the middle die holes are evenly distributed in the periphery. When the punching rod rotates under the drive of the main shaft, the punching rod moves up and down along the curved guide rail, so as to complete the tablet pressing process. The rotary table is the main working part of the tablet press. In the continuous working process, the common failure problems are: (1) punch hole or die hole after long-term wear caused by two holes coaxiality does not meet the requirements (2) The upward movement of the turntable affects the filling or the flake release (3) the loosening of the top wire of the middle die causes the upward movement of the middle die (4) the top wire of the middle die does not work Analysis and solutions: (1) in the process of use, punching rod hole and die hole due to different degrees of wear will likely appear diffe

Stretch film continuous sealing machine adjustment method In order to adapt to different bag specifications and thicknesses, continuous sealing machine makes the conveying table height, sealing temperature, sealing machine running speed and so on adjustable during production. The following is a summary of the methods of continuous sealing machine to adjust each part 1. Adjustment of conveying table height: loosen the adjusting nut of hanging wheel height with crescendo plate, then loosen the adjusting knob of conveying table height cutting, pull the conveying table upward with both hands to the desired position, tighten the adjusting button of conveying table height and adjusting nut of hanging wheel height. 2.conveyor in and out adjustment: if need to adjust the conveyor in and out, loosen the two sides of the conveyor out adjustment knob, two hands to move the table outside, move to the required position, tighten the two conveyor in and out of the cutting knob. 3.vertical

Compressibility of tablet material Compressibility refers to whether the material is easy to compress into sheet performance. The formability of the material can be evaluated by hardness, tensile strength and elastic recovery rate of the tablet. The tablet should be of the right hardness and should also ensure that the tablet disintegrates quickly or that the drug dissolves too quickly. When the content of the main drug in the tablet is small, pharmacy method should be used to achieve the purpose of uniform distribution of the drug, under normal circumstances, it is appropriate to use simple excipients; When the content of main drug in tablets is large, attention should be paid not only to the fluidity and compressibility of excipient, but also to its capacity and the amount of excipient, and also to the influence of particle size and form of active ingredient on the compressibility. Compressibility is related to the plasticity and elasticity of raw materials and the microscopic stat
