Structure of Forced Feeder of Tablet Press The influence of the structure of the forced feeder on the filling stability The structure of the forced feeder mainly consists of three parts, each of which is analyzed as follows: (1) the power conversion part, its role is to reduce the motor output shaft one-way rotation into the reverse rotation of the dial impeller, that is, the relative rotation of the two impellers, the material from the hopper down to the rotary table in the die hole; (2) the supporting part (that is, the auxiliary part), its role is to force the feeder positioning on the main body, the turntable has reliable and close positioning requirements; (3) the material impeller and the material cavity part, which is the part of the forced feeder that has a direct impact on the filling stability of the material. In the design of the impeller and the material chamber, the design should take into account this problem: is to ensure the flow of material; Still do not

The movement of the capsule filling machine Intermittent Capsule Filling Machine In the process of filling, the movement of the capsule is dependent on the dividing box for intermittent and discontinuous rotation. The filling quantity of the capsule is mainly determined by the volume of the metering plate hole. Hollow capsules in the capsule, hopper, automatic capsule filling machine main board up and down, the capsule on its own gravity into capsule guide groove, again by fork vertical plug so that it is capsule cap up, the capsule body downwards into the upper and lower in the module, and under the action of vacuum suction capsule, capsule cap separation, after the module into the powder filling station. The sensor in the filling ring of the capsule filling machine controls the spiral feeding rod above it, adding the powder to make the height of the powder in the filling ring constant. At the same time, the metering plate of the hard capsule filling machine rotates intermitt

Blister forming According to the principle that the bubble bubble forming is the PVC film (hard piece) heated through the mold and the use of compressed air or vacuum forming into the required shape and size of the bubble bubble, so when the forming bubble bubble problems need to be solved from the following aspects: (1) PVC film (hard sheet) whether qualified products; (2) whether the temperature of the heating device is too high or too low; (3) whether the surface of the heating device is adhering to P, V and C; (4) whether the forming mold is qualified, whether the forming hole is smooth and whether the pores are unobstructed; (5) Whether the cooling system of the molding mold works normally and effectively; (6) the vacuum degree and exhaust rate of the roller negative pressure forming can reach the normal value, and the pipeline has no abnormal loss; (7) whether the compressed air formed by plate positive pressure is clean and dry, whether the pressure and f

Principle and flow of stretch film vacuum packing machine The working principle of stretch film vacuum packing machine is relatively simple, that is, the stretch film vacuum sealing machine needs to use the molding mold, the film must be heated to a certain extent, and then the molding mold is used to fill the shape of the container, and then the product needs to be loaded into the molding of the lower mold cavity, and then vacuum packaging. Stretch film vacuum packing machine mainly has four workflow, vacuum, heat sealing, air return and circulation. The following is a detailed introduction: 1.Vacuum: The vacuum chamber of the stretch-film vacuum packing machine is closed. The vacuum chamber starts to vacuum when the vacuum pump starts to work. At the same time, the vacuum in the packing bag is vacuum. At the same time of vacuum operation, the two-position three-way solenoid valve IDT works, the vacuum of the heat-sealed gas chamber is kept, and the hot-pressed frame is kept in pla

The defective capsule is removed and adjusted The removal of defective capsules refers to the removal of the cap and body without separation of the waste capsule. Adjust the height of the suction nozzle: loosen the fastening top wire and adjust the height of the suction nozzle up and down, and then tighten the top wire. The suction nozzle can not be too low. If the suction nozzle is too low, it will suck off the capsule that has been opened in the module. The method of adjusting the height of the push rod: under the working table, loosen the lock nut on the joint bearing at both ends of the adjusting rod, and turn the adjusting rod to adjust the height of the push rod. The capsule with the body cap not separated is installed in the upper module of the fifth and sixth working positions. First, turn the main motor shaft with the manual handle to make the push rod move up and down, and observe whether the incomplete capsule is removed and sucked off successfully, and then tighten

Performance of aluminum foam cap machine Flat type aluminum-plastic bubble cap packing machine aluminum-plastic drum: includes two parts: aluminum-foil drum and plastic sheet drum. The drum is mainly composed of a cylinder body, inside and outside the stator, brake ring and adjusting nut, both ends of the cylinder body with rolling bearings on the supporting shaft, for the rotating part of the drum, when the traction of plastic film or aluminum foil, that is, to drive the roll material installed on the drum by the rotation. The stator is divided into inner and outer stators, which are sliding sleeve on the cylindrical surface outside the cylinder body and fixed at any position of the cylinder body by fixing screws to install and fix coils of different widths. The brake ring is set on the inner and outer cylindrical surface of the cylinder body, and is fixed on the support plate. It is the static part of the drum and is used to brake the cylinder body. Tighten or withdraw the 4 ad

Mechanical conditions of tablet press Tablet press is another element of sheet forming. The quality of tablets is directly affected by the performance of the specifications, the mechanical condition of the equipment in operation and some important parts of the tablet press, such as the wear of the die. (1) from the size of the model, rotary tablet press than the impact of the tablet press pressure, and uniform, sliver phenomenon is easy to control. Because the feeding hopper is fixed, the machine vibration is small, the particle stratification phenomenon is less, the sheet weight is accurate and stable. But the rotary tablet press has a variety of single-track and dual-track models. In the production of sliver, loose sliver, sheet weight difference, to consider the double track press speed, particle compression time is shorter than the monorail type, easy to produce sliver, loose sliver phenomenon. At this time should pay attention to the appropriate increase pressure, slow down

Capsules production equipment The filling of the drug is the most critical step in the manufacturing process of preparing the capsule. 1. Treatment of drugs (1) small dose of drugs or fine material drugs can be directly crushed into fine powder, through the six sieve, after mixing and filling. (2)large dosage of drugs can be partially crushed into fine powder, the rest of the medicinal materials extracted into thick paste and drug powder after mixing, drying, grinding, screening, mixing after filling. All the medicinal materials can also be extracted and concentrated into an extract, and then add appropriate auxiliary materials to make small particles, and then dry and mix and fill. (3) volatile oil should first be absorbed with absorbent or other drug powder in the prescription after filling, or after filling. (4) The drugs that are easy to be wet or eutectic after mixing can be diluted with an appropriate amount of diluent and then filled. (5) loose drugs are generally made in

Classification of packing machine (1) packaging machinery according to the degree of automation classification can be divided into automatic packaging machine and semi-automatic packaging machine. Automatic packing machine is a machine which can automatically feed packaging materials and contents, and automatically complete other packaging processes. Semi-automatic packing machine is a kind of machine which can automatically complete other packing processes by providing packaging materials and contents manually. (2) According to the type of packaging products, it is divided into special packaging machine, multi-purpose packaging machine and general packaging machine. Special packaging machine is a machine specially used for packaging a product. Multi-purpose packing machine is a machine that can pack two or more products by adjusting or replacing the relevant working parts. A general packaging machine is a machine suitable for two or more products within a specified range.

The cause of dust produced by rotary tablet press (1) Dust is produced in the process of manual feeding. (2) of the normal operation of equipment in the process of stamping pieces on the dust caused by: 1) have been four organic glass door adsorption, unable to see the tablet, to cope with the production of organic glass door to open, so that it has violated the GMP requirement. 2) charged tail into dust, dust by adsorption caused by lack of oil filling of lubricating oil regularly, if it is not clear in time, It often causes wear and tear of the upthrust tail and the upper rail guide, which makes the equipment unable to operate normally. 3) Dust produced by the equipment running for a long time will enter the electrical cabinet and cause electrical failure; 4) Dust will pollute the tablet room, and it is not easy to clean and disinfect the tablet room. (3) of the normal operation of equipment under the stamping process of dust, although have powder suction mouth suck, but in the ba
