Preparation for the operation of the tablet press After the mold is installed, turn the steering wheel by hand and make the steering wheel rotate 2-3 times to observe the abnormal friction noise of the up and down impact lever on each track and each hole. The machine must have reliable ground wiring, connecting five wires to a three-phase power grid. The external vacuum cleaner is connected to the main machine. Turn on the main power switch, and the power indicator is on with the speed of 0. Press the start button of the vacuum cleaner and the operation indicator of the vacuum cleaner will light up. Now test the air capacity in the vacuum cleaner. Turn on the light switch on the screen and turn on the pressed light. In order to prevent the press from reaching the maximum speed immediately after starting, which may lead to negative overload of the press, the necessary working speed must be determined before the press runs. Press this key, or you can set the turntable speed you

Influencing factors of capsule filling machine The atmospheric fragmentation problem, i.e. the negative pressure vacuum can persuade the capsule to move from the capsule's turret to the capsule's mold base, and may lack both ends of the cloud capsule. It is necessary to verify that the quantization of external vacuum is rough when verifying individual devices. There are several reasons to have a body. The operator shall search and verify, for example, whether the rotating mechanism and conveyor tower of the capsule can flow synchronously with the copper seat sealing device under the mold seat; The reliability of each pipe joint of vacuum system; The mold and accessories are consistent with the number of capsules to ensure the normal operation of equipment and stations and increase the possibility of capsule charging. In addition, factors affecting the quality of automatic capsule filling include the occurrence of some common faults, if not dealt with in a timely manner, will a

Application of blister packaging materials The coating adhesion of coating layer thickness has a great impact on the process of printing, coating adhesion rigid PVC plastic adhesive layer is too thin, due to the lack of materials, the thermal pressure on THE PVC board will reduce the viscosity; Adhesive coating thickness is too large, not only increased the cost, but also increased the drying time, so should be kept in the appropriate thickness. Adhesive coating thickness is affected by adhesive concentration, coating tension, coating speed and anilox roller line number. With the adjustment of shape, depth, the number of lines per inch and the pressure of the two-roller contact line, the higher the adhesive concentration, the lower the film tension, the faster the film speed and the greater the film thickness. Therefore, the thickness of adhesive layer is usually adjusted by the concentration of adhesive and the tension of coater. For different varieties of aluminum foil, adhesive t

The role of small single stamping machine Applicable to pharmaceutical, chemical, food and other industries, suitable for all kinds of granular raw materials pressed into sheet products, especially suitable for laboratory, hospital and small batch production. Is a small continuous electric table press, when there is no electricity can be manual press, can press all kinds of granular, crystalline or flowing powder raw materials into flake, cylinder, ball, convex, concentric circle. It is suitable for pharmaceutical industry, pharmaceutical companies, universities, security products, food, agriculture, chemical industry, electronic battery, ceramic metallurgy and other industries, and can also suppress the products with characters, trademarks, patterns. The machine has only one mold, which can adjust the filling depth and stamping thickness of the material, that is, the weight, thickness and hardness of the product. Just change different mold, you can press down different products.

Factors influencing the quality of capsule filling Automatic capsule filling machine is one of the main equipment for GMP conversion in capsule preparation production unit. It is characterized by small volume, low energy consumption, quick mold change, convenient operation and easy cleaning. According to the motion state, automatic filling capsules can be divided into two main types: intermittent type and continuous type. It is also an economical and practical capsule filling equipment in the pharmaceutical industry. There are many factors affecting the quality of the automatic capsule filling machine, among which the powder filling agency and the capsule tower conveyor station are the important factors. The filling mechanism is mainly composed of six disks for measuring intermittent rotary motion, six disks for axial motion (axial position is adjustable) and one automatic feeding screw powder. The rotating measuring plate has six sets of cylindrical holes (measuring Chambers), t

Ink printing of blister packaging materials When high viscosity ink needs to be diluted with a large amount of diluent, add diluent agitation, so that the diluent evenly distributed in the entire ink. Measure between 20 and 30 with a viscometer. Room temperature and humidity will affect the concentration of ink, it is recommended to use ink concentration detector to determine the amount of added solvent, and according to the temperature and humidity changes, regularly determine the concentration of ink. When using intaglio printing to print aluminum foil products, the ink concentration is too low, which will lead to the color of the printed text pattern is not bright, and there will be paste phenomenon in the printing. Ink concentration is very high, so the pattern will produce cracking phenomenon, not only waste ink, and easy to cause the printing surface irregular, not beautiful. In addition, according to the speed of aluminum foil coater and gravure roller ink hole depth, choose

Save the die of the tablet press In the process of our drug production, the quality of the press die plays a crucial role. For example, when the punch hole is enlarged, the uneven weight will cause the drug to fail to meet the standard or produce cracks. The difference of the length of the tablet directly affects the difference of the weight and hardness of the tablet, and the uneven punch causes the crack or the fragmentation of the tablet; The punch has a curling edge or uneven, the effect will cause cracks, adhesive punch and so on. Therefore, in daily management, attention must be paid to the routine maintenance, maintenance and storage of molds to ensure the quality of tablets. In the daily management, I summarized the following process, hoping to be helpful for the daily maintenance, maintenance and storage of the die. 1. Newly purchased molds shall be checked and accepted by the workshop mechanic. After passing the audit, the unit leader shall confirm again, complete th

Blister packaging for aluminum foil printing Pharmaceutical blister packaging Aluminum-Doped Pharmaceutical Tablets printing process, capsule and coated paper industry pure aluminum, pharmaceuticals :PTP aluminum foil, aluminum foil coating machinery, gravure printing technology, standard method of the other end of the aluminum surface aluminum-plated and bonding layer process. The simple technological process is as follows: aluminum foil coiling - printing - drying - coating layer - drying - coating layer - drying - aluminum foil coiling. In the whole production process, the quality of printing mode and the surface resistance of heat sealant must be strictly controlled during the printing process to realize the adhesive layer of the protective layer, control the drying temperature of the speed and the coating voltage of the machine. Therefore, national medical standards for aluminum foil packaging have clear quality requirements for printed text surface properties of medicinal alum

Advantages and disadvantages of semi-automatic capsule filling machine Semi-automatic capsule filling machine is a kind of hard capsule powder filling equipment, widely used in laboratories, clinics, schools and small enterprises. Let's take a look at the advantages: Because it is semi-automatic equipment, so because the technical requirements are not high, the equipment construction cost is relatively low, the general price is relatively low. In addition, the size of the equipment is not very large, covering only less than 2 square meters. The above units or workplaces are relatively limited by the scale of production sites, and small scale is also an advantage. In addition to the above two points, semi-automatic capsule filling into the capsule filling requirements for materials are not high, can effectively fill fine powder or viscous powder. In addition, low noise, low energy consumption, easy maintenance of the equipment and cheap mold are some obvious advantages.

The tablet problem of the tablet press That is to say, when the pressing machine is running, the up and down movement may be abnormal, mainly because of the strong bond between the material and the mold, or even has occurred. This may be due to the high viscosity of the material, or due to the high humidity in the room, or due to the increased viscosity of the material as it absorbs moisture from the air, or due to insufficient lubricants or short mixing times. You can reduce the water content of the material, or choose a less viscous binder, or increase the amount of lubricant, or in small tissues, increase the amount of lubricant. One possible reason for the jumpers is that the speed of rotation on the table is so high that when the table and cover are rotated too strongly, the impact occurs, and this is enough to slow the table down. Rough edges, protruding edges of the tablets, are part of the working tablets that have redundant edges that can sometimes be pulled off by ha
