Testing and maintenance of pressing die of tablet press Usually the new die before leaving the factory has been tested by the manufacturer's inspection department after passing the factory, and will be accompanied by proof of quality qualified documents, foreign imported die will even be accompanied by the detailed data of each die. However, now many pharmaceutical factory procurement personnel like to buy some low quality die at a lower price, which requires users to do some necessary testing on the new purchase die before the official use, so as not to cause unnecessary losses. The same for a period of time after the use of the die can also do some sampling testing, to determine whether the die is still in a qualified state. Die is very precise, pharmaceutical factory users should establish a special die storage and storage system, ready to have a special storage room, indoor should be kept dry. After use, the die must be removed from the tablet press and cleaned one b

Structure device of capsule filling machine The structure of the automatic capsule filling machine is composed of empty capsule feeding device, capsule distributing device, powder feeding device, measuring plate mechanism, capsule filling and sealing mechanism, the main transmission mechanism in the box and electrical control system. 1) Empty capsule feeding device: it is composed of a hopper and a conveying pipeline, which mainly stores the empty capsules and makes the empty capsules vertically enter the general device of the capsules one by one. 2) Capsule distribution device: the empty capsule is put into the sorting fork of the distribution device. The downwards movement of the sorting fork will send six capsules at a time, and the rubber cap is on the top. At the same time, the vacuum separation system passes the capsule into the module and separates the body cap. 3) powder feeding device: it is composed of powder hopper, powder hopper screw, feeding conveying pipe, etc. It ma

The packaging significance of blister packing machine Pharmaceutical blister packing machine is a packaging machine used to pack oral solid tablets. The heating, molding and many other operations of plastic sheets are often completed in the same medical blister packing machine. In order to enable people to better understand this kind of mechanical equipment, the advantages of this kind of system equipment are summarized as follows: 1. Blister packing has good barrier property. The good barrier of such equipment is mainly determined by the packaging of the raw materials themselves. By comparing with bottled drugs, it can be seen that the drug can effectively reduce the required pollution after blister packaging and is convenient for patients to carry the drug. At the same time, after blister packaging, tablets also have obvious advantages in phase gas barrier, moisture permeability and many other aspects. 2. Another advantage of such packaging is the safety of drug packaging. T

Dose control of tablet press Different tablets have different dose requirements, and large dose adjustment is achieved by selecting different punch diameters of the die. After selecting the size of the die, the small dose adjustment is to change the actual length of the die hole after the back cover by adjusting the depth of the down punch into the die hole, so as to achieve the purpose of adjusting the filling volume of the drug in the die hole. Therefore, the tablet press should have a mechanism to adjust the original position of the punch in the die hole to meet the requirements of dose regulation. Control tablet thickness and degree of compaction The dosage of the drug is determined according to the prescription and pharmacopoeia and cannot be changed. Dosage pressure is also required for storage, storage and disintegration, which will affect the actual thickness and appearance of the tablet. Pressure regulation during tablet pressing is essential. This is achieved by adju

Tablet press selection reference In recent years, many tablet manufacturers have gradually approved the high-speed rotary tablet press from trial, and there is a tendency to replace the high-speed rotary tablet press. To explore the reasons, I believe that as long as there is a general understanding of the high-speed rotary tablet press people will say that the advantage is small, high efficiency, energy saving, the province of occupation, high information level. Taking the high speed rotary tablet press of our company as an example, a brief analysis is carried out around the cost performance, for the reference of the user selection. (1) High output. The output output of the high-speed rotary tablet press is 4 ~ 5 times that of the low-speed rotary tablet press for the same diameter and similar number of die presses. Namely in the same time to complete the same output, is the number of high-speed rotary tablet press and 4 ~ 5 sets of low speed rotary tablet press relationship.

Safety matters of blister packing machine 1. It is strictly prohibited to start the machine when the working frequency of the machine exceeds 40 frequency. When the four plates are blanked, the blanking times shall not exceed 56 times/min. 2. Press the manual right traction every time you press "start" or "dot move" to prevent the moving clamp from being damaged in the boot position. 3. When wearing PVC and loosening up and down the mold, the time of "loosening" should not be too long. Loosening 1-2 cm is enough to prevent the machine from being damaged to the greatest extent. 4. It is strictly prohibited to add lubricating oil during start-up or operation. 5. The feeding frequency in operation can be adjusted by the vibration frequency. 6. In operation, it is forbidden to clean the waste at the punching outlet, between the heat sealing roller and the driving roller, at the mold place, and at the batch number printing place. 7. No hard objects shall fall into the u

Insufficiency of tablet press equipment Although the performance of domestic tablet press equipment has been greatly improved, there are still many shortcomings in practical application: (1) the structure of the machine still needs to be improved, such as the tablet press maintenance needs to use lifting tools, manual lift the rotary table, disassembly time-consuming and laborious. And some foreign advanced tablet press, using the structure of the rotary table, up, down and track can be moved out with the rotary table, greatly shorten the time to change the mold, repair the machine; (2) the gap in machine performance. For example, when pharmaceutical factory uses 28 stamping machine, in the case of pressing special-shaped sheet, because the pressure needs to be adjusted higher, the spindle strength is not enough, the situation of breaking. This kind of spindle is hollow shaft, the reason that causes the break, has the design defect, also has the processing problem; (3) Equi

Blister packing machine feeding adjustment Carefully check each mechanical part of the equipment is abnormal, according to the provisions of the clearance and cleaning equipment. Check the connection of power supply, water source, air source and pipelines; Clear the obstacles around the body and check the fastening of bolts. Fill the machine with suitable lubricating oil according to the ambient temperature. Put the material to be packed into the hopper. Remove the cone plate sleeve outside the PVC bearing shaft, load the PVC drum into the bearing shaft, install the cone plate sleeve, and tighten the cone sleeve moderately. Boot, in "manual mode", open the "heating, heating, heat sealing heating" function, inching devices, make PVC through preheating zone, forming die, loading area, test area, heat sealing mould, drawing gas holder, indentation die, blanking die, install the waste after cutting edge to waste collection agencies, to complete the installation of the PVC.
