Automatic operation of tablet press (1) Check whether the tablet press machine source meets the requirements of working conditions, and whether the upper and lower compressors are wiped clean. The high pressure of the tablet press is adjusted to the high pressure required by the tablet press, and the delay time under the high pressure is set (generally 5 seconds). (2) Under the premise that the power supply meets the requirements of the working conditions, the upper and lower indenters are wiped clean, the high pressure debugging is good, and the delay time is set well, the sampling spoon is used to take an appropriate amount of the grinded sample into the tablet box, and the tablet box is accurately placed in the central position between the upper and lower indenters. (3) Open the main power supply and motor power supply, press the start switch, the indicator light of the start switch is on, the lower pressure head starts to automatically rise to the contact sample, start to

Tablet press pressure size difference 1. the speed of the tablet, the speed is slow, the time of the pressure can be longer, and the hardness can be better. 2. The relationship between the pressure and hardness of the tablet press is proportional to the range of pressure changes; 3. The pressure of the tablet press has a great relationship with the hardness of the tablet, there is a zero point, when the pressure is very high, the film is likely to sliver, so it is not a constant pressure can be pressed into the film. In addition, the optimization of tablet pressing: 1) Adding microcrystalline cellulose with good compressibility is beneficial to the hardness of tablets 2) if the particles are too wet, after adsorption with silica gel, then pressure, hardness will soon come up 3) Sodium carboxymethyl cellulose can increase the hardness, different viscosity, you can try the CMC difference of different viscosity

Tablet press die ordering problems to pay attention to In order to make the drug factory users can better order the appropriate die, this paper makes some simple introduction, and it is suggested that the drug factory users can first have a full discussion with the die manufacturer, in order to reduce the problems that may arise during production. 1. Due to some characteristics of track design and processing technology, it is suggested that users must choose products from the same factory for tablet press and die. Do not blindly pursue cheap and buy inferior die, resulting in the damage of the tablet press. 2. Choice of tablet type: Correct choice of tablet type is a successful step for the tablet press. For example, chewable tablets have high requirements for hardness and can be easily chewed. Most of them are inclined flat tablets. Shallow concave for thin film coating. Because there is no adhesive and lubricant in the raw material of traditional Chinese medicine tablets, it is re

Lubrication and maintenance of tablet press (1) all moving parts on the surface of the friction lubrication is to ensure that the machine run properly and prolong the service life of the important link, especially if the main moving parts under the condition of lack of oil dry transit transfer quickly damage and cannot be used, so the tablet machine before use must be full cup of oil, oil hole, and the friction surface and lubricating oil, and empty operation make the friction surface is full of oil film, and then can be put into use. From now on each shift refueling on time, but each refueling should not be too much, so as not to spill affect cleaning, stained tablets. (2) Each shift must check whether the screws are loose, in the process of work should also pay attention to check, if there is loose tighten immediately, so as to avoid failure. The main parts are: the upper punch fastening nut, the middle die fixing screw, the lower punch fixing screw; Connecting rod locking nut,

Tablet press has a variety of technologies New tablet press and tablet technology emerge one after another. 1. Increasing pre-pressure and improving tablet quality are common considerations of many tablet press manufacturers when they launch new products. At the same time, the main pressure and pre-pressure are the same, which brings great convenience to assembly adjustment, manufacturing and product type. 2. In order to improve the utilization rate of the equipment, reduce the cost of the equipment, and make the cleaning of the equipment more standardized, the concept of WIP in-place cleaning has been implemented in more tablet presses. Foreign advanced tablet press manufacturers also pay great attention to the research of the top output, many specifications and models of the tablet press has been added in the control system of the top output display. Although China's tablet press and tablet technology has developed rapidly and made great achievements, compared with develo

Tablet press mold processing About processing, blanking (before heat treatment), grinding plane, tablet type, coarse car size, quenching, tempering, cleaning, external grinding, centerless grinding, flat grinding, external grinding, polishing, inspection, packaging, the general process is like this. Says the most common mold and cheap, namely ZP series, using the bearing steel processing mould, they are what kind of process, the previous file process take not processing, rough turning directly the file size (piece of cup noodles is also direct car), hardening, grinding, centerless grinding, flat grinding, polishing, inspection, packaging. This process can not maintain the consistency of the sheet (because it is out of the car) and then temper the next process, the internal stress of the material elimination. The following process will continue. The mold process of high-speed tablet press is basically the same as the above, individual manufacturers temper the mold after quenchi

Tablet press to produce abnormal sound how to do? 1. Synchronous belt is not parallel, resulting in friction and abnormal sound. The solution is to adjust the motor so that the synchronous pulley on the spindle is parallel to the synchronous pulley on the worm shaft. 2. The reduction box is short of oil, resulting in increased friction and noise. The condition of lubricating oil should be checked regularly. 3. Slight friction between the turntable and the baffle plate (feeder) produces noise. The solution is to adjust the gap between the baffle plate (feeder) and the turntable; 4. If individual bearings are short of oil or damaged, lubricating oil should be applied or damaged bearings should be replaced; 5. The punch rod plug is not flexible in punching and rotation. The solution is to press the tablet room regular clearance, cleaning the rod.

Performance test of tablet press Test 1: check whether the connection of electrical and vacuum dust removal meets the requirements, and the lubrication of each part must meet the requirements. Check the die according to the die quality standard and install the die according to the instruction. Turn the hand wheel to rotate the table 2-3 times to make sure that the middle die and the regulating wheel can slide flexibly without collision and hard rubbing. Safety protection device, hopper installation meets the requirements, emergency brake system should be sensitive and reliable. Check the motor steering, do not reverse, and confirm that installation validation has been performed and approved. Test 2: No load operation for 60 minutes, noise no more than 82dB (A). All connectors and fasteners are connected reliably without loosening. Smooth operation, no abnormal vibration and impact sound. Clutch and gearwheel adjust flexibly and reliably, and position correctl

Appearance inspection of tablet press Equipment Appearance Inspection Verification method: carefully check the appearance of each component of the equipment.

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
