Clean Room Tablet Pressing Equipment
Tablet press is a solid preparation equipment that compresses dry granular or powdery materials into tablets through a die. The adjustable parameters of tablet quality are: main and pre-compressed tablet thickness and filling amount. Under the condition of a certain filling amount, main and pre-compressed tablet thickness determine main and pre-compression pressure, that is, tablet hardness; filling depth determines quality. Installation area and process layout: The cleanliness of the dust-free pharmaceutical cleanroom is Class D; the main equipment includes tablet presses, vacuum cleaners, tablet screening machines, metal detectors, elevators, etc.; 70%, the highest altitude is 1500m.
Before the operation of the tablet press, clean the machine and install the punches and middle dies required for production correctly, and then set it according to ordinary production, so as to find the main pressure value suitable for production; set it according to the empirical value before starting the machine , after starting the machine, the operator needs to reduce the thickness of the sheet; turn the handwheel before production to ensure that the rotation of the turret does not interfere with other parts, and when installing a single piece of waste rejection and discharge chute, ensure that the discharge chute does not contact the turret; during installation When moulding, apply a very small amount of lubricating oil on the surface of the middle mould to facilitate the insertion of the middle mould into the hole. After placing the middle mould into the middle mould hole, tap the middle mould with the middle mould installation tool to ensure that the middle mould is installed in the designated position; When adjusting the speed of the machine, in order to ensure product quality and avoid product waste, gradually increase the speed, and set the interval at 10,000 or 20,000. It is recommended that the increase should not exceed 50,000 each time, and the pressure and feeding shoe speed should be corrected if necessary; Use a vacuum cleaner, a brush and a rag for cleaning, and it is strictly forbidden to use compressed air for dust cleaning; the plexiglass and silica gel of the hopper are not allowed to be cleaned and disinfected with alcohol; the filter element of the vacuum cleaner can only be cleaned with a vacuum cleaner and compressed air, and washing with water will reduce the service life; all parts When dismantling, it should be handled with care, placed neatly, and it is forbidden to stack them on top of each other. After the mold is cleaned, apply anti-rust oil in time. Zhongjing Global Purification can provide consulting, planning, design, construction, installation, transformation and other supporting services for dust-free workshops and dust-free workshops.
The tablet press in the dust-free workshop needs to be maintained every day. Clean the surface of the production area, clean the oil baffle ring or corrugated sleeve, check whether the main door electromagnet is normal, and check whether the waste removal hole is unobstructed. Weekly maintenance: whether the machine status light is normal, whether the emergency stop button is working properly, check whether the function of the feeding shoe is normal, clean the filter screen; check whether there is oil leakage in the oil circuit, check whether the dust suction line is unblocked, and check the lubrication Check the oil pump level, add grease, check whether the oil scraper is damaged, check whether the top wire of the middle die is normal; check whether the limit value function of each parameter is normal, and check whether there is air leakage in the compressed gas pipeline. Monthly maintenance: check whether the fan works normally, check whether the oil level of the gear box is abnormal, check whether the belt of the main motor is properly tight, check whether the motor is running normally; check whether the surface of the pressure roller is smooth and not damaged, and whether the punch is abnormal, Whether the height difference between the bottom plate of the feeding shoe and the formwork surface in the brick tower is normal, the wear of the upper punching track and the lower punching; when the machine is not used for a long time due to factors such as pharmaceutical cleanroom environment and production plan, the surface of the machine parts should be treated with anti-rust treatment.
Common faults and solutions of tablet presses in dust-free workshops: Use a knife edge gauge and feeler gauge to check the height difference between the die table in the turret and the bottom plate of the feeding shoe, and the bottom of the feeding shoe is 0.05-0.1 higher than the die surface in the turret mm, if it is not within this range, adjust the three adjusting bolts under the bottom plate of the feeding shoe; use a feeler gauge to check that the distance between the over-tightening of the upper punch and the tail of the upper punch is 0.2-0.3mm, if it is not within this range, adjust the over-tightening of the upper punch Rotating bolts above; check with feeler gauge and 10mm sheet gauge, the end face of lower punch is 0.1-0.3mm higher than the table top of the middle die, if it is not within this range, adjust the ejection height; the installation of machine parts is completed, before starting the machine, it must be Turn the handwheel to make the machine brick tower rotate for a complete week and then start it up; the maintenance of the machine, such as the replacement of the transmission belt, the replacement or filling of the lubricating oil, the maintenance of the screen machine, the gold inspection machine, the vacuum cleaner, etc. Instructions are executed.
