The Versatility of Rotary Tablet Press PHARMA Manufacturer
and adjustment of rotary tablet presses
1. Preparation work before mold equipment: remove the hopper and feeder. Open the right door and turn the handwheel to clean the working surface of the turntable, the mold hole and the mold of the required equipment. Rotate the pressure to adjust the wheel to minimize pressure. Remove the lower punch loading and unloading rails.
2. Medium-sized mold equipment: Rotate the middle mold fastening screw on the turntable about 1 mm from the outer circumference of the turntable. Be careful not to touch parts such as the powder nozzle. Do not touch the screw heads when loading into the middle mold. should. Medium-sized devices are tight and should sit steady. Punch the rod into the upper punch and go in silently. After the middle mold enters the die hole, the plane is not higher than the plane of the turntable, and then the screw is tightened.
3. for the upper punch: first remove the tongue, then insert the upper punch into the hole, rotate the punch with your thumb and forefinger, check the elasticity of the head, make the middle mold slide up and down, and it is qualified if there is no jamming . Then roll the handwheel onto the punched neck to contact the parallel rails. The upper punch is fully loaded and the tongue installed.
4. under the punch press: install the equipment under the loading and unloading guide rails according to the method of punching up.
5. Typing operation: After installing a complete set of molds, turn the handwheel and the turntable will rotate for 2 circles. Study the upper punch and the lower punch to enter the middle die hole and work on the track. No jams and collisions are acceptable. It should be noted that the highest point (that is, the outlet) should be located 0.1 to 0.3 mm above the working surface of the turret. Close all doors, start the motor, idle for 2 minutes, and use it after the operation is stable.
Second, other adjustments of the rotary tablet press:
1. and adjustment of the feeder: install the feeder on the support frame of the feeder, then tighten the knurled screw, and then adjust the adjustment screw so that the gap between the bottom surface of the feeder and the turntable table is 0.05- 0.1 mm. Tighten the knurled screw and adjust the height of the scraper so that the bottom plane is flush with the turret working surface. Tighten the screws.
2. Regulating filling: Filling inference equipment on the right side of the front of the machine, the handwheel control handwheel has an indicator mark. When the handwheel is turned clockwise, the fill volume decreases and vice versa. When conditioning, pay attention to the particles in the feeder, and adjust the pressure so that the film has a satisfactory weighing hardness. 3. Tablet thickness (pressure) adjustment: The tablet thickness (pressure) adjustment is controlled by the device on the left side of the front of the adjustment handwheel, and there are indications on the side of the handwheel.
When the handwheel is turned counterclockwise, the tablet thickness decreases (increased pressure) and the tablet thickness increases (decreased pressure). After setting the filling amount, check the thickness and hardness of the tablet, and then make appropriate fine-tuning until it is qualified. 4. Adjust the amount of powder: When adjusting the filling amount, adjust the amount of particles. First, loosen the screws on the side of the bucket frame, and then turn the adjusting screw on the bucket frame to adjust the distance between the hopper opening and the working surface of the turret. The interval between inspection and general storage of pellets in the feed port is usually not acceptable. After adjustment, tighten the screws.
