Rotary tablet press equipment adjustment considerations

Rotary tablet press precautions and installation adjustments

　　First, the equipment and adjustment of the rotary tablet press:

　　1. Prepare the work before the mold equipment: Remove the hopper and feeder. Open the right door and roll the handwheel to clean the working surface of the turntable, the die hole and the mold of the required equipment. Rotate the pressure to adjust the wheel to minimize pressure. Remove the undershoot loading and unloading rails.

　　2. Medium-sized mold equipment: Rotate the intermediate mold fastening screw on the turntable about 1 mm from the outer circumference of the turntable. Be careful not to touch parts such as powder nozzles. Do not touch the screw head when loading the intermediate mold. should. Medium-sized equipment is tight and should be placed smoothly. Draw the rod into the upper punch and enter quietly. After the intermediate mold enters the die hole, the plane is not higher than the plane of the turntable, and then the screws are tightened.

　　3, the equipment of the upper punch: first remove the tongue, then puncture the upper punch into the hole, use the thumb and forefinger to rotate the punch, check the elasticity of the head, so that the intermediate mold slides up and down, no jamming phenomenon is qualified . Then roll the handwheel to the punched neck to contact the parallel rails. The upper punch is fully loaded and the tongue is installed.

　　4, the equipment under the punch: according to the method of the upper punch, the equipment is installed under the loading and unloading rail.

　　5. Typing operation: After loading the complete set of molds, rotate the handwheel and rotate the turntable for 2 weeks. The upper punch and the lower punch are studied to enter the intermediate die hole and work on the track. No jams and collisions are acceptable. It should be noted that the highest point (ie the exit) should be located 0.1 to 0.3 mm above the turret working surface. 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. Feeder equipment and adjustment: 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. Adjust the filling: Fill the inference device on the right side of the front of the machine, and the handwheel control handwheel has an indication mark. When the handwheel rotates clockwise, the amount of filling decreases and vice versa. When conditioning, pay attention to the particles in the feeder and adjust the pressure to give the film 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 hand wheel, and the side of the hand wheel is indicated.

　　When the hand wheel rotates counterclockwise, the tablet thickness decreases (pressure increases) and the tablet thickness increases (pressure decreases). After setting the filling amount, check the thickness and hardness of the tablet, and then perform appropriate fine adjustment 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 rotate the adjustment screws on the bucket frame to adjust the spacing between the hopper opening and the turret face. The spacing between the inspection and the general storage of the particles in the feed port is generally unacceptable. After adjustment, tighten the screws.
