Introduction to the use of single punching machine

1. Read the instructions carefully before using the machine for the first time before using it.

2. The machine can only be operated in a certain direction (see the arrow on the handwheel or the protective cover), and can not be reversed to avoid damage to the machine. Pay special attention to the adjustment of the tablet, do not neglect.

3. Belt tension adjustment: Adjust by two adjusting nuts on the electromechanical bottom plate. Pay attention to the lock after adjustment.

4. When the power is applied without power supply, the V-belt should be removed to reduce the resistance and wear. But don't remove the big pulley, because the large pulley has the effect of the flywheel.

5. When turning on the electric tablet, the rotating handle on the handwheel must be pulled down to avoid injury when running.

6. Regardless of manual pressing or electric pressing, the upper punching rod should be in the raised position and then restarted before starting. If the upper punch is started in the lowered position, the medium-molded piece is entered just after the start of the start. At this time, since the rotation speed of the machine has not risen and the inertia is small, the top car is likely to occur. (That is, after the upper punch enters the middle mold, it is "top dead" due to the resistance of the tablet, so that the machine stops running. When the top car is loaded, the machine is often damaged or the motor is damaged.)

7. Disposal methods after the top car (1) When the car is in the state of electric pressing, the power should be turned off immediately to avoid burning the motor.

(2) When the top car is light, you can use the hand to turn the handwheel to make the upper punch pass the "dead point" (but not reversed, so that the feeder does not repeat the feeding, resulting in a more serious top car).

(3) When the vehicle is in serious position, loosen the connecting rod lock nut, turn the upper punch rod to raise it to reduce the pressure, and then turn the hand wheel to push the medicine out. Then re-adjust the hardness of the tablets.

8. During the tableting process, the quality of the tablets (sheet weight, hardness, surface finish, etc.) should be checked frequently, and adjusted in time. 9. The batching granulation process before tableting has a great influence on the tableting. For example, the formulation of granules such as medicinal materials and slips, fillers, binders, etc. (the condition of the powder, the tightness of the granules, the proportion of the granules, the water content, etc.) directly affect the quality of the tablets. And often due to improper granulation of ingredients, it is impossible to form a piece or even damage the machine. Therefore, the machine cannot be used for tableting semi-solid or moist or non-granular fine powder. In the use, if the pressure has been adjusted to be quite large, it is still not pressed into pieces or pressed into pieces but appears too loose, layering, debris, pitting, falling powder and so on. It is necessary to find out the reasons and solve them from the aspects of ingredients. Do not blindly adjust to increase the pressure, and even damage the machine. In addition, although the hardness of the tablets extruded by some medicines is not large, it has a certain degree of toughness, and it is not bad for it to fall into the ground (usually it can be broken from the height of 1-1.2 meters on the ground), so it should be To meet the requirements of transportation and storage, do not focus on hardness alone, so as to avoid excessive pressure on the tablet and damage the machine.
