First, when the die cutting pressure changes, the position of the left and right claw block and gear plate can be adjusted, the claw block moves upward, and the cutting force increases (each claw block moves a tooth, the change in the distance between the two faces is about 0.1mm), generally only one tooth is moved at a time. When the position of the claw block on the gear is at the top of the last tooth, it should be considered to replace the new gear eccentric sleeve and the offset eccentric sleeve. The following methods can also be used to adjust: loosen the screw, so that the tooth shape adjustment plate is removed from the gear eccentric sleeve, and use the gear plate to rotate the gear to the back of the machine (note: the number of teeth on both sides should be equal, and no more than three teeth can be rotated at a time). Install the tooth adjustment plate, tighten the screw, adjust the claw block to the first tooth, see the number of cutting force, the effect is not ideal, can be adjusted again, but should pay attention to the number of teeth of the gear eccentric sleeve rotation, should be less than the number of teeth of the first rotation. When the left or right pressure is small, this method can also be used, that is, which side of the pressure is small, adjust the eccentric gear sleeve on the other side, and return the claw block to 1-2 teeth when testing.
2. When the upward and downward pressure deviation occurs, loosen the screws fastening the hook pad and the adjusting block of the pressure plate, increase the thickness of the gasket at the hook pad, and reduce the thickness of the gasket at the adjusting block of the pressure plate, and increase the upper pressure of the working face; Conversely, the lower pressure increases.
Third, the reasons for the reduction of die cutting pressure are:
(1) Big loose belt. It should be properly adjusted to make it properly relaxed.
(2) The friction surface of the clutch is mistakenly injected with oil or grease. Should be unloaded, clean with gasoline, wire brush; The friction surface is slipping due to wear and should be trimmed.
(3) The brake gap is too small and is often in the braking state. It should be adjusted in time so that the gap reaches 0.8-1.5mm.
(4) Due to the lack of oil, resulting in the burning of the bearing and the phenomenon of holding the shaft.
(5) The input voltage should be normal, the transformer, rectifier, relay, contactor work normally, the contacts are intact without ablation, the connecting wire head should be firm, the carbon brush and the slip ring exchange contact is good, otherwise, it will reduce the die cutting pressure.
