Description

Technical Field

[0001] The present invention belongs to the field of die-cutting and stamping equipment, and particularly relates to an intelligent pressure compensation device for a die-cutting machine. Background Art

[0002] In the process of preparing packaging boxes, it is usually necessary to use a die-cutting machine to cut or indent various paper products. During the die-cutting process, the paper to be die-cut runs upward with the lower platform to the position of the die-cutting knife, and the paper to be die-cut is cut or indented under the action of pressure. However, during the production process, since the surface of the paper is not a completely flat plane, and the bottoms of each cutting knife (die-cutting knife) and each indentation line of the die-cutting plate cannot be completely in the same plane, this results in incomplete cutting or insufficient indentation in some areas of the cut paper, affecting the yield rate; in the existing die-cutting process, when pressure unevenness occurs, it is necessary to manually pull out the die-cutting plate and use special compensation paper to compensate the pressure at the place where the machine pressure is low, and then try to cut the paper again. If there is still a situation where the die-cutting is not in place, the above compensation operation needs to be repeated until the pressure in the entire die-cutting area is consistent. The operation is inconvenient, and the manual pressure compensation operation is limited by the personal experience of the operator;

[0003] Specifically, there are the following deficiencies:

[0004] 1. In the prior art, it is necessary to manually use compensation paper for pressure compensation, and the pressure compensation effect is limited by the personal experience of the operator;

[0127] S7. Pressure compensation detection; the controller judges whether all pressure compensation points have completed the pressure compensation according to the data transmitted by the controller. If there are other required positions, the controller will issue an instruction, and the coordinate adjustment mechanism B drives the electric adjustment mechanism C to move to the next pressure compensation position and re-execute the actions S4 - S6; if all positions have completed the pressure compensation, the coordinate moving device B moves the electric adjustment tool C to the coordinate origin;

[0128] S8. Start die-cutting; after the pressure compensation is completed, the paper is normally die-cut, and at the same time the controller reads whether the pressure at each position is normal. If there is an abnormality, it returns to the action S2 to re-perform the pressure compensation, otherwise, the machine performs normal die-cutting;

[0129] S9.

If the torque output by the pressure compensating motor C11 reaches the set value, it is determined that the fine-tuning mechanism A reaches the zero point, and the subsequent actions are continued. If the reverse action time exceeds the set value, the controller alarms and executes action S6;

[0138] T8: The pressure compensating motor C11 drives the locking tapered rod A2 to rotate according to the pressure compensation amount transmitted by the controller. The lower pressure head A14 extends to squeeze the die-cutting backplane E1, completing the single-position pressure compensation action;

[0139] T9: After the pressure compensation is completed, the unlocking cylinder C7 drives the unlocking rod C15 to move upward and disengages from the unlocking ejector rod A1. The tapered sleeve A6 re-clamps the locking tapered rod A2 under the action of the unlocking compression spring A7. The pneumatic chuck C10 cuts off the air supply and releases the locking tapered rod A2. The controller determines whether the unlocking cylinder C7 and the pneumatic chuck C10 time out. If there is no alarm, the subsequent actions are continued. Otherwise, it returns to action S6;

[0140] T10: The linear cylinder retracts, driving the electric adjustment mechanism C to rise, ensuring that the lower surface of the pneumatic chuck C10 is higher than the fine-tuning mechanism A. If there is no alarm, the single-point pressure compensation action is completed. Otherwise, it returns to action S6.
