The above patent documents represent the mainstream of flat die-cutting equipment. However, from the die-cutting equipment disclosed in the above patent documents, it is not difficult to find that the existing die-cutting equipment has a common feature, that is, each has an eccentric shaft, thereby Forming a punching motion, which is essentially a crank slider mechanism, the motor is connected to the eccentric shaft through a speed reduction mechanism, and the eccentric portion of the eccentric shaft drives the connecting rod to form a reciprocating motion of the movable mold base. Because the motor rotates at a constant speed during operation, the reciprocating motion of the existing die-cutting equipment movable mold base and the time axis constitute a symmetrical motion. In order to realize continuous processing, the existing die-cutting equipment has a set of pulling machine. For the small-format (the length of the finger-shaped seat in the drawing direction is less than 500mm), the above-mentioned sinusoidal symmetrical curve motion has basically no problem. The pulling action is completed during the return time of the movable mold base, but for the large-format (the length of the mold base in the drawing direction is greater than or equal to 500 mm), the die cutting equipment has a relatively long absolute time of pulling, if the pulling time is To determine the return time of the movable mold base, the return time of the movable mold base will be longer, which will result in waste of time and low production efficiency; sometimes it is impossible to complete the die cutting process because the movable mold base moves according to the sinusoidal symmetrical curve. If the return time of the movable mold base is relatively long, the punching time of the movable mold base is also necessarily long. When the punching linear speed is less than the limit value, the die cutting processing cannot be completed.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a diagram showing the relationship between the motion trajectory and time of a conventional symmetrical motion based die cutting machine transmission system.

Figure 3 is a schematic diagram of a first embodiment of the present invention.

Figure 4 is a schematic diagram of a second embodiment of the present invention. EMBODIMENTS OF THE INVENTION The present invention will be described in detail below with reference to the accompanying drawings. Referring to FIG. 1 and FIG. 2, FIG. 1 is a relationship diagram of a motion path of a conventional die-cutting machine and time, and FIG. 2 is a relationship diagram of an ideal die-cutting machine motion trajectory and time in large-format machining. In the figure, LT1 represents the pull time, LT2 represents the pause time, CT1 represents the punch time, CT2 represents the return time, and CT3 represents the pause time. In the conventional die-cutting machine, the motion curve is a symmetric sinusoid. As can be seen from Fig. 1, the pulling time LT1 is equal to the punching time CT1 and is equal to half of the stroke period Τ. In any case, the die-cutting machine must first meet the requirements of the pull material on time, otherwise there will be defects such as broken material and deformation of the material being processed. Therefore, when the pulling time is insufficient, the pulling time is actively increased. As a result, the stroke period is multiplied (T=2xLTl), and the punching time is correspondingly increased (CT1=LT1), which leads to produce The decrease in efficiency, on the other hand, when the punching time CT1 increases beyond a certain limit, the material to be processed cannot be cut through or the cut is too rough due to the too low punching speed. The ideal die-cutting machine trajectory in large-format machining, the time of each stroke can be actively distributed, especially an intermittent time CT3 can be set in a punching cycle for waiting for pulling. It can be seen from Fig. 2 that in the ideal state, one stroke period T is equal to the punching time CT1 plus the pulling time LT1, and the feeding time is absolutely impossible to die-cut. Therefore, the stroke period 1 = (11+1^1 is The minimum stroke period is satisfied under large-format processing conditions.
