Installation of rubber pads
Note: Due to the high cost of the rubber pads, please use them with care.
a. Use light die-cutting pressure whenever possible. During trial die-cutting, cut through 80% first. This will allow for smooth die-cutting and waste removal at high speeds.
b. Frequently adjust the position of the rubber pads, starting from the center and working outwards. After adjustment, perform appropriate grinding.
Speed Difference Compensation Device ±
This machine adopts a precision tracking-type "set-controlled" adjustment, allowing the speed of the rubber pad roller relative to the template roller to be increased or decreased. This achieves segmented speed difference compensation to compensate for die-cutting size errors caused by the decrease in linear velocity due to rubber pad wear. The adjustable range is approximately ±1% of the roller circumference. The larger the cardboard...
The larger the adjustment range, the smaller the segment size (based on the 4th segment "0"). The smaller the segment size, the smaller the die-cutting size; the larger the segment size, the larger the die-cutting size.
Regarding the correct use of the speed difference compensation mechanism on the VRIDA series die-cutting machine:
When the die-cutting pad wears down, its diameter inevitably decreases, causing a discrepancy in the linear velocity of the surface contact between the cutter roller and the pad roller, resulting in changes in the die-cutting dimensions. The essence of speed difference compensation is to ensure that the linear velocities of the upper and lower rollers are consistent.
The compensation principle of the "precision setting compensation mechanism" is to use an encoder to track the speed of the die-cutting roller, outputting a signal to a variable frequency motor. The variable frequency motor outputs power to a specially designed planetary speed change mechanism, thereby changing the operating speed of the pad roller and achieving synchronization with the die-cutting roller speed. The maximum range is ±1% of the entire die-cutting blade circumference. For example, if the length of the arc blade is 400 mm, then when NO.1 (section D, first segment) is selected, the actual die-cutting dimension is approximately 396 mm. If NO.7 (section 7) is selected, the actual die-cutting dimension is approximately 404 mm. However, if the middle section (NO.4) is selected, the actual die-cutting dimension remains 400 mm.
