In the corrugated packaging production process, the problems of scoring and creasing have always been regarded by most people in the industry as the most difficult problems to be solved by the printer and In-line. How can we improve the precision of the front end to ensure the quality of the back end printing and die-cutting, and to improve the actual production efficiency? In this video, Corrface comes to HENGLI to witness the launch of its brand new cutting-edge technology - intelligent new crawler-type creasing unit. This advanced technology is divided into a total of correcting group, scoring group, crawler-type creasing belt and clean edge die-cutting, which can realize the integration of printing, scoring, slotting and die-cutting.

The front correcting group adopts electronic correcting method, which can accurately detect the position of paper and accelerate the belt operation through servo motor to ensure the uniformity of paper feeding. The air-absorbing effect below the correcting group does not affect the printing surface, which can fully guarantee the consistency of the quality of the printed products.

The scoring is integrated with the printing process, eliminating the need for an additional scoring process. For the double E flute, which is most prone to bursting, there will be no bulging, thus reducing the phenomenon of paperboard cracking.

Before the emergence of Crawler-type creasing, most of the packaging enterprises generally use the pressing wheel for crease. Crawler-type straight line creasing adopts the overall force, which can be adapted to any material and flute shape of paperboard, solving the pain point of bulging, and solving the subsequent rough edge and different size.

The clean edge die-cutting passes through the pressure-free paper feeding to the die-cutting unit, leaving no front and rear edges after die-cutting, which can achieve the production effect of how large the paperboard is and how large the carton is. Each paperboard can save about 2 centimeters of edge, and more than 20 cartons can save the materials of one carton, which can help companies achieve a net profit growth of 2-4% only by reducing initial costs.

The precision of the front end tends to be perfect, so that the back end can realize the clean edge die-cutting without margins, which is also the most valuable core competitiveness of the whole set of equipment. At present, the actual running speed of this innovative equipment has reached 300m/minute and is constantly breaking through to 350m/minute. HENGLI said that the durability and noise of the equipment will be further tested in the future to provide more benefits to customers' actual production.
