Do You Know About Die Cutting Anvil Cover?

In the production process of corrugated cardboard boxes line, die-cutting anvil cover play a crucial role.

One of the factors affecting production efficiency and quality, namely the issue of soft seams, is attributed to the structure of the die-cutting anvil cover.

The die-cutting anvil cover is fixed in the groove of the die-cutting roller. If the locking part is entirely made of polyurethane material, the groove lacks the support of metal material. When die-cutting reaches this part, the polyurethane in the groove will sag, forming a soft cut. To ensure smooth production, greater die-cutting pressure is required at this part, which may lead to over-cutting at other parts. This affects the compressive strength and quality of the final finished carton.

From the production results, it is evident that the structure of the die-cutting rubber anvil cover plays a crucial role in both die-cutting efficiency and waste removal effectiveness!

Buckle Type of Anvil Cover

The common main structures of die-cutting anvil cover are divided into straight steel structure, horse tooth buckle structure, and wavy interface.

Among these three structures, the steel structure demonstrates the best practical performance.

The notch position of the die-cutting anvil cover with a horse tooth buckle structure is filled with polyurethane. Under the same die-cutting pressure or the same die-cutting gap, it is prone to partial incomplete cutting, or intermittent incomplete cutting at the notch position. If complete cutting is required, greater pressure is needed to facilitate production.

The die-cutting rubber pad with wavy joints not only has the defect of soft seams, but also is prone to wavy misalignment during installation, resulting in gaps at the joint position and poor cutting and waste removal due to the absence of cutting teeth.

The horse tooth buckle structure and wavy interface are prone to structural issues, which can lead to delays in the construction schedule and affect the final product's appearance.
