[0002] Tear-resistant corrugated cardboard is a type of corrugated cardboard with high strength and tear resistance, and is typically used in situations where it needs to withstand high tensile and tearing forces. This type of cardboard improves its tear resistance by adding one or more layers of tear-resistant material to the corrugated cardboard. Tear-resistant corrugated cardboard is widely used in logistics, transportation, and packaging, especially in situations where it needs to withstand heavy objects or frequent handling. The tear-resistant corrugated cardboard forming and pressing device is a device specially designed for the production of tear-resistant corrugated cardboard. Its core function is to achieve the forming and pressing of corrugated cardboard. Existing tear-resistant corrugated cardboard forming and pressing devices cannot accurately align the two layers of cardboard, resulting in deviations in the position of the two pressed cardboards, affecting their pressing accuracy. Utility Model Content
