paper angle edge board protector is a specialized equipment used for producing paper corner protectors, which can process paper into paper corner protectors with certain strength and shape through a specific process flow. Paper corner protectors are commonly used in the packaging industry to enhance the edge strength and overall stability of packaging boxes.

Main components and working principle

The main components of an automatic angle corner edge protector machine include paper guiding, gluing, forming, cutting, and automatic stacking devices. The working principle is roughly as follows:

Paper guiding and gluing: The paper enters the machine through the paper guiding device, and then passes through the gluing device to evenly apply glue on the edges of the paper.

Molding: The paper that has been glued enters the molding section, which is usually composed of several sets of “V” – shaped pressure rollers that cooperate with each other to press the paper into a right angle shape or other desired shape.

Cutting: The formed paper corner protector is cut by a “V” – shaped die driven by a cylinder through a cutting device, ensuring that the length of the paper corner meets the requirements.

Automatic stacking: The cut paper corner protectors automatically fall into the collection area, ready for the next step of packaging or transportation.

Modern edge protector making machine may integrate CNC technology, improving the accuracy and production efficiency of the equipment. For example, some high-speed CNC paper corner protectors adopt advanced support rods, tool holders, irregular wheels, and connecting rod designs to achieve fast and precise cutting and forming. In addition, in order to adapt to composite cardboard of different thicknesses, some paper corner protectors are equipped with edge wrapping adjustment components. By rotating the threaded connection between the screw and the sliding platform, the distance between the sliding pressure wheel and the support wheel can be adjusted to achieve adaptive adjustment function.
