Description

Technical Field

[0001] The utility model relates to the technical field of honeycomb paper stretching machines, in particular to a honeycomb paper stretching machine with convenient material roller replacement. Background Art

[0002] Honeycomb paper is made according to the principle of natural honeycomb structure. It is made by gluing corrugated paper into countless hollow three-dimensional regular hexagons to form an integral load-bearing member - paper core, and gluing surface paper on both sides to form a new type of sandwich structure environmentally friendly and energy-saving material.

[0003] During the processing of the honeycomb paper core, in order to ensure that the honeycomb paper core maintains a regular hexagonal structure when it is bonded to the panel, a stretching forming machine is required to stretch the honeycomb paper core, and the honeycomb paper stock roller is used to feed the honeycomb paper stretching machine. The existing honeycomb paper stock roller needs to be replaced with a new honeycomb paper roll after the honeycomb paper roll is used up. In order to ensure stable operation, some honeycomb paper stock rollers are detachably fixed on the mounting frame at both ends. When replacing a new honeycomb paper roll, the honeycomb paper stock roller needs to be removed. After the replacement is completed, the honeycomb paper stock roller needs to be reset and installed, which is a cumbersome operation. Utility Model Content
