Description

Technical Field

[0001] The utility model mainly relates to the technical field of cardboard edge wrapping processing equipment, in particular to an edge locking mechanism used for cardboard edge wrapping. Background Art

[0002] Cardboard, also known as board paper, is mainly corrugated cardboard or honeycomb cardboard. It is a thick paper sheet made of various pulps and fibers interwoven with each other. Its main raw material is recycled cardboard, and the thickness can be high or low. It is mainly used in packaging boxes, packaging or cushioning of large equipment, but the stiffness and burst resistance of this cardboard are relatively low.

[0003] Honeycomb paperboard is made according to the principle of natural honeycomb structure. It is a new type of sandwich structure environmentally friendly and energy-saving material made by connecting corrugated paper into countless hollow three-dimensional regular hexagons by gluing to form an integral force-bearing member - paper core, and gluing surface paper on both sides. The processing process of honeycomb paperboard mainly includes five units, namely, paper loading unit, honeycomb paper core stretching and shaping unit, honeycomb paper core gluing unit, honeycomb paperboard composite unit and honeycomb paperboard cutting unit. In order to prevent the side of honeycomb paperboard from wrinkling and damage, it is usually wrapped with transparent tape after cutting. After the tape is gradually squeezed on the side of the paperboard by the edge roller, there is a certain gap between the contact surface of the paperboard and the edge roller, and the paperboard will vibrate up and down slightly during the transmission process, which causes the tape to sometimes not completely adhere to the side edge of the paperboard, and bubbles may appear. The bonding is not strong, resulting in falling off in the later stage, causing wrinkles on the side of the paperboard, affecting the service life. Utility Model Content
