At present, washing machine packaging mostly uses plastic cushioning materials, which cannot be regenerated, nor is it degraded, and the volume is large, which makes it difficult to recycle and transport. With the continuous enhancement of people's awareness of environmental protection, foam plastic cushioning and lining can no longer adapt to the packaging requirements of low-carbon environmental protection. Most of the paper cushioning pads used on the market are made of honeycomb cardboard stamped by special stamping equipment and molds. However, the lateral pressure strength of single honeycomb paperboard products decreases with the increase of aperture, and the washing machine product cannot be reliably fixed, and this paper-based buffer packaging liner is not beautiful, the waterproof performance is also poor, and it is easy to tilt for a long time stack storage.

In view of the application status of paper cushioning liners, and according to the packaging requirements of washing machine products, by combining corrugated cardboard and honeycomb cardboard, and aiming at industrial production, a new type of paper cushioning packaging line is designed, and its mechanized production line scheme is proposed.

1 The overall structure and performance requirements of the liner 1.1 The overall structure is aimed at the shortage of paper cushioning pads on the market at present, taking the form of corrugated cardboard and honeycomb cardboard, paper cushioning pads include a pad skeleton and a buffer body bonded to the pad skeleton, plastic parts are bonded and embedded in the padding bottom plate, wherein the pad skeleton is folded by corrugated cardboard, and the buffer body is bonded by honeycomb cardboard. This product uses corrugated cardboard as the base, positioning plate and insert plate, block and strip honeycomb components as cushioning materials, and the middle is embedded in the block bee board through plastic parts, which greatly improves the cushioning strength and seismic resistance of the paper cushioning pad. And the use of favorable mechanized production of the structure design, easy to mechanized production. See paper cushioning liner.

Honeycomb bottom plate right plate; 7. Plastic parts; 8. Honeycomb bottom plate backboard paper buffer packaging liner can be seen, the buffer packaging liner is mainly composed of corrugated cardboard, honeycomb board and plastic parts, the main molding method is viscose fixing, embedding and folding. The white latex adhesive fixing between the cut corrugated cardboard and the honeycomb cardboard, the embedding and bonding between the plastic parts and the honeycomb baseplate are fixed, and the white latex bonding fixation between the honeycomb paper plates and strips.
