Description

Technical Field

[0001] This utility model relates to the field of paper and plastic, and in particular to a paper and plastic packaging component for a water heater. Background Technology

[0002] Pulp molding is a three-dimensional papermaking technology. It uses waste paper as raw material, shaping it into specific paper products using special molds on a molding machine. It has four major advantages: the raw material is waste paper, including cardboard, waste corrugated cardboard, and waste white paper, with a wide range of sources; the manufacturing process involves pulping, adsorption molding, drying, and setting, making it environmentally friendly; it can be recycled and reused; and it is smaller in volume than foamed plastics, can be stacked, and is convenient for transportation. Besides being used for lunch boxes and tableware, pulp molding is increasingly used for industrial cushioning packaging, and its development is very rapid. Pulp molding products are a rapidly growing new packaging material in recent years and are an excellent substitute for wood. The manufacturing process for pulp molding products involves: raw material pulping – batching – molding – drying – setting. Because a large amount of moisture (approximately 55-60%) remains on the workpiece after molding, the final product has a moisture content of 12-14%. Therefore, during the drying process, about half of the workpiece's weight in moisture must be removed. This moisture must be removed entirely by absorbing heat and turning into water vapor. Due to the phase change that occurs during the drying process, energy consumption is very high, making pulp molding a high-energy-consuming product.

[0003] Publication number CN221820754U discloses a water heater packaging structure. This packaging structure includes an upper pad, a lower pad, and at least two intermediate pads. The upper pad is placed on top of the water heater. The lower pad is placed at the bottom of the water heater. The intermediate pads are annular structures, and at least two intermediate pads are spaced apart and nested on the water heater between the upper and lower pads. A plastic sealing film is used to encapsulate the water heater packaged with the upper pad, lower pad, and at least two intermediate pads. The plastic sealing film is used to encapsulate the water heater packaged with the upper pad, lower pad, first intermediate pad, and second intermediate pad.

[0004] Publication No. CN219340440U discloses a water heater packaging structure and assembly. The water heater packaging structure includes an upper pad, a middle pad, and a lower pad. The upper pad has a first groove, into which a first end of the water heater is installed. The middle pad has a through hole, into which the water heater is inserted. The lower pad has a second groove, into which a second end of the water heater is installed. In a plane perpendicular to a first direction, the projections of the upper, middle, and lower pads coincide. The water heater includes a casing with a first wall-mounted bracket, the extension direction of which is inclined to the sidewall of the upper pad. This application allows for a reduction in the sidewall thickness of the upper, middle, and lower pads, thereby reducing the size and cost of the water heater packaging structure.

[0005] In comparison with the aforementioned documents, the existing overall packaging structure for water heaters is found to be costly, lacking in impact resistance and pressure resistance. Utility Model Content

[0010] The end-mounted paper-plastic body has a side-end center protection block at the center of its bottom surface.

[0011] The beneficial effects of this utility model are as follows: The water heater packaging structure provided by this utility model uses a paper-plastic molded packaging structure at both ends and the axial side of the water heater for fixed transportation. This protects the water heater from collisions during production and transportation, preventing damage. The two-piece paper-plastic molded end packaging structure, the middle paper-plastic packaging structure, and the supporting structure within them all protect various parts of the water heater, preventing deformation and ensuring effective protection.
