Description

Technical Field

[0001] The present invention relates to the technical field of pulp molding, and in particular to a constant temperature drying line integrated machine. Background Art

[0002] Pulp molding, also known as three-dimensional papermaking, uses pulp as raw material and forms a molded product into a specific shape using a special mold on a molding machine. Pulp molding offers the advantages of renewable raw materials, easy transportation, and environmental friendliness. It is primarily used for applications such as lunch boxes, tableware, and product trays. The production process includes pulping, adsorption molding, and drying to finalize the shape.

[0003] After searching, the Chinese invention patent application with patent application number CN202310097346.7 discloses a pulp molding drying line, including a mold-shifting manipulator, a drying group unit, a turning machine, a conveying track and a mobile trolley; the number of drying group units is several, and multiple groups of drying group units are arranged along the front-to-back direction. Two adjacent drying group units can be detachably connected to each other, and the rear side of the drying group unit at the rear end is equipped with a turning machine, and the front side of the drying group unit at the front end is equipped with a mold-shifting manipulator, and the front side of the mold-shifting manipulator is equipped with a turning machine. The mold-shifting manipulator, the drying group unit and the turning machine are respectively provided with conveying tracks, and the conveying tracks are equipped with a mobile trolley. This pulp molding drying line solves the problem of uneven drying and large deformation of the product caused by the drying method of the prior art that uses hot air to flow on the surface of the pulp molded product.

[0004] Another example is a Chinese utility model patent application numbered CN202122669171.1, which discloses a pulp molding drying production line comprising a conveyor frame, support legs, driven rollers, a drive motor, a driving roller, a conveyor belt, an adjustable dustproof lighting plate structure, an anti-heat-dissipating drying box structure, and an automatic marking rod structure. The four corners of the bottom of the conveyor frame are bolted to support legs; the right side of the conveyor frame is connected to a driven roller; and the left side of the front of the conveyor frame is bolted to a drive motor. The utility model's arrangement of guide plates, dustproof plates, U-shaped brackets, fastening bolts, uprights, and lighting tubes facilitates dust prevention and is adjustable for easy operation. The lighting tubes enhance lighting functionality and allow inspection of the pulp film to ensure its integrity.

[0005] Although the existing pulp molding drying line can meet basic usage requirements, it adopts a multi-fan and multi-burner structure, cannot recycle waste heat, and has high energy consumption. Summary of the Invention
