Abstract
A pulp molded product line with roll forming function includes a pulp suction device, a hot pressing assembly used to perform hot pressing on a pulp sucked by the pulp suction device to obtain a hot pressed pulp molded product, an edge cutting device used to perform edge cutting on the hot pressed pulp molded product to obtain an unrolled pulp molded product; and a rolling device used to perform radially inwards rolling on the unrolled pulp molded product to obtain a pulp molded product. The advantages of the pulp molded product line with roll forming function are that the waste problem of inconsistent material thickness by rolling can be solved, the raw materials can be saved and the production and processing efficiency can be improved.
