1. A pulp molded product line with roll forming function, comprising:
a pulp suction device;
a hot pressing assembly, configured 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, configured to perform edge cutting on the hot pressed pulp molded product obtained after the hot pressing of the hot pressing assembly to obtain an unrolled pulp molded product; and
a rolling device, configured to perform radially inwards rolling on the unrolled pulp molded product obtained after the edge cutting of the edge cutting device to obtain a pulp molded product;
wherein an annular convex buckle is formed on an inner wall of the pulp molded product obtained after the rolling of the rolling device, and an annular rolling groove corresponding to the annular convex buckle is formed on an outer wall of the pulp molded product;
wherein the rolling device comprises:
a loading unit, configured to load and convey the unrolled pulp molded product;
a rolling unit, comprising a horizontal rotating table; wherein at least one translatable rolling wheel is horizontally slidably connected to an upper surface of the horizontal rotating table, the at least one translatable rolling wheel is connected to a translation driving mechanism and a rotation driving mechanism, the upper surface of the horizontal rotating table is rotatably connected to two rolling moving dies located at a periphery of each translatable rolling wheel and symmetrically distributed with the translatable rolling wheel as a center, a rotation direction of each of the two rolling moving dies is opposite to a rotation direction of the translatable rolling wheel, and rotation speeds of the rolling moving die and the translatable rolling wheel are the same; each rolling moving die corresponds to a rotary pressing-down assembly, each rolling moving die corresponds to a rotary driving mechanism, the rotary driving mechanism is configured to drive the rolling moving die to rotate, the translatable rolling wheel is configured to move close to the rolling moving die, thereby to radially inwards roll the unrolled pulp molded product, and a next unrolled pulp molded product is placed on another rolling moving die; and
a take-and-place unit, configured to place the unrolled pulp molded product conveyed by the loading unit on the rolling moving die, and obtain and transfer the rolled pulp molded product out of the rolling unit; and
wherein the pulp suction device and the hot pressing assembly are used to transfer the pulp through a first robot; and the edge cutting device and the rolling device are used to transfer the unrolled pulp molded product through a second robot.
