摘要

A drying device for synthetic leather with ultrafine fibers is characterized in that it comprises a housing (100), an unwinding roller (121), a winding roller (122), a first guide roller (13), a second guide roller (14), a third guide roller (15 ), a fourth guide roller (16), a heating box (17), a first heating element (19), a second heating element (20), a first fan (21), a first air duct (22), a second fan (23) and The housing (100) is provided with an inlet opening (101), an outlet opening (102) and a first opening (104). The housing (100) is provided with a drive device for driving the rotation of the unwinding roller (121) and the winding roller (122). The unwinding roller (121) and the winding roller (122) are arranged side by side from top to bottom, and the unwinding roller (121) is located at the inlet opening (101). The take-up roll (122) is located at the outlet opening (102). The first guide roller (13), the second guide roller (14), the third guide roller (15) and the fourth guide roller (16) are rotatably arranged on the inner wall of the housing (100). The heating box (17), the first fan (21) and the second fan (23) are all arranged on the inner wall of the housing (100). The heater box (17) is located at the first opening (104). The heater box (17) is provided with a second air inlet (171), a first air outlet (172) and a second air outlet (173). The first heating element (19) and the second heating element (20) are arranged on the inner wall of the heating box (17). The first air duct (22) is a Y-shaped cylinder structure. The first air guide tube (22) is provided with one air inlet end and two air outlet ends. The air inlet end of the first air duct (22) is connected to the air outlet end of the first fan (21). The two air outlet ends of the first air guide tube (22) blow in the direction of a gradual inclination from the bottom up or from the top down. The air inlet end of the first fan (21) is connected to the heating box (17) via the first air outlet (172). The second air duct (24) is an L-shaped cylinder structure. The second air guide tube (24) is provided with an air inlet end and an air outlet end. The air inlet end of the second air guide tube (24) is connected to the air outlet end of the second fan (23). The air outlet end of the second air guide tube (24) is arranged in the vertical direction between the two air outlet ends of the first air guide tube (22). The blowing direction of the air outlet end of the second air guide tube (24) is in the horizontal direction. The air inlet end of the second fan (23) is connected to the heating box (17) via the second air outlet (173).
