Cooling device of hot air consolidation equipment

Abstract

The utility model provides a cooling device of hot air consolidation equipment, the cooling device is arranged in a hot melting box and comprises an air cooling mechanism, an air supply cavity and an opening and closing mechanism, a rotary screen assembly and a hot air assembly are arranged in the hot melting box, different spun-bonded fabrics to be hot-melted are introduced into the hot melting box, are attached to and bypass the rotary screen assembly, are hot-melted and consolidated and then are led out from the top of a discharge port, and the hot air assembly is arranged in the hot melting box. The hot air assembly is configured to provide hot air for hot melting; the air cooling mechanism is arranged outside the hot melting box, the air supply cavity is arranged obliquely above the rotary screen assembly and is close to the discharge port, the air inlet end of the air supply cavity is communicated with the air cooling mechanism, the air cooling mechanism is configured to supply air into the air supply cavity, the opening and closing mechanism is used for controlling the air exhaust end of the air supply cavity to be opened and closed, and the air exhaust end of the air supply cavity is arranged towards the rotary screen assembly; the air exhaust end of the air supply cavity is controlled to be opened through the opening and closing mechanism, so that air in the air supply cavity is conveyed towards the rotary screen assembly, then air cooling is carried out on cloth subjected to hot melting on the surface of the rotary screen assembly, the cloth cooling speed is increased, and the product production efficiency is improved.
