Cast film drying equipment

Abstract

The invention discloses a casting film drying equipment, which comprises a frame, a main engine transmission mechanism and a casting mechanism for feeding materials. The main engine transmission mechanism includes a steel belt and a transmission device for driving the steel belt to run. The transmission device includes a motor, a driving drum and a driven drum, the casting mechanism is arranged at one end of the steel belt, and the outer coating of the steel belt is provided with a hot air circulation drying mechanism, and the hot air circulation The upper end of the drying mechanism is connected with at least one set of thermal energy conversion mechanism, and the thermal energy conversion mechanism includes a thermal energy collector, a fan, a heat exchanger and an exhaust pipe. The hot air circulation drying mechanism is connected, and the other end of the hot air circulation drying mechanism is connected to the exhaust pipe; realize the heat source generated by steam, electric heating box, electric heating rod or infrared rays, and the waste heat source of flue gas discharged from industrial boilers into hot air drying Dry features, low energy consumption, uniform and stable temperature, can bring greater profit margins to demand enterprises, accelerate the development of enterprises, and belong to environmental protection and energy-saving engineering projects.

Description

technical field [0001] The invention relates to the technical field of film casting and drying equipment, in particular to a casting film drying equipment. Background technique [0002] At present, most of the film casting machines produced in China are heated by heating tubes and heating plates. The structure is composed of a sealed cavity, and heating tubes or heating rods are arranged up and down in the cavity. It is a way to heat the casting film on the transmission steel belt passing through the cavity. Because the traditional equipment is dried by the heat radiation method of the resistance heating tube, and the resistance heating tube has unstable heating, and the heat transmission mode of heat radiation is prone to unstable heating and uneven heating space. The drum of the mechanism only uses two supporting seats. Due to its insufficient bearing capacity and anti-torque force, the operation is unstable. Its structure is generally limited to cast film within 300mm wi...
