Abstract

The invention provides a device for melting a thermo-sensitive film master batch by adopting a form of a vacuum tank. The device for melting the thermo-sensitive film master batch comprises a fixed frame, a nitrogen inlet pipe, a circulation chamber, a three-level pressurizing chamber and a vacuum chamber. The fixed frame is installed on a wall. A tank body is fixed to the middle of the fixed frame. The three-level pressurizing chamber is controlled by a hydraulic rod above the fixed frame. The vacuum chamber is arranged in the circulation chamber. The gas inlet end of the nitrogen inlet pipe is arranged on the three-level pressurizing chamber. The gas outlet end of the nitrogen inlet pipe is directly connected with a gas inlet of the vacuum chamber. The tail end of the circulation chamber is further provided with a wind suction implement. According to the device for melting the thermo-sensitive film master batch, the form of the vacuum tank is adopted for melting the thermo-sensitive film master batch, so that the thermo-sensitive film master batch does not contain impurities of air any more, and accordingly the quality and the sensitivity coefficient of a finished film is effectively improved.

Description

technical field [0001] The invention relates to temperature-sensitive film manufacturing equipment, in particular to a device for melting a temperature-sensitive film masterbatch in the form of a vacuum tank. Background technique [0002] At present, the temperature-sensitive film is a sensitive film material. If there are air bubbles or other impurities in the finished film, the quality of the temperature-sensitive film will be greatly affected, thereby affecting its sales. In the previous manufacturing process of temperature-sensitive film, the masterbatch was melted by ordinary heating method, and then blown into film. And because there are a lot of undefined impurities in the air, there are a lot of impurities and air bubbles in the finished film. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a device for melting the temperature-sensitive film masterbatch in the form of a vacuum tank, so as to solve the ab...
