Constant temperature device for plasticizing air duct cloth

Abstract

The invention relates to a constant temperature device for plasticization of an air tubing cloth. The constant temperature device comprises a hollow barrel body, wherein annular sealing discs are arranged at two ends of the hollow barrel body, the annular sealing discs and the side wall of the barrel body can form a channel through which the air tubing cloth can penetrate, a circulating device is arranged on the barrel body and comprises at least two air ducts arranged in the side wall of the barrel body, an air inlet and an air outlet of each air duct are communicated with the channel, each air inlet is connected with a fan, a heating pipe located on the surface of the side wall of the barrel body is arranged above the air outlet, a perforated plate is adaptively arranged above the heating pipe, a plurality of exhaust holes are distributed in the perforated plate, and a temperature sensor is arranged in the barrel body. According to the constant temperature device for plasticization of the air tubing cloth, gas in the barrel body can circulate and be heated continuously through cooperation of the air ducts and the fan and the adaptation of the heating pipe and the perforated plate, temperature or heat in the barrel body can be distributed uniformly, and the plastifying quality of the air tubing cloth in the barrel body can be improved; and besides, the power of the heating pipe can be adjusted by the temperature sensor, and automatic constant temperature adjustment in the barrel can be realized.

Description

technical field [0001] The invention relates to a plasticizing device for the production of air tube cloth, in particular to a constant temperature device for plasticizing the air tube cloth. Background technique [0002] The existing fan cloth needs to be fully plasticized after coating, so that the base cloth can be fully combined with the paint to achieve the good technical characteristics required by the fan cloth, such as high strength, high wear resistance, folding resistance, and long life. The technical characteristics of the air duct cloth are generally plasticized in the plasticizing box, and the temperature in the plasticizing box must be ensured to be uniform. One end of the plasticizing box passes through the other end, and the air duct is uniformly heated in the plasticizing box; the existing plasticizing box is generally equipped with a heat pipe to heat the inside of the plasticizing box, but due to the air circulation in the plasticizing box If it is not sm...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a blower cloth plastic box for the problems of poor air circulation in the existing plasticizing box and uneven heat or temperature distribution in the prior art, which directly affect the plasticizing performance of the blower cloth. Chemical constant temperature device, the constant temperature device can fully circulate the air in the cylinder, make the heat or temperature distribution in the plasticizing cylinder more uniform, and improve the plasticizing quality of the air cylinder cloth
