Splayed double-branch channel type heating drying gun and using method thereof

Abstract

The invention relates to the field of reinforcing polymer compounds by using loose or adhered fibrous materials, in particular to a splayed double-branch channel type heating drying gun and a using method thereof. The splayed double-branch channel type heating drying gun comprises an air blower (1), and is characterized by further comprising a ceramic core resistance wire gun body (2) and an air duct (3), wherein the air duct (3) is characterized in that a lower air duct body (31) and an upper air duct body (32) are connected with an air inlet to form an angle shape with an open end. The usingmethod of the splayed double-branch channel type heating drying gun is characterized by being implemented sequentially according to the following steps of firstly, blasting; secondly, heating; thirdly, winding; and fourthly, hot melting. The heating drying gun and the using method have the advantages that the structure is simple, the use is convenient, the heating efficiency is high, and the product quality is good.

Description

technical field [0001] The invention relates to the field of reinforcing polymer compounds with loose or adhered fibrous materials, in particular to a figure-eight double-channel heating drying gun and its application method. Background technique [0002] The continuous glass fiber prepreg tape hot melt winding machine is used to produce "continuous glass fiber reinforced thermoplastic composite pipe". The usual methods of heating the prepreg tape include laser heating, infrared heating and hot air heating, but the more general and common methods are Hot air heating method. [0003] In the production process of hot air heating method, the effect of hot air is to simultaneously melt the continuous glass fiber prepreg tape and the plastic on the surface of the wrapped plastic pipe with sufficient heat, and to achieve rapid melting of the tape under the tension of the tension machine in the winding machine For the purpose of achieving the overall fusion of the strip and the pi...

Problems solved by technology

[0004] However, the heat guns in the existing market are all in the shape of a single port. The heat gun in the shape of a single port can only meet the surface heating of a single product, that is, to heat the continuous glass fiber prepreg tape of the hot melt winding machine or the surface of the plastic pipe fused by the prepreg tape. This single-port heat gun cannot meet the production process requirements of melting the continuous glass fiber prepreg tape and the plastic on the surface of the wrapped plastic pipe at the same time
