Sectional type heating mechanism used in heating roller

Abstract

The invention provides a sectional type heating mechanism used in a heating roller. The sectional type heating mechanism comprises a plurality of heating assemblies arranged in sections, each heatingassembly comprises a heating base, a heating base mounting hole is arranged in the heating base, a plug capable of popping up is arranged in the heating base, the plug can extend out of a side wall ofthe heating base mounting hole, insert plates are connected to the outer wall of the heating base, one ends of the insert plates are connected to the heating base, the other ends of the insert platesare equipped with heatproof sealing strips, a heating plate is arranged between two adjacent insert plates, an electric heating pipe is arranged on the heating plate and is connected to the plug through a wire; and the electric heating pipes on the heating plates of all the heating assemblies are independently controlled, and each heating assembly is provided with a temperature sensor. The heating assemblies of all sections are independently controlled according to the actual temperature, and a basically consistent temperature can be guaranteed to all sections of the heating roller.

Description

technical field [0001] The invention relates to the field of composite machines, in particular to a segmented heating mechanism used in heating rollers. Background technique [0002] Composite fabric is a new type of material made by bonding one or more layers of textile materials, non-woven materials and other functional materials. It is suitable for sofas, clothing and other textiles, and is one of the indispensable fabrics for people's home life. . Laminating machine is mainly used for laminating production process of two or more layers of various kinds of cloth, leather, film, paper, sheet and so on. Most of the existing composite machines are composite machines for soft materials such as fabrics and leather. These composite machines are carried out through processes such as feeding, gluing, and pressing. For pressing, sometimes hot pressing is required for some special glues, that is, it needs to be carried out by heating the pressure roller. The existing pressure rol...

AI Technical Summary

Problems solved by technology

Most of the existing composite machines are composite machines for soft materials such as fabrics and leather. These composite machines are carried out through processes such as feeding, gluing, and pressing. In the pressing stage, it is carried out by two upper and lower pressure rollers. For pressing, sometimes hot pressing is required for some special glues, that is, it needs to be carried out by heating the pressure roller. The existing pressure roller mainly heats the pressure roller through electric heating wire or electric heating tube, but such a method exists The problem is as follows, because the heating roller is placed at both ends to dissipate heat quickly, and the heat dissipation in the middle is slow, which will cause uneven heating of the hot pressing roller and affect the quality of hot pressing
