Mixed heating system used for pre-shrinking machine

Abstract

The invention discloses a mixed heating system used for a pre-shrinking machine. The mixing heating system comprises a heating plate and a steam heating pipe, wherein the steam heating pipe is arranged in the heating plate; the heating plate comprises an electric heating pipe; the steam heating pipe and the electric heating pipe are of U-shaped structures; the electric heating pipe is arranged on the inner side of the steam heating pipe; an electric heating wire is arranged in the electric heating pipe; a temperature sensor is arranged on the heating plate. The mixed heating system also comprises a temperature control device, and the temperature control device is connected with the temperature sensor on the heating plate. The mixed heating system used for the pre-shrinking machine, which is applicable to a plurality of fabrics and can quicken drying is made by adopting the technical scheme; on the basis of reserving the original steam heating pipe, the electric heating pipe is added, the applicable range of multiple fabrics can be met by a drying process through the temperature adjustability of the electric heating pipe, and the aims of improving fabric shrinking quality and fabric shrinking efficiency are finally achieved.

Description

technical field [0001] The invention relates to the field of fabric treatment, in particular to a hybrid heating system for a pre-shrinker. Background technique [0002] The purpose of the pre-shrinking of the pre-shrinking machine is to obtain a stable fabric size. Generally, the shrinkage effect is required to reach a shrinkage rate of less than 3% in the warp and weft directions. Reach certain weight and stiffness requirements. [0003] The main process of the shrinking machine includes steam spraying, drying, dehumidification and cooling. In today's industry, steam heating is generally used to achieve the purpose of drying. The system structure used in this method is as follows: figure 1 As shown, the main equipment is the steam heating tube 11, but since the steam is under a certain pressure, the temperature cannot be set, so it faces problems such as being unable to adapt to the temperature requirements of various fabrics, and the drying speed is slow.
