Description

Heating device for continuous weight reduction of textile products The present invention relates to a heating device for a continuous fabric reduction machine, and more specifically, to a heating device for a continuous fabric reduction machine with an improved structure for a steam heating device that raises the temperature inside the chamber of a continuous fabric reduction machine, wherein steam injection pipes are installed on the left and right sides of a single heating device to transfer the heated steam heat along the direction of travel of the fabric inside the chamber to the left and right sides of the reduction machine chamber, thereby raising the temperature inside the reduction machine chamber to a uniform temperature, and the temperature inside the reduction machine chamber can be heated to a high temperature of 120°C or higher using a burner of the heating device, so as to improve the reduction efficiency of the fabric and improve productivity by increasing the speed of the conveying roller. Generally, as a pre-dyeing treatment process for woven fabrics, a reduction operation is performed using a reduction machine to improve the feel or marketability of the fabric. Such reduction machines are broadly classified into tank reduction methods, liquid flow reduction methods, and continuous reduction methods. Among them, this is not a significant issue in the case of tank or liquid flow types, but in the case of continuous types, especially net types, the weight reduction reaction occurs simultaneously while the fabric is being fed inside the reaction tank, and furthermore, uniform quality can only be maintained if the tension is kept constant within an appropriate range of the fabric during the weight reduction operation. The aforementioned reduction process of the fabric is performed to improve the soft texture of the fabric through surface treatment during the process of heating the fabric with high heat. As for prior art related to existing fiber reduction machines, as disclosed in Korean Utility Model Publication No. 20-1998-0016279 "Tension control device for fiber fabric for reduction machine" (Date of publication: June 25, 1998), it relates to a device for precisely controlling the required tension by individually controlling the driving speed of the feed rollers at each stage for the amount of fiber fabric being fed in the reduction machine. As another prior art related to existing fiber reduction devices, as disclosed in Korean Registered Patent Publication No. 10-1448011 "Continuous weight reduction processing device for polyester fiber products" (Registration date: September 30, 2014), a continuous weight reduction processing device for polyester fiber products composed of an immersion section, a heat treatment section, a washing section, and a loading section is configured such that the steaming chambers constituting the heat treatment section are arranged side by side, and a preheating heater is installed at the entrance of the steaming chamber to rapidly heat the fiber products flowing into the first steaming chamber to a desired temperature, and the first steaming chamber and the second steaming chamber are connected by a connecting pipe so that the fibers flow directly from inside the first steaming chamber into the second steaming chamber, and a water seal device is provided at the outlet of the second steaming chamber so that the inside of the second steaming chamber is completely sealed off from the outside through the water seal device. However, conventional prior art related to existing fabric reduction machines uses steam and steam heaters to introduce heat into the reduction machine chamber. However, due to factory site conditions, it is difficult to raise the temperature to approximately 110°C or higher with a steam heater. Furthermore, if the fabric is to be heated and dried at a relatively low temperature of 110°C or lower, the speed of the conveyor roller must be reduced to maintain a long heating time for the fabric to reduce the fabric, which raises concerns about reduced productivity. Additionally, depending on the arrangement structure of the heating tubes, there is a concern that temperature differences may occur between the left and right sides of the heating temperature inside the reduction machine chamber. FIG. 1 is a schematic diagram showing the configuration of the continuous weight reduction machine of the present invention. FIG. 2 is a front view showing a heating device of a continuous weight reduction machine for textile fabrics according to the present invention. Fig. 3 is a side view of Fig. 2. FIG. 4 is a plan view of FIG. 3, showing a usage state diagram in which the heat of the burner moves inside the heating housing through the gas pipe and the exhaust pipe. In describing the present invention, if it is determined that a detailed description of related prior art or configurations could unnecessarily obscure the essence of the invention, such detailed
