Description

Damper Device for Hot Air Distribution of Tenter Machine The present invention relates to a damper device for a tenter machine, and more specifically, to a damper device for a tenter machine in which a damper is rotatably positioned inside the tenter machine to distribute hot air to the upper and lower injection ducts, respectively, so that the opening angle of the damper, which varies due to the rotational movement of the damper, can be easily adjusted from the outside of the chamber, and the structure is improved so that the opening angle of the damper can be visually confirmed using an interlocking block that moves to the left and right when the adjustment shaft rotates and an arrow-shaped indicator member. The present invention relates to a damper device for a tenter machine, the structure of which is improved to enable precise control of the amount of hot air distributed to the upper and lower injection ducts by using a screw fastening method of the control shaft, prevent the formation of vortices within the upper and lower guide ducts, easily adjust the distribution ratio of hot air sprayed to the upper and lower sides of the fabric by considering conditions such as the type of fabric and shrinkage rate, and enable fine adjustment and precise control of the rotation angle of the damper. Generally, processing steps for fabric materials such as woven or knitted fabrics include a heat setting process performed as a pre-dyeing treatment, a drying process performed as a post-dyeing treatment, and a shrinkage process by heat treatment, and tenter machines are mainly used as devices to perform these processes. A conventional tenter machine comprises: a chamber in which a fabric material passes horizontally through an upper space and is equipped with a fabric material inlet and a fabric material outlet at the upstream and downstream ends, respectively, in the direction of transport of the fabric material; a hot air generating duct disposed in the lower space of the chamber; a heater coupled to one side of the hot air generating duct; a hot air supply duct connected to the other side of the hot air generating duct, extending upward, and having a plurality of hot air outlets that open toward one side of the hot air generating duct at the upper side; a channel-type nozzle body with an inlet end mounted at the hot air outlet of the hot air supply duct and the other end closed, and upper and lower hot air injection nozzles coupled to the surface of the nozzle body facing the fabric material and having a plurality of nozzle holes formed therein; It comprises a blower installed at the bottom of the hot air supply duct, which sucks in air from the chamber through the heater and the hot air generating duct, blows it into the interior of the hot air injection nozzle through the hot air supply duct, and causes the hot air to be sprayed onto the upper and lower surfaces of the fabric through the nozzle holes of the hot air injection nozzle. The total length of the chamber is determined in accordance with the transfer speed and processing conditions for the processing of the fabric. The chamber is constructed by connecting a plurality of unit chambers, each having a length that divides the total length equally. The fabric inlet and fabric outlet are provided in the upstream and downstream unit chambers, respectively, which are installed at the upstream and downstream ends of the unit chambers. In performing the heat setting process, drying process, and shrinking process using a conventional tenter machine, when the blower and heater are operated while conveying the fabric, the air inside the chamber is sucked in by the blower through the heater into the hot air generating duct, and as the sucked air comes into contact with the heater, it is heated by heat exchange to generate hot air of about 180°C to 220°C, and the generated hot air is supplied by the blower into the interior of the hot air injection nozzle through the hot air supply duct. The hot air supplied into the interior of the hot air injection nozzle is sprayed onto the upper and lower surfaces of the fabric through multiple nozzle holes formed in the nozzle plate of the hot air injection nozzle to perform a heat setting process, a drying process, or a shrinkage process. As for prior art related to the supply of hot air for a conventional tenter machine, as disclosed in Korean Registered Patent Publication No. 10-320004 "Hot Air Supply System for a Tenter Machine" (Registration Date: Dec. 24, 2001), the hot air supply system for a tenter machine is configured to sequentially supply heat heated by a flame generated from a burner assembly to the air transfer duct and the air injection nozzle by means of a turbo fan that rotates by receiving the driving force of a driving motor, wherein a pair of turbo fans are positioned horizontally spaced apart at a predetermined distance inside the inlet side of the air transfer duct, and the turbo fans are connected to the mot
