TENTER MACHINE WITH DOUBLE DAMPER ADJUSTMENT DEVICE,

The present invention relates to a tenter unit having a double damper angle adjuster, and more particularly, to a tenter unit having a double damper angle adjuster, The present invention relates to a double damper angle adjuster.

Generally, a tenter machine is used as a device for performing a drying process and a heat treatment process, which are performed mainly as processing steps after dyeing during processing of a textile fabric.

Such a tenter machine has a system configuration for supplying hot air to a fiber fabric to be conveyed. A drive motor is provided at a lower portion of a substantially rectangular parallelepiped-shaped chamber. A circulating fan is fixedly installed on a motor shaft of the drive motor have.

Here, the circulation fan is a turbo fan configured to blow air at a right angle with respect to the direction in which air is sucked.

A duct member is fixedly installed between the burner (or the heater) and the circulating fan of the driving motor, and one end of the duct member is connected to the circulation fan And guiding the heat generated from the burner or the heater to flow toward the circulating fan in the direction of the arrow when the circulating fan is rotated by driving the driving motor.

The duct member to which the circulating fan is installed is branched and installed with an air guide duct communicating with the upper side thereof. The air generated by the burner or the heater is converted into hot air by the circulating fan and is introduced into the air guide duct. And the upper and lower branch ducts are spaced apart from each other so as to maintain a predetermined distance therebetween.

The upper and lower injection ducts have a structure in which the inside thereof is hermetically sealed with the outside, and nozzle holes (not shown) are formed on mutually facing opposite surfaces, so that hot air is sprayed.

However, in the case of such a conventional tenter, the hot air which is forcibly raised by the circulating fan flows into the air guide duct and is not uniformly distributed in the process of branching to the upper and lower branch ducts. There is a problem that the quality of the fiber fabric is deteriorated due to the occurrence of uneven heat and temperature distribution.

As a prior art document relating to a conventional tenter, Korean Patent Registration No. 10-0613898 (Prior Art 1) and Korean Patent Registration No. 10-1229347 (Prior Art 2) are known.

In the prior art document 2, the hot airflow control piece is provided on the upstream side of the nozzle hole formed in the nozzle plate, so that the hot airflow control piece is provided on the upper and lower surfaces of the fabric through the nozzle holes formed in the nozzle plate of the hot air jetting nozzle

The blowing angle (direction) of the blowing hot air is perpendicular to the upper and lower surfaces of the fabric, and the shrinking process by the heat setting process, the post-dyeing drying process, and the heat treatment is effectively performed.

However, in the prior art 1, it is impossible to precisely control the amount of hot air supplied to the upper and lower hot air blowing ducts, and when one side is blocked by the throttle plate among the upper and lower branch ducts, the amount of hot air supplied to the other side increases . In addition, there is a problem in that the supply amount of the hot air directed to the upper and lower hot air blast ducts in the two chambers can not be respectively adjusted by the two dampers which are tuned and operated by one angle adjuster.

Also, in the prior art 2, there is a problem in that the supply amount of the hot air directed to the upper and lower hot air blowing ducts in the two chambers can not be respectively adjusted by the two dampers operated by one angle adjuster respectively.
