[0001] HOT WIND SUPPLY APPARATUS FOR TENTER MACHINE [0002]

The present invention relates to a hot air supplying apparatus for a tenter machine, and more particularly, to a hot air supplying apparatus for a tenter machine, which supplies hot air through upper and lower supply ducts, So as to uniformly distribute the hot air. In addition, in order to prevent the thermal damage of the fiber fabric in the case where the transfer of the fabric of the tenter device is stopped, The present invention relates to a hot air supply device for a tenter frame which can be bypassed.

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.

Prior art related to the conventional tenter machine is disclosed in Korean Patent Publication No. 10-0613898 entitled " Hot Air Supply and Distribution Structure of Tenter Machine "(Registered Date: 2006.08.10) A circulation fan for forcedly circulating and supplying hot air to the air guide duct side, and a circulation fan for circulating and supplying hot air to the air guide duct side, And a heating member for reheating air to be guided through the duct member, wherein the air guide duct is forcedly conveyed by a circulating fan, And the upper branch duct and the lower branch duct for guiding the generated hot air to the upper and lower hot air blowing ducts, respectively, and each of the branch ducts And the guide passages having the same shape and length are formed by the intermediate partition walls. In addition, a throttle plate for adjusting the distribution of the hot air supply amount branched at the branch point of the upper branch duct and the lower branch duct is provided.

However, in the above-described prior art, the amount of hot air supplied to the upper and lower branch ducts is regulated by one fan driving motor by using a throttle plate. However, each of the branch ducts has the same shape and length The guide flow path is formed to have the same width for each part. Therefore, the shorter the length of the guide flow path, the greater the deviation of the hot air supply amount. If the length of the guide flow path is increased to solve this problem, There is a problem that the unit cost of the product is increased due to the increase in volume. In addition, the throttle plate can not precisely control the amount of hot air supplied to the upper and lower portions, and when one of the upper and lower branch ducts is blocked by the throttle plate, the amount of hot air supplied to the other increases. In addition, when hot air heated by a heater such as a burner is not uniformly distributed in the branch duct and is not uniformly supplied, the temperature of the hot air supplied to each part of the fiber cloth during transportation is varied, There is a problem. In addition, when the transfer of the fiber fabric is stopped due to the temporary stop state of the tenter device, there is a possibility that the fiber fabric is damaged due to the supply of hot air to the guide flow path, so that the operation of the heater such as the burner can be stopped, In this case, when the temperature in the chamber is lowered and the heater and the fan are restarted, it takes a long time to preheat the temperature in the chamber and energy is wasted. In addition, there is a drawback that the temperature in the chamber is set at a set temperature There is a problem in that defects are generated in the fabric produced before reaching.
