1 and 2, the present invention has a rectangular parallelepiped support frame 20 formed by interconnecting several vertical and horizontal supports 21 and 22; A fiber fabric inlet 31 'and a fiber fabric outlet 31a' are respectively formed at a lower side of a pair of one side wall plate 31 facing each other in the left and right directions, and are hermetically fixed to each side of the support frame 20. Member 30; Air injection holes (not shown) are spaced apart from each other by a predetermined interval so that the fiber fabric (T) introduced into the fiber fabric inlet 31 ′ is faced to face each other so that air is injected onto the top and bottom surfaces of the fiber fabric. A pair of air injection nozzles 50 each of which is formed and fixedly installed up and down inside the support frame 20; One side is formed with an inlet 61a through which air is sucked, and the other side is formed with upper, middle, and lower outlets 62a, 62b, and 62c so that the air is branched and discharged through three paths, and the upper and middle outlets 62a. (62b) is connected to the air injection nozzle 50, respectively, and the air transfer duct 60 is fixedly installed on the upper side of the support frame 20; A pair of bypass dampers 80 and 80a installed in the upper and middle outlet ports 62a and 62b so as to be rotatable, respectively, so as to alternately open and close the lower outlet 62c at the middle outlet 62b; And a driving means (90) for driving the bypass damper and warmed by the flame generated from the burner assembly furnace (200) by the turbo fan (101, 101a) which is rotated by receiving the driving force of the driving motor (100, 100a). It is applied to a hot air supply system of a tenter configured to sequentially supply heat to the air transfer duct 60 and the air injection nozzle 50.

The driving means is provided with bypass dampers 80 and 80a rotatably through the hinges 81 and 81a in the upper and middle discharge ports 62a and 62b, respectively. Preferably, the air cylinder 90 is installed on the outer surface of the vertical wall plate 31 constituting the sealing member 30.

Here, the driving means may be installed on the inside of the air transfer duct 60, the reason is that the degree of foreign matter content varies greatly depending on the type of fiber fabric, the operation of the driving means due to the adhesion of the foreign matter This is to prevent incapacity.

And, it is to be able to respond elastically according to the size of the air transfer duct.

That is, when the size of the air transfer duct is small, the driving means is installed on the outside, and in the opposite case, the drive means is installed on the inside of the air transfer duct to maintain or reduce the appearance size of the entire tenter uniformly. You can do it.

The driving means is fixed to the hinge shafts 81 and 81a of the bypass dampers 80 and 80a, and the first rods 91 and 91a having a predetermined length are fixed to the end portions of the first rods 91 and 91a. The second rods 92 and 92a of length are rotatably installed, and the ends of the second rods 92 and 92a are any one of the three vertices 93a, 93b and 93c of the triangular pieces 93 and 93 '. It is rotatably installed at the vertex 93a, and any one vertex 93c of the other two vertices 93b and 93c of the triangular pieces 93 and 93 'is rotatable to the operating rod 90a of the air cylinder 90. And the other vertex 93b of the triangular pieces 93 and 93 'is rotatable to the outside of the air transfer duct 60, preferably to the vertical wall plate 31 constituting the sealing member 30. Installed and configured.

Here, reference numeral 63 is a hot air branch member.

As shown in FIGS. 2 and 3, the turbo fans 101 and 101a are horizontally spaced apart from each other by a predetermined space in the inlet portion 61a side of the air transfer duct 60, and the turbo fans 101 and 101a are positioned. a) is connected to the motor shafts 102 and 102a of the pair of drive motors 100 and 100a fixedly installed on the upper plate 32 of the sealing member 30 and rotated independently of each other, and the burner assembly 200 is generated from the flame. The hot air is applied to the hot air supply system of the tenter machine which is fixedly installed outside the right side wall plate 31c of the sealing member 30 so that the hot air can be ejected from directly below the turbo fans 101 and 101a.

As shown in FIG. 4, a 'T' shaped hot air discharge pipe 210 is provided directly below the turbo fans 101 and 101 a, and the hot air discharge pipes 210a and 210b of the burner assembly 200 are provided. A connection pipe 210a of a predetermined length that is flangeably connected to an end of a flame jet pipe (not shown), and a branch pipe 210b that is centrally connected to an end of the connection pipe 210a. Is done.

As described above, by installing the hot air discharge pipe 201 of the burner assembly 200 directly below the turbo fans 101 and 101a, as shown in FIG. 3, hot air is bypassed to the lower discharge port 62c to burner. There is no need to stop the operation of the 200 and the turbo fan (101, 101a), there is an energy saving effect without the loss of hot air energy as a whole does not always fall below a certain value inside the chamber.

On the other hand, in the case of a system in which hot air is not bypassed, when the machine is stopped during the transfer of the fiber fabric, the power supply to the driving motor is immediately stopped and the transfer of the fiber fabric is stopped.

At this time, as soon as the turbo fan is not rotated due to the stop of the driving motor, hot air is not sprayed by the air injection nozzle.

This is because the turbo fan keeps rotating for a predetermined time due to the residual current supplied to the drive motor, and then stops, so hot air is continuously discharged to the injection hole of the air jet nozzle until the turbo fan is completely stopped. This resulted in a phenomenon that a stop mark or streaked mark appeared on the fiber fabric.

The present invention, as described above, since the hot air can be supplied for a predetermined time even when the device and the driving motor is stopped, it is possible to fundamentally prevent the degradation of the fiber fabric.

A plurality of hot air discharge holes 211 having a predetermined diameter and an arbitrary arrangement are formed on a lower surface of the branch pipe 210b constituting the hot air discharge pipe 210.

Here, the hot air discharge hole 211 is preferably such that the diameter gradually increases toward the end side of the branch pipe (210b).

The reason for gradually increasing the diameter of the hot air outlet hole 211 as described above is that when the heat of the flame generated in the flame ejection pipe 220 flows through the connection pipe 210a and the branch pipe 210b, To be discharged.

On the other hand, in a preferred embodiment of the present invention, both ends of the branch pipe (210b) constituting the hot air discharge pipe 210, the extension pipe of a predetermined length is installed so as to communicate, a plurality of hot air discharge holes (211) on the lower surface of the extension pipe. Is formed.

Here, the hot air discharge hole 211 formed in the branch pipe 210b of the hot air discharge pipe 210 is formed to increase in diameter toward the end side.

Reference numeral 200a in the burner assembly 200 is a burner fan that supplies air from the outside so that fuel such as gas is mixed with air and ignited.

Although not shown in another embodiment of the present invention, instead of the burner assembly described above, a circulation pipe bent in a predetermined shape is installed in a space corresponding to the turbo fan directly below, and the steam or heat medium is supplied into the circulation pipe to circulate the same. It is, of course, possible to install a radiator to allow the pipes to dissipate hot heat.

Referring to the operation of the present invention configured as described above are as follows.

The fiber fabric T injected through the fiber fabric inlet 31 ′ of the front wall plate 31 constituting the sealing member 30 is moved between the air injection nozzles 50, in which the burner assembly 200 is operated. When a flame is generated, the driving motors 100 and 100a are sequentially driven by applying current.

As the drive motors 100 and 100a are driven, the motor shafts 102 and 102a rotate the turbo fans 101 and 101a. As shown in FIG. 5, the turbo fans 101 and 101a are opposite directions. The hot air of the flame generated by the burner assembly 200 in the straight direction is ejected through the connecting pipe 210a and then flows into the branch pipe 210b.

As described above, the hot air of the flame introduced into the branch pipe 210b is ejected downward through the hot air discharge hole 211 formed in the branch pipe 210b, and is mixed with the air flowing in from the bottom. Inhaled).

Thereafter, the hot air sucked into the turbo fans 101 and 101a is mixed once again by a pair of rotating turbo fans.

The air is then transferred into the air transfer duct 60 at the same pressure by a pair of fans rotating opposite to each other.

Thereafter, the hot air transferred into the air transfer duct 60 is mixed again in the interior thereof.

As a result, the hot air is evenly mixed to flow evenly spread inside the air transfer duct (60).

That is, the temperature deviation of the heat from the air transfer duct 60 is not generated.

The heat flowing along the air transfer duct 60 is thus sufficiently reached to the air injection nozzle 50 by the rotation of the two turbofans (101, 101a).

That is, the heat of the burner assembly 200 is converted into hot air by the blowing of the turbo fans 101 and 101a, so that temperature deviation does not occur even at each point of the air injection nozzle 50, thereby further improving the quality of the fiber fabric. You can do it.

As described above, according to the present invention, the structure in which the hot air generated in the burner assembly, that is, the ignition of the flame is discharged more specifically, to be forced to be sucked by the turbo fan which is effectively rotating.
