The support bracket 440 is configured to support a lower portion of the connection pipe 430.
Thereby, the support frame 440 can adjust the height according to the coupling height of the first and second adjustment nuts 454 and 455, and adjust the height of the connection pipe 430 and the lower injection pipe 320 inserted into the connection pipe 430 according to the height of the support bracket 440.
The connection duct 430 has a structure in which a communication hole 435 communicating with the inside of the lower injection duct 320 to supply hot air supplied through the long hole 410 thereto is formed, and a flange plate 432 is formed at one side portion to seal the remaining portion except the portion communicating with the long hole 410 when adjusting the height.
Further, a bent portion 434 that enters the inside of the lower injection duct 320 is formed to protrude at the other side of the connection duct 430, and the bent portions 434 are spaced apart from each other in the lateral direction in a manner corresponding to the interval of the lower injection duct 320.
As shown in fig. 2, a plurality of long holes 410 are formed at regular intervals in the lateral direction at the front side of the lower branch pipe 220, and a plurality of fixing holes 425 are formed at regular intervals in the lateral direction on the support plate 420 so as to correspond to the respective long holes 410.

The flange plate 432 of the connection duct 430 can prevent hot air loss by blocking an open portion of the long hole 410 when the connection duct 430 is lifted and lowered.
Referring to fig. 1, a suction guide duct 500 for supplying hot wind heated by the heater 50 (burner) to the inside of the supply duct 100 is further provided in the suction port 105 of the supply duct 100.
An inner diameter height H1 of the suction guide duct 500 at one side portion of the heater 50 has a larger inner diameter (H1> H2) than an inner diameter height H2 of the supply duct 100 at the other side portion, and an extension portion 510 for allowing the other side portion of the suction guide duct 500 to enter and be fitted into the suction port 105 of the supply duct 100 is formed.
By forming the extension 510 such that the other side of the suction guide duct 500 is inserted into the suction port 105 coupled to the supply duct 100 and the other side is coupled to the hot air duct 60, it is possible to prevent interference from occurring when the lower ejection duct 320 performs a descending operation.
The present invention configured as described above requires the height of the lower spray pipe 320 to be adjusted according to the type of the cloth supplied to the inside of the tenter and transferred, so as to prevent the lower portion of the cloth from contacting the lower nozzle 20 cap when the cloth is sagged, and the operation of adjusting the height of the lower spray pipe 320 by the height adjusting means 400 according to the degree of sagging of the cloth.
As the operation of adjusting the height adjusting member 400, in the case of performing the lifting operation among the lifting operations of the support bracket 440, after the first adjusting nut 454 is rotated in one direction to lift the first adjusting nut 454 and thereby increase the interval with the second adjusting nut 455, the support bracket 440 is lifted upward to adjust the height thereof, and then the second adjusting nut 455 is rotated in one direction to closely attach to the lower side of the lifted support bracket 440 and thereby adjust the interval with the first adjusting nut 454 to the original interval, so that the first and second adjusting nuts 454 and 455 are positioned on the upper and lower sides of the lifted support bracket 440 and fix the support bracket 440 to the lifted position.
On the contrary, when the support bracket 440 is lowered, the second adjustment nut 455 is rotated in the other direction to lower the support bracket 440 to a desired height and then to lower the support bracket 440 to the side of the lowered second adjustment nut 455, and then the first adjustment nut 454 is rotated in the other direction to lower the support bracket 454 to be closely attached to the upper side of the lowered support bracket 440, so that the first and second adjustment nuts 454 and 455 are positioned at the upper and lower sides of the lowered support bracket 440 and fix the support bracket 440 to a lowered position.
The height adjusting members 400 are respectively disposed at both left and right side ends of the support bracket 440, and can adjust the height of the connection pipe 430 and thus the height of the lower injection pipe 320 inserted into the connection pipe 430 by adjusting the height of the support bracket 440 supporting the lower portion of the connection pipe 430.
Accordingly, when the height of the connection duct 430 is adjusted, one side of the connection duct 430 is moved up and down between the support plate 420 and the front side surface of the lower branch duct 220, and the open portion of the long hole 410, which is changed according to the change of the communication position with the long hole 410, is sealed by the flange plate 432 formed at one side of the connection duct 430, thereby preventing the loss of hot air.
In addition, by rotating the blower fan 110 provided inside the supply duct 100 by the driving motor 150, the hot air heated by the heater 50 can be supplied to the upper branch duct 210 and the lower branch duct 220.
In the upper branch duct 210, the hot wind is transferred to the inside of the upper injection duct 310 along a path which collides with the first curved surface 215 after entering through the first upper duct 212 in the vertical direction and is supplied to the inside of the second upper duct 214 in the horizontal direction.
At this time, the second upper duct 214 of the upper branch duct 210 has a wider sectional length than that of the first upper duct 212, whereby the offset and disturbance phenomena of the hot wind can be minimized in the process of being supplied to the inside of the upper injection duct 310 through the upper branch duct 210.
Further, the lower branch duct 220 may perform a function of transferring the hot wind to the inside of the lower spray duct 320 along a path that collides with the second curved surface 225 and is supplied to the inside of the second lower duct 224 in the horizontal direction after the hot wind enters along the first lower duct 222 formed in the oblique line direction of the inclination angle.
At this time, since the second lower duct 224 of the lower branch duct 220 has a sectional height greater than that of the first lower duct 222, it is possible to minimize a disturbance phenomenon of the hot wind due to a bottleneck structure in the process in which the hot wind is supplied to the inside of the lower spray duct 320 through the lower branch duct 220.
Since the upper nozzles 10 are disposed at the lower side of the upper spray duct 310 and the lower nozzles 20 are disposed at the upper side of the lower spray duct 320, it is possible to judge the type of the cloth or the sagging degree of the cloth and set the height adjusting part 400 before transferring the cloth to the inside of the tenter, thereby disposing the lower nozzles 20 at a position close to the lower side of the cloth as much as possible while preventing the contact between the cloth and the lower nozzles 20 and thereby improving the drying efficiency of the cloth.
The present invention can prevent the cloth from being damaged and improve the drying efficiency of the cloth by adjusting the height of the lower nozzle 20 and the lower spray pipe 320 to prevent the lower side of the cloth from contacting the lower nozzle 20 in consideration of the type of the cloth and the degree of sagging during the transfer, and by approaching the lower nozzle 20 to the lower side of the cloth as much as possible while preventing the lower side of the cloth from contacting the cloth.
In the present invention, the vertical flange plate 432 is formed at one side of the connection duct 430, so that the one side of the connection duct 430 can be moved up and down between the support plate 420 and the front side surface of the lower branch duct 220 when adjusting the height of the connection duct 430, and the open portion of the long hole 410, which is changed according to the change of the communication position with the long hole 410, is sealed, thereby preventing the loss of hot air.
The present invention can move the support bracket 440 up and down according to the rotation direction of the first and second adjustment nuts 454 and 455 with respect to the elevation shaft 453 when adjusting the height of the support bracket 440, thereby conveniently performing the up and down elevating movement of the support bracket 440 by the screw coupling manner of the first and second adjustment nuts 454 and 455.
The suction guide duct 500 of the present invention has a height greater at one side portion of the heater 50 than at the other side portion of the supply duct 100, and has an extension portion 510 for inserting the other side portion of the suction guide duct 500 into the suction port 105 of the supply duct 100, thereby preventing the occurrence of interference when the lower nozzle 20 is lowered and preventing the increase in volume of the tenter even when the volume of the blowing fan 110 is increased.
As described above, the specific embodiments of the present invention have been described in the detailed description of the present invention, but the present invention can be variously modified within a range not departing from the scope thereof. Therefore, the scope of the present invention should not be limited to the embodiments described in the above-mentioned contents, but should be defined by the appended claims and the scope equivalent to the claims.
