Air transfer ducts 60 formed with 62b and 62c; One end is communicatively coupled to the upper and middle outlet ports 62a and 62b, spaced up and down by a predetermined interval so that the fiber fabric T can pass therethrough, and face each other so that air is injected to the top and bottom surfaces of the fiber fabric T, respectively. A pair of air injection ducts 50 each having an air injection hole 51 formed at a viewing surface thereof, and the flame f of the burner 70 installed in the air transfer duct 60 is provided at the driving motor 40. The driving force is applied to the hot air supply system of the tenter configured to blow air to the air injection duct 60 through the air transfer duct 60 by mixing with the air by the axial flow fan 42 is rotated.

Reference numeral 20 denotes a rectangular parallelepiped support frame formed by interconnecting several vertical and horizontal supports 21 and 22, and 30 denotes a lower portion of a pair of vertical wall plates 31 and 31a facing each other in left and right directions. A fiber fabric inlet 31 'and a fiber fabric outlet 31a' are formed and are sealed members fixed to each side of the support frame 20.

Reference numerals 32, 33, 31b, and 31c are wall plates constituting the sealing member, and 63 is a branching member for branching the flow of hot air to flow to the pair of air injection ducts 50.

As shown in FIG. 3, the doors 80 and 80a are installed in the upper and middle outlet ports 62a and 62b so as to be rotatable through the hinge shafts 81 and 81a, respectively, and the air transfer duct 60 is provided. The air cylinder 90 is installed on the outer side of the outer wall, preferably on the outer side surface of the vertical wall plate 31, and the first rods 91 and 91a of the predetermined lengths on the hinge shafts 81 and 81a of the doors 80 and 80a. Is fixedly installed, and second rods 92 and 92a of a predetermined length are rotatably installed at the end portions of the first rods 91 and 91a, and end portions of the second rods 92 and 92a are triangular pieces 93, 93 ') is rotatably installed at any one of the vertices 93a, 93b, and 93c of one of the three vertices 93a, 93b, and 93c, and one of the remaining vertices 93b and 93c of the triangular pieces 93, 93'. 93c is rotatably installed on the actuating rod 90a, and the other vertex 93b of the triangular pieces 93, 93 'is located outside the air transfer duct 60, preferably the sealing member 30. Rotating to the vertical wall plate 31 constituting the It is.

Referring to Figures 3 and 4 the operation of the door opening and closing device according to the present invention configured as described above are as follows.

First, when the fiber fabric T is stopped between the air injection ducts 50 and the transfer is stopped due to external conditions, the drive motor 40 and the burner 70 are operated by a control system (not shown). Is stopped.

At this time, even if the operation of the drive motor 40 is stopped, the motor shaft is rotated for a predetermined time due to the residual current, and the hot air existing in the air transfer duct 60 is blown to the air injection duct 50, and the fiber fabric (T) is reached.

As described above, when hot wind is supplied to the fiber fabric (T) when the transfer of the fiber fabric (T) is stopped, the hot air to the air injection duct (50) should be blocked because it adversely affects the fiber fabric (T). do.

For the same reason as above, the control system operates the air cylinder 90.

When the air cylinder 90 is actuated, the actuating rod 90a is advanced upward. Then, when the actuating rod 90a is advanced upward, the triangular pieces 93, 93a are in the state as shown in FIG. ) Rotates clockwise around the vertex 93b.

Thereafter, when the triangular pieces 93 and 93a are rotated in the clockwise direction, the second rods 92 and 92a are rotated in the clockwise direction by receiving the rotational force of the triangular pieces 93 and 93a.

Thereafter, when the second rods 92 and 92a are rotated in the clockwise direction, the first rods 91 and 91a are rotated in the clockwise direction by receiving the rotational force of the second rod.

As described above, when the first rods 91 and 91a are rotated in the clockwise direction, the doors 80 and 80a are rotated in the clockwise direction about the hinge shafts 81 and 81a, and eventually the upper and middle outlet ports 62a. And 62b) in the open state.

Here, the door (80a) of the door (80, 80a) is opened in a state in which the lower outlet 62c is closed to close the middle outlet (62b).

As described above, by operating the air cylinder 90, the hot air remaining in the air transfer duct 60 in accordance with the drive stop of the drive motor 40 is driven by the rotational force of the axial flow fan 42, the air injection duct 50 It is not discharged to all will be discharged through the lower outlet (62c).

Therefore, the hot air is no longer supplied to the fiber fabric which is stopped between the air injection ducts, thereby protecting the fiber fabric.

Here, in the above description, when the operating rod of the air cylinder is operated in the upward direction, the upper and the middle discharge port is configured to be closed by the door, but the operating rod of the air cylinder is configured to be operated in the downward direction so that the upper and the middle discharge port It may be possible to close it.

As described above, according to the present invention, the drive means for operating the door of the hot air supply system of the tenter and the configuration of the door to be opened and closed by the drive means to be more precise, so that the door opening and closing operation is made accurately, When the transfer of the fiber fabric passing between the injection ducts is stopped, the outlet of the air delivery duct is blocked so that hot air is not excessively supplied to the fiber fabric.
