TECHNICAL FIELD The present invention relates to a dry heat treatment machine having excellent efficiency and economy with a telescoping nozzle box as a cloth dryer or heat treatment machine, in particular a hot air nozzle device.

As a heat treatment machine for constructing a heat set or the like on a cloth dryer or cloth, the cloth extends in the direction of the cloth width above and below the cloth sent by a pin tenter, and is also opposed to the cloth (the surface facing the cloth). The nozzle box with a jet port was installed in the inside, and the hot air was sent to the inside of the nozzle box so that it might be jetted toward the fabric from the jet port. In order to perform efficient drying and heat treatment in such a dryer or a heat treatment machine, it is good to carry out as following (1) or (2) on condition of constant humidity and temperature in a cabin.

(1) Make the hot air blowing speed from the nozzle box ejection port as fast and uniform as possible. For example, when the blowing speed (wind speed) is increased from 10 m / sec to 20 m / sec, the fabric drying speed is about 1.7 times, and when it is raised from 10 m / sec to 30 m / sec, the drying speed is about 2.4 times.

(2) The distance between the fabric and the surface of the nozzle box is approached simply.

For example, if the distance between the fabric and the face of the nozzle box approaches 100mm to 50mm, the fabric drying speed is about 1.3 times, and if it approaches 100mm to 25mm, the drying speed is about 1.8 times.

In this type of conventional drying and heat treatment machine, an axial flow fan for directing hot air to the nozzle box 104 disposed at the upper and lower positions of the fabric F ', as shown in FIGS. Most of the fans 107 were provided on both sides of the body 126 to direct hot air from the nozzle box side.

Moreover, the nozzle box 104 is fixedly installed by the structure. In the case of this type of device, the upper and lower nozzle boxes 104 should be installed at locations where the guide rails 102 of the pin tenter 101 do not touch so as not to interfere with the adjustment of the spreading by the pin tenter 101. As a result, the distance between the fabric and the nozzle box surface increases, and even though the hot air blow-out speed is increased from the nozzle box, the force of the hot wind is weakened when the cloth comes into contact with the fabric, and thus the processing capacity cannot be improved.

In addition, in the fixed nozzle box, when the width of the fabric becomes narrower than the nozzle width, it becomes uneconomical as the useless hot air is emitted.

In order to make up for this drawback, an air trunk is connected to the axial flow fan that sends hot air, and the nozzle box protrudes from the opposite side of the air bag and fabric. It has been proposed to have a scoping-fitting configuration in which the effective width of the nozzle box is adapted to the width of the fabric to be treated by sliding adjustment of the box structure.

In the case of such a teleskoff type nozzle box, the hot air supply opening for the nozzle box is set so as to be smaller than the minimum effective width of the nozzle box on the opposite side of the fabric face so as not to be affected by the slide adjustment of the box structure. It is.

Therefore, the hot air sent from the hot air supply port by the fan is strong in the vicinity of the hot air supply port in the nozzle box, and the wind pressure is weak at both ends away from the hot air supply port. The speed is faster in the central part facing the hot air supply port, and slower as it gets closer to the end, so that it is not uniformly dried or heat treated, and further, it is impossible to increase the processing capacity.

In addition, in this type of dry heat treatment machine, the required length in the longitudinal direction of the gas (for example, 1.5 m) is divided into several blocks in consideration of the overall length of the machine and the ability of the fan. If the nozzle box spacing is wider than the other at the boundary of each block, as in the conventional machine shown in FIG. 2, confusion occurs in the wind pressure ejected from the nozzle box at this point, and the fabric is broken. ) May be sagging or shaken up or down, causing stains during treatment.

In order to rectify this defect, it is recommended that all nozzle boxes be equally spaced and installed as small as possible, but a screw shaft for adjusting the extruder of the pin tenter 101 holding the fabric F 'is provided. Since 115) is provided using the nozzle box spacing of the said block boundary part, it is necessary to set it as the structure which considered the existence of this screw shaft 115.

The present invention has been made in view of such a point, and its first object is to be constructed with a telescoping nozzle box from a hot air supply port provided on the opposite side to an opposite surface of a strip-shaped object to be treated into the nozzle box. It is an object of the present invention to provide a dry heat treatment apparatus of fabrics having a uniform air pressure in a nozzle box, having a means for actively distributing the hot air sent throughout the nozzle box.

That is, the present invention is characterized by including an inner nozzle for dispersing hot air sent from the hot air supply port in the nozzle box. Moreover, another object of the present invention related to the above is that the upper and lower bands of cloth-like strips having to deal with the nozzle box of the above-described configuration having a wide cross section having a wide cross section and having an inner nozzle in the opposite side of the strip-shaped water are provided. It is to provide a dry heat treatment machine for fabrics arranged in the same width over the entire length of the machine and arranged the screw shaft for adjusting the width of the retaining member to maintain the strip in the gap of the nozzle boxes adjacent to each other where necessary.

In the fabrication and heat treatment apparatus of the fabric of the present invention having the above structure, hot air sent into the telescoping nozzle box is dispersed by the inner nozzle, so that there is no difference in the wind pressure, and hence hot air blowout from the nozzle box. As the speed becomes uniform, the fabric is dried and heat-treated to improve staining.

In addition, by arranging the nozzle boxes at the same intervals, it is possible to eliminate the confusion of hot air blowing wind pressure and the excessive increase or flapping of fabric.

In addition, since the nozzle box is substantially trapezoidal in cross section with a wide width of the opposing face of the strip, the distance between the nozzle boxes gradually widens from the opposite side of the strip, and in the middle part, for adjusting the width of the strip holding member. Even if the screw shafts are spaced enough to be arranged, they are considerably narrower on the opposite side as described above, so that the floating effect due to the hot wind is improved, and the floating effect and the above-mentioned confusion prevention effect of the wind pressure are combined. We can send cloth-like strip form in well-organized state. Therefore, it is possible to speed up the hot air blowing and to approach the distance between the fabric and the face of the nozzle box without any problems, thereby increasing the efficiency and increasing the processing capacity. Embodiments of the present invention will be described with reference to the drawings.

In Fig. 3 to Fig. 11, (F) is a strip-like material to be treated with cloth, and (1) is an endless holding member such as a pin tenter provided in a pair of left and right, and the end of the strip-shaped material (F) is removed. Keep it and send it continuously. (2) is a guide rail of the holding member (1), (3) is an air cylinder disposed above and below the band-like material (F), and (4) extends in the width direction of the band-like material (F) and a band-shaped material ( A nozzle box having an appropriate number of ejection openings 5 on the opposite surface to F). The nozzle box 4 is provided in parallel in the direction to which the strip | belt-shaped object is sent to the opposite surface side with the strip | belt-shaped object F of the air container 3 mentioned above.

(6) is a hot air supply port for sending air from the reservoir (3) to the nozzle box (4). The ejecting side of the axial fan 7 is directly connected to approximately the center of the side opposite to the side to which the nozzle box of the air cylinder 3 is attached. The axial fan 7 supplies the hot air heated by the heaters 8 installed on both sides thereof into the air chamber 3 and from the hot air supply port 6 via the air cylinder 3 to the nozzle box 4. The hot air is sent inwards and blown out from the blower outlet 5 toward the strip | belt-shaped object (F).

The hot air blown out from the jet port 5 flows toward the nozzle box, flows both parts of the aircraft upward or downward, and is then sent by the axial fan 7 through the heater 8.

Therefore, the hot air is sent through the circulation method. Denoted at 9 is a brake provided above and below each part of the cabin so as to adjust the total blowing amount from the upper and lower nozzle boxes 4, and 10 is an air filter.

In addition, the nozzle box 4 has a configuration in which ten boxes are fitted in a three-piece structure 4a, 4b, and 4c so that the nozzle box 4 can expand and contract in the width direction of the strip-shaped material F. 4b) is fixed so as not to move, and the box structures 4a and 4c at both ends fitted to move therein are provided for slide adjustment.

The effective width of the nozzle box 4 can be easily adapted to the width | variety of the strip | belt-shaped object F which should process by sliding adjustment of this box structure 4a, 4c.

11 is a slide guide which supports the box structure 4a, 4c so that it can slide.

The ejection openings 5 on the opposite surfaces of the box members 4a, 4b, and 4c of the strip-shaped material F of the respective box structures 4a, 4b, and 4c have a length necessary for the slide direction to maintain the opening state regardless of the slide adjustment. It is formed in a slit shape.

The hot air supply opening 6 is set smaller than the minimum effective width of the nozzle box 4 so as to be within the range of the nozzle box 4 in the state in which the nozzle box 4 is minimized.

The nozzle box 4 is formed in a substantially trapezoidal cross section in which each of the box members 4a, 4b, and 4c has a wider width toward the strip-shaped object F as shown in the drawing.

Therefore, the gap between the nozzle boxes 4 adjacent to each other becomes narrow on the side toward the band-shaped material F, and the hot air blown out from the nozzle box 4 between the nozzle nozzles 4 in contact with the band-shaped material F. Since the flow into the space of is regulated by the narrow gap described above, the inequality effect of the band-like article F due to the hot air becomes good. Moreover, the inner nozzle 12 which distributes and blows the hot air sent from the hot air supply port 6 to the static area inside the nozzle box 4 is provided in the inside of the nozzle box 4.

The inner nozzle 12 may be of any type as long as it can distribute and blow hot air as described above, but has a hole plate having a porosity of 50% or less having multiple holes as shown in the drawings. Iv) The cross section corresponding to the nozzle box 4 is substantially trapezoidal, and both ends are formed in an open state, and as an attachment means, it is fitted to the edge portion of the hot air supply port 6 as shown in the drawing. You can attach or do other things.

Of course, there is a slight gap between the nozzle box 4 and the inner nozzle 12 so as not to interfere with the distribution of hot air. According to the above-described configuration, the hot air from the hot air supply port 6 first touches the inner nozzle 12 made of a hole plate, and a part of the hot air passes through the hole 13 of the inner nozzle 12 at the same time. The other ones are sent from both open ends of the inner nozzle 12 toward both ends of the nozzle box 4, and as a result, are evenly distributed throughout the entire corner of the nozzle box 4, so that the air pressure is uniform.

In addition, the shape and size of the hole 3 drilled in the inner nozzle 12 are not limited only to what was shown in drawing.

의 가이드(14a)(14b)(14c)가 형성되어 있다.In addition, each box structure 4a, 4b, 4c of the telescoping nozzle box 4 described above has a concave-convex line in the longitudinal direction fitted to each other on the opposing surfaces of the strips F.

Guides 14a, 14b and 14c are formed.

As the guides 14a, 14b and 14c described above, as shown in the drawing, the center of the opposite surface of the strips F of the box members 4a, 4b and 4c in the inward direction is formed by pressing or the like. It is most suitable that the groove is shaped like a groove.

In this case, the guides 14a, 14b, and 14c have rib reinforcement, and are excellent in preventing the distortion or deformation of the nozzle box 4, and at the same time, adjusting the slides of the box members 4a and 4c. This is done smoothly and well.

Furthermore, the upper and lower nozzle boxes 4 constituted as described above are attached to the air cylinders 3 corresponding to one block, respectively, but are arranged at equal intervals, including the boundary portions of the air cylinders 3, in particular, over the entire length of the machine. It is. And the screw shaft 15 for adjusting the spreading of the holding member 1 which supports the floating object F is arrange | positioned in the space | interval of the nozzle boxes 4 adjacent to each other where needed.

The arrangement interval of the nozzle box 4 described above is preferably set such that the ejection openings 5 in the nozzle box 4 are arranged at approximately the same interval in the direction in which the strip is sent.

In this way, when the nozzle boxes 4 are arranged at the same interval, confusion does not occur in the blowing wind pressure of the hot air from the nozzle box 4, and thus the strip F is sent squarely due to the floating effect of the hot air. .

In addition, in the shape of the nozzle box 4, the interval becomes wider from the opposite side of the band-like article F, and thus, even if the opposite side of the band-shaped article F is narrow, the screw shaft 15 is provided within the gap. You can do it together.

The support shaft 16 of the guide rail 2 is screwed into the screw shaft 15, and the guide rail 2, that is, the holding member 1, is inserted by inserting the support member 16 by the rotation of the screw shaft 15. Tumbler adjustment is made.

As the attachment means of the nozzle box 4, the nozzle box 4 may be directly attached to the cover plate on the opposite surface of the strip-shaped material F of the air cylinder 3, but as shown in the drawing, the hot air supply port Each box structure 4a, 4b, 4c, the slide guide 11, and the inner nozzle 12 are mounted on a substrate 17 of the required width where the 6 is formed, and this is provided with respect to the air cylinder 3. It is desirable to attach so that it can be removed.

That is, in this case, each nozzle box 4 can be attached and separated for each substrate 17 one by one, so that maintenance and replacement are easy.

In addition, as described above, the telescoping-type nozzle box 4 can fit the effective width to the width of the strip-shaped material F, so that the gap between the opposing surfaces of the upper and lower nozzle boxes 4 is left and right as shown in the drawing. It can be set smaller than the width (thickness) of the guide rail 2 in the up-down direction, and the distance between the strip | belt-shaped object and the surface of the nozzle box 4 can be approached.

Further, the box structures 4a and 4c and the guide rails 2 can be connected to each other so that the slide adjustment of the box structure can be linked to the adjustment of the width of the holding member 1.

In this case, the ends of the strip-shaped material F to be treated tend to lack contact with the hot air due to the holding member 1 supporting the portion, so that both ends of the nozzle box 4 are supplemented to compensate for this. It is advisable to install a structure to increase the airflow in the air.

As the structure for increasing the blowing amount, as shown in the drawing, it is possible to form an auxiliary jet port 5 'or to expand the diameter of the end of the original jet port 5, and the like.

Further, in the above structure, the upper and lower air cylinders 3 combine two parts 3a and 3b, which are separate bodies of the axial fan connection side and the nozzle box attachment side, respectively, by bolts or the like, and at the nozzle box attachment side, respectively. It is recommended to install (3a) to move up and down using a long hole fitted with bolts.

That is, in this case, the gap between the opposing surfaces of the upper and lower nozzle boxes 4 can be adjusted, and when the gaps described above are inspected and cleaned, the nozzle box is made larger than the width of the upper and lower directions of the guide rails 2. The dismantling work in 4) can be facilitated. The axial fan 7 also has a wing wheel 21 having several movable wings 20 tied to a drive shaft 19 in a casing 18 and movable wings of the wing wheel 21. It is provided with a guide blade 22 close to the blowing side with respect to.

In particular, the guide blade 22 is shaped so that the helical flow in the axial direction due to the rotation of the blade wheel 21 is rectified in a straight flow in two directions in the axial direction and the rotation direction. The other two kinds of fixed blades 23a and 23b are provided with horn-shaped fixed blades each on the inner and outer surfaces of 24, and the horn-shaped fixed blades described above are the diameter of 24. This small part is located between the casing 18 and the hub cab 25 to approach the movable wing 20 of the wing wheel 21, and the larger diameter part is the casing. It is installed so that it is located outside (18).

Since the axial fan 7 is connected directly to the air cylinder 3 which is larger than this, the discharge side of the axial fan 7 has a larger diameter of the horn-shaped fixed wing 24 in the guide vane 22 described above. It is located in the air cylinder 3, and sends hot air far from the fan in the air cylinder 3, and the guide vane 22 mentioned above acts effectively.

That is, the hot air sent out from the axial fan 7 is rectified by the guide vane 22 in a straight stream in two directions in the axial direction and the rotational centrifugal direction, and is sent to the entire area of the air cylinder 3. Therefore, the hot air supply to each nozzle box 4 attached to the air cylinder 3 is made uniform, and further the uniformity of the hot air blowing rate can be attained.

In the above drying and heat treatment apparatus, as shown in FIG. 11, if both surfaces of the base 26 are formed in the door system according to the door 27 provided for each block corresponding to the length of the air cylinder 3, the inside of the cabin Maintenance and inspection can be facilitated.
