Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a cloth dryer that has been subjected to a chemical or glue treatment such as a guard treatment.

(Prior Art) Conventionally, this type of cloth dryer has a plurality of heating rotary drums 33, 34, 35 mounted vertically on a support 32 installed on an open base 31, as shown in FIG. The undried cloth 36 is rotatably supported and immersed in a glue or chemical liquid, and is rolled into a depressing roll 37.
each heated rotating drum 33, 34, 3.
5, the fabric 36 was grounded in a wavy manner and dried by heating.

(Problems to be Solved by the Invention) However, the conventional cloth dryer is completely open and has no exhaust means.
There was a problem in that the exhaust gas and moisture emitted from the cloth 36 treated with chemicals or glue, which gradually dried in the heated rotating drums 33, 34, and 35, remained in the work chamber. In addition, when gold or silver is attached to the surface of the cloth 36, the cloth 36 is attached to each heating rotating drum 33, 34, 35 from the back side to the front side.
There was a problem in that the back surface and the ground were alternately connected, and the front surface of the cloth 36 came into contact with the surface of the heating rotating drum 34, making it easy for the glue with gold and silver attached to it to come off.

The present invention was developed by focusing on this problem, and involves drying cloth treated with chemicals or glue by winding it around the circumferential surface of a heated rotating drum, and using a suction blower to remove the exhaust gas generated during drying. In addition to expelling moisture to the outside and speeding up the drying of fabrics,
It is an object of the present invention to provide a fabric dryer that is free from the risk of detachment of glue adhering gold and silver.

(Means for Solving the Problems) In order to solve the above conventional problems, the fabric dryer according to the present invention is constructed as follows.

A heating rotary drum is rotatably supported in a casing provided with an inlet and an outlet for cloth.

The cylindrical body is fixed with a narrow annular gap formed between the cylindrical body and the outer peripheral surface of the heating rotating drum.

This cylindrical body is provided with an inlet portion and an outlet portion corresponding to the inlet and outlet ports, respectively, and a suction blower is communicated with a hole provided in the lower peripheral surface of the cylindrical body.

A discharge pipe with one end protruding outside the casing is connected to the suction blower, and a plurality of guide rolls are rotated within the annular gap from near the inlet to the outlet on the other side. Freely pivot.

Furthermore, a depression roll is arranged inside the casing near the inlet.

(Function) Since the present invention is configured as described above, the fabric soaked in a liquid such as a glue or a drug is guided into the cylinder from the inlet through the dip roll.

The heating rotary drum, which forms an annular gap between the heating rotary drum and the cylindrical body, is then brought into contact with the heating rotary drum by winding it in a large manner from the upper circumferential surface downwardly over approximately one circumference to effect sufficient hot air drying.

The moisture and exhaust gas generated at this time are rapidly removed from the surface of the cloth by the action of the suction blower, increasing the drying effect, and furthermore, the dehumidification and drying process using strong winds combined with hot air drying ensures sufficient drying. The cloth is reversed by a guide roll disposed near the inlet, and further moved by the guide roll through the intermediate space below the annular gap toward the discharge port.

At this time, dry outside air is sucked from the inlet and outlet, rapidly flows through the lower part of the gap, and is sucked into the hole in the lower peripheral surface of the cylinder by a suction blower, making it continuously contact both sides of the fabric. , remove any residual moisture, quickly and reliably dry the fabric, and take it out from the outlet.

In the dehumidifying and drying process combined with hot air drying, most of the glue,
The chemicals, etc. are dried and integrated with the cloth, so even if the cloth is turned over and the surface of the cloth comes into contact with the guide roll, the drying process can be carried out smoothly without the risk of the gold, silver, etc. contained in the glue coming off. Let's do it. Furthermore, moisture and exhaust gas are forcibly exhausted to the outside using a suction blower.

(Example) An example of implementing the present invention will be described in detail with reference to the drawings.

An undried piece of cloth 2 is placed on one side above the casing 1.
An inlet 3 is opened for the casing 1, and an outlet 4 for the dried cloth 2 is opened at the other side of the upper side of the casing 1. A heating rotary drum 5 for drying the cloth 2 while being rolled and transported is rotatably supported inside the casing 1, and a gap narrower than the peripheral surface of the heating rotary drum 5 is provided on the outer peripheral side of the heating rotary drum 5. Preferably 5~
A cylindrical body 7 concentric with the heating rotating drum 5 is provided with an annular gap 6 of 10 cm.

An inlet portion 9 is opened on one side of the cylinder 7 for guiding the cloth 2, which has advanced from the introduction port 3 through the dip roll 8, toward the heating rotating drum 5 and winding it thereon. Further, on the other side of the cylinder 7, there is an outlet portion 10 of the cloth 2 in contact with the outlet 4.
is open. Further, a suction blower 12 is communicated with a hole 11 formed in the lower peripheral surface of the cylinder 7, and the other end of a discharge pipe 13, one end of which projects outside the casing 1, is connected to the suction blower 12.

Note that an exhaust pipe for exhausting the air outside the working chamber is connected to this exhaust pipe 13, but it is omitted in the drawing.

Furthermore, a heating rotating drum 5 is provided inside the cylinder 7.
In order to widen the ground contact area of the cloth 2 on the heating rotary drum 5, the cloth 2 wound up to one side upper part of the heating rotary drum 5 is reversed from that position and advanced to the outlet section 10. A plurality of guide rolls 14, 14', 1 are provided in the gap 6 between 5 and the cylinder 7.
4'' is rotatably supported, and the outlet portion 10
A guide roll 15 is attached to the bottom of the casing 1 for discharging the cloth 2 to the outside of the casing 1.

As an auxiliary drying means to the drying means using the heated rotating drum 5, a fan 16 is installed inside the upper part of the inlet 9 provided on one side of the cylinder 7 to blow air in the direction of movement of the cloth 2. Together with the cylinder body 7
If a fan 17 is attached to the inside of the upper part of the outlet section 10 provided on the other side so as to blow air obliquely downward toward the fabric 2 wound around the heated rotating drum 5, the drying effect can be further improved. be able to. In this case, the suction blower 12 needs to have a stronger suction force than the fans 16 and 17.

In the figure, reference numeral 18 denotes a sprayer attached to the inner wall of the inlet 3 of the casing 1, and the paste or medicine can be sprayed onto the fabric 2 from the sprayer 18. This spray 18
If you do not have one, soak the cloth 2 in a glue or chemical liquid beforehand and squeeze it with a dip roll 8.
Further, 19 is a feed roll.

When using the fabric dryer of the present invention having the above-described configuration, the undried fabric 2 immersed in the glue or chemical solution is squeezed by the dip roll 8 and passed through the inlet section 9. It enters the cylinder body 7,
Alternatively, the fabric 2 that has been sprayed with glue or medicine by the atomizer 18 in the casing 1 enters the cylinder 7 through the inlet portion 9. The cloth 2 is then wound around the heated rotating drum 5 to one side, reversed by the guide roll 14, passed through the guide rolls 14' and 14'', and then discharged to the outside of the casing 1 via the guide roll 15 of the discharge port 4. At this time, the cloth 2 wound around the heating rotating drum 5 has a wide contact area with the heating rotating drum 5, and the narrow gap 6 between the heating rotating drum 5 and the cylinder body 7 is a type of It functions as a duct and sucks exhaust gas, moisture, etc. generated during drying in the gap 6 through the suction blower 12 and discharges it to the outside for drying.

In addition, when gold or silver is attached to the surface of the cloth 2 via a glue, the back surface of the cloth 2 is wound up to one side above the heating rotating drum 5, so the ground contact area becomes large. In the meantime, cloth 2 has dried sufficiently,
It is reversed by the guide roll 14 and the discharge port 14, 14'
14", the glue will not come off even if the gold and silver are attached to the ground. When the heated rotating drum 5 cannot dry the cloth 2 sufficiently, the fans 16 and 17
When the suction blower 12 is rotated, the suction force of the suction blower 12 is stronger than that of the fans 16 and 17, so the gap 6 becomes a negative pressure, and exhaust gas and moisture are not discharged from the inlet 9 and the outlet 10. , by suctioning outside air from the outlet section 10 and blowing it in the direction of movement of the cloth 2 by the fans 16 and 17,
This allows the drying of the fabric 2 to be assisted by the heated rotating drum 5.

As described above, the present invention has a heating rotary drum 5 rotatably supported in a casing 1 which has an inlet 3 for the fabric 2 on one upper side and an outlet 4 for the fabric 2 on the other side. A cylinder body 7 is fixedly installed with a narrow annular gap 6 between the heating rotation and the outer peripheral surface of the drum 5, and the cylinder body 7 corresponds to the inlet port 3 and the discharge port 4, respectively. An inlet part 9 and an outlet part 10 are provided, and a suction blower 12 is communicated with a hole 11 bored in the lower peripheral surface of the cylinder 7, and one end of the suction blower 12 is made to protrude outside the casing 1. The other ends of the discharge pipes 13 are connected to each other, and a plurality of guide rolls 14 are provided in the annular gap 6 from near the inlet part 9 downward to the outlet part 10 on the other side.
14', 14'', and 15 are rotatably supported, and a dip roll 8 is disposed inside the casing 1 near the inlet 3. Therefore, the adhesive introduced into the casing 1 from the inlet 3, A heating rotary drum 5 is used which guides the fabric soaked in a liquid such as a drug into the cylinder 7 from the inlet 9 through the dip roll 8, and forms an annular gap 6 between it and the cylinder 7 as shown in FIG. Sufficient hot air drying can be carried out by making a large roll contact from the upper circumferential surface to the lower circumference, and the moisture and exhaust gas generated at this time can be rapidly removed from the cloth surface by the action of the suction blower 12. The guide roller 1 disposed near the entrance section 9 enhances the drying effect and further drys the fabric sufficiently through the dehumidifying and drying process using strong winds combined with hot air drying.
4, and while the guide rolls 14, 14'', and 15 move the intermediate space at the bottom of the annular gap 6 toward the discharge port 4, the lower part of the gap 6 is sucked from the inlet 9 and the discharge port 4, and the lower part of the gap 6 is moved. Dry outside air is rapidly flowed through the interior and sucked into the hole 11 on the lower peripheral surface of the cylinder 7 by the suction blower 12, and is brought into continuous contact with both sides of the fabric to remove any residual moisture and quickly and reliably remove the fabric. It can be dried and taken out from the outlet 4,
In addition, as described above, in the dehumidifying and drying process combined with hot air drying, most of the glue, chemicals, etc. are dried and integrated with the fabric, so it is turned over and moved to the guide rolls 14, 14',
Even if the surface of the fabric comes into contact with 14'' and 15, the drying process can be carried out smoothly without the risk of gold, silver, etc. contained in the glue coming off. Since exhaust gas is forced to the outside at 12, the work can be carried out comfortably without trapping exhaust gas or moisture in the casing 1 or other parts.
