As illustrated, the molding apparatus of the compression sheet for manufacturing the foam mat of the present invention is largely composed of an extrusion roller 10 , a fluid supply pipe 20 , an injection pipe 30 , and a controller 40 .

The extrusion roller 10 of the present invention is configured to include an upper roller 11 and a lower roller 12 that are provided with each other at a predetermined gap on the same vertical line.

These upper rollers 11 and lower rollers 12 are made of hollow cylinders, and each of these upper rollers 11 and lower rollers 12 has one end of both ends of the rotating shaft 13 by means of a belt or gear connection. connected so that the upper roller 11 and the lower roller 12 rotate in opposite directions to each other.

In other words, at both ends of the upper roller 11 and the lower roller 12, the rotating shaft 13 is shaft-fixed, and these rotating shafts 13 are rotatably supported by bearing coupling to the support 14 on both sides. make it possible

A sprocket or a gear is respectively connected to one of the rotation shafts 13 on both sides supported by the support 14, and a sprocket or gear and a belt or gear shaft fixed to the drive shaft of the motor (not shown). to be combined.

The fluid supply pipe 20 is connected to the other rotation shaft 13 among the rotation shafts 13 on both sides.

The fluid supply pipe 20 includes a steam supply pipe 21 for supplying steam and a cooling water supply pipe 22 for supplying cooling water, and these fluid supply pipes 20 include an upper roller 11 and a lower roller of the extrusion roller 10 . (12) respectively.

That is, the fluid supply pipe 20 including the steam supply pipe 21 and the cooling water supply pipe 22 allows steam or cooling water to be supplied through the steam supply pipe 21 and the cooling water supply pipe 22, and the steam or cooling water selectively supplied in this way. is connected to the upper roller 11 and the lower roller 12 through a single tube.

On the other hand, the upper roller 11 and the lower roller 12 are provided with an injection tube 30, respectively, and the injection tube 30 is inserted through the rotation shaft 13 and rotated through the upper roller 11 and It is configured to be fixedly installed so as not to rotate with respect to the lower roller 12 .

That is, the injection pipe 30 passes through the rotation shaft 13 that is rotatably supported by a bearing coupling on one side of the support 14 on each side of the upper roller 11 and the lower roller 12, and the upper roller ( 11) and the center of the lower roller 12.

However, the injection pipe 30 is configured such that one end is fixed to the support 14 on one side, and the other end is axially supported by a bearing coupling at the other end of the upper roller 11 and the lower roller 12 .

Accordingly, one end is mounted on one side of the support 14 so that the rotation shaft 13 on both sides of the support 14 is not relatively rotated inside the upper roller 11 and the lower roller 12, which are rotatably supported by a bearing coupling. This is fixedly coupled, and the other end is rotatably supported by a bearing coupling at the ends of the upper roller 11 and the lower roller 12 corresponding thereto, so that even when the upper roller 11 and the lower roller 12 rotate. The injection pipe 30 is not rotated so that the fixed state is stably maintained.

Meanwhile, at the end of the injection pipe 30 , the steam supply pipe 21 and the cooling water supply pipe 22 meet at the same time.

However, the steam supply pipe 21 and the cooling water supply pipe 22 are connected to the injection pipe 30 of the upper roller 11 and the lower roller 12, respectively, so that the temperature of the upper roller 11 and the lower roller 12 is Controls can also be made individually.

The nozzle 31 is formed radially along the outer circumferential surface as shown in FIG. 3 in the injection pipe 30 provided inside the upper roller 11 and the lower roller 12, respectively, so that steam or By allowing the coolant to be sprayed, the temperature of the upper roller 11 and the lower roller 12 can be adjusted by the sprayed steam or coolant.

The nozzle 31 formed on the outer circumferential surface of the injection pipe 30 is sprayed toward the inner circumferential surface of the upper roller 11 and the lower roller 12 along a predetermined interval from the outer circumferential surface, so that the upper roller 11 and the lower roller 12. This is to keep the temperature constant so that it does not overheat.

Meanwhile, the controller 40 of the present invention checks the temperature of the upper roller 11 and the lower roller 12 of the extrusion roller 10 to intermittently control the supply of steam or cooling water supplied through the fluid supply pipe 20 . is the composition

That is, the steam supply pipe 21 and the cooling water supply pipe 22 of the fluid supply pipe 20 selectively supply steam or cooling water to the injection pipe 30 so that the temperature of the upper roller 11 and the lower roller 12 is constant. to be maintained as a range.

Therefore, the controller 40 supplies heated steam through the steam supply pipe 21 so that the dough extruded through the extrusion roller 10 is spread to a certain thickness while maintaining a certain viscosity by rolling.

When the upper roller 11 and the lower roller 12 try to overheat, the steam supply is cut off and the cooling water is supplied through the cooling water supply pipe 22, thereby quickly lowering the temperature of the upper roller 11 and the lower roller 12. Cool to avoid overheating.

However, the upper roller 11 and the lower roller 12 are each provided with an outlet 15 through which the coolant is discharged to one side of the lower surface.

The molding apparatus of the compression sheet for manufacturing a foam mat of the present invention according to the above configuration is an extrusion roller 10 through the steam supply pipe 21 in a state that the cooling water supply on the cooling water supply pipe 22 side of the fluid supply pipe 20 is first blocked. The heated steam is supplied to the injection pipe 30 of the upper roller 11 and the lower roller 12 of the .

The upper roller 11 and the lower roller 12 reach the desired temperature very quickly by the heated steam, and the raw materials are mixed and mixed as shown in FIG. 4 through the gap between the upper roller 11 and the lower roller 12. The dough 50 made by the is pushed in so that the sheet 60 is molded to a predetermined thickness by rolling.

The temperature of the upper roller 11 and the lower roller 12 heated by steam heat is checked by the controller 40 so that when the checked temperature exceeds a certain range, the steam supply is automatically cut off while cooling water is supplied. By allowing it to be cooled quickly, the extrusion roller 10 can always maintain a temperature within a certain range.

That is, the temperature control of the extrusion roller 10 using steam and cooling water is performed very quickly, and the temperature can be stably maintained.

In addition, as shown in FIG. 5 , the gap between the upper roller 11 and the lower roller 12 of the extrusion roller 10 is gradually narrowed so that the thickness of the previously formed sheet 60 can be formed to be thinner. .

As described above, in order to produce a sheet of thin plate produced in the process for manufacturing the foam mat to a desired thickness, it is difficult to form by one rolling, so that the gap between the upper roller 11 and the lower roller 12 is gradually narrowed. Since the rolling has to be repeated several times, temperature control of the extrusion roller 10 is very important for forming a sheet having a desired thickness and hardness. By making this possible, it becomes possible to significantly improve the sheet manufacturing yield.

Therefore, the extrusion roller 10 provided for forming a sheet of a thin plate for manufacturing the foam mat of the present invention is overheated by the extrusion roller 10 by selectively supplying high-temperature steam or cooling water to control the temperature very quickly. Prevents accidents such as interruption of process execution due to

By this stable temperature control, it is possible to minimize the amount of the plasticizer that is harmful to the environment, which is added to prevent the raw material from burning, so that more eco-friendly manufacturing is possible.

In addition, since it is possible to form a lighter sheet by minimizing the capacity of the plasticizer, it is possible to manufacture the foam mat in a lighter weight.

As such, the present invention is not limited to the described embodiments, and it is apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the present invention. Accordingly, it should be said that such modifications or variations shall fall within the scope of the claims of the present invention.
