Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [Forming apparatus of compressing seat for manufacturing forming mat]

The present invention relates to an apparatus for forming a pressing sheet for manufacturing a foam mat, and more particularly, the upper and lower portions for pressing the sheet to form a desired thickness and viscosity while forming a thin film compression sheet for manufacturing a foam mat. It relates to an apparatus for forming a pressing sheet for manufacturing a foam mat in which the temperature of the pressing roller is controlled by steam and cooling water.

In general, on the floors of gymnasiums, gyms, kendo centers, judo centers, kindergartens, etc., foam mats (sheets) made of elastic material are laid to minimize the impact on the floor so that the facility can be safely used and injuries to the body can be prevented.

In particular, when the foam mat is installed in an exercise facility, it has a certain repulsive force due to the elasticity of the mat, so it greatly reduces the risk or risk of injury, so that it can exert the maximum exercise effect without exerting a strain on the joints or muscles. There will be.

Such a foaming mat is usually mixed with various additives including a foaming agent, an auxiliary agent, an accelerator, a filler, etc. to a resin or rubber or a mixed main raw material, and then compressed to produce a mat having a predetermined thickness.

In order to manufacture a foam mat, a plurality of foam sheet papers are laminated and then pressed to foam. Such foam sheets are made to be compressed while passing through a pressing roller provided above and below a raw material kneaded to a certain viscosity. Are doing.

The kneaded raw material changes its viscosity while performing the process, and in order to extrude a foam sheet having a certain thickness, it is necessary to maintain a certain temperature during compression in order to maintain the viscosity.

In order to form the foam sheet, a pair of pressing rollers provided up and down on the same vertical line is allowed to pass through the dough material, and the sheet that has already been pressed to a certain thickness must be pressed again to form the desired thickness.

A separate plastic material is sometimes added for the molding of the pressing sheet, but in order to maintain a certain viscosity of the sheet passing through the pressing roller, the pressing roller is provided with a heating means for heating to a certain temperature.

The heating means applied to the pressing roller is generally applied as a structure in which the heater is heated inside each pressing roller by an external power source so that the pressing roller is heated.

However, in some cases, a configuration in which water, which is a heating fluid, is heated from the outside to circulate the inside of the compression roller is applied, but such a heating structure must be provided with a compression roller having a very complex internal structure, making it difficult to use in practice. There is this.

However, in the case of a pressing roller using an electric heater, a specific plasticizer must be used to prevent overheating of the temperature. In addition, when the plasticizer is added, the effect on the properties of the raw material must be considered, and it is not easy to control the heating temperature.

1 is a front view schematically illustrating an apparatus for forming a pressing sheet for manufacturing a foam mat according to the present invention, and FIG. 2 is a cross-sectional plan view illustrating the internal structure of a roller in the apparatus for forming a pressing sheet for manufacturing a foam mat according to the present invention.

As illustrated, the molding apparatus of the pressing sheet for manufacturing a 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 composed of an upper roller 11 and a lower roller 12 which are mutually provided with a predetermined gap on the same vertical line.

These upper rollers 11 and lower rollers 12 are made of an empty cylindrical shape, and each of the upper rollers 11 and lower rollers 12 has one end of the both ends of the rotating shaft 13 by belt or gear connection. By connecting the upper roller 11 and the lower roller 12 to rotate in opposite directions to each other.

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

Sprockets or gears are connected to one of the rotational shafts 13 on one side of the rotational shafts 13 on both sides supported by the support 14, and a sprocket or gear and a belt or gear fixed to the drive shaft of a motor (not shown) To be combined.

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

The fluid supply pipe 20 is composed of a steam supply pipe 21 supplying steam and a cooling water supply pipe 22 supplying cooling water, and these fluid supply pipes 20 are the upper roller 11 and the lower roller of the extrusion roller 10. Each is provided in (12).

That is, the fluid supply pipe 20 composed of the steam supply pipe 21 and the cooling water supply pipe 22 allows steam or cooling water to be supplied by the steam supply pipe 21 and the cooling water supply pipe 22, and thus selectively supplied steam or cooling water Is connected to the upper roller 11 and the lower roller 12 through one tube.

On the other hand, the upper roller 11 and the lower roller 12 are provided with injection pipes 30, respectively, and the injection pipe 30 is inserted through the rotation shaft 13 through the upper roller 11 and rotates It is a configuration that is fixedly installed so as not to rotate with respect to the lower roller 12.

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

Therefore, one end of the support 14 on one side so that the rotation shaft 13 on both sides of the support 14 does not rotate relatively inside the upper roller 11 and the lower roller 12, which are axially supported so as to be rotatable by bearing coupling. This is fixedly coupled, and the other end is rotatably supported by bearing coupling at the ends of the upper roller 11 and the lower roller 12 corresponding thereto, so that even if the upper roller 11 and the lower roller 12 rotate The injection pipe 30 does not rotate and is kept in a fixed state stably.

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

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 It is also possible to have individual control.

In the injection pipe 30 provided inside the upper roller 11 and the lower roller 12, respectively, a nozzle 31 is formed radially along the outer circumferential surface as shown in FIG. By allowing the cooling water to be sprayed, the temperatures of the upper roller 11 and the lower roller 12 can be controlled by the sprayed steam or cooling water.

The nozzles 31 formed on the outer circumferential surface of the injection pipe 30 are sprayed from the outer circumferential surface toward the inner circumferential surfaces of the upper roller 11 and the lower roller 12 at a predetermined interval, so that the upper roller 11 and the lower roller 12 It is to maintain a constant temperature so that it does not overheat.

Meanwhile, the controller 40 of the present invention controls the supply of steam or cooling water supplied through the fluid supply pipe 20 by checking the temperatures of the upper roller 11 and the lower roller 12 of the extrusion roller 10. Configuration.

That is, the steam supply pipe 21 and the cooling water supply pipe 22 of the fluid supply pipe 20 allow the temperature of the upper roller 11 and the lower roller 12 to be constant by selectively supplying steam or cooling water to the injection pipe 30. To keep it 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 reducing the temperature of the upper roller 11 and the lower roller 12. Cool to prevent overheating.

However, the upper roller 11 and the lower roller 12 are provided with outlets 15 through which cooling water is discharged to one side of the lower surface, respectively.

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

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 between the gaps between the upper roller 11 and the lower roller 12. The dough 50 made by is pushed so that the sheet 60 is molded to a predetermined thickness by rolling.

The dough 50, which passes between the upper roller 11 and the lower roller 12 heated to a certain temperature by steam supply, is pressed to a desired thickness, while making the dough a suitable viscosity and not easily cured even after pressing. Avoid.

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

That is, the temperature control of the extrusion roller 10 using steam and cooling water is not only performed very quickly, but also 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. .

In this way, in order to produce a sheet of thin plate produced in the process of manufacturing a foam mat to a desired thickness, it is difficult to form the sheet by one rolling, so that the gap between the upper roller 11 and the lower roller 12 is gradually narrowed. Since the rolling must be repeated a plurality of times, temperature control of the extrusion roller 10 is very important for sheet forming with the desired thickness and hardness, but this temperature control is performed by steam heat and cooling water, allowing quick and accurate control even during process execution. By making it possible, the yield of sheet manufacturing can be significantly improved.

Therefore, the temperature control of the extrusion roller 10 provided for sheet molding of a thin plate for manufacturing the foam mat of the present invention is made very quickly by selective supply of hot steam or cooling water, thereby overheating the extrusion roller 10 It prevents accidents such as interruption of process execution according to the result, and makes it possible to perform a stable process.

Such a stable temperature control makes it possible to minimize the capacity of the plasticizer that is harmful to the environment to be added to prevent the raw material from burning, so that more environmentally friendly manufacturing is possible.

In addition, by minimizing the capacity of the plasticizer, a more lightweight sheet can be formed, so that the foam mat can be manufactured with a lighter weight.

As described above, the present invention is not limited to the described embodiments, and it is obvious to those of ordinary skill in the art that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, it should be said that such modifications or variations belong to the claims of the present invention.
