A nozzle for manufacturing artificial marble according to the present invention is a nozzle for manufacturing artificial marble, which discharges a marble mixture to a base mixture being conveyed by a conveyance belt, comprising: a nozzle body having a discharge port for discharging a marble mixture; And a pair of guide plates extending from the nozzle body in the discharge direction of the marble mixture.

Description

TECHNICAL FIELD [0001] The present invention relates to a nozzle for manufacturing an artificial marble, and a manufacturing apparatus for the artificial marble including the nozzle for manufacturing the artificial marble.

The present invention relates to a nozzle for manufacturing artificial marble and an apparatus for manufacturing artificial marble comprising the same. More particularly, the present invention relates to a nozzle for manufacturing artificial marble, which is capable of forming regular and clear marbles constantly irrespective of change in viscosity or discharge pressure of the marble composition. Nozzle and an artificial marble manufacturing apparatus including the same.

Artificial marble is made by mixing additives such as natural stone powders, minerals and resin chips into a synthetic resin such as an acrylic resin, an unsaturated polyester resin and an epoxy resin, or a base such as cement, and adding additives such as pigments, Can be implemented.

Representative types of such artificial marble include acrylic artificial marble, polyester artificial marble, epoxy artificial marble, melamine artificial marble, and engineered stone artificial marble.

As described above, artificial marble has a beautiful appearance and excellent workability, and is advantageous in lightness and strength compared with natural marble, and is widely used as various interior materials.

Artificial marbles, which have been known up to now, have realized the appearance effect mainly through the combination of monochrome opaque chips.

However, in such a manner, there are limitations in realizing patterns similar to natural marble or granite in artificial marble. Therefore, much research is underway to develop artificial marble having an appearance similar to that of natural marble.

For example, in order to realize a pattern close to natural stone, conventionally, there has been known a method in which shapes of chips are diversified, resin mixtures of different colors are mixed or laminated in advance, and then an agitator is used. However, according to this method, there is a disadvantage in that it does not have a connective pattern possessed by natural stone. In case of using a dichroic resin mixture, there is a disadvantage in that there is no sharpness of the pattern of natural stone because of the smear caused by use of the same resin.

On the other hand, a method of making artificial marble is known as a marble compound for displaying a marble pattern and a base compound for forming an artificial marble. However, according to this method, due to the high specific gravity of the base compound, the marble compound necessary for pattern formation is buried and it is difficult to provide a clear pattern.

Related publications are disclosed in Korean Patent Laid-Open Publication No. 10-2008-0041501 (published on May 13, 2008), which describes a chip for artificial marble and a manufacturing method thereof.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a nozzle for manufacturing artificial marble which is capable of forming regular and clear marbles while being constant regardless of changes in viscosity or discharge pressure of the marble composition.

5 is a plan view of a nozzle for manufacturing artificial marble according to another embodiment of the present invention.
6 is a conceptual view showing an artificial marble manufacturing apparatus including a nozzle for manufacturing artificial marble according to an embodiment of the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

It is to be understood that the present invention is not limited to the disclosed embodiments, but may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, It is provided to inform.

FIG. 1 is a conceptual view showing a schematic structure of a general artificial marble manufacturing apparatus.

1, the artificial marble manufacturing apparatus 1 comprises a conveyance belt 10, a base mixture storage tank 20 for storing a base mixture (or a base compound) C1, a marble mixture (Hereinafter referred to as " marble compound ") C2.

The conveyance belt 10 is made of steel or the like and can be driven in one direction. However, the conveyance belt 10 is not limited thereto and may have different materials and driving forms. The base mixture storage tank 20 stores the base mixture C1 and supplies the base mixture C1 to the conveyance belt 10. A marble mixture storage tank 30 is located on the conveyance belt 10 behind the base mixture storage tank 30 and stores the marble mixture and supplies the marble mixture toward the base mixture. The nozzle 40 is installed on the conveyance belt 10 and serves to mix and discharge the marble mixture C2 to the base mixture C1. For this purpose, the nozzle 40 may have a structure connected to the connection line of the marble mixture storage tank 30. The curing device 50 corresponds to a device for producing artificial marble by curing a base mixture and a marble mixture which are mixed with each other by the action of the nozzle 40. However, according to the conventional method shown in FIG. 1, since the specific gravity of the base mixture is relatively high, it is difficult for the marble pattern, that is, the marble mixture necessary for forming the pattern, to be covered with the base mixture and to have a clear pattern through the appearance. In order to obtain a clear marble pattern, the viscosity of the marble mixture is set within a certain range. If the viscosity changes according to various factors such as seasonal changes, it may be difficult to achieve the target marble pattern.

SUMMARY OF THE INVENTION The present invention has been devised to solve such problems, and it is possible to produce uniform, thin, regular, and clear marble patterns by improving the shape and structure of the nozzles.

FIG. 2 is a perspective view showing a nozzle for manufacturing artificial marble according to an embodiment of the present invention, and FIG. 3 is a side view showing a nozzle for manufacturing artificial marble according to an embodiment of the present invention.

2 and 3, the illustrated artificial marble manufacturing nozzle 100 is a nozzle for discharging the marble mixture C2 to the base mixture C1 being conveyed by the conveyance belt 10, And a guide plate 120 (121, 123).

The nozzle body 110 may have a discharge port 130 for discharging the marble mixture C2.

As a specific example, the discharge port 130 may be formed in the same direction as the conveyance direction of the base mixture C1 through the conveyance belt 10.

The discharge port 130 may have a variety of shapes. The discharge port 130 may have a rectangular shape having a vertical height larger than that of the lateral width, as shown in FIG. 2, but is not limited thereto. As an example, the width of the discharge port may be 1.0 to 1.2 mm. If the width of the discharge port is larger than 1.2 mm, the flow rate of the marble mixture is lowered so that it can not be extended far. However, the width of the discharge port may vary depending on the size of the nozzle, so that it need not be limited to a specific value range.

Meanwhile, the nozzle body 110 may have a female threaded portion 111 through an inner peripheral surface in the form of a bolt. Thus, the nozzle body 110 can be connected to the supply line of the marble mixture storage tank 30 (see FIG. 6) by screwing. According to such a structure, the marble mixture supplied from the marble mixture storage tank 30 (see FIG. 6) may be introduced into the nozzle body 110 and then discharged through the discharge port 130 at a predetermined pressure.

The pair of guide plates 120 (121, 123) may be formed to extend in parallel to one direction of the nozzle body 110.

As a specific example, the pair of guide plates 120 (121, 123) are formed toward the discharge direction of the marble mixture C2 (or the transfer direction of the base mixture) with the discharge port 130 therebetween It is good.

The pair of guide plates 120 and 121 and 123 constitute a pair of guide plates 120 and 121 and 123. The pair of guide plates 120 and 121, In other words, it can play a role of providing a kind of buffer space.

The pair of guide plates 120 (121, 123) may be arranged side by side on the left and right sides of the discharge port 130 with the same interval therebetween.

Referring to FIG. 4, the pair of guide plates 120 (121, 123) may be connected to the nozzle body 110 in the same direction as the discharge port 130. Preferably, each of the pair of guide plates may be disposed in parallel with the discharge openings 130 at equal intervals, and each interval may be a half of the entire interval W.

Each of the pair of guide plates 120 and 121 and 123 may extend from the nozzle body 110 in the same direction toward the discharge direction of the marble mixture, that is, the direction in which the discharge port 130 is formed . If either one of the guide plates is relatively short, the marble mixture overflows to the short guide plate, which may make it difficult to form regular and uniform marble patterns.

The width of each of the pair of guide plates 120 (121, 123) may be 3.5 to 4.0 mm. When the width of the discharge port 130 is 1.0 to 1.2 mm, Means that a clearer and thinner marble pattern can be formed when the guide plate is provided in the form of a plate.

3, the height of each of the pair of guide plates 120, 121 and 123 may be smaller than the height of the nozzle body 110. In addition, Lt; RTI ID = 0.0 > height. ≪ / RTI >

At this time, the height of the guide plate 120 (121, 123) is preferably 22 mm or more. This is because if the height of each of the guide plates 120 (121, 123) is lower than this, the marble mixture overflows beyond the guide plate.

5 is a plan view of a nozzle for manufacturing artificial marble according to another embodiment of the present invention.

5, the artificial marble manufacturing nozzle 100 may include a pair of guide plates 120 and 121 and 123 formed in the nozzle body 110 in a direction in which the discharge port 130 is formed.

Unlike the embodiment of the present invention shown in FIG. 2 to FIG. 4, the pair of guide plates 120 and 121 shown in FIG. 5 gradually increase in distance from the nozzle body 110 Are arranged to be inclined so as to increase the spacing between them.

That is, the pair of guide plates 120 (121, 123) have a shape which is inclined at a predetermined angle (a). Therefore, W2, which is a distance on the end side, can be formed relatively larger than W1, which is a distance on the nozzle body 110 side.

According to this structure, it is possible to regularly and uniformly obtain the marble patterns which are different from the above-described one embodiment of the present invention. In addition, the guide plates 120, 121, Can be made adjustable.

Further, in the case of the artificial marble manufacturing nozzle 100 according to the embodiments of the present invention, a pair of guide plates 120 (121, 123) are detachably and detachably coupled from the nozzle body 110 . As a result, when the guide plate is damaged or damaged, it can be easily replaced with a new one, thereby eliminating the inconvenience of replacing the entire nozzle.

The artificial marble manufacturing nozzle 100 is preferably made of stainless steel, but is not limited thereto and may be made of other materials.

6 is a conceptual view briefly showing an artificial marble manufacturing apparatus 200 including a nozzle for manufacturing artificial marble according to the embodiments of the present invention.

According to the artificial marble manufacturing apparatus 200 configured as described above, a pair of guide plates 120 are provided in the direction of the discharge port of the nozzle body 110.

When a marble mixture C2 supplied from the marble mixture storage tank 30 is discharged toward the base mixture C1 through the nozzle body 110, a certain amount of the marble mixture C2 is introduced into the space between the pair of guide plates 120 A marble mixture of a plurality of marbles may be collected, and a kind of buffer space may be provided.

As a result, even when the viscosity or the discharge pressure of the marble mixture supplied through the nozzle body 110 from the marble mixture storage tank 30 is changed, a certain amount of the gap between the pair of guide plates 120 (121, 123) Marble mixture accumulates. Therefore, the discharge amount of the marble mixture C2 to the base mixture C1 can be actually kept constant. And the artificial marble thus produced can be realized with the feeling of natural marble.

As described above, according to the structure and function of the present invention, it is easy to apply to the artificial marble production process through the shape and structural improvement of the nozzle, and the artificial marble having the regular marble line width by discharging the marble compound at a constant line width Can be manufactured.

In addition, even when pressure or viscosity changes due to seasonal differences, the line width and shape of the marble compound are uniformly discharged, so that a regular, regular and clear pattern of marbles can be formed.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the scope of the invention is not limited to the disclosed exemplary embodiments. It is obvious that a transformation can be made. Although the embodiments of the present invention have been described in detail above, the effects of the present invention are not explicitly described and described, but it is needless to say that the effects that can be predicted by the configurations should also be recognized.
