FIGS. 2B and 2C are perspective views for explaining the configuration of the modified 3D fiber matrix in the continuous thermal insulation system according to the embodiment of the present invention. FIG.

As shown in the drawing, the continuous thermal insulation system according to the embodiment of the present invention includes a dispenser 110a, a mixer 120, a hopper 130, a 3D fiber matrix A1, a lapping roller 140, And a completely new type of 3D fiber matrix A1 which is composed of compression rollers 150a and 150b150c and can be formed into a heat insulating panel AB3 together with the powder material while safely wrapping the powder material so as not to be scattered, It is possible to manufacture a heat insulating material with little use. In particular, the introduction of such a 3D fiber matrix (A1) enables the use of the powder material directly to produce an insulation material, thereby saving a considerable amount of time required for melting and mixing the binder so that the continuous production of the insulation material using the rollers It can be smoothly performed.

Hereinafter, a detailed description will be made of a continuous thermal insulation system according to an embodiment of the present invention.

When the mixer 120 is supplied with various powder materials from the dispenser 110a, the powder materials are uniformly mixed to form the composite powder material B1.

The hopper 130 receives the composite powder material B1 mixed in the mixer 120 and discharges the mixed powder material B1 downward. The composite powder material B1 discharged from the hopper 130 is accommodated by the 3D fiber matrix A1 located thereunder.

The 3D fiber matrix A1 plays a pivotal role in forming the composite powder material B1 without a binder in the embodiment of the present invention. As shown in FIG. 2A, the 3D fiber matrix A1 includes a plurality of receiving holes Aa, The hopper 130 has a structure in which the hopper 130 is patterned in a transverse direction and a longitudinal direction, and the composite powder material B1 discharged from the hopper 130 can be received in the plurality of receiving holes Aa.

As shown in FIG. 10A, the 3D fiber matrix A1 may have a hole shape in which both the upper and lower holes are opened while the receiving holes Aa form a regular pattern in the horizontal direction and the vertical direction, Only the cup shape can be opened.

Meanwhile, the 3D fiber matrix A1 may have a water-repellent structure, which is a 3D structure having an irregular shape in the size and arrangement of the receiving hole Aa as shown in FIG. 10C.

The most important point is that the receiving holes Aa are opened so as to receive the composite powder material B1 discharged from the hopper 130 and are sufficiently large enough to accommodate the composite powder material B1 . Such a 3D fiber matrix A1 is positioned below the hopper 130 after being conveyed along the conveyor 190 from the feeding device 110b such as the winding roller.

The 3D fiber matrix A1 is made of a pressure plastic material which is stretched when pressed by the lapping roller 140 to maintain its stretched state. Particularly, some of the pressure plastic materials corresponding to the 3D fiber matrix (A1) according to the embodiment of the present invention are synthetic fiber materials such as PET fiber, PP fiber and glass fiber, natural fibers such as cotton, wool, There is material. They are provided so as to have appropriate strength and elongation to such an extent that the 3D fiber matrix material is not broken during the heat-seal molding. When the 3D fiber matrix A1 is made of a material having appropriate strength and elongation such that the 3D fiber matrix A1 is not broken while being pressed, the 3D fiber matrix A1 is stretched corresponding to the composite powder material B1 spreading to the left and right when pressed by the wrapping roller 140 It is possible to protect the composite powder material B1 from leakage.

Here, as shown in FIG. 10A, the 3D fiber matrix A1 having the hole-shaped receiving hole Aa and the 3D fiber matrix A1 made of the wool-like structure having the irregular micro-receiving hole Aa as shown in FIG. The composite powder B1 is pressed in a state of being covered with the upper casing 181a and the lower casing 181b having a dense structure such as a nonwoven fabric as shown in FIG. In this case, a first outer sheath roller 180a for supplying the upper outer sheath 181a and a second outer sheath roller 180b for supplying the lower outer sheath 181b are additionally provided.

On the other hand, in the case of the 3D fiber matrix A1 having the cup-like receiving hole Aa as shown in FIG. 10B, in order to prevent the composite powder material B1 from escaping, only the upper envelope 181a is used to form the 3D fiber matrix A1 In a state in which it covers the upper part. In this case, if the cup-shaped receiving hole Aa is filled with only about 2/3 of the composite powder B1 without being completely filled with the composite powder B1, the upper envelope 181a is not required when the 3D fiber matrix A1 is squeezed The composite fiber material (B1) can be wrapped while covering the upper part of the 3D fiber matrix (A1).

In particular, in the case of the 3D fiber matrix A1 having the receiving hole Aa having the regular shape shown in FIGS. 10A and 10B, the through holes Ac are formed in the intermediate wall Ab formed between the receiving holes Aa As shown in FIG. As a result, when the 3D fiber matrix (A1) is pressed by the lapping roller (140), vertical collapse easily occurs and it can be naturally pressed together with the composite powder material (B1).

The lapping roller 140 presses the 3D fiber matrix A1 while the composite fiber material B1 is accommodated and laminates the composite fiber material B1 in a compressed form of the 3D fiber matrix A1 Thereby forming the pressure member AB2. 3, the lapping roller 140 is installed in such a manner that a pair of flat rollers face each other with a gap therebetween, and the composite powder material B1 And press-convey the received 3D fiber matrix A1.

4, the lapping roller 140 includes a cylindrical roller body 141 and an arc-shaped pressing protrusion 143 formed continuously on the outer circumferential surface of the roller body 141 in a circumferential direction, 142). ≪ / RTI > It is preferable that the pressing protrusion 142 is about four to seven along the circumferential direction of the roller body 141 and the curvature thereof is only gently formed to a degree slightly larger than that of the roller body 141. According to the modified configuration of the lapping roller 140, it is possible to secure a free space or buffer space through which the composite powder material B1 can flow by the recess formed between the pressing protrusion 142 and the pressing protrusion 142 It is possible to effectively suppress the problem that the composite powder material B1 is pushed in the lateral direction of the lapping roller 140 due to the pressurization of the lapping roller 140 and may deviate from the 3D fiber matrix A1.

5, a pair of the lapping rollers 140 are arranged in a spaced relation to each other in a pair with the conveyor 190, as shown in FIG. 5, instead of the pair of lapping rollers 140 facing each other It is possible. According to such a configuration, since the pair of lapping rollers 140 pressurize, only one of them pressurizes, so that the instability due to the eccentric load can be raised. However, it is advantageous that the system can be formed with a simpler configuration by controlling only this problem. The modified lapping roller 140 may be configured to have either the pressing protrusion 142 as shown in FIG. 5 or a flat roller without the pressing protrusion 142.

The pressing rollers 150a and 150b150c further press the pressing member AB2 formed from the circular member AB1 by the lapping roller 140 to form a thinner heat insulating panel AB3 . 6 and 7, a plurality of the pressing rollers 150a and 150b150c are arranged in a row so that the thickness of the pressing material AB2 formed on the lapping roller 140 is gradually reduced . What is important here is to gradually narrow the separation distance between the pressing rollers 150a and 150b150c facing each other. This is because the pressing rollers 150a and 150b150c It is important to make it gradually natural.

When the pressure member AB2 passes through the compression rollers 150a and 150b150c, the pressure member AB2 has the shape of a heat insulating panel AB3 and is formed into a final product by the molding machine 160 as shown in FIG. However, it is needless to say that the molding machine 160 shown in FIG. 1 is shown in the form of a cutter for simple cutting, but it may be provided as an apparatus for finishing a more complex shaped product. Reference numeral 170, which is not described in the reference, is a loading box.

As described above, the continuous thermal insulation system according to the embodiment of the present invention can reduce the time required for melting and mixing the binder and can produce a large amount of thermal insulation material despite the use of the powder material.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It is clear that the present invention can be suitably modified and applied in the same manner. Therefore, the above description does not limit the scope of the present invention, which is defined by the limitations of the following claims.
