According to one embodiment, the screw portion 122 may include a first screw portion 122a and a second screw portion 122b. In detail, the screw portion 122 may include at least one of a first screw portion 122a and a second screw portion 122b which are rotated in opposite directions. When a plurality of the first screw portion 122a and the second screw portion 122b are provided, the first screw portion 122a and the second screw portion 122b may be sequentially arranged alternately from the upper side to the lower side have.

A sawtooth gear is formed. The gear formed on one end face of the first center shaft 123a and the gear formed on the other end face of the second center shaft 123b are connected via the bevel gear 125.

The raw material m from which the gas is removed through the gas removing unit 140 moves to the impurity separating unit 150 to separate the metallic impurities P contained in the raw material m. Hereinafter, the impurity separator 150 will be described in detail with reference to FIGS. 6 and 7. FIG.

6 and 7 are views showing the impurity separating unit 150 of the hose producing unit 100 according to the embodiment of the present invention.

The impurity separating section 150 can prevent impurities P from being contained in the manufacturing process of the hose H by separating the metal impurities P contained in the raw material m, (H) can be produced. More specifically, the impurity separator 150 can prevent the hose H from being roughened by the metal impurities P contained in the raw material m by removing the metal impurity P from the raw material m, It is possible to prevent the interior of the hose from rusting during repeated use of the hose and to prevent the hose from being torn or cracked by the metal impurities P due to the use environment of the hose used to bend or warp The completeness of the hose H to be extruded can be enhanced. The impurity separator 150 is configured to remove the metallic impurities P contained in the raw material m or the metallic impurities P generated during the movement of the raw material m. The impurity separating unit 150 is connected to the gas removing unit 140 and may include a conduction tube 151 and a coil part 152.

The conduction tube portion 151 is formed of a conductive material in a tubular shape inside the second raw material moving portion 143 and the coil portion 152 is wound in a coil shape solenoid wound around the outer peripheral surface of the second raw material moving portion 143 ≪ / RTI > In detail, the coil part 152 may be a helical solenoid. More specifically, the coil portion 152 may be a solenoid in which the helical coil is provided in a cylindrical shape. The diameter of the spiral coil of the coil part 152 may be larger than the diameter of the conduit tube 151 and may be positioned to surround the conduit tube section 151. The conduit tube section 151 may be positioned on the second material transfer section 143 However, if the second material moving unit 143 is a conductive material, it may not be separately provided.

The coil portion 152 has polarities of the cathode and the anode at one end and the other end, and the current I can flow in one direction by applying the current I. When the current I is applied and the current I flows along the coil portion 152, a magnetic field is formed around the conductor of the coil portion 152 according to the electromagnetic induction law of Faraday (1791 to 1867). In detail, when the current I flows, the helical coil portion 152, which is closely and tightly and spirally extended in a cylindrical shape, has a magnetic field outside the coil portion 152 and a magnetic field of a relatively uniform size . The current I flows through the conduction tube section 151 located in the inner side of the coil section 152 based on the above described technique and the conduction tube section 151 has a magnetic force through the induced current I. Therefore, when the current I is applied to the coil part 152, the conductive pipe part 151 is changed in its electromagnet properties and the conductive material part 151 having a magnetic force causes the raw material in the second raw material moving part 143 m are separated by the magnetic force in the outward direction in which the conduction tube portion 151 is located. More specifically, the impurity P contained in the raw material m is mostly melted and removed due to the heating temperature of the raw material m, and the impurity P contained in the raw material m has a high melting point It may remain in the raw material m in some cases. However, when the heating temperature is increased to raise the heating temperature, the chemical property of the raw material m may be changed or bubbles may be generated due to boiling, so that the raw material m in which the conductive pipe portion 151 is not melted The metal impurity P is moved in the outward direction of the substrate W. Here, it is preferable that the melting point of the raw material (m) has a melting point lower than the melting point of the metallic impurity (P) so that the metallic impurity (P) maintains a solid state. The metal impurities P already dissolved in the process of separating the metal impurities P may be separated from each other in the outer direction of the material m in which the conduction pipe portions 151 are located. Meanwhile, in the case of the rotating shaft 50 positioned in the impurity separating portion 150, it is preferable that the rotating shaft 50 is made of a non-metallic material so that no magnetic force is applied by the coil portion 152.

The metal impurities P are moved in the outer direction of the hose H to be cooled through the cooling unit 160 and the metal impurities P are separated in the inner direction of the hose H, Only the high raw material m is located. That is, the inner side of the hose H has a relatively durable and smooth surface, and it is possible to prevent scale from being generated. Even if water is flowed into the completed hose H, , Maintenance and management are easy. The hose H of high purity can be manufactured by removing the metal impurity (P) layer where the metal impurity (P) is located in the outer direction of the raw material (m) through the grinding portion (180) described later.

The cooling unit 160 located at the lower end of the impurity separating unit 150 shown in FIGS. 7 and 8 has a structure in which the raw material m from which gas and metal impurities have been removed is cooled in a hose form. It is preferable that the cooling unit 160 should provide a lower temperature than the melting point of the raw material m and perform rapid cooling so that the metal impurities P separated at a lower temperature are not mixed again. The cooling method of the cooling unit 160 may be cooled by lowering the external temperature, or it may be cooled by spraying liquefied nitrogen.

The hose H cooled by the cooling unit 160 is extruded out of the raw material moving unit through the extrusion unit 170.

Hereinafter, the grinding unit 180 will be described in detail with reference to FIG.

8 is a view showing a grinding unit 180 of the hose manufacturing unit 100 according to an embodiment of the present invention.

The grinding portion 180 is provided in a tubular shape that rotates in one direction and may include one or more grinding blades 181 therein. The inner diameter of the grinding portion 180 may be equal to or greater than the outer diameter of the hose H to be extruded and has a diameter equal to the outer diameter of the extruded hose H, In addition, the grinding blade 181 may be provided in plurality to remove the metal impurity (P) layer more quickly. The metal impurity (P) layer formed on the outside of the hose H is ground and removed by the rotation of the grinding part 180 having the grinding blade 181 therein. Therefore, when passing through the grinding unit 180, a high-purity hose H can be completed.

Hereinafter, the knitting section 200, the polishing section 300, and the winding section 400 will be described with reference to FIG.

The knitting section 200 is configured to knit the metal yarn 211 on the outer circumferential surface of the hose H manufactured by the hose producing section 100, and a conventional well known knitting machine can be used. The hose H braided by the knitting portion 200 can be prevented from being damaged and increasing in strength. In addition, the metal yarn 211 may be formed of a metal yarn 211 of a shape memory alloy material. As the shape memory alloy metal sheet 211, various shape memory alloy materials such as known Nitinol (nickel-titanium), copper-zinc-aluminum alloy, etc. may be used.

The grinding unit 300 grinds the hose H braided by the knitting unit 200 and grinds the outer side of the metal yarn 211 braided around the outer circumference of the hose H, ) Can be made smooth. The polishing unit 300 may polish the outside of the metal yarn 211 through various methods such as chemical or physical methods. When the grinding unit 300 is provided, it is possible to provide a braiding hose H of higher quality and higher quality.

The winding section 400 is configured to be wound around a bobbin 410 such as a finished braiding hose H and stored. The winding unit 400 may be a winding unit 400 having a bobbin 410 that is well known in the art. However, in the case where the metal yarn 211 braided around the outer circumferential surface of the braid hose H is a shape memory alloy, the metal yarn 211 is shape-memorized in a state where the braid hose H is wound around the bobbin 410 The heat treatment 420 may be performed at a predetermined temperature. This is because, when the hose is rewound to adjust the shape of the hose freely at room temperature, the water is supplied to the outer metal yarn 211 of the hose at a predetermined temperature or more to easily return to the originally stored wound state In order to make it possible. Here, the temperature at which the metal sheet 211, which is the shape memory alloy, returns to the shape memorized in accordance with the transformation temperature at which shape memory is performed is determined. In general, the transformation temperature is preferably a temperature much higher than the temperature at which the shape memory alloy returns to the stored shape.

Hereinafter, a method of manufacturing the braiding hose H of the present invention will be described with reference to Figs. 10 and 11. Fig.

Referring to FIG. 10, the method for fabricating a braiding hose according to the present invention may further include a hose manufacturing step (S100), a braiding step (S200), a winding step (S400), and a polishing step (S300).

The raw material supply step (S110) is a step of supplying at least one raw material (m) for producing the hose (H). Here, the raw material (m) is preferably supplied with a raw material (m) for producing natural rubber or synthetic rubber. The supplied raw material (m) may be a primary raw material (m) containing impurities (P) that have not undergone processing and may be supplied with the processed raw material (m).

The raw material mixing step (S120) is a step of mixing the supplied raw materials (m). More specifically, in the raw material mixing step (S120), the supplied raw materials (m) can be evenly mixed by the plurality of first screw portions (122a) and the second screw portions (122b) rotating in different directions.

The heating step (S130) is a step of heating and melting or melting the mixed raw material (m).

The gas discharge step S140 controls the acidity of the raw material m by separating the gas generated by heating the raw material m in the liquid state This is a step for preventing the generation of bubbles. In the gas discharging step S140, a method of discharging gas through a separate gas removing unit 140 may be used.

The impurity separation step S150 separates the metal impurity P contained in the raw material m from which the gas is removed through the gas discharging step S140. It is possible to prevent impurities P from being contained during the production of the hose H through the impurity separation step S150 and thus to produce a hose H of good quality with a high degree of completion. More specifically, the impurity separator 150 can prevent the hose H from being roughened by the metal impurities P contained in the raw material m by removing the metal impurity P from the raw material m, It is possible to prevent the interior of the hose from rusting during repeated use of the hose and to prevent the hose from being torn or cracked by the metal impurities P due to the use environment of the hose used to bend or warp The completeness of the hose H to be extruded can be enhanced. In the impurity separation step S150, a magnetic force is generated in the conductive pipe portion 151 of the conductive material by the induced current I generated by applying a current to the coil portion 152 composed of the solenoid, ) Can be used.

The cooling step S160 is a step of cooling the raw material m in which the metal impurity P has been separated to the outside of the hose H in this state.

Thereafter, the cooled hose H is extruded through the extrusion step S170.

The grinding step S180 is a step of grinding the separated metal impurity (P) layer outside the extruded hose H by using the grinding blade 181. [ More specifically, the grinding step S180 includes separating the impurities P by a tubular grinding unit 180 rotating in one direction and one or more grinding blades 181 provided on the inner circumferential surface of the grinding unit 180 Thereby grinding and removing the metal impurity (P) layer outside the cooled hose (H). The hose H of high purity can be completed through the grinding step S180.

Thereafter, the metal yarn 211 can be braided on the outer peripheral surface of the hose H through the braiding step S200. Here, the metal yarn 211 may be a commonly known braided metal yarn 211 or may be a metal yarn 211 of a shape memory alloy. The braided hose H completed through the braiding step S200 may be wound immediately, but it is possible to provide the braiding hose H having a higher degree of completion through the polishing step S300.

The winding step S400 is a step of winding the finished braiding hose H onto the bobbin 410. When the braided metal yarn 211 is knitted in the braiding step S200, (S450) of causing the shape memory to be wound in a state wound on the winding shaft (211).
