The present invention relates to an alignment jig for ion beam uniform irradiation and a method for modifying a juicer gear surface using the same.

Recently, many studies have been conducted on the nutritional components, anti-cancer, antioxidant, and antimutagenic effects of green juice. The effects of green juice include anti-cancer and mutagenic effects, cholesterol removal, blood lipid reduction, arteriosclerosis, blood pressure increase, platelet aggregation, prevention of tooth decay, antioxidant, aging, heavy metal removal, blood sugar reduction, fatty liver Prevention, anti-allergy, tobacco and alcohol detoxification, skin care, immune enhancement, constipation improvement, diuretic effect, stress relief, memory and judgment enhancement and alkaline constitution improvement effect. Green juice also restores mental and physical fatigue and strengthens and normalizes the function of all organs so that they are always healthy. In addition, it boosts stamina, reduces sleep time, and supplies various vitamins and minerals, which is good for brain development. It is also good for chronic diseases and adult diseases by releasing toxins in the body caused by blood turbidity. Steady green juice can be treated for chronic diseases such as liver disease or diabetes. In particular, green juice contains more than three times more calcium and iron than milk. Green juice is also effective for growing children and those who are suffering from mental labor. Therefore, many people are drinking green juice, and the demand for green juice is increasing.

Regarding the technology related to the conventional juicer, in the Republic of Korea Patent Publication No. 194-0023401, a conveying part for transferring the material to the cutting step by a screw having a large pitch, and a cutting part for easily squeezing juice by receiving the material from the conveying part finely and , A juice part which is supplied with finely pulverized material from the cut part and squeezes juice while gradually compressing the screw with a small pitch, and a discharge part which discharges the debris (fiber) which has been juiced from the juice part. The present invention discloses a juicer which is provided with a conveying part, a cutting part, a juice part and a carrying out part on the same axis so as to continuously juice a large amount of material at one time.

In Korean Patent Publication No. 194-0020967, a drive gear of a pair of cutting gears connected to a main body driving unit is configured to be smaller than a driven gear, a driven gear and a driving gear are inclined, and an ogre is installed on the front of the cutting gear. The mesh covering the main surface of the cutting gear and the ogre is installed to be separated into two stages, and the cover covering the driving part pivots pivotally about the axis, and starts the juicer which can be screwed to the front. have.

In addition, the Republic of Korea Patent Registration No. 146323 is installed in the main body with a drive motor, detachable to the main body and the transfer casing is formed in the material inlet, the liquid discharge port and the waste outlet, built in the transfer casing and transfer the rotational force of the drive motor A pair of helical gears that receive and interengage each other and chop the input material, the opening and closing means for selectively opening and closing the material inlet, rotatably installed inside the opening and closing means, and installed in the material inlet. The present invention discloses a juicer capable of improving the safety of the juicer and shortening the juice administration time by including a compression means for compressing the gas under rotation.

However, the initial juicer gear was composed only of metal parts, and the metal gears were in contact with each other, so that the degree of inflow of the metal powder into the juice of juice was serious.

To compensate for this, a juicer gear composed of plastic and metal parts was designed, which is in contact with the plastic gears, but is not designed to be spaced between the metal gears. As a result, the inflow of metal powder was reduced, but in order to extract juice, a large pressure must be applied to the vegetables to be juiced. In this process, metallic elements were removed from the surface of the gear by friction between the vegetables and the gears. In recent years, the results of the analysis showed that the inflow into the juice exceeds 0.05 ppm, the WHO standard.

As a method of preventing such closed end, there is a use of a harder material, but the harder the material, the higher the cost of the material, as well as the processability of the juicer gear, the lower the manufacturing cost. Therefore, it is necessary to develop a method of suppressing the dropping of metal powder by friction by modifying the surface to stainless steel or similar metal material having good workability and corrosion resistance.

Techniques attempted to modify the juicer gear surface include coating a harder material onto the juicer gear surface. In this case, however, there is a problem in that the coating material peeled off by the peeling of the coating layer can be drunk together with the green juice.

As another method of modifying the surface of a material, a method of implanting ions into the surface of a material using an ion implanter is known.

The effects occurring on the material during ion implantation can be explained by dividing into a near surface effect and an inner surface effect. First, the near-surface effects of materials due to ion implantation include: 1) heating, 2) desorption of physically or chemically attached foreign matter, and 3) increased mobility of other atoms attached to the surface ( enhancement of mobility, 4) surface adhesion of colliding ions, 5) emission of secondary electrons, 6) reflection of colliding particles such as ions or neutral atoms, 7) sputtering or sputtering of atoms or particle clusters on the surface Resorption of atoms.

Next, the sub-surface effects include: 1) heating, 2) increasing the number of escapes and lattice defects of the chain collision process, 3) implantation of collision ions, and 4) internal implantation of surface elements. And 5) trapping of mobile species at lattice defects.

These microphysical and chemical changes are associated with changes in the macroscopic properties of the material. That is, when ions are injected into the polymer material, first, the optical properties are changed, second, the electrical conductivity is improved, and third, the surface hardness is improved. In the case of metal materials, mechanical properties such as hardness, bending strength, fracture toughness, fatigue resistance, friction resistance, etc. are increased, and chemical resistance is reported to be improved.

Mechanisms for improving mechanical properties include first, the formation of compressive residual stress due to the increase of the volume of the surface, and second, the potential due to the formation of solid hardening effect, strain hardening effect, formation of fine deposits (nitride, carbide, compound alloy, etc.) Mechanisms are known, such as slowing the movement of dislocations and, thirdly, preventing microwelding due to a decrease in reactivity with other materials when less reactive nitrides or carbides are formed on the surface.

In addition, mechanisms for improving chemical reactivity are known to adsorb foreign substances and suppress out-diffusion of base metal alloy elements due to the formation of nitrides having less reactive surface.

However, there have been no reported examples of attempts to apply the ion implantation technique to the juicer which has such characteristics.

Therefore, the ion implantation technique was applied as a method of modifying the surface of the juicer gear to prevent the metal element from falling off from the surface of the juicer gear. However, the conventional ion implantation method is not easy to uniformly irradiate the ion beam on the surface of the gear material, there is a problem that can not effectively perform surface modification.

Accordingly, the present inventors devised an alignment beam for uniformly irradiating ion beams that can irradiate ion beams uniformly, and developed a method for modifying the juicer gear surface using the same, and completed the present invention.

An object of the present invention is to provide an alignment beam for ion beam uniform irradiation that can modify the surface of the juicer gear by injecting ions evenly on the gear surface.

Another object of the present invention is to provide a method for modifying the juicer gear surface by developing an optimal ion implantation process that can prevent the removal of metal elements from the juicer gear surface.

In order to achieve the above object, the present invention is formed in a circular plate made of a metal material, the beam hole is formed so as to vertically penetrate in the center, an ion implantation pointer is attached on one side concentric circles of the beam hole, the ion implantation A clamping hole is formed in the concentric inner circumferential surface corresponding to the pointer, and provides a sorting jig for ion beam uniform irradiation configured to rotate and revolve a plurality of gears screwed to the clamping hole.

The present invention also provides a method for modifying a juicer gear surface that suppresses the dropping of metal elements from the juicer gear surface by ion implantation using the alignment jig for uniform ion beam irradiation.

Hereinafter, the present invention will be described in detail.

Specifically, the present invention provides an alignment jig capable of irradiating an ion beam uniformly.

The alignment jig 10 for uniform irradiation of the ion beam according to the present invention is a circular flat plate 20 made of a metal material, and forms a beam hole 30 so as to vertically penetrate at the center thereof, and an ion implantation pointer is formed on one side concentric circle of the beam hole. 40 is attached to the inner circumferential surface of the concentric circle corresponding to the ion implantation pointer, a clamping hole 50 is formed, and a plurality of helical type gears 60 coupled by screws provided to rotate and revolve in the clamping hole 50. It is configured to include).

The jig 10 which concerns on this invention is a shape which consists of a circular flat plate 20, and is comprised as a metal material. In the circular flat plate, the beam hole 30 is formed by allowing the center to penetrate as a predetermined diameter in the vertical direction. The ion implantation pointer 40 is firmly attached to one side of the beam hole 30.

The beam hole 30 is positioned in the vertical direction in the direction in which the ion beam is irradiated.

The clamping hole 50 is formed on the inner circumferential surface of the concentric circle corresponding to the ion implantation pointer 40. The clamping hole 50 is equipped with a plurality of helical type gears 60 coupled with screws provided to rotate and revolve, and if necessary, the number can be elastically designed. Preferably it may be designed to be at least 20 or more for uniform ion implantation and mass production.

The alignment jig for ion beam uniform irradiation is equipped with a plurality of helical type gears 60 at a time so that the entire mounting plate rotates as each gear rotates. In this case, the gear 60 may rotate and revolve, and the rotation and revolving speed of the gear 60 may be designed to rotate at a constant speed so that the ion beam is uniformly irradiated onto the surface of the gear.

The present invention also provides a method for modifying a juicer gear surface that suppresses the dropping of metal elements from the juicer gear surface by ion implantation using the alignment jig for uniform ion beam irradiation.

The 'green juicer gear' referred to in the present specification includes all commonly used juicer gears, and the material may also use commonly used plastic, stainless steel, or similar metal material, and preferably stainless steel. However, the present invention is not limited thereto. The stainless steel is added to the iron (Fe) more than 12% chromium (Cr), optionally containing a small amount of carbon (C), nickel (Ni), silicon (Si), manganese (Mn) and molybdenum (Mo) Corrosion resistance, heat resistance, surface properties, etc. are excellent characteristics, and may be variously classified according to chemical components and metal structures, and include, for example, SUS303. It is used suitably also for the material of the juicer gear to be used by this invention, In the present invention, a kind is not limited.

'Ion implantation' referred to in the present invention means that high energy ionized elements collide with the target material surface and invade ions into the material, but sputtering effect of releasing atoms or molecules on the target surface in vapor phase Entails. Variables of this process include variables such as target material, incident energy, and ion amount, and the present invention suggests optimal conditions.

The ions mentioned in the present invention include nitrogen (N), carbon (C), boron (B), and the like, which are commonly used, and may be used alone or in combination. Nitrogen was used because formation is important.

Specifically, in the present invention, in order to modify the surface of the juicer gear, it is preferable to irradiate a nitrogen ion beam in the energy range of 50 to 300 keV.

The energy injected is related to the surface characteristics of the ionizing treated green juicer gear. In general, the higher the energy of implanted ions and the greater the amount of implanted ions, the more the surface modification proceeds and the more the hardness increases, which prevents the dropping of metallic elements. However, when too much, an adverse effect of irradiation damage may occur. As it is elevated, it should be adjusted to conditions that exhibit desirable physical properties and cost appropriately.

In the present invention, as the juicer gear is implanted with ions having the energy in the above range, nitride having a high hardness is formed on the surface without a separate heat treatment, and the durability of the juicer gear can be improved, and dropping of metal elements can be suppressed. Can be. In this case, it is appropriate to implant ions at 5 × 10 ¹⁶ to 5 × 10 ¹⁷ ions / cm ² .

At this time, the rotational speed of the jig rotation and revolution is preferably selected within the range of 1 to 10 rpm. Exceeding the above range may cause problems in the degree of vacuum in the ion beam irradiation chamber, which may be undesirable.

Therefore, uniformly injecting ions into the juicer gear using an ion implanter equipped with an ion beam uniform irradiation alignment jig according to the present invention greatly improves the removal of metal elements from the juice gear even if the juicer gear is modified and subjected to strong pressure during the juice process. By suppressing, the content of impurities in the green juice can be greatly reduced.

Alignment jig for ion beam uniform irradiation according to the present invention can be easily applied not only for the juicer, but also for modifying the surface of the metal gear or the plastic gear.

Hereinafter, the present invention will be described in detail with reference to Examples.

However, the following examples are illustrative of the present invention, and the content of the present invention is not limited by the examples.

< Example  1>

Using a ion injector (Atomic Energy Research Institute) in an ion beam uniform irradiation alignment jig according to the present invention, while rotating the juicer gear made of SUS303, the surface of which is stainless steel, 70 keV of nitrogen ions with a strength of 1 × 10 ¹⁷ ions / ㎠ Injected into.

< Experimental Example  1> Surface hardness change when nitrogen ion is injected into the juicer gear surface

In order to determine how the ion implantation affects the gear surface hardness, the hardness of the juicer gear surface obtained in Example 1 was measured using a micro hardness meter.

The measurement results are shown in Fig.

As shown in FIG . 3 , it was confirmed that the hardness of the surface was increased by about two times or more than before the ion implantation.

< Experimental Example  2> When nitrogen ion is injected into the plastic part material of the juicer gear Surface hardness change

In order to examine the effect of ion implantation on the hardness of plastics, 70 keV of nitrogen ions were implanted into polyacetal parts of the juicer gear parts with ion amounts of 5 × 10 ¹⁶ / ㎠ or 1 × 10 ¹⁷ / ㎠ . Then the hardness of the surface of the part was measured using a micro hardness tester.

The measurement results are shown in Fig.

As shown in FIG . 4 , it can be seen that the ion implantation improves the hardness even in the plastic material by confirming that the hardness of the surface is increased by about 7 times or more than before the ion implantation.

< Experimental Example  3> After juice injecting nitrogen ion into the juicer gear surface Pine needle  Impurity Analysis.

In Example 1, when the pine needle was juiced using a gear in which nitrogen ions were injected and a gear in which ion was not implanted, the dropout rate of the metal element dropped from the gear surface was measured. At this time, the ion implantation energy was divided into 60 keV, when the ion amount was used 5 × 10 ¹⁶ / ㎠ and 70 keV, when the ion amount was 1 × 10 ¹⁷ / ㎠, nitrogen ions were injected. The content of chromium and nickel was analyzed by analysis.

The analysis results are shown in Table 1.

Analysis element Ion implantation conditions Elemental amount (mg / l) Ion Type Energy (keV) Ion amount (ion / cm ² ) Before ion implantation After ion implantation  chrome N 60 5 × 10 ¹⁶ 0.22 0.07  nickel N 60 5 × 10 ¹⁶ 0.48 0.27  chrome N 70 1 × 10 ¹⁷ 0.22 0.04  nickel N 70 1 × 10 ¹⁷ 0.48 0.09

As shown in Table 1 above, when nitrogen ions were injected into the gear surface at a strength of 60 keV and an ion amount of 5 x 10 ¹⁶ / cm 2, the chromium content of the gear constituents in the pine needle extract was used to prevent ion implantation. When using the ion implanted gear at 0.22 mg / ℓ was reduced to 0.07 mg / ℓ, nickel content was confirmed to be inhibited by reducing from 0.48 mg / ℓ to 0.27 mg / ℓ. Even when nitrogen ions were injected into the gear surface with a strength of 70 keV and ion amount of 1 × 10 ¹⁷ / ㎠, the chromium content was used at 0.22 mg / l when the gear was not implanted. When it was reduced to 0.07 mg / ℓ, the nickel content was reduced from 0.48 mg / ℓ to 0.27 mg / ℓ confirmed that the dropping of the metal element is inhibited. Therefore, when ions are injected into the juicer gear, the surface of the gear is modified to improve the gear hardness, so that the metal element can be prevented from falling off from the gear surface during the juice.

As described above, by uniformly injecting ions into the juicer gear using the ion beam uniform irradiation alignment jig according to the present invention, the surface of the juicer gear is modified and strengthened so that metal elements such as chromium and nickel are dropped during the juice process. By greatly suppressing the content of impurities in the green juice can be greatly reduced.
