5 is a perspective view showing a specific configuration of the hydraulic jack, and FIG. 6 is a conceptual view for explaining an internal configuration and a working principle of the hydraulic jack.

As described above, according to another embodiment of the present invention, the size separator 30 can be installed on the body frame 10 via a hydraulic jack so that the inclination angle thereof can be adjusted.

Specifically, the hydraulic jack 1 according to the embodiment of the present invention includes a main body 100, an outer cylinder 200, a press lever 300, and a release valve 400.

The main body 100 is a cylindrical member, and a space in which a working fluid can be stored is formed, and the inner cylinder 110 and the lifting piston 120 can be disposed therein.

The inner cylinder 110 is a cylindrical member formed inside the main body 100, and a working fluid can be stored between the main body 100 and the inner cylinder 110.

The lifting piston 120 is a member installed in the inner cylinder 110 and reciprocating along the longitudinal direction of the inner cylinder 110. That is, when the working fluid is supplied to the inner cylinder 110, the size separator 30, which is in contact with the upper portion of the lifting piston 120 while the lifting piston 120 is lifted by the pressure of the working fluid, .

7 is a view showing an outer cylinder 200 constituting the hydraulic jack and a connecting portion 220 for engaging the pressure piston 210 and the pressure lever 300 of the outer cylinder 200. In the outer cylinder 200, The pressure piston 210 formed on the pressure lever 300 is physically coupled to the pressure lever 300 through the connection portion 220. Due to such a structural feature, the pressure piston 210 transmits the external force of the user provided through the pressure lever 300 Can receive.

The press lever 300 has a through hole for engaging a member such as a pipe or the like that can be held by the user. The user moves the pipe up and down in a state where the pipe is coupled to the push lever 300 An external force may be applied to the pressure lever 300. [ In another embodiment of the present invention, the pressure lever 300 may include the pipe described above or may be provided integrally with the pipe.

A specific operation principle of the hydraulic jack according to one embodiment of the present invention is as follows. When the user lifts the pressure lever 300, a negative pressure is formed on the outer cylinder 200 while the pressure piston 210 is lifted . Accordingly, the working fluid stored between the main body 100 and the inner cylinder 110 can flow into the outer cylinder 200 along the suction pipe 510.

Then, when the user presses the pressure lever 300, the pressure piston 210 descends and applies pressure to the working fluid sucked into the outer cylinder 200. Accordingly, the working fluid sucked into the outer cylinder 200 can move to the inner cylinder 110 along the supply pipe 520. At this time, a check valve is provided at one end of the suction pipe 510 connected to the outer cylinder 200, so that the working fluid can be fed only through the supply pipe 520. The lifting piston 120 is lifted by the pressure of the working fluid flowing into the inner cylinder 110. As the pressure of the inner cylinder 110 gradually increases, the lifting piston 120 gradually rises and the lifting piston (not shown) is lifted up gradually as the pressure of the inner cylinder 110 gradually increases. 120 to lift the size separator 30 in contact with the top.

The release valve 400 is formed at one end of the supply pipe 520 and is a valve-shaped member for releasing the pressure of the inner cylinder 110 according to a user's operation. That is, when the user desires to descend the size separator 30 to the original position, when the release valve 400 is opened, the high-pressure filled working fluid flowing into the inner cylinder 110 flows through the return pipe 530, The lift cylinder 120 is lowered by the gravity of the size separator 30 as the pressure of the inner cylinder 110 is lowered by the pressure of the lift piston 120 receiving gravity of the size separator 30, (30) can be lowered to the original position.

As described above, the hydraulic jack according to an embodiment of the present invention can raise or lower the heavy size separator 30 by using a small force repeatedly applied from the user to the lever 100. [

8 to 10 are perspective views illustrating a hydraulic jack according to another embodiment of the present invention.

FIG. 8 is a perspective view of a hydraulic jack according to another embodiment of the present invention, FIG. 9 is a view for comparing external cylinders constituting the hydraulic jack of FIG. 8, FIG. 10 is a view for explaining the internal construction and operation principle of the hydraulic jack shown in FIG. FIG.

Specifically, the hydraulic jack 1a according to another embodiment of the present invention includes a main body 100, external cylinders 200a, 200b, 200c, 200d, 200e, 200f, a press lever 300, .

The main body 100, the press lever 300 and the release valve 400 constituting the hydraulic jack 1a according to another embodiment of the present invention shown in FIG. The pressurizing lever 300 and the release valve 400 constituting the hydraulic jack 1 according to the embodiment are the same as those of the main body 100, the pressurizing lever 300 and the release valve 400. Therefore, repeated description will be omitted.

The hydraulic jack according to another embodiment of the present invention is characterized in that a plurality of outer cylinders 200 shown in FIG. 5 are provided. That is, in the hydraulic jack according to another embodiment of the present invention, a plurality of outer cylinders 200a, 200b, 200c, 200d, 200e, 200f, and 200g may be connected to the pressure lever 300. [ 8, a hydraulic jack according to another embodiment of the present invention includes six outer cylinders 200b, 200c, 200d, and 200e (hereinafter, referred to as " first cylinder ") 200 having a first outer cylinder 200a formed along a central axis coaxial with the pressure lever 300 , 200f, and 200g are arranged along the circumference of the first outer cylinder 200a. However, the present invention is not limited thereto, and the number of the outer cylinders is not limited to two or more.

Each of the outer cylinders 200a, 200b, 200c, 200d, 200e, 200f, and 200g is provided in a cylindrical shape, and a pressure piston is formed therein. That is, when the user applies an external force to the hydraulic jack by operating the pressure lever 300, the pressure lever 300 distributes the supplied external force to the respective external cylinders 200a, 200b, 200c, 200d, 200e, 200f, .

When the outer cylinders 200a, 200b, 200c, 200d, 200e, 200f, 200g are designed to have the same diameter, they are transmitted to the respective outer cylinders 200a, 200b, 200c, 200d, 200e, 200f, Can be uniformly dispersed. As another example, when the outer cylinders 200a, 200b, 200c, 200d, 200e, 200f, and 200g are designed to have different diameters, the external force can be distributed and transmitted in proportion to the size of the diameter.

The total sum of the diameters of all of the outer cylinders 200a, 200b, 200c, 200d, 200e, 200f, and 200g constituting the hydraulic jack may be designed to be smaller than the diameter of the inner cylinder 110. More specifically, The sum of diameters of the inner cylinders 200a, 200b, 200c, 200d, 200e, 200f, and 200g is designed to be less than 1/3 of the diameter of the inner cylinder 110. [ When the diameter of the outer cylinder is larger than the diameter of the inner cylinder 110, a force smaller than the magnitude of the external force applied to the outer cylinder can be transmitted to the inner cylinder 110.

A specific operation principle of the hydraulic jack according to another embodiment of the present invention will be described with reference to FIG.

In FIG. 10, the hydraulic jack according to another embodiment of the present invention is shown to include three outer cylinders 200a, 200b, and 200c. However, when two outer cylinders or four or more outer cylinders are provided, Principle may be the same or similar.

The pressure piston 210a, 210b, 210c of each of the outer cylinders 200a, 200b, 200c rises up when the user lifts the pressure lever 300 in a state where the hydraulic jack is in contact with the object at the lower part of the object to be raised. A negative pressure is formed in the outer cylinder 200. [ Accordingly, the working fluid stored between the main body 100 and the inner cylinder 110 can flow into the outer cylinders 200a, 200b, and 200c along the suction pipes 510a, 510b, and 510c.

Thereafter, when the user presses the pressure lever 300, the pressure pistons 210a, 210b, 210c descend while applying pressure to the working fluid sucked into the outer cylinders 200a, 200b, 200c. Accordingly, the working fluid sucked into the outer cylinders 200a, 200b and 200c can move to the inner cylinder 110 along the supply pipes 520a, 520b and 520c. The lifting piston 120 is lifted by the pressure of the working fluid flowing into the inner cylinder 110. As the pressure of the inner cylinder 110 gradually increases, the lifting piston 120 gradually rises and the lifting piston (not shown) is lifted up gradually as the pressure of the inner cylinder 110 gradually increases. 120 to lift the size separator 30 in contact with the top.

The hydraulic jack according to another embodiment of the present invention includes control valves for controlling the opening and closing of the shutoff valves 511a, 511b and 511c and the shutoff valves 511a, 511b and 511c installed at one end of the suction pipes 510a, 510b and 510c (Not shown).

Control means (not shown) may be provided in the form of a control circuit disposed inside the fastening bracket 150, and may be electrically connected to the shutoff valves 511a, 511b, and 511c. In this case, the control means (not shown) can open / close the respective shutoff valves 511a, 511b and 511c according to the user's operation.

The upward force applied to the lifting piston 120 is a pressing force against the diameter D of the lifting piston 120 and the lifting force W acting on the lifting piston 120 is expressed by the following equation (1) The sum of the diameters d of the pistons 210a, 210b and 210c and the external force w applied to the pressure pistons 210a, 210b and 210c.

That is, when the user transmits an external force w of a predetermined magnitude to the hydraulic jack 3 through the pressure lever 300, the lifting force of the lifting piston 120 is transmitted to the pressure piston (not shown) with respect to the diameter D of the lifting piston 120 210d, 210a, 210b, 210c. The diameter D of the lifting piston 120 is determined according to the diameter of the inner cylinder 110 and the sum d of diameters of the pressure pistons 210a, 210b and 210c is equal to the sum of the diameters D of the outer cylinders 200a, 200b and 200c The lifting force W acting on the lifting piston 120 is determined by the ratio of the diameters of the outer cylinders 200a, 200b and 200c to the diameter of the inner cylinder 110 Can be varied.

Therefore, the hydraulic jack according to another embodiment of the present invention can selectively open and close the shutoff valves 511a, 511b, and 511c by control means (not shown) The amount of fluid can be adjusted and the pressure of the working fluid can be controlled only through the pressure pistons 210a, 210b and 210c with the shut-off valves 511a, 511b and 511c being opened to control the lifting force of the lifting piston 120 do.

For example, when only the first shut-off valve 511a is closed in accordance with the user's control means (not shown), the external force applied to the working fluid acts when all the shut-off valve valves 511a, 511b and 511c are opened Only two-thirds of the external force w applied to the fluid can be delivered. In other words, according to the control of the control means (not shown), the diameter of the outer cylinders 200a, 200b and 200c can be varied to control the lifting force W of the lifting piston 120, The lifting height of the hydraulic jack 3 according to one operation of the pressure lever 300 can be adjusted according to the type of object to be lifted or the type of work to be performed after the object is lifted.

In some other embodiments, the control means (not shown) may automatically determine the shut-off valve valves 511a, 511b, 511c to be opened or closed.

For example, the control means (not shown) opens only one shut-off valve valve 511a, 511b, 511c until the pressure lever 300 is operated a predetermined number of times from the initial operation time of the hydraulic jack, 300) is operated more than the predetermined number of times, the plurality of shutoff valve valves 511a, 511b, 511c can be controlled to be opened. More specifically, the control means (not shown) allows only the first shut-off valve 511a to be opened until the first time the push lever 300 is operated, and until the push lever 300 is operated 6 to 10 times The first shutoff valve 511a and the second shutoff valve 511b are opened and all the shutoff valves 511a, 511b and 511c are opened from 11 times or more. In general, when a hydraulic jack is used to lift an object, there are not many kinds of operations that can not be performed at a low height. Therefore, if the object is raised at a high speed in the early stage and then raised to a proper height, It needs to be adjusted. At this time, according to the above-described features of the present invention, when only one shut-off valve is opened, the object is raised at a high speed in a comparatively short time, and then gradually increases as the number of shut- The rising speed can be reduced. Accordingly, the user has the effect of varying the elevation height of the object even if the hydraulic jack is always operated with a constant force.

As another example, the control means (not shown) can automatically determine the shutoff valve valves 511a, 511b, and 511c to be opened or closed according to the weight of the object disposed on the upper portion of the hydraulic jack.

To this end, the hydraulic jack according to still another embodiment may further include a weight sensing means (not shown).

The weight sensing means (not shown) senses the weight of the object disposed on the upper portion of the hydraulic jack and transmits the sensed weight to a control means (not shown). The control means (not shown) compares the sensed weight with a predetermined critical interval It is possible to determine whether the respective shutoff valve valves 511a, 511b and 511c are opened or closed according to the result.

For example, if the control means (not shown) determines that the weight of the object is included in the relatively lighter first critical section, all of the shutoff valves 511a, 511b, 511c are opened, It is possible to control the lift height of the hydraulic jack 3 in accordance with the turning operation to be relatively low. On the other hand, if the control means (not shown) confirms that the object is included in the second critical section, which is relatively heavy, the at least one shut-off valve 511a, 511b, 511c is opened, It is possible to control the lift height of the hydraulic jack 3 to be relatively low. This is because, when the weight of the object is relatively light, the object can be separated from the hydraulic jack in the ascending process. If the weight of the object is comparatively heavy, the possibility of leaving the hydraulic jack in the ascending process is relatively low, to be.

As described above, the hydraulic jack according to another embodiment of the present invention can vary the lifting force of the lifting piston 120 according to the type of object, the type of work,

Meanwhile, the non-ferrous separator 1000 according to an embodiment of the present invention may further include a vibration damping unit. The vibration damping unit is installed at a portion where the size separator 30 and the magnet separator 50 are connected to the body frame 10 so that vibrations occurring between the magnitude separator 30 and the magnet separator 50 and the body frame 10 Lt; / RTI > In the present invention, it is possible to solve the problems including the vibration damping part and the damage or detachment of the respective structures by vibration.

At least a part of the structure of the non-ferrous metal separator 1000 according to one embodiment of the present invention may be realized by a plastic sheet manufactured by the method of manufacturing a plastic sheet according to an embodiment of the present invention as follows.

A method of manufacturing a plastic sheet according to an embodiment of the present invention includes the steps of: 100 parts by weight of a polyethylene terephthalate (PET) resin; 2 to 4 parts by weight of a polyurethane dispersant; and polyethylene dioxythiophene 0.1 to 0.2 part by weight of polystyrene sulfonate, 3 to 5 parts by weight of polystyrolsulfonic acid, N-methyl-2-pyrrolidone, 0.1 to 0.1 part by weight of triethyl amine 0.1 ~ 0.3 part by weight, 42 ~ 45 parts by weight of isopropyl alcohol and 50 ~ 52 parts by weight of water to prepare a mixed composition; A second step of preheating the mixed composition; A third step of removing moisture from the preheated mixed composition; A fourth step of heating the moisture-removed mixed composition; A fifth step of removing foreign substances from the heated mixed composition; A sixth step of preparing a plastic sheet by stretching the mixed composition from which foreign matters have been removed; And a seventh step of applying silicone to the plastic sheet, followed by drying. The present invention can produce a plastic sheet excellent in moldability and durability by mixing various additives with conventional PET resin and preheating, dehumidifying, heating and cooling.

In the first step, as the mixing step of the raw materials, polyethylene terephthalate (PET) resin is used as a base resin, and a polyurethane dispersant, polyethylene dioxythiophene polystyrene sulfonate, Is a step of mixing poly (styrol sulfonic acid), N-methyl-2-pyrrolidone, triethyl amine, isopropyl alcohol and water.

The PET resin is a base resin, which has excellent thermal stability and high crystallinity, can be recycled, and is manufactured in a master batch form. The polyurethane dispersant functions to improve the compatibility with other components. Polyethylene dioxythiophene polystyrene sulfonate, polystyrolsulfonic acid, N-methyl-2-pyrrolidone, and triethyl amine. Function as an antistatic agent. Since the plastic sheet for producing the plastic container is generally an electrical insulator, static electricity is generated by friction charging, and if it is seriously damaged by discharge or electric conduction, it may lead to an accident such as explosion or fire, so it is preferable to add a charging agent . Isopropyl alcohol functions as an antifogging agent. The anti-fogging agent can inhibit the formation of water droplets due to the water vapor which may be generated when a plastic container is used to store a fruit or the like by using a plastic sheet.

For example, the above-mentioned raw materials may be used in an amount of 2 to 4 parts by weight of a polyurethane dispersant, 0.1 part by weight of polyethylene dioxythiophene polystyrene sulfonate (hereinafter referred to as " polyethylene dioxythiophene polystyrene sulfonate ") of 100 parts by weight of polyethylene terephthalate , 0.4 to 0.6 parts by weight of polystyrolsulfonic acid, 3 to 5 parts by weight of N-methyl-2-pyrrolidone, 3 to 5 parts by weight of triethylamine, 0.1 to 0.3 parts by weight, 42 to 45 parts by weight of isopropyl alcohol and 50 to 52 parts by weight of water. When added beyond the above-mentioned range, various problems may occur. Particularly, in the case of an antistatic agent, when mixed over the respective ranges, the plastic surface to be produced may be sticky, the sealing property and printability may be deteriorated, and in the case of white plastic, yellowing may occur.

In addition, the first step may further incorporate various additional ingredients into the raw materials to enhance the functionality of the plastic sheet.

As an example, a boron-based binder may be further mixed. The boron (B) type binder is used for bonding the respective components, and the boron type binder is preferably mixed in 2 to 10 parts by weight with respect to 100 parts by weight of the PET resin. When the content of the boron-based binder is less than 2 parts by weight, the raw material or the like can not be effectively bonded, and when the content of the boron-based binder exceeds 70 parts by weight, it is uneconomical.

As an example, garlic extract may be further mixed. The garlic extract is a natural adhesive component, which together with the boron-based binder functions as a binder which improves the compatibility with other constituents. The garlic extract is peeled and crushed, and 2 to 3 parts by weight of water is added per 1 part by weight of garlic. After heating at 80 to 100 캜 for 5 hours or more, the liquid component is extracted and filtered, The liquid component can be prepared by concentrating at 55 to 60 占 폚. The garlic extract is preferably mixed in 5 to 10 parts by weight with respect to 100 parts by weight of the PET resin. When the content of the garlic extract is less than 5 parts by weight, the raw material components may not be properly entangled so that the surface of the plastic sheet may not be uniformly formed. When the amount of the garlic extract is more than 10 parts by weight, There is a risk of degradation.

As an example, the apatite powder may be further mixed. The apatite powder functions as a filler and can maintain the shape of the plastic sheet, thereby improving workability and improving strength and corrosion resistance. Apatite is an inorganic substance present in bone. It is important to use a small amount of particles, a high residual amount of carbonate, and low crystallinity for use as a filler. Preferably, the size of the apatite granules is 200 to 400 탆. For this purpose, it is important to carry out the sintering process at 500 to 700 ° C. When sintering at less than 500 ° C, there is a disadvantage in that the desired granule size and crystallinity can not be obtained. When sintering exceeds 700 ° C, there is a disadvantage in that the remaining amount of carbonate is low and the crystallinity becomes too high. The apatite powder is preferably mixed in 20 to 30 parts by weight with respect to 100 parts by weight of the PET resin.

When the content of the apatite powder is less than 20 parts by weight, there is a disadvantage in that the adhesive strength is lowered, and when it exceeds 30 parts by weight, the impact resistance is weakened.

As an example, cork powder can be further mixed. Cork powder can improve the durability of the plastic sheet with apatite powder. The cork powder can be prepared by removing the shell of oak oak and then crushing it. For the cork powder to be mixed with the PET resin and the like, it is preferable to use fine pulverized particles which have been passed through a mesh of 400 mesh or more. The cork powder is preferably mixed in 15 to 25 parts by weight with respect to 100 parts by weight of the PET resin. When the cork powder is less than 15 parts by weight, improvement in durability is insignificant. When the cork powder is more than 25 parts by weight, porosity may be formed in the production of plastics, and durability may be lowered.

As an example, the Sorghum extract can be further blended. Sorghum extract not only acts as an antimicrobial agent but also inhibits the yellowing of white plastic sheets. Rumex crispus is a genus of Rumex spp. It is a perennial herb that grows well in moist places of various places. It uses the lysoon as a food in the private sector. In the oriental medicine, it is called a yosei, and it is categorized into various diseases including cystitis, gallbladder disease, bile secretion disorder, spleen disease, It is used as an adjuvant treatment for tumors and cancer. Sorghum extract extracted from Sora japonica has antimicrobial and antioxidant effects against various microorganisms. When mixed with a small amount of sulfur, it has an excellent effect on skin itching. It has been reported that saponins, tannins, flavonoids, essential oils and chrysophanol, and anthraquinone derivatives such as emodin, are known to be useful components of the present invention. The extracts of Sorae Seedlings were washed in 80% (v / v) methanol for 3 days as an extraction solvent by washing the collected Sorghum wells and then drying them in the shade and dividing them into the ground part (except the root) and the root part (root part) After soaking, the extract is filtered with a membrane filter (pore size 0.5 mu m) to separate the solid, and the methanol extract can be prepared by concentrating the extract at 50 DEG C using a rotary evaporator. It is preferable that the Sorghum extract is mixed in 3 to 8 parts by weight with respect to 100 parts by weight of the PET resin. When the content of the extract is less than 3 parts by weight, the antimicrobial activity is insufficient in preventing yellowing, and when it is more than 8 parts by weight, it is uneconomical.

The second step is a step of preheating the mixed composition, and heat is applied to the mixed material so that the materials are stably mixed.

Preferably, the third step is a dehumidifying step of removing moisture present in the preheated mixed composition, and the desiccation is preferably performed in a temperature range of 150 to 180 ° C. If the amount is less than or more than the above range, the dehumidification may not be sufficiently performed, or the durability of the plastic may be adversely affected.

The fourth step is a step of heating the mixed composition from which the moisture has been removed, and the heating temperature is preferably controlled to 260 to 270 ° C in order to melt and maintain the mixed composition.

The fifth step is a step of removing the foreign substance of the heated mixed composition, and it is possible to remove the foreign matter in the inside of the mixed composition by passing it through a screen in the form of a mesh.

The sixth step is a step of cooling the mixed composition from which the foreign substances have been removed to prepare a plastic sheet, which is then drawn in two stages using a cooling roll. The primary stretching takes place in the longitudinal direction through a chill roll maintained at 16-17 캜 and the secondary stretching takes place in the width direction (vertical direction in the longitudinal direction) through a cooling roll maintained at 20-23 캜. The reason for raising the temperature of the secondary elongation to be higher than the primary elongation temperature is to prevent the plasticizability of the solidified plastic sheet from being dried and to improve the durability and moldability of the plastic sheet by alternately stretching the longitudinal direction and the width direction .

The seventh step is a step of applying the silicone to the plastic sheet and then drying it, and the antistatic effect can be obtained at the same time as the finishing treatment is performed by applying the silicone. It is preferable that silicone is applied using a diluted coating liquid in a concentration range of 5 to 25%, coated with silicone, and then dried at 160 to 215 캜. Further, it is preferable that the anti-fogging agent component is mixed with the silicone-containing coating liquid in order to suppress the water phenomenon formed in the produced plastic container.

Hereinafter, the structure and effects of the present invention will be described in more detail with reference to specific examples and comparative examples.
