[0035] In addition, in the following description of the present invention, configurations that are deemed to make the gist of the present invention unclear, for example, detailed descriptions of well-known techniques including conventional techniques, may be omitted.

[0036] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the associated drawings.

[0037] FIG. 2 is a perspective view of the powder mixer according to the present invention as viewed from the front, and FIG. 3 is a perspective view of the powder mixer according to the present invention as viewed from the rear.

[0038] Referring to Figures 2 and 3, the powder mixer 1000 according to the present invention includes a work table 100, a housing unit 200, a driving unit 300, a control unit 400, a binder tank 500, a discharge unit 600, a fixing unit 700, a spray nozzle 800, and an air valve 900.

[0039] The work table 100 serves to support the various components that make up the powder mixing apparatus 1000 .

[0040] These work tables allow workers to work in an upright position, greatly improving the working environment compared to working without a work table.

[0041] The housing portion 200 functions to mix the provided raw materials (powder).

[0042] These housing parts 200 have a cylindrical shape with an open top, and the open top of the housing part 200 is sealed by a cover 220 which will be described later.

[0043] In order to prevent the temperature of the housing part 200 from increasing during mixing of the raw materials, the outer surface of the housing part 200 may further include a cooling part (not shown).

[0044] These cooling sections serve to lower the temperature of the housing section 200 when the temperature of the housing section 200 rises, and may include Peltier elements for temperature control, which maintain the internal temperature of the housing section 200 at a constant temperature.

[0045] The cooling unit may include a Peltier element to maintain the internal temperature of the housing unit 200 at a constant temperature, and the cooling unit may be formed in a structure in which the Peltier element is positioned at the center, heat sinks are provided on both sides, and a fan unit is provided on the outside of the heat sinks to flow heated and cooled air into or out of the housing unit 200.

[0046] Here, a Peltier element can be used to adjust the temperature.

[0047] A Peltier element is an element that uses the Peltier effect to maintain a temperature difference across the element.

[0048] The Peltier effect is a phenomenon in which a temperature difference is sustained across multiple layers of conductive material when an electric current is passed through them, and devices that utilize this effect are called Peltier devices or thermoelectric devices.

[0049] That is, when the high temperature part on the opposite side that requires low temperature cooling is forcibly cooled, the heat of the low temperature part is transferred to the high temperature part, and the temperature of both Peltier elements can be adjusted according to the direction of the applied current. One side of the powder mixer 1000 according to an embodiment of the present invention is provided with a Peltier element, a heat sink, and a fan, and when the temperature inside the housing part 200 rises above an appropriate temperature, the Peltier element part on the housing part 200 side is cooled and cooled air is introduced by the fan unit, thereby lowering the internal temperature of the housing part 200. When the temperature inside the housing part 200 falls below an appropriate temperature, the Peltier element part on the housing part 200 side is heated and heated air is introduced by the fan unit, thereby raising the internal temperature of the housing part 200. Thus, the internal temperature of the housing part 200 can be maintained within a preset appropriate temperature range.

[0050] On the other hand, the driving section 300 serves to drive the impeller section 210, which will be described later.

[0051] These driving units 300 are formed in the shape of a rectangular prism box, and a first driving motor 310 and a second driving motor 320, which will be described later, are attached inside this box.

[0052] The control unit 400 is configured as a monitor and serves to control the various functions and all the components of the powder mixing device 1000 according to the present invention.

[0053] These control units 400 can be controlled by a touch screen, and can be controlled by an administrator who manages the powder mixing apparatus 1000.

[0054] The binder tank 500 serves as an auxiliary raw material input.

[0055] The discharge portion 600 serves to discharge the ingredients mixed within the housing portion 200 .

[0056] These discharge portions 600 are installed on the side surfaces of the housing portion 200 and are formed to be inclined in a direction lower than the height of the housing portion 200 .

[0057] Therefore, a user can collect the mixed ingredients discharged from the housing part 200 by placing a collecting container or the like under the discharge part 600 .

[0058] A plurality of fixing parts 700 are attached to the lower part of the working table 100 to support the working table and to fix the powder mixer 1000 in place.

[0059] On the other hand, the powder mixing apparatus 1000 may further include a moving part (not shown) near the fixed part 700, and the position of the powder mixing apparatus 1000 can be moved via the moving part.

[0060] The spray nozzle 800 is connected to the lower portion of the binder tank 500 and the housing part 200 through a hole formed in the lid 220 that seals the housing part 200 .

[0061] Auxiliary materials such as oil from the binder tank 500 are sprayed uniformly from top to bottom into the housing portion 200 through these spray nozzles 800, which has the effect of preventing the materials being mixed within the housing portion 200 from solidifying.

[0062] In this manner, the auxiliary material such as oil is sprayed uniformly from the top to the bottom by the spray nozzle 800 under the control of the control unit 400 .

[0063] Air can also be injected into the housing portion 200 via a spray nozzle 800 .

[0064] The air is regulated by an air valve 900 on the binder tank 500 and is injected into the housing portion 200 by a spray nozzle 800 .

[0065] The air valve 900 is controlled by an administrator via the control unit 400 .

[0066] More specifically, the main components of the powder mixing device 1000 according to the present invention include a work table 100 , a housing portion 200 , an impeller portion 210 , a cover 220 , and a driving portion 300 .

[0067] The housing part 200 is located on one side of the working table 100, and the provided ingredients are mixed.

[0068] The impeller unit 210 is connected to the lower part of the housing unit 200 and serves to mix the raw materials input into the housing unit 200 .

[0069] The cover 220 covers the upper part of the housing portion 200 .

[0070] The driving unit 300 is located on the other side of the work table 100 and serves to drive the impeller unit 210 .

[0071] Also, the discharge part 600 is installed on the side of the housing part 200 and serves to discharge the ingredients mixed within the housing part 200 .

[0072] In addition, the binder tank 500 is installed on the upper part of the driving part 300 and serves as an auxiliary raw material input part into which the auxiliary raw material is input.

[0073] Meanwhile, spray nozzles 800 may be connected between the binder tank 500 and the cover 220, and these spray nozzles 800 serve to uniformly spray auxiliary materials such as oil from the top to the bottom within the housing part 200 or to inject air.

[0074] FIG. 4 is a diagram showing the driving relationship between the drive unit and the impeller unit in the powder mixer according to the present invention.

[0075] Referring to FIG. 4, the driving unit 300 of the powder mixing apparatus 1000 according to the present invention drives the impeller unit 210 .

[0076] The driving unit 300 includes a first driving motor 310 that drives a first rotating shaft 211, which will be described later.

[0077] The driving unit 300 also includes a second driving motor 311 that drives a second rotating shaft 212, which will be described later.

[0078] At this time, a first drive motor 310 and a second drive motor 320 are installed within the drive unit 300, and these first drive motor 310 and second drive motor 320 are connected to the impeller unit 210 by a pulley 320 to drive the impeller unit 210.

[0079] More specifically, the first impeller 211 and the second impeller 212 of the impeller unit 210 are driven.

[0080] These pulleys 320 are cylindrical wheels around which a belt is hung, and are also called belt wheels.

[0081] This refers to the friction wheels used on the driving and driven shafts in winding transmission, and there are types for flat belts, V-belts, toothed belts, etc.

[0082] Flat belt gears are generally cylindrical, but when the speed ratio is to be changed continuously, conical gears are used, and when the speed ratio is to be changed in stages, single gears are used.

[0083] In the case of a flat belt, the outer surface of the pulley may be flat, but generally, if the center portion is made slightly higher, the belt is less likely to come off.

[0084] In terms of structure, there are split and integrated types.

[0085] They are usually made of cast iron, but for high-speed ones light alloys or iron plate are used, and they may also be made of wood for lighter tightening.

[0086] In this manner, the rotational force generated by the first drive motor 310 and the second drive motor 320 rotates the first impeller 211 and the second impeller 212 of the impeller section 210 via the pulley 320 .

[0087] Of course, since there are two drive motors in the drive section 300 and two impellers in the impeller section 210, there are also two pulleys 320.

[0088] That is, the first drive motor 310 rotates the first impeller 211 by means of the first pulley, and the second drive motor 311 rotates the second impeller 212 by means of the second pulley.

[0089] More specifically, the first drive motor 310 rotates the first rotating shaft 211 by means of a first pulley, and the second drive motor 311 rotates the second rotating shaft 212 by means of a second pulley.

[0090] FIG. 5 is a diagram showing the inside of a housing part of the powder mixer according to the present invention.

[0091] Referring to FIG. 5, the inside of the housing part 200 and the impeller part 210 of the powder mixer 1000 according to the present invention can be seen.

[0092] A bias prevention portion 240 is located inside the housing portion 200, and an impeller 230 is located inside the impeller portion 210.

[0093] The bias prevention members 240 will be described in more detail with reference to FIG. 6, and the impeller 230 will be described in more detail with reference to FIG.

[0094] FIG. 6 is a perspective view showing a bias prevention unit in the powder mixer according to the present invention.

[0095] Referring to FIG. 6, the bias prevention portion 240 of the powder mixing device 1000 according to the present invention includes a support bar 241 and a bias prevention surface 242 .

[0096] These bias prevention members 240 are coupled to the inner surface of the cover 220 .

[0097] That is, the bias prevention part 240 has a support rod 241 one side of which is connected to the cover 220, and a bias prevention surface 242 formed on the other side of the support rod 241 and curved inward.

[0098] One side of the support rod 241 of the bias prevention part 240 is connected to the cover 220 .

[0099] The manner in which one side of the support rod 241 is connected to the cover 220 may vary.

[0100] For example, the connection may be made by a screw connection method, but is not limited to this, and various connection methods may be used for connection.

[0101] On the other hand, the bias prevention surface 242 is formed on the other side of the support rod 241 and is formed in a curved shape.

[0102] In particular, the curved shape of the bias prevention surface 242 has a curved shape that curves toward the inside of the housing portion 200.

[0103] Due to the centrifugal force generated by the rotation of the impeller 230, the raw materials mixed inside the housing part 200 may be biased toward the outside of the housing part 200.

[0104] At this time, the raw material biased toward the outside due to the centrifugal force collides with the bias prevention surface 242 and moves further toward the inside of the housing portion 200.

[0105] As described above, the bias prevention unit 240 of the powder mixer 1000 according to the present invention has an effect of preventing the material being mixed inside the housing unit 200 from being biased toward the outside of the housing unit 200 due to centrifugal force.

[0106] On the other hand, these bias prevention units 240 may further include a temperature sensor (not shown).

[0107] These temperature sensors sense the temperature inside the housing 200 while the ingredients are being mixed and display it on the control unit 400, thereby preventing the ingredients from burning or discoloring while being mixed.

[0108] FIG. 7 is a perspective view showing an impeller portion of the powder mixer according to the present invention.

[0109] Referring to FIG. 7, an impeller unit 210 of a powder mixing apparatus 1000 according to the present invention includes a first rotating shaft 211, a second rotating shaft 212, and an impeller 230 having a first impeller 231 and a second impeller 232.

[0110] When the first drive motor 310 is driven, the driving force of the first drive motor 310 is transmitted to the first rotation shaft 211 by the first pulley, causing the first rotation shaft 211 to rotate.

[0111] Furthermore, when the second drive motor 311 is driven, the driving force of the second drive motor 311 is transmitted to the second rotation shaft 212 by the second pulley, causing the second rotation shaft 212 to rotate.

[0112] That is, the first impeller 231 and the second impeller 232 rotate due to the rotation of the first rotating shaft 211 and the second rotating shaft 212, respectively.

[0113] By the rotation of the impeller 230 including the first impeller 231 and the second impeller 232, the different raw materials in the housing portion 200, that is, the different powders, are mixed more easily.

[0114] FIG. 8 is a perspective view showing the first impeller and the second impeller in the impeller section of the powder mixer according to the present invention.

[0115] Referring to FIG. 8, the impeller 230 of the powder mixing apparatus 1000 according to the present invention includes a first impeller 231 and a second impeller 232 .

[0116] The first impeller 231 is rotated in one direction by the first rotating shaft 211 driven by the first drive motor 310.

[0117] These first rotating shafts 211 are hollow inside.

[0118] The first impeller 231 has a center portion connected to the first rotating shaft 211 and both ends curved toward the inside of the housing unit 200.

[0119] That is, although it is formed in a bar shape, both ends are bent toward the inside of the housing part 200 and the central part is connected to the first rotating shaft 211.

[0120] As a result, when the first rotating shaft 211 rotates, the first impeller 231 rotates in one direction.

[0121] When these first impellers 231 rotate, the raw materials inside the housing part 200 are mixed, and at this time, the raw materials that sink to the bottom inside the housing part 200 are blown away.

[0122] That is, the first impeller 231 blows away the raw material that sinks to the bottom during mixing of the raw material.

[0123] As a result, the raw materials in the housing part 200 do not sink to the bottom but are blown upward, resulting in an effect of uniformly mixing the raw materials.

[0124] In addition, in the powder mixing apparatus 1000 according to the present invention, the second impeller 232 is formed of a ring shape and a plurality of blades spaced at predetermined intervals along the circumference of the ring, one side of which is connected to the circumference of the ring and the other side of which is connected to the second rotating shaft 212.

[0125] First, in the powder mixer 1000 according to the present invention, the impeller unit 210 includes a second rotating shaft 212 and a second impeller 232 .

[0126] These first rotating shafts 211 are hollow inside.

[0127] The second rotating shaft 212 is inserted into the inside of the first rotating shaft 211 .

[0128] The second impeller 232 is rotated in the other direction by the second rotating shaft 212 driven by the second drive motor 311.

[0129] These second impellers 232 include a ring-shaped and a plurality of bar-shaped blades.

[0130] At this time, one side of each of the blades is connected to the outer periphery of the ring, and the other side is connected to the second rotating shaft 212.

[0131] Of course, one side of each of the blades is connected to the outer periphery of the ring at a predetermined interval along the outer periphery of the ring, and the other side of each of the blades is connected to the outer periphery of the second rotating shaft 212 at a predetermined interval along the outer periphery of the second rotating shaft 212.

[0132] When these second impellers 232 rotate, the ingredients in the housing portion 200 are mixed, and at this time, the ingredients in the housing portion 200 move to the upper or lower portion and are mixed.

[0133] That is, when mixing the raw materials, the second impeller 232 moves the raw materials up and down by the rotational force of the second impeller 232.

[0134] As a result, the ingredients in the housing part 200 move upward or downward and are mixed, so that the ingredients are mixed uniformly.

[0135] Additionally, the first impeller 231 and the second impeller 232 may each include a chopper blade.

[0136] These chopper blades serve to crush the individual raw materials as they are mixed.

[0137] The raw materials are crushed by these chopper blades, which has the effect of uniformly mixing the raw materials.

[0138] In other words, the powder mixer 1000 according to the present invention has a first impeller 231 that rotates in one direction by the rotation of the first rotating shaft 211 driven by the first driving motor 310, and a second impeller 232 that rotates in the other direction by the rotation of the second rotating shaft 212 driven by the second driving motor 311, thereby preventing the uneven distribution of raw materials caused by the centrifugal force due to the rotation of the blades, and by rotating the two impellers in the opposite directions during mixing in the mixer, the raw materials being mixed can be easily mixed together.

[0139] In particular, the second rotating shaft 212 is inserted inside the first rotating shaft 211 and rotates in the opposite directions without affecting each other, which has the effect of allowing the raw materials to be easily mixed with each other.

[0140] In addition, the powder mixer 1000 according to the above-mentioned embodiment requires two driving motors to rotate the second rotating shaft 212 in the other direction when the first rotating shaft 211 is rotated in one direction to easily mix the raw materials with each other.

[0141] That is, the first rotating shaft 211 is rotated in one direction by the first drive motor 310, and the second rotating shaft 212 is rotated in the other direction by the second drive motor 311.

[0142] However, when using two drive motors (the first drive motor 310 and the second drive motor 311) in this manner, space is required within the work table 100 for the two drive motors. In this case, the volume of the powder mixer 1000 increases and the worker's work space may decrease.

[0143] Therefore, another embodiment of the present invention will be described in which a single drive motor is used to facilitate mixing of the ingredients together.

[0144] The configuration of the powder mixer mixer 1000 according to another embodiment of the present invention is very similar to the components of the powder mixer mixer 1000 described above, but uses only one drive motor.

[0145] That is, the driving unit 300 in the powder mixer 1000 according to another embodiment of the present invention includes only one driving motor, which will be described as a first driving motor 310 for ease of explanation.

[0146] As a result, in this embodiment, the first drive motor 310 rotates only the second rotating shaft 212 by means of the first pulley.

[0147] In this configuration, when the second rotary shaft 212 is rotated by the drive of the first drive motor 310, only the second impeller 232 rotates in one direction.

[0148] At this time, the first rotating shaft 211 does not rotate, and the first impeller 231 does not rotate due to the non-rotation of the first rotating shaft 211, and maintains a state in which it is supported by the first rotating shaft.

[0149] With this configuration, when the second impeller 232 rotates in one direction due to the rotation of the second rotating shaft 212, the first impeller 231 supported by the first rotating shaft 211 acts as a barrier that prevents the rotation of the second impeller 232.

[0150] This has the effect of allowing the raw materials to be easily mixed together by the rotation of the first impellers 231 caused by the rotation of the first rotating shaft 211 and the second impeller 232 which prevents the rotation of the first impellers 231 .

[0151] Meanwhile, a powder mixer 1000 according to another embodiment of the present invention will be described, which has a configuration in which a first rotating shaft 211 and a second rotating shaft 212 are rotated in opposite directions using one driving motor, thereby allowing the raw materials to be easily mixed together.

[0152] That is, in this embodiment, a gear may be further included between the first rotating shaft 211 and the second rotating shaft 212.

[0153] First, the first drive motor 310 rotates only the first rotating shaft 211 by means of the first pulley.

[0154] At this time, when the first rotating shaft 211 rotates in one direction, the first impeller 231 rotates and the gear attached between the first rotating shaft 211 and the second rotating shaft 212 also operates.

[0155] By this operation of the gears, the second rotary shaft 212 rotates in the other direction, thereby rotating the second impeller 232 .

[0156] One example of these gears is a geared motor.

[0157] In a configuration in which one motor rotates two rotating shafts in opposite directions, a geared motor can be used to transmit the rotational force of the motor to the two rotating shafts.

[0158] In this case, the geared motor can use multiple types of gears, and a selection can be made according to the desired rotation speed and direction.

[0159] As an example, the geared motor may include a planetary geared motor, a spiral bevel geared motor, a parallel shaft geared motor, a stepper motor geared motor, a worm geared motor, and the like.

[0160] Therefore, two rotating shafts are rotated in opposite directions using only one driving motor, and thus, the first impeller 231 and the second impeller 232 rotating in opposite directions have the effect of easily mixing the raw materials with each other.

[0161] In this way, according to the present invention, it is possible to prevent the uneven distribution of raw materials caused by the centrifugal force generated by the rotation of the blades, and it is also possible to easily mix the raw materials being mixed by rotating the two impellers in the opposite directions during mixing in the mixer.

[0162] The above describes various preferred embodiments of the present invention using some examples. However, the description of the various embodiments described in this section "Form for carrying out the invention" is merely illustrative, and a person having ordinary knowledge in the technical field to which the present invention pertains can understand from the above description that the present invention can be implemented in various modified forms or in an equivalent manner to the present invention.

[0163] Furthermore, the present invention may be embodied in various other forms and is not limited by the above description. The above description is provided to complete the disclosure of the present invention and to fully inform those skilled in the art of the scope of the present invention, and the present invention is defined only by the claims.
