[0002] With the development of the economy, people's living standards have been increasing day by day. While meeting the basic material needs, people also have higher requirements for their own physical health. Protein bars are small foods that supplement protein. They are packaged like biscuits, and the protein content is about 20 grams, which can supplement protein in a timely manner. Protein bars are helpful for athletes, fitness enthusiasts, and outdoor activity enthusiasts.

[0003] The mixing technology in the production and processing of nutritional protein bars is a complex and crucial process. By reasonably selecting raw materials, scientifically designing formulas, strictly controlling the mixing process and quality control, etc., high-quality nutritional protein bar products can be produced.

Detailed implementation manners

[0038] The technical solution of the present invention will be further specifically described below through embodiments in combination with the accompanying drawings. Many specific details are set forth in the following description to facilitate a full understanding of the invention patent. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific implementations disclosed below.

Therefore, it should not be construed as a limitation to the invention patent. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood through specific situations.

[0040] To facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant accompanying drawings. The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0041] Embodiment example Figures 1 - 11 As shown, a mixing device for the production and processing of nutritional protein bars includes: a mixing barrel 1, a barrel cover 2, a feeding mechanism, a mixing mechanism, and a discharging mechanism. Three legs are provided at the lower end of the mixing barrel 1, and the barrel cover 2 is fixedly installed at the upper end of the mixing barrel 1;

[0042] As Figures 4 - 6As shown in the figure, the mixing mechanism includes an outer mixing frame 7, an inner mixing frame 9, a first motor 15, a first bevel gear 16, and a second bevel gear 17. The outer mixing frame 7 is rotatably installed at the center of the barrel cover 2 through a hollow shaft at the upper end. A second bevel gear 17 is fixedly installed on the hollow shaft at the upper end of the outer mixing frame 7. Several mixing plates are provided on both sides inside the outer mixing frame 7. The inner mixing frame 9 is rotatably installed inside the hollow shaft of the outer mixing frame 7 through a rotating shaft at the upper end. Several mixing plates are provided on both sides outside the inner mixing frame 9. A first bevel gear 16 is fixedly installed on the rotating shaft at the upper end of the inner mixing frame 9. The first motor 15 is fixedly installed on the barrel cover 2, and a bevel gear is fixedly installed on the motor shaft of the first motor 15. The upper and lower sides of this bevel gear are respectively meshed with the first bevel gear 16 and the second bevel gear 17. When horizontal mixing of raw materials is required, the first motor 15 operates to drive the bevel gear on the motor shaft of the first motor 15 to rotate. The bevel gear on the first motor 15 drives the first bevel gear 16 and the second bevel gear 17 to rotate in opposite directions. The first bevel gear 16 drives the inner mixing frame 9 and the mixing plates on the inner mixing frame 9 to rotate, and the second bevel gear 17 drives the outer mixing frame 7 and the mixing plates on the outer mixing frame 7 to rotate. The mixing plates on the inner mixing frame 9 and the mixing plates on the outer mixing frame 7 rotate in opposite directions to mix the raw materials.

[0043] In an alternative embodiment of the present invention, as Figure 6 shown, the inclination directions of the mixing plates on the outer mixing frame 7 and the inner mixing frame 9 are opposite, enhancing the mixing effect.

[0044] In an alternative embodiment of the present invention, as Figures 4 - 6 shown, the mixing mechanism further includes a support rod 8, a vertical stirring frame 10, a stirring shovel 11, a control frame 12, and a second electric cylinder 14. The support rod 8 is fixedly welded to the outer mixing frame 7, and the support rod 8 and the outer mixing frame 7 are in a cross shape. Several stirring shovels 11 are rotatably installed on both sides of the support rod 8. Two vertical stirring frames 10 are rotatably installed inside the inner mixing frame 9 through rotating shafts, and an in-built motor is provided at the rotating shaft of the vertical stirring frame 10. The control frame 12 is slidably installed in a square hole on the barrel cover 2. Vertical grooves corresponding to the stirring shovels 11 are provided on the vertical rods on both sides of the control frame 12. The second electric cylinder 14 is fixedly installed on the upper end surface of the barrel cover 2, and the telescopic rod of the second electric cylinder 14 is fixedly connected to the control frame 12. Since different raw materials are put in at different times, different raw materials may be at different heights, and vertical mixing of the raw materials is required. The second electric cylinder 14 operates to drive the control frame 12 to move up and down. Due to the limitation of the vertical grooves on the control frame 12 on the stirring shovels 11, the stirring shovels 11 rotate around the axis, dialing the raw materials on the outside to the inside. The upper and lower two vertical stirring frames 10 rotate through the in-built motors, and the rotation directions of the upper and lower two vertical stirring frames 10 are opposite, mixing the raw materials in the vertical direction.

[0045] In an alternative embodiment of the present invention, spiral curved surface sheets are provided on the vertical stirring frame 10.

[0046] In an alternative embodiment of the present invention, as Figures 4 - 5 shown, a herringbone groove 13 corresponding to the stirring shovel 11 is provided inside the control frame 12. When the mixing in the vertical direction is not required, the electric cylinder two 14 drives the control frame 12 to move upward. Due to the limitation of the vertical groove on the control frame 12 on the stirring shovel 11, the stirring shovel 11 rotates around the axis until the inclined surface of the stirring shovel 11 is parallel to the herringbone groove 13. When the outer mixing frame 7 drives the support rod 8 to rotate, the support rod 8 drives the stirring shovel 11 to rotate out of the herringbone groove 13, preventing the control frame 12 from jamming the stirring shovel 11.

[0047] In an alternative embodiment of the present invention, as Figures 2 - 3 shown, the feeding mechanism includes a feeding bin 3, an electric cylinder one 4, a feeding adjustment plate 5, and a lifting plate 6; the feeding bin 3 is fixedly installed on the upper end surface of the barrel cover 2, the electric cylinder one 4 is fixedly installed on the barrel cover 2, the telescopic rod of the electric cylinder one 4 is fixedly connected to the feeding adjustment plate 5, the feeding adjustment plate 5 is slidably installed in the chute on the side of the feeding bin 3, the lifting plate 6 is slidably installed in the vertical chute of the feeding bin 3, a spring is provided at the upper end of the lifting plate 6, and the upper end of the spring is fixedly connected to the feeding bin 3; when raw materials need to be discharged, the electric cylinder one 4 works to contract the telescopic rod and drive the feeding adjustment plate 5 to move leftward, thereby controlling the size of the leakage opening below the feeding bin 3. As the feeding adjustment plate 5 moves, the spring on the lifting plate 6 elongates, so as to ensure that the lower end of the lifting plate 6 is always in contact, preventing raw materials from leaking out from the side.

[0048] In an alternative embodiment of the present invention, as Figure 3 shown, the upper end surface of the feeding adjustment plate 5 is an inclined surface, and the lower end surface of the lifting plate 6 is in contact with the inclined surface of the feeding adjustment plate 5.

[0049] In an alternative embodiment of the present invention, as Figures 7 - 11 shown, the discharging mechanism includes a bottom cover one 18, a bottom cover two 19, a bottom cover three 20, a long shaft 21, a lifting assembly, and a rotating assembly; the bottom cover one 18 is movably installed at the bottom of the barrel cover 2, the bottom cover two 19 is movably installed inside the bottom cover one 18, the bottom cover three 20 is movably installed inside the bottom cover two 19, and the lower end surface of the bottom cover three 20 is fixedly installed with a long shaft 21;

The motor shaft of the motor two 22 is fixedly connected to the center of the turntable 23. The other side of the turntable 23 is provided with a centrifugal column 27. The centrifugal column 27 is located at the edge of the turntable 23. One end of the movable member 24 is a strip-shaped chute, and the other end of the movable member 24 is a hollow cylinder. The centrifugal column 27 is slidably matched with the strip-shaped chute on the movable member 24;

[0051] The second motor 22 in the first lifting assembly is fixedly installed at the lower end of the bucket cover 2. The turntable 23 is rotatably installed at the lower end of the bucket cover 2. The strip-shaped chute on the movable member 24 is slidably installed in the vertical chute on the lower end surface of the bucket cover 2. The hollow cylinder on the movable member 24 is rotatably connected to the short shaft on one side of the lower end surface of the first bottom cover 18;

[0052] The second motor 22 in the second lifting assembly is fixedly installed at the lower end of the first bottom cover 18. The turntable 23 is rotatably installed at the lower end of the first bottom cover 18. The strip-shaped chute on the movable member 24 is slidably installed in the vertical chute on the lower end surface of the first bottom cover 18. The hollow cylinder on the movable member 24 is rotatably connected to the short shaft on one side of the lower end surface of the second bottom cover 19;

[0053] The second motor 22 in the third lifting assembly is fixedly installed at the lower end of the second bottom cover 19. The turntable 23 is rotatably installed at the lower end of the second bottom cover 19. The strip-shaped chute on the movable member 24 is slidably installed in the vertical chute on the lower end surface of the second bottom cover 19. The hollow cylinder on the movable member 24 is rotatably connected to the long shaft 21 at the lower end of the third bottom cover 20;

[0054] There are three groups of rotating assemblies. Each group of rotating assemblies includes a third motor 25 and a slider 26. The third motor 25 is fixedly installed on the support plate of the slider 26. A spring group is provided at the lower end of the slider 26. The slider 26 in the first rotating assembly is slidably installed in the vertical frame of the bucket cover 2. The lower end of the spring group on the slider 26 is fixedly connected to the vertical frame of the bucket cover 2. The motor shaft of the third motor 25 is fixedly connected to the short shaft on the other side of the lower end surface of the first bottom cover 18. The first rotating assembly and the first lifting assembly are placed opposite to each other;

[0055] The slider 26 in the second rotating assembly is slidably installed in the vertical frame of the first bottom cover 18. The lower end of the spring group on the slider 26 is fixedly connected to the vertical frame of the first bottom cover 18. The motor shaft of the third motor 25 is fixedly connected to the short shaft on the other side of the lower end surface of the second bottom cover 19. The second rotating assembly and the second lifting assembly are placed opposite to each other;

[0056] The slider 26 in the third rotating assembly is slidably installed in the vertical frame of the second bottom cover 19. The lower end of the spring group on the slider 26 is fixedly connected to the vertical frame of the second bottom cover 19. The motor shaft of the third motor 25 is fixedly connected to the long shaft 21 at the lower end of the third bottom cover 20. The third rotating assembly and the third lifting assembly are placed opposite to each other;

[0057] The motor two 22 in the third lifting component operates to drive the turntable 23 to rotate. The centrifugal columns 27 on the turntable 23 drive the movable part 24 to move downward. The movable part 24 drives the bottom cover three 20 to descend and separate from the bottom cover two 19. Then, the motor three 25 in the third rotating component is used to make the bottom cover three 20 rotate and tilt around the long axis 21 to pour out the materials in the central part. Similarly, then the bottom cover two 19 is made to descend and separate from the bottom cover one 18 through the second lifting component, and then the bottom cover two 19 is rotated and tilted around the short axis by using the second rotating component to pour out the materials on the bottom cover two 19. Later, the bottom cover one 18 is made to descend and separate from the barrel cover 2 through the first lifting component, and then the bottom cover one 18 is rotated and tilted around the short axis by using the second rotating component to pour out the materials on the bottom cover one 18. By pouring out the mixed materials step by step, it is prevented that too much materials are fed at one time, causing impact.

[0058] Working principle: When using this equipment, when raw materials need to be put in, the electric cylinder one 4 operates to contract the telescopic rod and drive the feeding adjusting plate 5 to move leftward, thereby controlling the size of the leakage opening below the feeding bin 3. As the feeding adjusting plate 5 moves, the spring on the lifting plate 6 elongates, so as to ensure that the lower end of the lifting plate 6 is always in contact, preventing raw materials from leaking out from the side. The raw materials are put into the inside of the mixing barrel 1 from above the feeding bin 3.

[0059] Since different raw materials are put in at different times and may be at different heights, it is necessary to mix the raw materials in the vertical direction. The electric cylinder two 14 operates to drive the control frame 12 to move up and down. Due to the limitation of the vertical groove on the control frame 12 on the stirring shovel 11, the stirring shovel 11 rotates around the axis, and the raw materials on the outside are dialed towards the inside. The upper and lower vertical stirring frames 10 rotate through the built-in motor, and the rotation directions of the upper and lower vertical stirring frames 10 are opposite to mix the raw materials in the vertical direction.

[0060] When vertical mixing of raw materials is not required, the electric cylinder two 14 drives the control frame 12 to move upward. Due to the limitation of the vertical groove on the control frame 12 on the stirring shovel 11, the stirring shovel 11 rotates around the axis until the inclined surface of the stirring shovel 11 is parallel to the herringbone groove 13. When the horizontal mixing outer mixing frame 7 drives the support rod 8 to rotate, the support rod 8 drives the stirring shovel 11 to be able to rotate out from the herringbone groove 13 to prevent the control frame 12 from jamming the stirring shovel 11.

[0061] When horizontal mixing of raw materials is required, the motor one 15 operates to drive the bevel gear on the rotating shaft of the motor one 15 to rotate. The bevel gear on the motor one 15 drives the bevel gear one 16 and the bevel gear two 17 to rotate in opposite directions. The bevel gear one 16 drives the inner mixing frame 9 and the mixing plates on the inner mixing frame 9 to rotate. The bevel gear two 17 drives the outer mixing frame 7 and the mixing plates on the outer mixing frame 7 to rotate. The mixing plates on the inner mixing frame 9 and the outer mixing frame 7 rotate in opposite directions to mix the raw materials.

[0062] After the mixing is completed, the third lifting component is used to lower the bottom cover three 20 away from the bottom cover two 19, and then the third rotating component is used to rotate and tilt the bottom cover three 20 around the long axis 21 to pour out the material in the central part; then the second lifting component is used to lower the bottom cover two 19 away from the bottom cover one 18, and then the second rotating component is used to rotate and tilt the bottom cover two 19 around the short axis to pour out the material on the bottom cover two 19; finally, the first lifting component is used to lower the bottom cover one 18 away from the barrel cover 2, and then the second rotating component is used to rotate and tilt the bottom cover one 18 around the short axis to pour out the material on the bottom cover one 18. By pouring out the mixed material step by step, it is possible to prevent excessive impact caused by excessive one-time feeding.

[0063] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes may be made therein without departing from the principles and spirit of the invention, and the scope of the invention is defined by the appended claims and their equivalents.
