Description
A multi-directional flour mixing device for dough processing Technical Field
[0001] This invention belongs to the field of food processing technology, specifically a multi-directional flour mixing device for dough processing. Background Technology
[0002] In the field of pasta processing, flour mixing is a core process that determines the quality of dough formation and its taste. The mixing effect directly impacts the gluten development, elasticity, and overall quality of subsequent pasta products, and it is widely used in the production of various pasta products such as bread, noodles, and steamed buns. Currently, dough mixing devices, as key equipment in pasta processing, primarily use a mixing shaft to drive mixing blades to act on the mixture of flour and water, ensuring thorough integration and forming a uniform, resilient dough to meet the needs of subsequent shaping, fermentation, and other processing steps.
[0003] Traditional dough mixing devices mostly employ a fixed mixing shaft with multiple mixing blades. This structure only allows the shaft to drive the blades in a single circular rotation, resulting in a limited mixing trajectory. This fails to cover the bottom, walls, and center of the mixing bowl, leading to problems such as bottom dust accumulation, uneven mixing at the edges, and residual dry powder inside. During the unloading process after mixing, the complex design of the mixing structure causes existing devices to suffer from severe dough sticking, binding to the shaft, and being easily lifted by the mixing blades. Because the mixing blades are fixed, when the mixing shaft is lifted, the blades can hook onto the dough, causing it to rise with the shaft. This not only disrupts the overall shape of the dough but also leaves a large amount of dough residue on the shaft and blades, increasing cleaning difficulty and material waste. Therefore, both reliability and practicality are unsatisfactory. Summary of the Invention
[0004] This invention provides a multi-directional flour mixing device for dough processing, which can solve the technical problems of existing mixing devices having a single mixing trajectory and being prone to sticking.
[0005] A multi-directional flour mixing device for dough processing includes a support base and a fixed vertical plate. The fixed vertical plate is fixedly installed on the rear top of the support base. A mixing bucket is fixed to the front of the fixed vertical plate through a flipping mechanism. A mixing mechanism is provided inside the mixing bucket. An up-and-down driving mechanism is connected to the top of the mixing mechanism. A lateral movement mechanism for driving the up-and-down driving mechanism to move laterally is also fixedly installed on the front of the fixed vertical plate. The up-and-down driving mechanism is slidably connected to the fixed vertical plate and is located on one side of the lateral movement mechanism.
[0006] As a further technical solution of the present invention, the flipping mechanism includes two fixed frames and a support plate. The mixing tank is movably installed in the two fixed frames through a rotating shaft. A flipping motor for driving the rotating shaft to rotate is fixedly installed on the outside of one of the fixed frames. The bottom of the support plate is fixed to the top of the fixed frame. A sliding groove for the fixed frame to move down is opened at the front of the fixed vertical plate.
[0007] As a further technical solution of the present invention, a hydraulic cylinder for driving the support plate to move downward is fixedly installed at the front of the fixed vertical plate, and a hydraulic rod is connected between the bottom of the fixed frame and the top of the support base.
[0008] As a further technical solution of the present invention, the stirring mechanism includes a stirring rod, a base plate fixedly connected to the bottom of the stirring rod, and stirring blades rotatably mounted on both sides of the base plate. A support plate is fixedly connected to the top of the stirring rod, and an adjusting rod is threadedly connected to the support plate. The adjusting rod is located inside the stirring rod, and a limiting plate is fixedly connected to its bottom end. A fixed plate is connected to the top of the support plate through a connecting rod, and an installation plate is provided above the fixed plate. A drive motor is fixedly mounted on the top of the installation plate, and the drive shaft of the drive motor is fixedly connected to the fixed plate. A connecting plate is connected to the top of the installation plate through a connecting rod.
[0009] As a further technical solution of the present invention, mounting grooves are provided on both sides of the chassis, one end of the stirring blade is rotatably mounted in the mounting groove via a rotating shaft, and a limiting block for restricting the upward movement of the stirring blade is fixedly installed inside the mounting groove.
[0010] As a further technical solution of the present invention, the adjusting rod is provided with a threaded section that is threadedly connected to the support plate, the limiting plate is provided with arc-shaped surfaces on both sides, and its two sides abut against the lower end surface of the stirring blade, and the top of the adjusting rod is fixedly connected to the adjusting plate.
[0011] As a further technical solution of the present invention, the upper and lower driving mechanism includes a fixed plate, a turntable 1 is rotatably mounted on the front of the fixed plate, and guide blocks are fixedly mounted on the upper and lower ends of the turntable 1 on the front of the fixed plate. A slide rod 1 is slidably connected in the upper guide block, and a slide rod 2 is slidably mounted in the lower guide block. A limit frame is fixedly connected to the top of the slide rod 2. A drive wheel is rotatably mounted on the edge of the turntable 1 and is located in the limit frame. The bottom end of the slide rod 1 is fixed to the top surface of the limit frame. A U-shaped slide seat is fixed at the rear of the fixed plate.
[0012] As a further technical solution of the present invention, a rotary motor for driving the turntable to rotate is installed at the rear of the fixed plate. The rotary motor is located inside the slide block. A slide rail adapted to the slide block is fixedly installed at the front of the fixed vertical plate. The bottom end of the slide rod is fixedly connected to the connecting plate.
[0013] As a further technical solution of the present invention, the transverse movement mechanism includes a disc, a second turntable is rotatably mounted on the front of the disc, and a horizontal plate is fixedly mounted on one side of the disc. Two guide plates are fixedly mounted on the front of the horizontal plate, and a transverse movement rod is slidably mounted inside the two guide plates. A drive rod is connected between one end of the transverse movement rod and the front edge of the disc. Both ends of the drive rod are rotatably connected to the transverse movement rod and the disc respectively through a rotating shaft. A U-shaped fixing seat is fixedly mounted on the rear of the disc.
[0014] As a further technical solution of the present invention, a rotary motor for driving the turntable to rotate is fixedly installed at the rear of the disc. The motor is located inside the fixed seat, and the fixed seat is fixedly connected to the fixed vertical plate. The other end of the horizontal moving rod is fixedly connected to the side wall of the fixed plate. The horizontal plate does not contact the fixed plate, and an L-shaped support rod is fixedly connected between its bottom and the support base.
[0015] The beneficial effects of this invention are as follows: By setting up an up-and-down driving mechanism in conjunction with a transverse movement mechanism, when the stirring blade rotates, the driving turntable one drives the driving wheel to rotate, which in turn drives the limiting frame to move up and down, causing slide rod one and slide rod two to reciprocate up and down, allowing the stirring blade to move up and down. In conjunction with the rotation of turntable two, the driving rod drives the transverse movement rod to drive the fixed plate to reciprocate horizontally, thus allowing the stirring blade to reciprocate horizontally. The stirring blade performs rotational, vertical, and horizontal reciprocating motions relative to the mixing drum, forming a multi-dimensional composite stirring trajectory. This allows for multi-directional stirring within the mixing drum, achieving three-dimensional kneading without dead angles, effectively preventing dry powder residue inside the mixing drum, and improving the dough's forming quality and taste. The mixing blades are movable. During use, the bottom of the mixing blades is limited by a limiting plate, ensuring good stability during mixing. After mixing, the adjusting rod can be rotated to move the limiting plate downwards. As the mixing blades rise, they fold downwards due to the rotation shaft, reducing the distance between the two blades. This reduced distance creates localized shearing force between the blades and the dough, actively cutting off any gluten strands that are stuck together. This effectively prevents large-area adhesion between the dough and the mixing blades and rod. With only two mixing blades, replacement and maintenance are more convenient. This effectively reduces the contact area between the mixing structure and the dough, and avoids excessive dough adhesion after shaping due to a complex mixing structure, thus improving the overall performance of the mixing device.

[0019] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] As shown in Figures 1-7, a multi-directional flour mixing device for dough processing includes a support base 1 and a fixed vertical plate 2. The fixed vertical plate 2 is fixedly installed on the rear top of the support base 1. A mixing bucket 3 is fixed to the front of the fixed vertical plate 2 through a flipping mechanism. A mixing mechanism 6 is provided inside the mixing bucket 3. An up-down driving mechanism 4 is connected to the top of the mixing mechanism 6. A lateral moving mechanism 5 for driving the up-down driving mechanism 4 to move laterally is also fixedly installed on the front of the fixed vertical plate 2. The up-down driving mechanism 4 is slidably connected to the fixed vertical plate 2 and is located on one side of the lateral moving mechanism 5.
[0021] The tilting mechanism includes two fixed frames and a support plate. The mixing tank 3 is movably installed in the two fixed frames via a rotating shaft. A tilting motor for driving the rotating shaft is fixedly installed on the outside of one of the fixed frames. The bottom of the support plate is fixed to the top of the fixed frame. A groove for the fixed frame to move down is opened at the front of the fixed vertical plate 2. A hydraulic cylinder for driving the support plate to move down is fixedly installed at the front of the fixed vertical plate 2. A hydraulic rod is connected between the bottom of the fixed frame and the top of the support base 1.
[0022] Specifically, the hydraulic cylinder drives the support plate to move the fixed frame downward, which lowers the height of the mixing tank 3, making it easier for the mixing blade 604 to detach from its interior and for the dough to be removed after mixing.
[0023] The stirring mechanism 6 includes a stirring rod 601, a base 603 fixedly connected to the bottom of the stirring rod 601, and stirring blades 604 rotatably mounted on both sides of the base 603. A support plate 609 is fixedly connected to the top of the stirring rod 601, and an adjusting rod 602 is internally threaded onto the support plate 609. The adjusting rod 602 is located inside the stirring rod 601, and a limit plate 610 is fixedly connected to its bottom end. A fixed plate 605 is connected to the top of the support plate 609 via a connecting rod. An installation plate 606 is provided on the top, and a drive motor 607 is fixedly installed on the top of the installation plate 606. The drive shaft of the drive motor 607 is fixedly connected to the fixed plate 605, and a connecting plate 608 is connected to the top of the installation plate 606 through a connecting rod. Installation grooves 611 are provided on both sides of the chassis 603. One end of the stirring blade 604 is rotatably installed in the installation groove 611 through a rotating shaft, and a limiting block 612 for restricting the upward movement of the stirring blade 604 is fixedly installed inside the installation groove 611.
[0024] Specifically, the drive motor 607 drives the fixed plate 605 to rotate, which in turn drives the stirring rod 601 and the stirring blade 604 to rotate, thereby stirring the flour. By rotating the adjusting rod 602, the limiting plate 610 can be moved down, so that when the entire stirring rod 601 is lifted, the stirring blade 604 can rotate downward, making it easier to separate from the dough.
[0025] The adjusting rod 602 is provided with a threaded section 613 that is threadedly connected to the support plate 609. The limiting plate 610 is provided with arc-shaped surfaces on both sides, and its two sides abut against the lower end surface of the stirring blade 604. The top of the adjusting rod 602 is fixedly connected to the adjusting plate.
[0026] Specifically, by using a limiting plate 610 to press against the lower end face of the stirring blade 604, and in conjunction with the limiting block 612, the stirring blade 604 can maintain a stable state during stirring.
[0027] The upper and lower drive mechanism 4 includes a fixed plate 41. A turntable 42 is rotatably mounted on the front of the fixed plate 41. Guide blocks 43 are fixedly mounted on the upper and lower ends of the turntable 42 on the front of the fixed plate 41. A slide rod 44 is slidably connected in the upper guide block 43. A slide rod 45 is slidably mounted in the lower guide block 43. A limit frame 47 is fixedly connected to the top of the slide rod 45. A drive wheel 46 is rotatably mounted on the edge of the turntable 42. The drive wheel 46 is located in the limit frame 47. The bottom end of the slide rod 44 is fixed to the top surface of the limit frame 47. A U-shaped slide seat is fixed to the rear of the fixed plate 41.
[0028] A rotary motor is installed at the rear of the fixed plate 41 to drive the turntable 42 to rotate. The rotary motor is located inside the slide. A slide rail adapted to the slide is fixedly installed at the front of the fixed vertical plate 2. The bottom end of the slide rod 45 is fixedly connected to the connecting plate 608.
[0029] Specifically, the rotation of turntable 42 drives the drive wheel 46 to slide within the limiting frame 47, thereby using the limiting frame 47 to drive slide rod 44 and slide rod 45 to move up and down reciprocally, changing the up and down position of the stirring blade 604 inside the stirring tank 3.
[0030] The transverse mechanism 5 includes a disc 51, a turntable 52 rotatably mounted on the front of the disc 51, and a horizontal plate 53 fixedly mounted on one side of the disc 51. Two guide plates 54 are fixedly mounted on the front of the horizontal plate 53, and transverse rods 55 are slidably mounted inside the two guide plates 54. A drive rod 56 is connected between one end of the transverse rod 55 and the front edge of the disc 51. Both ends of the drive rod 56 are rotatably connected to the transverse rod 55 and the disc 51 respectively through a rotating shaft. A U-shaped fixed seat is fixedly mounted on the rear of the disc 51.
[0031] A rotary motor 2 for driving the turntable 2 52 to rotate is fixedly installed at the rear of the disc 51. It is located in the fixed seat and the fixed seat is fixedly connected to the fixed vertical plate 2. The other end of the horizontal moving rod 55 is fixedly connected to the side wall of the fixed plate 41. The horizontal plate 53 does not contact the fixed plate 41, and an L-shaped support rod is fixedly connected between its bottom and the support base 1.
[0032] Specifically, the rotation of turntable 52 causes the drive rod 56 to swing, which in turn causes the transverse rod 55 to reciprocate horizontally. The transverse rod 55 pushes the fixed plate 41 to reciprocate horizontally, thereby causing the stirring blade 604 to make lateral position adjustments inside the stirring tank 3.
[0033] The present invention discloses a multi-directional flour mixing device for dough processing. In use, an appropriate amount of flour and water are loaded into the mixing drum 3. The drive motor 607 drives the fixed plate 605 and its lower structure to rotate, and the mixing blade 604 rotates accordingly, thereby mixing the flour and water inside the mixing drum 3.
[0034] As the stirring blade 604 continues to stir, the upper and lower drive mechanism 4 and the transverse movement mechanism 5 operate synchronously, driving the turntable 42, which in turn drives the drive wheel 46 to move within the limit frame 47, causing the limit frame 47 to move up and down, which in turn drives the slide rod 44 and slide rod 45 to reciprocate up and down. At this time, the stirring blade 604 can move up and down inside the stirring tank 3.
[0035] As the transverse mechanism 5 is driven synchronously, the turntable 52 rotates, causing the drive rod 56 to swing and continuously push and pull the transverse rod 55 to move back and forth in the horizontal direction. At this time, the fixed plate 41 is driven to move back and forth in the horizontal direction through the transverse rod 55, which in turn drives the stirring blade 604 to move left and right inside the stirring tank 3.
[0036] Because the mixing blade 604 is modified in both the vertical and horizontal directions, the mixing blade 604 rotates, reciprocates vertically and horizontally relative to the mixing bowl 3 to form a multi-dimensional composite mixing trajectory, thereby performing multi-directional mixing treatment inside the mixing bowl 3, achieving three-dimensional kneading without dead angles, effectively avoiding dry powder residue inside the mixing bowl 3, and improving the forming quality and taste of the dough.
[0037] After the mixing operation is completed, first rotate the adjusting rod 604 to move the position of the limiting plate 610 downward, so that the bottom of the two mixing blades 604 is not restricted, and the mixing blades 604 can move to the highest position inside the mixing tank 3. Then, move the mixing tank 3 downward so that the mixing blades 604 can be removed from the mixing tank 3. When the mixing blades 604 move upward, they will fold downward due to the rotation of the shaft. The distance between the two mixing blades 604 will decrease, and their edges will generate local shear force with the dough, actively cutting off the gluten strands that are stuck together, effectively avoiding large-area adhesion between the dough and the mixing blades 604 and the mixing rod 601.
[0038] The above description is merely an example and illustration of the structure of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described, or use similar methods to replace them, as long as they do not deviate from the structure of the invention or exceed the scope defined in the claims, all of which should fall within the protection scope of the present invention.
