[0021] The taste, flavor, and texture of pasta products largely depend on the quality of the dough, also known as dough. The main components of dough are flour and water; some pasta products also include oil, eggs, and other ingredients. After mixing these ingredients, the dough needs to be kneaded or rolled to obtain the desired consistency. Traditionally, the dough is mixed and kneaded manually, which is inefficient and labor-intensive.

[0022] To reduce labor costs, dough kneading machines have emerged on the market, using mechanical structures to knead and mix dough. Current dough kneading machines mainly consist of a container and a mixing head. The corresponding ingredients are added to the container, and a power device drives the mixing head to rotate, thus mixing the materials in the container to form the dough. This kneading method is singular, and the mechanical force is limited to the rotating area, failing to achieve comprehensive and three-dimensional kneading. The kneading effect is uneven, easily leading to localized over-kneading and under-kneading, resulting in poor mixing of the dough and unsatisfactory protein network formation. This is particularly problematic for high-gluten dough or high-moisture dough requiring high-intensity kneading, significantly prolonging processing time and resulting in a low yield rate. Therefore, there is an urgent need for a dough kneading device that can mimic the multi-dimensional and comprehensive kneading action of human labor, while also possessing high processing efficiency and high kneading uniformity.

[0023] The following is for reference only. Figure 1 To be continued Figure 5 This invention describes a kneading device for dough, which is capable of kneading in different dimensions with different actions, resulting in high kneading efficiency and comprehensive and uniform kneading effect.

[0024] Reference Figures 1 to 5 A kneading device for dough according to an embodiment of the present invention includes: The mixing assembly 100 includes a base 110, a mixing drive module 120, and a mixing tank 130. The mixing drive module 120 is connected to the base 110, and the mixing tank 130 is connected to the mixing drive module 120. The dough kneading assembly 200 includes a lifting drive module 210, a cover plate 220, a dough kneading motor 230, and a dough kneading rod 240. The lifting drive module 210 is connected to the base 110, and the cover plate 220 is connected to the lifting drive module 210. The cover plate 220 is located above the mixing tank 130 and is used to close the opening of the mixing tank 130. The dough kneading motor 230 is connected to the cover plate 220, and the dough kneading rod 240 is connected to the dough kneading motor 230. The dough kneading shaft of the dough kneading rod 240 and the mixing shaft of the mixing tank 130 are both perpendicular to the horizontal plane. The dough kneading rod 240 is also rotatably connected to the cover plate 220 through a rotary bearing. The dough-kneading assembly 300 includes a dough-kneading motor 310, a drive wheel 320, a linkage arm 330, a lifting column 340, a guide sleeve 350, and a dough-kneading hammer 360. The dough-kneading motor 310 and guide sleeve 350 are both connected to a cover plate 220. The drive wheel 320 is connected to the dough-kneading motor 310 and can be configured as a cam. The middle part of the linkage arm 330 is rotatably connected to the cover plate 220 via a linkage shaft 331. The linkage shaft 331 of the linkage arm 330 is parallel to the horizontal plane. The linkage arm 330 has drive elongated holes 332 and driven elongated holes 333 located on opposite sides of the linkage shaft 331. The drive wheel 320 has a drive shaft 321 passing through the drive elongated hole 332 and parallel to the linkage shaft 331 at its eccentric position. The lifting column 340 has a driven shaft 341 passing through the driven elongated hole 333 and parallel to the linkage shaft 331. Hammer 360 is connected to the bottom of lifting column 340. The horizontal projection of kneading hammer 360 and kneading rod 240 are both located in the horizontal projection of mixing tank 130. Kneading rod 240 and kneading hammer 360 are used to process the raw materials in mixing tank 130. Guide sleeve 350 is connected to cover plate 220. Lifting column 340 passes through guide sleeve 350. The axis of guide sleeve 350 is perpendicular to the horizontal plane. Guide sleeve 350 is used to restrict lifting column 340 to only achieve linear lifting and lowering movement in a direction perpendicular to the horizontal plane. Kneading rod 240 and kneading hammer 360 cooperate in different dimensions with different movement forms to achieve kneading and mixing of dough. The kneading trajectory of kneading rod 240 and kneading trajectory of kneading hammer 360 are adjacent to each other, which can avoid mutual interference between kneading rod 240 and kneading hammer 360 and improve the stability of the structure.

[0025] The kneading device of this utility model embodiment mainly includes the following two sets of actions: When opening and closing the lid, the lifting drive module 210 drives the cover plate 220 and its connected structure to rise to open the mixing tank 130, allowing operators to feed or remove materials from the mixing tank 130.

[0026] During the lid-closing process, the dough in the mixing tank 130 is formed. The mixing drive module 120 drives the mixing tank 130 to rotate, so that the dough in different areas of the mixing tank 130 reaches the kneading rod 240 and the kneading hammer 360 at different times. The kneading motor 230 drives the kneading rod 240 to rotate to stir and knead the dough in its area. The kneading motor 310 drives the drive wheel 320 to rotate. When the drive shaft 321 rotates to a position above the rotation axis of the drive wheel 320, the drive shaft 321... The drive arm 330 rotates through the active elongated hole 332. The end of the drive arm 330 near the drive shaft 321 rises, and the other end of the drive arm 330 away from the drive shaft 321 falls. Under the combined action of the driven elongated hole 333 and the driven shaft 341, the lifting column 340 is pressed down. The lifting column 340 drives the kneading hammer 360 to fall and squeeze the dough in the mixing tank 130. The squeezed dough rotates with the mixing tank 130 at the same time, which can form a kneading processing effect. The multi-dimensional kneading processing action in different areas is reliable.

[0027] The mixing tank 130 is rotated by the mixing drive module 120, so that the dough pieces in different areas of the mixing tank 130 can be aligned with the kneading rod 240 and the kneading hammer 360 at different times. The kneading rod 240 can wrap, stretch and shear the dough piece by rotating around the kneading axis eccentric to the mixing axis, thereby achieving kneading. The kneading hammer 360 can pound and squeeze the dough piece by lifting and lowering to achieve kneading. Thus, through the cooperation of the three sets of structures of mixing, kneading and kneading, the dough pieces in the same cavity space can be kneaded in a multi-dimensional and segmented manner. The dough pieces can be fully and effectively stretched in all directions, and the protein molecular chains can be manipulated in different dimensions. With force, comprehensive cross-linking can be achieved, accelerating the formation of a strong and uniformly distributed protein network. The dough produced by kneading is strong, uniform, and highly extensible, resulting in high-quality kneading and thorough mixing. The resulting dough has a fine internal structure, uniform pore distribution, good extensibility, and good elasticity, with high consistency and high yield. This provides a good foundation for subsequent fermentation and other processing steps. Furthermore, the simultaneous kneading and mixing of each area results in high processing efficiency and comprehensive kneading and mixing coverage, effectively shortening the kneading and mixing processing time. The dough kneading and mixing capacity is high, and the overall structure is compact and reasonable, with the movements of the 240-degree kneading rod and the 360-degree kneading hammer not interfering with each other.

[0028] The drive shaft 321 follows the rotation of the drive wheel 320, forming a circular motion trajectory perpendicular to the horizontal plane. In conjunction with the drive elongated hole 332, it drives the linkage arm 330 to swing in a plane perpendicular to the horizontal. Furthermore, it drives the driven shaft 341 to raise and lower via the driven elongated hole 333, which in turn drives the kneading hammer 360 to rise and fall via the lifting column 340. The rotation of the kneading motor 310, through the linkage arm 330 and the drive wheel 320, drives the kneading hammer 360 to achieve periodic reciprocating raising and lowering motion. This design is convenient to control. Compared to the telescopic drive of the cylinder 211, the kneading motor of this application... 310 can achieve closed-loop control through an encoder, with high positioning accuracy and low positioning and lifting delay. The kneading motor 310 drives the rotating housing to control the lifting and lowering of the kneading hammer 360. Compared with the conventional cylinder 211 telescopic drive, the motion curve formed by the kneading motor 310 driving the kneading hammer 360 in this application is smooth, which can effectively avoid sudden changes in motion state. The changes in lifting and lowering are smooth and seamless, which can effectively reduce the shaking generated during kneading and mixing. The operation is stable and reliable, which can not only reduce noise pollution, but also effectively extend the service life of the overall structure.

[0029] In addition, the motor can output a constant large torque when running at low speed, which can meet the lifting drive of high load. The motor only consumes power when it is in operation, and the standby power consumption is close to zero, which is highly efficient. In contrast, the cylinder 211 requires the continuous operation of the air compressor to replenish air, resulting in large pipeline leakage losses. This application can effectively reduce energy consumption by driving the lifting and reciprocating motion through the kneading motor 310. Moreover, the operation of the motor does not require the investment of additional equipment such as air tanks and air compressors required when the cylinder 211 is used. This not only effectively reduces the investment cost of the device, but also reduces the complexity of the device structure and the space occupied.

[0030] Understandably, the kneading rod 240 is hook-shaped and includes a first vertical rod 241, a horizontal rod 242, and a second vertical rod 243. The top end of the first vertical rod 241 is connected to the kneading motor 230, one end of the horizontal rod 242 is connected to the bottom end of the first vertical rod 241, and the other end of the horizontal rod 242 is connected to the second vertical rod 243. By kneading the dough with the narrow-section kneading rod 240, contact friction can be effectively reduced, thereby effectively reducing resistance. This not only saves energy and reduces costs but also reduces the failure rate of the kneading motor 230, resulting in high overall operational stability.

[0031] Furthermore, the hook-shaped kneading rod 240 can simulate the kneading action of a pastry chef's fingers. The hook-shaped kneading rod 240 can effectively penetrate into the interior of the dough and stretch it. The multi-dimensional extended hook-shaped kneading rod 240 can fold and roll the dough during rotation, which can further simulate the kneading action of the palm. Moreover, the second longitudinal rod 243, which bends back at the end, can generate centripetal thrust, thereby further promoting the cross-linking of protein molecular chains in the dough.

[0032] Understandably, the top of the first longitudinal bar 241 bends from bottom to top near the second longitudinal bar 243, which provides ample design space for the setting of the dough kneading motor 230. The dough kneading motor 230 can be set close to the center, thereby optimizing the gravity distribution of the structure connected to the cover plate 220 and improving the stability of the structure.

[0033] It is understood that the kneading hammer 360 includes a first pressing block 361, a vertical block 362, and a second pressing block 363. The first pressing block 361 is connected to the bottom of the lifting column 340. The upper and lower ends of the vertical block 362 are respectively connected to the second pressing block 363 and the first pressing block 361. The second pressing block 363 is located above the first pressing block 361. By hammering and kneading the dough in a gradient manner, the resistance can be effectively reduced, thereby improving the stability and reliability of the hammering and kneading action. The second pressing block 363 is located on the side of the first pressing block 361 that is close to the kneading rod 240. It can push the dough closer to the kneading rod 240, thereby increasing the contact probability between the dough and the kneading rod 240 and effectively improving the comprehensiveness of kneading and mixing.

[0034] The stepped kneading hammer 360 can differentiate the pressure distribution and dynamic impact, thereby simulating the complex mechanical effects of hand pounding. The upward-lifting second pressing block 363 can form a low-pressure buffer zone and provide room for the dough to rebound, which can reduce ineffective energy consumption and prevent the dough from over-hardening or even cracking due to excessive compression. In addition, the stepped kneading hammer 360 can form high and low frequency impacts distributed in space, which can quickly break large air bubbles in the dough while retaining small air bubbles. This is beneficial for subsequent processing such as fermentation and baking, and helps to improve the taste of the final pastry products.

[0035] Understandably, the bottom of the first pressing block 361 is provided with a guide block 364. Along the direction perpendicular to the horizontal plane, the cross-sectional area of ​​the guide block 364 gradually decreases from top to bottom. The guide block 364 can be a hemisphere with a sphere on top, an inverted frustum, or an inverted cone, etc. The guide block 364 can provide a downward cutting space for the hammering and kneading of the first pressing block 361, which can reduce the resistance from the blank during the hammering and kneading process, thereby effectively improving the stability of the hammering and kneading action, reducing unnecessary vibration, and extending service life.

[0036] It is understood that the dough-pinching assembly 300 also includes an elastic element 370, and the lifting column 340 is also provided with a limiting block 342 located below the driven shaft 341. The two ends of the elastic element 370 are respectively connected to the limiting block 342 and the cover plate 220 so that the limiting block 342 forms an upward movement trend. Preferably, the elastic element 340 can be set as a spring.

[0037] The elastic element 370, through the limiting block 342, generates a continuous upward pulling force on the lifting column 340, thus forming an adaptive buffering mechanism. This further improves the stability of the operation. When the resistance of the dough hammer 360 hitting the dough increases instantaneously, this mechanism allows for slight displacement compensation between the linkage arm 330, the drive shaft 321, and the driven shaft 341. This effectively absorbs and buffers excessive impact force, preventing the mechanism from jamming or the motor from overloading. It also improves the equipment's adaptability to dough of different hardness, protects the transmission components, extends their service life, and ensures high operational stability. It is understood that the mixing drive module 120 includes a mixing motor 121 and a mixing base 122. The mixing motor 121 is connected to the base 110, the mixing base 122 is rotatably connected to the base 110, and the mixing base 122 is also connected to the mixing motor 121. The mixing motor 121 can be configured as a geared motor. The mixing tank 130 is connected to the mixing base 122, and the mixing motor 121 can be a geared motor.

[0038] The mixing tank 130 and the mixing seat 122 can be fixedly connected or detachably connected. When it is fixedly connected, the blank is removed by manual scraping. When it is detachably connected, the line can be changed by directly replacing the mixing tank 130. The removable mixing tank 130 can be used for feeding and removing materials independently, which can effectively improve processing efficiency.

[0039] It is understood that the lifting drive module 210 includes a cylinder 211 and a lifting seat 212. The cylinder 211 is connected to the base 110, and the lifting seat 212 is connected to the cylinder 211. The cylinder 211 extends and retracts in a direction perpendicular to the horizontal plane to drive the lifting seat 212 to rise and fall. The cover plate 220 is connected to the lifting seat 212. Preferably, the base 110 may be provided with a lifting guide structure, and the lifting seat 212 is connected to the lifting guide structure to assist the lifting seat 212 in achieving stable lifting action. The lifting guide structure may be a guide slide and a guide slider slidably connected to the guide slide.

[0040] Understandably, the cover plate 220 is provided with an observation window 221, through which the internal condition of the mixing tank 130 can be observed. This not only improves the convenience of supervision but also facilitates the replenishment of materials during the kneading process. Preferably, the cover plate 220 is also movably connected to a window cover for closing the observation window 221. Under normal operating conditions, the window cover closes the observation window 221, which can prevent pollutants in the environment from entering the mixing tank 130.

[0041] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
