[0001] This utility model relates to the field of food processing equipment technology, and in particular to a dough mixer. Background Technology

[0002] With the rapid development of the food processing industry, the application of automated and mechanized equipment is becoming more and more widespread. As an important piece of equipment, dough mixers have received widespread attention because they can significantly improve production efficiency and reduce labor costs.

[0003] Specifically, current dough mixers on the market, such as the one disclosed in utility model patent application number 202120881568.4, while achieving automation of the dough mixing process to some extent, still have design shortcomings. The dough mixer structure described in the existing patent mainly consists of a frame, a mixing bowl, a mixing component, and a drive mechanism. The mixing bowl is rotatably mounted on the frame, and the mixing component is rotatably mounted on the frame and driven by the drive mechanism to rotate within the mixing bowl to complete the dough mixing task. However, in actual use, the following problems still exist:

[0004] First, because the frame is designed as an integral structure, when users need to disassemble and reassemble the mixing tank and mixing components for cleaning and maintenance, the mixing components and mixing tank are prone to interference during the disassembly and reassembly process, resulting in a cumbersome and time-consuming disassembly and reassembly process.

[0005] Secondly, the driving components are set for the mixing components and the mixing tank respectively, which not only increases the production cost of the equipment, but also makes the overall structure of the equipment more complex.

[0006] Therefore, how to provide a dough mixer that allows for easy disassembly and assembly of mixing components and mixing bowls, reduces production costs, and improves the user experience is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0050] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0051] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0052] See Figure 1 This application provides a dough mixer, comprising a lower body 1, on which a dough mixing bowl 3 is rotatably mounted. Ingredients such as flour to be mixed are placed into the dough mixing bowl 3. The lower body 1 provides support for the dough mixing bowl 3 and can drive the dough mixing bowl 3 to rotate, achieving the required kneading state in a shorter time, thus improving kneading efficiency and effect. An upper body 2 is rotatably connected at its lower end to the upper end of the lower body 1. The upper body 2 rotates between a closed position and an open position; that is, the upper body 2 can rotate around the connection point with the lower body 1. When the upper body 2 rotates towards the lower body 1 until the two are approximately in contact, the upper body 2 is in the closed position. Figure 1 As shown, when the upper body 2 rotates away from the lower body 1, the upper body 2 is in the open position, as indicated. Figure 4 As shown in the diagram; a stirring element 4 is rotatably mounted on the upper body 2, and the stirring element 4 is used to stir the ingredients in the dough mixing bucket 3; when the upper body 2 rotates to the closed position, the driving mechanism drives the dough mixing bucket 3 to rotate on the lower body 1, and drives the stirring element 4 to rotate inside the dough mixing bucket 3.

[0053] In other words, the dough mixer of this application has a split structure, in which one side of the upper body 2 is rotatably connected to the lower body 1. The specific rotatable connection structure can be a rotating shaft, a pin shaft, a hinge, etc., which is not limited here. This allows the upper body 2 to rotate up and down relative to the lower body 1. In the closed position, the upper body 2 and the lower body 1 are tightly connected. In the open position, the upper body 2 is away from the lower body 1, providing more operating space for removing the dough mixing bowl 3. When the upper body 2 rotates to the closed position, the drive mechanism drives the dough mixing bowl 3 to rotate on the lower body 1 and drives the mixing component 4 to rotate inside the dough mixing bowl 3. As a result, the flour, water and other raw materials are stirred and kneaded by the mixing component 4 inside the dough mixing bowl 3, gradually forming dough.

[0054] The dough mixer provided by this utility model has a split structure, allowing the upper body to rotate relative to the lower body. That is, the upper body can rotate between a closed position and an open position. When the dough is ready to be removed, the upper body can be rotated to the open position, providing more operating space for removing the dough bowl, which is convenient for users and improves the user experience. When the upper body rotates to the closed position, the drive mechanism can simultaneously drive the dough bowl to rotate on the lower body and the mixing component to rotate inside the dough bowl. This reduces the number of drive components compared to the prior art, thereby reducing manufacturing costs.

[0055] See Figure 2 The driving mechanism includes a driving component 5; a transmission shaft 6, which the driving component 5 drives the transmission shaft 6 to rotate; a first transmission assembly 7, the input end of which is connected to the transmission shaft 6 via a clutch assembly 8, which can realize the connection or disconnection of the first transmission assembly 7 and the transmission shaft 6; the output end of the first transmission assembly is detachably connected to the stirring component 4 to drive the stirring component 4 to rotate; the clutch assembly 8 includes an engaged state and a disengaged state. When the upper body 2 rotates to the closed position, the clutch assembly 8 is in the engaged state, and the first transmission assembly 7 is connected to the transmission shaft 6; when the upper body 2 rotates to the open position, the clutch assembly 8 is in the disengaged state, and the first transmission assembly 7 is disconnected from the transmission shaft 6.

[0056] Specifically, the drive component 5 can be a drive motor, which is installed inside the lower body 1. Installing the drive component 5 inside the lower body 1 makes the structure more compact, improves space utilization, and can lower the center of gravity of the dough mixer, thereby improving the overall stability of the dough mixer. The transmission shaft 6 is rotatably installed inside the lower body 1 and is connected to the output shaft of the drive component 5. The upper end of the transmission shaft 6 extends upward to near the interior of the upper body 2.

[0057] The first transmission assembly 7 is installed in the cavity of the upper body 2. Its main function is to transmit the rotational power of the transmission shaft 6 to the mixing component 4, so that the transmission shaft 6 drives the mixing component 4 to rotate and complete the kneading. The input end of the first transmission assembly 7 is connected to the top end of the transmission shaft 6 through the clutch assembly 8.

[0058] See Figure 3 When the upper body 2 and the lower body 1 are combined (i.e. when the upper body 2 rotates to the closed position), the clutch assembly 8 is engaged, so that the first transmission assembly 7 can receive the rotational power from the transmission shaft 6, which drives the mixing component 4 to start rotating in the dough mixing bucket 3, thereby completing the dough mixing work.

[0059] Furthermore, when the user flips the upper body 2 upwards (i.e., when the upper body 2 is rotated upwards to the open position), the mixing component 4 will also move accordingly. At this time, the clutch assembly 8 is in the disengaged state, realizing the disconnection of power between the first transmission assembly 7 and the transmission shaft 6. Thus, when the user flips and opens the upper body 2 to observe the dough's kneading state, or when the dough needs to be removed after kneading, the clutch assembly 8 changes from the engaged state to the disengaged state as the upper body 2 is flipped upwards. That is, the clutch assembly 8 disengages along with the upper body 2, the connection between the first transmission assembly 7 and the transmission shaft 6 is broken, and the mixing component 4 connected to the first transmission assembly 7 stops rotating. This avoids the safety hazard caused by the rotation of the mixing component 4 when the user observes or removes the dough, and also saves the trouble of having to perform an additional operation to stop the rotation of the mixing component 4 when flipping and opening the upper body 2.

[0060] Specifically, the dough mixing bowl 3 is detachably connected to the lower body 1. Thus, when the upper body 2 is flipped open, the entire dough mixing bowl 3 can be disassembled from the lower body 1 for weighing or cleaning, improving the convenience of use for users.

[0061] Specifically, an input gear is provided on the transmission shaft 6, and an output gear is provided on the output end of the drive component 5. The input gear and the output gear mesh with each other.

[0062] In other words, when the drive unit 5 starts working, its output gear will begin to rotate. Since the input gear and the output gear are meshed, the rotation of the output gear will drive the input gear and the transmission shaft 6 connected to it to rotate together. Of course, in addition to the gear meshing transmission type, other transmission structures such as gear racks and pinions and couplings can also be used, and there are no restrictions here.

[0063] See Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 9 The clutch assembly 8 includes a chuck 81 and a chuck head 83; wherein, one of the chuck 81 and the chuck head 83 is connected to the drive shaft 6, and the end face of the chuck 81 is provided with a plurality of first protrusions 82 in a circumferential direction; the other of the chuck 81 and the chuck head 83 is connected to the input end of the first transmission assembly 7, and the end face of the chuck head 83 is provided with a plurality of second protrusions 84 in a circumferential direction, and the second protrusions 84 are adapted to the first protrusions 82.

[0064] In other words, the clutch assembly 8 uses a chuck 81 and a chuck head 83 connected by a first protrusion 82 and a second protrusion 84, which avoids complex transmission mechanisms and additional connecting parts, making the overall structure of the clutch assembly 8 simpler and more compact. The cooperative design between the first protrusion 82 and the second protrusion 84 enables the chuck 81 and the chuck head 83 to form a stable mechanical lock when connected.

[0065] See Figure 3 and Figure 5 The first transmission assembly 7 includes a first output shaft 71, which is rotatably connected to the first mounting cavity 21 of the upper body 2. The bottom of the first output shaft 71 is connected to the clamp head 83, and the top is provided with a first transmission wheel 72. The second output shaft 73 is rotatably connected to the second mounting cavity 22 of the upper body 2. The top of the second output shaft 73 is provided with a second transmission wheel 74. The first transmission wheel 72 and the second transmission wheel 74 are connected in a transmission manner. The bottom of the second output shaft 73 is detachably connected to the stirring component 4.

[0066] In other words, the first output shaft 71 is rotatably connected to the first mounting cavity 21 of the upper body 2, its bottom is connected to the chuck 83 of the clutch assembly 8, and the first transmission wheel 72 is provided on the top of the first output shaft 71.

[0067] The second output shaft 73 is rotatably connected to the second mounting cavity 22 of the upper body 2, forming a certain spatial arrangement with the first output shaft 71 to avoid mutual interference. A second transmission wheel 74 is installed at the top of the second output shaft 73. Specifically, both the first transmission wheel 72 and the second transmission wheel 74 are pulleys, and the second transmission wheel 74 and the first transmission wheel 72 are connected by a first synchronous belt to ensure continuous power transmission. The bottom of the second output shaft 73 is designed with an interface for detachable connection to the stirring component 4, allowing the user to replace or adjust the stirring component 4 as needed. Simultaneously, the stirring component 4 can be disassembled for cleaning, improving ease of use.

[0068] Specifically, the chuck 81 is connected to the drive shaft 6, and the chuck head 83 is connected to the first output shaft 71. When the upper body 2 rotates downward relative to the lower body 1 and merges, the chuck head 83 moves together with the first output shaft 71, so that the second protrusion 84 gradually approaches and inserts between the adjacent first protrusion 82, thereby ensuring that the power is smoothly transmitted from the drive shaft 6 to the first output shaft 71 through the chuck 81, the contact surface between the first protrusion 82 and the second protrusion 84, and the chuck head 83. The drive component 5 drives the first output shaft 71 to rotate, which in turn drives the mixing component 4 to rotate to knead the dough.

[0069] When the upper body 2 rotates upward and separates from the lower body 1, as the upper body 2 rises, the distance between the chuck 83 and the chuck 81 gradually increases, and the second protrusion 84 and the first protrusion 82 gradually separate until they are completely detached, thereby cutting off the transmission of power from the drive shaft 6 to the first output shaft 71 and stopping the kneading action of the mixing component 4.

[0070] Specifically, both the first protrusion and the second protrusion are trapezoidal blocks. The side where the first protrusion 82 and the second protrusion 84 meet is vertically oriented. It can be understood that the contact surface of the first protrusion 82 and the second protrusion 84 is perpendicular to the power transmission direction, thereby increasing the contact area between them, thus improving the friction and making the power transmission more stable and reliable.

[0071] The first protrusion 82 and the second protrusion 84 are inclined on the side away from the contact surface. The top of the second protrusion 84 is rounded. By using the guiding effect of the inclined surface and the arc surface, it is easier for the second protrusion 84 to be inserted between the adjacent first protrusion 82, and when the chuck 83 is disengaged from the chuck 81, it is easier for the second protrusion 84 to separate from the first protrusion 82.

[0072] Reference Figure 6 The chuck 83 includes a first cylinder 831 and a second cylinder 832 arranged coaxially. The first cylinder 831 has a connecting hole 833 axially arranged, and the first output shaft 71 has a connecting end 711 that mates with the connecting hole 833. The chuck 83 is connected to the first output shaft 71 by inserting the connecting end 711 into the connecting hole 833. The structure is simple and the connection is reliable. Specifically, the connecting hole 833 can be a regular hexagonal hole, and the connecting end 711 can be a regular hexagonal prism, thereby ensuring a stable connection between the chuck 83 and the first output shaft 71 and preventing relative rotation. In addition, the connection method between the connecting end 711 and the connecting hole 833 can also be a key or pin connection, etc.

[0073] See Figure 4-6 and Figure 8-9 The second cylinder 832 is axially provided with a mounting hole 834 that connects to the connecting hole 833. The diameter of the mounting hole 834 is larger than the diameter of the connecting hole 833. The first output shaft 71 is provided with a connecting end 711 that mates with the connecting hole 833. A limiting plate 835 that connects to the bottom end of the connecting end 711 is provided inside the mounting hole 834.

[0074] Specifically, the second cylinder 832 has an axial mounting hole 834, which is connected to the connecting hole 833. However, the mounting hole 834 is larger than the connecting hole 833 to accommodate the bottom end of the connecting end 711 and the limiting plate 835. The limiting plate 835 is installed in the mounting hole 834 and connected to the bottom end of the connecting end 711. The outer diameter of the limiting plate 835 is larger than the diameter of the connecting hole 833, thereby preventing the chuck 83 from falling off the first output shaft 71 and limiting the axial movement stroke of the chuck 83.

[0075] The inner wall of the first mounting cavity 21 is provided with a number of limiting grooves 211 around the circumference. The outer peripheral surface of the top end of the jack 83 is provided with ear plates 836 at intervals. The limiting grooves 211 allow the ear plates 836 to pass vertically. The outer peripheral surface of the first output shaft 71 located above the limiting grooves 211 is fitted with an elastic element 712.

[0076] Specifically, when the upper body 2 rotates upward relative to the lower body 1, the chuck 83 separates from the chuck 81. Under the elastic force of the elastic element 712, the chuck 83 moves downward relative to the connecting end 711, so that the ear plate 836 is located in the limiting groove 211, causing the first output shaft 71 to stop rotating, thereby limiting the rotation of the mixing element 4. This improves the timeliness and reliability of stopping and locking the mixing element 4 when the clutch assembly 8 is in the disengaged state, facilitates the disassembly and assembly of the mixing element and the dough mixing bowl, and through the setting of the limiting plate 835, when the elastic element 712 returns to its original position, the limiting plate 835 ensures that the ear plate 836 of the chuck 83 is always kept in the limiting groove 211. The elastic element 712 can be selected as a spring.

[0077] Specifically, the upper opening of the limiting groove 211 is chamfered to guide the ear plate 836 through the limiting groove 211.

[0078] When the upper body 2 rotates downward relative to the lower body 1, the chuck head 83 moves together with the first output shaft 71, and the second protrusion 84 inserts between the adjacent first protrusion 82. As the first protrusion 82 and the second protrusion 84 abut, the chuck 81 pushes the chuck head 83 upward, thereby overcoming the elastic force of the elastic element 712. The ear plate 836 will disengage from the limiting groove 211 as the chuck head 83 moves upward. When the chuck 81 and the chuck head 83 abut in place and the clutch assembly 8 is in the engaged state, the ear plate 836 completely disengages from the limiting groove 211, releasing the lock on the first output shaft 71. At this time, the first output shaft 71 and the stirring element 4 can rotate under the drive of the transmission shaft 6.

[0079] Reference Figure 2 The drive mechanism also includes a second transmission assembly 9, which is mounted on the lower body 1. Its main function is to transmit the rotational power of the transmission shaft 6 to the dough mixing bucket 3. The input end of the second transmission assembly 9 is connected to the bottom end of the transmission shaft 6, while the output end is detachably connected to the dough mixing bucket 3, allowing users to easily disassemble and assemble the dough mixing bucket 3 when not in use or during maintenance.

[0080] Specifically, the second transmission assembly 9 includes: a third output shaft, rotatably connected to the lower body 1, a third transmission wheel 91 fixedly mounted on the third output shaft, and a fourth transmission wheel 61 fixedly mounted at the bottom of the transmission shaft 6. Specifically, the third transmission wheel 91 and the fourth transmission wheel 61 can be pulleys, and the third transmission wheel 91 and the fourth transmission wheel 61 are connected by a second synchronous belt. A turntable 92 is mounted at the top of the third output shaft, and the dough mixing drum 3 is detachably connected to the turntable 92.

[0081] Specifically, when the drive shaft 6 rotates, the fourth drive wheel 61 rotates accordingly, transmitting power to the third drive wheel 91 via the second synchronous belt. Upon receiving power, the third drive wheel 91 drives the third output shaft to rotate. The rotation of the third output shaft further drives the turntable 92 to rotate, thereby driving the mixing bowl 3 to perform mixing operations. Thus, when kneading dough using the dough mixer of this embodiment, in addition to the kneading action performed by the mixing element 4, the mixing bowl 3 can also rotate simultaneously, reducing the dough's sticking to the wall of the mixing bowl 3 during kneading, resulting in better kneading performance.

[0082] The dough mixer in this embodiment also includes a limiting component, which is used to constrain the upward rotation of the upper body 2 relative to the lower body 1. The limiting component includes an arc-shaped plate 111 with an arc-shaped groove 112, one end of which is connected to the upper body 2; and a fixing post 113, which is fixed to the lower body 1 and located within the arc-shaped groove 112.

[0083] Specifically, when the upper body 2 rotates upward relative to the lower body 1, the arc-shaped plate 111 rotates accordingly, causing the arc-shaped groove 112 to slide on the fixed post 113. Therefore, when the arc-shaped groove 112 slides to its end, it will be blocked by the fixed post 113, thus limiting the rotation range of the upper body 2. Furthermore, when the upper body 2 flips up and down, it is restricted by the arc-shaped groove 112, ensuring reliable operation, reducing swaying during flipping, and providing a better user experience.

[0084] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0085] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
