Description

Technical Field

[0001] This invention belongs to the field of bread processing technology, and specifically relates to a continuous dough kneading structure for bread processing. Background Technology

[0002] Existing dough kneading equipment for bread processing is mainly divided into fixed bowl kneading machines and dough hook kneading machines, but both types of equipment have significant drawbacks: Traditional dough mixers typically have their mixers rigidly connected to the motor shaft, requiring tools like wrenches for disassembly, which is cumbersome and time-consuming. This makes them unsuitable for switching between different mixers for various dough types, reducing production efficiency. Furthermore, the kneading bowl usually uses a lifting support, which can cause the bowl to wobble and shift due to the dough's reaction force during kneading, affecting the uniformity of the kneading process. Additionally, the bowl's lifting and fixing methods are limited, making it difficult to adapt to kneading bowls of different heights, resulting in poor compatibility. Therefore, we propose a continuous dough kneading structure for bread processing. Summary of the Invention

[0003] To address the problems mentioned in the background art regarding the inconvenience of replacing the mixer and the insufficient stability of the kneading bowl in dough kneading equipment for bread processing, this invention provides a continuous dough kneading structure for bread processing.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a continuous dough kneading structure for bread processing, comprising a base, a supporting shell, and a kneading bowl. The supporting shell is fixedly disposed at one end of the base. A lifting bracket is disposed at one end of the supporting shell near the base. The kneading bowl is detachably engaged at one end of the lifting bracket away from the supporting shell. A retaining ring is fixedly disposed on the outer wall of the kneading bowl. A retaining block is fixedly connected to both sides of the retaining ring. A positioning pin is disposed inside the lifting bracket at the position corresponding to the retaining block. A linkage turntable is installed below the top of the support housing. A connecting plate is fixedly connected below the linkage turntable. A docking plate is detachably connected below the connecting plate. A positioning screw is passed through the interior of both the connecting plate and the docking plate. Fixing plates are fixedly connected to both sides of the outer wall of the connecting plate. A limit block is movably installed inside the lower part of the fixing plate.

[0005] As a preferred embodiment of the continuous dough kneading structure for bread processing of the present invention, the lifting bracket is fixedly connected to both sides of one end facing the supporting housing, one of the linkage blocks is fixedly provided with a nut ring and a threaded screw is passed through the nut ring, and the other linkage block is provided with a limiting slide rod.

[0006] In a preferred embodiment of the continuous dough kneading structure for bread processing according to the present invention, one end of the threaded screw is connected to a transmission motor, and the limiting slide rod is arranged parallel to the threaded screw.

[0007] In a preferred embodiment of the continuous dough kneading structure for bread processing according to the present invention, a drive motor is fixedly connected to the upper end of the linkage turntable.

[0008] In a preferred embodiment of the continuous dough kneading structure for bread processing according to the present invention, a gear groove is provided in the middle of the upper end face of the docking plate, and a docking gear is fixedly connected to the lower end face of the connecting plate at the position corresponding to the gear groove.

[0009] In a preferred embodiment of the continuous dough kneading structure for bread processing according to the present invention, a nut is fitted on the positioning screw to fasten the connecting disc and the docking disc.

[0010] In a preferred embodiment of the continuous dough kneading structure for bread processing according to the present invention, a magnetic absorbing sheet is provided at the connection between the fixing plate and the limiting block. The magnetic absorbing sheet is a permanent magnet sheet, and the limiting block and the magnetic absorbing sheet are magnetically attracted to each other.

[0011] In a preferred embodiment of the continuous dough kneading structure for bread processing according to the present invention, a fixed plate is fixedly connected below the receiving plate, and a stirrer is fixedly installed below the fixed plate.

[0012] As a preferred embodiment of the continuous dough kneading structure for bread processing according to the present invention, the mixer is any one of spiral, mesh, or hook type.

[0013] As a preferred embodiment of the continuous dough kneading structure for bread processing according to the present invention, the lifting bracket is an arc-shaped bracket, and the kneading bowl is placed with its opening facing upward in the arc-shaped groove of the lifting bracket.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This application features a quick-change mixer that is adaptable to multiple processes. The connecting plate and the docking plate engage with a gear-gear groove to achieve circumferential positioning, while the positioning screw-nut fastening achieves axial fixation. Combined with the secondary positioning of the "limiting block-magnetic plate", the mixer can be changed quickly without tools. It is compatible with mixers of different shapes and materials, such as spiral, mesh, and hook, to meet the kneading needs of various doughs, such as hard mixers for high-gluten dough and flexible mixers for low-gluten dough, thus improving production flexibility.

[0015] The kneading bowl of this application is stable and adjustable with strong compatibility. The kneading bowl is fixed by mechanical locking of the locking block and positioning pin, and is electrically adjusted by the threaded screw and limit slide of the lifting bracket. This ensures that the kneading bowl does not shift during the kneading process and can be adapted to kneading bowls of different heights, greatly improving compatibility. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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. Embodiment 1 like Figures 1-7 As shown; A continuous dough kneading structure for bread processing includes a base 1, a support shell 2, and a kneading bowl 4. The support shell 2 is fixedly installed at one end of the base 1. A lifting bracket 3 is installed at the end of the support shell 2 near the base 1. The kneading bowl 4 is detachably engaged at the end of the lifting bracket 3 away from the support shell 2. A retaining ring 401 is fixedly installed on the outer wall of the kneading bowl 4. A retaining block 402 is fixedly connected to both sides of the retaining ring 401. A positioning pin 301 is inserted in the lifting bracket 3 at the position corresponding to the retaining block 402. The kneading bowl 4 can be quickly assembled and disassembled by engaging the retaining ring 401 fixed on the outer wall and the retaining blocks 402 on both sides with the lifting bracket 3 and fixing it with the positioning pin 301. A linkage turntable 5 is installed below the top of the support shell 2. A connecting plate 7 is fixedly connected below the linkage turntable 5. A docking plate 8 is detachably connected below the connecting plate 7. A positioning screw 701 is installed inside both the connecting plate 7 and the docking plate 8. Fixing plates 702 are fixedly connected to both sides of the outer wall of the connecting plate 7. A limiting block 703 is movably installed inside the lower part of the fixing plate 702. The positioning screw 701 passes through the connecting plate 7 and the docking plate 8 and is fastened by the nut outside the nut ring 9, forming a double locking of "gear meshing + screw fastening". At the same time, the limiting block 703 is attracted from below by the magnetic suction plate 704 to limit the docking plate 8, so as to prevent the docking plate 8 from being displaced or loosened by torque during the stirring process.

[0019] In an optional embodiment, the lifting bracket 3 is fixedly connected to both sides of one end facing the support housing 2 with linkage blocks 302. One linkage block 302 is fixedly provided with a nut ring 9 and a threaded screw 901 is passed through the nut ring 9. The other linkage block 302 is provided with a limiting slide rod 903.

[0020] In this implementation scheme, the rotational motion of the transmission motor 902 is converted into the linear lifting motion of the lifting bracket 3 by the coordinated use of the linkage block 302, the nut ring 9, the threaded screw 901 and the limit slide rod 903, thereby ensuring the stability and verticality of the lifting bracket 3 during the lifting process and preventing it from tilting or swaying.

[0021] In an optional embodiment, one end of the threaded screw 901 is connected to a transmission motor 902, and the limiting slide bar 903 is arranged parallel to the threaded screw 901.

[0022] In this implementation scheme: the transmission motor 902 provides rotational power to the threaded screw 901, thereby realizing the automatic lifting of the lifting bracket 3, replacing the traditional manual handling, greatly reducing the labor intensity of operators, and improving the efficiency of continuous processing. The limit slide bar 903 is set parallel to the threaded screw 901, further optimizing the force structure.

[0023] In an optional embodiment, the upper end of the linkage turntable 5 is fixedly connected to the drive motor 6.

[0024] In this implementation scheme: the drive motor 6 is fixedly installed at the upper end of the linkage turntable 5. This layout allows the cable of the drive motor 6 to be led out from above, which not only makes the wiring neater, but also avoids interference between the cable and the moving parts below, thus improving the safety and reliability of the equipment.

[0025] In an optional embodiment, a gear groove 803 is provided in the middle of the upper end face of the mating disc 8, and a mating gear 705 is fixedly connected to the lower end face of the connecting disc 7 at the position corresponding to the gear groove 803.

[0026] In this implementation scheme, the meshing design of the connecting gear 705 and the gear groove 803 enables rapid docking and precise positioning of the connecting disc 7 and the docking disc 8. This mechanical gear meshing method has high torsional strength, which can maintain a stable connection under the high load conditions of kneading dough and prevent the docking disc 8 from deflecting or falling off.

[0027] In an optional embodiment, a nut is fitted onto the positioning screw 701 to secure the connecting disc 7 and the mating disc 8.

[0028] In this implementation scheme: the positioning screw 701 and the nut it sleeves constitute a fastening mechanism for locking the connecting disc 7 and the mating disc 8. Compared with traditional snap-fit ​​or pin fasteners, screw fastening has extremely high connection rigidity and stability, and can effectively resist the axial and radial forces generated during the kneading process.

[0029] In an optional embodiment, a magnetic absorbing piece 704 is provided at the connection between the fixing plate 702 and the limiting block 703. The magnetic absorbing piece 704 is a permanent magnet piece, and the limiting block 703 and the magnetic absorbing piece 704 are magnetically attracted to each other.

[0030] In this implementation scheme: the limiting block 703 is magnetically attracted by a permanent magnet, thereby achieving secondary positioning of the docking plate 8. When the limiting block 703 is pushed in and attracted to the magnetic plate 704, it can firmly support the docking plate 8 from the bottom, preventing it from tilting or shifting when subjected to large torque.

[0031] In an optional embodiment, a fixed plate 801 is fixedly connected to the lower part of the docking plate 8, and a stirrer 802 is fixedly disposed below the fixed plate 801.

[0032] In this implementation scheme: a fixed plate 801 and a mixer 802 are connected sequentially below the docking plate 8. This modular integrated connection structure ensures the effective transmission of mixing force, enabling the mixer 802 to stably apply shear and extrusion forces to the dough.

[0033] In an alternative embodiment, the stirrer 802 is any one of spiral, mesh, or hook type.

[0034] In this implementation plan, the mixer 802 is designed as a spiral, mesh, or hook type, greatly enhancing the versatility of the equipment. The spiral type is suitable for kneading and degassing dough, the hook type is suitable for heavy oil dough or stretching and folding dough, and the mesh type is suitable for initial mixing of dough or whipping butter. Users can quickly change the appropriate mixing head according to different ingredients and process requirements, making it a multi-purpose machine.

[0035] In an optional embodiment, the lifting bracket 3 is an arc-shaped bracket, and the kneading basin 4 is placed with its opening facing upward in the arc-shaped groove of the lifting bracket 3.

[0036] In this implementation scheme: the lifting bracket 3 is designed as an arc-shaped bracket, which matches the arc-shaped bottom of the kneading basin 4. This contoured arc design increases the contact area between the lifting bracket 3 and the kneading basin 4, and can evenly distribute the pressure when the kneading basin 4 is raised, lowered, or subjected to kneading force, preventing the kneading basin 4 from slipping or deforming at the bottom.

[0037] Working principle: Installation and Height Adjustment: Place the kneading bowl 4 on the bearing end of the lifting bracket 3, aligning the locking block 402 on the retaining ring 401 on the outer wall of the kneading bowl 4 with the positioning channel inside the lifting bracket 3. Then, insert the positioning pin 301 into the lifting bracket 3 and lock the locking block 402. Through the mechanical locking structure of "pin-locking block 402", the kneading bowl 4 is quickly fixed on the lifting bracket 3, ensuring that the kneading bowl 4 does not shift during kneading. Start the transmission motor 902, which drives the threaded screw 901 to rotate. The rotation of the threaded screw 901 is converted into the linear movement of the lifting bracket 3 along the limiting slide bar 903. At the same time, the limiting slide bar 903 guides the lifting bracket 3. When the lifting bracket 3 drives the kneading bowl 4 to a suitable height, such as when the gap matches the mixer 802, the transmission motor 902 stops, completing the height adjustment of the kneading bowl 4 and ensuring that the dough kneading space is precise and controllable. Installation and reinforcement of the mixing assembly: The mixer 802 is installed below the connecting plate 7 via the fixing plate 801 and the docking plate 8 in sequence, so that the docking gear 705 meshes with the gear groove 803. The gear meshing achieves circumferential positioning and prevents the mixer 802 from slipping during operation. Tighten the nut outside the positioning screw 701. Through the axial preload of the "screw-nut", the connecting plate 7 and the docking plate 8 are fastened into a whole, completing the installation of the mixer 802. Then push the limiting block 703 below the fixing plate 702 inward so that the limiting block 703 is engaged with the edge groove of the docking plate 8. At this time, the magnetic suction plate 704 above the limiting block 703 is attracted to the limiting block 703. The magnetic suction plate 704 provides a continuous suction force, forming a secondary limit on the docking plate 8 from below, preventing the connection from loosening due to vibration when the mixer 802 is working, and improving the structural stability.

[0038] Dough kneading process: Start the drive motor 6. The drive motor 6 drives the connecting plate 7, docking plate 8, fixed plate 801 and mixer 802 to rotate synchronously through the linkage turntable 5. The mixer 802 applies shearing and kneading force to the dough in the kneading bowl 4 to realize the kneading process of the dough. After kneading, the kneading bowl 4 can be lowered and taken out through the height adjustment function of the lifting bracket 3, or a mixer 802 of different specifications can be replaced to adapt to different dough processes, such as high-gluten dough requires a high-torque mixer 802, and low-gluten dough requires a gentle mixer 802. Replacement of the mixing assembly: When disassembling the mixing assembly, unscrew the nut on the outside of the positioning screw 701 to release the fastening of the positioning screw 701 to the connecting plate 7 and the mating plate 8. Then pull the connecting plate 7 upward to separate the mating gear 705 at the lower end of the connecting plate 7 from the gear groove 803 at the upper end of the mating plate 8. The mating plate 8 and the fixing plate 801 and the agitator 802 below it can then be removed. The agitator 802 is now disassembled. A new mixing assembly can then be installed as needed.

[0039] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
