Technical Field
[0001] The utility model belongs to the technical field of dough mixer equipment, and in particular relates to a rolling type dough mixer. Background Art
[0002] Wheat starch is starch extracted from wheat flour. The extraction method is to add flour to the dough mixer, add 50% to 80% water, knead the flour into dough at a speed of 40 rpm, stir for about 30 minutes, and leave for 30 minutes to make the gluten swell and stick to each other, so that the starch is easy to separate. If an appropriate amount of salt is added, the quality of the gluten can be improved and its bonding can be promoted. If there is a lot of free acid in the flour, an appropriate amount of calcium hydroxide can be added to adjust its pH value. After the dough is temporarily left to stand, add 5 to 8 times of water to knead and wash, and knead and wash 3 to 4 times. The washed emulsion is starch milk, which needs to be refined and purified. The remaining material is gluten, which contains 65% to 70% water. After drying, the protein content is about 75% to 85%, which can be eaten or used as a raw material for making oil gluten.
[0003] When kneading wheat flour into dough, a dough mixer is often used. However, during the dough kneading process, the range of the stirring shaft is limited, so the stirring shaft cannot fully stir the entire range of the dough barrel, causing some flour to be unevenly stressed. Not only does it take a long time to knead the dough into a dough, but the dough will also be unevenly stirred. Utility Model Content
[0004] The main technical problem to be solved by the utility model is to provide a tumbling dough mixer with simple structure, convenient operation, high dough kneading efficiency, uniform stirring, stirring without dead angles, high dough kneading quality and convenient material feeding.
[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:
[0006] A rolling dough mixer comprises two support frames symmetrically arranged at a certain distance, a dough mixing barrel is rotatably arranged between the two support frames, a turning assembly for driving the dough mixing barrel to turn over is arranged between the dough mixing barrel and the support frames, and a stirring assembly for mixing dough and water evenly is arranged in the dough mixing barrel;
[0007] The stirring assembly includes a stirring shaft rotatably arranged in the dough kneading barrel, the bottom end of the stirring shaft rotates and passes through the bottom of the dough kneading barrel and is transmission-connected to a stirring motor, at least two stirring blade groups are staggered up and down on the stirring shaft along its axial direction, the stirring blade group includes at least three arc-shaped stirring frames, both ends of the arc-shaped stirring frames are fixedly connected to the stirring shaft, and the multiple arc-shaped stirring frames are distributed in a circular shape at equal intervals along the circumference of the stirring shaft.
[0008] The following is a further optimization of the above technical solution by the utility model:
[0009] A first bearing is provided at the contact between the stirring shaft and the outer side wall of the dough mixing barrel. The inner ring of the first bearing is fixedly connected to the stirring shaft, and the outer ring of the first bearing is fixedly connected to the dough mixing barrel.
[0010] Further optimization: The flipping assembly includes a support sleeve fixedly sleeved on the outer side of the dough mixing barrel. Rotating shafts are fixedly connected to the opposite sides of the support sleeve, and the other ends of the rotating shafts are respectively rotatably connected to the corresponding support frames.
[0011] Further optimization: A driving motor is fixedly connected to the outer side wall of one of the support frames, and the power output end of the driving motor is in transmission connection with the corresponding rotating shaft.
[0012] Further optimization: Second bearings are provided at the connections between the two ends of the rotating shaft and the support frame. The inner ring of the second bearing is fixedly connected to the rotating shaft, and the outer ring of the second bearing is fixedly connected to the rotating shaft.

[0018] Through the cooperative setting of the dough mixing barrel, the stirring assembly and the flipping assembly, the utility model realizes that when the stirring assembly continuously stirs the flour and water in the dough mixing barrel, the dough mixing barrel is simultaneously continuously flipped. As a result, the areas that cannot be reached by the stirring shaft move inward under the action of gravity, so that the flour in the dough mixing barrel not only rotates horizontally but also rotates vertically, enabling the raw materials to be fully stirred without dead angles and enabling all-round dough mixing. Furthermore, it not only greatly improves the dough forming efficiency but also improves the uniformity of stirring, and effectively solves the problem that the existing dough mixer has insufficient stirring, resulting in poor dough mixing quality and affecting subsequent processing.

Detailed Embodiment
[0025] As Figures 1 - 3 shown, a tumbling dough mixer includes two support frames 1 symmetrically arranged at a certain distance apart. A dough mixing barrel 2 is rotatably arranged between the two support frames 1. A turning-over assembly 3 for driving the dough mixing barrel 2 to turn over is arranged between the dough mixing barrel 2 and the support frames 1. A stirring assembly 4 for evenly mixing the flour and water is arranged in the dough mixing barrel 2;
[0026] The stirring assembly 4 includes a stirring shaft 41 rotatably arranged in the dough mixing barrel 2. The bottom end of the stirring shaft 41 rotatably penetrates through the bottom of the dough mixing barrel 2 and is drivingly connected with a stirring motor 42. At least two stirring blade groups are arranged up and down at intervals along the axis of the stirring shaft 41. Each stirring blade group includes at least three arc-shaped stirring frames 43. Both ends of the arc-shaped stirring frames 43 are fixedly connected with the stirring shaft 41. The multiple arc-shaped stirring frames 43 are annularly and equally spaced along the circumferential direction of the stirring shaft 41.
[0027] With such a design, first of all, the two support frames 1 are symmetrically arranged to provide stable support for the dough mixing barrel 2, ensuring that the dough mixer remains balanced during operation, reducing shaking and vibration, and improving the stability and reliability of the equipment.
[0028] Secondly, the dough kneading barrel 2 can be turned over by the setting of the turning component 3, which is convenient for taking out and cleaning the dough. At the same time, the dough can also be stirred at different angles to improve the uniformity of the dough.
[0029] Thirdly, by staggering at least two stirring blade groups up and down, the stirring levels and range are increased, so that the dough can be fully stirred at different heights, avoiding stirring dead corners; at the same time, multiple arc-shaped stirring frames 43 are distributed in a circular shape at equal intervals along the circumference of the stirring shaft 41, further improving the uniformity of stirring and ensuring that each part of the dough can be subjected to the same stirring force.
[0030] A first bearing 5 is provided at the contact point between the stirring shaft 41 and the outer wall of the dough mixing barrel 2 . The inner ring of the first bearing 5 is fixedly connected to the stirring shaft 41 , and the outer ring of the first bearing 5 is fixedly connected to the dough mixing barrel 2 .
[0031] With this design, firstly, the first bearing 5 replaces the sliding friction of the direct contact between the stirring shaft 41 and the dough barrel 2 with rolling friction, thereby reducing the friction coefficient, reducing energy loss, extending the service life of the stirring shaft 41 and the dough barrel 2, and avoiding frequent replacement of parts due to excessive friction.
[0032] Secondly, the first bearing 5 provides stable support and guidance for the stirring shaft 41, so that the stirring shaft 41 does not deviate or shake during rotation, thereby improving the uniformity and stability of stirring and ensuring that the dough is fully and evenly stirred; at the same time, stable rotation reduces noise and vibration, allowing the dough mixer to run more quietly and smoothly, improving the user experience.
[0033] The flip assembly 3 includes a support sleeve 31 fixedly sleeved on the outer side of the dough barrel 2, and the sides of the support sleeve 31 facing away from each other are fixedly connected with a rotating shaft 32, and the other ends of the rotating shaft 32 are rotatably connected to the corresponding support frame 1.
[0034] A driving motor 33 is fixedly connected to the outer side wall of one of the support frames 1 , and a power output end of the driving motor 33 is drivingly connected to the corresponding rotating shaft 32 .
[0035] The driving motor 33 is started, and the driving motor 33 rotates to drive the corresponding rotating shaft 32 to rotate. The rotating shaft 32 rotates through the supporting sleeve 31 to drive the dough barrel 2 to flip, and at the same time, the stirring motor 42 is started, and the stirring component 4 stirs at the same time.
[0036] With such a design, when the stirring assembly 4 continuously stirs the flour and water in the dough mixing bucket 2, the dough mixing bucket 2 rotates continuously at the same time. As a result, in areas that the stirring shaft 41 cannot reach, under the action of gravity, an inward movement occurs, causing the flour in the dough mixing bucket 2 to rotate not only horizontally but also vertically. This enables the raw materials to be fully stirred without dead spots and allows for dough kneading in all directions. Consequently, not only is the efficiency of forming dough significantly improved, but also the uniformity of stirring is enhanced. At the same time, it effectively solves the problem that the existing dough mixer has insufficient stirring, resulting in poor dough quality and affecting subsequent processing.
[0037] In addition, after the dough stirring is completed, the drive motor 33 drives the mouth of the dough mixing bucket 2 to rotate downward and invert through the rotating shaft 32, which facilitates the downward inversion of the mouth of the bucket. This, in turn, makes it easier to take out the dough and quickly clean and rinse, improving labor efficiency, reducing labor intensity, effectively avoiding residues, and enhancing product quality.
[0038] Both ends of the rotating shaft 32 are provided with second bearings 34 at the connection with the support frame 1. The inner ring of the second bearing 34 is fixedly connected to the rotating shaft 32, and the outer ring of the second bearing 34 is fixedly connected to the rotating shaft 32.
[0039] With such a design, first of all, through the setting of the second bearing 34, rolling friction is used instead of the sliding friction of the direct contact between the rotating shaft 32 and the support frame 1, reducing the friction coefficient and energy loss, extending the service life of the rotating shaft 32 and the support frame 1, and reducing the cost of replacing components.
[0040] Secondly, the second bearing 34 provides stable support and guidance for the rotating shaft 32, ensuring smooth rotation of the rotating shaft 32. This, in turn, improves the inversion accuracy and stability of the dough mixing bucket 2, guaranteeing safe and reliable operation.
[0041] In addition, the standardized design makes installation convenient. When the second bearing 34 fails, it is easy to replace without the need for large-scale disassembly and repair of the rotating shaft 32 or the support frame 1, reducing maintenance costs and improving maintainability.
[0042] Finally, different types and specifications of bearings can be selected according to requirements to meet the needs of the dough mixer under different conditions such as heavy load, high-speed rotation, waterproof and dustproof, etc., improving the adaptability and reliability of the equipment.
[0043] One side of the top of the dough mixing bucket 2 is hinged with a bucket cover 6. The outer wall of the other side of the bucket cover 6 is connected to the outer wall of the other side of the dough mixing bucket 2 through a buckle lock 7, and a handle is fixedly installed on the top of the bucket cover 6.
[0044] With such a design, the handle makes it convenient for the operator to open the bucket cover 6. Through the setting of the buckle lock 7, it can ensure that the bucket cover 6 is firmly sealed with the dough mixing bucket 2, and locking and unlocking are extremely convenient and simple, facilitating user operation.
[0045] The snap lock 7 is a prior art and will not be described in detail herein, and it can be obtained by purchase.
[0046] A sealing ring is provided at the bottom of the bucket lid 6. The sealing ring is made of rubber material. With this design, the sealing performance of the bucket lid 6 on the dough mixing bucket 2 is enhanced, effectively preventing water from flowing out of the bucket mouth when the dough mixing bucket 2 is turned over.
[0047] The bucket lid 6 is made of a transparent material. With this design, it is convenient to observe the dough mixing situation inside the dough mixing bucket 2.
[0048] The support frame 1 includes a base 11. A support plate 12 is fixedly installed on the top of the base 11. Drill bolts 13 are threadedly connected to the four corners of the base 11.
[0049] With this design, the device is firmly fixed, improving the stability during stirring and turning.
[0050] For specific use, first open the snap lock 7, then open the bucket lid 6 through the handle. After that, add flour and water into the dough mixing bucket 2. After the feeding is completed, close the bucket lid 6 and close the snap lock 7.
[0051] Start the driving motor 33. The driving motor 33 rotates to drive the corresponding rotating shaft 32 to rotate. The rotation of the rotating shaft 32 drives the dough mixing bucket 2 to turn over through the support sleeve 31. At the same time, start the stirring motor 42. The stirring motor 42 rotates to drive the stirring shaft 41 to rotate. The stirring shaft 41 drives the arc-shaped stirring frame 43 to stir the flour and water, so that the flour and water are evenly mixed and evenly kneaded into dough.
[0052] When the dough stirring is completed, when the bucket mouth of the dough mixing bucket 2 is rotated to be downward inverted, stop the driving motor 33. Then place the loading box below the bucket mouth, open the snap lock 7, open the bucket lid 6, and the dough slides downward from the dough mixing bucket 2 under the action of its own gravity, which is convenient for taking out the dough and improves the feeding speed.
[0053] Adopting the above technical solution, the utility model has a simple structure, convenient operation, high dough forming efficiency, uniform stirring, no dead angle in stirring, high dough mixing quality, and convenient feeding.
[0054] For those of ordinary skill in the art, according to the teachings of the present utility model, without departing from the principles and spirit of the present utility model, the changes, modifications, substitutions and variations made to the embodiments still fall within the protection scope of the present utility model.
