Description

Technical Field

[0001] This utility model relates to the field of food processing technology, specifically a support structure for a spiral mixer and a dough bucket. Background Technology

[0002] In the food processing industry, the mixing bowl of a spiral mixer is a commonly used piece of equipment, widely applied in the mixing and kneading of dough. However, most similar products on the market share a common problem: the support design for the mixing bowl is ineffective. During operation, the lack of sufficient fixation and support causes significant shaking, which not only severely affects the kneading effect and compromising dough quality but also increases the risk of machine malfunction, thus shortening the machine's lifespan.

[0003] Specifically, traditional designs often overlook the dynamic loads borne by the kneading bowl during operation, resulting in insufficient rigidity and stability in the support structure. When the bidirectional motor drives the kneading hook to rotate, the compressive force on the dough is transmitted to the kneading bowl through the hook. Due to insufficient support, the kneading bowl is prone to shifting or shaking, which not only disrupts the uniformity of the dough but may also cause unnecessary wear and impact to other parts of the machine.

[0004] Furthermore, while some products employ a fixed mixing bowl design, they still present challenges in actual operation, such as inconvenience in disassembly and cleaning. Although the tilt-type design with a detachable mixing bowl addresses these issues to some extent, it still faces the challenge of insufficient support.

[0005] To address this issue, those skilled in the art have proposed a support structure for a spiral mixer and a dough drum to solve the problems raised in the background art. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides a support structure for a spiral mixer and a dough drum to improve their stability and durability, thereby meeting the food processing industry's demand for high-quality, high-efficiency production equipment.

[0007] A support structure for a spiral mixer and a dough bucket includes a device housing, a mixing housing fixedly connected to one side of the top of the device housing, a handwheel installed on the outer side wall of the mixing housing, the mixing housing being pressed against the top of the device housing, and a dough bucket assembly provided on the other side of the top of the device housing.

[0008] Preferably, the dough assembly includes a dough mixing bowl and a dough separating rod. The dough mixing bowl is disposed at the top of the device housing, and the dough separating rod is threadedly installed on the top of the device housing near the inner side of the dough mixing bowl. The dough separating rod passes through the dough mixing bowl and is threadedly connected to the device housing.

[0009] Preferably, a bidirectional motor is installed on the inner side wall of the device housing, and a coupling is fixedly connected to the output end of the bidirectional motor. A pulley is fixedly connected to the top of the coupling, and a belt is installed on the outer side wall of the pulley. The pulley is also installed on the top of the stirring housing.

[0010] Preferably, a second pulley is installed at the top end of the stirring shell away from the first pulley, and a second pulley is installed on the inner side wall of the other end of the first belt.

[0011] Preferably, a pulley three is fixedly connected to the output end below the bidirectional motor, a pulley four is installed on the outer side wall of the pulley three, and a pulley five is installed on the inner side wall of the pulley four at the end away from the pulley three.

[0012] Preferably, the pulley five is also installed on the inner side wall of the device housing, the outer side wall of the pulley five is equipped with a belt three, and the end of the belt three away from the pulley five is equipped with a pulley six, which is also installed on the inner side wall of the device housing.

[0013] Preferably, the turntable shaft is installed together with pulley six, and the rotation of pulley six will drive the turntable shaft to rotate, causing the turntable shaft to drive the bullseye bearing to rotate.

[0014] Preferably, belt 3 and belt 2 are installed on the outer side wall of pulley 5. The force transmission of pulley 4 drives pulley 5 to rotate, which in turn drives belt 3 to rotate. A bull's eye bearing is installed between the top of the device housing and the dough mixing bucket. The dough mixing bucket is rotatably connected to the top of the bull's eye bearing.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. Significantly Improved Stability of the Kneading Bowl: By introducing bullseye bearings as a support element, the kneading bowl is effectively fixed and supported during operation. The ball bearing structure disperses the extrusion force transmitted by the dough, reducing the shaking of the kneading bowl and thus significantly improving its stability. This improvement not only enhances the kneading effect but also ensures the uniformity and quality of the dough.

[0017] 2. Extended machine lifespan: The enhanced stability of the mixing bowl reduces mechanical wear and impact caused by shaking, thus lowering the risk of machine malfunction. In the long run, this helps extend the machine's lifespan, reducing maintenance and replacement costs and saving money for users.

[0018] 3. Enhanced User Experience: The design of this invention makes the equipment more stable and reliable during operation, reducing noise and vibration and improving the user experience. At the same time, the detachable kneading bucket design facilitates cleaning and maintenance, improving the ease of use and hygiene of the equipment.

[0019] 4. High adaptability: This invention is applicable not only to spiral mixers with a detachable mixing bowl and a tilting head, but also to mixers with non-tilting head and fixed mixing bowls. This design flexibility gives this invention broad application prospects and market potential. Attached Figure Description

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0026] As attached Figure 1 To be continued Figure 4 As shown:

[0027] Example 1: This utility model provides a support structure for a spiral mixer and a dough bucket, including a device housing 1. A mixing housing 3 is fixedly connected to one side of the top of the device housing 1. A handwheel 2 is installed on the outer wall of the mixing housing 3. The mixing housing 3 is pressed against the top of the device housing 1. A dough bucket assembly is provided on the other side of the top of the device housing 1. The dough bucket assembly includes a dough mixing bucket 13 and a dough separating rod 12. The dough mixing bucket 13 is located at the top of the device housing 1. The dough separating rod 12 is threadedly installed on the top of the device housing 1 near the inner side of the dough mixing bucket 13. The dough separating rod 12 passes through the dough mixing bucket 13 and is threadedly connected to the device housing 1. A bidirectional motor 4 is installed on the inner wall of the device housing 1. A coupling 5 is fixedly connected to the output end of the bidirectional motor 4. A pulley 6 is fixedly connected to the top of the coupling 5. A belt 8 is installed on the outer wall of the pulley 6. The pulley 6 is also installed at the top of the mixing housing 3.

[0028] Specifically, before the machine starts operating, the dough mixing bowl 13 is first securely fixed to the turntable shaft 14 by tightening the dough separating rod 12. At this point, the dough mixing bowl 13 and the machine become a single unit, reducing the possibility of shaking.

[0029] A pulley 29 is installed at the top end of the stirring shell 3, away from pulley 6. A pulley 29 is also installed on the inner wall of the other end of the belt 8. A pulley 3 22 is fixedly connected to the output end of the bidirectional motor 4. A pulley 4 20 is installed on the outer wall of pulley 3 22. A pulley 5 19 is installed on the inner wall of pulley 4 20, away from pulley 3 22. Pulley 5 19 is also installed on the inner wall of the device shell 1. A belt 3 18 is installed on the outer wall of pulley 5 19. A pulley 6 17 is installed at the end of belt 3 18, away from pulley 5 19. Wheel 6 17 is also installed on the inner side wall of the device housing 1. The turntable shaft 14 is installed together with wheel 6 17. The rotation of wheel 6 17 will drive the turntable shaft 14 to rotate, so that the turntable shaft 14 drives the bull's eye bearing 15 to rotate. The outer side wall of wheel 5 19 is simultaneously equipped with belt 3 18 and belt 2 21. The force transmission of wheel 4 20 drives wheel 5 19 to rotate, so that wheel 5 19 drives belt 3 18 to rotate. A bull's eye bearing 15 is installed between the top of the device housing 1 and the dough mixing drum 13. The dough mixing drum 13 is rotatably connected to the top of the bull's eye bearing 15.

[0030] Specifically, the bidirectional motor 4 serves as the power source. Its upper output shaft drives the dough hook 11 and the turntable shaft 14 to rotate via a coupling 5, pulley 6, pulley 9, pulley 19, pulley 22, belt 8, belt 21, pulley 20, belt 18, the mixing shell 3, and the transition shaft. The rotation of the turntable shaft 14 mixes the dough, which in turn drives the mixing bowl 13 to rotate, contributing to the uniform mixing of the dough.

[0031] Working principle: Before the machine starts working, the locking tongue assembly 7 is rotated by handwheel to press the mixing shell 3 tightly onto the device shell 1. For securing the dough mixing bowl: Before the machine starts working, the dough separating rod 12 is tightened to firmly fix the dough mixing bowl 13 onto the turntable shaft 14. This step is crucial to ensure that the dough mixing bowl does not shake or shift due to pressure from the dough hook 11 during operation.

[0032] Drive of the bidirectional motor 4: The bidirectional motor 4 serves as the power source for the entire equipment. Its upper output shaft transmits power to the kneading hook 11 and the turntable shaft 14 through a series of transmission elements: coupling 5, pulley 6, pulley 9, pulley 19, pulley 22, belt 8, belt 21, pulley 20, belt 18, and the mixing shell 3. Specifically, the upper output shaft of the bidirectional motor 4 rotates sequentially through coupling 5, pulley 6, pulley 9, belt 8, and the main shaft 10, thereby driving the kneading hook 11, which is fixed at the end of the main shaft 10, to rotate. At the same time, the other output shaft of the bidirectional motor 4 also drives the turntable shaft 14 to rotate through a similar transmission path, including pulleys and belts.

[0033] Kneading and Rotation: The rotation of the kneading hook 11 mixes and kneads the dough placed in the kneading bowl 13, gradually making it more uniform. At the same time, the rotation of the turntable shaft 14 drives the entire kneading bowl 13 to rotate together. This bidirectional rotation design helps to mix the dough in all directions and improves the kneading effect.

[0034] Support and Stability: The bottom circumferential edge of the mixing bowl 13 rests on the ball bearings of two bullseye bearings 15. As a key support element, the ball bearings 15 effectively disperse the squeezing and impact forces transmitted from the dough to the mixing bowl 13, providing a stable support point. During the kneading process, even when the dough is subjected to strong squeezing from the kneading hook 11, the mixing bowl 13 maintains a stable rotation under the support of the bullseye bearings 15, significantly reducing shaking.
