Description

Technical Field

[0001] This utility model relates to the field of dough kneading equipment technology, and in particular to a dough kneading device for making small bread rolls. Background Technology

[0002] Making mini bread requires high standards for the texture, elasticity, and uniformity of the dough, and kneading equipment is key to achieving this. The kneading process directly affects the formation of gluten and the fermentation effect, thus determining the taste, fluffiness, and internal structure of the mini bread. Mechanized kneading not only ensures the stability of dough quality but also improves production efficiency, enabling standardized production of mini bread while maintaining its handmade flavor.

[0003] The prior art disclosure number CN219228829U describes a rotary dough kneading device, which includes a base, a rotating cylinder on the base, a top cover on the top cover, a fixed kneading panel and a rotary kneading roller on the top cover, the fixed kneading panel being located at the center of the rotating cylinder, and the rotary kneading roller being located on one side of the fixed kneading panel.

[0004] This device can perform kneading during the bread-making process, but it has some drawbacks in actual use: due to its fixed cylindrical structure, the dough needs to be manually removed from the top after kneading, which is not only inconvenient but also poses a safety hazard; the deep cylindrical body makes it difficult to completely remove the dough from the bottom, resulting in material waste. Furthermore, the fixed structure creates multiple cleaning dead zones, and flour easily accumulates on the rotating parts. Multiple parts need to be disassembled for thorough cleaning after each use, severely impacting work efficiency. Utility Model Content

[0026] like Figures 1 to 4As shown, a dough kneading device for making small bread includes a base 1. A dough kneading frame 8 is fixedly installed on one side of the top of the base 1. An electric lifting assembly is installed on the dough kneading frame 8. A first bearing seat 13 is fixedly connected to the movable end of the electric lifting assembly. The electric lifting assembly includes a second motor 21, which is fixedly installed inside the dough kneading frame 8. A screw 10 is fixedly connected to the drive end of the second motor 21 and passes through the dough kneading frame 8. A slide 4 is threaded onto the outer surface of the screw 10 and is fixedly connected to the first bearing seat 13. Two guide rails 7 are symmetrically fixedly connected to one side of the outer surface of the dough kneading frame 8 and are slidably connected to the slide 4. A second bearing seat 14 is fixedly connected to one side of the outer surface of the dough kneading frame 8, and the inner ring of the bearing inside the second bearing seat 14 is fixedly connected to the screw 10. The second bearing seat 14 provides support for the screw 10 and facilitates its installation.

[0027] The inner ring of the bearing built into the first bearing housing 13 is fixedly connected to a movable frame 3. A rotating assembly is installed between the movable frame 3 and the first bearing housing 13. The rotating assembly includes a third motor 12 and two meshing transmission gears 5. The third motor 12 is fixedly installed on the top of the first bearing housing 13. The drive end of the third motor 12 and the movable frame 3 are fixedly connected to the adjacent transmission gears 5. The first bearing housing 13 provides support for the movable frame 3, which facilitates the installation of the movable frame 3.

[0028] The inner surface of the movable frame 3 is rotatably connected to the kneading drum 2. The middle of the bottom of the kneading drum 2 is fixedly connected to the long shaft 11. The top of the long shaft 11 is equipped with an elastic shaft, which includes a spring 16. The spring 16 is fixedly installed in the top opening of the long shaft 11. The top of the spring 16 is fixedly connected to the spline shaft 15. The spline shaft 15 slides between the long shaft 11 and is matched with the spline sleeve 9. The top of the spline shaft 15 is chamfered, and the bottom opening of the spline sleeve 9 is also chamfered, which facilitates the insertion of the spline shaft 15 into the spline sleeve 9 under the action of the spring 16.

[0029] A first motor 18 is fixedly installed on the inner top of the kneading machine frame 8. A spline sleeve 9 is fixedly connected to the drive end of the first motor 18, and the spline sleeve 9 is matched with the elastic shaft. A rotating kneading roller 6 is provided on one side of the spline sleeve 9. A third bearing seat 22 and a fourth bearing seat 20 are fixedly installed inside the kneading machine frame 8. The inner ring of the bearing built into the third bearing seat 22 is fixedly sleeved on the spline sleeve 9, and the inner ring of the bearing built into the fourth bearing seat 20 is fixedly sleeved on the rotating kneading roller 6.

[0030] A transmission assembly is installed between the spline sleeve 9 and the rotating kneading roller 6. The transmission assembly includes a large gear 17, which is fixedly sleeved on the spline sleeve 9. A small gear 19 is meshed on the outer surface of the large gear 17, and the small gear 19 is fixedly installed on the top of the rotating kneading roller 6.

[0031] Working principle: The first motor 18 is started, driving the spline sleeve 9 to rotate. The spline sleeve 9 transmits power to the long shaft 11 through its matching elastic shaft (spline shaft 15 + spring 16), driving the kneading drum 2 to rotate around its own axis. The large gear 17 on the spline sleeve 9 drives the rotating kneading roller 6 to rotate in the opposite direction through the meshing small gear 19. The kneading roller and the rotating kneading drum 2 form relative motion, realizing multi-directional kneading of the dough.

[0032] After kneading is complete, the second motor 21 is started to drive the screw 10 to rotate, which in turn moves the slide 4 down along the guide rail 7, causing the first bearing seat 13 fixed on the slide 4 and the entire kneading drum 2 to descend synchronously. When the kneading drum 2 reaches its lowest position, the third motor 12 drives the movable frame 3 to rotate approximately 90° to 180° through the transmission gear 5, so that the opening of the kneading drum 2 faces downwards, and the dough slides out automatically due to gravity.

[0033] After the tilting is completed, the third motor 12 reverses to return the kneading drum 2 to the correct position, and the second motor 21 reverses to drive the screw 10 to lift the kneading drum 2 to the initial high position. During this process, the first motor 18 drives the spline sleeve 9 to rotate slowly, which facilitates the spline shaft 15 to enter the spline sleeve 9 under the action of the spring 16.

[0034] It should be noted that, in actual use, an existing PLC controller can be added. The PLC controller is electrically connected to the first motor 18, the second motor 21, and the third motor 12 to facilitate overall control. The specific data analysis and processing involved to further realize the control function are methods that can be implemented by those skilled in the art based on common knowledge. These methods are not within the scope of this solution. The above description is merely to illustrate the beneficial effects that this hardware structure improvement can achieve, based on common knowledge.
