An automatic dough kneading device

Abstract

This utility model belongs to the technical field of food processing equipment, and particularly relates to an automatic dough kneading device, including a base plate, a barrel mechanism, a lifting mechanism, a driving mechanism, and a kneading mechanism. The barrel mechanism includes a lower motor base, a rotary motor, a turntable, a barrel bottom plate, and a barrel body. The automatic dough kneading device provided by this application, by setting a rotatable barrel mechanism and a rotatable kneading mechanism, allows the barrel body and the kneading rod to rotate simultaneously or in opposite directions, forming relative motion. This bidirectional motion mode enables the flour to form a relatively complex flow trajectory within the barrel body, effectively ensuring that the flour in all areas of the barrel is fully kneaded, improving the uniformity and quality of the dough. Because this application adopts a relative motion design between the barrel body and the kneading rod, it increases the contact opportunities and contact force between the flour and the kneading rod, enabling the kneading process to be completed in a shorter time, thus improving production efficiency.

Description

Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0035] In one embodiment of this utility model, such as Figures 1-5 As shown, an automatic dough kneading device is provided, including a base plate 1, a drum body mechanism 2, a lifting mechanism 3, a drive mechanism 4, and a dough kneading mechanism 5. The drum body mechanism 2 is fixed to the base plate 1 and is disposed on one side of the lifting mechanism 3; the lifting mechanism 3 is fixed to the base plate 1, and the drive mechanism 4 is fixed to the lifting mechanism 3 and realizes lifting movement through the lifting mechanism 3; the dough kneading mechanism 5 is fixed to the drive mechanism 4 and is disposed above the drum body mechanism 2, and the dough kneading mechanism 5 realizes rotational movement through the drive mechanism 4.

[0036] The bucket mechanism 2 includes a lower motor base 21, a rotary motor 22, a turntable 23, a bucket bottom plate 24, and a bucket body 25. The lower motor base 21 is fixed to the base plate 1 by bolts, the rotary motor 22 is fixed to the lower motor base 21 by bolts, and the turntable 23 is fixed to the output shaft of the rotary motor 22 by a key connection. The bucket bottom plate 24 is detachably connected to the turntable 23. The bucket body 25 is fixed to the bucket bottom plate 24 by welding and is located below the kneading mechanism 5.

[0037] The turntable 23 has two first mounting holes, and the bottom plate 24 of the bucket has two corresponding second mounting holes 241. The first and second mounting holes 241 overlap and are both threaded. Mounting bolts 26 are threaded into the first and second mounting holes 241 in sequence, realizing a detachable connection between the bottom plate 24 of the bucket and the turntable 23. This connection method is not only simple in structure but also easy to disassemble, facilitating the cleaning and replacement of the bucket body 25.

[0038] A guardrail 27 is welded to the side of the barrel 25. The barrel cover 54 and guardrail 27 provide a stress point and facilitate the disassembly and assembly of the barrel 25. A barrel cover 28 is provided on one side of the barrel 25. The barrel cover 28 is fixedly connected to the base plate 1 by bolts. The barrel 25 is placed inside the barrel cover 28. The barrel cover 28 further prevents flour from splashing out and plays a safety protection role, preventing operators from accidentally contacting the rotating barrel 25.

[0039] The lifting mechanism 3 includes a lifting cylinder 31 and lifting guide rods 32. The lifting cylinder 31 includes a lifting cylinder body 311 and a lifting piston rod 312. One end of the lifting cylinder body 311 is bolted to the base plate 1. One end of the lifting piston rod 312 is movably connected to the lifting cylinder body 311, and the other end is fixedly connected to the drive mechanism 4. Two lifting guide rods 32 are provided, arranged parallel and spaced apart. One end of each lifting guide rod 32 is bolted to the drive mechanism 4, and the other end movably passes through a guide hole on the lifting cylinder body 311. The lifting guide rods 32 ensure the drive mechanism 4 remains stable during lifting and lowering, preventing shaking. The lifting cylinder 31 drives the drive mechanism 4 and the kneading mechanism 5 to rise and fall, thereby adjusting the stirring height of the kneading rod 53 of the kneading mechanism 5.

[0040] The drive mechanism 4 includes a fixed plate 41, a drive motor 42, a drive shaft 43, a drive pulley 44, a driven shaft 45, a driven pulley 46, and a transmission belt 47. The fixed plate 41 is bolted to the lifting piston rod 312 and the lifting guide rod 32, respectively. The drive motor 42 is bolted to the fixed plate 41. One end of the drive shaft 43 is fixed to the output shaft of the drive motor 42 via a coupling, and the other end is keyed to the drive pulley 44. One end of the driven shaft 45 is keyed to the driven pulley 46, and the other end is fixed to the kneading mechanism 5. The transmission belt 47 is fixedly wound around the drive pulley 44 and the driven pulley 46, forming a belt drive mechanism. When the drive motor 42 operates, it drives the drive pulley 44 to rotate via the drive shaft 43. The drive pulley 44 then drives the driven pulley 46 and the driven shaft 45 to rotate via the transmission belt 47, thereby driving the kneading mechanism 5 to rotate.

[0041] The kneading mechanism 5 includes a first fixed shaft 51, a second fixed shaft 52, a kneading rod 53, a bucket lid 54, and a fixed bearing. One end of the first fixed shaft 51 is fixed to the driven shaft 45 via a coupling, and the other end is fixed to the inner ring of the fixed bearing and passes through the bucket lid 54. The second fixed shaft 52 is perpendicular to the first fixed shaft 51. One end of the second fixed shaft 52 is fixed to the first fixed shaft 51 by welding, and the other end is fixedly connected to the kneading rod 53. The kneading rod 53 is spirally arranged to enhance the kneading effect. The kneading rod 53 is located inside the bucket lid 54 and above the bucket body 25. The bucket lid 54 matches the shape of the bucket body 25 and can cover the top side of the bucket body 25 to prevent flour from splashing out from the top of the bucket body 25. The outer ring of the fixed bearing is fixed to the bucket lid 54 by bolts, and the fixed bearing can ensure the stable rotation of the first fixed shaft 51.

[0042] The kneading mechanism 5 also includes a feeding hopper 55, which is funnel-shaped to facilitate the addition of water or flour. The feeding hopper 55 is fixedly connected to the lid 54 by bolts. The bottom of the feeding hopper 55 is connected to the lid 54 and the body 25 respectively, so that the added ingredients can enter the body 25.

[0043] The working process of this utility model is as follows:

[0044] First, the lifting mechanism 3 drives the drive mechanism 4 and the kneading mechanism 5 to rise, causing the lid 54 to leave the bucket body 25.

[0045] Place an appropriate amount of flour into the container 25. If other ingredients need to be added, they can also be added through the feed hopper 55.

[0046] Start the lifting mechanism 3 to retract the lifting piston rod 312, which drives the drive mechanism 4 and the kneading mechanism 5 to descend, so that the lid 54 closes to the top side of the bucket body 25, and the kneading rod 53 extends into the flour inside the bucket body 25.

[0047] Simultaneously, the rotary motor 22 and the drive motor 42 are started. The rotary motor 22 drives the turntable 23, the bottom plate 24, and the barrel 25 to rotate. The drive motor 42 drives the first fixed shaft 51, the second fixed shaft 52, and the kneading rod 53 to rotate via the drive shaft 43, the drive pulley 44, the driven shaft 45, the driven pulley 46, and the transmission belt 47. The barrel 25 and the kneading rod 53 can rotate in the same direction (but at different speeds) or in opposite directions, forming relative motion to fully knead the flour.

[0048] After kneading is complete, turn off the rotary motor 22 and drive motor 42, and lift the kneading mechanism 5 through the lifting mechanism 3. Then, remove the mounting bolts 26 between the bottom plate 24 and the turntable 23, and remove the bucket 25 along with the kneaded dough to complete the entire kneading process.

[0049] The automatic dough kneading device provided in this application, by setting a rotatable drum mechanism 2 and a rotatable kneading mechanism 5, enables the drum 25 and the kneading rod 53 to rotate simultaneously or in opposite directions, forming relative motion. This effectively solves the problem of uneven flour mixing caused by the fixed drum 25 in traditional dough kneading devices. This bidirectional motion mode enables the flour to form a relatively complex flow trajectory within the drum 25, effectively ensuring that the flour in each area of ​​the drum 25 is fully kneaded, improving the uniformity and quality of the dough. Because this application adopts the relative motion design of the drum 25 and the kneading rod 53, it increases the contact opportunities and contact force between the flour and the kneading rod 53, enabling the kneading process to be completed in a shorter time, thus improving production efficiency.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
