[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example 1, referring to Figure 1-5 A dough kneading device for noodle production includes a base 1, a dough kneading bucket 2 connected to the base 1 via a flipping mechanism, and a splash guard 3 adapted to the dough kneading bucket 2 connected to the base 1 via a lifting mechanism. The splash guard 3 is equipped with a dual-axis dough kneading mechanism.

[0029] Specifically, the dual-shaft and surface mechanism includes an adjustable speed driver, two shafts 4 rotatably mounted on the splash cover 3, two spiral and surface blades 5 symmetrically welded to the outer walls of the two shafts 4, and two transmission gears 6 sequentially fixed and fitted onto the top ends of the two shafts 4;

[0030] Furthermore, the adjustable speed drive includes a fixed cover 7 fixedly connected to the top outer wall of the splash cover 3, a variable frequency motor 8 fixedly installed on the top outer wall of the fixed cover 7, a drive gear 9 fixedly mounted on the output shaft of the variable frequency motor 8, and a frequency modulator 10 fixedly installed on the top outer wall of the splash cover 3.

[0031] Furthermore, the output shaft of the variable frequency motor 8 passes through the top of the fixed cover 7, the frequency converter 10 is electrically connected to the variable frequency motor 8, the drive gear 9 is located between the two transmission gears 6, both transmission gears 6 mesh with the drive gear 9, and both transmission gears 6 and one drive gear 9 are located inside the fixed cover 7.

[0032] When the dual-shaft kneading mechanism is in use: the variable frequency motor 8 controls the drive gear 9 to rotate, and then the two transmission gears 6 meshing with the drive gear 9 will drive the two shafts 4 to rotate in the same direction. Then, the two spiral kneading blades 5 on the two shafts 4 rotate together in the kneading drum 2 to achieve efficient kneading. Furthermore, the speed of the variable frequency motor 8 can be flexibly adjusted by the frequency converter 10, so that the kneading speed can be flexibly adjusted according to different kneading conditions, which can effectively improve the kneading effect.

[0033] Specifically, the lifting mechanism includes a guide assembly, a mounting slot opened on one side of the base 1, a vertical lead screw 16 rotatably installed in the mounting slot, a lifting block 17 threadedly connected to the vertical lead screw 16, a motor support 18 welded to the upper outer wall of the rear side of the base 1, and a servo motor 19 fixedly installed on the outer wall of the front side of the motor support 18.

[0034] Furthermore, the output shaft of the servo motor 19 is coaxially and fixedly connected to the top of the vertical lead screw 16 through a coupling. The connection effect of the coupling can ensure the stability of the rotation of the vertical lead screw 16. The lifting block 17 is welded to the outer circumference of the splash cover 3.

[0035] Furthermore, the guide assembly includes two guide rails 20 symmetrically fixed to the front outer wall of the base 1 and two guide blocks 21 slidably connected to the two guide rails 20. Both guide blocks 21 are welded to the circumferential outer wall of the splash cover 3. Through the guiding cooperation between the two guide blocks 21 and the two guide rails 20, the stability of the lifting and lowering action of the splash cover 3 can be guaranteed.

[0036] When the lifting mechanism is in use: the vertical lead screw 16 is driven to rotate by the servo motor 19. Then, under the guidance of the guide component, the lifting block 17, which is threadedly connected to the vertical lead screw 16, can drive the splash cover 3 to achieve lifting and lowering. In this way, the dual-axis dough kneading mechanism can be placed into the dough kneading bucket 2 for dough kneading work. After the dough kneading work is completed, the dual-axis dough kneading mechanism can be reset to its original position.

[0037] Example 2, refer to Figure 2-4 and Figure 6 This embodiment is an optimization based on embodiment 1. Specifically, the flipping mechanism includes a flipping shaft 11 fixed to the outer circumference of the dough mixing bucket 2, a stepper motor 12 fixedly installed on the lower rear outer wall of the machine base 1, a worm gear 13 fixedly mounted on the output shaft of the stepper motor 12, and a worm wheel 14 fixedly mounted on one end of the flipping shaft 11.

[0038] Furthermore, the worm 13 and the worm wheel 14 mesh with each other, and a balance shaft 15 is welded to the outer circumference of the dough mixing drum 2. Both the flipping shaft 11 and the balance shaft 15 are rotatably connected to the machine base 1. The balance shaft 15 ensures the stability of the dough mixing drum 2 during the flipping process.

[0039] In this embodiment, after the dough kneading is completed, the dual-axis dough kneading mechanism is reset upward by the lifting mechanism in embodiment 1. Then, the stepper motor 12 drives the worm gear 13 to rotate. Subsequently, the worm wheel 14 meshing with the worm gear 13 drives the dough kneading bucket 2, which is fixed at one end of the flipping shaft 11, to rotate. This allows the dough kneading bucket 2 to be flipped from a vertical state to a horizontal state, which facilitates the worker's dough-taking operation and improves the dough-taking efficiency.

[0040] Working principle: First, add the required flour and water into the mixing bowl 2. Then, the servo motor 19 drives the vertical lead screw 16 to rotate forward. Then, under the guidance of the guide component, the lifting block 17, which is threadedly connected to the vertical lead screw 16, will drive the splash cover 3 to move downward until the splash cover 3 covers the mixing bowl 2.

[0041] Secondly, the variable frequency motor 8 controls the drive gear 9 to rotate, and then the two transmission gears 6 meshing with the drive gear 9 will drive the two shafts 4 to rotate in the same direction. Then, the two spiral kneading blades 5 on the two shafts 4 will rotate together in the kneading bucket 2 to achieve efficient kneading. Furthermore, the speed of the variable frequency motor 8 can be flexibly adjusted by the frequency converter 10, so that the kneading speed can be flexibly adjusted according to different kneading conditions, which can effectively improve the kneading effect.

[0042] Finally, the vertical lead screw 16 is reversed by the servo motor 19, and the lifting block 17, which is threaded to the vertical lead screw 16, will drive the splash cover 3 to reset upward. Then, the worm gear 13 is driven to rotate by the stepper motor 12, and the worm wheel 14, which meshes with the worm gear 13, will drive the dough bucket 2, which is fixed at one end of the flipping shaft 11, to rotate. This will flip the dough bucket 2 from a vertical state to a horizontal state, making it easier for workers to take out the dough and improving the dough taking efficiency.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
