[0028] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0029] 1. When mixing the sauce, the scraper rotates in opposite directions to the mixing drum, forming a reverse stirring mechanism. Combined with the first and second stirring rods, the sauce and noodles are thoroughly mixed in the relative flow. When rotating in the same direction, the stirring rods work together to scoop up the noodles and flip them down, preventing breakage when mixing with the sauce while enhancing contact uniformity. When serving, the first stirring rod gradually contracts axially from the outside to the inside, forming a multi-stage barrier zone, allowing the noodles to slide down in batches and mix the sauce through mutual contact, while also solving the problem of noodles clumping. This serving method also prevents noodles with sauce from rushing directly into the bowl, causing noodles to be washed out of the mixing drum or even out of the bowl.

[0030] 2. Through the cooperation of the sleeve, the third spring, the spiral guide rail and the slider, when the mixing drum rotates counterclockwise, the drive frame reciprocates along the axial direction of the mixing drum, driving the first stirring rods to reciprocate step by step. In this process, the multiple axially distributed first stirring rods form a curved reciprocating lifting and contracting action within the mixing drum, preventing the noodles from clumping. The repeated lifting action also increases the intensity of the tumbling of the sauce or the sauce and noodles, thereby improving the mixing effect.

[0031] 3. The rod body can be self-cleaned during the contraction of the first stirring rod and the second stirring rod, and then the inner wall of the mixing barrel can be cleaned by the axially moving scraper, and the rotating scraper can be cleaned by the scraper, so the whole can complete self-cleaning after the meal is served.

[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0051] like Figure 1 - Figure 12 As shown, the present invention provides: an intelligent noodle shop sauce mixing device, comprising a support 10 and a housing 20 with an opening at one end, the support 10 including an adjustment frame 11 for adjusting the angle of the housing 20, a bowl placement area provided on the adjustment frame 11, and the bowl placement area is located on the open side of the housing 20 for placing bowls;

[0052] A mixing assembly 30 is rotatably disposed in the housing 20. The mixing assembly 30 includes one end (e.g. Figure 1 The cylindrical mixing drum 31 is shown as having an opening (i.e., a food outlet) near the bowl placement area. The mixing drum 31 is located on the same side as the opening of the housing 20. A tumbling assembly 40 is mounted on the wall of the mixing drum 31. The tumbling assembly 40 includes a plurality of first stirring rods 41 and a drive frame 42 for adjusting the radial contraction of the first stirring rods 41 in stages relative to the wall of the mixing drum 31. The first stirring rods 41 slide radially along the mixing drum 31. When the first stirring rods 41 are extended, they stir and mix the sauce and noodles, thereby improving mixing uniformity.

[0053] The mixing drum 31 further includes a fabric stirring assembly 50, which includes a scraper 51 that rotates and is coaxially arranged in the mixing drum 31. The scraper 51 is mounted with a plurality of second stirring rods 52 that are perpendicular to the first stirring rods 41. When the adjustment frame 11 adjusts the opening of the housing 20 and the mixing drum 31 upward, the sauce or noodles are prevented from overflowing from the mixing drum 31 through the opening. Under the action of gravity, the sauce and noodles gather at the bottom of the mixing drum 31 and the scraper 51. At this time, the sauce at the bottom is mixed and stirred by the second stirring rods 52 on the scraper 51.

[0054] When the sauce is mixed, the scraper 51 rotates in the opposite direction to the mixing drum 31, so that the first stirring rod 41 and the second stirring rod 52 form a reverse stirring effect. The reverse stirring can produce a better mixing effect when the sauce flows relative to each other, so that the sauce can be mixed first. When the sauce is mixed, the robot arm pours the noodles into the mixing drum 31 through the noodle basket, and then makes the scraper 51 rotate in the same direction as the mixing drum 31. At this time, the first stirring rod 41 and the second stirring rod 52 rotate in the same direction to avoid the noodles being broken by relative rotation. At the same time, the noodles are picked up and turned over by the first stirring rod 41 and the second stirring rod 52 to contact the sauce, thereby achieving the mixing of the sauce and the noodles, completing the mechanical noodle mixing action.

[0055] When the mixed noodles are served, the robotic arm places the bowl in the bowl placement area, and then the opening of the mixing drum 31 is adjusted to tilt downward by the adjustment frame 11. At this time, multiple axially distributed first stirring rods 41 form a multi-level barrier belt, and the multiple first stirring rods 41 are driven by the driving frame 42 to retract one by one from the outside to the inside, so that the noodles slide down from bottom to top in sequence. That is to say, when the noodles are served, a part of the noodles not hanging on the first stirring rods 41 will fall into the bowl along the inclined mixing drum 31, and a part of the noodles will be hung by the first stirring rods 41 and when the noodles are served, The driving frame 42 drives the multiple first stirring rods 41 to retract one by one from the outside to the inside (from the food outlet to the bottom of the drum), so that the hung noodles can be discharged step by step through the multi-level barrier belt. Through this food discharging method, it is avoided that the noodles with sauce are directly rushed into the bowl, causing the noodles to be rushed out of the mixing drum 31 into the bowl, or the noodles are rushed out of the bowl. In addition, in the process of step-by-step food discharging of the noodles, the noodles come into contact with each other, so that the sauces on the surface come into contact with each other, which can also achieve the effect of re-mixing and avoid the problem of noodles clumping.

[0056] like Figure 3 、 Figure 10As shown, a servo electric cylinder 37 is fixed to the bottom of the mixing cylinder 31 through a bracket. The piston rod of the servo electric cylinder 37 is connected to the scraper 51, so that the scraper 51 is driven to move along the mixing cylinder 31 by the extension and contraction of the piston rod. The outer diameter of the scraper 51 is adapted to the inner diameter of the mixing cylinder 31. Therefore, when the scraper 51 moves from the inside to the outside, the scraper 51 can scrape and clean the inner wall of the mixing cylinder 31.

[0057] The second stirring rod 52 is elastically slidably inserted into the scraper 51. Under normal conditions, the second stirring rod 52 is retracted and the end thereof close to the first stirring rod 41 is coplanar with the scraper 51. A scraper 58 is fixed to the housing 20 and arranged radially along the scraper 51. The length of the scraper 58 is greater than the radius of the scraper 51 and less than the diameter of the scraper 51. This ensures that the scraper 51 can be cleaned after one rotation of the scraper 51, while preventing the scraper 58 from affecting the delivery of noodles.

[0058] When the sauce or noodles are mixed with the sauce, the scraper 51 abuts against the bottom wall of the mixing drum 31 and presses out the second stirring rod 52. The second stirring rod 52 protrudes from the outside of the scraper 51. At this time, the sauce or noodles and the sauce are mixed and stirred by the second stirring rod 52.

[0059] After discharging, the first stirring rod 41 is driven to retract by the driving frame 42. The retracting first stirring rod 41 is cleaned by the mixing drum 31, while avoiding interference with the axial movement of the scraper 51. After the second stirring rod 52 is separated from the mixing drum 31, it rebounds and retracts to be coplanar with the scraper 51 through the elastic member, and the rod wall of the second stirring rod 52 is cleaned by the scraper 51. After the scraper 51 moves axially to clean the inner wall of the mixing drum 31 and contacts the scraper 58, the scraper 58 cleans the heads of the rotating scraper 51 and the second stirring rod 52. It is worth noting that the outer surfaces of the scraper 51, the inner wall of the mixing drum 31, the first stirring rod 41, and the second stirring rod 52 are all coated with a non-stick coating to reduce oil adhesion and improve the cleaning effect.

[0060] like Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 As shown, the housing 20 includes an intermediate housing 21, the left end of the intermediate housing 21 is connected to the bottom housing 22 via a flange, and the right end is connected to the end housing 23 via a flange. The food outlet is provided on the end housing 23, and the scraper 58 is fixed to the food outlet side of the end housing 23;

[0061] The mixing cylinder 31 is coaxially rotatably mounted on the intermediate shell 21 and the end shell 23 via a plurality of bearings. A spiral guide rail 24 is fixed to the inner wall of the open end of the end shell 23.

[0062] The drive frame 42 includes a sleeve 421 that is sleeved on the mixing barrel 31 and a plurality of guide frames 422 annularly distributed on the sleeve 421. The inner diameter of the sleeve 421 is adapted to the outer diameter of the mixing barrel 31 and can move along the axial direction of the mixing barrel 31. The guide frames 422 are used to drive the first stirring rod 41 to retract step by step.

[0063] A slider 43 cooperating with the spiral guide rail 24 is fixed to one end of the guide frame 422 near the meal dispensing head. The slider 43 is a U-shaped structure, and the U-shaped opening at the upper end is a long strip opening, and the long strip opening is larger than the cross-sectional size of the spiral guide rail 24. A gap is reserved between the guide frame 422 and the end shell 23, and the spiral guide rail 24 can pass through the gap. A plurality of third springs 44 are fixed between the end of the sleeve 421 away from the guide frame 422 and the mixing drum 31. When the mixing drum 31 rotates counterclockwise, under the elastic rebound action of the plurality of third springs 44, the inner wall of the slider 43 near the meal dispensing port is always in contact with the spiral guide rail 24, and is The local spiral action of the spiral guide rail 24 causes the driving frame 42 to intermittently slide along the axial direction of the mixing drum 31. Through this intermittent reciprocating sliding, the driving frame 42 intermittently drives the first stirring rods 41 to intermittently contract in the mixing drum 31. The driving frame 42 drives the first stirring rods 41 to gradually extend and retract. Therefore, during this process, the multiple axially distributed first stirring rods 41 form a curved reciprocating lifting-contraction action in the mixing drum 31. This prevents the noodles from clumping together, and the repeated lifting action increases the tumbling intensity of the sauce or the sauce and noodles, thereby improving the mixing effect.

[0064] It is worth noting that, under the normal condition of the third spring 44, the end of the spiral guide rail 24 is placed on the U-shaped opening side of the slider 43 (that is, the width of the U-shaped opening is greater than the pitch of the spiral guide rail 24). In this way, when the mixing cylinder 31 rotates clockwise, the through end of the spiral guide rail 24 is screwed into the U-shaped opening of the slider 43. Under the action of the spiral guide rail 24, the slider 43 moves along the axial direction of the mixing cylinder 31, and then the axial movement and reciprocating movement switching adjustment of the drive frame 42 can be realized by the forward and reverse rotation of the mixing cylinder 31.

[0065] like Figure 2 、 Figure 8 、 Figure 9 、 Figure 12 As shown, a plurality of mounting seats 32 are distributed on the mixing cylinder 31, the mounting seats 32 distributed axially form a group, and there are multiple groups distributed annularly;

[0066] The guide frame 422 slides along each set of mounting seats 32 to axially guide the guide frame 422 through the mounting seats 32. The first stirring rod 41 is slidably inserted into the mounting seats 32. In order to improve the sealing between the first stirring rod 41 and the mounting seats 32, a sealing ring is embedded in the mounting seats 32. The drive shaft 411 is vertically fixed to the end of the first stirring rod 41 close to the inner wall of the housing 20.

[0067] The guide frame 422 is provided with a plurality of inclined drive slope holes 423 that cooperate with the drive shaft 411. That is, the drive shaft 411 passes through the drive slope holes 423 and is lifted and lowered by the action of the slope of the drive slope holes 423. The upper ends of the plurality of drive slope holes 423 are connected through smooth transition holes to facilitate the transition of the first stirring rod 41 during the step-by-step contraction process. When the drive shaft 411 is placed in the transition hole, the first stirring rod 41 is retracted into the mounting seat 32.

[0068] The slopes of the plurality of driving slope holes 423 gradually decrease from the outside to the inside (e.g. Figure 3 As shown), when the guide frame 422 moves from inside to outside, under the squeezing action of the slope surface of the driving slope hole 423, the multiple axially distributed first stirring rods 41 gradually slow down their contraction speed from outside to inside, thereby achieving the purpose of step-by-step contraction;

[0069] At the same time, in order to better cooperate between the driving slope hole 423 and the driving shaft 411, a bearing is coaxially fixed on the driving shaft 411 to reduce the friction coefficient with the slope surface of the driving slope hole 423.

[0070] like Figure 3 、 Figure 8 、 Figure 10 As shown, a large bevel gear ring 33 coaxially arranged with the piston rod is fixed to the bottom of the mixing cylinder 31, and the large bevel gear ring 33 is meshed with a large bevel gear 34. A second servo motor 35 that drives the large bevel gear 34 to rotate is fixed inside the housing 20. The second servo motor 35 is fixed to the inner wall of the intermediate housing 21. The output shaft of the second servo motor 35 is coaxially fixed with the large bevel gear 34, and the output shaft is rotatably connected to the bracket of the servo electric cylinder 37 through a bearing (as shown in FIG. Figure 10 As shown), to improve the stability of the large bevel gear 34 during rotation, the second servo motor 35 is then powered on to drive the large bevel gear 34 to rotate, and then the large bevel gear ring 33 and the mixing barrel 31 are driven to rotate in the housing 20 through the meshing effect.

[0071] like Figure 3 、 Figure 9 、 Figure 10 、 Figure 11As shown, the scraper 51 is coaxially fixed with a hexagonal shaft 55 that is rotatably connected to the piston rod. The hexagonal shaft 55 passes through the through hole at the bottom of the mixing barrel 31. A hexagonal sleeve 56 is sleeved on the hexagonal shaft 55, and the hexagonal sleeve 56 slides along the hexagonal shaft 55. The hexagonal sleeve 56 is connected to the scraper 51 through a second spring 57, so that the second spring 57 cushions the hexagonal sleeve 56.

[0072] The cylinder body of the servo electric cylinder 37 is rotatably connected to a small bevel gear ring 371 through a bearing. The small bevel gear ring 371 is coaxially arranged with the piston rod. The small bevel gear ring 371 is meshed with a small bevel gear 351. The small bevel gear 351 is coaxially fixed to the output shaft of the second servo motor 35. At the same time, the small bevel gear ring 371 and the large bevel gear ring 33 are placed on both sides of the bevel gear. Therefore, when the second servo motor 35 drives the large bevel gear 34 and the small bevel gear 351 to rotate, the small bevel gear ring 371 and the large bevel gear ring 33 rotate in opposite directions.

[0073] The small conical gear ring 371 is provided with a hexagonal hole adapted to fit the hexagonal sleeve 56. When the piston rod is retracted into the cylinder body and the hexagonal sleeve 56 is inserted into the hexagonal hole of the small conical gear ring 371, the hexagonal shaft 55 and the scraper 51 rotate along with the small conical gear ring 371 in the opposite direction to the mixing drum 31.

[0074] When the piston rod extends, it pushes the hexagonal shaft 55 and the scraper 51 outward, and the hexagonal sleeve 56 is disengaged from the hexagonal hole of the small conical gear ring 371. At the same time, in this state, the second stirring rod 52 still partially protrudes from the scraper 51. At this time, under the action of the friction between the scraper 51 and the mixing drum 31, when the mixing drum 31 rotates, the scraper 51 also rotates with the mixing drum 31. At the same time, in order to increase the friction coefficient between the scraper 51 and the mixing drum 31, a plurality of rubber rings are provided on the scraper 51.

[0075] When the piston rod contracts, the hexagonal sleeve 56 is again inserted into the hexagonal hole of the small bevel gear ring 371 through the buffering of the second spring 57, and the scraper 51 can be driven to rotate through the small bevel gear ring 371.

[0076] like Figure 10 、 Figure 11 As shown, the scraper 51 is annularly distributed with a plurality of stepped holes 511, and the large hole on one side close to the bottom of the mixing barrel 31 is threadedly connected to an externally threaded nut 54 to facilitate the installation of the second stirring rod 52, and the second stirring rod 52 passes through the nut 54 and the stepped hole 511, and the second stirring rod 52 is fixed with a limiting plate 521 placed in the stepped hole 511, and the side of the limiting plate 521 away from the nut 54 is fixed with a first spring 53. Therefore, when the scraper 51 does not abut against the bottom of the mixing barrel 31, under the elastic rebound action of the first spring 53, and after the limiting plate 521 abuts against the nut 54, the end of the second stirring rod 52 is coplanar with the scraper 51.

[0077] like Figure 12 As shown, the end of the first stirring rod 41 away from the driving shaft 411 is the same as the curved surface of the inner wall of the mixing barrel 31. That is to say, when the driving shaft 411 is against the transition hole, the curved end of the first stirring rod 41 at this time cooperates with the inner wall of the mixing barrel 31 to form a cylinder body. When the scraper 51 passes the end of the first stirring rod 41, the scraper 51 can scrape and clean the sauce on the first stirring rod 41.

[0078] like Figure 2 、 Figure 4 As shown, the middle shell 21 is symmetrically fixed with a flip shaft 211, and the flip shaft 211 is arranged perpendicular to the axis of the mixing drum 31. The flip shaft 211 is rotatably connected to the adjusting frame 11 through a bearing. The adjusting frame 11 is fixed with a first servo motor 27. The flip shaft 211 on one side is coaxially fixed with a worm gear 25, and the worm gear 25 is engaged with a worm 26. The adjusting frame 11 is fixed with a first servo motor 27 for driving the worm 26 to rotate. The worm 26 is driven to rotate by the forward and reverse rotation of the first servo motor 27, and the worm 26 drives the worm gear 25 and the flip shaft 211 to rotate, thereby realizing the adjustment of the angle of the food outlet, and the self-locking cooperation of the worm 26 and the worm gear 25 can position the mixing drum 31 after flipping.

[0079] like Figure 3 、 Figure 5 As shown, an electric slip ring 221 coaxially arranged with the mixing drum 31 is fixed through the bottom shell 22. The stator of the electric slip ring 221 is fixed to the bottom shell 22, and the wire of the rotor is electrically connected to the servo electric cylinder 37 and the second servo motor 35. A limit switch 36 electrically connected to the servo electric cylinder 37 is fixed on the side of the mixing drum 31 near the food outlet. When the drive frame 42 slides toward the food outlet and the first stirring rod 41 is retracted, the sleeve 421 abuts against the limit switch 36, triggering the limit switch 36.

[0080] The internal contact state of the travel switch 36 is switched (the normally closed contact is disconnected to cut off the signal of the servo electric cylinder 37 to force a shutdown, and the normally open contact is closed to send a position signal to the controller), forming a closed-loop control of "mechanical trigger-electrical signal feedback-execution response", making the overall mixing more intelligent.

[0081] Working Principle: In the mixing state, the food outlet is tilted upward, and the piston rod is in the retracted state. At this time, the scraper 51 is against the bottom of the mixing barrel 31, the second stirring rod 52 protrudes from the scraper 51, the first stirring rod 41 protrudes from the mixing barrel 31, and the hexagonal sleeve 56 is inserted into the small conical gear ring 371;

[0082] The sauce is poured into the mixing drum 31 from the food outlet by the robotic arm, and the second servo motor 35 is started to drive the large bevel gear 34 and the small bevel gear 351 to rotate. Under the action of meshing, the large bevel gear ring 33 and the small bevel gear ring 371 are driven to rotate in opposite directions. At this time, the mixing drum 31 rotates counterclockwise. At this time, the sauce is mixed by the reverse stirring of the first stirring rod 41 and the second stirring rod 52.

[0083] After the sauce is mixed, the noodles are poured into the mixing drum 31 from the food outlet. At the same time, the servo electric cylinder 37 partially extends the piston rod and disengages the hexagonal sleeve 56 from the small conical gear ring 371. The second servo motor 35 then drives the mixing drum 31 to rotate counterclockwise. The scraper 51 rotates with the mixing drum 31 under the action of friction. The first stirring rod 41 and the second stirring rod 52 then pick up the noodles and roll them to fully mix the noodles with the sauce.

[0084] After the noodles and sauce are mixed, the bowl is placed in the bowl storage area. The first servo motor 27 drives the housing 20 and the mixing drum 31 to flip and tilt the dish outlet downward. When the noodles are served, some of the noodles not caught on the first stirring rod 41 will fall into the bowl along the tilted mixing drum 31, while some of the noodles are caught by the first stirring rod 41. When the noodles are served, the second servo motor 35 drives the mixing drum 31 to rotate clockwise. The through end of the spiral guide rail 24 is screwed into the U-shaped opening of the slider 43. Under the action of the spiral guide rail 24, the slider 43 drives the guide frame 422 to move along the mixing drum 31 toward the dish outlet.

[0085] Then, the plurality of first stirring rods 41 are squeezed by the slopes of the plurality of driving holes 423, which are gradually reduced in slope from the outside to the inside, so that the plurality of first stirring rods 41 are successively contracted from the outside to the inside during rotation, so that the noodles mixed with the sauce fall into the bowl step by step;

[0086] After the meal is served, and the first stirring rod 41 is retracted into the mounting seat 32, the servo electric cylinder 37 is operated to extend the piston rod, and the second stirring rod 52 is retracted under the elastic rebound action of the first spring 53. The scraper 51 moves axially to clean the inner wall of the mixing drum 31, and after contacting the scraper 58, the mixing drum 31 rotates counterclockwise and drives the scraper 51 to rotate. At this time, the scraper 58 cleans the scraper 51.

[0087] When the scraper 58 is rotated to clean, the first stirring rod 41 is partially extended. Therefore, after cleaning is completed, the mixing drum 31 needs to be rotated clockwise again so that the first stirring rod 41 is retracted into the mounting seat 32. The scraper 51 can be reset by retracting the piston rod.

[0088] It is worth noting that the distance between the first stirring rod 41 near the food outlet and the food outlet is greater than the thickness of the scraper 51, and the second stirring rod 52 is away from the first stirring rod 41, thereby avoiding interference when cleaning the scraper 51.

[0089] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
