[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, any modifications, equivalent substitutions, improvements, etc., made by those skilled in the art to all other embodiments obtained without creative effort should be included within the protection scope of the present utility model.

[0022] like Figures 1 to 5 As shown, this embodiment discloses a rice flour slurry spreading and forming device, including a frame 1. A slurry dispensing mechanism 2, a steaming box mechanism, and a conveying mechanism 4 are fixedly connected on the frame 1. A slurry spreading mechanism 3 is provided between the steaming box mechanism and the slurry dispensing mechanism 2. One end of the conveying mechanism 4 is located below the slurry spreading mechanism 3, and the other end of the conveying mechanism 4 passes through the steaming box mechanism.

[0023] The steaming box mechanism includes a steaming box fixing frame 5, a steaming box shell 6, and a steam pipe 7. One end of the steaming box fixing frame 5 is fixedly connected to the machine frame 1, the steaming box shell 6 is fixedly connected to the steaming box fixing frame 5, and the steam pipe 7 is arranged inside the steaming box shell 6 and fixedly connected to the steaming box fixing frame 5. The slurry spreading mechanism 3 is arranged between the machine frame 1 and the steaming box shell 6, and the bottom end of the slurry spreading mechanism 3 is fixedly connected to the steaming box fixing frame 5.

[0024] The steaming box mechanism is mainly used for steaming paste-like rice noodles. It uses high-temperature steam from steam pipes to steam the paste-like rice noodles that are threaded onto a ring conveyor belt inside the steaming box shell. The steam pipes are connected to external steam generating equipment.

[0025] The slurry discharge mechanism 2 includes a slurry tank 21, a slurry discharge pipe 23, a diversion pipe 22, and a slurry outlet pipe 24. The slurry tank 21 is fixedly connected to the upper end of the frame 1. Two diversion pipes 22 are symmetrically arranged at the bottom end of the slurry tank 21. One end of each diversion pipe 22 is connected to the bottom end of the slurry tank 21, and the other end of each diversion pipe 22 is connected to the slurry discharge pipe 23. The axial direction of the slurry discharge pipe 23 is perpendicular to the conveying direction of the conveying mechanism 4, and the slurry discharge pipe 23 is a circle with both ends sealed. The slurry pipe 23 is arranged in a tubular shape, with several slurry outlet holes arranged along the circumference of the bottom end of the slurry pipe 23. The slurry outlet holes are located above the slurry spreading mechanism 3. The slurry discharge pipe 24 is fixedly connected to the lowest position of the bottom end of the slurry tank 21. The top end of the slurry discharge pipe 24 is connected to the inside of the slurry tank 21. The slurry discharge pipe 24 is equipped with a slurry discharge valve for controlling the opening and closing state of the slurry discharge pipe 24. The slurry discharge pipe 24 is used to discharge the residual powder slurry in the slurry tank when the equipment stops production.

[0026] During production, the slurry in the slurry tank flows into the slurry outlet pipe through two diversion pipes, and finally falls from the slurry outlet hole at the bottom of the slurry outlet pipe into the slurry storage shell of the slurry spreading mechanism. The design of two diversion pipes can prevent the normal production of slurry processing from being affected if one of the diversion pipes fails.

[0027] The slurry tank 21 is equipped with a stirring roller 26 for stirring the slurry. The design of the stirring roller 26 can prevent the slurry in the slurry tank 21 from settling and affecting the quality of the slurry processing. The axis of the stirring roller 26 coincides with the axis of the slurry tank 21, and the stirring roller 26 is connected to the stirring motor 25 fixedly connected to the top of the frame 1.

[0028] The slurry spreading mechanism 3 includes a slurry storage shell 31, a forming roller 32, and a forming scraper 33. The slurry storage shell 31 is a rectangular column shell with an open top. The slurry storage shell 31 is located below the slurry outlet pipe 23, and the length direction of the slurry storage shell 31 is consistent with the axial direction of the slurry outlet pipe 23. The bottom end of the slurry storage shell 31 is fixedly connected to the steaming box fixing frame 5. The forming roller 32 is rotatably connected inside the slurry storage shell 31. The axial direction of the forming roller 32 is consistent with the length direction of the slurry storage shell 31. A forming scraper 33 is provided on one side of the outer circumference of the forming roller 32. The length direction of the forming scraper 33 is consistent with the axial direction of the forming roller 32, and both ends of the forming scraper 33 are fixedly connected to the slurry storage shell 31. One end of the forming scraper 33 in the width direction contacts the outer circumferential surface of the forming roller 32, and the other end of the forming scraper 33 in the width direction is inclined downward and positioned above the conveying mechanism 4. A forming motor 34 is fixedly connected to one end of the slurry storage shell 31. The forming motor 34 is drivenly connected to the forming roller 32 to drive the forming roller 32 to rotate.

[0029] The bottom of the forming roller is located inside the slurry storage shell. After the rice noodle slurry falls into the slurry storage shell, the bottom of the forming roller will come into contact with the rice noodle slurry. When the forming roller rotates under the action of the forming motor, a thin layer of rice noodle slurry will adhere to the outer wall of the forming roller. When the rotating forming roller comes into contact with the forming scraper, the thin layer of rice noodle slurry will be scraped off by the scraper and flow along the inclined scraper onto the annular conveyor belt of the conveying mechanism to form a paste-like rice noodle. Through a simple structural design, the production and processing of a thin layer of paste-like rice noodle is realized, further improving the application effect of this utility model.

[0030] The slurry spreading mechanism 3 also includes a movable rod 37 and a stirring blade 38. The axial direction of the movable rod 37 is consistent with the axial direction of the forming roller 32 and the two are arranged side by side. Both ends of the movable rod 37 are rotatably connected to the slurry storage shell 31. The stirring blade 38 is fixedly connected to the outer circumferential wall of the movable rod 37 and rotates with the movable rod 37. One end of the forming roller 32 is fixedly connected to a drive gear 35 and the drive gear 35 is coaxial with the forming roller 32. One end of the movable rod 37 is fixedly connected to a driven gear 36 and the driven gear 36 is coaxial with the movable rod 37. The driven gear 36 and the drive gear 35 are correspondingly arranged and meshed.

[0031] To prevent the slurry in the storage shell from settling and affecting the quality of the rice noodle production, a design using meshing drive and driven gears was implemented to achieve the linkage rotation of the forming roller and the moving rod. The forming roller produces the paste-like rice noodle while simultaneously driving the moving rod and stirring blades to rotate, thus agitating the slurry in the storage shell and preventing settling.

[0032] The conveying mechanism 4 includes an annular conveyor belt 44, a drive roller 41, a driven roller 43, and a sub-frame 45. The sub-frame 45 is located at the end of the steam box fixing frame 5 away from the machine frame 1 and is fixedly connected to the steam box fixing frame 5. The length directions of the drive roller 41 and the driven roller 43 are consistent with the length direction of the forming scraper 33. The drive roller 41 is rotatably connected to the sub-frame 45 and is driven by the conveying motor 42 fixedly connected to the sub-frame 45. The driven roller 43 is rotatably connected to the bottom end of the machine frame 1. The two ends of the annular conveyor belt 44 are respectively sleeved on the outside of the drive roller 41 and the driven roller 43. The middle part of the annular conveyor belt 44 passes through the steam box shell 6 and the steam pipe 7 is located between the inner peripheral walls of the annular conveyor belt 44.

[0033] The annular conveyor belt 44 includes an annular polyester mesh belt and an annular Teflon bag. The annular polyester mesh belt is sleeved on the outside of the drive roller 41 and the driven roller 43 and is driven to rotate by the drive roller 41 and the driven roller 43. The annular Teflon bag is tightly sleeved on the outside of the annular polyester mesh belt.

[0034] The double-layer structure design of the circular conveyor belt ensures the structural strength of the conveyor belt through the circular polyester mesh belt, while the circular Teflon bag prevents the paste-like powder from sticking to the conveyor belt, thus improving the conveying and steaming processing effect of the paste-like powder.

[0035] The conveying mechanism 4 also includes an adjustment assembly, which includes an adjustment cylinder 46 and a non-powered idler roller 47. There are two adjustment cylinders 46, which are symmetrically arranged on both sides of the width direction of the annular conveyor belt 44. The top ends of the two adjustment cylinders 46 are connected to the frame 1, and the bottom ends of the two adjustment cylinders 46 are rotatably connected to the two ends of the axial direction of the non-powered idler roller 47. The length direction of the non-powered idler roller 47 is consistent with the axial direction of the driven roller 43. The non-powered idler roller 47 is located at the bottom end of the outer peripheral side wall of the annular conveyor belt 44 and contacts the outer side wall of the annular conveyor belt 44.

[0036] In the design, an infrared sensor can be installed on the frame to detect whether the annular conveyor belt is tilted in the width direction, causing the conveyor belt to deviate. When the annular conveyor belt is tilted in the width direction, the extension and retraction of two adjusting cylinders controls the two ends of the unpowered idler rollers to move up and down, thereby squeezing or lifting the annular conveyor belt to adjust its height in the width direction. Ultimately, this achieves the automatic correction effect of the annular conveyor belt in the conveying mechanism, further improving the effectiveness of this utility model.

[0037] This invention employs a slurry spreading mechanism between the slurry dispensing mechanism and the steaming mechanism. During the production of rice noodle sheets, the slurry is simply poured into the slurry tank of the dispensing mechanism. The slurry then flows through a pipe into the slurry storage shell of the spreading mechanism. Driven by a forming motor, the forming roller inside the storage shell rotates, adhering the slurry to its outer sidewall. As the forming roller rotates, the slurry adhering to its outer sidewall is scraped off by a forming scraper and flows along the scraper onto the circular conveyor belt of the conveying mechanism. The rotating conveyor belt then transports the slurry to the steaming mechanism for steaming. This slurry spreading mechanism completes the production of the paste-like rice noodle sheets, eliminating the need for manual operation. This further improves the production efficiency of rice noodle sheets while achieving automated production, effectively reducing labor costs and bringing convenience to the production process.
