Description

Technical Field

[0001] This utility model relates to the field of rice noodle production technology, and in particular to a rice noodle spreading mechanism. Background Technology

[0002] In the production of rice noodle sheets, a pump is often used to transport the slurry to the spreading head, and the slurry is spread onto the conveyor belt through a flat outlet. A scraper is installed at the outlet to control the thickness.

[0003] However, in actual use, it was found that the slurry easily adheres to the scraper, leaving traces when the slurry is discharged, which affects the smoothness of the slurry and the quality of the product. The existing technology requires the machine to be stopped to replace the scraper, which affects the continuity of production. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where machine shutdown is required to replace scrapers, and to propose a powder coating mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rice noodle spreading mechanism includes a frame;

[0007] Storage bins fixed inside the frame;

[0008] The pump has its feed end connected to the storage tank via a connecting pipe;

[0009] The slurry spreading head is fixed at the opening of the frame, and its top is connected to the discharge end of the pump through a distribution pipe, while the bottom has a discharge port.

[0010] The mounting bracket is located on one side of the slurry spreading head, and a through hole is opened on its top;

[0011] A scraper is inserted through the through hole and extends to one side of the discharge port;

[0012] The width of the through hole is adapted to the alternating insertion of two scrapers. The top of the mounting bracket is provided with bolts, and the side plate is fixed to the side wall of the scraper. The side plate is sleeved with bolts and fixed with nuts.

[0013] A notch is provided at the top of the discharge port, and a sealing plate is slidably installed at the notch. The sealing plate is reset by a compression spring. When the scraper is inserted, it pushes the sealing plate to avoid it. When it is removed, the sealing plate automatically resets to close the notch.

[0014] In one possible design, a stirrer is installed inside the storage tank.

[0015] In one possible design, the slurry spreading head has a guide section inside, and the surface of the guide section has multiple guide holes along its length.

[0016] In one possible design, the surface of the slurry spreading head is rotatably provided with a threaded shaft and a fixed limiting shaft, and the mounting bracket is threadedly connected to the threaded shaft and slidably connected to the limiting shaft.

[0017] In one possible design, the scraper has a bent section at its top.

[0018] In one possible design, the bottom end of the scraper is inserted into one side of the discharge port through a notch, and one end of the sealing plate is attached to the surface of the scraper.

[0019] In one possible design, the sealing plate has a bevel that mates with the scraper.

[0020] In one possible design, the bent section has an L-shaped bend structure, making it easy for workers to handle.

[0021] In this application, during actual use, the pump is driven to draw the slurry from the storage tank, and then enters the interior of the slurry spreading head through the liquid distribution pipe. After that, the raw slurry will flow to the discharge port through the guide hole. When passing through the discharge port, the excess slurry is scraped back by the scraper, while the remaining raw slurry will flow from below to the conveyor belt behind.

[0022] During the initial installation of the scraper, first insert the scraper into the right side of the through hole, and then fit the side plate of the side wall onto the bolt on the right side. Then, fix it with a nut. At this time, the scraper will be located on one side of the discharge port. When inserting the scraper, the scraper will abut against the inclined surface of the sealing plate, thereby pushing the sealing plate to one side to make room. When the scraper needs to be replaced, simply insert the second scraper into the left side of the through hole and fix it with the bolt on the left side. When inserting the second scraper, it will continue to push the sealing plate to make room. Then, the fixation of the scraper on the right side can be released and it can be taken out, thus achieving the effect of replacement without stopping the machine, and ensuring that the thickness of the reserved discharge port is the same after the scraper is installed.

[0023] Conversely, when the scraper on the left side needs to be changed, the same method is used for replacement. However, when the scraper on the left side is removed, the sealing plate will be reset by the force of the compression spring, thus fitting into the scraper on the right side to seal the gap.

[0024] In this utility model, the starch sheet spreading mechanism, through the drive mechanism composed of a threaded shaft and a limiting shaft, can conveniently adjust the height position of the scraper, thereby facilitating the control of the spreading thickness.

[0025] In this utility model, the starch sheet spreading mechanism, through the mounting frame, can ensure that the installation position height is the same as the original scraper when replacing the scraper, without the need for secondary adjustment by the operator;

[0026] In this invention, the scraper can be replaced directly without stopping the machine, and the structure is simple and the replacement operation is convenient, which is conducive to continuous production in practice. Attached Figure Description

[0032] 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.

[0033] In one embodiment: Reference Figure 1 A slurry spreading mechanism includes: a frame 1, a storage tank 2, a slurry spreading head 7, and a scraper 15. The frame 1 is a frame structure, and the storage tank 2 is fixedly installed inside it by bolts. An agitator 3 is rotatably installed inside the storage tank 2 via bearings. The agitator 3 is driven to rotate by an external motor. The agitator 3 inside the storage tank 2 operates at a speed of 20-60 rpm to prevent starch sedimentation. The scraper 15 has a shape including rectangular, trapezoidal, or arc-shaped to adapt to different slurry flowability. Rectangular shapes are used for conventional slurries, trapezoidal shapes facilitate slurry flow, and arc-shaped shapes reduce adhesion.

[0034] refer to Figure 2-3The slurry spreading head 7 is fixed at the opening at the front end of the frame 1. Inside, along its length, is a guide section 12. Multiple guide holes 11 are evenly spaced along the axial direction on the surface of the guide section 12 to aid in slurry distribution. The guide holes 11 are either tapered (larger at the inlet, smaller at the outlet) or spiral channels to accelerate slurry flow and prevent stagnation. The top of the slurry spreading head 7 is connected to multiple distribution pipes 6 via flanges. The other end of each distribution pipe 6 is connected to a connecting pipe 5 at the discharge end of the pump 4. The feed end of the pump 4 is connected to the storage tank 2 via another connecting pipe 5, forming a slurry circulation path.

[0035] The bottom of one side of the slurry spreading head 7 has a long strip-shaped discharge port 13. The top of the discharge port 13 has a pre-set notch, and a sealing plate 14 is slidably embedded in the notch. The sealing plate 14 is equipped with a compression spring. The sealing surface of the sealing plate 14 can be made into a stepped multi-layer seal or an elastic silicone edge structure to adapt to the surface tolerance of the scraper 15. The compression spring is made of stainless steel SUS304 or carbon steel wire (wire diameter 1.0-2.0mm) and provides a 5-15N reset force to ensure that the sealing plate 14 closes immediately.

[0036] Specifically, the drive pump 4 draws the raw slurry from the storage tank 2, and then enters the slurry spreading head 7 through the liquid distribution pipe 6. The raw slurry will then flow through the guide hole 11 to the discharge port 13. When passing through the discharge port 13, the excess slurry is scraped back by the scraper 15, while the remaining raw slurry will flow from below to the conveyor belt behind.

[0037] The through hole 16 on the mounting bracket 8 can be a slotted hole (length-to-width ratio 2:1) or a double-circle hole arrangement to accommodate scrapers 15 with different cross-sectional shapes. The bent section 19 at the top of the scraper 15 is a U-shaped handle, a ring pull ring, or an L-shape for easy hand gripping and replacement. For the initial installation of the scraper 15, first insert the scraper 15 into the right side of the through hole 16, and then fit the side plate 17 of the side wall onto the bolt 18 on the right side. Then, use the nut to fix it. At this time, the scraper 15 will be located on one side of the discharge port 13. At 15 o'clock, scraper 15 will come into contact with the inclined surface of sealing plate 14, thereby pushing sealing plate 14 to move to one side to make room; when scraper 15 needs to be replaced, simply insert the second scraper 15 into the left side of the through hole 16 and fix it with the bolt on the left side. When inserting the second scraper 15, it will continue to push sealing plate 14 to make room. Then the fixation of scraper 15 on the right side can be released and it can be taken out, thereby achieving the effect of replacement without stopping the machine, and ensuring that the thickness of the reserved discharge port 13 after scraper 15 is the same.

[0038] Conversely, when the left scraper 15 needs to be changed, the same method is used for replacement. However, when the left scraper 15 is removed, the sealing plate 14 will be reset by the force of the compression spring, thereby fitting with the right scraper 15 to seal the gap.

[0039] This application can be used in the field of rice noodle production, or in other fields applicable to this application.

[0040] In another embodiment: Reference Figure 2 A slurry spreading mechanism for rice noodle production is disclosed. A threaded shaft 9 is rotatably mounted on the surface of a spreading head 7 via a bearing seat. A limiting shaft 10 is also welded to the surface of the spreading head 7, and the limiting shaft 10 is parallel to the threaded shaft 9. A mounting frame 8 is threaded onto the outer wall of the threaded shaft 9 and slidably mounted on the outer wall of the limiting shaft 10 through a through-hole. Rotating the threaded shaft 9 drives the mounting frame 8 to move axially. A transmission thread is provided between the rotating threaded shaft 9 and the mounting frame 8. For example, the rotating threaded shaft 9 and the mounting frame 8 can be positioned by thread self-locking or by other locking structures. Specifically, in this embodiment, the rotating threaded shaft 9 and the mounting frame 8 are self-locked by thread to adjust the slurry thickness. That is, rotating the threaded shaft 9 drives the mounting frame 8 to rise and fall along the limiting shaft 10, and the height change range of the scraper 15 is ±10mm. After adjustment, the gap between the bottom end of the scraper 15 and the steel strip changes synchronously, achieving precise control of the slurry thickness.

[0041] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. 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.
