Description

TECHNICAL FIELD

[0001] The utility model belongs to starch product food production field, concretely relates to a kind of extrusion type starch noodle paste laying ration mechanism. BACKGROUND

[0002] Starch product (especially vermicelli) in production process, inject the slurry prepared into slurry storage tank, cooperate with slurry storage tank by type roller, utilize the viscosity of slurry, form layer by a type roller with slurry wrapping out, and send to conveying steel belt, after being sent into steaming process steaming, carry out cooling setting (for example, application number CN2016206543078, sweet potato vermicelli quick aging device).In this process, since slurry does not have uniformity (i.e. each part slurry dilution, viscosity is different), so the amount of slurry wrapped on type roller every moment will have big difference, lead to the vermicelli produced uneven thickness, on the other hand, this paste laying mode is difficult to carry out efficient production, type roller rotation speed too fast will further lead to slurry wrapping uneven.

[0003] The principle of extruder can be applied to the above-mentioned paste laying work, the paste laying speed is changed by changing the extrusion pressure and speed, but the traditional extruder cannot be directly applied to the work, because when the material is extruded by the extruder, the material has been shaped, and the shape is determined by the extrusion port. In the production process of starch noodles, the paste is only distributed to the conveying steel belt, and the starch paste carried by the conveying steel belt passes through the steaming box and the cooler in turn to be cooked and cooled to be shaped (for reference to CN201810738509.4, straight vermicelli processing machine and processing method, which is filed by the applicant). That is, the paste is still in a liquid state during extrusion. In order to ensure production efficiency, the width of the starch noodles in a production line can reach 2-3 m or more. Therefore, the extrusion amount of the middle part is much larger than that of the two sides along the width direction of the extrusion port (the pump cannot have the same width as the extrusion port, and only a conventional pump can be aligned with the middle of the extrusion port, such as Figure 2 ), so the extruder needs to be improved to make the paste laying more uniform. CONTENT OF THE UTILITY MODEL

[0004] To solve the above problems, the utility model provides an extrusion type starch noodle paste laying ration mechanism.

[0005] The utility model aims to realize the following manner: an extrusion type starch noodle paste laying ration mechanism, including pump 1, the discharge port of pump 1 is connected with distribution box 2 through pipeline, distribution box 2 includes sequentially fixedly connected storage section 3, guide section 4 and discharge section 5, wherein:

[0006] Storage section 3 is connected with the discharge port of pump 1 through at least two distribution pipelines 31, and the at least two distribution pipelines 31 are arranged at intervals on the storage section 3.

[0007] The guide section 4 is provided with guide holes 41 along the length direction of the distribution box 2, and the guide holes 41 are communicated with the storage section 3 at one end and communicated with the discharging section 5 at the other end.

[0008] The discharging section 5 is provided with a discharging port 51 at one end.

[0009] Further, the discharging port of the pump 1 is connected with one end of a main pipeline 11, and the other end of the main pipeline 11 is connected with one end of at least two distribution pipelines 31, and the other end of the distribution pipeline 31 is connected with the storage section 3.

[0010] Further, the farther the connection position of the distribution pipeline 31 with the storage section 3 is from the center line of the storage section 3, the greater the maximum flow of the distribution pipeline 31 is.

[0011] Further, the farther the distribution pipeline 31 connected with the storage section 3 is from the center line of the storage section 3, the more dense the distribution pipeline 31 is.

[0012] Further, the guide holes 41 are variable-diameter holes, and the cross-sectional area of the guide holes 41 decreases from the storage section 3 to the discharging section 5.

[0013] Further, the axes of all the guide holes 41 are parallel to each other.

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] As attached Figures 1-2 As shown, an extrusion-type rice noodle sheet spreading and metering mechanism includes a pump 1, which can be a conventional liquid pump available on the market. The outlet of the pump 1 is connected to a distribution box 2 via a pipeline. The distribution box 2 includes a storage section 3, a guide section 4, and an outlet section 5, which are fixedly connected in sequence.

[0028] The material storage section 3 is connected to the outlet of the pump 1 through at least two distribution pipes 31. The at least two distribution pipes 31 are spaced apart on the material storage section 3 to make the feeding in the longer distribution box 2 more uniform.

[0029] Guide section 4, guide holes 41 are provided at intervals along the length of distribution box 2 on guide section 4, one end of guide hole 41 is connected to storage section 3, and the other end of guide hole 41 is connected to discharge section 5;

[0030] The discharge section 5 is provided with a discharge port 51 at one end, and at least two adjusting mechanisms for adjusting the size of the discharge port 51 are arranged along the length direction of the discharge port 51.

[0031] In detail, the storage section 3, the guide section 4 and the discharge section 5 can be produced in sections, and the end is fixed with a flange plate. The abutment between the components is realized by the flange plate and fixed by bolts. A sealing ring or sealing welding can be further provided.

[0032] Preferably, the storage section 3 and the discharge section 5 are both of a reducing structure with a width decreasing from top to bottom, which can be conical or funnel-shaped.

[0033] As shown in the accompanying drawings, Figure 1 This kind of extrusion type vermicelli laying mechanism is arranged in the existing vermicelli production line. For details, see the CN201810738509.4, Straight vermicelli processing machine and processing method, which is proposed by the applicant. The inlet of the pump 1 is connected to the vermicelli slurry production and stirring mechanism through a pipeline. The lower part of the distribution box 2 is a continuously circulating steel belt. The front is a long steaming box. The cooling box is arranged behind the steaming box. The vermicelli slurry is still in a slurry state when it falls onto the steel belt. It is steamed and preliminarily shaped through the steaming box, and is completely shaped through the cooling box.

[0034] Further, one end of the main pipeline 11 connected to the discharge port of the pump 1, and the other end of the main pipeline 11 is connected to one end of at least two distribution pipelines 31. The other end of the distribution pipeline 31 is connected to the storage section 3.

[0035] Further, in order to produce 2-3m or even wider vermicelli, the distribution box also needs to be as wide. Due to the limitation of the width of the pump 1, the pressure and flow rate of the vermicelli slurry in the distribution pipeline 31 closer to the middle will be larger. This is because the distribution pipeline 31 closer to the outside is longer and has a larger elbow angle, resulting in a larger flow rate and pressure loss. In order to make the discharge more uniform, the distribution pipeline 31 needs to be adjusted.

[0036] As a solution, as shown in the accompanying drawings, Figure 3 When the connection between the distribution pipeline 31 and the storage section 3 is farther away from the center line of the storage section 3, the maximum flow rate of the distribution pipeline 31 is larger. That is, the connection between the distribution pipeline 31 and the storage section 3 is arranged outward, and a larger size of the distribution pipeline 31 is used.

[0037] As another solution, as shown in the accompanying drawings, Figure 4 The distribution pipeline 31 connected to the storage section 3 is denser when it is farther away from the center line of the storage section 3. That is, the distance between the connection of the distribution pipeline 31 and the storage section 3 is smaller when it is closer to the two side edges of the storage section 3.

[0038] Through the above scheme, the slurry entering different positions of the storage section 3 is uniformly homogenized as a whole, and the condition of excessive pressure in the middle part is improved.

[0039] Further, as shown in the accompanying drawings, Figure 5 The guide hole 41 is a variable-diameter hole, and the cross-sectional area of the guide hole 41 decreases from the storage section 3 to the discharge section 5; the axes of all guide holes 41 are parallel to each other.

[0040] Preferably, the guide hole 41 is a hole body structure arranged along the length direction of the distribution box 2 on the whole closed guide section 4. The purpose of the above two features is that the pressure and flow direction of the slurry entering the storage section 3 from the distribution pipeline 31 are both diffused downward in a wave shape, and the pressure formed at the outlet of each distribution pipeline 31 interferes with each other, which is not conducive to the stability and uniformity of the final discharge. Therefore, through the guide hole 41, the flow direction is guided on one hand, and the variable-diameter structure is used for convergence and further pressure regulation on the other hand.

[0041] The above structure mainly plays a role in pressure regulation and homogenization for a feeding condition of 2-3m or even longer, but when actually discharging, the above structure still cannot make the discharge completely uniform, and the condition of larger pressure in the middle part or larger pressure on both sides may still lead to uneven discharge.

[0042] Therefore, further, an extrusion type noodle sheet paving machine extrusion outlet adjusting structure is proposed, which comprises a distribution box 2, the end of the distribution box 2 is provided with a discharge outlet 51, the discharge outlet 51 comprises a bottom plate 52 and an adjusting plate 53, the discharge outlet 51 is formed between the bottom plate 52 and the adjusting plate 53, at least two adjusting mechanisms are arranged at intervals along the length direction of the adjusting plate 53, the adjusting mechanisms are used for cooperating with the adjusting plate 53 to change the distance between the part of the adjusting plate 53 corresponding to the adjusting mechanism and the bottom plate 52.

[0043] Through the adjusting mechanism of the discharge outlet 51, the size of the discharge outlet 51 at the corresponding position is adjusted to change the flow rate at that position, so that the overall discharge can be more uniform

[0044] As a basic scheme, as shown in the accompanying drawings, Figure 6 The bottom plate 52 is a U-shaped plate, the adjusting plate 53 is arranged on the top of the bottom plate 52, the bottom plate 52 is fixedly connected with door-shaped frames 54, the two sides of the bottom plate 52 are respectively fixedly connected with the two ends of the door-shaped frames 54, the adjusting mechanisms are arranged at intervals on the door-shaped frames 54, the adjusting mechanisms are top tightening screws 55, the end of the top tightening screw 55 is towards the adjusting plate 53, the top tightening screw 55 is provided with a locking nut 56, and the top tightening screw 55 is locked relative to the door-shaped frame 54 through one or two locking nuts 56.

[0045] In detail, the base plate 52 can be an integral structure with the discharge section 5, and the adjusting plate 53 can be hinged to the discharge section 5 at the top via a hinge, and the two can be opened by the flow of slurry during operation; or the two ends of the adjusting plate 53 can be fixedly connected to the two ends of the U-shaped structure of the base plate 52 to form an integral square structure, and the maximum opening of the discharge port 51 at the location can be limited by the tightening screw 55.

[0046] In detail, the adjusting plate 53 should be made of a softer, more easily deformable structure, such as a plastic plate or a thinner stainless steel sheet, while the base plate 52 should be made of a harder, less easily deformable structure, such as a thicker stainless steel plate, or a glass plate should be fixed to the inside of the base plate 52.

[0047] In actual use, the flow rate and pressure of the slurry in the middle of the discharge port 51 are often the highest, that is, the discharge volume is the largest. Therefore, it can be adjusted to make the gap of the discharge port 51 in the middle smaller and the gap on both sides larger. Of course, the above is the actual application situation of the applicant, and the specific adjustment should be made according to the actual working conditions.

[0048] As an advanced solution for the regulating mechanism, as shown in the appendix Figures 7-8 As shown, a soft discharge cylinder 6 is fixedly connected to one end of the distribution box 2. A base plate 52 and an adjusting plate 53 are fixedly connected to both sides of the soft discharge cylinder 6, respectively. The end of the soft discharge cylinder 6 between the base plate 52 and the adjusting plate 53 forms a discharge port 51. A frame 7 is fixedly connected to the base plate 52. The frame 7 can be directly fixed to the ground via a support frame, or it can be fixed to the body of other machines, for example... Figure 1 The frame for installing the steel belt has positioning screws 57 at both ends of the adjusting plate 53 and the frame 7, respectively. The positioning screws 57 are threaded to the frame 7, and locking nuts 56 are provided on the positioning screws 57. The positioning screws 57 are locked relative to the frame 7 and the portal frame 54 by multiple locking nuts 56, as shown in the figure, there is one locking nut 56 on each side of the portal frame 54, and one locking nut 56 at the connection between the positioning screws 57 and the frame 7. The frame 7 is fixedly connected to the portal frame 54, and the two ends of the portal frame 54 are fixedly connected to both sides of the frame 7. Adjustment mechanisms are provided at intervals on the portal frame 54. The adjustment mechanism is a tightening screw 55, the end of the tightening screw 55 faces the adjusting plate 53, and a locking nut 56 is provided on the tightening screw 55. The tightening screw 55 is locked relative to the portal frame 54 by one or two locking nuts 56.

[0049] The overall distance between the base plate 52 and the adjusting plate 53 is determined by the positioning screw 57, and the size of the discharge port 51 at the corresponding position is determined by the tightening screw 55.

[0050] The adjustment structure of the tightening screw 55 cannot make the size of the discharge port 51 arranged in a wave shape. However, in actual use, there are often only 1-2 places where the discharge is uneven, and adjustment can be made only at those places.

[0051] Further preferably, since the soft discharge cylinder 6 continuously bears outwardly expanding pressure, in order to improve strength, as shown in the accompanying drawings, the soft discharge cylinder 6 is made of rubber, and the rubber is coated with a metal wire mesh 8 to prevent damage from overexpansion. Figure 9

[0052] In actual use, the thickness can be measured by the arrangement method in the intelligent fan transparency detection system, transparency detection mechanism and detection method of CN202311619192X and the thickness detection mechanism mentioned in the chun wing powder skin manufacturing method, mechanism and intelligent fan thickness detection system of CN2023116376362, to know whether the paving and quantifying are roughly uniform, and the interval size of the discharge port 51 is adjusted by the jacking screw 55.

[0053] The above is only the preferred embodiment of the present application, it should be pointed out that for those skilled in the art, without departing from the overall concept of the present application, a number of changes and improvements can be made, which should also be considered as the protection range of the present application.​
