Description

TECHNICAL FIELD

[0001] The utility model belongs to starch product food production field, concretely relates to a extrusion formula powder skin paving slurry machine's extrusion port adjusting structure. BACKGROUND

[0002] Starch product (especially vermicelli) in the production process, inject the slurry that mixes well into the storage tank, cooperate with the storage tank through the type roller, utilize the viscosity of slurry, through a type roller, slurry is formed layer and is sent to the conveying steel band, after being sent into the steaming process, it is cooled and shaped (for example, the application number CN2016206543078, sweet potato vermicelli quick aging device). In this process, because slurry does not have uniformity (that is, the dilution, viscosity of each part of slurry is different), so the amount of slurry on the type roller at every moment will have a big difference, leading to the uneven thickness of the vermicelli produced, on the other hand, this kind of paving slurry mode is difficult to produce efficiently, and the type roller speed will further lead to uneven slurry wrapping.

[0003] The principle of extruder can be applied to the above-mentioned paving slurry work, the paving slurry 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 powder skin, the slurry is only distributed to the conveying steel belt, and the conveying steel belt carries the powder slurry and is sequentially steamed in the steaming box and cooled in the refrigerator to be shaped (for reference to CN201810738509.4, straight vermicelli processing machine and processing method proposed by the applicant). That is, the slurry is still in a liquid state during extrusion. In order to ensure production efficiency, the width of powder skin in a production line can reach 2-3m 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 be as wide as the extrusion port, and only a conventional pump can be aligned with the middle of the extrusion port, such as Figure 2 ).

[0004] Based on the above problems, a powder skin paving slurry quantifying mechanism is proposed in the following text, but because it is different from the conventional extruder material extrusion, the slurry is still in a liquid state during extrusion, and the extrusion pressure at each point is different, so the size of the discharge port needs to be adjusted to further quantify the discharge. Thus, the improvement is made. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0023] As shown in the accompanying drawings, Figures 1-2 An extrusion type noodle sheet paving and grouting quantitative mechanism, comprising a pump 1, which can be a conventional liquid pump on the market, a discharge port of the pump 1 is connected to a distribution box 2 through a pipeline, the distribution box 2 comprises a storage section 3, a guide section 4 and a discharge section 5 which are fixedly connected in sequence, wherein:

[0024] The storage section 3 is connected to the outlet of the pump 1 through at least two distribution pipes 31, and the at least two distribution pipes 31 are arranged at intervals on the storage section 3, so that the feeding in the longer distribution box 2 is more uniform.

[0025] The guide section 4 is provided with guide holes 41 arranged at intervals along the length direction of the distribution box 2, one end of the guide hole 41 is communicated with the storage section 3, and the other end of the guide hole 41 is communicated with the outlet section 5.

[0026] The outlet section 5 is provided with an outlet 51 at one end, and at least two adjusting mechanisms for adjusting the size of the outlet 51 are arranged along the length direction of the outlet 51.

[0027] In detail, the storage section 3, the guide section 4 and the outlet section 5 can be produced in sections, and the end is fixed with a flange plate, the abutment between the parts is through the flange plate and is fixed by bolts, and a sealing ring or sealing welding can be further arranged.

[0028] Preferably, the storage section 3 and the outlet section 5 are both variable-diameter structures with a width decreasing from top to bottom, which can be conical or funnel-shaped.

[0029] As shown in the accompanying drawings, Figure 1 This kind of extrusion type powder skin paving mechanism is arranged in the powder skin production line of the prior art, and details can be found in CN201810738509.4, straight powder silk processing machine and processing method, the inlet of the pump 1 is connected to the powder slurry production stirring mechanism through a pipe, the lower part of the distribution box 2 is a continuously circulating steel belt, the front is a long steaming box, and the rear of the steaming box is provided with a cooling box. The powder slurry still presents a slurry state when falling onto the steel belt, is steamed and preliminarily shaped through the steaming box, and is completely shaped through the cooling box.

[0030] Further, one end of the outlet of the pump 1 is connected to the main pipe 11, the other end of the main pipe 11 is connected to one end of the at least two distribution pipes 31, and the other end of the distribution pipe 31 is connected to the storage section 3.

[0031] Further, in order to produce powder skin with a width of 2-3 m or even wider, the distribution box also needs to be as wide, and due to the limitation of the width of the pump 1, the powder slurry entering the storage section 3 through the distribution pipe 31 must have a greater pressure and flow rate closer to the center, because the distribution pipe 31 closer to the outside is longer and has a larger elbow angle, and the flow rate and pressure loss are greater. In order to make the outlet more uniform, the distribution pipe 31 needs to be adjusted.

[0032] As a solution, as shown in the accompanying drawings, Figure 3 When the connection between the distribution pipe 31 and the storage section 3 is farther away from the center line of the storage section 3, the maximum flow of the distribution pipe 31 is greater, that is, the connection between the distribution pipe 31 and the storage section 3 is arranged outward, and a larger size of the distribution pipe 31 is used.

[0033] As another solution, as shown in the accompanying drawings, the closer to the center line of the storage section 3, the denser the distribution pipeline 31 connected to the storage section 3, that is, the closer to the two side edges of the storage section 3, the smaller the spacing between the connection of the distribution pipeline 31 and the storage section 3. Figure 4 Through the above-mentioned solution, the slurry entering different positions of the storage section 3 is uniformly homogenized, and the situation of excessive pressure in the middle is improved.

[0034] Further, as shown in the accompanying drawings, 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.

[0035] Figure 5 Preferably, the guide hole 41 is a hole body structure arranged along the length direction of the distribution box 2 on the overall closed guide section 4, and the purposes of the above two features are to make the pressure and flow direction of the slurry entering the storage section 3 from the distribution pipeline 31 spread 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, on the one hand, the flow direction is guided, and on the other hand, the variable-diameter structure is used for convergence and further pressure regulation.

[0036] The above structure mainly plays a role in pressure regulation and homogenization for a feeding condition of 2-3m or even longer, but in actual discharge, the above structure still cannot make the discharge completely uniform, and the situation of uneven discharge caused by larger pressure in the middle or on both sides still exists.

[0037] 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 along the length direction of the adjusting plate 53, the adjusting mechanism is used for cooperating with the adjusting plate 53 to change the spacing between the part of the adjusting plate 53 corresponding to the adjusting mechanism and the bottom plate 52.

[0038] Through the adjusting mechanism of the discharge outlet 51, the size of the corresponding position of the discharge outlet 51 is adjusted to change the flow rate, so that the overall discharge can be more uniform

[0039] As a basic solution, as shown in the accompanying drawings, the discharge outlet 51 is provided with a plurality of guide holes 41, and the guide holes 41 are arranged along the length direction of the discharge outlet 51.

[0040] As a basic solution, as shown in the accompanying drawings, the discharge outlet 51 is provided with a plurality of guide holes 41, and the guide holes 41 are arranged along the length direction of the discharge outlet 51. Figure 6 ​As shown in the drawings, 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 the door-shaped frame 54, the two sides of the bottom plate 52 are respectively fixedly connected with the two ends of the door-shaped frame 54, the adjusting mechanism is arranged on the door-shaped frame 54 in a spaced manner, and the adjusting mechanism is a jacking screw 55. The end of the jacking screw 55 is towards the adjusting plate 53, and the jacking screw 55 is provided with a locking nut 56. The jacking screw 55 is locked relative to the door-shaped frame 54 through one or two locking nuts 56.

[0041] In detail, the bottom plate 52 can be an integral structure with the discharge section 5, the adjusting plate 53 can be hingedly connected with the discharge section 5 at the top end, and the two ends of the adjusting plate 53 are fixedly connected with the two ends of the U-shaped structure of the bottom plate 52, so as to form an integrated mouth-shaped structure. The jacking screw 55 is used to limit the maximum opening amount of the discharge port 51 at the position.

[0042] In detail, the adjusting plate 53 should be made of a soft and easily deformed structure, for example, a plastic plate or a thin stainless steel sheet. The bottom plate 52 should be made of a hard and not easily deformed structure, for example, a thick stainless steel plate or a layer of glass plate fixed on the inner side of the bottom plate 52.

[0043] In actual use, the flow rate and pressure of the slurry in the middle of the discharge port 51 are still the largest, that is, the discharge amount is the largest. Therefore, the gap of the middle of the discharge port 51 can be adjusted to be smaller, and the gaps of the two sides can be adjusted to be larger. Of course, the above is the actual application situation of the applicant, and the specific adjustment can be made according to the actual working condition.

[0044] As a further scheme of the adjusting mechanism, as shown in the drawings, Figures 7-8 As shown in the drawings, the soft discharge cylinder 6 is fixedly connected with the ends of the distribution box 2, the two sides of the soft discharge cylinder 6 are respectively fixedly connected with the bottom plate 52 and the adjusting plate 53, and the end of the soft discharge cylinder 6 between the bottom plate 52 and the adjusting plate 53 forms the discharge port 51. The machine frame 7 is fixedly connected with the bottom plate 52. The machine frame 7 can be directly fixed with the ground through a support frame or fixed with the machine body of other machines, for example Figure 1 The machine frame in which a steel belt is installed, the positioning screw 57 is arranged between the two ends of the adjusting plate 53 and the machine frame 7, the positioning screw 57 is threadedly connected with the machine frame 7, the positioning screw 57 is provided with the locking nut 56, and the positioning screw 57 is locked relative to the machine frame 7 and the door-shaped frame 54 through a plurality of locking nuts 56. As shown in the drawings, there is one locking nut 56 on each side of the door-shaped frame 54, and there is one locking nut 56 at the connection position of the positioning screw 57 and the machine frame 7. The machine frame 7 is fixedly connected with the door-shaped frame 54, the two sides of the machine frame 7 are respectively fixedly connected with the two ends of the door-shaped frame 54, the adjusting mechanism is arranged on the door-shaped frame 54 in a spaced manner, the adjusting mechanism is the jacking screw 55, the end of the jacking screw 55 is towards the adjusting plate 53, the jacking screw 55 is provided with the locking nut 56, and the jacking screw 55 is locked relative to the door-shaped frame 54 through one or two locking nuts 56.

[0045] The overall spacing between the bottom plate 52 and the adjusting plate 53 is determined by the positioning screw 57, and the size of the corresponding position of the discharge port 51 is determined by the jacking screw 55.

[0046] The adjusting structure of the jacking screw 55 cannot make the size of the discharge port 51 in a wave shape, but in actual use, only 1-2 places are often uneven, and only the place is adjusted.

[0047] Further preferably, since the soft discharge cylinder 6 continuously bears outwardly tight pressure, in order to improve the strength, as shown in the accompanying drawings, the material of the soft discharge cylinder 6 is rubber, and the rubber is coated with a metal wire mesh 8 to prevent damage from over-expansion. Figure 9

[0048] In actual use, the thickness can be measured through the arrangement method in the intelligent fan transparency detection system, transparency detection mechanism and detection method of CN202311619192X, and the thickness detection mechanism 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 through the jacking screw 55.

[0049] The above is only a preferred embodiment of the present application, and it should be pointed out that for those skilled in the art, without departing from the overall concept of the present application, some changes and improvements can be made, which should also be considered as the protection range of the present application.​
