Description

Technical Field

[0001] The invention relates to the technical field of material conveying, in particular to a pipeline conveying device for spraying seasoning powder based on instant food processing. Background Art

[0002] In the processing of instant foods, in order to fully meet the diverse taste needs of consumers and further improve the taste and quality of instant foods, seasoning powders are often added to instant foods. Taking fried and puffed instant foods as an example, by spraying seasoning powders of various flavors, the products can be given rich and multi-layered flavors, which significantly enhances the attractiveness of the products and thus meets the taste preferences of different consumers.

[0003] For example, in the prior art, there is an automatic cooking machine powder conveying device with a publication number of CN217806902U. During use, the powder conveying device is provided with a stirring paddle to avoid the problem of powder agglomeration in the powder barrel. However, due to the lack of measures for synchronous drying and breaking up of the powder during the conveying process, when there is too much seasoning powder in the auger shell, extrusion feeding will occur during the conveying process. This extrusion feeding method will cause the seasoning powder to agglomerate again, making it difficult to ensure the powder state after the powder is output, which has an extremely adverse effect on the subsequent spraying effect.

[0004] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0018] The beneficial effects of the present invention are as follows:

[0019] (1) The present invention firstly uses a cam plate on a rotating shaft in combination with an L-shaped plate and a sealing cone to cause the seasoning powder in the powder storage tank to be discharged intermittently and in small quantities through the discharge pipe into the feed pipe, thereby avoiding excessive seasoning powder in the feed pipe, which causes the feed screw to perform extrusion feeding, and then causes the seasoning powder to clump and be difficult to spray subsequently; then, the seasoning powder in the feed pipe is transported in intervals by multiple rotating shafts carrying corresponding feed screws, and then combined with the synchronous reciprocating linear motion and circumferential rotation of multiple breaking and heating rods, the seasoning powder is dried, and the powder is fully broken up while drying, thereby further effectively avoiding the agglomeration of the powder and improving the uniform coverage effect of the subsequent powder spraying component on the seasoning powder sprayed on the surface of the instant food;

[0021] (3) The present invention also uses the lifting pin to first drive the piston column to move completely above the feed port during the circumferential rotation of the trapezoidal lifting guide block carried by the rotating shaft, thereby causing the feed port to be intermittently opened, so that the fully dispersed seasoning powder can intermittently enter the spray hood, and the scraper plate carried by the rotating shaft rotates to flatten the accumulated seasoning powder, and then the piston column is pushed down rapidly under the compression of the return spring to spray the seasoning powder over a large area through the porous dispersion plate, thereby ensuring that the seasoning powder can be sprayed over a large area and evenly on the surface of the fast food; in addition, the triangular slow-descent guide block cooperates with the lifting pin, so that the piston column first slowly descends to block the feed port, and then quickly descends to spray the powder. Compared with the direct and rapid descent of the piston column, it can avoid causing the seasoning powder in the feed pipe to fly around, thereby affecting the amount of powder entering the spray hood.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0039] Example 1: Please refer to Figure 1-Figure 7 As shown, in the process of conveying seasoning powder, the powder is easily extruded and conveyed, resulting in powder agglomeration and affecting subsequent spraying. The following solution can be used to solve the problem;

[0040] In this embodiment, a pipeline conveying device for spraying seasoning powder based on instant food processing includes a feeding pipe 1, a powder storage tank 11 is arranged on one side of the top of the feeding pipe 1, and the powder storage tank 11 is a sealed tank body with a lid to prevent the seasoning powder from absorbing moisture in the air, resulting in the problem of moist agglomeration of the seasoning powder, and a discharge pipe 12 is fixedly connected between the bottom of the powder storage tank 11 and the feeding pipe 1, and the bottom of the powder storage tank 11 is an inverted cone structure, which is easy to discharge the seasoning powder inside, and the inside of the feeding pipe 1 is equidistantly rotatably installed with a plurality of rotating shafts 13 along its length direction, and a feeding auger 14 is fixedly connected to the rotating shaft 13, and a feeding motor 15 for driving the corresponding rotating shaft 13 to rotate is bolted to the feeding pipe 1;

[0041] A breaking up assembly 2 is provided between two adjacent groups of rotating shafts 13. The breaking up assembly 2 includes a reciprocating screw 21 fixedly connected between the two groups of rotating shafts 13. Through a plurality of rotating shafts 13 combined with the reciprocating screw 21, the corresponding feeding auger 14 is carried to perform intermittent conveying of the seasoning powder in the feeding pipe 1. At the same time, a plurality of breaking up assemblies 2 are combined to achieve drying of the seasoning powder, and the powder is fully broken up while being dried, so as to further effectively avoid agglomeration of the powder due to pushing and squeezing during the conveying process, and improve the uniform coverage effect of the subsequent powder spraying assembly 3 on the surface of the instant food;

[0042] A driving sleeve 22 is threadedly connected to the reciprocating screw 21 and is slidably connected to the rotating shafts 13 on both sides, and mounting plates 23 are symmetrically welded on both sides of the driving sleeve 22. A plurality of scattering heating rods 24 are mounted on the mounting plates 23. The rotating shaft 13 synchronously drives the reciprocating screw 21 to rotate, and drives the driving sleeve 22 to reciprocate. The driving sleeve 22 drives the plurality of scattering heating rods 24 to synchronously reciprocate and linearly move through the mounting plates 23 to dry the seasoning powder.

[0043] A powder spraying assembly 3 is provided on the feed pipe 1, and an intermittent discharging assembly 4 is provided in the discharge pipe 12. The intermittent discharging assembly 4 enables the seasoning powder in the powder storage tank 11 to be discharged into the feed pipe 1 intermittently and in small quantities through the discharge pipe 12, thereby avoiding excessive seasoning powder inside the feed pipe 1, causing the feed auger 14 to perform extrusion-type feeding, thereby aggravating the problem of seasoning powder agglomeration and difficulty in subsequent spraying.

[0044] A rotating rod 25 is rotatably mounted on the mounting plate 23, and a rotating disk 26 is fixedly connected to the bottom of the rotating rod 25, and a plurality of movable rods 27 distributed in a circular array relative to the rotating rod 25 are slidably connected to the rotating disk 26, and a scattering heating rod 24 is fixedly connected to the bottom of the corresponding movable rod 27, and an electric heating wire is arranged inside the scattering heating rod 24, and a circular plate 28 is fixedly connected to the top of the movable rod 27, and a tension spring 29 is fixedly connected between the circular plate 28 and the rotating disk 26;

[0045] By cooperating with the tension spring 29, the movable rod 27 and the circular plate 28, the bottom of the scattering heating rod 24 is always in contact with the inner wall of the feeding pipe 1 during the circumferential rotation of the multiple scattering heating rods 24 following the turntable 26, so that the seasoning powder is effectively contacted with the scattering heating rod 24, and the internal electric heating wire of the scattering heating rod 24 is energized and heated to achieve drying treatment during the seasoning powder conveying process, thereby avoiding the problem of agglomeration when the powder is extruded and conveyed.

[0046] An auxiliary groove 16 is provided on the inner wall of the feeding pipe 1 and is located directly above the corresponding reciprocating screw 21. A tooth plate 17 is fixedly connected inside the auxiliary groove 16. A gear 210 meshing with the corresponding tooth plate 17 is fixedly connected to the rotating rod 25. The rotating shaft 13 synchronously drives the reciprocating screw 21 to rotate, and under the meshing and limiting action of the gears 210 and the tooth plate 17 on the two sets of rotating rods 25, the driving sleeve 22 is restricted to follow the reciprocating screw 21 to rotate, thereby driving the driving sleeve 22 to reciprocate.

[0047] And through the reciprocating linear motion of the driving sleeve 22, combined with the meshing of the tooth plate 17 and the gear 210, the rotating rod 25 and the rotating disk 26 are caused to rotate synchronously, thereby causing the multiple scattering heating rods 24 to synchronously move in a circumferential direction, so as to increase the contact uniformity between the scattering heating rods 24 and the seasoning powder, and to synchronously dry and scatter the seasoning powder;

[0048] The cross-section of one side of the auxiliary groove 16 is a trapezoidal structure, and a universal ball is fixedly connected to the top of the rotating rod 25. With the help of multiple scattered heating rods 24, one end of each is in contact with the inner wall of the feed pipe 1, pulling the corresponding tension spring 29, forcing the universal ball to contact the auxiliary groove 16, thereby ensuring the engagement of the tooth plate 17 with the gear 210. The trapezoidal structure of the auxiliary groove 16 and the universal ball make it easy to disassemble and assemble the rotating shaft 13 from the feed pipe 1, thereby improving the convenience of maintenance.

[0049] Two groups of auxiliary push plates 211 are arranged on both sides of the bottom of the driving sleeve 22, and ear plates 212 are symmetrically welded on both sides of the top of the auxiliary push plates 211. A triangular plate 213 rotatably connected to the corresponding ear plates 212 is welded at the bottom of the mounting plate 23. With the help of the reciprocating motion of the driving sleeve 22 and the cooperation of the triangular plate 213, when the driving sleeve 22 moves away from the powder storage tank 11, the triangular plate 213 limits the deflection of the auxiliary push plates 211, thereby pushing the seasoning powder to move to the next feeding auger 14 position;

[0050] When the driving sleeve 22 moves close to the powder storage tank 11, the triangular plate 213 cannot limit the deflection of the auxiliary push plate 211, thereby avoiding the seasoning powder from moving back. The auxiliary push plate 211 is made of a lightweight material, ensuring that the seasoning powder can drive the auxiliary push plate 211 to deflect under the push of the feeding auger 14, thereby ensuring the continuity and stability of the seasoning powder during transportation inside the feeding pipe 1.

[0051] The intermittent discharge assembly 4 includes an L-shaped plate 41, a clearance groove 18 is formed through one side of the discharge pipe 12, one end of the L-shaped plate 41 extends into the discharge pipe 12 through the clearance groove 18 and is fixedly connected with an arc-shaped baffle plate 42, the L-shaped plate 41 is slidably connected to the clearance groove 18, and the arc-shaped baffle plate 42 is slidably connected to the inner wall of the discharge pipe 12, and the clearance groove 18 is blocked by the arc-shaped baffle plate 42 to prevent the seasoning powder from leaking;

[0052] The top of the arc-shaped baffle plate 42 is fixedly connected with a blocking cone 43 adapted to the discharge pipe 12. The L-shaped plate 41 reciprocates and moves up and down, thereby driving the blocking cone 43 to intermittently enter the powder storage tank 11 from the discharge pipe 12, prompting the seasoning powder in the powder storage tank 11 to be intermittently and in small quantities discharged through the discharge pipe 12 into the feed pipe 1, and with the help of the lifting and lowering movement of the blocking cone 43, the seasoning powder in the powder storage tank 11 can be discharged smoothly.

[0053] A cam plate 44 is fixedly connected to the rotating shaft 13 located below the discharge pipe 12, a guide pin 45 matched with the cam plate 44 is fixedly connected to the L-shaped plate 41, and a limit rod 19 slidably connected to the L-shaped plate 41 is fixedly connected between the powder storage tank 11 and the feed pipe 1. The limit rod 19 is arranged to cooperate with the give way groove 18 to realize the stable lifting movement of the L-shaped plate 41. During the rotation of the rotating shaft 13, the cam plate 44 is synchronously driven to rotate, and the cam plate 44 combines with the guide pin 45 to realize the reciprocating lifting movement of the L-shaped plate 41.

[0054] Example 2: Please refer to Figure 8-Figure 10 As shown, the problem of difficulty in achieving uniform powder spraying over a large area can be solved by the following solutions:

[0055] In this embodiment, the powder spraying assembly 3 includes a spraying hood 31 fixedly connected to one end of the feeding pipe 1. The bottom of the spraying hood 31 is an open structure for installing a porous dispersion plate 32. The bottom of the spraying hood 31 is fixedly connected with the porous dispersion plate 32. The porous dispersion plate 32 is used to disperse and discharge the seasoning powder entering the spraying hood 31, so as to achieve the effect of uniformly spraying the powder over a large range to cover the surface of the fast food. The spraying hood 31 is provided with a feed port 33 connected to the feeding pipe 1, so that the dried and dispersed seasoning powder in the feeding pipe 1 can enter the inside of the spraying hood 31.

[0056] A piston column 34 is slidably connected to the inside of the spray hood 31, and a plurality of sets of limiting telescopic sleeves 35 are fixedly connected between the top of the piston column 34 and the spray hood 31. A return spring 36 is fixedly connected between the piston column 34 and the spray hood 31 and on the outside of the corresponding limiting telescopic sleeves 35. The piston column 34 first moves completely to the top of the feed port 33, prompting the feed port 33 to be intermittently opened, so that the fully dispersed seasoning powder intermittently enters the spray hood 31, and then, with the help of the compression of the return spring 36, the piston column 34 is pushed down quickly to spray the seasoning powder over a large range through the porous dispersion plate 32. The limiting telescopic sleeve 35 is used to prevent the piston column 34 from rotating in the spray hood 31.

[0057] The interior of the spray hood 31 is rotatably connected to a rotating shaft 37 that cooperates with the piston column 34. The top bolt of the spray hood 31 is connected to a spray motor 38 for driving the rotating shaft 37 to rotate. The rotating shaft 37 is fixedly connected to multiple groups of scraper plates 39 that cooperate with the porous dispersion plate 32. After the seasoning powder is dispersed by the interval conveying and drying of multiple feeding augers 14 and the dispersing components 2, it enters the interior of the spray hood 31 in combination with the opening of the feed port 33, and the scraper plate 39 is driven to rotate through the rotating shaft 37 to flatten the accumulated seasoning powder to increase the spraying range.

[0058] A rotating plate 310 is fixedly connected on the rotating shaft 37 and located inside the piston column 34, and two groups of trapezoidal lifting guide blocks 311 distributed in a ring array relative to the rotating shaft 37 are fixedly connected on the top of the rotating plate 310. A lifting pin 312 that matches the corresponding trapezoidal lifting guide block 311 is fixedly connected to the inner wall of the piston column 34, and a triangular slow-down guide block 313 is fixedly connected to the top of one side of the trapezoidal lifting guide block 311. Through the cooperation of the triangular slow-down guide block 313 and the lifting pin 312, the piston column 34 first slowly descends to block the feed port 33, and then quickly descends to spray the powder. Compared with the method of directly and quickly descending the piston column 34, it can avoid causing the seasoning powder in the feeding pipe 1 to fly around, thereby affecting the amount of powder entering the spray hood 31;

[0059] The spraying motor 38 drives the rotating shaft 37 to carry the rotating plate 310 to rotate, and the rotating plate 310 drives the two sets of trapezoidal lifting guide blocks 311 to carry the corresponding triangular slow-down guide blocks 313 to rotate circumferentially. The trapezoidal lifting guide blocks 311 first cooperate with the corresponding lifting pins 312 to push the piston column 34 to move upward, so that the piston column 34 is completely moved to the top of the feed port 33, and the seasoning powder enters the inside of the spraying hood 31 and is flattened by the scraper plate 39;

[0060] After the lifting pin 312 is separated from the corresponding trapezoidal lifting guide block 311, it contacts the triangular slow-down guide block 313. The triangular slow-down guide block 313 guides the lifting pin 312, so that the piston column 34 slowly descends under the compression of the return spring 36 until the piston column 34 blocks the feed port 33 again. Then, the triangular slow-down guide block 313 is separated from the lifting pin 312, and the piston column 34 descends rapidly under the compression of the return spring 36, spraying the seasoning powder over a large range through the porous dispersion plate 32. Combined with an external conveyor belt arranged under the spray hood 31 to transport the instant food, the seasoning powder on the surface of the instant food is sprayed.

[0061] Example 3: Please refer to Figure 1-Figure 10 As shown, the present invention also provides a method for using a pipeline conveying device for spraying seasoning powder based on instant food processing, comprising the following steps:

[0062] Step 1: The seasoning powder for instant food processing is stored in the powder storage tank 11, and the feeding motor 15 drives the corresponding rotating shaft 13 to rotate, and the other rotating shafts 13 rotate synchronously with the cooperation of the reciprocating screw rod 21, thereby causing a plurality of equally spaced feeding augers 14 to rotate inside the feeding pipe 1;

[0063] Step 2: During the rotation of the rotating shaft 13, the cam plate 44 is synchronously driven to rotate. The cam plate 44, in combination with the guide pin 45, drives the L-shaped plate 41 to reciprocate and lift, thereby driving the blocking cone 43 to intermittently enter the powder storage tank 11 from the discharge pipe 12, so that the seasoning powder in the powder storage tank 11 is intermittently and in small amounts discharged into the delivery pipe 1 through the discharge pipe 12, and the seasoning powder is moved in the delivery pipe 1 through the correspondingly rotating delivery auger 14;

[0064] Step 3: The seasoning powder moves to the bottom of the driving sleeve 22 on one side thereof under the push of the feeding auger 14, and the rotating shaft 13 synchronously drives the reciprocating screw rod 21 to rotate, and under the meshing and limiting action of the gears 210 and the toothed plate 17 on the two sets of rotating rods 25, drives the driving sleeve 22 to reciprocate, and the driving sleeve 22 drives the multiple scattering heating rods 24 to synchronously reciprocate linearly through the mounting plate 23. In this process, combined with the meshing of the toothed plate 17 and the gear 210, the rotating rod 25 carries the turntable 26 to rotate synchronously, and then the multiple scattering heating rods 24 synchronously move in a circumferential direction, so as to dry and scatter the seasoning powder;

[0065] Step 4: With the help of the reciprocating motion of the driving sleeve 22 and the cooperation of the triangular plate 213, when the driving sleeve 22 moves away from the powder storage tank 11, the triangular plate 213 limits the deflection of the auxiliary push plate 211, thereby pushing the seasoning powder to move to the next feeding auger 14 position, while when the driving sleeve 22 moves close to the powder storage tank 11, the triangular plate 213 cannot limit the deflection of the auxiliary push plate 211, thereby avoiding driving the seasoning powder back;

[0066] Step 5: The spraying motor 38 drives the rotating shaft 37 to carry the rotating plate 310 to rotate, and the rotating plate 310 drives the two sets of trapezoidal lifting guide blocks 311 to carry the corresponding triangular slow-down guide blocks 313 to rotate circumferentially. The trapezoidal lifting guide blocks 311 cooperate with the corresponding lifting pins 312 to push the piston column 34 to move upward, so that the piston column 34 is completely moved to the top of the feed port 33. After the seasoning powder is transported and dried by multiple feeding augers 14 and the breaking up components 2, it enters the spray hood 31 in combination with the opening of the feed port 33, and the scraper plate 39 is driven to rotate by the rotating shaft 37 to flatten the accumulated seasoning powder;

[0067] Step six: the seasoning powder enters the spray hood 31 and falls onto the porous dispersion plate 32. After the lifting pin 312 separates from the corresponding trapezoidal lifting guide block 311, it contacts the triangular slow-down guide block 313. The triangular slow-down guide block 313 guides the lifting pin 312, so that the piston column 34 slowly descends under the compression of the return spring 36 until the piston column 34 blocks the feed port 33 again. Then, the triangular slow-down guide block 313 separates from the lifting pin 312, and the piston column 34 descends rapidly under the compression of the return spring 36, spraying the seasoning powder over a large range through the porous dispersion plate 32. Combined with an external conveyor belt arranged under the spray hood 31 to transport the instant food, the seasoning powder on the surface of the instant food is sprayed.

[0068] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
