DETAILED DESCRIPTION
[0025] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0026] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.
[0027] In one embodiment, see Figure 1 , Figure 2 , Figure 3 and Figure 5 , a food powder stirring device for stirring evenly comprises a stirring box 1, wherein a turntable 2 is arranged inside the stirring box 1, and a side wall of the turntable 2 is slidably connected to the inner wall of the stirring box 1, wherein a rotating rod 6 runs through the turntable 2, and the rotating rod 6 is fixedly connected to the turntable 2, a plurality of stirring rods 7 are fixed below the turntable 2 and on the side wall of the rotating rod 6, a feeding channel 3 is arranged inside the turntable 2, and a mesh plate 14 is arranged inside the feeding channel 3, a limiting cylinder 12 is rotatably connected to the outside of the rotating rod 6 below the turntable 2, and a plurality of fixed rods 13 distributed in a circle are fixed outside the limiting cylinder 12, and one end of the fixed rod 13 away from the limiting cylinder 12 is fixedly connected to the inner wall of the stirring box 1, and the limiting cylinder 12 is connected to a crushing mechanism 5 and a dredging mechanism 4, the crushing mechanism 5 is used to crush the food powder agglomerated inside the feeding channel 3, and the dredging mechanism 4 is used to dredge the mesh plate 14.
[0028] In this embodiment, when the food powder is stirred, one of the food powders (hereinafter referred to as the main ingredient) is poured into the mixing box 1 and above the turntable 2 through the first feeding port 9 on the top of the mixing box 1, and the remaining food powders (hereinafter referred to as the auxiliary ingredients) are poured into the mixing box 1 and below the turntable 2 through the second feeding port 10 on the side wall of the mixing box 1. Then, the external motor 8 on the top of the mixing box 1 drives the rotating rod 6 to rotate, and the rotating rod 6 drives the turntable 2 and the stirring rod 7 to rotate. When the turntable 2 rotates, the main ingredient will enter the inside of the feeding channel 3, and the mesh plate 14 inside the feeding channel 3 will screen the main ingredient, and the powdered main ingredient will be directly discharged from the feeding channel 3. The main material will fall down from the inside of the feeding channel 3, while the agglomerated main material will accumulate on the mesh plate 14, which will screen the main material and avoid the uneven mixing of the food powder caused by the agglomerated main material. Moreover, the main material can be evenly sprinkled inside the mixing box 1 while the turntable 2 rotates, thereby avoiding the main material from being concentrated at a certain position of the mixing box 1, thus ensuring the mixing effect of the food powder. In addition, the crushing mechanism 5 will continuously crush the agglomerated powder inside the feeding channel 3 while the turntable 2 rotates, thereby avoiding the phenomenon that the agglomerated raw material blocks the mesh holes. The unblocking mechanism 4 will continuously unblock the mesh holes, thereby further avoiding the phenomenon that the mesh holes are blocked by the raw material.
[0029] See also Figure 3and Figure 4 The dredging mechanism 4 includes a bracket 43 arranged below the mesh plate 14, a plurality of dredging needles 42 are fixed on the top of the bracket 43, a connecting rod 44 is fixed on the bottom of the bracket 43, a trapezoidal block 45 is fixed on the lower end of the connecting rod 44, and the trapezoidal block 45 is connected to the bottom of the feeding channel 3 through a first elastic component 47, wherein an extrusion column 41 capable of extruding the trapezoidal block 45 is fixed on the top of the fixing rod 13;
[0030] As the turntable 2 rotates, it drives the unloading channel 3 and the trapezoidal block 45 to make circular motion. When the unloading channel 3 is about to rotate above the fixed rod 13, the extrusion column 41 will squeeze the trapezoidal block 45, so that the trapezoidal block 45 drives the bracket 43 to move upward through the connecting rod 44, and the bracket 43 drives the dredging needle 42 to pass through the inside of the mesh, and the mesh is dredged by the dredging needle 42, which can effectively avoid the phenomenon that the raw material blocks the mesh. When the trapezoidal block 45 moves to the other side of the extrusion column 41, the trapezoidal block 45 automatically moves downward under the action of the first elastic component 47, and then drives the dredging needle 42 to move downward through the connecting rod 44 and the bracket 43, and repeats this cycle, so that the mesh can be continuously dredged, wherein the first elastic component 47 can be a spring.
[0031] See also Figure 4 The top of the trapezoidal block 45 is fixed with symmetrically distributed guide rods 46, and the upper ends of the guide rods 46 extend into the interior of the material discharge channel 3 and are slidably connected to the material discharge channel 3;
[0032] The material discharge channel 3 can limit the trapezoidal block 45 through the guide rod 46, thereby effectively improving the stability of the trapezoidal block 45 when it moves up and down.
[0033] See also Figure 3 and Figure 5 The pulverizing mechanism 5 includes a fixed plate 56 which is arranged inside the material discharge channel 3 and is symmetrically distributed. A plurality of pulverizing needles 52 are fixed on the sides of the fixed plates 56 which are close to each other. The pulverizing needles 52 on the two fixed plates 56 are staggered. A support rod 53 is fixed on the sides of the fixed plates 56 which are away from each other. The support rod 53 passes through the side wall of the material discharge channel 3. One end of the support rod 53 which passes through the side wall of the material discharge channel 3 is connected to a driving component, and the driving component is used to drive the support rod 53 to move relative to each other.
[0034] The turntable 2 drives the feeding channel 3 to move in a circular motion while the driving assembly drives the support rod 53 to move back and forth. The support rod 53 drives the two groups of crushing needles 52 to move relative to each other through the fixed plate 56. The two groups of crushing needles 52 arranged in an staggered manner continuously reciprocate to crush the agglomerated raw materials inside the feeding channel 3, which can effectively prevent the agglomerated raw materials from clogging the mesh holes.
[0035] See also Figure 3 and Figure 5The driving assembly includes a plurality of extrusion blocks 51 fixed on the side wall of the limiting cylinder 12 and the inner wall of the mixing box 1 and distributed in a circumferential manner. A baffle 54 is fixed to the outside of the support rod 53, and the baffle 54 is connected to the feeding channel 3 through a second elastic component 55;
[0036] When the support rod 53 is about to rotate to the position of the extrusion block 51, the extrusion block 51 squeezes the support rod 53, so that the support rod 53 drives the crushing needles 52 to approach each other through the fixing plate 56, thereby crushing the agglomerated raw materials. When the support rod 53 moves to the other side of the extrusion block 51, the extrusion block 51 no longer squeezes the support rod 53, and the support rod 53 automatically resets under the action of the second elastic component 55 and the baffle 54, thereby driving the crushing needles 52 to move away from each other. Such a reciprocating cycle has a crushing effect on the agglomerated raw materials inside the feeding channel 3. The second elastic component 55 can be a spring, wherein the arc length of the extrusion block 51 on the inner wall of the mixing box 1 is greater than the arc length of the extrusion block 51 on the outer wall of the limiting cylinder 12, so that the extrusion time and extrusion degree of the two extrusion blocks 51 on the support rod 53 are kept consistent, thereby allowing the crushing needles 52 to move synchronously relative to each other.
[0037] In another embodiment, see Figure 6 and Figure 7 The inner wall of the mesh plate 14 is provided with symmetrically distributed first slide grooves 59, and the side wall of the mesh plate 14 is fixed with symmetrically distributed first sliders 58, and the two first sliders 58 are respectively located inside the two first slide grooves 59 and are slidably connected to the first slide grooves 59, wherein the top of the first slider 58 is connected to the inner wall of the first slide groove 59 through the third elastic component 57, and the bottom of the first slider 58 is connected to a traction component, and when the dredging mechanism 4 dredges the mesh plate 14, the traction component is used to drive the first slider 58 to move downward;
[0038] In this embodiment, when the dredging mechanism 4 dredges the mesh plate 14, the traction component drives the mesh plate 14 to move downward through the first slider 58, so that the mesh plate 14 and the dredging mechanism 4 are close to each other, which can effectively ensure the dredging effect of the dredging mechanism 4 on the mesh plate 14. After the dredging mechanism 4 has completed the dredging of the mesh plate 14, the traction component no longer pulls the first slider 58. The mesh plate 14 automatically moves upward under the action of the first slider 58 and the third elastic component 57. The third elastic component 57 can be a spring. This cycle is repeated, so that the mesh plate 14 can continuously reciprocate up and down. On the one hand, it can ensure the dredging effect of the dredging mechanism 4 on the mesh holes, and on the other hand, it can drive the raw materials above the mesh plate 14 to shake continuously, thereby improving the feeding rate.
[0039] See also Figure 7The traction assembly includes a second chute 511 arranged inside the unloading channel 3, and a second slider 510 is slidably connected inside the second chute 511. The second slider 510 is fixedly connected to the support rod 53, wherein a wire groove is provided on the side wall of the second chute 511, and the other end of the wire groove passes through the bottom of the first chute 59. The second slider 510 is fixedly connected with a traction rope 512, and the traction rope 512 passes through the inside of the wire groove and is fixedly connected to the first slider 58;
[0040] When the support rod 53 is squeezed by the squeezing block 51, the support rod 53 also drives the second slider 510 to move inside the second slide groove 511. While the second slider 510 moves, it pulls the first slider 58 through the traction rope 512, thereby driving the mesh plate 14 to move downward. When the squeezing block 51 no longer squeezes the support rod 53, the support rod 53 drives the second slider 510 to reset, and the second slider 510 no longer pulls the first slider 58 through the traction rope 512. This reciprocating cycle allows the mesh plate 14 to move up and down following the reciprocating motion of the support rod 53. The number of squeezing blocks 51 can be the same as the number of fixed rods 13, and the squeezing blocks 51 are located directly above the fixed rods 13, so that while the squeezing blocks 51 squeeze the support rods 53, the mesh plate 14 can move downward and cooperate with the dredging mechanism 4 to dredge the mesh plate 14.
[0041] See also Figure 1 A plurality of dredging rods 11 distributed in a circle are fixed above the turntable 2 and on the inner wall of the mixing box 1;
[0042] When the turntable 2 rotates, it may drive the raw materials above it to rotate synchronously, so it cannot be guaranteed that the raw materials can continuously enter the discharge channel 3. The setting of the dredging rod 11 has a pushing effect on the raw materials above the turntable 2, so that the raw materials can smoothly enter the discharge channel 3, thereby ensuring the discharge rate.
[0043] Working principle: When the food powder is stirred, the rotating rod 6 drives the turntable 2 and the stirring rod 7 to rotate. When the turntable 2 rotates, the main material will enter the inside of the feeding channel 3, and the main material will be screened by the mesh plate 14 inside the feeding channel 3. The powdered main material falls directly from the inside of the feeding channel 3, while the agglomerated main material accumulates on the mesh plate 14, which plays a screening role for the main material, and can avoid the uneven mixing of the food powder caused by the agglomerated main material. In addition, when the turntable 2 rotates, the main material can be evenly sprinkled inside the mixing box 1, thereby avoiding the concentration of the main material. At a certain position of the mixing box 1, the mixing effect of the food powder is guaranteed. When the feeding channel 3 rotates, the support rod 53 and the trapezoidal block 45 are also driven to rotate. When the trapezoidal block 45 rotates to the position of the fixed rod 13, the extrusion column 41 will squeeze the trapezoidal block 45, so that the trapezoidal block 45 drives the bracket 43 to move upward through the connecting rod 44, and the bracket 43 drives the dredging needle 42 to pass through the inside of the mesh. The mesh is dredged by the dredging needle 42, which can effectively avoid the phenomenon that the raw material blocks the mesh. In addition, when the trapezoidal block 45 rotates to the position of the fixed rod 13, the side of the limiting cylinder 12 The extrusion blocks 51 on the wall and the extrusion blocks 51 on the inner wall of the mixing box 1 respectively squeeze the two support rods 53, and the support rods 53 drive the crushing needles 52 to approach each other through the fixing plate 56. The staggered crushing needles 52 crush the agglomerated raw materials inside the feeding channel 3, which can prevent the agglomerated raw materials from blocking the mesh holes. When the support rods 53 are squeezed, they also drive the second slider 510 to move inside the second slide groove 511. When the second slider 510 moves, it pulls the first slider 58 through the traction rope 512, thereby driving the mesh plate 14 to move downward. This makes the mesh plate 14 and the unclogging needle 42 close to each other, effectively improving the unclogging effect of the unclogging needle 42 on the mesh plate 14. When the extrusion block 51 no longer squeezes the support rod 53, the support rod 53 drives the second slider 510 to reset, and the second slider 510 no longer pulls the first slider 58 through the traction rope 512, and the mesh plate 14 automatically moves upward. This cycle is repeated, so that the mesh plate 14 can continuously reciprocate up and down. On the one hand, it can ensure the unclogging effect of the unclogging needle 42 on the mesh holes, and on the other hand, it can drive the raw materials above the mesh plate 14 to shake continuously, thereby improving the feeding rate.
[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
