Description

Technical Field

[0001] This invention relates to the field of feeding device technology, and in particular to a quantitative feeding device for solid beverage raw materials. Background Technology

[0002] In the production of solid beverages, various powdered raw materials need to be mixed and blended in precise proportions. The looseness and uniformity of the raw materials directly determine the quality of the finished solid beverage. Currently available quantitative feeding and mixing equipment has significant shortcomings in actual operation. Powdered solid beverage raw materials are highly susceptible to agglomeration due to their hygroscopic properties, storage and stacking compression, and friction during transport. Traditional equipment relies solely on a single stirring structure for post-mixing, lacking a pre-mixing agglomeration breaking structure, and thus cannot effectively disperse agglomerated raw materials.

[0003] Clumped raw materials are difficult to disperse and mix fully after entering the mixing tank, which easily leads to uneven mixing and local component enrichment. This seriously affects the consistency of taste and quality of solid beverages and makes it difficult to meet the needs of large-scale, standardized, and efficient production of solid beverages. Summary of the Invention

[0004] To address the technical problem of uneven mixing of various raw materials due to raw material clumping in existing technologies, this invention provides a quantitative feeding device for solid beverage raw materials.

[0005] The present invention provides a solid beverage raw material quantitative feeding device with the following technical solution: A quantitative feeding device for solid beverage raw materials includes a mixing tank, a frame, and a quantitative feeding mechanism. Both the mixing tank and the quantitative feeding mechanism are fixedly installed on the frame. The quantitative feeding mechanism is located on the side of the mixing tank and feeds raw materials into the mixing tank. The mixing tank is equipped with a sieving mechanism, and the sieving mechanism is equipped with a crushing and mixing mechanism. The crushing and mixing mechanism crushes and mixes the raw materials in the sieving mechanism. An anti-blocking knocking mechanism is installed on the inner wall of the mixing tank at a position corresponding to the sieving mechanism. During operation, the crushing and mixing mechanism synchronously drives the anti-blocking knocking mechanism to knock on the side wall of the sieving mechanism.

[0006] By adopting the above technical solution: the raw materials in the quantitative feeding mechanism first enter the screening mechanism for screening, and at the same time, the crushing and mixing mechanism crushes the lumpy raw materials in the screening mechanism and performs preliminary mixing. The crushed raw materials pass through the screening mechanism and enter the mixing tank for deep mixing. The crushing and mixing mechanism effectively improves the uniformity of raw material mixing. The linkage knocking anti-clogging knocking mechanism can reciprocate and knock the screening mechanism in sync with the dispersing operation, effectively preventing raw materials from accumulating and clogging the filter holes of the screen, greatly improving the raw material filtration and falling efficiency, ensuring continuous and stable operation of the equipment, and improving the overall operation efficiency.

[0007] Furthermore, the quantitative feeding mechanism includes a material conveying pipe, a conveying drive motor, and a storage bin. The material conveying pipe extends obliquely upward along the height direction of the mixing tank, and the upper end of the material conveying pipe extends to the open end at the top of the mixing tank. The conveying drive motor is installed at the lower end of the material conveying pipe, and a spiral conveying rod is rotatably arranged inside the material conveying pipe along its axial direction. The drive shaft of the conveying drive motor and the spiral conveying rod form a transmission connection.

[0008] By adopting the above technical solution: the screw conveyor is driven to rotate by the conveyor drive motor, and the raw materials in the material conveying pipe are conveyed to the mixing tank.

[0009] Furthermore, an infeed connecting pipe extends upward from the lower end of the side wall of the material conveying pipe, and the infeed connecting pipe is connected to the material conveying pipe; the bottom of the storage bin is fixedly connected to the top of the infeed connecting pipe, and the infeed connecting pipe is connected to the storage bin. The upper end of the side wall of the material conveying pipe is provided with a discharge connecting pipe extending downward. The discharge connecting pipe is connected to the material conveying pipe, and the bottom of the discharge connecting pipe extends into the mixing tank and corresponds to the setting position of the screening mechanism.

[0010] By adopting the above technical solution: solid beverage raw materials are put into the storage silo, the raw materials enter the material conveying pipe through the feed connecting pipe, are conveyed upward by the screw conveyor, and finally enter the screening mechanism through the discharge connecting pipe for screening, crushing and preliminary mixing.

[0011] Furthermore, the frame includes a main frame and a side support frame. The side wall of the mixing tank extends outward and is provided with an ear seat. The ear seat is fixedly installed on the main frame. The side support frame is located on the side of the main frame. An equipment mounting frame is fixedly installed on the top of the side support frame. The conveying drive motor and the material conveying pipe are both fixedly installed on the equipment mounting frame. The bottom of the equipment mounting frame is connected to the side support frame through a weight detection sensor.

[0012] By adopting the above technical solution, the weight of the raw materials inside the quantitative feeding mechanism can be monitored in real time by setting a weight detection sensor, thereby accurately controlling the weight of raw materials added to the mixing tank by the quantitative feeding mechanism.

[0013] Furthermore, the sieving mechanism includes a screen body fixing frame and a screen mesh. A frame mounting plate is provided on the side of the screen body fixing frame. The frame mounting plate is fixedly installed on the inner wall of the mixing tank. A feed hole is opened at the bottom of the screen body fixing frame, and the screen mesh is installed on the edge of the feed hole.

[0014] By adopting the above technical solution: the raw materials in the quantitative feeding mechanism enter the screening mechanism through the discharge connecting pipe, and the screening mechanism screens the raw materials to intercept agglomerated materials. The raw materials that meet the particle size requirements pass through the screen and enter the mixing tank for mixing.

[0015] Furthermore, a mixing shaft is rotatably installed inside the mixing tank. The mixing shaft is located below the sieving mechanism, and the axis of the mixing shaft is perpendicular to the axis of the mixing tank. A mixing drive motor for driving the mixing shaft to rotate is fixedly installed on the side of the main frame. Multiple sets of mixing support arms are evenly arranged along the axial direction on the outer wall of the mixing shaft, and mixing blades are provided on the mixing support arms.

[0016] By adopting the above technical solution: when mixing the raw materials inside the mixing tank, the mixing shaft is driven to rotate by the mixing drive motor, the mixing shaft drives the mixing support arm to rotate synchronously, and the mixing support arm drives the mixing blade to rotate, so as to fully mix the raw materials inside the mixing tank.

[0017] Furthermore, the crushing and mixing mechanism includes a rotary drive disk and a crushing drive motor; a motor mounting bracket is fixedly installed on the side of the mixing tank, and a transmission gear is rotatably installed on the upper part of the motor mounting bracket; the crushing drive motor is fixedly installed on the lower part of the motor mounting bracket, and the transmission shaft of the crushing drive motor and the transmission gear form a transmission connection; the rotary drive disk is slidably installed on the top of the mixing tank. A limiting component is fixedly installed on the side of the mixing tank. The limiting component includes a limiting fixing plate and a limiting connecting plate disposed on the top of the limiting fixing plate. The limiting connecting plate is slidably connected to the rotary drive disk. The edge of the rotary drive disk is provided with a tooth structure that cooperates with the transmission gear.

[0018] By adopting the above technical solution: the rotary drive disc is slidably set between the limiting connecting plate and the mixing tank, and the vertical installation position of the rotary drive disc is limited by the limiting connecting plate; in use, the crushing drive motor drives the transmission gear to rotate, and the transmission gear can drive the rotary drive disc to rotate at the top of the mixing tank.

[0019] Furthermore, the rotary drive disk has an installation port inside, and a vertical connecting arm extends downward from the inner wall of the installation port. The vertical connecting arm extends into the inside of the screen body fixing frame, and a disintegration mounting plate is provided at the bottom of the vertical connecting arm. A crushing and disintegrating head is fixedly installed at the bottom of the disintegration mounting plate.

[0020] By adopting the above technical solution: when breaking up the agglomerated raw materials in the screening mechanism, the crushing drive motor drives the rotating drive disk to rotate through the transmission gear. The rotating drive disk drives the breaking up mounting plate to rotate on the screen surface through the vertical connecting arm. The crushing and breaking up head at the bottom of the breaking up mounting plate fully contacts the agglomerated raw materials on the screen surface, breaking up and crushing the agglomerated raw materials, and achieving preliminary mixing of the raw materials.

[0021] Furthermore, the anti-blocking striking mechanism includes a U-shaped fixing member, a guide rod, and a striking head. The U-shaped fixing member is disposed on the side wall corresponding to the screen body fixing frame. One U-shaped side of the U-shaped fixing member is fixedly connected to the inner wall of the mixing tank, and the guide rod is slidably passed through the other U-shaped side of the U-shaped fixing member. One end of the guide rod is provided with a toggle piece, and the other end is fixedly installed with a striking head. The toggle piece is disposed between the two U-shaped sides of the U-shaped fixing member, and a spring is disposed between the striking head and the U-shaped fixing member. The spring is sleeved on the outside of the guide rod.

[0022] By adopting the above technical solution: under the elastic force of the spring, the striking head is attached to the outer wall of the screen body fixing frame.

[0023] Furthermore, a linkage arm is provided on the outside of the vertical connecting arm, and a linkage disc is provided at the bottom of the linkage arm. The linkage disc is sleeved between the screen body fixing frame and the actuating plate. Multiple actuating blocks are provided on the side of the linkage disc protruding outward, and a guide slope is provided at the connection between the actuating blocks and the linkage disc.

[0024] By adopting the above technical solution: under the guidance of the guide slope, the actuating block can push the actuating plate to move away from the fixed frame of the screen body; when the actuating block and the actuating plate are disengaged, the striking head moves quickly towards the fixed frame of the screen body under the elastic force of the spring and strikes the outer wall of the fixed frame of the screen body.

[0025] In summary, the beneficial effects of the present invention are as follows: 1. The present invention is equipped with a rotatable crushing and mixing mechanism used in conjunction with a screening mechanism, which can actively break up and crush lumps in the raw materials, and at the same time complete the initial mixing of the raw materials. This avoids the problems of lumps and agglomeration of solid beverage raw materials and uneven mixing, effectively improves the mixing quality of raw materials, and ensures the consistency of taste and quality of solid beverages. 2. This invention features a linkage-type anti-clogging striking mechanism that reciprocates and strikes the screening mechanism simultaneously with the dispersing operation. This effectively prevents raw materials from accumulating and clogging the filter holes of the screen, significantly improving the efficiency of raw material filtration and falling, ensuring continuous and stable operation of the equipment, and enhancing overall work efficiency. The striking end of the anti-clogging striking mechanism is made of rubber, which will not damage the equipment structure during the striking operation, effectively extending the service life of the equipment. At the same time, it can reduce the noise generated by mechanical striking and improve the working environment of the equipment.

[0026] 3. This invention is equipped with a weight detection sensor, which can monitor the weight of raw materials in real time, accurately control the quantitative feeding of raw materials, realize standardized and precise feeding, and adapt to the needs of large-scale and standardized production of solid beverages.

[0027] In summary, the various structures of this invention work together in a coordinated manner, integrating quantitative feeding, agglomeration and crushing, anti-blocking and drainage, and multi-layer mixing functions. The structure has strong linkage and a high degree of automation, which simplifies the raw material pretreatment and mixing process, reduces the cost of manual intervention, and improves the overall production efficiency.

By setting the weight detection sensor 8, the weight of the raw material inside the quantitative feeding mechanism 3 can be monitored in real time, thereby accurately controlling the weight of raw material added by the quantitative feeding mechanism 3 to the mixing tank 11.

[0034] Reference Figure 2 and Figure 4 As shown, the sieving mechanism 6 includes a screen body fixing frame 61 and a screen 62. A frame mounting plate 611 is welded to the side of the screen body fixing frame 61. The frame mounting plate 611 is fixed and locked to the inner wall of the mixing tank 11 by bolts. A feed hole is opened at the bottom of the screen body fixing frame 61, and the screen 62 is installed on the edge of the feed hole. The raw material in the quantitative feeding mechanism 3 enters the sieving mechanism 6 through the discharge connecting pipe 312. The sieving mechanism 6 sieves the raw material, intercepting agglomerated materials in the raw material. The raw material that meets the particle size requirements passes through the screen 62 and enters the mixing tank 11 for mixing. A mixing shaft 13 is rotatably installed inside the mixing tank 11. The mixing shaft 13 is located at the lower part of the sieving mechanism 6. The axis of the mixing shaft 13 is perpendicular to the axis of the mixing tank 11.

Multiple sets of mixing arms 14 are uniformly welded along the axial direction on the outer wall of the mixing shaft 13, and mixing blades 15 are welded on the mixing arms 14. When mixing the raw materials inside the mixing tank 11, the mixing shaft 13 is driven to rotate by the mixing drive motor 12. The mixing shaft 13 drives the mixing arms 14 to rotate synchronously, and the mixing arms 14 drive the mixing blades 15 to rotate, so as to fully mix the raw materials inside the mixing tank 11.

[0035] Reference Figure 1 and Figure 4As shown, the crushing and mixing mechanism 4 includes a rotary drive disk 41 and a crushing drive motor 42. A motor mounting bracket 16 is welded to the side of the mixing tank 11. A transmission gear 43 is rotatably mounted on the upper part of the motor mounting bracket 16. The crushing drive motor 42 is fixedly mounted to the lower part of the motor mounting bracket 16 by bolts, and the transmission shaft of the crushing drive motor 42 forms a transmission connection with the transmission gear 43. A sliding mounting opening 111 is provided on the top surface of the mixing tank 11. A slide table that mates with the sliding mounting opening 111 is provided at the bottom of the rotary drive disk 41. The slide table is slidably fitted inside the sliding mounting opening 111, allowing the rotary drive disk 41 to slide on the top of the mixing tank 11. A limiting component 5 is fixedly mounted to the side of the mixing tank 11 by bolts. The limiting component 5 includes a limiting fixing plate 51 and a limiting connecting plate 52 welded to the top of the limiting fixing plate 51. The bottom of the limiting connecting plate 52 is provided with a slider, and the top of the rotary drive disk 41 is provided with a limiting groove 411 that cooperates with the slider. The slider at the bottom of the limiting connecting plate 52 is slidably fitted into the limiting groove 411, so that the rotary drive disk 41 is slidably positioned between the limiting connecting plate 52 and the mixing tank 11. The vertical installation position of the rotary drive disk 41 is limited by the limiting connecting plate 52. The edge of the rotary drive disk 41 is provided with a toothed structure that cooperates with the transmission gear 43, so that the rotary drive disk 41 and the transmission gear 43 form a gear engagement. In use, the crushing drive motor 42 drives the transmission gear 43 to rotate, and the transmission gear 43 can drive the rotary drive disk 41 to rotate on the top of the mixing tank 11.

[0036] The rotary drive disk 41 has an internal mounting port. A vertical connecting arm 412 extends downwards and is welded to the inner wall of the mounting port. The vertical connecting arm 412 extends into the interior of the screen body fixing frame 61. A dispersing mounting plate 413 is welded to the bottom of the vertical connecting arm 412. A crushing and dispersing head 417 is fixedly installed at the bottom of the dispersing mounting plate 413 by bolts. When dispersing the agglomerated raw material in the screening mechanism 6, the crushing drive motor 42 drives the rotary drive disk 41 to rotate through the transmission gear 43. The rotary drive disk 41 drives the dispersing mounting plate 413 to rotate on the surface of the screen 62 through the vertical connecting arm 412. The crushing and dispersing head 417 at the bottom of the dispersing mounting plate 413 fully contacts the agglomerated raw material on the surface of the screen 62, dispersing and crushing the agglomerated raw material and achieving preliminary mixing of the raw material.

[0037] Reference Figure 5 and Figure 6As shown, the inner wall of the mixing tank 11 is also provided with an anti-blocking striking mechanism 7 for striking the screening mechanism 6. Under the striking action of the anti-blocking striking mechanism 7, the raw materials in the screening mechanism 6 can be prevented from clogging the screen 62, while the rate at which the raw materials in the screening mechanism 6 pass through the screen 62 and fall into the mixing tank 11 can be accelerated. The anti-blocking striking mechanism 7 includes a U-shaped fixing member 71, a guide rod 72, and a striking head 75. The U-shaped fixing member 71 is provided on the side wall of the screen body fixing frame 61. Specifically, one U-shaped side of the U-shaped fixing member 71 is fixedly connected to the inner wall of the mixing tank 11 by bolts, and the guide rod 72 is slidably passed through the other U-shaped side of the U-shaped fixing member 71. A toggle plate 73 is welded to one end of the guide rod 72, and a striking head 75 is bolted to the other end.

A spring 74 is installed between the striking head 75 and the U-shaped fixing member 71, and the spring 74 is sleeved on the outside of the guide rod 72. Under the elastic force of the spring 74, the striking head 75 is pressed against the outer wall of the screen body fixing frame 61. The striking head 75 is made of rubber, which can prevent damage to the outer wall of the screen body fixing frame 61 during the striking process and reduce the noise generated by the striking.

[0038] A linkage arm 418 is welded to the outside of the vertical connecting arm 412. A linkage disc 414 is welded to the bottom of the linkage arm 418. The linkage disc 414 is sleeved between the screen body fixing frame 61 and the actuating plate 73. Multiple actuating blocks 415 are welded outwardly to the side of the linkage disc 414. A guide slope 416 is provided at the connection between the actuating block 415 and the linkage disc 414. Under the guidance of the guide slope 416, the actuating block 415 can push the actuating plate 73 to move away from the screen body fixing frame 61. When the actuating block 415 disengages from the actuating plate 73, the striking head 75 moves rapidly towards the screen body fixing frame 61 under the elastic force of the spring 74, striking the outer wall of the screen body fixing frame 61.

[0039] In operation, this invention uses multiple quantitative feeding mechanisms 3 to quantitatively deliver different types of solid beverage raw materials to the sieving mechanism 6 inside the mixing tank 11. The crushing drive motor 42 in the crushing and mixing mechanism 4 is activated. The crushing drive motor 42 drives the rotating drive disk 41 to rotate via the transmission gear 43. The rotating drive disk 41 drives the bottom crushing and dispersing head 417 to rotate on the surface of the screen 62, dispersing the clumps of raw materials inside the screen body fixing frame 61 and performing preliminary mixing. Simultaneously, the rotating drive disk 41 rotates, driving the linkage disk 414 to rotate synchronously via the vertical connecting arm 412. The actuating block 415 on the linkage disk 414 drives the actuating plate 73 to move away from the screen body fixing frame 61, causing the striking head 75 to accumulate force. When the actuating block 415 disengages from the actuating plate 73, the striking head 75 strikes the outer wall of the screen body fixing frame 61 under the elastic force of the spring 74, accelerating the speed at which the raw materials pass through the screen 62 and fall into the mixing tank 11, while effectively preventing the screen 62 from clogging. Start the mixing drive motor 12, which drives the mixing shaft 13 to rotate. The mixing shaft 13 drives the mixing support arm 14 and the mixing blades 15 to rotate synchronously, so as to fully mix the raw materials inside the mixing tank 11.

[0040] This invention, by incorporating a sieving mechanism 6 and a crushing and mixing mechanism 4, can break up lumpy materials in the raw materials, achieving preliminary mixing and significantly improving the mixing effect of the subsequent mixing shaft 13. Furthermore, by incorporating an anti-clogging striking mechanism 7, the filtration efficiency of the sieving mechanism 6 can be effectively improved, preventing clogging of the screen 62. This invention effectively solves the problem of raw material agglomeration after entering the mixing tank 11, significantly improving the overall raw material mixing quality and operational efficiency of the device.
