Description

Technical Field

[0001] This utility model relates to the field of probiotic food mixing technology, and specifically discloses a probiotic food mixing device. Background Technology

[0002] Probiotic foods refer to functional foods containing live probiotics (such as Lactobacillus and Bifidobacterium) to improve human health by regulating the balance of intestinal flora, enhancing immunity, and promoting nutrient absorption. During their production, the freeze-dried probiotic powder must be thoroughly mixed with solid carriers (starch, maltodextrin, etc.), vitamins, and mineral excipients to ensure uniform distribution of live bacteria and product stability.

[0003] In existing technologies, the double-helix mixing structure is widely used in the field of probiotic raw material mixing. This structure uses two helical blades rotating in opposite directions to create a three-dimensional convection motion of the material within the mixing chamber, significantly improving the mixing uniformity.

[0004] However, many devices adopt a top-opening design. When the double counter-rotating spirals rotate at high speed, the material is easily thrown out of the bin by centrifugal force and eddy current, causing waste of raw materials and environmental pollution.

[0005] In addition, existing equipment usually has a discharge hole in the middle of the bottom side of the hopper, and uses a sealing plate structure to block the material. When discharging, the sealing plate needs to be removed. The material is pushed by the double spiral rotation and plays an auxiliary role in discharging. However, due to the difference in spatial layout of the inner and outer spirals, when the material height is lower than the inner spiral, the outer spiral continues to push the material in one direction, while the inner spiral, due to its higher position, cannot effectively cover the bottom residual area, causing the material to form a dead corner at the bottom edge of the hopper, making it difficult to empty the raw material.

[0006] Therefore, a probiotic food mixing device is needed to solve the above problems. Utility Model Content

[0007] This invention proposes a probiotic food mixing device that blocks the material throwing path, prevents raw materials from being thrown out of the mixing chamber, and avoids raw material waste and environmental pollution; at the same time, by flipping the mixing chamber, the material is completely removed from the mixing chamber under the action of gravity, thereby ensuring that the raw materials are emptied.

[0008] This utility model is implemented as follows: a probiotic food mixing device includes a box with an open upper side, a mixing chamber inside the box, a main shaft rotatably connected between the left and right sides of the inner wall of the box, sealed bearings fixedly connected through both ends of the mixing chamber, the main shaft fixedly connected to the inner wall of the two sealed bearings, a first helical blade on the outside of the main shaft, a second helical blade on the outside of the first helical blade, a gear ring fixedly connected to the right end of the mixing chamber located outside the main shaft, a rotating shaft rotatably connected to the right end of the inner wall of the box, a gear fixedly connected to the left end of the rotating shaft and meshing with the gear ring, and a drive mechanism on the right side of the rotating shaft.

[0009] A rectangular discharge pipe is fixedly connected through the lower end of the box, and a guide frame with a conical inner wall and communicating with the rectangular discharge pipe is fixedly connected inside the box.

[0010] A baffle is fixedly connected to the upper side inside the mixing chamber. A steering column is rotatably connected to the upper end of the baffle. A steering plate is fixedly connected to the upper end of the steering column. A screw is threaded through the upper end of the steering plate. A sealing plate is rotatably connected to the lower end of the screw. A pressure frame that abuts against the lower end of the sealing plate is fixedly connected to the upper end of the baffle and the upper end of the mixing chamber. A positioning frame located outside the sealing plate is fixedly connected to the upper end of the baffle and the upper end of the mixing chamber.

[0011] As a preferred embodiment of the probiotic food mixing device of this utility model, the driving mechanism includes a driving frame fixedly connected to the right end of the housing, a worm gear rotatably connected inside the driving frame, a worm wheel meshing with the outer wall of the worm gear, a transmission shaft fixedly connected between the worm wheel and the rotating shaft, and a servo motor whose output end is fixedly connected to the worm gear mounted on the outer wall of the driving frame.

[0012] As a preferred embodiment of the probiotic food mixing equipment of this utility model, the outer wall of the box is equipped with a drive motor whose output end is fixedly connected to the main shaft.

[0013] As a preferred embodiment of the probiotic food mixing equipment of this utility model, the upper end of the sealing plate is fixedly connected to two sliding rods that penetrate the steering plate and are slidably connected to the steering plate.

[0014] In a preferred embodiment of the probiotic food mixing equipment of this utility model, the lower end surface of the baffle is an inclined surface.

[0015] As a preferred embodiment of the probiotic food mixing equipment of this utility model, the left and right ends of the box are fixedly connected to the fixing frame, and the upper end of the left fixing frame is fixedly connected to the vertical plate. The left end of the vertical plate is equipped with an operation panel and a controller.

[0016] As a preferred embodiment of the probiotic food mixing equipment of this utility model, multiple fixing rods are fixedly connected between the main shaft and the first spiral blade, and between the main shaft and the second spiral blade.

[0017] The beneficial effects of this utility model are:

[0018] 1. After the raw materials are poured in through the gap between the baffle and the inner wall of the mixing chamber, rotate the steering plate to move the sealing plate above the positioning frame, and tighten the screw to press the sealing plate into the positioning frame and make it tightly abut against the pressure frame. Through the cooperation of the baffle and the sealing plate, the path of material throwing can be blocked, preventing the raw materials from being thrown out of the mixing chamber during the mixing process, thus avoiding material waste and environmental pollution.

[0019] 2. After mixing is complete, the sealing plate is lifted and rotated away from the pressure frame, then lowered to abut against the upper part of the baffle to open the top of the mixing chamber. Subsequently, the drive mechanism rotates the mixing chamber 180 degrees around the main shaft via gears and a gear ring. The material falls under gravity, is guided and converged by the inclined surface of the baffle and the conical guide frame, and finally discharged from the rectangular discharge pipe. By tilting the mixing chamber, the material is completely removed from the mixing chamber under gravity, thus ensuring that the raw materials are emptied and avoiding residue.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0028] Please see Figure 1-5 A probiotic food mixing device includes a box 1 with an open upper side, a mixing chamber 2 inside the box 1, a main shaft 4 rotatably connected between the left and right sides of the inner wall of the box 1, sealed bearings 3 fixedly connected through both ends of the mixing chamber 2, the main shaft 4 fixedly connected to the inner wall of the two sealed bearings 3, a first spiral blade 5 outside the main shaft 4, a second spiral blade 6 outside the first spiral blade 5, a gear ring 8 fixedly connected to the right end of the mixing chamber 2 located outside the main shaft 4, a rotating shaft 10 rotatably connected to the right end of the inner wall of the box 1, a gear 9 fixedly connected to the left end of the rotating shaft 10 and meshing with the gear ring 8, and a drive mechanism located to the right of the rotating shaft 10.

[0029] A rectangular discharge pipe 25 is fixedly connected to the lower end of the box body 1, and a guide frame 26 with a conical inner wall and connected to the rectangular discharge pipe 25 is fixedly connected inside the box body 1.

[0030] A baffle 17 is fixedly connected to the upper side inside the mixing chamber 2. A steering column 18 is rotatably connected to the upper end of the baffle 17. A steering plate 20 is fixedly connected to the upper end of the steering column 18. A screw 21 is threadedly connected to the upper end of the steering plate 20. A sealing plate 22 is rotatably connected to the lower end of the screw 21. A pressure frame 19 that abuts against the lower end of the sealing plate 22 is fixedly connected to the upper end of the baffle 17 and the upper end of the mixing chamber 2. A positioning frame 23 located outside the sealing plate 22 is fixedly connected to the upper end of the baffle 17 and the upper end of the mixing chamber 2.

[0031] In this embodiment: During use, the raw material is poured into the mixing chamber 2 through the gap between the baffle 17 and the right end of the inner wall of the mixing chamber 2. After feeding is completed, the steering plate 20 rotates with the steering column 18, which in turn drives the screw 21 and the sealing plate 22 to rotate synchronously, rotating the sealing plate 22 to the top of the positioning frame 23. Then, the screw 21 is turned by the handwheel at the top of the screw 21, causing the sealing plate 22 to move downward until the sealing plate 22 enters the positioning frame 23 and is tightly abutted against the pressure frame 19. The positioning frame 23 limits the sealing plate 22. Thus, the cooperation between the baffle 17 and the sealing plate 22 can block the material throwing path, preventing the raw material from being thrown out of the mixing chamber 2 during the mixing process, thus avoiding material waste and environmental pollution.

[0032] The main shaft 4 is fixed to the inner wall of the housing 1 by the sealed bearings 3 at both ends to ensure stability and sealing during rotation. When the main shaft 4 rotates, it drives the first spiral blade 5 and the second spiral blade 6 to rotate synchronously through the fixed rod. The spiral directions of the first spiral blade 5 and the second spiral blade 6 are opposite, forming a double anti-spiral structure. When the two rotate at the same time, the first spiral blade 5 pushes the material to one side axially, and the second spiral blade 6 pushes the material to the other side axially. At the same time, the radial centrifugal force causes the material to generate convective motion, and finally forms a three-dimensional stirring effect in the mixing chamber 2, so that the probiotic raw materials and other solid excipients are fully mixed and the uniformity is improved.

[0033] After mixing, screw 21 is turned in the opposite direction to move the sealing plate 22 upward and away from the pressure frame 19. Then, turn the steering plate 20 to drive the sealing plate 22 to rotate 180 degrees with the steering column 18. Then turn screw 21 to move the sealing plate 22 downward and abut against the upper end of the baffle 17. At this time, the upper opening of the mixing chamber 2 is opened to prepare for discharge.

[0034] The drive mechanism then drives the rotating shaft 10 to rotate, and the gear 9 at the left end of the rotating shaft 10 rotates accordingly, driving the gear ring 8 to rotate. The gear ring 8 is fixed to the right end of the mixing chamber 2, thus driving the mixing chamber 2 to rotate 180 degrees around the main shaft 4. When the mixing chamber 2 rotates, the material falls under the action of gravity, and at the same time, the inclined structure of the baffle 17 guides the material to slide downward. The material is gathered through the conical inner wall of the guide frame 26 to the rectangular discharge pipe 25, and finally discharged from the rectangular discharge pipe 25 at the lower end of the box 1. The conical design of the guide frame 26 can accelerate the flow of material, avoid residue, and ensure thorough discharge. In this way, by flipping the mixing chamber 2, the material is completely removed from the mixing chamber 2 under the action of gravity, thereby ensuring that the raw materials are emptied.

[0035] As a technical optimization of this utility model, the drive mechanism includes a drive frame 11 fixedly connected to the right end of the housing 1. A worm gear 12 is rotatably connected inside the drive frame 11. A worm wheel 13 is meshed with the outer wall of the worm gear 12. A transmission shaft is fixedly connected between the worm wheel 13 and the rotating shaft 10. A servo motor 14 with its output end fixedly connected to the worm gear 12 is installed on the outer wall of the drive frame 11.

[0036] In this embodiment: the output end of the servo motor 14 drives the worm gear 12 to rotate, the worm gear 12 meshes with the worm wheel 13, and the shaft 10 rotates through the transmission shaft. Since the worm gear 12 and the worm wheel 13 have a self-locking characteristic, the shaft 10 can be prevented from rotating when the servo motor 14 is in a non-driving state, thereby ensuring the stability of the mixing chamber 2.

[0037] As a technical optimization of this utility model, a drive motor 7 with its output end fixedly connected to the main shaft 4 is installed on the outer wall of the housing 1.

[0038] In this embodiment: the main shaft 4 is rotated by setting a drive motor 7.

[0039] As a technical optimization of this utility model, the upper end of the sealing plate 22 is fixedly connected to two sliding rods 24 that penetrate the steering plate 20 and are slidably connected to the steering plate 20.

[0040] In this embodiment: by setting two sliding rods 24, when the screw 21 is turned, the sliding rods 24 restrict the rotational freedom of the sealing plate 22, so that the sealing plate 22 only makes linear motion, thereby improving the convenience of operation.

[0041] As a technical optimization of this utility model, the lower end surface of the baffle 17 is an inclined surface.

[0042] In this embodiment: Since the lower end face of the baffle 17 is inclined, when the mixing chamber 2 rotates, the material will slide off the inclined surface of the baffle 17, thereby preventing the material from being stuck.

[0043] As a technical optimization of this utility model, the left and right ends of the box 1 are fixedly connected to the fixing frame, and the upper end of the left fixing frame is fixedly connected to the vertical plate. The left end of the vertical plate is equipped with the operation panel 16 and the controller 15.

[0044] In this embodiment: the operation panel 16 and the controller 15 constitute a human-machine interaction and automation control system. The operator sets parameters such as stirring time, double spiral speed, and mixing chamber 2 flip angle through the operation panel 16. The controller 15 accurately controls the operation of the drive motor 7 and servo motor 14 based on the PLC algorithm.

[0045] As a technical optimization of this utility model, multiple fixing rods are fixedly connected between the main shaft 4 and the first spiral blade 5, and between the main shaft 4 and the second spiral blade 6.

[0046] In this embodiment, multiple fixing rods are used to connect and fix the first helical blade 5 and the second helical blade 6 to the main shaft 4.

[0047] The working principle and usage process of this utility model are as follows: During use, the raw material is poured into the mixing chamber 2 through the gap between the baffle 17 and the right end of the inner wall of the mixing chamber 2. After the feeding is completed, the steering plate 20 rotates with the steering column 18, which in turn drives the screw 21 and the sealing plate 22 to rotate synchronously, rotating the sealing plate 22 to the top of the positioning frame 23. Then, the screw 21 is turned by the handwheel at the top of the screw 21, causing the sealing plate 22 to move downward until the sealing plate 22 enters the positioning frame 23 and is tightly abutted against the pressure frame 19. The positioning frame 23 limits the sealing plate 22. Thus, the cooperation between the baffle 17 and the sealing plate 22 can block the material throwing path, preventing the raw material from being thrown out of the mixing chamber 2 during the mixing process, thus avoiding material waste and environmental pollution.

[0048] Then, the controller 15 is sent a command through the operation panel 16, and the drive motor 7 is started by the controller 15. The output end of the drive motor 7 drives the main shaft 4 to rotate. The main shaft 4 is fixed to the inner wall of the box 1 by the sealed bearings 3 at both ends to ensure stability and sealing during rotation. When the main shaft 4 rotates, the first spiral blade 5 and the second spiral blade 6 rotate synchronously through the fixed rod. The spiral directions of the first spiral blade 5 and the second spiral blade 6 are opposite, forming a double anti-spiral structure. When the two rotate at the same time, the first spiral blade 5 pushes the material to one side axially, and the second spiral blade 6 pushes the material to the other side axially. At the same time, the radial centrifugal force causes the material to generate convective motion, and finally a three-dimensional stirring effect is formed in the mixing chamber 2, so that the probiotic raw materials and other solid excipients are fully mixed and the uniformity is improved.

[0049] After mixing, screw 21 is turned in the opposite direction to move the sealing plate 22 upward and away from the pressure frame 19. Then, turn the steering plate 20 to drive the sealing plate 22 to rotate 180 degrees with the steering column 18. Then turn screw 21 to move the sealing plate 22 downward and abut against the upper end of the baffle 17. At this time, the upper opening of the mixing chamber 2 is opened to prepare for discharge.

[0050] Then, the controller 15 is sent a command through the operation panel 16. The controller 15 controls the servo motor 14 to start. The output end of the servo motor 14 drives the worm gear 12 to rotate. The worm gear 12 meshes with the worm wheel 13, which causes the rotating shaft 10 to rotate through the transmission shaft. The gear 9 at the left end of the rotating shaft 10 rotates accordingly, and drives the gear ring 8 to rotate. The gear ring 8 is fixed to the right end of the mixing chamber 2, so the mixing chamber 2 rotates 180 degrees around the main shaft 4. When the mixing chamber 2 rotates, the material falls under the action of gravity. At the same time, the inclined structure of the baffle 17 guides the material to slide downward. The material is gathered through the conical inner wall of the guide frame 26 to the rectangular discharge pipe 25, and finally discharged from the rectangular discharge pipe 25 at the bottom of the box 1. The conical design of the guide frame 26 can accelerate the material flow, avoid residue, and ensure thorough discharge. In this way, by flipping the mixing chamber 2, the material is completely removed from the mixing chamber 2 under the action of gravity, thereby ensuring that the raw materials are emptied.
