Abstract
Description
Technical Field
[0001] This application belongs to the field of brewing equipment technology, and in particular relates to a mixing device to prevent spillage. Background Technology
[0002] With the increasing automation of industrial production, a large number of mechanical devices have been used in brewing processes to replace manual operations, greatly improving production efficiency. Mixing equipment is typically used to replace manual labor when mixing materials such as mash, grains, and bran.
[0003] Existing mixing devices typically involve adding various materials to an open hopper according to a set ratio, then connecting and securing the hopper to a downward-facing mixing chamber. The hopper and mixing chamber are then rotated 180° as a whole, with the hopper on top and the mixing chamber below. This allows the material in the hopper to be poured into the mixing chamber, where its mixing mechanism can then be used for mixing. After thorough mixing, the hopper and mixing chamber are rotated 180° again, and the mixed material is poured back into the hopper. Finally, the hopper is separated from the mixing chamber, allowing it to be transported along with its contents to the next process. The hopper not only allows for material turnover but also seals the mixing chamber opening during mixing. However, the mixing chamber is only open during mixing; otherwise, it remains open downwards. This can cause residual material to spill down the sides, especially in square-shaped mixing chambers where material at the corners is difficult to empty and tends to remain. Subsequent spillage, whether due to natural falling or equipment vibration, outside the mixing chamber not only wastes raw materials but also worsens the working environment, increases the difficulty of cleaning, and the spilled material can affect the normal operation of surrounding equipment, greatly increasing the equipment failure rate. Utility Model Content
[0004] To address the technical problem of residual materials easily spilling from the mixing chamber in existing technologies, this application provides a spill-proof mixing device.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is a spillage prevention mixing device, comprising: The mixing chamber is open at one end and is rotatably mounted on the mounting frame. A tilting mechanism, mounted on the mounting frame, is used to drive the mixing chamber to tilt on the mounting frame; A hopper is used to load materials. A conveying mechanism for conveying the material box; A lifting mechanism is located below the mixing chamber and connected to the conveying mechanism, used to drive the conveying mechanism to rise or fall; A locking mechanism, fixed to the mixing chamber, is used to lock the material box and the mixing chamber together; When the lifting mechanism is at its lower limit of travel, the distance between the lowest position of the mixing chamber on its flipping trajectory and the conveying mechanism is greater than the height of the material box.
[0006] In some embodiments, the inner wall of the closed end of the mixing chamber has an arc-shaped structure, and the inner cavity is provided with a mixing shaft and a mixing paddle mounted on the mixing shaft. A power mechanism is provided on the outer wall of the mixing chamber, and the power mechanism is drivenly connected to the mixing shaft.
[0007] In some embodiments, the stirring paddle includes a connecting rod and stirring blades. One end of the connecting rod is connected to the stirring shaft, and the other end is connected to the stirring blades. The stirring blades are inclined on the connecting rod, and the stirring blades on both sides of the midpoint of the stirring shaft are inclined in opposite directions.
[0008] In some embodiments, the flipping mechanism includes a drive motor fixed on the mounting frame and a slewing bearing that is drively connected to the drive motor. The slewing bearing is connected to a rotating shaft at one end of the mixing chamber, and the rotating shaft at the other end of the mixing chamber is rotatably mounted on the mounting frame.
[0009] In some embodiments, the conveying mechanism includes a support, a sprocket, a conveying chain, and a conveying motor. The sprocket is mounted on the support, the conveying chain is mounted on the sprocket, the conveying motor is connected to the sprocket via a drive, and the support is connected to the lifting mechanism.
[0010] In some embodiments, the lifting mechanism includes a lifting motor mounted on the mounting frame and a plurality of worm gear screw jacks that are drively connected to the lifting motor. The plurality of worm gear screw jacks are distributed on both sides of the bracket, and the bracket is provided with ear plates that are fixedly connected to the lifting nuts on the worm gear screw jacks.
[0011] In some embodiments, the support is covered with a baffle.
[0012] In some embodiments, the locking mechanism includes clamping cylinders slidably disposed at both ends of the mixing chamber, a clamping plate disposed at the output end of the clamping cylinders, and an adjusting mechanism for adjusting the relative position of the clamping cylinders.
[0013] In some embodiments, the adjustment mechanism includes an adjustment motor fixed on the mixing chamber and an adjustment screw that is drivenly connected to the adjustment motor, and the clamping cylinder is connected to the adjustment nut on the adjustment screw.

Beneficial effects
[0015] This application employs a special design that increases the distance between the mixing chamber and the conveying mechanism. Even when the conveying mechanism is at its lowest position, there is still a certain height space between the mixing chamber and the material box, which does not affect the normal rotation of the mixing chamber. Before the material box is moved horizontally out of the conveying mechanism, the mixing chamber can be rotated to an open-facing position to prevent material from spilling onto the outside of the material box. This helps to avoid waste of raw materials, improves the cleanliness of the working environment, reduces cleaning difficulty, and also facilitates the effective operation of the equipment.
[0016] In this application, the conveying mechanism uses a lifting motor to drive multiple worm gear screw lifts to lift synchronously, ensuring safety and equipment stability, facilitating simultaneous contact between the edges of the material box and the mixing chamber, preventing skewing, ensuring a sealing effect and preventing spillage when materials are overturned.

[0019] The present application will be further described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without making creative changes are within the protection scope of the present application.
[0020] As shown in Figures 1 and 2, the anti-spillage mixing device provided in this application includes: a mixing chamber 1 with one open end, rotatably mounted on a mounting frame 2; a tilting mechanism 7 installed on the mounting frame 2 to drive the mixing chamber 1 to tilt on the mounting frame 2; a material box 3 serving as a container for loading and circulating materials; a conveying mechanism 4 conveying the material box 3 to the bottom of the mixing chamber 1; a lifting mechanism 5 connected to the bottom of the conveying mechanism 4, located below the mixing chamber 1, to raise or lower the conveying mechanism 4 and its material box 3, so that the material box 3 can dock with or separate from the mixing chamber 1; a locking mechanism 6 is also provided on the mixing chamber 1, which can lock and fix the material box 3 and the mixing chamber 1 together when the material box 3 rises and docks with the opening of the mixing chamber 1. Figure 2 As shown, when the lifting mechanism 5 is at its lower limit of travel, the mixing chamber 1 is on its tilting trajectory ( Figure 2 The distance H between the lowest position on the trajectory shown by the dashed line and the conveying mechanism 4 is greater than the height h of the material box 3.
[0021] The specific operation process is as follows: If there is no material box 3 on the conveying mechanism 4, the mixing chamber 1 is in the initial state with the opening facing upwards, the lifting mechanism 5 is at the lower limit of its stroke, and the conveying mechanism 4 is in the lowest position. When the material box 3 containing the material enters the conveying mechanism 4, since the distance between the conveying mechanism 4 and the mixing chamber 1 is greater than the height of the material box 3, the conveying mechanism 4 can smoothly convey the material box 3 to the bottom of the mixing chamber 1 without causing interference. After the material box 3 is conveyed to the designated position by the conveying mechanism 4, the tilting mechanism 7 drives the mixing chamber 1 to tilt 180°, so that the opening of the mixing chamber 1 faces downwards. At this time, even if there is still residual material in the mixing chamber 1, it will fall into the material box 3 and will not spill out, until it rotates to correspond with the upper end of the material box 3. During this process, since the distance between the lowest position of the mixing chamber 1 on its tilting trajectory and the conveying mechanism 4 is greater than the height of the material box 3, the tilting action of the mixing chamber 1 will not be interfered with by the material box 3. The lifting mechanism 5 then drives the conveying mechanism 4 carrying the material box 3 to rise, so that the material box 3 rises until its upper end abuts against the opening of the mixing chamber 1. The locking mechanism 6 then locks the material box 3 and the mixing chamber 1 together. After locking, the lifting mechanism 5 drives the conveying mechanism 4 to descend to its lower limit of travel, and the material box 3 is suspended at the bottom of the mixing chamber 1. At this time, the tilting mechanism 7 drives the mixing chamber 1 and the material box 3 to rotate 180° as a whole. The material box 3 is then tilted above the mixing chamber 1, and the material in the material box 3 is poured into the mixing chamber 1 for mixing. After mixing is complete, the tilting mechanism 7 rotates the mixing chamber 1 and the material box 3 180° to their original positions, placing the material box 3 below the mixing chamber 1. The material is then poured back into the material box 3. At this time, the lifting mechanism 5 raises the conveying mechanism 4 to catch the material box 3. After the locking mechanism 6 unlocks, the lifting mechanism 5 lowers the conveying mechanism 4, separating the material box 3 from the mixing chamber 1. The opening of the mixing chamber 1 then faces downwards, and any remaining material falls into the material box 3 below. When the lifting mechanism 5 lowers the conveying mechanism 4 and the material box 3 to its lower limit, the tilting mechanism 7 rotates the mixing chamber 1 180° again, making its opening face upwards. After this, even if the material box 3 is conveyed away from below the mixing chamber 1 by the conveying mechanism 4, the remaining material inside will not spill out. Throughout the process, the mixing chamber 1 is always under the material box 3 during the tilting process and when the opening is facing downwards. Before the material box 3 is removed from under the mixing chamber 1, the tilting mechanism 7 tilts the mixing chamber 1 to the position with the opening facing upwards. During the entire process, the material in the mixing chamber 1 will not spill into the working environment, which not only improves the cleanliness of the environment and reduces the difficulty of cleaning, but also avoids the impact of spilled material on the normal operation of the equipment.
[0022] like Figure 3 , Figure 5 and Figure 6As shown, to facilitate uniform mixing of materials, the inner wall of the closed end of the mixing chamber 1 has an arc-shaped structure. The inner cavity is equipped with a stirring shaft 13 and a stirring paddle mounted on the stirring shaft 13. A power mechanism 11 is installed on the outer wall of the mixing chamber 1, and the power mechanism 11 is connected to the stirring shaft 13. The stirring shaft 13 and its stirring paddle can be used to stir the materials in the mixing chamber 1, ensuring uniform mixing of various materials. Setting the inner wall of the closed end of the mixing chamber 1 as an arc-shaped structure, whose shape matches the running trajectory of the stirring paddle, not only effectively reduces dead zones in the mixing process, facilitating thorough mixing of materials, but also ensures that the center of gravity of the materials and the plane containing the axis of the mixing chamber 1 remain stable near the vertical plane during the mixing process, which is beneficial to the stability of the equipment and avoids instability caused by the shift of the material's center of gravity. Furthermore, it reduces the number of corners on the inner wall of the mixing chamber 1, effectively reducing the amount of material accumulating at the internal corners when the opening of the mixing chamber 1 faces downwards.
[0023] Specifically, in order to further improve the mixing effect, such as Figure 6 As shown, in some embodiments, the stirring paddle includes a connecting rod 14 and stirring blades 15. One end of the connecting rod 14 is connected to the stirring shaft 13, and the other end is connected to the stirring blades 15. The stirring blades 15 are inclinedly arranged on the connecting rod 14, and the stirring blades 15 on both sides of the midpoint of the stirring shaft 13 are inclined in opposite directions. When the power mechanism 11 drives the stirring shaft 13 to rotate, due to the inclined arrangement of the stirring blades 15, the material can be axially propelled and conveyed while stirring. Since the stirring blades 15 on both sides are inclined in opposite directions, the power mechanism 11 controls the stirring shaft 13 to rotate alternately in both directions. While the material is being turned over, it also has an alternating process of being conveyed from both sides to the center and then from the center to both sides, making the material in the mixing chamber 1 more evenly mixed.
[0024] Furthermore, such as Figure 5 As shown, the tilting mechanism 7 includes a drive motor 72 fixed on the mounting frame 2 and a slewing bearing 71 that is drive-connected to the drive motor 72. The slewing bearing 71 is connected to a rotating shaft 12 at one end of the mixing chamber 1, and the rotating shaft 12 at the other end of the mixing chamber 1 is rotatably mounted on the mounting frame 2. Specifically, the drive motor 72 is drive-connected to the slewing bearing 71 through a reducer. The slewing bearing 71 can simultaneously withstand large axial and radial loads and overturning moments, thus meeting the requirements for tilting the mixing chamber 1.
[0025] like Figure 7As shown, in some embodiments, the conveying mechanism 4 includes a bracket 41, a sprocket 42, a conveying chain 43, and a conveying motor 44. The sprocket 42 and the conveying motor 44 are mounted on the bracket 41, the conveying chain 43 is mounted on the sprocket 42, and the conveying motor 44 is drively connected to the sprocket 42. The bracket 41 is connected to the lifting mechanism 5. The conveying motor 44 drives the sprocket 42 to rotate, which in turn drives the conveying chain 43, thereby conveying the material box 3. Figure 1 As shown, the support 41, as the main body of the conveying mechanism 4, is connected to the lifting mechanism 5. When the lifting mechanism 5 lifts or lowers, it can drive the conveying mechanism 4 and its upper material box 3 to lift or lower as a whole. Compared with lifting the material box 3 separately, the lifting mechanism 5 drives the conveying mechanism 4 and the material box 3 to lift or lower as a whole, and the lifting process is more stable.
[0026] like Figure 3 As shown, in some embodiments, the lifting mechanism 5 includes a lifting motor 51 mounted on the mounting frame 2 and a plurality of worm gear screw jacks 52 that are driveably connected to the lifting motor 51. The plurality of worm gear screw jacks 52 are distributed on both sides of the bracket 41, and the bracket 41 is provided with ear plates 46 that are fixedly connected to the lifting nuts 54 on the worm gear screw jacks 52. Specifically, as Figure 1 and 3 As shown, the lifting motor 51 is fixedly installed on one side of the bottom of the mounting frame 2, and a steering box 8 with two output ends is connected to its output end. A worm gear screw jack 52 is fixedly installed on the mounting frame 2 on both sides of the bottom of the bracket 41, resulting in four worm gear screw jacks 52. The upper end of the screw of each worm gear screw jack 52 is rotatably mounted on the mounting frame 2. Two worm gear screw jacks 52 located on the same side as the lifting motor 51 are connected to the two output shafts of the steering box 8 via transmission rods 53. The other two worm gear screw jacks 52 are connected to the corresponding worm gear screw jacks 52 located on the same end via transmission rods 53. When the lifting motor 51 rotates, it drives the four worm gear screw jacks 52 to operate synchronously. The rotation of the screws of the worm gear screw jacks 52 causes the conveying mechanism 4, which is fixedly connected to its lifting nut 54, to rise. The synchronous operation of the worm gear screw jacks 52 ensures the synchronicity and stability of the lifting of the conveying mechanism 4 and the material box 3, facilitating simultaneous contact between the edges of the material box 3 and the mixing chamber 1 and preventing skewing.
[0027] like Figure 7 As shown, preferably, the support 41 is covered with a baffle 45. The baffle 45 prevents materials from spilling onto the equipment below the conveying mechanism 4 during the transfer process.
[0028] like Figures 3-5As shown, the locking mechanism 6 further includes clamping cylinders 61 slidably disposed at both ends of the mixing chamber 1, clamping plates 63 disposed at the output ends of the clamping cylinders 61, and an adjustment mechanism for adjusting the relative positions of the clamping cylinders 61. The adjustment mechanism allows the clamping cylinders 61 and their clamping plates 63 to move away from the mixing chamber 1, thereby avoiding interference during the process of the material box 3 rising to dock with the mixing chamber 1 and falling to separate from the mixing chamber 1. After the material box 3 docks with the mixing chamber 1, the adjustment mechanism moves the clamping cylinders 61 and their clamping plates 63 closer to the mixing chamber 1. The clamping cylinders 61 drive the clamping plates 63 to rise and abut against the flange of the material box 3, thereby fixing the material box 3 to the open end of the mixing chamber 1. To improve the stability of the locking, clamping cylinders 61 are provided on both sides of both ends of the mixing chamber 1, that is, four clamping cylinders 61 are provided. At the same time, two sets of adjustment mechanisms are provided, each set of adjustment mechanisms adjusting the two clamping cylinders 61 on the corresponding side. To improve the sealing performance of the connection between the material box 3 and the mixing chamber 1, a sealing ring can be installed on the end face of the opening of the mixing chamber 1.
[0029] like Figures 3-5 As shown, specifically, to facilitate the adjustment of the position of the clamping cylinder 61, the adjustment mechanism includes an adjustment motor 62 fixed on the mixing chamber 1 and an adjustment screw 64 driven by the adjustment motor 62. The clamping cylinder 61 is connected to the adjustment nut 67 on the adjustment screw 64. Furthermore, to enable one adjustment motor 62 to simultaneously adjust two clamping cylinders 61 on its corresponding side, a steering box 8 with two output ends is provided at the output end of the adjustment motor 62. The two output ends of the steering box 8 are respectively connected to the two corresponding adjustment screws 64. Rotation of the adjustment motor 62 drives the two corresponding clamping cylinders 61 to move relative to the mixing chamber 1, ensuring good synchronization and keeping the mixing chamber 1 in a centered position.
[0030] like Figure 3 and 4 As shown, to facilitate the movement of the clamping cylinder 61, fixed frames 65 are provided at both ends of the mixing chamber 1. Slide rails 651 are provided on the fixed frames 65, and a movable frame 66 is slidably mounted on the slide rails 651. The clamping cylinder 61 is fixedly mounted on the movable frame 66, and the movable frame 66 is fixedly connected to the adjusting nut 67. When the adjusting motor 62 rotates, it drives the movable frame 66 to slide on the slide rails 651 of the fixed frame 65, thereby moving the clamping cylinder 61 and making the adjustment smoother.
[0031] While the disclosure is as stated above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the scope of protection of this application.
