Description

Technical Field

[0001] This utility model relates to the field of emulsion production technology, and more specifically, to a premixed emulsion stirring device. Background Technology

[0002] Emulsion premixing is a crucial step in emulsion polymerization, cosmetics production, and food processing, and the performance of the equipment directly determines the stability, uniformity, and process efficiency of the final product. However, existing premixing equipment suffers from significant technical bottlenecks in droplet dispersion control and material compatibility, leading to frequent problems such as stratification, agglomeration, and uneven mixing during production.

[0003] Chinese Patent (Application No.: CN201721755575.X) discloses a trough mixer, belonging to the field of material mixing technology. It includes a trough body, a base, a main shaft, and a stirring paddle. The trough body has a cavity suitable for containing materials. The base is placed below the trough body and is suitable for supporting the trough body off the ground. A drive structure is installed inside the base. The main shaft passes through the trough body and is connected to the drive structure inside the base. The stirring paddle is fixed on a section of the main shaft placed inside the trough body, suitable for stirring the materials inside the trough body. The main shaft and the trough body are rotatably connected. The trough body includes a frame plate, which is rotatably connected to the main shaft. The plate is detachably installed on the frame and is suitable for assembling with the frame to form a complete trough body. This invention can achieve the purpose of thoroughly cleaning the trough body of the trough mixer and can reduce the difficulty and material cost of maintaining the trough mixer.

[0004] However, the aforementioned traditional mixing equipment has the following problems:

[0005] 1. Motion dimension deficiency: It only has rotational motion around a single axis, which results in a long time required for batch mixing;

[0006] 2. Power transmission defects: The single drive source distributes torque through the reduction gearbox. When the load changes suddenly, it is easy to cause resonance in the transmission chain (increasing the failure rate). In addition, a reversing mechanism is required for reverse rotation.

[0007] 3. Insufficient process flexibility: Existing equipment parameters are too highly coupled, with parameters such as rotational speed, temperature, and shear rate exhibiting rigid correlations. For example, when switching between different APIs (active pharmaceutical ingredients) in the pharmaceutical industry, the entire set of agitators must be replaced and process parameters re-verified, reducing equipment utilization to 45%. The fixed S-shaped blades and 3-5mm bottom clearance of the trough mixer in CN201721755575.X further amplify this problem. Utility Model Content

[0008] Based on this, in order to solve the problems of traditional mixing equipment: 1. defects in motion dimension; 2. defects in power transmission; 3. insufficient process flexibility, this utility model provides a premixed emulsion stirring device, the specific technical solution of which is as follows:

[0009] A premixed emulsion stirring device, comprising:

[0010] A three-dimensional motion device, comprising a drive shaft, a driven shaft, a first rocker arm, and a second rocker arm, wherein the drive shaft is hinged to the first rocker arm, and the driven shaft is hinged to the second rocker arm;

[0011] A rotating device, which is hinged to the first rocker arm and the second rocker arm respectively;

[0012] A mixing cylinder is connected to the moving end of the rotating device, which drives the mixing cylinder to rotate.

[0013] A driving device, the output end of which is connected to the drive shaft and the driven shaft respectively, is used to drive the drive shaft and the driven shaft to rotate. The drive shaft and the driven shaft rotate in opposite directions. The three-dimensional motion device cooperates with the driving device to drive the mixing cylinder to perform the following composite motion synchronously in three-dimensional space: rotational motion around the X-axis and Y-axis, and reciprocating translational motion along the Z-axis.

[0014] The aforementioned premixed emulsion mixing equipment achieves bidirectional rotation of the mixing drum around the X and Y axes, and reciprocating translational motion along the Z axis, through the synchronous counter-rotation of the drive shaft and driven shaft via a drive device. Combined with the hinged structure of the first and second rocker arms, this allows the mixing drum to perform reciprocating translational motion along the Z axis. The rotation of the mixing drum, driven by the rotation device, creates a four-degree-of-freedom composite flow field (rotation + revolution + translation + shearing), significantly improving material turbulence intensity and eliminating mixing dead zones. The independent adjustable rotation speed (controlled by the rotation device) and three-dimensional motion frequency (controlled by the drive device) decouple the shear rate from temperature. The direct connection between the drive shaft and driven shaft eliminates the need for a reversing mechanism, achieving reverse rotation through symmetrical torque distribution. This premixed emulsion mixing equipment solves the problems of traditional mixing equipment: 1. defects in motion dimension; 2. defects in power transmission; 3. insufficient process flexibility.

[0015] Furthermore, the rotating device includes a first rotating mechanism and a second rotating mechanism, which are respectively sleeved on the outer surface of the mixing cylinder. The first rotating mechanism is hinged to the first rocker arm, and the second rotating mechanism is hinged to the second rocker arm. The first rotating mechanism and the second rotating mechanism have the same structural arrangement.

[0016] Furthermore, the first rotating mechanism includes a motion component, a first connecting block, a hinge block, and a rack with an annular outer contour; one end of the first connecting block is connected to the rack, the other end of the first connecting block is hinged to the hinge block, the hinge block is hinged to the first rocker arm, the mixing cylinder passes through the rack, the motion component is disposed on the rack and meshes with the rack, and the motion component is connected to the mixing cylinder.

[0017] Furthermore, the motion component includes a bracket, a first roller, a second roller, and a driving member.

The second roller is disposed on the bracket and rotatably connected to the bracket, and the second roller cooperates with the first roller to clamp the rack. The bracket is connected to the mixing cylinder.

[0018] Furthermore, the first roller includes a first rotating part, a gear part, and a second rotating part connected in sequence; the gear part meshes with the rack.

[0033] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0034] like Figures 1-3 As shown, a premixed emulsion stirring device according to an embodiment of the present invention includes a three-dimensional motion device 1, a rotating device 2, a mixing cylinder 3, and a driving device 4. The three-dimensional motion device 1 includes a drive shaft 11, a driven shaft 12, a first rocker arm 13, and a second rocker arm 14. The drive shaft 11 is hinged to the first rocker arm 13, and the driven shaft 12 is hinged to the second rocker arm 14. The rotating device 2 is hinged to both the first rocker arm 13 and the second rocker arm 14. The mixing cylinder 3 is connected to the moving end of the rotating device 2, and the rotating device 2 is used to drive the mixing cylinder 3 to rotate. The output end of the driving device 4 is connected to both the drive shaft 11 and the driven shaft 12, and the driving device 4 is used to drive the drive shaft 11 and the driven shaft 12 to rotate. The drive shaft 11 and the driven shaft 12 rotate in opposite directions. The three-dimensional motion device 1 and the driving device cooperate to drive the mixing cylinder 3 to synchronously perform the following composite motions in three-dimensional space: rotational motion around the X-axis and Y-axis, and reciprocating translational motion along the Z-axis.

[0035] The aforementioned premixed emulsion mixing equipment, through the synchronous counter-rotation of the drive shaft 11 and driven shaft 12 via the drive device 4, combined with the hinged structure of the first rocker arm 13 and the second rocker arm 14, enables the mixing cylinder 3 to rotate bidirectionally around the X and Y axes, while simultaneously performing reciprocating translational motion along the Z axis. The rotation of the mixing cylinder 3, driven by the rotation device 2, forms a four-degree-of-freedom composite flow field (rotation + revolution + translation + shearing) with the three-dimensional motion, significantly improving the turbulence intensity of the material and eliminating mixing dead zones. The independent adjustable rotation speed (controlled by the rotation device 2) and three-dimensional motion frequency (controlled by the drive device 4) of the mixing cylinder 3 decouples the shear rate from the temperature. The drive device 4 directly connects the drive shaft 11 and driven shaft 12, eliminating the need for a reversing mechanism, and achieving reverse rotation through symmetrical torque distribution. This premixed emulsion mixing equipment solves the problems of traditional mixing equipment: 1. defects in motion dimension; 2. defects in power transmission; 3. insufficient process flexibility.

[0036] In one embodiment, such as Figures 1-3As shown, the rotating device 2 includes a first rotating mechanism 5 and a second rotating mechanism. The first rotating mechanism 5 and the second rotating mechanism are respectively sleeved on the outer surface of the mixing cylinder 3. The first rotating mechanism 5 is hinged to the first rocker arm 13, and the second rotating mechanism is hinged to the second rocker arm 14. The first rotating mechanism 5 and the second rotating mechanism have the same structure. In this way, by symmetrically distributing the two rotating mechanisms on the outer wall of the mixing cylinder 3, the torque transmitted by the three-dimensional motion device 1 is evenly distributed to both sides of the mixing cylinder 3, avoiding eccentric vibration caused by unilateral force. When the two mechanisms drive the mixing cylinder 3 to rotate synchronously, the torque direction is dynamically adjusted through the hinge point to suppress instantaneous torque mutation caused by uneven material distribution. If one rotating mechanism fails due to overload, the other mechanism can still maintain the low-speed rotation of the mixing cylinder 3, avoiding complete shutdown of the equipment.

[0037] In one embodiment, such as Figures 1-3As shown, the first rotating mechanism 5 includes a motion component 51, a first connecting block 52, a hinge block 53, and a rack 54 with an annular outer contour. One end of the first connecting block 52 is connected to the rack 54, and the other end of the first connecting block 52 is hinged to the hinge block 53. The hinge block 53 is hinged to the first rocker arm 13. The mixing cylinder 3 passes through the rack 54. The motion component 51 is disposed on the rack 54 and meshes with the rack 54. The motion component 51 is connected to the mixing cylinder 3. The motion component 51 includes a bracket 511, a first roller 512, a second roller 513, and a driving member. The driving member is disposed on the bracket 511. The first roller 512 is disposed on the output end of the driving member, and the driving member is used to drive the first roller 512 to rotate. The second roller 513 is disposed on the bracket 511 and rotatably connected to the bracket 511. Roller 513 cooperates with the first roller 512 to clamp the rack 54; the bracket 511 is connected to the mixing cylinder 3; the first roller 512 includes a first rotating part 5121, a gear part 5122 and a second rotating part 5123 connected in sequence; the gear part 5122 meshes with the rack 54; the driving member includes a first driving block 514, a first gear 515, a second gear 516 and a first transmission rod 517; the first driving block 514 is disposed on the bracket 511, the first gear 515 is disposed on the output end of the first driving block 514, and the first driving block 514 is used to drive the first gear 515 to rotate; the first transmission rod 517 passes through the bracket 511 and is rotatably connected to the bracket 511, the first roller 512 and the second gear 516 are both sleeved on the first transmission rod 517, and the first gear 515 meshes with the second gear 516. Thus, the first roller 512 (driving wheel) is directly driven by the driving component, and the second roller 513 (driven wheel) is passively pressed against the rack 54 through the bracket 511, forming a backlash-free meshing transmission, eliminating the backlash error caused by tooth backlash in traditional gear transmission; the line contact mode between the roller and the rack 54 (compared to the point contact of gears) reduces contact stress and allows for higher loads; the double hinge structure of the first connecting block 52 and the hinge block 53 (connecting the rack 54 and the first rocker arm 13 respectively) forms a universal joint effect, compensating for the axial offset during the three-dimensional movement of the mixing cylinder 3 (such as the slight deformation of the rack 54 caused by the reciprocating translation of the Z-axis).

[0038] In one embodiment, such as Figures 1-3As shown, the emulsion mixing equipment also includes a housing; the drive device 4 is located inside the housing; the drive device 4 includes a second drive block 41, a gearbox 42, a fifth gear 43, a third gear 44, a drive gear 45, a driven gear 46, a transmission chain 47, and a fourth gear 48; the second drive block 41 is connected to the housing, the output end of the second drive block 41 is connected to the input end of the gearbox 42, and the output end of the gearbox 42 is connected to the fifth gear 43; the third gear 44 and the fourth gear 48 are both rotatably connected to the housing, the transmission chain 47 is sleeved on the drive gear 45 and the fourth gear 48, and the third gear 44 and the driven gear 46 respectively mesh with the outer surface of the rack 54; the drive gear 45 is sleeved on the drive shaft, and the driven gear 46 is sleeved on the driven shaft 12. Thus, the driving gear 45 and the driven gear 46 rotate in opposite directions, and are linked with the fourth gear 48 through the transmission chain 47 to form a closed torque loop, which counteracts the inertial torque of the single-shaft drive.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
