Description

Technical Field

[0001] This utility model relates to the field of milk powder quality testing technology, and in particular to a milk powder reconstitution testing device. Background Technology

[0002] The solubility of infant formula is a crucial indicator of its quality, directly impacting infant health and the consumer experience. Poorly soluble formula is prone to producing undissolved lumps during preparation, affecting the quality of the formula and potentially even the infant's normal diet and health. Therefore, testing the solubility of formula is essential for ensuring its quality. Currently, solubility testing primarily relies on observing the state of the dissolved formula, such as the presence of white spots, white patches, clumps, or other undissolved substances. Common solubility testing methods include observing the formula after stirring and heating, and examining undissolved particles (such as protein denaturation points, white patches, and clumps) using a tilted gel plate or microscope. This testing can assess the solubility of the formula, thus reflecting its quality.

[0028] In existing technologies, the solubility testing of infant formula milk powder mainly relies on manual observation of the milk's state, which is highly subjective and inefficient. Most existing testing devices use electric cylinders to drive clamps to fix the container, but this structure suffers from complex drive components and difficulty in precisely controlling the clamping force. During the milk powder preparation and testing process, the testing container needs to withstand both centrifugal force and mechanical clamping; rigid clamping structures are prone to causing glass containers to break, affecting the accuracy of the test results.

[0029] Therefore, please refer to the following: Figure 1 and Figure 2 This application discloses a milk powder reconstitution testing device, including a base 1, a rotating component 2 rotatably disposed on the base 1, a clamping component 3 movably connected to the rotating component 2, and a driving component 4 for driving the rotating component 2. The rotating component 2 is provided with a placement groove 221 for placing a testing container. The clamping component 3 extends into the placement groove 221 and forms a clamping space with the side wall of the groove. The clamping component 3 has a built-in buffer structure 34 to provide buffering force in the clamping direction.

[0030] The buffer structure 34 refers to an elastic deformation mechanism installed inside the clamping assembly 3, which can be implemented using a spring, elastic pad, or hydraulic damper, to generate a reverse force when the clamping plate 33 contacts the container. The rotatable connection between the rotating assembly 2 and the base 1 can be achieved through a bearing or turntable 21 structure, allowing the placement slot 221 to rotate around its axis. The movable connection of the clamping assembly 3 can be achieved through a linear movement mechanism using a threaded rod and guide slide 35, allowing adjustment of the clamping distance manually or electrically. The drive assembly 4 can be a structure using a motor and reduction gears, transmitting power to the rotating assembly 2 via a rotating rod 42.

[0031] For example, after the detection container is placed in the placement slot 221 of the rotating assembly 2, the clamping assembly 3 is operated to move its clamping plate 33 toward the side wall of the detection container. When the clamping plate 33 contacts the container, the buffer structure 34 begins to compress and generate a counterforce, forming a dynamically balanced clamping state. After the driving assembly 4 is started, it drives the rotating assembly 2 to rotate. The detection container may undergo slight displacement under the action of centrifugal force. At this time, the buffer structure 34 absorbs the displacement energy through elastic deformation, avoiding rigid collision. During the rotation detection process, the buffer structure 34 continuously provides adaptive clamping force, which ensures the container is stably fixed and prevents excessive compression from causing breakage.

[0032] Understandably, this application effectively solves the problem of damage to the testing container caused by rigid clamping during dynamic rotation. The buffer structure 34 automatically compensates for container dimensional tolerances and rotational vibration, ensuring that the clamping force is always within a safe threshold. The manual adjustment mechanism of the clamping component 3 reduces equipment complexity and manufacturing costs while improving operational controllability. The synergistic effect of the rotation drive system and the buffer clamping allows the testing process to simulate real-world punching and adjusting conditions while ensuring the safety of the testing container.

[0033] Please refer to the reference. Figure 2 and Figure 3 This application further proposes that the clamping assembly 3 includes a rotating rod 31, a buffer box 32, and a clamping plate 33. The rotating rod 31 passes through the rotating assembly 2, the buffer box 32 is disposed at the end of the rotating rod 31 and located in the placement groove 221, and the clamping plate 33 is connected to the buffer box 32 through a buffer structure 34. When the rotating rod 31 moves relative to the rotating assembly 2, it drives the clamping plate 33 to move closer to or away from the side wall of the placement groove 221.

[0034] Among them, the rotating rod 31 refers to a rigid transmission component, which can be implemented as a threaded rod or a smooth shaft, and it passes through the rotating assembly 2 to form an axial displacement control channel. The buffer box 32 refers to a force transmission intermediary device, which can be implemented as a metal box or an engineering plastic shell, and its interior is equipped with a buffer structure 34 to form an elastic connection interface. The clamping plate 33 refers to the actuating component that contacts the detection container, which can be implemented as an arc-shaped metal plate or a gripper with a buffer pad, and it forms a flexible connection structure with the buffer box 32 through the buffer structure 34.

[0035] For example, the axial displacement of the rotating rod 31 is converted into the radial movement of the clamping plate 33 through threaded transmission or slide rail guidance. When the operator rotates the rotating rod 31, the buffer box 32 is pushed axially, causing the clamping plate 33 to move towards the side wall of the placement slot 221. The buffer structure 34 undergoes elastic deformation after the clamping plate 33 contacts the detection container, absorbing mechanical impact and forming a continuous clamping force. During the movement of the clamping plate 33, the compression of the buffer structure 34 increases with the increase of the clamping force. When there is a tolerance in the outer diameter of the detection container, the elastic deformation of the buffer structure 34 automatically compensates for the dimensional deviation. The displacement of the rotating rod 31 has a linear correspondence with the clamping distance, and the operator can precisely adjust the position of the clamping plate 33 by controlling the rotation angle of the rotating rod 31.

[0036] Understandably, this application achieves controllable adjustment of the container clamping force. The buffer structure 34 continuously absorbs mechanical impact during clamping, preventing container breakage caused by rigid clamping. The mechanical transmission structure of the rotating rod 31 allows the operator to intuitively control the clamping distance, and the elastic characteristics of the buffer spring 343 automatically compensate for container dimensional tolerances, ensuring reliable clamping of containers of different specifications. The linkage design between the clamping plate 33 and the buffer box 32 forms a dual protection mechanism, eliminating the risk of overload while ensuring clamping stability.

[0037] like Figure 3 As shown, this application further proposes a buffer structure 34 including a buffer plate 341, a buffer post 342, and a buffer spring 343. The buffer plate 341 is disposed inside the buffer box 32; the buffer post 342 movably passes through the buffer box 32, and one end of the buffer post 342 is connected to the buffer plate 341, and the other end is connected to the clamping plate 33; one end of the buffer spring 343 is connected to the buffer plate 341, and the other end is connected to the buffer box 32, and the buffer spring 343 is adapted to extend and retract in the moving direction of the clamping plate 33.

[0038] The buffer plate 341 is a rigid plate disposed inside the buffer box 32, which can be made of metal or engineering plastic. It is used to receive the elastic force of the buffer spring 343 and transmit it to the buffer post 342. The buffer post 342 is an axially movable rod that passes through the buffer box 32, which is used to convert the displacement of the clamping plate 33 into the linear motion of the buffer plate 341. The buffer spring 343 is an elastic element disposed along the clamping direction, which can be made of helical compression spring. Its elastic coefficient is selected according to the clamping force requirement, and it is used to absorb the impact energy generated when the clamping plate 33 comes into contact with the container.

[0039] For example, when the clamping plate 33 contacts the detection container, the axial pressure on the clamping plate 33 is transmitted to the buffer plate 341 through the buffer post 342. The buffer plate 341 compresses the buffer spring 343, causing elastic deformation. The compression stroke of the buffer spring 343 allows the clamping plate 33 to continue moving slightly along the clamping direction after contacting the container, transforming rigid clamping into elastic clamping. The through-hole design of the buffer post 342 within the buffer box 32 ensures that the force transmission direction is consistent with the clamping direction, avoiding stress concentration caused by lateral offset. The extension and retraction characteristics of the buffer spring 343 allow the clamping force to be dynamically adjusted according to changes in container size, ensuring clamping stability while avoiding exceeding the container's tolerance threshold.

[0040] Understandably, this application effectively avoids structural damage to the testing container caused by sudden changes in clamping force, ensuring uniform contact pressure for containers of different sizes during clamping, and improving the safety of the testing process. The elastic deformation characteristics of the buffer spring 343 enable the clamping force to automatically match the outer diameter of the container, achieving flexible clamping without manual intervention.

[0041] Please refer to the reference. Figure 2 and Figure 3 This application further proposes that the side of the clamping plate 33 facing away from the buffer box 32 is a concave arc structure, the side of the clamping plate 33 facing away from the buffer box 32 is provided with a first buffer pad 331, and the side wall of the placement groove 221 is provided with a second buffer pad 332.

[0042] The concave arc-shaped structure refers to the concave curved surface of the clamping plate 33 in contact with the detection container, which allows for surface contact with the outer wall of the cylindrical container. The first buffer pad 331 is an elastic material layer covering the contact surface of the clamping plate 33, which can be silicone or rubber sheets bonded together to absorb the mechanical impact generated by the clamping action. The second buffer pad 332 is an elastic material layer disposed on the side wall of the placement groove 221, used to buffer the contact vibration between the container and the placement groove 221.

[0043] For example, when the container is clamped between the clamping plate 33 and the placement groove 221, the surface of the arc-shaped clamping plate 33 forms a continuous curved surface contact with the outer wall of the container, increasing the contact area compared to planar clamping and thus reducing the pressure per unit area. The first buffer pad 331 undergoes elastic deformation during clamping by the clamping plate 33, converting the rigid clamping force into an elastic clamping force, preventing local stress from exceeding the strength of the container material. The second buffer pad 332 absorbs the vibration energy between the container and the placement groove 221 through elastic deformation when the container rotates with the turntable 21, preventing direct collision between the container sidewall and the metal groove. This technical solution maintains a stable clamping state under dynamic rotation conditions through the synergistic effect of structural adaptation and buffer materials.

[0044] This application further proposes a buffer structure 34 including at least two buffer pillars 342, the at least two buffer pillars 342 being spaced apart along the length direction of the buffer plate 341; the buffer structure 34 includes a plurality of buffer springs 343, the plurality of buffer springs 343 being spaced apart along the length direction of the buffer plate 341.

[0045] For example, when the buffer pillars 342 are spaced apart along the length of the buffer plate 341, each buffer pillar 342 independently transmits the clamping force, forming multiple support points and avoiding stress concentration caused by a single pillar. When the buffer springs 343 are spaced apart along the length, each spring independently generates elastic deformation, automatically adjusting the compression amount according to the curvature difference of the container's outer wall during clamping. When the clamping plate 33 contacts the detection container, the spaced distribution of the buffer pillars 342 disperses the pressure along the container's axial direction, and the spaced arrangement of the buffer springs 343 ensures that the elastic support force covers different areas around the container's circumference. When the container experiences slight deformation, the spaced buffer pillars 342 and springs can generate differentiated displacement compensation, preventing local overload.

[0046] Understandably, this application can distribute clamping pressure to multiple buffer support points, reducing the local stress peak on the sidewall of the testing container and preventing cracks or deformation of glass or plastic testing containers during clamping. The spaced buffer springs 343 can automatically adjust the compression amount in each area according to the curvature of the container's outer wall, ensuring that both round and irregularly shaped testing containers obtain a uniform clamping contact surface. The synergistic effect of the buffer pillars 342 and the springs creates a rigid constraint in the vertical clamping direction and maintains elastic buffering in the clamping direction, balancing clamping stability and damage protection.

[0047] This application further proposes that the clamping assembly 3 also includes a guide slide rod 35, which movably passes through the rotating assembly 2 and is arranged parallel to the rotating rod 31.

[0048] The guide slide rod 35 is a rigid rod arranged parallel to the rotating rod 31. It can be implemented using a smooth stainless steel cylindrical rod. The guide slide rod 35 passes through the rotating assembly 2 and forms a sliding pair, providing a linear sliding trajectory during the movement of the clamping assembly 3 and restricting the direction of movement of the clamping assembly 3. The parallel arrangement with the rotating rod 31 means that the rotating rod 31 and the guide slide rod 35 maintain axial consistency. This can be achieved by symmetrically installing threaded rods and guide slide rods 35 on both sides of the rotating assembly 2, forming a dual-axis constraint structure to eliminate radial offset caused by the movement of a single rotating rod 31.

[0049] For example, the guide slide rod 35 and the rotating rod 31 both pass through the rotating assembly 2. When the rotating rod 31 rotates and drives the clamping plate 33 to move, the guide slide rod 35 restricts the clamping assembly 3 to move only axially through a sliding pair. When the rotating rod 31 experiences a slight radial offset, the sliding fit between the guide slide rod 35 and the rotating assembly 2 absorbs the offset, forcing the clamping plate 33 to remain perpendicularly aligned with the side wall of the placement groove 221. This parallel double-rod structure ensures that the clamping plate 33 always translates along a predetermined trajectory during movement, avoiding clamping angle deviations caused by deformation of the rotating rod 31 under stress or assembly gaps, thereby ensuring uniform force on both sides of the testing container.

[0050] Understandably, this application effectively solves the problem of uneven clamping force distribution caused by the movement offset of the clamping component 3, ensuring that the detection container is always subjected to a uniform circumferential clamping force during rotation, avoiding container breakage or deformation due to excessive local stress, and improving the movement stability of the clamping component 3 under high-speed rotation conditions.

[0051] This application further proposes that the rotating rod 31 adopts a threaded lever structure, and a handwheel 311 is installed at the end of the rotating rod 31 away from the buffer box 32.

[0052] The threaded lever refers to a rod-shaped component with external threads, which can be made of metal to form a helical groove structure. Rotating the threaded lever drives the clamping assembly 3 to move axially. The handwheel 311 is a circular operating component installed at the end of the lever. It can be made of plastic or metal with a wheel structure with anti-slip texture. The rotation angle of the threaded lever is controlled by manually rotating the handwheel 311.

[0053] For example, the threaded lever and the rotating assembly 2 are connected by a threaded engagement. The operator rotates the handwheel 311 to drive the threaded lever, causing the clamping plate 33 to displace along the threaded axis. The mechanical characteristics of the threaded drive make the moving speed of the clamping plate 33 linearly related to the rotation angle of the handwheel 311. The operator can adjust the rotation amplitude in real time based on tactile feedback, thereby precisely controlling the contact pressure of the clamping plate 33 on the detection container. The self-locking effect generated by the threaded engagement prevents accidental displacement of the clamping assembly 3 during rotation, ensuring a stable clamping state.

[0054] Understandably, this application achieves stepless and precise adjustment of the container clamping force, avoiding the risk of container rupture due to overload or runaway of the electric drive device, while simplifying the equipment structure and reducing maintenance costs.

[0055] like Figure 4As shown, this application further proposes that the top surface of the base 1 is provided with a sliding groove 11, the rotating component 2 includes a turntable 21, the turntable 21 is connected to the driving component 4, the side of the turntable 21 facing the base 1 is provided with a slip ring 211, the slip ring 211 is slidably provided in the sliding groove 11, the cylinder 22 is provided on the turntable 21, the cylinder 22 is provided with a placement groove 221, and the clamping component 3 is movably connected to the cylinder 22.

[0056] The groove 11 refers to the groove structure on the top surface of the base 1, which can be an arc-shaped groove design, used to limit and constrain the movement trajectory of the slip ring 211. The slip ring 211 refers to the annular protrusion structure on the bottom of the turntable 21, whose outer diameter matches the inner diameter of the groove 11 to achieve a sliding fit. The turntable 21 refers to the disc-shaped component connected to the drive assembly 4, which can be fixedly connected to the output shaft of the drive assembly 4 by bolts or welding. The cylinder 22 refers to the columnar component set on the turntable 21, which can be a hollow cylindrical structure, forming a cavity space for placing the detection container.

[0057] For example, the cooperation between the slide groove 11 and the slip ring 211 allows the slip ring 211 to slide along the extension direction of the slide groove 11 when the turntable 21 rotates under the drive assembly 4, thereby limiting the horizontal offset of the turntable 21. The rigid connection between the turntable 21 and the cylinder 22 ensures that the placement slot 221 rotates synchronously with the turntable 21, avoiding the problem of asynchronous rotation caused by component separation. The movable connection between the clamping assembly 3 and the cylinder 22 allows the clamping plate 33 to move radially along the cylinder 22. Under the sliding side effect of the slip ring 211 and the slide groove 11, the rotational motion of the cylinder 22 is restricted within the planar trajectory formed by the slide groove 11, eliminating vibration caused by eccentricity during rotation.

[0058] Understandably, this application solves the problem of shaking caused by the instability of the rotating mechanism during the rotation of the testing container. At the same time, the cooperation between the slide groove 11 and the slip ring 211 simplifies the structural complexity of the rotating component 2, ensuring that the testing container maintains a fixed position under the action of centrifugal force and avoiding the impact of device vibration on the accuracy of the testing results.

[0059] This application further proposes that the base 1 is provided with a mounting groove 12, and the drive assembly 4 includes a drive component 41 and a rotating rod 42. The drive component 41 is disposed in the mounting groove 12, and one end of the rotating rod 42 is connected to the drive component 41, and the other end is connected to the side of the turntable 21 away from the cylinder 22.

[0060] The mounting groove 12 refers to the recessed structure on the base 1, which can be formed into a rectangular or circular groove by machining. Its function is to provide a fixed space for the drive component 41 and prevent displacement of the drive component 41 during operation through physical limiting. The drive component 41 refers to the power output device, which can be implemented by a geared motor or a servo motor. Its function is to transmit rotational power to the turntable 21 through the rotating rod 42, driving the turntable 21 to rotate relative to the base 1. The rotating rod 42 refers to the rigid connecting component, which can be implemented by a metal rod or a carbon fiber rod. Its function is to form a linear connection between the output end of the drive component 41 and the turntable 21, reducing power loss by eliminating intermediate transmission links.

[0061] For example, the drive component 41 is fixed in the mounting groove 12 of the base 1, and physical constraint is achieved by bolts or snap-fit ​​structures. One end of the rotating rod 42 is fixed to the output shaft of the drive component 41 via a coupling, and the other end is welded or bolted to the non-working side surface of the turntable 21. When the drive component 41 is started, the rotating rod 42 directly transmits the rotational torque to the turntable 21, driving the turntable 21 to rotate around the axis of the base 1. Since the connection position between the rotating rod 42 and the turntable 21 is located in the extension direction of the central axis of the turntable 21, the torque generated during the rotation of the turntable 21 is evenly distributed, avoiding impact on the detection container due to eccentric force.

[0062] Understandably, this application achieves a compact layout of the drive component 4, reducing the complexity of the overall device structure. At the same time, through the design of rigid connection and uniform torque distribution, it avoids the risk of damage to the detection container caused by local stress concentration.

[0063] This application further proposes that the bottom wall of the placement slot 221 is provided with a temperature sensor 223, and the side wall of the base 1 is provided with a control panel 13, which is electrically connected to the temperature sensor 223 and the drive assembly 4.

[0064] The temperature sensor 223 is a component used to detect changes in the temperature of the mixing liquid inside the container in real time. It can be implemented using a thermocouple or a resistance temperature detector (RTD) sensor, and its physical contact with the bottom wall of the placement tank 221 allows it to directly sense the temperature at the bottom of the container. The control panel 13 is an interface integrating data processing and signal transmission functions. It can be implemented using a touchscreen with a microprocessor, receiving signals from the temperature sensor 223 and generating control commands for the drive component 4. The electrical connection refers to the data transmission path established between the temperature sensor 223, the control panel 13, and the drive component 4 via wires or a wireless communication module. It can be implemented using shielded cables or a Bluetooth module to ensure the stability of signal transmission.

[0065] For example, temperature sensor 223 is embedded in the bottom wall of placement slot 221. When a change in the temperature of the mixing liquid in the container is detected, temperature sensor 223 will collect temperature data in real time and transmit it to control panel 13. The algorithm built into control panel 13 compares the temperature data with a preset threshold. If the temperature exceeds the set range, a speed adjustment signal is generated and sent to drive component 4. Drive component 4 dynamically adjusts the rotation speed of rotating component 2 according to the received signal, for example, reducing the speed when the temperature rises to avoid liquid splashing, or increasing the speed when the temperature falls to enhance the dissolving effect. This forms a closed-loop control system, realizing automatic matching of temperature and speed without manual intervention.

[0066] Understandably, this application can ensure that the temperature of the mixing solution is within the preset range, avoiding deviations in the dissolution effect caused by temperature fluctuations; by automatically adjusting the rotation speed of the rotating component 2, constant detection conditions are maintained, reducing the interference of manual operation on the detection results; the integrated design of the temperature sensor 223 and the bottom wall of the placement tank 221 improves the temperature detection accuracy, and the side wall layout of the control panel 13 optimizes the ease of operation.

[0067] In one embodiment, the working principle of this utility model is as follows: In use, first place the test beaker into the cylinder 22, then rotate the handwheel 311 to rotate the threaded lever, thereby pushing the clamping plate 33 towards the test beaker and pushing the test beaker to one side of the inner wall of the cylinder 22. The design of the two guide slide rods 35 guides the clamping plate 33. When the clamping plate 33 continuously presses against the test beaker, the buffer column 342 pushes the buffer plate 341 and squeezes the buffer spring 343. The elastic deformation of the buffer spring 343 effectively absorbs the rigid mechanical pressure transmitted by the threaded lever, preventing damage to the test beaker and allowing precise control of the clamping force. By setting up the first buffer pad 331 and the second buffer pad 332, friction is increased, providing an anti-slip effect. Simultaneously, the drive motor is activated via the control panel 13, which rotates the rotating rod 42, thereby driving the turntable 21 to rotate, causing the testing beaker to rotate. This stirs and mixes the milk powder inside the testing beaker, enabling the preparation of the milk powder. The temperature sensor 223 detects the temperature of the milk in the testing beaker and displays it on the control panel 13, facilitating real-time monitoring of the milk temperature and ensuring precise control to keep the temperature within the set range for complete dissolution of the milk powder. This design is highly adaptable, accommodating testing beakers of different sizes, and is highly practical.

[0068] After stirring is completed, the device is allowed to stand for a period of time (e.g., 300 seconds) to enable full reaction between the milk powder and water. Subsequently, an operator slowly pours all the reconstituted solution in the detection beaker onto an inclined black rubber plate, observes the solution on the black rubber plate, and checks for the presence of small white spots (protein denaturation points with a diameter R ≤ 0.5 mm), white patches (incompletely dissolved powder or flocs of denatured protein with a diameter 0.5 mm < R ≤ 3 mm) or lumps (with a diameter R > 3 mm). At the same time, the operator checks the inner wall and bottom of the detection beaker for insoluble lumps and other conditions. These undissolved substances can be used as important indicators for evaluating the solubility of milk powder for result analysis. Through these steps, the solubility of milk powder can be accurately determined, and a scientific basis is provided for quality control.

Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications or equivalent substitutions made to the technical solution of the present utility model do not depart from the spirit and scope of the technical solution of the present utility model, and shall all be covered within the scope of the claims of the present utility model.
