Description

Technical Field

[0001] This invention relates to the field of liquid preparation, specifically to a high-throughput powder and liquid preparation mechanism with weighing function. Background Technology

[0002] In existing automated batching equipment, whether for powders or liquids, the basic process typically follows: "feeding—feeding—entering the weighing container—metering feedback." Taking powder batching as an example, the feeding assembly (such as a screw conveyor, vibrating feeder, or vacuum feeding device) transports the material to the top of the weighing container. Under gravity, the material falls freely into the hopper or weighing cup. Subsequently, a weighing sensor located below the container acquires the weight signal, and the control system adjusts the feeding status based on the weighing result. Feeding stops when the preset mass value is reached, and the weighed material is then fed into the mixing or reaction unit.

[0003] Similarly, in the preparation of electrolytes or other liquid systems, the solvent is typically added quantitatively first, followed by the addition of electrolyte salts or functional additives in proportion. Liquid metering often employs weighing or flow metering, with weighing relying on the complete entry of the liquid into the weighing container to generate a valid mass signal. Dissolution and homogenization are then achieved through stirring, circulation, or a closed mixing device. This type of structure is mature and stable in conventional mass production, meeting general accuracy requirements.

[0004] However, in the traditional structures described above, the effective weighing area is typically limited to the inside of the weighing container; that is, the material must be completely inside the container and stabilized before it can be counted. For powders, at the end of the feeding stage, there may still be a certain free fall section or pipeline residue section, causing some material to continue entering the container after the control system issues a stop command, thus affecting the endpoint control. In high-precision, small-dosage, or high-throughput batching scenarios, this structural feature may place higher demands on endpoint control accuracy and batch consistency.

[0005] Furthermore, the preparation of multi-component systems such as electrolytes often involves precise control of the proportions of various powdered electrolytes or additives with liquid solvents. When there is lag in the metering of powder components or unpredictable tailings, the complexity of control compensation increases, especially under automated continuous batch operation conditions, placing higher demands on system response speed and metering stability. Therefore, related equipment structures are continuously being improved and optimized, focusing on improving the real-time performance of weighing signals, shortening unmetered paths, and optimizing force transmission structures.

[0006] In general, existing powder and liquid mixing technologies are mostly based on mature weighing container structures, and improve accuracy through control strategies and actuator adjustments. However, in some high-precision or high-throughput applications, further attention is paid to the reasonable setting of weighing boundaries and the optimization of mechanical structures to improve the timeliness of weighing feedback and overall operational stability. Summary of the Invention

[0007] This invention addresses the problem in existing powder and liquid mixing equipment where materials must be fully fed into the weighing container before being measured. This results in unmeasured mass during the free fall phase and in the residual section of the pipeline, leading to delayed response and overshoot at the feeding end, affecting weighing accuracy and batch consistency. This is particularly problematic in scenarios involving high-precision multi-component mixing such as electrolytes, where high throughput and precise control are difficult to meet. Therefore, this invention provides a high-throughput powder and liquid mixing mechanism with weighing function.

[0008] The present invention solves the above-mentioned technical problems through the following technical solutions:

[0009] The present invention provides a high-throughput powder and liquid dispensing mechanism with weighing function, including a stirring component, at least one feeding component is arranged around the stirring component, the feeding component quantitatively transports the powder into the stirring component, and the stirring component stirs and mixes the powder fed in by the feeding component and the liquid pumped in by the pump body. A weighing component is installed on one side of the bottom of the feeding component. The powder conveyed by the feeding component is conveyed to the weighing end plate through the guide plate. After weighing, the powder is pushed into the mixing component. The guide plate is located between the feeding assembly and the weighing end plate, and is set at an angle. The guide plate is fixed on the weighing end plate.

[0010] The powder conveyed by the feeding component is guided to the weighing end plate by the guide plate, and the guide plate is also fixed on the weighing end plate. That is, when the powder falls on the guide plate, it falls on the weighing end plate.

[0011] In this technical solution, the stirring assembly includes a mixing cylinder, a mounting frame is installed on the top of the mixing cylinder, a first drive motor is fixed on the mounting frame, a drive spindle is fixed on the bottom output end of the first drive motor, the bottom end of the drive spindle extends into the mixing cylinder, and stirring blades are fixed at the bottom of the drive spindle.

[0012] The first drive motor drives the main shaft to rotate the stirring blades, thereby stirring and mixing the powder and liquid inside the mixing drum.

[0013] In this technical solution, the feeding assembly includes a storage cylinder, which is fixed to the support frame by multiple rods. The top of the storage cylinder has a feeding port, and the bottom of the storage cylinder has a feeding part. The feeding section transports the powder inside the storage cylinder at an angle upwards to the discharge port, and the discharge port is located at the top of the guide plate.

[0014] The powder is fed to the weighing assembly through the upwardly inclined feeding section, and then put into the mixing drum after weighing.

[0015] The feeding section includes a feeding shell, which is inclined and the top of the feeding shell is connected to the bottom of the storage cylinder through a guide shell, and the inner cavity of the feeding shell is connected to the inner cavity of the storage cylinder through the guide shell. In this technical solution, a second drive motor is installed on the lower outer wall of the feeding shell. The output end of the second drive unit passes through the side wall of the feeding shell and is connected to the spiral feeding blade inside the feeding shell. A discharge port is provided on the bottom side wall of the higher side of the feeding shell.

[0016] The second drive motor drives the spiral feeding blades to rotate in the inner cavity of the feeding shell, thereby pushing the powder material that enters the feeding shell from the storage cylinder and the guide shell to the outlet.

[0017] The weighing assembly includes a support platform, a weighing unit is set on the top of the support platform, a weighing end plate is set on the top of the weighing unit, a weighing hopper is installed on the top of the weighing end plate, and a guide plate is fixed on the top of the weighing hopper near the discharge port. The weighing hopper is located on one side of the top of the mixing assembly; The support platform is fixed on the support frame.

[0018] In this technical solution, the bottom side of the weighing hopper is rotatably connected to the weighing end plate through a connecting part, and a push-pull member is provided on the other side of the bottom side wall of the weighing hopper. After the push-pull member extends, it pushes the weighing hopper to flip and tilt towards one side of the mixing assembly. Both sides of the weighing hopper are equipped with vibrating parts. During the hopper's rotation, the vibrating parts strike the hopper synchronously.

[0019] When the powder in the weighing hopper reaches the predetermined value, the push-pull component extends, pushing the weighing hopper to flip and put the powder into the inside of the mixing cylinder, completing the mechanized operation of feeding, weighing and dispensing, which is suitable for high-throughput batching operations.

[0020] Meanwhile, during feeding, the weighing hopper is struck by the vibrating part, which can prevent the powder from sticking to the wall.

[0021] In this technical solution, the push-pull component includes a drive rod and a mounting rod. One end of the mounting rod is fixed to the weighing end plate, and the other end is rotatably connected to one end plate of the telescopic drive rod. The other end of the drive rod is rotatably connected to the guide plate or the weighing hopper.

[0022] The drive rod is preferably one of an electric actuator or a hydraulic actuator.

[0023] The drive rod extends to push the weighing hopper to flip, thus completing the feeding process.

[0024] In this technical solution, the connecting part includes a connecting shaft, and a self-rotating connecting sleeve is sleeved on the surface of the connecting shaft. The connecting sleeve is fixed on the bottom side wall of the weighing hopper, and connecting frames are fixed at both ends of the connecting shaft. The connecting frames are fixed on the weighing end plate.

[0025] When the weighing hopper flips, the connecting sleeve rotates on the surface of the connecting shaft.

[0026] The vibrating unit includes a trigger and a vibrating element. The trigger is installed on the outer shell or support platform of the weighing unit, and the vibrating element is installed on the bottom side wall of the weighing hopper. The vibrating element rotates with the weighing hopper, and the vibrating element, while rotating, strikes the bottom of the weighing hopper after passing the trigger.

[0027] In this technical solution, the triggering element includes a fixing frame, which is installed on the outer shell or the support platform of the weighing unit. A mounting arc plate is fixed on the top of the fixing frame. The mounting arc plate is concentric with the center of the rotating hopper. Multiple triggering horizontal shafts arranged in a ring array are fixed on the mounting arc plate. As the weighing hopper tumbles, the vibrating component passes through each trigger axis in sequence.

[0028] In this technical solution, the vibrating component includes a bearing shaft. One end of the bearing shaft is fixed to the bottom side wall of the weighing hopper via an "L"-shaped connecting rod. A self-rotating sleeve is sleeved on the surface of the bearing shaft. A transmission plate that can overlap with the triggering horizontal shaft is fixed on the surface of the self-rotating sleeve. A horizontal rod that can rotate on its end is installed on one side of the transmission plate. A striking rod that overlaps with the bottom of the weighing hopper is fixed on the end of the horizontal rod. A first coil spring and a second coil spring are respectively provided at the rotatable connection between the self-rotating sleeve and the bearing shaft, and at the rotatable connection between the transverse rod and the striking rod.

[0029] The first coil spring is sleeved on the surface of the bearing shaft, and the two ends of the first coil spring are fixed to the bearing shaft and the rotating sleeve, respectively. The second coil spring is fitted onto the horizontal bar, and both ends of the second coil spring are fixed to the horizontal bar and the striking bar, respectively.

[0030] When the first and second coil springs are not deformed, the end of the striking rod overlaps the bottom side wall of the weighing hopper, and the transmission plate is located on the corresponding triggering horizontal axis side.

[0031] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of the present invention.

[0032] The positive and progressive effects of this invention are as follows: Before entering the weighing end plate, the powder conveyed by the feeding component of the present invention is guided by a guide plate. The guide plate and the weighing end plate form an integrated force-bearing structure. That is, the guide plate is fixedly installed on the weighing end plate and is in the same force transmission path as the weighing sensor. This allows the powder to transmit its gravity signal to the weighing system through the guide plate once it comes into contact with the guide plate, thereby realizing real-time measurement of the material.

[0033] Compared to existing technologies where materials are only counted after fully entering the weighing container, this solution significantly shortens the distance the powder travels in free fall by moving the effective weighing area from the container inlet to the guide plate position. This reduces uncontrollable mass increments caused by delayed material entry from the air. Consequently, the weighing feedback control logic can be triggered earlier, allowing the feeding control system to decelerate or switch to fine feeding earlier when approaching the target value. This effectively reduces the risk of overshoot caused by inertia, response delay, and pipeline residue, improving the accuracy of the final weighing.

[0034] In addition, the guide plate and the weighing end plate form an integral structure, which ensures that the powder is always in a controlled metering state during the flow process. This avoids the mass lag or lack of metering caused by the flow guiding component being independent of the weighing system in traditional material guiding structures. From a structural perspective, this ensures the uniqueness and integrity of the force path and improves the real-time performance and stability of the weighing signal. Attached Figure Description

Detailed Implementation

[0037] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments.

[0038] like Figure 1 and Figure 2 As shown, a high-throughput powder and liquid dispensing mechanism with weighing function includes a stirring component 1, and at least one feeding component 3 is arranged around the stirring component 1. The feeding component 3 quantitatively transports the powder into the stirring component 1, and the stirring component 1 stirs and mixes the powder fed in by the feeding component 3 and the liquid pumped in by the pump body. A weighing component 4 is provided on one side of the bottom of the feeding component 3. The powder conveyed by the feeding component 3 is conveyed to the weighing end plate 421 through the guide plate 44. After weighing, the powder is pushed into the mixing component 1. The guide plate 44 is located between the feeding assembly 3 and the weighing end plate 421, and is inclined. The guide plate 44 is fixed on the weighing end plate 421.

[0039] The powder conveyed by the feeding assembly 3 is guided by the guide plate 44 and then enters the weighing area (weighing end plate 421). The guide plate 44 is fixedly installed on the weighing end plate 421 and forms an integral force-bearing structure with the weighing end plate 421, so that the weight of the material borne by the guide plate 44 can be directly transmitted to the weighing end plate 421. Thus, when the powder falls onto the guide plate 44, its weight is sensed by the weighing system in real time through the weighing end plate 421, which is equivalent to the powder entering the weighing state as soon as it contacts the guide plate 44.

[0040] Through the above structural arrangement, the powder material remains within the effective weighing range throughout its transition from the feeding component 3 to the weighing end plate 421. This avoids the unmeasured free-fall section of material before entering the weighing container, as is present in traditional structures, thereby improving the timeliness of weighing feedback and enhancing the accuracy of subsequent feeding control. Simultaneously, the guide plate 44 is fixedly connected to the weighing end plate 421, ensuring a clear force transmission path, reducing metering lag or errors caused by structural separation, and improving overall weighing stability.

[0041] like Figures 12-15 As shown, the stirring assembly 1 includes a mixing cylinder 11, a mounting bracket 12 is mounted on the top of the mixing cylinder 11, a first drive motor 13 is fixed on the mounting bracket 12, a drive spindle 14 is fixed on the bottom output end of the first drive motor 13, the bottom end of the drive spindle 14 extends into the mixing cylinder 11, and a stirring blade 15 is fixed on the bottom of the drive spindle 14.

[0042] The first drive motor 13 drives the stirring blades 15 to rotate by driving the main shaft 14, thereby stirring and mixing the powder and liquid inside the mixing drum 11.

[0043] Specifically, the feeding assembly 3 includes a storage cylinder 31, which is fixed to the support frame 2 by multiple rods. The top of the storage cylinder 31 has a feeding port, and the bottom of the storage cylinder 31 has a feeding part. The feeding section transports the powder inside the storage cylinder 31 upwards at an angle to the discharge port 36, and the discharge port 36 is located at the top of the guide plate 44.

[0044] The powder is fed to the weighing assembly 4 through the upwardly inclined feeding section, and after weighing, it is put into the mixing drum 11.

[0045] The feeding section includes a feeding shell 33, which is inclined and the top of the feeding shell 33 is connected to the bottom of the storage cylinder 31 through a guide shell 32, and the inner cavity of the feeding shell 33 is connected to the inner cavity of the storage cylinder 31 through the guide shell 32. A second drive motor 34 is installed on the lower outer wall of the feeding shell 33. The output end of the second drive unit passes through the side wall of the feeding shell 33 and is connected to the spiral feeding blade 35 inside the feeding shell 33. A discharge port 36 is provided on the bottom side wall of the higher side of the feeding shell 33.

[0046] The second drive motor 34 drives the spiral feeding blades 35 to rotate in the inner cavity of the feeding shell 33, thereby pushing the powder material that enters the feeding shell 33 from the storage cylinder 31 and the guide shell 32 to the outlet.

[0047] like Figure 7-9 As shown, the weighing assembly 4 includes a support platform 41, a weighing unit 42 is provided on the top of the support platform 41, a weighing end plate 421 is provided on the top of the weighing unit 42, a weighing hopper 43 is installed on the top of the weighing end plate 421, and a guide plate 44 is fixed on the top of the weighing hopper 43 near the discharge port 36. The weighing hopper 43 is located on one side of the top of the mixing assembly 1; The support platform 41 is fixed on the support frame 2.

[0048] Preferably, the guide plate 44 is composed of multiple inclined plates, with the inclination gradually increasing from the discharge port 36 side to the weighing hopper 43 side, and the two sides of the guide plate 44 are raised to form a skirt plate 441.

[0049] The tilt angle is preferably between 60° and 65°.

[0050] Furthermore, one side of the bottom of the weighing hopper 43 is rotatably connected to the weighing end plate 421 via the connecting part 46, and a push-pull member is provided on the other side of the bottom side wall of the weighing hopper 43. After the push-pull member extends, it pushes the weighing hopper 43 to tilt and flip towards one side of the mixing assembly 1. Both sides of the weighing hopper 43 are equipped with vibrating parts 45. During the flipping process of the weighing hopper 43, the vibrating parts 45 simultaneously strike the weighing hopper 43.

[0051] When the powder mass in the weighing hopper 43 reaches the preset target value, the control system sends a drive command to the push-pull component. The push-pull component extends in a set direction, and its output end cooperates with the rotating connection part 46 of the weighing hopper 43, thereby driving the weighing hopper 43 to rotate around a preset axis. As the hopper rotates, the weighed powder is discharged along the inner wall of the hopper under the action of gravity and falls into the mixing cylinder 11, realizing automatic feeding after weighing.

[0052] Through the above structural design, the weighing hopper 43 functions as both a "weighing container" and a "feeding execution unit," enabling continuous mechanized operations of feeding, weighing, and dispensing without the need for manual transfer or additional unloading mechanisms. This structure reduces intermediate transfer links, lowers the risk of secondary powder contamination, and shortens the single batching cycle, facilitating high-throughput automated batching under multi-station parallel or batch cyclic conditions.

[0053] Furthermore, during the tipping and feeding process of the weighing hopper 43, a vibrating section 45 is installed to apply transient vibration or impact to the symmetrical weighing hopper 43, causing short-term micro-vibration of the inner wall of the hopper. This disrupts the adhesion layer or accumulation structure of the powder on the inner wall, promotes the shedding of residual powder, and avoids wall adhesion. This vibration process can be synchronized with the tipping action or triggered before or after the tipping ends, so that the hopper basically returns to an empty state after each feeding cycle, improving the consistency and repeatability of weighing between batches.

[0054] By combining the push-pull component for unloading and the vibration cleaning, an integrated structure for weighing and feeding is achieved. This also reduces the impact of residual mass on the weighing accuracy of the next batch, improving the long-term stability of the system. It is particularly suitable for automated batching scenarios with small dosage, high precision, and high frequency.

[0055] The push-pull component includes a drive rod 47 and a mounting rod 471. One end of the mounting rod 471 is fixed to the weighing end plate 421, and the other end is rotatably connected to one end plate of the telescopic drive rod 47. The other end of the drive rod 47 is rotatably connected to the guide plate 44 or the weighing hopper 43.

[0056] The drive rod 47 is preferably one of an electric actuator and a hydraulic actuator.

[0057] The drive rod 47 extends to push the weighing hopper 43 to flip, thereby completing the feeding.

[0058] The connecting part 46 includes a connecting shaft 461, a rotatable connecting sleeve 462 is sleeved on the surface of the connecting shaft 461, the connecting sleeve 462 is fixed on the bottom side wall of the weighing hopper 43, and connecting frames 463 are fixed at both ends of the connecting shaft 461, and the connecting frames 463 are fixed on the weighing end plate 421.

[0059] When the weighing hopper 43 flips, the connecting sleeve 462 rotates on the surface of the connecting shaft 461.

[0060] like Figures 8-11 As shown, the vibration unit 45 includes a trigger and a vibrating element 454. The trigger is installed on the outer shell or the support platform 41 of the weighing unit 42, and the vibrating element 454 is installed on the bottom side wall of the weighing hopper 43. The vibrating element 454 rotates with the weighing hopper 43, and the vibrating element 454, while rotating, strikes the bottom of the weighing hopper 43 after passing the trigger.

[0061] The triggering element includes a fixing frame 451, which is installed on the outer shell of the weighing unit 42 or the support platform 41. A mounting arc plate 452 is fixed on the top of the fixing frame 451. The mounting arc plate 452 is concentrically set with the center of the rotating hopper. Multiple triggering horizontal shafts 453 arranged in a ring array are fixed on the mounting arc plate 452. When the vibrating element 454 rotates with the weighing hopper 43, it passes through each triggering horizontal axis 453 in sequence.

[0062] The vibrating element 454 includes a bearing shaft 4541. One end of the bearing shaft 4541 is fixed to the bottom side wall of the weighing hopper 43 via an "L"-shaped connecting rod 4542. A self-rotating sleeve 4543 is sleeved on the surface of the bearing shaft 4541. A transmission plate 4544 that can overlap with the triggering horizontal shaft 453 is fixed on the surface of the self-rotating sleeve 4543. A transverse rod 4546 that can rotate on its end is installed on one side of the transmission plate 4544. A striking rod 4545 that overlaps with the bottom of the weighing hopper 43 is fixed on the end of the transverse rod 4546. A first coil spring and a second coil spring are respectively provided at the rotatable connection between the self-rotating sleeve 4543 and the bearing shaft 4541, and at the rotatable connection between the transverse rod 4546 and the striking rod 4545.

[0063] The first coil spring is sleeved on the surface of the bearing shaft 4541, and the two ends of the first coil spring are respectively fixed on the bearing shaft 4541 and the self-rotating sleeve 4543. The second coil spring is sleeved on the transverse rod 4546, and the two ends of the second coil spring are fixed to the transverse rod 4546 and the striking rod 4545 respectively.

[0064] When the first and second coil springs are not deformed, the end of the striking rod 4545 is attached to the bottom side wall of the weighing hopper 43, and the transmission plate 4544 is located on the side of the corresponding triggering horizontal shaft 453.

[0065] When the weighing hopper 43 is flipped, the transmission plate 4544 moves accordingly. When the transmission plate 4544 moves to the trigger horizontal shaft 453, it is blocked by the corresponding trigger horizontal shaft 453. Then, it rotates synchronously on the bearing shaft 4541 through the self-rotating sleeve 4543. The striking rod 4545 disengages from the bottom side wall of the weighing hopper 43 as the transmission plate 4544 rotates. At this time, the first coil spring deforms. Until the transmission plate 4544 disengages from the trigger horizontal rod during rotation, the striking rod 4545 instantly returns to its original position under the action of the first coil spring, thereby striking the weighing hopper 43, vibrating the weighing hopper 43 and the guide plate 44 fixedly connected to the weighing hopper 43, and preventing powder from sticking to the wall of the weighing hopper 43 and the guide plate 44.

[0066] During the rotation of the weighing hopper 43 back to its original position, the transmission plate 4544 is pushed in reverse by the corresponding trigger bar. At this time, the striking rod 4545 is pressed against the bottom side wall of the weighing hopper 43, causing the striking rod 4545 to rotate on its own axis at the end of the transverse bar 4546, so that the transmission plate 4544 can disengage from the trigger bar after reversing. During the above process, both the first coil spring and the second coil spring are deformed.

[0067] The support includes a lower bearing plate 22, at least two support plates 23 are fixed on the top side wall of the lower bearing plate 22, the top of the support plates 23 are fixed to the upper bearing plate 21, and the storage cylinder 31 and the bearing platform 41 are both fixed on the upper bearing plate 21.

[0068] This invention is not limited to the embodiments described above. Any changes in shape or structure fall within the protection scope of this invention. The protection scope of this invention is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this invention, but all such changes and modifications fall within the protection scope of this invention.
