Description

Technical Field

[0001] This utility model relates to the field of metering device technology, and more specifically, to a novel automatic liquid metering device. Background Technology

[0002] Titrators are used in research in disciplines such as chemistry, physics, and biology to accurately weigh various reagents and samples. For example, in drug development, they are used to accurately weigh various drug components to ensure the accuracy of drug formulations. In materials science research, they are used to accurately measure the mass of materials in order to study the relationship between material properties and mass.

[0003] Existing titration devices use a mechanical structure to adjust the orientation of a liquid storage mechanism, which then drips the required liquid into a corresponding measuring cup at the bottom. Weighing is then completed using a balance at the bottom of the measuring cup, ensuring measurement accuracy. This type of titration device is cumbersome to operate. Depending on the desired product, different raw materials need to be frequently switched, requiring the robotic arm to repeatedly move and grasp different liquid materials, severely impacting processing efficiency. Therefore, we propose a novel automatic liquid metering device. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a new type of automatic liquid metering device to solve the technical problem that the current titration device is inconvenient to use for the proportioning of various raw materials, which seriously affects the proportioning efficiency.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A novel automatic liquid metering device, comprising a metering mechanism, a rotating mechanism, and a driving mechanism. The metering mechanism is installed inside a housing and consists of two layers of shelves. The upper shelf of the two layers of shelves is equipped with a transmission component, and the lower shelf of the two layers of shelves is equipped with a precision balance. A pad is provided at the opening at the top of the housing, and frames are evenly distributed on the pad. The rotating mechanism is installed on the upper side inside the frames and consists of a turntable. The rotating shaft of the turntable is positioned on the frames by a clamp. Mother liquor bottles are arranged in a circular array outside the turntable. A dripping mechanism is installed at the bottom inside the frames, and a draining mechanism is installed on the pad.

[0006] In use, this invention is powered by an external power source. The operator starts the device via an external control device, activating the built-in servo motor drive mechanism to synchronously rotate the turntable. During rotation, the turntable switches the position of the outer mother liquor bottle. It stops when the mother liquor bottle aligns with the dripping mechanism. At this point, the lifting assembly is activated, causing the magnetic sleeve to rise. This adjusts the distance between the magnetic sleeve and the outer end cap of the mother liquor bottle. Once the distance is appropriate, the magnetic force of the sleeve attracts the solenoid valve, allowing the original liquid in the mother liquor bottle to drip through the solenoid valve's opening path along the iron core. The original liquid then passes through the magnetic sleeve and the liquid outlet, dripping into a measuring cup placed on the cup tray. The weight of the measuring cup rests on a precision balance, which detects the amount of original liquid dripped. When the preset amount is reached, the magnetic sleeve lowers, increasing the distance and weakening the magnetic force, closing the solenoid valve. The above structure enables quantitative weighing of the raw liquid, facilitating its extraction. The rotating disc structure allows the outer ring of mother liquor bottles to switch positions, enabling extraction of different raw liquids, reducing the time interval between raw liquid collection, and significantly improving efficiency. Even after the solenoid valve is closed, some un-dripped raw liquid remains on the valve's core. When the rotating mechanism is activated, centrifugal force throws the raw liquid on the core towards the collection hopper. From there, it is guided to the collection box through the lower outlet of the collection hopper and finally discharged through the drain pipe. The horizontal displacement of the collection hopper can be adjusted by activating the telescopic component to accommodate the spilled raw liquid. The adjustment port allows for easy adjustment of the lower opening of the collection hopper. This structural design prevents residual raw liquid from spilling into the equipment, thus avoiding internal contamination and ensuring the cleanliness of the equipment.

[0007] Preferably, the transmission assembly consists of a transmission disc and a transmission belt, and a cup is fixedly connected to the outside of the transmission belt via a bracket, the cup corresponding to the precision balance.

[0008] Preferably, the drive mechanism consists of a driven wheel and a driving wheel. The driven wheel is mounted on the rotating shaft of the turntable, and the driving wheel is rotatably mounted on the lower end of one side of the frame. The driven wheel and the driving wheel are connected by a belt drive.

[0009] Preferably, the dripping mechanism consists of a folding plate and a lifting assembly. The lifting assembly is installed at the bottom of the frame. The folding plate has a Z-shaped design, and a magnetic sleeve is installed through the lower surface of the folding plate.

[0010] Preferably, the pad is provided with liquid flow holes and adjustment ports at equal intervals, and the liquid flow holes correspond to the lower end holes of the cup, plate and magnetic sleeve.

[0011] Preferably, the draining mechanism consists of a liquid collecting hopper, a liquid collecting box, and a telescopic component, with the telescopic component connected to the rear end of the liquid collecting hopper. The lower end hole of the liquid collecting hopper passes through the adjustment port and is located inside the liquid collecting box, and a drain pipe is provided at the lower end of the liquid collecting box.

[0012] Preferably, the outer end of the mother liquor bottle is provided with an end cap, and an electromagnetic valve is installed inside the end cap. The electromagnetic valve corresponds to the position of the magnetic sleeve and the liquid collecting hopper.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model designs a rotating mechanism that activates a servo motor driven by a built-in servo motor, synchronously rotating a turntable. During the rotation, the position of the outer mother liquor bottle is switched. When the mother liquor bottle corresponds to the dripping mechanism, the mechanism stops. At this point, the lifting component is activated, causing the magnetic sleeve to rise. This allows the magnetic sleeve to adjust the distance between itself and the outer end cap of the mother liquor bottle. Once the distance is appropriate, the magnetic force of the magnetic sleeve attracts the electromagnetic valve, allowing it to open. The original liquid in the mother liquor bottle drips through the opening path of the electromagnetic valve along the iron core. The original liquid passes through the magnetic sleeve and the liquid outlet, dripping into a measuring cup placed on the cup tray. The weight of the measuring cup rests on a precision balance, which detects the amount of original liquid dripped. When the preset amount is reached, the magnetic sleeve descends, increasing the distance and weakening the magnetic force, closing the electromagnetic valve. This structure completes the quantitative weighing of the original liquid, facilitating its extraction. The turntable structure also allows the outer ring of mother liquor bottles to switch positions, facilitating the extraction of different original liquids, reducing the time interval between liquid collection, and significantly improving efficiency.

[0015] 2. This utility model also incorporates a drainage mechanism. Even after the solenoid valve is closed, some un-dripping liquid remains on the iron core of the solenoid valve. When the rotating mechanism is activated, centrifugal force causes the liquid on the iron core to be thrown towards the collection hopper. The liquid is then guided to the collection box through the lower outlet of the collection hopper and finally discharged through the drainage pipe. The horizontal displacement of the collection hopper can be achieved by activating the telescopic component, adjusting it to a position suitable for the spilled liquid. The adjustment port facilitates the adjustment of the lower opening of the collection hopper. Through the above structural design, the liquid residue is prevented from being thrown into the equipment, causing internal pollution and ensuring the cleanliness of the equipment.

[0026] like Figures 1 to 6As shown, this utility model relates to a novel automatic liquid metering device, comprising a metering mechanism 2, a rotating mechanism 5, and a driving mechanism 7. The metering mechanism 2 is installed inside a housing 1 and consists of two layers of shelves 202. The upper shelf of the two layers of shelves 202 is provided with a transmission assembly 201, and the lower shelf of the two layers of shelves 202 is provided with a precision balance 204. A pad 3 is provided at the upper opening of the housing 1, and frames 4 are evenly distributed on the pad 3. The transmission assembly 201 consists of a transmission disc and a transmission belt, and a cup / plate 203 is fixedly connected to the outside of the transmission belt via a bracket. The cup and plate 203 corresponds to the precision balance 204. The drive mechanism 7 consists of a driven wheel 701 and a driving wheel 703. The driven wheel 701 is mounted on the rotating shaft of the turntable 504, and the driving wheel 703 is rotatably mounted on the lower side of the frame 4. The driven wheel 701 and the driving wheel 703 are connected by a belt 702. The dripping mechanism 8 consists of a folding plate 801 and a lifting assembly 802. The lifting assembly 802 is mounted at the bottom of the frame 4. The folding plate 801 has a Z-shaped design, and a magnetic sleeve 803 is installed through the lower surface of the folding plate 801. The starting frame 4 has a built-in servo... The electric drive mechanism 7 drives the turntable 504 to rotate synchronously. During the rotation of the turntable 504, the position of the outer mother liquor bottle 501 is switched. When the mother liquor bottle 501 corresponds to the dripping mechanism 8, it stops. At this time, the lifting component 802 is activated to drive the magnetic sleeve 803 to rise, so that the magnetic sleeve 803 adjusts the distance between itself and the outer end cap 502 of the mother liquor bottle 501. When the distance is appropriate, the magnetic attraction of the magnetic sleeve 803 drives the solenoid valve 503 to open. The original liquid in the mother liquor bottle 501 drips down the iron core through the opening passage of the solenoid valve 503. The original liquid passes through the magnetic sleeve 803 and... The liquid drips from the outlet 301 into the measuring cup inserted into the cup tray 203. The entire weight of the measuring cup rests on the precision balance 204. The precision balance 204 detects the amount of liquid dripped. When the preset amount is reached, the magnetic suction sleeve 803 descends, the distance increases, the magnetic force weakens, and the solenoid valve 503 closes. The above structure completes the quantitative weighing of the liquid, facilitating the extraction of the liquid. The rotating disk 504 structure drives the outer ring-shaped mother liquor bottle 501 to switch positions, facilitating the extraction of different liquids, reducing the time interval between liquid collection and greatly improving efficiency.

[0027] like Figures 3 to 9As shown, this utility model relates to a novel automatic liquid metering device, comprising a metering mechanism 2, a rotating mechanism 5, and a driving mechanism 7. The rotating mechanism 5 is installed on the upper side inside the frame 4 and is composed of a turntable 504. The rotating shaft of the turntable 504 is positioned on the frame 4 by a clamp. Mother liquor bottles 501 are arranged in a circular array on the outer side of the turntable 504. A dripping mechanism 8 is installed at the bottom inside the frame 4. A draining mechanism 6 is installed on the pad 3. The pad 3 has equidistant openings. The system has a liquid outlet 301 and an adjustment port 302. The liquid outlet 301 corresponds to the lower end holes of the cup / plate 203 and the magnetic sleeve 803. The liquid drainage mechanism 6 consists of a liquid collecting hopper 601, a liquid collection box 602, and a telescopic component 603. The rear end of the liquid collecting hopper 601 is connected to the telescopic component 603. The lower end hole of the liquid collecting hopper 601 passes through the adjustment port 302 and is located inside the liquid collection box 602. The lower end of the liquid collection box 602 is provided with a drain pipe 604. The outer end of the mother liquor bottle 501 is provided with an end cap 502. Furthermore, an electromagnetic valve 503 is installed inside the end cover 502. The electromagnetic valve 503 consists of a sealing ring, a magnetically traction iron core, a spring, a sealing rubber, and an outer shell. It is assembled onto the main body of the end cover 502 with screws. The electromagnetic valve 503 corresponds to the positions of the magnetic sleeve 803 and the liquid collection hopper 601. When the electromagnetic valve 503 is closed, there is still some undribbled original liquid remaining on the iron core of the electromagnetic valve 503. When the rotating mechanism 5 is started, centrifugal force is generated, causing the original liquid on the iron core to be thrown towards the liquid collection hopper 601. Then, it is guided to the liquid collection box 602 through the lower outlet of the liquid collection hopper 601, and finally discharged through the drain pipe 604. The liquid collection hopper 601 can be horizontally moved by activating the telescopic component 603 to adjust it to a position suitable for the thrown original liquid. The position of the lower opening of the liquid collection hopper 601 can be easily adjusted through the adjustment port 302. Through the above structural design, the original liquid residue is prevented from being thrown into the equipment and causing internal pollution, thus ensuring the cleanliness of the equipment.

[0028] Working Principle: This embodiment provides a novel automatic liquid metering device. During use, the servo motor drive mechanism 7 built into the frame 4 drives the turntable 504 to rotate synchronously. During rotation, the turntable 504 switches the position of the outer mother liquor bottle 501. It stops when the mother liquor bottle 501 corresponds to the dripping mechanism 8. At this time, the lifting component 802 is activated, causing the magnetic sleeve 803 to rise, adjusting the distance between the magnetic sleeve 803 and the outer end cap 502 of the mother liquor bottle 501. When the distance is appropriate, the magnetic sleeve 803 magnetically attracts and opens the solenoid valve 503. The original liquid in the mother liquor bottle 501 drips through the opening passage of the solenoid valve 503 along the iron core. The original liquid passes through the magnetic sleeve 803 and the liquid outlet 301, dripping into the measuring cup inserted and placed on the cup tray 203. The overall weight of the measuring cup is within the precision range. On the precision balance 204, the amount of dripping raw liquid is detected. When the preset amount is reached, the magnetic suction sleeve 803 is lowered, the distance increases and the magnetic force weakens, and the solenoid valve 503 is closed. The above structure completes the quantitative weighing of raw liquid, which facilitates the extraction of raw liquid. When the solenoid valve 503 is closed, there is still raw liquid that has not dripped completely remaining on the iron core of the solenoid valve 503. When the rotating mechanism 5 is started, the centrifugal force causes the raw liquid on the iron core to be thrown towards the collection hopper 601. Then, it is guided through the lower outlet of the collection hopper 601 to the liquid collection box 602, and finally discharged through the drain pipe 604. The horizontal displacement of the collection hopper 601 can be driven by activating the telescopic component 603 to adjust it to a position suitable for the dropped raw liquid. The adjustment port 302 facilitates the adjustment of the position of the lower opening of the collection hopper 601.
