Description

Technical Field

[0001] This utility model relates to the field of chemical experimental equipment technology, specifically to a laboratory feeding device. Background Technology

[0002] In chemical laboratories, automated material feeding systems have emerged to improve experimental efficiency and safety, reduce the workload of operators, and minimize personal danger to researchers. These systems can quickly and accurately mix and distribute materials, avoiding errors that may occur with manual operation. They also significantly shorten experimental preparation time and improve the parallelism and repeatability of experiments.

[0003] In chemical synthesis experiments, automated batching systems can precisely control the proportions and order of reactant addition, ensuring the smooth progress of the reaction. This is especially important for the synthesis of fine chemicals that require highly precise control.

[0004] In the prior art, Chinese utility model patent CN208320712U discloses an automatic quantitative feeding device for a chemical laboratory. This device includes a screw drive mechanism driven by a drive motor, a feeding box connected to the screw drive mechanism, multiple mixing boxes located below the feeding box, and a controller. An electromagnetic valve and an infrared receiver are installed at the outlet of each feeding box. Each mixing box contains a liquid level sensor and an infrared transmitter that works in conjunction with the infrared receiver. The drive motor, each infrared transmitter, the infrared receiver, each liquid level sensor, and the electromagnetic valve are electrically connected to the controller via conductive wires. This utility model's automatic quantitative feeding device has a high degree of automation and is easy to operate. By controlling the automatic movement of the feeding box and the automatic feeding operation through the controller, it solves the technical defects of slow, inaccurate, and labor-intensive manual mixing.

[0005] Although the above-mentioned feeding device can achieve automatic quantitative feeding and solve the defects of manual operation, when adding solid materials, the solid materials are prone to sticking to the inner wall of the feeding box, resulting in uneven feeding and, in severe cases, blockage of the discharge pipe, affecting experimental efficiency and quality. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a laboratory feeding device that uses a vibration mechanism to achieve vibration feeding, so that the material stuck to the wall in the solid material box can be detached, ensuring smooth material feeding and guaranteeing the efficiency and quality of the experiment.

[0007] To address the aforementioned technical problems, the present invention provides a laboratory feeding device, comprising a mounting frame, the mounting frame including a lower material tray support and an upper feeding support, a feeding bottle being disposed on the material tray support, a reaction vessel being connected below the feeding bottle, the feeding bottle including a solid material bottle, the lower end of the solid material bottle being provided with a discharge port, a solid feeding mechanism being disposed on the feeding support, the solid feeding mechanism including a vertical drive mechanism, the lower end of the vertical drive mechanism being provided with a vibration mechanism, the vertical drive mechanism driving the vibration mechanism to move downward to contact the solid material bottle, causing the residual material in the solid material bottle to vibrate and fall off.

[0008] Furthermore, the solid material bottle includes an outer sleeve and an inner bottle liner fitted inside the outer sleeve. The inner bottle liner and the outer sleeve slide vertically together. The discharge port is located on the lower side of the circumference of the inner bottle liner. The vertical driving mechanism is used to drive the inner bottle liner downward so that the discharge port is exposed outside the outer sleeve. A reset mechanism is also provided between the outer sleeve and the inner bottle liner. The reset mechanism is used to drive the inner bottle liner upward.

[0009] Furthermore, the vertical drive mechanism includes an electric push rod, the lower end of which is provided with a mounting cavity; the vibration mechanism includes a vibration striker, which is installed in the mounting cavity; the upper end of the inner bottle is provided with a solid bottle cap; and the lower end of the electric push rod is used to abut against the solid bottle cap.

[0010] Furthermore, the vertical drive mechanism also includes a position sensor, which is used to provide feedback on the displacement of the electric push rod, so that the discharge port protrudes from the outer sleeve.

[0011] Furthermore, the diameter of the solid bottle cap is larger than the inner diameter of the outer sleeve.

[0012] Furthermore, the lower end of the outer sleeve is provided with an inwardly extending portion, and the circumference of the inner bottle liner is provided with a stop portion corresponding to the position of the extension portion. The reset mechanism includes a reset spring disposed between the extension portion and the stop portion.

[0013] Furthermore, the bottom of the inner bottle liner is provided with an inclined surface extending toward the discharge port.

[0014] Furthermore, the feeding bottle also includes a liquid bottle, and the lower end of the liquid bottle is provided with a discharge valve.

[0015] Furthermore, the feeding bracket is equipped with a liquid feeding mechanism, which includes a liquid discharging needle and a gas supply device. The upper end of the liquid discharging needle is used to seal and communicate with the inside of the liquid bottle. The gas supply device is used to supply inert gas into the liquid bottle. The discharge valve is a self-operated pressure regulating valve.

[0016] Furthermore, the liquid feeding mechanism also includes a peristaltic pump and a flow meter.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] (1) By setting a solid feeding mechanism on the feeding bracket, which includes a vertical drive mechanism and a vibration mechanism, when the vertical drive mechanism drives the vibration mechanism to move down and contact the solid bottle, the residual material in the solid bottle can be vibrated and dislodged, greatly reducing the problem of material sticking to the wall and preventing solid material from sticking and accumulating inside the solid bottle and blocking the outlet, thus avoiding affecting experimental efficiency and quality. At the same time, a reaction vessel is set at the lower end of the feeding bottle, and the material can be directly connected to the reaction vessel, eliminating the need for intermediate connecting pipes and avoiding the risk of leakage and solid material clogging the pipe.

[0019] (2) The solid material bottle adopts an external sleeve and an internal bottle liner design. Under the push of the vertical drive mechanism, the internal bottle liner moves down and exposes the lower discharge port. At the same time, after the feeding is completed, during the process of the vertical drive mechanism moving up, the reset mechanism drives the internal bottle liner to move up in sync, so that the opening and closing of the discharge port can be controlled. At the same time, the size of the discharge port can be precisely adjusted to precisely control the material flow.

[0020] (3) The vertical drive mechanism adopts an electric push rod. The lower end of the electric push rod is provided with an installation cavity for installing the vibration striker. The lower end of the electric push rod abuts against the solid bottle cap and drives the inner bottle to move. On the one hand, it can accurately control the vertical movement and ensure that the vibration mechanism accurately acts on the solid bottle to dislodge residual materials. On the other hand, the structure is simple and compact, easy to implement and maintain.

[0021] (4) By using the position sensor to feedback the displacement of the electric push rod, the position of the discharge port exposed outside the sleeve can be accurately controlled, ensuring that the opening degree of the discharge port is appropriate and improving automation and accuracy.

[0022] (5) The diameter of the solid bottle cap is larger than the inner diameter of the outer sleeve, which can prevent the inner bottle from moving down too much and play a limiting role. At the same time, it can better transmit the vibration to the entire solid bottle during vibration, enhance the vibration effect, and make the residual material easier to fall off.

[0023] (6) The bottom of the inner bottle is set with an inclined surface extending towards the discharge port, which helps solid materials move more smoothly towards the discharge port under the action of gravity, reduces material residue, further solves the problems of material sticking and poor discharge, and improves material utilization and experimental results.

[0024] (7) The feeding bottle also includes a liquid feeding bottle to meet the needs of adding liquid materials during the experiment and to adapt to different experimental reaction feeding requirements.

[0025] (8) Inert gas is supplied into the liquid bottle using a gas supply device. Under pressure, the self-regulating pressure regulating valve at the bottom can open automatically, and the liquid material flows out. After the gas supply is stopped, the self-regulating pressure regulating valve can close automatically, realizing automatic feeding of liquid material and ensuring stable and accurate discharge. At the same time, the continuous supply of inert gas can blow away the residual material in the liquid bottle to avoid residue.

[0026] (9) By using a peristaltic pump and a flow meter, the liquid material can be dripped, and the amount of material added can be precisely controlled. This not only ensures the accuracy of the material addition, but also increases the flexibility and reliability. Attached Figure Description

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings: Specific Implementation Example 1:

[0044] like Figure 9 As shown, in this embodiment, in the horizontal direction, the length direction of the feeding bracket 6 is the front-to-back direction, as... Figure 10 As shown, the width direction of the feeding bracket 6 is the left-right direction.

[0045] refer to Figures 1 to 8 This utility model discloses a laboratory feeding device, including a mounting frame 5. The mounting frame 5 includes a lower material tray support 4 and an upper feeding support 6. A feeding bottle 7 is provided on the material tray support 4. A reaction vessel (not shown in the figure) is connected to the lower part of the feeding bottle 7. The feeding bottle 7 includes a solid material bottle 31. The lower end of the solid material bottle 31 is provided with a discharge port 313. A solid feeding mechanism is provided on the feeding support 6. The solid feeding mechanism includes a vertical drive mechanism. The lower end of the vertical drive mechanism is provided with a vibration mechanism. The vertical drive mechanism drives the vibration mechanism to move down to contact the solid material bottle 31, causing the residual material in the solid material bottle 31 to vibrate and fall off.

[0046] Specifically, in this embodiment, such as Figure 1 , 2 As shown, a feeding drive head 1 is provided on the feeding bracket 6. The feeder drive head includes an external housing assembly 11, and the solid feeding mechanism is integrated inside the housing assembly 11. Figure 3 , 4 As shown, a feeding tray 3 is detachably installed on the feeding bracket 6. The feeding tray 3 includes a bottom tray 33 and multiple bottle support columns 34 arranged in a circumferential array on the tray 33. The feeding bottle 7 is locked between the bottle support columns 34 to prevent displacement and shaking. The lower end of the feeding tray 3 is provided with an opening for the lower end of the feeding bottle 7 to be fed.

[0047] When feeding is required, first add the corresponding material into the feeding bottle 7, then install the feeding bottle 7 on the tray 33, and then move the feeding tray 3 as a whole into the feeding bracket 6. The feeding bracket 6 is provided with an installation position (not shown in the figure). The feeding tray 3 is placed in the installation position, and the feeding bottle 7 is aligned with the corresponding drive mechanism of the feeding drive head 1 to complete the feeding.

[0048] Specifically, in this embodiment, the mounting position can be a mounting groove that fits the bottom of the feeding tray 3, or in other embodiments, the mounting position can be a positioning block on both sides of the feeding tray 3 to achieve a fixed position.

[0049] Specifically, in this embodiment, a feeding tray lifting mechanism 2 is also provided on the mounting frame 5. The feeding tray lifting mechanism 2 is used to drive the feeding tray 3 to lift as a whole, so as to drive the feeding bottle 7 to connect with the feeding drive head 1 to complete the feeding preparation, and then use the feeding drive head 1 to complete the feeding.

[0050] Specifically, in this embodiment, such as Figure 9 , 10 As shown, two sets of feeding tray lifting mechanisms 2 are symmetrically arranged in the left and right directions. The upper ends of the two sets of feeding lifting mechanisms are set on the feeding bracket 6 and the lower ends are connected to the material tray bracket 4.

[0051] Specifically, each feeding tray lifting mechanism 2 includes two drive wheels 21 that are rotatably arranged in a front-to-back direction. The drive wheels 21 are rotatably mounted on the feeding bracket 6 via mounting bases 210. The two drive wheels 21 are connected by an "∞"-shaped steel wire rope 29. A steel wire guide wheel 26 is rotatably mounted on the feeding bracket 6 at the lower middle position of the steel wire rope 29. The steel wire rope 29 is attached to the steel wire guide wheel 26, which provides support and guidance.

[0052] Specifically, the drive wheel 21 is provided with annular grooves at intervals along its circumference. The wire rope 29 is wound in the annular grooves of the two drive wheels 21 and twisted in the middle. The friction between the annular groove and the wire rope 29 can drive the wire rope 29 to slide in the annular groove when the drive wheel 21 rotates, so as to realize the linkage of the two drive wheels 21 by using the wire rope 29.

[0053] When one of the drive wheels 21 rotates, the other drive wheel 21 rotates in the opposite direction. For example... Figure 9 As shown, when the rear drive wheel 21 rotates clockwise, it drives the front drive wheel 21 to rotate counterclockwise via the "∞"-shaped steel wire rope 29.

[0054] In the left-right direction, the drive wheels 21 of the two sets of feeding tray lifting mechanisms 2 are connected by a linkage shaft 25, and the drive wheels 21 and the corresponding linkage shafts 25 are anti-rotationally engaged. Two connecting frames 28 are provided on the feeding bracket 6 at intervals in the left-right direction. The front and rear ends of the connecting frame 28 extend to the front and rear drive wheels 21 respectively, and the linkage shafts 25 on the front and rear sides are rotatably supported on the connecting frame 28.

[0055] In each feeding tray lifting mechanism 2, crankshafts 22 are respectively mounted on the side of the front and rear linkage shafts 25 near the drive wheel 21 to prevent rotation. When the drive wheel 21 rotates, it drives the crankshafts 22 to rotate. The lower ends of the two crankshafts 22 are respectively hinged to the front crank 23 and the rear crank 24, which are symmetrically arranged in the front-rear direction. The lower ends of the front crank 23 and the rear crank 24 are respectively hinged to the front and rear sides of the feeding tray bracket 4. The two crankshafts 22, the front crank 23, the rear crank 24, and the feeding tray bracket 4 constitute a five-bar linkage mechanism.

[0056] A drive motor 27 is provided on the right rear side of the feeding bracket 6. The drive motor 27 drives the linkage shaft 25 on the rear side to rotate, thereby realizing the rotation of the two drive wheels 21 on the rear side, and thus realizing the synchronous operation of the two sets of feeding plate lifting mechanisms 2.

[0057] In this embodiment, the feeding tray 6 is fixed to the laboratory floor via a support frame or other structure. Two sets of symmetrical five-bar linkages are used to raise and lower the tray 4, which in turn raises and lowers the feeding tray 3 on the tray 4.

[0058] Specifically, when it is necessary to raise the feeding tray 3, the drive motor 27 drives the two rear drive wheels 21 to rotate counterclockwise. Under the drive of the wire rope 29, the two front drive wheels 21 rotate clockwise. At this time, the crankshafts 22 on the front and rear sides rotate in opposite directions, and the lower ends of the front crank 23 and the rear crank 24 deflect inward and move upward relative to each other, thereby driving the tray support 4 to rise, and driving the feeding tray 3 to rise. When it is necessary to lower the feeding tray 3, the operation is reversed.

[0059] Of course, in other embodiments, when meeting actual usage requirements, the wire rope 29 may not be provided. In this case, the two linkage shafts 25 are driven to rotate by a drive motor 27. The lifting and lowering action of the feeding plate 3 can also be achieved by directly driving the front and rear drive wheels 21 to rotate synchronously in opposite directions or in the same direction using the two drive motors 27.

[0060] Of course, in other embodiments, the feeding tray lifting mechanism 2 can also be a lifting cylinder. Specifically, the feeding tray bracket 4 is also fixed to the ground. A mounting plate is provided on the feeding tray bracket 4 at the position corresponding to the feeding drive head 1. The mounting position is set on the mounting plate. Two sets of lifting cylinders are symmetrically arranged in the left and right directions between the mounting plate and the feeding tray 6. The position of the lifting cylinders avoids the feeding tray 3 and will not interfere with the entry and exit of the feeding tray 3. The lifting cylinders drive the mounting plate to rise and fall, thereby driving the feeding tray 3 to rise and fall as a whole to complete the docking.

[0061] Preferably, in this embodiment, the solid material bottle 31 includes an outer sleeve 311 and an inner bottle liner 312 fitted inside the outer sleeve 311. The inner bottle liner 312 and the outer sleeve 311 are vertically slidably fitted together. The discharge port 313 is located on the lower side of the circumference of the inner bottle liner 312. A reset mechanism is also provided between the outer sleeve 311 and the inner bottle liner 312. The vertical drive mechanism is used to drive the inner bottle liner 312 to move downward against the force of the reset mechanism, so that the discharge port 313 is exposed outside the outer sleeve 311, completing the discharge of solid material. After the discharge is completed, the vertical drive mechanism moves upward, and the reset mechanism drives the inner bottle liner 312 to move upward synchronously, completing the reset of the inner bottle liner 312.

[0062] With this configuration, the solid material bottle 31 adopts an outer sleeve 311 and an inner bottle liner 312. Under the push of the vertical drive mechanism, the inner bottle liner 312 moves down, exposing the lower discharge port 313. At the same time, after the feeding is completed, during the upward movement of the vertical drive mechanism, the reset mechanism synchronously drives the inner bottle liner 312 to move up, making the opening and closing of the discharge port 313 controllable. At the same time, the size of the discharge port 313 can be precisely adjusted to accurately control the material flow.

[0063] Specifically, in this embodiment, such as Figure 2As shown, the vertical drive mechanism includes an electric push rod 12 vertically disposed inside the sleeve assembly. The lower end of the electric push rod 12 has a mounting cavity 121. The vibration mechanism includes a vibrating striker 14, which is installed inside the mounting cavity 121. A solid bottle cap 317 is disposed at the upper end of the inner bottle liner 312. The position of the electric push rod 12 corresponds to the position of the solid bottle cap 317. The electric push rod 12 moves downwards, and its lower end abuts against the solid bottle cap 317, thereby driving the inner bottle liner 312 to move up and down. The vertical drive mechanism uses an electric push rod 12, with a mounting cavity 121 at its lower end for mounting the vibrating striker 14. The lower end of the electric push rod 12 abuts against the solid bottle cap 317, driving the inner bottle liner 312 to move. This allows for precise control of vertical movement, ensuring the vibration mechanism accurately acts on the solid bottle 31 to dislodge residual material. Furthermore, the structure is simple and compact, easy to implement and maintain.

[0064] Preferably, in this embodiment, such as Figure 5 As shown, the length of the inner bottle liner 312 is greater than the length of the outer sleeve 311. In the initial state, under the action of the reset mechanism, the upper end of the inner bottle liner 312 extends out of the outer sleeve 311, and the lower end of the inner bottle liner 312 is not higher than the lower end of the outer sleeve 311, thus blocking the discharge port 313. At the same time, the diameter of the solid bottle cap 317 is greater than the inner diameter of the outer sleeve 311. This arrangement serves two purposes: firstly, the solid bottle cap 317 prevents the inner bottle liner 312 from moving excessively downwards, acting as a limiting element; secondly, during vibration, it better transmits vibration to the entire solid material bottle 31, enhancing the vibration effect and making it easier for residual material to fall off. It also prevents the electric push rod 12 from directly contacting the solid sleeve and causing damage.

[0065] Of course, in other embodiments, when meeting actual usage requirements, the outer diameter of the solid bottle cap 317 can be equal to the inner diameter of the outer sleeve 311. By setting the displacement limit position of the electric push rod 12, the inner bottle liner 312 can also be prevented from moving too far downward. At the same time, by setting the position of the electric push rod 12 so that its lower end corresponds to the center of the solid bottle cap 317, the electric push rod 12 can also be prevented from directly contacting the outer sleeve 311.

[0066] Preferably, in this embodiment, the vertical drive mechanism further includes a position sensor 13. The position sensor 13 is used to provide feedback on the displacement of the electric push rod 12, so that the discharge port 313 protrudes from the outer sleeve 311. By using the position sensor 13 to control the displacement of the electric push rod 12, the position of the discharge port 313 protruding from the outer sleeve 311 is accurately controlled, ensuring that the opening degree of the discharge port 313 is appropriate, improving automation and accuracy, while avoiding excessive extension of the electric push rod 12 and damage to the solid material bottle 31.

[0067] Preferably, in this embodiment, such as Figure 5As shown, an inwardly extending extension 314 is provided at the lower end of the outer sleeve 311, and a stop 315 is provided on the circumference of the inner bottle liner 312 corresponding to the position of the extension 314. The reset mechanism includes a reset spring 316 disposed between the extension 314 and the stop 315.

[0068] Specifically, such as Figure 5 As shown, the inner bottle liner 312 includes an upper large-diameter section, a lower small-diameter section, and a middle variable-diameter section. The inner diameter of the upper large-diameter section is adapted to the inner diameter of the outer sleeve 311. The radially inner side of the extension 314 extends to the circumference of the small-diameter section, and the small-diameter section slides in space with the extension and the inner wall of the outer sleeve 311. The middle variable-diameter section is a variable-diameter structure that decreases in size from top to bottom, and its vertical cross-section is trapezoidal. The stop 315 is provided on the hypotenuse of the trapezoid, and the lower end of the stop 315 is flat. The two ends of the return spring 316 are respectively connected to the lower end of the stop 315 and the upper end of the extension 314.

[0069] Preferably, in this embodiment, the bottom of the inner bottle 312 is provided with an inclined surface 318 extending toward the discharge port 313, and the inclined surface 318 is an arc-shaped surface with an inwardly concave arc cross-section. In other embodiments, the inclined surface 318 may also be an inclined surface with a straight cross-section. The inclined surface 318 helps solid materials move more smoothly toward the discharge port 313 under the action of gravity, reducing material residue, further solving the problems of material sticking and poor discharge, and improving material utilization and experimental results.

[0070] Preferably, in this embodiment, the feeding bottle 7 further includes a liquid bottle 32, and the lower end of the liquid bottle 32 is provided with a discharge valve 322.

[0071] Specifically, in this embodiment, such as Figure 7 , 8 As shown, the feeding bracket 6 is equipped with a liquid feeding mechanism, which includes a liquid discharging needle 16 and a gas supply device (not shown in the figure). The upper end of the liquid discharging needle 16 is used to seal and communicate with the inside of the liquid bottle 32, and the gas supply device is used to supply inert gas into the liquid bottle 32. The discharge valve 322 is a one-way valve, specifically a self-operated pressure regulating valve.

[0072] In this way, inert gas is supplied into the liquid bottle 32 by the gas supply equipment. Under pressure, the self-regulating pressure regulating valve at the bottom can be opened automatically, and the liquid material flows out. After the gas supply is stopped, the self-regulating pressure regulating valve can be closed automatically, realizing automatic feeding of liquid material and ensuring stable and accurate discharge. At the same time, the continuous supply of inert gas can blow away the residual material in the liquid bottle 32 to avoid residue.

[0073] Specifically, in this embodiment, the liquid dispensing needle 16 is arranged vertically inside the housing assembly 11 and spaced horizontally from the solid feeding mechanism. In the initial position, the lower end of the liquid dispensing needle 16 is lower than the lower end of the electric push rod 12 to prevent interference between the electric push rod 12 and the other feeding bottles 7 when the liquid dispensing needle 16 is connected to the liquid bottle 32.

[0074] The air supply device is installed outside the housing assembly 11, and the liquid feeding needle 16 is connected to the air supply device through the liquid air inlet pipe 15. Specifically, a mounting hole is provided on the circumferential surface of the housing assembly 11. The air inlet end of the liquid air inlet pipe 15 is installed in the mounting hole, and the air outlet end is connected to the liquid feeding needle 16. The air outlet end of the air supply device is connected to the liquid air inlet channel through the mounting hole.

[0075] In this embodiment, a liquid bottle cap 323 is provided on the top of the liquid bottle 32, and an air inlet valve 321 is installed on the liquid bottle cap 323. The lower end of the liquid dispensing needle 16 is used to connect to the air inlet valve 321, through which inert gas is introduced into the liquid bottle 32. Specifically, in this embodiment, the air inlet valve 321 is also a one-way valve, specifically a self-regulating pressure regulating valve. Under the gas supply of the gas supply equipment, the gas is injected into the air inlet valve 321 through the liquid dispensing needle 16. Under pressure, the air inlet valve 321 opens, injecting gas into the liquid bottle 32. Of course, in other embodiments, the air inlet valve 321 and the discharge valve 322 can also be solenoid valves, which are opened and closed by electrical control.

[0076] Preferably, in this embodiment, the liquid feeding mechanism further includes a peristaltic pump and a flow meter. Specifically, the peristaltic pump and the flow meter are installed at the discharge end of the liquid bottle 32. The peristaltic pump and the flow meter are used to accurately control the feeding amount, which not only ensures the accuracy of feeding, but also increases flexibility and reliability, and can realize the function of dripping liquid materials.

[0077] Specifically, in this embodiment, such as Figure 3 , 4 As shown, a solid material bottle 31 is placed in the center of the material tray, and six feeding bottles 7 are arranged in a circumferential array around the outer periphery of the solid material bottle 31. The six circumferential feeding bottles 7 include three solid material bottles 31 and three liquid material bottles 32, which are arranged sequentially. Specifically, a solid feeding mechanism and a liquid feeding mechanism are respectively arranged on the feeding drive head 1 corresponding to the positions of each solid material bottle 31 and liquid material bottle 32.

[0078] Of course, in other embodiments, when meeting actual needs, only one set of solid feeding mechanism and liquid feeding mechanism can be set. In this case, the feeding bottles 7 are arranged sequentially in a ring, and the solid bottles 31 and liquid bottles 32 can be arranged according to the feeding sequence. At this time, a rotating disk is set on the inner top surface of the housing assembly 11, and the outer periphery of the rotating disk corresponds to the top surface of each feeding bottle 7. The liquid feeding mechanism and the solid feeding mechanism are installed on the outer periphery of the rotating disk. The rotating disk is driven to rotate by a rotating motor and lifted and lowered by a lifting cylinder. As the solid feeding mechanism and the liquid feeding mechanism rotate with the rotating disk, they pass through each feeding bottle 7 in sequence to complete the feeding. In other embodiments, the number and position of the solid bottles 31 and liquid bottles 32 can be set according to actual needs.

[0079] The working process of this application:

[0080] First, in the preparation room, the liquid and solid materials required for the reaction are added into the liquid bottle 32 and the solid bottle 31 respectively. The solid bottle 31 and the liquid bottle 32 are then installed and fixed on the feeding tray 3. The feeding tray 3 is placed in the installation position of the tray bracket 4 by the robot arm. The feeding tray 3 is locked and then raised by the feeding tray lifting mechanism 2 to connect with the feeding drive head 1, thus completing the feeding preparation work.

[0081] When solid material needs to be added, the electric push rod 12 corresponding to the top of the solid material bottle 31 extends and presses down the solid bottle cap 317. The middle bottle liner overcomes the elastic force of the return spring 316 and moves vertically downward. After the position sensor 13 feedbacks that the electric push rod 12 has extended to the specified displacement, the discharge port 313 at the bottom of the middle bottle liner extends appropriately, and the solid material in the middle bottle liner flows out. The vibration striker 14 is activated, driving the middle bottle liner to vibrate, realizing vibration feeding, completing the fast and smooth feeding of solid material, avoiding material sticking to the wall, and improving feeding efficiency and accuracy. At the same time, the solid material is shaken off and removed, which also avoids residual material clogging the discharge port 313, and ensures that the solid material is added sufficiently, avoiding under-addition and material waste. This ensures the quality and efficiency of the experiment.

[0082] After the solid material is added, the electric push rod 12 retracts, and the inner bottle liner 312 moves upward under the action of the return spring 316 until it returns to the initial position, sealing the discharge port 313.

[0083] When liquid material needs to be added, the feeding tray lifting mechanism 2 moves the feeding tray 3 upward until the liquid discharge needle 16 connects to the air inlet valve 321, and the air supply equipment is supplied with air. Under pressure, the air inlet valve 321 opens, and inert gas enters the liquid bottle 32. Under continuous pressure, the discharge valve 322 at the bottom opens, and the liquid material flows out. After the liquid material has flowed out, inert gas is continuously introduced to blow away any remaining material in the liquid bottle 32 to prevent residue. At the same time, the peristaltic pump and flow meter enable the dripping function of the liquid material.

[0084] After feeding is completed, the feeding tray lifting mechanism 2 drives the feeding tray 3 to move down and fall back down. The robotic arm takes out the feeding tray 3, completing the entire feeding process.

[0085] The laboratory feeding device of this utility model has a solid feeding mechanism set on the feeding bracket 6. The solid feeding mechanism includes a vertical drive mechanism and a vibration mechanism. When the vertical drive mechanism drives the vibration mechanism to move down and contact the solid bottle 31, the residual material in the solid bottle 31 can be vibrated and dislodged, which greatly reduces the problem of material sticking to the wall and avoids solid material sticking and accumulating inside the solid bottle 31 and blocking the outlet 313, thus avoiding affecting the experimental efficiency and experimental quality.

[0086] The device integrates a peristaltic pump and flow meter for liquid dispensing, enabling drip-feeding of liquids. This is particularly important for experiments requiring precise control of the feed rate. The combined use of the peristaltic pump and flow meter not only ensures accurate dispensing but also increases the system's flexibility and reliability.

[0087] Solid sample bottle 31 and liquid sample bottle 32 have the same external dimensions, so they can be freely combined on the feeding tray 3. Users can choose to use all solid sample bottles 31 or all liquid sample bottles 32 according to different experimental needs. This design greatly improves the applicability and flexibility of the device and can meet the feeding volume requirements of various experimental reactions.

[0088] The bottom of the feeding bottle 7 connects directly to the reactor lid. This design eliminates the intermediate connecting pipes, which not only simplifies the system structure but also reduces the risk of leakage and solid material blockage, thus improving the safety and stability of the system.

[0089] In summary, this device, with its unique solid and liquid feeder design, efficient feeding method, and direct docking with the reactor, demonstrates its advanced technology and practicality in the field of experimental feeding. These features enable the device to provide high flexibility and adaptability while ensuring feeding accuracy and safety, meeting the needs of different experiments.

[0090] Example 2: This example provides a different solid material box. Unlike Example 1, in this example, when meeting actual usage requirements, the outlet of the solid material bottle is directly set at the bottom of the solid material bottle. At this time, a solenoid valve is set on the outlet to open and close the inlet and outlet, thereby realizing the discharge.

[0091] Example 3: This example provides a different vertical drive mechanism. Unlike Example 1, in this example, when meeting actual usage requirements, the vertical drive mechanism is a vertical drive cylinder. The telescopic rod of the drive cylinder extends downward, and a vibration mechanism is installed on the telescopic rod.

[0092] Example 4: This example provides a different vibration mechanism. Unlike Example 1, in this example, the vibration mechanism can be a vibration motor to meet actual usage requirements.

[0093] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.

[0094] In the description of the embodiments of this application, it should be noted that if terms such as "upper," "lower," "horizontal," or "inner" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of the invention is in use, they are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, terms such as "first" and "second" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0095] Furthermore, the use of the term "horizontal" does not imply that the component must be absolutely horizontal, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.
