[0051] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for 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. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The terms "first position" and "second position" refer to two different positions.

[0053] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0054] like Figures 1 to 5As shown, this embodiment provides a freeze-dried pellet feeding device that can prevent damage to the freeze-dried pellets and ensure their quality. The freeze-dried pellet feeding device includes a fixed frame 1, a storage bin 2, and a first driving component 3.

[0055] Among them, see Figure 1 , Figure 2 , Figure 3 and Figure 8 The storage bin 2 is swayably mounted on the fixed frame 1. The storage bin 2 has a receiving cavity 221 for holding freeze-dried pellets. The receiving cavity 221 has a discharge port 223, which can communicate with the feed bin of the freeze-dried pellet dispensing device 10. The first driving member 3 is mounted on the fixed frame 1. The output end of the first driving member 3 can act on the storage bin 2 and drive the storage bin 2 to sway and tilt relative to the fixed frame 1 at a preset angle so that the freeze-dried pellets in the receiving cavity 221 can fall into the feed bin of the freeze-dried pellet dispensing device 10 through the discharge port 223.

[0056] The freeze-dried pellet feeding device provided in this embodiment, when it needs to feed the freeze-dried pellet dispensing device 10, controls the first driving component 3 to drive the storage bin 2 to swing and tilt relative to the fixed frame 1 at a preset angle (e.g., Figure 5 As shown, the receiving cavity 221 of the storage bin 2 is tilted relative to the horizontal plane. At this time, the freeze-dried balls in the receiving cavity 221 can roll towards the discharge port 223 under their own gravity, and then roll down into the feeding bin of the freeze-dried ball dispensing device 10 through the discharge port 223. That is, this freeze-dried ball feeding device only needs to control the storage bin 2 to tilt at a certain angle through the first driving component 3 to make the freeze-dried balls automatically enter the feeding bin of the freeze-dried ball dispensing device 10, realize automatic feeding of the freeze-dried ball dispensing device 10, and improve the feeding efficiency of freeze-dried balls. Moreover, the feeding method of automatically dropping freeze-dried balls by tilting the storage bin 2 can avoid the freeze-dried balls from being damaged by vibration, prevent the freeze-dried balls from being damaged, ensure the quality of the freeze-dried balls after dispensing, and improve the product qualification rate.

[0057] Optionally, see Figure 2 and Figure 3The storage bin 2 includes a first end and a second end arranged opposite to each other. The first end serves as a connecting end, and the second end serves as a free end. For example, the first end of the storage bin 2 is rotatably connected to the fixed frame 1. The first driving member 3 is used to drive the storage bin 2 to swing up and down relative to the fixed frame 1, so that the second end rises and falls relative to the first end. That is, the first driving member 3 applies a force to the storage bin 2, so that the storage bin 2 rises and falls relative to the fixed frame 1, thereby tilting the storage bin 2 relative to the fixed frame 1 at a preset angle. Specifically, when the output end of the first driving member 3 rises, it can apply an upward force to the storage bin 2. Since the first end of the storage bin 2 is rotatably connected to the fixed frame 1, the second end, which is the free end in the storage bin 2, can rise relative to the first end, causing the storage bin 2 to tilt relative to the fixed frame 1. This makes the terrain at the discharge port 223 relatively lower, and the freeze-dried balls in the receiving cavity 221 can roll down to the discharge port 223 under their own gravity, realizing the automatic falling of the freeze-dried balls into the feeding bin of the freeze-dried ball dispensing device 10. The lifting and adjusting of the tilt angle of the storage bin 2 is a simple and easy-to-implement driving structure. The lifting and adjusting drive is stable and can prevent the freeze-dried balls from breaking to the greatest extent, thus ensuring the quality of the freeze-dried balls after packaging.

[0058] For example, the first driving component 3 can be a cylinder, with the cylinder's output rod movably connected to the storage bin 2. By lifting the second end of the storage bin 2, the storage bin 2 is tilted at a certain angle. In other embodiments, the first driving component 3 can also be a linear driving component such as an electric cylinder, a linear motor, or a lead screw and nut mechanism.

[0059] The aforementioned preset angle can be determined based on the actual amount of freeze-dried pellets replenished. For example, if the amount of freeze-dried pellets replenished is large, the height of the first drive component 3 can be controlled to be higher, so that the storage bin 2 tilts at a larger angle; if the amount of freeze-dried pellets replenished is small, the height of the first drive component 3 can be controlled to be lower, so that the storage bin 2 tilts at a smaller angle.

[0060] In this embodiment, refer to Figure 5 In terms of orientation, the left end of storage bin 2 is the first end, and the right end of storage bin 2 is the second end.

[0061] Optionally, see Figure 2 , Figure 3 and Figure 4 The output end of the first driving component 3 is provided with a rotatable rolling element 31, which can roll in cooperation with the outer peripheral surface of the storage bin 2. During the process of the first driving component 3 driving the second end of the storage bin 2 to rise and fall, the rolling element 31 always rolls in cooperation with the outer peripheral surface of the storage bin 2 in the tilt direction of the storage bin 2, which can reduce the driving resistance of the first driving component 3 and improve the driving efficiency.

[0062] For example, the rolling element 31 is a roller, see [reference] Figure 3 and Figure 4The output end of the first driving component 3 is provided with a connecting block 32, and a connecting shaft is rotatably provided on the connecting block 32. Each end of the connecting shaft is provided with a roller, and the two rollers simultaneously roll with the storage bin 2, which can improve the stability of the cooperation between the first driving component 3 and the storage bin 2.

[0063] In other embodiments, the output end of the first driving member 3 can also be slidably connected to the storage bin 2. During the lifting and lowering process of the first driving member 3, the output end of the first driving member 3 adaptably slides relative to the storage bin 2, thereby preventing the storage bin 2 from interfering with the lifting and lowering of the first driving member 3. Specifically, a slider can be provided at the output end of the first driving member 3, and correspondingly, a groove extending along the inclined direction of the storage bin 2 is provided on the storage bin 2, with the slider slidingly engaging with the groove.

[0064] Optionally, see Figure 2 and Figure 3 The freeze-dried pellet feeding device also includes an elastic element 4. One end of the elastic element 4 is connected to the fixed frame 1, and the other end is connected to the storage bin 2. The rolling element 31 can always be in contact with the outer peripheral surface of the storage bin 2 under the elastic force of the elastic element 4. That is, the elastic element 4 is always in an energy storage state and can apply a pulling force to the storage bin 2, so that the outer peripheral surface of the storage bin 2 is always in contact with the rolling element 31. This ensures that the rolling element 31 can always roll and cooperate with the outer peripheral surface of the storage bin 2 during the lifting and lowering process of the first drive element 3, thereby improving the stability of the storage bin 2 during the tilting process. At the same time, the setting of the elastic element 4 can limit the maximum rising height of the second end of the storage bin 2, preventing the storage bin 2 from tilting excessively and causing it to overturn.

[0065] In addition, the elastic element 4 also has a resetting function for the storage bin 2, allowing the storage bin 2 to move downwards and reset to a horizontal position. Specifically, when the first driving element 3 descends, the storage bin 2 can descend accordingly under the pulling force of the elastic element 4, causing the storage bin 2 to automatically reset.

[0066] For example, the elastic element 4 is a tension spring. See also Figure 3 The fixed frame 1 is provided with a first connecting plate 113, and the storage bin 2 is provided with a second connecting plate 213. Both ends of the tension spring are provided with hooks. The first connecting plate 113 and the second connecting plate 213 are provided with hanging holes. The hooks are hooked into the corresponding hanging holes to ensure that the tension spring is reliably connected to the fixed frame 1 and the storage bin 2, and to facilitate disassembly.

[0067] Of course, in other embodiments, the elastic element 4 may not be provided. For example, the rolling element 31 at the output end of the first driving element 3 rolls and connects with the storage bin 2, or the output end of the first driving element 3 slides and connects with the storage bin 2. When the output end of the first driving element 3 rises and falls, it drives the storage bin 2 to move together, so that the storage bin 2 can tilt at a preset angle and also return to its original position.

[0068] Optionally, see Figure 3A guide cylinder 1221 is provided on the fixed frame 1, and a first guide rod 212 is provided at the second end of the storage bin 2. The first guide rod 212 is inserted into the guide cylinder 1221 and slides in cooperation with the guide cylinder 1221. During the process of the first driving component 3 driving the second end of the storage bin 2 to rise and fall, the first guide rod 212 always slides in cooperation with the guide cylinder 1221, which can prevent the storage bin 2 from tilting during the rising and falling process and further improve the stability of the storage bin 2 during the tilting process.

[0069] Optionally, see Figure 1 , Figure 2 and Figure 3 The fixed frame 1 includes a base 11 and a support frame 12 supported on the base 11. The first drive component 3 is disposed on the base 11, and the storage bin 2 is rotatably disposed on the support frame 12. The base 11 can be fixed on the base of the freeze-dried ball packaging production line to mount the freeze-dried ball feeding equipment above the freeze-dried ball dispensing equipment 10. The support frame 12 can mount the storage bin 2 above the first drive component 3, providing lifting space for the first drive component 3, facilitating the adjustment of the tilt angle of the storage bin 2 by the first drive component 3.

[0070] Specifically, see Figure 2 and Figure 3 The base 11 is a rectangular frame structure. The support frame 12 includes a column 121 and a support frame 122. A column 121 is set at each of the four corners of the support frame 122. All four columns 121 are fixedly connected to the base 11. The first driving member 3 is located in the space formed between the support frame 122 and the base 11.

[0071] See Figure 2 , Figure 4 and Figure 5 The support frame 12 of the fixing frame 1 is provided with a connecting seat 1222, and the connecting seat 1222 is provided with a connecting lug. (See reference) Figure 6 The storage bin 2 is provided with a rotating groove 217, and the connecting ear is rotatably installed in the rotating groove 217 through a rotating shaft 25 to realize the rotating connection between the storage bin 2 and the support frame 12.

[0072] Furthermore, such as Figure 3 As shown, the support frame 122 of the support bracket 12 has a recessed fixing groove, and the connecting seat 1222 is at least partially located in the fixing groove to position the connecting seat 1222. The connecting seat 1222 can be fixed to the support frame 122 by bolts, screws or other fasteners.

[0073] Optionally, see Figure 2 and Figure 4The fixed frame 1 is equipped with an adjustable mounting base 111. The housing of the first drive component 3 is fixed to the mounting base 111. The maximum tilt angle of the storage bin 2 can be adjusted by adjusting the tilt angle of the mounting base 111. When the tilt angle of the mounting base 111 relative to the fixed frame 1 changes, the lifting direction of the first drive component 3 changes accordingly, thereby changing the maximum vertical lifting height of the output end of the first drive component 3 and adjusting the maximum tilt angle of the storage bin 2. Before feeding freeze-dried pellets, the tilt angle of the mounting base 111 relative to the fixed frame 1 can be adjusted according to the feeding requirements of the freeze-dried pellets to ensure that the maximum tilt angle of the storage bin 2 meets the requirements.

[0074] See Figure 2 , Figure 3 and Figure 4 The base 11 of the fixing frame 1 is provided with a first fixing seat 112. The mounting seat 111 is rotatably mounted on the first fixing seat 112. The tilt angle can be adjusted by rotating the mounting seat 111. Specifically, a locking structure (such as a locking bolt or locking pin) can be provided on the first fixing seat 112. When it is necessary to adjust the tilt angle of the mounting, the locking structure is released from the mounting seat 111, and then the mounting seat 111 is rotated to adjust the tilt angle. After the mounting seat 111 is adjusted to the right tilt angle, the mounting seat 111 is locked and fixed on the first fixing seat 112 by the locking structure to prevent the mounting seat 111 from continuing to rotate and to ensure that the first driving component 3 is securely fixed.

[0075] Optionally, see Figure 2 , Figure 3 and Figure 4 The storage bin 2 has a feed inlet 222. The freeze-dried pellet feeding equipment also includes a sealing component 5 located at the feed inlet 222. The sealing component 5 is used to seal or open the feed inlet 222. When feeding freeze-dried pellets, the feed inlet 222 is opened by the sealing component 5. After a certain amount of freeze-dried pellets are loaded into the receiving cavity 221, the feed inlet 222 is sealed by the sealing component 5. This prevents external dust and debris from entering the receiving cavity 221 and ensures that the freeze-dried pellets are not contaminated.

[0076] Continue reading Figure 2 , Figure 3 and Figure 4 The storage bin 2 is equipped with a feed hopper 23 at the feed inlet 222. The feed hopper 23 has a guide ramp for guiding the freeze-dried balls to the feed inlet 222. The feed hopper 23 expands the feeding space, making it easier to add freeze-dried balls into the receiving cavity 221, improving the feeding efficiency of freeze-dried balls, and preventing the freeze-dried balls from falling out. By providing a guide ramp on the feed hopper 23, it is easier for the freeze-dried balls to roll from the feed inlet 222 into the receiving cavity 221, further improving the feeding efficiency of freeze-dried balls. For details, please refer to... Figure 4 The guide slope is set downward along the direction close to the feed inlet 222.

[0077] For example, the feed hopper 23 is shaped like a shovel. In other embodiments, the feed hopper 23 may also be shaped like a funnel.

[0078] Optionally, see Figure 3 and Figure 4 The sealing assembly 5 includes a second drive component 51 and a sealing component 52. The sealing component 52 is movably disposed in the storage hopper 2 and has a first position that blocks the feed inlet 222 and a second position that opens the feed inlet 222. The output end of the second drive component 51 is connected to the sealing component 52 and is used to drive the sealing component 52 to switch between the first and second positions. When it is necessary to replenish material into the receiving cavity 221, the second drive component 51 controls the sealing component 52 to move from the first position to the second position to open the feed inlet 222. After replenishment is completed, the second drive component 51 controls the sealing component 52 to move from the second position to the first position to block the feed inlet 222, ensuring the sealing of the receiving cavity 221 and preventing contamination of the freeze-dried bulbs. The second drive component 51 enables electric control of the opening and closing of the feed inlet 222, improving the degree of automation.

[0079] In this embodiment, the sealing member 52 is slidably disposed on the storage bin 2, and the second driving member 51 is a linear driving member that can drive the sealing member 52 to slide and switch between a first position and a second position. Specifically, a guide rail is provided on the storage bin 2, and a slider is provided on the sealing member 52. The slider is slidably connected to the guide rail to guide the sliding of the sealing member 52 and improve the movement accuracy of the sealing member 52.

[0080] See Figure 2 and Figure 4 A second fixed base 214 is provided on the storage bin 2, and the housing of the second driving member 51 is fixed on the second fixed base 214. A first protrusion 521 is provided on the upper part of the sealing member 52, and the output end of the second driving member 51 is fixedly connected to the first protrusion 521 to drive the sealing member 52 to slide relative to the storage bin 2.

[0081] For example, the second driving member 51 can be a cylinder, and the output rod of the cylinder is fixedly connected to the sealing member 52. In other embodiments, the second driving member 51 can also be a linear driving member such as an electric cylinder.

[0082] See Figure 2 and Figure 4 The storage bin 2 is provided with a third fixed seat 215, and a second guide rod 216 extending along the sliding direction of the sealing member 52 is provided on the third fixed seat 215. A second protrusion 522 is provided on the side of the sealing member 52, and a guide hole is provided on the second protrusion 522. The second guide rod 216 is movably inserted through the guide hole. When the second driving member 51 drives the sealing member 52 to slide, the second guide rod 216 slides with the guide hole, which can further improve the movement stability of the sealing member 52.

[0083] In other alternative embodiments, the sealing element 52 may also be rotatably disposed in the storage bin 2, and the inlet 222 may be blocked or opened by driving the sealing element 52 to rotate.

[0084] Optionally, see Figure 7 and Figure 8 The storage hopper 2 includes a hopper body 21 and a storage body 22. The hopper body 21 has an installation cavity 211, and the storage body 22 is fitted into the installation cavity 211. The storage body 22 has a receiving cavity 221, and the cross-sectional area of ​​the receiving cavity 221 gradually decreases towards the discharge port 223. That is, the receiving cavity 221 is funnel-shaped. When the storage hopper 2 is tilted, the freeze-dried pellets in the receiving cavity 221 are more likely to automatically converge towards the discharge port 223 under their own gravity, improving the pellet discharge efficiency. Furthermore, the above design of the receiving cavity 221 ensures that the freeze-dried pellets in the receiving cavity 221 only flow out of the discharge port 223 when the storage hopper 2 is tilted; when the storage hopper 2 is horizontal and not tilted, the freeze-dried pellets will not flow out. It should be noted that the cross-sectional area here refers to the cross-sectional area of ​​the space containing the receiving cavity 221, not the cross-sectional area of ​​the storage body 22.

[0085] Because freeze-dried pellets are relatively brittle and easily broken, the storage silo 2 is designed as a separate structure. The storage body 22 can be processed separately using a special material, resulting in a smooth inner wall to prevent breakage of the freeze-dried pellets and facilitate subsequent cleaning of the receiving cavity 221, avoiding cross-contamination between different types of freeze-dried pellets. Furthermore, different materials can be used to manufacture the silo body 21 and the storage body 22, reducing the processing cost and difficulty of the storage silo 2. For example, the storage body 22 can be made of stainless steel, ensuring a smooth inner wall.

[0086] In addition, the modular design of the storage bin 2 allows for the replacement of storage bodies 22 with appropriate volumes according to actual needs. That is, multiple storage bodies 22 with different volumes can be made, and the storage body 22 with the required volume can be replaced as needed, without having to replace the entire storage bin 2. This is convenient, quick, and more cost-effective.

[0087] Optionally, see Figure 4 , Figure 7 and Figure 8The storage hopper 2 also includes a cover 24, which is fixedly connected to the opening of the mounting cavity 211 of the hopper body 21. The cover 24 has an opening at the top, which is the feed inlet 222 of the storage hopper 2. The feed hopper 23 is fixed to the opening of the cover 24. When adding material to the receiving cavity 221, simply pour the freeze-dried balls into the feed hopper 23, and the freeze-dried balls will automatically roll from the feed inlet 222 into the receiving cavity 221. The cover 24 ensures that the receiving cavity 221 can only communicate with the outside through the opening of the cover 24, which facilitates the sealing assembly 5 to seal the feed inlet 222, ensuring the airtightness of the receiving cavity 221 and preventing contamination of the freeze-dried balls.

[0088] Optionally, the sealing element 52 of the sealing assembly 5 has an arc-shaped convex surface at the end facing the feed inlet 222, see reference. Figure 8 The opening of the cover 24 is provided with a concave surface 241. When the sealing member 52 is in the first position, the arc-shaped convex surface of the sealing member 52 can fit with the concave surface 241 on the cover 24, ensuring that the feed inlet 222 is tightly sealed.

[0089] Optionally, see Figure 3 , Figure 4 and Figure 8 The freeze-dried pellet feeding device includes a detection element 6 installed in the storage hopper 2. The detection element 6 is used to detect the remaining amount of freeze-dried pellets in the receiving cavity 221. The detection element 6 allows operators to monitor the remaining amount of freeze-dried pellets in the receiving cavity 221, facilitating the determination of the number of freeze-dried pellets to be added to the receiving cavity 221 based on the remaining amount, thereby accurately controlling the feeding amount of freeze-dried pellets. Freeze-dried pellets can be added manually to the feed inlet 222 or automatically by the machine.

[0090] Furthermore, when the detection element 6 detects that the remaining amount of freeze-dried balls in the receiving cavity 221 is lower than a set threshold, the freeze-dried ball feeding equipment can issue a prompt signal to remind the operator to add freeze-dried balls to the receiving cavity 221 in a timely manner, ensuring the continuous operation of the freeze-dried ball feeding equipment. The prompt signal can be in the form of an indicator light or a voice message.

[0091] In this embodiment, the detection element 6 includes an optical fiber detection element, that is, the remaining amount of freeze-dried bulbs in the receiving cavity 221 is determined by optical fiber detection, which has high detection efficiency and accuracy. Specifically, see [reference needed]. Figure 8 The detection element 6 is installed on the cover 24 of the storage bin 2, and the detection end of the detection element 6 is located inside the receiving cavity 221. When the remaining amount of freeze-dried balls in the receiving cavity 221 is insufficient to submerge the material... Figure 8 When the height of the dotted line in the image is reached, the detector 6 cannot detect the freeze-dried balls. At this time, it is determined that the remaining amount of freeze-dried balls is lower than the set threshold, and freeze-dried balls need to be added to the receiving cavity 221.

[0092] For example, the fiber optic detection element is a fiber optic sensor. Its working principle involves sending a light beam incident from a light source through an optical fiber into a modulator. Within the modulator, the light interacts with the external parameters being measured, causing changes in the optical properties of the light, such as intensity, wavelength, frequency, phase, and polarization state, resulting in a modulated optical signal. This signal is then sent through an optical fiber to a photoelectric device and, after passing through a demodulator, the measured parameters are obtained. Fiber optic sensors offer high detection sensitivity and good reliability.

[0093] In other embodiments, the detection element 6 may also be an infrared sensor or the like, which detects the remaining amount of freeze-dried bulbs in the receiving cavity 221.

[0094] Optionally, see Figure 2 and Figure 3 The freeze-dried pellet feeding equipment includes a cutting device 7 installed at the discharge port 223 of the storage silo 2. The cutting device 7 can selectively separate or connect the discharge port 223 with the feed silo of the freeze-dried pellet dispensing equipment 10. That is, only when the cutting device 7 connects the discharge port 223 with the feed silo can the freeze-dried pellets in the receiving cavity 221 enter the feed silo, and the freeze-dried pellets can be quantitatively replenished into the feed silo to accurately control the replenishment amount.

[0095] Specifically, see Figure 5 and Figure 8 The material cutting device 7 includes a material cutting bin 71 and a blocking member 72. The material cutting bin 71 has a material cutting cavity 711 that connects the discharge port 223 and the feed bin. The blocking member 72 is movably disposed in the material cutting bin 71 and has a blocking position and an open position. In the blocking position, the blocking member 72 extends into the material cutting cavity 711 to separate the discharge port 223 from the feed bin. In the open position, the blocking member 72 moves out of the material cutting cavity 711 to connect the discharge port 223 and the feed bin.

[0096] Initially, the storage bin 2 is horizontal, and the blocking member 72 is in the blocking position. When the first driving member 3 drives the storage bin 2 to tilt at a certain angle, a portion of the freeze-dried balls in the receiving cavity 221 will enter the cutting cavity 711 from the discharge port 223. When the storage bin 2 is adjusted back to a horizontal state, this portion of freeze-dried balls will be temporarily stored in the cutting cavity 711. At this time, the blocking member 72 is then driven to the open position, and the freeze-dried balls in the cutting cavity 711 can enter the feeding bin of the freeze-dried ball dispensing device 10. That is, each time the freeze-dried ball feeding device operates, it replenishes the freeze-dried ball dispensing device 10 with a fixed amount of freeze-dried balls that can be contained in the cutting cavity 711, realizing quantitative replenishment of the feeding bin, accurately controlling the amount of freeze-dried balls fed, preventing jamming of the freeze-dried ball dispensing device 10, ensuring the continuity of freeze-dried ball dispensing production, and improving the efficiency of freeze-dried ball dispensing. Understandably, since the freeze-dried pellets are temporarily stored in the cutting chamber 711 before entering the feeding hopper, the volume of the cutting chamber 711 determines the number of freeze-dried pellets entering the feeding hopper. In other words, by setting the cutting chamber 711, a quantitative feeding of the feeding hopper can be achieved.

[0097] Furthermore, the material cutting device 7 also includes a third driving member 73 and an air blowing mechanism 74. The third driving member 73 is connected to the blocking member 72 and is used to drive the blocking member 72 to switch between a blocking position and an open position, thereby realizing electrically controlled movement of the blocking member 72 and improving the degree of automation. The air outlet of the air blowing mechanism 74 is connected to the material cutting chamber 711 and is located near the discharge port 223 in the material cutting chamber 711. The air blowing mechanism 74 is used to blow air into the material cutting chamber 711 to drive the freeze-dried balls smoothly into the feeding bin of the freeze-dried ball dispensing device 10, thereby improving the efficiency of freeze-dried ball dispensing.

[0098] See Figure 2 The housing of the third driving member 73 is fixed to the second fixed seat 214 on the storage bin 2. The cutting bin 71 is provided with a through hole communicating with the cutting cavity 711. The blocking member 72 is movably inserted into the through hole. The third driving member 73 drives the blocking member 72 to move linearly within the through hole, so that the blocking member 72 extends into or moves out of the cutting cavity 711. Exemplarily, the third driving member 73 is a cylinder, and the output rod of the cylinder is fixedly connected to the blocking member 72; the blowing mechanism 74 is exemplarily an air pump, as long as it can generate a stable airflow.

[0099] See Figure 8 The cross-sectional area of ​​the material receiving chamber 711 gradually increases in the direction away from the discharge port 223, causing the inner wall of the material receiving chamber 711 to be inclined. This facilitates the automatic rolling of the freeze-dried balls into the material receiving chamber 711, where they can be temporarily stored. Simultaneously, after the blocking member 72 switches to the open position, the freeze-dried balls can automatically roll down the inclined wall and detach from the material receiving chamber 711. Furthermore, because the inclination direction of the inner wall of the material receiving chamber 711 is opposite to that of the inner wall of the receiving chamber 221, the freeze-dried balls can be temporarily stored in the metering chamber 12 without flowing back into the feeding hopper 20. It should be noted that the cross-sectional area here refers to the cross-sectional area of ​​the space containing the material receiving chamber 711, not the cross-sectional area of ​​the material receiving hopper 71.

[0100] Furthermore, various specifications of cutting bins 71 can be set up. By changing the cutting bins 71, the single feeding amount of freeze-dried balls can be changed, thus expanding the applicability of the freeze-dried ball feeding equipment.

[0101] Optionally, see Figure 1 , Figure 2 and Figure 5 The freeze-dried pellet feeding device also includes a conveying pipe 8, one end of which is connected to a cutting device 7, and the other end is connected to the feed hopper of the freeze-dried pellet dispensing device 10. When the blocking component 72 is switched to the open position, the freeze-dried pellets in the cutting chamber 711 roll into the conveying pipe 8 under their own gravity and enter the feed hopper of the freeze-dried pellet dispensing device 10 along the conveying pipe 8. The conveying pipe 8 can guide the freeze-dried pellets into the feed hopper and ensure that the freeze-dried pellets are in a closed environment during the feeding process, preventing contamination of the freeze-dried pellets. Figure 8 As shown, the material cutting bin 71 is provided with an interface that communicates with the material cutting chamber 711, and the material conveying pipe 8 is connected to this interface.

[0102] Optionally, see Figure 1 Multiple storage bins 2 are installed on the fixed frame 1. These bins 2 are connected one-to-one with multiple freeze-dried pellet dispensing devices 10 to feed the pellets into each device, improving feeding efficiency. Each freeze-dried pellet dispensing device 10 is also connected to a freeze-dried pellet filling device 20 below it. The filling device 20 has a discharge nozzle that is inserted into a container 30 storing the freeze-dried pellets. The receiving cavities 221 of the multiple storage bins 2 can contain the same type of freeze-dried pellets, allowing the multiple filling devices 20 to simultaneously dispense freeze-dried pellets into multiple containers 30, improving filling efficiency. Different types of freeze-dried pellets can also be added to the receiving cavities 221 of the multiple storage bins 2, allowing the multiple filling devices 20 to output different types of freeze-dried pellets. When loading pellets into different types of reaction plates, one of the filling devices 20 can be selected to load pellets into the corresponding type of reaction plate, broadening its applicability.

[0103] In this embodiment, the freeze-dried pellet feeding device includes a control module. The first drive component 3, the second drive component 51, the third drive component 73, the air blowing mechanism 74, and the detection component 6 are all communicatively connected to the control module. The control module can control the opening and closing of the first drive component 3, the second drive component 51, the third drive component 73, and the air blowing mechanism 74 according to the information detected by the detection component, so as to realize automated control of freeze-dried pellet feeding.
