[0051] In order 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 in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. Among them, the terms "first position" and "second position" are two different positions.

[0053] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0054] like Figures 1 to 5As shown, this embodiment provides a freeze-dried ball feeding device, which can prevent freeze-dried balls from being damaged and ensure the quality of freeze-dried balls. The freeze-dried ball feeding device includes a fixed frame 1, a storage bin 2 and a first driving member 3.

[0055] Among them, see Figure 1 , Figure 2 , Figure 3 and Figure 8 The storage bin 2 is swingably arranged on the fixed frame 1, and the storage bin 2 has a receiving chamber 221 for containing freeze-dried balls, and the receiving chamber 221 has a discharge port 223, and the discharge port 223 can be connected to the feed bin of the freeze-dried ball dispensing device 10. The first driving member 3 is arranged on the fixed frame 1, and the output end of the first driving member 3 can act on the storage bin 2, and drive the storage bin 2 to swing and tilt at a preset angle relative to the fixed frame 1, so that the freeze-dried balls in the receiving chamber 221 can fall into the feed bin of the freeze-dried ball dispensing device 10 through the discharge port 223.

[0056] The freeze-dried ball feeding device provided in this embodiment controls the first driving member 3 to drive the storage bin 2 to swing and tilt relative to the fixed frame 1 at a preset angle (such as Figure 5 As shown), the accommodating chamber 221 of the storage bin 2 is tilted relative to the horizontal plane. At this time, the freeze-dried balls in the accommodating chamber 221 can roll toward the discharge port 223 under the action of their own gravity, and roll down to the feed bin of the freeze-dried ball dispensing device 10 through the discharge port 223. That is, the freeze-dried ball loading device only needs to control the storage bin 2 to tilt at a certain angle through the first driving member 3, so that the freeze-dried balls can automatically enter the feed bin of the freeze-dried ball dispensing device 10, realize automatic loading to the freeze-dried ball dispensing device 10, and improve the loading efficiency of the freeze-dried balls. In addition, the loading method of tilting the storage bin 2 to make the freeze-dried balls automatically fall can avoid the freeze-dried balls from being damaged due to vibration, prevent the freeze-dried balls from being damaged, ensure the quality of the freeze-dried balls after packaging, 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 that are relatively arranged, the first end being a connection end, and the second end being a free end, such as, the first end of the storage bin 2 is rotatably connected to the fixed frame 1, and 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 is lifted and lowered 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 is lifted and lowered relative to the fixed frame 1, thereby making the storage bin 2 tilted relative to the fixed frame 1 at a preset angle. Specifically, when the output end of the first driving member 3 rises, an upward force can be applied 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 of the storage bin 2 as a free end can rise relative to the first end, causing the storage bin 2 to tilt relative to the fixed frame 1, so that the terrain at the discharge port 223 becomes relatively low, and the freeze-dried balls in the accommodating chamber 221 can roll down to the discharge port 223 under the action of their own gravity, so that the freeze-dried balls automatically fall to the feed bin of the freeze-dried ball dispensing device 10. By adjusting the tilt angle of the storage bin 2 by lifting, the driving structure is simple and easy to implement, and the lifting drive is stable, which can prevent the freeze-dried balls from breaking to the greatest extent and ensure the quality of the freeze-dried balls after packaging.

[0058] Exemplarily, the first driving member 3 can be a cylinder, the output rod of which is movably connected to the storage bin 2, and the storage bin 2 is tilted at a certain angle by lifting the second end of the storage bin 2. In other embodiments, the first driving member 3 can also be a linear driving member such as an electric cylinder, a linear motor, a screw nut mechanism, etc.

[0059] The above-mentioned preset angle can be determined according to the actual feeding amount of the freeze-dried balls. For example, if the feeding amount of the freeze-dried balls is large, the first driving member 3 can be controlled to be lifted to a higher height so that the storage bin 2 is tilted at a larger angle; if the feeding amount of the freeze-dried balls is small, the first driving member 3 can be controlled to be lifted to a smaller height so that the storage bin 2 is tilted at a smaller angle.

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

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

[0062] Exemplarily, the rolling element 31 is a roller, see Figure 3 and Figure 4A connecting block 32 is provided at the output end of the first driving member 3, and a connecting shaft is rotatably provided on the connecting block 32. A roller is provided at each end of the connecting shaft. The two rollers roll with the storage bin 2 at the same time, which can improve the matching stability of the first driving member 3 and the storage bin 2.

[0063] In other embodiments, the output end of the first driving member 3 may also be slidably connected to the material storage bin 2. During the lifting process of the first driving member 3, the output end of the first driving member 3 adaptively slides relative to the material storage bin 2, thereby preventing the material storage bin 2 from interfering with the lifting of the first driving member 3. Specifically, a slider may be provided at the output end of the first driving member 3, and correspondingly, a slide groove extending along the tilting direction of the material storage bin 2 may be provided on the material storage bin 2, and the slider and the slide groove may be slidably matched.

[0064] Optionally, see Figure 2 and Figure 3 The freeze-dried ball feeding device also includes an elastic member 4, one end of which is connected to the fixed frame 1, and the other end is connected to the storage bin 2. The rolling body 31 can always contact the outer peripheral surface of the storage bin 2 under the elastic force of the elastic member 4. That is, the elastic member 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 body 31, ensuring that the rolling body 31 can always roll with the outer peripheral surface of the storage bin 2 during the lifting and lowering process of the first driving member 3, thereby improving the stability of the storage bin 2 during the tilting process. At the same time, the setting of the elastic member 4 can limit the maximum rising height of the second end of the storage bin 2, and prevent the storage bin 2 from tilting excessively and causing overturning.

[0065] In addition, the elastic member 4 also has a reset function on the storage bin 2, so that the storage bin 2 can move downward and reset to a horizontal position. Specifically, when the first driving member 3 descends, the storage bin 2 can descend under the pulling force of the elastic member 4, so that the storage bin 2 automatically resets.

[0066] Exemplarily, the elastic member 4 is a tension spring. Figure 3 A first connecting plate 113 is provided on the fixing frame 1, and a second connecting plate 213 is provided on the storage bin 2. Hooks are provided at both ends of the tension spring. Hanging holes are provided on the first connecting plate 113 and the second connecting plate 213. The hooks are hooked on the corresponding hanging holes to ensure that the tension spring is reliably connected to the fixing frame 1 and the storage bin 2 and is easy to disassemble.

[0067] Of course, in other embodiments, the elastic member 4 may not be provided. For example, the rolling element 31 at the output end of the first driving member 3 is rollingly matched with and connected to the material storage bin 2, or the output end of the first driving member 3 is slidingly connected to the material storage bin 2, and the output end of the first driving member 3 drives the material storage bin 2 to move together when it is raised or lowered, so that the material storage bin 2 can be tilted to a preset angle and can also be reset.

[0068] Optionally, see Figure 3A guide cylinder 1221 is provided on the fixing 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 slidably cooperates with the guide cylinder 1221. When the first driving member 3 drives the second end of the storage bin 2 to rise and fall, the first guide rod 212 always slidably cooperates with the guide cylinder 1221, so that the storage bin 2 can be prevented from being deflected during the lifting process, and the stability of the storage bin 2 during the tilting process can be further improved.

[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 driving member 3 is arranged on the base 11, and the storage bin 2 is rotatably arranged on the support frame 12. The base 11 can be fixed on the base of the freeze-dried ball packaging production line to set the freeze-dried ball feeding device above the freeze-dried ball dispensing device 10. The support frame 12 can set the storage bin 2 above the first driving member 3, provide a lifting space for the first driving member 3, and facilitate the first driving member 3 to lift and lower to adjust the inclination angle of the storage bin 2.

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

[0071] See also Figure 2 , Figure 4 and Figure 5 The support frame 12 of the fixing frame 1 is provided with a connecting seat 1222, and a connecting ear is protruded from the connecting seat 1222. Figure 6 A rotating groove 217 is provided on the storage bin 2, 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 supporting frame 12.

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

[0073] Optionally, see Figure 2 and Figure 4, a mounting seat 111 with an adjustable tilt angle is provided on the fixed frame 1, and the housing of the first driving member 3 is fixed to the mounting seat 111. The maximum tilt angle of the storage bin 2 can be adjusted by adjusting the tilt angle of the mounting seat 111. When the tilt angle of the mounting seat 111 relative to the fixed frame 1 changes, the lifting direction of the first driving member 3 changes accordingly, so that the maximum rising height of the output end of the first driving member 3 in the vertical direction can be changed, and the maximum tilt angle of the storage bin 2 can be adjusted. Before the freeze-dried balls are loaded, the tilt angle of the mounting seat 111 relative to the fixed frame 1 can be adjusted accordingly according to the freeze-dried balls loading requirements, so that the maximum tilt angle of the storage bin 2 meets the requirements.

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

[0075] Optionally, see Figure 2 , Figure 3 and Figure 4 The storage bin 2 has a feed port 222, and the freeze-dried ball feeding device further includes a sealing assembly 5 disposed at the feed port 222, and the sealing assembly 5 is used to block or open the feed port 222. When the freeze-dried balls are fed, the feed port 222 is opened by the sealing assembly 5, and after a certain amount of freeze-dried balls are loaded into the accommodating chamber 221, the feed port 222 is blocked by the sealing assembly 5, which can prevent external dust and debris from entering the accommodating chamber 221, and ensure that the freeze-dried balls will not be contaminated.

[0076] Continue reading Figure 2 , Figure 3 and Figure 4 The storage bin 2 is provided with a feed hopper 23 at the feed inlet 222. The feed hopper 23 has a guiding slope for guiding the freeze-dried balls to the feed inlet 222. The provision of the feed hopper 23 can expand the feeding space, which is more conducive to adding freeze-dried balls into the accommodating chamber 221, improving the efficiency of loading the freeze-dried balls, and preventing the freeze-dried balls from falling to the outside. By providing a guiding slope on the feed hopper 23, it is more conducive to the freeze-dried balls rolling from the feed inlet 222 to the accommodating chamber 221, further improving the efficiency of loading the freeze-dried balls. Specifically, refer to Figure 4 The guide slope is inclined downward in a direction close to the feed port 222.

[0077] Exemplarily, the feed hopper 23 is in the shape of a bucket. In other embodiments, the feed hopper 23 may also be in the shape of a funnel.

[0078] Optionally, see Figure 3 and Figure 4 , the sealing assembly 5 includes a second driving member 51 and a sealing member 52, the sealing member 52 is movably arranged in the storage bin 2, and has a first position for blocking the feed port 222 and a second position for opening the feed port 222, and the output end of the second driving member 51 is connected to the sealing member 52, and is used to drive the sealing member 52 to switch between the first position and the second position. When it is necessary to add material to the accommodating chamber 221, the sealing member 52 is controlled by the second driving member 51 to move from the first position to the second position to open the feed port 222. After the feeding is completed, the sealing member 52 is controlled by the second driving member 51 to move from the second position to the first position to block the feed port 222, ensure the closedness of the accommodating chamber 221, and prevent the contamination of the freeze-dried balls. The setting of the second driving member 51 can realize the opening and closing of the feed port 222 by electrically controlling the feeding port, thereby 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, which can drive the sealing member 52 to slide and switch between the first position and the second position. Specifically, a guide rail is disposed on the storage bin 2, and a slider is disposed on the sealing member 52. The slider is slidably connected to the guide rail to guide the sliding of the sealing member 52, thereby improving the movement accuracy of the sealing member 52.

[0080] See also Figure 2 and Figure 4 The storage bin 2 is provided with a second fixing seat 214, and the housing of the second driving member 51 is fixed on the second fixing seat 214. A first protrusion 521 is protruded above 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] Exemplarily, the second driving member 51 may 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 may also be a linear driving member such as an electric cylinder.

[0082] See also Figure 2 and Figure 4 A third fixed seat 215 is provided on the storage bin 2, 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 convexly provided on the side of the sealing member 52, and the second protrusion 522 is provided with a guide hole. The second guide rod 216 is movably inserted into 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 to further improve the movement stability of the sealing member 52.

[0083] In other optional embodiments, the sealing member 52 may also be rotatably disposed on the storage bin 2 , and the feed port 222 may be blocked or opened by driving the sealing member 52 to rotate.

[0084] Optionally, see Figure 7 and Figure 8 The storage bin 2 includes a bin body 21 and a storage body 22. The bin body 21 is provided with an installation cavity 211. The storage body 22 is embedded in the installation cavity 211. The storage body 22 is provided with a receiving cavity 221, and the cross-sectional area of ​​the receiving cavity 221 gradually decreases along the direction close to the discharge port 223. That is, the receiving cavity 221 is funnel-shaped. When the storage bin 2 is tilted, the freeze-dried balls in the receiving cavity 221 are more likely to automatically gather at the discharge port 223 under the action of their own gravity, which can improve the ball falling efficiency. In addition, the above-mentioned design of the receiving cavity 221 makes it possible for the freeze-dried balls in the receiving cavity 221 to flow out from the discharge port 223 only when the storage bin 2 is tilted, and when the storage bin 2 is horizontal and not tilted, the freeze-dried balls will not flow out. It should be noted that the cross-sectional area here refers to the cross-sectional area of ​​the space where the receiving cavity 221 is located, rather than the cross-sectional area of ​​the storage body 22.

[0085] Since the freeze-dried ball itself is relatively brittle and easily broken, the storage bin 2 is designed as a split structure, and the storage body 22 can be processed with a special material alone, so that the inner wall of the storage body 22 is relatively smooth, and the freeze-dried ball is prevented from being damaged, and it is convenient to clean up the accommodating chamber 221 in the later stage, and cross contamination of freeze-dried balls of different types is avoided. In addition, different materials can be used to make the warehouse body 21 and the storage body 22, reducing the processing cost and processing difficulty of the storage bin 2. Exemplarily, the storage body 22 can be made of stainless steel, and the inner wall of the storage body 22 can be guaranteed to be smooth.

[0086] In addition, the split structure design of the storage bin 2 can also replace the storage body 22 of appropriate volume according to actual needs, that is, multiple storage bodies 22 with different volumes can be made, and the storage body 22 of the current required volume can be replaced according to needs, without replacing the entire storage bin 2 as a whole, which is convenient, fast and more cost-saving.

[0087] Optionally, see Figure 4 , Figure 7 and Figure 8The storage bin 2 further includes a cover 24, which is fixedly connected to the cavity opening of the mounting cavity 211 of the bin body 21, and has an opening above the cover 24, which is the feed port 222 of the storage bin 2, and the feed hopper 23 is fixed to the opening of the cover 24. When feeding into the receiving chamber 221, it is only necessary to pour the freeze-dried balls into the feed hopper 23, and the freeze-dried balls can automatically roll from the feed port 222 to the receiving chamber 221. The setting of the cover 24 makes it possible for the receiving chamber 221 to communicate with the outside only through the opening of the cover 24, so that the sealing assembly 5 can block the feed port 222, ensure the sealing of the receiving chamber 221, and prevent the freeze-dried balls from being contaminated.

[0088] Optionally, the sealing member 52 of the sealing assembly 5 has an arc-shaped convex surface at one end facing the feed port 222, see Figure 8 An inner concave surface 241 is provided at the opening of the sealing cover 24. When the sealing member 52 is in the first position, the arcuate convex surface of the sealing member 52 can fit with the inner concave surface 241 on the sealing cover 24 to ensure that the feed port 222 is tightly sealed.

[0089] Optionally, see Figure 3 , Figure 4 and Figure 8 The freeze-dried ball feeding device includes a detection member 6 disposed in the storage bin 2, and the detection member 6 is used to detect the remaining amount of freeze-dried balls in the accommodating chamber 221. The setting of the detection member 6 enables the staff to grasp the remaining amount of freeze-dried balls in the accommodating chamber 221, and is convenient for determining the number of freeze-dried balls to be added to the accommodating chamber 221 according to the remaining amount of freeze-dried balls, thereby accurately controlling the amount of freeze-dried balls fed. The freeze-dried balls can be added to the feed port 222 manually, or the machine can automatically add the freeze-dried balls to the feed port 222.

[0090] Furthermore, when the detection member 6 detects that the amount of the freeze-dried balls in the accommodating chamber 221 is lower than a set threshold, the freeze-dried ball feeding device can send a prompt signal to prompt the staff to add freeze-dried balls to the accommodating chamber 221 in time to ensure the working continuity of the freeze-dried ball feeding device. The prompt signal can be in the form of an indicator light or in the form of voice.

[0091] In this embodiment, the detection element 6 includes an optical fiber detection element, that is, the amount of the freeze-dried balls remaining in the accommodating cavity 221 is determined by optical fiber detection, and the detection efficiency is high and the detection is accurate. Figure 8 The detection member 6 is installed on the cover 24 of the storage bin 2, and the detection end of the detection member 6 is located in the accommodating chamber 221. When the remaining amount of the freeze-dried balls in the accommodating chamber 221 is not enough to cover the freeze-dried balls, the detection member 6 is installed on the cover 24 of the storage bin 2, and the detection end of the detection member 6 is located in the accommodating chamber 221. Figure 8 When the height of the dotted line in the figure is reached, the detection element 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 value, and freeze-dried balls need to be added to the accommodating chamber 221.

[0092] For example, the optical fiber detection element is an optical fiber sensor, whose working principle is to send the incident light beam from the light source into the modulator through the optical fiber, and interact with the external measured parameters in the modulator to change the optical properties of the light, such as the intensity, wavelength, frequency, phase, polarization state, etc., to become a modulated optical signal, which is then sent to the optoelectronic device through the optical fiber and obtained after the demodulator. The optical fiber sensor has high detection sensitivity and good reliability.

[0093] In other embodiments, the detection member 6 may also be an infrared sensor, etc., and the remaining amount of the freeze-dried balls in the containing cavity 221 is detected by the infrared sensor.

[0094] Optionally, see Figure 2 and Figure 3 The freeze-dried ball feeding device includes a material cutting device 7 disposed at the discharge port 223 of the storage bin 2, and the material cutting device 7 can selectively separate or connect the discharge port 223 and the feed bin of the freeze-dried ball dispensing device 10. That is, only when the material cutting device 7 connects the discharge port 223 and the feed bin, the freeze-dried balls in the accommodating cavity 221 can enter the feed bin, and the freeze-dried balls can be quantitatively added to the feed bin, and the amount of feeding can be accurately controlled.

[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 connecting the material outlet 223 and the material feeding bin. The blocking member 72 is movably arranged on the material cutting bin 71 and has a blocking position and an opening position. When in the blocking position, the blocking member 72 extends into the material cutting cavity 711 to separate the material outlet 223 from the material feeding bin. When in the opening position, the blocking member 72 moves out of the material cutting cavity 711 to connect the material outlet 223 and the material feeding bin.

[0096] In the initial state, 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 part of the freeze-dried balls in the accommodating chamber 221 will enter the material cutting chamber 711 from the discharge port 223. When the storage bin 2 is adjusted to a horizontal state again, the part of the freeze-dried balls will be temporarily stored in the material cutting chamber 711. At this time, the blocking member 72 is driven to move to the open position, and the freeze-dried balls in the material cutting chamber 711 can enter the feed bin of the freeze-dried ball dispensing device 10. That is, each time the freeze-dried ball feeding device moves, the freeze-dried ball dispensing device 10 is replenished with a certain amount of freeze-dried balls that can be accommodated in the material cutting chamber 711, so as to realize the quantitative feeding of the feed bin, accurately control the amount of freeze-dried balls fed, prevent the freeze-dried ball dispensing device 10 from getting stuck, ensure the continuity of the freeze-dried ball packaging production work, and improve the freeze-dried ball packaging efficiency. It is understandable that since the freeze-dried balls will temporarily store in the cutting chamber 711 before entering the feed bin, the volume of the cutting chamber 711 determines the number of freeze-dried balls entering the feed bin, that is, by setting the cutting chamber 711, quantitative feeding to the feed bin can be achieved.

[0097] Furthermore, the material cutting device 7 also includes a third driving member 73 and a 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 the blocking position and the open position, so as to realize the electric control of the movement of the blocking member 72 and improve the degree of automation. The air outlet end of the blowing mechanism 74 is connected to the material cutting chamber 711 and is located at a position of the material cutting chamber 711 close to the discharge port 223. The blowing mechanism 74 is used to blow air into the material cutting chamber 711 to drive the freeze-dried balls to smoothly enter the feed bin of the freeze-dried ball dispensing device 10, thereby improving the efficiency of the freeze-dried balls falling.

[0098] See also Figure 2 The housing of the third driving member 73 is fixed on the second fixing seat 214 on the material storage bin 2, and the material cutting bin 71 is provided with a through hole communicating with the material cutting chamber 711, and the blocking member 72 is movably arranged in the through hole, and the third driving member 73 drives the blocking member 72 to move linearly in the through hole, so that the blocking member 72 extends into the material cutting chamber 711 or moves out of the material cutting chamber 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 also Figure 8 , the cross-sectional area of ​​the cutting chamber 711 gradually increases in the direction away from the discharge port 223, so that the inner wall surface of the cutting chamber 711 is inclined, which is convenient for the freeze-dried balls to automatically roll down to the cutting chamber 711 and temporarily store in the cutting chamber 711. At the same time, after the blocking member 72 is switched to the open position, the freeze-dried balls can automatically roll down along the inclined wall surface and leave the cutting chamber 711. In addition, since the inclination direction of the inner wall surface of the cutting chamber 711 is opposite to the inclination direction of the inner wall of the accommodating chamber 221, the freeze-dried balls can be temporarily stored in the quantitative cavity 12 without flowing back to the upper bin 20. It should be noted that the cross-sectional area here refers to the cross-sectional area of ​​the space where the cutting chamber 711 is located, rather than the cross-sectional area of ​​the cutting bin 71.

[0100] Furthermore, material cut-off bins 71 of various specifications may be provided, and the single loading amount of freeze-dried balls may be changed by replacing the material cut-off bins 71, thereby expanding the application scope of the freeze-dried ball loading equipment.

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

[0102] Optionally, see Figure 1 , a plurality of storage bins 2 are installed on the fixed frame 1, and the plurality of storage bins 2 are used to be connected with the plurality of freeze-dried ball dispensing devices 10 in a one-to-one correspondence, and to respectively feed the plurality of freeze-dried ball dispensing devices 10, thereby improving the feeding efficiency. A freeze-dried ball dispensing device 20 is also connected below each freeze-dried ball dispensing device 10, and the freeze-dried ball dispensing device 20 has a discharge nozzle, and the discharge nozzle is used to be inserted into a container 30 for storing freeze-dried balls. Among them, the same type of freeze-dried balls can be added to the accommodating chambers 221 of the plurality of storage bins 2, so that the plurality of freeze-dried ball dispensing devices 20 can simultaneously dispense freeze-dried balls into the plurality of containers 30, thereby improving the freeze-dried ball dispensing efficiency. Different types of freeze-dried balls can also be added to the accommodating chambers 221 of the plurality of storage bins 2, so that the plurality of freeze-dried ball dispensing devices 20 can respectively output different types of freeze-dried balls. When planting balls into different types of reaction disks, one of the freeze-dried ball dispensing devices 20 can be selected to plant balls into the corresponding type of reaction disk, and the scope of application is wider.

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