Description

Technical Field

[0001] This invention relates to the field of automated production equipment technology, and in particular to a freeze-dried pellet quantitative feeding device and freeze-dried pellet feeding equipment. Background Technology

[0002] Freeze-dried bulbs are small, solid spheres formed by rapidly freezing liquid nitrogen at extremely low temperatures using a specialized precision micro-pump. They are primarily used in medical diagnostics and skincare. During the production of freeze-dried bulbs, after forming, they need to be quickly dispensed into sealed containers or onto reaction discs for subsequent biochemical reactions or testing.

[0003] In existing technologies, on automated freeze-dried pellet packaging production lines, freeze-dried pellets are typically fed using a vibratory feeder, which can easily damage the pellets. Furthermore, the current feeding method cannot accurately control the amount of freeze-dried pellets fed at one time; excessive feeding can cause jamming in the next process's pellet dispensing equipment, thus affecting the packaging efficiency.

[0004] Therefore, there is an urgent need for a quantitative feeding device and equipment for freeze-dried pellets to solve the above problems. Summary of the Invention

[0005] Based on the above problems, the purpose of this invention is to provide a quantitative feeding device and equipment for freeze-dried balls, which can prevent damage to freeze-dried balls and accurately control the amount of freeze-dried balls fed at one time, thereby ensuring the efficiency of freeze-dried ball packaging.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] On one hand, a quantitative feeding device for freeze-dried pellets is provided for connection to a freeze-dried pellet feeding device and a freeze-dried pellet dispensing device. The freeze-dried pellet feeding device includes a feeding hopper, and the freeze-dried pellet dispensing device includes a feeding hopper. The quantitative feeding device for freeze-dried pellets includes:

[0008] A material cutting bin, wherein the material cutting bin has a material cutting chamber;

[0009] The blocking mechanism includes a blocking member movably disposed in the cutting bin, the blocking member having a first position and a second position;

[0010] In the first position, the blocking member extends into the cutting chamber and divides the cutting chamber into a first chamber and a second chamber that are independent of each other. The first chamber is used to communicate with the feeding hopper, and the second chamber is used to communicate with the feeding hopper.

The cutting bin body is provided with the cutting cavity. The quantitative component is installed in the first chamber of the cutting cavity. The quantitative component has an inner cavity with a first inlet and a first outlet. The first inlet is connected to the feeding bin. When the blocking component is in the first position, it blocks the first outlet.

[0013] The cross-sectional area of ​​the inner cavity of the metering element gradually increases from the first inlet to the first outlet.

[0014] As an optional embodiment of the freeze-dried pellet quantitative feeding device of the present invention, the quantitative component can be detachably installed in the first chamber.

[0015] As an optional embodiment of the freeze-dried pellet quantitative feeding device of the present invention, the cutting bin is provided with a discharge port at the bottom of the second chamber, and the discharge port is not higher than the first outlet; the discharge port is connected to the feeding bin of the freeze-dried pellet dispensing device through a conveying pipe;

[0016] And / or, the material cutting hopper is provided with an observation port on the side of the second chamber opposite to the first chamber, and the observation port is provided with an observation window for observing the situation inside the material cutting chamber.

[0017] As an optional embodiment of the freeze-dried pellet quantitative feeding device of the present invention, the freeze-dried pellet quantitative feeding device further includes an air blowing mechanism, the air outlet of which is connected to the material cutting chamber and is used to feed the freeze-dried pellets in the material cutting chamber into the feeding bin.

[0018] As an optional embodiment of the freeze-dried pellet quantitative feeding device of the present invention, the cutting bin is provided with an air inlet channel communicating with the cutting chamber. The air inlet channel has a second inlet and a second outlet. The second inlet is connected to the air outlet end of the blowing mechanism, and the second outlet is located at one end of the cutting chamber near the feeding bin of the freeze-dried pellet feeding device.

[0019] As an optional embodiment of the freeze-dried pellet quantitative feeding device of the present invention, the blocking mechanism further includes a first driving member, the material cutting bin is provided with a guide channel communicating with the material cutting cavity, the blocking member is movably inserted through the guide channel, and the output end of the first driving member is connected to the blocking member to drive the blocking member to switch between the first position and the second position.

[0020] On the other hand, a freeze-dried pellet feeding device is provided, including a fixed frame, a feeding bin, a second driving component, and the aforementioned freeze-dried pellet quantitative feeding device. The feeding bin is rotatably disposed on the fixed frame. The output end of the second driving component is movably connected to the feeding bin and is used to drive the feeding bin to tilt relative to the fixed frame at a preset angle. The freeze-dried pellet quantitative feeding device is disposed at the discharge end of the feeding bin.

[0021] As an optional embodiment of the freeze-dried pellet feeding device of the present invention, the output end of the second drive member is provided with a rotatable rolling body, which can roll and cooperate with the outer peripheral surface of the feeding bin; or, the output end of the second drive member is slidably connected to the feeding bin.

[0022] As an optional solution for the freeze-dried ball feeding device of the present invention, the freeze-dried ball feeding device further includes an elastic element, one end of which is connected to the fixed frame and the other end of which is connected to the feeding bin, and the rolling body can always be in contact with the outer peripheral surface of the feeding bin under the elastic force of the elastic element.

[0023] And / or, the fixed frame is provided with a guide cylinder, and the feeding hopper is provided with a first guide rod, the first guide rod being inserted into the guide cylinder and slidingly engaged with the guide cylinder.

[0024] The beneficial effects of this invention are as follows:

[0025] The present invention provides a quantitative feeding device for freeze-dried pellets. The feeding hopper of the freeze-dried pellet feeding device stores freeze-dried pellets. Before the freeze-dried pellet feeding device is activated, the blocking member is in a first position, and the first chamber and the second chamber are independent of each other; that is, the feeding hopper of the freeze-dried pellet feeding device is not connected to the feeding hopper of the freeze-dried pellet dispensing device. After the freeze-dried pellet feeding device is activated, the freeze-dried pellets in the feeding hopper can only enter the first chamber and be temporarily stored there; that is, the first chamber can temporarily store a certain amount of freeze-dried pellets. When the blocking member switches from the first position to the second position, the first chamber, the second chamber, and the feeding hopper are connected. The freeze-dried pellets temporarily stored in the first chamber enter the feeding hopper of the freeze-dried pellet dispensing device through the second chamber, completing the quantitative feeding of the freeze-dried pellets to the dispensing device. That is, each time the freeze-dried pellet feeding equipment operates, it replenishes the freeze-dried pellet dispensing equipment with a fixed amount of freeze-dried pellets that can be contained in the first chamber, thereby achieving quantitative feeding of freeze-dried pellets to the dispensing equipment. This accurately controls the amount of freeze-dried pellets fed at one time, prevents jamming of the freeze-dried pellet dispensing equipment, ensures the continuity of freeze-dried pellet dispensing production, and improves the efficiency of freeze-dried pellet dispensing.

[0026] The freeze-dried pellet feeding device provided by the present invention drives the feeding bin to rotate relative to the fixed frame by a preset angle through the second driving component, so that the feeding bin tilts at a certain angle, and the freeze-dried pellets in the feeding bin roll into the first chamber of the cutting chamber under their own gravity, realizing automatic feeding of freeze-dried pellets, avoiding damage to freeze-dried pellets due to vibration, preventing damage to freeze-dried pellets, and ensuring the quality of freeze-dried pellets after packaging.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0059] Example 1

[0060] like Figures 1 to 5 As shown, this embodiment provides a freeze-dried pellet quantitative feeding device for connecting with freeze-dried pellet feeding equipment and freeze-dried pellet dispensing equipment. It can prevent freeze-dried pellets from being damaged and accurately control the single feeding amount of freeze-dried pellets, ensuring the continuity of freeze-dried pellet dispensing production and improving freeze-dried pellet dispensing efficiency.

[0061] Among them, see Figure 1 , Figure 2 and Figure 3 The freeze-dried pellet feeding equipment includes a feeding hopper of 20 (e.g., Figure 8 As shown), the freeze-dried pellet dispensing equipment includes a feeding hopper, and the freeze-dried pellet quantitative feeding device includes a cutting hopper 1 and a blocking mechanism 2. The cutting hopper 1 has a cutting chamber 111, and the blocking mechanism 2 includes a blocking member 21 movably disposed in the cutting hopper 1, the blocking member 21 having a first position and a second position. Figure 2As shown, in the first position, the blocking member 21 extends into the material cutting chamber 111 and separates the material cutting chamber 111 into two independent chambers, the first chamber 1111 and the second chamber 1112, in combination. Figure 5 and Figure 8 The first chamber 1111 is connected to the feeding hopper 20 of the freeze-dried pellet feeding device, and the second chamber 1112 is connected to the feeding hopper of the freeze-dried pellet dispensing device 100. For example... Figure 3 As shown, in the second position, the blocking member 21 moves out of the cutting chamber 111 so that the first chamber 1111 of the cutting chamber 111 can communicate with the feed bin.

[0062] The freeze-dried pellet quantitative feeding device provided in this embodiment stores freeze-dried pellets in its feeding hopper 20. Before the freeze-dried pellet feeding device is activated, the blocking member 21 is in the first position, and the first chamber 1111 and the second chamber 1112 are independent of each other. That is, the feeding hopper 20 of the freeze-dried pellet feeding device is not connected to the feeding hopper of the freeze-dried pellet dispensing device 100. After the freeze-dried pellet feeding device is activated, the freeze-dried pellets in the feeding hopper 20 can only enter the first chamber 1111 and be temporarily stored in the first chamber 1111. That is, the first chamber 1111 can temporarily store a certain amount of freeze-dried pellets. When the blocking member 21 switches from the first position to the second position, the first chamber 1111, the second chamber 1112, and the feeding hopper are connected. The freeze-dried pellets temporarily stored in the first chamber 1111 enter the feeding hopper of the freeze-dried pellet dispensing device 100 through the second chamber 1112, completing the quantitative feeding of the freeze-dried pellet dispensing device 100.

[0063] That is, each time the freeze-dried ball feeding equipment operates, it replenishes the freeze-dried ball dispensing equipment 100 with a fixed amount of freeze-dried balls that can be contained in the first chamber 1111, thereby achieving quantitative feeding of the freeze-dried ball dispensing equipment 100, accurately controlling the amount of freeze-dried balls fed at one time, preventing the freeze-dried ball dispensing equipment 100 from jamming, ensuring the continuity of freeze-dried ball dispensing production, and improving the efficiency of freeze-dried ball dispensing.

[0064] Optionally, see Figure 1 , Figure 2 and Figure 3The blocking mechanism 2 also includes a first driving member 22. A guide channel 114 communicating with the cutting chamber 111 is provided on the cutting bin 1. The blocking member 21 is movably inserted through the guide channel 114. The output end of the first driving member 22 is connected to the blocking member 21, used to drive the blocking member 21 to switch between a first position and a second position. In the first position, the blocking member 21 passes through the guide channel 114 and extends into the cutting chamber 111. The two sides of the blocking member 21 are the first chamber 1111 and the second chamber 1112, respectively. In the second position, the blocking member 21 retracts into the guide channel 114, and the first chamber 1111 communicates with the second chamber 1112. That is, the cutting chamber 111 as a whole can communicate with the feed bin of the freeze-dried pellet dispensing device 100, allowing the freeze-dried pellets to enter the feed bin. The guide channel 114 can restrict the movement direction of the blocking member 21, improving the movement stability of the blocking member 21. The linear movement of the blocking member 21 driven by the first driving member 22 is simple to control and easy to implement.

[0065] See Figure 1 The blocking member 21 is provided with a slot 211 at one end connected to the first driving member 22, and a snap-fit ​​connector 221 is provided at the output end of the first driving member 22. The snap-fit ​​connector 221 is snapped into the slot 211, which enables quick assembly and disassembly of the blocking member 21 and the first driving member 22. In other embodiments, bolts, screws, or other fasteners can also be used to fasten the connection between the output end of the first driving member 22 and the blocking member 21.

[0066] For example, the first driving member 22 is a cylinder, and the output rod of the cylinder is provided with the aforementioned snap-fit ​​connector 221. Of course, in other alternative embodiments, the first driving member 22 may also be a linear driving member such as an electric cylinder or a linear motor.

[0067] Optionally, see Figure 1 and combined Figure 6 The housing of the first drive component 22 is fixed to the feeding bin 20 of the freeze-dried ball feeding device via the first connecting seat 222. The first connecting seat 222 and the housing of the first drive component 22, as well as the first connecting seat 222 and the feeding bin 20, can be fastened with bolts or screws, ensuring reliable connection and easy disassembly.

[0068] In other alternative embodiments, the blocking member 21 can also be switched between a first position and a second position by rotation.

[0069] Optionally, see Figure 1 , Figure 2 , Figure 3 and Figure 4The material receiving bin 1 includes a material receiving bin body 11 and a metering element 12. The material receiving bin body 11 has a material receiving cavity 111. The metering element 12 is installed in the first chamber 1111 of the material receiving cavity 111. The metering element 12 has an inner cavity with a first inlet 121 and a first outlet 122. The first inlet 121 communicates with the feeding bin 20. When the blocking member 21 is in the first position, it blocks the first outlet 122, so that a certain amount of freeze-dried pellets are temporarily stored in the inner cavity of the metering element 12. The material receiving bin 1 is designed as a split structure, allowing the metering element 12 to be replaced separately to change the single feeding amount of freeze-dried pellets. Furthermore, the metering element 12 can be processed with a special material to make its inner wall smoother, preventing damage to the freeze-dried pellets and facilitating later cleaning, thus avoiding cross-contamination between different types of freeze-dried pellets. For example, the metering element 12 can be made of stainless steel.

[0070] See Figure 3 and Figure 4 The cross-sectional area of ​​the inner cavity of the metering component 12 gradually increases from the first inlet 121 to the first outlet 122. That is, the inner cavity of the metering component 12 is funnel-shaped, and its inner wall surface is inclined downward relative to the discharge end of the feeding hopper 20, which facilitates the automatic rolling of the freeze-dried balls from the feeding hopper 20 into the metering component 12, and ensures that the freeze-dried balls can be temporarily stored in the metering component 12 without flowing back into the feeding hopper 20. At the same time, when the blocking component 21 is switched to the second position, the freeze-dried balls in the metering component 12 can automatically roll down along the inclined wall surface into the second chamber 1112 and enter the feeding hopper of the freeze-dried ball dispensing device 100. In this embodiment, the blocking component 21 is a rectangular plate structure, which can effectively block the first outlet 122 in the first position.

[0071] It should be noted that the cross-sectional area here refers to the cross-sectional area of ​​the space where the inner cavity of the metering component 12 is located, rather than the cross-sectional area of ​​the metering component 12 itself.

[0072] See Figure 1 The metering element 12 is detachably installed in the first chamber 1111, and multiple metering elements 12 are provided, with different internal volumes. By replacing metering elements 12 with different volumes, the single feeding amount of freeze-dried pellets can be changed, thus expanding the applicability of the freeze-dried pellet feeding equipment.

[0073] In this embodiment, the material cutting cavity 111 is funnel-shaped, and the metering element 12 is also funnel-shaped, so that the metering element 12 can be stably embedded in the material cutting cavity 111. (Refer to...) Figure 3In the orientation of the metering element 12, the lower part is open, allowing the freeze-dried balls inside the metering element 12 to roll directly down the inclined inner wall of the material receiving cavity 111, making the flow of freeze-dried balls smoother. The external dimensions of multiple metering elements 12 can be designed to be the same, while the internal spaces of multiple metering elements 12 can be designed to be different. For example, by changing the thickness of the metering element 12, different metering elements 12 can have different volumes. This ensures that metering elements 12 with different volumes can be stably installed in the material receiving cavity 111, and when the blocking element 21 is in the first position, it can effectively block the first outlet 122 of the metering element 12.

[0074] Of course, in other embodiments, the lower part of the metering element 12 can also be designed to be closed, but the thickness of the lower side of the metering element 12 is thinner, and the volume of the metering element 12 is changed by changing the thickness of the upper side of the metering element 12. It can be understood that the upper side and the lower side are relative to the first chamber 1111 of the metering element 12 installed in the cutting chamber 111, that is, with the metering element 12 after normal installation as a reference.

[0075] Optionally, see Figure 2 and Figure 3 The material receiving bin 1 is provided with a discharge port 112 at the bottom of the second chamber 1112, and the discharge port 112 is not higher than the first outlet 122, so that after the blocking member 21 is switched to the second position, the freeze-dried balls in the first chamber 1111 can smoothly roll from the first outlet 122 to the discharge port 112, thereby improving the ball dropping efficiency.

[0076] Furthermore, combined Figure 6 and Figure 8 The discharge port 112 is connected to the feed hopper of the freeze-dried ball dispensing device 100 via the conveying pipe 4. When the blocking member 21 is switched to the second position, the freeze-dried balls in the cutting chamber 111 automatically converge towards the discharge port 112 under their own gravity and roll into the conveying pipe 4. The freeze-dried balls enter the feed hopper of the freeze-dried ball dispensing device 100 along the conveying pipe 4. The conveying pipe 4 can guide the freeze-dried balls into the feed hopper and ensure that the freeze-dried balls are in a closed environment during the feeding process to prevent contamination of the freeze-dried balls.

[0077] like Figure 2 and Figure 3 As shown, a pipe connector 116 is installed at the discharge port 112 of the material hopper 1, and the material conveying pipe 4 is inserted into the pipe connector 116. For example, the outer peripheral surface of the pipe connector 116 is provided with a backstop structure. After the pipe connector 116 is inserted into the material conveying pipe 4, it can be tightly fitted with the inner wall of the material conveying pipe 4 through the backstop structure, ensuring that the material conveying pipe 4 and the pipe connector 116 are reliably connected.

[0078] Optionally, see Figure 1 , Figure 2 and Figure 3The material receiving hopper 1 has an observation port 113 on the side of the second chamber 1112 opposite to the first chamber 1111. An observation window 5 is provided at the observation port 113 to observe the condition inside the material receiving chamber 111. Operators can observe the state of the freeze-dried pellets inside the material receiving chamber 111 through the observation window 5, enabling them to promptly detect malfunctions and take appropriate measures. For example, in the event of material blockage, a timely shutdown operation can be performed. In this embodiment, the observation window 5 is made of transparent material to ensure visibility.

[0079] For example, the observation window 5 is made of transparent acrylic material, which has good visibility, strong structural strength, and long service life.

[0080] Furthermore, the observation window 5 is detachably installed on the material cutting chamber 1, facilitating cleaning of the material cutting chamber 111 after removing the observation window 5. In this embodiment, see [reference needed]. Figure 1 The observation window 5 is equipped with a magnetic component 511 (such as a magnet). The observation window 5 is magnetically fixed to the material collection bin 1 by the magnetic component 511. The disassembly and assembly are simple and can be quickly disassembled and assembled, improving the efficiency of cleaning and maintenance.

[0081] See Figure 1 and Figure 3 The observation window 5 includes a window frame 51 and a sealing plate 52. The window frame 51 is hollow in the middle. The sealing plate 52 is located in the middle of the window frame 51 and protrudes towards the cutting chamber 1. The magnetic suction component 511 is located on the window frame 51. After the observation window 5 is magnetically fixed to the cutting chamber 1, the sealing plate 52 is embedded in the observation opening 113, which can effectively block the observation opening 113 and ensure the sealing of the cutting chamber 111. Furthermore, the above structural design ensures that the position of the observation window 5 corresponding to the observation opening 113 is not too thick, thus ensuring the transparency effect.

[0082] For example, the window frame 51 is rectangular, with a magnetic suction member 511 at each of its four corners. Correspondingly, the cutting bin 1 has four grooves on the side facing the observation window 5. The four magnetic suction members 511 can be inserted into the four grooves one by one, increasing the magnetic suction area of ​​the magnetic suction members 511 and improving the installation stability of the observation window 5.

[0083] In other embodiments, the observation window 5 can also be fixed to the cutting bin 1 by screws or the like, which also allows for the removal of the observation window 5.

[0084] Optionally, see Figure 5 , Figure 6 and Figure 7The freeze-dried pellet quantitative feeding device also includes an air blowing mechanism 3. The air outlet of the air blowing mechanism 3 is connected to the material cutting chamber 111, which is used to blow the freeze-dried pellets in the material cutting chamber 111 into the feeding bin. When the first driving member 22 drives the blocking member 21 to switch to the second position, it controls the air blowing mechanism 3 to act, so as to assist in sending the freeze-dried pellets in the quantitative member 12 in the material cutting chamber 111 into the conveying pipe 4, so that the freeze-dried pellets can enter the feeding bin of the freeze-dried pellet dispensing equipment 100 more smoothly, and further improve the feeding efficiency.

[0085] Of course, it is understandable that the blowing mechanism 3 could also be controlled to operate simultaneously with the first driving component 22 driving the blocking component 21 to switch to the second position, in order to assist in feeding the freeze-dried balls in the metering component 12 in the cutting chamber 111 into the conveying pipe 4. This application does not restrict the order in which the first driving component 22 drives the blocking component 21 to switch to the second position and the blowing mechanism 3 is controlled to operate, as long as it can be ensured that the freeze-dried balls in the metering component 12 in the cutting chamber 111 are fed into the conveying pipe 4 and do not flow back to the feeding bin 20.

[0086] See Figure 2 , Figure 3 and Figure 5 The material receiving hopper 1 is equipped with an air inlet channel 115 that connects to the material receiving chamber 111. The air inlet channel 115 has a second inlet and a second outlet. The second inlet is connected to the air outlet of the blowing mechanism 3, and the second outlet is located at the end of the material receiving chamber 111 near the feeding hopper 20 of the freeze-dried pellet feeding device. After the airflow generated by the blowing mechanism 3 enters the air inlet channel 115, it can be blown towards the freeze-dried pellets in the material receiving chamber 111 through the second outlet, causing the freeze-dried pellets to move towards the discharge port 112 under the propulsion of the airflow. Since the second outlet is at the end of the material receiving chamber 111 near the feeding hopper 20, it can further prevent the freeze-dried pellets from flowing back into the feeding hopper 20. The method of driving the freeze-dried pellets by blowing air can prevent foreign objects from directly contacting the freeze-dried pellets and prevent contamination of the freeze-dried pellets. At the same time, the airflow driving method is relatively gentle, which can prevent the freeze-dried pellets from breaking or shedding powder, and ensure the quality of the freeze-dried pellets.

[0087] For example, the blowing mechanism 3 is exemplarily an air pump or the like, as long as it can generate a stable airflow.

[0088] See Figure 3 The air intake channel 115 includes a first channel 1151 and a second channel 1152 that are connected to each other. The width of the second channel 1152 is smaller than the width of the first channel 1151. This arrangement allows the airflow reaching the second outlet to have a certain speed, which is sufficient to drive the freeze-dried balls to converge smoothly at the discharge port 112.

[0089] See Figure 3 and Figure 4The metering component 12 of the cutting bin 1 is provided with an air inlet 123, which is directly opposite to the second outlet of the air inlet channel 115, ensuring that the air blowing mechanism 3 can smoothly blow the airflow into the metering component 12.

[0090] Example 2

[0091] In existing technologies, on automated freeze-dried pellet packaging production lines, freeze-dried pellets are typically fed using a vibrating disc to dispose of them. This method can easily damage the freeze-dried pellets and affect their quality after packaging.

[0092] To solve the above problems, such as Figures 6 to 8 As shown, this embodiment provides a freeze-dried pellet feeding device that can prevent freeze-dried pellets from being damaged and ensure the quality of freeze-dried pellets.

[0093] The freeze-dried pellet feeding device includes a fixed frame 10, a feeding hopper 20, a second driving component 30, and a freeze-dried pellet quantitative feeding device as described in Embodiment 1. The feeding hopper 20 is rotatably mounted on the fixed frame 10. The output end of the second driving component 30 is movably connected to the feeding hopper 20, and is used to drive the feeding hopper 20 to tilt relative to the fixed frame 10 at a preset angle. The freeze-dried pellet quantitative feeding device is located at the discharge end of the feeding hopper 20. (See reference...) Figure 5 The feeding hopper 20 has a receiving cavity 2021 for holding freeze-dried pellets. The receiving cavity 2021 has a third inlet and a third outlet 2023. The third inlet is the feed port 2022 of the feeding hopper 20, and the third outlet 2023 is connected to the first chamber 1111 of the cutting chamber 111 of the cutting hopper 1. In this embodiment, the end where the third outlet 2023 is located is the discharge end of the feeding hopper 20.

[0094] When it is necessary to feed material into the freeze-dried pellet dispensing device 100, the second drive component 30 is controlled to drive the feeding hopper 20 to rotate and tilt relative to the fixed frame 10 at a preset angle (e.g., Figure 7 As shown, the receiving cavity 2021 of the feeding hopper 20 is tilted relative to the horizontal plane. At this time, the freeze-dried balls in the receiving cavity 2021 can roll into the first chamber 1111 under their own gravity. This freeze-dried ball feeding device only needs to control the feeding hopper 20 to tilt at a certain angle through the second drive component 30 to make the freeze-dried balls automatically enter the first chamber 1111 of the cutting cavity 111, realize the automatic dropping of freeze-dried balls, avoid the freeze-dried balls from being broken due to vibration, prevent the freeze-dried balls from being damaged, and ensure the quality of the freeze-dried balls after packaging.

[0095] See Figure 6 and Figure 7The feeding hopper 20 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 feeding hopper 20 is rotatably connected to the fixed frame 10. The second driving member 30 is used to drive the feeding hopper 20 to swing up and down relative to the fixed frame 10, so that the second end rises or falls relative to the first end. Specifically, when the output end of the second driving member 30 rises, it can apply an upward force to the feeding hopper 20. Since the first end of the feeding hopper 20 is rotatably connected to the fixed frame 10, the second end, which is the free end in the feeding hopper 20, can rise relative to the first end, causing the feeding hopper 20 to tilt relative to the fixed frame 10. This allows the freeze-dried balls in the feeding hopper 20 to roll into the cutting chamber 111 under their own gravity. The method of adjusting the tilt angle of the feeding hopper 20 by lifting and lowering is simple in structure, 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.

[0096] For example, the second driving component 30 can be a cylinder, with the cylinder's output rod movably connected to the feeding bin 20. By lifting the second end of the feeding bin 20, the feeding bin 20 is tilted at a certain angle. In other embodiments, the second driving component 30 can also be a linear driving component such as an electric cylinder, a linear motor, or a lead screw and nut mechanism.

[0097] 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 second drive component 30 can be raised to a higher height, causing the feeding bin 20 to tilt at a larger angle; if the amount of freeze-dried pellets replenished is small, the second drive component 30 can be raised to a lower height, causing the feeding bin 20 to tilt at a smaller angle.

[0098] In this embodiment, refer to Figure 7 In terms of orientation, the left end of the feeding hopper 20 is the first end, and the right end of the feeding hopper 20 is the second end.

[0099] Optionally, see Figure 6 and Figure 7 The output end of the second driving component 30 is provided with a rotatable rolling element 301, which can roll and engage with the outer peripheral surface of the feeding bin 20. During the process of the second driving component 30 driving the second end of the feeding bin 20 to rise and fall, the rolling element 301 always rolls and engages with the outer peripheral surface of the feeding bin 20 in the tilt direction of the feeding bin 20, which can reduce the driving resistance of the second driving component 30 and improve the driving efficiency.

[0100] For example, the rolling element 301 is a roller, and the output end of the second driving member 30 is provided with a connecting block 302. A connecting shaft is rotatably provided on the connecting block 302, and a roller is provided at each end of the connecting shaft. The two rollers simultaneously roll and cooperate with the feeding bin 20, which can improve the cooperation stability between the second driving member 30 and the feeding bin 20.

[0101] In other embodiments, the output end of the second driving member 30 can also be slidably connected to the feeding bin 20. During the lifting and lowering process of the second driving member 30, the output end of the second driving member 30 adaptively slides relative to the feeding bin 20, thereby preventing the feeding bin 20 from interfering with the lifting and lowering of the second driving member 30. Specifically, a slider can be provided at the output end of the second driving member 30, and correspondingly, a groove extending along the inclined direction of the feeding bin 20 is provided on the feeding bin 20, with the slider slidingly engaging with the groove.

[0102] See Figure 6 and Figure 7 The freeze-dried pellet feeding device also includes an elastic element 40. One end of the elastic element 40 is connected to the fixed frame 10, and the other end is connected to the feeding bin 20. The rolling element 301 can always be in contact with the outer peripheral surface of the feeding bin 20 under the elastic force of the elastic element 40. That is, the elastic element 40 is always in an energy storage state, which can apply a pulling force to the feeding bin 20, so that the outer peripheral surface of the feeding bin 20 is always in contact with the rolling element 301. This ensures that the rolling element 301 can always roll and cooperate with the outer peripheral surface of the feeding bin 20 during the lifting and lowering process of the second drive element 30, thereby improving the stability of the feeding bin 20 during the tilting process. At the same time, the setting of the elastic element 40 can limit the maximum rising height of the second end of the feeding bin 20, preventing the feeding bin 20 from tilting excessively and causing it to overturn.

[0103] In addition, the elastic element 40 also has a resetting function for the feeding bin 20, enabling the feeding bin 20 to move downwards and reset to a horizontal position. Specifically, when the second drive element 30 descends, the feeding bin 20 can descend accordingly under the pulling force of the elastic element 40, causing the feeding bin 20 to automatically reset.

[0104] For example, the elastic element 40 is a tension spring. The fixing frame 10 is provided with a first connecting plate 1013, and the feeding bin 20 is provided with a second connecting plate 2013. Both ends of the tension spring are provided with hooks, and both the first connecting plate 1013 and the second connecting plate 2013 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 fixing frame 10 and the feeding bin 20, and to facilitate disassembly.

[0105] Of course, in other embodiments, the elastic element 40 may not be provided. For example, the rolling element 301 at the output end of the second drive element 30 is rolled and connected to the feeding bin 20, or the output end of the second drive element 30 is slidably connected to the feeding bin 20. When the output end of the second drive element 30 rises and falls, it drives the feeding bin 20 to move together, so that the feeding bin 20 can tilt at a preset angle and also return to its original position.

[0106] See Figure 6A guide cylinder 1021 is provided on the fixed frame 10, and a first guide rod 2012 is provided on the feeding bin 20. The first guide rod 2012 is inserted into the guide cylinder 1021 and slides in cooperation with the guide cylinder 1021. During the process of the second drive component 30 driving the second end of the feeding bin 20 to rise and fall, the first guide rod 2012 always slides in cooperation with the guide cylinder 1021, which can prevent the feeding bin 20 from tilting during the rising and falling process and further improve the stability of the feeding bin 20 during the tilting process.

[0107] Optionally, see Figure 6 , Figure 7 and Figure 8 The mounting frame 10 includes a base 101 and a support frame 102 mounted on the base 101. The second drive component 30 is mounted on the base 101, and the feeding hopper 20 is rotatably mounted on the support frame 102. The base 101 can be fixed to the base of the freeze-dried pellet packaging production line to mount the freeze-dried pellet feeding equipment above the freeze-dried pellet dispensing equipment 100. The support frame 102 can mount the feeding hopper 20 above the second drive component 30, providing lifting space for the second drive component 30 to adjust the tilt angle of the feeding hopper 20.

[0108] Specifically, see Figure 6 The base 101 is a rectangular frame structure. The support frame 102 includes a support column and a support frame. A support column is set at each of the four corners of the support frame. All four support columns are fixedly connected to the base 101. The second driving component 30 is located in the space formed between the support frame and the base 101.

[0109] See Figure 6 and Figure 7 The support frame 102 of the fixed frame 10 is provided with a second connecting seat 1022, and a connecting ear is provided on the second connecting seat 1022. The feeding bin 20 is provided with a rotating groove (not shown in the figure). The connecting ear is rotatably installed in the rotating groove through a rotating shaft 205 to realize the rotatable connection between the feeding bin 20 and the support frame 102.

[0110] Optionally, see Figure 6 and Figure 7 The fixed frame 10 is equipped with an adjustable-angle mounting base 1011. The housing of the second drive component 30 is fixed to the mounting base 1011. The maximum tilt angle of the feeding hopper 20 can be adjusted by adjusting the tilt angle of the mounting base 1011. When the tilt angle of the mounting base 1011 relative to the fixed frame 10 changes, the lifting direction of the second drive component 30 changes accordingly, thereby changing the maximum vertical lifting height of the output end of the second drive component 30 and adjusting the maximum tilt angle of the feeding hopper 20. Before feeding freeze-dried pellets, the tilt angle of the mounting base 1011 relative to the fixed frame 10 can be adjusted according to the feeding requirements of the freeze-dried pellets to ensure that the maximum tilt angle of the feeding hopper 20 meets the requirements.

[0111] Continue reading Figure 6 and Figure 7 The base 101 of the fixing frame 10 is provided with a first fixing seat 1012, and the mounting seat 1011 is rotatably mounted on the first fixing seat 1012. The tilt angle can be adjusted by rotating the mounting seat 1011. Specifically, a locking structure (such as a locking bolt or locking pin) can be provided on the first fixing seat 1012. When it is necessary to adjust the tilt angle of the installation, the locking structure is released from the mounting seat 1011, and then the mounting seat 1011 is rotated to adjust the tilt angle. After the mounting seat 1011 is adjusted to the right tilt angle, the locking structure is used to lock the mounting seat 1011 to the first fixing seat 1012 to prevent the mounting seat 1011 from continuing to rotate and to ensure that the second driving component 30 is securely fixed.

[0112] Optionally, see Figure 5 and Figure 6 The freeze-dried pellet feeding equipment also includes a sealing component 50 located at the feed inlet 2022. The sealing component 50 is used to seal or open the feed inlet 2022. When feeding freeze-dried pellets, the feed inlet 2022 is opened by the sealing component 50, and after a certain amount of freeze-dried pellets are loaded into the receiving cavity 2021, the feed inlet 2022 is sealed by the sealing component 50. This prevents external dust and debris from entering the receiving cavity 2021 and ensures that the freeze-dried pellets are not contaminated.

[0113] See Figure 5 and Figure 6 The feeding hopper 20 is provided with a feeding hopper 203 at the feeding inlet 2022. The feeding hopper 203 has a guide ramp for guiding the freeze-dried balls to the feeding inlet 2022. The feeding hopper 203 expands the feeding space, which is more conducive to adding freeze-dried balls into the receiving cavity 2021, improving the feeding efficiency of freeze-dried balls, and preventing freeze-dried balls from falling to the outside. By providing a guide ramp on the feeding hopper 203, it is more conducive to the freeze-dried balls rolling from the feeding inlet 2022 into the receiving cavity 2021, further improving the feeding efficiency of freeze-dried balls. Exemplarily, the feeding hopper 203 is shaped like a shovel. In other embodiments, the feeding hopper 203 may also be shaped like a funnel. Specifically, see [reference needed]. Figure 5 The guide slope is set downward along the direction close to the feed inlet 2022.

[0114] Optionally, the sealing assembly 50 includes a third drive component 501 and a sealing component 502. The sealing component 502 is movably disposed in the feeding hopper 20 and has a blocking position for blocking the feed inlet 2022 and an opening position for opening the feed inlet 2022. The output end of the third drive component 501 is connected to the sealing component 502 and is used to drive the sealing component 502 to switch between the blocking position and the opening position. When it is necessary to replenish material into the receiving cavity 2021, the third drive component 501 controls the sealing component 502 to move from the blocking position to the opening position to open the feed inlet 2022. After replenishment is completed, the third drive component 501 controls the sealing component 502 to move from the opening position to the blocking position to block the feed inlet 2022, ensuring the sealing of the receiving cavity 2021 and preventing contamination of the freeze-dried bulbs. The third drive component 501 enables electric control of the opening and closing of the feed inlet 2022, improving the degree of automation.

[0115] In this embodiment, the sealing component 502 is slidably disposed on the feeding bin 20, and the third driving component 501 is a linear driving component that can drive the sealing component 502 to slide and switch between the sealing position and the open position. Specifically, the feeding bin 20 is provided with a guide rail, and the sealing component 502 is provided with a slider. The slider is slidably connected to the guide rail to guide the sliding of the sealing component 502 and improve the movement accuracy of the sealing component 502.

[0116] See Figure 6 A second fixed base 2014 is provided on the feeding hopper 20, and the housing of the third driving member 501 is fixed on the second fixed base 2014. A first protrusion 5021 protrudes from the top of the sealing member 502, and the output end of the third driving member 501 is fixedly connected to the first protrusion 5021 to drive the sealing member 502 to slide relative to the feeding hopper 20. Furthermore, the first driving member 22 is fixed on the second fixed base 2014 through a first connecting seat 222, providing sufficient movement space for the output end of the first driving member 22.

[0117] For example, the third driving member 501 can be a cylinder, and the output rod of the cylinder is fixedly connected to the sealing member 502. In other embodiments, the third driving member 501 can also be a linear driving member such as an electric cylinder.

[0118] See Figure 6 The feeding hopper 20 is provided with a third fixed seat 2015, and the third fixed seat 2015 is provided with a second guide rod 2016 extending along the sliding direction of the sealing member 502. The sealing member 502 is provided with a second protrusion 5022 on its side, and the second protrusion 5022 is provided with a guide hole. The second guide rod 2016 is movably inserted through the guide hole. When the third driving member 501 drives the sealing member 502 to slide, the second guide rod 2016 slides with the guide hole, which can further improve the movement stability of the sealing member 502.

[0119] In other alternative embodiments, the sealing element 502 may also be rotatably disposed on the feeding hopper 20, and the feeding port 2022 may be blocked or opened by driving the sealing element 502 to rotate.

[0120] Optionally, see Figure 5 The feeding hopper 20 includes a feeding hopper body 201 and a feeding body 202. The feeding hopper body 201 has an installation cavity 2011, and the feeding body 202 is fitted into the installation cavity 2011. The feeding body 202 has a hollow inner cavity, which is a receiving cavity 2021, and the cross-sectional area of ​​the receiving cavity 2021 gradually decreases along the direction approaching the third outlet 2023. That is, the receiving cavity 2021 is funnel-shaped. When the feeding hopper 20 is tilted, the freeze-dried balls in the receiving cavity 2021 are more likely to automatically converge into the cutting cavity 111 under their own gravity, improving the ball dropping efficiency. Furthermore, the above design of the receiving cavity 2021 ensures that the freeze-dried balls in the receiving cavity 2021 only flow into the cutting cavity 111 when the feeding hopper 20 is tilted; when the feeding hopper 20 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 2021 is located, not the cross-sectional area of ​​the feeding body 202.

[0121] Because freeze-dried pellets are relatively brittle and easily broken, the feeding hopper 20 is designed as a separate structure. The feeding body 202 can be processed separately using a special material, resulting in a smoother inner wall to prevent breakage of the freeze-dried pellets and facilitate subsequent cleaning of the receiving cavity 2021, avoiding cross-contamination between different types of freeze-dried pellets. Furthermore, different materials can be used to manufacture the feeding hopper body 201 and the feeding body 202, reducing the processing cost and difficulty of the feeding hopper 20. For example, the feeding body 202 can be made of stainless steel, ensuring a smooth inner wall.

[0122] In addition, the split structure design of the feeding hopper 20 allows for the replacement of feeding bodies 202 with appropriate volumes according to actual needs. That is, multiple feeding bodies 202 with different volumes can be made, and the feeding body 202 with the required volume can be replaced as needed, without having to replace the entire feeding hopper 20. This is convenient, quick, and more cost-effective.

[0123] Optionally, see Figure 5 , Figure 6 and Figure 7The feeding hopper 20 also includes a cover 204, which is fixedly connected to the opening of the mounting cavity 2011 of the feeding hopper body 201. The cover 204 has an opening at its top, which serves as the feed inlet 2022 of the feeding hopper 20. A feed hopper 203 is fixed to the opening of the cover 204. When adding material to the receiving cavity 2021, simply pour the freeze-dried pellets into the feed hopper 203, and the freeze-dried pellets will automatically roll from the feed inlet 2022 into the receiving cavity 2021. The cover 204 ensures that the receiving cavity 2021 can only communicate with the outside through the opening of the cover 204, facilitating the sealing assembly 50 to seal the feed inlet 2022, ensuring the sealing of the receiving cavity 2021, and preventing contamination of the freeze-dried pellets.

[0124] In this embodiment, the sealing member 502 of the sealing assembly 50 has an arc-shaped convex surface at one end facing the feed inlet 2022, see reference. Figure 5 The opening of the cover 204 is provided with a concave surface 2041. When the sealing member 502 is in the sealing position, the arc-shaped convex surface of the sealing member 502 can fit with the concave surface 2041 on the cover 204, ensuring that the feed inlet 2022 is tightly sealed.

[0125] Optionally, see Figure 5 , Figure 6 , Figure 7 and Figure 8 The freeze-dried pellet feeding device includes a detection element 60 installed in the feeding hopper 20. The detection element 60 is used to detect the remaining amount of freeze-dried pellets in the receiving cavity 2021. The detection element 60 allows operators to monitor the remaining amount of freeze-dried pellets in the receiving cavity 2021, facilitating the determination of the quantity of freeze-dried pellets to be added to the receiving cavity 2021 based on the remaining amount, thereby accurately controlling the feeding amount of freeze-dried pellets. Freeze-dried pellets can be added manually to the feeding inlet 2022, or the machine can automatically add freeze-dried pellets to the feeding inlet 2022.

[0126] Furthermore, when the detection element 60 detects that the remaining amount of freeze-dried balls in the receiving cavity 2021 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 2021 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.

[0127] In this embodiment, the detection element 60 includes an optical fiber detection element, that is, the remaining amount of freeze-dried bulbs in the receiving cavity 2021 is determined by optical fiber detection, which has high detection efficiency and accuracy. Specifically, see [link to relevant documentation]. Figure 5 The detection element 60 is installed on the cover 204 of the feeding hopper 20, and the detection end of the detection element 60 is located inside the receiving cavity 2021. When the remaining amount of freeze-dried balls in the receiving cavity 2021 is insufficient to submerge the feed hopper 2021, the detection element 60 is installed on the cover 204 of the feeding hopper 2020. Figure 5When the height of the dotted line in the image is reached, the detector 60 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 2021.

[0128] 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.

[0129] In other embodiments, the detection element 60 may also be an infrared sensor or the like, which detects the remaining amount of freeze-dried bulbs in the receiving cavity 2021.

[0130] See Figure 8 Multiple feeding hoppers 20 are installed on the fixed frame 10. Each feeding hopper 20 is equipped with a freeze-dried bulb quantitative feeding device at its discharge end. These multiple freeze-dried bulb quantitative feeding devices are connected one-to-one with the feeding hoppers of multiple freeze-dried bulb dispensing devices 100 via conveying pipes 4, thereby feeding multiple freeze-dried bulb dispensing devices 100 and improving feeding efficiency. A freeze-dried bulb dispensing device 200 is also connected below each freeze-dried bulb dispensing device 100. The dispensing device 200 has a discharge nozzle for insertion into a container 300 storing freeze-dried bulbs. The receiving cavities 2021 of the multiple feeding hoppers 20 can contain the same type of freeze-dried bulbs, allowing the multiple freeze-dried bulb dispensing devices 200 to simultaneously dispense freeze-dried bulbs into multiple containers 300, improving the freeze-dried bulb dispensing efficiency. Different types of freeze-dried balls can also be added to the receiving chambers 2021 of multiple feeding hoppers 20, so that multiple freeze-dried ball dispensing devices 200 can output different types of freeze-dried balls respectively. When loading balls into different types of reaction plates, one of the freeze-dried ball dispensing devices 200 can be selected to load balls into the corresponding type of reaction plate, which has a wider range of applications.

[0131] In this embodiment, the freeze-dried pellet feeding device includes a control module. The detection component 60, the first drive component 22, the second drive component 30, the third drive component 501, and the air blowing mechanism 3 are all communicatively connected to the control module. The control module can control the opening and closing of the first drive component 22, the second drive component 30, the third drive component 501, and the air blowing mechanism 3 according to the information detected by the detection component 60, so as to realize automated control of freeze-dried pellet feeding.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention.
