Description

Technical Field

[0001] This utility model relates to the field of automated in vitro diagnostic equipment, specifically to a reaction cup feeding device and a testing and analysis instrument. Background Technology

[0002] Chemiluminescence immunoassay analyzers are medical testing instruments that perform immunological analysis on patients' serum. In fully automated chemiluminescence immunoassay analyzers, reaction cups are typically transported using a sprocket and chain system. However, due to the irregular discharge of reaction cups from the hopper outlet and the potential for cup inversion during sprocket and chain transport, jamming can easily occur in the next transport stage, interrupting the testing process and severely impacting efficiency. To address these issues, a novel feeding device is needed. Utility Model Content

[0003] Therefore, the technical problem this invention aims to solve is how to address the issue in existing chemiluminescence immunoassay analyzers where the reaction cups are easily inverted or jammed during transport, leading to interruptions in the detection process and severely impacting detection efficiency. To this end, this invention provides a reaction cup loading device and a testing analyzer.

[0004] In a first aspect, this utility model provides a reaction cup feeding device, comprising:

[0009] Optionally, the cup-pulling structure further includes:

[0010] The geared disc is coaxially and fixedly connected to the second rotating shaft;

[0011] A rocker arm is rotatably mounted on the conveying structure via a pin. The first end of the rocker arm has a protrusion that engages with the teeth of the gear disc, and the second end is connected to the paddle so that the end of the paddle remains close to the slide.

[0012] A reset spring, one end of which is connected to the conveying structure and the other end of which is connected to the rocker arm with the connection point located between the pin and the protrusion, the reset spring having a pre-tension amount;

[0013] The surface of the paddle facing the slide is a convex arc surface.

[0014] Optionally, a limiting plate is provided on one side of the swing arm, and a mounting plate parallel to the end face of the limiting plate is provided on the opposite side. The protrusion is mounted on the mounting plate by a pin, and the wheel tooth is located between the limiting plate and the mounting plate.

[0015] Optionally, the rocker arm is provided with an extension parallel to the second rotation axis, and the other end of the return spring is connected to the extension. The return spring is located between the gear plate and the conveying structure.

[0016] Optionally, the slide is positioned close to the conveying path of the conveyor belt, and the slide has an upward-facing receiving port.

[0017] Optionally, the conveyor belt is connected to the first and second rotating shafts via a gear and rack structure. The feeding block includes a carrier plate parallel to the conveyor belt and a side plate inclined relative to the direction of movement of the conveyor belt on the carrier plate. Optionally, the discharge port of the hopper is provided with a first baffle and a second baffle extending along the direction of movement of the conveyor belt. The first and second baffles are connected to the conveying structure and form a conveying channel. The conveyor belt is located between the first and second baffles. The first baffle blocks between the side plate and the receiving port. The reaction cup located on the side plate has a tendency to slide towards the first baffle.

[0018] Optionally, the first driving structure includes: a first driving member disposed at the bottom of the conveying structure, wherein the output end of the first driving member is connected to the first rotating shaft via a pulley transmission structure.

[0019] Secondly, this utility model provides a testing and analysis instrument, including the reaction cup feeding device described above.

[0020] The technical solution of this utility model has the following advantages:

[0021] 1. The reaction cup feeding device provided by this utility model includes: a hopper; a conveying structure including a conveyor belt partially extending into the hopper, with a plurality of feeding blocks arranged on the conveyor belt; a first driving structure connected to the conveyor belt for driving the conveyor belt to circulate along the height direction; and a cup-adjusting structure including a lever, the end of which swings back and forth in the extension direction of the slide under the drive of the first driving structure to adjust the reaction cups on the slide.

[0022] In this invention, the conveying structure uses a conveyor belt and multiple feeding blocks to remove reaction cups from the hopper. Specifically, a first drive structure drives the conveyor belt to circulate vertically, and multiple feeding blocks circulate into the hopper, carrying the reaction cups. The reaction cups are then transferred to a slide rail through a receiving port. The reaction cups slide within the slide rail and proceed to the next stage. A cup-adjusting mechanism uses a lever to correct the movement of the cups along the slide rail. Specifically, the first drive structure drives the end of the lever to swing back and forth along the extension direction of the slide rail. The distance between the lever end and the slide rail can be set according to the difference in the length of the reaction cup extending beyond the slide rail in the correct and incorrect postures. This allows reaction cups in the correct posture to slide smoothly downstream along the slide rail, while reaction cups in the incorrect posture are blocked and agitated by the lever. Under this force, the reaction cups readjust to the correct posture before entering the slide rail, thus completing the adjustment of the cup posture. This avoids the occurrence of cup inversion and conveying jams during the conveying process due to irregular feeding of reaction cups, ensuring the continuity of the testing process and improving testing efficiency. In addition, the conveyor belt of the conveying structure and the paddle of the cup-pulling mechanism share the first drive structure for power, which reduces the number of drive structures, reduces the size of the equipment, reduces energy consumption, and saves costs.

[0023] 2. The reaction cup feeding device provided by this utility model includes a first rotating shaft and a second rotating shaft in the conveying structure. The first rotating shaft is connected to the first driving structure in a transmission manner, and the conveyor belt is wound around the first rotating shaft and the second rotating shaft.

[0024] In this invention, the movement path of the conveyor belt is defined by the rotation of the first rotating shaft and the second rotating shaft. The first driving structure drives the first rotating shaft to rotate and drive the conveyor belt to move, so that the conveyor belt can move clockwise or counterclockwise around the relative outer edges of the first rotating shaft and the second rotating shaft. The feeding block located on the conveyor belt can also move clockwise or counterclockwise, thereby realizing the cyclical entry into the hopper and transfer of the reaction cup.

[0025] 3. The reaction cup feeding device provided by this utility model further includes: a toothed disc, coaxially and fixedly connected to the second rotating shaft; a rocker arm, rotatably mounted on the conveying structure via a pin, wherein the first end of the rocker arm has a protrusion that contacts and engages with the teeth of the toothed disc, and the second end is connected to the paddle so that the end of the paddle remains close to the slide rail; a return spring, one end of which is connected to the conveying structure, and the other end of which is connected to the rocker arm with the connection point located between the pin and the protrusion, wherein the return spring has a pre-tension amount; and the surface of the paddle facing the slide rail is a convex arc surface.

[0026] In this invention, the gear disc and the second rotating shaft are coaxially fixedly connected. Since the second rotating shaft is rotatably mounted on the conveying structure, the first driving structure can drive the second rotating shaft to rotate through the first rotating shaft and the conveyor belt, so that the gear disc and the second output shaft rotate synchronously. As the outer edge of the gear disc makes a circular motion, the protrusion of the rocker arm successively interacts with the tip of the gear tooth and the groove between two adjacent gear teeth. Since the radial dimension of the gear tooth tip is greater than the radial dimension of the bottom of the groove, the protrusion will reciprocate towards the center of the gear disc and away from the center of the gear disc. The first end of the rocker arm swings synchronously with the protrusion. When the protrusion slides from the groove to the tip of the gear tooth, the return spring gains elastic potential energy. When the protrusion leaves the tip of the gear tooth, the return spring pulls the first end of the rocker arm towards the center of the gear disc through elastic force, so that the protrusion gradually slides into the groove, thereby ensuring that the first end of the rocker arm can reciprocate.

[0027] Because the swing arm is rotatably mounted on the conveying structure via a pin, the second end of the swing arm can swing in the opposite direction to the first end with the pin as the swing center. This causes the paddle connected to the second end to swing synchronously, so that the end of the paddle swings back and forth in the direction of approaching or moving away from the slide. Specifically, when the protrusion slides from the groove to the tip of the tooth, the end of the paddle moves away from the slide. When the protrusion leaves the tip of the tooth, the end of the paddle moves towards the slide. After the protrusion is disengaged from the resistance of the tip of the tooth, it can quickly enter the groove under the elastic force of the return spring. Due to the radial dimension difference between the tip of the tooth and the bottom of the groove, the end of the paddle can move quickly towards the slide. It uses a short burst of force to impact the reaction cup with the wrong posture. After being impacted, the reaction cup with the wrong posture will quickly adjust its posture to the correct posture, thus improving the effect of correcting the posture of the reaction cup.

[0028] It is evident that the combination of the above structures not only enables the toothed disc and conveyor belt to share the first drive structure, but also improves the correction effect on the reaction cup, further solving the problem of reaction cup conveying jam.

[0029] 4. The reaction cup feeding device provided by this utility model has a limiting plate on one side of the swing rod, and an installation plate parallel to the end face of the limiting plate on the opposite side. The protrusion is installed on the installation plate by a pin, and the gear teeth are located between the limiting plate and the installation plate.

[0030] The limiting plate and mounting plate can limit the relative position of the rocker arm and the gear to ensure that the protrusion and the gear teeth always maintain a mating relationship and prevent the paddle from failing.

[0031] 5. The reaction cup feeding device provided by this utility model has an extension on the swing arm parallel to the second rotating shaft, and the other end of the return spring is connected to the extension. The return spring is located between the toothed disc and the conveying structure. This arrangement makes the structure compact.

[0032] 6. The reaction cup feeding device provided by this utility model has a slide rail located close to the conveyor belt's conveying path, and the slide rail has an upward-facing receiving port. The reaction cups transferred by the conveyor belt can fall directly into the slide rail through the receiving port, and then be aligned using a lever.

[0033] 7. The reaction cup feeding device provided by this utility model, wherein the conveyor belt is connected to the first rotating shaft and the second rotating shaft through a gear and rack structure, and the feeding block includes a carrier plate connected parallel to the conveyor belt, and a side plate disposed on the carrier plate at an inclination relative to the direction of movement of the conveyor belt, the side plate being used to transfer the reaction cup.

[0034] In this invention, sprockets can be coaxially fixed on the first and second rotating shafts, or multiple teeth can be arranged in a toothed pattern around the sprockets. The conveyor belt can be a chain. The first drive structure drives the first rotating shaft to rotate, which in turn drives the chain and the second rotating shaft to move through meshing. When the conveyor belt moves, it drives the carrier plate to move. The side plate on the carrier plate can carry the reaction cup from the discharge port of the hopper. Because the side plate is inclined, the reaction cup has a tendency to slide relative to the side plate. When the side plate moves to the position corresponding to the receiving port, the reaction cup can slide from the side plate into the receiving port.

[0035] 8. The reaction cup feeding device provided by this utility model has a first baffle and a second baffle extending along the moving direction of the conveyor belt at the discharge port of the hopper. The first baffle and the second baffle are connected to the support and form a conveying channel. The conveyor belt is located between the first baffle and the second baffle. The first baffle blocks between the side plate and the receiving port. The reaction cup located on the side plate has a tendency to slide towards the first baffle.

[0036] In this invention, the conveying channel formed by the first and second baffles can prevent the reaction cup from sliding before reaching the receiving port. The reaction cup has a tendency to slide towards the first baffle, so that after the reaction cup leaves the first baffle, it can slide towards the receiving port and enter, thus falling into the slide, so as to facilitate the next step.

Detailed Implementation

[0049] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0051] See Figure 1 , Figure 2 , Figure 3 as well as Figure 7 , Figure 1 This is a three-dimensional structural diagram of the reaction cup feeding device in the embodiment. Figure 2 for Figure 1 A magnified view of a portion of point A in the diagram. Figure 3 for Figure 1 A three-dimensional structural diagram of the feeding device for the reaction vessel from another angle. Figure 7 This is a partial cross-sectional view of the reaction vessel feeding device.

[0052] This embodiment provides a reaction cup feeding device, including: a hopper 1, a conveying structure 2, and a cup-dispensing structure 3.

[0053] The conveying structure 2 includes a conveyor belt 21 that extends partially into the hopper 1, with a plurality of feeding blocks 22 arranged on the conveyor belt 21. It also includes a first drive structure that is drively connected to the conveyor belt 21. The first drive structure is used to drive the conveyor belt 21 to circulate along the height direction so that the feeding blocks 22 transfer the reaction cup 4 in the hopper 1. It also includes a slide 23 that is arranged opposite to the discharge port 11 on the conveying path of the conveyor belt 21. The slide 23 has a receiving port 24 facing the feeding blocks 22.

[0054] The cup-adjusting structure 3 includes a paddle 31 disposed near the slide 23. The end of the paddle 31 swings back and forth in the extension direction of the slide 23 under the drive of the first drive structure to adjust the reaction cup 4 on the slide 23.

[0055] The conveying structure 2 can remove the reaction cup 4 from the hopper 1 through the conveyor belt 21 and multiple feeding blocks 22. Specifically, the first drive structure drives the conveyor belt 21 to move cyclically along the height direction, and the multiple feeding blocks 22 cyclically enter the discharge port 11 of the hopper 1 and carry the reaction cup 4. Then, the reaction cup 4 is transferred to the slide 23 through the receiving port 24. The reaction cup 4 slides in the slide 23 and enters the next stage. The cup-shifting mechanism can correct the cup moving along the slide 23 through the shifting plate 31. Specifically, the first drive structure drives the end of the shifting plate 31 to swing back and forth along the extension direction of the slide 23. The distance between the end of the shifting plate 31 and the slide 23 can be set according to the difference in the length of the reaction cup 4 extending out of the slide 23 in the correct and incorrect postures. This allows the reaction cup 4 in the correct posture to slide smoothly downstream along the slide 23, while the reaction cup 4 in the incorrect posture is blocked and shifted by the shifting plate 31. After being subjected to force, the reaction cup 4 is readjusted to enter the slide 23 in the correct posture, thereby completing the adjustment of the cup posture. This avoids the situation where the cup opening is inverted and the conveyor gets stuck during the conveying process due to irregular feeding of the reaction cup 4, ensuring the continuity of the testing process and improving testing efficiency. In addition, the conveyor belt 21 of the conveying structure 2 and the lever 31 of the cup-pulling mechanism share the first drive structure 32 for power, reducing the number of drive structures, reducing the size of the equipment, reducing energy consumption, and saving costs.

[0056] See Figure 2 , Figure 3 and Figure 5 , Figure 5This is a three-dimensional structural diagram of the reaction vessel feeding device from another angle, specifically showing the installation position of the first rotating shaft 25.

[0057] In this embodiment, the conveying structure 2 includes a first rotating shaft 25 and a second rotating shaft 26. The first rotating shaft 25 is connected to the first driving structure for transmission. It also includes a bracket 27 arranged along the height direction. The first rotating shaft 25 is rotatably disposed at one end of the bracket 27, and the second rotating shaft 26 is rotatably disposed at the other end of the bracket 27. The conveyor belt 21 is wound around the first rotating shaft 25 and the second rotating shaft 26.

[0058] The first rotating shaft 25 and the second rotating shaft 26, which are rotatably set, define the movement path of the conveyor belt 21. The bracket 27 serves as the bearing structure for the first rotating shaft 25 and the second rotating shaft 26. The first driving structure drives the first rotating shaft 25 to rotate, thereby driving the conveyor belt 21 to move. This allows the conveyor belt 21 to move clockwise or counterclockwise around the relative outer edges of the first rotating shaft 25 and the second rotating shaft 26. The loading block 22 located on the conveyor belt 21 can also move clockwise or counterclockwise, thereby achieving a cyclical re-entry into the hopper 1 and transfer of the reaction cup 4.

[0059] See Figure 2 , Figure 4 and Figure 6 , Figure 4 for Figure 3 The enlarged view at point B shows the specific engagement position of the paddle 31 and the slide rail 23. Figure 6 This is a schematic diagram of the structure in which the material receiving port and the conveying structure work together.

[0060] In this embodiment, the dial structure 3 further includes: a gear disk 33, coaxially and fixedly connected to the second rotating shaft 26, the gear disk 33 and the second rotating shaft 26 rotating around the same axis; a rocker arm 34, rotatably mounted on the conveying structure via a pin 35, for example, it can be rotatably mounted on a bracket 27, the first end of the rocker arm 34 having a protrusion 37 that contacts and engages with the teeth 331 of the gear disk 33, the protrusion 37 being cylindrical in shape; the second end being connected to the paddle 31, so that the end of the paddle 31 remains close to the slide rail 23; a return spring 36, one end connected to the conveying structure, for example, it can be connected to the bracket 27, the other end connected to the rocker arm 34 with the connection point located between the pin 35 and the protrusion 37, the return spring 36 having a pre-tension amount, so that the return spring 36 can quickly pull the rocker arm 34 toward the gear disk 33, the surface of the paddle 31 facing the slide rail 23 being a convex arc surface.

[0061] In this invention, the gear disk 33 is coaxially and fixedly connected to the second rotating shaft 26. Since the second rotating shaft 26 is rotatably mounted on the bracket 27, the first drive structure can drive the second rotating shaft 26 to rotate through the first rotating shaft 25 and the conveyor belt 21, so that the gear disk 33 rotates synchronously with the second output shaft. As the outer edge of the gear disk 33 makes a circular motion, the protrusion 37 of the rocker arm 34 sequentially contacts the tip of the gear tooth 331 and the groove between two adjacent gear teeth 331. Since the radial dimension of the tip of the gear tooth 331 is greater than the radial dimension of the bottom of the groove, As the dimensions change, the protrusion 37 will reciprocate towards and away from the center of the gear 33. The first end of the rocker arm 34 swings synchronously with the protrusion 37. When the protrusion 37 slides from the groove to the tip of the tooth 331, the return spring 36 gains elastic potential energy. When the protrusion 37 leaves the tip of the tooth 331, the return spring pulls the first end of the rocker arm 34 towards the center of the gear 33 through elastic force, so that the protrusion 37 gradually slides into the groove, thereby ensuring that the first end of the rocker arm 34 can reciprocate.

[0062] See Figure 3 and Figure 5 In this embodiment, the first driving structure 32 includes a first driving member 321 disposed at the bottom of the bracket 27. The output end of the first driving member 321 is connected to the first rotating shaft via a pulley transmission structure. Specifically, the pulley transmission structure includes a driving wheel 322 rotatably connected to the output end of the first driving member 321, a driven wheel 324 coaxially fixedly connected to the first rotating shaft 25, and a first transmission belt 323 connecting the driving wheel 322 and the driven wheel 324. Of course, other transmission structures besides pulley transmission can also be used to achieve transmission.

[0063] Since the rocker arm 34 is rotatably mounted on the bracket 27 via the pin 35, the second end of the rocker arm 34 can swing in the opposite direction to the first end with the pin 35 as the swing center. This causes the paddle 31 connected to the second end to swing synchronously, so that the end of the paddle 31 swings back and forth in the direction of approaching or moving away from the slide 23. Specifically, when the protrusion 37 slides from the groove to the tip of the tooth 331, the end of the paddle 31 moves away from the slide groove. When the protrusion 37 leaves the tip of the tooth 331, the end of the paddle 31 moves towards the slide groove. After the protrusion 37 is disengaged from the resistance of the tip of the tooth 331, the protrusion 37 can quickly enter the groove under the elastic force of the return spring 36. Since there is a radial dimension difference between the tip of the tooth 331 and the bottom of the groove, the end of the paddle 31 can move quickly towards the slide groove. By using a short burst of force, the reaction cup 4 with the wrong posture is impacted. After being impacted, the reaction cup 4 with the wrong posture will quickly adjust its posture to the correct posture, which improves the effect of correcting the posture of the reaction cup 4.

[0064] It is evident that the combination of the above structures not only enables the toothed disc 33 and the conveyor belt 21 to share the first drive structure, but also improves the correction effect on the reaction cup 4, further solving the problem of conveying jam of the reaction cup 4.

[0065] like Figure 8 As shown, in this embodiment, a limiting plate 341 is provided on one side of the swing arm 34, and a mounting plate 342 parallel to the end face of the limiting plate 341 is provided at the opposite end. The protrusion 37 is mounted on the mounting plate 342 by a pin, and the gear tooth 331 is located between the limiting plate 341 and the mounting plate 342.

[0066] The rocker arm 34 can be elongated. The end face of the rocker arm 34 facing the gear disk 33 is perpendicular to the plane containing the radial direction of the gear disk 33, and the width of the end face facing the gear disk 33 is greater than the thickness of the gear disk 33. The limiting plate 341 and the mounting plate 342 can extend from the opposite sides of the rocker arm 34 towards the gear disk 33 and are perpendicular to the end face of the rocker arm 34. This can limit the gear tooth 331 between the limiting plate 341 and the mounting plate 342, so that the limiting plate 341 and the mounting plate 342 can limit the relative position of the rocker arm 34 and the gear tooth 331, so as to ensure that the protrusion 37 and the gear tooth 331 always maintain a mating relationship and avoid the failure of the paddle 31.

[0067] like Figure 6 As shown, in this embodiment, the rocker arm 34 is provided with an extension 343 parallel to the second rotation axis 26. Specifically, the extension 343 is parallel to the central axis of the second rotation axis 26. The other end of the return spring 36 is connected to the extension 343, and the return spring 36 is located between the gear disk 33 and the conveying structure 2. Specifically, there may be a gap between the gear disk 33 and the conveying structure 2 to facilitate connecting one end of the return spring 36 to the bracket 27 of the conveying structure 2. The extension 343 is coplanar with the rocker arm 34 and extends towards the conveying structure 2, thereby supporting the rocker arm 34 in a position directly opposite the gear disk 33. The extension 343 can be connected to the other end of the return spring 36, so that the return spring 36 is located between the gear disk 33 and the conveying structure 2. This arrangement makes the structure more compact.

[0068] like Figure 6As shown, in this embodiment, a first flange 344 is provided on one side of the swing arm 34, and a second flange 345 is provided at the end of the extension 343 opposite to the swing arm 34. The first flange 344 and the second flange 345 extend in a direction perpendicular to the same end face of the swing arm 34 and the extension 343. The first flange 344 and the second flange 345 are provided with the same through hole. The pin 35 is connected to the bracket 27 of the conveying structure 2 through the through hole of the first flange 344 and the second flange 345, so that the swing arm 34 can swing relative to the conveying structure 2 and achieve reciprocating swing under the cooperation of the gear tooth 331, the protrusion 37 and the return spring 36.

[0069] To avoid missing reaction cup 4 with the pry bar 31, please refer to... Figure 2 , Figure 7 and Figure 8 , Figure 7 This is a partial cross-sectional view of the reaction vessel feeding device. Figure 8 for Figure 7 The enlarged schematic diagram at point C in the middle shows the sliding method of reaction cup 4.

[0070] In this embodiment, a baffle 231 is provided on the slide 23, and the edge of the baffle 231 is provided with a folded edge 232 facing the lever 31.

[0071] The baffle 231 can prevent the reaction cup 4 with incorrect posture from continuing to slide, and the folded edge 232 can block the reaction cup 4 within the effective swing path of the end of the lever 31, so as to avoid the situation where the reaction cup 4 with incorrect posture moves through the swing path of the end of the lever 31 when the end of the lever 31 swings away from the slide 23, and further avoids the situation where the reaction cup 4 enters the downstream stage with incorrect posture.

[0072] See Figure 6 In this embodiment, the conveyor belt 21 is connected to the first rotating shaft 25 and the second rotating shaft 26 through a gear tooth structure of 331 teeth. The loading block 22 includes a carrier plate 221 connected in parallel to the conveyor belt 21, and a side plate 222 that is inclined to the carrier plate 221 relative to the direction of movement of the conveyor belt 21. The side plate 222 is used to transfer the reaction cup 4.

[0073] In this invention, sprockets can be coaxially fixed on the first rotating shaft 25 and the second rotating shaft 26, or multiple teeth can be arranged in a ring around the sprocket teeth 331. The conveyor belt 21 can be a chain. The first drive structure drives the first rotating shaft 25 to rotate, and then drives the chain and the second rotating shaft 26 to move through meshing. When the conveyor belt 21 moves, it will drive the carrier plate 221 to move. The side plate 222 located on the carrier plate 221 can carry the reaction cup 4 from the discharge port 11 of the hopper 1. Since the side plate 222 is inclined, the reaction cup 4 has a tendency to slide relative to the side plate 222. When the side plate 222 moves to the position corresponding to the receiving port 24, the reaction cup 4 can slide from the side plate 222 into the receiving port 24.

[0074] See Figure 6 In this embodiment, the bracket 27 extends obliquely away from the discharge port 11, the bottom of the bracket 27 is located inside the discharge port 11, the top of the bracket 27 exceeds the height of the receiving port 24, and the side plate 222 extends toward the receiving port 24; the slide 23 is obliquely arranged relative to the bracket 27, and the slide 23 is provided with a groove 233 that is directly opposite to the receiving port 24.

[0075] In this invention, the inclined bracket 27 increases the length of the conveyor belt 21 without changing the equipment height, thereby increasing the number of feeding blocks 22 and improving feeding efficiency. After the reaction cup 4 moves to a height exceeding the receiving port 24, it can slide from the side plate 222 into the receiving port 24. The inclined slide 23 facilitates the sliding of the reaction cup 4 by its own weight, eliminating the need for a dragging structure. After passing through the receiving port 24, the reaction cup 4 can directly enter the chute 233. The receiving port 24, positioned directly opposite the chute 233, guides the landing point of the reaction cup 4. After entering the chute 233, the reaction cup 4 slides towards the direction of the lever 31 under its own weight. This arrangement results in a compact structure, and the inclined arrangement increases the length of the conveying path, thereby increasing the number of conveying cups and improving conveying efficiency.

[0076] To ensure the precise placement of reaction cup 4, please refer to [link / reference needed]. Figure 6 A base 241 is provided on the slide 23. The top of the base 241 has a flared opening to form a receiving port 24. The top of the base 241 has a discharge hole 242 facing the slide 233, which connects the receiving port 24 and the slide 233. After the reaction cup 4 slides down to the receiving port 24, it will enter the discharge hole 242 and, guided by the discharge hole 242, enter the slide 233.

[0077] See Figure 8To increase the probability that the reaction cup 4 enters the chute 233 in the correct posture, the reaction cup 4 is provided with a lug 41. The radial dimension of the lug 41 in the reaction cup 4 is greater than the distance between the two walls of the chute 233, so that the lug 41 can be engaged with the outer ends of the two walls of the chute 233. At the same time, the lug 41 divides the outer wall of the reaction cup 4 into two parts of different lengths. The length of the outer wall of the reaction cup 4 near the bottom of the cup is greater than the length near the mouth of the cup, so that the weight of the part between the lug 41 and the bottom of the cup is greater. This part can enter the chute 233 by its own weight.

[0078] See Figure 3 and Figure 5 In this embodiment, the discharge port 11 of the hopper 1 is provided with a first baffle 121 and a second baffle 122 extending along the moving direction of the conveyor belt 21. The first baffle 121 and the second baffle 122 are connected to the support 27 and form a conveying channel. The conveyor belt 21 is located between the first baffle 121 and the second baffle 122. The first baffle 121 blocks between the side plate 222 and the receiving port 24. The reaction cup 4 located on the side plate 222 has a tendency to slide towards the first baffle 121.

[0079] The conveying channel formed by the first baffle 121 and the second baffle 122 can prevent the reaction cup 4 from sliding before reaching the receiving port 24. The reaction cup 4 has a tendency to slide towards the first baffle 121, so that after the reaction cup 4 leaves the first baffle 121, it can slide towards the receiving port 24 and enter, thus falling into the slide 23, so as to facilitate the next step.

[0080] In this embodiment, the bottom of the base 241 is connected to the first baffle 121, and the bracket 27 is provided with an outer protective plate 28 connected to the second baffle 122 through the bottom. After the reaction cup 4 is separated from the blocking range of the first baffle 121 and the second baffle 122, the outer wall of the base 241 and the outer protective plate 28 can still block the sliding of the reaction cup 4, thereby extending the length of the conveying channel and further increasing the feeding quantity.

[0081] To improve material loading efficiency, please refer to... Figure 7 and Figure 9 , Figure 9 for Figure 7 The enlarged schematic diagram at point D in the middle shows the working method of pusher block 51.

[0082] The reaction cup feeding device in this embodiment also includes a pushing structure 5. The pushing structure 5 includes a second driving structure fixedly installed on the hopper 1 and a pushing block 51 that is connected to the second driving structure in a transmission manner. A through hole 13 is provided on the bottom wall of the hopper 1 near the discharge port 11. Under the drive of the second driving structure, the pushing block 51 extends into the through hole 13 and reciprocates along the movement direction of the conveyor belt 21 to push the reaction cup 4 to move in the direction of the conveyor belt 21.

[0083] The second drive structure of this invention can drive the pusher 51 to push the reaction cup 4 into the feeding block 22 of the conveyor belt 21, thereby improving the feeding efficiency. A through hole 13 is provided in the bottom wall of the hopper 1, allowing the second drive structure to be placed outside the hopper 1 without occupying space within it.

[0084] In this embodiment, the end of the pusher block 51 has an inclined surface 511 facing the discharge port 11, which can improve the accuracy of the pushing direction. A guide plate 14 is provided at the bottom of the discharge port 11, and the reaction cup 4 can enter the feeding block 22 along the guide plate 14 under the push of the pusher block 51.

[0085] See Figure 9 In this embodiment, the second driving structure 52 includes a second driving member 521, which is disposed at the bottom of the bracket 27 and is connected to the push block 51 via a slide rail slider structure. Specifically, a mounting bracket 29 is provided at the bottom of the bracket 27, the second driving member 521 is mounted on the mounting bracket 29, and the slide rail slider structure includes a slide rail 526 disposed on the mounting bracket 29 and a slider 524 slidably disposed on the slide rail 526. The push block 51 is fixedly connected to the slider 524. The second driving member 521 can drive the slider 524 to move along the slide rail 526 by means of belt pulley transmission. Specifically, a drive wheel is connected to the output end of the second driving member 521, a transmission wheel 523 is rotatably connected to the mounting bracket 29, the drive wheel and the transmission wheel 523 are connected by a second transmission belt 522, the arrangement direction of the second transmission belt 522 is parallel to the extension direction of the slide rail 526, and the slider 524 is connected to the second transmission belt 522 through a clamping plate 525.

[0086] Secondly, this utility model provides a testing and analysis instrument, including the aforementioned reaction cup feeding device. The testing and analysis instrument also includes a hopper 1 and a cup-supporting structure 6. The reaction cup feeding device is used to transfer the reaction cups in the hopper 1 to the cup-supporting structure 6. Specifically, the inlet of the cup-supporting structure 6 is connected to the slide 23, thereby enabling the reaction cups to be transported to the cup-supporting structure 6 in the correct orientation. The structure, composition, connection methods of each component, and specific working process of the reaction cup feeding device have been described in detail above. Those skilled in the art can clearly understand the specific implementation method of the reaction cup feeding device of this embodiment based on the above description, and will not be repeated here.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
