[0030] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0031] like Figure 2 , 3 As shown in Figures 1 and 11, the present invention provides a cup discharging device for reaction cups, comprising a cup storage bin assembly 2, a material distribution assembly 3, a cup delivery assembly 4 and a cup screening assembly 5. The cup storage bin assembly 2 is provided with a cup outlet and a cup screening opening, and the cup delivery assembly 4 can move up and down and is inserted in the cup delivery opening. The material distribution assembly 3 is built into the cup storage bin assembly 2 and is arranged above the cup delivery assembly 4 to control the discharging flow of the reaction cups 1; the cup screening assembly 5 is installed at the cup outlet of the cup storage bin assembly 2 to remove disordered reaction cups 1 at the cup screening assembly 5. The reaction cups 1 are transferred to the cup screening assembly 5 by the cup delivery assembly 4 that can move up and down to screen the reaction cups 1, so that the reaction cups 1 are orderly output to the outside of the cup storage bin assembly 2, and the material distribution assembly 3 is used to control the discharging flow of the reaction cups 1 to avoid excessive accumulation of reaction cups 1 on the cup delivery assembly 4 and the cup screening assembly 5.

[0032] Specifically, the cup storage bin assembly 2 comprises a cup storage bin 21 , which has an opening at the top, a cup delivery hole at the bottom, and a cup outlet at the side wall.

[0033] Furthermore, the bottom of the cup storage bin 21 is tilted downward in a direction close to the cup delivery hole. By tilting the bottom of the cup storage bin 21 in a direction close to the cup delivery hole, when the reaction cup 1 falls on the bottom of the cup storage bin 21, it will slide along the bottom of the cup storage bin 21 toward the cup delivery hole, thereby preventing the reaction cup 1 from piling up at the bottom of the cup storage bin 21.

[0034] In this embodiment, the cup storage bin assembly 2 also includes a discharge chute 22 inserted in the cup outlet. The discharge chute 22 is provided with a cup outlet groove running through it relative to the cup outlet. The width of the cup outlet groove is greater than the outer diameter of the cup body 11 of the reaction cup 1 and smaller than the outer diameter of the flange 12.

[0035] The material distribution component 3 includes a material distribution part 31, which is rotatably connected to the inner wall of the cup storage bin 21 and divides the internal cavity of the cup storage bin 21 into an upper cup storage cavity and a lower sieve cup cavity, and a material discharge channel connecting the cup storage cavity and the sieve cup cavity is formed between the lower side of the material distribution part 31 and the inner wall of the cup storage bin 21. By providing the material distribution part 31, the cavity in the cup storage bin 21 is divided under the action of the material distribution part 31, and the discharge flow rate of the reaction cup 1 can be adjusted through the variable area discharge channel.

[0036] In this embodiment, the material dividing part 31 includes a first material dividing plate 311 and a second material dividing plate 312 which are arranged to be inclined downward along the material discharge direction. The first material dividing plate 311 can be rotatably connected to the inner wall of the cup storage bin 21, and the second material dividing plate 312 is connected to the lower side of the first material dividing plate 311. A material discharge channel is formed between the other side of the second material dividing plate 312 and the inner wall of the cup storage bin 21, and the inclination angle of the second material dividing plate 312 is greater than that of the first material dividing plate 311.

[0037] It can be understood that the first material dividing plate 311 can be rotatably connected to the inner wall of the cup storage bin 21 via a rotating shaft or a rotating pin.

[0038] In this embodiment, the material distributing component 3 further includes an elastic portion 32 , which is connected to the material distributing portion 31 and the cup storage bin 21 , and is used to provide a rebound force after the material distributing portion 31 rotates.

[0039] like Figure 7As shown, specifically, the elastic part 32 includes a first positioning column 321, a fixing block 322, a second positioning column 323 coaxially arranged with the first positioning column 321, and a return spring 324. In this embodiment, the first positioning column 321 and the second positioning column 323 are both bolts, and the threaded end of the first positioning column 321 passes through the first material dividing plate 311 from bottom to top and is fixedly connected to the first material dividing plate 311, the fixing block 322 is arranged above the first material dividing plate 311 and is connected to the cup storage bin 21, the threaded end of the second positioning column 323 passes through the fixing block 322 from top to bottom and is fixedly connected to the fixing block 322, and the two ends of the return spring 324 are respectively connected to the first material dividing plate 311 and the fixing block 322, and its two ends are respectively sleeved on the first positioning column 321 and the second positioning column 323. When the first material dividing plate 311 rotates under the push of the push rod 45 in the cup delivering assembly 4, the first material dividing plate 311 will squeeze the reset spring 324. When the cup delivering assembly 4 slides downward, the first material dividing plate 311 will reset under the action of the reset spring 324. By setting a fixing block 322, a first positioning column 321 and a second positioning column 323, the reset spring 324 is fixed to prevent the reset spring 324 from bending.

[0040] In this embodiment, the material distributing assembly 3 further includes a stopper 33, which is disposed below the material distributing portion 31 relative to the elastic portion 32 and connected to the inner wall of the cup storage bin 21, and is used to limit the downward rotation of the material distributing portion 31 relative to one side of the elastic portion 32. By providing the stopper 33, firstly, the rotation range of the material distributing portion 31 can be limited; secondly, when the material distributing portion 31 is reset under the action of the elastic portion 32, the material distributing portion 31 can be prevented from hitting the inner wall of the cup storage bin 21, and the sound of the material distributing portion 31 hitting the inner wall of the cup storage bin 21 can be prevented.

[0041] Specifically, the limiting member 33 can be rotatably connected to the inner wall of the cup storage bin 21 and abut against the bottom of one side of the material distributing portion 31 .

[0042] It can be understood that the limiting member 33 can be rotatably connected to the inner wall of the cup storage bin 21 via a rotating shaft or a rotating pin.

[0043] like Figure 4 , 5As shown in FIGS. 8, 9 and 10, the cup delivery assembly 4 includes a cup delivery portion 41 which can be slidably or rotatably inserted into the cup delivery hole of the cup storage bin 2, a driving portion 42 connected to the cup delivery portion 41 and used to drive the cup delivery portion 41 to move up and down, and a correction portion 43 arranged below the cup outlet. The cup delivery portion 41 is provided with a cup delivery groove 41a relative to the cup delivery hole. The cup delivery groove 41a is inclined downward in a direction close to the cup outlet side of the cup storage bin 21, and is open to one side of the cup outlet. The width of the cup delivery groove 41a is greater than the outer diameter of the cup body of the reaction cup 1 and smaller than the outer diameter of the flange. The depth of the cup delivery groove 41a is greater than the length below the flange of the reaction cup 1. The correction portion 43 is arranged relative to the opening side of the cup delivery groove 41a, and its side relative to the cup delivery groove 41a is gradually inclined upward in a direction close to the cup delivery portion 41, so as to correct the reaction cup 1 tilted in the cup delivery groove 41a.

[0044] Furthermore, the cup delivery portion 41 is disposed below the material distribution portion 31 and can push the material distribution portion 31 to rotate, so as to adjust the width of the material discharge channel.

[0045] Specifically, the cup delivery portion 41 is a sheet-shaped plate, and a cup delivery groove 41 a is formed on the top thereof.

[0046] Among them, the unloading chute 22 is provided with a fixing hole relative to the cup feeding part 41, one side of the straightening part 43 is inserted into the fixing hole and arranged relative to the cup feeding part 41, and the other side is connected to the unloading chute 22 through a screw, and the straightening part 43 is located directly below the unloading chute 22.

[0047] During the up and down movement of the cup delivery part 41, the reaction cup 1 falls into the cup delivery groove 41a. Due to the size limitation of the cup delivery groove 41a, the cup body 11 of the reaction cup 1 is inserted into the cup delivery groove 41a and its flange is located above the cup delivery part 41, thereby realizing the orderly screening of the reaction cup 1. When the cup delivery part 41 passes through the cup outlet, the screened reaction cups 1 slide out of the cup outlet in an orderly manner along the guide of the inclined cup delivery groove 41a under the action of gravity; since the reaction cups 1 are disorderly arranged in the cup storage bin 21, some reaction cups 1 may be tilted and stuck at the cup outlet of the cup delivery part 41. When the cup delivery part 41 moves up and down, it drives the reaction cup 1 to move up and down. During the movement of the reaction cup 1, it contacts the adjusting part 43, and the adjusting part 43 pushes the reaction cup 1 to rotate, so that the cup body 11 of the reaction cup 1 is inserted into the cup delivery groove 41a, thereby realizing the adjustment of the reaction cup 1.

[0048] In this embodiment, the cup delivery assembly 4 further includes a base 4a, and the cup storage bin 21 is fixed on the top of the base 4a through a plate body 4b.

[0049] In this embodiment, the driving part 42 includes a guide rail 421 connected to the base 4a along the sliding direction of the cup delivery part 41, a slider 422 slidably connected to the guide rail 421 and connected to the cup delivery part 41, and a driving member 423 connected to the slider 422 and the base 4a, and the driving member 423 is used to drive the slider 422 and the cup delivery part 41 to move along the guide rail 421. When it is necessary to drive the cup delivery part 41 to move, the driving member 423 is started, and the driving member 423 drives the slider 422 and the cup delivery part 41 to move along the guide rail 421, and the up and down movement of the cup delivery part 41 is realized by the driving part 42.

[0050] It is understandable that the driving member 423 can be a cylinder, a hydraulic cylinder, an electric push rod, etc.

[0051] The driving part 42 further includes a support plate 424 connected to the base 4 a . The support plate 424 is vertically arranged. The guide rail 421 is vertically arranged and connected to the support plate 424 .

[0052] like Fig.10 As shown, in this embodiment, the driving member 423 includes two pulleys 4231, a synchronous belt 4232 and a motor 4233. The two pulleys 4231 are parallel to each other and are arranged at intervals. The pulleys 4231 are rotatably connected to the support plate 424 around their own axes. The length direction of the synchronous belt 4232 is parallel to the guide rail 421. The synchronous belt 4232 is transmission-connected to the two pulleys 4231 and one side of it is connected to the slider 422. The motor 4233 is fixed to the support plate and its output shaft is connected to a pulley 4231. When the slider 422 needs to move relative to the guide rail 421, the motor 4233 is started, the motor 4233 drives the pulley 4231 to rotate, the pulley 4231 drives the belt to move, and the belt drives the slider 422 to move. The up and down movement of the slider 422 is controlled by the forward and reverse rotation of the motor 4233.

[0053] In this embodiment, the cup delivering assembly 4 also includes a material prying portion 46 arranged above the cup outlet side of the cup delivering groove 41a, and a connecting portion 44 connecting the cup delivering portion 41 and the material prying portion 46. The connecting portion 44 is connected to the cup delivering portion 41 through a push rod 45, and the push rod 45 is arranged at one end of the connecting portion 44 away from the material prying portion 46. By setting the material-prying part 46, the connecting part 44 and the material-prying part 46 are driven to move up and down during the up and down movement of the cup-delivering part 41. When the cup-delivering assembly 4 moves upward to the cup-delivering groove 41a and docks with the cup outlet of the material-discharging slide 22, if there is a stuck reaction cup 1 at the cup outlet of the material-discharging slide 22, the material-prying part 46 will pry the stuck reaction cup 1 during the downward movement of the cup-delivering assembly 4, thereby avoiding disorderly accumulation of the reaction cups 1 at the outlet of the cup-delivering part 41 and facilitating the reaction cups 1 to slide out of the cup-delivering part 41; when the cup-delivering part 41 slides to the lowest side of its moving trajectory, the material-prying part 46 blocks the cup outlet to push the reaction cup 1 back to the cup storage bin 21. By setting the material-prying part 46, when the cup-delivering part 41 slides downward to the lowest side of its moving track, the cup outlet blocked by the cup-delivering part 41 is gradually exposed. At this time, the reaction cup 1 in the cup storage bin 21 may slide out of the cup outlet in a disorderly manner. In the present application, by setting the material-prying part 46, when the cup-delivering part 41 slides downward to the lowest side of its moving track, the material-prying part 46 component blocks the cup outlet to prevent the reaction cup 1 in the cup storage bin 21 from directly sliding out of the cup outlet.

[0054] It can be understood that the material-moving portion 46 is a long rod body arranged horizontally or vertically, and the connecting portion 44 is a long rod body perpendicular to the material-moving portion 46 . The material-moving portion 46 and the connecting portion 44 are connected by bolts.

[0055] Specifically, a through hole is formed in the vertical direction on one side of the material-prying part 46 away from the connecting part 44. The material-prying part 46 includes a material-stopping rod 461 and a screw 462. The material-stopping rod 461 is arranged below the through hole, and a threaded hole is formed at one end thereof relative to the through hole. The thread of the screw 462 passes through the through hole and is threadedly connected to the threaded hole. By providing the material-stopping rod 461 and the screw 462, a detachable connection with the material-prying part 46 is realized while material-stopping is realized.

[0056] In this embodiment, the cup delivery assembly 4 further includes a rolling portion 47, which is rotatably connected to the top of the connecting portion 44. The rolling portion 47 can reduce the noise generated when the first material distribution plate 311 is hit, and the material distribution assembly 3 is pushed to rotate by the rotatable rolling portion 47, so as to prevent the push rod 45 from scratching or getting stuck on the material distribution assembly 3.

[0057] It can be understood that the rolling portion 47 is in a circular ring shape, and is rotatably connected to the top of the push rod 45 via a rotating shaft or a rotating pin, and the first dividing plate is driven to rotate via the rotatable rolling portion 47 .

[0058] In this embodiment, the outer wall of the cup storage bin 21 is further provided with a mounting hole, and the cup delivery assembly 4 further includes a material shifting block 48, which is installed in the mounting hole and extends into the cup storage bin 21, and the material shifting block 48 is arranged above the cup delivery portion 41 and is arranged relative to the cup delivery portion 41.

[0059] The material-shifting block 48 is in an elongated strip shape and is parallel to the guide of the cup-delivering groove 41 a . The side surface of the material-shifting block 48 relative to the cup-delivering portion 41 is an arc surface that gradually protrudes upward into the cup storage bin 21 .

[0060] During the upward movement of the cup delivery part 41, the reaction cup 1 is pushed to move upward. During the upward movement, the reaction cup 1 accumulated above the cup delivery part 41 contacts the arc surface of the material shifting block 48 and, under the guidance of the arc surface, deviates from the cup delivery part 41 toward the direction of the material discharge port of the material discharge channel, thereby shifting the reaction cup 1 located above the cup delivery part 41 to prevent the reaction cup 1 from being accumulated above the cup delivery part 41.

[0061] like Figure 6 and Fig.11 As shown, the sieve cup assembly 5 includes a discharge block 51, a sieve cup block 52 and an elastic member 53. The discharge block 51 is connected to the cup storage bin 21 and is arranged above the discharge chute 22. The discharge block 51 is provided with a guide groove penetrating the discharge block 51 relative to the cup outlet. The guide groove and the cup outlet groove are used together for discharging materials from the reaction cup 1. The sieve cup block 52 can be movably inserted in the guide groove in a sliding or rotating manner and can slide up and down or rotate relative to the discharge block 51. The bottom surface of the sieve cup block 52 is a sieve cup inclined surface, and the sieve cup inclined surface is inclined downward along the discharge direction of the cup outlet. The elastic member 53 is connected to the sieve cup block 52 and the discharge block 51, and is used to provide a rebound force after the sieve cup block 52 slides.

[0062] Among them, the elastic member 53 is a compression spring or a torsion spring. It can be understood that when the elastic member 53 is a compression spring, the cup feeding part 41 rises, and the reaction cups accumulated on the cup feeding part 41 will push the screen cup block 52 upward. In order to prevent the distance between the screen cup block 52 and the cup outlet from being greater than the length of a cup when the screen cup block 52 moves upward, thereby causing the reaction cup to fly out, a limit member 52a such as a limit light sensor can be set on the screen cup assembly 5 along the direction of movement of the screen cup block 52 to avoid collision caused by the movement of the screen cup block 52 or disordered reaction cups flowing out of the opening of 51.

[0063] When the sieve cup block 52 is located at the initial position, the distance between the sieve cup block and the discharge block 51 is smaller than the distance between the cup bottom and the flange.

[0064] By setting the sieve cup assembly 5, when the reaction cup 1 is reversely inserted into the cup delivery groove 41a, the cup bottom 112 of the cup delivery groove 41a is located above the cup top 111. Due to the limitation of the flange 12, the length of the cup body 11 above the flange 12 is greater than the length of the cup body 11 below the flange 12. When the inverted reaction cup 1 passes through the cup outlet, the cup bottom 112 abuts against the sieve cup inclined surface of the sieve cup block 52. As the cup delivery part 41 continues to rise, the reaction cup 1 rotates along the sieve cup inclined surface. When the cup delivery part 41 slides down, due to the limitation of the sieve cup block 52, the sliding reaction cup 1 is stuck by the sieve cup block 52, so that the inverted reaction cup 1 is removed from the cup delivery part 41, and the inverted reaction cup 1 is prevented from passing through the cup outlet.

[0065] The specific working process of the present invention is as follows: the reaction cup 1 is introduced into the cup storage bin 21 through the upper opening of the cup storage bin 21, and under the action of the first dividing plate 311 and the second dividing plate 312, the reaction cup 1 enters the bottom of the storage bin at a certain flow rate. Under the guidance of the bottom of the storage bin, the reaction cup 1 rolls to the cup delivery port and rolls into the cup delivery groove 41a through the cup delivery port. Since the size of the flange is larger than the width of the cup delivery groove 41a, the bottom or top of the reaction cup 1 is inserted into the cup delivery groove 41a, thereby realizing the preliminary screening of the reaction cup 1 and the preparation of the cup delivery.

[0066] The driving part 42 is started, and the driving part 42 drives the cup delivery part 41 to slide up and down. During the upward sliding of the cup delivery part 41, the cup delivery part 41 drives the reaction cup 1 in the cup delivery groove 41a to move upward. When the opening of one side of the cup delivery groove 41a is opposite to the cup outlet, the reaction cup 1 in the cup delivery groove 41a slides into the cup outlet groove of the unloading slide 22 under the action of gravity, thereby realizing the orderly discharge of the reaction cup 1; during the upward and downward movement of the cup delivery part 41, the push rod 45, the connecting part 44 and the material prying part 46 are driven to move up and down. The push rod 45, the connecting part 44 and the material prying part 46 that move up and down can push away the reaction cup 1 located above the cup delivery groove 41a. In the process of pushing away the reaction cup 1, the reaction cup 1 in the cup storage bin 21 will be stirred, so that the reaction cup 1 slides into the cup delivery groove 41a.

[0067] When the rolling portion 47 on the push rod 45 slides to abut against the first material dividing plate 311, the rolling portion 47 pushes the first material dividing plate 311 to rotate, and the first material dividing plate 311 drives the second material dividing plate 312 to rotate. During the rotation of the second material dividing plate 312, the width of the discharge channel between the second material dividing plate 312 and the cup storage bin 21 becomes larger, so that the reaction cup 1 on the second material dividing plate 312 accelerates to slide downward, and the discharge flow rate of the first material dividing plate 311 and the second material dividing plate 312 can be changed by the cup feeding portion 41 sliding up and down.

[0068] The return spring 324 is compressed during the rotation of the first dividing plate 311. When the cup feeding part 41 slides downward, the first dividing plate 311 rotates to the initial position under the action of the return spring 324 until the first dividing plate 311 abuts against the limiter 33 and stops rotating, thereby realizing the reset of the first dividing plate 311 and the second dividing plate 312.

[0069] Since the reaction cups 1 may be arranged in disorder in the cup storage bin 21, some of the reaction cups 1 may be tilted and stuck in the cup delivery groove 41a. When the cup delivery part 41 moves up and down, it drives the reaction cup 1 to move up and down. During the movement, the reaction cup 1 contacts the adjustment part 43. The adjustment part 43 pushes the reaction cup 1 to rotate around the flange, so that the cup body 11 of the reaction cup 1 is inserted into the cup delivery groove 41a, thereby achieving the adjustment of the reaction cup 1.

[0070] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
