However, after drying, a small amount of water still remains on the inner wall of the dialysis bucket to varying degrees, and the location of the water residue varies from container to container.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Example 1

[0034] Figures 1 to 4 An embodiment of the container residual liquid discharge device of the present invention is shown. The container residual liquid discharge device of this embodiment includes a transition conveying track 1 and a support 2 disposed on one side of the transition conveying track 1. The support 2 is provided with a container clamping mechanism 3, a first rotating mechanism 4 and a second rotating mechanism 5 for driving the container clamping mechanism 3 to rotate, a lifting mechanism 6 for driving the container clamping mechanism 3 to rise and fall, and a retractable suction tube 7. The rotation axis of the first rotating mechanism 4 is arranged vertically, the rotation axis of the second rotating mechanism 5 is arranged parallel to the transition conveying track 1, and the suction tube 7 is arranged at an angle.

[0035] The container residual liquid discharge device of this embodiment is equipped with an independent transition conveying track 1, which does not interfere with the working rhythm of upstream and downstream equipment and avoids affecting the efficiency of upstream and downstream equipment. When it is necessary to discharge the residual liquid in the container 8, the lifting mechanism 6 drives the container clamping mechanism 3 to descend so that the container clamping mechanism 3 can clamp the container 8. The lifting mechanism 6 drives the container clamping mechanism 3 to rise, so that the container 8 is separated from the transition conveying track 1, so that the transition conveying track 1 can avoid the container 8 from being obstructed from rotating. Then, the first rotating mechanism 4 and the second rotating mechanism 5 respectively drive the container clamping mechanism 3 to rotate at a set angle, so that the residual liquid in the container 8 is collected at the lowest point of the container 8, so that the suction tube 7 can suck out all the residual liquid. Finally, the inclined suction tube 7 extends into the lowest point of the inclined container 8 to suck out the residual liquid. It has a high degree of automation, reasonable and effective structure, and can fully discharge the residual liquid. In this embodiment, the container 8 is a dialysis bucket, with rotation angles of 15° to 25° in both directions. The inclination angle of the pipette 7 to the ground is 30° to 40°. The small angle between the pipette 7 and the dialysis bucket facilitates the pipette 7 in drawing out all the residual liquid collected at the lowest point of the dialysis bucket. Of course, in other embodiments, the rotation angle can be adjusted appropriately depending on the type of container 8.

[0036] In a preferred embodiment, the container clamping mechanism 3 is connected to the first rotating mechanism 4, the first rotating mechanism 4 is connected to the second rotating mechanism 5, and the second rotating mechanism 5 is connected to the lifting mechanism 6. During operation, the first rotating mechanism 4 drives the container clamping mechanism 3 and the container 8 it clamps to rotate; the second rotating mechanism 5 drives the first rotating mechanism 4 and the container clamping mechanism 3 to rotate; and the lifting mechanism 6 drives the container clamping mechanism 3, the first rotating mechanism 4, and the second rotating mechanism 5 to rise and fall as a whole. This structure is reasonable and effective. Of course, in other embodiments, the connection relationships between the first rotating mechanism 4, the second rotating mechanism 5, and the lifting mechanism 6 and the container clamping mechanism 3 can also be adjusted. For example, the lifting mechanism 6 can directly drive the container clamping mechanism 3 to rise and fall, the first rotating mechanism 4 can drive the lifting mechanism 6 to rotate, and the second rotating mechanism 5 can drive the first rotating mechanism 4 to rotate, etc.

[0037] Furthermore, in this embodiment, multiple container clamping mechanisms 3 and a first rotating mechanism 4 are provided and connected one-to-one. The multiple container clamping mechanisms 3 are distributed at intervals along the length of the transition conveying track 1, and multiple suction tubes 7 are provided and arranged one-to-one with the multiple container clamping mechanisms 3. After the multiple containers 8 are transferred to the transition conveying track 1, the multiple container clamping mechanisms 3 clamp the multiple containers 8 one-to-one. The first rotating mechanism 4 drives the corresponding container clamping mechanism 3 to rotate, and the second rotating mechanism 5 drives all the container clamping mechanisms 3 to rotate. After the containers 8 reach the required tilt state, the multiple suction tubes 7 extend into the lowest point of the multiple containers 8 one-to-one, thereby realizing the suction of residual liquid in the multiple containers 8 and further improving efficiency.

[0038] Furthermore, in this embodiment, the container clamping mechanism 3 includes grippers 31 arranged opposite to each other on both sides of the container 8, and a clamping drive member 32 for driving the grippers 31 on both sides to move closer or further apart. The clamping drive member 32 is connected to the first rotating mechanism 4. After the container clamping mechanism 3 is lowered into position, the clamping drive member 32 drives the grippers 31 on both sides to move closer together, thereby reliably clamping and fixing the container 8. Then, the container clamping mechanism 3 is raised, and after the distance between the container 8 and the transition conveying track 1 reaches a set height, the first rotating mechanism 4 can drive the grippers 31 and the container 8 to rotate through the clamping drive member 32.

[0039] Furthermore, in this embodiment, the first rotating mechanism 4 includes a rotary cylinder 41 and a cylinder mounting base 42. The rotary cylinder 41 is mounted on the second rotating mechanism 5 (specifically, on the rotating shaft 51 of the second rotating mechanism 5) via the cylinder mounting base 42. The clamping drive component 32 is a telescopic cylinder, and the output end of the rotary cylinder 41 is connected to the cylinder body of the telescopic cylinder. The rotary cylinder 41 can drive the telescopic cylinder to rotate, and the second rotating mechanism 5 can drive the rotary cylinder 41 to rotate via the cylinder mounting base 42. The structure is simple and effective. Of course, in other embodiments, the clamping drive component 32 and the first rotating mechanism can also take other forms, such as a motor, a cam mechanism, an electric telescopic rod, etc., which will not be described in detail here.

[0040] Furthermore, in this embodiment, the second rotating mechanism 5 includes a rotating shaft 51, a rotating drive component 52, and a connecting component 53. The rotating drive component 52 is a telescopic structure and is hinged to one end of the connecting component 53, while the other end of the connecting component 53 is fixedly connected to the rotating shaft 51. During operation, the rotating drive component 52 extends and retracts, thereby driving the rotating shaft 51 to rotate via the connecting component 53. The structure is simple and effective. Preferably, the rotating drive component 52 is a telescopic cylinder, sharing a power source with the clamping drive component 32 and the rotating cylinder 41. The connecting component 53 is a connecting block, which can transmit a larger driving force.

[0041] Furthermore, in this embodiment, the lifting mechanism 6 includes a lifting seat 61 and a lifting drive component 62. The lifting drive component 62 is mounted on the bracket 2 and connected to the lifting seat 61. A lifting guide structure 63 is provided between the lifting seat 61 and the bracket 2. The rotating shaft 51 and the rotating drive component 52 are mounted on the lifting seat 61. During operation, the lifting drive component 62 can drive the lifting seat 61 to rise and fall. The lifting guide structure 63 provides guidance, ensuring that the lifting process of the lifting seat 61 is smooth and stable, avoiding deviation, and reducing frictional resistance. The rotating shaft 51, the first rotating mechanism 4, etc., mounted on the lifting seat 61 can rise and fall synchronously with the lifting seat 61, making the structure reasonable and effective. The lifting guide structure 63 can be, for example, a guide rail and slider structure, a guide post and guide sleeve structure, a guide rail and roller structure, etc. Preferably, the lifting drive component 62 is a cylinder. Of course, in other embodiments, a screw and nut pair, a synchronous belt mechanism, etc., can also be used.

[0042] Furthermore, in this embodiment, the container residual liquid discharge device also includes a straw drive component 71 and a tilt adjustment component 72. Both the straw drive component 71 and the tilt adjustment component 72 are telescopic structures. The straw drive component 71 is arranged at an angle and its lower end is hinged to the support 2. The upper end of the straw drive component 71 is hinged to the upper end of the tilt adjustment component 72, and the lower end of the tilt adjustment component 72 is hinged to the support 2. A telescopic guide structure 73 is provided between the straw 7 and the straw drive component 71. The straw drive component 71 can drive the straw 7 to extend or retract, thereby entering or exiting the container 8. The telescopic guide structure 73 provides guidance for the extension and retraction of the straw 7, ensuring the accuracy of the movement and preventing deviation. The tilt adjustment component 72, through extension and retraction, can drive the upper end of the straw drive component 71 to swing, thereby adjusting the tilt angle to adapt to containers 8 of different specifications. The structure is simple and effective. The telescopic guide structure 73 can be a guide rail and slider structure, a guide post and guide sleeve structure, etc., and the tilt adjustment component 72 can be a rod structure with threaded connection at both ends, which is convenient to adjust and can provide reliable support for the straw drive component 71.

[0043] Furthermore, in this embodiment, the support 2 is provided with a position adjustment seat 21 and a translation drive 22 for driving the position adjustment seat 21 closer to or further away from the transition conveying track 1. A translation guide structure 23 is provided between the position adjustment seat 21 and the support 2. The straw drive 71 and the tilt adjustment 72 are both provided on the position adjustment seat 21. The translation drive 22 can drive the position adjustment seat 21 to move, and the translation guide structure 23 can provide guidance, making the translation process smoother and more stable, avoiding deviation, and reducing motion resistance. The straw drive 71, the tilt adjustment 72, and the straw 7, etc., move together with the position adjustment seat 21, so that the straw 7 can be adapted to containers 8 of different sizes. Among them, the translation drive 22 is preferably a cylinder, which can share the power air source with the clamping drive 32 and the rotary cylinder 41. Of course, in other embodiments, it can also be an electric push rod, a synchronous belt mechanism, a sprocket and chain mechanism, etc., which will not be described in detail. The translation guide structure 23 can be a guide rail and slider structure, a guide post and guide sleeve structure, etc.

[0044] Example 2

[0045] The residual liquid discharge method of the container residual liquid discharge device described in this embodiment includes the following steps:

[0046] S1, Container 8 is transferred to the transition conveyor track 1;

[0047] S2. The lifting mechanism 6 drives the container clamping mechanism 3 to descend, the container clamping mechanism 3 clamps the container 8, and then the lifting mechanism 6 drives the container clamping mechanism 3 to rise, so that the container 8 is separated from the transition conveying track 1.

[0048] S3, the first rotating mechanism 4 and the second rotating mechanism 5 respectively drive the container clamping mechanism 3 to rotate by a set angle, so that the residual liquid in the container 8 is collected at the lowest point of the container 8; it should be noted that the rotation order of the first rotating mechanism 4 and the second rotating mechanism 5 is not limited. It can be that the first rotating mechanism 4 rotates first and the second rotating mechanism 5 rotates later, or the second rotating mechanism 5 rotates first and the first rotating mechanism 4 rotates later, or the two rotate synchronously.

[0049] S4. Insert the pipette 7 into the lowest part of the container 8 to suck out the residual liquid.

[0050] The residual liquid discharge method of the container residual liquid discharge device in this embodiment can make the residual liquid in the container 8 collect at the lowest point of the container 8, and then suck out the residual liquid by inserting the suction tube 7 into the lowest point of the tilted container 8. It has a high degree of automation, high efficiency and good reliability.

[0051] After all the residual liquid is sucked out, the pipette drive 71 drives the pipette 7 to exit the container 8, and the first rotating mechanism 4 and the second rotating mechanism 5 rotate in opposite directions to reset, so that the container 8 returns to the upright state. Then the lifting mechanism 6 drives the container 8 to descend until the container 8 falls on the transition conveying track 1. Finally, the container clamping mechanism 3 is released, and the lifting mechanism 6 drives the container clamping mechanism 3 to rise and reset, preparing for the next work cycle.

[0052] While the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the invention. Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the scope of the present invention, should fall within the protection scope of the present invention.
