[0048] Optionally, in this embodiment, the upper ends of the first material receiving channel 241, the second material receiving channel, the third material receiving channel 5281 and the fourth material receiving channel 711 are fixedly connected with a feed pipe 242 to facilitate receiving blood collection tubes, and the structure is more convenient and reasonable.

[0049] See also Figures 7 to 9The transfer and folding mechanism 40 includes: a second mounting frame 41 and a first variable distance bearing mechanism 42, and the first variable distance bearing mechanism 42 includes: a third limit baffle 421, a fourth limit baffle 422, a first cross telescopic frame 423, a fifth linear drive 424, a sixth linear drive 425, a third material discharge and pushing assembly 426, at least three fifth mobile receiving seats 427, and a fifth material blocking assembly 428 corresponding to the fifth mobile receiving seats 427. The second mounting frame 41 is fixed on the frame 10a, and the second mounting frame 41 is located directly below the first mounting frame 21. The third limit baffle 421 and the fourth limit baffle 422 are both fixed on the second mounting frame 41 in the left-right direction, and the third limit baffle 421 is spaced apart and located in front of the fourth limit baffle 422. The fifth movable material receiving seat 427 is arranged between the third limiting baffle 421 and the fourth limiting baffle 422 in sequence from front to back, and the fifth movable material receiving seat 427 is parallel to the third limiting baffle 421, and the fifth movable material receiving seat 427 has a second dispersed position away from each other and a second folded position close to each other. Therefore, all the fifth movable material receiving seats 427 are restricted to move between the third limiting baffle 421 and the fourth limiting baffle 422 through the limiting blocking action of the third limiting baffle 421 and the fourth limiting baffle 422. A plurality of second material receiving channels are formed on the fifth movable material receiving seat 427, and the second material receiving channels are used to accommodate the blood collection tubes. The inner diameter of the second material receiving channel is equal to the inner diameter of the first material receiving channel 241, and the number of the second material receiving channels is equal to the number of the first material receiving channels 241. The telescopic direction of the first cross telescopic frame 423 is arranged along the front-to-back direction. The first cross telescopic frame 423 has a first cross connection 4231 that corresponds to the fifth mobile receiving seat 427 and is sequentially distributed along the telescopic direction. The fifth mobile receiving seat 427 is connected to the corresponding first cross connection 4231 in a one-to-one manner. Among them, the specific structure and working principle of the first cross telescopic frame 423 are conventional technical means well known to those skilled in the art. For example, the first cross telescopic frame 423 can be selected to be composed of a plurality of mutually hinged connecting rods, but it is not limited to this. It is within the protection scope of the present invention, so it is not repeated in detail here. The fifth linear drive 424 and the sixth linear drive 425 can both be selected as cylinders, but it is not limited to this. The fifth linear drive 424 and the sixth linear drive 425 are both fixed on the second mounting frame 41 along the front-to-back direction. The fifth mobile receiving seat 427 located at the front side is connected to the driving end of the fifth linear drive 424, and the fifth mobile receiving seat 427 located at the rear side is connected to the driving end of the sixth linear drive 425.Therefore, when the fifth linear driver 424 and the sixth linear driver 425 drive the fifth mobile receiving seat 427 at the front and the fifth mobile receiving seat 427 at the rear, respectively, the remaining fifth mobile receiving seats 427 can be synchronously driven to move away from or close to each other to the second dispersed position or the second retracted position by driving the first cross telescopic frame 423 to stretch or compress. The fifth material blocking assembly 428 is correspondingly arranged at the bottom of the fifth mobile receiving seat 427, so as to prevent the blood collection tubes received by the fifth mobile receiving seat 427 from falling. Furthermore, the third material discharge push assembly 426 is arranged on the second mounting frame 41. When the fifth movable material receiving seat 427 moves to the second dispersing position, and the first movable material receiving seat 24a, the second movable material receiving seat 24b, the third movable material receiving seat 24c and the fourth movable material receiving seat 24d move to the first folding position, the second material receiving channels are vertically aligned one by one directly below the first material receiving channel 241, so that the blood collection tubes released from the first material receiving channel 241 can fall into the second material receiving channels one by one. When the fifth movable material receiving seat 427 moves to the second folding position, all the second material receiving channels are folded to the second folding spacing in the front-to-back direction, and the third material discharge and pushing assembly 426 can drive the fifth material blocking assembly 428 on all the fifth movable material receiving seats 427 to release the blood collection tubes received by all the second material receiving channels on the corresponding fifth movable material receiving seats 427. Then, the driving end of the fifth linear driver 424 pulls the fifth movable material receiving seat 427 located at the front side to move forward, and the driving end of the sixth linear driver 425 pulls the fifth movable material receiving seat 427 located at the rear side to move backward, and the remaining fifth movable material receiving seats 427 are pulled away from each other by the first cross telescopic frame 423 until all the fifth movable material receiving seats 427 move to the second dispersed position, and the blood collection tubes released from the first material receiving channel 241 can be obtained by the second material receiving channel on the fifth movable material receiving seat 427. Then, the driving end of the fifth linear driver 424 pushes the fifth movable material receiving seat 427 located at the front side to move backward, and the driving end of the sixth linear driver 425 pushes the fifth movable material receiving seat 427 located at the rear side to move forward, until all the fifth movable material receiving seats 427 move to the second folded position, and then the third material discharge pushing assembly 426 drives the fifth material blocking assembly 428 on all the fifth movable material receiving seats 427 to release the blood collection tubes received by all the second material receiving channels on the corresponding fifth movable material receiving seats 427.

[0050] See also Figures 7 to 9The fifth material blocking assembly 428 includes: a fifth material blocking plate 4281, a fifth elastic pushing assembly 4282, a first limiting rod 4283 and a first limiting cap 4284. The fifth material blocking plate 4281 is movable along the left and right directions and is arranged at the bottom of the fifth movable material receiving seat 427. The fifth material blocking plate 4281 is formed with a fifth material passing hole 42811 corresponding to the second material receiving channel one by one, and the inner diameter of the fifth material passing hole 42811 is equal to the inner diameter of the second material receiving channel; the fifth material blocking plate 4281 has a fifth material discharging position and a fifth material blocking position in the moving direction. When the fifth material blocking plate 4281 moves to the fifth material discharging position, the fifth material passing hole 42811 is correspondingly opposite to the lower end of the corresponding second material receiving channel, and the blood collection tube in the second material receiving channel can fall down from the fifth material passing hole 42811. When the fifth material stopper plate 4281 moves to the fifth material stopper position, the fifth material passing hole 42811 is misaligned at the lower end of the second material receiving channel. At this time, the fifth material stopper plate 4281 blocks the lower end of the second material receiving channel to block the blood collection tube in the second material receiving channel. Furthermore, the fifth elastic push component 4282 is arranged on the fifth movable material receiving seat 427, and the fifth elastic push component 4282 elastically drives the fifth material stopper plate 4281 to move to the fifth material stopper position. In detail, in this embodiment, the specific structure of the fifth elastic push component 4282 can be selected as an elastic push structure that pushes a slider against the fifth material stopper plate 4281 through a spring elastic push, so as to realize elastically driving the fifth material stopper plate 4281 to move to the fifth material stopper position, so that the fifth material stopper plate 4281 can automatically reset and move to the fifth material stopper position, and the structure is simpler and more reasonable. The upper end of the first limiting rod 4283 is vertically fixedly connected to the bottom of the fifth movable material receiving seat 427, and a first elongated limiting hole 42812 is formed on the fifth material blocking plate 4281 which vertically penetrates therethrough.

The moving stroke of the fifth material baffle plate 4281 is limited by the limiting cooperation between the first limiting rod 4283 and the first elongated limiting hole 42812, and the fifth material baffle plate 4281 is limited between the bottom of the fifth movable material receiving seat 427 and the first limiting cap 4284 by the first limiting cap 4284 to prevent the fifth material baffle plate 4281 from falling out downward, and the structure is safer and more reasonable.

[0051] See also Figures 7 to 9The third material discharge pushing assembly 426 includes: a seventh linear driver 4261 and a third push plate 4262. The seventh linear driver 4261 can be selected as a cylinder, but it is not limited thereto. The seventh linear driver 4261 is fixed to the second mounting frame 41 along the left-right direction, and the third push plate 4262 is fixedly connected to the driving end of the seventh linear driver 4261. When the fifth movable receiving seat 427 moves to the second folded position, the third push plate 4262 simultaneously pushes the fifth baffle plates 4281 on all the fifth movable receiving seats 427 to move to the fifth material discharge position. In this way, the fifth baffle plates 4281 on all the fifth movable receiving seats 427 are pushed at the second folded position to release the blood collection tubes received by the second receiving channels on the corresponding fifth movable receiving seats 427, and the structure is simpler and more reasonable.

[0052] See also Figure 7 Preferably, the first variable-distance bearing mechanism 42 also includes: a fifth stopper 429a, a sixth stopper 429b, a seventh stopper 429c and an eighth stopper 429d, the fifth stopper 429a and the sixth stopper 429b are both fixed on the second mounting frame 41, the seventh stopper 429c is fixed on the frontmost fifth movable material receiving seat 427, and the eighth stopper 429d is fixed on the rearmost fifth movable material receiving seat 427; when the fifth movable material receiving seat 427 moves to the second folded position, the seventh stopper 429c abuts against the front side of the fifth stopper 429a, and the eighth stopper 429d abuts against the rear side of the sixth stopper 429b. Thus, through the limiting and blocking effect of the first stop block 37a and the second stop block 37b, the fifth linear driver 424 is prevented from driving the fifth movable material receiving seat 427 at the front side to move excessively, and the sixth linear driver 425 is prevented from driving the fifth movable material receiving seat 427 at the rear side to move excessively, thereby avoiding collision damage between all the fifth movable material receiving seats 427 when they approach each other and move to the second folded position, and the structure is safer and more reasonable.

However, the number of first variable-distance bearing mechanisms 42 is not limited thereto, and those skilled in the art can flexibly select according to actual use requirements, all within the scope of protection of the present invention, and therefore, will not be described in detail here.

The fifth limit baffle 521 and the sixth limit baffle 522 are both fixed on the third mounting frame 51 along the front-to-back direction, and the fifth limit baffle 521 and the sixth limit baffle 522 are arranged to be spaced apart along the left-right direction. The sixth movable material receiving seat 528 is sequentially moved along the left and right directions and arranged between the fifth limiting baffle 521 and the sixth limiting baffle 522, and the sixth movable material receiving seat 528 is parallel to the fifth limiting baffle 521, and the sixth movable material receiving seat 528 has a third dispersed position away from each other and a third retracted position close to each other. Therefore, all the sixth movable material receiving seats 528 are restricted to move between the fifth limiting baffle 521 and the sixth limiting baffle 522 through the limiting blocking action of the fifth limiting baffle 521 and the sixth limiting baffle 522. The sixth movable material receiving seat 528 is formed with a plurality of vertically penetrating third material receiving channels 5281, and the third material receiving channels 5281 are used to accommodate blood collection tubes. The inner diameter of the third material receiving channel 5281 is equal to the inner diameter of the second material receiving channel, and the number of the third material receiving channels 5281 is equal to the number of the second material receiving channels. The telescopic direction of the second cross telescopic frame 523 is arranged along the left-right direction. The second cross telescopic frame 523 has a second cross connection 5231 that corresponds to the sixth movable material receiving seat 528 and is sequentially distributed along the telescopic direction. The sixth movable material receiving seat 528 is connected to the corresponding second cross connection 5231 in a one-to-one correspondence. Among them, the specific structure and working principle of the second cross telescopic frame 523 are conventional technical means well known to those skilled in the art. For example, the second cross telescopic frame 523 can be selected to be composed of a plurality of mutually hinged connecting rods, but it is not limited to this. It is within the protection scope of the present invention, so it is not described in detail here. The third limit assembly is arranged between the sixth movable material receiving seat 528 adjacent to the fifth limit baffle 521 and the fifth limit baffle 521, so as to limit the maximum moving distance between the sixth movable material receiving seat 528 adjacent to the fifth limit baffle 521 and the fifth limit baffle 521 in the left-right direction through the third limit assembly. The fourth limiting component is arranged between the two sixth movable material receiving seats 528 closest to the fifth limiting baffle 521, so as to limit the maximum moving distance between the two sixth movable material receiving seats 528 closest to the fifth limiting baffle 521 in the left-right direction through the fourth limiting component.The eighth linear drive 524 can be selected as a cylinder, but it is not limited thereto. The eighth linear drive 524 is fixed on the fifth limit baffle 521 in the left-right direction, and the sixth movable material receiving seat 528, which is the second closest to the fifth limit baffle 521, is connected to the driving end of the eighth linear drive 524.

Furthermore, the fourth material discharge and pushing assembly 527 is arranged on the third mounting frame 51. When the sixth movable material receiving seat 528 moves to the third dispersing position and the fifth movable material receiving seat 427 moves to the second folding position, the third material receiving channels 5281 are vertically aligned with the second material receiving channels directly below, so that the blood collection tubes released from the second material receiving channels can fall into the third material receiving channels 5281 in a one-to-one correspondence. When the sixth movable material receiving seat 528 moves to the third folded position, the sixth movable material receiving seat 528 adjacent to the fifth limit baffle 521 abuts against the fifth limit baffle 521, and all third material receiving channels 5281 are folded to the third folded spacing along the left and right directions. The fourth material discharge pushing assembly 527 can drive the sixth material blocking assembly 529 on all the sixth movable material receiving seats 528 to release the corresponding blood collection tubes received by all the third material receiving channels 5281 on the sixth movable material receiving seat 528. Then, the driving end of the eighth linear drive 524 pushes the sixth movable material receiving seat 528, which is the second closest to the fifth limit baffle 521, to move in the direction away from the fifth limit baffle 521. When the distance between the sixth movable material receiving seat 528 adjacent to the fifth limit baffle 521 and the fifth limit baffle 521 reaches the limiting stroke of the third limiting component, the third limiting component limits and prevents the sixth movable material receiving seat 528 adjacent to the fifth limit baffle 521 from moving in the direction away from the fifth limit baffle 521. The driving end of the eighth linear drive 524 continues to push the sixth movable material receiving seat 528, which is the second closest to the fifth limit baffle 521, to move in the direction away from the fifth limit baffle 521. The fifth limit baffle 521 moves in the direction of the second cross telescopic frame 523, so that the second cross telescopic frame 523 expands and extends to pull all the sixth movable material receiving seats 528 to move away from each other until the distance between the two sixth movable material receiving seats 528 closest to the fifth limit baffle 521 reaches the limit stroke of the fourth limit component. The fourth limit component limits and prevents the sixth movable material receiving seat 528 closest to the fifth limit baffle 521 from moving in the direction away from the fifth limit baffle 521. All the sixth movable material receiving seats 528 are moved to the third dispersed position, and the third material receiving channel 5281 on the sixth movable material receiving seat 528 can receive the blood collection tube.Then, the driving end of the eighth linear drive 524 pushes the sixth movable material receiving seat 528, which is the second closest to the fifth limit baffle 521, to move toward the fifth limit baffle 521, so that the distance between the two sixth movable material receiving seats 528 closest to the fifth limit baffle 521 is continuously reduced, and the second cross telescopic frame 523 can be driven to close and shorten to pull all the sixth movable material receiving seats 528 to move closer to each other until the sixth movable material receiving seat 528 adjacent to the fifth limit baffle 521 abuts against the fifth limit baffle 521, so that all the sixth movable material receiving seats 528 move to the third folded position, and then the fourth material discharge pushing assembly 527 drives the sixth material blocking assembly 529 on all the sixth movable material receiving seats 528 to release the corresponding blood collection tubes received by the third material receiving channel 5281 on the sixth movable material receiving seat 528.

When the sixth material blocking plate 5291 moves to the sixth material discharging position, the sixth material passing hole 52911 is correspondingly opposite to the lower end of the corresponding third material receiving channel 5281, and the blood collection tube in the third material receiving channel 5281 can fall down from the sixth material passing hole 52911. When the sixth material stopper plate 5291 moves to the sixth material stopper position, the sixth material passing hole 52911 is misaligned at the lower end of the third material receiving channel 5281. At this time, the sixth material stopper plate 5291 blocks the lower end of the third material receiving channel 5281 to block the blood collection tube in the third material receiving channel 5281. The sixth elastic push component 5292 is arranged on the sixth movable material receiving seat 528, and the sixth elastic push component 5292 elastically drives the sixth material stopper plate 5291 to move to the sixth material stopper position. The specific structure of the sixth elastic push component 5292 can be selected as an elastic push structure that pushes a slider against the sixth material stopper plate 5291 through a spring elastic push, so as to realize elastically driving the sixth material stopper plate 5291 to move to the sixth material stopper position, so that the sixth material stopper plate 5291 can automatically reset and move to the sixth material stopper position, and the structure is simpler and more reasonable.

The ninth linear driver 5271 is fixed to the third mounting frame 51 along the front-back direction, and the fourth push plate 5272 is fixedly connected to the driving end of the ninth linear driver 5271. When the sixth movable receiving seat 528 moves to the third folded position, the fourth push plate 5272 simultaneously pushes the sixth blocking plates 5291 on all the sixth movable receiving seats 528 to move to the sixth material discharge position. In this way, the sixth blocking plates 5291 on all the sixth movable receiving seats 528 are pushed at the third folded position to release the blood collection tubes received by the third receiving channel 5281 on the corresponding sixth movable receiving seat 528, and the structure is simpler and more reasonable.

When the seventh material baffle plate 73 moves to the seventh material discharge position (such as Fig.15 As shown in FIG. 1 , the seventh material passing holes are connected to the corresponding material outlets one by one, so that the blood collection tubes that slide out of the material outlets slide out of the seventh material passing holes again to prevent the blood collection tubes from sliding out. When the seventh material blocking plate 73 moves to the seventh material blocking position (as shown in FIG. 1 ), the seventh material blocking plate 73 moves to the seventh material blocking position (as shown in FIG. 1 ). Fig.14As shown in the figure, the seventh material passing hole is staggered at the material outlet, so that the seventh material blocking plate 73 forms a blocking effect at the material outlet, which can block the blood collection tube in the fourth material receiving channel 711 to prevent the blood collection tube from accidentally slipping out, and the structure is safer and more reasonable. Furthermore, the seventh elastic push assembly 74 and the seventh material discharge push assembly 75 are both arranged on the rotating material receiving seat 71, and the seventh elastic push assembly 74 elastically drives the seventh material blocking plate 73 to move to the seventh material blocking position, so that the seventh material blocking plate 73 can automatically reset and move to the seventh material blocking position to block the blood collection tube in the fourth material receiving channel 711. The seventh material discharge pushing assembly 75 can push the seventh material stopper plate 73 to overcome the force of the seventh elastic pushing assembly 74 and move to the seventh material discharge position. When the blood collection tube needs to be released, the seventh material discharge pushing assembly 75 pushes the seventh material stopper plate 73 to overcome the force of the seventh elastic pushing assembly 74 and move to the seventh material discharge position, so that the blood collection tube that slides out of the discharge port slides out of the seventh material passing hole again, thereby avoiding the release of the blood collection tube from sliding out, and the structure is simpler and more reasonable. In detail, in this embodiment, the material receiving mechanism 70 also includes: a linkage block 76 and a fixed seat 77, and the linkage block 76 is fixed on the seventh material stopper plate 73. The fixed seat 77 is fixed on the rotating material receiving seat 71, and the fixed seat 77 is recessed along the moving direction of the seventh material stopper plate 73 to form an installation groove. Among them, the seventh elastic pushing component 74 is arranged on the fixed seat 77 and elastically pushes on the connecting block 76, and the specific structure of the seventh elastic pushing component 74 can be selected to be an elastic pushing structure on the connecting block 76 by elastically pushing a slider sliding on the fixed seat 77 through a spring, so as to elastically drive the connecting block 76 to drive the seventh material blocking plate 73 to move to the seventh material blocking position.

[0064] Please continue reading Figure 1 3 to Fig.15 In this embodiment, the seventh material discharge pushing assembly 75 includes: a tenth linear drive 751 and a fifth push plate 752. The tenth linear drive 751 can be selected as a cylinder, but it is not limited thereto. The tenth linear drive 751 is fixed on the rotating material receiving seat 71 along the moving direction of the seventh material blocking plate 73. The fifth push plate 752 is fixed to the driving end of the tenth linear drive 751. The fifth push plate 752 is detachably pushed on the side of the linkage block 76 away from the sliding push block. When it is necessary to release the blood collection tube, the tenth linear drive 751 drives the fifth push plate 752 to push the linkage block 76 to overcome the elastic force of the seventh elastic push assembly 74, so as to drive the seventh material blocking plate 73 to move to the seventh material discharge position, so that the blood collection tube that slides out of the material outlet slides out of the seventh material passing hole again, thereby avoiding the released blood collection tube from sliding out.

[0065] See also Fig.14 and Fig.15The seventh material baffle plate 73 is provided with a plurality of limiting engaging protrusions 732 extending along a direction perpendicular to the movement direction of the seventh material baffle plate 73, and the rotating material receiving seat 71 is provided with a limiting groove 712 corresponding to the limiting engaging protrusions 732 one by one. A first blocking wall 7121 and a second blocking wall 7122 are distributed in the limiting groove 712 along the movement direction of the seventh material baffle plate 73, and the limiting engaging protrusions 732 move one by one between the first blocking wall 7121 and the second blocking wall 7122 in the corresponding limiting groove 712; when the seventh material baffle plate 73 moves to the seventh material baffle position, the limiting engaging protrusion 732 abuts against the first blocking wall 7121. Therefore, through the limiting action of the first blocking wall 7121 and the second blocking wall 7122 in the limiting groove 712, the limiting engaging protrusion 732 is limited to move between the first blocking wall 7121 and the second blocking wall 7122 in the corresponding limiting groove 712, so as to limit the moving stroke of the seventh material blocking plate 73, prevent the seventh material blocking plate 73 from excessive movement, and the structure is safer and more reasonable. Moreover, when the seventh material blocking plate 73 moves to the seventh material blocking position, the limiting engaging protrusion 732 abuts against the first blocking wall 7121, and the seventh elastic pushing assembly 74 drives the sliding pushing block to push the linkage block 76 to drive the seventh material blocking plate 73 to move to the seventh material blocking position, so that the seventh material blocking plate 73 is maintained at the seventh material blocking position in the two-way limiting of the seventh elastic pushing assembly 74 and the first blocking wall 7121.

[0066] See also Figures 13 to 15 The rotary drive mechanism 72 includes: a gear 721, a rack 722 and an eleventh linear driver 723. The gear 721 is fixedly connected to the rotary material receiving seat 71, and the axis of the gear 721 coincides with the pivot axis of the rotary material receiving seat 71; the rack 722 is arranged on the translation slide 60a and moves in the left and right directions, and the rack 722 is meshed with the gear 721. The eleventh linear driver 723 can be selected as a cylinder, but it is not limited to this. The eleventh linear driver 723 is fixed on the translation slide 60a, and the rack 722 is fixedly connected to the driving end of the eleventh linear driver 723. The rack 722 is driven to move by the eleventh linear driver 723, and then the gear 721 is driven by the rack 722 to drive the rotary material receiving seat 71 to rotate, thereby realizing the installation structure in which the rotary drive mechanism 72 drives the rotary material receiving seat 71 to rotate.

[0067] Furthermore, the rotating receiving seat 71 has a feeding position and a discharging position in the rotation direction. When the rotating receiving seat 71 rotates to the feeding position and the sixth movable receiving seat 528 moves to the third folding position, the feeding port is vertically upward, the discharging port is vertically downward, the fourth receiving channel 711 is vertically aligned with the third receiving channel 5281 directly below, and the seventh baffle plate 73 is at the seventh baffle position. When the rotating receiving seat 71 rotates to the discharging position, the feeding port is horizontally facing left, the discharging port is horizontally facing right, and the tenth linear drive 751 drives the seventh baffle plate 73 to move to the seventh discharging position.

[0068] Furthermore, the horizontal material pushing mechanism 80 includes: a twelfth linear drive 81, a movable mounting seat 82, and a push rod 83 corresponding to the fourth material receiving channel 711. The twelfth linear drive 81 can be selected as a cylinder, but it is not limited thereto. The twelfth linear drive 81 is fixed on the translation slide 60a in the left-right direction, and the movable mounting seat 82 is arranged on the translation slide 60a to move in the left-right direction. The movable mounting seat 82 is fixedly connected to the driving end of the twelfth linear drive 81 to drive the movable mounting seat 82 to move in the left-right direction through the twelfth linear drive 81. The left end of the push rod 83 is fixed on the movable mounting seat 82 in the left-right direction, and the feed port on the rotating material receiving seat 71 at the material discharging position is directly opposite to the right end of the push rod 83 in the left-right direction. The outer diameter of the push rod 83 is less than or equal to the inner diameter of the fourth material receiving channel 711. Then, when the translation slide 60a drives the material receiving mechanism 70 to move to the loading station, the eleventh linear driver 723 drives the rotating material receiving seat 71 to rotate to the discharging position. At this time, the feed port on the rotating material receiving seat 71 is opposite to the right end of the push rod 83 in the left and right direction. The twelfth linear driver 81 can be used to drive the movable mounting seat 82 to move to the right, so that the push rod 83 is inserted from the feed port of the fourth material receiving channel 711 until the blood collection tube in the fourth material receiving channel 711 is pushed into the vertical pushing mechanism 90. The structure is simpler and more reasonable.

[0069] See also Fig.13 and Fig.16The vertical pushing mechanism 90 includes: a front limit plate 91, a rear limit plate 92, a right limit plate 93, a movable bearing plate 94, a thirteenth linear drive 95, a fourteenth linear drive 96 and a lifting and pressing plate 97. The front limit plate 91 and the rear limit plate 92 are both vertically fixed on the frame 10a, and the front limit plate 91 is located at the front side of the rear limit plate 92 at a distance, and the right limit plate 93 is vertically fixedly connected between the right side of the front limit plate 91 and the right side of the rear limit plate 92, and a pressing area 98 is surrounded by the front limit plate 91, the rear limit plate 92 and the right limit plate 93, and the pressing area 98 is located on the loading station. The movable carrier plate 94 is arranged on the frame 10a to move in the left-right direction, and the movable carrier plate 94 can be moved into or out of the pressing area 98. The thirteenth linear actuator 95 can be selected as a cylinder, but it is not limited to this. The thirteenth linear actuator 95 is fixed on the frame 10a in the left-right direction, and the movable carrier plate 94 is fixedly connected to the driving end of the thirteenth linear actuator 95, so that the movable carrier plate 94 is driven to move into or out of the pressing area 98 through the thirteenth linear actuator 95. The fourteenth linear actuator 96 can be selected as a cylinder, but it is not limited to this. The fourteenth linear actuator 96 is vertically fixed on the frame 10a, and the lifting and pressing plate 97 is horizontally fixedly connected to the driving end of the fourteenth linear actuator 96, and the lifting and pressing plate 97 is located directly above the pressing area 98, so that the lifting and pressing plate 97 can be driven by the fourteenth linear actuator 96 to move vertically up and down in the pressing area 98. When the rotating receiving seat 71 rotates to the discharge position, the discharge port faces the material pressing area 98, and the vertical height position of the discharge port is higher than the movable carrier plate 94. Then, when the translation slide 60a drives the receiving mechanism 70 to move to the loading station, the movable carrier plate 94 can be moved into the material pressing area 98, and the eleventh linear driver 723 drives the rotating receiving seat 71 to rotate to the discharge position, and then the twelfth linear driver 81 drives the movable mounting seat 82 to move to the right, so that the push rod 83 is inserted from the feed port of the fourth receiving channel 711 facing it, until the blood collection tube in the fourth receiving channel 711 is pushed into the vertical pushing mechanism 90, and the blood collection tube can be pushed into the movable carrier plate 94 in the material pressing area 98, and then the thirteenth linear driver 9 The movable carrier plate 94 is driven to move out of the material pressing area 98. During the process of the movable carrier plate 94 moving out of the material pressing area 98, the blood collection tube on the movable carrier plate 94 is blocked and stays in the material pressing area 98 by the blocking effect of the right limit plate 93. When the movable carrier plate 94 is completely moved out of the material pressing area 98, the lifting and pressing plate 97 is driven by the fourteenth linear actuator 96 to move vertically downward in the material pressing area 98, so that the blood collection tube can be pushed into the packaging bag or packaging box below the material pressing area 98 by the lifting and pressing plate 97, thereby completing the bagging of the blood collection tube, and the structure is simpler and more reasonable.

[0070] See also Figure 1 and Fig.17Optionally, the blood sampling tube loading device 100 of the present invention further includes: an annular transfer drive device 400 and a plurality of automatic lifting storage devices 500, the annular transfer drive device 400 is arranged on the frame 10a, and the automatic lifting storage device 500 includes: a storage frame 11, a lifting bearing seat 12, a first elastic friction component 13 and a second elastic friction component 14, a vertically recessed receiving groove 111 is formed in the storage frame 11, and the lifting bearing seat 12 moves vertically in the receiving groove 111.

Then, the lifting bearing seat 12 is elastically rubbed against the left inner wall of the receiving groove 111 by the first elastic friction component 13, and the second elastic friction component 14 is elastically rubbed against the right inner wall of the receiving groove 111, forming an upward friction force. When there is no external force pushing the lifting bearing seat 12 downward, the lifting bearing seat 12 can be positioned in the receiving groove 111; when there is a sufficiently large external force pushing the lifting bearing seat 12 downward, the lifting bearing seat 12 can slide downward in the receiving groove 111. Furthermore, the material storage frame 11 horizontally surrounds the multi-layer folding device 200 and circulates on the frame 10a. The material storage frame 11 is transmission-connected to the annular transfer drive device 400. The annular transfer drive device 400 drives the material storage frame 11 to circulate to the lower part of the pressing area 98 to receive the vertical pushing mechanism 90 to push the blood collection tube vertically downward, so as to circulate and drive the material storage frame 11 with the packaging bag to receive and store the folded and sorted blood collection tubes. Moreover, there are several unloading stations distributed on the circular route of the circulating movement of the storage frame 11. The position of the unloading station is different from the position below the pressing area 98. When the packaging bag in the storage frame 11 is loaded with a predetermined number of blood collection tubes, it can be moved to the unloading station for unloading and removal operations.

[0071] In detail, the first elastic friction assembly 13 includes: a plurality of first friction members 131 and third elastic members 132 corresponding to the first friction members 131, the first friction members 131 are arranged on the left side of the lifting bearing seat 12 in a movable manner in the left-right direction, the third elastic member 132 is in contact between the lifting bearing seat 12 and the first friction members 131, and the third elastic member 132 constantly drives the first friction members 131 to frictionally contact the left inner wall of the receiving groove 111. Thus, the elastic pushing force of the third elastic member 132 maintains the first friction member 131 to frictionally contact the left inner wall of the receiving groove 111. The second elastic friction assembly 14 includes: a plurality of second friction members 141 and fourth elastic members 142 corresponding to the second friction members 141 one by one. The second friction members 141 are arranged on the right side of the lifting bearing seat 12 and are movable in the left-right direction. The fourth elastic member 142 is in contact between the lifting bearing seat 12 and the second friction members 141. The fourth elastic member 142 constantly drives the second friction members 141 to frictionally contact the right inner wall of the receiving groove 111. Thus, the elastic pushing force of the fourth elastic member 142 maintains the second friction members 141 to frictionally contact the left inner wall of the receiving groove 111.

[0072] Among them, the specific structure and working principle of the annular transfer drive device 400 are conventional technical means well known to technicians in this field. For example, the annular transfer drive device 400 can be selected as a motor driven annular chain to drive the storage frame 11 to move horizontally around the multi-layer folding device 200, but it is not limited to this. It is all within the protection scope of the present invention, so it will not be described in detail here.

[0073] Combined with the accompanying drawings, the working principle of the blood sampling management tube loading device 100 of the present invention is described in detail:

[0074] First, the first linear driver 29a drives the first movable material receiving seat 24a to move until it abuts against the first limit baffle 22, and the second linear driver 29b drives the fourth movable material receiving seat 24d to move until it abuts against the second limit baffle 23, and under the elastic pushing action of the first elastic support component and the second elastic support component, the first movable material receiving seat 24a and the second movable material receiving seat 24b move away from each other in the front-to-back direction, and the third movable material receiving seat 24c and the fourth movable material receiving seat 24d move away from each other in the front-to-back direction, so that the first movable material receiving seat 24a, the second movable material receiving seat 24b, the third movable material receiving seat 24c and the fourth movable material receiving seat 24d move to the first dispersed position to receive the blood collection tubes.

[0075] Then, the first linear driver 29a drives the first movable material receiving seat 24a to push the second movable material receiving seat 24b to move toward the third movable material receiving seat 24c, and the second linear driver 29b drives the fourth movable material receiving seat 24d to push the third movable material receiving seat 24c to move toward the second movable material receiving seat 24b, until the first movable material receiving seat 24a, the second movable material receiving seat 24b, the third movable material receiving seat 24c and the fourth movable material receiving seat 24d move to the first folding position, so that the blood collection tubes are folded to the first folding distance along the front-to-back direction.

[0076] Then, the third linear driver 351 drives the first push plate 352 to simultaneously push the first baffle plate 311 and the second baffle plate 321 to move to the corresponding first discharge position and the second discharge position respectively, and the fourth linear driver 361 drives the second push plate 362 to simultaneously push the third baffle plate 331 and the fourth baffle plate 341 to move to the corresponding third discharge position and the fourth discharge position respectively, so that the blood collection tubes gathered to the first gathering distance are released and fall into the second material receiving channel on the fifth movable material receiving seat 427 moved to the second dispersion position.

[0077] Then, the driving end of the fifth linear driver 424 pushes the fifth movable material receiving seat 427 located at the front side to move backward, and the driving end of the sixth linear driver 425 pushes the fifth movable material receiving seat 427 located at the rear side to move forward, until all the fifth movable material receiving seats 427 move to the second folding position, so that the blood collection tubes are folded to the second folding distance along the front-to-back direction.

[0078] Then, the seventh linear drive 4261 drives the third push plate 4262 to simultaneously push the fifth material baffle plates 4281 on all the fifth movable material receiving seats 427 to move to the fifth material discharge position, so that the blood sampling tubes gathered to the second gathering interval are released and fall into the third material receiving channel 5281 on the sixth movable material receiving seat 528 moved to the third dispersing position.

[0079] Then, the driving end of the eighth linear drive 524 pushes the sixth movable material receiving seat 528, which is the second closest to the fifth limit baffle 521, to move toward the fifth limit baffle 521, so that the distance between the two sixth movable material receiving seats 528 closest to the fifth limit baffle 521 is continuously reduced, and the second cross telescopic frame 523 can be driven to close and shorten to pull all the sixth movable material receiving seats 528 to move closer to each other, until the sixth movable material receiving seat 528 adjacent to the fifth limit baffle 521 abuts against the fifth limit baffle 521, so that all the sixth movable material receiving seats 528 move to the third folded position, and the blood collection tubes are folded to the third folded distance along the front-to-back direction.

[0080] Then, the ninth linear drive 5271 drives the fourth push plate 5272 to simultaneously push the sixth material baffle plates 5291 on all the sixth movable material receiving seats 528 to move to the sixth material discharge position, that is, to release the blood collection tubes that are folded to the third folding interval into the fourth material receiving channel 711 on the rotating material receiving seat 71 located at the feeding position.

[0081] Then, the translation drive mechanism 60b drives the translation slide 60a to drive the material receiving mechanism 70 and the blood collection tube it receives to move to the loading station, and the eleventh linear driver 723 drives the rotating material receiving seat 71 to rotate to the discharge position. At this time, the feed port on the rotating material receiving seat 71 is aligned with the right end of the push rod 83 in the left-right direction, and then the tenth linear driver 751 drives the fifth push plate 752 to push the connecting block 76 to drive the seventh baffle plate 73 to move to the seventh discharge position, so that the seventh material passing holes are aligned with the corresponding discharge ports.

[0082] Next, the twelfth linear actuator 81 drives the movable mounting seat 82 to move rightward, so that the push rod 83 is inserted from the feed port of the fourth material receiving channel 711 facing the material receiving channel until the blood collection tube in the fourth material receiving channel 711 is pushed onto the movable carrier plate 94 in the material pressing area 98, and then the thirteenth linear actuator 95 drives the movable carrier plate 94 to move out of the material pressing area 98. In the process of the movable carrier plate 94 moving out of the material pressing area 98, the right limit plate 93 blocks the movable carrier plate 94. The blood collection tube is blocked and stays in the pressing area 98. When the movable supporting plate 94 is completely moved out of the pressing area 98, the lifting and pressing plate 97 is driven by the fourteenth linear drive 96 to move vertically downward in the pressing area 98, so that the blood collection tube can be pushed by the lifting and pressing plate 97 to be pressed into the packaging bag in the storage frame 11 moved below the pressing area 98. When the blood collection tube is continuously pushed into the packaging bag in the storage frame 11, the lifting and pressing seat 12 is synchronously pushed downward to make more space for receiving the blood collection tube.

[0083] When the packaging bag in the material storage frame 11 moved to the bottom of the material pressing area 98 is loaded with a predetermined number of blood collection tubes, the circular transfer drive device 400 can move the material storage frame 11 to the unloading station to take out the packaging bag and the packed blood collection tubes. Then the lifting bearing seat 12 is moved upward to the upper end of the receiving groove 111 and a new packaging bag is put on it, and then it is circulated and moved to the bottom of the material pressing area 98 to receive the blood collection tubes, so as to circulate and package the collected and sorted blood collection tubes.

[0084] In summary, the blood collection tube loading equipment 100 of the present invention realizes the mechanical and automatic reception of the blood collection tubes and then retracts them to the required third retraction interval and completes the loading. It has a simple and compact structure, and replaces the manual retraction and sorting of the blood collection tubes for loading. The operation speed is greatly improved, the time spent on the operation is greatly reduced, the efficiency is also greatly improved, and the labor force can be reduced, thereby improving the efficiency of sorting, gathering and packaging of the blood collection tubes, avoiding human contact, and preventing the risk of contamination of the blood collection tubes, which can better meet the needs of efficient, clean and safe sorting and packaging.

[0085] The present invention is described above in conjunction with the embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations based on the essence of the present invention.
