Description

Technical Field

[0001] The invention relates to the technical field of blood collection tube arrangement and packaging, and in particular to a multi-layer folding device. Background Art

[0002] Blood collection tubes are disposable, negative pressure vacuum glass tubes that can achieve quantitative blood collection. They are used as medical equipment for collecting blood samples or infusing fluids. Blood from patients is collected in blood collection tubes, making it easier for doctors to conduct various examinations and treatments.

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 4271, and the material in the second material receiving channel 4271 can fall downward from the fifth material passing hole 42811. When the fifth material blocking plate 4281 moves to the fifth material blocking position, the fifth material passing hole 42811 is misaligned at the lower end of the second material receiving channel 4271. At this time, the fifth material blocking plate 4281 blocks the lower end of the second material receiving channel 4271 to block the material in the second material receiving channel 4271. Furthermore, the fifth elastic pushing component 4282 is arranged on the fifth movable material receiving seat 427, and the fifth elastic pushing component 4282 elastically drives the fifth material blocking plate 4281 to move to the fifth material blocking position. In detail, in this embodiment, the specific structure of the fifth elastic pushing component 4282 can be selected as an elastic pushing structure that pushes a slider against the fifth material blocking plate 4281 through a spring elastic push, so as to realize elastically driving the fifth material blocking plate 4281 to move to the fifth material blocking position, so that the fifth material blocking plate 4281 can automatically reset and move to the fifth material blocking 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.

[0087] 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 materials received by the second receiving channel 4271 on the corresponding fifth movable receiving seat 427, and the structure is simpler and more reasonable.

[0088] 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, which are all within the protection scope of the present invention, so it 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. Thus, 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 the receiving materials. The inner diameter of the third material receiving channel 5281 is equal to the inner diameter of the second material receiving channel 4271, and the number of the third material receiving channels 5281 is equal to the number of the second material receiving channels 4271. 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 along 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. The sixth material blocking assembly 529 is arranged at the bottom of the sixth movable material receiving seat 528 in a one-to-one correspondence, so as to block the materials received by all the third material receiving channels 5281 on the sixth movable material receiving seat 528 from falling through the sixth material blocking assembly 529. Furthermore, the fourth material discharge push 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 4271 directly below, so that the materials released from the second material receiving channels 4271 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 materials received by all the third material receiving channels 5281 on the corresponding sixth movable material receiving seats 528. Then, the driving end of the eighth linear actuator 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 actuator 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. Move in the direction away from the fifth limit baffle 521, 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 material.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 material received by the third material receiving channel 5281 on the corresponding sixth movable material receiving seat 528.

When the sixth material blocking plate 5291 moves to the sixth material blocking 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 blocking plate 5291 blocks the lower end of the third material receiving channel 5281 to block the material in the third material receiving channel 5281. The sixth elastic pushing component 5292 is arranged on the sixth movable material receiving seat 528, and the sixth elastic pushing component 5292 elastically drives the sixth material blocking plate 5291 to move to the sixth material blocking position. The specific structure of the sixth elastic pushing component 5292 can be selected as an elastic pushing structure that pushes a slider against the sixth material blocking plate 5291 through a spring elastic push, so as to realize elastically driving the sixth material blocking plate 5291 to move to the sixth material blocking position, so that the sixth material blocking plate 5291 can automatically reset and move to the sixth material blocking position, and the structure is simpler and more reasonable.

The ninth linear drive 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 drive 5271. When the sixth movable receiving seat 528 moves to the third folding 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 folding position to release the materials received by the third receiving channel 5281 on the corresponding sixth movable receiving seat 528, and the structure is simpler and more reasonable.

[0100] Then, the first linear drive 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 drive 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 material is folded to the first folding distance along the front-to-back direction.

Then, the material receiving and gathering mechanism 20 receives the material and gathers it to the first gathering distance in the front-to-back direction, and then releases the material gathered to the first gathering distance to the transfer gathering mechanism 40, and then the transfer gathering mechanism 40 receives the material released by the material receiving and gathering mechanism 20 and gathers it to the second gathering distance in the front-to-back direction, and then releases the material gathered to the second gathering distance to the material discharging and gathering mechanism 50, and then the material discharging and gathering mechanism 50 receives the material released by the transfer gathering mechanism 40 and gathers it to the third gathering distance in the left-right direction, and then releases the material for unloading.
