Installed at both ends of the rotating shaft 11, the fixed ends of the first drive cylinder 12 are hinged to the frame 1, and the output ends of the first drive cylinder 12 are hinged to the corresponding drive blocks 13 respectively. A plurality of placement slots 14 corresponding to the push rods 6 are provided on the flip frame 10, and an opening 15 is provided on the flip frame 10; further, the first drive mechanism 7 is preferably a mechanical slide, and the first drive mechanism 7 can also be a hydraulic cylinder or a pneumatic cylinder; the second drive mechanism 9 can be a hydraulic cylinder, a pneumatic cylinder, a linear motor or a mechanical slide, preferably a transmission belt and a drive motor The machine has a feeding box 2 on which a roller is rotatably mounted, a conveyor belt is sleeved on the roller, the conveyor belt is fixedly connected to the second feed seat 8, and the output end of the drive motor is connected to one of the rollers through a transmission belt; the left and right sliding of the first feed seat 4 is achieved by the first drive mechanism 7, and the up and down sliding of the second feed seat 8 is achieved by the second drive mechanism 9. The glue dispensing component extends from the opening 15 and contacts the blood collection tube in the corresponding placement groove 14. During the process of the push rod 6 pushing the blood collection tube, the glue dispensing component applies the colloid linearly on the blood collection tube.

[0026] Specifically, it also includes an auxiliary conveying mechanism, which includes a conveyor 16 and a mold frame 17 placed on the conveyor 16, and the mold frame 17 is provided with placement holes 18 arranged corresponding to the placement slots 14; further, the conveyor 16 can adopt a belt conveyor 16 or a chain conveyor 16, preferably a belt conveyor 16; the end of the conveyor 16 is provided with a positioning baffle, and when the end of the mold frame 17 contacts the positioning baffle, the placement hole 18 and the placement slot 14 are aligned; in the initial state, the mold is placed on the positioning baffle of the conveyor 16. When the blood collection tube is coated with glue and turned 90 degrees following the turning frame 10, under the action of gravity, the blood collection tube falls into the placement hole 18 on the mold frame 17, and the mold frame 17 is conveyed to the next labeling processing equipment through the conveying mechanism; there is no need to manually transfer the blood collection tubes, and at the same time, the blood collection tubes are ensured to be loaded side by side, which is convenient for the rear labeling equipment to label the blood collection tubes.

[0027] Specifically, it also includes a limit assembly, which includes a limit plate 19, two groups of guide rods 20, a first spring 21, a first slope block 22, a second slope block 23 and a second drive cylinder 24. The guide rod 20 is fixedly mounted on the limit plate 19, and the guide rod 20 can be slid up and down on the turning frame 10. The limit plate 19 is located at one end of the turning frame 10 away from the feeding box 2, the first slope block 22 is fixedly mounted on the bottom of the guide rod 20, the first spring 21 is sleeved on the two groups of guide rods 20, the second drive cylinder 24 is fixedly mounted on the frame 1, and the second slope block 23 is fixedly mounted on the output end of the second drive cylinder 24; further, one end of the first spring 21 is in close contact with the first slope block 22, and the other end of the first spring 21 is in close contact with the turning frame 1 0 bottom; after the blood collection tube is located at the turning frame 10, the limit plate 19 limits the turning frame 10 to prevent the blood collection tube from detaching from the turning frame 10 when the turning frame 10 is turned over. When the turning frame 10 is turned to the vertical state, the output end of the second driving cylinder 24 is shortened, the second slope block 23 moves up and contacts the first slope block 22, and the slopes on the first slope block 22 and the second slope block 23 are in close contact. At this time, under the pushing of the second slope block 23, the first slope block 22 pushes the guide rod 20 to move, and the limit plate 19 is separated from the turning frame 10. After the limit plate 19 is separated from the limit on the blood collection tube, the blood collection tube falls freely under the action of gravity; thereafter, the second driving cylinder 24 is reset, and under the action of the first spring 21, the limit plate 19 is reset.

[0028] Specifically, the glue dispensing assembly includes a glue supply tube 25, a glue dispensing head 26 and a second spring 27. The glue dispensing head 26 is inserted into the output end of the glue supply tube 25, and the second spring 27 is sleeved on the glue dispensing head 26. The glue dispensing head 26 can be slid up and down on the second feed seat 8; further, one end of the second spring 27 is fixedly connected to the second feed seat 8, and the other end of the second spring 27 is fixedly connected to the glue dispensing head 26; the glue dispensing head 26 and the glue supply tube 25 are connected in a socket connection, and a sealing ring is provided between the glue dispensing head 26 and the glue supply tube 25; the glue dispensing head 26 and the glue supply tube 25 are connected in a socket connection. When the glue dispensing operation of the blood collection tube is performed, the glue dispensing head 26 and the blood collection tube are in elastic contact under the action of the second spring 27, avoiding excessive close contact between the glue dispensing head 26 and the blood collection tube, which affects the blood collection tube being pushed into the placement slot 14, and at the same time preventing the glue dispensing head 26 from scratching the blood collection tube.

[0029] Specifically, a coating brush 28 is fixedly installed on the conveyor 16; the conveyor 16 transports the mold frame 17, and the coating brush 28 contacts the outer wall of the blood collection tube. Under the action of the coating brush 28, the blood collection tube rotates during the transportation process, and the coating brush 28 evenly coats the colloid on the outer wall of the blood collection tube, thereby improving the uniformity of the colloid coating on the outer wall of the blood collection tube.

[0030] Specifically, a loading platform 29 is provided on the frame 1; the blood collection tubes can be placed on the loading platform 29 to wait for materials, thereby improving the convenience of loading the blood collection tubes into the upper material box 2.

[0031] Specifically, the tops of the partition plates 3 are staggered in height; further, the partition plates 3 are evenly distributed in parallel in the loading box 2; by staggered distribution of the tops of the partition plates 3, the blood collection tubes can be staggered and spaced apart from each other, so that the blood collection tubes can fall more smoothly between two groups of adjacent partition plates 3.

[0032] Specifically, a horizontal in-position switch 30 and a vertical in-position switch 31 are installed on the frame 1; further, the horizontal in-position switch 30, the vertical in-position switch 31, the first drive cylinder 12, and the second drive cylinder 24 are all electrically connected to the external PLC control system; through the setting of the horizontal in-position switch 30 and the vertical in-position switch 31, the flipping state of the flip frame 10 can be sensed. After the flip frame 10 is flipped into position, the external PLC system receives the signal and responds to control the start and stop of the first drive cylinder 12 and the second drive cylinder 24, thereby realizing automatic control and further reducing the amount of manual operation.

[0033] Specifically, the loading box 2 is provided with a through opening communicating with the interior of the loading box 2, and a blocking door 32 is detachably installed at the through opening; when the blood collection tubes are stuck in the loading box 2, the blood collection tubes in the loading box 2 can be sorted out by removing the blocking door 32, which is more convenient and quick.

[0034] When in use, the blood collection tube and the partition plate 3 are placed in the loading box 2 in the same direction, with the blood collection tube port facing the side of the push rod 6, and the blood collection tubes are stacked side by side between two sets of adjacent partition plates 3. The first driving mechanism 7 drives the first feed seat 4 to feed, and the push frame 5 drives the push rod 6 to insert into the corresponding blood collection tube. Under the action of the push rod 6, the blood collection tube moves to the flip frame 10. At the same time, the second feed seat 8 feeds, the glue dispensing component moves down and contacts the outer wall of the blood collection tube, and the colloid flows out from the glue dispensing component. As the blood collection tube is completely fed into the placement groove 14 at the flip frame 10, the colloid is coated on the blood collection tube, and the push rod 6 and the glue dispensing mechanism are reset. At this time, the first The driving cylinder 12 is actuated, and after being transmitted by the driving block 13 and the rotating shaft 11, the turning frame 10 turns 90 degrees, the output end of the second driving cylinder 24 is shortened, the second slope block 23 moves up and contacts the first slope block 22, and the slopes on the first slope block 22 and the second slope block 23 are in close contact. At this time, under the pushing of the second slope block 23, the first slope block 22 pushes the guide rod 20 to move, and the limit plate 19 is separated from the turning frame 10. After the limit plate 19 is separated from the limit on the blood collection tube, the blood collection tube falls freely under the action of gravity, and the blood collection tube falls into the placement hole 18 on the mold frame 17. The mold frame 17 is conveyed to the next labeling processing equipment through the conveyor 16.
