There are multiple docking tubes 25 and multiple docking tubes 25 are installed in the first circulating conveying component 34 at equal intervals. The first circulating conveying component 34 includes a first slide rail 47 and a first mounting seat 48. The first slide rail 47 is longitudinally installed on the table 1 by bolts. A first mounting seat 48 that translates on the first slide rail 47 is clamped on the first slide rail 47.

The bagging mechanism 26 is moved to dock with the bagging mechanism 26, which clamps the bag body. The bagging mechanism 26 is provided with an opening assembly 35 on the upper and lower sides. The bag body is opened by the opening assembly 35, and the docking tube 25 is extended into the bag body at the same time. The docking tube 25 is extended through the first clamping arm 33, and the first clamping arm 33 is loosened at the same time. The wound blood collection needle is placed in the bag body, and the first clamping arm 33 is retracted and withdraws from the bag body through the docking tube 25. The bagging mechanism 26 is provided with a second circulating conveying assembly 42. The structure of the second circulating conveying assembly 42 is consistent with that of the first circulating conveying assembly 34. A sealing mechanism 27 is provided on one side of the end of the second circulating conveying assembly 42. The second circulating conveying assembly 42 clamps the bagging mechanism 26 holding the bag body and conveys it to the opposite side of the sealing mechanism 27.The bag body and bag opening are heat-sealed by pressing down the seal; The automatic feeding mechanism 2 includes a feeding conveying track 3, a spacing component 5 and a horizontal placement component 14, wherein the blood collection needles are transported side by side on the feeding conveying track 3, and the blood collection needles are transported on the feeding conveying track 3. A spacing component 5 is arranged at the end of the feeding conveying track 3, and the blood collection needles are separated by the spacing component 5, so that only one blood collection needle is transported to the end of the feeding conveying track 3. A horizontal placement component 14 for converting a vertical blood collection needle into a horizontally placed blood collection needle is docked at the end of the feeding conveying track 3, and the clamping component 32 clamps the horizontal blood collection needle and places it on the winding mechanism 18. When working, the blood collection needle is transported to the end of the feeding conveying track 3 through the feeding conveying track 3, and the blood collection needle is clamped and placed horizontally through the horizontal placement component 14, and then the clamping component 32 clamps both ends of the blood collection needle, and one end of the blood collection needle is clamped through the winding mechanism 18, and the blood collection needle is wound through the winding mechanism 18; The opening assembly 35 includes two upper and lower groups of negative pressure suction heads 36. The two groups of negative pressure suction heads 36 are lifted and lowered. The two groups of negative pressure suction heads 36 are installed on the suction head lifting rod by bolt fastening. A No. 4 air cylinder is installed between the suction head lifting rod at the bottom and the table 1 by bolt fastening. A translation rod 49 is arranged above the suction head lifting rod at the top. The translation rod 49 translates left and right above the table 1. A No. 5 air cylinder is installed between the translation rod 49 and the suction head lifting rod at the bottom by bolt fastening. The lifting of the suction head lifting rod is realized by two groups of No. 4 air cylinders and No. 5 air cylinders, so that the upper and lower groups of negative pressure suction heads 36 are closed and separated; the two groups of negative pressure suction heads 36 are closed and separated. There are multiple groups of opening plates 37 arranged in between, and each group of opening plates 37 is arranged up and down, and compression plates 38 are installed on the upper and lower sides of each group of opening plates 37. When the opening plates 37 compress the bag body, it is prevented that the bag body and the opening plates 37 are separated when the blood collection needle is inserted. When working, the bag body is transported between the two groups of negative pressure suction heads 36, and the negative pressure suction heads 36 adsorb the bag body. At the same time, the two groups of negative pressure suction heads 36 are opened, so that the bag body is initially opened, and then the opening plates 37 are extended into the bag body, and then the opening plates 37 are moved away from each other, so that the bag body is opened by the opening plates 37, and then the docking tube 25 is extended into the bag body, and at the same time, the docking tube 25 inserts the wound blood collection needle into the bag body.

[0033] A plurality of groups of opening plates 37 are arranged side by side, and the upper and lower opening plates 37 of each group of opening plates 37 are respectively mounted on two mounting rods 39, and a spacing adjustment component 40 is arranged between the two ends of the two mounting rods 39. The spacing adjustment component 40 is a vertical guide rod, and there are two guide rods, and the two guide rods pass through the two mounting rods 39. The two mounting rods 39 are lifted and lowered on the guide rods. A No. 6 cylinder is installed between the guide rods and each mounting rod 39 by bolts, and the mounting rod 39 is moved up and down on the guide rod by the extension and contraction of the No. 6 cylinder. Two fixing rods are fixed between the two guide rods by bolt fastening, and the two fixing rods are respectively located at the upper and lower sides of the mounting rod 39, and an L-shaped frame is fixed on the fixing rod, and a horizontal installation is fixed at the end of the L-shaped frame by welding. The clamping plate 38 is arranged on the bag body. When the two opening plates 37 are separated, the edge of the bag mouth is clamped by the opening plate 37 and the clamping plate 38. In this way, when the docking tube 25 is inserted into the bag body, the bag body is prevented from being separated from the opening plate 37 due to the insertion of the docking tube 25. A first translation assembly 41 is arranged on the two mounting rods 39. The first translation assembly 41 is used to extend multiple groups of opening plates 37 into the bag body, that is, a first guide rail is fixed on the table top 1 by bolt fastening, and a first sliding seat moving on the first guide rail is clamped on the first guide rail. The first sliding seat is fixed to the bottom of the guide rod by bolt fastening, and a No. 7 cylinder is installed between the first sliding seat and the table top 1 by bolt fastening, and the left and right translation of the opening plate 37 is realized by the extension and contraction of the No. 7 cylinder.

[0034] The upper and lower opening plates 37 of each group of opening plates 37 are offset from each other. When the two mounting rods 39 are closed, the end of each group of opening plates 37 away from the mounting rods 39 is on the same plane, and the end of the opening plates 37 close to the mounting rods 39 is an inclined section, which makes it easy for each group of opening plates 37 to extend into the bag body. When the ends of the two opening plates 37 extending into the bag opening are located on the same flat plate, the width of the bag opening required for the opening plates 37 to extend into the bag body becomes smaller, which makes it easy for the opening plates 37 to extend into the bag body, and avoids the opening plates 37 from being lifted up and extended into the bag body, so that the opening plates 37 are against the edge of the bag body and cannot open the bag body.

[0035] Each opening plate 37 located on the upper mounting rod 39 is divided into two parts, and an expansion component 43 is arranged between the two opening plates 37. The expansion component is a finger cylinder, which is mounted on the mounting rod 39 by bolts. The clamping arm of the finger cylinder is fixed to the opening plate 37 by welding. The opening plate 37 located on the lower mounting rod 39 is located between the clamping arms of the finger cylinder. The opening plate 37 is expanded to both sides by the expansion component 43, and the bag body is opened. When working, the mounting rod 39 is closed, so that the opening plates 37 are located at the same level. On the surface, the opening component 35 opens the bag body, and one end of the opening plate 37 is extended into the opened bag mouth through the first translation component 41, and then the two mounting rods 39 are separated, so that the bag body is opened, and then the docking sleeve 25 is extended into the bag body, and at the same time, the docking sleeve 25 leaves the blood collection needle in the bag body, and then the docking sleeve 25 withdraws from the bag body, and the mounting rod 39 is closed, and finally the expansion component is opened, and the opening plate 37 moves to both sides, so that the bag mouth of the bag body is closed, and finally the second circulating conveying component 42 clamps the bag body, the mounting rod 39 moves to the left, and the opening rod withdraws from the bag body.

[0036] Each feeding conveying track 3 is composed of two feeding rods 4 arranged side by side, and the interval between the two feeding rods 4 is used to convey the blood collection needle. The blood collection needle is provided with a puncture needle with one end larger than the interval of the feeding rod 4. The puncture needle slides between the two feeding rods 4, and the right end of the feeding rod 4 is tilted downward, so that the feeding rod 4 conveys the blood collection needle to the right; a spacing assembly 5 is arranged above the end of the feeding rod 4, and the spacing assembly 5 includes a rotating shaft 6 and two fan-shaped partitions 7. The two fan-shaped plates are mounted on the rotating shaft 6 by welding, and the two fan-shaped partitions 7 rotate coaxially. The rotating shaft 6 is mounted on the feeding rod 4 through bearings and bearing seats, so that the rotating shaft 6 rotates above the two feeding rods 4, and the notches of the two fan-shaped partitions 7 are staggered with each other. The notches of the fan-shaped partitions 7 are for the blood collection needle to pass through. The rotation of the rotating shaft 6 ensures that only one blood collection needle passes through the spacing assembly 5, and a return spring 8 is installed between the rotating shaft 6 and the bearing seat by bolt fastening, and the return spring 8 is used to realize The rotating shaft 6 returns to its original position, and a multi-sided groove 9 is opened on the right end of the rotating shaft 6. A multi-sided rod 10 that cooperates with the outer wall of the multi-sided groove 9 is embedded in the multi-sided groove 9. When the multi-sided rod 10 rotates, the rotating shaft 6 also rotates accordingly, and the multi-sided rod 10 slides in the multi-sided groove 9. A butt plate 11 is installed at the end of the multi-sided rod 10 away from the rotating shaft 6 (that is, on the right end surface of the multi-sided rod 10), and a spiral bevel groove 12 is opened on the back of the butt plate 11 (that is, on the left end surface of the butt plate 11). A limiting rod 13 extending into the spiral bevel groove 12 is fixed on the outer wall of the bearing seat by welding. When the abutment plate 11 is squeezed and moves to the left, the limiting rod 13 abuts against the spiral bevel groove 12 of the abutment plate 11. Thus, when the abutment plate 11 moves to the left, the abutment plate 11 also rotates. Since the abutment plate 11 is fixed to the polygonal rod 10 and the polygonal rod 10 is extended and retracted in the polygonal groove 9, the abutment plate 11 drives the rotating shaft 6 to rotate.The horizontal placement component 14 includes a second clamping arm 15 that can be translated. The second clamping arm 15 is installed on the second translation component 53 to translate left and right. The second translation component 53 includes a second translation guide rail and a second sliding seat. The second translation guide rail is installed above the table 1 by bolt fastening. The bottom of the second translation guide rail is suspended. A second sliding seat that slides on the second translation guide rail is installed on the second translation guide rail. An No. 8 cylinder is installed between the second sliding seat and the second translation guide rail by bolt fastening. The No. 8 cylinder is used to realize the translation of the second sliding seat on the second translation guide rail. A flat plate is fixed between the two second sliding seats by bolt fastening. Multiple second clamping arms 15 are fixed by screws. The bolt is installed on the flat plate, and the second clamping arm 15 is arranged horizontally. The second clamping arm 15 is docked with the end of the feeding rod 4. When the second clamping arm 15 is docked with the feeding rod 4, the second clamping arm 15 presses the left end of the push rod (the second clamping arm 15 is the finger cylinder), and the rotating shaft 6 rotates 90°. A rubber belt 16 that can be lifted and lowered is arranged on the end of the table 1 close to the feeding rod 4. The two ends of the rubber belt 16 are fixed to the piston rod of the No. 9 cylinder by bolts. The cylinder body of the No. 9 cylinder is fixed to the left end face of the second translation guide rail by bolts. The lifting and lowering of the rubber belt 16 is realized by the No. 9 cylinder. When the second clamping arm 15 is docked with the end of the feeding rod 4, the rubber belt 16 descends. When the second clamping arm 15 is away from When the feeding rod 4 is being fed, the rubber belt 16 rises to block the end of the feeding rod 4, thus preventing the lancet from falling off the feeding rod 4 due to a malfunction of the spacing component 5; two slot plates 17 are installed on the table 1 and the two slot plates 17 are arranged opposite to each other on the left and right, and multiple slots are opened on the slot plate 17 to insert one end of the lancet, and the second clamping arm 15 clamps one end of the bottle stopper puncture needle and moves it to the right, placing the lancet in the slot of the slot plate 17, and a No. 4 cylinder is installed between the slot plate 17 and the table 1 on the side of the winding mechanism 18 by bolt fastening, and the No. 4 cylinder is used to realize the translation of the slot plate 17, and the spacing between the two slot plates 17 is increased, and the slot is smaller than the needle head and the bottle stopper puncture head. When the slot plate 17 on the right side moves to the right, the slot plate 17 on the left side does not move, and the hose part of the blood collection needle is tightened; when processing, the second clamp arm 15 moves to the left, and when the second clamp arm 15 presses the plate 11, the plate 11 moves to the left, and when the second clamp arm 15 docks with the end of the feeding rod 4, the shaft 6 rotates 90°, so that the notch of the fan-shaped partition plate 7 on the right side is located directly below, so that the blood collection needle between the two fan-shaped partition plates 7 slides to the end of the feeding rod 4, and the second clamp arm 15 tries to clamp it. When the second clamp arm 15 needs to move to the right, the rubber belt 16 descends to make way for the blood collection needle to move to the right, and the second clamp arm 15 places the blood collection needle on the notch of the slot plate 17. ;

[0037] The winding mechanism 18 includes a winding rod 19, a movable clamping arm 23 and a lifting clamping arm 24. The plurality of winding rods 19 are rotatably mounted on the table 1 through bearings. The bottom of the winding rod 19 is connected to the output shaft of the motor by welding.
