[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0027] Referring to Figures 1-3 , an embodiment provided by the present invention: A flatting device for the core of a blood collection needle for processing, including a bottom plate 1. A limiting groove 2 is opened in the middle of the bottom plate 1. Threaded blocks 3 are slidably connected to the front and back inside the limiting groove 2. A clamping plate 6 is fixedly connected to the upper part of the threaded block 3. A plurality of grooves are opened on the opposite sides of the two clamping plates 6. The number of grooves corresponds to the core body 7 of the blood collection needle. A driving component is arranged on the front side of the bottom plate 1. A plurality of core bodies 7 of the blood collection needle are evenly arranged in the middle of the bottom plate 1. The driving component includes a motor 4 and a bidirectional threaded rod 5. The motor 4 is fixedly connected to the front side of the bottom plate 1. The bidirectional threaded rod 5 is fixedly connected to the output end of the motor 4. The bidirectional threaded rod 5 is threadedly connected to the inside of the threaded block 3. The bidirectional threaded rod 5 penetrates through the bottom plate 1.
[0028] Place the core body 7 of the blood collection needle on the upper part of the bottom plate 1, so that the core body 7 of the blood collection needle is located in the middle of the side where the front and back grooves are close to each other. Then control the start of the motor 4 to make the motor 4 run and drive the bidirectional threaded rod 5 to rotate. The bidirectional threaded rod 5 drives the threaded block 3 to move relatively inside the limiting groove 2. The limiting groove 2 limits the threaded block 3. The threaded block 3 drives the clamping plate 6 to move relatively, so that the grooves on the opposite sides of the two clamping plates 6 clamp the core body 7 of the blood collection needle.
[0029] Referring to Figures 1-3 , mounting plates 8 are fixedly connected to the left and right sides of the upper part of the bottom plate 1. Sliding grooves 9 are opened on the opposite sides of the two mounting plates 8. A connecting block 11 is slidably connected to the inner side of the sliding groove 9. Cylinders 10 are fixedly connected to the left and right sides of the middle part of the bottom plate 1. The output end of the cylinder 10 is fixedly connected to the connecting block 11. A flattening component is arranged on the opposite sides of the two connecting blocks 11. The flattening component includes a flattening plate 12 and a flattening groove 13. The flattening plate 12 is fixedly connected to the opposite sides of the two connecting blocks 11. The flattening grooves 13 are evenly opened inside the flattening plate 12. The number of flattening grooves 13 corresponds to the core body 7 of the blood collection needle.
[0030] Control the start of the cylinder 10 to make the cylinder 10 run and drive the connecting block 11 to slide inside the sliding groove 9. The sliding groove 9 limits the connecting block 11. The connecting block 11 drives the flattening plate 12 to move. The flattening plate 12 drives the flattening groove 13 to slide outside the core body 7 of the blood collection needle to flatten the core body 7 of the blood collection needle.
[0031] Working principle: When it is necessary to fix the blood collection needle core, place the blood collection needle core body 7 on the upper part of the bottom plate 1, and then control the start of the motor 4 to make the motor 4 operate to drive the bidirectional threaded rod 5 to rotate. The bidirectional threaded rod 5 drives the threaded block 3 to move relatively, and the threaded block 3 drives the clamping plate 6 to move relatively, so that the grooves on the opposite sides of the two clamping plates 6 clamp the blood collection needle core body 7. In this way, it is realized that the leveling device can clamp and fix the blood collection needle core, preventing the blood collection needle core from sliding during the leveling process and affecting the leveling efficiency. When it is necessary to level the blood collection needle core, control the start of the cylinder 10 to make the cylinder 10 operate to drive the connecting block 11 to move. The connecting block 11 drives the leveling plate 12 to move, and the leveling plate 12 drives the leveling groove 13 to slide on the outside of the blood collection needle core body 7 to level the blood collection needle core body 7. In this way, it is realized that the leveling device can level multiple blood collection needle cores at the same time, improving the processing efficiency of the blood collection needle core.
[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
