[0001] The utility model relates to the technical field of bag mouth heat sealing, in particular to a bag mouth heat sealing device for blood collection needle packaging. Background Technique

[0002] A blood collection needle is a medical device specifically used for collecting blood samples. It is usually made of metal and has a sharp needle tip for puncturing the skin and entering the blood vessel. Blood collection needles should generally be placed in a dry, clean, and pollution-free environment. Special blood collection needle storage boxes or bags can be used for storage to prevent the blood collection needle from being contaminated by the outside world. To ensure the sealing of the packaging bag storing the blood collection needle, a bag mouth sealing device is usually used to seal its bag mouth.

[0003] The heat sealing process of blood collection needle packaging is usually completed by using special heat sealing equipment. These devices generate high temperatures to heat and fuse the bag mouth of the packaging material together to form a sealed package. In this process, it is necessary to strictly control the heating temperature and time to ensure the quality and reliability of the seal. In addition, it is also necessary to ensure that the packaging material itself has good heat sealing performance and can withstand high temperatures and pressures.

[0004] However, during general heat sealing, it is usually necessary to manually hold the packaging bag to ensure its stability during the heat sealing process. But manually holding the packaging bag exposes the hand near the heat sealing equipment and is prone to high-temperature burns. Especially when heat sealing operations need to be carried out frequently or for a long time, the skin of the staff's hand will be damaged due to contact with high temperatures, causing pain, blisters, or even burns. Therefore, a bag mouth heat sealing device for blood collection needle packaging is proposed to solve the above problems. Content of the Utility Model

Specific embodiments

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0032] Refer to Figure 1 And Figure 2, An embodiment provided by the present utility model: A bag mouth heat sealing device for blood collection needle packaging, including a box body 1. The inner bottom wall of the box body 1 is fixedly connected with a slide rail 4. The outer wall of the slide rail 4 is slidably connected with a sliding box 5. Both sides of the inner wall of the sliding box 5 are fixedly connected with a first slide bar 7. Both sides of the outer wall of the first slide bar 7 are slidably connected with a clamping plate 8. One side of the outer wall of the clamping plate 8 is fixedly connected with a push plate 9. The outer wall of the push plate 9 is slidably connected inside the sliding box 5. Both sides of the inner wall of the box body 1 are fixedly connected with a wedge-shaped block 11. The outer wall of the push plate 9 is in contact with the outer wall of the wedge-shaped block 11. A spring 10 is sleeved on the outer wall of the first slide bar 7. Both ends of the spring 10 are fixedly connected to the outer side walls of the two clamping plates 8. A first cylinder 6 is fixedly connected inside the box body 1. The output end of the first cylinder 6 is fixedly connected to the outer wall of the sliding box 5;

[0033] Specifically, during the heat sealing operation, the blood collection needle packaging bag to be heat sealed can be put in from the first placement opening 2 or the second placement opening 3, so that it falls into the inside of the sliding box 5. Then, the first cylinder 6 drives the sliding box 5 to slide on the outer wall of the slide rail 4 to the middle position of the box body 1. When the sliding box 5 moves to the middle of the box body 1, the two push plates 9 will contract inward due to the restriction of the wedge-shaped blocks 11 on the inner wall of the box body 1, thereby pushing the two clamping plates 8 to slide towards the center on the first slide bar 7. Furthermore, the bag mouth is clamped by the two clamping plates 8 and heat sealed. At the same time, after the sliding box 5 slides to both sides of the box body 1, the push plate 9 will lose the restriction of the wedge-shaped block 11 and expand to both sides under the action of the spring 10, so as to facilitate the taking out of the packaging bag. Such a design makes the heat sealing process more efficient and automated, and at the same time facilitates the putting in and taking out of the packaging bag, improving the production efficiency and safety.

[0034] Refer to Figure 1 And Figure 3 , A placement component is arranged inside the box body 1. The placement component includes a first placement opening 2 and a second placement opening 3. The first placement opening 2 is opened on one side inside the box body 1, and the second placement opening 3 is opened on the other side inside the box body 1;

[0035] Specifically, setting the first placement opening 2 and the second placement opening 3 on the box body 1 can effectively cooperate with the clamping mechanisms on both sides inside the sliding box 5, thereby realizing feeding and taking out at the same time, and improving the heat sealing rate of the blood collection needle packaging bag mouth.

[0036] Refer to Figure 3 And Figure 4, a cylinder two 15 is fixedly connected to the inner top wall of the box body 1. The output end of the cylinder two 15 is fixedly connected to a rack 16. A rotating shaft 17 is rotatably connected to the inner top wall of the box body 1. A gear 18 is rotatably connected to one side of the outer wall of the rotating shaft 17. The outer wall of the gear 18 meshes with the outer wall of the rack 16. A transmission rod two 20 is fixedly connected to one side of the outer wall of the rotating shaft 17. Two symmetrically arranged slide bars two 12 are fixedly connected to the inside of the box body 1. Transmission rods one 19 are rotatably connected to both sides of the transmission rod two 20. Slide blocks 13 are symmetrically arranged and slidably connected to the outer walls of the slide bars two 12. One side of the transmission rod one 19 is rotatably connected to the top of the slide block 13. A heat seal strip 14 is fixedly connected to the bottom of the slide block 13;

[0037] Specifically, when performing the heat sealing operation, the cylinder two 15 will push the rack 16 to move. The rack 16 will then drive the gear 18 to rotate. The rotation of the gear 18 will drive the rotating shaft 17 to rotate together, so that the transmission rod two 20 will also rotate accordingly. The transmission rod two 20 will synchronously drive the transmission rods one 19 on both sides, and the transmission rods one 19 will synchronously drive the slide blocks 13 on both sides. In this way, the slide blocks 13 on both sides will drive the heat seal strip 14 to clamp towards the center, and perform heat sealing on the bag mouth transported to its center position. Such a design makes the heat sealing process more accurate and efficient, ensuring that the bag mouth can be evenly and tightly sealed, improving the quality and sealing performance of the product.

[0038] Working principle: When performing heat sealing, the blood collection needle packaging bag to be heat-sealed can be put in from the placing opening one 2 or the placing opening two 3, so that the packaging bag falls into the sliding box 5. Then, the cylinder one 6 pushes the sliding box 5, so that the sliding box 5 slides on the outer wall of the slide rail 4 to the middle of the box body 1. When the sliding box 5 enters the middle of the box body 1, the two push plates 9 will contract inward due to the restriction of the wedge-shaped blocks 11 on the inner wall of the box body 1, thereby pushing the two clamping plates 8 to slide towards the center on the slide bar one 7, so that the bag mouth is clamped by the two clamping plates 8 for heat sealing. At the same time, after the sliding box 5 slides to both sides of the box body 1, the push plates 9 will lose the restriction of the wedge-shaped blocks 11, and will expand to both sides under the action of the spring 10, facilitating the removal of the packaging bag. When performing heat sealing, the rack 16 can be driven by the cylinder two 15, and the gear 18 can be driven by the rack 16 to rotate. The rotation of the gear 18 can drive the rotating shaft 17 to rotate, so that the transmission rod two 20 rotates accordingly. The transmission rod two 20 will synchronously drive the transmission rods one 19 on both sides, and the transmission rods one 19 will synchronously drive the slide blocks 13 on both sides. Then, the slide blocks 13 on both sides will drive the heat seal strip 14 to clamp towards the center, and perform heat sealing on the bag mouth transported to its center.

[0039] 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, those skilled in the art 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 within the protection scope of the present invention.
