Description

Technical Field

[0001] This utility model relates to the field of blood collection tube label application technology, specifically a pollution-proof label application device for blood collection tubes. Background Technology

[0002] Existing medical blood collection tubes require classification based on user or usage, necessitating pre-placement and labeling for easy differentiation. Currently, labeling involves pre-printing labels and manually affixing them to each tube before arranging them in a tray. Chinese Patent No. CN202320473189.0 provides a device for convenient labeling of blood collection tubes, relating to the field of medical tool technology. This addresses the inefficiency and potential for confusion between different labeled tube types during the labeling and classification process. The labeling machine features a placement block on one side of the label outlet, an adhesive plate on top of the placement block, a tray connected to the top of the adhesive plate, and blood collection tubes connected to the tray. A drive structure is located on the placement block, and a rotating component is located inside the bottom of the tray, with the rotating component engaging with the drive structure. The device uses a drive structure and a rotating component to move a tray containing blood collection tubes along the labeling machine, allowing each blood collection tube to come into contact with the label for application. As the tray moves, the blood collection tubes rotate to wrap the adhesive label around and stick it to the outer wall of the blood collection tube.

[0003] Based on the above, the inventors have discovered the following problems: the above-mentioned device can automatically label blood collection tubes, but it ignores the fact that the edges and corners of the labels are easily not firmly attached; during automatic labeling, although the labels can generally be attached to the blood collection tubes, the edges and corners of the labels are prone to curling or falling off due to uneven glue distribution, excessively fast labeling speed, or label material issues; this not only affects the appearance of the blood collection tubes, but may also cause the labels to detach during transportation or use, resulting in the loss of blood collection tube information and causing trouble for subsequent blood testing and use; moreover, the edges and corners of the labels are difficult to repair manually, which increases workload and cost, and reduces the practicality and reliability of the device.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 The present invention provides a technical solution as follows:

[0022] Example:

[0023] In this embodiment, a device for attaching anti-contamination labels for blood collection tubes includes a base 5 and a label strip 12. The upper end of the base 5 is sequentially provided with an unwinding roller 2, a cutting mechanism 4, a connecting frame 6, a collecting frame 7, and a take-up roller 1 along the moving direction of the label strip 12. The label strip 12 passes sequentially through the unwinding roller 2, the cutting mechanism 4, and the take-up roller 1. A plurality of guiding limiting rollers 3 are provided along the moving path of the label strip 12, and the limiting rollers 3 are fixed to the base 5. One side of the connecting frame 6 is fitted into the collecting frame 7, and the other side is provided with a feeding guide 8. An adhesive assembly is provided on the connecting frame 6.

[0024] The unwinding roller 2 is used to fix the label tape 12 rolls. Then, the movable end of the label tape 12 is passed through several limiting rollers 3, the cutting mechanism 4, the pasting component, and the lower end of the collection frame 7 and connected to the winding roller 1. The cutting mechanism 4 is used to cut the pasting part on the label tape 12 into label strips. The pasting component is used to attach and fix the blood collection tubes to the label strips. The collection frame 7 is used to collect the pasted blood collection tubes. The feeding guide 8 is used to place the blood collection tubes that have not been pasted.

[0025] The adhesive assembly includes a pair of opposing operating cavities 35, a smoothing component 10, a second spring 17, and a first spring 14. The operating cavities 35 are located on the sides of the collection frame 7 and the material feeding guide 8 on the connecting frame 6. Each operating cavity 35 contains a connecting plate 21 and a movable plate 31. The connecting plate 21 is fixedly connected to a rotating shaft 24, which passes through the side wall of the connecting frame 6 and is connected to the output shaft of the motor 16. The connecting frame 6 contains coaxial rotating cavities 1-25 and 2-26. The rotating shaft 24 passes through both rotating cavities and is located within rotating cavity 1-25. A first protrusion 22 is provided, and a second protrusion 23 is provided inside a second rotating cavity 26. The upper end of the first rotating cavity 25 is connected to a first movable cavity 20. A second pusher 19 is provided inside the first movable cavity 20. The second pusher 19 is connected to the top end of the first movable cavity 20 through a second spring 17, and the lower end of the second pusher 19 is in contact with the first protrusion 22. The lower end of the second rotating cavity 26 is connected to another first movable cavity 20. A first pusher 15 is provided inside the first movable cavity 20. The first pusher 15 is connected to the bottom end of the first movable cavity 20 through a first spring 14, and the upper end of the first pusher 15 is in contact with the second protrusion 23.

[0026] The pusher 15 is connected to a connecting rod 13 on one side. The connecting rod 13 passes through the side wall of the connecting frame 6 and is slidably connected to a limiting shaft 33. The limiting shaft 33 is fixed to the inner wall of the connecting frame 6 below the magnetic disk 36. A push plate 32 is provided on the connecting rod 13.

[0027] The rotation of the starter motor 16 drives the rotating shaft 24 to rotate, which in turn drives the second protrusion 23 to rotate. Under the action of the first spring 14, the pusher 15 moves up and down in the movable cavity 20. Under the action of the limit shaft 33, the connecting rod 13 connected to it moves up and down in a stable and synchronous manner, which in turn drives the push plate 32 to move synchronously. The upward movement of the push plate 32 pushes the label strip 12 on it to fit tightly against the blood collection tube. With the blood collection tube rotating with the connecting plate 21, the label strip on the label strip 12 can be firmly stuck to the blood collection tube.

[0028] The electric disk 36 has movable holes 18 on its upper part and on the side of the movable cavity 20. The movable holes 18 are opened in the connecting frame 6. Guide shafts 28 are slidably installed in the movable holes 18. The guide shafts 28 are slidably connected to both ends of the smoothing component 10. One end of the smoothing component 10 passes through the movable hole 18 and is connected to the pusher 19. The output end of the smoothing component 10 is vertically downward and the smoothing component 10 is aligned with the pusher plate 32 in the vertical direction.

[0029] Furthermore, the rotation of the starting motor 16 drives the rotating shaft 24 to rotate, which in turn drives the protrusion 22 on it to rotate. With the cooperation of the spring 17 and the pusher 19, the pusher 19 moves downward and then upward within the movable cavity 20. This causes the smoothing part 10, which is fixedly connected to the pusher 19, to move in the same direction on a pair of guide shafts 28. This allows the lower end of the smoothing part 10 to slightly adhere to the surface of the blood collection tube after it has been pasted, thus smoothing the label pasted on the blood collection tube and preventing the label from curling up after it has been pasted. This further ensures the firm adhesion of the blood collection tube label.

[0030] The movable disk 31 is rotatably connected to an iron disk 30, the iron disk 30 is connected to a spring 29, the spring 29 is connected to an electric disk 36, the electric disk 36 is fixedly installed on the inner wall of the connecting frame 6, the connecting frame 6 is connected to a wire 11, the wire 11 is embedded in the connecting frame 6 and connected to a power source.

[0031] The blood collection tube moves from the feeding guide 8 to between a pair of operating chambers 35. At this time, the wire 11 is energized, causing the magnetic disk 36 to generate magnetism, thereby attracting the movable disk 31 and the iron disk 30 to be located inside the inner wall of the connecting frame 6, so as not to hinder the blood collection tube from falling to the working position of the pair of operating chambers 35 by gravity. When the energization of the wire 11 is turned off, under the action of the spring 329, the iron disk 30 and the movable disk 31 move to the outside of the connecting frame 6, and the movable disk 31 fits tightly with the blood collection tube, thereby fixing the blood collection tube between the movable disk 31 and the connecting disk 21. At this time, the starting motor 16 can drive the rotating shaft 24 to rotate, drive the connecting disk 21 to rotate, thereby driving the blood collection tube to rotate. Combined with the movement of the label tape 12, the label strip on the label tape 12 can be slightly attached to the blood collection tube.

[0032] The electric disk 36, iron disk 30, movable disk 31, connecting disk 21, rotating shaft 24 and the output shaft of motor 16 are coaxially arranged.

[0033] The feeding guide 8 is provided with a guide groove, and the collection frame 7 is provided with a collection groove. The guide groove, the operating cavity 35 and the collection groove are interconnected. The feeding guide 8 is provided with an electric push rod 34, which is used to push the blood collection tube in the operating cavity 35 to the collection frame 7.

[0034] The material feeding guide 8 has a guide groove, the collection frame 7 has a collection groove, and the operating cavity 35, such as... Figure 5 As shown, the output end of the electric push rod 34 faces the operating cavity 35, and the bottom of the operating cavity 35 is an arc shape adapted to the blood collection tube, so that the blood collection tube in the operating cavity 35 can be easily pushed to the collection frame 7.

[0035] Working principle: When the blood collection tube is labeled, firstly, under the action of the take-up roller 1, the unwind roller 2, several limiting rollers 3, and the cutting mechanism 4, the label strip on the label tape 12 moves between the push plate 32 and the smoothing part 10, and the label tape 12 as a whole stops conveying.

[0036] Then, the blood collection tube moves from the feeding guide 8 to between the pair of operating chambers 35. At this time, the wire 11 is energized, causing the magnetic disk 36 to become magnetic, thereby attracting the movable disk 31 and the iron disk 30 to be located within the inner wall of the connecting frame 6. This ensures that the blood collection tube does not obstruct the blood collection tube from falling to the working position of the pair of operating chambers 35 under gravity. Figure 5 As shown; then, the power supply to the wire 11 is disconnected. Under the action of the spring 29, the iron plate 30 and the movable plate 31 move to the outside of the connecting frame 6, and the movable plate 31 fits tightly with the blood collection tube, thereby fixing the blood collection tube between the movable plate 31 and the connecting plate 21; then the motor 16, the winding roller 1 and the unwinding roller 2, the cutting mechanism 4 and several limiting rollers 3 are started, so that the label tape 12 moves horizontally between the smoothing part 10 and the push plate 32;

[0037] Simultaneously, the rotation of motor 16 drives the rotating shaft 24 to rotate, which in turn drives the connecting plate 21 to rotate, thereby causing the blood collection tube to rotate. The design of the movable plate 31 being rotatably connected to the iron plate 30 ensures that the movable plate 31 does not restrict the rotational movement of the blood collection tube and rotates in the same direction as the blood collection tube. The rotation of the rotating shaft 24 also drives the rotation of its protrusions 22 and 23. Figure 3 As shown, the rotation of the second protrusion 23, under the action of the first spring 14, drives the first pusher 15 to perform an operation of first rising and then falling in the movable cavity 20. Thus, under the action of the limit shaft 33, it drives the connecting rod 13 connected to it to perform a stable synchronous up and down movement, and drives the push plate 32 on it to move synchronously. The upward movement of the push plate 32 will push the label strip 12 on it to fit tightly with the blood collection tube. In addition, the blood collection tube rotates with the connecting plate 21, which can firmly stick and fix the label strip on the label strip 12 to the blood collection tube. The cooperation of the first spring 14 and the second protrusion 23 can make the label strip 12 fit tightly with the blood collection tube without over-fixing the label strip 12, causing the label strip 12 to move horizontally.

[0038] Still Figure 3As shown, the rotation of protrusion 22, in cooperation with spring 17 and pusher 19, causes pusher 19 to move downwards and then upwards within the movable cavity 20. This causes smoothing member 10, which is fixedly connected to pusher 19, to move in the same direction on a pair of guide shafts 28. This allows the lower end of smoothing member 10 to slightly adhere to the surface of the blood collection tube after it has been pasted, thus smoothing the label on the blood collection tube and preventing the label from curling up. This further ensures the firmness of the blood collection tube label, reduces the occurrence of label curling and falling off, improves the appearance of the blood collection tube, reduces the possibility of label detachment and loss of blood collection tube information during transportation, reduces workload and cost, and improves the practicality and reliability of blood collection tube label application.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
