Description

Technical Field

[0001] The utility model relates to the field of medical auxiliary equipment, in particular to a device for automatically printing sample plasma labels. Background Art

[0002] In the medical and biological research fields, the collection, storage, and management of plasma samples are critical for ensuring the accuracy and traceability of experimental results. As the primary container for plasma samples, the labeling information on the sampling tube is crucial for sample registration, tracking, and subsequent analysis. Traditionally, labeling sampling tubes relies heavily on manual labor, which is not only inefficient but also prone to human error, leading to information entry errors or improper labeling, compromising the standardization and automation of sample management.

[0003] With the advancement of automation technology, some automated equipment for labeling sample tubes has emerged on the market. These labelers, typically designed with a robotic arm and conveyor system, automatically grasp the sample tubes, instantly print a label containing sample information using a built-in printer, and precisely affix it to the tube surface. The processed tubes are then automatically returned to their designated racks. This type of equipment significantly reduces the operator's burden and improves labeling accuracy and efficiency, making it a crucial step in laboratory automation upgrades.

[0004] However, despite significant progress in automated labeling, existing labeling machines still face some pressing challenges. This is particularly true regarding label supply, as most labeling machines utilize film-based label paper, with labels adhered to the backing paper. When a roll of labels runs out and needs to be replaced, the process is relatively cumbersome. Users must not only disconnect the current film, but also carefully thread the new label roll's backing paper through multiple guide rollers before attaching it to the reel, ensuring tension on the backing paper and ensuring continuous label transmission. This process is not only time-consuming but also prone to error. After the new film is installed, a section of the label roll typically needs to be passed around all the rollers and secured to the reel. This "pre-run" section of labels cannot be reused and is wasted, increasing consumables. Utility Model Content

[0005] In order to overcome the shortcomings of cumbersome label replacement and increased material waste, the technical problem is to provide a device that can automatically print sample plasma labels and is easy to replace.

[0006] A device for automatically printing sample plasma labels includes a labeling machine base, a reeling roller is rotatably connected to the labeling machine base, a plurality of rollers are provided on the labeling machine base, a thermal print head is installed on the labeling machine base, an air pump is installed on the labeling machine base, both ends of the air pump are connected to an air pipe, a first cylinder is installed on the air pump, a piston rod of the first cylinder is connected to a first suction plate, the first suction plate is slidably connected to the top of the air pump, the first suction plate is connected to the air pump through the air pipe, a second suction plate is connected to the labeling machine base, the second suction plate is connected to the air pump through the air pipe, a notch is opened in the middle of the second suction plate, and a cutter is placed on the side of the second suction plate.

[0007] Optionally, a second cylinder is mounted on the first cylinder, a piston rod of the second cylinder is connected to a connecting frame, and a push plate is connected to a side of the connecting frame away from the second cylinder.

[0008] Optionally, a foam pad is connected to a side of the push plate away from the connecting frame.

DETAILED DESCRIPTION

[0020] The following description is merely a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0021] Example: A device for automatically printing sample plasma labels, such as Figure 1-Figure 4 As shown, it includes a labeling machine base 1, an unwinding roller 101, a passing roller 102, a thermal print head 103, an air pump 2, an air pipe 3, a first air cylinder 4, a first suction plate 5, a second suction plate 6 and a cutter 8. The unwinding roller 101 is rotatably connected to the labeling machine base 1, a plurality of passing rollers 102 are provided on the labeling machine base 1, a thermal print head 103 is installed on the labeling machine base 1, an air pump 2 is installed on the labeling machine base 1, and air pipes 3 are connected to both ends of the air pump 2. The air pipe 3 at one end is connected to the first suction plate 5, and the air pipe 3 at the other end is connected to the second Second suction plate 6, the air pump 2 is equipped with a first air cylinder 4, the piston rod of the first cylinder 4 is connected to the first suction plate 5, the first suction plate 5 is slidably connected to the top of the air pump 2, the first suction plate 5 is connected to the air pump 2 through the air pipe 3, the labeling machine base 1 is connected to the second suction plate 6, the second suction plate 6 is connected to the air pump 2 through the air pipe 3, and a notch 7 is opened in the middle of the second suction plate 6. The design of this notch 7 is very clever. It can allow the cutter 8 to pass easily and effectively prevent the bottom paper from deflecting during cutting. The cutter 8 is placed on the side of the second suction plate 6.

[0022] like Figure 1 and Figure 4 As shown, it also includes a second cylinder 9, a connecting frame 10 and a push plate 11. The second cylinder 9 is installed on the first cylinder 4. The piston rod of the second cylinder 9 is connected to the connecting frame 10. The side of the connecting frame 10 away from the second cylinder 9 is connected to the push plate 11.

[0023] like Figure 1 and Figure 4 As shown, a foam pad 12 is further included, and the foam pad 12 is connected to the side of the push plate 11 away from the connecting frame 10.

[0024] like Figure 1 and Figure 4 As shown, it also includes a limiting rod 13, the top of the second cylinder 9 is connected to the limiting rod 13, and the air supply pipe 3 passes through multiple limiting rods 13.

[0025] like Figure 1 and Figure 4 As shown, a roller 14 is also included. The top of the second cylinder 9 is rotatably connected to the roller 14, and the roller 14 is in contact with the air pipe 3.

[0026] like Figure 1 and Figure 2 As shown, a protective shell 15 is also included. The second suction plate 6 is connected to the protective shell 15, and the protective shell 15 covers the cutter 8.

[0027] After the device is started, the base roll is unwound from the unwinding roller 101 and passes through multiple rollers 102. These rollers 102 ensure that the base paper maintains appropriate tension during the movement, providing a stable foundation for subsequent operations. The base paper continues to move forward and passes through the thermal print head 103 area. At this time, according to the information entered in advance by the medical staff, the thermal print head 103 quickly and accurately prints the required label content on the label of the base paper. After printing is completed, the base paper continues to move to the labeling area, and the robotic arm grabs the sampling tube and labels it. After labeling is completed, the robotic arm puts the sampling tube back into the tube rack.

[0028] When the label roll is about to run out, the air pump 2 is turned on and starts working, drawing air through the air pipe 3, so that the second suction plate 6 generates a strong adsorption force, adsorbing the bottom paper on its surface. At the same time, the operator first removes the cutter 8 and uses the notch 7 in the middle of the second suction plate 6 to accurately cut the old bottom paper. After cutting is completed, the cutter 8 is replaced and completely covered with the protective shell 15 to prevent accidental injury. Then, the exhausted label roll is removed from the unwinding roller 101, and a new label roll is placed on the unwinding roller 101. The bottom paper is pulled out and brought close to the second suction plate 6 to ensure that the two bottom papers can be smoothly connected. After adjustment, the seam between the new and old bottom papers completely overlaps.

[0029] Next, the first air cylinder 4 is started, pushing the first suction plate 5 to move toward the second suction plate 6. Before starting the air pump 2, the operator first places the tape on the first suction plate 5. When the air pump 2 is started, the air is sucked from the air pipe 3, causing the tape to be adsorbed on the first suction plate 5. As the first suction plate 5 moves, the tape gradually approaches and contacts the seam of the bottom paper. At the same time, at the moment of contact between the first suction plate 5 and the second suction plate 6, the tape forms a strong adhesion between the two bottom papers, thereby achieving a seamless connection of the bottom papers. After the bottom papers are connected, the air pump 2 is turned off, and the first cylinder 4 pulls the first suction plate 5, and the first suction plate 5 returns to the air pump 2.

[0030] During the process of pasting the tape, in order to further ensure the firmness of the connection of the backing paper, the second cylinder 9 can be started in time to push the connecting frame 10 and the pushing plate 11 toward the second suction plate 6, and appropriately squeeze the backing paper at both ends of the second suction plate 6. The foam pad 12 not only increases the uniformity of the squeezing, but also avoids damage to the surface of the backing paper due to direct squeezing. After the squeezing is completed, the first cylinder 4 continues to push the first suction plate 5 until the tape is completely pasted in place.

[0031] When the air pipe 3 moves with the first suction plate 5, it slides flexibly on the roller 14 on the top of the second cylinder 9. The rotation of the roller 14 effectively reduces the friction between the air pipe 3 and the second cylinder 9, ensuring the continuous and efficient operation of the air pump 2. At the same time, the air pipe 3 is restricted between multiple limit rods 13. This design not only enhances the stability of the air pipe 3, but also prevents it from touching other moving parts and affecting the operation of other parts, thereby ensuring the smooth progress of the entire labeling process.

[0032] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
