Description

Technical Field

[0001] This utility model relates to the field of syringe label technology, specifically to a label applicator. Background Technology

[0002] In the medical device industry, syringes are common medical devices widely used in areas such as drug injection, vaccination, and blood collection. To ensure the safe use of medications and patient health, the labeling information on syringes is crucial, typically including the drug name, dosage, expiration date, and batch number. With the increasing demands for safety and standardized management in the medical industry, the accuracy and readability of syringe labels have become particularly important.

[0003] Traditional labeling methods typically rely on large labeling machines. While these machines are suitable for large-scale production lines, their large size, space requirements, and operational complexity often make them unsuitable for small-batch, multi-variety production environments. Furthermore, the frequent label changes and parameter adjustments required by these large machines lead to inefficiencies and high costs, making them unsuitable for the needs of small-batch, multi-variety production.

[0004] Moreover, syringes typically have smooth surfaces and vary considerably in shape and size, making label application more difficult. Existing labelers are not only time-consuming and labor-intensive during the label application process, but also struggle to guarantee the label's application accuracy and positional consistency. This results in inaccurate, skewed, or off-target label placement, which in turn affects product quality control and safety. Utility Model Content

[0005] In view of this, the present invention provides a labeling device to address the problems of poor syringe fixation and low labeling accuracy of existing syringe labeling devices.

[0006] This utility model provides a labeling device, comprising: a main body; a first fixing member connected to a first side of the main body, the first fixing member having a fixing countersunk hole; a second fixing member connected to the first side of the main body, a gap being formed between the main body and the second fixing member, the main body forming a labeling working area between the first fixing member and the second fixing member; the second fixing member having a fixing through hole, the inner diameter of the fixing through hole being larger than the body diameter of the workpiece to be labeled and smaller than the rolled edge diameter of the workpiece to be labeled; and a reinforcing member combined with the second fixing member, forming a limiting gap between the reinforcing member and the second fixing member for axially limiting the rolled edge of the workpiece to be labeled.

[0007] With the above configuration, the first fixing member provides stable support to the first end of the workpiece through the countersunk hole, ensuring accurate initial positioning of the workpiece during the labeling process. The second fixing member has a through hole with an inner diameter designed to be larger than the workpiece's body diameter but smaller than its rolled edge diameter. This dimensional matching effectively prevents radial slippage of the workpiece during labeling and provides support for the rolled edge, further improving the fixing effect. The combination of the reinforcement and the second fixing member, through the formed limiting interval, axially limits the rolled edge of the workpiece, enhancing the overall stability of the workpiece and preventing workpiece displacement caused by rotation or external forces during labeling. The combination of the main body, the first fixing member, the second fixing member, and the reinforcement enables the labeler to reliably fix the workpiece and perform precise labeling operations during use.

[0008] Optionally, the main body is provided with an arc-shaped groove, the curvature of which is adapted to the surface curvature of the labeling area of ​​the workpiece to be labeled, the arc-shaped groove is concentrically arranged with the fixed countersunk hole, and the inner diameter of the arc-shaped groove is smaller than the inner diameter of the fixed countersunk hole.

[0009] With the above-described design, the arc-shaped groove on the main body can precisely fit the surface of the area to be labeled on the workpiece, thus providing more stable support during the labeling process. Because the arc-shaped groove is concentric with the countersunk hole, the workpiece maintains precise axial positioning during fixation, effectively preventing labeling position shifts caused by eccentricity. Simultaneously, the inner diameter of the arc-shaped groove is smaller than the inner diameter of the countersunk hole, allowing it to locally limit the area to be labeled on the workpiece, enhancing the fixing effect and reducing shaking or displacement during labeling, thereby improving labeling stability and label adhesion quality.

[0010] Optionally, the fixed through hole is eccentrically positioned relative to the fixed countersunk hole in a direction away from the arc-shaped groove.

[0011] With the above configuration, the fixed through hole is offset from the fixed countersunk hole in a direction away from the arc-shaped groove, ensuring that one end of the workpiece is closer to the labeling area of ​​the arc-shaped groove when fixed. This optimizes the stress distribution on the workpiece during labeling, ensuring its stability within the labeling working area and preventing axial or radial displacement. It also helps to provide more operating space for labeling operations, improving the convenience and accuracy of labeling.

[0012] Optionally, the reinforcing member has a plurality of members spaced apart around the fixing through hole, and the reinforcing member is fixedly connected to the second fixing member by a bracket.

[0013] With the above-described arrangement, the reinforcement components are spaced apart around the fixing through holes, providing support and restraint for the rolled edges of the workpiece from multiple directions, further enhancing the stability of the workpiece during the labeling process. The arrangement of multiple reinforcement components improves the overall load-bearing capacity and applicability of the labeler, enabling it to adapt to the fixing requirements of workpieces of different specifications, thereby improving labeling efficiency and quality.

[0014] Optionally, the second fastener is a plate-like structure, and the reinforcing member is detachably connected to the second fastener via a plug-in connection.

[0015] With the above configuration, the second fixing component adopts a plate-like structure, providing a stable and easy-to-operate support base. The reinforcing member is detachably connected to the second fixing component via a plug-in method, giving the labeler greater flexibility and adjustability. This facilitates quick installation and removal of the reinforcing member and allows for flexible adjustment of the reinforcing member layout according to the size and shape of different workpieces, meeting the labeling needs of various workpieces. Furthermore, the detachable structural design facilitates equipment maintenance and cleaning, while extending the labeler's service life and improving ease of use and economy.

[0016] Optionally, the fixing through hole is a U-shaped through hole that opens toward the extraction direction of the reinforcement.

[0017] With the above configuration, the fixed through-hole is a U-shaped through-hole opening towards the extraction direction of the reinforcement, facilitating quick placement or removal of the workpiece from the side without requiring axial insertion or extraction through the through-hole. This effectively improves operational efficiency, especially in situations requiring frequent workpiece changes, significantly shortening loading and unloading time. Simultaneously, the U-shaped through-hole ensures workpiece positioning stability while reducing potential wear on the workpiece surface during operation, enhancing the practicality and convenience of the labeler.

[0018] Optionally, the reinforcement has a slot for inserting the second fastener, a notch below the slot for avoiding the workpiece to be labeled, and a limiting portion above the slot for pressing against the rolled edge of the workpiece to be labeled.

[0019] With the above-described design, the slot design of the reinforcement component allows for easy insertion of the second fastener, providing a stable connection and support. The notch design below the slot prevents interference with the workpiece to be labeled, ensuring the workpiece can be placed smoothly and held in the correct position. The limiting part above the slot provides additional axial support to the workpiece by pressing against its rolled edge, preventing displacement or tilting during labeling. This improves the workpiece's fixing accuracy and avoids inaccurate labeling caused by unstable workpiece positioning.

[0020] Optionally, the limiting portion includes at least two first pressure blocks extending along the insertion direction parallel to the reinforcement member.

[0021] With the above configuration, the limiting part includes at least two first pressure blocks extending parallel to the insertion direction of the reinforcing member, enhancing the fixing effect on the rolled edge of the workpiece. The first pressure blocks apply pressure evenly, ensuring that the workpiece does not shift or skew during the labeling process, while also preventing damage to the workpiece due to uneven pressure. This provides more stable support, especially when handling workpieces of different sizes and shapes, ensuring better accurate label application.

[0022] Optionally, the limiting portion includes at least one second pressure block extending along the insertion direction perpendicular to the reinforcement member.

[0023] With the above configuration, the limiting part includes at least one second pressure block extending perpendicular to the insertion direction of the reinforcement, which helps to provide additional positioning support for the workpiece in the vertical direction. This effectively prevents the workpiece from shifting or becoming unstable in the vertical direction during the labeling process, ensuring precise positioning of the workpiece throughout the entire labeling operation.

[0024] Optionally, the second pressure block has two spaced-apart sections.

[0025] The above settings evenly fix the workpiece, preventing it from tilting or shifting during labeling, thus improving the stability and accuracy of the labeling process. The spaced design also ensures that the pressure block does not have excessive contact with the workpiece surface, reducing damage or wear and further extending the lifespan of the labeler and the protection of the workpiece.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0041] The following is combined with Figures 1 to 3 This describes a specific embodiment of the present invention, namely, the reinforcement 4 and the second fixing member 3 are an integral structure.

[0042] like Figure 1 The image shows a specific implementation of the labeler provided in this embodiment, which includes: a main body 1, a first fixing member 2, a second fixing member 3, and a reinforcing member 4.

[0043] Specifically, the first fixing member 2 is connected to the first side of the main body 1, and the first fixing member 2 has a fixing countersunk hole 5; the second fixing member 3 is connected to the first side of the main body 1, and there is a gap between the main body 1 and the second fixing member 3, and the main body 1 forms a labeling working area between the first fixing member 2 and the second fixing member 3; the second fixing member 3 has a fixing through hole 6, and the inner diameter of the fixing through hole 6 is larger than the body diameter of the workpiece to be labeled and smaller than the rolled edge diameter of the workpiece to be labeled; the reinforcing member 4 is combined with the second fixing member 3, and a limiting interval is formed between the reinforcing member 4 and the second fixing member 3 for axially limiting the rolled edge of the workpiece to be labeled.

[0044] In this embodiment, the first fixing member 2 securely fixes the first end of the workpiece through the fixing countersunk hole 5, ensuring that the workpiece remains stationary within the working area. The inner diameter of the fixing through hole 6 of the second fixing member 3 is larger than the body diameter of the workpiece but smaller than the rolled edge diameter, effectively preventing displacement of the workpiece during labeling and providing more stable support. The reinforcing member 4 cooperates with the second fixing member 3 to form a limiting interval, further enhancing the fixing effect of the rolled edge of the workpiece and ensuring that the workpiece to be labeled maintains accurate positioning during the labeling operation. The labeler can effectively improve labeling accuracy, avoid label skew or positional shift caused by workpiece instability, and ensure the efficiency and accuracy of the labeling process.

[0045] It should be noted that the workpiece in this embodiment is not limited to a pre-filled syringe, but may also include other cylindrical objects similar to syringes or similar parts that need to be labeled. In the following description, a pre-filled syringe will be used as the workpiece in this embodiment.

[0046] like Figure 2 As shown, this is a specific implementation of the labeler provided in this embodiment. The main body 1 is provided with an arc-shaped groove 7. The curvature of the arc-shaped groove 7 is adapted to the surface curvature of the labeling area of ​​the workpiece to be labeled. The arc-shaped groove 7 is concentrically arranged with the fixed countersunk hole 5. The inner diameter of the arc-shaped groove 7 is smaller than the inner diameter of the fixed countersunk hole 5.

[0047] Specifically, because the inner diameter of the arc-shaped groove 7 is smaller than the inner diameter of the fixing countersunk hole 5, additional support is provided inside the fixing countersunk hole 5. This support can firmly fix the area of ​​the syringe to be labeled within the working area, preventing the syringe from shifting or becoming unstable during labeling. This ensures that the syringe remains in the correct position during labeling, avoiding label misalignment or skew. Furthermore, the arc-shaped groove 7 matches the surface curvature of the syringe, allowing the labeler to more precisely conform to the syringe surface, improving labeling accuracy and stability, thereby enhancing the overall labeling quality.

[0048] like Figure 3 As shown, this is a specific implementation of the labeler provided in this embodiment. The fixing through hole 6 is eccentrically positioned relative to the fixing countersunk hole 5 in a direction away from the arc-shaped groove 7.

[0049] Specifically, the fixing through hole 6 is offset relative to the fixing countersunk hole 5, pointing away from the arc-shaped groove 7, so that when the syringe is fixed, one end is kept closer to the labeling area of ​​the arc-shaped groove 7. This optimizes the force distribution on the syringe during the labeling process, ensuring the stability of the syringe within the labeling working area, while avoiding axial or radial displacement of the syringe.

[0050] like Figure 1 As shown, this is a specific implementation of the labeler provided in this embodiment. The reinforcement 4 has a plurality of parts spaced around the fixing through hole 6. The reinforcement 4 is fixedly connected to the second fixing member 3 by a bracket.

[0051] Specifically, the reinforcing member 4 has two parts symmetrically arranged with respect to the fixing through hole 6. This symmetrical arrangement ensures even fixation of the syringe. After the curled edge of the syringe abuts against the second fixing member 3, rotating the syringe positions the curled edge below the fixing bracket, thereby reinforcing the syringe. The reinforcing member 4 is fixedly connected to the second fixing member 3 via the bracket, ensuring that the reinforcing member 4 remains in the predetermined position during use and does not loosen or shift.

[0052] In other embodiments, the number and arrangement of the reinforcement members 4 can be flexibly adjusted according to the actual rolled edge shape of the workpiece to be labeled.

[0053] The following is combined with Figures 4 to 11 Other specific embodiments of the present invention are described below, namely, the reinforcement 4 and the second fixing member 3 are detachable structures.

[0054] like Figure 4 As shown, this is a second specific implementation of the labeler provided in this embodiment. The second fixing member 3 is a plate-shaped structure, and the reinforcing member 4 is detachably connected to the second fixing member 3 by plugging in.

[0055] Specifically, the second fixing component 3 is a plate-like structure, providing a stable support surface, which gives the entire labeler good stability and load-bearing capacity. The reinforcing component 4 is detachably connected to the second fixing component 3 via a plug-in connection, allowing the reinforcing component 4 to be easily installed and removed as needed, increasing the flexibility and maintainability of the labeler. When it is necessary to replace or adjust the reinforcing component 4, the operation can be completed quickly, improving production efficiency.

[0056] like Figure 5As shown, this is a second specific implementation of the labeler provided in this embodiment. The fixing through hole 6 is a U-shaped through hole 8 that opens towards the pull-out direction of the reinforcement 4.

[0057] Specifically, the U-shaped through-hole 8, opening towards the withdrawal direction of the reinforcement 4, allows for easier and faster insertion or removal of the workpiece from the side, avoiding the inconvenience of vertical insertion. The opening of the U-shaped through-hole 8 facing the withdrawal direction of the reinforcement 4 simplifies the syringe loading and unloading process, reduces friction between the workpiece and the fixed through-hole 6, and prevents surface damage or deformation of the workpiece due to excessive friction. This makes the labeling process more efficient, especially in production environments requiring frequent syringe changes, significantly improving operating speed.

[0058] like Figure 6 , Figure 7 As shown, this is a second specific embodiment of the labeler provided in this embodiment. The reinforcement 4 has a slot for inserting the second fixing member 3. The slot has a notch below it for avoiding the workpiece to be labeled, and a limiting part above it for pressing on the rolled edge of the workpiece to be labeled.

[0059] Specifically, the slot is formed by two rectangular blocks 9 symmetrically arranged parallel reinforcing members 4 in the insertion direction and a connecting rod 10 connecting the two rectangular blocks 9. The connecting rod 10 is used to abut against the lower surface of the second fixing member 3. The slot facilitates a stable connection between the reinforcing member 4 and the second fixing member 3. The lower part of the slot is provided with a notch to avoid interference with the surface of the syringe during insertion and fixing, so that the syringe can be placed smoothly and accurately docked. The upper part of the slot is provided with a limiting part to press against the upper edge of the syringe. The limiting part provides additional support to prevent the syringe from shifting or tilting during the labeling process, thereby ensuring that the syringe is always in the correct position, effectively enhancing the fixing stability of the syringe and improving the accuracy of the labeling process.

[0060] like Figure 6 As shown, this is a second specific implementation of the labeler provided in this embodiment. The limiting part includes at least two first pressing blocks 11 extending in a direction parallel to the insertion direction of the reinforcing member 4.

[0061] Specifically, the limiting part includes at least two first pressure blocks 11 extending parallel to the insertion direction of the reinforcing member 4. After the syringe is inserted into the fixed countersunk hole 5 through the fixed through hole 6, the insertion of the reinforcing member 4 and the second fixing member 3 places the limiting part above the syringe curled edge, effectively limiting the curled edge and ensuring the stability of the syringe during the labeling process. By setting symmetrically distributed first pressure blocks 11, the displacement of the workpiece can be effectively limited, preventing it from tilting or shifting, ensuring that the curled edge of the workpiece is uniformly pressed, and further enhancing the fixing effect of the workpiece.

[0062] like Figure 8 , Figure 9 As shown, this is a third specific implementation of the labeler provided in this embodiment. The limiting part includes at least one second pressing block 12 extending along the insertion direction perpendicular to the reinforcing member 4.

[0063] Specifically, the limiting part includes at least one second pressure block 12 extending perpendicular to the insertion direction of the reinforcing member 4, effectively limiting the vertical displacement of the syringe, preventing the syringe from shaking or shifting during operation, and ensuring that the syringe always remains in the predetermined position. This helps improve labeling accuracy, avoids labeling deviations caused by workpiece instability, and thus improves the reliability and consistency of the entire labeling process.

[0064] like Figure 10 , Figure 11 As shown, this is the fourth specific implementation of the labeler provided in this embodiment, wherein the second pressure block 12 has two spaced-apart rods.

[0065] Specifically, the second pressure block 12 has two spaced-apart sections to ensure more stable fixation of the syringe. The two spaced-apart second pressure blocks 12 can effectively distribute the pressure applied to the syringe. The workpiece can receive more uniform support during the labeling process, preventing tilting or displacement caused by uneven force, and further improving the accuracy and consistency of labeling.

[0066] Working principle:

[0067] The syringe is first placed inside the main body 1, and one end of the syringe is securely fixed by the fixing countersunk hole 5 of the first fixing member 2. Simultaneously, the fixing through hole 6 of the second fixing member 3 matches the rolled edge of the syringe, ensuring stability during labeling. The reinforcing member 4, through a fixed connection or plug-in method, cooperates with the second fixing member 3 to provide additional fixing pressure, ensuring the other end of the syringe is effectively fixed. During the labeling operation, the syringe is vertically restricted by the limiting part (including multiple pressure blocks) to prevent displacement or tilting during labeling, ensuring the label is accurately and neatly attached to the syringe surface. Through the adjustable reinforcing member 4 and the limiting part, the labeler can adapt to different syringe sizes and shapes, achieving a fast and high-precision labeling process. The entire system, through a reasonable fixing structure and support design, not only improves the positioning accuracy of the syringe but also reduces the influence of human factors, thereby improving labeling efficiency and quality.

[0068] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and all such modifications and variations fall within the scope of the present invention.
