Description

Technical Field

[0001] This utility model relates to the technical field of label peeling equipment, and in particular to a label peeling mechanism. Background Technology

[0002] In the express packaging industry, label application is an essential step, requiring efficient label application equipment. Traditional label peeling mechanisms suffer from several problems in practical applications. For example, labels are prone to breakage. When this happens, operators often need to disassemble the feed roller to reinsert and pad the label before reinstalling it – a cumbersome and time-consuming process. Furthermore, existing label peeling mechanisms have poor adaptability, struggling to accommodate labels of different sizes and materials, leading to frequent peeling failures and impacting production efficiency and quality. Additionally, traditional label peeling mechanisms are complex, requiring time-consuming and labor-intensive assembly, and incurring high maintenance costs, further limiting their widespread application in high-efficiency logistics environments. To address these issues, there is an urgent need for a label peeling mechanism that effectively prevents breakage, is highly adaptable, has a simple structure, and is easy to maintain, to meet the high-efficiency operational needs of industries such as e-commerce express packaging, cloud warehouse shipping, and logistics packaging. Utility Model Content

[0003] The purpose of this invention is to provide a label peeling mechanism to overcome the shortcomings of the existing technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A label peeling mechanism includes a sheet metal mounting base, a torsion spring, a positioning sheet metal, a peeling plate, a paper-pressing and glue-coating roller, a roller, a retaining ring, a buffer groove, a snap-fit ​​groove, and an abutment end, wherein: The sheet metal mounting base, as the basic component of the overall mechanism, is used to fix it on the labeling machine frame. A pair of positioning sheet metals are provided at each end, and a roller is installed between the positioning sheet metals. The roller and the positioning sheet metals form a rotatable connection, allowing the roller to move freely within a certain range to accommodate label paper of different thicknesses. Furthermore, a buffer groove is formed on the inner side of the positioning sheet metal, through which both ends of the roller pass and can move up and down within the buffer groove. The design of the buffer groove allows the roller to automatically adjust its position according to the actual thickness of the label paper, avoiding problems of excessive or insufficient pressure due to variations in label paper thickness.

[0005] Specifically, the torsion spring is mounted on a positioning sheet metal, with two abutment ends extending from each end. One abutment end abuts against the roller, and the other abuts against the sheet metal mounting base. The torsion spring applies a downward force to the roller through its elastic deformation, ensuring the roller remains under constant pressure. Furthermore, the torsion springs are configured as a pair, each mounted on one of the positioning sheet metal sides, to achieve balanced pressure adjustment on both sides of the roller. This design allows the roller to adaptively adjust the pressure according to the thickness of the label paper during operation, preventing paper breakage due to uneven force.

[0006] Furthermore, a paper-pressing and adhesive-coating roller is fitted onto the roller, forming a rotatable connection with the roller. During the label peeling process, the paper-pressing and adhesive-coating roller rolls along with the label paper being fed, reducing adhesive residue on the label paper surface. Specifically, when changing label paper, the paper-pressing and adhesive-coating roller can be lifted and opened by the print head, facilitating the user's paper feeding operation; after feeding, the paper-pressing and adhesive-coating roller retracts with the print head under the action of a torsion spring, pressing the label paper again and ensuring the stability of the label paper during the peeling process.

[0007] The roller has a pair of annular positioning grooves on its two end sidewalls, with retaining rings engaging in these grooves. The retaining rings are arranged in pairs on both sides of the positioning sheet metal to limit the position of the roller and ensure its stable installation. Furthermore, the top of the positioning sheet metal has a downwardly recessed engaging groove, into which one end of the torsion spring abuts, achieving precise positioning of the torsion spring. Through this design, the connection between the roller and the positioning sheet metal is tighter and more reliable, reducing the possibility of loosening or misalignment during mechanism operation.

[0008] Furthermore, the peeling plate mounting base is fixedly mounted on one side of the sheet metal mounting base for mounting the peeling plate. The peeling plate is formed by bending, with its end bent at a certain angle, to cooperate with the pressure roller. During the label peeling process, the backing paper passes through the area between the pressure roller and the peeling plate, moving along the bent portion of the peeling plate. Specifically, the bent portion of the peeling plate is designed as an arc, with its radius of curvature precisely calculated to ensure that the backing paper maintains stable tension during the peeling process. In addition, the take-up roller provides a feeding force to the backing paper, ensuring that the backing paper always adheres to the bent portion of the peeling plate, thereby improving the success rate of label peeling.

[0009] Specifically, the gap between the peeling plate and the pressure roller can be adjusted according to the thickness of the label paper. This adjustment is achieved by changing the initial deformation of the torsion spring to adjust the height of the roller, thereby changing the distance between the pressure roller and the peeling plate. This adjustment mechanism allows the label peeling mechanism to be compatible with label papers of different sizes and materials, significantly improving the adaptability of the equipment.

[0010] Furthermore, the sheet metal mounting base adopts a modular design, with components connected by bolts or snap-fit ​​connections for quick assembly and disassembly. This design not only simplifies the equipment installation process but also reduces maintenance costs. In particular, the machining precision of the buffer groove and snap-fit ​​groove is strictly controlled to ensure that the rollers and torsion springs do not loosen or deviate from their predetermined positions during operation.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: First, the adaptive pressure adjustment function provided by the torsion spring solves the paper breakage problem caused by uneven force in traditional label peeling mechanisms. The torsion spring design allows the roller to automatically adjust the pressure according to the thickness of the label paper during operation, thus avoiding paper breakage caused by excessive or insufficient pressure. Second, the combined design of the buffer groove and torsion spring makes the equipment compatible with label papers of different specifications and materials, significantly improving its applicability. Third, the modular design simplifies the assembly and maintenance process, reducing maintenance costs. Finally, the combined use of the pressure roller and peeling plate significantly improves the success rate of label peeling, especially demonstrating excellent performance when handling highly viscous label paper.

[0012] In summary, this utility model achieves efficient label peeling by rationally configuring key components such as the sheet metal mounting base, torsion spring, positioning sheet metal, peeling plate, pressure and glue-coating roller, roller, retaining ring, buffer groove, snap-fit ​​groove, and abutment end. The connections and interactions between these components are carefully designed to ensure the stability and reliability of the equipment. This utility model's technical solution not only solves the technical problems of traditional label peeling mechanisms but also has strong practicality and promotional value, and can be widely applied in industries such as e-commerce express packaging, cloud warehouse shipping, and logistics packaging.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0018] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings: A label peeling mechanism for a labeling machine, combined with Figure 1 and Figure 2 As shown, the specific implementation method is as follows. The sheet metal mounting base 1, as the basic component of the overall mechanism, is fixedly installed on the labeling machine frame. A pair of positioning sheet metals 3 are fixed to its two ends by bolts or clips. A roller 6 is provided between the positioning sheet metals 3, forming a rotatable connection between the roller 6 and the positioning sheet metals 3, allowing the roller 6 to move freely within a certain range. Both ends of the roller 6 pass through buffer grooves 8 on the positioning sheet metals 3 and can move up and down within the buffer grooves 8. The design of the buffer grooves 8 allows the roller 6 to automatically adjust its position according to the actual thickness of the label paper 11, avoiding problems of excessive or insufficient pressure due to changes in label paper thickness. A pair of annular positioning slots are opened on the side walls of both ends of the roller 6, and retaining rings 7 are engaged in the positioning slots. The retaining rings 7 are arranged in pairs on both sides of the positioning sheet metal 3 to limit the position of the roller 6, ensuring the stable installation of the roller 6.

[0019] A torsion spring 2 is installed on the inner side of the positioning sheet metal 3. The two abutting ends 10 of the torsion spring 2 extend to the roller 6 and the sheet metal mounting base 1, respectively. One abutting end 10 abuts against the roller 6, and the other abutting end 10 abuts against the sheet metal mounting base 1. The torsion spring 2 applies a downward force to the roller 6 through its elastic deformation, ensuring that the roller 6 remains in a constant compressed state. Furthermore, the torsion spring 2 is configured as a pair, installed on the positioning sheet metal 3 on both sides, to achieve balanced adjustment of the pressure on both sides of the roller 6. A downwardly recessed locking groove 9 is provided on the top of the positioning sheet metal 3, and one abutting end 10 of the torsion spring 2 abuts into the locking groove 9, thereby achieving precise positioning of the torsion spring 2. Through the above design, the connection between the roller 6 and the positioning sheet metal 3 is tighter and more reliable, reducing the possibility of loosening or misalignment during mechanism operation.

[0020] A paper-pressing and adhesive-coating roller 5 is fitted onto the roller 6, forming a rotatable connection with the roller 6. During the label paper 11 peeling process, the paper-pressing and adhesive-coating roller 5 rolls along with the label paper 11, reducing adhesive residue on the label paper surface. When the label paper 11 needs to be replaced, the paper-pressing and adhesive-coating roller 5 can be lifted and opened by the print head, facilitating the user to complete the paper feeding operation. After paper feeding is completed, the paper-pressing and adhesive-coating roller 5, under the action of the torsion spring 2, closes back with the print head, pressing the label paper 11 again to ensure the stability of the label paper 11 during the peeling process. The paper-pressing and adhesive-coating roller 5 is made of highly wear-resistant rubber material, and its outer surface has undergone special treatment to effectively prevent the label paper 11 from slipping during rolling.

[0021] A peeling plate mounting base 12 is fixedly mounted on one side of a sheet metal mounting base 1 for mounting the peeling plate 4. The peeling plate 4 is formed by bending, with its end bent at a certain angle, to cooperate with the pressure roller 5. During the peeling process of the label paper 11, the backing paper passes through the area between the pressure roller 5 and the peeling plate 4, moving along the bent part of the peeling plate 4. The bent part of the peeling plate 4 is designed as an arc, and its radius of curvature is precisely calculated to ensure that the backing paper maintains stable tension during the peeling process. In addition, the take-up roller provides a feeding force to the backing paper, ensuring that the backing paper always adheres to the bent part of the peeling plate 4, thereby improving the success rate of label peeling. The gap between the peeling plate 4 and the pressure roller 5 can be adjusted according to the thickness of the label paper 11. The adjustment method is to adjust the height of the roller 6 by changing the initial deformation of the torsion spring 2, thereby changing the distance between the pressure roller 5 and the peeling plate 4. This adjustment mechanism allows the label peeling mechanism to be compatible with label papers 11 of different specifications and materials, significantly improving the applicability of the equipment.

[0022] The sheet metal mounting base 1 adopts a modular design, with components connected by bolts or snap-fit ​​connections for quick assembly and disassembly. This design not only simplifies the installation process but also reduces maintenance costs. In particular, the machining precision of the buffer groove 8 and the snap-fit ​​groove 9 is strictly controlled to ensure that the roller 6 and torsion spring 2 do not loosen or deviate from their predetermined positions during operation. The bottom of the sheet metal mounting base 1 has multiple mounting holes for securing it to the labeling machine frame. The diameter and spacing of the mounting holes are precisely designed to ensure that the sheet metal mounting base 1 can adapt to different models of labeling machines, improving the equipment's versatility.

[0023] In actual operation, the label paper 11 enters the label peeling mechanism of this invention from the external paper feeding device. The label paper 11 first passes through the area between the pressure roller 5 and the peeling plate 4. The pressure roller 5 rolls along with the label paper 11, reducing adhesive adhesion on the label paper surface. After passing through the area between the pressure roller 5 and the peeling plate 4, the backing paper moves along the bend of the peeling plate 4 and is wound up by the take-up roller. During this process, the torsion spring 2 applies a downward force to the roller 6 through its elastic deformation, keeping the roller 6 in a constant pressure state and ensuring the stability of the label paper 11 during peeling. When it is necessary to replace the label paper 11, the user can manually lift the print head, causing the pressure roller 5 to open and facilitate paper feeding. After paper feeding is completed, the print head automatically closes under the action of the torsion spring 2, and the pressure roller 5 presses down on the label paper 11 again, ensuring the equipment returns to normal operation.

[0024] The technical advantages of this invention are reflected in the following aspects. The adaptive pressure adjustment function provided by the torsion spring 2 solves the paper breakage problem caused by uneven force in traditional label peeling mechanisms. The design of the torsion spring 2 allows the roller 6 to automatically adjust the pressure according to the thickness of the label paper 11 during operation, thus avoiding paper breakage due to excessive or insufficient pressure. The combined design of the buffer groove 8 and the torsion spring 2 makes the equipment compatible with label papers 11 of different specifications and materials, significantly improving the applicability of the equipment. The modular design simplifies the assembly and maintenance process of the equipment, reducing maintenance costs. The combined use of the pressure roller 5 and the peeling plate 4 significantly improves the success rate of label peeling, especially exhibiting excellent performance when handling highly viscous label paper 11.

[0025] The label peeling mechanism of this invention has broad application prospects in industries such as e-commerce express packaging, cloud warehouse shipping, and logistics packaging. For example, in e-commerce express packaging scenarios, label paper 11 often needs to be replaced frequently, and the specifications and materials of label paper 11 may change due to order requirements. This invention, through the design of torsion spring 2 and buffer groove 8, can quickly adapt to label paper 11 of different specifications and materials, significantly improving work efficiency. In cloud warehouse shipping scenarios, the success rate of label paper 11 peeling directly affects shipping efficiency. This invention, through the cooperative use of pressure paper coating roller 5 and peeling plate 4, can ensure the stability of label paper 11 during the peeling process, thereby improving shipping efficiency. In logistics packaging scenarios, the frequent replacement of label paper 11 and long-term operation place higher demands on the stability and reliability of the equipment. This invention, through modular design and high-precision processing, can meet the high-intensity usage requirements in logistics packaging scenarios.

[0026] In summary, this utility model achieves efficient label peeling by rationally configuring key components such as the sheet metal mounting base 1, torsion spring 2, positioning sheet metal 3, peeling plate 4, paper-pressing and glue-coating roller 5, roller 6, retaining ring 7, buffer groove 8, snap-fit ​​groove 9, and abutment end 10. The connection relationship and interaction between the components have been carefully designed to ensure the stability and reliability of the equipment operation. The technical solution of this utility model not only solves the technical problems existing in traditional label peeling mechanisms, but also has strong practicality and promotional value, and can be widely used in e-commerce express packaging, cloud warehouse shipping, logistics packaging and other industries.
