Description

Technical Field

[0001] This utility model relates to the field of magnetic roller technology, and in particular to a limiting component for magnetic rollers. Background Technology

[0002] In the field of printing labels and die-cutting technology, a flexible die-cutting plate is adsorbed onto a roller with magnetic adsorption capability. The rotation of the roller causes the die-cutting plate to cut a specified shape on the material.

[0003] In existing technologies, magnetic rollers are used in conjunction with flexible die-cutting plates for die-cutting. Generally, the flexible die-cutting plate is attached to the outer surface of the magnetic roller, and finally the two free ends of the flexible die-cutting plate come into contact. In this process, it is difficult to ensure the positional stability of the flexible die-cutting plate by relying solely on the adsorption force of the magnetic roller. It is very easy for the position to shift along the axis of the magnetic roller, which has a negative impact on the die-cutting process.

[0004] Therefore, this utility model proposes a limiting component for magnetic rollers to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a limiting component for magnetic rollers to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a limiting component for a magnetic roller, comprising an annular limiting groove disposed on the outer cylindrical surface of the magnetic roller body and a limiting clip disposed on the bottom side of the flexible die-cutting plate; Rotating shafts are provided at both ends of the magnetic roller body; The limiting clips on the bottom side of the flexible die-cutting plate are set at equal intervals.

[0007] Preferably, two sets of annular limiting grooves are symmetrically arranged on the outer side of the magnetic roller body.

[0008] Preferably, the limiting card body is fitted and locked in the annular limiting groove.

[0009] Preferably, an auxiliary groove is provided on one side of the annular limiting groove, the auxiliary groove being connected to the annular limiting groove and parallel to the axis of the magnetic roller body.

[0010] Preferably, the flexible die-cutting blade is wound and attached to the outer cylindrical surface of the magnetic roller body to form a cylindrical die-cutting blade, which is assisted in limiting its position by an auxiliary component.

[0011] Preferably, the auxiliary component includes a positioning slot and a concave rubber strip, with the positioning slot provided on one side of the limiting card body near the end of the flexible die-cutting plate.

[0012] Preferably, both ends of the concave rubber strip are engaged with the positioning grooves on the side wall of the limiting card body; A push-pull buckle is also fixedly installed on the side wall of the concave rubber clip.

[0013] Compared with the prior art, the beneficial effects of this utility model are: The magnetic roller designed in this utility model mainly uses an annular limiting groove on the outer cylindrical surface of the magnetic roller body and a limiting clip on the bottom side of the flexible die-cutting plate to provide axial position limiting for the flexible die-cutting plate. On this basis, the flexible die-cutting plate is wrapped and attached to the outer cylindrical surface of the magnetic roller body to form a cylindrical die-cutting plate. This cylindrical die-cutting plate is further stabilized by an auxiliary component, namely, the concave rubber clip in the auxiliary component is used to engage with the positioning groove on the side wall of the limiting clip, providing a stabilizing effect at the joint of the two ends of the flexible die-cutting plate, thus preventing the joint of the two ends from loosening when the flexible die-cutting plate is working.

[0015] In the figure: magnetic roller body 1, annular limiting groove 101, auxiliary groove 102, rotating shaft 2, flexible die-cutting plate 3, limiting card body 301, positioning card groove 401, concave rubber card strip 402, push-pull buckle 403. Detailed Implementation

[0016] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Example 1 Please refer to Figures 1 to 5 This utility model provides a technical solution: a limiting component for a magnetic roller, including an annular limiting groove 101 disposed on the outer cylindrical surface of the magnetic roller body 1 and a limiting clip 301 disposed on the bottom side of the flexible die-cutting plate 3; and rotating shafts 2 are disposed at both ends of the magnetic roller body 1.

[0018] In this solution, during the use of the magnetic roller, an annular limiting groove 101 is provided on its outer cylindrical surface to cooperate with the limiting clip 301 on the bottom side of the flexible die-cutting plate 3, thereby providing a limiting function for the flexible die-cutting plate 3 and preventing the flexible die-cutting plate 3 from shifting its position along the axis of the magnetic roller body 1 during operation. The limiting clips 301 on the bottom side of the flexible die-cutting plate 3 are equidistantly arranged, and two sets of annular limiting grooves 101 are symmetrically arranged on the outer side of the magnetic roller body 1. The limiting clips 301 are fitted and locked in the annular limiting grooves 101. The flexible die-cutting plate 3 is wrapped and attached to the outer cylindrical surface of the magnetic roller body 1 to form a cylindrical die-cutting plate. At the same time, the multiple limiting clips 301 on the bottom side of the flexible die-cutting plate 3 also form an annular locking member, which is locked in the annular limiting groove 101.

[0019] Example 2 Based on Example 1, please refer to Figures 4-6 In order to further improve the working stability of the cylindrical die-cutting plate by means of axial limiting through the engagement of the annular snap-fit ​​component with the annular limiting groove 101, the auxiliary components are set up to limit the axial positioning of the cylindrical die-cutting plate. An auxiliary groove 102 is provided on one side of the annular limiting groove 101. The auxiliary groove 102 is connected to the annular limiting groove 101 and is parallel to the axis of the magnetic roller body 1. The cylindrical die-cutting blade is assisted in limiting the direction of movement by the auxiliary components. That is, when the flexible die-cutting blade 3 is attached to the outer cylindrical surface of the magnetic roller body 1, the two ends of the flexible die-cutting blade 3 are in contact and attached when forming a cylindrical die-cutting blade. During this process, it is necessary to align the contact and attachment positions of the two ends of the flexible die-cutting blade 3 with the auxiliary groove 102. That is, when the limiting clips 301 near the two ends of the flexible die-cutting blade 3 are connected, the connection position of the two limiting clips 301 is aligned with the auxiliary groove 102, which facilitates the subsequent installation and use of the auxiliary components.

[0020] Then according to the appendix Figure 6 As shown, the auxiliary components include a positioning groove 401 and a concave rubber strip 402. A positioning groove 401 is provided on one side of the limiting body 301 near the end of the flexible die-cutting plate 3. That is, when the flexible die-cutting plate 3 is attached to the outer surface of the magnetic roller body 1, the positioning groove 401 on the side wall of the limiting body 301 near the end of the flexible die-cutting plate 3 is positioned in the auxiliary groove 102. Then, the concave rubber strip 402 is used to position the positioning groove 401 on the side wall of the limiting body 301. The purpose of this snap-fit ​​operation is to provide stability at the joints of the two ends of the flexible die-cutting plate 3, that is, to prevent the joints from becoming loose when the flexible die-cutting plate 3 is working. Specifically, the operator uses their hand to squeeze the push-pull buckle 403 to push the concave rubber clip 402, so that the two ends of the concave rubber clip 402 are respectively snapped into the positioning grooves 401 on the side wall of the limiting clip body 301, until the concave rubber clip 402 is firmly locked into the positioning grooves 401 on the limiting clip body 301 at the joint position.

[0021] The purpose of providing an auxiliary groove 102 on the side of the annular limiting groove 101 on the outer surface of the magnetic roller body 1 is to facilitate the installation of auxiliary components. When engaging the concave rubber clip 402 with the positioning groove 401 on the side wall of the limiting clip 301, the concave rubber clip 402 is placed into the auxiliary groove 102, and then moved until the end of the concave rubber clip 402 is aligned with the positioning groove 401. Then, the concave rubber clip 402 is pushed by hand to lock the end of the concave rubber clip 402 into place with the positioning groove 401. The snap-fit ​​end of the concave rubber clip 402 reaches the groove position of the positioning slot 401. In this solution, a push-pull buckle 403 is also fixedly installed on the side wall of the concave rubber clip 402. The purpose of setting the push-pull buckle 403 here is to make it very convenient for the snap-fit ​​between the concave rubber clip 402 and the positioning slot 401, as well as the subsequent snap-fit ​​release between the concave rubber clip 402 and the positioning slot 401. That is, when separating the snap-fit ​​end of the concave rubber clip 402 from the positioning slot 401, simply pinch the push-pull buckle 403 by hand to pull the snap-fit ​​end of the concave rubber clip 402 out of the positioning slot 401.

[0022] When replacing the flexible die-cutting blade 3 during subsequent use, it is necessary to first release the auxiliary limiting effect of the auxiliary components on the flexible die-cutting blade 3. That is, first release the engagement between the concave rubber clip 402 and the positioning groove 401 on the side wall of the limiting clip 301. The operator needs to use their hand to squeeze the push-pull buckle 403 and pull the concave rubber clip 402 outward until the engaging end of the concave rubber clip 402 separates from the positioning groove 401. The auxiliary limiting effect of the flexible die-cutting blade 3 is then released. At this time, the mating positions at both ends of the flexible die-cutting blade 3 are separated from the auxiliary groove 102. Finally, the limiting clips 301 set on the bottom side of the flexible die-cutting blade 3 are separated one by one from the annular limiting groove 101. The disassembly of the flexible die-cutting blade 3 can be completed quickly. While ensuring the stable use of the flexible die-cutting blade 3, its installation and subsequent disassembly and maintenance are also very convenient.
