Description

Technical Field

[0001] This utility model relates to the field of rotary die-cutting technology, and in particular to a release paper slitting roller and a rolling cutting device. Background Technology

[0002] Existing release paper slitting roller blade adjustment structures, such as Figure 1 As shown, a blade pressure plate and a blade pad are required. The blade pad is located inside the blade, and the blade pressure plate is located outside the blade. Locking screws pass through the blade pressure plate and the blade pad in sequence to fix the blade to the roller body. There are many parts, the structure is complex, the required space is large, and the production cost is high. When the diameter of the release paper slitting roller is small, there is not enough space to set up a blade adjustment structure.

[0003] The existing technology has the following problems:

[0004] The existing release paper slitting roller blade adjustment structure has many parts, a complex structure, requires a large space, and has high production costs.

[0005] The above statements are for the purpose of providing background information in relation to this application only and do not necessarily constitute prior art. Utility Model Content

[0006] In view of the above problems, this application provides a release paper slitting roller and a rolling cutting device to solve the technical problems of existing release paper slitting roller blade adjustment structures having many parts, complex structure, large space requirements, and high production costs.

[0007] To achieve the above objectives, in a first aspect, this application provides a release paper slitting roller, including a roller body, a blade, an adjusting screw, a self-locking nut, and a locking screw;

[0008] The roller body is provided with a first mounting groove, a first screw hole, a blade groove, and a second screw hole. The first mounting groove is connected to the first screw hole, the first screw hole is connected to the blade groove, and the second screw hole is connected to the blade groove. The self-locking nut is disposed in the first mounting groove, the blade is disposed in the blade groove, the locking screw passes through the second screw hole to fix the blade in the blade groove, the adjusting screw passes through the first screw hole and contacts one end of the blade, and the self-locking nut passes through the adjusting screw to tighten the adjusting screw.

[0009] Unlike existing technologies, the technical solution of this application features a first mounting groove, a first screw hole, a blade groove, and a second screw hole on the roller body. The blade is positioned within the blade groove, and a locking screw passes through the second screw hole to fix the blade within the blade groove. An adjusting screw passes through the first screw hole and contacts one end of the blade. A self-locking nut is mounted on the adjusting screw. Thus, by rotating the adjusting screw, the blade moves within the blade groove, thereby adjusting the blade tip rotation diameter. The self-locking nut locks the adjusting screw, ensuring the relative position of the blade remains fixed. The locking screw secures the blade, preventing it from flying out during operation. The blade groove is directly formed on the roller body, eliminating the need for a blade pressure plate and blade pad. The locking screw does not need to pass through the blade pressure plate and blade pad to fix itself to the roller body, reducing the processing of the roller body. This results in a release paper slitting roller with a simple structure, convenient adjustment, small space requirement, and low production cost.

[0010] In one embodiment of this utility model, the roller body is further provided with a second mounting groove, which is connected to the second screw hole. The first screw hole extends along a first direction, and the second screw hole extends along a second direction. The first direction is perpendicular to the second direction.

[0011] Thus, the second mounting slot facilitates the installation of locking screws.

[0012] In one embodiment of the present invention, the roller body includes a first mounting part and a second mounting part. The first mounting part is disposed at the bottom of the first mounting groove, and the first screw hole is disposed on the first mounting part. The second mounting part is connected to the first mounting part and is disposed on one side of the blade groove. The second screw hole is disposed on the second mounting part.

[0013] Thus, the first screw hole passes through the first mounting part, and the second screw hole passes through the second mounting part, which facilitates the setting of the first screw hole and the second screw hole. The thickness of the first mounting part is greater than the thickness of the second mounting part, which can reduce the processing of the roller body and improve the stability of the roller body.

[0014] In one embodiment of this utility model, the first mounting part and the second mounting part are arranged perpendicularly.

[0015] This facilitates the setup of the first and second installation sections.

[0016] In one embodiment of this utility model, the adjusting screw is mounted on the roller body through the first mounting groove, the locking screw is mounted on the roller body through the second mounting groove, the adjusting screw is inside the outer circle of the roller body, and the locking screw is inside the outer circle of the roller body.

[0017] In this way, the outermost edge of both the adjusting screw and the locking screw is inside the outer circle of the roller body, preventing the adjusting screw from protruding from the roller body and affecting the slitting of the release paper.

[0018] In one embodiment of this utility model, the blade extends radially along the roller body, and the release paper slitting roller includes two or more adjusting screws, two or more self-locking nuts, and two or more locking screws. The roller body is provided with two or more first screw holes and two or more second screw holes radially. One first screw hole is provided with one adjusting screw and one self-locking nut, and one second screw hole is provided with one locking screw.

[0019] Thus, by setting two or more adjusting screws and two or more self-locking nuts on the radial direction of the blade groove of the roller body, rotating the adjusting screws can adjust the height of the blade in the radial direction of the roller body. By setting two or more locking screws on the radial direction of the blade groove of the roller body, rotating the locking screws can lock the blade in the radial direction of the roller body, preventing the blade from flying out during the working process.

[0020] In one embodiment of the present invention, the first mounting groove extends radially along the roller body, and two or more adjusting screws and two or more self-locking nuts are arranged sequentially in the first mounting groove; the second mounting groove extends radially along the roller body, and two or more locking screws are arranged sequentially in the second mounting groove.

[0021] Thus, the first mounting slot facilitates the installation of two or more adjusting screws and two or more self-locking nuts, while the second mounting slot facilitates the installation of two or more locking screws.

[0022] In one embodiment of this utility model, the cross-sectional shape of the blade groove is rectangular.

[0023] Thus, the cross-sectional shape of the blade groove is rectangular, and the cross-sectional shape of the blade is also rectangular, which facilitates the installation of the blade.

[0024] In one embodiment of this utility model, the blade and the roller are made of different materials.

[0025] Thus, the blade is made of mold steel, which has good wear resistance and red hardness after quenching, while the roller body is made of ordinary steel, which has good comprehensive mechanical properties such as strength and toughness after tempering. The blade and roller body are made of different materials, which can significantly reduce material costs.

[0026] To achieve the above objectives, in a second aspect, this application also provides a roll cutting apparatus, including a release paper slitting roller as described in any of the above claims.

[0027] Unlike existing technologies, the roll cutting device of this application directly forms the blade groove from the roller body, eliminating the blade pressure plate and blade pad. The locking screw does not need to pass through the blade pressure plate and blade pad to fix it to the roller body, reducing the processing of the roller body and making the release paper slitting roller simple in structure, easy to adjust, requiring little space and low in production cost.

[0028] The above description of the utility model is merely an overview of the technical solution of this application. In order to enable those skilled in the art to better understand the technical solution of this application and to implement it based on the description and drawings, and to make the above-mentioned objectives and other objectives, features and advantages of this application easier to understand, the following description is provided in conjunction with the specific embodiments and drawings of this application.

[0053] The existing release paper slitting roller blade adjustment structure has many parts, a complex structure, requires a large space, and has high production costs.

[0054] In view of this, this application provides a release paper slitting roller, including a roller body 1, a blade 2, an adjusting screw 3, a self-locking nut 4, and a locking screw 5; the roller body 1 is provided with a first mounting groove 11, a first screw hole 12, a blade groove 13, and a second screw hole 14. The first mounting groove 11 is connected to the first screw hole 12, the first screw hole 12 is connected to the blade groove 13, and the second screw hole 14 is connected to the blade groove 13. The self-locking nut 4 is disposed in the first mounting groove 11, the blade 2 is disposed in the blade groove 13, and the locking screw 5 passes through the second screw hole 14 to fix the blade 2 in the blade groove 13. The adjusting screw 3 passes through the first screw hole 12 and contacts one end of the blade 2. The self-locking nut 4 passes through the adjusting screw 3 and is used to tighten the adjusting screw 3. The blade groove 13 is directly formed by the roller body 1, eliminating the need for the blade pressure plate 20 and the blade pad 10. The locking screw 5 does not need to pass through the blade pressure plate 20 and the blade pad 10 to be fixed to the roller body 1, reducing the processing of the roller body 1. This makes the release paper slitting roller structure simple, easy to adjust, requires little space, and has low production cost.

[0055] According to some embodiments of this application, please refer to Figures 1 to 5 This embodiment relates to a release paper slitting roller, including a roller body 1, a blade 2, an adjusting screw 3, a self-locking nut 4, and a locking screw 5. The roller body 1 is provided with a first mounting groove 11, a first screw hole 12, a blade groove 13, and a second screw hole 14. The first mounting groove 11 is connected to the first screw hole 12, the first screw hole 12 is connected to the blade groove 13, and the second screw hole 14 is connected to the blade groove 13. The self-locking nut 4 is disposed in the first mounting groove 11, and the blade 2 is disposed in the blade groove 13. The locking screw 5 passes through the second screw hole 14 to fix the blade 2 in the blade groove 13. The adjusting screw 3 passes through the first screw hole 12 and contacts one end of the blade 2. The self-locking nut 4 passes through the adjusting screw 3 to tighten the adjusting screw 3 and prevent the adjusting screw 3 from rotating.

[0056] like Figure 1 As shown, in the prior art, the locking screw 5 needs to pass through the blade pressure plate 20, the blade pad 10, and engage with the threaded hole on the roller body 1 to fix the blade 2; in this embodiment, for example... Figure 4 As shown, the locking screw 5 passes through the second mounting part 17 to fix the blade 2, eliminating the need for the blade pressure plate 20, the blade pad 10, and the threaded holes on the roller body 1;

[0057] In this embodiment, the locking screw 5 passes through the second mounting part 17 and abuts against the left side of the blade 2, and the adjusting screw 3 passes through the first screw hole 12 and abuts against the top of the blade 2.

[0058] A first mounting groove 11 and a second mounting groove 15 are machined on the roller body 1. A hole is drilled and an internal thread is machined at the bottom of the first mounting groove 11 to form a first screw hole 12. A hole is drilled and an internal thread is machined on one side of the second mounting groove 15 to form a second screw hole 14. The second mounting part 17 is integrally formed with the roller body 1. A blade groove 13 is machined on the roller body 1.

[0059] In this embodiment, the structure and principle of the adjusting screw 3 and the self-locking nut 4 are conventional technical means, which will not be described in detail. The surface of the locking screw 5 is provided with external threads that are threaded to the second screw hole 14. The end of the locking screw 5 is provided with an internal hexagonal hole. The locking screw 5 and the locking blade 2 can be rotated by an internal hexagonal wrench.

[0060] In this embodiment, the roller body 1 is provided with a first mounting groove 11, a first screw hole 12, a blade groove 13 and a second screw hole 14. The blade 2 is placed in the blade groove 13. The locking screw 5 passes through the second screw hole 14 to fix the blade 2 in the blade groove 13. The adjusting screw 3 passes through the self-locking nut 4 and the first screw hole 12 and contacts one end of the blade 2.

[0061] Thus, by rotating the adjusting screw 3, the blade 2 moves within the blade groove 13, thereby adjusting the blade tip rotation diameter. The self-locking nut 4 is used to lock the adjusting screw 3, thereby fixing the relative position of the blade 2. The locking screw 5 locks the blade 2 to prevent it from flying out during operation. The blade groove 13 is directly formed by the roller body 1, eliminating the need for the blade pressure plate 20 and the blade pad 10. The locking screw 5 does not need to pass through the blade pressure plate 20 and the blade pad 10 to be fixed to the roller body 1, reducing the processing of the roller body 1. This makes the release paper slitting roller simple in structure, easy to adjust, requires little space, and has low production cost.

[0062] According to some embodiments of this application, optionally, such as Figure 5 As shown, the roller body 1 is also provided with a second mounting groove 15, which is connected to the second screw hole 14. The first screw hole 12 extends along the first direction (the direction indicated by arrow a in the figure), and the second screw hole 14 extends along the second direction (the direction indicated by arrow b in the figure). The first direction (the direction indicated by arrow a in the figure) is perpendicular to the second direction (the direction indicated by arrow b in the figure).

[0063] Thus, by providing a second mounting slot 15, it is convenient to install the locking screw 5.

[0064] According to some embodiments of this application, optionally, the roller body 1 includes a first mounting part 16 and a second mounting part 17. The first mounting part 16 is disposed at the bottom of the first mounting groove 11, and a first screw hole 12 is disposed on the first mounting part 16. The second mounting part 17 is connected to the first mounting part 16, and the second mounting part 17 is disposed on one side of the blade groove 13. A second screw hole 14 is disposed on the second mounting part 17.

[0065] The first mounting part 16 is integrally formed with the roller body 1, and the second mounting part 17 is integrally formed with the roller body 1;

[0066] Thus, the first screw hole 12 passes through the first mounting part 16, and the second screw hole 14 passes through the second mounting part 17, which facilitates the setting of the first screw hole 12 and the second screw hole 14. The thickness of the first mounting part 16 is greater than the thickness of the second mounting part 17, which can reduce the processing of the roller body 1 and improve the stability of the roller body 1.

[0067] According to some embodiments of this application, optionally, the first mounting portion 16 and the second mounting portion 17 are arranged perpendicularly.

[0068] This facilitates the installation of the first mounting section 16 and the second mounting section 17.

[0069] According to some embodiments of this application, optionally, such as Figure 4 As shown, the adjusting screw 3 is mounted on the roller body 1 through the first mounting groove 11, and the locking screw 5 is mounted on the roller body 1 through the second mounting groove 15. The adjusting screw 3 is inside the outer circle 18 of the roller body 1, and the locking screw 5 is inside the outer circle 18 of the roller body 1.

[0070] As described above, by reducing the blade pressure plate 20 and the blade pad 10, the space of the second mounting slot 15 can be reduced, and the space of the first mounting slot 11 can be increased, so that the adjusting screw 3 and the self-locking nut 4 can be installed in the first mounting slot 11.

[0071] Thus, the outermost edge of the adjusting screw 3 and the outermost edge of the locking screw 5 are both inside the outer circle 18 of the roller body 1, preventing the adjusting screw 3 from protruding out of the roller body 1 and affecting the slitting of the release paper.

[0072] According to some embodiments of this application, optionally, such as Figure 2 and Figure 3 As shown, the blade 2 extends radially along the roller body 1. The release paper slitting roller includes two or more adjusting screws 3, two or more self-locking nuts 4, and two or more locking screws 5. The roller body 1 is provided with two or more first screw holes 12 and two or more second screw holes 14 radially. One first screw hole 12 is provided with one adjusting screw 3 and one self-locking nut 4, and one second screw hole 14 is provided with one locking screw 5.

[0073] Thus, by setting two or more adjusting screws 3 and two or more self-locking nuts 4 in the radial direction of the blade groove 13 of the roller body 1, rotating the adjusting screws 3 can adjust the height of the blade 2 in the radial direction of the roller body 1. By setting two or more locking screws 5 in the radial direction of the blade groove 13 of the roller body 1, rotating the locking screws 5 can lock the blade 2 in the radial direction of the roller body 1, preventing the blade 2 from flying out during the working process.

[0074] According to some embodiments of this application, optionally, the first mounting groove 11 extends radially along the roller body 1, and two or more adjusting screws 3 and two or more self-locking nuts 4 are arranged sequentially in the first mounting groove 11; the second mounting groove 15 extends radially along the roller body 1, and two or more locking screws 5 are arranged sequentially in the second mounting groove 15.

[0075] Thus, the first mounting slot 11 facilitates the installation of two or more adjusting screws 3 and two or more self-locking nuts 4, and the second mounting slot 15 facilitates the installation of two or more locking screws 5.

[0076] According to some embodiments of this application, optionally, such as Figures 2 to 4 As shown, the cross-sectional shape of the blade groove 13 is rectangular.

[0077] The shape of the blade groove 13 matches the shape of the blade 2, and the cross-sectional shape of the blade 2 from the front projection angle is rectangular, such as... Figure 2 As shown, the cross-sectional shape of blade 2 from the side projection angle is also rectangular.

[0078] Thus, the cross-sectional shape of the blade groove 13 is rectangular, and the cross-sectional shape of the blade 2 is also rectangular, which facilitates the installation of the blade 2.

[0079] According to some embodiments of this application, optionally, the blade 2 and the roller 1 are made of different materials.

[0080] Thus, blade 2 is made of mold steel, which has good wear resistance and red hardness after quenching, while roller body 1 is made of ordinary steel, which has good comprehensive mechanical properties such as strength and toughness after tempering. Blade 2 and roller body 1 are made of different materials, which can significantly reduce material costs.

[0081] This embodiment also relates to a roll cutting device, including a release paper slitting roller as described in any of the above.

[0082] The roll cutting device also includes a frame and anvil rollers, with the anvil rollers and release paper slitting rollers mounted on the frame;

[0083] Unlike existing technologies, the roll cutting device of this application directly forms the blade groove 13 from the roller body 1, eliminating the blade pressure plate 20 and blade pad 10. The locking screw 5 does not need to pass through the blade pressure plate 20 and blade pad 10 to fix to the roller body 1, reducing the processing of the roller body 1. This makes the release paper slitting roller structure simple, easy to adjust, requires little space, and has low production cost.
