Description

Technical Field

[0001] The utility model relates to the technical field of laser engraving, in particular to a laser plate cylinder capable of adding engraved edges at the edges of patterns. Background Art

[0002] The prior art has the following deficiencies:

[0003] The existing laser plate cylinders can only print the same pattern. When printing different patterns, the whole set needs to be replaced, increasing the printing cost.

[0004] The existing laser edge-engraving process is affected by parameters such as the edge-engraving width, number of lines, angle, wall, etc. Due to the angle and the edge parameter of the concave-convex point shape in the process, when the pattern shape is the same as or close to the angle in the process, the edge engraving cannot be added or is uneven, which easily causes burrs at the local edge of the edge engraving or the edge is not smooth. Summary of the Invention

[0005] The purpose of the utility model is to overcome the defects of the above-mentioned prior art and provide a laser plate cylinder capable of adding engraved edges at the edges of patterns.

[0006] The purpose of the utility model can be realized by the following technical solutions:

[0007] A laser plate cylinder capable of adding engraved edges at the edges of patterns includes a roller body. The roller body has three layers, sequentially including a metal layer in the center, a connection layer outside the center layer, and an outermost surface layer. The surface layer is movably connected to the connection layer. Grooves are provided on both sides of the center layer of the roller body, and side covers are installed at the grooves. The surface layer is a copper-plated layer, and dot areas are evenly distributed on the copper-plated layer. Dots are closely arranged in the dot areas, and the screen angle of the dots located at the edges of the patterns is greater than the screen angle of the dots located inside the patterns. Compared with the prior art, the utility model solves the problem that the existing laser plate cylinders can only print the same pattern and need to be replaced as a whole when printing different patterns, increasing the printing cost. It also solves the problem that due to the angle and the edge parameter of the concave-convex point shape in the process, when the pattern shape is the same as or close to the angle in the process, the edge engraving cannot be added or is uneven, which easily causes burrs at the local edge of the edge engraving or the edge is not smooth. It can make the pattern edge engraving uniform during laser engraving and there is no burr phenomenon at the edge after printing, further improving the success rate of the plate cylinder and shortening the sample approval cycle of customers.

[0011] To further elaborate on the technical means and effects adopted by the present utility model to achieve the intended invention purpose, the exemplary embodiments will be described in detail herein, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation modes described in the following exemplary embodiments do not represent all implementation modes consistent with the present application. On the contrary, they are only examples of methods and systems consistent with some aspects of the present application as detailed in the appended claims.

[0012] The terms used in the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The singular forms "a", "the", and "said" used in the present application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term " / and / " used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0013] The present utility model includes a roller body 1. The roller body 1 has three layers, including a central metal layer in sequence, a connecting layer 3 outside the central layer 2, and an outermost surface layer 4. The surface layer 4 is movably connected to the connecting layer 3. Grooves are provided on both sides of the central layer 2 of the roller body 1, and side covers 6 are installed at the grooves. The surface layer 4 is a copper-plated layer, and dot areas 5 are evenly distributed on the copper-plated layer. Dots 5 are closely arranged in the dot areas 5. The net angle of the dots 5 at the edge of the pattern is greater than the net angle of the dots 5 inside the pattern. The net angle of the dots 5 at the edge of the pattern is 38°, and the net angle of the dots 5 inside the pattern is 30°. The cross-section of the dots 5 inside the pattern is wavy, and the downward-sloping line of the wave shape is an arc, and the arc angle is 15°.

[0014] The present utility model solves the problem that the current laser plate cylinder can only print the same pattern and needs to be replaced as a whole when printing different patterns, increasing the printing cost. It also solves the problem that due to the parameters of angles and the shape of the concave and convex points at the edge in the process, when the pattern shape is the same as or close to the angle in the process, the edge engraving cannot be added or is uneven, which easily causes burrs or uneven edges at the local edge engraving. It can make the pattern have uniform edge engraving during laser engraving and no burrs at the edge after printing, further improving the success rate of the plate cylinder and shortening the customer's sample approval cycle.
