DETAILED DESCRIPTION

[0027] The present invention will be further described below in conjunction with the embodiments, but they are not intended to limit the present invention.

[0028] Example:

[0029] A floor surface treatment process with a three-dimensional pattern comprises the following steps:

[0030] S1. Apply a waterproof coating on the back of the floor to make the floor waterproof and prevent water vapor from affecting the floor pattern; polish the front of the floor substrate to make it smooth; before carving the floor, the present invention first polishes the floor to keep it smooth, and then carves on this basis to ensure the overall smoothness and accuracy of the pattern.

[0031] S2. Print the floor pattern plane on the surface of the coating plate to obtain a coating plate with a pattern. Set different colors of paint on different textures of the coating plate according to the engraving depth of different patterns, and then emboss on the floor surface to form a flat texture pattern with different colors. The present invention first uses different colors of paint to prime the floor, quickly determines the pattern texture and the depth of different textures, so as to facilitate subsequent rapid engraving and milling.

[0032] S3. Use a milling device to carve and mill different depths corresponding to different colors on the front of the floor to form a concave and convex three-dimensional pattern; when carving, carve along the paint texture to reduce carving errors, and according to different colors corresponding to different carving depths, different depth dimensions are preset in the milling device for automatic engraving, which can effectively ensure the integrity of the carving and avoid excessive damage to the floor.

[0033] S4. Use a milling device to perform milling on the side of the floor to form a mortise and tenon;

[0034] The present invention adopts a milling device to process the front and side of the floor respectively, carving a three-dimensional pattern on the front of the floor and the mortise and tenon on the side of the floor, splicing the floors with each other through the mortise and tenon, combining a variety of different patterns to form a unique customized visual effect.

[0035] S5. The raised and recessed parts of the three-dimensional pattern are first polished to remove burrs, and then the color coating, UV paint layer, fireproof coating and anti-corrosion coating are sequentially applied to the surface of the three-dimensional pattern of the floor. The UV paint layer, fireproof coating and anti-corrosion coating are used to protect the pattern and improve its durability.

[0036] After the UV paint layer is applied and before the UV paint layer is completely cured, a roller engraved with a three-dimensional concave-convex pattern of the floor is used to press the three-dimensional pattern under a certain pressure, and the depth of the concave-convex pattern of the roller is different, so that the floor surface forms a surface with different depths and brightness, and then the UV paint layer is cured. Since the UV paint layer has not yet been cured during pressing, the pressing will cause the UV paint layer to be squeezed, resulting in different depths on the floor surface. The thickness of the UV paint layer is thinner and the color is lighter at the location where the floor is pressed deeply, and the UV paint layer is thicker and the color is darker at the location where the floor is pressed shallowly, thereby causing a brightness deviation of the floor and forming a special appearance.

[0037] like Figure 1-Figure 4 As shown, the milling device in step S3 and step S4 includes a workbench 1, on which is provided an operating table 11, on which is rotatably connected a rotating table 12 driven by a rotating assembly, on which the rotating table 12 is used to place a floor, on which are symmetrically provided brackets 2 on both sides of the operating table 11, on which are provided a side processing mechanism 3 that moves up and down, the side processing mechanism 3 includes a driving cylinder 31, on which is provided a first mounting seat 32 on the driving shaft of the driving cylinder 31, in which a lateral tool 33 facing the side of the rotating table 12 in multiple directions is adsorbed by a first electromagnetic component; between the two brackets 2, there is provided a connecting frame 21 that moves up and down, on which is provided a surface processing mechanism 4 that moves left and right driven by a horizontal linear module 22, the surface processing mechanism 4 includes a second mounting seat 41, in which a vertical tool 42 facing the top surface of the rotating table 12 in multiple directions is adsorbed by a second electromagnetic component. The structure of the lateral tool 33 is consistent with that of the vertical tool 42.

[0038] The present invention simultaneously installs a surface processing mechanism 4 and a side processing mechanism 3 that can move up and down and left and right on the milling device, and places the floor on a rotatable rotating table 12, so as to facilitate multi-directional processing of the floor at different angles and different positions. The surface processing mechanism 4 is used to perform engraving and milling of the surface of the floor at different depths to form a concave and convex three-dimensional pattern; the side processing mechanism 3 is used to perform milling processing on the side of the floor to form the mortise and tenon of the floor. The milling device in the present invention integrates multiple processing procedures into one, thereby improving processing efficiency; wherein the side processing mechanism 3 includes a plurality of lateral cutters 33 installed on a first mounting seat 32, and the surface processing mechanism 4 includes a plurality of vertical cutters 42 installed on a second mounting seat 41. The first electromagnetic component and the second electromagnetic component are used to switch the lateral cutters 33 and the vertical cutters 42 to different magnetic pole directions to form a magnet effect of like poles repelling each other and opposite poles attracting each other, so that the tool switching work can be adjusted, and the rapid switching of different milling operations can be realized, so that when performing different engraving operations, different cutters do not need to be disassembled and reinstalled, saving operation steps and time.

[0039] The first electromagnetic assembly and the second electromagnetic assembly both include an electromagnetic component 34 and a magnet 35.

The vertical tool 42 is movably connected to the second mounting seat 41 through a flat key. The electromagnetic component 34 in the mounting seat and the magnet 35 on the tool correspond one to one. When the electromagnetic component 34 and the magnet 35 have different polarities and attract each other, the lateral tool 33 and the vertical tool 42 are respectively extended into the first mounting seat 32 and the second mounting seat 41; when the corresponding tool is needed for processing, the polarity of the electromagnetic component 34 corresponding to the magnet on the tool is changed to form a repulsion of the same polarity, and the tool is pushed out for processing, thereby realizing the switching processing of the tool.

The slider of the first longitudinal linear module 23 is fixedly connected to the driving cylinder 31, and the sliders on the two second longitudinal linear modules are fixedly connected to the connecting frame 21. Driven by the first longitudinal linear module 23, the side processing mechanism 3 moves up and down along the bracket 2, so as to process the side surfaces of the floor with different thicknesses. Driven by the second longitudinal linear module, the connecting frame 21 moves freely up and down along the bracket 2, so as to drive the surface processing mechanism 4 to move downward when working and contact the floor for surface engraving and milling, and move upward and separate from the floor when not working.

[0042] The second mounting seat 41 is also provided with a clamping column 43, and the bottom surface of the clamping column 43 is provided with a plurality of grooves 44, and the bottom of the groove 44 is connected with a double-layer positioning ball 46 through a compression spring 45, and a flow gap 461 is provided in the double-layer positioning ball 46, and a first dust suction hole 47 communicating with the flow gap 461 is provided at the bottom of the double-layer positioning ball 46, and a first dust suction pipe 48 communicating with the flow gap 461 is provided at the top of the double-layer positioning ball 46. The double-layer positioning ball 46 is a microstructure, which can be embedded in the concave part of the pattern during positioning, thereby improving the degree of positioning and clamping, ensuring that the floor position is not offset, and avoiding the destruction of the texture of the three-dimensional pattern, ensuring the integrity of the floor pattern; and a first dust suction hole 47 is provided on the double-layer positioning ball 46, and the first dust suction hole 47 is used to clean and remove wood chips in the dead corners of the concave corners and the fine corners, thereby improving the degree of cleaning of wood chips.
