Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1 to 3 This utility model provides a three-dimensional wood grain molding device, including a worktable 1, support frames 2 at the four corners of the bottom of the worktable 1, a fixed frame 3 symmetrically movable in the middle of the worktable 1, a driving assembly 4 for driving the fixed frame 3 to move at the top of the worktable 1, an unwinding roller 5 and a letterpress roller 6 respectively on the top two sides of the fixed frame 3, a molding frame 7 at the top of the worktable 1, a glue injection assembly 8 at the top of the molding frame 7, an auxiliary molding assembly 9 at the bottom of the letterpress roller 6, and a curing assembly 10 on one side of the molding frame 7. The device works by drawing the substrate to one side of the molding frame 7. The material passes between the letterpress roller 6 and the rubber roller 92 in the auxiliary molding assembly 9, and is wound and guided to one side of the curing assembly 10. It is then wound and guided along the curing roller 102 to the next process, realizing the winding and conveying of the substrate on the outer circular wall of the unwinding roller 5. During the conveying process, the UV glue is evenly sprayed onto the surface of the substrate through the glue injection assembly 8. Then, through the pressing and cooperation of the letterpress roller 6 and the rubber roller 92, the wood grain texture structure of the outer circular wall of the letterpress roller 6 is pressed onto the surface of the substrate. Subsequently, the UV glue with the wood grain texture structure is cured by the UV curing lamp 104 in the curing assembly 10, which conveniently presses the wood grain texture structure onto the surface of the substrate.

[0019] like Figure 2 As shown, specifically, the drive assembly 4 includes drive plates 41 symmetrically arranged on the top of the workbench 1. The middle of the drive plates 41 on both sides is provided with lead screws 42 that are threadedly connected to the fixed frames 3 on both sides. One drive plate 41 is provided with a motor 43 whose output shaft is fixedly connected to the lead screw 42. The motor 43 drives the lead screw 42 to rotate synchronously, thereby causing the fixed frames 3 on both sides to move closer to each other or further away, so as to quickly fix the unwinding rollers 5 and letterpress rollers 6 of different sizes and specifications, and improve the practicality of the equipment.

[0020] Specifically, the top two ends of the fixed frame 3 are rotatably provided with positioning posts 15, and the middle of the unwinding roller 5 and the letterpress roller 6 are provided with through holes that are inserted into and cooperate with the positioning posts 15.

[0021] Specifically, the workbench 1 has guide grooves 11 on both sides of the drive plate 41, and guide rails 12 are provided on the inner wall of the guide grooves 11. The fixed frames 3 on both sides are slidably connected to the guide rails 12 through sliders 13. The fixed frames 3 move back and forth along the guide rails 12 on both sides through the sliders 13 to improve the stability of the equipment when adjusting the distance between the fixed frames 3 on both sides.

[0022] like Figure 3 As shown, specifically, the glue injection assembly 8 includes an installation slot 81 on the top of the molding frame 7, a glue injection frame 82 on the installation slot 81, a plurality of glue injection heads 83 on the bottom of the glue injection frame 82, a plurality of solenoid valves 84 connected to the top of the glue injection frame 82 and the glue injection heads 83, a glue tank 85 on the top of the molding frame 7, a glue pump 86 on one side of the glue tank 85, the glue tank 85 being connected to the input end of the glue pump 86 via a first pipe 87, and the output end of the glue pump 86 being connected to the plurality of solenoid valves 84 via a second pipe 88. By starting the glue pump 86, the UV glue in the glue tank 85 is delivered to the plurality of solenoid valves 84. The number of solenoid valves 84 opened is determined according to the width of the substrate, so as to deliver the UV glue to the corresponding number of glue injection heads 83, so that the glue injection heads 83 can be evenly sprayed onto the surface of the substrate conveyed at the bottom, avoiding material waste and reducing production costs.

[0023] Specifically, the molding frame 7 is provided with several guide rollers 14 in the middle, which facilitates further guidance of the wound substrate.

[0024] Specifically, the auxiliary molding assembly 9 includes guide grooves 91 symmetrically arranged on the inner wall of the molding frame 7, and a rubber roller 92 slidably arranged along the guide grooves 91 on both sides and the letterpress roller 6. The side wall of the molding frame 7 is symmetrically provided with electric cylinders 93 whose telescopic ends are fixedly connected to both ends of the rubber roller 92. By controlling the telescopic extension and retraction of the electric cylinders 93 on both sides, the rubber roller 92 is driven to rise and fall along the guide grooves 91, so as to conveniently adjust the distance between the letterpress roller 6 and the rubber roller 92 according to the thickness of the substrate, so as to facilitate the printing cooperation between the letterpress roller 6 and the rubber roller 92, and to imprint the wood grain texture structure on the outer surface of the letterpress roller 6 onto the surface of the substrate.

[0025] Specifically, the curing assembly 10 includes a curing frame 101 provided on one side of the molding frame 7. Several curing rollers 102 are rotatably provided on the top of the curing frame 101. A lamp holder 103 is provided at the bottom of the curing rollers 102 on the curing frame 101. An ultraviolet curing lamp 104 is provided in the middle of the lamp holder 103. As the substrate is further conveyed, the UV adhesive after printing will be cured by the ultraviolet curing lamp 104, so that the surface of the substrate has a three-dimensional wood grain shadow.

[0026] The working principle of this utility model is as follows: During the conveying process of the substrate, UV glue is evenly sprayed onto the surface of the substrate through several glue dispensing heads 83. Then, through the pressing and imprinting action of the letterpress roller 6 and the glue roller 92, the wood grain texture structure of the outer circular wall of the letterpress roller 6 is imprinted onto the surface of the substrate. Subsequently, the UV glue with the wood grain texture structure is cured by the UV curing lamp 104, which conveniently imprints the wood grain texture structure onto the surface of the substrate, giving the substrate a three-dimensional wood grain shadow.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
