Description

Technical Field

[0001] This utility model belongs to the field of wood grain coating roller coating technology, and particularly relates to a water-based wood grain coating self-organizing film-forming roller coating device. Background Technology

[0002] Water-based wood grain coatings are increasingly widely used in furniture manufacturing, interior decoration, and building materials due to their low pollution and high safety characteristics. Water-based wood grain coatings can simulate the texture of natural wood through special processes, combining decorative and environmental protection, but they require higher precision and adaptability of construction equipment.

[0003] Existing roller coating equipment is not convenient for adjusting the temperature of the coating. In low-temperature environments, the viscosity of water-based coatings increases, leading to uneven coating and sagging. Moreover, the coatings in the entire coating tank are often heated, requiring a high temperature to maintain the coating temperature, which greatly increases energy consumption. Therefore, a self-organizing film-forming roller coating device for water-based wood grain coatings is needed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide a water-based wood grain coating self-organizing film-forming roller coating device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A water-based wood grain coating self-organizing film-forming roller coating device includes a workbench, a protective box on the top of the workbench, a roller coating assembly inside the protective box, a coating tank at the bottom of the workbench, a suction pump connected to one side of the bottom of the coating tank, and a connecting hose connected to one end of the suction pump.

[0007] The roller coating assembly includes a motor housing. Inside the motor housing, the output end of the motor is connected to a lead screw. A movable block is threaded to the outside of the lead screw. A connecting rod is welded to the bottom of the movable block. A connecting frame is connected to the bottom of the connecting rod. A storage box is welded to the bottom of one end of the connecting frame. A fixing plate is provided inside the storage box. A resistance wire is provided inside the fixing plate. An absorbent cotton is provided at the bottom of the fixing plate. A squeezing plate is provided at the bottom of the absorbent cotton. A rubber roller is movably connected to the bottom of the squeezing plate. A sponge roller is rotatably connected to the other end of the connecting frame.

[0008] A further technical solution is that a limiting groove is provided inside the protective box, and the two sides of the connecting frame are slidably connected to the limiting groove.

[0009] In a further technical solution, both ends of the rubber roller are rotatably connected to one end of the connecting frame, and the rubber roller is located in front of the sponge roller.

[0010] In a further technical solution, the top of the storage box is connected to one end of the connecting hose, and the connecting hose is connected to the protective box.

[0011] In a further technical solution, the extrusion plate is convex, the interior of the extrusion plate is hollow, and the top and bottom of the extrusion plate are mesh-like.

[0012] In a further technical solution, a conveyor belt is connected to the bottom of the protective box, the connecting rod is connected through the protective box, the protective box is hollow, and the protective box is located outside the lead screw.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention features a built-in resistance wire heater in the storage box, which can control the temperature of water-based coatings within the optimal film-forming temperature range. This solves the problem of uneven coating caused by increased coating viscosity in low-temperature winter environments, while also accelerating moisture evaporation and shortening drying time. By heating the coating in the storage box, there is no need to heat the entire coating tank, greatly reducing energy consumption during the heating process and thus lowering the coating cost of the substrate. Furthermore, since the capacity of the storage box is much smaller than that of the coating tank, the coating can be heated quickly, reducing the coating time of the substrate and greatly improving work efficiency.

[0015] This invention uses a motor-driven screw to move a movable block up and down, achieving precise height adjustment of the rubber roller and sponge roller. This allows for adaptation to substrates of varying thicknesses, significantly improving the equipment's applicability. The screw drive ensures constant pressure from the rubber roller and sponge roller on the substrate, enhancing coating thickness uniformity. The absorbent cotton stores the coating material, which is then uniformly released through the mesh structure of the convex extrusion plate. Combined with the shearing force generated by the rotation of the rubber roller, this induces the directional alignment of flaky pigments in the coating, forming a self-organized texture similar to natural wood rings. This eliminates the need for traditional roller engraving. The elastic contact between the rubber roller and sponge roller adapts to curved or irregularly shaped substrates, and different curvatures can be achieved by adjusting the screw stroke.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] like Figures 1-4 As shown, this utility model embodiment provides a water-based wood grain coating self-organizing film-forming roller coating device, including a workbench 1, a protective box 2 on the top of the workbench 1, a roller coating assembly 3 inside the protective box 2, a coating tank 4 at the bottom of the workbench 1, a suction pump 5 connected to one side of the bottom of the coating tank 4, and a connecting hose 6 connected to one end of the suction pump 5.

[0025] The roller coating assembly 3 includes a motor housing 301. Inside the motor housing 301, the output end of the motor is connected to a lead screw 302. The outer side of the lead screw 302 is connected to a movable block 303 by a thread. A connecting rod 304 is welded to the bottom of the movable block 303. A connecting frame 305 is connected to the bottom of the connecting rod 304. A storage box 306 is welded to the bottom of one end of the connecting frame 305. A fixing plate 307 is provided inside the storage box 306. A resistance wire 308 is provided inside the fixing plate 307. An absorbent cotton 309 is provided at the bottom of the fixing plate 307. A squeezing plate 310 is provided at the bottom of the absorbent cotton 309. A rubber roller 311 is movably connected to the bottom of the squeezing plate 310. A sponge roller 312 is rotatably connected to the other end of the connecting frame 305.

[0026] In this embodiment, the suction pump 5 is turned on, and the coating is delivered to the storage box 306 via the connecting hose 6. At the same time, according to the coating characteristics and ambient temperature, the resistance wire 308 is turned on by the controller to adjust the coating temperature in the storage box 305 to 25-35℃, reducing the coating viscosity and facilitating coating. After the substrate enters the protective box 2, the motor in the motor box 301 is started according to the substrate thickness. The motor drives the lead screw 302 to rotate, and the movable block 303 moves up and down along the thread of the lead screw 302. If the substrate thickness increases, the movable block 303 drives the roller coating assembly 3 to rise, and vice versa. The coating in the storage box 306 permeates into the absorbent cotton 309 for storage. Under the pressure of the rubber roller 311, the extrusion plate 310 evenly squeezes out the coating in the absorbent cotton 309. When the rubber roller 311 rotates, the coating adheres to the surface. Through contact and relative movement with the substrate, the coating is transferred to the surface of the substrate, completing the initial coating.

[0027] like Figure 2 , Figure 3 and Figure 4 As shown, specifically, both ends of the rubber roller 311 are rotatably connected to one end of the connecting frame 305, and the rubber roller 311 is located in front of the sponge roller 312;

[0028] The top of the storage box 306 is connected to one end of the connecting hose 6, and the connecting hose 6 is connected to the protective box 2.

[0029] The extrusion plate 310 is convex, the interior of the extrusion plate 310 is hollow, and the top and bottom of the extrusion plate 310 are mesh-like.

[0030] The bottom of the protective box 2 is connected to the conveyor belt 7, and the connecting rod 304 is connected to the protective box 2 through the connection. The protective box 2 is hollow and is located outside the lead screw 302.

[0031] In this embodiment, the connecting frame 305 slides within the protective box limiting groove 8 on both sides, ensuring stability and guidance during movement. This allows the rubber roller 311 and sponge roller 312 to be precisely adjusted to a suitable contact distance with the substrate surface. During the rotation of the rubber roller 311, a shearing force is applied to the wet coating. Under the action of the shearing force, the pigment particles in the coating are oriented to simulate the texture of wood grain. At the same time, the resistance wire 308 heats the coating to form a temperature gradient, accelerating solvent evaporation and promoting the self-assembly of pigment particles to form a microstructure similar to natural wood grain. The substrate continues to move forward and comes into contact with the sponge roller 312 behind it. The sponge roller 312 uses its own elasticity and porous structure to perform secondary extrusion on the coating, filling the unevenness of the substrate surface to make the coating more uniform. On the other hand, it further refines and enriches the wood grain effect through its surface texture imprint, while absorbing excess coating to prevent dripping.

[0032] The working principle of this utility model is as follows: First, the suction pump 5 is started, and the coating is transported to the storage box 306 through the connecting hose 6. At the same time, according to the characteristics of the coating and the ambient temperature, the resistance wire 308 is turned on by the controller to adjust the temperature of the coating in the storage box 305 to 25-35℃, reducing the viscosity of the coating and facilitating coating. Then, after the substrate enters the protective box 2, the motor in the motor box 301 is started according to the thickness of the substrate. The motor drives the lead screw 302 to rotate, and the movable block 303 moves up and down along the thread of the lead screw 302. If the thickness of the substrate increases, the movable block 303 drives the roller coating assembly 3 to rise, and vice versa. Finally, the extrusion plate 310 presses against the rubber roller 311. Under pressure, the coating in the absorbent cotton 309 is evenly extruded. When the rubber roller 311 rotates, the coating adheres to the surface. Through contact and relative movement with the substrate, the coating is transferred to the substrate surface, completing the initial coating. During the rotation of the rubber roller 311, shear force is applied to the wet coating. The pigment particles in the coating are oriented under the action of shear force, simulating the texture of wood grain. The sponge roller 312 uses its own elasticity and porous structure to perform secondary extrusion on the coating, filling the unevenness of the substrate surface to make the coating more uniform. On the other hand, through its surface texture imprint, it further refines and enriches the wood grain effect, while absorbing excess coating to avoid dripping.

[0033] 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 and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
