[0002] In order to improve the aesthetics, mildew resistance, corrosion resistance and waterproof performance of bamboo and wood boards, carbonization or surface coating will be performed. Photocatalytically active materials, such as titanium dioxide, produce strong oxidizing hydroxyl radicals and superoxide radicals under ultraviolet or visible light irradiation, which can destroy the cell membrane and genetic material of bacteria and viruses, and achieve efficient sterilization. In the prior art, a variety of methods for applying photocatalytically active materials to the surface of the board have been proposed, such as the Chinese invention patent with announcement number CN118832947B, a photocatalytic purification diatomite functional decorative board and its preparation method, which provides a diatomite substrate and polishes the surface with sandpaper; uniformly coats a layer of heat-sensitive epoxy resin adhesive on the diatomite substrate; lays a carbon fiber mesh on the uncured heat-sensitive epoxy resin layer, and then spreads titanium dioxide / paraffin / alumina composite particles, compacts with a roller, and accelerates curing with an oven; the board is coated with UV curing resin as a weather-resistant protective layer and cured with a UV lamp. The present invention significantly improves the composite particle distribution and fixation of the diatomite board by using carbon fiber mesh and heat-sensitive epoxy resin adhesive, and enhances the mechanical strength and photocatalytic efficiency. The carbon fiber mesh and aluminum oxide in the structure increase the wear resistance, optimize the titanium dioxide distribution, and improve the air purification efficiency and thermal stability.

[0003] In the prior art, there are many technical solutions for coating the surface of recycled boards and inorganic boards with photocatalytic active materials, but there are few studies on equipment for applying photocatalytic active materials to the surface of bamboo and wood boards.

In this process, the two telescopic longitudinal beams are stretched, and the piston rods of the four push cylinders contract synchronously to erect the two arms inwards, and raise the height of the two telescopic longitudinal beams. In this process, the two telescopic longitudinal beams are compressed, and the tensioning component keeps the two synchronous belts in a tensioned state, and the driving direction is diverse.

[0011] Preferably, it also includes two collecting troughs, two blanking ports, two collecting buckets and two exhaust pipes.

Since the two synchronous belts drive the two collecting buckets and the two mounting frames to move synchronously, the part where the two drop-out ports intersect with the multiple through holes of the two collecting buckets always follows the movement of the particle tank unit and the particle spray gun, so that the particles of excess photocatalytically active material that are not embedded on the surface of the bamboo and wood board are timely absorbed into the two collecting buckets, thereby realizing efficient recovery of the particles of excess photocatalytically active material that are not embedded on the surface of the bamboo and wood board.

The present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0019] Embodiment 1, as Figures 1 to 6As shown, a device for applying photocatalytic active material to the surface of a bamboo or wood board comprises a base plate 1; further comprising a driving mechanism 2, two clamping plates 3, two mounting frames 4, a sliding mechanism 5, a workbench 6, a particle tank unit 7, a particle spray gun 8 and a spraying assembly, wherein the driving mechanism 2 is mounted on the base plate 1, the two clamping plates 3 are relatively mounted on the driving mechanism 2, the driving mechanism 2 drives the clamping plates 3 to be relatively close to clamp the bamboo or wood board, the two mounting frames 4 are relatively mounted on the driving mechanism 2, the driving mechanism 2 drives the two mounting frames 4 to move longitudinally, the sliding mechanism 5 is mounted on the two mounting frames 4, the sliding mechanism 5 drives the workbench 6 to move laterally, the particle tank unit 7 and the spraying assembly are mounted on the workbench 6, the interior of the particle tank unit 7 is filled with photocatalytic active material particles, the particle spray gun 8 is mounted at the output end of the particle tank unit 7, and the spraying assembly Used for applying liquefied photocatalytic active material to bamboo and wood boards; the spraying assembly includes a spray pot 9 and a spray head 10, the spray pot 9 is installed on a workbench 6, the spray pot 9 stores a photocatalytic active material solution inside, and the spray head 10 is installed at the output end of the spray pot 9; it also includes a spray pot 2 11, a spray head 2 12, an electrode 13 and an electrode 2 14, the spray pot 2 11 is installed on the workbench 6, the spray pot 2 11 stores a photocatalytic active material solution 2, the photocatalytic active material solution 2 is conductive, and the concentration of the photocatalytic active material solution 2 is less than the concentration of the photocatalytic active material solution stored inside the spray pot 9, the spray head 2 12 is installed at the output end of the spray pot 2 11, the spray head 2 12 is located in front of the spray head 10, the spray head 13 is installed on the spray head 10, and the electrode 2 14 is installed on the clamp 3.

[0020] During operation, the driving mechanism 2 drives the two clamping plates 3 to approach and clamp the bamboo and wood board, and the powder particles of the photocatalytically active material are filled in the particle tank unit 7. An accelerating mechanism for the photocatalytically active material is arranged inside the particle tank unit 7. The accelerating mechanism is a compressed air jet mechanism or a shot blasting mechanism. The accelerating mechanism accelerates the photocatalytically active material in the particle tank unit 7 and outputs it through the particle spray gun 8, so that the photocatalytically active material hits the surface of the bamboo and wood board at a high speed, so that micropores are generated on the surface of the bamboo and wood board, and the surface of the bamboo and wood board is rough, which is conducive to the subsequent application of liquefied photocatalytically active material. The speed and angle of the particle spray gun 8 outputting the photocatalytically active material particles are adjusted, so that the photocatalytically active material particles are obliquely injected into the gaps between the bamboo and wood fibers from the side, so that some of the photocatalytically active material particles can be embedded in the surface of the bamboo and wood board. The driving mechanism 2 drives the two mounting frames 4 to move longitudinally, and the slide mechanism 5 drives the workbench 6 to move horizontally. The material is used to perform a comprehensive impact treatment on the surface of the bamboo and wood board. After the impact treatment is completed, the spray component works to apply a solution or sol of photocatalytic active material to the surface of the bamboo and wood board. Since the surface of the bamboo and wood board is roughened before spraying, the firmness of the photocatalytic active material on the surface of the bamboo and wood board is improved. By inlaying particles of photocatalytic active material on the surface of the bamboo and wood board, a particle layer is formed inside the coating after the solution or sol of photocatalytic active material applied by the spray component is solidified. Since the titanium dioxide-based photocatalytic active material coating is usually transparent (for example, CY-CG coating and Jiupeng light self-cleaning coating are both water-based ceramic photocatalytic coatings made of composite ceramics and super-active titanium dioxide materials, they form a uniform nano-thin film on the coated surface with high transparency), and the particles of titanium dioxide photocatalytic active material have multiple reflective surfaces, the particles will show a flashing effect under light, thereby improving the aesthetics of the bamboo and wood board.

Compressed air or pressurization is input into the interior of the spray pot 9, so that the dispersion is sprayed out in a mist form through the spray head 10, thereby performing electrostatic spraying, so that the droplets of photocatalytic active material solution are evenly adsorbed onto the surface of the bamboo and wood board. The driving mechanism 2 drives the two mounting frames 4 to move longitudinally, and the slide mechanism 5 drives the workbench 6 to move laterally, so that the titanium dioxide dispersion is evenly sprayed onto the surface of the bamboo and wood board.

The lower parts of the two side plates 17 are vertical plates. The upper parts of the two side plates 17 are flat plates. The lower edges of the vertical plates of the two side plates 17 are rotatably connected to the left and right ends of the bottom plate 1 respectively. A wear-resistant seal is arranged between the lower edges of the vertical plates of the two particle tank units 7 and the bottom plate 1. Seal, one end of the multiple push cylinders 18 is rotatably connected to the bottom plate 1, and the other ends of the multiple push cylinders 18 are rotatably connected to the two side plates 17 respectively, and the multiple push cylinders 18 drive the vertical plates of the two side plates 17 to be laid flat or erected. When the vertical plates of the two side plates 17 are erected, the vertical plates of the two side plates 17 close the space between the left and right ends of the two fixed end plates 15, and the two side plates 17 cooperate to close the space above the two fixed end plates 15. A wear-resistant sealing strip is arranged between the two side plates 17 and the fixed end plates 15, and a wear-resistant sealing strip is arranged between the opposite sides of the two side plates 17.

[0023] After the surface of the bamboo and wood board is roughened by the impact of the photocatalytic active material particles, the driving mechanism 2 drives the two clamping plates 3 to clamp the bamboo and wood board and descend, and the multiple push cylinders 18 drive the two side panels 17 to flip inward respectively, so that the two vertical plates of the two side panels 17 respectively close the space between the left and right ends of the two fixed end panels 15, and at the same time, the flat plates of the two side panels 17 close the space above the two fixed end panels 15, so that the two fixed end panels 15 and the two side panels 17 form a sealed box, and the exhaust pipe 16 is connected to an external vacuum pump, and the vacuum pump extracts the air in the sealed box through the exhaust pipe 16. The low pressure state in the sealed box quickly discharges the air in the bamboo and wood board. At this time, the spray pot 9, the spray head 10, the spray pot 2 11 and the spray head 2 12 cooperate to spray the bamboo and wood board. Since the air on the surface of the bamboo and wood board is discharged, the photocatalytic active material solution is easier to fill into the pores on the surface of the bamboo and wood board, thereby improving the spraying firmness and penetration depth.

The double-headed push cylinder 22 is installed on the base plate 1. The two piston rods of the double-headed push cylinder 22 are respectively connected to the two longitudinal beams 21.

[0026] The two piston rods of the double-headed push cylinder 22 extend synchronously and push the two longitudinal beams 21 away from each other. The two piston rods of the double-headed push cylinder 22 contract synchronously and pull the two longitudinal beams 21 closer to each other, so that the two clamps 3 release or clamp the bamboo and wood boards, and drive the two synchronous belts 28 to rotate synchronously, so that the two synchronous belts 28 respectively drive the two mounting frames 4 to move forward and backward synchronously, so that the two mounting frames 4, the slide mechanism 5 and the workbench 6 move forward and backward to achieve roughening and spraying of the bamboo and wood boards.

In this process, the two telescopic longitudinal beams 27 are stretched, and the piston rods of the four push cylinders 24 contract synchronously to erect the two support arms 23 inward and raise the height of the two telescopic longitudinal beams 27. In this process, the two telescopic longitudinal beams 27 are compressed, and the tensioning assembly keeps the two synchronous belts 28 in a tensioned state, with various driving directions.

[0027] It also includes two collecting troughs 29, two material dropping ports 30, two collecting buckets 31 and two exhaust pipes 32. The two clamps 3 are respectively installed on the two telescopic longitudinal beams 27. The lower end surfaces of the two synchronous belts 28 are in friction contact with the lower end surfaces of the two clamps 3. The upper parts of the two clamps 3 are provided with collecting troughs 29. The bottoms of the two collecting troughs 29 are provided with a plurality of through holes arranged in a straight line. The two synchronous belts 28 are provided with material dropping ports 30. The two material dropping ports 30 are located below the two collecting troughs 29. The two collecting buckets 31 are respectively installed on the lower surfaces of the two synchronous belts 28. On the surface, the upper openings of the two collecting buckets 31 are respectively connected to the two material dropping ports 30, and the two collecting buckets 31 are both installed with exhaust pipes 32, and the two exhaust pipes 32 are connected to the interior of the two collecting buckets 31; it also includes two vertical partitions 33, the two vertical partitions 33 are respectively installed vertically in the two collecting buckets 31, the upper edges of the two vertical partitions 33 are respectively connected to the top walls of the two collecting buckets 31, and the lower edges of the two vertical partitions 33 are respectively provided with gaps with the bottoms of the two collecting buckets 31, and the two vertical partitions 33 are respectively located at the upper openings of the two collecting buckets 31 On the inner side, two air extraction pipes 32 are respectively located above the inner sides of the two collecting buckets 31, and the two air extraction pipes 32 are respectively higher than the lower edges of the two vertical partitions 33; it also includes two slide rails 34, two sliders 35 and four push blocks 36. The two telescopic longitudinal beams 27 are both equipped with slide rails 34, and the middle parts of the two clamps 3 are both equipped with sliders 35. The two clamps 3 are respectively slidably installed in the two push cylinders 24 through the two sliders 35. Two push blocks 36 are respectively installed on the two synchronous belts 28. The two push blocks 36 are respectively located on the front and rear sides of the two clamps 3. The four push blocks 36 are aligned with the two ends of the two sliders 35 respectively; it also includes four magnetic blocks 1 37, four magnetic blocks 2 38 and four magnetic blocks 39. The front and rear ends of the two collecting buckets 31 are equipped with magnetic blocks 1 37, and the two synchronous belts 28 are equipped with two magnetic blocks 2 38. The two magnetic blocks 2 38 are respectively located on the front and rear sides of the two blanking ports 30. The four magnetic blocks 2 38 are respectively used to absorb the four magnetic blocks 1 37. The two telescopic longitudinal beams 27 are equipped with magnetic blocks 39 at both ends, and the four magnetic blocks 39 are respectively used to absorb the four magnetic blocks 1 37.

[0028] When roughening and spraying the surface of the bamboo and wood board, the two collecting buckets 31 are respectively adsorbed on the four magnetic blocks 2 38 through the two magnetic blocks 1 37. At this time, the two synchronous belts 28 can drive the two collecting buckets 31 to move synchronously. The two exhaust pipes 2 32 are connected to the external exhaust fan. The exhaust fan extracts the air in the two collecting buckets 31 through the two exhaust pipes 2 32, so that the interior of the two collecting buckets 31 is negative pressure. When the particles of the photocatalytic active material are used to impact the surface of the bamboo and wood board for roughening, the excess particles of the photocatalytic active material not embedded on the surface of the bamboo and wood board are blown into the two clamps. After being collected in the two collecting grooves 29 of the board 3, they are sucked into the two collecting buckets 31 through multiple through holes and two drop-out ports 30 for collection. Since the two synchronous belts 28 drive the two collecting buckets 31 and the two mounting frames 4 to move synchronously, the intersection of the two drop-out ports 30 and the multiple through holes of the two collecting grooves 29 always follows the movement of the particle tank unit 7 and the particle spray gun 8, so that the particles of the excess photocatalytic active material not embedded on the surface of the bamboo and wood board are timely absorbed into the two collecting buckets 31, realizing the efficient recovery of the particles of the excess photocatalytic active material not embedded on the surface of the bamboo and wood board. The vertical partition 33 divides the interior of the two collecting buckets 31 into two parts, an inner part and an outer part, so that the interior of the two collecting buckets 31 forms a U-shaped channel, so as to prevent the particles of the excess photocatalytic active material not embedded on the surface of the bamboo and wood board from being sucked away by the two exhaust pipes 22, and at the same time, the bamboo and wood debris that are impacted are sucked away, so as to achieve the preliminary separation of the particles of the photocatalytic active material and the bamboo and wood debris. After the surface of the bamboo and wood board is sprayed, the two synchronous belts 28 rotate synchronously, and the two synchronous belts 28 drive the two collecting buckets 31 to move to one end of the two telescopic longitudinal beams 27, so that the two magnetic blocks on the two collecting buckets 31 are 37 is adsorbed onto the corresponding two magnetic blocks three 39, and at the same time, the four magnetic blocks two 38 are disconnected from the adsorption effect with the four magnetic blocks one 37. At this time, the two synchronous belts 28 continue to rotate and no longer drive the two collecting buckets 31 to move, so that the two push blocks 36 on the two synchronous belts 28 contact one end of the two sliders 35, and the two synchronous belts 28 continue to rotate, so that the two push blocks 36 push the two sliders 35 along the two slide rails 34, so that the two splints 3 move along the two telescopic longitudinal beams 27, thereby pushing the bamboo and wood boards out of the two telescopic longitudinal beams 27, and realizing the long-distance transportation of the bamboo and wood boards.

[0029] like Figures 1 to 11As shown, a bamboo and wood board surface application device of the present invention has a photocatalytic active material. When it is working, the driving mechanism 2 first drives the two clamping plates 3 to approach and clamp the bamboo and wood board, and the particle tank unit 7 is filled with powder particles of the photocatalytic active material. The particle tank unit 7 is provided with photocatalytic active material particles that are accelerated and then output through the particle spray gun 8, so that the photocatalytic active material particles hit the surface of the bamboo and wood board at high speed, so that micropores are generated on the surface of the bamboo and wood board, and the surface of the bamboo and wood board is rough, which is conducive to the subsequent application of liquefied photocatalytic active material. Then, the speed and angle of the particle spray gun 8 to output the photocatalytic active material particles are adjusted, so that the photocatalytic active material particles are obliquely injected into the gaps between the bamboo and wood fibers from the side, so that part of the photocatalytic active material particles are injected into the gaps between the bamboo and wood fibers from the side. The particles of active materials can be embedded in the surface of the bamboo and wood board, and then the driving mechanism 2 drives the two mounting frames 4 to move longitudinally, and the slide mechanism 5 drives the workbench 6 to move horizontally to perform a comprehensive impact treatment on the surface of the bamboo and wood board. The excess particles of photocatalytic active materials that are not embedded on the surface of the bamboo and wood board are blown into the two collecting grooves 29 of the two plywood 3 and then sucked into the two collecting buckets 31 through multiple through holes and two drop ports 30 for collection. After the impact treatment is completed, the spraying assembly works to apply a solution or sol of photocatalytic active materials to the surface of the bamboo and wood board. After the spraying is completed, the driving mechanism 2 transports the two plywood 3 backwards, and the two plywood 3 clamp the bamboo and wood board and transport it backwards, so that the bamboo and wood board can be calcined and solidified at high temperature.

[0030] The main functions achieved by the present invention are: 1. Roughen the surface of bamboo and wood boards before coating to improve the firmness of photocatalytic active materials; 2. A particle layer with multiple reflective surfaces is formed inside the coating, presenting different flashing effects and improving aesthetics; 3.

Through the front and back spraying of two solutions of different concentrations, the electrostatic spraying effect of bamboo and wood boards is achieved, and the spraying uniformity is improved; 5. It has an openable vacuum sealing box to quickly discharge the air in the bamboo and wood board, making it easier for the photocatalytic active material solution to fill the pores on the surface of the bamboo and wood board, thereby improving the spraying firmness and penetration depth.
