Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of raw lacquer painting, and in particular to a raw lacquer painting structure for Phoebe shearera and a painting process thereof. BACKGROUND

[0002] Phoebe shearera, especially Phoebe shearera, is known as the "King of Wood" due to its unique texture, gorgeous golden luster, warm touch, and excellent corrosion and insect resistance. It is the top material for making high-end furniture, handicrafts, and ancient building restoration. In order to maximize its natural beauty and achieve long-term protection, traditional processes generally use natural raw lacquer for coating. The lacquer film formed by raw lacquer is hard, bright, wear-resistant, corrosion-resistant, heat-resistant, and insulating, and is environmentally friendly and non-toxic, which can perfectly blend with wood and remain new for a long time.

[0003] The existing surface painting of Phoebe shearera is mainly carried out by manual or mechanical painting, but there are the following shortcomings: It is difficult to ensure the uniformity of the lacquer film. The surface of Phoebe shearera has significant concave and convex fluctuations, and it is difficult to accurately control the supply amount of raw lacquer in different areas (concave and convex). Raw lacquer is prone to accumulate at the edge of the conduit due to high surface tension and poor flowability, resulting in local lacquer film being too thick. Insufficient paint on the convex part (wood rays / textures): when brushing, the bristles are in closer contact with the convex area, which may carry away excess raw lacquer, resulting in thinner lacquer film on the convex part, and even exposing the wood base.

[0004] To solve the above problems, we propose a raw lacquer painting structure for Phoebe shearera and a painting process thereof. SUMMARY

[0005] The purpose of the present application is to solve the problems in the background art and propose a raw lacquer painting structure for Phoebe shearera.

A brush head is connected to the lower end of the lacquer outlet pipe, and bristles are installed on the lower side wall of the brush head. A groove is formed on the lower side wall of the brush head, and a sliding rheostat is fixed in the groove. The sliding rheostat includes a slider, and a support rod is fixedly connected to the outer wall of the slider. An opening is formed at the lower end of the support rod, and a roller is installed in the opening. A sliding groove is formed on the lower side wall of the box, and an adjusting plate with a notch on its outer wall is slidably arranged in the sliding groove. The inner wall of the notch is fixedly connected to... A trapezoidal plate is connected to the outer bottom wall of the notch, and a telescopic spring is fixedly connected between the inner bottom wall of the notch and the outer bottom wall of the box. A squeezing port is opened on the outer wall of the paint outlet pipe, and a trapezoidal block is slidably arranged in the squeezing port. The trapezoidal plate is in contact with the inclined surface of the trapezoidal block. A magnet is fixedly embedded at the upper end of the trapezoidal plate. An electromagnet is fixed inside the box, located above the magnet and connected to a sliding rheostat and an external power supply through a wire. A capillary siphon layer is provided inside the paint outlet pipe. The capillary siphon layer is squeezed and released by moving the trapezoidal plate up and down to squeeze the trapezoidal block.

[0007] In the above-mentioned raw lacquer coating structure for Phoebe zhennan and Phoebe bournei, the trapezoidal plate has an opening, and the telescopic spring passes through the opening.

[0008] In the above-mentioned lacquer coating structure for Phoebe zhennan and Phoebe bournei, the reciprocating mechanism includes a guide rod fixed on the outer wall of the slider, the moving block is slidably sleeved on the outer wall of the guide rod, a motor is fixed on the lower side wall of the slider, a turntable is fixedly connected to the drive end of the motor, a connecting rod is rotatably connected to the lower side wall of the turntable off-center, and the other end of the connecting rod is rotatably connected to the upper side wall of the moving block.

[0009] In the above-mentioned raw lacquer coating structure for Phoebe zhennan and Phoebe bournei, the outer wall of the box body has a rectangular opening, the outer wall of the guide rod is fixedly connected to a horizontal plate, the outer wall of the horizontal plate is fixed with a right-angle plate, one end of the right-angle plate extends into the rectangular opening, and the outer wall is evenly distributed with serrations, the raw lacquer can is equipped with a rotating rod, the upper end of the rotating rod is fixed with a gear that meshes with the serrations, and the lower end of the rotating rod is fixed with a toggle plate located inside the raw lacquer can.

[0010] In the above-mentioned raw lacquer coating structure for Phoebe zhennan and Phoebe bournei, the outer walls of the lacquer outlet pipe and the trapezoidal block are both fixed with vertical plates, and a return spring is fixedly connected between the vertical plates.

[0011] In the above-mentioned raw lacquer coating structure for Phoebe zhennan and Phoebe bournei, the capillary siphon layer is composed of a sintered metal core and a cotton cloth layer wrapped around it.

[0012] In the above-mentioned raw lacquer coating structure for Phoebe zhennan and Phoebe bournei, a sliding gear switch connected to a motor is provided inside the box. The sliding gear switch includes a sliding handle, and a connecting arm is fixedly connected between the end of the sliding handle and the adjusting plate.

[0013] A lacquer application process for Phoebe zhennan (small-leaved Phoebe bournei) includes the following steps: S1. Use a bristle brush to remove all dust and sawdust from the surface of the wood; S2. Use high-grit sandpaper to sand gradually, starting from 240 grit and then sanding up to 320 grit, 400 grit, 600 grit, 800 grit and 1000 grit. S3. Place the treated wood on the painting table and hold it in place. S4. Select suitable raw lacquer and pour it into the raw lacquer container; S5. The cross slide moves along the wood grain with the brush head in an intermittent manner. After each unidirectional movement of the cross slide, the reciprocating mechanism is activated, so that the brush head 21 performs short-distance reciprocating varnishing at the current position, and performs multiple reciprocating varnishing operations on the wood surface. S6. When encountering a depression on the wood surface, the roller, support rod and slider slide down, the resistance in the electrical circuit connected to the electromagnet decreases, the current increases, the magnetism of the electromagnet increases, and the magnetic repulsion between the electromagnet and the magnetic block pushes the adjusting plate to move down. The trapezoidal plate squeezes the trapezoidal block to move into the paint tube, squeezing the capillary siphon layer, reducing the effective siphon aperture of the capillary siphon layer, reducing the amount of raw lacquer discharged, and avoiding the accumulation of raw lacquer in the depression. When encountering a protrusion on the wood surface, the trapezoidal block moves in the opposite direction, releasing the capillary siphon layer and increasing the amount of raw lacquer discharged. S7. After the paint film has fully cured, use 1200-grit or higher sandpaper dipped in paraffin oil as lubricant to gently sand along the grain, and then use polishing compound with a polishing machine for low-speed polishing.

[0014] Compared with existing technologies, the advantages of the raw lacquer coating structure used for this type of Phoebe zhennan and Phoebe bournei are: 1. A sliding resistor is set up, and the roller moves along the surface of the wood. The position of the roller changes according to the changes in the surface of the wood. The roller drives the slider of the sliding rheostat to slide. When the wood is concave, the slider moves down, the resistance in the electrical circuit connected to the electromagnet decreases, the current increases, and the magnetism of the electromagnet increases. The magnetic repulsion between the electromagnet and the magnetic block pushes the adjusting plate to move down. The trapezoidal plate squeezes the trapezoidal block to move into the paint tube, squeezing the capillary siphon layer and reducing the effective siphon aperture of the capillary siphon layer, reducing the amount of raw paint discharged and avoiding the accumulation of raw paint in the concave areas. Similarly, when the wood is convex, the capillary siphon layer loosens, the amount of raw paint discharged increases, and the entire surface of the convex area is evenly coated. 2. A sliding gear switch is set up. When the roller encounters a concave wood surface, the amount of raw lacquer discharged is reduced. To ensure a consistent lacquer film thickness, the adjusting plate moves the sliding handle via the sliding handle. The setting of the sliding gear switch increases, and the motor speed increases, allowing for multiple coats of lacquer to be applied to ensure the lacquer film thickness. When the roller encounters a convex wood surface, the amount of raw lacquer discharged increases, but the raw lacquer on the convex surface tends to flow downwards. When encountering a convex surface, the adjusting plate moves upwards, and the sliding handle moves the sliding handle via the sliding handle. The setting of the sliding gear switch decreases, and the motor speed decreases, allowing the bristles to move slowly along the convex surface. This allows the raw lacquer to have sufficient contact time with the convex surface, ensuring that the raw lacquer on the top is stably fixed and preventing the problem of an excessively thin lacquer film on the top caused by applying lacquer too quickly. In summary, this invention adjusts the application of lacquer according to the different texture defects encountered when applying lacquer to the surface of small-leaf Phoebe zhennan wood. When the wood surface is concave, the amount of lacquer applied is reduced to avoid lacquer accumulation, and multiple coats are applied to ensure the thickness of the lacquer film. When the wood surface is convex, the amount of lacquer applied is increased, but the brush movement speed is slowed down to allow the lacquer to fully contact and set with the surface, ensuring a uniform lacquer film thickness.

[0017] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0018] Reference Figures 1-8 A lacquer application structure for Phoebe zhennan (small-leaved Phoebe zhennan) includes an application table, a support plate 1 fixed on the application table, and a cross slide connected to the end of the support plate 1. The cross slide consists of two linear guide rails 2 and 3 arranged in a cross pattern. Each linear guide rail 3 includes a guide rail and a slider. A movable block 5 is connected to the slider, and a reciprocating mechanism is connected between the slider and the movable block 5. A housing 6 is fixed to the lower side wall of the movable block 5. The reciprocating mechanism includes a guide rod 4 fixed to the outer wall of the slider. The movable block 5 is slidably sleeved on the outer wall of the guide rod 4. A motor 7 is fixed to the lower side wall of the slider, and a turntable 8 is fixedly connected to the drive end of the motor 7. The lower side wall of the turntable 8 rotates off-center. A connecting rod 9 is connected, with the other end of the connecting rod 9 rotatably connected to the upper side wall of the moving block 5. The small-leaf Phoebe zhennan to be painted is placed on the painting table. The position of the brush head 21 and other components is adjusted by the cross slide, so that the brush bristles 22 can paint the small-leaf Phoebe zhennan. The cross slide drives the brush head 21 to move along the wood grain, moving intermittently, and the distance of each movement is the same as the range of the reciprocating movement of the moving block 5. After each movement, the motor 7 drives the turntable 8 to rotate, and one end of the connecting rod 9 moves in a circular motion with the turntable 8. The two ends of the connecting rod 9 pull the moving block 5 to slide back and forth on the outer wall of the guide rod 4. The brush bristles 22 contact the wood surface and apply raw lacquer to the wood surface. This process is repeated multiple times.

[0019] Furthermore, the painting table is also equipped with clamps for holding small-leaved Phoebe zhennan, such as quick clamps and vacuum suction cup clamps, which will not be described in detail here.

[0020] The outer wall of the box 6 has a rectangular opening 12. A horizontal plate 10 is fixedly connected to the outer wall of the guide rod 4. A right-angle plate 11 is fixed to the outer wall of the horizontal plate 10. One end of the right-angle plate 11 extends into the rectangular opening 12, and serrations are evenly distributed on its outer wall. A rotating rod 14 is installed on the raw lacquer tank 19. A gear 13 that meshes with the serrations is fixed to the upper end of the rotating rod 14. A deflector plate 15 located inside the raw lacquer tank 19 is fixed to the lower end of the rotating rod 14. The right-angle plate 11 is connected to the guide rod 4 and is in a fixed state. The reciprocating mechanism drives the moving block 5 and the box 6 to move back and forth. When the gear 13 moves along the serrations, it rotates itself, driving the rotating rod 14 and the deflector plate 15 to rotate back and forth. The deflector plate 15 deflects the raw lacquer to flow, promoting the flow of the raw lacquer and facilitating its discharge. When the temperature is low, a heating layer can also be set inside the raw lacquer tank 19. By deflecting the raw lacquer with the deflector plate 15, the temperature of the raw lacquer is made more uniform.

[0021] A raw lacquer tank 19 is installed inside the housing 6. A lacquer outlet pipe 20 is connected to the lower side wall of the raw lacquer tank 19. A brush head 21 is connected to the lower end of the lacquer outlet pipe 20. Brush bristles 22 are installed on the lower side wall of the brush head 21. A groove is formed on the lower side wall of the brush head 21. A sliding rheostat 16 is fixed in the groove. The sliding rheostat 16 includes a slider. A support rod 17 is fixedly connected to the outer wall of the slider. An opening is formed at the lower end of the support rod 17. A roller 18 is installed in the opening. A sliding groove is formed on the lower side wall of the housing 6. An adjusting plate 24 with a notch on its outer wall is slidably installed in the sliding groove. A trapezoidal plate 25 is fixedly connected to the inner wall of the notch. A telescopic spring 26 is fixedly connected between the bottom wall of the notch and the bottom wall of the housing 6. A through-hole is formed on the trapezoidal plate 25. The telescopic spring 26 passes through the through-hole. The outer wall of the paint outlet tube 20 is provided with a squeezing port. A trapezoidal block 28 is slidably arranged inside the squeezing port. The trapezoidal plate 25 is in contact with the inclined surface of the trapezoidal block 28. A magnet is fixedly embedded at the upper end of the trapezoidal plate 25. An electromagnet 23 is fixed inside the housing 6, located above the magnet and connected to the sliding rheostat 16 and an external power supply through wires. A capillary siphon layer is provided inside the paint outlet tube 20. The capillary siphon layer is composed of a sintered metal core and a cotton cloth layer. The pore size of the sintered metal core is 10-50μm. The capillary siphon layer is squeezed and released by the trapezoidal plate 25 moving up and down to squeeze the trapezoidal block 28. Vertical plates 27 are fixed on the outer walls of both the paint outlet tube 20 and the trapezoidal block 28. A return spring 29 is fixedly connected between the vertical plates 27. Roller 18 slides along the surface of the wood. After the cross slide moves and the brush head 21 stops, roller 18 adapts to the surface conditions at the contact point between the wood and roller 18. When the wood surface at the contact point is concave, the height of roller 18 decreases. Since lacquer tends to accumulate in concave areas, if the same amount of lacquer is used as on a flat surface, the brush bristles 22 cannot evenly apply the lacquer to the surface. Therefore, as roller 18 decreases in position, roller 18, support rod 17, and slide plate slide downwards. The resistance in the electrical circuit connected to electromagnet 23 decreases, the current increases, and the magnetism of electromagnet 23 increases. This is due to the magnetic relationship between electromagnet 23 and the magnet block. The repulsive force pushes the adjusting plate 24 downward, and the trapezoidal plate 25 squeezes the trapezoidal block 28 into the paint tube 20, squeezing the capillary siphon layer, reducing the effective siphon aperture of the capillary siphon layer, reducing the amount of raw lacquer discharged, and preventing raw lacquer accumulation in the recess. At the same time, the adjusting plate 24 drives the sliding handle to slide, the sliding position switch 30 increases the position, and the speed of the motor 7 increases. Because the capillary siphon layer is squeezed, the amount of raw lacquer discharged is reduced, but the thickness of the paint film needs to be uniform. Therefore, multiple brushing and painting are required in the recess, so that the raw lacquer discharged from the brush bristles 22 is applied to the inner wall of the recess, so that the paint film thickness of the entire surface of the wood is uniform. Similarly, when the wood surface protrudes at the contact position, the trapezoidal plate 25 moves upward. Under the reverse elastic force of the return spring 29, the trapezoidal block 28 moves to the outside of the paint tube 20, the capillary siphon layer is released, the effective siphon aperture of the capillary siphon layer is increased, the amount of raw lacquer discharged is increased, the surface area of ​​the protruding position is large, and the increased amount of raw lacquer discharged can ensure that the thickness of the paint film is consistent. There is no problem of paint film accumulation on the raised surface, and the raw paint flows easily, resulting in less raw paint on the top. Therefore, when the adjusting plate 24 moves, it drives the sliding handle to slide, the sliding position switch 30 decreases, the speed of the motor 7 slows down, and the bristles 22 move slowly along the raised surface, so that the raw paint can have sufficient contact time with the raised surface, and the amount of raw paint on the top of the raised surface can be consistent with other positions.

[0022] A sliding gear switch 30 connected to the motor 7 is installed inside the housing 6. The sliding gear switch 30 includes a sliding handle, and a connecting arm is fixedly connected between the end of the sliding handle and the adjusting plate 24.

[0023] A lacquer application process for Phoebe zhennan (small-leaved Phoebe bournei) includes the following steps: S1. Use a bristle brush to remove all dust and sawdust from the surface of the wood; S2. Use high-grit sandpaper to sand gradually, starting from 240 grit and then sanding up to 320 grit, 400 grit, 600 grit, 800 grit and 1000 grit. S3. Place the treated wood on the painting table and hold it in place. S4. Select suitable raw lacquer and pour it into the raw lacquer container 19; S5. The cross slide moves along the wood grain with the brush head 21 in an intermittent manner. After each unidirectional movement of the cross slide, the reciprocating mechanism is activated, so that the brush head 21 performs short-distance reciprocating painting at the current position, and performs multiple reciprocating painting work on the wood surface. S6. When encountering a depression on the wood surface, the roller 18, support rod 17 and slide plate slide downwards, the resistance in the electrical circuit connected to the electromagnet 23 decreases, the current increases, the magnetism of the electromagnet 23 increases, and the magnetic repulsion between the electromagnet 23 and the magnet pushes the adjusting plate 24 to move downwards. The trapezoidal plate 25 squeezes the trapezoidal block 28 into the paint tube 20, squeezing the capillary siphon layer, reducing the effective siphon aperture of the capillary siphon layer, reducing the amount of raw lacquer discharged, and avoiding the accumulation of raw lacquer in the depression. When encountering a protrusion on the wood surface, the trapezoidal block 28 moves in the opposite direction, releasing the capillary siphon layer and increasing the amount of raw lacquer discharged. S7. After the paint film has fully cured, use 1200-grit or higher sandpaper dipped in paraffin oil as lubricant to gently sand along the grain, and then use polishing compound with a polishing machine for low-speed polishing.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
