Description

Technical Field

[0001] This invention relates to the field of flowerpot spray painting technology, specifically to a flowerpot spray painting process that produces a flowing paint spraying effect. Background Technology

[0002] Existing flowerpot painting processes typically involve placing the flowerpots on a conveyor belt and manually spraying them. Flowerpot painting usually results in a limited color palette. To achieve a flowing paint effect, the distance between the nozzle and the surface being sprayed is controlled to ensure the paint flow is perpendicular to the surface, and the spray gun's movement speed is kept uniform. However, ordinary spray painting often results in flowing paint, a defect caused by poor operator skill. This flowing paint is uncontrollable, unsightly, and cannot guarantee consistent color across all flowerpots. Patent CN 202799762 U discloses gradient-colored plastic flowerpots, controlling the gradient effect by adjusting the pot's wall thickness. However, this method is complex and adds extra weight to the pots, hindering production. Furthermore, existing painting processes usually require each coat to dry completely before applying the next, which is time-consuming. Therefore, there is a need to develop a flowerpot painting process that provides a good, consistent, time-saving, and labor-saving flowing paint effect. Summary of the Invention

[0003] To address the existing technical problems, this invention provides a flowerpot spraying process that achieves a flowing paint effect. By spraying different paints onto the flowerpot blank in a step-by-step manner, the flowing paint effect of the flowerpot is achieved, and the spraying effect has high consistency, saving time and effort.

[0004] The technical solution of this invention is: a flowerpot spraying process with a flowing paint spraying effect, comprising the following steps:

[0005] S1. Spray PP white primer. Use a hand spray gun connected to the PP white primer and air source. Adjust the PP white primer sprayed from the hand spray gun to a fan shape with a fan width of 15cm. Adjust the air pressure and paint output of the hand spray gun to the middle value, and the distance between the spray gun head and the flower pot blank is 15cm. The hand spray gun is perpendicular to the spraying surface of the flower pot blank and moves parallel and at a uniform speed. Spray paint from the outer bottom upwards until the mouth of the flower pot blank, and spray downwards 15cm from the inside of the mouth of the flower pot blank to complete the PP white primer spraying. Place the flower pot in a high-temperature oven and bake at 70℃ for 30-40 minutes.

[0006] S2. Spray water-based white paint. Use a hand spray gun connected to water-based white paint and air source. Adjust the width of the spray fan of the hand spray gun to 8cm. The sprayed water-based white paint should be in the form of aerosol. The distance between the spray gun head and the flower pot should be 15cm. The hand spray gun should be perpendicular to the spraying surface of the flower pot. Spray paint from the bottom to the top at a uniform speed until it reaches 1 / 2 of the pot body. This completes the spraying of water-based white paint. Immediately proceed to the step of spraying water-based blue paint.

[0007] S3. Spray water-based blue paint. Use a hand spray gun connected to the water-based blue paint and air source. Adjust the fan width of the spray gun to 15cm. Adjust the air pressure and paint output of the hand spray gun to the middle value. The spray gun head sprays a mist of water-based blue paint. The PP white primer or water-based white paint sprayed on the flower pot can be seen through the mist of blue paint on the surface of the flower pot. Spray the water-based blue paint from the inside of the flower pot to the outside. Spray 2-3 circles of water-based blue paint on the inside of the flower pot rim for even coloring. Spray 1 circle of water-based blue paint on the outside of the flower pot rim and then spray water-based blue paint downwards at a uniform speed until it reaches 2 / 3 of the pot body. The water-based blue paint spraying is completed. Immediately proceed to the step of spraying water-based clear topcoat.

[0008] S4. Spray water-based clear topcoat. Use a hand spray gun connected to the water-based clear topcoat and air source. Adjust the fan width of the spray gun to 8cm. The sprayed water-based clear topcoat should be in a mist form. The distance between the spray gun head and the flowerpot should be 15cm. The hand spray gun should be perpendicular to the spraying surface of the flowerpot. Spray the paint from top to bottom at a uniform speed, starting from the outside of the flowerpot opening and spraying to 2 / 3 of the pot body. Then spray 2-3 circles of water-based clear topcoat along the 2 / 3 of the pot body to create a wave-like effect. After completing the water-based clear topcoat spraying, immediately place the flowerpot in a high-temperature oven and bake at 70℃ for 30-40 minutes.

[0009] S5. Spray high-gloss paint. Use a hand spray gun connected to the high-gloss paint and air source. Adjust the width of the fan sprayed by the hand spray gun to 15cm. Adjust the air pressure and paint output of the hand spray gun to be greater than the middle value. Spray the outside of the flower pot and the area 15cm below the inside of the flower pot mouth at a uniform speed to complete the high-gloss paint spraying. Place the flower pot in a high-temperature oven and bake at 70℃ for 30-40 minutes.

[0010] S6. Apply water-based interior black paint. Using a thick sponge, apply water-based interior black paint evenly to the area below 10cm from the inside of the flowerpot rim to the bottom of the pot. Then place the flowerpot in a high-temperature oven and bake at 70℃ for 30-40 minutes. Finally, let it air dry indoors.

[0011] Furthermore, in step S2, after completing the spraying of water-based white paint, the step of starting to spray water-based blue paint within 10 seconds is completed; in step S3, after completing the spraying of water-based blue paint, the step of starting to spray water-based clear topcoat within 10 seconds is completed.

[0012] Furthermore, different hand spray guns are used in steps S2 to S4 respectively, and the three hand spray guns are connected to the corresponding paint and air sources before step S2 begins.

[0013] Furthermore, in step S2, water-based white paint is sprayed around the outer circumference of the flowerpot.

[0014] Furthermore, the indoor drying time in step S6 shall not be less than 1 hour.

[0015] Before painting, the flowerpot blanks used in this invention need to have a smooth surface, no burrs at the rim, and no defects on the body. Through the process of this invention, the flowerpot produced exhibits a paint flow effect at 2 / 3 of the outer body. Step S2 achieves a white lower part of the paint flow effect, and step S3 achieves a blue upper part. The white portion remains pure white and clean, without any paint color or mist spots being sprayed onto the upper part of the paint flow effect.

[0016] By adopting the above technical solution, the beneficial effects achieved by the present invention are as follows:

[0017] (1) The present invention sprays PP white primer, water-based white paint, water-based blue paint, water-based clear topcoat, high-gloss paint and water-based interior black paint sequentially on the flowerpot blank, so that the flowerpot forms a paint flow effect at the outer 2 / 3 position of the pot body, and the color of each part of the flowerpot is clean and without residue, and the effect of each spraying is highly consistent.

[0018] (2) No drying is required between spraying water-based white paint, water-based blue paint and water-based clear topcoat, eliminating the step of high-temperature baking after spraying, and the overall process is time-saving and labor-saving. Attached Figure Description

[0021] The present invention will be further described in detail below with reference to specific embodiments.

[0022] Example 1

[0023] A flowerpot spray painting process with a flowing paint effect includes the following steps:

[0024] S1. Spray PP white primer. Use a hand spray gun connected to the PP white primer and air source. Adjust the PP white primer sprayed from the hand spray gun to a fan shape with a fan width of 15cm. Adjust the air pressure and paint output of the hand spray gun to the middle value, and the distance between the spray gun head and the flower pot blank is 15cm. The hand spray gun is perpendicular to the spraying surface of the flower pot blank and moves parallel and at a uniform speed. Spray paint from the outer bottom upwards until the mouth of the flower pot blank. Spray 15cm downwards from the inside of the mouth of the flower pot blank to complete the PP white primer spraying. Place the flower pot in a high-temperature oven and bake at 70℃ for 40 minutes.

[0025] When spraying PP white primer, the appropriate distance between the spray gun head and the flowerpot blank minimizes paint loss and prevents sagging.

[0026] The baking temperature is 70℃. If the temperature is higher than 70℃, it will cause the flowerpot blank to deform.

[0027] S2. Spray water-based white paint. Use a hand spray gun connected to water-based white paint and air source. Adjust the width of the spray fan of the hand spray gun to 8cm. The sprayed water-based white paint should be in the form of aerosol. The distance between the spray gun head and the flower pot should be 15cm. The hand spray gun should be perpendicular to the spraying surface of the flower pot. Spray paint from the bottom to the top at a uniform speed until it reaches 1 / 2 of the pot body. This completes the spraying of water-based white paint. Immediately proceed to the step of spraying water-based blue paint.

[0028] In step S1, the PP white primer is the base coat, and in step S2, the water-based white paint is the top coat.

[0029] S3. Spray water-based blue paint. Use a hand spray gun connected to the water-based blue paint and air source. Adjust the fan width of the spray gun to 15cm. Adjust the air pressure and paint output of the hand spray gun to the middle value. The spray gun head sprays a mist of water-based blue paint. The PP white primer or water-based white paint sprayed on the flower pot can be seen through the mist of blue paint on the surface of the flower pot. Spray the water-based blue paint from the inside of the flower pot to the outside. Spray 3 circles of water-based blue paint on the inside of the flower pot rim for even coloring. Spray 1 circle of water-based blue paint on the outside of the flower pot rim and then spray water-based blue paint downwards at a uniform speed until it reaches 2 / 3 of the pot body. The water-based blue paint spraying is completed. Immediately proceed to the step of spraying water-based clear topcoat.

[0030] During normal spray painting, the base color of the flowerpot should not be exposed, and the paint surface should be smooth and uniform. However, when spraying water-based blue paint in step S3, the water-based blue paint sprayed from the spray gun should be in the form of aerosol. White paint can be seen through the aerosol of water-based blue paint on the surface of the flowerpot, indicating that the paint output of the spray gun is smaller than that of normal spray painting, which is conducive to achieving the effect of flowing paint spraying.

[0031] S4. Spray water-based clear topcoat. Use a hand spray gun connected to the water-based clear topcoat and air source. Adjust the fan width of the spray gun to 8cm. The sprayed water-based clear topcoat should be in a mist form. The distance between the spray gun head and the flowerpot should be 15cm. The hand spray gun should be perpendicular to the spraying surface of the flowerpot. Spray the paint from top to bottom at a uniform speed. Spray from the outside of the flowerpot opening to 2 / 3 of the pot body. Then spray 3 circles of water-based clear topcoat along 2 / 3 of the pot body to create a wave effect. After completing the water-based clear topcoat spraying, immediately place the flowerpot in a high-temperature oven and bake at 70℃ for 40 minutes.

[0032] S5. Spray high-gloss paint. Use a hand spray gun connected to the high-gloss paint and air source. Adjust the width of the fan sprayed by the hand spray gun to 15cm. Adjust the air pressure and paint output of the hand spray gun to be greater than the middle value. Spray the outside of the flower pot and the area 15cm below the inside of the flower pot mouth at a uniform speed to complete the high-gloss paint spraying. Place the flower pot in a high-temperature oven and bake at 70℃ for 40 minutes.

[0033] When spraying high-gloss paint onto flower pots, you can spray from the inside out or from the outside in. Increase the air pressure and air volume of the spray gun to make the high-gloss paint spray more even, and the paint output from the spray gun head is greater than that of normal spraying, while controlling the paint flow to prevent paint drips.

[0034] S6. Apply water-based interior black paint. Using a thick sponge, apply water-based interior black paint evenly to the area below 10cm from the inside of the flowerpot rim to the bottom of the pot. Then place the flowerpot in a high-temperature oven and bake at 70℃ for 40 minutes. Finally, let it air dry indoors.

[0035] Use a thick sponge to apply water-based interior black paint to clean up any paint residue sprayed into the area below 10cm inside the flowerpot during steps S1-S5, ensuring the paint is applied evenly without gaps. Round off the area below 10cm inside the flowerpot rim with a thick sponge, ensuring no seams and avoiding wiping away any paint residue within the 10cm area. The indoor drying area must be clean, dust-free, and have clean air.

[0036] Furthermore, in step S2, after completing the spraying of water-based white paint, the step of starting to spray water-based blue paint within 10 seconds is completed; in step S3, after completing the spraying of water-based blue paint, the step of starting to spray water-based clear topcoat within 10 seconds is completed.

[0037] Furthermore, different hand spray guns are used in steps S2 to S4 respectively, and the three hand spray guns are connected to the corresponding paint and air sources before step S2 begins.

[0038] Furthermore, in step S2, water-based white paint is sprayed around the outer circumference of the flowerpot.

[0039] Furthermore, the indoor drying time in step S6 is 1 hour.

[0040] In step S3, the water-based blue paint can be replaced with other colors besides white, such as green.

[0041] Before painting, the flowerpot blanks used in this invention need to have a smooth surface, no burrs at the rim, and no defects on the body. Through the process of this invention, the flowerpot produced exhibits a paint flow effect at 2 / 3 of the outer body. Step S2 achieves a white lower part of the paint flow effect, and step S3 achieves a blue upper part. The white portion remains pure white and clean, without any paint color or mist spots being sprayed onto the upper part of the paint flow effect.

[0042] The flowerpot spray painting effect obtained in Example 1 is as follows: Figure 2 As shown, Figure 2It includes the blue part at the top, the flowing paint effect part in the middle, and the white part at the bottom. The blue part at the top has different shades, which is due to the light and shadow effect when the photo was taken and cannot be avoided. In reality, it is the same blue.
