Description

Technical Field

[0001] The invention relates to the technical field of lamp pole processing, and in particular to a lamp pole self-dipping anti-corrosion coating production line. Background Art

[0002] As an outdoor facility, the most basic requirement for light poles is that they can resist corrosion and oxidation for a long time. The quality of corrosion resistance is related to the service life and aesthetics of the light poles. Therefore, it is necessary to select reliable quality substrates, surface treatment processes and coating processes when producing light poles. Regarding the coating process, electrostatic powder spraying cannot effectively coat the inner cavity of the light pole, and other traditional coating processes such as fluidized bed, plastic dipping, dip varnishing and electrophoretic coating cannot meet the requirements due to various limitations.

[0003] Self-swimming paint technology is a new type of coating technology. The basic principle is to immerse the workpiece in the self-swimming paint and use the characteristics of the paint itself to form a uniform and dense coating. The characteristics of self-swimming paint technology are as follows: Self-leveling: The paint can automatically level to form a smooth surface, avoiding brush marks or uneven spraying that may occur in traditional painting; High adhesion: can ensure good bonding between the coating and the substrate, and improve the wear resistance and corrosion resistance of the coating; Environmental protection: Many self-swimming paints use water-based paints, which reduces the use of organic solvents and reduces environmental pollution; self-swimming paints can form a coating at room temperature, which is more environmentally friendly than high-temperature processes; Strong adaptability: Self-swimming paint can be applied to a variety of substrates, including metal, plastic, concrete, etc.; High efficiency: Self-coating paint can automatically adjust the coating thickness, reducing the need for multiple coatings and improving efficiency.

[0004] Therefore, this solution uses self-phoretic paint technology to effectively paint the inner cavity of the lamp pole, thereby improving the coating effect and overall corrosion resistance of the lamp pole. Summary of the invention

[0006] In order to achieve the purpose of the present invention, the following scheme is proposed: A lamp pole self-dipping anti-corrosion coating production line, comprising: Automated crane conveyor track, used for upper and lower parts of lamp poles, used to transfer the lamp poles to the following pools in sequence for corresponding treatment; Spray degreasing pool, used to spray degreasing liquid on the lamp pole, the degreasing liquid is 25℃-50℃; Immersion degreasing tank, filled with 45℃-55℃ degreasing liquid, used for dipping lamp poles; The first water washing tank is filled with tap water at room temperature and is used to immerse the lamp poles; The second washing tank is filled with tap water at room temperature and is used to immerse and spray the lamp poles simultaneously; Acid pickling tank, filled with 50℃-65℃ pickling liquid, used to immerse the lamp poles; The first neutralization tank is filled with neutralization liquid at room temperature and is used to immerse the lamp pole; The second neutralization tank is filled with neutralization liquid at room temperature and is used to immerse the lamp poles; The third water washing tank is filled with tap water at room temperature and is used to immerse the lamp poles; The first pure water tank is filled with pure water at room temperature and is used to immerse and spray the light poles at the same time; The second pure water tank is filled with pure water at room temperature and is used to immerse and spray the light poles at the same time; Self-swimming pool, filled with 20℃-25℃ self-swimming paint, used to dip the light poles so that the self-swimming paint is evenly applied to the inner and outer surfaces of the light poles; The third pure water tank is filled with pure water at room temperature and is used to immerse the lamp poles; Reaction water washing tank, filled with 50℃-65℃ water washing liquid, used to immerse the lamp poles; Oven, used to dry the lamp poles by circulating hot air, first at low temperature and then at high temperature.

DETAILED DESCRIPTION

[0010] like Figure 1 , Figure 3 As shown, this embodiment provides a lamp pole self-swimming anti-corrosion coating production line, including an automated driving conveyor track and multiple pools, the automated driving conveyor track is connected to a flying palladium 1, and two hooks 11 are suspended below the flying palladium 1 to hook the two ends of the lamp pole respectively. The automated driving conveyor track is used for the upper and lower parts of the lamp pole, and is used to transfer the lamp pole to the following pools in turn for corresponding treatment (all the bottom parts of the tanks are equipped with a circulation system-Venturi stirring nozzle (60 liters / min) to improve the fluidity of the tank liquid): The spray degreasing pool uses spraying to pre-degrease the lamp poles. The degreasing liquid consists of a degreasing agent, an activator and tap water. The degreasing liquid temperature is 25℃-50℃ and the spraying time is 1.5min-2min.

[0011] The immersion degreasing tank is filled with 45℃-55℃ degreasing liquid. The lamp pole is degreased for the second time by immersion, and the immersion time is 4min-6min.

[0012] The first washing pool is filled with tap water at room temperature, and the lamp poles are washed by immersion for 0.5min-1min to wash away the chemical reagents.

[0013] The second washing pool is filled with tap water at room temperature. The lamp poles are washed by immersion and spraying for 0.5min-1min to ensure that the residual concentration of chemical reagents on the surface of the lamp poles is less than 0.1%.

[0014] The pickling tank contains a 50℃-65℃ pickling solution. The lamp pole is pickled by immersion for 20 minutes to remove the rust and oxide scale on the surface of the lamp pole to ensure that the base material of the lamp pole is exposed. The pickling solution contains sulfuric acid, oxalic acid and water. In order to improve the pickling effect, two pickling tanks can be set.

[0015] The first neutralization tank is filled with room temperature neutralization liquid, which is used to remove the residual acid wash liquid on the lamp pole by immersion for 2 minutes. The neutralization liquid is composed of potassium hydroxide and water, and the concentration of the neutralization liquid in the first neutralization tank is 1%-2%.

[0016] The second neutralization tank is filled with room temperature neutralization liquid, which is used to remove the residual acid wash liquid on the lamp pole for a second time by dipping for 3-5 minutes to ensure that there is no acid residue. The concentration of the neutralization liquid in the first neutralization tank is 3%-6%.

[0017] The third washing pool is filled with tap water at room temperature, and the lamp poles are washed by immersion for 0.5min-1min to wash away the chemical reagents on the surface of the lamp poles.

[0018] The first pure water pool is filled with pure water at room temperature. The lamp poles are washed by immersion and spraying for 0.5min-1min. The conductivity of the pure water outlet is ≤10μs / cm.

[0019] The second pure water pool is filled with pure water at room temperature, and the lamp poles are washed by immersion and spraying for 0.5min-1min.

[0020] Two pure water washes have the following effects: ① Remove impurity ions: Remove impurity ions on the surface of the lamp pole to prevent these ions from contaminating the self-dipping paint tank liquid. This is very important to ensure the cleanliness and stability of the self-dipping paint tank liquid, because any impurities may affect the film-forming quality and effect of the self-dipping paint; ② Improve coating efficiency: Pure water washing can reduce impurities in the self-dipping paint tank, thereby improving coating efficiency and reducing the failure rate during the coating process, which has a positive effect on improving production efficiency and reducing costs.

[0021] The self-swimming pool is filled with 20℃-25℃ self-swimming paint and is equipped with multiple agitators. The lamp poles are painted by dipping. After dipping for 3 minutes, the self-swimming paint can be evenly coated on the inner and outer surfaces of the lamp poles.

[0022] The third pure water pool is filled with pure water at room temperature and is equipped with multiple agitators. The lamp poles are washed by immersion for 0.5min-1.5min.

[0023] The third pure water pool function: ①Remove residues: Cleaning with pure water after autophoresis can remove residues on the surface of the lamp pole, including undeposited autophoresis paint and possible impurities, to ensure the cleanliness and uniformity of the coating; ② Improve coating quality: Pure water cleaning helps improve the quality of the coating because it can remove impurities that may affect the adhesion and durability of the coating, thereby improving the performance and anti-corrosion effect of the coating; ③Prevent pollution: Through pure water cleaning, impurities on the surface of the lamp pole can be prevented from contaminating subsequent process steps, which is crucial to maintaining the stability and reliability of the entire coating process.

[0024] The reaction washing tank is filled with 50℃-65℃ washing liquid and equipped with multiple stirrers. The lamp pole is washed by immersion for 1min-2min. The washing liquid is composed of fluorozirconic acid, inorganic alkali and water.

[0025] Function of reaction water washing tank: ① Neutralization: Reaction water washing can neutralize the coating formed by the self-exposing paint on the surface of the lamp pole, which helps to stabilize the chemical properties of the coating and prevent unnecessary chemical reactions during subsequent treatment; ② Improve corrosion resistance: The corrosion resistance of the coating can be further improved by reactive water washing. This step helps to remove residual substances that may affect the corrosion resistance of the coating, thereby ensuring the long-term stability and protective effect of the coating; ③ Clean the coating surface: Reaction water washing can remove the residues that may be produced during the autophoresis process, such as unreacted paint or other impurities, to ensure that the coating surface is clean, providing a good foundation for subsequent baking curing or powder spraying steps; ④ Promote coating curing: The reaction water wash may contain chemical components that promote the curing of the self-dipping paint coating, which helps the coating to cure better during the baking process and improve the hardness and durability of the coating.

[0026] ⑤ Environmental benefits: The reaction water washing step helps to reduce the emission of volatile organic compounds and toxic air pollutants.

[0027] Here we explain that the purpose of the water washing liquid at 50℃-65℃ is to allow the lamp pole to dry quickly after being taken out of the water, and to avoid cracking of the coating during baking.

[0028] The oven dries the lamp poles through hot air circulation, with the first 20 minutes at 90℃-120℃ low temperature drying and the next 20 minutes at 180℃-200℃ high temperature drying.

[0029] The lamp pole obtained by the above scheme has a uniform and dense coating formed on its inner and outer surfaces, and the coating is well bonded with the substrate.

[0030] Removing grease from the surface of the lamp pole is a very important step, which can not only improve the adhesion of the self-exposing paint, but also ensure the uniformity and durability of the coating. In the above scheme, the grease on the surface of the lamp pole is first removed by spraying and dipping in a degreasing liquid. Considering the poor fluidity of the liquid, especially the degreasing effect of the inner wall of the lamp pole needs to be improved, the present embodiment further provides a lamp pole inner wall scrubbing device in the dipping and degreasing pool for scrubbing the grease on the inner wall of the lamp pole. The specific implementation method is as follows: like Figure 2 , Figure 3 , Figure 5 , Figure 6 As shown, the device includes a first linear stroke component 2, a brush head 3, a collar 4, a guide plate 5 and two first telescopic components 6. The guide plate 5 is arranged in parallel with the first linear stroke component 2 in the immersion and degreasing tank, and both ends of the guide plate 5 and the first linear stroke component 2 are respectively connected to the two end surfaces of the immersion and degreasing tank, the collar 4 is slidably arranged along the guide plate 5, the first linear stroke component 2 is connected to the collar 4, and is used to move the collar 4 linearly and put the collar 4 outside the lamp pole. The first linear stroke component 2 can be realized by a motor-driven screw rod; the collar 4 and the top of the brush head 3 are both provided with a gap The mouth is used to avoid the hook 11; the two first telescopic components 6 are respectively arranged at the two ends of the immersion and degreasing pool, and the first telescopic components 6 can adopt a telescopic rod driven by a cylinder or an oil cylinder, one of the first telescopic components 6 is connected with a clamp 7, and the clamp 7 is used to clamp the brush head 3, and then the brush head 3 is inserted into the lamp pole under the action of the first telescopic component 6, and the other first telescopic component 6 is connected with a stopper 8. When the two first telescopic components 6 are extended to a preset length, the brush head 3 is inserted into the lamp pole, and at the same time, the clamp 7 and the stopper 8 respectively press against the two end faces of the lamp pole, thereby fixing the lamp pole.

[0031] The brush head 3 is cylindrical with a notch on the top. The curved outer wall array of the brush head 3 is provided with two rows of wheels. The function of the wheels is to facilitate the movement of the brush head 3 inside the lamp pole. The wheel material is made of non-metallic materials such as plastic. An iron block is provided inside the brush head 3, and a magnetic block is provided inside the ring 4. When the ring 4 is sleeved outside the lamp pole, it is used to absorb the brush head 3 inside the lamp pole and make the brush head 3 move in a straight line inside the lamp pole, thereby brushing the inner wall of the lamp pole and improving the grease removal effect on the inner wall of the lamp pole.

[0032] The arc-shaped outer wall of the brush head 3 is distributed with a layer of bristles in other areas except the wheel. The attached figure does not show the structure of the bristles. It should be noted that the bristles have a certain length, and the distance from the outermost edge of the bristles to the central axis of the brush head 3 is greater than the distance from the outermost edge of the wheel to the central axis of the brush head 3. For example, the distance between the outermost edge of the bristles and the outermost edge of the wheel is 5mm-10mm different. When the brush head 3 is inserted into the lamp pole, the two rows of wheels are close to the inner wall of the lamp pole, and the bristles are squeezed and deformed so as to be close to the inner wall of the lamp pole, so as to brush the inner wall of the lamp pole. In addition, bristles can also be set in the notch at the top of the brush head 3, which is conducive to more comprehensive brushing of the inner wall of the lamp pole. Even if bristles are set at the notch, when the brush head 3 is inserted into the lamp pole, the bristles at the notch can avoid the hook 11.

[0033] like Figure 4-Figure 6As shown, the clamp 7 includes a control box 71 and two clamps 72. One side of the control box 71 is connected to one of the first telescopic components 6, and the other side of the control box 71 is connected to the two clamps 72, which are used to control the distance between the two clamps 72. When the control box 71 and the stopper 8 abut against the end surface of the lamp pole, they are used to fix the lamp pole. A cylinder 32 is provided on one end surface of the brush head 3. The diameter of the cylinder 32 is smaller than the diameter of the brush head 3. Two grooves 33 are provided at the outer end of the cylinder 32 for matching the clamps 72. Both the cylinder 32 and the clamps 72 are made of non-metallic materials such as plastic.

[0034] Method of use: The immersion degreasing tank is pre-filled with degreasing liquid, and the lamp pole is transferred to the immersion degreasing tank by using the automatic driving conveyor track. The degreasing liquid submerges the lamp pole, and the lamp pole is located between the collar 4 and the block 8; the first linear stroke component 2 is located above the liquid level of the degreasing liquid, and the collar 4 is moved by the first linear stroke component 2, so that the collar 4 is sleeved outside the lamp pole and remains stationary (from Figure 6 The status changes to Figure 7 State), then the two first telescopic components 6 extend the preset length, so that the brush head 3 is inserted into the lamp pole, and the control box 71 and the stopper 8 respectively press against the two end faces of the lamp pole, so as to fix the lamp pole; because an iron block is provided in the brush head 3 and a magnetic block is provided in the collar 4, the collar 4 outside the lamp pole can absorb the brush head 3 in the lamp pole, and the clamping plate 72 releases the brush head 3, and the collar 4 is continued to be moved by the first linear stroke component 2, so that the brush head 3 can move linearly in the lamp pole, and the bristles on the brush head 3 scrub the grease on the inner wall of the lamp pole; after the collar 4 and the brush head 3 reach the other end of the lamp pole, they return, and when the brush head 3 returns to the hook 11, the clamping plate 72 is reinserted into the groove 33, and the clamping plate 72 clamps the brush head 3 again, and the brush head 3 is separated from the lamp pole under the action of the first telescopic component 6, and the collar 4 is separated from the lamp pole under the action of the first linear stroke component 2.

[0035] The connection method of the first linear travel component 2, the collar 4 and the guide plate 5 is as follows: Figure 6 As shown, the first linear travel component 2 is connected to the moving plate 21, the bottom of the moving plate 21 is connected to the slider 22, the outer wall of the collar 4 is provided with two transverse guide posts 41, both guide posts 41 slide through the slider 22, the outermost ends of the two guide posts 41 are connected together by a vertical plate, two vertical limit posts 42 are provided between the two guide posts 41, the guide plate 5 is located between the two limit posts 42, and the limit posts 42 are close to the guide plate 5. Figure 6 In the embodiment, the guide plate 5 is in a straight line, and the collar 4 and the brush head 3 are located on the same straight line, the collar 4 is waiting to be sleeved outside the lamp pole, and the brush head 3 is waiting to be inserted into the lamp pole.

[0036] This embodiment also provides another method, when the ring 4 and the brush head 3 are in the waiting stage, the ring 4 and the brush head 3 are not located in the same straight line, such as Figure 8-Figure 10As shown, the guide plate 5 is provided with an inclined plate 51 at one end facing the brush head 3, and an extension plate 52 is provided at the other end of the inclined plate 51. The guide plate 5, the inclined plate 51 and the extension plate 52 form a Z shape, and the two corners of the Z shape are both obtuse angles. The vertical distance between the extension plate 52 and the brush head 3 is greater than the vertical distance between the guide plate 5 and the brush head 3. Fig.10 In the state shown, the collar 4 and the brush head 3 are in a waiting stage, the limiting column 42 is close to the extension plate 52, and the collar 4 is located between the extension plate 52 and the first telescopic component 6; when the lamp pole is transferred to the immersion and degreasing pool, the first linear stroke component 2 is used to move the movable plate 21, the slider 22, the two guide columns 41 and the collar 4 along the extension plate 52. When the limiting column 42 moves from the inclined plate 51 to the guide plate 5, the collar 4 gradually moves between the brush head 3 and the lamp pole.

[0037] More specifically, in order to further improve the degreasing effect on the outer and inner walls of the lamp pole, the following measures can be taken: The first measure: two rows of wheels are also arranged on the arc-shaped inner wall of the collar 4, and the wheels are more conducive to the collar 4 moving along the outer wall of the lamp pole. A layer of bristles is distributed in other areas of the arc-shaped inner wall of the collar 4, which is used to brush the outer wall of the lamp pole. The bristles of the collar 4 have a certain length, and the distance from the innermost edge of the collar 4 bristles to the central axis of the collar 4 is less than the distance from the innermost edge of the wheel to the central axis of the collar 4. For example, the distance between the innermost edge of the bristles and the innermost edge of the wheel is 5mm-10mm different. When the collar 4 is put on the outside of the lamp pole, the two rows of wheels are close to the outer wall of the lamp pole, and the bristles are squeezed and deformed so as to be close to the outer wall of the lamp pole, so as to brush the outer wall of the lamp pole. In addition, bristles can also be set in the notch at the top of the collar 4, which is conducive to more comprehensive brushing of the outer wall of the lamp pole. Even if bristles are set at the notch, when the collar 4 is put on the outside of the lamp pole, the bristles at the notch can avoid the hook 11.

[0038] The second measure: Fig.11 As shown, the device also includes two groups of symmetrically arranged flipping components 9, each flipping component 9 includes a turntable 91, a rack 92 and a second telescopic component 93, the turntable 91 is rotatably connected to the end face of the immersion and degreasing tank, and an avoidance groove 911 is provided in the center of the turntable 91 for avoiding the first telescopic component 6. A plurality of saw teeth 912 are arrayed on the top of the turntable 91, and the rack 92 is engaged with the saw teeth 912. The second telescopic component 93 is arranged on the top of the immersion and degreasing tank, and its movable end is connected to the rack 92. The second telescopic component 93 can adopt a telescopic rod driven by a cylinder or an oil cylinder. A reinforcement plate 94 is provided on the turntable 91, and both ends of the first linear stroke component 2 are respectively connected to the corresponding reinforcement plates 94, and the guide plate 5 and the extension plate 52 are connected to the corresponding turntable 91.

[0039] The method of use is as follows: the degreasing liquid is pre-filled in the immersion degreasing pool, and the lamp pole is transferred to the immersion degreasing pool by using the automated driving conveyor track, and the degreasing liquid submerges the lamp pole; the first linear stroke component 2 is used to move the collar 4, so that the collar 4 is sleeved outside the lamp pole and remains still, and then the two first telescopic components 6 are extended to a preset length, so that the brush head 3 is inserted into the lamp pole, and the control box 71 and the stopper 8 respectively press against the two end faces of the lamp pole, thereby fixing the lamp pole; the clamping plate 72 releases the brush head 3, and the first linear stroke component 2 is used to continue to move the collar 4, so that the brush head 3 moves linearly in the lamp pole, and the collar 4 bristles scrub the grease on the outer wall of the lamp pole, and the brush head 3 bristles scrub the grease on the inner wall of the lamp pole; After the collar 4 and the brush head 3 reach the other end of the lamp pole, before returning, the second telescopic component 93 is first used to horizontally move the rack 92 to cause the turntable 91 to rotate a certain angle, such as between 10° and 30°, so that the first linear stroke component 2, the guide plate 5 and the collar 4 are rotated by a corresponding angle as a whole. Because the collar 4 magnetically absorbs the brush head 3, the brush head 3 also rotates by a corresponding angle. Then the first linear stroke component 2 is used to return the collar 4. When the collar 4 and the brush head 3 are about to return to the hook 11, the turntable 91 rotates in the opposite direction by a certain angle and returns to the original state, ensuring that when the brush head 3 returns to the hook 11, the clamp 72 can be reinserted into the groove 33. In other words, the function of the flip component 9 is to make the path of the collar 4 and the brush head 3 to reach the other end of the lamp pole different from the return path, thereby improving the degreasing effect on the outer and inner walls of the lamp pole, which is conducive to improving the adhesion of the self-swimming paint on the surface of the lamp pole in the self-swimming pool, ensuring the uniformity and durability of the coating, and improving the overall corrosion resistance of the lamp pole.

[0040] The above embodiments are only used to illustrate the technical ideas and features of the present invention, and are not intended to be the only or limit the present invention. It should be understood by those skilled in the art that various changes or equivalent substitutions made to the present invention without departing from the scope of the present invention all fall within the scope of protection of the present invention.
