Description

Technical Field

[0001] The present invention relates to the field of aluminum surface treatment equipment, and specifically relates to a water pattern mark treatment system and its operation method. Background Art

[0002] Water pattern marks are quality defects or flaws on the surface of aluminum materials after surface treatment, which affect the appearance of products. There are many factors causing water pattern marks. Some are related to the material and material processing technology; some are related to incomplete degreasing, polishing or water washing before anodic oxidation or coloring; some are related to the rapid drying of the water solution before anodic oxidation or coloring and the deposition of water marks. For the treatment of water pattern marks generated during these production processes, certain effects have been achieved through facility or process improvement or subsequent remedies. For example, the utility model patent with the authorization announcement number CN217869139U discloses a water pattern mark treatment system, which "cools the aluminum parts products that have completed wax removal / degreasing through a spraying device, and at the same time, the spraying device can also clean the water on the surface of the aluminum parts products, and water pattern marks will not be formed during the cooling process of the aluminum parts products...". However, after anodic oxidation or coloring of aluminum materials, boiling water or steam is generally required for sealing. Due to the influence of the remaining temperature and residual water solution on the aluminum materials, water pattern marks are likely to be formed on their surfaces. If not treated in time, it will also affect the appearance of the products. Currently, most of the treatment methods for water pattern marks generated at this stage still use cold water cooling, draining, manual wiping or natural air drying. However, before draining or natural air drying, for some water solution accumulated on the upper surface or inner surface, the remaining temperature on the aluminum materials has quickly evaporated the water and left water pattern marks; in addition, manual wiping has a high labor intensity, low efficiency and is easy to miss, and there is also a risk of missing wiping and forming water pattern marks. Especially for some complex aluminum materials formed by extrusion or stretching into a special-shaped or multi-layer cross-section structure, it is easier to hide water solution inside the sandwich layer or curved surface. Even through draining, manual wiping or natural air drying, the hidden water solution cannot be cleaned, and water pattern marks will still be formed after subsequent seepage; moreover, this stage is at the end of production, and the generated water pattern marks are inconvenient to be remedied by other measures and will directly affect the appearance of the products. In view of this, it is necessary to improve product quality and operation efficiency through a more effective water pattern mark treatment system, and this case thus arises. Summary of the Invention

[0003] To overcome the deficiencies in the prior art, the present invention discloses a water pattern mark processing system and its operation method. The water pattern mark processing system includes a cooling unit, a blowing unit, a vibration exciting unit, a suction unit, and a swinging and transferring unit. The cooling unit is provided with a water tank capable of containing circulating chilled water. The blowing unit is densely provided with a number of blowing nozzles around the inner circumference of the air box. The vibration exciting unit is provided with a vibrating screen, and the suction unit is provided with a suction member. The cooling unit of the present invention can cool the aluminum material after being sealed with boiling water or steam. The blowing unit can blow off the water liquid on the surface of the aluminum material. The vibration exciting unit can perform high-frequency vibration on the aluminum material to make the hidden water liquid overflow. The suction unit can extract and remove the water liquid on the surface of the aluminum material. The swinging and transferring unit can swing and transfer the aluminum material. The operation method of the present invention is to first cool the aluminum material after being sealed with boiling water or steam, then swing it to drain water, strongly blow the surface water liquid, perform high-frequency vibration to make the hidden water liquid overflow, and then use negative pressure suction to quickly and fully remove the remaining water liquid, thereby avoiding the generation of water pattern marks. By sequentially arranging the cooling unit, the blowing unit, the vibration exciting unit, the suction unit, and the swinging and transferring unit above them, the water liquid on the surface and inside of the sealed aluminum material can be fully overflowed and suctioned and removed by forced means without subsequent manual treatment, thereby avoiding the remaining water pattern marks on the sealed aluminum material and improving the product quality and operation efficiency.

[0004] To achieve the above object, the technical solution adopted by the present invention is as follows:

The suction and sweeping head is provided with a flat nozzle-shaped suction and sweeping port and a holding handle. The negative pressure box and the suction and sweeping head are both connected to the suction fan through flexible air pipes, and the suction and sweeping head can be handheld and moved.

[0010] The described swinging unit is provided with a plurality of electric hoists below two parallel tracks. Every two electric hoists form a group, and the two electric hoists of each group are symmetrically arranged on the two tracks. The two electric hoists of each group can be lifted and lowered synchronously and moved slowly left or right synchronously, or can be moved quickly left and right synchronously to swing the suspended aluminum material left and right, or the two electric hoists of each group can lift and lower one by one to swing the suspended aluminum material up and down.

[0013] For the water pattern mark treatment system, its operation method includes the following steps:

[0014] Step a: Transfer the sealed aluminum material to the water pool of the cooling unit through the swinging unit;

[0015] Step b: Send the externally circulating chilled water into the water pool through the water inlet to cool the aluminum material sealed by boiling water or steam;

For the aluminum material after being sealed by boiling water or steam, the forced swing promotes the rapid dripping of the water and liquid accumulated on the upper surface and inside that are not easy to flow, and the water and liquid on the aluminum material are strongly blown and sprayed by the blower to reduce the accumulation of water and liquid, which can avoid the formation of water pattern marks due to the easy accumulation of water and liquid or slow water flow and the rapid evaporation of water by the remaining temperature of the aluminum material in the static draining or natural air drying method; Second, a vibration excitation unit and a suction unit are provided. The vibration excitation unit can vibrate the aluminum material at high frequency to make the hidden water and liquid of the aluminum material overflow, and the water and liquid are extracted and removed through the suction unit, which can forcibly remove the water and liquid hidden in the sandwich layer or curved surface inside of some complex aluminum materials with a special-shaped or multi-layer structure cross-section formed by extrusion or stretching, avoiding the subsequent seepage to form water pattern marks; Third, this operation method first cools, then swings and blows and sprays, so that a large amount of water and liquid are forcibly separated and dripped, and then the internal hidden small amount of water and liquid is removed by vibration excitation and suction. The efficiency is high and the water and liquid are treated more thoroughly, avoiding the quality impact on subsequent products caused by the water pattern marks generated by the seepage of the internal hidden water and liquid. By sequentially arranging a cooling unit, a blowing unit, a vibration excitation unit, a suction unit and a transfer and swing unit placed above them, the water and liquid on the surface and inside of the sealed aluminum material can fully overflow and be sucked and removed by forced means without subsequent manual treatment, thereby avoiding the residual water pattern marks on the sealed aluminum material and improving the product quality and operation efficiency. The present invention has reasonable design, simple structure, low cost and is convenient for popularization. Description of the Drawings
