Description

Technical Field

[0001] This utility model relates to the field of metal sheet surface treatment technology, and more specifically, it relates to a pretreatment device for metal sheet surface treatment. Background Technology

[0002] During the processing of metal sheets, impurities such as oil, dust, and debris may remain. In the etching process of metal sheets, these impurities affect the contact between the etching solution and the metal surface, resulting in uneven etching or unclear patterns. Therefore, before the etching process of metal sheets, the surface debris, dust, oil, and other impurities are cleaned to avoid affecting the subsequent processing results.

[0003] Utility model patent application number 202020997565.2 discloses a surface pretreatment device for metal etching. Depending on the thickness of the metal plate to be cleaned, the device involves unscrewing the bolts on the first mounting bracket. After the bolts separate from the adjustment groove on the connecting bracket, the first mounting bracket slides up and down. The first mounting bracket moves on the connecting bracket via a sliding groove and a limiting protrusion. Once the cleaning brush below the first mounting bracket is adjusted to the desired height, the bolts on the first mounting bracket are tightened again. The bolts then press against the adjustment groove on the connecting bracket, adjusting the height of the cleaning brush below the first mounting bracket. The same steps are then followed to adjust the height of the dust removal cloth below the second mounting bracket. A motor drives the transmission roller to drive the conveyor belt, allowing the metal plates placed in the corresponding placement slots to pass sequentially through the cleaning brush and dust removal cloth for cleaning. The limiting strip limits the metal plates to prevent them from shifting. This device can clean the surfaces of metal plates of different thicknesses and prevents misalignment of the plates on the conveyor belt during cleaning, thus facilitating the cleaning of the metal plate surface.

[0004] While existing technologies can remove debris and dust from the surface of metal sheets through the physical friction and wiping action of cleaning brushes and dust cloths, they cannot effectively remove oil stains from the surface of metal sheets, resulting in unsatisfactory cleaning effects. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a pretreatment device for surface treatment of metal sheets.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A pretreatment device for surface treatment of metal sheets includes a cleaning tank and a washing liquid tank that are interconnected. The washing liquid tank contains a cleaning agent for cleaning oil stains on the metal sheet. The cleaning tank is connected to a fixed platform. Positioning components for fixing the metal sheet are connected to both the fixed platform and the side wall of the cleaning tank. A first nozzle and a second nozzle corresponding to the metal sheet being cleaned are connected inside the cleaning tank. A first water supply pipe connected to the first nozzle and a second water supply pipe connected to the second nozzle are connected to the cleaning tank. The first water supply pipe is connected to the washing liquid tank, and the second water supply pipe is connected to a faucet. A diaphragm pump for delivering the cleaning agent in the washing liquid tank to the first nozzle is connected to the first water supply pipe, and a water pump for delivering water to the second nozzle is connected to the second water supply pipe.

[0017] Reference Figures 1 to 3 The embodiments of this utility model will be further described below.

[0018] A pretreatment device for surface treatment of metal sheets includes a cleaning tank 2 and a washing liquid tank 3 connected to each other. The washing liquid tank 3 contains a cleaning agent for cleaning oil stains on the metal sheet 1. The cleaning tank 2 is fixedly connected to a fixing platform 4. Positioning components 100 for fixing the metal sheet 1 are connected to the fixing platform 4 and the side wall of the cleaning tank 2. The cleaning tank 2 is connected to a first nozzle 5 and a second nozzle 6 corresponding to the cleaning of the metal sheet 1. The first nozzle 5 and the second nozzle 6 with appropriate spray range are selected according to the area of ​​the metal sheet. The cleaning tank 2 is connected to a first water supply pipe 7 connected to the first nozzle 5 and a second water supply pipe 8 connected to the second nozzle 6. The first water supply pipe 7 is connected to the washing liquid tank 3, and the second water supply pipe 8 is connected to a faucet and placed in the cleaning agent. The first water supply pipe 7 is connected to a diaphragm pump 9 for delivering the cleaning agent in the washing liquid tank 3 to the first nozzle 5, and the second water supply pipe 8 is connected to a water pump 10 for delivering water to the second nozzle 6. The diaphragm pump 9 and the water pump 10 are both fixed to the outer wall of the cleaning tank 2.

[0019] Working principle: The metal sheet 1 is placed on the fixed platform 4. The fixed platform 4 and the positioning parts 100 on the side wall of the cleaning box 2 securely fix the metal sheet 1 in the cleaning box 2. The first nozzle 5 is connected to the washing solution tank 3 through the first water supply pipe 7. The diaphragm pump 9 works to deliver the cleaning agent in the washing solution tank 3 to the first nozzle 5. The cleaning agent is sprayed out by the first nozzle 5 to clean the oil, debris, and dust on the surface of the metal sheet 1. After the first nozzle 5 cleans, the second nozzle 6 is connected to the faucet through the second water supply pipe 8. The water pump 10 works to deliver clean water from the faucet to the second nozzle 6. The cleaning agent is sprayed out by the second nozzle 6 to further rinse the surface of the metal sheet 1 and improve its cleaning effect. The cleaning effect on the metal sheet 1 is achieved by rinsing away the residual cleaning agent on the surface of the metal sheet 1, thus preventing the cleaning agent residue from reducing the cleaning effect. The water pump 10 is set to avoid the problem that insufficient water supply pressure from the faucet will prevent clean water from being delivered to the second nozzle 6. The fixed platform 4 raises the metal sheet 1, preventing the bottom of the metal sheet 1 from contacting the used cleaning agent in the cleaning box 2 or the wastewater that has rinsed the metal sheet 1, which would affect the cleaning effect. Ultimately, it can clean the debris, dust and oil stains on the surface of the metal sheet, avoiding the problem that physical friction and wiping will not be able to effectively remove the oil stains on the surface of the metal sheet, thus improving the cleaning effect.

[0020] The cleaning tank 2 is connected to a water pipe 11 and a guide pipe 12. The water pipe 11 is connected to the washing liquid tank 3. Both the water pipe 11 and the guide pipe 12 are equipped with valves 13. The guide pipe 12 is connected to the factory's drainage system. The cleaning tank 2 is equipped with a filter screen 14 for filtering impurities in the cleaning agent. The filter screen 14 corresponds to the water pipe 11. A magnetic ring 15 is connected to the filter screen 14. The inner wall of the cleaning tank 2 is made of metal material that is magnetically connected to the magnetic ring 15.

[0021] After the first nozzle 5 sprays cleaning agent to clean the metal sheet 1, the cleaning agent falls into the cleaning tank 2. Open the valve 13 on the water pipe 11 and close the valve 13 on the guide pipe 12 to facilitate the cleaning agent in the cleaning tank 2 to flow into the washing liquid tank 3 through the water pipe 11 for recycling. When the cleaning agent in the cleaning tank 2 flows into the washing liquid tank 3 through the water pipe 11, the filter screen 14 filters the impurities in the cleaning agent, so that the cleaning agent entering the washing liquid tank 3 can be recycled, reducing the waste of cleaning agent and lowering production costs. The filter screen 14 is detachably connected to the inner wall of the cleaning tank 2 through the magnetic ring 15, making it easy to remove the filter screen 14 for cleaning and avoiding affecting the subsequent filtration effect.

[0022] When rinsing the metal sheet 1 with clean water, open valve 13 on the guide pipe 12 and close valve 13 on the water pipe 11. This allows the wastewater after cleaning to be discharged through the guide pipe 12 into the factory's drainage system for centralized treatment, which meets environmental protection requirements, reduces environmental pollution, and prevents the wastewater from rinsing the metal sheet 1 from accumulating in the cleaning box 2.

[0023] The positioning component 100 includes two positioning plates 16 placed on both sides of the metal plate 1 and two elastic blocks 17 respectively connected to the two positioning plates 16. The elastic blocks 17 abut against the metal plate 1. When the metal plate 1 is fixed by the fixing component, the metal plate 1 is placed between the two positioning plates 16. At this time, the metal plate 1 squeezes the elastic blocks 17 on the positioning plates 16 to compress and deform them. Since the compressed elastic blocks 17 are elastic, the compressed elastic blocks 17 will apply a reverse elastic force to the metal plate 1, thereby abutting tightly against the metal plate 1 and fixing the metal plate 1, thus realizing the fixing of the metal plate 1 by the fixing component.

[0024] The cleaning solution tank 3 includes an inlet 18 for easy pouring of cleaning agent into the cleaning solution tank 3. When the cleaning agent in the cleaning solution tank 3 has a significantly reduced cleaning effect due to repeated use and needs to be replaced, the valve 13 on the guide pipe 12 is opened and the valve 13 on the water pipe 11 is closed, so that the cleaning agent falling into the cleaning tank 2 can be directly discharged into the factory's drainage system for centralized treatment through the guide pipe 12, and new cleaning agent is added through the inlet 18 to ensure the cleaning effect.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
