Description

Technical Field

[0001] The utility model belongs to the technical field of steel plate spraying, and specifically relates to a device for spraying wax particles on the surface of galvanized steel plates. Background Technique

[0002] A galvanized steel plate is a steel plate with a layer of zinc plated on its surface. Zinc plating is a commonly used method for metal anti-corrosion. By covering a layer of zinc on the metal surface, it can prevent the metal from coming into contact with air or moisture.

[0003] Although the galvanized steel plate itself has a layer of zinc to prevent corrosion, in some special environments, such as corrosive liquids like strong acids and strong alkalis, the simple zinc plating layer is difficult to meet the protection requirements. By spraying wax particles on the surface of the galvanized steel plate, an additional protective film can be formed on the zinc plating layer, strengthening the anti-corrosion performance of the galvanized steel plate.

[0004] During the spraying process of the galvanized steel plate, when the nozzle is used for a long time, residues will be generated when the spraying material passes through the nozzle position, which easily causes the nozzle aperture to become smaller, making it impossible for the spraying material to pass through smoothly when it is ejected through the nozzle, resulting in the coating being unable to be evenly sprayed on the surface of the galvanized steel plate and causing the spraying quality to decline.

Specific embodiments

[0024] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Such as Figures 1 to 5As shown in the figure, a wax particle spraying device for the surface of galvanized steel sheets according to an embodiment of the present utility model includes a workbench 1; a plurality of electric push rods 10 are fixedly connected to the top of the workbench 1; first fixing frames 11 are fixedly connected to the ends of two opposite electric push rods 10; a second fixing frame 12 is slidably connected to the middle of the two first fixing frames 11; two spraying nozzles 13 are fixedly connected to the middle of the second fixing frame 12; a fixing plate 14 is fixedly connected to the middle of the second fixing frame 12; the fixing plate 14 is fixedly connected between the two spraying nozzles 13; a spring 16 is fixedly connected to the bottom of the fixing plate 14; a spring 16 is fixedly connected to the bottom of the fixing plate 14; the spring 16 is fixedly connected at the position corresponding to the first telescopic rod 15; a fixing ball 17 is fixedly connected to the end of the first telescopic rod 15; the end of the spring 16 is fixedly connected to the middle of the fixing ball 17; two fixing rods 18 are fixedly connected to the middle of the fixing ball 17; the two fixing rods 18 are arranged oppositely; the end of the fixing rod 18 is circular; a plurality of steel needles 19 are fixedly connected to the middle of the fixing rod 18; the plurality of steel needles 19 are fixedly connected at the position corresponding to the spraying nozzle 13; two support plates 20 are fixedly connected to the side walls of the two first fixing frames 11; the two support plates 20 are arranged oppositely; a guide plate 111 is fixedly connected to the side wall of the support plate 20; the guide plate 111 is inclined; during operation, the galvanized steel sheet is placed in the middle of the workbench 1, the plurality of electric push rods 10 are controlled to extend and retract, the spraying nozzle 13 is adjusted to a specified height from the galvanized steel sheet, the second fixing frame 12 is controlled to reciprocate in the middle of the two first fixing frames 11, the spraying nozzle 13 is energized and then opened to spray towards the position of the galvanized steel sheet. When the second fixing frame 12 moves to one side of the first fixing frame 11, the fixing ball 17 first contacts the guide plate 111. When the second fixing frame 12 continues to move, due to the inclination of the guide plate 111, the fixing ball 17 is squeezed, causing the first telescopic rod 15 and the spring 16 to contract. When the fixing ball 17 contracts through the first telescopic rod 15 and the spring 16, the fixing rod 18 moves upward at the same time, causing the plurality of steel needles 19 to enter the middle of the spraying nozzle 13. When the second fixing frame 12 moves away from the guide plate 111, the plurality of steel needles 19 are reset by the elasticity of the spring 16 and remain at the bottom position of the spraying nozzle 13. Through the plurality of steel needles 19, it can effectively reduce the accumulation of impurities and small particles in the coating in the middle of the spraying nozzle 13 during long-term operation, resulting in blockage. By inserting the plurality of steel needles 19 into the middle of the spraying nozzle 13, the blocked substances can be effectively cleaned, which can effectively reduce the non-uniformity of the coating spraying caused by the blocked spraying nozzle 13, effectively increase the uniformity during the spraying of the galvanized steel sheet, and enable the coating to be sprayed evenly, thereby improving the quality and effect of spraying.

[0026] As Figure 1 and Figure 5As shown, a groove 2 is provided at the end of the workbench 1; a slide rail 21 is fixedly connected to the side wall of the groove 2; two motors 22 are slidably connected to the middle of the slide rail 21; the output end of the motor 22 passes through the top of the workbench 1; two through grooves 23 are provided in the middle of the slide rail 21; the output end of the motor 22 is arranged in the middle of the through groove 23; a roller 25 is fixedly connected to the output end of the motor 22; two support rods 26 are fixedly connected to the top of the workbench 1; an elastic plate 27 is fixedly connected to the middle of the support rod 26; the two elastic plates 27 are arranged oppositely; when working, the two motors 22 are slid in the middle of the slide rail 21, so that the two sides of the galvanized steel plate are in contact with the roller 25, the motors 22 are powered on and turned on, so that the output ends of the two motors 22 rotate, and the roller 25 is driven to rotate by the motor 22, one end of the galvanized steel plate is placed between the two rollers 25, and the two rollers are driven to rotate. When the rollers 25 rotate, the galvanized steel plate moves, and the galvanized steel plate is positioned by the two rollers 25. When one end of the galvanized steel plate moves to one side of the two elastic plates 27, the motor 22 is controlled to stop rotating, and the galvanized steel plate is sprayed through the spray nozzle 13. When the spraying is completed, another galvanized steel plate is placed. When the other galvanized steel plate is pushed, the galvanized steel plate that has been sprayed is pushed at the same time. The two elastic plates 27 under pressure generate elasticity to move the galvanized steel plate that has been sprayed out. The two rollers 25 can effectively limit the positions of the two sides of the galvanized steel plate, reduce the shaking or shaking of the galvanized steel plate caused by external force during the spraying process, and can make the paint evenly sprayed on the surface of the galvanized steel plate, effectively reducing the waste of paint caused by uneven spraying of the galvanized steel plate, and can adapt to galvanized steel plates of different sizes, effectively improving the versatility and adaptability of the equipment.

[0027] like Figure 1 , Figure 5 , Figure 6As shown, two second telescopic rods 3 are fixedly connected to the top of the workbench 1; the two second telescopic rods 3 are fixedly connected to the end far from the groove 2; the ends of the two second telescopic rods 3 are fixedly connected with an exhaust pipe 31; a plurality of exhaust holes 32 are formed in the middle of the exhaust pipe 31; a hot air blower 33 is fixedly connected to the side wall of the workbench 1; a telescopic hose 34 is fixedly connected to the top of the hot air blower 33; the end of the telescopic hose 34 is fixedly connected to the middle of the exhaust pipe 31; during operation, after the galvanized steel plate is sprayed, it passes through the bottom of the exhaust pipe 31. After the hot air blower 33 is powered on and started, the hot air flow generated inside the hot air blower 33 enters the middle of the telescopic hose 34. The second telescopic rod 3 is telescoped to adjust the exhaust pipe 31 to a suitable position relative to the galvanized steel plate. The air flow is discharged into the exhaust pipe 31 through the end of the telescopic hose 34, and the hot air flow blows to the surface of the galvanized steel plate after spraying through the plurality of exhaust holes 32. The hot air flow contacts the surface of the sprayed galvanized steel plate through the plurality of exhaust holes 32, which can increase the firmness and durability of the spray coating on the surface of the galvanized steel plate, reduce the residual moisture on the galvanized steel plate after spraying, and can be dried in time to reduce the problems of coating peeling or bubbling. The moisture and volatile substances of the coating can be effectively volatilized, and the quality decline caused by the uneven coating of the galvanized steel plate can be reduced.

[0028] As Figure 1 and Figure 4 shown, a connecting rod 4 is fixedly connected to the middle of two of the electric push rods 10; the connecting rod 4 is fixedly connected to the side close to the roller 25; a threaded brush 41 is fixedly connected to the middle of the connecting rod 4; during operation, when the galvanized steel plate is moved by the two rollers 25, the sprayed surface of the galvanized steel plate comes into contact with the threaded brush 41. When the galvanized steel plate continues to move, the dust and impurities on the surface of the galvanized steel plate are cleaned by the threaded brush 41. The dust and impurities on the surface can be removed by the threaded brush 41, which can penetrate into the tiny gaps and depressions on the surface of the galvanized steel plate, effectively reducing the dust and impurities that are difficult to reach. The dust and impurities on the surface of the galvanized steel plate can be reduced, so that the paint can be evenly and firmly attached to the surface of the steel plate, reducing the problems of bubbles and peeling of the coating caused by the existence of impurities, and effectively improving the quality of the spraying of the galvanized steel plate.

[0029] As Figure 1 and Figure 4As shown, a collection box 5 is slidably connected to the middle of the connecting rod 4; a scraping plate 51 is fixedly connected to the middle of the collection box 5; the end of the scraping plate 51 is attached to the surface of the connecting rod 4. During operation, after the threaded brush 41 finishes cleaning the surface of the galvanized steel plate, dust and impurities accumulate on the surface of the threaded brush 41. Slide the collection box 5 in the middle of the connecting rod 4 to cause elastic bending of the threaded brush 41. The scraping plate 51 in the middle of the collection box 5 scrapes off the dust and impurities on the surface of the threaded brush 41. The dust and impurities peeled off from the middle of the threaded brush 41 fall to the bottom of the collection box 5 for collection, and then subsequent processing is carried out. The scraping plate 51 can effectively scrape off the dust and impurities adsorbed on the surface of the threaded brush 41, reduce the accumulation of these residues on the surface of the threaded brush 41, effectively reduce the accumulation of dust and impurities on the surface of the threaded brush 41, reduce the secondary pollution caused when cleaning the next galvanized steel plate, and can reduce the contact between the dust and impurities on the surface of the threaded brush 41 and the surface of the galvanized steel plate again during the cleaning process, thus avoiding problems such as scratches or damage.

[0030] As Figure 1 and Figure 5 shown, a wind collecting hood 6 is fixedly connected to the middle of the exhaust pipe 31; the wind collecting hood 6 is fixedly connected at the positions of a plurality of exhaust holes 32. During operation, when the hot air flow is discharged from the plurality of exhaust holes 32 to the surface of the galvanized steel plate, the wind collecting hood 6 guides the direction of the air flow, so that the air flow evenly blows onto the surface of the galvanized steel plate. The wind collecting hood 6 can make the hot air flow discharged from the middle of the plurality of exhaust holes 32 blow more concentratedly and stably onto the surface of the galvanized steel plate, can quickly and evenly heat the surface of the galvanized steel plate after spraying, effectively promote better adhesion of the coating to the surface of the galvanized steel plate, effectively increase the drying speed of the coating, and thus effectively improve the efficiency of the spraying work of the galvanized steel plate.

[0031] During operation, place the galvanized steel plate in the middle of the workbench 1, control the telescopic movement of multiple electric push rods 10, adjust the spraying nozzle 13 to the specified height relative to the galvanized steel plate, control the reciprocating movement of the second fixing bracket 12 in the middle of the two first fixing brackets 11, energize the spraying nozzle 13 and turn it on to spray towards the position of the galvanized steel plate. When the second fixing bracket 12 moves to one side of the first fixing bracket 11, the fixing ball 17 first comes into contact with the guide plate 111. When the second fixing bracket 12 continues to move, due to the inclination of the guide plate 111, the fixing ball 17 is squeezed, causing the first telescopic rod 15 and the spring 16 to contract. When the fixing ball 17 contracts through the first telescopic rod 15 and the spring 16, the fixing rod 18 moves upward simultaneously, enabling multiple steel needles 19 to enter the middle of the spraying nozzle 13. When the second fixing bracket 12 moves away from the guide plate 111, the multiple steel needles 19 are reset by the elasticity of the spring 16 and remain at the bottom position of the spraying nozzle 13. Slide the two motors 22 in the middle of the slide rail 21 so that both sides of the galvanized steel plate come into contact with the rollers 25. Energize the motors 22 and turn them on, causing the output ends of the two motors 22 to rotate, driving the rollers 25 to rotate through the motors 22. Place one end of the galvanized steel plate between the two rollers 25, and the galvanized steel plate moves as the two rollers 25 rotate. Position the galvanized steel plate through the two rollers 25. When one end of the galvanized steel plate moves to one side of the two elastic plates 27, control the motors 22 to stop rotating, and spray the galvanized steel plate through the spraying nozzle 13. After spraying, place another galvanized steel plate. When the other galvanized steel plate is pushed, it simultaneously pushes the sprayed galvanized steel plate. The two elastic plates 27 under pressure produce elasticity to move the sprayed galvanized steel plate out. When the galvanized steel plate is sprayed, it passes under the bottom of the exhaust pipe 31. Energize the hot air blower 33 and turn it on, causing the hot air flow generated inside the hot air blower 33 to enter the middle of the telescopic hose 34. Extend and retract the second telescopic rod 3 to adjust the exhaust pipe 31 to a suitable position relative to the galvanized steel plate. Discharge the air flow from the end of the telescopic hose 34 into the interior of the exhaust pipe 31. The hot air flow blows towards the surface of the galvanized steel plate after spraying through multiple exhaust holes 32. During the process of moving the galvanized steel plate through the two rollers 25, the sprayed surface of the galvanized steel plate comes into contact with the thread brush 41. When the galvanized steel plate continues to move, the thread brush 41 cleans the dust and impurities on the surface of the galvanized steel plate. When the thread brush 41 finishes cleaning the surface of the galvanized steel plate, the dust and impurities accumulate on the surface of the thread brush 41. Slide the collection box 5 on the connecting rod 4, causing the thread brush 41 to elastically bend. Scrape the dust and impurities on the surface of the thread brush 41 with the scraper 51 in the middle of the collection box 5. The dust and impurities peeled off from the middle of the thread brush 41 fall to the bottom position of the collection box 5 for collection, and then subsequent processing can be carried out. After the hot air flow is discharged from the multiple exhaust holes 32 towards the surface of the galvanized steel plate, the air flow direction is guided by the air collecting hood 6 to evenly blow the air flow towards the surface of the galvanized steel plate.
