Technical Field
[0001] This utility model relates to the field of galvanized steel sheet processing, specifically to an alloy coating coating spraying equipment. Background Technology
[0002] Galvanized steel sheet is a welded steel sheet with a hot-dip galvanized or electro-galvanized layer on its surface. It is widely used in construction, home appliances, automobiles and ships, container manufacturing, electromechanical industry and other fields. The main function of galvanized steel sheet is to prevent the steel sheet surface from being corroded, thereby extending its service life.
[0003] The processing flow of galvanized steel sheet typically includes the following steps: surface treatment, galvanizing, drying, processing, and coating / coating spraying. Among these, coating / coating spraying is one of the important steps in the processing of galvanized steel sheet, as it can improve the corrosion resistance, wear resistance, or aesthetics of the steel sheet.
[0004] In existing methods, galvanized steel sheets are typically coated with a spray nozzle using a spray gun. However, during production and observation, it has been found that galvanized steel sheets are sometimes misaligned during transportation. This makes it difficult for the spray gun to evenly coat the surface of the galvanized steel sheet, thereby reducing the coating quality of the equipment.
[0005] Therefore, an alloy coating coating spraying equipment is proposed to address the above problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0025] Specific implementation examples are given below.
[0026] Please see Figures 1 to 5As shown in the embodiment of this utility model, an alloy coating spraying device includes a support base 1; a connecting plate 12 is fixedly connected to the top of the support base 1; a motor 13 is fixedly connected to the top of the connecting plate 12; a first gear 14 is fixedly connected to the output end of the motor 13; the first gear 14 and the connecting plate 12 are rotatably connected; a second gear 15 is symmetrically rotatably connected to the inner sidewall of the connecting plate 12; the second gear 15 and the first gear 14 are meshed; a fixed seat 152 is fixedly connected to the bottom of the second gear 15; the fixed seat 152... A roller 16 is rotatably connected to the bottom of the support base 1; the fixed base 152 and the second gear 15 are eccentrically arranged; a spraying assembly 17 is installed on the inner side wall of the connecting plate 12; a fixing groove 18 is opened in the middle of the support base 1; multiple conveying rollers 182 are rotatably connected to the middle of the fixing groove 18; a heating assembly 19 is fixedly connected to the middle of the connecting plate 12; during operation, after the galvanized steel plate is sent to the top of the support base 1, the motor 13 is started. After the motor 13 starts, the first gear 14 will rotate. When the first gear 14 rotates, it will mesh with a pair of second gears 15, causing the first gear 14 to rotate. When the second gear 15 rotates, because the fixed base 152 and the second gear 15 are eccentrically arranged, the rotation of the second gear 15 will drive the fixed base 152 and the roller 16 to move together, causing a change in the distance between the pair of rollers 16. At this time, the rollers 16 will move closer to the galvanized steel sheet until they come into contact with it. At this point, the motor 13 can be stopped and the equipment started. After the equipment starts, the conveyor roller 182 will rotate and transport the galvanized steel sheet. When the galvanized steel sheet moves, it will be squeezed by the rollers 16, which will keep the galvanized steel sheet in a centered position. When the coating unit 17 reaches the galvanized steel sheet, it will spray the coating onto the surface of the galvanized steel sheet. The coated galvanized steel sheet will then move to the heating unit 19 and be heated and dried by the heating unit 19. The roller 16 will rotate under the meshing action of the first gear 14 and the second gear 15 of the fixed seat 152 and squeeze the galvanized steel sheet. This will achieve the positioning and fixation of the galvanized steel sheet during the coating process, reduce the offset and shaking that occurs when the galvanized steel sheet moves, improve the accuracy of the coating on the surface of the galvanized steel sheet by the coating unit 17, and enhance the uniformity of the coating on the surface of the galvanized steel sheet.
[0027] Please see Figures 2 to 4As shown, the fixed base 152 is connected to a first air inlet pipe 2 in the middle; the fixed base 152 and the roller 16 are connected; the roller 16 has multiple first circular holes 22 in the middle; a ball 23 is slidably fitted in the middle of the first circular hole 22; a connecting rod 24 is fixedly connected to the middle of the ball 23; a pressure plate 26 is fixedly connected to the end of the connecting rod 24; multiple springs 25 are fixedly connected to the middle of the pressure plate 26; the springs 25 and the roller 16 are also fixedly connected; when the equipment is started, the operator can connect an air pump to the first air inlet pipe 2 so that the air pump can input air into the fixed base 152 and the roller 16 through the first air inlet pipe 2. After the airflow enters the roller 16, it will be ejected through the first circular holes 22 and reach the surface of the galvanized steel plate. The airflow will clean the surface of the galvanized steel plate and reduce the dust on the surface of the galvanized steel plate. When the galvanized steel plate comes into contact with the roller 16, it will also interact with the pressure plate 26. When the pressure plate 26 is subjected to pressure, it moves closer to the roller 16 and compresses the spring 25. As the pressure plate 26 moves, it also moves the connecting rod 24 and the ball 23 together. When the ball 23 moves, it disengages from the first circular hole 22, at which point the first circular hole 22 is in the open state. The first circular hole 22 that is not in contact with the galvanized steel plate is sealed by the ball 23. Because the total air volume inside the roller 16 remains unchanged, the air volume at the first circular hole 22 that is in contact with the galvanized steel plate will be greater, increasing the airflow reaching the surface of the galvanized steel plate. The ball 23 will disengage from the first circular hole 22 along with the connecting rod 24 and the pressure plate 26 under the pressure of the galvanized steel plate, so that the first circular hole 22 that is in contact with the galvanized steel plate is in the open state, increasing the airflow at the first circular hole 22, enhancing the cleaning effect of the airflow on the galvanized steel plate, reducing dust and other impurities adhering to the surface of the galvanized steel plate, and increasing the contact area between the coating and the galvanized steel plate.
[0028] Please see Figure 4 As shown, multiple diversion plates 3 are fixedly connected to the middle of the pressure plate 26; the diversion plate 3 has a wave-shaped structure; multiple second circular holes 32 are opened in the middle of the diversion plate 3; after the airflow is ejected from the first circular hole 22, it will reach the diversion plate 3 and flow along the surface of the diversion plate 3. Because the diversion plate 3 has a wave-shaped structure, the diversion plate 3 will reduce the flow velocity of the airflow, thereby increasing the contact time between the airflow and the galvanized steel plate. At the same time, the airflow will flow out from the second circular hole 32 and the edge of the diversion plate 3, increasing the flow range of the airflow and further increasing the airflow reaching the surface of the galvanized steel plate.
[0029] Please see Figure 4 As shown, a plurality of bristles 4 are fixedly attached to the middle of the sphere 23; the bristles 4 are arranged in an array; when the sphere 23 moves, it will drive the bristles 4 to move together. When the bristles 4 move, they will come into contact with the inner wall of the first circular hole 22 and clean the inner wall of the first circular hole 22, reducing the paint and other impurities remaining on the inner wall of the first circular hole 22 and improving the cleanliness of the inner wall of the first circular hole 22.
[0030] Please see Figure 1 and Figure 5 As shown, the heating assembly 19 includes an electric actuator 5; the output end of the electric actuator 5 is fixedly connected to a top plate 52; a heating wire 54 is fixedly connected to the bottom of the top plate 52; a second air inlet pipe 53 is connected to the middle of the top plate 52; after the equipment is started, the electric actuator 5 will also start and move the top plate 52 closer to the galvanized steel plate, and the heating wire 54 will generate heat after being energized. After the operator connects the second air inlet pipe 53 to an external air pump, the air pump will deliver air into the second air inlet pipe 53. When the airflow passes through the heating wire 54, the heating wire 54 will heat the airflow. Subsequently, the hot airflow will reach the surface of the galvanized steel plate and dry the surface of the galvanized steel plate, thus accelerating the drying speed of the coating on the surface of the galvanized steel plate.
[0031] Please see Figure 5 As shown, an elastic cloth 6 is fixedly connected to the bottom of the top plate 52; a pressure ring 62 is fixedly connected to the bottom of the elastic cloth 6; when the airflow is ejected from the heating wire 54, it will reach the interior of the elastic cloth 6, and the hot airflow will flow inside the elastic cloth 6 and diffuse towards the galvanized steel plate, so that the hot airflow can flow more concentratedly to the surface of the galvanized steel plate, thereby enhancing the drying effect of the equipment on the galvanized steel plate.
[0032] Please see Figure 1 As shown, a collection box 7 is fixedly connected to the bottom of the support base 1; the collection box 7 is located at the bottom of the fixed groove 18; when the spraying assembly 17 sprays the galvanized steel plate, splashed paint will flow out from the fixed groove 18, and this paint will reach the inside of the collection box 7 and be collected by the collection box 7, so as to realize the recycling and utilization of the paint by the equipment.
[0033] Working principle: After the galvanized steel sheet is fed to the top of the support base 1, the motor 13 is started. The motor 13 causes the first gear 14 to rotate. When the first gear 14 rotates, it meshes with a pair of second gears 15, causing the second gears 15 to rotate as well. Because the fixed base 152 and the second gears 15 are eccentrically positioned, the rotation of the second gears 15 drives the fixed base 152 and rollers 16 to move together, changing the distance between the rollers 16. At this time, the rollers 16 move closer to the galvanized steel sheet until they contact it. At this point, the motor 13 can be stopped and the equipment started. After the equipment starts, the conveyor rollers 182 rotate and transport the galvanized steel sheet. As the galvanized steel sheet moves, it is subjected to the squeezing action of the rollers 16, causing... The galvanized steel sheet is kept centered during movement. When the galvanized steel sheet moves to the spraying component 17, the spraying component 17 sprays paint onto the surface of the galvanized steel sheet. Finally, the sprayed galvanized steel sheet continues to move to the heating component 19 and is heated and dried by the heating component 19. When the equipment is started, the operator can connect an external air pump to the first air inlet pipe 2 so that the air pump can input air into the fixed seat 152 and the roller 16 through the first air inlet pipe 2. After the airflow enters the roller 16, it will be ejected through the first round hole 22 and reach the surface of the galvanized steel sheet. The airflow will clean the surface of the galvanized steel sheet and reduce the dust on the surface of the galvanized steel sheet. When the galvanized steel sheet comes into contact with the roller 16, it will also come into contact with the pressure plate 26. After the pressure plate 26 is subjected to pressure, it will push against the roller. Roller 16 moves closer to spring 25 and compresses it. As pressure plate 26 moves, it also moves connecting rod 24 and ball 23 together. Ball 23 disengages from the first hole 22, leaving it open. The first hole 22, which is not in contact with the galvanized steel plate, is sealed by ball 23. Because the total airflow inside roller 16 remains constant, the airflow at the first hole 22 in contact with the galvanized steel plate is greater, increasing the airflow reaching the surface of the galvanized steel plate. After exiting the first hole 22, the airflow reaches the diverter plate 3 and flows along its surface. Because the diverter plate 3 has a wave-like structure, it reduces the airflow velocity, thereby increasing the contact time between the airflow and the galvanized steel plate. Simultaneously, the airflow exits from the second hole... 32 and the edge of the diverter plate 3 flow out, increasing the flow range of the airflow; when the ball 23 moves, it will drive the brush 4 to move together. When the brush 4 moves, it will contact the inner wall of the first round hole 22 and clean the inner wall of the first round hole 22, reducing the paint and other impurities remaining on the inner wall of the first round hole 22; after the equipment is started, the electric push rod 5 will also start and move the top plate 52 closer to the galvanized steel plate. The heating wire 54 will generate heat after being powered on. After the operator connects the second air inlet pipe 53 to the air pump, the air pump will deliver air into the second air inlet pipe 53. When the airflow passes through the heating wire 54, the heating wire 54 will heat the airflow. Then the hot airflow will reach the surface of the galvanized steel plate and dry the surface of the galvanized steel plate, accelerating the drying speed of the paint on the surface of the galvanized steel plate.When the airflow is ejected from the heating wire 54, it reaches the interior of the elastic cloth 6. The hot airflow flows inside the elastic cloth 6 and diffuses towards the galvanized steel sheet, allowing the hot airflow to flow more concentratedly onto the surface of the galvanized steel sheet. When the spraying assembly 17 sprays the galvanized steel sheet, splashed paint flows out from the fixing trough 18. This paint reaches the interior of the collection box 7 and is collected by the collection box 7, realizing the recycling and utilization of the paint by the equipment.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
