DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0023] like Figure 1 , Figure 2 and Figure 4 As shown, a galvanized steel plate surface coating equipment described in an embodiment of the present invention comprises a fixed machine base 1; a paint box 11 is fixedly connected to the side wall of the fixed machine base 1; a paint pump 12 is fixedly connected to the paint box 11; the output end of the paint pump 12 is fixedly connected to a fixed frame 13, and the fixed frame 13 is fixedly connected to the upper surface of the fixed machine base 1; both side ends of the fixed frame 13 are fixedly connected to delivery pipes 14; the ends of the two delivery pipes 14 away from the fixed frame 13 are fixedly connected to a coating box 15, and the coating box 15 can be connected to the output end of the coating pump 12 through the delivery pipe 14 and the fixed frame 13; when coating the galvanized steel plate surface, the fixed machine base 1 is used as the coating machine base. The main supporting frame of the zinc steel plate surface coating equipment places the galvanized steel plate vertically on the end of the fixed frame 13, and pushes the galvanized steel plate to slide in the middle of the fixed frame 13 to the middle of the two coating boxes 15. A large amount of paint is stored in the paint box 11, and the paint pump 12 draws the paint and sends it to the inside of the fixed frame 13. Then the paint circulates inside the fixed frame 13 and is sent to two delivery pipes 14 respectively. The paint finally reaches the two coating boxes 15 and is sprayed obliquely onto the sliding surface of the galvanized steel plate. The two coating boxes 15 evenly coat both sides of the galvanized steel plate, replacing the method of coating one side and then flipping over to continue spraying, thereby improving the efficiency of coating the galvanized steel plate surface.

[0024] like Figures 1 to 3 As shown, a servo motor 2 is fixedly connected to the outer wall of one side of the fixed base 1 close to the paint box 11; a push plate 21 is fixedly connected to the output end of the servo motor 2; a support bracket 22 is fixedly connected to the bottom outer wall of the push plate 21; when the surface of the galvanized steel plate is painted, the galvanized steel plate is first placed vertically on the push plate 21 and the fixed frame 13 at the same time, and the support bracket 22 is inserted into the inner wall of the fixed frame 13, and the support bracket 22 is used to limit the position during the sliding of the push plate 21 pushed by the servo motor 2 to ensure that the position of the galvanized steel plate is in a centered state. As the output end of the servo motor 2 drives the push plate 21 to push the galvanized steel plate to slide, the galvanized steel plate starts to be painted when it slides between the two painting boxes 15. After the push plate 21 is pushed to fit the outer wall of the fixed frame 13, the end of the galvanized steel plate that has been sprayed is pulled, and the remaining small part of the galvanized steel plate surface is sprayed and the material can be unloaded, which plays a role in spraying and conveying the galvanized steel plate.

[0025] The two sides of the pushing plate 21 are fixedly connected with support frames 3; the two support frames 3 are threadedly connected with threaded rods 31; the opposite ends of the two threaded rods 31 are rotatably connected to the limit plates 32; when the galvanized steel plate is sprayed and pushed, the two threaded rods 31 are first rotated and adjusted, and the threads between the threaded rods 31 and the support frames 3 are matched. According to the thickness of the galvanized steel plate currently being processed, the distance between the two limit plates 32 is adjusted so that the two limit plates 32 can fit the two sides of the galvanized steel plate. The galvanized steel plate is placed on the pushing plate 21 and is limited between the two limit plates 32 before starting to push, which plays the role of limiting the center of the galvanized steel plate.

[0026] like Figure 1 , Figure 2 and Figure 4 As shown, the outer walls of the two coating boxes 15 are fixed with magnetic blocks 4; the inner walls of the magnetic blocks 4 are slidably connected with magnetic bars 41, and the magnetic blocks 4 and the magnetic bars 41 can be magnetically attracted; a baffle plate 42 is fixedly connected to the magnetic bars 41, and the baffle plate 42 can be slidably connected to the inner wall of the coating box 15; when galvanized steel plates of different widths are painted, the positions of the two magnetic bars 41 are slidably adjusted according to the width of the galvanized steel plates, the magnetic bars 41 slide on the inner walls of the magnetic blocks 4, and the baffle plate 42 also blocks part of the spray holes of the coating box 15 as the magnetic bars 41 slide. After the position adjustment of the magnetic bars 41 is completed, the magnetic blocks 4 adsorb and fix the magnetic bars 41 to limit the position, thereby adjusting the spray range of the coating box 15 according to the galvanized steel plates of different widths.

[0027] like Figures 1 to 4 As shown, two fixed blocks 5 are fixedly connected to the outer wall of one side of the fixed frame 13 away from the coating box 15; sliding rods 51 are slidably connected to the two fixed blocks 5; scraper plates 52 are fixedly connected to the opposite ends of the two sliding rods 51; a matching component is provided on the fixed block 5, and the matching component is used to cooperate with the scraper plates 52 to treat the surface of the galvanized steel plate; when the galvanized steel plate is conveyed and coated, since impurities adhere to the surface of some galvanized steel plates, it is easy to affect the coating effect of the galvanized steel plates, and the two fixed blocks 5 are respectively fixed to the outer walls of the protruding parts on both sides above the fixed frame 13, and the sliding rod 51 slides through the inside of the fixed block 5. According to the thickness of the galvanized steel plate, the sliding rod 51 is limited on the fixed block 5 by the matching component, so that the two scraper plates 52 can fit the two side surfaces of the galvanized steel plate. As the galvanized steel plate is conveyed, the two scraper plates 52 scrape the surface of the galvanized steel plate, reduce the attachment of impurities on the surface of the galvanized steel plate, and improve the coating effect on the surface of the galvanized steel plate.

[0028] The fixed block 5 and the sliding rod 51 are both provided with circular holes, and the fixed block 5 is provided with one circular hole, and the sliding rod 51 is provided with multiple circular holes; the mating components include an insertion rod 6 and friction cotton 61; the insertion rod 6 is inserted into the fixed block 5, and the insertion rod 6 passes through the sliding rod 51; the friction cotton 61 is fixedly connected to the side of the scraper plate 52 away from the fixed block 5; when the distance between the two scraper plates 52 is adjusted, the two sliding rods 51 are slid respectively, and after adjusting the distance between the two scraper plates 52 according to the thickness of the galvanized steel plate, the insertion rod 6 is used to insert the circular hole of the fixed block 5, and the insertion rod 6 passes through the circular hole of the sliding rod 51 to fix the position of the sliding rod 51, which plays a role in limiting the position of the scraper plate 52. As the galvanized steel plate is transported, the friction cotton 61 adheres to the surface of the galvanized steel plate and wipes it, reducing the residual impurities on the surface of the galvanized steel plate.

[0029] like Figures 1 to 3 As shown, the outer walls of the two scraper plates 52 are fixedly connected with a fixed plate 7; the inner walls of the fixed plates 7 are slidably connected with a grinding block 71; a sliding groove is provided on the fixed plate 7; a connecting rod 72 is fixedly connected to the grinding block 71, and the connecting rod 72 slides in the sliding groove; a transmission assembly is provided on the fixed machine base 1, and the transmission assembly is used to drive the connecting rod 72 to slide back and forth; before the galvanized steel plate is painted, the surface of the galvanized steel plate needs to be polished, and the two fixed plates 7 are respectively fixed on the two scraper plates 52, and the transmission assembly is driven to operate during the sliding of the support bracket 22, and the transmission assembly drives the connecting rod 72 to slide back and forth, so that the grinding block 71 fixed to the connecting rod 72 polishes the surface of the galvanized steel plate up and down, thereby realizing the effect of synchronous polishing during the transportation of the galvanized steel plate.

[0030] The transmission assembly includes a support plate 8, a gear 81, a crank 82 and a connecting plate 83; the two support plates 8 are fixedly connected to the upper surface of the fixed machine base 1, and a rotating rod is rotatably connected to the two support plates 8; a rack is fixedly connected to the bottom end of the support bracket 22; the gear 81 is fixedly connected to the middle outer wall of the rotating rod, and the gear 81 and the rack are meshed with each other; the two cranks 82 are respectively fixedly connected to the two ends of the rotating rod; the connecting plate 83 is hinged between the connecting rod 72 and the crank 82; when the galvanized steel plate is transported, the gear 81 on the two support plates 8 supporting the rotating rod is at the bottom of the support bracket 22, and the rack at the bottom end of the support bracket 22 is meshed with the gear 81. As the support bracket 22 slides and drives the gear 81 to rotate, the two cranks 82 at both ends of the rotating rod rotate accordingly. During the rotation of the crank 82, the connecting rod 72 connected to the connecting plate 83 is driven to slide up and down, thereby driving the grinding block 71 to reciprocate and grind the galvanized steel plate.

[0031] like Figure 1 and Figure 5As shown, a heating box 9 is fixedly connected to the outer wall of one side of the fixed machine base 1 close to the paint box 11; a drying plate 91 is fixedly connected to the upper surface of the fixed machine base 1, and the output end of the heating box 9 is connected to the drying plate 91; when both sides of the galvanized steel plate are painted, the heating box 9 is used to generate hot air, and the hot air is sent to the inside of the drying plate 91 through the output end of the heating box 9, and the surface of the galvanized steel plate passing through is dried by the air outlet opposite to the drying plate 91, which plays a role in curing the paint.

[0032] like Figure 1 , Figure 2 and Figure 5 As shown, the interior of the fixed machine base 1 is slidably connected to a sliding plate 92 through an electric slider; a suction cup frame 93 is fixedly connected to one end of the sliding plate 92 away from the fixed machine base 1, and a plurality of suction cups are arranged on the side of the suction cup frame 93 close to the fixed machine base 1; a vacuum pump 94 is fixedly connected to the outer wall of the suction cup frame 93, and the output end of the vacuum pump 94 is connected to a plurality of suction cups; when the galvanized steel sheet is conveyed and painted, the pushing plate 21 cannot continue to push the galvanized steel sheet after pushing it to the outer wall of the fixed frame 13, and the tail of the galvanized steel sheet has not been painted at this time. The electric slider is used to drive the sliding plate 92 to slide inside the fixed machine base 1, so that the suction cup frame 93 is in contact with the head of the galvanized steel sheet, and the vacuum pump 94 cooperates with the plurality of suction cups to vacuum adsorb the head of the galvanized steel sheet, and the head of the galvanized steel sheet after the paint is dried is pulled and slid until the tail of the galvanized steel sheet is painted and dried and then unloaded, thereby improving the painting effect on the surface of the galvanized steel sheet.

[0033] Working process: when painting the surface of the galvanized steel plate, the fixed machine base 1 is used as the main supporting frame of the galvanized steel plate surface painting equipment, and the galvanized steel plate is vertically placed on the end of the fixed frame 13, and the galvanized steel plate is pushed to slide in the middle of the fixed frame 13 to the middle of the two painting boxes 15. A large amount of paint is stored inside the paint box 11, and the paint pump 12 extracts the paint and sends it to the inside of the fixed frame 13. Then the paint circulates inside the fixed frame 13 and is sent to the two delivery pipes 14 respectively. The paint finally reaches the two painting boxes 15 and is sprayed obliquely onto the sliding surface of the galvanized steel plate. The two painting boxes 15 evenly paint both sides of the galvanized steel plate, replacing the method of coating one side and then flipping over to continue spraying, thereby improving the efficiency of painting the surface of the galvanized steel plate; when painting the surface of the galvanized steel plate, the galvanized steel plate is first placed vertically on the pushing plate 21 and the fixed frame 13 at the same time, and the support bracket 22 is inserted into the inner wall of the fixed frame 13. The support bracket 22 is used to control the servo During the sliding process of the pushing plate 21 pushed by the motor 2, the limit is ensured to ensure that the position of the galvanized steel plate is in the center state. As the output end of the servo motor 2 drives the pushing plate 21 to push the galvanized steel plate to slide, the galvanized steel plate starts to be painted when it slides between the two painting boxes 15. Until the pushing plate 21 is pushed to fit the outer wall of the fixing frame 13, the end of the galvanized steel plate that has been sprayed is pulled, and the remaining small part of the galvanized steel plate surface is sprayed and unloaded, which plays the role of spraying and conveying the galvanized steel plate; when the galvanized steel plate is sprayed and pushed, the two threaded rods 31 are first rotated and adjusted, and the threaded rods 31 and the support frame 3 are threadedly matched. According to the thickness of the galvanized steel plate currently processed, the distance between the two limit plates 32 is adjusted so that the two limit plates 32 can fit the two sides of the galvanized steel plate. The galvanized steel plate is placed on the pushing plate 21 and is limited between the two limit plates 32. Pushing starts, which plays the role of limiting the center of the galvanized steel plate; When galvanized steel sheets of different widths are painted, the positions of the two magnetic bars 41 are slidably adjusted according to the width of the galvanized steel sheets. The magnetic bars 41 slide on the inner wall of the magnetic block 4, and the shielding plate 42 also slides with the magnetic bars 41 to block part of the spray holes of the paint box 15. After the position adjustment of the magnetic bars 41 is completed, the magnetic block 4 adsorbs and fixes the magnetic bars 41, thereby adjusting the spray range of the paint box 15 according to the galvanized steel sheets of different widths. When the galvanized steel sheet is conveyed and coated, since impurities adhere to the surface of some galvanized steel sheets, it is easy to affect the coating effect of the galvanized steel sheet. Two fixed blocks 5 are respectively fixed on the outer walls of the protruding parts on both sides above the fixed frame 13, and the sliding rod 51 slides through the inside of the fixed block 5. According to the thickness of the galvanized steel sheet, the sliding rod 51 is limited on the fixed block 5 by the matching component, so that the two scraper plates 52 can fit the surfaces of both sides of the galvanized steel sheet. As the galvanized steel sheet is conveyed, the two scraper plates 52 scrape the surface of the galvanized steel sheet to reduce the surface of the galvanized steel sheet. Impurities attached to the surface are improved to improve the coating effect on the surface of the galvanized steel plate; when adjusting the distance between the two scraper plates 52, slide the two sliding rods 51 respectively, and after adjusting the distance between the two scraper plates 52 according to the thickness of the galvanized steel plate, use the insertion rod 6 to insert the round hole of the fixed block 5, and the insertion rod 6 passes through the round hole of the sliding rod 51 to fix the position of the sliding rod 51, which plays a role in limiting the position of the scraper plate 52. As the galvanized steel plate is transported, the friction cotton 61 is attached to the surface of the galvanized steel plate and wiped, reducing the impurities remaining on the surface of the galvanized steel plate; Before the galvanized steel sheet is coated, it is necessary to grind the surface of the galvanized steel sheet. The two fixed plates 7 are respectively fixed on the two scraper plates 52. As the support bracket 22 slides, the transmission assembly is driven to operate. The transmission assembly drives the connecting rod 72 to slide back and forth, so that the grinding block 71 fixed to the connecting rod 72 grinds the surface of the galvanized steel sheet up and down, thereby realizing the effect of synchronous grinding during the transportation of the galvanized steel sheet; when the galvanized steel sheet is transported, the two support plates 8 support the gear 81 on the rotating rod to be at the bottom of the support bracket 22, and the rack at the bottom end of the support bracket 22 is meshed with the gear 81. As the support bracket 22 slides and drives the gear 81 to rotate, the two cranks 82 at both ends of the rotating rod rotate accordingly. During the rotation of the crank 82, the connecting rod 72 connected to the connecting plate 83 is driven to slide up and down, thereby driving the grinding block 71 to grind the galvanized steel sheet reciprocatingly; After both sides of the galvanized steel sheet are painted, the heating box 9 generates hot air, which is sent to the inside of the drying plate 91 through the output end of the heating box 9. The air outlets opposite to the drying plate 91 dry the surface of the galvanized steel sheet passing through, thereby curing the paint. When the galvanized steel sheet is being conveyed and painted, the pushing plate 21 cannot continue to push the galvanized steel sheet after it is pushed to the outer wall of the fixing frame 13. The tail of the galvanized steel sheet has not been painted at this time. The electric slider is used to drive the sliding plate 92 to slide inside the fixed machine base 1, so that the suction cup frame 93 fits the head of the galvanized steel sheet. The vacuum pump 94 cooperates with multiple suction cups to vacuum adsorb the head of the galvanized steel sheet, and the head of the galvanized steel sheet after the paint is dried is pulled and slid until the tail of the galvanized steel sheet is painted and dried and then unloaded, thereby improving the painting effect on the surface of the galvanized steel sheet.
