Description

Technical Field

[0001] The invention relates to the technical field of aluminum plate spraying, and in particular to a spraying device for aluminum plate processing. Background Art

[0002] During the processing of aluminum plates, electrostatic powder spraying is usually used to spray primer. The working principle of electrostatic powder spraying is almost the same as that of general liquid coating electrostatic spraying, except that powder spraying is dispersed rather than atomized. It is a coating sprayed by an electrostatic powder spray gun. While dispersing, the powder particles are negatively charged. The charged powder particles are attached to the grounded object under the action of airflow (or other forces such as centrifugal force) and electrostatic attraction, and then heated, melted and solidified into a film. Electrostatic powder spraying is a powder coating method that occupies a dominant position in the field of industrial coating. During the electrostatic spraying process of aluminum plates, when the coating reaches a certain thickness, due to the limitation of electrostatic adsorption force, the additional powder coating can no longer be adsorbed on the surface of the aluminum plate, but can only slide off.

[0003] A high-voltage electrostatic spraying machine is disclosed in a Chinese patent document with authorization announcement number CN112295766B. The high-voltage electrostatic spraying machine can solve the problem that the existing equipment cannot effectively and accurately adjust the on and off of the high-voltage electricity during use, resulting in the plate still having voltage after spraying. When the sprayed parts are removed manually, it is easy to affect the safety of the workers. At the same time, the existing equipment is usually unable to effectively spray the paint on the parts to be processed during use, and cannot accurately adjust the distance between the nozzle and the parts, affecting the spraying effect of the parts.

[0004] However, the structural design of the above-mentioned related technology is as follows: when spraying an aluminum plate with a groove, since the side edge of the groove on the aluminum plate is in the same straight line with the spray gun, the powder sprayed by the spray gun will be attracted by other parts of the aluminum plate, resulting in the side edge of the groove of the aluminum plate cannot be effectively sprayed; if the spray angle of the spray gun is adjusted to reciprocately spray the aluminum plate, the surface outside the groove of the aluminum plate will be sprayed multiple times, resulting in a waste of paint.

[0005] Therefore, a spraying device for aluminum plate processing is proposed to solve the above-mentioned problems. Summary of the invention

[0006] The invention provides a spraying device for aluminum plate processing, aiming to solve the problem in the related art that multiple spraying easily leads to paint waste.

[0007] The spraying device for aluminum plate processing of the present invention comprises a conveyor, a hoisting mechanism and a spraying mechanism, wherein the hoisting mechanism is slidably arranged on the conveyor, and the hoisting mechanism comprises a mounting seat, two adjustment components mounted on the mounting seat, and three hoisting components arranged at the bottom of the mounting seat and used for hoisting workpieces, wherein the adjustment components are used to drive the two hoisting components located on the left and right to move relative to the hoisting component located in the middle, thereby changing the stacking state of the three workpieces; The spraying mechanism comprises a fixed seat and a plurality of spray guns distributed in a vertical direction, wherein a sliding assembly for controlling the spray guns to move in a left-right direction is installed on the fixed seat; When the spray gun moves to the right along the fixed seat, among every two adjacent workpieces, the straight surface of the right end of the left workpiece is covered by the straight surface of the left end of the right workpiece. When the spray gun moves to the left along the fixed seat to the end, among every two adjacent workpieces, the straight surface of the left end of the right workpiece is covered by the straight surface of the right end of the left workpiece.

[0008] Beneficial effect: The conveyor drives the workpiece to the initial spraying position of the spray gun through the hoisting assembly. At this time, the spray gun moves to the right and sprays half of the workpiece surface first. After the spray gun sprays the workpiece on the rightmost end, the adjustment assembly adjusts the positions of the left and right workpieces through the hoisting assembly. At the same time, the spray gun rotates and changes the spraying direction to spray the other half of the workpiece surface, thereby improving the spraying effect of the workpiece groove and achieving the effect of comprehensive spraying of the workpiece. In addition, during the spraying process, it can avoid waste of paint and reduce processing costs.

[0009] Preferably, the adjustment assembly includes a rotating shaft 1 rotatably connected to the inner bottom wall of the mounting seat, a push plate installed on the rotating shaft 1 and a movable column located in the push plate, limiting grooves are provided on both sides of the bottom of the mounting seat, a sliding groove is provided on the push plate, the movable column is located in the sliding groove of the push plate, the movable column is slidably connected in the limiting groove, and the movable column is installed on a lifting assembly located on one side of the bottom of the mounting seat.

[0011] The effect is that the clamping column, the connecting plate and the plurality of hooks can be easily removed through the clamping connection between the clamping column and the connecting seat, so as to facilitate replacement or maintenance.

[0012] Preferably, a driving assembly is provided on the top of the mounting seat, and the driving assembly includes a connecting shaft rotatably connected to the mounting seat, a gear installed on the connecting shaft, and a second rotating shaft installed at the bottom end of the connecting shaft, the bottom end of the second rotating shaft is rotatably connected to the inner bottom wall of the mounting seat, the second rotating shaft is transmission-connected to the first rotating shaft, and a rack is installed at the bottom of the conveyor, and the gear can engage with the rack.

[0013] The effect is that after the spray gun has finished spraying the workpiece at the end, the conveyor drives the mounting seat to move. At this time, the gear on the mounting seat starts to rotate under the action of the rack, and the gear drives the rotating shaft 1 to rotate through the rotating shaft 2 on the connecting shaft. The rotating shaft 1 can drive the movable column to slide along the trajectory of the limiting groove through the push plate, thereby exchanging the positions of the two workpieces at the edge to expose the unsprayed area of ​​the workpiece.

[0014] Preferably, the sliding assembly comprises an electric slide rail installed inside a fixing seat, and an electric slider is slidably connected to the electric slide rail.

[0015] The effect is that the electric slide rail can drive the spray gun to move back and forth along the length direction of the fixed seat through the electric slide block, so as to perform reciprocating spraying on the workpiece.

[0018] The effect is that when the rotating column moves, the adjustment plate contacts the limiting plate 2. At this time, under the action of the limiting plate 2, the adjustment plate drives the spray gun to rotate through the rotating column, so that the angle of the spray gun is opposite to the angle at the initial position, so as to adjust the spraying direction of the spray gun.

[0019] Preferably, connecting columns are installed on both sides of the top of the mounting seat, and the connecting columns are slidably connected to the bottom of the conveyor.

[0020] By adopting the above technical scheme, the beneficial effects of the present invention are as follows: during spraying, the spray gun moves to the right and first sprays half of the workpiece surface. After the spray gun sprays the rightmost workpiece, the adjustment component adjusts the positions of the left and right workpieces through the lifting component. At the same time, the spray gun rotates and changes the spraying direction to spray the other half of the workpiece surface, thereby improving the spraying effect on the workpiece groove and achieving the effect of comprehensive spraying of the workpiece. In addition, during the spraying process, it is possible to avoid waste of paint and reduce processing costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0028] like Figures 1 to 5As shown, the spraying device for aluminum plate processing of the present invention comprises a conveyor 1, a hoisting mechanism 2 and a spraying mechanism 3. The conveyor 1 is a chain conveying device, and there are three hoisting mechanisms 2. The three hoisting mechanisms 2 are all arranged on the conveyor 1, and three workpieces are hoisted on each hoisting mechanism 2. The workpiece has a groove and two straight surfaces. There is a spacing between each two adjacent workpieces to prevent the workpieces from contacting each other and causing the paint to fall. In the initial state, in each two adjacent workpieces, the straight surface of the right end of the left workpiece is covered on the straight surface of the left end of the right workpiece. The spraying mechanism 3 is located below one side of the conveyor 1. The conveyor 1 drives the workpiece to be transported to the initial spraying position of the spraying mechanism 3 through the hoisting mechanism 2. At this time, the spraying mechanism 3 sprays the workpiece on the hoisting mechanism 2. During the spraying process, the straight surface of the left end of the right workpiece in each two adjacent workpieces is covered on the straight surface of the right end of the left workpiece through the hoisting mechanism 2, so as to achieve the effect of alternating spraying of the straight surfaces of the workpieces and avoid waste of paint.

[0029] like Figures 1 to 3 As shown, the hoisting mechanism 2 includes a mounting seat 21 , a hoisting assembly 22 , a driving assembly 23 , a connecting column 24 and two adjustment assemblies 25 . There are two connecting columns 24, which are respectively mounted on both sides of the top of the mounting seat 21. The connecting columns 24 are slidably connected to the bottom of the conveyor 1. There are three hanging components 22. The hanging component 22 located in the middle is mounted on the bottom of the mounting seat 21, and the hanging components 22 located on the left and right sides are respectively slidably set at the bottom of the mounting seat 21. The workpiece is hung on the hanging component 22, and the driving component 23 is set on the top of the mounting seat 21. The two adjusting components 25 are respectively rotatably connected to both sides of the inner bottom wall of the mounting seat 21, and the hanging components 22 located on the left and right sides are respectively set on the two adjusting components 25. In the initial position, the two hanging components 22 located on the left and right sides are diagonally arranged, and the driving component 23 is transmission-connected to the two adjusting components 25. The driving component 23 can drive the two adjusting components 25 to rotate, so that the hanging components 22 on both sides of the bottom of the mounting seat 21 can be adjusted to change the stacking state of the three workpieces.

[0030] like Figures 1 to 4As shown, the adjustment assembly 25 includes a rotating shaft 251, a transmission wheel 252, a push plate 253 and a movable column 254. The rotating shaft 251 is rotatably connected to the inner bottom wall of the mounting seat 21, and a limiting groove 26 is provided at the bottom of the mounting seat 21 near the outer side of the rotating shaft 251. In this embodiment, the limiting groove 26 is in a U shape. The transmission wheel 252 is installed at the outer side of the top end of the rotating shaft 251, and the push plate 253 is installed at the outer side of the bottom end of the rotating shaft 251. The top of the push plate 253 is provided with a sliding groove that penetrates the push plate 253. The movable column 254 is located in the sliding groove of the push plate 253. In this embodiment, the movable column 254 is in a T shape. The bottom end of the movable column 254 is slidably connected to the limiting groove 26, and the bottom end of the movable column 254 is installed on the hoisting assembly 22 located at one side of the bottom of the mounting seat 21.

[0031] When the rotating shaft 251 on the two adjustment components 25 rotates, the rotating shaft 251 can drive the movable column 254 to slide along the track of the limiting groove 26 through the push plate 253, so that the positions of the two movable columns 254 can be adjusted to adjust the positions of the hanging components 22 on both sides of the bottom of the mounting seat 21, so that in every two adjacent workpieces, the straight surface of the left end of the right workpiece is covered by the straight surface of the right end of the left workpiece.

[0032] like Figures 1 to 3 As shown, the hoisting assembly 22 includes a connection seat 221, a clamping column 222, a connection plate 223 and a hook 224. The clamping column 222 is clamped inside the connection seat 221, the connection plate 223 is installed at the bottom end of the clamping column 222, and the number of hooks 224 is multiple. In this embodiment, the number of hooks 224 is two, and in other embodiments, the number of hooks 224 can be three, four or more. The hook 224 is installed at the bottom of the connection plate 223, and the workpiece is hung at the end of the hook 224.

[0033] The connecting seats 221 in the hanging components 22 located on both sides of the bottom of the mounting seat 21 are respectively installed at the bottom ends of the two movable columns 254 , and the connecting seat 221 in the hanging component 22 located in the middle is installed in the middle of the lower surface of the mounting seat 21 .

[0034] When the position of the movable column 254 is adjusted, the connection seat 221 connected to the movable column 254 drives the workpiece on the hook 224 to move through the connection plate 223 on the clamping column 222, so that the covered surface of the workpiece can be replaced.

[0035] like Figure 2 and Figure 4As shown, the driving assembly 23 includes a connecting shaft 231, a gear 232 and a second rotating shaft 233. The bottom end of the connecting shaft 231 is rotatably connected to the top of the mounting seat 21, the gear 232 is installed at the top of the connecting shaft 231, a rack 235 is installed on one side of the bottom of the conveyor 1, when the workpiece moves to the spraying range of the spraying mechanism 3, the gear 232 can mesh with the rack 235, the second rotating shaft 233 is installed at the bottom end of the connecting shaft 231, and the bottom end of the second rotating shaft 233 passes through the top of the mounting seat 21 and is rotatably connected to the inner bottom wall of the mounting seat 21. A second transmission wheel 234 is installed on the outer side of the second rotating shaft 233. In the present embodiment, the first transmission wheel 252 and the second transmission wheel 234 are both pulleys, and the second transmission wheel 234 and the two first transmission wheels 252 are connected by belt transmission. In other embodiments, the first transmission wheel 252 and the second transmission wheel 234 are both sprockets, and the second transmission wheel 234 and the two first transmission wheels 252 are connected by chain transmission.

[0036] After the spraying mechanism 3 sprays one of the straight surfaces on all the workpieces, the spraying mechanism 3 adjusts the spraying angle, and at the same time, the conveyor 1 drives the mounting seat 21 to move through the connecting column 24. At this time, under the action of the rack 235, the rack 235 drives the rotating shaft 233 on the connecting shaft 231 to rotate through the gear 232, and the rotating shaft 233 drives the rotating shaft 1 251 to rotate to adjust the position of the workpiece, so that the spraying mechanism 3 can spray the other straight surface on the workpiece and the other half of the area of ​​the workpiece groove.

[0037] like Figure 1 and Figure 5 As shown, the spraying mechanism 3 includes a fixed seat 31, a sliding assembly and a spraying assembly 34. The fixed seat 31 is located below one side of the conveyor 1, and the sliding assembly includes an electric slider 32 and an electric slide rail 33. The electric slide rail 33 is installed on the inner bottom wall of the fixed seat 31, and the electric slider 32 is slidably connected to the top of the electric slide rail 33. The spraying assembly 34 is rotatably connected to the top of the electric slider 32. The electric slide rail 33 can drive the spraying assembly 34 to move along the length direction of the fixed seat 31 through the electric slider 32 to spray all workpieces.

[0038] Continue to refer Figure 1 and Figure 5As shown, the spray assembly 34 includes a rotating column 341, a mounting frame 342 and a spray gun 343. The bottom end of the rotating column 341 is rotatably connected to the top of the electric slider 32, the top of the fixed seat 31 is provided with a groove for the sliding movement of the rotating column 341, and the bottom of the mounting frame 342 is installed on the top of the rotating column 341. There are multiple spray guns 343, and the multiple spray guns 343 are arranged at equal intervals along the height direction of the mounting frame 342. The spray gun 343 is provided with a solenoid valve to control the opening and closing of the spray gun 343. The end of the spray gun 343 is used to connect the paint delivery pipeline and the high-voltage electrostatic generator. In the initial position, the spray gun 343 is tilted so that the spray gun 343 can spray half of the area of ​​the groove on the workpiece.

[0039] like Figure 5 As shown, an adjustment plate 344 is installed on the outer side of the rotating column 341, and a limit plate 35 is installed on one side of the top of the fixed seat 31. In the initial position, the adjustment plate 344 is in contact with the limit plate 35, and a limit plate 2 36 is installed on the other side of the top of the fixed seat 31. The limit plate 1 35 and the limit plate 2 36 are perpendicular to each other.

[0040] Working principle: first hang the workpiece on the hook 224, and then, driven by the conveyor 1, move the workpiece to the spraying range of the spray gun 343, at which time the rack 235 is meshed with the gear 232. Then start the electric slide 33, which drives the spray gun 343 on the mounting frame 342 to move to the right through the rotating column 341 on the electric slide 32. During the movement, the spray gun 343 sprays a straight surface of the workpiece and half of the area of ​​the workpiece groove. After the spray gun 343 has finished spraying the workpiece at the right end, the spray gun 343 is closed. At this time, the spray gun 343 continues to move so that the adjustment plate 344 on the rotating column 341 contacts the limit plate 2 36, and under the restriction of the limit plate 2 36, the adjustment plate 344 drives the spray gun 343 to rotate through the rotating column 341, so that the angle of the spray gun 343 is opposite to the angle at the initial position.

[0041] During the process of adjusting the angle of the spray gun 343, the conveyor 1 drives the mounting seat 21 to move through the connecting column 24. At this time, the gear 232 on the mounting seat 21 starts to rotate under the action of the rack 235. The gear 232 drives the rotating shaft 1 251 to rotate through the rotating shaft 2 233 on the connecting shaft 231. The rotating shaft 1 251 can drive the movable column 254 to slide along the track of the limiting groove 26 through the push plate 253, thereby adjusting the positions of the left and right workpieces, so that the unsprayed straight surface of the workpiece is exposed and the sprayed straight surface of the workpiece is hidden. When the position adjustment of the workpiece is completed, the conveyor 1 stops conveying, and At this time, the gear 232 is disengaged from the rack 235, and then the electric slide rail 33 drives the spray gun 343 to move to the left to spray the unsprayed straight surface of the workpiece and the other half of the workpiece groove, so as to achieve the effect of comprehensive spraying of the workpiece, and in the process of spraying, it can save paint and avoid waste of paint. When all workpieces are sprayed, the spray gun 343 is closed and returns to the initial position. During the resetting process of the spray gun 343, the adjustment plate 344 on the rotating column 341 contacts the limit plate 35. At this time, under the action of the limit plate 35, the adjustment plate 344 is reset, thereby resetting the spray gun 343.

[0042] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
