The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
The terms "first" and "second" in this specification do not denote a particular quantity or order, but rather are used to distinguish one element from another.
On the one hand, as shown in fig. 1 and 2, a horizontal spraying device in an embodiment of the present invention includes a spraying apparatus 1, a spraying cabinet 2, and a conveying chain 4 disposed through the spraying cabinet 2; the spraying equipment 1 comprises a spraying base 11 and a spray gun assembly 12 which can move up and down relative to the spraying cabinet body 2, wherein the spray gun assembly 12 performs spraying action on the aluminum profile fixed on the conveying chain 4; the spray gun assembly 12 includes a first nozzle set 121 and a second nozzle set 122 arranged in parallel, the first nozzle set 121 being disposed above the second nozzle set 122, the first nozzle set having a greater amount of powder 121 than the second nozzle set 122.
The horizontal spray device is provided with a first nozzle group 121 and a second nozzle group 122 which are arranged in parallel in the spray gun assembly 12, carrying out regional spraying on horizontally arranged aluminum profiles; meanwhile, the amount of powder sprayed by the first nozzle group 121 positioned above is larger than that of powder sprayed by the second nozzle group 122 positioned below, and the sinking powder of the first nozzle group 121 is deposited on the aluminum profile at the lower part by utilizing the powder spraying difference value of the first nozzle group 121 and the second nozzle group 122, so that the thickness of the coating powder of the aluminum profile at the lower part is prevented from exceeding the specification range, the coating is saved, and the rejection rate of the aluminum profile is reduced.
As shown in fig. 1, 2 and 3, in one embodiment, the device further includes a detecting component 3, where the detecting component 3 includes a controller 31 and a photoelectric switch 32, and the photoelectric switch 32 is used to detect a position of the delivery gun assembly 12 and send an electrical signal to the controller 31, and the controller 31 receives the electrical signal and then makes the amount of powder sprayed by the first nozzle set 121 reduce through electrical control. In this way, the position of the first nozzle group 121 in the spray gun assembly 12 is detected by the photoelectric switch 32, when the first nozzle group 121 reaches a specific position, the controller 31 reduces the powder spraying amount of the first nozzle group 121 through electrical control, for example, the first nozzle group 121 sprays normal powder amount corresponding to the upper part of the aluminum profile, when moving downwards, the powder sprayed by the first nozzle group 121 gradually reduces, the powder gradually sinking in the air adheres to the aluminum profile along with air flow by aerodynamic force generated when the first nozzle group 121 sprays, thereby reducing excessive sinking powder due to the spraying of the first nozzle group 121, and meanwhile, the sinking powder is used for supplementing the gradually reduced sprayed powder amount of the first nozzle group 121, so that the coating thickness of the surface of the aluminum profile is kept within the spraying specification.
As shown in fig. 4, in one of the embodiments, the conveyor chain 4 comprises a carriage 41 for hanging aluminium profiles, and the painting booth 2 comprises an auxiliary carriage 21, the auxiliary carriage 21 being arranged for tilting the carriage 41 within the painting booth 2 relative to a vertical plane towards the spray gun assembly 12. In this way, the spraying cabinet body 2 is inclined to the spray gun assembly 12 relative to the vertical surface through the conveying frame 41, when powder sprayed by the spray gun assembly 12 sinks, the sinking powder can sink on each horizontally placed aluminum profile, and therefore the situation that the upper surface of the horizontally placed aluminum profile is difficult to be covered by coating powder due to overlapping is avoided.
In one embodiment, the auxiliary frame 21 is a support frame provided with a plurality of guide wheels, the axes of which are inclined relative to the vertical towards the spray gun assembly 12. In this way, the guide wheels are utilized to enable the conveying frame 41 to incline, so that the aluminum profile horizontally placed on the conveying frame 41 is inclined, so that the aluminum profile is inclined relative to the spray gun assembly 12, when powder sprayed by the spray gun assembly 12 sinks, the sinking powder amount can sink on each horizontally placed aluminum profile, and therefore the situation that the upper surface of the horizontally placed aluminum profile is difficult to be covered by coating powder due to overlapping is avoided.
As shown in fig. 3, in one embodiment, the spray gun assembly 12 includes an air nozzle set 123 disposed between a first nozzle set 121 and a second nozzle set 122, the air nozzle set 123 spraying a gas and entraining a sinking powder through the aluminum profile by a gas flow created by the gas. Specifically, the injection timing of the air nozzle group 123 is staggered from the injection timing of the first nozzle group 121 and the second nozzle group 122. In this way, the air is sprayed through the air nozzle group 123, and the sinking powder is driven to pass through the aluminum profile by the air flow formed by the air, so that the sinking powder is prevented from being deposited on the aluminum profile below the air nozzle group 123.
In one embodiment, the spray coating device 1 comprises a first guide rail seat 13 and a second guide rail seat 14 arranged on the spray coating base 11, the first nozzle group 121 being arranged on the first guide rail seat 13 and the second nozzle group 122 being arranged on the second guide rail seat 14. In this way, the first nozzle group 121 and the second nozzle group 122 are separately and movably arranged, and the first nozzle group 121 and the second nozzle group 122 can be moved respectively, so that the spraying powder amount of the first nozzle group 121 and the second nozzle group 122 can be controlled conveniently, and the spraying time of the aluminum profile hung in the middle part of the conveying chain 4 is prevented from being longer than the spraying time of the aluminum profile at the upper part and the lower part.
In one embodiment, the spray base 11 is divided into a base upper portion, in which the first guide rail seat 13 moves, and a base lower portion, in which the second guide rail seat 14 moves, from top to bottom. Thus, by arranging the first nozzle group 121 and the second nozzle group 122 with separated upper and lower strokes, the spraying device 1 is convenient for carrying out regional spraying on the aluminum profile hoisted by the conveying chain 4.
As shown in fig. 5 and 7, in one embodiment, the spray gun assembly 12 includes an upper connecting rod set 15 and a lower hinge ear set 16 provided to the first guide rail seat 13, and a telescopic cylinder 17 hinged to the lower hinge ear set 16; one end of the upper connecting rod group 15 is connected with the first guide rail seat 13, and the other end is connected with the first nozzle group 121; the cylinder body of the telescopic cylinder 17 is hinged with the lower hinge lug group 16, and the telescopic rod end of the telescopic cylinder 17 is connected with the first nozzle group 121. In this way, the telescopic movement of the telescopic cylinder 17 is utilized to enable the first nozzle group 121 to perform angle adjustment relative to the first guide rail seat 13, so that the first nozzle group 121 can sufficiently spray the aluminum profile hoisted by the conveying chain 4, and the spraying blind area is reduced; meanwhile, since the spray tapered surface of the first nozzle group 121 is constant, the sinking position of the sinking powder can be controlled by adjusting the angle of the spray tapered surface.
In one embodiment, the bottom of the spray booth 2 is of an inclined configuration. Therefore, the inclined structure is arranged at the bottom of the spraying cabinet body 2, so that the sinking powder can be recycled conveniently.
As shown in fig. 6, in one embodiment, the horizontal spraying device includes a recovery assembly 5, the recovery assembly 5 including a first recovery mechanism 51 and a second recovery mechanism 52 connected to the first recovery mechanism 51; the first recovery mechanism 51 includes a recovery tower 511, a cyclone chamber 512 formed at an upper portion of the recovery tower 511, and a first collection tub 513 provided below the cyclone chamber 512; the lowest part of the inclined structure at the bottom of the spraying cabinet body 2 is provided with a first air outlet 20, and a first collecting barrel 513 is communicated with the first air outlet 20; the bottom of the cyclone separation chamber 512 is communicated with the first collecting barrel 513 through a dust outlet, the top of the recovery tower 511 is provided with an air inlet 5111 and an air outlet 5112, and the air inlet 5111 is connected to the second recovery mechanism 52 through a pipeline; the second recovery mechanism 52 includes a recovery chamber 521, a plurality of cartridges 522 provided in the recovery chamber 521, and a second collection tub 523 provided below the cartridges 522, which are sequentially connected. In this way, through the first recovery mechanism 51 and the second recovery mechanism 52, the powder-containing air from the spraying cabinet body 2 flows through the first air outlet 20 to enter the first recovery mechanism 51, large-particle dust in the air flow sinks into the first collecting drum 513 under the action of negative pressure and cyclone acceleration, the rest dust is recoiled upwards by the cyclone air flow, passes through the air duct and the second recovery mechanism 52, the dust air flow is filtered and adsorbed by the filter element 522 in the second recovery mechanism 52, and the filtered and adsorbed air is discharged into the atmosphere.
In one embodiment, the second recovery mechanism 52 includes a dust collection unit including a gas collection bag, a pulse solenoid valve mounted on the gas collection bag, and a rotary wing connected to the pulse solenoid valve, the pulse solenoid valve being located outside the recovery chamber 521, the rotary wings extending into the corresponding filter elements 522, respectively.
In one embodiment, the horizontal spray device further comprises a convection assembly 6, the convection assembly 6 comprising a first fan 61 disposed in a lower portion of the spray booth 2. In this way, the first fan 61 keeps the sinking powder in a suspended state or moves upward by blowing the air quantity upward.
In one embodiment, the convection assembly 6 further includes a second fan disposed at an upper portion within the spray booth 2 for spraying the first nozzle set 121 while the airborne powder is drawn out of the spray booth 2. Specifically, the second fan is started in the batch interval conveying time of the aluminum profiles conveyed by the conveying chain 4, and absorbs the suspended powder in the spraying cabinet body 2. Therefore, the powder suspended in the air in the spraying cabinet body 2 is sucked through the second fan, so that the powder suspended in the air in the spraying cabinet body 2 is prevented from increasing along with spraying time, and excessive spraying powder is attached to the surface of the aluminum profile conveyed into the spraying cabinet body 2.
In another aspect, a horizontal spray method includes the steps of:
s1, dividing spraying areas for aluminum profiles in a spraying cabinet body, arranging at least two groups of nozzles on a spray gun assembly moving up and down, and spraying different spraying areas. Specifically, the spray gun assembly comprises a first nozzle group and a second nozzle group which are arranged in parallel, wherein the first nozzle group is arranged above the second nozzle group, and the powder spraying amount of the first nozzle group is larger than that of the second nozzle group.
S2, adjusting the spraying powder quantity of the two groups of nozzles according to the sinking quantity of the powder sprayed by the spray gun assembly.
According to the horizontal spraying method, the horizontally arranged aluminum profiles are sprayed in the different areas by utilizing the spray gun assembly; meanwhile, by utilizing the powder spraying difference value of the spray gun assembly, the sinking powder sprayed by the first nozzle group above is deposited on the aluminum profile at the lower part, and the second nozzle group is sprayed with a small amount of spraying powder, so that the coating thickness of the aluminum profile at the lower part can reach the spraying specification, the coating is saved, and the problem that the rejection rate of the aluminum profile is reduced due to the fact that the coating powder thickness of the aluminum profile at the lower part exceeds the specification range is avoided.
Wherein, set up photoelectric switch in the spraying cabinet body, detect the position of spray gun subassembly, wait that the spray gun subassembly reaches the well lower part position of hoist and mount aluminum product, reduce the spraying powder volume of spray gun subassembly. Thus, the position of the first nozzle group in the spray gun assembly is detected through the photoelectric switch, when the first nozzle group reaches a specific position, the powder spraying amount of the first nozzle group is controlled to be reduced, for example, the first nozzle group sprays normal powder amount when corresponding to the upper part of the aluminum profile, when the first nozzle group moves downwards, the powder sprayed by the first nozzle group is gradually reduced, the powder gradually sinking in the air is attached to the aluminum profile along with air flow through aerodynamic force generated when the first nozzle group sprays, so that excessive sinking powder caused by the spraying of the first nozzle group is reduced, and meanwhile, the gradually reduced spraying powder amount of the first nozzle group is supplemented by the sinking powder, so that the coating thickness of the surface of the aluminum profile is kept within the spraying specification.
The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
