Specifically, as shown in fig. 13, in order to facilitate the sliding of the first and second sliding plates 410 and 420 in the sliding grooves 440, two pushing plates 600 are provided in the drying box 200, the two pushing plates 600 are respectively located at both sides of the conveyor belt 110, when the drying hood moves synchronously with the conveyor belt 110, the first and second sliding plates 410 and 420 on the drying hood pass through the pushing plates 600, inclined surfaces 610 are provided on one sides of the two pushing plates 600 near the conveyor belt 110, and when the drying hood moves synchronously with the conveyor belt 110, the pushing plates 600 push the first and second sliding plates 410 and 420 to compress the compression springs, so that the through grooves 430 on the first and second sliding plates 410 and 420 are staggered with each other to isolate the first and second spaces, resulting in the state of the first and second sliding plates 410 and 420 as shown in fig. 12.
In a further embodiment, as shown in fig. 9 and 10, the gas injection end 310 of the gas injection tube 300 is provided with a rotary nozzle 320, and the rotary nozzle 320 is rotatably connected, specifically hinged, to the gas injection end 310 of the gas injection tube 300, and the direction of the gas injection can be adjusted by rotating the rotary nozzle 320. The air jet pipe 300 is internally provided with an air vent plate 321, the air vent plate 321 can slide along the axis of the air jet pipe 300, a rack 323 is vertically arranged on one surface of the air vent plate 321 facing the rotating nozzle 320, the axis of the ball joint of the rotating nozzle 320 and the air jet end 310 of the air jet pipe 300 is provided with a gear shaft 324, the rotating nozzle 320 takes the gear shaft 324 as a rotating center, two ends of the gear shaft 324 are fixedly connected with the rotating nozzle 320, the gear shaft 324 is meshed with the rack 323, and when the air vent plate 321 moves axially in the air jet pipe 300, the rack 323 drives the rack 323 to move synchronously, and the gear shaft 324 rotates to drive the rotating nozzle 320.
For the convenience of connection, a ring plate 322 is disposed on the inner wall of the air nozzle 300, a through hole is disposed on the ring plate 322, a plurality of slide bars 325 are disposed on the air vent plate 321, the slide bars 325 extend into the through hole of the ring plate 322, one end of a tension spring (not shown in the figure) is sleeved on the slide bars 325 and fixedly connected with the ring plate 322, and the other end of the tension spring is fixedly connected with the air vent plate 321, so that the air vent plate 321 can move along the axial direction of the air nozzle 300.
It should be noted that, when the gas pressure in the gas jet 300 increases, the ventilation plate 321 is moved to the end close to the rotating nozzle 320, so as to drive the rack 323 to push the gear shaft 324 to rotate, the rotating nozzle 320 rotates to the upper left, i.e. clockwise in fig. 9, so that the intersection point of the gas jet 300 jetting out the gas flow moves upwards, it can be understood that after the gas pressure increases, the gas flow at the intersection point also increases, the distance between the intersection point and the surface of the metal part increases, and the influence of the excessive gas flow on the coating on the surface of the metal part can be avoided; when the gas pressure is reduced, the acting force of the gas received by the ventilation plate 321 is reduced, and the ventilation plate moves away from the rotating nozzle 320 under the action of the tension spring, so that the rotating nozzle 320 rotates leftwards and downwards, namely, the intersection point of the gas jet 300 jet air flow moves downwards in the anticlockwise direction in fig. 9, the distance between the intersection point and the surface of the metal part is reduced, and the drying effect of the surface coating of the metal part is ensured not to be influenced by the air pressure.
The following describes a specific working procedure of the integrated device for painting and drying metal parts according to the embodiment of the present application:
The conveyor belt 110 starts to run, metal parts are placed in the tray 120 on the conveyor belt 110, the metal parts firstly pass through the spraying box 130, the spraying mechanism in the spraying box 130 sprays the surfaces of the metal parts, and after spraying, the conveyor belt 110 conveys the metal parts into the drying box 200.
In the initial state, when the metal parts arrive below the third drying hood 230, the telescopic cylinder 510 of the third drying hood 230 is extended, so that the third drying hood 230 covers the two metal parts to start pre-drying, the first space and the second space of the third drying hood 230 are communicated through the staggered arrangement of the first sliding plate 410 and the second sliding plate 420, that is, the through grooves 430 on the first sliding plate 410 and the second sliding plate 420 are communicated with each other, the two pairs of air ejector pipes 300 are oppositely arranged, the air flows ejected by the two air ejector pipes 300 meet above the metal parts, the directions of the two air flows change when meeting, and thus the air flows are prevented from directly blowing to the surfaces of the metal parts to damage the coating, the temperature at the junction of the two air flows is higher, the coating on the surfaces of the metal parts is dried and shaped faster, and the drying efficiency is improved.
And secondary drying, when the third drying hood 230 moves to the push plate 600, the first sliding plate 410 and the second sliding plate 420 on the third drying hood 230 are pushed by the push plate 600, so that the first sliding plate 410 and the second sliding plate 420 slide in the sliding groove 440, the through grooves 430 on the first sliding plate 410 and the second sliding plate 420 are staggered to isolate the first space from the second space, and simultaneously, the connecting rod 460 on the first sliding plate 410 and the second sliding plate 420 drives one air jet 300 of each pair of air jets 300 to slide, so that the positions of the plurality of air jets 300 are staggered with each other, and the air flows of the air jets 300 are not converged any more, but are directly blown to the surface of the metal part to accelerate the drying of the coating, as in particular as in switching from fig. 7 to 12. The coating on the surface of the metal part at this time is shaped after being pre-dried, the secondary drying is directly blown to the coating, the positions of the air injection pipes 300 are staggered with each other, vortex is easy to generate, air flow is uniformly distributed in the first space or the second space, the surface of the metal part is uniformly dried, the telescopic cylinder 510 of the third drying cover 230 is shortened after the drying is finished, the third drying cover 230 is reset, the subsequent second drying cover 220 and the first drying cover 210 work alternately in sequence, the conveyer belt 110 continuously works, and the working efficiency is improved.
If the air pressure in the air ejector 300 is unstable, the speed of the air flow sprayed by drying is different, if the air pressure is increased, the air pressure in the air ejector 300 is increased, the air flow can push the air guide plate 321 to stretch the tension spring when passing through the air guide plate 321, so that the air guide plate 321 drives the rack 323 to move towards the direction close to the rotating spray head 320, the rack 323 drives the gear shaft 324 to rotate clockwise, and then the rotating spray head 320 is pushed to rotate left upwards, namely rotate clockwise, so that the intersection position of the air ejected by the two air ejector 300 is increased, the distance between the intersection position of the air and the surface of the metal part is increased, and further the influence of the excessive air flow on the drying and shaping of the surface coating of the metal part is avoided; if the air pressure in the air ejector 300 is reduced, when the air pressure in the air ejector 300 passes through the ventilation plate 321, the acting force pushing the ventilation plate 321 is reduced, the tension spring pulls the ventilation plate 321 to move away from the direction of the rotating spray head 320, the rack 323 is synchronously driven to move, the rack 323 pushes the gear shaft 324 to rotate anticlockwise, the intersection of the air ejector 300 moves downwards, the distance between the intersection position of the air flow and the surface of the metal part is reduced, and the flow speed of the air is reduced, so that the drying efficiency of the air flow to the surface of the part is reduced, the intersection position is closer to the surface of the part, and the drying efficiency is ensured not to be influenced by the air pressure.
