[0020] An adjustment plate 14 is hinged in the protective cover 2, and the adjustment plate 14 can rotate along the hinge point. Adjustment rods 15 are provided at both ends of the adjustment plate 14. A slider 16 is protruded from one end of the adjustment rod 15 away from the adjustment plate 14, and the slider 16 slides in an adjustment slot 17 provided on the mounting plate 6; a cylinder 18 is connected to one of the mounting plates 6 to control its up and down movement. During operation, the mounting plate 6 connected to it is driven to rise or fall by the extension and contraction of the cylinder 18, and the adjustment plate 14 can be driven to rotate along the hinge point by the adjustment rod 15 by the lever principle, thereby driving the other mounting plate 6 to fall or rise, thereby realizing the synchronous one-rise and one-fall operation of the two mounting plates 6, meeting the interval separation spraying of different colors of paint, which can not only prevent the phenomenon of cross contamination caused by the simultaneous spraying of different colors of paint, but also can make the paint of the previous color dry to a certain extent under the action of the heating equipment when spraying the next color of paint, so as to avoid the adverse effect on the sprayed paint surface due to the high humidity of the sprayed paint surface when spraying the next paint.

[0021] The bottom of the mounting plate 6 is detachably provided with a threaded screw 19, which is preferably provided on a support frame 20. The mounting plate 6 is connected to the support frame 20 by a thread, and is indirectly connected to the threaded screw 19 so as to facilitate the subsequent maintenance and replacement of the threaded screw 19; a plurality of sliders 21 are provided on the threaded screw 19, and adjacent sliders 21 are movably connected by a hinge plate 24 so as to achieve equidistant adjustment between different sliders 21, thereby completing the distance adjustment between the nozzles to meet different spraying requirements; the partition cover 9 is detachably provided on the slider 21, which is convenient for the maintenance and replacement of the partition cover 9, or the replacement of partition covers 9 of different sizes, so as to meet the spraying operation of flat irons of different widths and lengths. In addition, in this embodiment, guide rods 22 are also provided in parallel on the support frames 20 on both sides of the threaded screw 19, and the sliders 21 are slidably connected to the guide rods 22 to ensure the stability of the sliders 21 when they move. The threaded screw 19 in this embodiment can be driven by a motor provided at the end of the support frame 20.

[0022] Furthermore, a mounting rod 23 is provided on the roller conveyor 1, and the mounting rod 23 is arranged parallel to the rollers on the roller conveyor 1. A spacing-adjustable limiting plate 25 is symmetrically provided on the mounting rod 23, and a clearance opening is provided at the position corresponding to the roller on the limiting plate 25 to prevent the limiting plate 25 from being restricted when adjusting; by adjusting the spacing between the two limiting plates 25, the flat iron can be limited to be directly below the nozzle to avoid the flat iron from being offset during movement, resulting in spraying failure. Specifically, each mounting rod 23 is provided with a fixing groove 26 along its length direction, and a limiting tooth 27 is provided in the fixing groove 26. A positioning groove 28 is provided on the outside of each limiting plate 25, and a positioning tooth plate 29 is elastically provided in the positioning groove 28. The positioning plate 25 can be positioned by meshing the positioning tooth plate 29 with the limiting tooth 27 to ensure the stability of the position of the limiting plate 25; when adjusting, it is only necessary to pull up the positioning tooth plate 29 to disengage it from the limiting tooth 27.

[0023] A groove is provided on the limit plate 25 in the protective cover 2, and a plurality of push plates 30 are slidably arranged in the groove. The sliding adjustment of the push plates 30 can adjust their positions, so that when the flat irons of different lengths are used, their positions can be adjusted so that they can always contact with the sealing plates 31 in the partition cover 9; two butted sealing plates 31 are elastically hinged at the bottom of each partition cover 9, and the sealing plates 31 are used to seal the nozzle in the partition cover 9 to prevent a small amount of paint liquid adhering to the nozzle from falling onto the flat iron after spraying, thereby affecting the spraying quality; the sealing plates 31 are provided on the bottom of each partition cover 9, and the sealing plates 31 are provided on the bottom of each partition cover 9, so as ... A groove is arranged on the inner wall of the partition cover 9 where 1 is located. In the initial state, the sealing plate 31 is in a horizontal state and abuts against the top of the groove; a driving member is hinged on the side wall of each sealing plate 31, and the driving member is movably connected with the partition plate 32 arranged on the side wall of the partition cover 9, wherein the partition plate 32 is arranged on one side of the opening of the accommodating groove 10 along a vertical sliding manner; during operation, as the partition cover 9 moves downward, the sealing plate 31 contacts the push plate 30, and as the partition cover 9 continues to move downward, the push plate 30 pushes the sealing plate 31 away along the hinge point, and the nozzle is exposed; in order to reduce the push plate In order to prevent the wear between the plate 30 and the sealing plate 31, the present invention preferably provides a roller 33 on the outer side of the push plate 30, and the top of the roller 33 is higher than the top of the push plate 30, so as to ensure that when the sealing plate 31 needs to be opened, the roller 33 first contacts the sealing plate 31, and the rotation of the roller 33 is used to reduce the wear between it and the sealing plate 31; at this time, due to the limit plate 25, the receiving groove 10 of the partition cover 9 will not contact the flat iron, and there is a gap between the partition cover 9 and the flat iron, and the paint may escape to the front and rear sides during the painting operation. The position of the color paint is at it; therefore, through the setting of the driving member, as the sealing plate 31 is flipped, the driving member will be pushed to drive the partition plate 32 to move, so that the partition plate 32 will slide out and abut against the flat iron, so as to limit the paint spraying position within the specified space. At this time, the nozzle can be controlled to open for paint spraying operation; since the sealing plate 31 is hinged to the inner wall of the partition cover 9 by a torsion spring, after the painting is completed, as the partition cover 9 and the push plate 30 are gradually separated, while the torsion spring drives the sealing plate 31 to reset, it will drive the driving member to reset the partition plate 32.

[0024] Specifically, the driving member includes a connecting rod 34 hinged on one side of the sealing plate 31, and the connecting rod 34 is movably connected to a push rod 35. An accommodating chamber 36 is provided at one end of the push rod 35 connected to the connecting rod 34, and the connecting rod 34 is elastically slidably located in the accommodating chamber 36. The sliding connection between the connecting rod 34 and the push rod 35 can avoid being restricted when the sealing plate 31 is rotated and opened along the intersection; the push rod 35 is hinged on the side wall of the partition cover 9; an arc-shaped guide groove 37 is opened through the side wall of the partition cover 9, and a push shaft 38 slidingly located in the guide groove 37 is provided at one end of the push rod 35 away from the connecting rod 34. A slide groove 39 is horizontally opened at the bottom of the partition plate 32, and the push shaft 38 extends from the guide groove 37 and is movably located in the slide groove 39. The sealing plate 31 rotates along the hinge point, driving the connecting rod 34 to push the push rod 35 to rotate along the hinge point, and the push shaft 38 at the end of the push rod 35 moves upward along the opening direction of the guide groove 37 to realize the ejection of the partition plate 32. In this embodiment, the partition plate 32 is arranged on the outside of the partition cover 9, and the partition plates 32 on both sides are driven by the two sealing plates 31 through the driving members, and the two driving members are respectively arranged at the two ends of the partition cover 9; the side wall of the partition cover 9 is provided with a dovetail groove 40, and the partition plate 32 is provided with a sliding block 41 matched therewith, so as to guide the partition plate 32 to move up and down.

[0025] Furthermore, the contacting surfaces of the two sealing plates 31 are inclined slopes, which are convenient for opening and closing. The two sealing plates 31 are provided with receiving grooves 42 on one side close to the nozzles. The receiving grooves 42 are located below the nozzles. Adsorption blocks 43 are provided in the receiving grooves 42. Adsorption blocks 43 are used to absorb the liquid paint dripping from the nozzles, so as to prevent the liquid paint dripping on the sealing plates 31 from being in a flowing state and falling onto the flat iron below during each opening of the sealing cover 12, thereby enhancing the practical performance of the present invention. Among them, the adsorption blocks 43 can use porous materials similar to sponges to achieve adhesion to a small amount of dripping paint, so that it is not easy to fall off.

[0026] When the present invention is in use, firstly, the distance between the two limit plates 25 is adjusted, the flat iron is placed in the space between the two limit plates 25, and then the roller conveyor 1 is turned on. When the sensor detects that the flat iron runs to the bottom of the first paint spraying assembly, the control cylinder 18 is turned on to push the mounting plate 6 down, and the sealing plate 31 in the partition cover 9 first contacts the roller 33 on the push plate 30 until the sealing plate 31 is pushed open. At this time, the partition plates 32 on both sides are synchronously pushed out to abut against both sides of the length direction of the flat iron, and a section of the position required for painting is sealed and limited. At this time, the control system controls the corresponding air pump to start, so that the nozzle starts the paint spraying operation; because the partition cover 9 applies pressure to the flat iron, the roller 18 is turned on to start the paint spraying operation. Slipping will occur at the bottom of the flat iron and the flat iron cannot be transported, so the normal painting operation can be guaranteed; after the painting is completed, the cylinder 18 is gradually reset, and the partition cover 9 contacts the flat iron for pressing and positioning. The flat iron will move to the next painting assembly. After the flat iron moves into place, the painting assembly of the previous station is reset, and the flat iron of the next process completes the pressing and positioning of the flat iron, and the painting operation of the remaining position of the flat iron is realized. After the painting is completed, the corresponding painting assembly moves up, and the previous painting assembly descends to paint the flat iron running below, and so on. The whole operation has a high degree of automation, and the spraying effect is uniform, which effectively reduces the manual operation of physical strength, energy and time consumption, and improves work efficiency. In addition, the sensor mentioned in the present invention can be set on the mounting plate 6 or at the corresponding position in the protective cover 2. The control system adopts a PLC programmable logic controller, and the start and stop of the sensor and the roller conveyor 1, the operation of the heating equipment and the operation of the threaded screw 19 are all controlled by it. Since it belongs to a common structure in the prior art, its specific connection method and working principle are not described here. For the convenience of operation, an operation panel is provided on the protective cover 2 for inputting various command data.
