BRIEF DESCRIPTION OF THE DRAWINGS
[0013] Figure 1 It is a structural schematic diagram of the utility model;
[0014] Figure 2 yes Figure 1 A partial enlarged view of part A. DETAILED DESCRIPTION
[0015] Combine the following Figure 1~Figure 2 The technical solution of the utility model is further illustrated by specific embodiments.
[0016] like Figure 1 The plate width adaptive spraying device shown includes: a conveying frame 1, a gantry 13, a distance sensor 2, a controller 9, a liquid distribution pipe 10, a piston 5 and a nozzle 4. The gantry 13 is arranged on the conveying frame 1, and a conveyor belt or roller 12 is arranged on the conveying frame to convey the plate 11 so that the plate 11 passes under the gantry 13.
[0017] The liquid distribution pipe 10 is horizontally arranged in the gantry 13 and located above the conveying frame 1, and the nozzles 4 are arranged at intervals at the bottom of the liquid distribution pipe 10. Figure 2 As shown, the coating is sprayed on the top surface of the plate 11 using the spray head 4. A large number of spray heads 4 can meet the spraying requirements of large width plates. When spraying small width plates, it is necessary to close the liquid supply of some spray heads.
[0018] A liquid pump 6 is arranged on the gantry 13, a pipeline 7 is arranged between the liquid outlet of the liquid pump 6 and the middle of the liquid distribution pipe 10, a liquid supply pipe is arranged at the liquid inlet of the liquid pump 6, and the liquid supply pipe is externally connected to a paint tank to extract paint, and send it into the liquid distribution pipe 10 through the pipeline 7 to supply the nozzle 4 for spraying.
[0019] In order to ensure the spraying effect, a certain pressure needs to be maintained in the liquid distribution pipe 10. A pressure sensor 8 is provided on the liquid distribution pipe 10. The pressure sensor 8 is connected to the controller 9 to send a pressure signal and monitor the pressure in real time. The controller 9 is connected to the liquid pump 6 to adjust the speed to ensure the pressure stability of the liquid distribution pipe 10.
[0020] like Figure 1 As shown, in this embodiment, the controller 9 is arranged on the gantry 13 to avoid extra space occupation and compact structure. The controller 9 can adopt PLC, with a touch screen, easy to operate, and conducive to improving the automation level of spraying.
[0021] Electric telescopic rods 3 extending into the liquid distribution pipe 10 are respectively arranged on both sides of the gantry 13. Figure 2 As shown, the piston 5 is arranged in the liquid distribution pipe and is connected one-to-one with the electric telescopic rod 3. The extension and retraction of the electric telescopic rod 3 drives the lateral movement of the piston 5, so that the nozzle at the edge can be closed or opened, thereby improving the adaptability to the width of the plate 11 and the deviation problem during transportation, which is beneficial to saving paint and avoiding the problem of local coating leakage on the plate.
[0022] The distance measuring sensors 2 are symmetrically arranged on both sides of the conveying frame 1, and the electric telescopic rod 3 and the distance measuring sensors 2 are respectively connected to the controller 9 to perform automatic telescopic control of the electric telescopic rod 3. Figure 1 As shown, the distance measuring sensor 2 is horizontally pointed to the side edge of the plate to monitor the distance between the two side edges of the plate 11 and the edge of the conveyor frame 1, so that the controller 9 can control the extension and retraction of the electric telescopic rod 3, adjust the position of the piston 5, and close or open the liquid supply to the nozzle of the edge part.
