Detailed Implementation

[0018] The following will describe in detail the implementation of this utility model with reference to the accompanying drawings and embodiments, so that the implementation of this utility model can be fully understood and carried out based on how technical means are used to solve technical problems and achieve technical effects.

[0019] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of a rapid coating production line according to an embodiment of the present invention; Figure 2 This is a schematic diagram of the spraying chamber in an embodiment of the present invention.

[0020] As shown in the figure, a rapid coating production line includes: a spraying chamber 10, which has an inlet 11 and an outlet on the left and right sides, respectively, for conveying a conveyor chain 20. The conveyor chain 20 is equipped with a positioning plate 30 for fixing workpieces. The positioning plate 30 has a positioning gear 31 fixed on its lower side and a positioning rod 32 installed on its upper side. A spraying window 33 is provided on the front side of the spraying chamber 10. A screw bracket 40 is installed on the front side of the spraying chamber 10. The screw of the screw bracket 40 is driven by a motor via a belt. A lifting seat 41 is installed on the screw via a slider. A coating spray gun 50 is installed on the lifting seat 41 and extends into the spraying window 33. A pressing cylinder 60 is installed on the upper side of the spraying chamber 10. The pressing cylinder 60 drives a pressing plate 61 located inside the spraying chamber 10 to rise and fall. The pressing plate 61 has a through hole corresponding to the positioning rod 32. A drying chamber 70 is located behind the outlet of the spraying chamber 10.

[0021] In one embodiment of this utility model, the spraying chamber 10 is a steel rectangular cavity, 3 meters long, 1.5 meters wide, and 2 meters high. A feed inlet 11, 0.5 meters wide and 0.8 meters high, is provided on the left and right sides. The conveyor chain 20 is a plate chain that passes through the feed inlet 11 and the feed outlet 10.

[0022] A positioning plate 30 with a diameter of 300mm is installed every 0.6 meters on the conveyor chain 20. The positioning plate 30 has a positioning gear 31 fixed to its lower surface by bolts, and a positioning rod 32 welded to its upper surface for mounting the workpiece to be sprayed.

[0023] A 400×200mm spraying window 33 is opened in the middle of the front side of the spraying chamber 10, and a screw bracket 40 is fixed to the outside by bolts. A motor is installed on the side of the screw bracket 40. The motor drives the screw to rotate through a belt, so that the slider that is matched with the screw rises and falls. The slider is fixed to the lifting seat 41. The painting spray gun 50 is fixed on the lifting seat 41 by a buckle. The spray gun nozzle extends into the interior of the spraying chamber 10.

[0024] A pressure cylinder 60 with a diameter of 80mm is installed on the top of the spraying chamber 10. The piston rod end is connected to a pressure plate 61 made of 20mm thick steel plate. The pressure plate 61 has a through hole 18, which corresponds to the position of the positioning rod 32, and can press the workpiece down to the positioning plate 30.

[0025] The bottom of the spraying chamber 10 is equipped with a closed drive chain 80. Sleeves 81 are installed at both ends of the drive chain 80, and a drive gear 82 is installed at the front. Driven by a three-phase asynchronous motor, the drive chain 80 is supported and engaged with a positioning gear 31 via a U-shaped baffle 83 at the rear, thus driving the conveyor chain 20 for transmission. The drive chain 80 is supported at the rear by the U-shaped baffle 83, the surface of which is covered with a 5mm thick PTFE wear-resistant pad. This baffle also engages with the positioning gear 31 for transmission, allowing the conveyor chain 20 to move forward stage by stage. The three-phase asynchronous motor can be frequently started and stopped, making control convenient.

[0026] The upper rear side of the spraying chamber 10 is connected to an exhaust pipe 90 with a diameter of 150mm, which leads to the activated carbon waste gas treatment device.

[0027] The discharge port is connected to a 4-meter-long drying chamber 70, which uses hot air drying or is equipped with 3 sets of 2kW electric heating tubes and 2 axial flow fans. The working temperature range is adjustable from 50-120℃.

[0028] Working process: The workpiece is fitted onto the positioning rod 32 through the positioning hole. The conveyor chain 20, driven by the meshing of the drive chain 80 and the positioning gear 31, sends the workpiece into the spraying chamber 10. When the workpiece reaches the spraying position, the lowering cylinder 60 drives the lowering plate 61 to descend and press the workpiece. The motor drives the screw to rotate, which in turn moves the coating spray gun 50 up and down to complete the spraying. After the spraying is completed, the lowering plate 61 rises, and the workpiece is conveyed to the drying chamber 70 for hot air drying. Finally, the workpiece is unloaded from the end of the drying chamber 70.

[0029] The foregoing description illustrates and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or techniques or knowledge in related fields.
