[0020] The present invention will now be described in detail with reference to the accompanying drawings.

[0021] A surface powder coating equipment for the production of security doors, such as Figures 1 to 3 As shown, the workbench includes a worktable 1. A fixed frame 2 is fixedly installed on the upper end of the workbench 1. A slide groove 3 is opened at both the left and right ends of the fixed frame 2. A lead screw 4 is movably connected in the left slide groove 3. A first motor 5 is fixedly installed at the lower end of the lead screw 4. The first motor 5 is fixed to the bottom of the workbench 1. A slider 6 is threadedly connected to the outer surface of the lead screw 4. The slider 6 slides in the slide groove 3. A sliding frame 7 is fixedly installed at the front end of the slider 6. A powder container 8 is fixedly installed at the front end of the sliding frame 7. A spray gun 9 is fixedly installed at the outlet of the output pipe of the powder container 8. A rotating shaft 10 is movably connected in the middle of the upper end of the workbench 1. A second motor 11 is fixedly installed at the bottom of the rotating shaft 10. A turntable 12 is fixedly installed at the upper end of the rotating shaft 10.

[0022] like Figure 1 As shown, an electric cylinder 13 is fixedly installed on the upper end of the fixed frame 2. A bearing 14 is fixedly installed on the output shaft of the electric cylinder 13. A positioning pressure plate 15 is fixedly installed on the bottom of the bearing 14. Through the telescopic movement of the electric cylinder 13, the positioning pressure plate 15 can be moved up and down to fix the safety door placed on the turntable 12 and prevent it from shifting during the powder coating process.

[0023] like Figure 1 As shown, a baffle 16 is fixedly installed on the upper rear side of the workbench 1 to prevent powder coating from splashing behind the workbench 1 during the powder coating process and to keep the working environment clean.

[0024] A storage box 17 is placed on the left and right sides of the upper end of the workbench 1. The storage box 17 is located on the left and right sides of the rotating shaft 10 and below the rotating table 12. It is used to collect excess powder coating or waste for convenient subsequent processing.

[0025] A limiting rod 18 is fixedly installed inside the right side slide 3. The limiting rod 18 is movably inserted into the right side of the sliding frame 7 to limit the horizontal movement range of the sliding frame 7 and ensure the stability and accuracy of the spray gun 9 during the powder coating process.

[0026] Working Principle: Safety Door Placement and Positioning: The safety door to be powder coated is placed on the placement turntable 12 on the workbench 1. The surface of the placement turntable 12 is usually made of rubber, which increases the friction between the placement turntable 12 and the safety door, ensuring that the safety door remains stable during rotation. The electric cylinder 13 is electrically connected to an external power supply through an external control switch group. When the electric cylinder 13 is started, the output shaft of the electric cylinder 13 drives the bearing 14 and the positioning pressure plate 15 to move downward. The bottom surface of the positioning pressure plate 15 is designed with anti-slip texture. Through the downward pressure action, the positioning pressure plate 15 firmly presses the safety door onto the placement turntable 12. The placement turntable 12, together with the positioning pressure plate 15, prevents the safety door from moving or shifting during the powder coating process.

[0027] Powder coating operation: Start the first motor 5, which drives the lead screw 4 to rotate. The rotational motion of the lead screw 4 is converted into the linear motion of the slider 6. The slider 6 slides up and down along the slide groove 3. The slider 6 drives the sliding frame 7, powder container 8 and spray gun 9 to move up and down synchronously. The powder coating process mainly utilizes electrostatic spraying technology. The powder coating is stored in the powder container 8 and delivered to the spray gun 9 through the output pipe. The spray gun 9 uses the electrostatic principle to evenly spray the powder coating onto one side surface of the safety door. During the spraying process, the powder coating becomes electrostatically charged, while the metal products such as the safety door are grounded or have the opposite charge, thereby attracting the powder coating to adhere evenly to its surface.

[0028] Rotary powder coating: After one side of the safety door is powder coated, the second motor 11 is started, driving the rotating shaft 10 to rotate. The electric cylinder 13, the first motor 5, and the second motor 11 are all electrically connected to an external power supply through an external control switch group. The operator can conveniently control the start, stop, and rotation speed of each motor through the control switch group. The rotating shaft 10 drives the turntable 12 and the safety door to rotate 180 degrees, so that the other side of the safety door faces the spray gun. During the rotation, the positioning pressure plate 15 always maintains a tight press on the safety door to ensure that the safety door will not be displaced due to rotation. The output end of the electric cylinder 13 is fixed at... On the inner surface of the bearing 14, this design prevents the output shaft of the electric cylinder 13 from rotating, but the positioning plate 15 at the bottom of the bearing 14 can rotate synchronously with the safety door and remain stable during rotation. The surface of the turntable 12 and the ground where the positioning plate 15 is placed are provided with anti-slip material to increase the friction between them and the safety door, so that the safety door and the positioning plate 15 rotate synchronously. At the same time, it ensures that the positioning plate 15 always applies uniform pressure to the safety door, maintaining the stable positioning of the safety door. Repeat the powder coating operation to powder coat the other side of the safety door without having to flip and reposition the safety door, which greatly shortens the powder coating cycle.

[0029] Powder recycling: During the powder coating process, excess powder coating will fall naturally. The storage boxes 17 on both sides of the workbench 1 effectively collect this excess powder coating, which is convenient for subsequent recycling and reuse, reducing production costs and reducing resource waste.

[0030] Curing process: After the coating is applied, the security door is sent to an external heating curing oven for heating and curing. During the heating process, the powder coating melts, flows, and eventually cures into a strong coating, providing protection and decoration for the security door.

[0031] In summary, the second motor 11 drives the rotating shaft 10 to rotate, thereby causing the safety door placed on the turntable 12 to rotate. In addition, the positioning plate 15 always provides good downward positioning for the safety door during processing or rotation, which can easily adjust the position of the safety door without the need for manual flipping and repositioning, greatly improving the powder coating efficiency.

[0032] It is worth noting that the first motor 5 and the second motor 11 disclosed in the above embodiments are servo motors, specifically the Panasonic MINAS A6 series, and the electric cylinder 13 is specifically the Festo EGC series. The external control switch group and the external power supply control the operation of the first motor 5, the second motor 11, and the electric cylinder 13 adopt methods commonly used in the prior art.

[0033] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
