Description

Technical Field

[0001] The utility model relates to the technical field of guardrail processing, in particular to a device for powder spraying of metal guardrails. Background Art

[0002] Powder spraying utilizes the corona discharge phenomenon to adsorb powder coating onto the workpiece. The powder spraying process is that the powder spray gun is connected to the negative electrode and the workpiece is connected to the positive electrode. The powder coating is sent into the spray gun by the powder supply system with the help of compressed air. A high voltage electrostatic generator is applied to the front end of the spray gun. Due to corona discharge, dense electric charges are generated near it. When the powder is sprayed out from the gun nozzle, a circuit is formed to form charged coating particles, which are attracted to the workpiece with the opposite polarity due to the electrostatic force. The metal guardrail powder spraying device is a device used to apply powder coating to metal guardrails. Its main function is to spray powder coating on the surface of metal guardrails.

[0003] Referring to the existing patent publication number: CN216605711U, a metal guardrail powder spraying equipment includes a processing box, a supporting mechanism is fixedly installed at the bottom of the processing box, a powder spraying box is fixedly installed on the top of the processing box, a delivery pump is fixedly installed on one side of the powder spraying box, a spray gun is fixedly installed on the top of the inner cavity of the processing box, and a motor is fixedly installed on the bottom of the processing box. The motor is used to drive the placement table to rotate, and the placement table will drive the workpiece to rotate. During the rotation process, the workpiece and the powder are fully in contact, avoiding the uneven powder spraying of the metal guardrail powder spraying equipment, thereby improving the spraying effect of the metal guardrail powder spraying equipment.

[0004] However, in actual use, the existing spraying device has a fixed position of the spray gun when spraying powder on the guardrail in the above application document. Although it can drive the guardrail to rotate, the spray gun is difficult to move and the spraying direction is fixed, resulting in inadequate overall spraying of the guardrail, poor flexibility, and low condensation efficiency of the spray material after spraying.
