Embodiment Construction

[0046] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. The following descriptions of the specific implementations are only exemplary, and it should be understood that the specific implementations described here are only used to explain the present invention, but not to limit the present invention and its application or usage.

[0047] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. In ...

Abstract

The invention relates to a device and method for removing a coating on the surface of a spraying rack. The device is used for removing the coating on the surface of the spraying rack. According to thedevice, a high-pressure air pipe communicates with a shot containing box, one end of a shot conveying pipe communicates with a shot outlet of the shot containing box, and nozzles are arranged at theother end of the shot conveying pipe. The nozzles are fixed to the two opposite side walls of a shed and the spraying rack is arranged between the two opposite side walls of the shed. After high-pressure gas pushes shots in the shot containing box to pass through the shot conveying pipe, the shots are ejected out of the nozzles and jet to the coating on the surface of the spraying rack, and the shots impact on the surface on the surface of the spraying rack, so that the coating is separated from the spraying rack. The coating on the surface of the spraying rack can be effectively removed, spraying rack losses can be reduced, and meanwhile the period of removing the coating on the surface of the spraying rack is effectively shortened. The invention further provides a method for removing thecoating on the surface of the spraying rack.

Description

technical field [0001] The invention relates to the technical field of spraying, in particular to a device and method for removing the surface coating of a spraying rack. Background technique [0002] Spraying hanger refers to the tooling used to hang the workpiece during the spraying operation. In the current home appliance industry, the surface treatment process of sheet metal parts related to appearance is generally electrostatic spraying on the surface. Electrostatic spraying uses high-voltage electrostatic field force to negatively charge the powder, and is adsorbed to the surface of the workpiece under the action of electric field force. Finally, a relatively uniform and firm coating is obtained. During the electrostatic spraying process, the surface of the spraying hanger that hangs the workpiece will also form a coating. In the case of repeated use, the surface coating of the hanger will become thicker and thicker, which will affect the use of the spraying hanger. ...
