Description

Technical Field

[0001] The utility model relates to the technical field of thermal spraying, in particular to a powder feeding mechanism for thermal spraying equipment. Background Technique

[0002] Thermal spraying is a surface strengthening technology that uses a high-temperature heat source to melt materials and then spray them onto the surface of a workpiece to form a coating with specific functions. Thermal spraying is a metal surface processing method that atomizes and sprays the molten spraying material onto the part surface through a high-speed air flow to form a sprayed coating. The thermal spraying equipment transports and sprays the powder through a spray gun.

[0003] In the process of using the existing technology, although there are many benefits, there are still the following problems. It lacks a shielding and protection structure for the nozzle, resulting in foreign objects or dust in the outside world adhering to the nozzle when the spray gun is not in use, causing pollution to the nozzle, and the nozzle is prone to collide with external equipment, affecting the service life of the nozzle. Content of the Utility Model

[0004] The purpose of the utility model is to provide a powder feeding mechanism for thermal spraying equipment to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A powder feeding mechanism for thermal spraying equipment, including a fixing plate, a ferrule, an electric push rod and a protective cover. One end outer wall of the fixing plate is provided with a spray pipe. A limiting plate is installed on one side outer wall of the spray pipe. A ferrule is installed on one side outer wall of the spray pipe. An electric push rod is rotatably installed inside the ferrule. One end outer wall of the electric push rod is installed with a connecting rod. One side outer wall of the connecting rod is installed with a protective cover.

[0006] When using the powder feeding mechanism for thermal spraying equipment in this technical solution, the motor body drives the electric push rod to rotate in a circular motion until the protective cover moves to the outside of the nozzle. The electric push rod drives the protective cover to move horizontally until the nozzle enters the protective cover, and the sealing gasket contacts the limiting plate to ensure the sealing performance of the nozzle inside the protective cover.

[0007] Preferably, handle grips are provided on both outer walls of the fixing plate, and a handle is rotatably installed on one side outer wall of the fixing plate. Workers can hold the handle grips to pick up the fixing plate and the spray pipe, and can control the material to be ejected under control by controlling the handle.

[0008] Preferably, a nozzle is provided on one end outer wall of the spray pipe, and the nozzle is located inside the protective cover. The material inside the spray pipe is ejected through the nozzle under control.

[0009] Preferably, the limiting plate is designed in a disc shape, and the size of the limiting plate is adapted to the size of the protective cover. The limiting plate is connected to the protective cover to shield the nozzle.

[0010] Preferably, a motor body is provided on the outer wall of one end of the card sleeve through which the electric push rod passes, and the motor body is connected to the outer wall of the card sleeve. The motor body drives the electric push rod to rotate circumferentially to adjust the use position of the protective cover, enabling the protective cover to move away from the outside of the nozzle.

[0011] Preferably, one side outer wall of the protective cover is designed with an open mouth, and the protective cover is located outside the spray pipe. The protective cover can store and protect the nozzle.

[0012] Preferably, a sealing gasket is fixedly attached to one side outer wall of the protective cover, and the sealing gasket is in contact with the outer wall of the limiting plate. The sealing gasket ensures the sealing performance between the protective cover and the limiting plate.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: By setting the electric push rod, the protective cover and the sealing gasket, the present utility model achieves the effect of protecting the nozzle. The motor body drives the electric push rod to rotate circumferentially until the protective cover moves to the outside of the nozzle. The electric push rod drives the protective cover to move horizontally until the nozzle enters the interior of the protective cover, and the sealing gasket is in contact with the limiting plate, ensuring the sealing performance of the nozzle inside the protective cover, preventing the nozzle from coming into contact with external equipment or foreign objects when not in use, achieving the purpose of shielding and protecting the nozzle, and improving the service life of the nozzle.
