[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this utility model can be combined with each other. The described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] Reference Figures 1 to 2 As shown, this utility model provides a welding wire powder feeding device, including a frame. From top to bottom, a hopper 1, a powder feeding cylinder 2, a powder guide, and a support for supporting the welding wire are arranged on the frame. The bottom end of the hopper 1 is connected to the powder feeding cylinder 2. The powder feeding cylinder 2 is horizontally arranged and a powder dispensing mechanism is provided inside the powder feeding cylinder 2. A drive device is provided on the frame. The powder dispensing mechanism and the drive device are driven together. A feeding port 7 is opened at the end of the powder feeding cylinder 2 away from the hopper 1. The feeding port 7 is correspondingly arranged with the powder guide.

[0020] The hopper 1 is used to store the powder and supply it to the powder feeding cylinder 2. The powder distribution mechanism can distribute the powder in the powder feeding cylinder 2 and drop it from the feeding port 7 into the powder guide and finally onto the welding wire, thereby realizing the addition of the powder to the welding wire.

[0021] Furthermore, the powder dispensing mechanism includes a rotating cylinder 3 coaxially rotatably connected inside the lower powder cylinder 2. The outer wall of the rotating cylinder 3 is provided with an arc-shaped groove 6 along the circumference. One end of the rotating cylinder 3 passes through one end of the lower powder cylinder 2 and is connected to a gear.

[0022] The drive device drives the rotating drum 3 to rotate, and the powder is carried to the lowest point of the rotating drum 3 through the arc groove 6. Under its own weight, the powder separates from the arc groove 6 and enters the powder guide through the feed port 7, thus achieving uniform powder feeding.

[0023] In this embodiment, a ratchet mechanism is provided at the end of the rotating drum 3 away from the gear. Specifically, the end of the rotating drum 3 is coaxially connected to the ratchet in the ratchet mechanism. This arrangement enables the rotating drum 3 to drive the ratchet to rotate, so that when the pawl enters the teeth, it strikes the ratchet, thereby causing the rotating drum 3 to vibrate and completely separate the powder from the arc-shaped groove 6, preventing the powder from sticking to the arc-shaped groove 6.

[0024] Furthermore, the powder guide includes a powder guide block 4, the top of which is provided with a V-shaped groove, which is corresponding to the discharge port 7, and the bottom of the powder guide block 4 is provided with a through hole.

[0025] The powdered flux, after being separated, falls into the powder guiding block 4, and under the action of the powder guiding block 4, the powdered flux passes through the through hole and lands precisely on the welding wire.

[0026] Furthermore, the support includes a wire support block 5, the top of which is provided with a receiving groove for the welding wire to pass through, and the receiving groove is correspondingly provided with a through hole.

[0027] The set receiving groove has a limiting effect on the welding wire, ensuring that the pulled welding wire is always directly below the through hole and that the surface of the welding wire is covered with flux powder.

[0028] Furthermore, to prevent the powder from sticking to the rotating drum 3, a vibration motor is installed on the outer wall of the lower powder drum 2.

[0029] Furthermore, the drive device is a geared motor, and the output shaft of the geared motor is connected to a drive gear, which meshes with the gear.

[0030] The working principle of the welding wire powder feeding device provided by this utility model is as follows: When in use, powder is added to the hopper 1, the welding wire is passed through the receiving groove on the wire support block 5, and the welding wire is slowly pulled by the welding wire traction device. The reduction motor is started, and the reduction speed drives the rotating drum 3 to rotate, and the powder in the lower powder cylinder 2 is distributed. The powder is added to the surface of the welding wire through the powder guide block 4. The hopper 1 continuously supplies powder to the lower powder cylinder 2, thereby realizing the operation of adding powder to the welding wire.

[0031] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
