Embodiment

[0064] Example data: the minimum diameter of the Laval nozzle of the vacuum adsorption device is 1.5mm, and the inlet and outlet diameters are 5.0mm and 2.7mm respectively. When the air supply pressure is 0.5MPa, the vacuum degree reaches 90%.

[0065] Figure 7 It is a schematic diagram of the powder feeding system in an embodiment of the present invention.

[0066] Such as Figure 7 As shown, the powder feeding system consists of three parts: powder feeder, vacuum adsorption device and gas path. The argon gas is stored in the argon cylinder 2901 after being produced. After the machine is powered on, the electromagnetic gas valve 2902 is connected, and the argon gas flows out and is connected with the tee 2903, and flows through the regulating valve 2904 and the glass rotameter 2905. The regulating valve 2904 and the glass rotameter 2905 are used to regulate and stabilize the pressure and flow of the delivered gas. Adjust the gas pressure and flow according to different n...

Abstract

The invention provides a visual carrier gas type roller powder feeder and a powder feeding system. The system comprises the powder feeder, a vacuum absorption device and a spray welding gun which are arranged from top to bottom; the powder feeder is provided with a powder storage cylinder, a hopper base and a roller feeding device from top to bottom; through the transparent visual structure of the powder storage cylinder, the powder feeding condition can be intuitively perceived, and the non-stop material adding function is achieved; a glass cylinder is arranged in the hopper base, the visualization function in the powder conveying flowing process can be additionally achieved, during machine debugging, observation and control over adjustment of the powder feeding amount can be facilitated, and stability observation and anti-blockage observation of the powder feeding amount during normal work are achieved; and the vacuum absorption device can effectively avoid alloy powder bonding, conveying pipeline blockage, unsmooth powder feeding and the like, and the continuous, uniform and stable powder feeding needs are achieved. The feeder is particularly suitable for the work environment where a horizontal long arm spray welding gun does work and stretches into a machining workpiece, and consequently observation cannot be conveniently achieved; and the work air pressure ranges from 0.1 Mpa to 0.5 Mpa.

Description

technical field [0001] The invention relates to the fields of thermal spraying, plasma cladding and 3D printing, and specifically relates to a visual carrier-type roller powder feeder and a powder feeding system. Background technique [0002] The powder feeder is an indispensable device for storing alloy powder and delivering metal powder to the spray gun according to the corresponding process requirements in thermal spraying or spray welding equipment. According to different powder feeding methods, the existing powder feeding devices are mainly divided into screw type, scraper type, drum type and other structural forms. Different thermal spraying or spray welding processes have different requirements on the powder feeder, but whether the powder can be delivered accurately, stably, and evenly is the standard for inspecting the performance of various powder feeders. The quality of the sprayed or welded layer plays a very important role. [0003] Commonly used plasma spray w...
