Intelligent powder barrel used for laser cladding powder feeder

Abstract

The invention relates to an intelligent powder barrel used for a laser cladding powder feeder. The intelligent powder barrel comprises a powder barrel body, a powder barrel mounting head, a powder barrel base, a powder barrel cover, powder barrel supporting rods, a vent pipe, a powder feeding scraping disc cover plate, an ultrasonic level meter, sealing joints and a data analysis module. The powder barrel body is fastened between the powder barrel mounting head and the powder barrel base through the powder barrel supporting rods. The powder barrel cover is in screw joint to the powder barrel mounting head. The powder barrel base is mounted on the powder feeding scraping disc cover plate. The vent pipe is located in the powder barrel body, one end of the vent pipe is mounted on the powder barrel base and communicates with the powder barrel body and a powder feeding scraping disc, and the other end of the vent pipe stretches to the top of the powder barrel body. A mounting hole is formedin the powder barrel cover, and the ultrasonic level meter is located in the mounting hole and is fastened and sealed in the mounting hole of the powder barrel cover on the inner side and the outer side of the powder barrel cover through the two sealing joints. The data analysis module is connected with the ultrasonic level meter. According to the intelligent powder barrel, dynamic balance of theair pressure of the powder barrel body and the powder feeding scraping disc is achieved, and meanwhile real-time monitoring and precise alarm responding to the quantity of residual materials in the powder barrel body are achieved.

Description

technical field [0001] The invention belongs to the technical field of additive manufacturing equipment, and in particular relates to an intelligent powder cylinder used for a laser cladding powder feeder. Background technique [0002] Most of the existing laser cladding powder feeders use sealed powder cylinders, only one powder outlet is opened at the bottom, and there is no material monitoring device. When the powder cylinder is filled with metal powder, especially metal powder with a small particle diameter, the air pressure in the powder cylinder will decrease with the continuous consumption of metal powder, so that the powder cannot pass through the powder outlet smoothly and enter the powder delivery scraper. . At the same time, the operator needs to constantly observe the remaining material in the powder cylinder during use. When the operator observes that the remaining material is insufficient, the operator needs to manually suspend the equipment to add powder. Alt...

Problems solved by technology

[0003] In order to solve the technical problems in the known technology, the present invention provides an intelligent powder cylinder for laser cladding powder feeder. When the powder cylinder is in normal operation, it can realize the overall airtightness of the powder cylinder and the air pressure inside the powder cylinder. The automatic balance of the air pressure of the powder feeding scraper can achieve a more stable and efficient powder feeding effect; at the same time, the remaining materials in the powder cylinder can be detected, and the detection results can be sent to the data analysis module for analysis and conversion, and the materials in the powder cylinder can be obtained Surplus data, when the material surplus is too small, an alarm signal can be sent, so as to achieve the purpose of real-time intelligent monitoring of the material in the powder cylinder; it solves the problem of powder blockage caused by the unbalanced pressure of the powder cylinder of the existing powder feeder and the existing powder feeding The machine needs to manually monitor the material balance, and there are many uncertain factors
