A powder feeder with adjustable friction force of powder disc

Abstract

The invention provides a powder feeder with adjustable friction force of the powder plate. By setting a lifting mechanism between the spring and the motor, the adjustment and control of the lifting mechanism realizes that the compression amount of the spring can be adjusted, and the compression amount of the spring can be adjusted. Reactive pressure, so as to achieve the purpose of controlling the friction between the powder basin and the powder outlet. When the friction coefficient becomes larger, the friction force can be reduced by increasing the spring space and reducing the reaction pressure. At the same time, the pressure of the powder outlet can be taken into account to avoid the pressure being too small to achieve the sealing effect; and because the pressure can be adjusted linearly , at the same time, there is no need to replace the spring, which improves the convenience of debugging during use, and does not need to consider the consideration of spring selection under various conditions, which enhances the applicability; in actual use, because the pressure can be adjusted to reduce friction, It can also prevent the powder pan from stalling when the friction force is greater than the motor torque, resulting in equipment downtime.

Description

technical field [0001] The invention relates to the technical field of powder feeders, in particular to a powder feeder with adjustable friction force of a powder pan. Background technique [0002] The function of the powder feeder is to accurately deliver the cladding powder to the laser melting machine according to the requirements of the processing technology, and to ensure that the powder can be conveyed continuously, uniformly and stably during the processing. The performance of the powder feeder will directly affect the quality of the laser cladding layer. With the development of laser cladding technology, higher requirements are also put forward for the performance of the powder feeder. According to different types of process characteristics and powder types, the types of powder feeders that have been developed at home and abroad mainly include screw powder feeders, turntable powder feeders, scraper powder feeders, capillary powder feeders, and drum wheel feeders. p...
