Powder feeder with adjustable friction force of powder disc

Abstract

The invention discloses a powder feeder with the adjustable friction force of a powder disc. A lifting mechanism is further arranged between a spring and a motor, the compression amount of the spring can be adjusted through adjustment and control of the lifting mechanism, the counteractive pressure is adjusted by changing the compression amount of the spring, and therefore, the purpose of controlling the friction force between a powder basin and a powder falling opening is achieved. Under the condition that the friction coefficient is increased, the friction force can be reduced by increasing the spring space and reducing the reaction pressure, meanwhile, meanwhile, the pressure of the powder falling opening can be considered, and the situation that the sealing effect cannot be achieved due to too small pressure is avoided; the pressure can be linearly adjusted, meanwhile, the spring does not need to be replaced, so that the debugging convenience in use is improved, the model selection of the spring under various conditions does not need to be considered, and the applicability is enhanced; and in actual use, the pressure can be adjusted to reduce the friction force, so that the shutdown fault of equipment caused by the stalling of the powder disc when the friction force is greater than the torque of a motor can be avoided.

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 disc. Background technique [0002] The function of the powder feeder is to accurately send 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 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 type powder feeder, rotary table type powder feeder, scraper type powder feeder, capillary type powder feeder, drum type powd...
