A welding wire feeding device with a base, fixing seat, conveying mechanism, and gas supply system that allows direct coupling to a working machine, adjustable conveying tube length, and inert gas protection, featuring a motor-driven wheel system and gas cylinder integration to prevent oxidation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional wire feeding devices are used, then wire conveyance function is provided, but the device cannot be directly installed to a nozzle and the conveying tube length cannot be adjusted
Solution Approach 1:
The wire feeding device is designed with a universal structure that can be directly installed to different types of nozzles, and the conveying tube length is made adjustable to adapt to various working distances and applications, making the device versatile for multiple welding and metal printing scenarios
2Reliability
If conventional wire feeding devices are used, then wire conveyance is provided, but protective gas cannot be supplied causing oxidation of molten metal
Solution Approach 1:
The gas supply system is integrated with the wire feeding device structure, combining the wire conveyance function and protective gas supply into a single unified device, eliminating the need for separate gas supply equipment while ensuring reliable protection of molten metal from oxidation
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables stable and precise wire conveyance, prevents oxidation of molten metal, and facilitates easy assembly and use by allowing direct nozzle connection and adjustable tube length, enhancing the device's usability in various fields.
Implementation Method 1
The passage is connected with a gas cylinder, so that an inert gas can be outputted from the air hole to prevent a workpiece from being oxidized due to exposure to oxygen
Implementation Method 2
The driving wheel is located at a position in contact with the driven wheel... the driven wheel is located in the accommodation trough of the base

AI summary
A welding wire feeding device includes a base, a fixing post, a pressing member, a motor, and a conveying mechanism. The pressing member is pivotally connected with a driven wheel. A tension spring is provided between the fixing post and the pressing member. A shaft portion of the motor is pivotally connected with a driving wheel. The conveying mechanism is coupled to the base and has an air hole. The base is formed with a first passage and a second passage connected with a gas cylinder. The length of the conveying tube of the conveying mechanism can be adjusted by pressing. A wire is sandwiched between the driving wheel and the driven wheel through the tension spring. The motor drives the driving wheel to rotate the driven wheel so as to continuously convey the wire; meanwhile, the inert gas can be sent out through the second passage and the conveying mechanism to prevent a workpiece from being oxidized.
