Third, the structural composition:1. The hand-held electric scraper is composed of an electronic stepless regulator and a single-phase series motor and a scraping blade. It adopts a light and micro-drag switch and a carbon brush. It has the characteristics of fast painting speed, high efficiency, simple operation, simple installation and stable quality, low failure rate, high production efficiency and novel design. 2. The fixed electric squeegee consists of two parts: electric power components (single-phase and series-excited motor) and scraping knives and governors.Fourth, the operation method: 1. Insert the enamelled wire head to be painted into the center of the tool holder, the power start switch (handheld) or the foot speed governor (fixed type), and the motor rotate. 2. Move the enameled wire in the opposite direction of the axial direction until of the enameled wire, then the film can be scraped off. 3. Release the power button switch (handheld) or relax the governor (fixed). 4. Replace the work and repeat the above steps. V. Wire diameter adjustment and related matters:1. When the enameled wire is of different specifications, the adjustable speed potentiometer (handheld) or the adjustable speed governor (fixed type) can be adjusted. The wire diameter is small in the slow direction, and the wire diameter is adjusted in the fast direction. If the film is not peeled off, the rotation speed is increased until it is scraped. If the enameled wire is cut by a scraper during speed regulation, the speed should be reduced until it meets the requirements. According to the above method, the most suitable rotation speed is as the working speed of the corresponding wire diameter, which can be considered to have been adjusted. 2. When scraping the paint to of the enameled wire, do not immediately disengage the three . The intersection of the should wait for the tool to stop rot and then disengage, so as not to rotate, the ename
