[0039] 2. The coating equipment of the utility model moves the guide wire product up and down by moving the motor, which can better ensure the integrity of the guide wire product and improve the quality and efficiency. The guide wire coating can be increased to 1.7 meters in length, and the whole product can be increased to 3.5 meters. At the same time, the solution tube U-shaped moving mechanism is adopted, and the product installation also adopts the U-shaped guide tube 3 design, which increases the compatibility range, saves and reduces the appearance size of the equipment, and the equipment has a compact structure, fine details, simple operation and improves production efficiency.
