Embodiment Construction
[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. Including a frame 9, a cooling water tank 6 is installed on the frame for cooling and shaping the optical fiber loose tube 3, the cooling water 7 in the water tank is immersed in the optical fiber loose tube in real time, and the water volume control unit is used to control the water volume of the water tank 6 , to ensure that the cooling water in the water tank can submerge the loose tube of the optical fiber in real time. A variable-diameter main traction pulley 1 and a variable-diameter splitting pulley 2 are correspondingly installed above the cooling water tank, and the variable-diameter main traction pulley and the variable-diameter splitting pulley are separated by a certain distance along the traction direction, that is, the horizontal direction. The variable-diameter main traction wheel is a driving wheel, which is used to pull the loose tube and...
