Further, the first pipe 20 gradually shrinks from the end far away from the scribing hopper 10 toward the end close to the scribing hopper 10, that is, the pipe diameter of the first pipe 20 gradually becomes smaller. Thus, the space in the first duct 20 becomes smaller and smaller, and the extrusion force applied to the hot melt coating is increased in the process of extruding toward the scribing hopper 10, so that the block-shaped hot melt coating is gradually crushed, thereby improving the crushing effect. Wherein, the pipe diameter of first pipeline 20 diminishes gradually, and can only be that the inner wall pipe diameter of first pipeline 20 diminishes gradually, and the outer wall pipe diameter of first pipeline 20 does not change, also can be that the pipe diameters of the inner wall of first pipeline 20 and outer wall all diminish gradually, and skilled person in the art can design according to actual conditions.
