Detailed Description

To facilitate an understanding of the utility model, the utility model is described more fully below with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided so that this disclosure will be thorough and complete.

Referring to fig. 1 or fig. 2, in this embodiment, a web forming device for meltblown fabric includes a motor 4, an inner roller 1, a mesh-shaped web roller 2, a roller frame 3, and a lifting driving mechanism, wherein a plurality of air suction openings 11 for ventilation are preset in the inner roller 1 along the circumferential surface of the inner roller 1 in an array arrangement. The mesh roller 2 is sleeved on the circumferential surface of the inner roller 1, wherein the mesh roller 2 and the inner roller 1 are mutually attached. The mesh roller 2 is formed by weaving stainless steel wires, and the meshes 21 of the mesh roller 2 are smaller than the air suction openings 11, specifically, the meshes 21 of the mesh roller 2 are oblique squares of 5mm by 5mm, so that the density of the meshes 21 of the mesh roller 2 is high. Two sides of the roller frame 3 are respectively provided with a mounting hole, and two ends of the inner roller 1 are respectively hinged with two ends of the roller frame 3. Motor 4 fixed mounting is in one side of barrel holder 3, and wherein, the output of motor 4 is connected with the one end of interior roller 1, and it is rotatory to drive interior roller 1 through motor 4, and wherein for interior roller 1 drives the net roller 2 and makes and interior roller 1 synchronous revolution. In this embodiment, when the web forming device is used, the fibers formed by the melt stream are agglomerated onto the cylinder of the mesh roll 2, and the mesh roll 2 is rotated to wind the fibers onto the mesh roll 2 to form a web; in the process, the net roller 2 with the high density of the grids 21 plays a supporting role for the fiber net, wherein the grids 21 of the smaller net roller 2 enable the fibers not to be blocked in one grid when the fiber net is formed, so that the cloth surface lines of the formed fiber net are shallower and less obvious.
