Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. The preferred embodiments of the present invention are shown in the drawings. The 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. It should be noted that the terms "first" and "second" in the present invention do not denote any particular quantity or order, but rather are used for distinguishing names.

Referring to fig. 1 to 2, in the present embodiment, a meltblown web receiving apparatus includes a collecting wire roll 1, a cold water tank 3, and a dewatering and drying unit 4. The collecting net roller 1 comprises a suction inner container 12 with an upper opening and a net barrel 11 rotatably sleeved outside the suction inner container 12, wherein a plurality of uniformly distributed meshes are formed on the roller surface of the net barrel 11, the suction inner container 12 is provided with a main suction port and auxiliary suction ports distributed on two sides of the main suction port, a pair of partition plates are fixed on the edges of the main suction port and the auxiliary suction ports, the top ends of the partition plates are in contact seal with the roller surface in the net barrel 11, and the peripheral spaces of the main suction port and the auxiliary suction ports in the internal space of the net barrel 11 are separated by the partition plates to avoid interference, so that the overlapped position of the main suction port and the net barrel 11 is used as a main suction area 21, and the overlapped position of the auxiliary suction port and the net barrel 11 is used as an auxiliary suction area 22 by the suction effect of the main suction port and the auxiliary suction ports. The suction force of the auxiliary suction port is greater than the suction force of the main suction port.

Further, the suction liner 12 is connected to an exhaust fan preset in the outside.

Furthermore, the preset melt-blown nozzles are located right above the main suction area 21, so that melt-blown fibers sprayed by the melt-blown nozzles are received by the main suction area 21 and uniformly spread on the roller surface of the mesh cylinder 11 to form a web, and then the web is sent out along with the roller surface of the mesh cylinder 11, and the large suction force of the auxiliary suction area 22 is utilized to suck the melt-blown fibers leaked by the melt-blown nozzles in the spraying process, thereby effectively reducing resource waste and environmental air pollution.
