[0002] In the melt-blown spinning process, it is necessary to control the quality of the product by changing the distance between the melt-blown die head and the receiving web-forming equipment. Generally, the melt-blown die head is adjusted by lifting and lowering. At present, the lifting and lowering of the melt-blown die head is carried out by only the melt-blown die head through the screw nut mechanism while the melt-blown platform does not move.

[0003] In this way, the melt pipe connected to the meltblowing die head adopts a flexible pipe, and the connection method is a detachable movable connection. Its sealing performance is not well guaranteed, and the stability of the meltblowing die head cannot be guaranteed after adding a cold air system.

The requirements for the quality of the spinning process and the output fiber position of the meltblowing die head under different conditions are met; and the molten material pipeline originally connected to the meltblowing die head can be rigidly connected to solve the sealing problem and other line layout order problems. The pipelines and lines can be connected and arranged externally by the meltblowing platform after debugging, without internal adjustment, thereby improving the stability and safety of the equipment and reducing the complexity of the structure.
