Description

Technical Field

[0001] The utility model relates to the technical field of mask production, in particular to a conveying and winding machine for mask meltblown cloth. Background Technique

[0002] Meltblown cloth, also known as meltblown non-woven fabric, is a kind of non-woven fabric. Meltblown cloth mainly uses polypropylene as the main raw material, and has the characteristics of many pores, loose structure and good anti-crease ability. It is the most core material for making masks. The production and processing technology of meltblown cloth includes four processes: meltblown forming, high-voltage electret, slitting and winding. Among them, slitting and winding are generally completed by a meltblown cloth conveying and winding machine.

[0003] During the meltblown process, it is usually necessary to wind the meltblown web for subsequent processes. However, polypropylene fibers with relatively high heat are likely to adhere to the winding roller during the winding process. The fibers with heat have strong adhesiveness, resulting in difficult cleaning of the surface of the winding roller. Furthermore, the flatness of the surface of the winding roller is reduced, which easily causes uneven winding of the meltblown cloth. Content of the Utility Model

While the rolling net 8 rotates, the present utility model sucks the gas inside the rolling net 8 through the air suction component, thereby generating a negative pressure inside the rolling net 8, and then pressing and fixing the ultrafine fibers on the outer wall of the rolling net 8 through the negative pressure to form a meltblown cloth. After that, when the rolling net 8 rotates above the air blowing channel 16, external gas is blown into the air blowing channel 16 along the air inlet 17 through the air inlet component.
