Description

Technical Field

[0001] The utility model relates to the technical field of filter paper production equipment, in particular to a mass production equipment for nanofiber composite filter paper. Background Art

[0002] As a scientific tool, filter paper can effectively filter impurities. Depending on the type of fiber that makes up the filter paper, the performance and use of the filter paper are different. There are ordinary filter papers for general occasions, glass fiber filter papers for high temperatures, and polypropylene filter papers for ultra-clean use.

[0003] In the prior art, there is a mass production device for nanofiber composite filter paper (Announcement No.: CN210262501U), which is used to form a nanofiber membrane layer on a substrate, including an unwinding device, a winding device, a spinneret assembly 1 and a spinneret assembly 2; the spinneret assembly 1 includes a receiving screen 1 and a spinneret 1; the spinneret assembly 2 includes a receiving screen 2 and a spinneret 2; there is an electric field between the spinneret and the receiving screen; the spinneret is used for spinning, and the electrostatic spinning solution ejected is accelerated by the electric field to form a nanofiber membrane layer on the substrate. The mass production device for nanofiber composite filter paper involved in the utility model can form a nanofiber membrane layer on the surface of a substrate in continuous mass production. Two sets of spinnerets are used to form a nanofiber membrane layer on the surface of the substrate, and the pearl-shaped nanofibers contain an incompletely volatilized solvent. The solvent can ensure that the nanofiber layer is tightly combined with the ordinary filter paper layer, ensuring that the nanofiber layer is not dispersed or peeled off when high-pressure fuel passes through. Although the mass production equipment for nanofiber composite filter paper uses two sets of spinnerets, the pearl-shaped nanofibers in the nanofiber membrane layer formed on the surface of the substrate contain an incompletely volatilized solvent. The solvent can ensure that the nanofiber layer is tightly combined with the ordinary filter paper layer, ensuring that the nanofiber layer is not dispersed or peeled off when high-pressure fuel passes through.

[0004] However, in actual use, after spraying, the surface of the filter paper will be wet, which will easily cause wrinkles on the filter paper, thereby easily affecting the flatness of the filter paper during the rolling process. Utility Model Content

[0007] Preferably, the leveling mechanism includes a fixed frame installed on a mounting frame, a heating plate is installed at the bottom of the fixed frame, a heater is arranged inside the fixed frame, three sorting rollers are arranged at the bottom of the fixed frame, connecting plates are installed at both ends of the three sorting rollers, and the two connecting plates are threadedly connected to the fixed frame through adjusting screws.

[0013] Preferably, one side of the dust removal box is set as an opening, and a baffle is installed on one side of the dust removal box through bolts, and the baffle is adapted to the opening.

[0014] Compared with the prior art, the utility model has the following beneficial technical effects: the heater heats the heating plate, thereby heating and drying the filter plate, and the filter paper can be leveled under the joint action of the leveling roller. By adjusting the setting of the screw, the distance between the leveling roller and the heating plate can be adjusted, thereby adapting to filter papers of different thicknesses and improving the use range of the production equipment;
