Description

Technical Field

[0001] This utility model belongs to the field of specialty paper production technology and relates to a flattening device for specialty paper production. Background Technology

[0002] In the production of specialty paper, due to its typically high basis weight, large thickness, and uneven internal shrinkage, it is prone to warping and deformation. Furthermore, specialty paper often requires surface coatings with functional coatings, such as heat-sensitive coatings, oil-resistant coatings, and embossed coatings. These processes introduce new internal stresses, and uneven shrinkage during drying exacerbates curling; therefore, flattening devices are necessary for this purpose. Utility Model Content

[0003] The purpose of this invention is to solve the above-mentioned problems and provide a flattening device for the production of specialty paper.

[0004] To achieve the above objectives, this utility model provides a flattening device for the production of specialty paper, including a first conveying roller and a second conveying roller, with multiple sets of flattening rollers provided between the first conveying roller and the second conveying roller, and a sorting device provided on both sides of the first conveying roller.

[0005] Furthermore, the sorting device includes a drive device and a lead screw connected to the drive device. The lead screw has a first threaded area and a second threaded area. The first threaded area and the second threaded area are respectively fitted with a first slider and a second slider. The first slider and the second slider are symmetrically provided with guide clamps.

[0006] Furthermore, the flattening roller is an electromagnetically heated roller.

[0007] The beneficial effects of this utility model are as follows: This utility model discloses a flattening device for the production of specialty paper. Through the aforementioned configuration, paper is conveyed from the first conveyor roller to the second conveyor roller. A sizing device is installed on both sides of the first conveyor roller. The drive screw of the drive device rotates, causing two guide clamps to move towards each other, thus limiting and sizing the paper and ensuring its flattening to the flattening roller. The flattening roller is an electromagnetically heated roller. Through heat pressing, the paper fibers are re-structured in a relaxed state, releasing the internal stress accumulated in previous processes and achieving the flattening process.
