Description

Technical Field

[0001] The utility model relates to the technical field of paper drying, in particular to a drying device for papermaking. Background Art

[0002] Papermaking is an important invention of the working people in ancient China. It is divided into two forms: machine-made and hand-made. The machine-made process is carried out continuously on a papermaking machine. The pulp suitable for paper quality is diluted with water to a certain concentration, and initially dehydrated on the mesh of the papermaking machine to form wet paper sheets, which are then pressed and dehydrated, and then dried into paper. The hand-made process uses a frame with a bamboo curtain, polyester mesh or copper mesh to copy the fibers suspended in the water into wet paper sheets, which are pressed and dehydrated, and then dried or dried into paper. The biggest difference between the machine-made and hand-made paper is that since hand-made paper is made by manual beating, the fibers in the pulp are well preserved, while machine-made paper is made by machine beating, and the pulp fibers are broken, making the hand-made paper much better than the machine-made paper in toughness and tensile strength. The machine-made paper has a pulp-net speed difference that leads to uneven longitudinal and transverse distribution of fibers, while the hand-made paper does not have uneven longitudinal and transverse distribution of fibers, which is especially reflected in the Xuan paper used for calligraphy and painting. Paper is one of the indispensable items in human daily life, so the demand for paper is very huge. In the process of papermaking, the paper usually needs to be dried.

[0003] The existing patent discloses CN201922259543.6 a papermaking drying device, comprising a main body, a conveying plate passing through the main body and paper at the top of the conveying belt, the conveying belt is at the top of the conveying plate, the main body is internally rotatably connected with a first heating roller, a second heating roller, a third heating roller and a fourth heating roller, the conveying belt and the paper are between the second heating roller and the third heating roller, the top of the main body is bonded with a first connecting pipe, one side of the main body is welded with two fixing plates, the utility model uses a heating wire to increase the temperature inside the main body and dry the paper, the water vapor generated by the drying of the paper rises and enters the heating through hole of the fifth heating roller, the water vapor condenses, and heats the fifth heating roller, the fifth heating roller preliminarily dries the paper outside the main body that has not yet entered the main body, the water vapor energy evaporated from the paper is reused for paper drying, which not only saves energy but also improves the drying efficiency, but still has the following problems;

[0004] The drying method adopted in this patent document has a fixed position and angle of the heating wire. When drying papers of different thicknesses, the overall heat of the heating wire cannot be effectively utilized, resulting in poor overall drying effect of the paper. In view of this, in-depth research was conducted on the above-mentioned problem, which led to the present case. Utility Model Content
