Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of decorative base paper humidification, more specifically, to a humidification device for improving the calendering effect of decorative base paper. BACKGROUND

[0002] In the manufacturing process of base paper for decorative paper, the calendering process can make the paper surface smooth and compact, so as to be suitable for printing decorative paper patterns and obtain aesthetic feeling, which is a very important processing procedure. The base paper calendering process is arranged after the drying section of the paper machine, that is, the paper is calendered before being wound on the paper machine. Generally, the moisture content of the base paper before calendering is more suitable at 6% to 8%, but after the drying section, the moisture content of the base paper is very low, and directly entering the calendering process can easily cause the paper to curl.

[0003] To solve the above problems, the application number 201921125927.2, the application name is a humidification device for improving the calendering effect of decorative base paper, which is recorded as follows: two humidification boxes are arranged opposite to each other and across the decorative base paper, a steam pipeline provides steam for the humidification boxes, and a drainage pipeline discharges condensed water in the humidification boxes. A certain distance is maintained between the two humidification boxes to form a passage for the decorative base paper. At least one row of steam injection holes is formed in each of the two humidification boxes. The steam injection holes are located on the box wall of the humidification box facing the decorative base paper. The steam injection holes are uniformly arranged along the width direction of the decorative base paper. The steam pipeline is connected to the front end of the humidification box, and the drainage pipeline is connected to the rear end of the humidification box. The front and back surfaces of the decorative base paper are humidified by the two humidification boxes, which improves the moisture content of the decorative base paper, avoids the curling of the paper during the calendering process, improves the calendering effect of the paper surface, and has a simple overall structure and is convenient to use.

[0004] Although the device has many benefits, it still has the following problems: the device has poor adjustability when humidifying the paper surface of base paper of various sizes. Once the paper is wide, it is difficult for the steam injection holes of the humidification box to uniformly humidify the paper, which can easily affect the humidification effect and has low applicability.

[0005] In addition, when humidifying base paper of various thicknesses, the steam injection acts on the surface of the base paper for humidification. However, because the steam is injected in the air, the excess steam tends to rise due to its light weight, which causes the steam to easily diffuse upwards, resulting in loss of steam. This not only affects the visibility of the surrounding environment, but also wastes the humidification water source, thereby increasing the humidification cost of the base paper and causing many inconveniences in actual use.

[0006] In view of this, we propose a humidification device for improving the calendering effect of decorative base paper. Utility model content
