Embodiment 1

[0023] like figure 1 As shown, the carbonless copy paper coating production device of the present invention includes a carbonless copy paper coating production line, and the carbonless copy paper coating production line is sequentially equipped with a headbox 1, a wire section 2, a pressing device 3, and a front drying Equipment 4, curtain coater 5, drying oven 16, post-drying equipment 10 and calendering coiling equipment 11.

[0024] It works as follows:

[0025] When coating paper (CB paper) paper, the slurry flowing out from the headbox 1 passes through the wire part 2 to form the initial paper, and then passes through the pre-drying equipment 4 to obtain semi-finished paper, and the semi-finished paper is coated with a curtain coater 5 The layer of CB paint is dried through the air flotation drying oven 6, and then dried through the post-drying equipment (drying cylinder) 10, and then rolled up by the calendering coiling equipment 11 to produce the upper paper (CB paper)...

Embodiment 2

[0027] like figure 2 As shown, the carbonless copy paper coating production device of the present utility model includes a carbonless copy paper coating production line, and the carbonless copy paper coating production line is successively equipped with a headbox 1, a wire section 2, a pressing device 3, a pre-drying Drying equipment 4, film transfer coating machine 5, drying box I 6, middle drying equipment 7, curtain coater 8, drying box II 9, post-drying equipment 10 and calendering coiling equipment 11.

[0028] It works as follows:

[0029] When producing medium paper (CFB paper), the slurry flowing out from the headbox 1 passes through the wire part 2 to form the initial paper, and then passes through the pre-drying equipment 4 to obtain semi-finished paper. The semi-finished paper first passes through the film transfer coating machine 5 to coat a A layer of CF paint is dried through the air flotation drying oven 6, and then dried through the middle drying equipment (d...

Abstract

The invention relates to a built-in multi-coating carbonless paper production process belonging to the technical field of paper-making coating. The process comprises the following steps: enabling pulp from a head box to pass through a wire section to form raw paper, baking the raw paper on a pre-baking apparatus to obtain semi-finished paper, coating the semi-finished paper with a layer of paint by a coating apparatus, drying in a drying box, then drying on a post-baking apparatus, and coiling in a calendering and coiling apparatus to complete the one-time production of carbonless paper. The invention can realize the built-in multiple coating of raw paper of the carbonless paper, i.e. upper paper (CF paper), intermediate paper (CFB paper) and lower paper (CF paper) can be produced by one-time coating on the paper-making machine in the process of the producing raw paper of the carbonless paper without carrying out off-machine coating, thereby effectively saving energy consumption and human power.

Description

technical field [0001] The invention belongs to the technical field of papermaking coating, in particular to an in-machine coating carbonless copy paper production device. Background technique [0002] Carbonless copy paper is a kind of pressure-sensitive paper, which is generally composed of upper paper (CB paper), middle paper (CFB paper), and lower paper (CF paper). In the production process, a layer of CB coating is coated on the surface of the upper paper (CB paper), that is, microcapsules, and CF coating is applied on the front of the middle paper (CFB paper). One layer of CB paint is microcapsules, and a layer of CF paint is coated on the front side of the lower paper (CF paper), which is also a color developer. When the paper is pressed, the microcapsules rupture and react with the color developer to develop color, thereby replacing the traditional copying method of sandwiching blue paper in the middle of the paper, and realizing multi-link copying. However, at pre...
