Embodiment 1

[0040]Example 1: hot air penetrating toilet paper machine

[0041] Referring to Fig. 2, Fig. 3 and Fig. 4, the present embodiment 1 is composed of a forming device 1, a paper web transfer device 2, a drying device 3, a cooling feeding box 4, and a roll cylinder 5; a forming device 1, a paper web transfer device 2 , the drying device 3, the cooling and feeding box 4, and the roll cylinder 5 are installed on the frame 6;

[0042] Forming device 1 is made up of headbox 7, transmission inclined wire 8, wind power dehydration box 9, 10, and transmission inclined wire 8 is composed of rollers 11, 12, 13, 14, 15, 16, 49, 50 transmission connection, the headbox 7 is connected to the first layer of wood pulp nozzles 17 and the second layer of wood pulp nozzles 18, the bottom of the headbox is at an inclination angle of 5 to 30 degrees from the horizontal, the transmission inclined net 8 matches the bottom of the headbox, and wind dehydration Boxes 9 and 10 are arranged at the lower en...

Embodiment 2

[0046] Embodiment 2: the processing method of hot air penetration drying toilet paper

[0047] Referring to Figure 1, for the 1092 model with a TAD conveyor network width of 1360mm, the following procedures are included:

[0048] A. Paper web forming:

[0049] 1. On the transfer inclined net with an inclination angle of 10 degrees arranged at the bottom of the headbox, the first layer is sprayed with long-fiber wood pulp, accounting for 20% of the total. The long-fiber wood pulp is all made of commercially available long fibers Commercial wood pulp is prepared by adding water; the second layer is sprayed with short-fiber wood pulp, which accounts for 80% of the total amount, and the short-fiber wood pulp is all prepared by adding water to commercially available short-fiber commercial wood pulp;

[0050] 2. Synchronously with spraying two-layer wood pulp, the transfer inclined wire is driven forward by the roller, and the paper web is dehydrated by wind through the dehydration...

Abstract

The invention relates to a hot wind penetrating toilet paper support and its processing technology, comprising of the forming device on the support, paper moving device, drying device and paper-wrapper, has passing net with an angle of 5-30deg.C to the forming device, thepulp-flowing tank linking to the nozzle, the first long-fiber wood pulp of 10-30% of the spraying and the second shot-fiber wood pulp of 90-70%, pneumatic dehydration, paper wind changing, paper TAD transmitting movement, hot wind penetrating drying, without the TAD dryer and Yank dryer. It has simple structure, convenient procession, low cost and other advantages, suitable for hot wind penetrating drying procession of toilet paper.

Description

technical field [0001] The invention relates to a hot air penetration type toilet paper machine and a processing technology for hot air penetration drying toilet paper. Background technique [0002] Since the late 1960s, it has been more than 30 years since the production of toilet paper by hot air penetrating drying (TAD) technology. The production of toilet paper by TAD technology means that the hot air penetrates the toilet paper before the wet paper is dried by the Yankee dryer. The dehydration process is quite gentle without strong pressing, so the finished paper is more fluffy, softer, and better absorbent. Due to the higher absorbency and softness of TAD toilet paper, consumers have higher expectations for high-quality toilet paper and paper towel products. Expectations continue to grow. At present, TAD technology is developing rapidly and has entered a mature stage. TAD technology is the most practical process for producing toilet paper. However, during the period w...
