Problems solved by technology

[0003] Products made from long-fiber wood pulp generally have better strength and lint resistance, while products made from short-fiber wood pulp have poorer lint resistance.
[0004] At present, the process disclosed abroad has better overall performance in terms of strength, softness, absorbency and lint resistance. The molding process and equipment are relatively complicated, and various chemical agents and resin activation components must be added.

Embodiment 1

[0018] Example 1: Double-layer toilet paper forming device

[0019] refer to figure 1 , the present embodiment 1 is made up of headbox 1, transfer filter screen 2, wind power dehydration box 3,4, and transfer filter screen 2 is made up of roller 6,7,8,9,10,11, 12, 13, 16 transmission connections, the headbox 1 is connected to the first layer of wood pulp nozzles 14 and the second layer of wood pulp nozzles 15, the bottom of the headbox is at an inclination angle of 5 to 30 degrees from the horizontal, and the transfer filter screen 2 and the headbox The bottom is matched, and the air dewatering boxes 3 and 4 are arranged on the lower end of the transfer screen 2 corresponding to the headbox 1. The first layer of wood pulp nozzles 14 connected to the headbox are arranged upwards in the same direction as the bottom of the headbox, and the second layer of wood pulp nozzles 15 connected to the headbox are arranged vertically downward.

Embodiment 2

[0020] Embodiment 2: double-layer toilet paper molding process

[0021] 1) The bottom of the headbox is arranged at an inclination angle of 5 to 30 degrees;

[0022] 2) On the transmission screen with an inclination angle of 5 to 30 degrees brought by the drive roller, spray the first layer of long-fiber wood pulp that accounts for 20% of the total amount and the second layer of short-fiber wood pulp that accounts for 80% of the total amount. Wood pulp; long-fiber wood pulp is all prepared by adding water to commercially available long-fiber commercial wood pulp, and all short-fiber wood pulp is prepared by adding water to commercially available short-fiber commercial wood pulp; during the spraying process, the second A layer of short-fiber wood pulp is applied on the first layer of long-fiber wood pulp and filled with each other;

[0023] 3) At the lower end of the transfer screen corresponding to the headbox, two air dehydration boxes, the first stage and the second stage, ...

Abstract

This invention refres to a kind of many layers bumf molding craftwork and setting which is made up of head box, passing filtering net, wind power dehydration box. The passing filtering net is connected by roller transmission that set on the frame. The head box connect with the nozzle, spray the first layer long fiber wood pulp which occupy 10~30% part of gross and the second layer short fiber wood pulp which occupy 70~90% part of gross, wind power dehydration, the bottom of head box form 5~30 degree obliquity with level. The passing filtering net match with the bottom of head box, the wind power dehydration set under the bottom of head box which is corresponding with the passing filtering net. The excellences are simple configuration, simple craftwork, processing conveniency, environmental protection, low investment and the operator is easy to foster.

Description

technical field [0001] The invention relates to a multi-layer toilet paper forming process and a device thereof. Background technique [0002] The four major indicators that affect the quality of toilet paper are strength, softness, absorbency and lint resistance; strength is the ability to maintain the physical integrity of the product and resist tearing, breaking and shredding under the conditions of use; softness is the direct Related to the dry tensile strength of the paper web, rubbing it against the skin of the consumer, or the tactile sensation felt by the user rubbing it in the hands; Absorbency is the ability of the product to absorb the amount of liquid, especially an aqueous solution or dispersion; Linting refers to the ability of a fibrous product and its constituent webs to bond together under conditions of use, including wet. [0003] Products made from long-fiber wood pulp generally have better strength and lint resistance, while products made from short-fibe...
