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

[0017] Example 1: Double-layer toilet paper forming device

[0018] Referring to Figure 1, this embodiment 1 is composed of a headbox 1, a transmission filter screen 2, and a wind dewatering box 3, 4. The transmission filter screen 2 consists of rollers 6, 7, 8, 9, 10 installed on a frame 5. , 11, 12, 13, 16 transmission connection, the headbox 1 connects the first layer of tubular wood pulp nozzle 14 and the second layer of tubular wood pulp nozzle 15, the bottom of the headbox is at an angle of 5-30 degrees to the horizontal , The transfer filter 2 is matched with the bottom of the headbox, the wind dewatering boxes 3, 4 are arranged at the lower end of the transfer filter 2 corresponding to the headbox 1; the first layer of pipe type wood pulp nozzle 14 connected with the headbox Arranged in the same direction as the inclination angle of the bottom of the headbox, the second layer of tubular wood pulp nozzles 15 connected to the headbox are arranged vertically, and the short fi...

Embodiment 2

[0019] Example 2: Double-layer toilet paper forming process

[0020] 1) The bottom of the box body of the headbox is arranged at an inclination angle of 5 to 30 degrees from the horizontal;

[0021] 2). The first layer of long-fiber wood pulp and the spraying accounted for 20% of the total amount of spraying on the transmission filter screen 2 through the rollers 6, 7, 8, 9, 10, 11, 12, 13, and 16. The total amount of the second layer of short-fiber wood pulp is 80%; the long-fiber wood pulp is all prepared with commercially available long-fiber commercial wood pulp and water, and the short-fiber wood pulp is all commercial short-fiber commercial wood pulp. It is prepared by adding water; during the spraying process, the second layer of short fiber wood pulp is filled on the first layer of long fiber wood pulp, and each other is filled;

[0022] 3) At the lower end of the transfer filter screen corresponding to the headbox, a total of two wind dewatering boxes of the first stage a...

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 multilayer toilet paper forming device and its process. Background technique [0002] The four major indicators that affect the quality of toilet paper are strength, softness, absorption and linting resistance; strength is the ability to maintain the physical integrity of the product and the ability to resist tearing, tearing and shredding under the conditions of use; softness is direct It is related to the dry tensile strength of the paper web, rubbing it against the consumer's skin, or the touch felt by the user when rubbing in the hand; absorbency is the product's ability to absorb liquid, especially the ability to absorb aqueous solutions or dispersions; Fuzziness refers to the ability of a fibrous product and its constituent paper webs to stick together when in use conditions, including wet conditions. [0003] Products made from long-fiber wood pulp generally have better strength and linting resistance, while products made f...
