Technical Principles of Crescent Former Tissue Machine For Toilet Paper

1. Dehydration mechanism for crescent former tissue machine

By using centrifugal force natural dehydration technology, the wet paper sheet is preliminarily dehydrated in crescent former zone between felt through the rotation of solid forming rollers (usually with a radius of 750mm). Compared with traditional vacuum cylinder mold machine for toilet paper, it is no need to rely on vacuum pump systems, and power consumption is reduced by about 20%. The power consumption per ton of paper can be controlled within 20-350kWh. Some high-end models crescent former tissue machine can further improve dehydration efficiency 2% -4% by adding vacuum steering rollers.

2. Fiber distribution optimization

The hydraulic headbox of crescent former tissue machine is equipped with honeycomb turbulence generator, which disperses fiber flocs through high turbulence intensity (10-15kPa), combined with parabolic distributor, to achieve a cross-sectional quantitative deviation of less than 1.5%. Multi layer headbox design can accurately control fiber layering, placing long fibers on the felt side to enhance softness, and short fibers close to the dryer to enhance strength.

Main Structure and Function of Crescent Former Tissue Machine For Toilet Paper
1. Forming part of Crescent Former Tissue Machine
4 roll cantilever design: chest roll, separation roll, tension roll, and correction roll. When changing the screen, the operating side frame can be hydraulically opened.
2. Water connection system of Crescent Former Tissue Machine
The curved guide plate combined with water mist baffle effectively collects white water generated by high-speed dehydration.
3. Drying section of Machine For Toilet Paper
Crescent Former Tissue Machine use Yangke dryer, equipped with a built-in turbulence bar and siphon system, the steam utilization rate is increased by 30%. Energy saving breathing masks further reduce energy consumption by recovering waste heat from condensed water.
4. Transmission and control system of Crescent Former Tissue Machine For Toilet Paper
The vector frequency conversion sub transmission technology realizes three-level PLC control and supports a speed synchronization accuracy of 0.1% level. The hydraulic pressure system of vacuum roller is linked with the tension sensor to ensure high-speed operation stability of machine for toilet paper.

Headbox

1.Open type headbox:

open top and lower pulp level. Mainly used for low-speed paper machine (usually with a speed below 300m/min), such as producing corrugated paper, cultural paper,

2.Air cushion type headbox:

The top is closed, and compressed air is introduced to form an air cushion, stabilizing the slurry level and evenly transmitting pressure. Suitable for medium to high-speed paper machines (speed 300-1000m/min), capable of producing cultural paper, packaging paper, etc.

3.Hydraulic headbox:

without air cushion, relying entirely on hydraulic action to achieve uniform distribution of slurry flow, high turbulence intensity, and good homogenization effect. Specially designed for high-speed paper machines (with speeds exceeding 1000m/min), it is the core configuration of crescent shaped toilet paper machines and mesh paper machines, which can meet the high uniformity requirements of thin paper (such as toilet paper and tobacco flakes).

Headbox of Crescent Former Tissue Machine For Toilet Paper

Crescent Former Tissue Machine For Toilet Paper hydraulic headbox:

1. Rack and adjustment system:

used to support and adjust the overall position and posture of the headbox

2. Cone tube slurry distribution:

slurry inlet pipe is designed according to the theory of equal pressure in the transverse direction of the cone tube to ensure uniform distribution of the initial slurry in the transverse direction.

3. Turbulence generator:

Generate appropriate high-strength micro turbulence in slurry flow, effectively disperse fibers, prevent fiber precipitation and re flocculation, and improve strength and uniformity of paper.

4. Lip plate:

It plays a role in stabilizing the slurry flow and further homogenizing.

5. Adjustable upper lip plate:

It can be adjusted in front, back, up, and down, forming a lip area in conjunction with the lower lip plate, accurately controlling the outflow angle and speed of the slurry.

6. Whole width adjustment of worm gear:

used for fine adjustment of the lip plate to ensure the uniformity of the paper product's horizontal measurement

Drying cylinder of paper machine

1.In the papermaking process, the function of the dryer is to dry the moisture in the paper and decorate the surface of the paper. crescent former tissue machine usually use Yangke dryers

2.The main components of the drying cylinder include the roller shell, turbulence rod, siphon tube, end cover, manhole cover, bearings, shaft head, steam joint, etc.

3.Drying principle: The saturated steam introduced from the steam joint condenses inside the drying cylinder, releasing heat that causes the temperature of the drying cylinder to rise, thereby heating the paper running on the surface of the roller shell. Heat is transferred to the paper through the contact between the paper and the surface of the dryer.
