High Speed Crescent Former Tissue Paper Machine

Crescent former tissue machine is an efficient equipment for producing household paper.

Its core advantages being fast dehydration, high-speed operation, and flexible product adaptability.
Working speed of crescent former tissue machine is usually 500-1600m/min, with daily output of 20-200 tons.

Technical Principles of crescent former tissue paper machine

1. Dehydration mechanism for crescent former
By using centrifugal force natural dehydration technology, the wet paper sheet is preliminarily dehydrated in the crescent former zone between the felt through the rotation of solid forming rollers, power consumption reduce about 20%.

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 cross-sectional quantitative deviation of less than 1.5%. Multi layer headbox design (such as double-layer dilution water system) can accurately control fiber layering.

Main Structure and Function of crescent former tissue machine
1. Component of crescent former tissue machine
4 roll cantilever design: including chest roll, separation roll, tension roll, and correction roll. When changing the screen, the operating side frame can be hydraulically opened to shorten maintenance time.
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, avoiding splashing that affects the uniformity of paper.
3. Drying section of crescent former tissue paper machine
Crescent former tissue machine use Yangke dryer, equipped with a built-in turbulence bar and siphon system, the steam utilization rate increase by 30%, and the steam consumption 1 ton paper reduce to less than 2.2 tons. 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
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 crescent former tissue paper machine.

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).

Crescent former tissue paper machine 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 pulp 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

High speed crescent paper machine usually use Yangke dryers

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. High speed crescent paper machines 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.
