What is the working principle of the towel cloth setting machine?
The working principle of the towel cloth setting machine mainly includes the following steps:
1. Fabric feeding stage
The terry cloth enters the setting machine smoothly through the cloth feeding device. The cloth feeding device usually consists of a cloth guide roller and a tension adjustment device. The tension adjustment device can ensure that the terry cloth maintains appropriate tension when entering the setting machine to avoid being too loose or too tight and affecting subsequent processing.
2. Warm-up stage
Heating: After the towel cloth enters the preheating zone, it is heated by a heating device. The heating methods usually include steam heating, electric heating or hot oil heating. The heating device transfers heat to the towel cloth, causing its temperature to gradually increase.
Function: The purpose of preheating is to increase the plasticity of the terry cloth, so that its fibers can adjust their shape more easily during the subsequent stretching and shaping process. At the same time, preheating also helps to remove some of the moisture in the terry cloth, preparing for better shaping effects.
3. Stretching stage
Transverse stretching: In the stretching zone, the terry cloth is stretched transversely by mechanical or pneumatic devices. For example, the terry cloth is clamped on both sides by needle plates or cloth clips, and then the transverse stretching is achieved by adjusting the spacing between the needle plates or cloth clips. Transverse stretching can adjust the width of the terry cloth to the specified size.
Longitudinal stretching: At the same time, the terry cloth is stretched longitudinally by the speed difference of the cloth guide roller or other methods. Longitudinal stretching can adjust the length of the terry cloth and make it flatter.
4. High temperature setting stage
Heating and insulation: After being stretched, the towel cloth enters the high-temperature shaping area, which is equipped with efficient heating equipment and insulation devices to ensure that the temperature is evenly and stably maintained at the set shaping temperature.
Fiber structure adjustment: Under high temperature, the fiber structure of the terry cloth is rearranged and adjusted. The bonding force between the fibers is enhanced and the shape is fixed. The shaping time depends on the material and requirements of the terry cloth, generally ranging from tens of seconds to several minutes.
5. Cooling stage
Rapid cooling: After shaping, the towel cloth enters the cooling zone and is quickly cooled by the cooling device. The cooling methods usually include air cooling or water cooling. Rapid cooling can quickly fix the fiber structure in the new shape to ensure a long-lasting shaping effect.
Stable shape: After cooling, the towel cloth becomes more stable and is less likely to change in size and shape.
6. Fabric output stage
The cooled towel cloth is smoothly led out of the shaping machine through a cloth discharging device. The cloth discharging device may include a winding device, etc., to neatly collect the shaped towel cloth for subsequent processing or packaging.
In summary, the terry cloth setting machine achieves the required dimensional stability, softness and appearance of the terry cloth through a series of processes such as preheating, stretching, high-temperature setting and cooling.
When we touch the towels carefully processed by the shaping machine and feel their comfort and beauty, we can't help but be impressed by the charm of modern technology. The towel shaping machine is not just a piece of equipment, but also the creator and guardian of quality life.
