Laser Machines Introduced For Textile Machinery

< p > > a href= "//www.sjfzxm.com/news/" > cloth > /a > cutting generally uses high-speed damage machine CM or TM series, generally choose 50mm focusing lens, single layer cutting normal speed is 5 m / min, light intensity is 40%, air pump power size, beehive plate quality and smoothness, light intensity will affect the cloth damage effect.

The greater the intensity, the greater the heat radiation, and the light will create gaps.

At present, the biggest problem of cutting is the phenomenon of yellowing, placing the cloth on the honeycomb floor, opening the exhaust fan, extracting the smoke and dust in time, preventing the smoke and dust produced when cutting, spreading the cloth into the Yellow air, opening the air compressor, ensuring the blowing of fruits, blowing the impurities and volatiles in the slotting, and blowing inert gas (such as nitrogen).

< p > (1), ordinary fabric cutting (non-woven, polyester, dacron, silk, satin, twill, etc.) cloth is light and thin material. In order to ensure the effect of incision, we usually use 50mm focusing lens, with fine spot and small slit.

Open the external equipment (ventilation and blowing) of the laser machine, and evenly distribute the cloth onto the honeycomb floor.

Speed: large graphic or graphic external curve smooth part can be used at a higher speed, taking CM as an example, generally in 3-10 meters / minute; small graphics or graphics inside the curve or corner part of the use of low speed, generally in 0.5-3 meters / points, light intensity: light intensity matching principle is high-speed high light intensity, low speed with small light intensity, general adjustment time is strong 30-60, low speed is 18-35%, and there is a difference between the size of light intensity, generally around 5-15%, in order to achieve straight line cutting and curve acceleration and deceleration when the size of light intensity matching.

< p > (2) special a href= "//www.sjfzxm.com" > cloth > /a > cutting (white cotton cloth, dust-free cloth, containing PC and plastic composition cloth, etc.) process requirements: white cotton cloth requires no yellow cutting, no color change after cutting, no incision is hard, for these two fabrics, we need to use 50mm focusing lens, preferably imported RF laser, to ensure the quality and stability of the spot.

Open air and blow (cut a href= "//www.sjfzxm.com/news/index_c.asp" > cotton > /a > air compressor), conditional recommend nitrogen.

Speed: 1.5-3 M / min, light intensity: 20-30%, because we want to achieve the purpose of not yellowing and hard cutting, we must use medium speed to match the appropriate light intensity to cut, too fast. We must improve the intensity of light, so that the incision will change or harden because of the scorching of high light and high temperature, and the speed is too slow.

As far as the current equipment and technology are concerned, it is difficult to achieve this process perfectly, especially the thicker white cotton surface. The incision will be discolouration, and the dust-free cloth will also appear slightly hard.

< p > double layer cloth (dry glue) cutting (upper layer cut and no damage or slight damage on the next layer). This is the processing technology of the electronics industry. It has higher requirements for the matching accuracy, stability and speed of light intensity of the laser. At present, we generally adopt the domestic glass tube proofing, basically achieve the effect, but for large batch processing, it is recommended to use imported RF laser.

Open the air to blow, blow the cloth evenly on the honeycomb, and adjust the evenness of the four corners of the honeycomb bottom plate.

Speed and intensity setting: the specific parameters depend on the material, and both can achieve a better match. Generally, the upper layer is about 1.5-6 meters, and the intensity is about 18-35. The next level of light intensity has no specific requirements. It can be as fast as possible when ensuring the quality of the better incision. In addition, there must be a difference when setting the light intensity, so as to ensure the depth of cutting is consistent in acceleration and deceleration.

< p > (some materials can not be inflatable) the cutting of fabric marks (cloth, weaving marks and trademarks) is mainly done by two modes of automatic photography and semi-automatic manual cutting. The accuracy depends mainly on the accuracy of the machine's debugging and positioning. There are some differences in each weaving Mark, and it is impossible to cut each edge completely.

The requirement for cutting is similar to that of ordinary cloth cutting. However, because of the accuracy and hardness of woven label, the trademark is much larger than cloth, and there is a big difference in light intensity and speed.

Speed and intensity depend on the specific parts. The reference parameters are speed 1.2-5 M / min and intensity 20-55%.
