For a long period of time, plastic bags have brought great convenience to our daily life, but the ecological and environmental problems caused by plastic bags cannot be ignored. Its low recycling value has become the well-known "white pollution" , in my country, it has successively announced the implementation of the "plastic restriction order" to restrict the application of plastic bags. Non-woven bags have long been widely used in western developed countries, and energy-saving non-woven bags also have a tendency to replace polluting plastic bags in China. "Since then, it has been relatively rare for citizens to use a large number of plastic bags to carry things home in shopping malls, and environmentally friendly shopping bags of different materials have gradually become the new favorite of modern citizens.
So what equipment is needed for the manufacture of non-woven bags, and what is the process? Here, Wanshu Xiaoban will give you a brief explanation. At present, the manufacture of non-woven bags is usually based on the principle of ultrasonic waves. According to different functions, it is divided into Manual non-woven bag making machine and automatic non-woven bag making machine, usually a manual production line needs to add the following equipment: non-woven bag making machine, non-woven cutting machine, punching machine, Wrist strap welding machine, the following takes Wanshu automatic non-woven bag making machine as an example to introduce its production process:
1. Basic production process
The basic production process of the fully automatic non-woven bag making machine is feeding (non-woven roll material) → folding → ultrasonic bonding → cutting → bag making (punching) → waste recycling → counting → stacking. The process can be fully automated in time and only needs 1~2 people to complete the actual operation, and the manufacturing speed and equipment size can be adjusted within a certain range. The touch screen is used for actual operation, with step-by-step fixed-length, photoelectric tracking, automatic counting (can be set In order to further realize the actual effect of energy saving and environmental protection, colleagues have the function of recycling residual materials in the production process, and automatically collect the residual waste of bag making in the production process, which is conducive to the second use. Reduce labor intensity and improve work efficiency.
Features of automatic non-woven bag making machine
The design technology is advanced, the manufacturing speed is fast, the efficiency is high, it can process environmentally friendly non-woven bags of different specifications and shapes, and has the characteristics of good quality and adhesion strength.
1. Non-woven bag edge pressing: press the edge of non-woven bag;
2. Non-woven bag embossing: the pattern on the upper end and edge of the non-woven bag is pressed together;
3. Non-woven handle belt pressing: Automatically press the handle bag through the sleeve.
Equipment advantages:
1. The use of ultrasonic welding eliminates the need for needles and threads to save the trouble of repeatedly changing needles and threads. In the absence of traditional stitched card joints, the textile fabric can be neatly divided and partially sealed, and the stitching colleagues also play a role. The effect of decoration, the strong adhesion can achieve the actual effect of waterproofing, the embossing is clear, the surface layer has the actual effect of three-dimensional relief, the working speed is fast, the equipment effect is good, and the high-end and beautiful appearance.
2. Using ultrasonic and special steel wheel processing, the sealing edge does not crack and does not damage the edge of the cloth, and there is no burr or curling phenomenon.
3. No preheating is required during manufacture, and it can be operated continuously.
4. The actual operation is simple, and it is not much different from the actual operation method of the traditional sewing machine. The fully automatic equipment can be used directly with simple practical operation knowledge.
5. Low cost, 5 to 6 times faster than traditional machines, and high efficiency.
