For a long time, plastic bags have provided great convenience to our daily life, but the ecological and environmental problems caused by plastic bags should not be underestimated. Its low recycling value has become known as white waste. In my country, a ban on plastic bags has been gradually announced. In this environment, non-woven bags are quickly used in households, shopping malls, medical equipment, institutions and other places due to their advantages of environmental protection, beauty, generosity, cheapness, and wide range of main uses. Non-woven bags have long been widely used in capitalist countries. Similarly, in China, energy-saving non-woven bags also have a tendency to replace polluting plastic bags. China’s industry prospects continue to be optimistic about the implementation of the ban on plastics. So far, shopping malls rarely see people using a lot of plastic bags to take their goods home, and environmentally friendly shopping bags of different materials have gradually become the new favorite of contemporary people.
So what machinery and equipment must be used in the manufacture of non-woven bags, and what is the processing technology? Here, Lehan’s small classes give us a simple demonstration. At this stage, the manufacture of non-woven bags generally adopts the principle of ultrasonic waves. According to different functions, it is divided into manual non-woven bag machines and automatic non-woven bag machines. Generally speaking, the following mechanical equipment must be added to the manual production line: non-woven bag machine, non-proof cloth cutting machine, punching machine, wristband automatic welding machine. Taking Lihan automatic non-woven bag machine as an example, its production process is introduced in detail:
1. Basic production process.
The basic production process of automatic non-woven bag machine is feeding (no tarpaulin waterproof membrane) → folding → ultrasonic bonding → cutting → making packaging bags (punching) → waste recycling → counting → palletizing. This step can be a time automation technique. As long as 1~2 operate by yourself, you can adjust the manufacturing speed and equipment specifications within a certain range. Apply touch display operation, cooperate with industrial automation equipment such as step-type fixed length, optical tracking, automatic counting (counting alarm can be set), and automatic opening. In order to better fulfill the role of green environmental protection, friends can recycle waste during the production process, and automatically collect the remaining waste in the production process of making packaging bags, which is conducive to secondary use.
Features of automatic non-woven bag making machine.
The design scheme has excellent technology, fast manufacturing speed and high efficiency. Different specifications and models can be produced and processed. Different styles of environmentally friendly non-woven bags with good quality and good adhesion strength.
1. Non-woven bag edge strip: press the edge of non-woven bag;
2. Non-woven bag embossing: the top of the non-woven bag and the border line are pressed together;
3. Non-proof cloth hand strap pressing: automatically press the handbag according to the sleeve specification.
Advantages of mechanical equipment:
1. Use ultrasonic welding for free needle and thread, saving the inconvenience of frequent replacement of needle and thread. Textiles also allow for clean partial cuts and seals without traditional surgical sutures to disconnect connectors. Surgical suture friends also played a decorative role. Good adhesion can achieve the actual effect of waterproofing. The embossing is clear, the surface has the actual effect of three-dimensional relief, and the working speed is faster.
2. Using ultrasonic and special small-scale production and processing, the sealing edge will not crack, the cloth edge will not be damaged, and there will be no burrs.
3. No heating required during manufacture and can run continuously.
4. The operation is simple, not much different from the traditional electric sewing machine operation method. With simple operating expertise, automated assembly lines can get started right away.
5. The low cost is 5 to 6 times faster than traditional equipment, and the efficiency is high.
