Plastic bags not only bring convenience to people's life, but also
constitute an important factor for the deterioration of human living
environment. Nonwoven fabrics are considered as the best substitutes for
plastic bags because of its short technological process, high yield,
rapid variety change, wide source of raw materials, long service life
and biodegradability. Some experts estimate that the shopping bags can
be reused more than 10 times, and the environmental pollution after
discarding is only 10% of plastic bags. Therefore, many machinery
manufacturers in China are actively engaged in the research and
development of non woven bag making machine to accumulate strength for the occupation of the future market. Main technical parameters
Fully automatic non woven bag making machine combines automatic control system with ultrasonic bonding technology, and explores a new non-woven bag making process. The equipment uses non-woven fabric as raw material, can process various specifications, different shapes of non-woven bags, such as vest bags, handbags, perforated bags, etc., with a multi-purpose advantage.
Non woven bag making machine adopts foreign advanced ultrasonic bonding technology, wireless sewing, automatic cutting synchronously, automatic tension control window sticker, low production cost. The non-woven bag is beautiful in appearance, firm in structure and strong in bearing capacity, up to 20 kg or so. The basic technological process: feeding (non-woven fabric coil) folding ultrasonic bonding cutting bag making waste recycling counting stacking. The process can be fully automated, only 1 to 2 people to operate, can be adjusted within a certain range of production speed and product size. The automatic non-woven bag making machine is equipped with industrial control devices such as step-by-step fixed length, photoelectric tracking (accurate and stable operation), automatic counting (set counting alarm), automatic punching, etc. At the same time, in order to further reflect the concept of energy saving and environmental protection, fully automatic non woven bag making machine has the function of recycling surplus materials in the production process, which can automatically collect the remaining waste materials in the production process, which is conducive to secondary utilization, reducing labor intensity and increasing work efficiency.
Ultrasonic technology in the textile industry from the original used for processing mattresses and mattresses, has been widely used in the non-woven industry. Ultrasonic energy belongs to mechanical vibration energy, more than 18000Hz, and beyond the range of human hearing. When applied to bonding thermoplastic materials, such as non-woven fabrics, the frequency is usually 20000Hz.
Compared with the traditional needle-type thread stitching, ultrasonic bonding is used to avoid needle and thread changing process, and there is no breakage joint of traditional thread stitching. The non-woven fabric can also be neatly cut and sealed locally. At the same time, ultrasonic bonding effectively avoids the degradation of fiber caused by thermal bonding, the influence of adhesive layer on the porosity of materials, and the delamination caused by liquid impact.
Fully automatic non woven bag making machine can not only produce non-woven environmental protection shopping bags suitable for shopping malls and supermarkets, but also process and produce non-woven environmental protection products such as non-woven suit dust cover, disposable slippers, shoe bags, tea tray mats, etc. At the same time, the vast number of machinery manufacturers in the development of non woven bag making machine process, should pay more attention to the non-woven bag processing costs and strength issues, so as to jointly stimulate the unlimited potential of the non-woven market, accelerate the progress of environmental protection.
