The Automatic Non-woven Bag Making Machine Embodies The Concept Of Green Environmental Protection.
Dec 06, 2018
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 non-woven 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 fully automatic non woven bag making machine to accumulate strength for the occupation of the future market.

The multi-functional fully automatic non woven bag making machine combines the automatic control system with the ultrasonic bonding application technology, and explores the 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, synchronous automatic cutting, automatic tension control, low production cost. The main technical parameters are as follows: production speed: 10-70 pieces per minute rated voltage: 380 V rated frequency: 50 Hz total power: about 15 kW shape size: about 9800 mm * wide 1800 mm * high 1600 mm equipment weight: about 4800 kg

Basic technological process: feeding (non-woven coil) folding ultrasonic bonding cutting bag (punch) 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. Multi-functional automatic non-woven bag making machine with step-by-step fixed length, photoelectric tracking (running accurately and smoothly), automatic counting (counting alarm can be set), automatic punching and other industrial control devices. At the same time, in order to further reflect the concept of energy saving and environmental protection, 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 bonding technology

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.

Ultrasonic bonding equipment is mainly composed of ultrasonic generator and roller. The main components of ultrasonic generator are horn, power supply and transformer. The horn, also known as the radiator, can concentrate sound waves on a single plane; the roller, also known as the anvil, is used to concentrate heat released from the horn of the ultrasonic generator. The bonded material runs continuously between the horn and the roller and is bonded together under a lower static force. The frequency converter converts electricity into high-frequency electrical energy, which is then converted into ultrasonic vibrator and finally into vibration energy. An amplifier amplifies the vibration energy to the horn, and the acoustic tool immediately contacts the material to be bonded. These superauditory frequencies cause mechanical pressure between the molecules of the material, release heat, destroy the molecular bonding in the material, cause the material to melt at the bonding point, and then bond two or more layers of material together by mechanical pressure.

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.

The multi-functional 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.
