The principle of non-woven equipment operation

Changshu Lihong Nonwoven Machinery Co., Ltd. will give you an example to understand the characteristics of non-woven bags and the principle of operation.

Non-woven bag making machine

Mainly used in the textile industry, it can process non-woven bags of different specifications and shapes such as vest bags, handbags, leather bags, etc. The following briefly introduces the relevant information of the non-woven bag making machine.

1. The principle of non-woven bag making machine

The non-woven bag making machine feeds powder (colloid or liquid) into the hopper above the packaging machine from the feeder. The introduction speed is controlled by the photoelectric positioning device. The roll of sealing paper (or other packaging materials) is passed through The guide roller leads to the lapel former. After being bent, the longitudinal sealer laps it into a cylindrical shape. The material is actively metered and filled into the finished bag. The transverse sealer will heat sealing and cutting together. The bag tube is pulled down intermittently, and finally a flat bag with three-sided sealing with overlapping longitudinal seams is formed, and the sealing of a bag is completed.

Second, the characteristics of non-woven bag making machine

1. The use of ultrasonic welding eliminates the need for needles and threads, saves the trouble of frequent needle and thread changes, does not have the disconnected joints of traditional thread stitching, and can neatly cut and seal the textile parts. The stitching also plays a decorative role. It has strong adhesion and can achieve waterproof effect. The embossing is clear. The surface has a three-dimensional relief effect. The working speed is good and the product is more high-end and beautiful; the quality is guaranteed.

2. The use of ultrasound involves the processing of special steel wheels, the sealing edge does not crack, does not damage the cloth edge, and there is no burr or curling phenomenon.

3. There is no need to preheat during production and can be operated continuously.

4. It is easy to operate, not much different from traditional sewing machine operation methods, and ordinary sewing workers can operate it.

5. Low cost, 5 to 6 times faster than traditional machines, and high efficiency.
