[0002] A woven bag is a packaging bag woven from plastic flat wire. It usually uses polypropylene, polyethylene, etc. as raw materials. The plastic is made into flat wire through a special process and then woven into a shape. The woven bag has the characteristics of high strength, low cost, and large capacity. Although it looks relatively rough and has average moisture resistance, it is durable and affordable. It is widely used in industrial and agricultural fields and daily life. It can be used to package bulk items such as fertilizers, cement, and grain, and can also be used to store daily necessities such as clothing. When producing woven bags, in order to improve the production efficiency of woven bags, manufacturers often use cutting devices to divide the whole woven bag into multiple small woven bags.

When the spacing between the heating tables and the pressing wheels on both sides is adapted to the width of the processed woven bag, turn off the servo motor. By setting auxiliary components, the cutting device can heat-seal the edge of the woven bag before cutting, thereby reducing the problem of the edge of the woven bag being easily derailed when the woven bag is directly cut, and further increases the functionality of the cutting device.
