The e-commerce express sealing machine is a machine specially designed for the e-commerce industry to quickly seal airplane boxes, with a sealing speed of up to 20 boxes per minute. The Gu'erqi e-commerce express sealing machine adopts a double-sided belt drive, a polygonal design device to stabilize the movement seat, and automatically seals the bottom up and down. It supports the sealing of boxes numbered 1-13, effectively preventing adverse packaging effects such as box warping and tape misalignment. The sealing effect is smooth and beautiful. Meanwhile, the width and height can be manually adjusted according to the specifications of the cardboard box, making the operation simple and convenient. Not only can it solve the problem of a large number of packages and slow packaging during the peak season of e-commerce, but it also does not require any maintenance and can be used as long as it is powered on. It can be used for standalone operation or on assembly lines with accompanying drawings.
