According to the basic structure, the stretch wrapping machine can be divided into the following three types:
Simple type: the wrapping process is controlled manually. Goods are packed at a low speed. Roller carriage speed, turntable/arm speed, etc. cannot be adjusted. When packaging, the overlapping height of the film, the amount of flanging, the number of wrapping layers and the height of the goods to be packaged are all controlled by manual operation. And it cannot be connected with the production line.
Semi-automatic type: The wrapping and packaging process is controlled by manual and machine. Goods are packed at a lower speed. The speed of the spoke carriage, the rotation speed of the turntable/arm, etc. can be adjusted at any time. The overlapping height of the film, the amount of flanging, the number of wrapping layers and the height of the goods to be packaged can be set in advance during packaging, and a program is formed to automatically wrap the goods.
Fully automatic type: The wrapping and packaging process is automatically controlled by the machine (that is, the production line type). Goods are packed at a high speed. This type of packaging machine is directly connected to the conveyor belt on the production line. The wrapping process is controlled by the main control machine on the production line, which uniformly controls the movement of the goods to be packaged and the movement of the conveyor belt, and the packaging position can be automatically positioned; all The adjustment parameters are pre-set, and the cutting and control of the stretch film are fully automatic; and there are supporting safety facilities to ensure the personal safety of the staff.
