Protection management regulations：
The tape machine protection installation must meet the following requirements:
3. At least one set of anti-running switch shall be installed at the head, middle drive and tail of the belt machine; the delay of the belt machine's deviation switch shall not exceed 2S, and the deviation protection test shall be performed once a week, and the record shall be made; A deviation tester (installation height exceeding 1.8 m) at the elevated position of the belt conveyor must be equipped with a drawstring test device. The definition of the deviation of the belt machine: the upper surface of the upper belt is out of the upper roller for the deviation, and the lower belt is the deviation of the belt.
4. At least two sets of anti-ripping protection shall be installed at each receiving point of the tape machine. The tear-proof protection distance shall not exceed 5 meters. The longitudinal tearing of the rope shall be placed in the middle of the vertical tearing of the pirated sheet. Rope plus travel switch form and two logic "AND gate" flap cleaner plus travel switch form;
5. When the tape machine installation length exceeds 100 meters, at least one pull-type emergency stop switch should be set every 100 meters, and one intelligent amplified telephone should be set every 200 meters; all locked and amplified telephones should have a locking function, and Number management along the line and the amplified telephone.
Commonly used BOPP films include: ordinary biaxially oriented polypropylene film, heat-sealed biaxially oriented polypropylene film, cigarette packaging film, biaxially oriented polypropylene pearl film, biaxially oriented polypropylene metallized film, matte film, and the like. The performance parameters and main uses of the various films are as follows:
Ordinary BOPP film
