This film has layered structure, and the upper surface layer is suitable for being plated with aluminum on the upper surface, with higher optical performance and metallic texture.

[0003] This film has layered structure, and the upper surface layer is suitable for being plated with aluminum on the upper surface, with higher optical performance and metallic texture. In addition, the biaxially oriented polyester film for covering iron is a kind of film specially used for covering metal materials such as tinplate, chrome-plated iron and galvanized iron, suitable for various packaging and protection needs.
[0004] The manufacturing of biaxially oriented polyester film includes a slitting process, which is composed of a slitting device and a slitting machine control system.

Since it is a false action, the maintenance personnel cannot find the fault position, that is, they do not know the specific position of the fault. Therefore, the current method can only measure one point at a time, replace some parts or replace parts in batches, which wastes time and components. Often, it cannot fundamentally solve the problem and prevent it from happening again. INVENTION CONTENTS

[0022] The input side of the second connector J2 is connected with the first connector Jl, so that the signals of the first connector Jl in series in the control system of the film slitting machine are extracted. One end of the first normally open contact of each intermediate relay is connected with the output end of the second connector, and the other end of the first normally open contact is connected with one end of the coil of the intermediate relay. Each button switch is connected in parallel across the first normally open contact, and the other end of the coil of each intermediate relay is connected with the other end of the alarm unit, and the other end of each alarm unit is connected with the ground.
[0023] For example, the first normally open contact KIA of the first intermediate relay is connected with the first output end of the second connector J2, the other end of the first normally open contact KIA of the first intermediate relay is connected with the coil K1 of the first intermediate relay, and the first button switch SI is connected in parallel across the first normally open contact KIA of the first intermediate relay.
[0024] The first normally open contact KIA of the first intermediate relay is connected with the first output end of the second connector J2, the other end of the first normally open contact KIA of the first intermediate relay is connected with the coil K1 of the first intermediate relay, and the first button switch SI is connected in parallel across the first normally open contact KIA of the first intermediate relay.
[0025] The first normally open contact KIA of the first intermediate relay is connected with the first output end of the second connector J2, the other end of the first normally open contact KIA of the first intermediate relay is connected with the coil K1 of the first intermediate relay, and the first button switch SI is connected in parallel across the first normally open contact KIA of the first intermediate relay.

[0027] The first normally open contact KIA of the first intermediate relay is connected with the first output end of the second connector J2, the other end of the first normally open contact KIA of the first intermediate relay is connected with the coil K1 of the first intermediate relay, and the first button switch SI is connected in parallel across the first normally open contact KIA of the first intermediate relay.
[0028] Each alarm unit comprises an indicating lamp, which is connected in series with the coil of the intermediate relay. For example, the first indicating lamp L1 is connected in series with the coil K1 of the first intermediate relay, the second indicating lamp L2 is connected in series with the coil K2 of the second intermediate relay, the third indicating lamp L3 is connected in series with the coil K3 of the third intermediate relay, the fourth indicating lamp L4 is connected in series with the coil K4 of the fourth intermediate relay, and the fifth indicating lamp L5 is connected in series with the coil K1 of the fifth intermediate relay.
[0029] Since the working voltage of different film slitting machine control systems can be different, if the utility model is connected to the film slitting machine control system with different working voltages, the different voltages can bring adverse effects on the intermediate relay and the alarm unit. Therefore, the utility model further comprises a plurality of transformers, one transformer is connected in series between each first normally open contact and the second connector J2, and the voltage is transformed into a standard voltage that can be used by the intermediate relay and the alarm unit through the action of the transformer, so as to avoid damaging the intermediate relay and the alarm unit.

If any one of the third indicator lamp L3 and the third buzzer H3 emits alarm signal, it is proved that the third section circuit D3 is not faulty.
[0036] If the first segment circuit D1, the second segment circuit D2, the third segment circuit D3 are all not faulty, and after the fourth button switch S4 and the fourth key switch S14 are pressed, if the fourth indicator lamp L4 and the fourth buzzer H4 do not send the alarm signal, it proves that the fourth segment circuit D4 exists the fault.
