What are the safety protection devices of small precision film longitudinal stretching machine?

Publish Time: 2024-12-04

During the operation of small precision film longitudinal stretching machine, in order to ensure the safety of operators and the normal and stable operation of the equipment, a variety of safety protection devices are equipped.

First of all, the emergency brake device is an extremely critical protective component. Once the equipment has an abnormal situation, such as film jamming, motor failure or other emergencies, the operator can quickly trigger the emergency brake button to stop the stretching machine immediately to avoid further expansion of the accident. This brake device usually has the ability to respond quickly and brake reliably, and can cut off the power source of the equipment in an instant to ensure that the equipment is in a safe and static state.

Secondly, the safety door interlock device is indispensable. When the stretching machine is running, there may be dangerous factors such as high temperature and high-speed running parts in its working area. The safety door interlock device ensures that the safety door cannot be opened at will during the operation of the equipment; only when the equipment stops running and is in a safe state, the safety door can be opened to prevent the operator from accidentally touching the dangerous area when the equipment is running.

Furthermore, the temperature overload protection device is crucial to the heating system of the stretching machine. Since precise temperature control is required during the film stretching process, if the heating element fails and causes abnormal temperature rise, the temperature overload protection device will detect and cut off the heating circuit in time to prevent fire or damage to equipment components caused by high temperature, and also avoid serious impact on film quality due to temperature out of control.

In addition, there is a tension abnormality detection and protection device. During the film stretching process, the stability of tension is the key to ensuring uniform film stretching. When the tension sensor detects that the tension exceeds the preset range, the system will automatically adjust the stretching parameters or stop the equipment to prevent the film from breaking and splashing due to excessive tension, or uneven film stretching due to too little tension.

In addition, the equipment is also equipped with a leakage protection device to prevent the operator from being electrocuted by leakage caused by electrical failure. It can quickly detect the leakage current and cut off the power supply in a very short time to ensure the safety of personnel.

These safety protection devices cooperate with each other to build a solid safety line for the small precision film longitudinal stretching machine from different aspects, ensuring that the safety risks are minimized while efficiently producing the film, providing a safe and reliable working environment for the operator, and also ensuring the long-term stable operation of the equipment and the normal production order of the enterprise.
