The safety grating is a photoelectric sensor that senses changes in light when a human body or object passes through, thereby triggering an emergency shutdown mechanism at a critical time to protect the safety of the operator. In the servo electric screw press, the safety grating is mainly set in the operating area, covering the dangerous area to prevent the operator from entering or accidentally touching the equipment.

First, the application and advantage of safety grating in servo electric screw press

In the servo electric screw press, the application of safety grating is mainly reflected in the following aspects:

Prevent operators from entering dangerous areas: In the operation area of the servo electric screw press, there are some dangerous areas, such as rotating screws, moving sliders, etc. These areas are dangerous for operators and may result in personal injury once entered. The safety grating covers these dangerous areas and is able to sense changes in light as the human body passes through. Once a person enters a dangerous area, the safety grating will immediately trigger an emergency shutdown mechanism, thereby protecting the safety of the operator.

Prevent equipment overload: The servo electric screw press needs to bear extreme pressure and load during operation. Once the equipment is overloaded, it may lead to serious consequences such as screw breakage and slide off, which may cause significant damage to the operator and the equipment itself. The safety grating can detect the abnormal situation of the equipment in time through the real-time monitoring of the pressure and load, and immediately trigger the emergency shutdown mechanism to avoid the occurrence of accidents.

Timely detection of foreign bodies such as metal fragments: During the molding process of refractory bricks, foreign bodies such as metal fragments and stones may be mixed into the material. These foreign objects under high pressure can cause injury to equipment and operators. The safety grating can detect these foreign objects in time and immediately trigger the emergency shutdown mechanism to avoid potential safety risks.

It is very important to choose a good quality grating. High quality gratings with higher sensitivity and faster response times can accurately trigger the shutdown mechanism at critical moments, thus effectively protecting the safety of the operator. In addition, high-quality gratings also have stronger durability and longer service life, which can ensure that the equipment remains in good working condition during long-term use.

2. Actual case presentation

When the servo electric screw press was used in a refractory brick factory, the equipment was overloaded due to the operator's misoperation. Fortunately, the factory installed safety gratings on the equipment. When the equipment is overloaded, the safety grating quickly triggers the emergency shutdown mechanism, avoiding equipment damage and casualties. After the accident, the plant strengthened the training and education of its operators and raised their safety awareness. At the same time, they have also strengthened the maintenance and overhaul of equipment to ensure the normal operation of equipment and the safety of operators.
