Description

Technical Field

[0001] This utility model relates to the field of laser cutting equipment technology, specifically to a ventilation device for the outer casing of a fully protective laser cutting machine. Background Technology

[0002] A laser cutting machine is a device that uses a laser beam to cut various materials. It achieves this by focusing a high-energy-density laser beam onto the surface of the material, causing it to melt, vaporize, or burn instantly. It is widely used in metal processing, automotive manufacturing, aerospace, electronics, medical devices, advertising signage, and many other fields for cutting metal sheets, pipes, profiles, as well as non-metallic materials such as plastics, wood, leather, and glass.

[0003] Over the decades of development in the laser cutting industry, cutting techniques have continuously improved, and the power of the lasers used has increased daily. However, this has also led to a significant increase in the amount of smoke generated during the cutting process. At the same time, as people's living standards continue to improve, their requirements for the operating environment have become increasingly stringent. Employees desire to work in a clean and safe environment, hoping to reduce the health hazards of smoke and pursue higher work efficiency and quality.

[0004] To meet these needs and achieve a good operating environment with minimal smoke, while also considering economic efficiency, effectiveness, and aesthetics, it is crucial to develop a laser cutting machine exhaust system with high-efficiency ventilation capabilities. This system should effectively remove smoke generated during the cutting process, maintaining a clean and comfortable working environment. Furthermore, it should have a compact design to save space; low cost for widespread application; practicality and reliability for long-term stable operation; flexible installation for easy integration with various laser cutting machines; and an attractive appearance that harmonizes with the overall workplace environment. Utility Model Content

This system offers efficient smoke extraction, improves the cleanliness of the working environment, provides multiple monitoring and control functions, is flexible to install, and has an attractive appearance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an exhaust device for a fully protective laser cutting machine outer casing, comprising a housing, a blowing device, and an exhaust device. The housing covers the outer periphery of the laser cutting machine. The blowing device is located at the upper end of the housing and communicates with the inner periphery of the housing. The exhaust device is located at the lower end of the inner periphery of the housing and communicates with the external flue. The blowing device assists the exhaust device in blowing air into the inner periphery of the housing, so that the smoke and dust generated during the laser cutting process are drawn to the external flue via the exhaust device.

[0007] As a further explanation of this technical solution:

[0008] Preferably, a front cover plate is movably provided at the front end of the top of the outer shell, and a rear cover plate is movably provided at the rear end of the top of the outer shell.

In addition, the rubber curtain around the lower end of the outer shell extends downward to be flush with the ground, which enhances the sealing of the inner circumference of the outer shell. In conjunction with the blowing device, it further assists the exhaust device in drawing the smoke and dust to the external flue, effectively reducing the accumulation of smoke in the working environment and achieving a highly efficient smoke exhaust effect.

[0017] Secondly, the design of this utility model can reduce the leakage of smoke and dust into spaces outside the work area, making the work space cleaner and tidier, greatly improving the cleanliness of the work environment, providing a good operating environment for enterprise employees, and reducing the harm of smoke to the body.

[0018] Thirdly, this utility model has multiple monitoring and control functions. The front door located in the middle of the front end of the outer shell facilitates the operation and maintenance of the equipment. The monitoring device located on the right side of the outer shell is used to monitor the inner circumference of the outer shell. The control device is electrically connected to the laser cutting machine and can control the operation of the laser cutting machine. The hazard alarm light at the top of the monitoring device is used for monitoring the operation of the laser cutting machine and for fault alarms. In addition, the observation windows symmetrically arranged on the left and right sides of the outer shell assist the monitoring device in observing the inner circumference of the outer shell, enabling operators to understand the operation of the equipment in a timely manner and improving the safety and reliability of the equipment.

[0019] Fourth, the blowing device of this utility model includes an even number of reinforcing air ducts, which are evenly distributed on the left and right sides of the upper end of the outer shell; the exhaust device includes an even number of exhaust fans, which are symmetrically and evenly distributed on the left and right sides of the lower end of the inner circumference of the outer shell. This design makes the device flexible to install and easy to use with various laser cutting machines. At the same time, the overall design of the outer shell focuses on aesthetics and can be coordinated with the overall environment of the workplace.

[0020] Fifth, the lower end of the outer shell of this utility model is provided with 2 to 8 support feet evenly on the left and right sides respectively. The multiple support feet cooperate with each other to provide stable support for the outer shell, ensuring the stability and safety of the equipment during operation.
