Background

With the development of science and technology, most factories adopt automatic equipment for production during production, and the automatic production greatly saves manpower and material resources, so that automatic processing appliances are widely applied to various large production lines or production machines. The plate notching machine can generate a large amount of smoke dust in the cutting process, the smoke dust can pollute the indoor environment, and the phenomena of abrasion or blocking of equipment and the like can be caused, so that the smoke dust needs to be discharged as soon as possible. The dust hood is one of common appliances for automatic processing, the existing smoke dust exhaust mode is to use the dust hood to cooperate with a dust collector to exhaust air, the dust hood generally covers the grooving blade and is used in cooperation with the grooving blade, and the dust hood can directly suck away the smoke dust in the grooving process, so that the smoke dust is prevented from polluting indoor environment or damaging equipment. However, the existing dust hood is used for single-channel dust collection basically, and in the grooving process, a small amount of smoke dust falls on equipment due to insufficient suction force, the smoke dust leaks out, the dust collection effect is reduced, the equipment is damaged, and the health of workers is influenced. Meanwhile, due to insufficient suction force, smoke dust is easily accumulated on the inner walls of the dust hood and the pipe wall, and therefore, operators are required to frequently clean the dust hood and the pipe wall, and the production efficiency is seriously influenced.

Therefore, we propose a dust hood with vacuum amplification dust collection to solve the existing problems.
