There are the following defects: it causes the workshop to occupy a large area, the workshop is untidy and untidy, and dust is easily generated. Long-term work has an impact on the respiratory system of the staff; the factory needs more feeding equipment to meet daily production needs, resulting in an increase in the production cost of the enterprise. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a central feeding system, which can centrally feed multiple production equipments through pipelines, thereby helping to improve production efficiency, reduce production costs, reduce environmental pollution, and reduce dependence on sites.
