Description

Technical Field

In the production process of counterweights, the existing production lines have a low degree of automation. After the press forms the counterweights, the connection between the scraping, painting, and laminating processes often needs to be completed manually. Due to the heavy weight of the counterweights, the production process of the counterweights is labor-intensive and the working environment is harsh. There are also potential safety hazards for the staff. Summary of the invention
