Round finding machine is one of the main equipment for producing plywood, which can be divided into card based round finding machine and card free round finding machine (card free hydraulic round finding machine and large gear round finding machine). Card free round finding machine is time-consuming and labor-intensive, requiring three people to operate, and its work efficiency is low. With the advancement of technology, hydraulic round finding control technology has also been applied to round finding machine production. The emergence of hydraulic round finding machine not only improves the work efficiency of round finding for logs, but also requires only one person to operate. This solves the problem of round finding for logs, but with the drawbacks of large-scale production also showing, the fur in the round finding process is not uniform, resulting in the fur produced being only used in the power generation and paper industry. Subsequently, The emergence of large gear rounding machines has solved the above problems, but the rounding effect is not as good as hydraulic rounding machines. Currently, most people still choose hydraulic rounding machines. The rounding machine produced by our company has the characteristics of stable performance, solid material use, and excellent discharge. And the circular machine can be used in conjunction with other machines to achieve a production line completed by three people.
