AI Technical Summary
In the current process of perforating and sampling tobacco leaves, round tobacco leaves are prone to getting stuck inside the punch, which makes it inconvenient for workers to pick them up and reduces work efficiency.
A tobacco leaf punching and sampling device was designed, comprising a support base, a device housing, and sampling components. By utilizing a combination of gear transmission and helical springs, the punch can be automatically reset and the tobacco leaves can be automatically ejected. The gear transmission converts manual labor into mechanical power, ensuring the convenience and accuracy of the sampling process.
It enables automatic unloading of tobacco leaf samples, improving operational convenience and efficiency, reducing manpower consumption, ensuring the accuracy and consistency of sampling locations, and reducing sampling errors.
