AI Technical Summary

Technical Problem

The existing balers lack limit devices and cannot be mechanically adjusted according to cargo of different specifications and sizes, resulting in users requiring real-time manual adjustment, which is very labor-intensive and inefficient. In addition, the gap at the middle junction will cause the cargo to stay, affect the operation of the machine and reduce efficiency.

Method used

A packaging device with a limiting structure is designed, including a limiting mechanism and a retention-proof plate. The limiting mechanism drives the movable baffle to move forward and backward through the meshing of gears and gear guides, thereby achieving limit fixation of goods. The anti-stagnation plate detects and drives the motor to drive the pendulum movement through a laser sensor, pushing the cargo stuck in the gap.

Benefits of technology

Through the use of the limiting mechanism, users' manual adjustment needs are reduced, labor intensity is reduced, and efficiency is improved. In addition, the anti-stagnation plate effectively avoids cargo trapping, ensures the normal operation of the machine and saves time.
