AI Technical Summary

Technical Problem

Due to the unreasonable structural design of the existing tape sealing machine, the cutting knife cuts the tape late, resulting in the residual tape being too long and extending to the handle on the side wall of the box.

Method used

A tape sealing machine tool holder device including a tool holder body, a knife cutting arm and an arc portion is designed. An arc is provided at the end of the cutting arm and the abutment position between the box, so that the cutting arm leaves from the tail end of the box in advance, and drives the cutting knife to rebound to cut off the tape in advance.

Benefits of technology

By cutting the tape in advance, the residual tape length is avoided, the impact on the handle of the side wall of the box is reduced, and the adhesive strength and sealing quality of the tape are improved.
