AI Technical Summary

Technical Problem

The existing buffer paper pad rolling device cannot adapt to different carton sizes. The buffer paper pad roll after rolling is not tight and the tape sticking is insufficient, resulting in low packaging efficiency and inconsistent effect.

Method used

The floating material groove structure is adopted. Through the coordination of the rotating shaft and the limiting plate, the material groove can change from horizontal state to non-horizontal state with the rotating shaft as the swinging center. The resetting component ensures that the material groove is close to the buffer paper pad roll, the tape mechanism ensures that it is firmly pasted, and the roll material is removed when the material groove and the buffer paper pad roll are separated.

Benefits of technology

The consistency of the tightness of the buffer paper pad roll in different diameter ranges is achieved, adapting to different carton sizes, improving the packaging efficiency and the firmness of the tape paste, and preventing the buffer paper pad roll from spreading.

Abstract

The present invention discloses a floating trough structure for winding a buffer paper pad and a buffer paper pad winding device. The floating trough structure includes a trough, a rotating shaft, a limiting plate, a driving mechanism, and a reset component. The trough can swing from a horizontal state to a non-horizontal state. The driving mechanism can drive the limiting plate to swing with the rotating shaft as the swing center. The reset component can drive the trough to maintain a tendency to swing from a non-horizontal state to a horizontal state. The buffer paper pad winding device includes a winding mechanism and a floating trough structure. With the floating trough structure of the present invention, regardless of whether the buffer paper pad roll wound by the buffer paper pad winding device has the minimum diameter or the maximum diameter, the trough is tightly attached to the outer periphery of the buffer paper pad roll, and the tightness can be guaranteed. The diameter of the buffer paper pad roll wound by the buffer paper pad winding device can be changed between the minimum diameter and the maximum diameter, and it can ensure that the adhesive tape is firmly adhered and wound around the outer periphery of the buffer paper pad roll to prevent the buffer paper pad roll from unraveling.
