Strut-unfolding device for corrugated box

Abstract

The invention relates to the field of corrugated boxes and discloses a strut-unfolding device for a corrugated box. The strut-unfolding device comprises a table surface; the table surface is symmetrically provided with supporting seats; a supporting frame which is of a reversed-U-shaped structure is arranged between the supporting seats; the sides, far away from the supporting frame, of the supporting seats are each provided with a driving motor; rotating shafts on the driving motors both sequentially penetrate through the supporting seats and are in transmission connection with two vertical ends of the supporting frames; the middle part of the supporting frame is provided with a shaft sleeve in an embedding manner; a rotating shaft is inserted into the shaft sleeve; and the two ends of the rotating shaft both extend out of the shaft sleeve. The corrugated boxes which are in an unfolded state sequentially move down by virtue of a guide mechanism; a strutting block is used for opening folding parts of the corrugated box in a strutting manner so that a plurality of strutting rods can conveniently extend into the corrugated box when a quadrilateral component is in a totally closed state; the strutting rods can extend into the corrugated box in a falling process of the corrugated box; and thus the corrugated box can be conveniently unfolded in a strutting manner.

Description

technical field [0001] The invention relates to the field of corrugated cartons, in particular to a spreading device for corrugated cartons. Background technique [0002] Corrugated paper is one of the most widely used packaging products, and its consumption has always been the first among all kinds of packaging products. When corrugated paper boxes are sent to customers and stored by customers, they are usually stacked for the convenience of stacking. Only when the corrugated boxes are It will be unfolded and folded when in use. [0003] Most of the existing corrugated boxes are opened manually. For mass production in factories, not only the opening efficiency is slow, but also the labor intensity is high and it is easy to make people tired. [0004] The technical solution provided by the patent document CN208307240U improves the structure of the corrugated box, but the way of folding the corrugated box from the initial unfolded state into a box body remains unchanged.
