Description

Technical Field

[0001] The utility model relates to the technical field of carton folding mechanisms, and specifically relates to a carton packaging folding mechanism. Background Technique

[0002] As is well known, a folding carton is a very widely used green packaging container. Due to the characteristics of low processing cost, convenient storage and transportation, suitability for various printing methods, easy sales and display, suitability for automated packaging, good recyclability, and environmental protection, with the continuous improvement of people's living standards, the demand for folding cartons will continue to increase.

[0003] As Figure 1 shown, side flaps are provided on both sides of the existing carton (that is, the side tongues described in a carton bottom folding mechanism disclosed in Patent Application No. CN202321657504.1). When the existing carton packaging folding mechanism folds the side flaps, the lower pressing plate is pushed down by a cylinder to press down the side flaps, and the side flaps are folded only by the downward pressure. When the lower pressing plate returns, the side flaps easily rebound as Figure 2 shown, affecting the stability of the carton. Content of the Utility Model

[0014] beneficial effects:

[0015] 1. For the folding mechanism of the paper box packaging, through the arrangement of the telescopic device, the telescopic device can control the lower pressing plate to expand towards both sides. After the lower pressing plate presses down, the telescopic device is used to drive the lower pressing plate to expand towards both sides, and the lower pressing plate presses on the side baffle again;

[0016] 2. For the folding mechanism of the paper box packaging, through the arrangement of the driving motor, the lead screw, the mounting component and the hemming shaft. Then, while the lower pressing plate presses on the side baffle again, the driving motor rotates, the driving motor drives the lead screw to rotate, so that the mounting component and the hemming shaft move along the hemming position of the side baffle, and the hemming shaft hemms the hemming position of the side baffle again.

[0017] In summary, the present utility model can effectively prevent the side baffle from rebounding and improve the stability of the paper box. BRIEF DESCRIPTION OF THE DRAWINGS
