Four-wheel folding mechanism for long sides at bottoms of cigarette packets

Abstract

The invention discloses a four-wheel folding mechanism for the long sides at the bottoms of cigarette packets, and relates to the technical field of cigarette automatic packaging equipment. Thus, thetechnical problems of existing four-wheels, that original rotary folding devices are not applicable any more for increasing ironing effects and using ranges of cigarette packets, can be solved. The folding mechanism includes a fixing support; a telescoping rod is arranged in the fixing support; the fixing support is provided with folding arms; and linkage supports which are driven by the telescoping of the telescoping rod to drive the folding arms to do folding motion are arranged between the folding arms and the telescoping rod. A seat of an original elastic strip pulling mechanism is utilized as a fixing seat of the novel folding mechanism; through the arrangement of the folding arms on the fixing seat, the folding arms can be driven to lift or move downward by utilizing the back and forth moving telescoping rod of the original elastic strip pulling mechanism as a power mechanism; a folding plate on the folding arms folds the bottom sides of the cigarette packets; and when the cigarette packets move to the position that just entering a four-wheel, the folding plate moves downward, so that the folding of the long sides of the cigarette packets can be accomplished, and therefore, ironing time can be greatly increased, and low reform costs can be achieved.

Description

technical field [0001] The invention relates to the technical field of automatic cigarette packaging equipment, in particular to the improvement of the folding mechanism for folding the long side of the bottom of the cigarette pack before the cigarette pack enters the four-wheel mold box. Background technique [0002] Since the existing four wheels for cigarette packaging only have two heating plates, there is enough space beside the middle ironing plate to install a rotary folder, which rotates and folds the long side of the bottom of the cigarette package. , The cigarette package rotates with the four wheels, when the long side is folded by the rotary folder, with the rotation of the cigarette package, the opposite long side hits the edge of the middle ironing board, and then it is automatically folded. [0003] The existing four-wheel heating capacity can only meet the heating needs of ordinary cigarette packs, and does not have the heating capacity of new-style cigarette...

AI Technical Summary

Problems solved by technology

[0003] The existing four-wheel heating capacity can only meet the heating needs of ordinary cigarette packs, and does not have the heating capacity of new-style cigarette packs with thicker paper and greater glue volume. In order to improve the ironing effect of folded cigarette packs and increase The application range of the four-wheel heating device, after adding a right ironing board, the installation space of the original rotary folder is limited, the original rotary folder will no longer be applicable, and the seat of the original pulling spring mechanism and the telescopic rod moving back and forth will no longer be applicable Therefore, there is an urgent need for a multi-purpose folding mechanism that is low in transformation cost and can be used for both ordinary cigarette packs and new-style cigarette packs for long-side folding.
