Deviation-rectifying and material-collecting device for packaging bag

Abstract

The invention relates to the technical field of manufacture of packaging bags, in particular to a deviation-rectifying and material-collecting device for a packaging bag. The device comprises a tension roller and a material-collecting roller, wherein a limiting mechanism is arranged at the lower part of the material-collecting roller and mainly comprises a bottom plate, a left limiting plate and a right limiting plate; the left limiting plate is fixed on a left supporting rod; the left supporting rod is fixed on a pedestal; the right limiting plate is fixed on a right supporting rod; the right supporting rod is fixed on the pedestal; and the distance between the left limiting plate and the right limiting plate is the same as the width of the packaging bag. The device is simple in structure and convenient and quick to operate; and in the prior art, a moveable limiting mechanism is mounted below the material-collecting roller and can prevent the packaging bag from deviating leftwards and rightwards, so the rolling quality is improved and the whole appearance attractiveness of the packaging bag is improved.

Description

technical field [0001] The invention relates to the technical field of packaging bag production, in particular to a packaging bag deviation correcting and receiving device. Background technique [0002] At present, in the process of bag making and printing, it is necessary to print the packaging bag to be printed on the bag making machine, and collect the material after printing. In the prior art, the material receiving mechanism is mainly composed of a receiving roller and a tension roller. Place the receiving paper tube on the receiving roller, and the rotation of the receiving roller drives the paper tube to rotate to collect the packaging bag. In actual work, when the paper tube is wound, although a deviation correction device is installed on the equipment, the The packaging bag will still be offset, which will eventually affect the quality and appearance of the product.

[0002] At present, in the process of bag making and printing, it is necessary to print the packaging bag to be printed on the bag making machine, and collect the material after printing. In the prior art, the material receiving mechanism is mainly composed of a receiving roller and a tension roller. Place the receiving paper tube on the receiving roller, and the rotation of the receiving roller drives the paper tube to rotate to collect the packaging bag. In actual work, when the paper tube is wound, although a deviation correction device is installed on the equipment, the The packaging bag will still be offset, which will eventually affect the quality and appearance of the product. Although some manufacturers have added a limit device on the paper tube, it is relatively large in size on some large-scale receiving rollers, and the installation is more laborious.
