Abstract

The invention discloses a perforating device of a paper bag making machine. The perforating device comprises a support. An upper pressing shaft and a lower pressing shaft are arranged on the support, an upper punching wheel and a traction pressing roller are arranged on the upper pressing shaft, and a lower roller is arranged on the lower pressing shaft. An upper punching knife is arranged on the upper punching wheel, a lower punching knife matched with the upper punching knife is arranged on the lower roller, and the upper pressing shaft and the lower pressing shaft move synchronously. A cavity is formed in the lower roller, the lower punching knife is communicated with the cavity, and thus waste paper generated after punching of the upper punching knife can enter the cavity. The cavity is connected with a waste removing fan. The perforating device of the paper bag making machine improves perforating efficiency and accuracy through a structural improvement, and is provided with a waste paper removing and recycling device.

Description

technical field [0001] The invention relates to portable paper bag processing equipment, in particular to a punching device for a paper bag machine. Background technique [0002] Due to the requirements of environmental protection, the use of plastic bags is limited, and paper bags are widely used in the outer packaging of commodities and people's daily life because of their environmental protection, aesthetics, and convenience of carrying. Paper bags with handles, which are easy to carry when in use, are more popular. [0003] During the mechanized production of paper bags with handles, operations such as folding, bottom folding, and gluing of paper are required. After the paper bag is produced, two holes are punched at the mouth of the bag, and the hand rope is inserted into the handle of the paper bag. . [0004] At present, the punching device of the traditional paper bag machine mainly uses another set of independent equipment, that is to say, a punching device is an ...
