Paper bag barrel pull-apart device of barrel-making machine

Abstract

The invention relates to a paper bag barrel pull-apart device of a barrel making machine. The paper bag barrel pull-apart device comprises a rack, and further comprises a front pull-apart mechanism and a rear pull-apart mechanism which are arranged on the rack; each of the front pull-apart mechanism and the rear pull-apart mechanism comprises a lower pull-apart part, an upper pull-apart part and amaterial breaking swing arm; the two ends of each lower pull-apart part are rotationally installed on the rack, two material breaking swing arms are arranged and one end of each material breaking swing arm is rotationally installed on the rack, and the upper pull-apart part is rotationally installed between the material breaking swing arms and located at the ends, opposite to the rack, of the material breaking swing arms; the rack is provided with a transmission assembly for driving the lower pull-apart parts and the upper pull-apart parts to rotate, and the conveying speed of the lower pull-apart part and the upper pull-apart part in the front pull-apart mechanism is smaller than that of the lower pull-apart part and the upper pull-apart part in the rear pull-apart mechanism; and the rack is further provided with a reciprocating mechanism for driving the front pull-apart mechanism and the rear pull-apart mechanism to synchronously press down and lift up, so that the influence on thetraction accuracy of the strip-shaped paper in the pull-apart process is reduced.

Description

technical field [0001] The invention relates to the technical field of paper bag tube production, in particular to a paper bag tube breaking device for a tube making machine. Background technique [0002] As we all know, paper is a recyclable resource. The raw materials for papermaking are mainly plant fibers. In addition to the three main components of cellulose, hemicellulose, and lignin, the raw materials also contain other components with less content, such as resin and ash. In addition, there are auxiliary ingredients such as sodium sulfate. In addition to plant fibers in paper, different fillers need to be added according to different paper materials. Commonly used plastic bags are made of polyethylene from petroleum, an already scarce source of energy for us. In contrast, paper bags are made from trees, a renewable resource. The characteristics of degradable and recyclable are naturally labeled with green labels. [0003] At present, a large number of paper bags ...

Problems solved by technology

[0004] The paper bag tube cuts out easy-break holes through the strip-shaped paper, and periodically contacts the strip-shaped paper by setting a set of tear-off mechanisms with fast transmission speed, so that the paper is broken along the easy-break holes to form a single However, due to the pulling force of the tearing mechanism on the paper during the breaking process, and the pulling force is applied to the paper, it will affect the normal traction of the paper and change the accuracy of the paper conveying in the paper tube machine sex
