Problems solved by technology

[0018] In the corner bottom bag making machine with the above-mentioned existing bag bottom forming device, there are disadvantages such as the following: when general printing paper is used as bag paper for bag making in order to print on the bag surface, due to this paper thinner than bag making paper
Wrinkles are prone to occur during bag making, thus deteriorating corner bottom forming accuracy
In addition, due to the thinness of the paper, the paper tends to be messy and unstable during transportation. Therefore, failures such as abnormal transportation occur, which makes the bag making process difficult. Even if the bag can be made, the production speed is slow and the production efficiency deteriorates.
In addition, it is also easy to produce unevenness on the surface of the produced bag. Due to the unevenness, even if it is printed with a printing machine, it cannot be run in the printing machine.

Abstract

The paper bag making machine for making smooth bag with thin paper includes one paper barrel feeder, one fold line forming device to form the corner line of bag, one first bottom developing device to develop one end of the paper barrel, one second bottom developing device, one pressing device, one pasting device, one folding and erecting device, one folding-in device, and one conveying device. The paper bag making machine is provided with several folding and cutting devices for forming bottom folding line, bottom turning and folding line and side folding line separately.

Description

Technical field [0001] The present invention relates to a corner-bottom bag making machine for continuously forming, for example, candy bags, medicine bags and other corner-bottom paper bags. Background technique [0002] Such a bag making machine is disclosed in Japanese Patent Application Publication No. 11-091004 and Japanese Patent Application Publication No. 7-164579. For example, the bag making machine published in JP 11-091004 Bulletin has the following structure: [0003] That is, it has a paper tube forming device and a bag bottom forming device. The paper tube forming device folds the paper bag paper into two folds and adheres to each other, and folds its two sides inward into an M shape, and forms a paper tube with M-shaped pleats formed on both sides; the bag bottom forming device The corner bottom portion of the paper tube formed by the paper tube forming device is formed. [0004] In addition, the bag bottom forming device has: a supply device for continuously supply...
