Description

TECHNICAL FIELD

[0002] At present, the existing paper bag production generally adopts a combination of a tube making machine and a bottom pasting machine to complete the automatic processing of the paper bag. The tube making machine is used to make a strip-shaped paper into a paper tube with both ends through, and the bottom pasting machine is used to seal the end of the paper tube. The finished paper bag can be directly filled and packaged.

[0003] The existing technology generally stacks the paper tubes sent out by the tube making machine into a paper tube stack for use by the bottom pasting machine. Since the glue in the paper tubes sent out by the tube making machine needs to be naturally cooled and solidified before being delivered to the bottom pasting machine, the conventional method generally places the paper tube stack still for a period of time. However, this requires a large storage area and needs to handle the paper tube stack multiple times, which reduces the production efficiency and causes the paper tube stack to be easily loose, resulting in the displacement of the paper tubes and affecting the subsequent processing. In addition, since the bottom pasting machine needs to stack the paper tube stack from top to bottom for feeding, the bottom pasting machine processes the material from the bottom of the paper tube stack. The existing conveying equipment is difficult to match and connect the feeding of the tube making machine with the feeding mode of the bottom pasting machine, and manual assistance is needed to stack the paper tube stack to the feeding port of the bottom pasting machine, which is low in efficiency and high in labor intensity.
