Description

Technical Field

[0001] The present invention relates to the technical field of packaging equipment, and more specifically, to a vertical packaging machine for straight sanitary napkins. Background Art

[0002] At present, the operating speed of sanitary napkin production equipment is generally high. Under normal circumstances, the production volume can reach hundreds to 1,500 pieces per minute. However, the production line can only complete single-piece small packaging, that is, the products produced are packaged in single-piece small packages. In the future, the small packages still need to be packaged together in packaging bags according to certain quantity requirements to form the final products sold on the market. Therefore, the single-piece small package products of sanitary napkins still need to go through the processes of stacking, conveying, and packaging bags before they can be put on the market.

[0003] For each process in the above packaging stage, the current operation method is to separate these processes, first perform stacking by manual operation, and then use the packaging machine for packaging; because the production line is a continuous high-speed production, it is impossible for humans to directly receive small packages of products from the machine and count and stack them. Therefore, the current operation method is generally to set up a rear workbench at the end of the production line, stack the small packages of products on the workbench, and then manually count and stack them, and put them into the packaging machine for packaging. Each production line generally needs to be equipped with 6 to 8 packaging workers to make the packaging speed compatible with the production speed; it can be seen that the traditional sanitary napkin production line requires more manual operations, the production cost is high, and the production efficiency is difficult to further improve; for this reason, we propose a vertical packaging machine for straight sanitary napkins.
