Description

Technical Field

[0002] With the in - depth development of the concept of sustainable development and the increasing awareness of environmental protection among people, paper packaging bags (hereinafter referred to as paper bags) are becoming more and more popular in the market, and their use in many fields has increased significantly, including retail, food packaging, gift packaging, etc. Compared with plastic bags, paper bags are recyclable and biodegradable, having less impact on the environment. And paper bags can be designed in various colors and patterns, which can adapt to different brands and products, and at the same time provide additional publicity opportunities for brands; in addition, paper bags are usually stronger than plastic bags and can carry more weight, and the use of disposable plastic products has been prohibited or restricted in many regions, so paper bags are good substitutes for plastic products.

[0003] After the existing paper bags are processed by a paper bag machine, they are generally packed in boxes or packed after being manually separated and stacked. However, with the use of technologies such as servo control in paper bag machines, the bag - making speed is getting faster and faster. It is reported that the existing paper bag machines can manufacture 600 or more paper bags per minute. The packaging speed of manual packing has fallen far behind, requiring more labor input and with a greater labor intensity. Especially because the produced paper bags are in a folded state, the bottom of the paper bag is much thicker than the upper part. In order to pack neatly, a certain number of paper bags need to be stacked relative to each other before packing, that is, paper bag packing indexing. This process is not only time - consuming and laborious, but also requires the same number of paper bags in each stack to ensure the packing neatness, and manual indexing is very prone to errors.

[0004] Therefore, how to perform automatic indexing of paper bags, ensure the packing quality, and realize the automation of paper bag packing is an urgent problem to be solved in paper bag production. Summary of the Utility Model

[0033] The working principle of the present utility model is as follows: The paper bags prepared from the paper bag machine fall one by one onto the first paper bag receiving platform and are supported by the paper bag support baffle to stand upright on the first paper bag receiving platform. As the paper bags increase, the paper bag support baffle moves backward. When it is close to the paper bag limit baffle, a single stack of paper bags is formed. (It should be noted here that the number of paper bags included in each batch of single stacks of paper bags can be adjusted, but the number of paper bags included in the single stacks of packaging paper bags in the same batch is the same. For example, in a certain embodiment, every 50 paper bags form a stack, that is, a single stack of paper bags). After the paper bags on the first paper bag receiving platform form a single stack of paper bags, the first servo - motor starts to drive the first paper bag receiving platform to move, while the paper bag support baffle and the paper bag limit baffle remain in place. The first paper bag receiving platform drives the single stack of paper bags through the transfer channel formed by two horizontal limit plates to the second paper bag receiving platform of the paper bag turning mechanism.

[0034] The first stack of paper bag stacking units is transferred to the second paper bag receiving platform. The second servo motor drives the second paper bag receiving platform to rotate 90 degrees, and then after being flattened by the paper bag pressing plate, it enters the next process. After the second stack of paper bag stacking units is transferred to the second paper bag receiving platform, the second servo motor drives the second paper bag receiving platform to rotate and reset, turns this stack of paper bag stacking units by 90 degrees, and then after being flattened by the paper bag pressing plate, it enters the next process. The third stack of paper bag stacking units repeats the transfer method of the first stack of paper bag stacking units, and the fourth stack of paper bag stacking units repeats the transfer method of the second stack of paper bag stacking units, and so on, so that the directions of adjacent paper bag stacking units are opposite to facilitate subsequent overlapping and packing.

[0035] Generally speaking, for the automatic indexing device of the present utility model, the automatic stacking mechanism controls the number of paper bag stacking units through the cooperation of the paper bag support baffle and the paper bag quantity limiting baffle. The structural design is reliable, the indexing quantity of each stack of paper bags is consistent, and the neatness of the relative stacking and packing of paper bags is ensured. The neatness of the paper bag stacking during the transfer process is ensured through the paper bag limiting component, ensuring the orderly progress of the packing indexing process. And through the paper bag turning mechanism, it rotates automatically one by one, ensuring that the directions of adjacent paper bag stacking units are opposite, avoiding the confusion of manual packing directions. It saves labor costs, improves the packing efficiency, and ensures the packing quality at the same time, having good practical value and economic value.
