Description

Technical Field

[0001] The utility model relates to the technical field of packaging paper bag production, in particular to a packaging paper bag punching tool. Background Art

[0002] The outside of the fruit and vegetable packaging bag is perforated. First, it protects the fruits and vegetables in the package and reduces mechanical damage during transportation and sales. Second, the fruits and vegetables are still breathing in the plastic film, which reduces the concentration of oxygen in the package and increases the concentration of carbon dioxide, making the fruits and vegetables dormant to extend the storage period. The perforated packaging can adjust the humidity and gas composition in the package as quickly as possible, discharge the gas, water and heat generated by the metabolism of fruits and vegetables, maintain the respiration and other physiological activities of fruits and vegetables in a stable state, and reduce the humidity in the packaging bag, reduce the loss of water and nutrients in fruit and vegetable tissues, and reduce the occurrence of fruit and vegetable rot and deterioration, thereby achieving the purpose of extending the shelf life.

[0003] In the production process of fruit and vegetable packaging, continuous punching is required, but most of the punching equipment itself does not have the conveying capacity, and usually relies on an external conveying mechanism to continuously control the conveying of the packaging paper bags. Due to the separate setting of conveying and punching, the speed difference between the two during use will cause the offset of the punching position, affecting the scrap rate and causing waste. For this reason, we propose a packaging paper bag punching tool. Utility Model Content
