Technical Field

[0001] This utility model belongs to the field of logistics information confidentiality technology, and in particular relates to the roller coating mechanism of the express waybill information coverer. Background Technology

[0002] With the rapid development of the logistics industry, the information privacy protection requirements for express delivery waybills, as key carriers of sender and recipient information, waybill numbers, and logistics data, are increasing. Traditional express delivery waybill information covering technologies are mainly based on manual application, pre-printed overlays, or electronic tag replacement. In existing technologies, express delivery waybill information covering mainly relies on manual application of ink or the use of fixed-size roller stamps.

[0003] However, this type of device has the following drawbacks: Uneven application: The ink capacity of existing roller stamps is fixed, and after prolonged use, the ink is prone to drying out or leaking, resulting in uneven coverage and the possibility that personal information may still be reproduced. Limited size: Fixed-size application rollers cannot adapt to different sizes of express waybills (such as small registered mail slips and large logistics slips), requiring frequent tool changes and cumbersome operation. Inconvenient maintenance: The ink cartridge and application mechanism are mostly integrated designs, requiring replacement of the entire unit when the ink is depleted, resulting in high maintenance costs.

[0004] To address these issues, we have provided a roller coating mechanism for a waybill information coverer. Utility Model Content
