[0002] With the rapid development of e-commerce, the logistics industry has placed higher demands on the efficiency of printing and attaching waybills. Manual filling and attaching methods are inefficient and prone to errors, making them unsuitable for the needs of e-commerce logistics. Therefore, automatic waybill printing technology has emerged. This technology integrates printing and labeling functions, enabling the instant generation and automated attachment of waybills, greatly improving the efficiency and accuracy of logistics processing. In e-commerce logistics scenarios, this automatic printing device can quickly process large volumes of order information, accurately print waybills, and attach them to packages, providing e-commerce companies with an efficient and convenient logistics solution and effectively addressing the challenges of e-commerce logistics.

[0003] However, the actual application of automatic waybill printing devices also faces some challenges and problems. Among them, paper jams are a relatively common technical problem. Due to the wide variety of parcels in e-commerce logistics, and the different materials and sizes of waybills, the paper feeding system of the printing device is greatly challenged. If the paper surface is uneven, curled, or wrinkled, or if the paper thickness is not set correctly, the print head may not feed smoothly, leading to paper jams. Paper jams not only affect printing efficiency but may also damage the printing equipment, causing inconvenience and losses to the logistics operations of e-commerce companies.

[0004] Therefore, we have made improvements to this by proposing an automatic express waybill printing device. Utility Model Content

The conveyor roller is supported by elastic force in a vertical direction that is perpendicular to the paper moving path. The highest point of the circumference of the conveyor roller is lower than the paper conveying path. The end of the conveyor roller is equipped with a motor that drives its rotation. The motor and the conveyor roller are synchronously subjected to elastic force.

[0009] The base is fixed on the printer, and a circular groove for the conveying roller to pass through is formed on the contact surface of the base and the U-shaped plate, and the self-rotation point of the conveying roller located at the circular groove is eccentrically arranged between the center of the circular groove and the conveying roller in a non-pressing state of the conveying roller by external force, and when the conveying roller is pressed by external force, the conveying roller rotates along the inner wall of the circular groove while self-rotating.

[0010] Preferably, a circular gear is fixedly connected in the circular groove of the U-shaped plate, and a gear is fixedly sleeved on the output end of the motor in the same vertical plane as the circular gear.

[0011] Preferably, when the conveying roller is pressed by external force, the gear is engaged with the circular gear.

[0012] Preferably, an inclined groove is formed in the opening direction of the printer towards the horizontal plate of the U-shaped plate, and the inclined groove extends to the end of the long side of the U-shaped plate to form a knife edge.

[0013] Preferably, a paper outlet groove is formed at the paper outlet end of the printer, and a chip removal groove is formed in the printer and communicated with the paper outlet groove.

[0014] Compared with the prior art, the present application has the following beneficial effects:

[0015] In the scheme of the present application:

[0016] In order to solve the problem of paper jam in the actual use process of the face sheet printing device in the prior art, the present application provides a rotating paper limiting structure, i.e. a U-shaped plate, which limits the movement direction of the paper before paper jam and pulls and cuts the paper jam part after paper jam through motor driving, so that the problem of paper jam is quickly solved, and the next paper strip setting is more convenient.
