ZJ17卷接机组印刷系统喷墨装置的优化

目的 为了解决ZJ17卷接机组生产在线印刷钢印卷烟产品时，喷墨装置在设备停机再启动时的油墨外溢成团，造成的钢印印刷不清晰或钢印色差类废品率高问题。方法 从油墨截断方式、多余油墨储存、油墨喷嘴通道形状以及气路控制等方面入手，研发了一种新型喷墨装置。结果 既保证了正常生产时油墨的供应，又实现了喷墨量在设备重复启停时的有效控制，使钢印不清晰废烟量从优化前0.229 kg/箱降低到0.016 kg/箱，钢印色差废烟量从优化前0.219 kg/箱降低到0.013 kg/箱，有效降低了废品量。结论 该装置对提高卷烟产品质量、降低材料消耗、减少人工劳动强度具有显著效果，可以有效解决行业内在线印刷钢印卷烟产品生产普遍存在的问题。

Optimization of Inkjet Device for Steel Seal Printing System of ZJ17 Cigarette Machine

The work aims to solve the problem that the ink spills into a lump when the inkjet device was stopped and started again when ZJ17 cigarette machine was used to produce cigarette products with online steel steel printing, resulting in unclear steel seal printing or high scrap rate of steel seal printing color difference. A new inkjet device was developed from the aspects of ink blocking mode, excess ink storage, ink nozzle channel shape and gas path control. It not only ensured the supply of ink in normal production, but also realized the effective control of ink jet quantity when the equipment was repeatedly started and stopped, so that the discharged cigarette quantity of unclear steel seal was reduced from 0.229 kg/box before optimization to 0.016 kg/box, and the discharged cigarette quantity of steel seal chromatic aberration was reduced from 0.219 kg/box before optimization to 0.013 kg/box, effectively reducing the amount of discarded products. The device has significant effect on improving the quality of cigarette products, reducing material consumption and reducing labor intensity, and can effectively solve the widespread problems in the production of on-line printed steel seal cigarette products in the industry.
