Description

工业喷码设备 技术领域
本发明涉及一种喷码设备，特别是涉及一种可很好的对不规则商品进行喷码 的工业喷码设备。 背景技术
在工业生产中许多物品在出厂前均需喷印公司相关有效期、 批号、 条形码、 图案、 商标、 计数、 班次、 文字等信息， 因此喷码设备运用比较广泛。 但在正常 使用时由于高清晰喷印机对使用的环境要求较高， 如 1、 现有的高清晰喷印机的 喷头的喷嘴直径较小（50 μ πι)， 从而要求其喷印的有效距离必须在 6mm内， 距离 越小喷印效果越好； 2、 喷头精度较高， 只能在无冲击、 振动的环境状况中使用， 这样喷头必须安装在无冲击、振动的固定支座上， 若喷头受到振动将导致空气进 入喷头的墨水腔内造成喷印内容不清晰甚至无喷印内容，因此使高清晰喷印机在 使用时受到了较多的限制。 由于高清晰喷码机有以上两个苛刻的要求， 导致高清 晰喷印机在生产线上应用时都采用固定安装方式，并通过整改生产线调整被喷印 物的位置来达到喷头的有效喷印距离， 若被喷印物的尺寸偏差大于 6mm， 那么就 得不到清晰的喷印内容， 甚至无法使用， 因此较大的限制了高清晰喷印机在不规 则物品上的应用。 以纸浆包为例， 现有高清晰喷码机的喷头支座固定安装在输送 带一侧， 由于被喷印产品自身的尺寸偏差为 ± 20讓， 而喷头的有效喷印距离必须 在 6mm内，因此经常发生被喷印产品与喷头的间距过大，喷印内容模糊不清问题， 或者发生被喷印产品与喷头相撞， 导致喷头剧烈振动， 从而使喷头墨水腔内含空 气较多， 使每个班都需频繁排墨净化才能排出喷头墨水腔内的空气， 按每天喷印 3000个商标为基准至少要净化约 92次， 平均每喷印 32个商标就要排墨净化一 次， 因此造成巨大的墨水损耗， 导致一瓶墨水只能喷印约 2917个商标， 平均每 个商标的喷印成本约为 1. 2元。 发明内容 本发明要解决的技术问题是： 提供一种可克服不规则物品引起的振动和冲 击， 使高清晰喷印机在不规则物品上良好工作的工业喷码设备， 可以克服现有技 术的不足。
本发明的技术方案是： 它包括输送带和高清喷印机， 在输送带的侧面安装固 定支架， 在固定支架上连接有导轨， 在导轨上配接有弧形板支架， 在弧形板支架 与导轨接触部位设有支架复位弹簧， 在弧形板支架上连接有弧形板， 在弧形板上 安装有高清喷印机， 且在弧形板中部开设有高清喷印机喷墨口。
所用的导轨为直线轴承导轨。
在弧形板支架上连接有直线轴承， 弧形板支架通过直线轴承与导轨配接。 支架复位弹簧套接在直线轴承导轨上， 且位于直线轴承的两侧。
直线轴承导轨与输送带前进指向的夹角 a 小于 90 ° 。
位于直线轴承的两侧的支架复位弹簧均处于压缩变形位置。
高清喷印机的喷墨头与弧形板外弧面的距离小于 6mm。
高清喷印机的喷墨头与弧形板的外弧面相齐平。
与现有技术比较， 本发明通过将高清喷码机安装在一块弧形板上， 弧形板通 过支架柔性连接在输送带一侧的固定支架上，这样在输送过程中物品先于弧形板 一侧接触， 在接触运行过程中弧形板支架会平稳压缩一侧的复位弹簧， 使输送物 品始终与弧形板接触， 此结构可以适应各种不规则物品。在输送物品与弧形板接 触， 且行至高清喷码机触发开关接触时， 高清喷码机瞬间运行完成喷码工作， 这 样就可满足喷印的有效距离必须在 6mm内的要求。物品继续随输送带前进， 弧形 板在复位弹簧作用下缓缓回位， 从而可避免高清喷码机的振动； 因此本发明可以 克服现有制约高清喷码机广泛推广的技术难题。安装在输送带一侧的导轨为直线 轴承导轨， 此种导轨具有阻力小、 造价低， 安装、 更换方便的优点。 在弧形板支 架上连接有直线轴承， 直线轴承与直线轴承导轨配合可以减少摩擦阻力。支架复 位弹簧套接在直线轴承导轨上， 且位于直线轴承的两侧， 这样设置可以使弧形板 始终处于平稳运行， 且能保持原位。 直线轴承导轨与输送带前进指向的夹角 a 小于 90 ° 这样可大大减小直线轴承的起动摩擦阻力和动摩擦阻力， 使弧形板能 沿着导轨平稳、轻盈地移动。高清喷印机的喷墨头与弧形板外侧的距离小于 6mm， 优选与弧形板的外弧面相齐平， 因喷墨头与被喷物品越近其喷墨效果越好。
同时申请人将本发明运用于纸浆包生产线后，基本上只需每 7天净化广 2次， 一瓶墨水可喷印 43750个商标， 平均每个商标的喷印成本约为 0. 08元， 因此采 用此发明后有效的避免了喷头受到冲击和振动， 大大地降低了排墨净化次数， 不 仅节约了墨水的用量而且还提高了喷印的清晰度， 又降低了操作工的劳动强度。 附图说明
图 1为本发明的结构示意图；
图 2为图 1俯视示意图；
图 3为图 1的 A向视图。 具体实施方式
实施例 1 : 如图 1、 图 2和图 3所示， 本发明安装在输送带 1的一侧， 其固 定方式可以为直接安装在输送带一侧， 也可在输送带 1的侧面安装固定支架 9， 在固定支架 9上连接有导轨 3， 所用的导轨 3为直线轴承导轨， 且在安装时直线 轴承导轨与输送带 1前进指向的夹角 a 小于 90 ° ， 在导轨 3上配接有弧形板支 架 4， 弧形板支架 4通过直线轴承 8与导轨 3配接， 且在弧形板支架 4与导轨 3 接触部位安装有两个型号相同的支架复位弹簧 5， 支架复位弹簧 5套接在直线轴 承导轨上， 且位于直线轴承的两侧并处于压缩变形位置 (如图 1) ; 在弧形板支架 4上连接有弧形板 6， 弧形板 6的弧度可根据被喷印产品与喷头间需要补偿的距 离来设计， 在弧形板 6上安装有高清喷印机 2， 且在弧形板 6的中部开设有高清 喷印机喷墨口 7 (如图 3)， 在安装高清喷印机时高清喷印机 2的喷墨头与弧形板 6外弧面的距离小于 6mm， 优选方案为高清喷印机 2的喷墨头与弧形板 6的外弧 面相齐平。
