Description

一种防内卷卡纸结构及打印机 技术领域
本实用新型涉及标签打印机领域，具体的说，是涉及一种防内卷卡纸结构及打印机。
背景技术
压敏胶标签打印机在长期使用过程中，压敏胶标签的边缘会有少量的压敏胶溢出，标签底纸上的模切刀口处也会有微少溢胶。随着工业级标签打印机的长时间连续使用，这些溢胶会粘结积累在打印头的表面，然后会转移到打印机胶辊的表面。随着时间的增加，打印机胶辊粘结的压敏胶聚集增多，胶辊转动带动标签纸前行时因为胶辊表面压敏胶粘着标签底纸向下卷，进而进入打印机胶辊之下的内部标签纸不再前行，造成打印机卡纸，不仅维修麻烦，还有可能造成打印机硬件损坏。
为了解决这些问题，现有的打印机常采用防粘胶辊，减少标签内卷卡纸的故障。但是这样的结构没有从根本上解决标签内卷卡纸的问题。采用无离型底纸的压敏胶标签，压敏胶层会在打印头的位置与打印机胶辊加压接触，这时候会造成标签纸内卷卡纸，设备的故障率大大增加，阻碍了无底纸标签的推广应用。
上述缺陷，值得改进。
发明内容

更进一步的，所述胶辊窄缝的宽度和所述防卡纸挡片窄缝的宽度均为0.2mm。

具体实施方式
下面结合附图以及实施方式对本实用新型进行进一步的描述：
如图1所示，传统的打印机在进行打印的时候，打印头30下压标签纸10(尤其是无离型底纸的压敏胶标签)，使其与胶辊压接。标签压敏胶与胶辊的表面可能发生粘连，标签纸从胶辊与导纸台的缝隙中卷入打印机内部，进而造成标签内卷卡纸现象。
为了解决这个问题，本实用新型提供一种防内卷卡纸结构，如图2至图6所示，其包括胶辊和导纸台40，导纸台40位于胶辊的出纸一侧，在导纸台40与胶辊之间，固定安装若干个防卡纸挡片50，封堵胶辊与导纸台40之间的缝隙，阻挡标签内卷卡纸的通道，从而不会产生内卷卡纸。
1、胶辊
胶辊径向上开设有若干条胶辊窄缝23，胶辊窄缝23所在平面与胶辊的轴线垂直，即使得标签的走纸方向与胶辊窄缝23的方向平行。优选的，相邻两条胶辊窄缝23之间的中心间距为20-30mm，可以根据不同的标签大小及胶辊大小进行选择。
优选的，胶辊包括胶辊芯轴22及设于胶辊芯轴22外围的胶辊胶层21，通过胶辊胶层21进一步增加胶辊良好的导向作用。
胶辊窄缝23的宽度W1为0.2mm，胶辊窄缝23的结构设计不会影响标签的正常打印功能。
2、导纸台
导纸台40实现标签打印之后的出纸导向作用，其固定在打印机前端。优选的，导纸台40呈倒L字形，便于导纸台40的安装及固定。
导纸台40的前端固定有防卡纸挡片50，防卡纸挡片50的前端延伸进胶辊窄缝23内，横架在胶辊与导纸台40的缝隙之间，阻挡标签纸通过胶辊与导纸台40之间的缝隙内卷到打印机内部。本实用新型中的防卡纸挡片50的上表面低于胶辊的顶端，使得标签在打印后可以有短暂的缓冲时间，进而可以顺利进入防卡纸挡片50表面。优选的，胶辊窄缝23的深度H1为3-4mm，使其不会影响胶辊芯轴22的结构。防卡纸挡片50延伸进胶辊窄缝23内的深度H2为2-3mm，使得防卡纸挡片50能够充分发挥阻挡标签纸卷入打印机内部的作用，并且不会影响胶辊的正常转动。
具体的，导纸台40上纵向开设有若干防卡纸挡片窄缝41，防卡纸挡片50固定在防卡纸挡片窄缝41内。防卡纸挡片窄缝41前后贯穿导纸台40，使得防卡纸挡片窄缝41加工更加容易，且方便防卡纸挡片50的安装和固定。防卡纸挡片窄缝41与胶辊窄缝23一一对应，使得每个防卡纸挡片窄缝41中的挡板均延伸进对应的胶辊窄缝23中。
防卡纸挡片50插入防卡纸挡片窄缝41中后，滴入胶水，胶水渗入到导纸平台中，实现防卡纸挡片50与导纸台40的固定，此时防卡纸挡片50的上表面低于导纸台40的上表面。
优选的，胶辊窄缝23的宽度不小于防卡纸挡片窄缝41的宽度，可以使得防卡纸挡片50在固定到导纸台40上后，能够更加容易的插入胶辊窄缝23中。本实施例中的防卡纸挡片窄缝41的宽度W2与胶辊窄缝23的宽度W1相同，均为0.2mm。
如图6所示，防卡纸挡片50为片状金属结构，其前端沿着片状金属结构的宽度方向设有倾斜的斜面，使得防卡纸挡片50固定在导纸台40并延伸进胶辊窄缝23中后，前端的斜面与胶辊芯轴22的位置相配合。
具体的，防卡纸挡片50选用长度L为10-15mm的黄铜片或不锈钢片。防卡纸挡片50厚度W3为0.18-0.2mm，该厚度与胶辊窄缝23、防卡纸挡片窄缝41的宽度相匹配，使得防卡纸挡片50固定更加简便。防卡纸挡片50的宽度H3为2mm，能够配合胶辊窄缝23的深度进行安装。
本实用新型的防内卷卡纸结构可以应用于多种场合，例如打印机中。具体的，一种打印机，包括机架，机架内设有上述的防内卷卡纸结构。本实用新型通过将防卡纸挡片50从导纸台延伸进胶辊的内部，架在胶辊与导纸台的缝隙之间，完全阻挡了标签纸内卷进入打印机内部卡纸的通道，从而不会产生内卷卡纸的打印 机故障；可以应用于无离型底纸的压敏胶标签的打印场合，有利于无离型底纸的压敏胶标签的推广应用，降低了标签的生产成本，减少用纸，降低碳排放。
应当理解的是，对本领域普通技术人员来说，可以根据上述说明加以改进或变换，而所有这些改进和变换都应属于本实用新型所附权利要求的保护范围。
上面结合附图对本实用新型专利进行了示例性的描述，显然本实用新型专利的实现并不受上述方式的限制，只要采用了本实用新型专利的方法构思和技术方案进行的各种改进，或未经改进将本实用新型专利的构思和技术方案直接应用于其它场合的，均在本实用新型的保护范围内。
