Abstract
一种陶瓷喷墨打印机机头升降机构,包括伺服电机(4)、蜗轮蜗杆减速机(3)和支撑组件。支撑组件的数量为两组,每组支撑组件均包括传动横连杆(5)、连接轴(13)、丝杆组件、第一换向器(6)、第二换向器(16)、第三换向器(17)以及若干联轴器(8)。伺服电机(4)通过蜗轮蜗杆减速机(3)加大输出力矩后传递力矩到丝杆组件上,从而带动机头内框组件(2)上下移动。
Description
本发明涉及陶瓷喷墨印刷技术,尤其涉及一种陶瓷喷墨打印机机头升降机构。
现有技术中的喷墨打印机机构升降采用在传送带下面的机架底部安装升降推杆机构,利用推杆机构向上推力,从下面顶升整组机头部件,使其上下升降。为达到机头升降平衡,需要跨开传送带安装两组升降推杆机构,机头四角安装气弹簧辅助其受力平衡,来保证整个机头升降面精度,现有的机头升降机构具有如下缺点:
1.现有的机头升降机构利用顶升推杆机构在传送带下面顶升机头,其受制于传送带宽度来布局推杆机构,由于传送带宽度大,因此机头升降受力点只能在机头框架前后两端,其跨度大,容易产生变形;由于前后跨度大,而推杆机构安装在机架底部,因此对机架安装推杆机构面精度要求高,而对于焊接件的机架来说,有一定难度;而在整个机头中间前后各安装1推杆机构,受力点在机头中间,因此需要在机头框架中间设计加强筋,这样会影响整个机头通道组件的一致性,从而影响其外观及增加整个机头重量;
2.在机头四周安装气弹簧辅助其受力,有利有弊,不利地方为一方面增加升降电机负载,另一方面在升过程中,使机头框架凸变形,在凹过程中,使机头框架凹变形,当通道数越多,框架越长,其变形越大,甚至个别机器用肉眼都能看出其变形,这样便无法达到工作要求。
3.推杆机构体积大,重量重,成本高,已无法满足需求。
发明内容
为解决上述问题,本发明提供了一种陶瓷喷墨机机头升降机构,包括伺服电机、蜗轮蜗杆减速机、支撑组件;所述支撑组件的数量为两组,每组所述支撑组件均包括传动横连杆、连接轴、丝杆组件、第一换向器、第二换向器、第三换向器以及若干联轴器;所述丝杆组件的数量为两组;所述传动横连杆的一端与所述蜗轮蜗杆减速机的输出轴通过联轴器 连接;所述第一换向器包括两个水平输出端,所述第二换向器包括两个个水平输出端和一个垂直输出端,所述第三换向器包括一个水平输出端和一个垂直输出端;所述传动横连杆的另一端与所述第一换向器的其中一个输出端通过联轴器连接;所述第一换向器的另一个输出端与所述第二换向器的其中一个水平输出端通过联轴器连接;所述第二换向器的另一个水平输出端与所述第三换向器的水平输出端通过联轴器连接;所述第二换向器的垂直输出端与所述丝杆组件通过联轴器连接;所述第三换向器的垂直输出端与所述丝杆组件通过联轴器连接;每组所述丝杆组件包括丝杆和丝杆螺母,所述丝杆螺母套设在所述丝杆上;在所述丝杆螺母上设置有机头连接件,所述机头连接件与机头内框组件固定连接;在所述第二换向器上设置有换向器固定块,所述换向器固定块与机头外框架固定连接。
伺服电机通过蜗轮蜗杆减速机减速及加大输出力矩后,蜗轮蜗杆减速机一侧的输出轴的转动通过联轴器传递到传动横连接上,传动横连杆通过联轴器传送到第一换向器上,再通过第一换向器及联轴器传递到第二换向器上第二换向器的垂直输出端与丝杆组件连接,所以能够带动丝杆螺母上下移动,而丝杆螺母又与机头内框组件固定连接,从而机头内框组件能够上下移动,第二换向器与第三换向器通过连接轴和联轴器连接,另一组丝杆组件与第三换向器连接,从而能够带动另一组丝杆组件中的丝杆螺母上下移动;与蜗轮蜗杆减速机另一侧的输出轴连接的支撑组件的运动与上述运动类似。
优选的,所述陶瓷喷墨打印机机头升降组件还包括导向组件,所述导向组件包括导向滑块固定块、导向滑块、以及导轨,所述导向滑块固定块设置在机头内框组件的侧壁上,在所述导向滑块固定块上固定连接有导向滑块;在机头外框组件的垂直支撑架上设置有导轨,所述导向滑块在所述导轨上滑动;从而能够保证机头内框组件在垂直方向的移动精度。
优选的,所述导向组件的数量为四组,四组所述导向组件设置在打印机机头的四条侧边上。为了更进一步的保证机头内框组件在垂直方向的移动精度,在机头的四条侧边上均设置有导向组件,使得机头组件受力平衡。
优选的,在所述导向滑块上设置有滚珠,所述导轨包括一个凹槽,所述滚珠在所述凹槽内滑动。
优选的,在所述丝杆螺母的上方设置有轴承固定件,所述轴承固定件套设在丝杆上,所述轴承设置在所述轴承固定件上,所述轴承固定件与机头外框架固定连接。

优选的,所述机头连接件与机头内框组件的顶角固定连接。
本发明的有益效果如下:
1.用伺服电机搭配蜗轮蜗杆减速机作为升降动力源,通过联轴器、传动横连杆、换向器、连接杆,把所需扭力同步传送到负责垂直升降的滚珠丝杆机构上,上下移动的丝杆螺母与机头内框架组件连接,从而带动整个机头组件上下移动。这样设计不受限于传送带宽度,受力点布局更加合理,并且受力在机头框架两侧,提高通道组件分布一致性,外观改进,并且机头重量减轻。支撑组件固定在机头框架上,大大降低施工难度。
2.取消安装在四角的气弹簧,取而代之的是丝杆组件同时升降运动,这样更容易达到整组机头组件上下升降时的精度要求,避免了气弹簧会导致的机架框架受力变形。
3.顶升推杆机构体积大,重量重,成本高,用多个体积轻巧的换向器及丝杆组件取代,使整机布局更加合理,改善整机外观,并且降低成本。
