Description

牙排定位装置和模切机 技术领域
本发明涉及一种定位装置和模切机，具体是涉及一种牙排定位装置和包括其的模切机。
背景技术
市场现有的多机组模切烫印设备(专利号ZL 200410093700.6)，利用多机组的模压单元和铝箔控制单元完成所需要的多次烫印(或压痕)和模切工作，极大提高了生产效率，缩短了生产周期。但是，由于该种设备的输送纸张通常由并列安装在牙排上的多组牙排进行叼纸输送，牙排叼纸以封闭循环的轨迹方式进入各个机组工位进行模压工作。由于封闭链条较长，且在长期使用过程中所受张力大小和方向频繁改变，导致链条形变的发生，链条累积误差的发生极大地降低了设备的加工精度。对于难于避免的由于链条形变误差导致的加工误差，现有的定位装置均无法做到适时微调，定位的偏差直接影响了后序加工精度。为了保证纸张的加工精度和质量，这就常常需要频繁的停机调节，这种调节方式费时费力，设备工作效率降低，人工成本提高。另外，当设备具有多机组工位时，往往需要对各个工位定位装置依次进行校核微调，纸张的定位方式繁琐且不精准。
由于现有技术是叼纸牙排定位方向与纸张运行方向是一致的，当叼纸牙排停止运动后，模切机的定位块会沿纸张运行方向顶住叼纸牙排的定位面，使牙排体和牙排连接件之间出现一定量的缝隙。当链条长期使用拉伸变长后，模切机的定位块需要先将链条的拉伸量克服掉后，再去对叼纸牙排进行定位，如果当链条拉伸量较大时，牙排定位会不到位(不会出现缝隙)，此时就需要更换新的链条。当叼纸牙排准备开始移动时，叼纸牙排会先沿纸张运行方向的反方向向后运动，然后才向前运动，这样就容易出现纸张在模切机内部散落的现象，造成报警停机。
