如图1、2所示，一种四角定位裁切设备，包括皮带输送机100、分别设置于皮带输送机100的四个顶角的四角切膜机构200、设置于皮带输送机100上的光电检测开关500以及电控单元(图未示)，电控单元(图未示)分别与皮带输送机100、四角切膜机构200、光电检测开关500信号连接。
如图3所示，四角切膜机构200包括底板210、设置于底板210上的定位块一220、定位块二230以及裁切刀片240，定位块一220包括端面定位面221，定位块二230包括侧面定位面231以及裁切定位面235，定位块一220的端面定位面221与定位块二230的侧面定位面231垂直、与定位块二230的裁切定位面235在同一平面上，裁切刀片240贴靠定位块二230的裁切定位面235设置，裁切刀片240与裁切气缸250连接在裁切气缸250的驱动下沿着裁切定位面235向前或向后移动。
如图8-10所示，板材进入四角定位裁切设备中，光电检测开关500检测到板材进入皮带输送机100向电控单元发送检测信号，电控单元向皮带输送机100发送停止指令同时向四角切膜机构200发送裁切指令，皮带输送机100定位停止后，四角切膜机构200的定位块一220的端面定位面221抵靠在板材端面，定位块二230的侧面定位面231抵靠在板材侧面，裁切气缸250驱动裁切刀片240沿着定位块二230的裁切定位面235向前行走裁切与板材侧面连接的多余的复合膜以及被折压到板材底面的多余的复合膜，裁切刀片240触碰到定位块一220后裁切完成。
如图3-5所示，定位块一220还包括与端面定位面221相对设置的防护面225，防护面225的高度高于端面定位面221的高度使得板材在皮带输送机100定位停止后定位块一220的防护面225将板材端面的复合膜抬高。在此条件下，板材定位停止再皮带输送机100上时，落在定位块一220的防护面225上方的复合膜被防护面225抬高，避免裁切刀片240裁切复合膜时刀刃触碰到板材端面的复合膜。例如在实际应用过程中，定位块一220为自端面定位面221向防护面225逐渐升高的梯形体，或者定位块以220包括定位部以及高于定位部的防护部两部分组成。
如图6所示，皮带输送机100的两端分别设置有一组切膜宽度调整机构300，切膜宽度调整机构300包括两根平行设置的宽度调整导轨310，在两根宽度调整导轨310的两侧分别设置有一根宽度调节丝杆320，宽度调节丝杆320平行于宽度调整导轨310并设置于两根宽度调整导轨310之间，两根宽度调节丝杆320相对的一端分别连接有一块安装板330，安装板330通过滑块340与两根宽度调整导轨310连接，每块安装板330上设置有一套四角切膜机构200，安装板330在宽度调节丝杆320的推动下沿着宽度调整导轨310移动进而推动四角切膜机构 200在宽度调整导轨210上相向或相背移动以适应待裁切的板材的宽度。优选地，宽度调节丝杆320的另一端形成为宽度调节把手325，转动宽度调节把手325即可推动宽度调节丝杆320移动进而调节两块安装板330之间的距离。
优选地，皮带输送机100的第一端110设置有切膜长度调整机构400，设置于皮带输送机第一端110的切膜宽度调整机构300设置在切膜长度调整机构400上与切膜长度调整机构400滑动连接，设置于皮带输送机100的第二端120的切膜宽度调整机构300固定设置在皮带输送机100上。
如图7所示，切膜长度调整机构400包括分别设置于皮带输送机第一端110两侧的两根长度调整导轨410，每根长度调整导轨410上设置有一根调整机架420，调整机架420上装配有滑块430，滑块430可在长度调整导轨410上滑动，每根调整机架420与一根推动丝杆450连接，推动丝杆450通过长度调整丝杆460连接，长度调整丝杆460的一端形成为长度调整把手465，旋转长度调整把手465可推动推动丝杆450进而带动调整机架420沿着长度调整导轨410移动。设置于皮带输送机第一端110的切膜宽度调整机构300的宽度调整导轨310架设在切膜长度调整机构400上与调整机架420连接，调节长度调整丝杆460可推动调整机架420沿着长度调整导轨410移动进而推动皮带输送机第一端110的切膜宽度调整机构300移动以调节与皮带输送机第二端120的切膜宽度调整机构300之间的距离以适应待裁切的板材的长度。优选地，长度调整导轨410的长度为20～30cm。
优选地，四角切膜机构200的底板210底部安装有两根平行设置的定位导轨270，底板210底部装配有两组滑轮280，滑轮280可在定位导轨270中移动，底板210与定位气缸290连接在定位气缸290的驱动下沿着定位导轨270移动，四角切膜结构400的定位导轨270固定安装在切膜宽度调整机构300的安装板330上，板材在皮带输送机100上定位停止后，四角切膜机构200在定位气缸290驱动下向板材移动。
四角切膜机构200的定位导轨270与宽度调整导轨310成45度夹角设置于安装板330上，板材在皮带输送机100上定位停止后，四角切膜机构200在定位导轨270上向板材的对角线方向移动。
定位块一220与底板210中线的夹角为45度，定位块二230与底板210中线的夹角为45度。
