Description

自动调控刀片速度的切纸机
技术领域
本发明涉及一种切纸机，特别是一种自动调控刀片速度的切纸机。
背景技术
印刷厂在对纸张完成印刷后，需要对其进行裁剪，以去掉多余的纸张。然而现有的切纸机通常只设置有一个开关按钮，无法调节切纸机的输出的力的大小，或者是通过设置几个固定档位，使得每次切纸机在对纸张进行切除时所消耗的能源都是一样的，无法快速根据所切纸张的重量而做出相应的输出，当所需切的纸张很少时，所需的能耗也是固定不变的，提高了能源的消耗。因此，本发明存在着无法自动的快速调节切纸机的刀速和能源消耗大的问题。
发明内容
本发明的目的在于提供一种自动调控刀片速度的切纸机。它具有能够自动的快速调控刀片速度和降低能源消耗的特点。
本发明的技术方案：自动调控刀片速度的切纸机，包括机架，机架上设有切纸平台，切纸平台上方设有切纸机构；所述切纸机构包括液压装置，液压装置端部连接有刀片，且刀片与切纸平台垂直放置；所述切纸平台上设有压力传感器，压力传感器连接有控制器，控制器与液压装置相连。
前述的自动调控刀片速度的切纸机中，所述液压装置包括油箱，油箱连接有油泵，油泵连接有第一单向阀，第一单向阀连接有三位四通换向阀，且与三位四通换向阀的A端相连，三位四通换向阀的B端连接有第二单向阀，第二单向阀与油箱相连；所述三位四通换向阀的P端和T端分别连接有第一等量分流阀和第二等量分流阀，第一等量分流阀分别连接有第一液压缸和第二液压缸，且分别与第一液压缸和第二液压缸的进油腔相连，第二等量分流阀分别与第一液压缸和第二液压缸的出油腔相连；所述控制器与三位四通换向阀的控制端相连；所述第一液压缸和第二液压缸的伸出端分别连接有连杆，连杆与刀片相连，且刀片与连杆为可拆连接。
前述的自动调控刀片速度的切纸机中，所述控制器为PLC控制器。
与现有技术相比，本发明通过在切纸平台上设置压力传感器，并与控制器相连，压力传感器通过将在切纸平台上检测到的纸张重量的数据传输到控制器，控制器根据数据控制液压装置输出相应的压力，从而控制刀片的切纸速度在一个最适宜的状态，节省了电力资源的消耗，降低了生产的成本。而且，液压装置中采用了等量分流阀，并设置了两个液压缸，使得液压装置可以更好的分配输出力，更精确的控制。综上所述，本发明具有能够自动的快速调控刀片速度和降低能源消耗的特点。
