Description

一种四刀滚切装置 技术领域
本发明属于包装机械技术领域，具体地说是一种四刀滚切装置。
背景技术
在包装行业中，高效节能始终是永恒的话题，能否提高切纸速度，将对整机性能起到决定性作用；另外，切纸长度范围也非常重要。
现有技术中，每分钟超过200刀的切刀，在不定尺的要求下，还不能够较好地实现按照要求切出符合规定长度的纸张，即200刀/分钟以上的切纸速度无法实现。
发明内容
本发明的目的在于克服现有技术中存在的不足，提供一种结构简单、巧妙、合理的四刀滚切装置，该滚切装置不但能够提高切纸速度，还能够根据要求切出符合规定的纸张。
按照本发明提供的技术方案：一种四刀滚切装置，其特征在于：包括筒体，所述筒体上均布开设有四个切刀滑槽，每个所述切刀滑槽中均设置有一把切刀，所述切刀沿长度方向两端分别连接一根丝杆，每根所述丝杆均螺纹连接于一个涡轮的内螺纹孔中，所述涡轮与沿筒体轴向布置的蜗杆相配合；沿筒体径向同一直线上的两把切刀上的四根丝杆相互平行、交错布置；每一把切刀上与丝杆连接涡轮一端相对应处均开设有丝杆容纳腔。
作为本发明的进一步改进，所述丝杆完全收缩于丝杆容纳腔中时，与所述丝杆相连接的切刀收缩于筒体内。
作为本发明的进一步改进，所述涡轮转动限位固定于筒体内。
本发明与现有技术相比，优点在于：本发明产品结构简单、设计合理，使用本发明产品加工纸张，不但能够有效提高切纸速度，还能够根据要求切出符合规定长度的纸张，大大拓宽了该产品的适用范围。
附图说明
图1为本发明的结构示意图。
图2为本发明的剖面结构示意图。
具体实施方式
下面结合具体附图和实施例对本发明作进一步说明。
如图1、图2所示，包括筒体1、切刀2、丝杆3、蜗杆4、涡轮5、丝杆容纳腔6等。
如图1、图2所示，本发明一种四刀滚切装置，包括筒体1，所述筒体1上均布开设有四个切刀滑槽，每个所述切刀滑槽中均设置有一把切刀2，切刀2均可在各自对应的切刀滑槽中相对移动，即根据所要切纸的长度调节切刀2伸出筒体1的长度；所述切刀2沿长度方向两端分别连接一根丝杆3，丝杆3与切刀2之间的连接可以通过焊接方式连接或者其他可以将丝杆3与切刀2相互固定在一起的方式，以实现丝杆3可以带动切刀2作伸出或收缩运动；每根所述丝杆3均螺纹连接于一个涡轮5的内螺纹孔中，所述涡轮5与沿筒体1轴向布置的蜗杆4相配合，且涡轮5转动限位固定于筒体1内，即涡轮5在筒体1内只能够进行转动，而不能产生位置的移动，由于涡轮5内孔设有与丝杆3相配合的螺纹，故涡轮5的转动将自然带动丝杆3作伸出或收缩运动；沿筒体1径向同一直线上的两把切刀上的四根丝杆3相互平行、交错布置；每一把切刀2上与丝杆3连接涡轮5一端相对应处均开设有丝杆容纳腔6，当丝杆3完全收缩于丝杆容纳腔6中时，与所述丝杆3相连接的切刀2收缩于筒体1内，这就可以保证在切最小长度纸张或不需要切纸时，可以将切刀完全或不完全收拢于筒体1内。
本发明的工作原理如下：本发明产品能够切出的最短纸张的长度为筒体1周长的四分之一，要切出上述尺寸规格的纸张，只需将四把切刀2缩至最小位，即，切刀2的切削刃刚刚伸出筒体1即可。当需要切出的纸张的长度大于筒体1周长的四分之一时，可以调节四把切刀2以同等长度伸出筒体1；当需要切纸的长度超过四把切刀2全部伸出最大长度时，所能够切出的纸张的长度时，可以通过减少伸出筒体1的切刀2的数量来实现切纸长度相应扩大的目的，通常的做法是缩掉沿筒体1直径方向相对应的两把切刀2，使得切纸装置中只有两把切刀进行切纸作业。本发明产品能够切出的纸张的最大长度为，只用一把切刀进行切纸时实现的，即，将其中三把切刀全部或部分收缩于筒体1内，而只保留一把切刀伸出筒体1，且将该切刀全部伸出筒体1即可。
在工作时，配合本发明四刀滚切装置还相对应配合设置有一个下辊，该下辊圆周面上均布设置有四个滑块，四个滑块起到刀垫的作用，该滑块与四刀滚切装置相配合进行工作；工作过程中，相应不工作的滑块可略低于工作刀口，也就是说，不工作的切刀(滑块)不必全部缩到底。
