Description

一种自磨刀滤棒成型分切机构 技术领域
本发明属于滤棒成型设备技术领域，具体地说，涉及一种自磨刀滤棒成型分切机构。
背景技术
滤棒成型机生产出的滤棒需要分切成段，在分切过程中，需要来回的退刀与进刀来实现滤棒的分切。同时，分切机构在退刀与进刀过程中，不易配置磨刀装置，切刀在出现钝刀时不能及时得到处理。虽然，一些分切机构上设置有在切刀退刀对切刀进行磨刀的装置，但这种结构通常要考虑磨刀装置不能影响切刀的进刀与退刀，结构相对较复杂。并且磨刀工作开始后，切刀仅受磨刀砂轮单一方向的打磨，切刀刃口易出现“卷刃”现象，导致切割的滤棒出现“切口不平、切口毛茬”等质量问题。此外，由于磨刀砂轮连续不断的磨刀，切刀磨损较快，切刀进刀周期较短，磨刀过程中会产生大量的金属粉末，若不能够及时的打磨，金属粉末会附着在切刀上，从而被切刀带到滤棒切口端面形成“黑点”，存在极大的质量隐患。
发明内容
为了克服背景技术中存在的问题，本发明提出了一种自磨刀滤棒成型分切机构；能够实现在不来回移动切刀的情况下实现对滤棒的分切，同时，切刀的磨刀质量得到提高，确保切割刀片锋利的同时，延长切刀使用寿命，提升滤棒端面外观质量。

进一步，所述的上磨刀装置10与下磨刀装置11结构一致，包括安装架15、调节架16、磨刀电机17、磨刀砂轮18，所述的调节架16安装在安装架15上，磨刀电机17安装在调节架16上，磨刀砂轮18安装在磨刀电机17的驱动轴上。
进一步，所述的调节架16包括调节臂19、万向头20、连接架21、锁紧螺栓Ⅰ22、锁紧螺栓Ⅱ23，所述的调节臂19固定安装在安装架15上，调节臂19的端部安装有万向头20，磨刀电机17固定安装在连接架21上，连接架21设置有一个球形凹槽，万向头20的球形端安装在球形凹槽内，球形凹槽的壁上设置有夹角不同用于锁紧万向头20的锁紧螺栓Ⅰ22、锁紧螺栓Ⅱ23。

本发明的有益效果：
本发明能够实现在不来回移动切刀的情况下实现对滤棒的分切，同时，本 发明能够使切刀在切割滤棒过程中，通过上磨刀装置与下磨刀装置不断修正切刀刃口，使切刀始终保持锋利状态，有效提升滤棒切口外观质量。

具体实施方式
下面将结合本发明实施例和附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
如图1-3所示，一种自磨刀滤棒成型分切机构包括滤棒条导向管1、导向管套2、切烟管3、切烟管支架4、牵手5、偏心轮6、支撑座7、刀头8、切刀9、上磨刀装置10、下磨刀装置11、刀轴12、电机13、驱动机构14。所述的电机13与刀轴12连接，刀头8安装在刀轴12上，切刀9安装在刀头8上，刀头8的一侧安装有支撑座7，支撑座7的顶板上开设有一个一端大一端小滑槽，牵手5的上端设置有切烟管支架4，切烟管支架4安装在支撑座7顶板上的滑槽内，切烟管3安装在切烟管支架4上，切烟管3上开设有一个能够让切刀9穿过的刀槽，刀槽的两侧壁上开设有正对的通孔，通孔的上部开设有贯穿切烟管3两侧壁上部的开口，所述的滤棒条导向管1的出料端安装有一个导向管套2，导向管套2 的出口正对刀槽的两侧壁上的通孔，牵手5的下端安装在偏心轮6上，偏心轮6固定安装在驱动机构14上。生产加工的好的滤棒条从传入到到滤棒条导向管1中，从滤棒条导向管1端部的导向管套2导出进入到切烟管3上的通孔中。启动电机13，由电机13通过刀轴12带动刀头8转动，而刀头8则带动安装在其上的切刀9跟随其一起转动。启动驱动机构14，由驱动机构14带动偏心轮6转动，由于与偏心轮6连接的牵手5的上端设置有位于支撑座7的顶板上开设有一个一端大一端小滑槽内的切烟管支架4，切烟管支架4为一个弹片构成的开口向左的U型结构，而切烟管3安装在U型结构的两侧内壁上，当偏心轮6带动牵手5工作时，牵手5相当于一根连杆，在偏心轮6的转动过程中，由于支撑座7的顶板上滑槽的限位作用，使切烟管3沿滑槽作用移动；由于支撑座7的顶板上的滑槽一端大一端小，滑槽靠近偏心轮6一端开口大，远离偏心轮6一端开口小，这样，当牵手5带动切烟管3向右运动(靠近偏心轮6一侧)运动时，切烟管支架4的U型结构开口张大，从而使得切烟管3上通孔及开口逐渐张开，而滤棒条导向管1内的滤棒条向左移动；当偏心轮6转到通过牵手5带动切烟管支架4向左运动过程中，切烟管支架4的U型结构开口逐渐闭小，从而使得切烟管3上通孔及开口逐渐合并，实现对滤棒条的夹紧。与此同时，当切烟管支架4到达滑槽的最右端时，电机13正好带动刀头8上的切刀9到达切烟管3上的刀槽内，实现对滤棒的分切。这个分切过程中，电机13一致带动刀头8转动，刀头8上未安装切刀9的位置在转动过程中不影响滤棒条的进料，从而实现了滤棒条在尽量过程中，采用旋转进刀与退刀，不需要采用垂直滤棒条的进刀机构来实现进刀与退刀。
刀头8的上侧与下侧分别安装有对切刀9两面进行打磨的上磨刀装置10、下磨刀装置11。由于本发明采用旋转实现切刀的进刀与退刀，这样在刀头8的 上侧与下侧分别安装上磨刀装置10、下磨刀装置11即可实现对切刀9刀刃的打磨，不断修正切刀刃口，使切刀始终保持锋利状态，降低切刀磨损量，避免切刀磨损过快产生金属粉末附着在滤棒端面形成“黑点”质量隐患，有效提升滤棒切口外观质量；同时降低了切割刀片的消耗，节约了成本。
所述的上磨刀装置10与下磨刀装置11结构一致，包括安装架15、调节架16、磨刀电机17、磨刀砂轮18，所述的调节架16安装在安装架15上，磨刀电机17安装在调节架16上，磨刀砂轮18安装在磨刀电机17的驱动轴上。所述的调节架16包括调节臂19、万向头20、连接架21、锁紧螺栓Ⅰ22、锁紧螺栓Ⅱ23，所述的调节臂19固定安装在安装架15上，调节臂19的端部安装有万向头20，磨刀电机17固定安装在连接架21上，连接架21设置有一个球形凹槽，万向头20的球形端安装在球形凹槽内，球形凹槽的壁上设置有夹角不同用于锁紧万向头20的锁紧螺栓Ⅰ22、锁紧螺栓Ⅱ23。通过采用与万向头20匹配的连接架21实现对磨刀电机17的安装，能够实现对磨刀电机17角度的调整，从而实现对磨刀电机17上磨刀砂轮18对切刀9刀刃打磨角度的调整，保证磨刀砂轮18能够对切刀9的刀刃进行有效打磨，磨刀砂轮18的调整完毕后，通过具有一定角度的锁紧锁紧螺栓Ⅰ22、锁紧螺栓Ⅱ23同时抱紧万向头20，使连接架21固定在万向头20上，避免磨刀砂轮18在打磨切刀9的过程中出现晃动，影响切刀9的打磨效果。
在本发明中，如图4所示，所述的上磨刀装置10与下磨刀装置11的磨刀电机17分别通过与控制器Ⅰ、控制器Ⅱ连接，控制器Ⅰ、控制器Ⅱ分别通过继电器与PLC控制系统24连接，电机13通过进刀电磁阀与PLC控制系统24连接。刀头8上配置两把切刀9，两把切刀9对称安装在刀头8的弧形表面上，上磨刀装置10、下磨刀装置11的磨刀电机17分别带动安装在其上的磨刀砂轮18对切 刀9进行打磨(在此将上磨刀装置10、下磨刀装置11的磨刀电机17、磨刀砂轮18分别叫做上磨刀电机、下磨刀电机与上磨刀砂轮、下磨刀砂轮)，刀头8每转动一圈，切刀9分别被上磨刀砂轮、下磨刀砂轮打磨两次，刀头8连续不断运转。通过改变上磨刀电机、下磨刀电机的工作方式，设备启动后，上磨刀电机、下磨刀电机先以正转方式工作时间T1后，上磨刀电机、下磨刀电机停止工作时间t1，然后上磨刀电机、下磨刀电机再次启动以反转方式工作时间T2，反转完成后，上磨刀电机、下磨刀电机再次停止工作时间t2，然后上磨刀电机、下磨刀电机再次启动以正转方式工作时间T1，完成一个工作循环。上磨刀电机、下磨刀电机正转工作时间T1与上磨刀电机、下磨刀电机反转工作时间T2相等上磨刀电机、下磨刀电机正转间歇时间t1与上磨刀电机、下磨刀电机反转间歇时间t2相等；上磨刀电机、下磨刀电机正转及反转控制顺序如图5所示。上磨刀电机、下磨刀电机通过正转与反转交替的工作方式对切刀进行打磨，使切刀9的刃口因单一方向磨刀产生的“卷刃”现象被及时修正，避免滤棒端面出现“切口不平、毛茬”等质量问题。此外，上磨刀电机、下磨刀电机在正转和反转后均停止一段时间，可在保证切刀锋利的状态下，减缓切刀9的磨损速度，消除了因切刀磨损过快产生大量金属粉末附着在滤棒端面上形成“黑点”的质量隐患，极大提升滤棒产品外观质量。
实用本发明，在满足滤棒切割端面外观质量指标前提下，可延长成型机设备刀片的使用寿命约400-500％。
最后说明的是，以上优选实施例仅用以说明本发明的技术方案而非限制，尽管通过上述优选实施例已经对本发明进行了详细的描述，但本领域技术人员应当理解，可以在形式上和细节上对其作出各种各样的改变，而不偏离本发明权利要求书所限定的范围。
