Description

一种精确圆心对准切割的竹胚筒制条机 技术领域
本发明涉及竹制品加工领域，特别涉及一种精确圆心对准切割的竹胚筒制条机。
背景技术
毛竹制品因具有造型丰富、纹理优美和自然环保等众多优点，受到越来越多家庭的采用，毛竹加工是资源增殖型产业，不会因产业发展破坏环境，实现可持续利用，满足经济、生态协调发展的双重需要。毛竹必须加工成条状材料才能制作毛竹制品，现有技术大多采用人工与刀具配合的方法，经过多道工序和较长时间才能将毛竹加工成条状材料；当然也有自动化的毛竹分割制条机，其大多采用顶压机向破竹器逐根输送毛竹，破竹器大多采用围成一个圆状的多个切割刀，毛竹强行通过破竹器从而被切割成条，这其中存在的问题是，毛竹因是自然生长物，其本身并不是一个规则的管状体，毛竹的直径各不相同，并且毛竹各个节间的部分也不相同，因此在切割过程中，无法保证毛竹的圆心与多个切割刀的中心处保持在同一直线上，当毛竹的圆心与多个切割刀的圆心点不在同一直线上时，就会造成在切割时，位于越高处部分的毛竹段，其截面的弧越长，即造成了制成的各个毛竹条的弧长各不相同，因此在后续的制造工艺中，将毛竹条制成规则体，比如说块状体，就需要对其进行切割，而毛竹条的弧长差异太大，就会产生太多的废料，进而就会大大的增加厂家的生产成本。

具体实施方式
下面结合说明书附图和实施例，对本发明的具体实施例做进一步详细描述：
参照图1至图7的一种精确圆心对准切割的竹胚筒制条机，包括控制柜1， 控制柜1的旁侧设有旋转料盘2，控制柜1上安装有传送带3和破竹装置4，传送带3连接在旋转料盘2和破竹装置4之间，破竹装置4设有竖直放置的料管5，料管5内部下方安装有锥形的刀架5a，刀架5a的外壁上安装有若干沿周向分布的刀片5a1，破竹装置4还包括设于料管5上方的双行程液压缸4a，双行程液压缸4a的活塞杆顶端安装有压块4a1，压块4a1通过双行程液压缸4a驱动能够伸入料管5内部。
本发明针对经切割后形成的竹胚筒6的制条，其原理是通过旋转料盘2将竹胚筒6整齐有序的以立式的姿态送入传送带3上，而后通过传送带3上的推料气缸3a将竹胚筒6推入破竹装置4上，竹胚筒6在进入破竹装置4上后，掉落至料管5内并套在刀架5a的上部，因刀架5a的形状为锥形，竹胚筒6在套在刀架5a上后能够自动使自身的圆心与刀架5a的圆心对准，而后由双行程液压缸4a驱动压块4a1下压，使竹胚筒6强行通过刀架5a，通过刀架5a上沿周向分布的多个刀片5a1将竹胚筒6切割成等弧长的多个条状材料。
传送带3的两侧以及其末端均设有挡料板，两侧的挡料板用于防止竹胚筒6在传送带3上运输时向两侧倾倒，末端的挡料板用于阻止竹胚筒6继续前进；挡料板的高度略低于竹胚筒6的高度，传送带3的末端料位一侧安装有推料气缸3a，推料气缸3a的推送方向垂直于所述传送带3的输送方向，推料气缸3a用于将传送带3末端料位上的竹胚筒6推送至破竹装置4上，对应的所述破竹装置4设于传送带3旁侧并且与推料气缸3a对立设置。
所述推料气缸3a为三杆气缸，推料气缸3a的三个输出杆端部安装有料托3a1，料托3a1的高度略低于竹胚筒6的高度，采用三杆气缸更有利于对这种高度的料托3a1进行固定，料托3a1的前侧设有弧形面，弧形面的设计用于扩大料托3a1和竹胚筒6的接触面积，并对竹胚筒6形成包裹，防止推送时，竹胚 筒6向两侧偏移。
破竹装置4还包括第一平板4b，第一平板4b的上端面与传送带3的承载面处于同一平面，第一平板4b上开设有圆孔4b1，圆孔4b1的位置对应所述推料气缸3a行程末端的位置，料管5安装在第一平板4b的下方并且料管5与圆孔4b1同轴设置，推料气缸3a能够将传送带3末端料位上的竹胚筒6推送至第一平板4b的圆孔4b1上方位置，竹胚筒6通过自身重力穿过圆孔4b1下落至料管5内；第一平板4b上还设有由两个立板构成的料道，推料气缸3a在推料时，竹胚筒6自该料道内经过，以防止竹胚筒6倾倒。
第一平板4b上设有安装支架4c，安装支架4c的顶部悬置在圆孔4b1的上方，所述双行程液压缸4a固定在所述安装支架4c的顶部上方，所述压块4a1设于所述安装支架4c的顶部下方，双行程液压缸4a的活塞杆穿过安装支架4c的顶部与压块4a1连接；双行程液压缸4a的第一行程距离对应安装支架4c顶部与第一平板4b之间的距离，其第二行程距离对应第一平板4b与刀架5a顶部之间的距离；通过该安装支架4c将双行程液压缸4a架高，双行程液压缸4a在完全回缩时，不会对竹胚筒6的上料构成阻挡，竹胚筒6进入料管5内后，双行程液压缸4a首先驱动压块4a1快速移动至接近第一平板4b的位置，而后双行程液压缸4a的输出力增大，速度变缓，将竹胚筒6缓慢而又有力的下压，对竹胚筒6进而切割。
破竹装置4还包括第二平板4d，所述料管5设于第一平板4b和第二平板4d之间，第一平板4b和第二平板4d之间还设有围绕所述料管5设置的四个第一支撑杆4e；料管5的上端和下端均设有法兰盘5b，料管5通过两端的法兰盘5b并配合螺栓紧固在第一平板4b和第二平板4d之间。
所述料管5的内部底端设有刀架托5c，刀架托5c包括圆柱体5c1以及围绕 所述圆柱体5c1设置的若干连接片5c2，连接片5c2一端焊接在圆柱体5c1上，连接片5c2另一端通过焊接方式与料管5的内壁固定连接，刀架5a放置在所述圆柱体5c1上方并通过螺栓将圆柱体5c1与刀架5a的底部连接，刀架5a上每个刀片5a1所处的位置均位于一个连接片5c2的正上方；所述第二平板4d悬置在所述控制柜1的上方，在第二平板4d与控制柜1之间设有四个呈矩阵分布的第二支撑杆4f，第二平板4d上开设有与料管5同轴设置的落料孔4d1；所述第二平板4d下方设有滑道4g，滑道4g自落料孔4d1正下方处向控制柜1外侧倾斜向下延伸。竹胚筒6切割后形成的条状材料自连接片5c2与连接片5c2之间的空隙处通过，并在通过落料孔4d1后，掉落至滑道4g上，通过滑道4g导出控制柜1外。
以上所述，仅是本发明的较佳实施例而已，并非对本发明的技术范围作出任何限制，故凡是依据本发明的技术实质对以上实施例所作的任何细微修改、等同变化与修饰，均仍属于本发明的技术方案的范围内。
