Description

一种模压成型的组合烟花
技术领域
本发明涉及一种娱乐烟火产品， 尤其是一种组合烟花。
背景技术
按照中华人民共和国国家标准 GB10631-2004《烟花爆竹 安全与质量》和 GB19593-2004 《烟花爆竹 组合烟花》 等规范性文件的定义， 组合烟花是由多个单筒组合而成的烟花产品。 一个单筒称为一发。 传统组合烟花由多个纸质筒管组装而成， 存在工序繁多、 生产效率低、 产品的规范性或标准性不高等等弊端。
近年来我公司开发了一种整体一次性成型的组合烟花， 将浆料通过模压成型。 其成型体 的形状及结构与传统组合烟花类似， 成型体的本体的整体外观形状一般为圆角棱柱体或圆柱 体等。 本体上平行均匀分布若干管状腔体， 管状腔体的结构和作用与传统组合烟花的单筒类 似， 管状腔体上端口开放， 下端口封闭， 管状腔体内置发射烟火药物以及效果件。 但其传火 模式与传统组合烟花的侧部传火连引结构不同， 采用底部传火连引结构。 管状腔体的封闭端 开设贯穿本体底面的传火孔， 底面设有连接传火孔底面开口的布线凹槽以保护定位引线， 引 线嵌入布线凹槽内连接各传火孔， 通过传火孔引燃上述发射烟火药物。 其制作工艺参见中国 专利文献， 授权公告号 CN 101377395B, 授权公告日 2012年 4月 11 日， 名称为 "模压成型 的花炮外筒、 礼花弹球壳及其制作"。
但是， 我们在实践中发现， 这种整体一次性成型的组合烟花仍然存在一些弊端， 特别是 容易出现串火现象： 即各个管状腔体内的火药和效果件不是依照设计燃放程序由引火线依序 点燃发射， 而是出现两个或多个管状腔几乎同时发射的情况， 完全破坏了燃放效果。
发明内容
为了解决上述弊端， 本发明所要解决的技术问题是， 提供一种模压成型的组合烟花， 能 够有效杜绝串火现象的发生， 从而保障设计燃放效果的顺利实现。 为了解决上述技术问题， 本发明采用的技术方案是， 一种模压成型的组合烟花， 包括在本体上平行均匀分布的若干管 状腔体， 管状腔体上端口开放， 下端口封闭， 管状腔体内置发射烟火药物以及效果件， 管状 腔体的封闭端开设贯穿本体底面的传火孔， 传火孔的底面开口位于布线凹槽内； 在所述布线 凹槽内、 传火孔底面开口之间设有截断凹槽； 所述布线凹槽用胶水密封。
经过我们的研究， 串火现象的发生是基于下述原因， 引线嵌入布线凹槽后， 引线与布线 凹槽的侧壁和底面之间存在间隙， 在一段布线凹槽中连续存在的间隙会导致该间隙内的传火 孔之间发生串火的现象， 由于燃烧的高压火药气体沿布线凹槽前进的速度快于引线燃烧的速 度， 火药气体沿间隙窜入传火孔内， 使得管状腔体内的发射火药和效果件被火药气体无序点 燃。
采用胶水密封布线凹槽， 可以减少串火现象的发生。 胶水可采用各花炮原材料市场的市 售产品， 如防潮胶等。 为了提高其防火截断性能， 并使其具有较好流动分布性和粘接性能。 优选地， 所述胶水的组份为： 按重量份数比， 防潮胶 1-2份， 双飞粉 2-4份。 按一般方法混 合均匀即可。 但是由于胶水分布很难与间隙完全吻合， 该间隙仍然可能存在， 特别是引线与布线凹槽 的底面之间的间隙。 故而在布线凹槽内再设置一个相对布线凹槽更深的截断凹槽， 并设置在 传火孔底面开口之间， 使得胶水很容易地在布线凹槽内， 沿引线截面方向形成闭合的环形， 截断火药气体沿间隙前进的通道， 杜绝串火现象的发生。 同时阻断了燃烧的高压火药气体从 引火孔冲出造成事故的各种路径， 约束了所有管状腔体内的火药气体只能向上从管状腔体上 端开口冲出， 有效避免发射能量损耗， 保证产品安全的同时， 规范了火药用量， 提高了燃放 质量。
从以上分析可以看出， 所述截断凹槽可以整体 （如沿布线凹槽内腔壁的截面 U型设置） 或部分 （如沿布线凹槽内腔壁的截面的某个部分设置） 设置， 截断凹槽的长度或宽度、 深度 的设置可根据实际情况调整。 然而， 综合了截断性能和制造工艺的要求， 优选地， 所述截断 凹槽设置于布线凹槽的内腔底面。 优选地， 所述截断凹槽的宽度大于所述布线凹槽的宽度。 优选地， 所述截断凹槽为矩形盲孔。
优选地， 所述管状腔体的封闭端开设一个贯穿本体底面的传火孔， 所述布线凹槽是一条 连续性的整体式凹槽， 各传火孔的底面开口都位于整体式凹槽内， 所述截断凹槽设置在各个 底面开口之间。 使用中， 只需将一根完整的引线嵌入所述布线凹槽中， 即可满足传火要求， 每个传火孔无需单独***引线， 引线在布线凹槽内燃烧产生的燃烧气体火花从传火孔中进入 管状腔体内， 点燃发射火药和效果件。
由于某些产品本体底部比较厚， 使得传火孔轴向方向较长， 引线点燃后传火火花高度不 够， 无法通过传火孔接触发射药， 导致管状腔内发射火药无法点燃从而严重影响产品燃放效 果， 为了避免上述情况， 作为一种优选， 所述传火孔为锥形孔， 以所述本体底面方向为锥顶， 以所述管状腔体内底部方向为锥底。 使发射火药沿漏斗状的锥形孔下落， 与引线更加接近， 使引线点燃后的火花充分接触到发射火药， 保证不会有点不燃的现象。
优选地， 所述连续性的整体式凹槽的转角处设为圆弧转角。 减小了引线在转角处的折叠 程度， 防止了引线对折过程中磨损或折断现象的出现， 避免了因引线断裂导致的产品质量问 题。
优选地， 所述管状腔体的封闭端开设两个贯穿本体底面的传火孔， 一个为传火进孔， 另 一个为传火出孔， 所述布线凹槽是多条相互间断的分散式凹槽， 所述传火孔中， 除了连接点 火引线的一个传火进孔和连接备用点火引线的一个传火出孔以外， 一个管状腔体的传火进孔 和相邻的另一个管状腔体的传火出孔的底面开口位于同一条分散式凹槽内， 所述截断凹槽设 置在所述两底面开口之间。 使用中， 根据分散式凹槽的条数准备多段引线， 将每一段引线的 两端分别***槽内的传火进孔和传火出孔即可。
优选地， 所述本体底面四周设有凸台围成的边框， 边框上设有通风泄压槽。 凸台围成的 边框使得组合烟花本体底面抬离地面， 防潮防损， 同时通风泄压槽一方面使得底面通风加快 产品干燥； 另一方面在烟花底面万一出现火药气体漏出时， 气体压力能够及时得到释放， 避 免组合烟花倾倒造成更大的事故。
下面将结合附图和具体实施方式对本发明做进一步说明。

本例中， 每个管状腔体 2开设一个传火孔 5， 参见图 2， 所述布线凹槽 7是一条连续性的 整体式凹槽， 其转角处 11设为圆弧转角。 88个传火孔 5的底面开口 6都位于布线凹槽 7内， 所述截断凹槽 8设置在各个底面开口 6之间。使用中， 只需将一根完整的引线 10嵌入所述布 线凹槽 7中。 引线 10两端通过本体 1的侧面布线凹槽 14引出至本体 1顶面， 分别作为点火 引线和备用点火引线。 所述传火孔 5为锥形孔， 以所述本体 1底面方向为锥顶， 以所述管状 腔体 2内底部方向为锥底。
可以看出， 截断凹槽 8设置在两个传火孔 5的底面开口 6之间， 使得胶水 9很容易地在 布线凹槽 7内， 沿引线 10截面方向形成闭合的环形， 截断火药气体沿间隙前进的通道。 实施例 2 : 参见图 4-6， 反映本发明的另一种具体结构， 为采用整体一次性模压成型工艺制作 的 25发组合烟花。 同样， 所述模压成型的组合烟花包括在本体 101上平行均匀分布的 25个 管状腔体 102， 管状腔体 102的上端口开放， 下端口封闭， 管状腔体 102内置发射烟火药物 以及效果件， 管状腔体 102的封闭端开设贯穿本体 101的底面的传火孔 105， 传火孔 105的 底面开口位于布线凹槽 103内； 在所述布线凹槽 103内、 传火孔 105的底面开口之间、 设有 截断凹槽 104; 所述布线凹槽 104装置引线 106后， 用胶水密封。 所述截断凹槽 104设置于 布线凹槽 103的内腔底面。 所述截断凹槽 104为矩形盲孔。 所述本体 101的底面的四周设有 凸台围成的边框 107， 边框 107上设有四个通风泄压槽 108。
其不同之处在于， 本例中， 每个管状腔体 102开设两个传火孔 105， 一个为传火进孔， 另一个为传火出孔， 布线凹槽 104是 24条相互间断的分散式凹槽， 从图 4可以看出， 共有 50个传火孔 105， 除了连接点火引线的一个传火进孔 109和连接备用点火引线的一个传火出 孔 110以外， 其余 48个按照一进一出的方式两两组合成 24组， 即一个管状腔体 102的传火 进孔和相邻的另一个管状腔体 102的传火出孔两两组合， 每个组合中传火孔 105的两底面开 口都位于同一条布线凹槽 103内， 所述截断凹槽 104设置在所述两底面开口之间。 使用中， 根据分散式凹槽的条数准备多段引线 106， 将每一段引线 106的两端分别***槽内的传火进 孔和传火出孔即可， 点燃后的传火路线依序是点火引线一传火进孔 109 传火进孔 109所在 的管状腔体内的发射火药一传火进孔 109所在的管状腔体的传火出孔一相邻管状腔体的传火 进孔一相邻管状腔体内的发射火药一相邻管状腔体的传火出孔一如此依序传火直至传火出孔 110以及备用点火引线。 采用备用引线点火时顺序相反。
可以看出， 截断凹槽 104设置在两个传火孔 105的底面开口之间， 使得胶水很容易地在 布线凹槽 103内， 沿引线 106截面方向形成闭合的环形， 截断火药气体沿间隙前进的通道。 实施例 3: 参见图 7、 8， 与实例 2不同之处在于， 本例为采用整体一次性模压成型工艺制作 的 19发组合烟花， 本体 201形状呈正六边形。截断槽 202的设置同样能够使得胶水很容易地 在布线凹槽 203内， 沿引线截面方向形成闭合的环形， 截断火药气体沿间隙前进的通道。 实施例 4: 参见图 9， 同样为采用整体一次性模压成型工艺制作的 25发组合烟花。 与实施例 2不同之处在于， 其有一个管状腔体开设 3个传火孔， 有一个管状腔体只开设了 1个传火孔， 形成的传火顺序不同以满足燃放流程设计的要求， 达到特殊的 "齐发"效果。 但是同样在布 线凹槽内设置截断槽， 使得胶水很容易地在布线凹槽内沿引线截面方向形成闭合的环形， 截 断火药气体沿间隙前进的通道。
本发明描述的上述实施方式仅是为了清楚地说明本发明的技术方案， 而不能理解为对本 发明做出任何的限制。 本发明具有公知的多种替代方式和变形， 如本体形状、 传火方式的设 置或者布线凹槽分布方式等， 在不脱离本发明实质意义的前提下， 均落入本发明的保护范围。
