Description

棒垒球的结构、加工工艺及球衣的材质配方
技术领域
本发明属于一种球类运动器械，尤其涉及一种棒垒球。
背景技术
本专利的棒垒球指的是棒球或垒球。
现有的PU层球衣包裹的棒垒球，是以PU材质直接包裹于球芯外层，这种材质的回弹系数低易变形压扁难恢复，手感较滑爽没有牛皮的粘涩感影响抓握力在使用过程中打击后球衣与球芯易脱层，粘合性较差，且PU的化工味道上没有牛皮特有的味道，没有味觉效果，总体影响传统棒垒球特有的历史文化。
现有的传统棒垒球加工工艺是利用皮革吻合球芯尺寸设计刀模进行裁断再以手工缝合，受旺季影响，人工慢招工难培训成本高会造成产量低交期难以控制的现象。
发明内容
本发明提供一种棒垒球的结构，其目的是使棒垒球更加牢固。
本发明提供一种棒垒球的加工工艺，其目的是提高棒垒球的产量和品质稳定性。
本发明还提供一种棒垒球球衣的材质配方，其目的是使球芯与球衣的粘合性好，不易脱层，且在人体感觉上更具有牛皮球衣材质棒垒球的感觉。
本发明的目的还在于改善棒垒球的使用寿命、耐压力、耐击打次数、COR、弹跳系数。
本发明解决其技术问题所采用的技术方案是：
棒垒球的结构，包括球芯和球衣，其特征在于：球芯外包裹有纤维材质层，纤维材质层外包裹并粘合有球衣。
纤维材质层为一层以上的羊毛层及羊毛层外的一层或一层以上的TR线层。
所述粘合，可以是在纤维材质层与球衣之间以粘胶层粘合。
上述粘合形式时，棒垒球的加工工艺，是在球芯外缠绕纤维材质层，在纤维材质层外涂抹胶层，包裹上球衣后静置粘合。
所述粘合，还可以是在球衣内壁形成的硫化熔融层与纤维材质层粘合。
上述粘合形式时，棒垒球的加工工艺，是在球芯外缠绕纤维材质层，然后放入打胶后成型前的球衣材料中，再将球芯、球芯外的纤维材料层、纤维材料层外的球衣材料层一起放入模具中，经硫化工艺后，球衣材料层成型为球衣，并球衣内壁形成的硫化熔融层与纤维材质层粘合，将成品从模具中取出。
棒垒球的球衣的材质配方，其特征在于：至少包括橡胶和牛皮磨粉。
上述配方中还包括碳酸轻钙或碳酸重钙、软化油、硫磺等组成的橡胶硫化助剂。
本发明的有益之处在于：
本发明的方法制作的棒、垒球，在独立成型的球芯上增加了渗有橡胶的纤维材质层，使在球衣成型时，球衣与球芯之间贴合更牢固，而纤维材质中的多孔性结构具一定的吸气性，从而可很大避免球衣在成型中出现气泡而影响球体的品质和使用寿命。采用橡胶及牛皮粉碎料混合的配方材料进行包裹球芯制成的球衣，其味道和手感更近似牛皮效果，且橡胶独有的粘涩感和回弹力使产品在仿真技术上更加接近传统棒垒球且手感和功能性(回弹力、耐压力、耐打击数更佳)。总体在嗅觉、触觉、视觉上更具有高仿真棒垒球的效果。使用效果更佳。
具体实施方式
球芯可以选择现有技术球芯，或独立成型球芯：球芯可以是橡胶芯、PU芯、羊毛球芯等多种材质不同配方和工艺制成的。
球芯外缠绕纤维材质层，例如羊毛层、TR线层等，可以缠绕多层。
橡胶球衣的配方材料，为了使其更具牛皮仿真效果，从嗅觉上、手感和功能上更加优秀仿真，将牛皮材质粉碎后的牛皮磨粉参与配方中，可使球衣材质具有牛皮基因的味道，做为填充材料加入配方中，可减轻球衣重量及增加球衣的咬合力及硬度应力。球衣配方采用橡胶、牛皮磨粉、碳酸轻钙或重钙、硫磺、油、等橡胶助剂组成的配方(该配方依天气变化按要求进行用量比例、变换物料进行调整，以达到成型好、气泡少、耐黄变、抗老化等硬度弹跳度的标准要求)。
一种工艺是上述球衣材料经混炼打胶后，按球衣重量切料压片放进模具中经高温硫化成型。球衣圆周、重量以球芯圆周重量进行调整搭配，例如：成品重量要求，标准为145克±3克(即142-148克)，圆周要求8.75-9.25英寸之间，当球芯设定为120克时，则球衣应设定在25克±3克，圆周依此类推设定球衣的重量和圆周进行制作。温度与时间也随配方进行调整设定。
在球芯外的纤维材质层外抹上粘胶层，然后放置于两片或多片的已硫化成型的球衣中，静置粘合在一起整体融合成型。
上述工艺得到了球芯外包裹有纤维材质层，纤维材质层外包裹并以粘胶层粘合有球衣的棒垒球。
另一种工艺是，球芯和外面缠绕的纤维层直接放入混炼打胶后成型前的球衣材料内再一起放进模具中，经高温加热硫化后与球衣一起成型出模。
上述工艺得到了球芯外包裹有纤维材质层，纤维材质层外包裹有球衣，球衣内壁形成的硫化熔融层与纤维材质层粘合的棒垒球。
最后在球衣外以传统牛皮的棒垒球纹路配以喷漆上同等数量的缝线图案。
例如以现今研发成功的棒垒球球衣组合的羊毛球芯结构来示例，球芯的工艺为，采用34MM的橡胶小球芯(配方为橡胶、碳酸轻钙或重钙粉、硫磺等橡胶硫化助剂等十几种材料经过混炼打胶切料硫化而成)的特定圆周重量的小球芯。球芯成型后，再用粗细羊毛分层(常用里为粗羊毛+外为细羊毛，也可用三层细羊毛，分别分层卷绕在橡胶小球芯外面，以达到结实耐压、弹跳系数、COR、耐打击数、不易变形等成品功能达成的球芯功能要求)。羊毛线卷绕后还要再卷绕一层或多层的粗细有别的TR线(形成最外层，起与棒垒球球衣相调整圆周和重量的调节层，最终达成成品球的圆周重量标准要求，和球面的平整度)纤维材质多数要求耐高温、强拉力等线支捻度和含水率等品质要求。同时生产采用橡胶、牛皮材质粉碎后的牛皮磨粉、碳酸轻钙或重钙、硫磺、软化油等橡胶硫化助剂组成的配方混炼打胶。然后球芯和外面缠绕的羊毛层、TR线层直接放入混炼打胶后成型前的球衣材料内，再一起放进模具中，经高温加热硫化后与球衣一起成型出模。得到整个球体。最后在球衣外以传统牛皮的棒垒球纹路配以喷漆上同等数量的缝线图案。得到成品。
本发明传统棒垒球人工加工难和品质难控制等的综合缺点，采用橡胶材质以机器加工方式替代了原传统皮革材质以手工缝制球衣的缝合加工工艺和球衣材料，从而改变手工产量极低招工培训难的缺点，使产量提高和品质稳定。本技术以高产能的基础上更使产品功能等系数要求的品质更稳定，甚至提升了产品的功能品质和耐打击次数。另有针对PU材质球衣包裹的棒垒球，回弹系数低、易变形、化工成份味道重和手感不粘涩，仿真度低的缺陷，采用橡胶加牛皮粉碎料混合的配方，从而在球体使用时球芯与球衣的粘合咬合性较PU好且不易脱层，以及在嗅觉上、手感上和回弹等功能系数上更加高仿真和更具有棒垒球文化的基因存在。
采用本方法制作的棒垒球，在独立成型的球芯上增加了渗有橡胶的纤维材质层，使在球衣成型时，球衣与球芯之间贴合更牢固，而纤维材质层中多孔性结构具一定吸气性，从而很大避免球衣在成型中出现气泡而影响球体的品质和使用寿命，而没有添加渗有橡胶的纤维材质层，耐打击次数比渗有橡胶的纤维材质层较少。
