Description

一种环形拉带及其制作方法 技术领域
本发明涉及充气产品技术领域，尤其是指一种用于充气产品的环形拉带及其制作方法。
背景技术
由于充气产品兼具携带方便、便于收纳和舒适性的特点，其使用越来越广泛。现有的充气产品包括充气床垫、充气沙发、充气水池等等。而这些充气产品要实现预定的形状，必须依靠其内部的结构而实现。如现有的充气床有拉带式充气床，或叫波浪式、直条形、工字形；也有立柱式充气床，或叫蜂窝形、圆柱形，其名字来源于其内部构造。
如果充气产品内部没有设置拉带，充气床很有可能变成一个气球，为了保持充气床是一个长方体，就需要在里面用拉带或气柱将充气床上表面和下表面绷紧，并且床面要求越平整，其内部设置的拉带数量越多。
传统充气产品内部的拉带为满足产品的受力要求，均采用具有一定厚度的塑胶片膜，它们的材质为PVC、TPU膜，通过冲裁及高频机焊接封口形成筒状拉带或环形拉带，用于连接充气床垫的上下层。
该环形拉带的缺点在于：1、塑胶片材受力有限，充气产品内部气压会令塑料片膜产生拉伸变形，从而影响充气产品使用寿命；2、由于环形拉带由整片塑胶片膜构成，无形中增加了整个充气产品的重量，即材料用料多，导致材料及包装和运输的成本增加，且该环形拉带成品的一切制作费(冲裁、封口等)较大，导致其生产成本较高。
发明内容
本发明的目的在于提供一种用于充气产品的环形拉带及其制作方法，该环形拉带能承受更大的拉力强度，且不易抽丝变形，能有效地延长充气产品的使 用寿命。
为达成上述目的，本发明的技术方案为：一种环形拉带，包括一根不间断的线体和塑胶片膜，所述线体沿一轴向螺旋式绕织形成线环，所述塑胶片膜平行线体绕轴方向设置在线环内，并与所述线环的上、下线体固定形成上、下拉带固定面，所述线环的左、右线体形成左、右拉带拉伸面。
进一步，所述拉带固定面是由所述塑胶片膜对夹线环的上、下线体固定而成。
进一步，所述塑胶片膜与线环是通过高频或超声波焊接固定，或是通过胶液粘接固定。
进一步，所述上、下拉带固定面与左、右拉带拉伸面均为对称设置。
进一步，所述拉带拉伸面内的线体均匀分布且相互平行，或是呈V字形排布。
进一步，所述拉带拉伸面的拉伸长度与充气腔的高度或宽度相同。
进一步，所述线体为尼龙或捻纱或涤纶丝线材质。
进一步，所述塑胶片膜为PVC或TPU或PE或PU材质。
进一步，所述环形拉带通过所述拉带固定面固定在充气产品内部的充气腔内壁上。
一种环形拉带的制作方法，其具体步骤为：
步骤1，将一根不间断的线体在工装模具上沿轴向螺旋式绕织形成一线环；
步骤2，在工装模具的前方或上方设置热熔焊固设备或粘胶机，取大小与线环固定所需宽度相适配的塑胶片膜在线环内侧，平行线体绕轴方向置于热熔焊设备或粘胶机的下模上；
步骤3，将熔接上模下压将塑胶片膜与线环固定连接在一起，分别与线环的上、下线体固定形成上、下拉带固定面；
步骤4，将固定了塑胶片膜的线环在绕轴模具上分割后，便制成了具有耐拉伸强度的环形拉带。
进一步，所述步骤3与步骤4中增设再加设一工序是：再通过热熔焊固设 备或粘胶机将塑胶片膜在线环外侧平行线体绕轴方向，与步骤3中的上、下拉带固定面固定在一起，即线环的上下线体由两片塑胶片膜对夹固定。
采用上述方案后，本发明的增益效果在于：与现有技术相比，本发明由一根不间断的线体沿轴向螺旋式绕织而成，该环形拉带具有较高的拉伸强度，承受力更强，与现有技术的直线式拉带或片膜拉带相比，产品在使用时该环形拉带不容易脱线，能够有效的延长充气产品的使用寿命，且重量轻、生产成本更低。
本发明的环形拉带可适用于所有内部结构呈阵列点或线排布的充气产品，产品在充饱气体后，由于环形拉带的拉带拉伸面为对称结构，其拉力均衡，使得产品能保持美观，大幅度提升用户的产品体验感，且使用数次依然能保持原状，不变形。

具体实施方式
以下结合附图及具体实施了对本发明进行详细的说明。
一种环形拉带，如图1、2所示，包括一根不间断的线体11和塑胶片膜12，所述线体11沿一轴向螺旋式绕织形成线环，具体的，所述线体11为尼龙或捻纱或涤纶丝线材质，根据产品所需的大小可将线体11在模具上螺旋式绕织成任 意长、宽、高的线环，所述线环从穿模方向来看，其横截面呈口字形；
所述塑胶片膜12平行线体11绕轴方向设置在所述线环内，并与所述线环的上、下线体11固定形成上、下对称的拉带固定面，所述拉带固定面内的线体11在垂直于绕轴方向上平行排布，所述线环的左、右线体形成左、右对称的拉带拉伸面，该环形拉带1通过所述拉带固定面固定在充气产品内部的充气腔内壁上；具体的，所述拉带拉伸面的拉伸长度与充气腔的高度或宽度相同。
为使该环形拉带1能承受更多的拉力，如图3、4所示，本实施例中所述拉带拉伸面内的线体11均匀分布且相互平行，或者所述拉带拉伸面内的线体11与拉带固定面不是垂直状态，可呈V字形、呈三角形、T型或其他形状排布。
在本实施例中，所述拉带固定面是由所述塑胶片膜12对夹线环的上、下线体固定而成。具体的，当所述塑胶片膜12的数量为两片时，需将大小相同的两片塑胶片膜做增厚处理后，通过高频或超声波焊接或是通过胶液粘接，在线环内将塑胶片膜与线环的上、下线体固定在一起；当所述塑胶片膜12的数量为四片时，需将四片大小相等的塑胶片膜12分为两组，每组两片分别位于线环的内外侧，所述线环的上、下线体11夹入两片塑胶片膜12之间，通过高频或超声波焊接在一起或者通过胶液粘接固定形成拉带固定面；所述塑胶片膜12为PVC或TPU或PE或PU材质。
在本说明书及附图5-7中，所描述及所示出的充气产品为具有上述环形拉带的充气床垫2。当然，充气产品的类型不是限制性的。本发明能够涵盖充气沙发、沙发垫、充气水池、充气玩具等所有内部由阵列点状拉力构成的充气产品。
如图7所示，该充气床垫2包括：上片21、下片22和围片23，所述围片23的上、下边缘分别与上片21和下片22的四周边缘通过高频焊接形成密封式充气腔，上述环形拉带通过上、下拉带固定面热熔或粘胶固定在所述充气腔相对的两侧内壁上，用于连接上片21和下片22，如图6所示，即所述环形拉带根据产品情况可以设置在充气腔的上、下或前、后或左、右内壁上，使得环形拉带可以横纵分布在充气腔内，使该充气产品以保持使用者期望的形状，见图 5。
具体的，所述上片21、下片22上对应设有供上、下拉带固定面连接的熔接处，熔接处的数量和位置与所述环形拉带1的数量和位置相对应，如图7所示。本案中所述环形拉带1的拉伸长度与围片23的高度相同，并于充气腔内呈阵列排布，如图5所示，两者共同限定了充气产品的高度，使其形成一个较为平整的表面。当充气产品为圆形充气水池时，所述充气水池由上片、下片、内围片和外围片构成环状充气腔，所述环形拉带1的拉伸长度则与圆形充气水池的内围片和外围片间的距离相同。
一种环形拉带的制作方法，其具体步骤为：
步骤1，将一根不间断的线体11在工装模具上沿轴向螺旋式绕织形成一线环，所述线体11为连续的尼龙或捻纱或涤纶丝线材质；
步骤2，在工装模具的前方或上方设置热熔焊固设备或粘胶机，取大小与线环固定所需宽度相适配的塑胶片膜12在线环内侧，平行线体11绕轴方向置于热熔焊设备或粘胶机的下模上；
步骤3，将熔接上模下压将塑胶片膜12与线环固定连接在一起，分别与线环的上、下线体11固定形成上、下拉带固定面；
步骤4，将固定了塑胶片膜12的线环在绕轴模具上分割后，便制成了在垂直于线体绕轴方向的具有耐拉伸强度的环形拉带1，如图1所示。该环形拉带1在应用与各种充气产品时，只需依据充气产品内部的长度或宽度而截取相应长度拉带即可。
为进一步提高拉带固定面的强度，在塑胶片膜12与线环熔接固定时，是采用上下两片塑胶片膜12对夹而固定线环的上下箱体的方式，即塑胶片膜12为双层结构，如此形成的环形拉带，在实施于充气产品时，塑胶片膜12的厚度要求较小，因此线体11承担了拉伸强度，其延伸率小，强度佳，重量轻，大大减少了生产成本。
由于本发明的环形拉带是由一根连续不间断的线体在模具上螺旋式绕织而成的，且线环的上、下拉带由两片平行设置的塑胶片膜对夹固定形成拉带固定 面，因此，与现有技术相比，本发明的环形拉带在的左、右拉带拉伸面具有较佳的拉伸强度，不容易脱线，通过拉带固定面可以与充气产品的上、下胶层进行较佳的熔接，既满足了充气产品内部结构的牵引功能，又相对现有的拉片材料在重量上大大降低，节省了成本。
以上所述仅为本发明的较佳实施例，并非对本案设计的限制，凡依本案的设计关键所做的等同变化，均落入本案的保护范围。
