Description

一种复合管生产设备的内衬带上料机构 技术领域
本发明属于复合管道技术领域，涉及一种复合管生产设备的内衬带上料机构。
背景技术
由于现有的排水管等管道是采用塑料制成，其耐压性能较差，因此通常会采用复合管，新型复合管有些是采用玻璃纤维与方格布复合毡制成的内衬带进行复合，来制成复合管，这样子的复合管能满足高强度和高韧性的要求。目前，市场上也现了用于生产该类型复合管的设备，该设备通常具有用于将内衬带卷绕在设备芯轴上的上料机构。如中国专利文献公开的一种不停机连续生产玻璃纤维管类型材工艺方法及设备(申请号：201911075162.0)，该设备通过先将玻璃纤维纱穿过胶槽进行浸胶，然后抽出外毡层、芯毡层，使外毡层、芯毡层将浸渍有带胶树脂的玻璃纤维纱内外夹持，之后将毡纱复合物绕在成型模芯上，再经过固化模具制成复合管道。然而，现有设备的内衬带上料结构在将内衬带或者毡纱复合物卷绕在芯轴上时，往往存在卷绕之后内衬带张紧度太松或者太紧的情况，而且难以很好地保证内衬带的平整度，因此内衬带卷绕效果不好，导致制造的产品往往难以达到很高的质量。
发明内容
本发明的目的是针对现有的技术存在上述问题，提出了一种复合管生产设备的内衬带上料机构，本发明所要解决现有设备由于内衬带卷绕效果不好而导致产品质量不高的问题。
本发明的目的可通过下列技术方案来实现：一种复合管生产 设备的内衬带上料机构，包括支架和芯轴，其特征在于，所述支架上设有卷圆罩和位于卷圆罩的前上方的张紧杆一，所述张紧杆一水平设置且与芯轴相垂直，所述卷圆罩包括位于芯轴左右两侧且相对设置的两块侧板，两块侧板的后侧边之间连接有后侧面倾斜朝上的背板，所述背板位于芯轴的上方，背板的底边与两块侧板的底边相连形成开口倾斜朝下的端口，所述芯轴穿过该端口且端口的边沿与芯轴的外周壁之间形成供内衬带穿过的间隙。
在制造时，将由内衬带绕成的带卷水平悬挂于支架上，设备运转时，内衬带从带卷上被拉出，拉出之后绕过张紧杆一的前侧然后又后方折返，折返后内衬带的中部贴着背板的后侧面，而内衬带的两侧边分别贴着两块侧板，由于两块侧板向下延伸且其底边与背板的底边相连形成开口倾斜朝下的端口，且端口的边沿与芯轴的外周壁之间仅具有间隙，因此内衬带到达端口处时，背板上的内衬带包覆在芯轴的顶部，而两块侧板上的内衬带则向芯轴的底部包绕，最终形成形成圆筒状并卷绕在芯轴的外周壁上，之后的工序便可以在内衬带上缠绕增强纤维，制造形成复合管道。
显然，本上料机构通过卷圆罩的前上方设置张紧杆一，在内衬带持续上料的过程中，张紧杆一能始终撑着内衬带，不仅能保证内衬带平整度高，而且内衬带经过张紧杆一、卷圆罩以及端口的过程中，内衬带经过两次折返，使得内衬带始终保持一定的张紧度，进而保证了内衬带在芯轴上的卷绕效果，提升了产品质量。
在上述的复合管生产设备的内衬带上料机构中，所述背板具有一呈倒三角形的平板部，所述平板部的左右两侧边分别连接有过渡部，所述过渡部为凸面朝上设置的弧形板体，所述过渡部的宽度由上至下逐渐增大，两块侧板的后侧边均与同侧的过渡部连接。平板部是卷圆罩最先与内衬带接触的部位，因此，设置倒三角形的平板部之后，不仅能保证内衬带有较高的平整度，而且平板部的宽度由上至下逐渐减小，因此配合过渡部的作用便能很好 地引导内衬带的两侧边逐渐向两侧板处转移，从而使内衬带顺畅地卷绕为圆筒状。此过程中，由于过渡部为凸面朝上设置的弧形板体，使得内衬带的两侧边逐渐向两侧板转移的过程中，不仅移动顺畅，而且能始终保持一定的张紧度，避免出现褶皱，因此保证了产品具有较高的质量。
在上述的复合管生产设备的内衬带上料机构中，所述平板部的顶边与张紧杆一相平行，所述平板部的顶边上还具有朝前翻出的卷边。卷边的设计避免内衬带与锋利的边楞接触，从而对内衬带形成保护。
在上述的复合管生产设备的内衬带上料机构中，所述支架上还固连有呈圆筒状且套设在芯轴上的定型筒，所述定型筒的内径略大于芯轴的外径，所述定型筒位于卷圆罩的前侧且与卷圆罩相邻设置。这样的设计使得内衬带经过卷圆罩卷绕为圆筒状之后，能直接进入定型筒，此时定型筒进一步对内衬带的形状进行保持和定型，从而提升内衬带在芯轴上的卷绕效果并提升产品的质量。
在上述的复合管生产设备的内衬带上料机构中，所述芯轴的下方设有能进行自转的支撑轴，所述支撑轴与芯轴相垂直，所述支撑轴位于定型筒的后侧且位于端口的前侧，所述支撑轴与芯轴之间具有间隙且内衬带穿过该间隙时能被支撑轴和芯轴夹紧。内衬带卷绕在芯轴上之后，内衬带的两侧边均位于芯轴的底部而没有相固连，在此处设置支撑轴之后，能对位于芯轴底部的内衬带的两侧边夹紧，以使内衬带保持圆筒状进入定型筒内，提升内衬带在芯轴上的卷绕效果。由于内衬带是持续向前移动的，因此支撑轴的自转能使内衬带能顺畅的移动。
在上述的复合管生产设备的内衬带上料机构中，所述支架上设有用于调节支撑轴高度位置的调节结构。通过该结构使得支撑轴与芯轴之间的间隙能进行调节，避免夹紧内衬带太紧或者太松。
在上述的复合管生产设备的内衬带上料机构中，所述支架上 固连有位于芯轴上方的安装杆，所述安装杆与芯轴相垂直，两块侧板的前侧边以及定型筒的顶面均固连在所述安装杆上。这样的设计便于卷圆罩和定型筒的安装，而且定型筒无需与芯轴固连，使得定型筒相对于芯轴悬空，进而实现内衬带从定型筒和芯轴之间的间隙通过。
在上述的复合管生产设备的内衬带上料机构中，卷圆罩的后上方还设有张紧杆二，所述张紧杆二的设置位置高于张紧杆一，所述支架上位于张紧杆一的后侧设有浸胶池，所述浸胶池的设置位置低于张紧杆一。这样的设计使得内衬带在移动过程中经过了多次变向，使得内衬带始终能保持合适的张紧度向前移动，进而使内衬带平整度高，制造得到的产品质量好。
在上述的复合管生产设备的内衬带上料机构中，所述浸胶池包括水平设置的胶盆，所述胶盆的内腔侧壁转动连接有若干压辊，所述胶盆的前端设有两个沿竖向并排设置的挤胶辊一，所述挤胶辊一、压辊均与所述支撑轴相平行，两挤胶辊一能对从两者之间通过的内衬带形成挤压。这样的设计使得内衬带上料的过程中，可以预先进行浸胶的工序，使得内衬带能充分浸润胶液后与增强纤维复合，避免产品胶液浸润不充分而影响增强纤维强度的发挥，提升产品的强度。具体在工作过程中，水平布置的胶盆内腔预先注入一定量的胶液，然后引导内衬带连续不断进入胶盆内进行浸润，多个压辊均位于胶液液面之下可对内衬带的位置进行约束限制，使其在胶液内具有更大的浸润长度，浸润充分后的内衬带再脱离胶液后通过胶盆前端设置的两挤胶辊一之间，将其上下表面多余的胶液捋回胶盆内，避免后续缠绕过程中胶量过高而影响产品质量。
在上述的复合管生产设备的内衬带上料机构中，所述胶盆的前端还上还设有两个沿竖向并排设置的挤胶辊二，两个挤胶辊二能对从两者之间通过的内衬带形成挤压，两所述挤胶辊二均与所 述挤胶辊一平行且布置于该挤胶辊一的前侧，所述胶盆的后端设有两个可自转的支撑辊，支撑辊与挤胶辊一相平行，两支撑辊沿水平方向并排设置且能对从两者之间通过的内衬带形成挤压。通过在胶盆的后端设置两个支撑辊，这样内衬带可先经过两个支撑辊之间，两支撑辊转动时可对内衬带上下表面进行撑紧抚平，有利于保证产品质量。通过在胶盆上设置两个挤胶辊二，使两挤胶辊二与挤胶辊一平行且均布置于该挤胶辊一的后方，这样两挤胶辊二可使通过挤胶辊一的内衬带进一步对其支撑和捋胶，保证附着胶量适宜，并给保证内衬带的平整度。
与现有技术相比，本复合管生产设备的内衬带上料机构具有以下优点：
1、本上料机构通过卷圆罩的前上方设置张紧杆一，在张紧杆一的后上方设置张紧杆二，使得在内衬带持续上料的过程中，不仅能保证内衬带平整度高，而且内衬带经过张紧杆二、张紧杆一、卷圆罩以及端口的过程中，内衬带经过多次换向，使得内衬带始终保持一定的张紧度，进而保证了内衬带在芯轴上的卷绕效果，提升了产品质量。
2、本上料机构在内衬带上料的过程中，可以预先对内衬带进行浸胶的工序，使得内衬带能充分浸润胶液后与增强纤维复合，避免产品胶液浸润不充分而影响增强纤维强度的发挥，提升产品的强度。

以下是本发明的具体实施例并结合附图，对本发明的技术方案作进一步的描述，但本发明并不限于这一实施例。
如图1和图2所示，复合管生产设备包括由前之后依次排列的牵引机12、成型模具8、绕线机9和用于放置轴向纱的纱架10，本内衬带上料机构包括支架1和穿过绕线机9的芯轴2，芯轴2的后端连接在支架1上，芯轴2的前端伸入成型模具8内，支架1上设有卷圆罩3和位于卷圆罩3的前上方的张紧杆一1a，卷圆罩3的后上方还设有张紧杆二1c，张紧杆二1c的设置位置高于张紧杆一1a，支架1上位于张紧杆一1a的后侧设有浸胶池7，浸胶池7的设置位置低于张紧杆一1a，张紧杆一1a和张紧杆二1c均水平设置且与芯轴2相垂直。
如图3至图5所示，卷圆罩3包括位于芯轴2左右两侧且相对设置的两块侧板31，两块侧板31的后侧边之间连接有后侧面倾斜朝上的背板32，背板32位于芯轴2的上方，背板32的底边与两块侧板31的底边相连形成开口倾斜朝下的端口33，芯轴2穿过该端口33且端口33的边沿与芯轴2的外周壁之间形成供内衬带穿过的间隙。背板32具有一呈倒三角形的平板部321，平板 部321的顶边与张紧杆一1a相平行，平板部321的顶边上还具有朝前翻出的卷边323。平板部321的左右两侧边分别连接有过渡部322，过渡部322为凸面朝上设置的弧形板体，过渡部322的宽度由上至下逐渐增大，两块侧板31的后侧边均与同侧的过渡部322连接。
如图3所示，支架1上还固连有呈圆筒状且套设在芯轴2上的定型筒4，定型筒4的内径略大于芯轴2的外径，定型筒4位于卷圆罩3的前侧且与卷圆罩3相邻设置。芯轴2的下方设有能进行自转的支撑轴5，支撑轴5与芯轴2相垂直，支撑轴5位于定型筒4的后侧且位于端口33的前侧，支撑轴5与芯轴2之间形成供内衬带穿过并能夹紧内衬带的间隙，支架1上设有用于调节支撑轴5高度位置的调节结构6，本调节结构6可以为丝杠机构。为了便于卷圆罩3和定型筒4的安装，如图1所示，支架1上固连有位于芯轴2上方的安装杆1b，安装杆1b与芯轴2相垂直，两块侧板31的前侧边以及定型筒4的顶面均固连在安装杆1b上。
在制造时，如图6所示，将由内衬带绕成的带卷11水平悬挂于支架1上，设备运转时，内衬带从带卷11上被拉出，拉出之后依次经过浸胶池7、张紧杆二1c然后绕过张紧杆一1a的前侧然后又后方折返，折返后内衬带的中部贴着背板32的后侧面，而内衬带的两侧边分别贴着两块侧板31，由于两块侧板31向下延伸且其底边与背板32的底边相连形成开口倾斜朝下的端口33，且端口33的边沿与芯轴2的外周壁之间仅具有间隙，因此内衬带到达端口33处时，背板32上的内衬带包覆在芯轴2的顶部，而两块侧板31上的内衬带则向芯轴2的底部包绕，最终形成形成圆筒状并卷绕在芯轴2的外周壁上，之后纱架10上的轴向纱包覆在内衬带的外周壁上形成轴向纤维层，轴向纱的长度方向与芯轴2的轴线方向平行，再然后通过绕线机9在轴向纤维层上缠绕周向纱，形成周向纤维层，最后又到达成型模具8内制造形成复合管道。
如图7和图8所示，浸胶池7包括水平设置的胶盆71，胶盆71的内腔侧壁转动连接有若干压辊72，胶盆71的前端设有两个沿竖向并排设置的挤胶辊一73，挤胶辊一73、压辊72均与支撑轴5相平行，两挤胶辊一73能对从两者之间通过的内衬带形成挤压。胶盆71的前端还上还设有两个沿竖向并排设置的挤胶辊二74，两个挤胶辊二74能对从两者之间通过的内衬带形成挤压，两挤胶辊二74均与挤胶辊一73平行且布置于该挤胶辊一73的前侧，胶盆71的后端设有两个可自转的支撑辊75，支撑辊75与挤胶辊一73相平行，两支撑辊75沿水平方向并排设置且能对从两者之间通过的内衬带形成挤压。
本文中所描述的具体实施例仅仅是对本发明精神作举例说明。本发明所属技术领域的技术人员可以对所描述的具体实施例做各种各样的修改或补充或采用类似的方式替代，但并不会偏离本发明的精神或者超越所附权利要求书所定义的范围。
尽管本文较多地使用了1、支架；1a、张紧杆一；；1b、安装杆；1c、张紧杆二；2、芯轴；3、卷圆罩；31、侧板；32、背板；321、平板部；322、过渡部；323、卷边；33、端口；4、定型筒；5、支撑轴；6、调节结构；7、浸胶池；71、胶盆；72、压辊；73、挤胶辊一；74、挤胶辊二；75、支撑辊；8、成型模具；9、绕线机；10、纱架；11、带卷；12、牵引机等术语，但并不排除使用其它术语的可能性。使用这些术语仅仅是为了更方便地描述和解释本发明的本质；把它们解释成任何一种附加的限制都是与本发明精神相违背的。
