Description

说 明 书 瓦楞辊的风.门控制结构
技术领域
本发明属于包装机械技术领域， 涉及一种瓦楞辊的风门控制结构。
背景技术
目前， 瓦楞机上使用的瓦楞纸成型结构通常包括上瓦辊和下瓦辊， 为了 让瓦楞纸吸附于下瓦辊上， 保证瓦楞纸的顺利上胶， 通常下瓦辊的辊体上会 均布开设气孔，下瓦辊的两端或表面连接抽气装置，通过采取上述技术手段， 瓦楞机在工作时， 瓦楞纸行经下瓦辊时会被吸附于瓦辊上， 保证瓦纸和上胶 辊同步运转。 在实践中发现上述方案普遍存在的一个问题是： 有时候要生产 的瓦楞纸的宽度小于机器 （下瓦辊） 的宽度时， 会造成瓦辊上没有被瓦纸覆 盖的地方会发生气孔漏气的现象， 造成能量损失， 另外， 由于瓦纸贴合于瓦 辊的中间位置处， 而瓦辊上抽气装置是从辊体两端抽气， 这就造成了辊体上 两端部的漏气处， 漏气较大， 并逐渐向中间递减， 进而影响到瓦辊中部表面 对瓦纸的吸附力。
发明内容
本发明的目的在于克服现有技术中存在的不足， 提供一种结构简单、 巧 妙、 合理的瓦楞辊的风门控制结构， 使用该结构可以根据需要生产的瓦楞纸 的需要来调节瓦楞辊上通风孔的数量。
按照本发明提供的技术方案： 一种瓦楞辊的风门控制结构， 特征在于： 包括瓦楞辊， 所述瓦楞辊主体部分呈圆环状， 所述瓦楞辊的圆环部分均布开 设若干真空孔， 每个真空孔内两端均滑动设置有风门管， 瓦楞辊外圆周面上 均布开设若干结构相同的主风道， 每个主风道下端均沟通真空孔， 所述风门 管外壁贴合于真空孔的内壁上，所述风门管上对应于主风道处开设有进风口， 且所述风门管上最外侧进风口的孔径和主风道的孔径相同， 且风门管上从第 二个进风口开始， 每一个进风口的孔径均比前一个进风口的孔径大出一个主 风道的孔径大小； 所述风门管内端靠近瓦楞辊中心处开设有出风口， 所述出 风口沟通瓦楞辊内腔。
作为本发明的进一步改进， 所述瓦楞辊两端分别具有中空连接座， 所述 连接座外侧设有抽气口。
本发明与现有技术相比， 优点在于： 本发明通过技术改进， 在现有的瓦 楞辊的内腔两端分别设置一风门管， 由于风门管可以在瓦楞辊内轴向移动， 可以根据待生产的瓦楞纸的宽度需要，调节风门管在瓦楞辊内部轴向的位置， 将瓦楞纸两侧瓦楞辊辊体上的主风道关闭， 来保证瓦楞辊对应于瓦楞纸处的 主风道处产生的空气负压可以将瓦楞纸完全吸附于瓦楞辊上， 达到节能高速 的目的。
附图说明
图 1为本发明的结构示意图。
图 2~5为本发明的使用状态局部剖视图。
具体实施方式
下面结合具体附图和实施例对本发明作进一步说明。
如图 1~5所示， 包括瓦楞辊 1、 风门管 2、 主风道 3、 出风口 4、 进风口 5、 连接座 6、 真空孔 7等。
如图 1所示， 本发明是一种瓦楞辊的风门控制结构， 包括瓦楞辊 1， 所 述瓦楞辊 1主体部分呈圆环状， 所述瓦楞辊 1的圆环部分均布开设若干真空 孔 7，每个真空孔 Ί内两端均滑动设置有风门管 2，瓦楞辊 1外圆周面上均布 开设若干结构相同的主风道 3，每个主风道 3下端均沟通真空孔 7，所述风门 管 2外壁贴合于真空孔 7的内壁上， 所述风门管 2上对应于主风道 3处开设 有进风口 5， 且所述风门管 2上最外侧进风口 5的孔径和主风道 3的孔径相 同， 且风门管 2上从第二个进风口开始， 每一个进风口的孔径均比前一个进 风口的孔径大出一个主风道 3的孔径大小； 所述风门管 2内端靠近瓦楞辊 1 中心处开设有出风口 4， 所述出风口 2沟通瓦楞辊 1内腔。
所述瓦楞辊 1两端分别具有中空连接座 6， 所述连接座 6外侧设有抽气 口。
本发明的工作过程如下： 如图 2〜5所示， 主风道 3的孔径大小以 2mm， 风门管 2上的进风口 5的尺寸满足： 最外侧的进风口 5的孔径为 2醒， 从外 侧第二个进风口 5开始算起， 后一个进风口 5的孔径均比前一个进风口 5的 孔径大 2mm， 即进风口 5的孔径大小依次为 2讓、 4mm、 6腿、 8腿 。 当风 门管 2外侧端部贴合于瓦楞辊 1端部设置， 即， 风门管 2没有向瓦楞辊 1内 腔中移动时， 每个进风口 5均是开口处的后端和主风道 3的后端相对齐。 如 图 2所示， 风门管 2沿轴向向瓦楞辊 1内侧移动 2mm， 此时瓦楞辊 1上的第 一个主风道 3被关闭； 图 3示出了， 当风门管 2向内移动 4mm时， 瓦楞辊 1 上的前两个主风道 3均被关闭掉；如图 4所示， 当风门管 2向内移动 6匪时， 瓦楞辊 1上的前三个主风道 3均被关闭掉； 如图 5所示， 当风门管 2向内移 动 8mm时， 瓦楞辊 1上的前四个主风道 3均被关闭掉。 依次类推， 根据要生 产的瓦楞纸的宽度来决定风门管 2在瓦楞辊 1轴向上的移动距离， 将暂时不 需要的主风道 3关闭掉， 既实现节约能源的目的， 同时将超出瓦楞纸外侧的 主风道 3关闭还可以保证瓦楞辊 1中部的主风道 3有足够的吸附力将瓦楞纸 紧密吸附于瓦楞辊 1上。
本发明通过技术改进， 在现有的瓦楞辊的内腔两端分别设置一风门管， 由于风门管可以在瓦楞辊内轴向移动，可以根据待生产的瓦楞纸的宽度需要， 调节风门管在瓦楞辊内部轴向的位置， 将瓦楞纸两侧瓦楞辊辊体上的主风道 关闭， 来保证瓦楞辊对应于瓦楞纸处的主风道处产生的空气负压可以将瓦楞 纸完全吸附于瓦楞辊上。
