Description

一种大口径无箍高密封性塑料桶
技术领域
本发明涉及大口径塑料桶密封领域，具体涉及一种大口径无箍高密封性塑料桶。
背景技术
现在国内外聚四氟乙烯等高档的粉状或液体的，有防潮、密封要求的化工原材料，一般都采用有箍的塑料桶，通过卡箍进行桶盖的固定勒紧，提高桶盖的密封性，但这种箍紧原理塑料桶的密封性只能达到一般的水平，很难达到高密封的效果；或者在桶内设置内胆或尼龙袋进行二层包装，即由于普通的大口径塑料桶密封性较差，因此需要利用内胆或尼龙袋先对物品进行首次封装，而后通过塑料桶进行二次封装，进而提高密封性，防止泄露。
但上述两种包装方式，通过卡箍进行密封的塑料桶在加工生产封装过程中需要包含锁紧卡箍的工序，且该工序具体流程需要套箍、卡紧、旋转锁定卡箍等步骤，且这个过程只能用人工操作完成，费时费力且容易出现锁定不可靠的现象，同时由于步骤较多也很那实现完全自动化的批量生产封装。而二次包装的方式，即设置有内胆或尼龙袋的包装方式，需要在塑料桶内设置内胆或尼龙袋，大大提高了企业的生产成本，且同样不适用于大批量的自动化生产封装。因此为解决上述问题，需要一种结构简单、密封效果好且适合大批量自动化封装的大口径无箍高密封性塑料桶。
发明内容
本发明所要解决的技术问题是：提供一种结构简单、密封性好且适合大批量自动化生产封装的大口径无箍高密封性塑料桶。
本发明解决上述技术问题所采用的技术方案为：一种大口径无箍高密封性塑料桶，包括具有沿口部的桶体和用于密封沿口部的封盖，所述桶体的沿口部的侧边设置有密封环，所述密封环的外周面为第一密封面，所述桶体的外侧面还设置有环形的卡圈，所述的卡圈位于所述的密封环的下方，所述的封盖设置有用于安装沿口部的密封槽，所述密封槽包括密封槽内侧壁和密封槽外侧壁，所述密封槽内侧壁的外侧面与沿口部的内壁相密封贴紧配合，所述的密封槽外侧壁的内侧面设有与第一密封面密封配合的第二密封面，所述的封盖的外周面设置有与卡圈相对应的攀钩条，所述的攀钩条的内侧壁设置有卡圈相卡紧的凸缘。
更进一步地，所述的攀钩条与密封槽外侧壁的下端相连接，所述的攀钩条与密封槽外侧壁连接处的内侧设置有撕裂槽；有点在于撕裂槽的设置可大大提高安装后封盖拆卸的便捷性。
更进一步地，所述的封盖还设有开盖扳手，所述的攀钩条呈环形设置在密封槽外侧壁的下方，且所述的攀钩条的首尾两端分别位于开盖扳手的两侧，所述攀钩条的首端设置有便于撕开攀钩条的拉条；有点在于环形设置的攀钩条可有效保障封盖固定的可靠性，且拉条和撕裂槽的设置便于攀钩条的撕开，从而便于封盖的拆卸。
更进一步地，所述的开盖扳手与密封槽外侧壁的连接处设置有撕裂槽；有点在于撕裂槽的设置可便于开盖扳手的掀起或打开。
更进一步地，所述的桶体的外侧还设置有环形的挡圈，所述的开盖扳手的下端部延伸至挡圈的上端面；优点在于开盖扳手延伸至挡圈上端面可有效减少开盖扳手意外打开的可能性，提高桶体的可靠性。
更进一步地，所述的密封环的外周面设有竖直的第一密封面，所述密封槽外侧壁的内侧面设置有凸环，所述的凸环设有与第一密封面密封配合的第二密封面。
更进一步地，所述沿口部的上边沿厚度大于第一密封面、第二密封面之间的距离；优点在于过盈配合的沿口部与密封槽可有效提高桶体的密封性。
更进一步地，所述沿口部的上边沿厚度与第一密封面、第二密封面之间的距离之差为0.1mm～1mm ；优点在于当差值位于该区间内时，桶体沿口部可安装至密封槽的内部较深位置，且密封效果较好、固定较为可靠，同时便于封盖的安装。
更进一步地，所述的凸环的下端面设置有便于桶体安装的倾斜面；优点在于倾斜面的设置便于沿口部的导向定位安装，从而便于企业自动化生产时设备的定位封装，降低对设备精准度的要求，提高设备的容错率。
与现有技术相比，本发明的优点是通过设置的密封槽与沿口部的密封配合可实现桶体的高密封性封装，具体通过将密封环设置的第一密封面与密封槽外侧壁的内侧面设的第二密封面的紧密配合实现密封，且凸环的下端面设置有便于桶体安装的倾斜面，因此桶体的沿口部可较为容易的安装在密封槽内，起到导向安装的作用，便于自动化生产。同时桶体的外侧面设置的卡圈与相对应的攀钩条相卡接，实现封盖的固定，避免封盖安装完成后的轴向移动，从而进一步确保桶体密封的可靠性。由此可知桶体和封盖的密封以及固定仅通过一道工序即可压紧完成，便于操作，工序简单，因此便于企业实现大批量的自动化密封包装，实现自动化工厂生产，提高企业的生产效率，大大节省人力，缩短生产周，从而满足现代企业工业智能化、全自动化发展的要求。当需要拆卸时，撕裂槽的设置便于操作员沿撕裂槽撕开攀钩条，使得封盖在密封可靠的同时拆卸也较为简单。

上述开盖扳手10与密封槽外侧壁5.2的连接处还可设置有撕裂槽8，开盖扳手10上的撕裂槽8与攀钩条7上的撕裂槽8相对齐。设置的撕裂槽8便于操作员沿撕裂槽8撕掉开盖扳手10，而后便于操作员通过拉条11将攀钩条7沿撕裂槽8撕开。其中撕裂槽8的厚度为：0.3mm～0.6mm，宽度为：0.5mm～0.6mm适宜。
上述沿口部3的上边沿厚度大于第一密封面4.1、第二密封面5.4之间的距离。沿口部3的上边沿厚度与第一密封面4.1、第二密封面5.4之间的距离之差为0.1mm～1mm ，最好选择为0.5mm。
上述的桶体1和封盖2的原料采用PP、PE或PE的改性工程塑料制作的，且原料在注塑成型后的制品收缩率＜1.5%，从而避免影响制品的密封性。
本发明的使用过程为：将封盖2压盖在桶体1的上端，即将桶体1的沿口部3安装在密封槽5内，由于凸环5.3的下端面设置有便于桶体1安装的倾斜面5.5，因此桶体1的沿口部3可较为容易的安装在密封槽5内，起到导向的作用，便于自动化生产。由于上述沿口部3的上边沿厚度大于第一密封面4.1、第二密封面5.4之间的距离，因此密封槽内侧壁5.1的外侧面与沿口部3的内壁相密封贴紧配合，凸环5.3上设置的第二密封面5.4与密封环4上的第一密封面4.1紧密配合，实现过盈配合即通过封盖2自身的塑性与桶体1的沿口部3实现密封配合，实现双面密封提高桶体1密封的可靠性。在此过程中，桶体1的外侧面设置的卡圈6与相对应的攀钩条7相卡接，具体为卡环与攀钩条7上设置的凸缘9相卡接，实现封盖2的固定，避免封盖2安装完成后的轴向移动，从而进一步确保桶体1密封的可靠性。当需要拆卸封盖2时，通过设置的拉条11将攀钩条7沿撕裂槽8撕开，即卡环与凸缘9相分离解除卡紧状态，此时操作员可将封盖2向上掀开。
以上所述实施例仅为本发明的优选实施例，其描述较为具体和详细，但并不能因此而理解为对本发明专利范围的限制。应当指出的是，对于本领域的技术人员来说，在不脱离本发明构思的前提下，还可以做出若干的变形和改进，这些都属于本发明的保护范围。
