高效密封的真空抽头
本技术涉及夹层玻璃加工设备
,具体涉及一种高效密封的真空抽头。
技术介绍
夹层玻璃在制作过程中,因为形状、大小和工艺难度等因素,部分产品不能通过正常辊压加工,这时候需要借助于抽真空生产。抽真空过程中,要求将真空袋内的空气抽出来,该抽头需要承受较高的大气压,通常是将硅胶管埋入真空袋内,然后使用大量密封胶堆积进行密封,密封胶一次性使用,成本较高。因此,需要设计一种可反复利用的真空抽头,以节省加工成本。
技术实现思路
本技术提供一种高效密封的真空抽头,可反复利用,密封效果好。本技术采用如下技术方案:一种高效密封的真空抽头,包括排气基座和上盖,排气基座为圆柱体结构,排气基座中心处设有第一通孔,排气基座底部设有多条排气槽。上盖包括圆柱体基体,基体两端分别设有与基体同心设置的连接轴。上盖中心处设有第二通孔,第二通孔贯穿两个连接轴及基体。下部连接轴外部设有连接螺纹,上盖通过下部连接轴与排气基座连接,下部连接轴通过螺纹连接在排气基座的第一通孔内。上部连接轴外部设有螺纹,连接外部硅胶管时,螺纹可防止硅胶管滑脱,也防止有气体进出,这样硅胶头连接真空抽头时就不用密封胶进行额外的密封,或者使用少量的密封胶在硅胶管和真空抽头连接的尾端密封即可。上盖的基体下表面与排气基座的上表面紧密结合,二者之间设有密封装置。所述排气基座底部设有多条排气槽,排气槽包括圆形槽及十字形槽,圆形槽及十字形槽均与排气基座同心设置,十字形槽设置在圆形槽的外圈,第一通孔、圆形槽及十字形槽三者连通。整个排气基座可直接放置在玻璃上,通过排气槽和通孔进行排气。所述密封装置为两个同心设置的密封圈,进一 ...
