Description

Technical Field

[0002] When packaging bottled items, it is necessary to use an automatic capping machine to install the cap on the upper end of the bottle body to achieve the effect of sealing and protecting the bottled items. When the existing capping machines use a grasping structure to grasp the cap, in order to avoid damage to the periphery of the cap, most of them still use a pneumatic method to position the cap. However, the grasping structure of the existing capping machine mainly adopts a fixed setting, so that it can only fix the cap of a single diameter. When the diameter of the cap changes, it will be difficult to continue to fix the cap, which obviously limits the performance of the device. For this reason, we propose a fixing device for an automatic capping machine. Utility Model Content
