中文摘要:

为了解决目前3瓣卡爪旋盖头结构复杂、成本高，以及简易旋盖头兼容性差、生产效率低等技术缺陷，课题组设计了一种3瓣式自动抓紧旋盖头。3瓣式自动抓紧旋盖头主要由锥套、3瓣齿牙滑套、定位体、滑动体、复位弹簧和3个定位螺钉等组成。滑动体在旋盖头内腔的中间位置，在旋盖头下降和上升过程中，塑料盖或复位弹簧对滑动体的压力推动3瓣齿牙滑套在锥套内腔上下移动，使其下端收缩或张开，因此不需要设置驱动源。该旋盖头结构简单，可适用于各种旋盖设备，能自动抓紧或脱离塑料盖而完成旋盖任务，值得在包装领域推广。

英文摘要:

In order to solve the technical defects such as complex structure, high cost, poor compatibility, and low production efficiency of the current three petal claw capping head, a three petal automatic clamping capping head mainly composed of a conical sleeve, a three petal toothed sliding sleeve, a positioning body, a sliding body, a return spring and three positioning screws was designed.The sliding body was in the middle of the inner cavity of the capping head. During the descending and ascending process of the capping head, the pressure exerted on the sliding body by the plastic cap or the return spring could push the three petal toothed sliding sleeve to move up and down in the inner cavity of the cone sleeve, making its lower end shrink or open. Therefore,the capping head could automatically clamp or disengage the plastic cap to complete the capping task without drive source. This capping head has a simple structure and is suitable for various capping equipment. The proposed capping head can automatically grip or detach the plastic cover to complete the capping task, and is worth popularizing in the packaging field.
