The invention relates to an anti-overload mechanism for intermittent feeding device and its assembly method, including a rack, a pawl rod with a ratchet wheel rotated at the lower end of the rack, a driving rod with a horizontal setting at the upper end of the pawl rod, a finite position convex part in the middle of the driving rod, and a front end sleeved on the driving rod. A compression spring acting on the limit convex part is also provided with a supporting seat which is connected with the back end of the compression spring. The supporting seat is hinged with an actuating rod which is driven by a driving mechanism to swing for driving the driving rod to move laterally. The middle part of the pawl bar is hinged with a pawl whose lower end matches the pawl wheel. The upper end of the connecting rod is fixed with a transversely arranged connecting rod, the back end of the connecting rod is provided with a cam plate, the cam plate is provided with an inverted L-groove, the driving rod is fixed with a pin which matches the L-groove, and a sliding pin is arranged on the rear side of the cam plate on the frame, and the rear side of the sliding pin is provided with a driving mechanism. A micro switch connected to the power supply. The structure of the overload prevention mechanism applied to the intermittent feed device is compact and effectively overcomes overload production problems.

应用于间歇进给装置的防止过载机构及其装配方法
本专利技术涉及一种应用于间歇进给装置的防止过载机构及其装配方法。
技术介绍
目前的间隙进给机构多采用棘轮机构,但如果对棘轮机构的过载问题没有很好地加以考虑,就容易引起棘爪或棘爪轴的破坏。防止过载的简单方法是采用安全销作为安全机构,但是,被剪断的安全销的处理也是十分麻烦。为此,需要一种应用于间歇进给装置的防止过载机构。
