The invention discloses an intermittent high-speed feeding device and belongs to the field of product high-speed production line logistics. The intermittent high-speed feeding device is applicable to other similar feeding ways. In the situation that the stamping rhythm of a punch press is very high, the product feeding device adopts a way of being linked with a sliding block of the punch press to realize strict matching of a product feeding moment and movement moment of working equipment. The intermittent high-speed feeding device provided by the invention uses an intermittent gear driving mechanism for driving a cam driving mechanism, then uses the cam driving mechanism for driving a connecting rod stroke lengthening driving mechanism, and finally uses the connecting rod stroke lengthening driving mechanism for driving a product containing frame and a guide pair to realize high-speed feeding. The intermittent high-speed feeding device can realize one-time feeding during a plurality of high-speed operations of the working equipment, and the feeding is completed within the time for one-time operation of the working equipment. The intermittent high-speed feeding device provided by the invention is safe and reliable.
