Abstract
A mechanical rocker-arm type vertical feeding cushioning device, consisting of two identical cushioning units and a box body (7). The two cushioning units are respectively arranged with a certain height difference on the inner side of the box body (7). Each cushioning unit consists of a cushioning mechanism and a fixing hinge mechanism. The cushioning mechanism is composed of a cushioning plate (1), a spring (5) and a balance weight (6). The fixing hinge mechanism is composed of a hinge plate (2), a right angle circular rod (3) and an elastic limiting device (4). The cushioning plate (1) is fixed to the hinge plate (2) via connection holes and using bolts. The hinge plate (2) is welded to the right angle circular rod (3). The elastic limiting device (4) consists of two elastic limiting plates and a hollow iron ring in a welded manner. The right angle circular rod (3) is connected to the elastic limiting device (4) in a sleeved manner via the hollow iron ring of the elastic limiting device (4). An upper end of the spring (5) is connected to the right angle circular rod (3), and the balance weight (6) is suspended at a lower end of the spring (5). Material is fed to the cushioning pl…
