Description

Tooth point chain sheet material puncture pressing mechanism and tooth point chain transmission mechanism Technical Field The utility model relates to an upper pressing plate mechanism with a sharp tooth conveying chain. Background The tooth tip chain, namely, the conveying chain with the sharp teeth is commonly used on leather forming equipment, and leather is conveyed by carrying leather after the sharp teeth on the conveying chain pierce the edge of the leather. There are two modes of conveying the leather through the toothed chain, namely, a mode that the conveying chain supports the leather below the leather, as disclosed in patent document CN104828472A, and a conveying mode that the leather is hung below the conveying chain, as disclosed in patent document CN 106429207A. In either way, a pressing mechanism is required to press the edge of the skin into the tines of the conveyor chain. In the prior art, there are two designs, namely, in the first patent document CN205240639U, leather is pressed into the conveying chain tines by a pinch roller fixed above a transmission gear and a front-mounted guide feeding supporting plate mechanism, and in the second patent document CN208843219U, leather is pressed into the conveying chain tines by lifting of a lifting upper guide plate and a lifting lower guide plate. In the actual running process, the two modes are not ideal, the first mode is limited by the matching relation of the transmission gear and the pinch roller, the leather is easy to damage, and the second mode is complex in transmission control due to the fact that the operation of the pressing action is realized through electronic control, and errors are easy to occur on the electronic control layer, such as the fact that the pressing action cannot be performed in time. Disclosure of Invention The utility model aims to solve the problem that the upper leather material of the tooth tip chain conveying mechanism is pressed into the tooth tips of the conveying chain. In order to solve the problems, the utility model adopts the following scheme: The tooth tip chain sheet material puncturing and pressing mechanism comprises a mounting frame, a swinging frame, a pressing wheel and a spring, wherein one end of the swinging frame is arranged on the mounting frame through a horizontal swinging shaft so that the swinging frame can swing on a vertical plane around the swinging shaft, the pressing wheel rotating shaft is horizontally arranged on the swinging frame, an annular groove is formed in the rim of the pressing wheel along the circumferential direction of the pressing wheel rotating shaft, and the spring is connected with the mounting frame and the swinging frame so that the pressing wheel on the swinging frame can generate downward elastic pressure.
