Abstract

The utility model provides an oil injection lubricating device for a transverse zipper clip chain link in a film stretching production line, a pin shaft sleeve matching surface of the chain clip chain link is communicated, an oil injection inlet is arranged above the pin shaft sleeve matching surface, and a chain wheel is provided with an oil injection mechanism for injecting oil to the oil injection inlet; the oil injection mechanism comprises a lubricating oil runner, a nozzle, an oil injection pipe, a hydraulic station, an oil injection electromagnetic valve and a lubricating grease conveying pipe; the chain wheel is divided into N fan-shaped oil spraying areas along the circumference, and N corresponding lubricating oil flow channels are arranged in a chain wheel center extension shaft at the top of the chain wheel. The oil outlet end of the hydraulic station is connected to the oil injection electromagnetic valve and connected into the corresponding lubricating oil flow channels, and the nozzles are connected with the corresponding lubricating oil flow channels through oil injection pipes. And the nozzle working position proximity switch is matched with the arc bulge to output an oil injection signal. The oil injection lubricating device for the transverse zipper clip chain link of the film stretching production line can accurately and uniformly supply oil to lubricate the chain clip chain link, and has the advantages of small mechanical wear, stable oil injection, accuracy and energy conservation.
