Chain clip link oil gas lubricating device for film stretching production line

Abstract

The invention discloses a chain clip link oil gas lubricating device for a film stretching production line. The chain clip link oil gas lubricating device comprises a row of oil injection air pipes arranged in an operational track of chain clip links, wherein oil gas nozzles at the front ends of the oil injection air pipes are positioned on the front end surface of the track; the positions of the oil gas nozzles are between inner chain plates and outer chain plates of the chain clip links in height; the back ends of the oil injection air pipes are communicated with an oil gas distributor on the back end surface of the track; the oil gas distributors are communicated with an oil gas mixer through a plurality of oil gas pipelines; the oil gas mixer is communicated with an air compressor and an oil tank through an air pressure pipeline and an oil pressure pipeline respectively. A gas-liquid two-phase lubrication technology is adopted, so that the lubricating points of the chain clip links are not influenced by high temperature, and the lubrication requirements of the chain clip links in the film stretching production line under high-temperature, heavy-load and high-speed working conditions are met.

Description

technical field [0001] The invention relates to film stretching production line equipment, in particular to an oil-air lubrication device for chain clips and links of a film stretching production line. Background technique [0002] In the horizontal drawing machine of the film stretching production line, under the condition of high temperature and high speed, the chain composed of chain clips and links runs at high speed on the track, and there is friction between the pin shaft and the sleeve of the chain clip chain link. In order to ensure the pin shaft and the sleeve Wear resistance between the barrels to prolong their service life, lubricating oil must be injected between the pin shaft and the sleeve. [0003] The traditional lubrication method is to inject high-temperature resistant grease into the friction surface between the pin shaft and the sleeve, or use an oil pump to continuously inject lubricating oil into the friction surface between the pin shaft and the sleeve...

AI Technical Summary

Problems solved by technology

[0005] 1. The method of injecting high-temperature-resistant grease is adopted. After a long working time, the lubrication performance of high-temperature-resistant grease will decrease, which will affect the lubrication effect

[0006] 2. The continuous oil injection method is adopted, which consumes a lot of oil and costs high, and lubricating oil with a certain pressure will pollute the film and affect the quality of the film
