Knitter table automatic lubricating device and control method

Abstract

The invention discloses a knitter table automatic lubricating device. The knitter table automatic lubricating device comprises a control electromagnetic valve, an air pressure adjusting valve, a double-cylinder diaphragm pump, a lubricating oil storage tank and a three-way valve; an inlet of the control electromagnetic valve is connected with a compressed air intake pipe, and an outlet is connected with an inlet of the air pressure adjusting valve through an electromagnetic valve exhaust pipe; an outlet of the air pressure adjusting valve is connected with an air supply port of the double-cylinder diaphragm pump through a double-cylinder diaphragm pump intake pipe; the three-way valve is mounted in an oil outlet of the double-cylinder diaphragm pump; an oil pressure sensor is mounted on a bypass port in the lower part of the three-way valve; an oil outlet of the three-way valve is connected with one end of a lubricating oil drain pipe; the other end of the lubricating oil drain pipe is positioned above a knitter table; an oil level sensor is mounted at the bottom of the lubricating oil storage tank; and the oil level sensor, the oil pressure sensor and the control electromagnetic valve are respectively connected with a knitter controller. The knitter table automatic lubricating device solves the knitter table automatic lubricating and online monitoring problems, realizes automatic production, and improves the production efficiency.

Description

technical field [0001] The invention belongs to the technical field of mechanical devices, and relates to an automatic lubricating mechanism, in particular to an automatic lubricating device and a control method for a knitting machine table. Background technique [0002] With the rapid development of the domestic economy, especially the rapid development of the automobile industry and high-speed rail, rubber hoses have become an indispensable material in daily life and industrial development. At present, the production of rubber hose is inseparable from the process of weaving. The weaving process needs to be completed by the weaving machine. The table of the weaving machine is the main mechanical part of the weaving machine. It plays a vital role. It can reduce the friction between the spindle and the table, and ensure the smooth movement of the spindle on the table. If the lubrication is not in place, the table will be damaged. This device was invented for the lubrication ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem of automatic lubrication and online monitoring of the knitting machine table. When it is found that the oil pressure of the lubricating oil pump is too low or the oil level of the oil storage tank is too low, the knitting machine will be stopped in time and an alarm will be issued to realize automatic production.
