Automatic lubrication system for shaft of rotating shuttle in many-headed computer embroidery machine

Abstract

This invention puts forward an automatic lubrication system realized by putting heated and atomized lubricating oil on a rotation axis of a brain embroidery machine composed of at least one air compressor with a closed oil tank and conduct pipes, an inlet and an oil fog tube are connected with the oil tank, the other end of the inlet tube is lined to the air compressor, the oil fog tube is connected to spots necessary for lubrication. One controller controls heating wires of the multiple oil tanks, the air compressor sprays to the oil tanks, an oil bath is connected with the tanks and has a level detection device, a pump provides oil to the bath and the machine heads, the level detection device pump is connected with the controller by a control line, the controller controls the heating, spray and level detection process of each tank in circulation, solving the problem of in convenient dropping or dropping too much.

Description

technical field [0001] The invention relates to a lubricating system, in particular to an automatic lubricating system used on the rotary hook shaft of a multi-head computerized embroidery machine, which heats and atomizes lubricating oil and lubricates it with oil mist. Background technique [0002] Multi-head computerized embroidery technology can be briefly described as multiple heads 2 placed on the embroidery machine (see Figure 1), and the upper thread 1 passes through the embroidery needles 3 on the embroidery machine head 2, and reciprocates up and down on the fabric 9 (see Figure 2). superior. Embroidery needle 3 with upper thread 1 penetrates into cloth 9 to form an arc, and the hook tip 503 on the hook 501 winds the upper thread around the bobbin 502 of the bottom thread to form a chain knot formed by the intertwining of upper thread 1 and bottom thread 10 . The higher the rotating speed of the linked rotary hook main shaft 4, the higher the speed of the embroide...

AI Technical Summary

Problems solved by technology

However, since the rotary hook seat 5 is placed under the platen, it is very inconvenient to regularly inject lubricating oil by hand; and the automatic dripping device only solves the problem of inconvenient refueling, and it is difficult to control the dosage added, especially for Lubrication of special materials such as embroidery thread and leather often produces excessive lubricant spillage and pollutes products and the environment.
