Sewing machine oil box

Abstract

The invention relates to a sewing machine oil box, including a box body and a box cover. The box body and the box cover are connected in a sealed manner through screws. The bottom of an inner cavity of the box body is provided with a first oil cavity. A supporting plate A is arranged on the upper part of the first oil cavity. The supporting plate A and the inner wall of the box body are fixedly connected to form a second oil cavity. A supporting plate B is arranged on the upper part of one side of the supporting plate A. The supporting plate B and the inner wall of the box body are fixedly connected to form a third oil cavity. A filter screen is connected between the supporting plate A and the supporting plate B. One side of the box body, close to the supporting plate A, is provided with an oil filling port, and the oil filling port is above the supporting plate A. One side of the box body, close to the oil filling port, is connected with an oiling groove. The bottom of the oiling groove is inclined. The oil box is simple in structure and rational in design, and can effectively return oil and supply oil, and can effectively prevent oil from leaking out. The oil box can filter scrapiron and impurities, preventing a sewing device from being damaged when oil is supplied. The oil box can easily inject oil liquid, and use is convenient.

Description

technical field [0001] The invention relates to a sewing machine oil box, which belongs to the technical field of sewing machine equipment. Background technique [0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing material. The sewing machine can sew fabrics such as cotton, hemp, silk, wool, and artificial fibers, and products such as leather, plastics, and paper, and the stitches that are sewed are not only neat and beautiful, flat and firm, but also have a fast sewing speed and are easy to use. Therefore, the sewing machine It is widely used in the sewing industry. Sewing machines are simply divided into household sewing machines and industrial sewing machines. Most of the industrial sewing machines are general-purpose sewing machines, including lockstitch sewing machines, chain sewing machines, overlock sewing machines and interlock sewing machines...

AI Technical Summary

Problems solved by technology

During the working process of household sewing machines and industrial sewing machines, a certain amount of iron filings will be generated due to the mutual friction of certain mechanisms, which may cause some iron filings to exist in some mechanisms inside the machine or in the inner cavity of the casing, and the iron filings will flow with the oil. If it flows into the bottom oil box and accumulates in the box body, some iron chips may be sucked up by the oil return pump and enter the oil supply pipeline, or be stirred up, causing damage to the oil circuit and mechanism

And the structure of the existing sewing machine oil box is very simple, just an open rectangular box body installed under the base plate, which is used to accept the oil fluid returned by the lubricating mechanism, and its position is set according to the needs of the oil circuit

During use, the head of the sewing machine often needs to be turned up for function adjustment or maintenance. When the oil box is tilted, the oil will easily leak out, contaminate the equipment and the sewing material at the same time, causing trouble

For this reason, in use, sometimes the problem is solved by installing less oil, but it causes frequent trouble of adding oil, which is extremely inconvenient. Therefore, further improvement is needed
