Description

Technical Field

[0001] The utility model relates to the technical field of sewing machines, in particular to an oil supply device for a women's clothing sewing machine. Background Art

[0002] In order to help reduce the friction between the parts of the sewing machine, lubricating oil is required for lubrication. The existing patent (Announcement No.: CN219752658U) discloses an automatic oil supply device for sewing machine lubricating oil. The utility model sets a fixing device to make the installation of the oil supply device tighter and the disassembly more convenient. However, in actual applications, the oil supply pipeline is usually used to deliver the lubricating oil to multiple parts that need lubrication. On the one hand, when the temperature is low in winter, the lubricating oil will become thicker and less likely to flow, affecting the outward transportation of the lubricating oil. After being placed for a period of time, oxidation may occur to produce sediment. In addition, some sewing machines still use an open oil pan as a lubricating oil storage structure, which will further increase the impurities in the lubricating oil and seriously affect the transportation of the lubricating oil. To this end, we propose an oil supply device for women's sewing machines. Utility Model Content

[0003] In order to solve the above problems, the utility model provides an oil supply device for a women's clothing sewing machine.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] An oil supply device for a women's clothing sewing machine is designed, comprising a shell one, a transition cylinder with openings at both ends coaxially arranged in the shell one, a heating tube arranged between the transition cylinder and the inner wall of the shell one, a temperature sensor installed in the shell one, an oil guide head connected to the transition cylinder arranged at one end of the shell one, a shell two detachably connected to the other end of the shell one, a filtering mechanism connected to the transition cylinder arranged in the shell two, the filtering mechanism comprising a filtering cylinder with multi-stage filter screens arranged therein, and a plurality of oil supply pipes connected to the shell two.

[0006] In the above solution, the heating tube is arranged in a spiral shape and is fixed to an inner wall of the outer shell.

[0007] In the above scheme, the oil guide head is conical, and the end with a smaller radius of the oil guide head is connected to a quick-release tube, and the other end of the oil guide head is fixed with a connecting sleeve threadedly connected to the transition tube.

[0008] In the above scheme, an annular plate is provided at one end of the first shell away from the oil guide head, and an assembly set threadedly connected to the annular plate is fixed on the second shell.

[0009] In the above scheme, an oil outlet pipe communicating with the filter cartridge is fixed on the second housing, and the oil outlet pipe is connected to the oil delivery pipe.

[0010] In the above solution, the filter cartridge has an opening at one end close to the oil outlet pipe, and the other end is provided with a mesh hole and connected to the assembly set.

[0011] In the above scheme, the multi-stage filter includes filter one and filter two, a magnetic block is fixed to the inner wall of the filter cylinder, filter one is a magnetic metal filter one, and filter one and filter two are fixed by a connecting rod.

[0012] The advantages and beneficial effects of the utility model are as follows: by arranging a transition tube, a temperature sensor and a heating pipe, the lubricating oil transported through the oil storage device is introduced into the transition tube, and the temperature sensor is used to detect the real-time temperature. When the temperature is too low and below the threshold, the heating pipe is started to start working, releasing heat to the transition tube, and gradually heating the lubricating oil in the transition tube. Compared with the prior art, in an environment with relatively low temperature, the lubricating oil can be properly heated by the heating pipe to increase its temperature, reduce the viscosity of the lubricating oil, and thus improve the fluidity of the lubricating oil, which is beneficial to the transportation of the lubricating oil. By arranging a filtering mechanism and utilizing a filter tube to receive the lubricating oil in the transition tube, and in conjunction with filter screen one and filter screen two, impurities in the lubricating oil are filtered. Compared with the prior art, impurities in the lubricating oil can be effectively prevented from clogging the oil delivery pipe, which is beneficial to the external transportation of the lubricating oil.
