Oil cooling device

Abstract

The invention belongs to the technical field of sewing machines, and particularly relates to an oil cooling device which comprises a shell. An oil pump is arranged in the shell, an output end of the oil pump is connected with an input end of a first pipe, an output end of the first oil pipe is connected with an input end of a second oil pipe through an oil filtering pipeline in the shell, an output end of the second oil pipe is connected with an input end of an oil cooler, an output end of the oil cooler is connected with an input end of a third oil pipe, and an oil spraying end of the third oil pipe is arranged and faces to the inner wall of the shell. According to the device, cooling of lubricating oil is accelerated by the oil cooler, lower balanced temperature is acquired, hand scalding of a working table can be prevented, and the service life of a sewing machine can also be prolonged.

Description

Technical field: [0001] The invention belongs to the technical field of sewing machines, in particular to an oil cooling device. Background technique: [0002] With the continuous improvement of the technical level of the sewing machine industry, sewing machines have begun to develop towards portability and miniaturization. However, the ensuing problem is that the heat dissipation of the sewing machine is insufficient, and the equilibrium temperature of the sewing machine rises, which leads to an excessively high temperature of the workbench and reduces the work efficiency of the operator. [0003] In order to better reduce the temperature of the sewing machine body, it is usually achieved by improving the oil circuit system, but the sewing machine itself has a compact structure, and the excess heat has been dissipated, which leads to the inability to effectively reduce the temperature of the sewing machine body. Invention content: [0004] The object of the present inven...
