Embodiment 1

[0026] like figure 1 and 2 As shown, the sewing machine includes a casing 1, the casing 1 has an oil cavity, and the oil cavity is a closed cavity. The oil leakage prevention device includes a pressure relief member arranged on the casing 1. The pressure relief member communicates with the oil chamber and can reduce the air pressure in the oil chamber to be lower than or equal to atmospheric pressure. There is also a pressure relief member and the oil chamber. With oil filter 4.

[0027] Specifically, the pressure relief component is a negative pressure generator 2 , and the outer wall of the casing 1 has a protruding connecting boss 1b, and the negative pressure generator 2 is connected to the connecting boss 1b through a connecting bracket 7 . The connecting bracket 7 is in the shape of a strip plate, one plate surface of the connecting bracket 7 is fixed on the connecting boss 1b by screws, the other plate surface of the connecting bracket 7 has a step, the negative press...

Embodiment 2

[0031] The structure and features of this embodiment are basically the same as those of Embodiment 1, the difference is that: the casing 1 is provided with a connection port communicating with the oil chamber, the connection port is provided with a pipe joint, and a filter is provided between the pipe joint and the connection port. The oil tank, the pressure relief part is a one-way air outlet valve, and the one-way air outlet valve is connected with the pipe joint. The setting of the one-way air outlet valve makes the air inside the oil chamber of the casing 1 only flow outward in one direction, so that when the air pressure in the oil chamber of the casing 1 rises, it can automatically flow outward due to the pressure difference. Exhaust and pressure relief, so that the atmospheric pressure in the oil chamber is less than or equal to the outside world, and the oil filter on the pipe joint can filter the oil mist during the pressure relief process, preventing the oil mist from...

Abstract

The invention provides an oil-proof device for sewing machine and belongs to the technical field of machinery with an aim to solve the problem that an oil-proof device for the existing sewing machines is hard to be effectively controlled in oil leakage. The oil-proof device comprises a main case provided with a sealed oil chamber therein and a pressure relief part arranged on the main case, the pressure relief part is communicated with the oil chamber and can lower air pressure in the oil chamber to be lower than or equal to barometric pressure, and an oil filter is further arranged between the pressure relief part and the oil chamber. By the arrangement of the pressure relief part on the main case, pressure of the oil chamber is released through the pressure relief part, oil mist produced during pressure relief is filtered through the oil filter, pressure lower than or equal to the outer barometric pressure can be formed in the oil chamber of the main case, and slight leakage of oil fluid can be effectively prevented under the action of external barometric pressure.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to an oil leakage prevention device of a sewing machine. 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. Existing sewing machines generally have oil leakage when they are running for a long time. According to the traditional method of changing or adding sealing gaskets to prevent oil, the large leakage of oil can be controlled. [0003] As Chinese patent application (application number: 03124915.9) discloses a kind of oil leakage prevention device of sewing machine, comprises sewing machine main body, is fixed on the annular guide member on the sewing machine main body, is supplied with lubricating oil in the sewing machine main body, penetrates the aforementioned guide The driving shaft whose member is driven to move forwar...
