Example Embodiment

[0024] Example one

[0025] Such as figure 1 with figure 2 As shown, the sewing machine in this embodiment includes a casing 1, a sliding rod 4 and a sliding block 2. The sliding block 2 is provided with a penetrating through hole 21, and the sliding rod 4 is slidably inserted in the through hole 21, and the housing 1 A cavity 11 is opened. The lower end of the slide bar 4 is located in the cavity 11, and a swing arm 6 is provided in the cavity 11; the end of the swing arm 6 is hinged with the lower end of the slide bar 4 and the swing arm 6 can swing The sliding rod 4 is driven to reciprocate up and down; the lubrication structure includes an oil storage tank 5 arranged on the casing 1 and an oil immersion part 3 impregnated with grease. The oil storage tank 5 is filled with grease, and the bottom of the oil storage tank 5 is provided with an oil outlet 51. One end of the oil immersion member 3 is located at the oil outlet 51 of the oil storage tank 5, and the other end of the ...

Example Embodiment

[0027] Example two

[0028] Such as image 3 As shown, this embodiment is roughly the same as the first embodiment. The difference is that as a further improvement, in this embodiment, a grease-impregnated linoleum 7 is fixed on the casing 1, and the linoleum 7 is located below the sliding rod 4. , One end of the oil felt 7 extends into the cavity 11 and faces the lower end of the sliding rod 4. When the sliding rod 4 moves downwards, it can come into contact with the oil felt 7. The oil felt 7 lubricates the sliding rod 4 from different directions to improve the lubrication Effect; further, the lower end of the slide bar 4 is immersed with grease oil line 8, the oil line 8 is sleeved at the end of the slide bar 4, the oil line 8 moves with the slide bar 4, at any time against the slide bar 4 and the slider 2 Lubrication is carried out between the sliding rod 4 and the joint of the swing arm 6 to ensure the lubrication effect.

Example Embodiment

[0029] Example three

[0030] This embodiment is roughly the same as the first or second embodiment. The difference is that in this embodiment, the end surface of the oil immersion member 3 facing the sliding rod 4 is in contact with the outer peripheral surface of the sliding rod 4, so that the grease on the oil immersion member 3 It can directly act on the sliding rod 4 to lubricate it.

Abstract

The invention provides a sewing machine and a lubricating structure of a curved needle slide bar on the sewing machine and belongs to the technical field of sewing equipment. The sewing machine solves the technical problems that lubricating oil on the curved needle slide bar on an existing sewing machine is unlikely to leak and the lubricating effect for a long time is not excellent. The sewing machine comprises a housing, a slide bar and a slide block, wherein a perforated through hole is formed in the slide block, and the slide bar is slidably inserted into the through hole. The lubricating structure comprises an oil storage tank arranged on the housing and an oil immersing piece immersed in oil grease; oil grease is filled with the oil storage tank, and an oil outlet is formed in the bottom of the oil storage tank; and one end of the oil immersing piece is located at the oil outlet of the oil storage tank, and the other end of the oil immersing piece faces the outer peripheral surface of the slide bar. According to the sewing machine provided by the invention, lubrication by liquid lubricating oil is changed to lubrication by grease, so that an oil leakage phenomenon in the slide bar part can be reduced and sewing yarns and sewing materials are prevented from being polluted. Meanwhile, by arranging the oil storage tank, the oil immersing piece can be continuously supplemented with grease, so that the long-term lubricating ability and good lubricating effect of the oil immersing piece are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of sewing equipment, and relates to a sewing machine and a lubricating structure for a looper slide bar on the 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. Sewing machine can sew fabrics such as cotton, fiber crops, silk, wool, artificial fiber and products such as leather, plastics, paper, and the stitching that sews out is orderly and beautiful, flat and firm, and sewing speed is fast, easy to use, so it is widely used. The upper looper on the sewing machine is a part of the sewing machine. The upper looper of the sewing machine is connected to the slide bar. The slide bar will wear and generate a lot of heat during high-speed movement, so it needs enough lubricating oil to lubricate it and cool down to ensure the normal operati...
