Problems solved by technology

[0004] In the above-mentioned patent documents, the liquid lubricating oil is supplied to the outer wall of the slide bar through the oil line. The lubricating oil is not easy to control. When the oil in the oil line is large in the initial stage, it is easy to drip out. After a long time of use, the oil in the oil line becomes less, and the slide bar Can not wait for sufficient lubrication, affecting the lubrication effect

Embodiment 1

[0025] Such as figure 1 with figure 2 As shown, the sewing machine in this embodiment includes a casing 1, a slide bar 4 and a slide block 2, the slide block 2 is provided with a through hole 21 through which the slide bar 4 slides and is inserted in the through hole 21, and the casing 1 A cavity 11 is provided, the lower end of the slide bar 4 is located in the cavity 11, and a swingable 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 Drive the slide bar 4 to reciprocate up and down; the lubricating structure includes an oil storage tank 5 arranged on the casing 1 and an oil-immersed part 3 soaked 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 component 3 is located at the oil outlet 51 of the oil storage tank 5 , and the other end of the oil immersion componen...

Embodiment 2

[0028] Such as image 3 As shown, this embodiment is roughly the same as Embodiment 1, the difference is that, as a further improvement, in this embodiment, a linoleum 7 soaked in grease is fixed on the casing 1, and the linoleum 7 is located below the slide bar 4 One end of the linoleum 7 extends into the cavity 11 and faces the lower end of the slide bar 4. When the slide bar 4 moves down, it can be in contact with the linoleum 7. The linoleum 7 lubricates the slide bar 4 from different directions to improve the lubrication. effect; further, the lower end of the slide bar 4 is soaked with grease oil line 8, the oil line 8 is sleeved on the end of the slide bar 4, the oil line 8 moves with the slide bar 4, and the slide bar 4 and the slide block 2 are connected at any time. Lubricate between the joints of the slide bar 4 and the swing arm 6 to ensure the lubrication effect.

Embodiment 3

[0030] This embodiment is substantially the same as Embodiment 1 or Embodiment 2, except that in this embodiment, the end surface of the oil-soaked part 3 facing the slide bar 4 is in contact with the outer peripheral surface of the slide bar 4, so that the grease on the oil-soaked part 3 It can act directly on the slide 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...
