Embodiment 1

[0035] Embodiment 1: a kind of low energy consumption sewing machine, as figure 1 Shown, including the sewing machine motor 100, the cam pulley 130, the upper shaft 110, the lower shaft 120 and the speed change mechanism 200 arranged inside the sewing machine, the sewing machine motor 100 and the upper shaft 110 are connected by belt transmission, and the upper shaft 110 and the lower shaft 120 It is connected by a belt drive, wherein the upper shaft 110 is used to drive the needle to move up and down, and the lower shaft 120 is used to drive the shuttle to rotate. Since the above-mentioned specific driving structure is a prior art, it will not be specifically described in this embodiment.

[0036] Such as figure 1 with figure 2 As shown, the transmission mechanism 200 includes an input shaft 210, an input gear 211, an output shaft 220, an output gear 221, an output dial arm 230, a dial 240, a transmission shaft 250, a fixed transmission gear 251, a movable transmission gear...

Embodiment 2

[0048] Embodiment 2: as Figure 4 As shown, the difference from Embodiment 1 is that the transmission mechanism 200 includes an input shaft 210, an input gear 211, an output shaft 220, a transmission chain 270, a guide sprocket 271, a guide assembly 280, a tensioning sprocket 272, a tensioning Assembly 290 and guide frame 140.

[0049] The input shaft 210 and the output shaft 220 are all rotatably installed inside the sewing machine, wherein the axis line of the input shaft 210 is perpendicular to the axis line of the lower shaft 120, and a helical gear 214 is fixedly installed on the lower shaft 120 and the input shaft 210, The input and helical gears 214 on the lower shaft 120 mesh with each other. The input gear 211 is fixedly installed on the input shaft 210 .

[0050] Four output gears 221 are fixedly installed on the output shaft 220 , and the four output gears 221 are arranged at equal intervals, and the diameters of the four output gears 221 are gradually larger or s...

Abstract

The invention discloses a low-energy-consumption sewing machine comprising a sewing machine motor, a cam belt pulley and further a speed change mechanism; the speed change mechanism comprises an inputshaft, an input gear, an output shaft, an output gear, an output shifting arm, and a shifting piece. When the sewing machine motor is started, the input shaft and the input gear may be driven to rotate, the output gear and the output shaft are further driven to rotate, and the cam belt pulley can be driven to rotate by the rotation of the output shaft. When the rotating speed of the cam belt pulley needs to be adjusted, the output shifting arm is driven through the shifting piece to move along the axial lead direction of the output shaft, so that the output gear is driven to slide on the output shaft, the output gear can be adjusted to slide so that the input gear with a small diameter is meshed with the output gear with a large diameter, or the input gear with a large diameter is meshedwith the output gear with a small diameter, the transmission ratio of the input gear and the output gear is changed, and the rotating speed of the cam belt pulley is adjusted.

Description

technical field [0001] The invention relates to the technical field of sewing machines, in particular to a sewing machine with low energy consumption. Background technique [0002] The Chinese patent with the authorized notification number of CN 106192238 A discloses a sewing machine, which includes a sewing machine motor that makes the balance, the needle bar and the shuttle move in linkage through the upper shaft and the lower shaft. Also, a stepping motor is included separately from the sewing machine motor. The bobbin thread supply body is driven by receiving a driving force from the stepping motor, and applies tension to the bobbin thread according to the driving timing and driving amount of the stepping motor. [0003] In the above-mentioned prior art, in order to achieve the bobbin thread supply at an appropriate timing for the sewing conditions, the original single sewing machine motor control mode is provided by a separate feed motor to drive the cam pulley to rota...
