Household multifunctional computer sewing machine

Abstract

A household multifunctional computer sewing machine comprises a sewing machine outer housing, wherein a built-in housing is arranged in the sewing machine outer housing; a main shaft is arranged on the built-in housing; the main shaft is connected with a lower shaft; an output end of the main shaft is connected with a needle rod; an output end of the lower shaft is connected with a rotating shuttle and a feed dog; a main controller is arranged in the built-in housing; a clutch pin is fixed on the main shaft; the clutch pin is connected with a winder pusher dog. The sewing machine has the benefits that the structure is reasonable and compact, the using is convenient and reliable, the type and function of a stitch pattern is greatly increased by adopting a stitch pattern formation mechanism controlled by the main controller, the winding of an operator is convenient by adopting a winder structure of an auto clutch, the consumption of materials can be lowered by adopting the built-in housing, the process technology is simplified, the environmental pollution is effectively eliminated, and therefore, the sewing machine is suitable for household use, has good using effect, and facilitates the popularization.

Description

technical field [0001] The invention belongs to textile equipment, in particular to a household multifunctional computer sewing machine. Background technique [0002] At present, the multifunctional sewing machines for home use circulating on the market usually include a main motor, a main shaft, a cam, etc. in structure, and its stitch pattern forming mechanism is composed of a series of cams. When it is necessary to sew a certain stitch pattern When the stitch pattern selection button is turned, the corresponding cam is connected to the main shaft. When the stitch pattern is sewn, the main motor drives the main shaft to rotate, and the cam rotates accordingly. Quantitative changes are realized, thereby converting the concave-convex track of the cam into a stitch pattern. Since each cam corresponds to a stitch pattern, and the internal space of the sewing machine is limited, too many cams cannot be installed, so that the stitch pattern that can be sewn It is limited to a c...

[0002] At present, the multifunctional sewing machines for home use circulating on the market usually include a main motor, a main shaft, a cam, etc. in structure, and its stitch pattern forming mechanism is composed of a series of cams. When it is necessary to sew a certain stitch pattern When the stitch pattern selection button is turned, the corresponding cam is connected to the main shaft. When the stitch pattern is sewn, the main motor drives the main shaft to rotate, and the cam rotates accordingly. Quantitative changes are realized, thereby converting the concave-convex track of the cam into a stitch pattern. Since each cam corresponds to a stitch pattern, and the internal space of the sewing machine is limited, too many cams cannot be installed, so that the stitch pattern that can be sewn It is limited to a certain number, and can only reach more than a dozen stitch patterns at most, and the connection between the cam and the main shaft requires a complicated stitch clutch mechanism, so higher technology and more labor are required to assemble the sewing machine , which increases the production cost of the sewing machine, and these common household multifunctional sewing machines also have the disadvantages of high power consumption, poor safety, and inconvenient use.
