Household hand-held small button-sewing machine based on four-bar linkage mechanism

Abstract

The invention provides a household hand-held small button-sewing machine based on a four-bar linkage mechanism. The machine comprises a left housing, sewing machine lines, sewing machine line sleeve shafts, an Arduino microcontroller, a rocking rod-connecting rod rotating shaft, a trigger, a connecting rod, a crank connecting rod shaft, a crank cam, an inner hexagon screw, a cylinder reciprocatingpiston fixing rack, a stepping motor shaft, a clothes fixing head, an eccentric stepping motor fixing rack, an eccentric stepping motor, an eccentric stepping motor shaft, a coupler, a winding planeboard, a four-hole button, a lead screw nut, a lead screw, a button-sewing needle, a driven bevel gear, a wafer magnet, a distance-adjusting motor shaft, a right half of a cylinder reciprocating piston, a left half of the cylinder reciprocating piston, a stepping motor, a battery box, batteries, a reset spring, a trigger rotary shaft, a left housing, a housing fixing nut, a battery box end cover,a crescent-shaped connecting board and a rotary bolt shaft. The household hand-held small button-sewing machine can effectively avoid complicated procedures during a button-sewing process such that the machine becomes a device for sewing buttons with high automation degree for ordinary people.

Description

Technical field: [0001] The invention relates to an automatic button-making device, in particular to a small-sized button-making device which can automatically complete the button-making steps with simple operation. Background technique: [0002] In today's era, clothing is indispensable in people's daily life. Buttons are an integral part of many garments. In the face of high-frequency usage, the breakage of the rope fixing the buttons and the loss of the buttons caused by this have always troubled us. If manual button sewing requires certain skill training, most young people cannot be qualified for this kind of work. And the automatic device of existing button is all the large-scale equipment that garment processing factory uses, and the price is expensive and is not suitable for household. These circumstances make sewing buttons a time-consuming and labor-intensive task. [0003] Along with the continuous improvement of people's functional requirements for button mend...

AI Technical Summary

Problems solved by technology

However, the existing button-making tools generally have a low degree of automation and a low degree of adaptability to various four-hole buttons. There are only simple mechanical auxiliary units without control units, so only simple auxiliary functions can be realized, but automatic button making cannot be realized. function of
