Sewing machine pneumatic lifting electronic mop mechanism and control method thereof

Abstract

The invention relates to the technical field of sewing, in particular to a sewing machine pneumatic lifting electronic mop mechanism and a control method thereof. The mechanism is simple in structure,components are simplified, the biasing force exerted on the mechanism is reduced, the service life of a double-acting cylinder and a linear guide assembly is favorably prolonged, needle loss during sewing can be prevented, the mop wheel lifting opportunity can be controlled, and the mop jam between the mop wheel and a presser foot is better relieved. The mechanism comprises an integrated pneumatic lifting and pressing assembly, the integrated pneumatic lifting and pressing assembly and a vertical guiding adjustment assembly are fixed to a main body fixing plate by screw connection, an electronic mop execution assembly is fixedly connected to a connecting support of the vertical guiding adjustment assembly, the transmitting end of a photoelectric detector is arranged between a mop wheel assembly in an electronic mop execution assembly and the sewing machine presser foot, and the receiving end of the photoelectric detector is disposed on the lower portion of the opposite sewing machinehead.

Description

technical field [0001] The invention relates to the field of sewing technology, in particular to a sewing machine pneumatic lifting electronic mop mechanism and a control method thereof. Background technique [0002] The lifting mechanism and the mop pressure applying mechanism of the current electronic mopping mechanism are different parts, and the lifting mechanism is lifted by spring rebound, and the cylinder only provides the function of stretching out to make the mopping wheel reach the mopping position; the motor of the current electronic mopping mechanism The pulley and the driven wheel are respectively installed on two plates, and the tension of the synchronous belt is also tensed by increasing the separation distance between the two plates. Therefore, the structure of the mechanism is complex, the parts are numerous, and the cost is high, which cannot meet the needs of low-end customers. And at present, when the traditional electronic mop mechanism is running at a ...

AI Technical Summary

Problems solved by technology

Therefore, the structure of the mechanism is complicated, the parts are numerous, and the cost is high, which cannot meet the needs of low-end customers.

Moreover, when the current traditional electronic mop mechanism is running at a relatively high speed, due to the single supporting force of the driven shaft and the narrow width of the timing belt, it is easy to cause the breakage of the driven shaft and the timing belt; , the movement is not smooth enough during operation, the response of the mop wheel mop is not timely enough, and the phenomenon of needle drop during sewing is reduced
