Abstract
The utility model belongs to the technical field of sewing devices, and particularly relates to an automatic speed regulation device of a sewing machine. A pressing rod guide frame is arranged outside the upper end of a pressing rod in a sleeved mode, the pressing rod axially moves according to cloth, a sensor A is fixedly arranged on a side face of the pressing rod guide frame, a sensor B which corresponds to the sensor A in position is arranged on a face plate or a machine head, vertical displacement of the sensor A is sensed by the sensor B, and the sensor A and the sensor B are both connected with a controller. The sensor A and the sensor B act on each other, the pressing rod can move up and down along with the cloth to drive the sensor A to move up and down in the sewing process when the thickness of the cloth is not uniform, the sensor B automatically controls the sewing machine to change the speed when sensing the distance difference of the position of the sensor A, and the automatic speed regulation device of the sewing machine is high in intelligent degree, efficient, accurate, compact in structure, easy and convenient to install, good in stability and suitable for the sewing machine.
Description
Technical field:
The utility model belongs to sewing device technical field, refers in particular to a kind of automatic speed governing device of Sewing machines.
Background technology:
Sewing machines, in the process of making, there will be the inhomogeneous situation of fabric thickness, and cloth is thick, needs to accelerate.In prior art, speed governing is to control by pedal, and pin is stepped on and weighed a bit, can accelerate.Manual control acceleration-deceleration, exists: complex structure, to install loaded down with trivial detailsly, and structural stability is poor, high in cost of production defect.
Summary of the invention:
The purpose of this utility model be to provide a kind of intelligent degree high, can automatically carry out the automatic speed governing device of the Sewing machines of speed governing according to the thickness of cloth.
The utility model is achieved in that
A kind of automatic speed governing device of Sewing machines, according to being set with presser bar spring bracket outside the upper end of the axially movable depression bar of cloth, on one side of presser bar spring bracket, be installed with A inductor, on panel or on head, be provided with the B inductor corresponding with A sensor location, the upper and lower displacement of B inductor induction A inductor, described A inductor and B inductor are all connected with controller.
On above-mentioned presser bar spring bracket, be provided with screwed hole, be provided with corresponding installing hole on A inductor, screw is screwed onto through the installing hole on A inductor in the screwed hole of presser bar spring bracket A inductor is fixed on presser bar spring bracket.
Above-mentioned A inductor, B inductor interval arrange, and the distance between A inductor, B inductor is 0.2-0.8 millimeter.
Above-mentioned A inductor, the distance between B inductor are 0.5 millimeter.
The utility model compared to existing technology outstanding advantage is:
The A inductor that the utility model arranges, B inductor interacts, in the process of making, the uneven thickness of cloth, depression bar can move up and down along with cloth, drives A inductor to move up and down, the position of B inductor induction A inductor produces range difference, automatically control Sewing machines speed change, intelligent degree is high, efficient, accurately, compact conformation, simple installation, good stability.
Accompanying drawing explanation:
Fig. 1 is that the utility model is arranged on the schematic diagram on Sewing machines;
Fig. 2 is that inductor A of the present utility model is installed in the schematic diagram on presser bar spring bracket.
The specific embodiment:
With specific embodiment, the utility model is further described below, referring to Fig. 1-2:
A kind of automatic speed governing device of Sewing machines, outside the upper end of the axially movable depression bar 10 according to cloth, be set with presser bar spring bracket 20, on one side of presser bar spring bracket 20, be installed with A inductor 30, on panel or on head 40, be provided with the B inductor 50 corresponding with A inductor 30 positions, the upper and lower displacement of B inductor 50 induction A inductors 30, described A inductor 30 and B inductor 50 are all connected with controller.
On above-mentioned presser bar spring bracket 20, be provided with screwed hole, be provided with corresponding installing hole on A inductor 30, screw 60 is screwed onto through the installing hole on A inductor 30 in the screwed hole of presser bar spring bracket 20 A inductor 30 is fixed on presser bar spring bracket 20.
Above-mentioned A inductor 30, B inductor 50 intervals arrange, and the distance between A inductor 30, B inductor 50 is 0.2-0.8 millimeter, 0.5 millimeter of operated by rotary motion.
Operation principle of the present utility model:
One end of depression bar 10 is sleeved on outside one end of pressure regulation guide rod 70, the other end is provided with presser feet, the other end of pressure regulation guide rod 70 is connected with pressure regulating screw 80, outside pressure regulation guide rod 70 between pressure regulating screw 80 and depression bar 10, be set with back-moving spring 90, the power that pressure regulating screw 80 regulates back-moving spring 90 to reset, when the thickness of cloth increases, presser feet drives on depression bar 10 and moves, back-moving spring 90 compressions, being arranged on presser bar spring bracket 20 on depression bar 10 and A inductor 30 moves on all, now, the displacement of B inductor 50 induction A inductors 30, send order to controller, controller is controlled Sewing machines degree of adding, when the reduced thickness of cloth, back-moving spring 90 moves down depression bar 10, A inductor 30 moves down, the displacement of B inductor induction A inductor 30, send order to controller, controller is controlled Sewing machines degree of subtracting.
Above-described embodiment is only one of preferred embodiment of the present utility model; not with this, limit practical range of the present utility model; therefore: all equivalences of doing according to shape of the present utility model, structure, principle change, within all should being covered by protection domain of the present utility model.
