Abstract

The utility model relates to a winding mechanism of an embroidering machine controlled by a computer. The utility model is characterized in that the upper position and the lower position are respectively connected with a cam A and a cam B, and peach-shaped projecting part of the cam B is arranged in a notch corresponding to the cam A. The upper end of the cam A is provided with a shaft and shuttle spindles sheathed on the shaft, and the cam A is provided with a wire plate. After the shuttle spindle is circled with the bottom wire, a handle is pressed via the wire plate to cause the cam A and the cam B to separate for completing winding working. The utility model makes use of the self dynamic force of an embroidering machine and uses a cam type clutch structure. A motor and an optical coupling control mechanism are removed. The utility model has the advantages of low cost, reliable working, and long service life.

Description

Winding mechanism

The utility model relates to a kind of computer embroidering machine winding mechanism.

Winding mechanism is the indispensable parts of computer embroidering machine around bottom line.Existing winding mechanism adopts the brush motor-driven of 24V direct current, and the shuttle peg winding amount is controlled by optocoupler.Yet there is some defective in the winding mechanism of said structure form: 1, manufacturing cost height, is unfavorable for the low-cost design of computer embroidering machine trend by about more than 300 yuan.2, the motor of electric system and optocoupler control section fault rate height, poor reliability, the maintenance rate height brings inconvenience to the user.People's technical scheme that addresses the above problem that waits in expectation produces as early as possible.

The utility model is to realize that cost is low, the purpose of reliability height and long service life.

In order to achieve the above object, of the present utility model being characterised in that a: mainboard that is connected with base is arranged, mainboard passes through locating shaft respectively, connecting axle connects cam A up and down, cam B, the peach shape projection of cam B is contained in the corresponding breach of cam A, and the main shaft in axle sleeve and the axle sleeve is housed in the axis hole of cam A upper end, and main shaft one end is set with rubber tire; The main shaft other end is equipped with back-up ring and peg or spindle, connects a full strip by axle on cam A, and the adjustment screw is equipped with in bottom surface, full strip lower end, and a springboard spring one end is contained on the full strip; The other end is contained on the little axle, and an extension spring one end is connected on the cam A; The other end is contained on the mainboard, one spoonful of shape handle, and its lower end is sleeved on the connecting axle.

The utility model compared with prior art has the following advantages and good effect: 1, winding mechanism utilizes embroidery machine self power transmission, saved motor, adopt the clutch of cam-type structure, save former optocoupler controlling organization, so, its cost greatly reduces, and about 40-50 unit is the 1/5-1/6 of former agency cost approximately.2, reliable operation, long service life, fault rate greatly reduces.

Fig. 2 is the A-A cutaway view of Fig. 1;

Fig. 3 is the D-D cutaway view of Fig. 1.

1, rubber tire; 2, nut; 3, axle sleeve; 4, cam A; 5, interior tightening; 6, back-up ring; 7, peg or spindle; 8, locating shaft; 9, cam B; 10, connecting axle; 11, screw; 12, packing ring; 13, base; 14, back-up ring; 15, interior tightening; 16, back-up ring; 17, interior tightening; 18, handle; 19, nut; 20, adjust screw; 21, full strip; 22, little axle; 23, main wheel; 24, screw; 25, extension spring; 26, mainboard; 27, springboard spring; 28, main shaft.

Referring to Fig. 1, Fig. 2, Fig. 3, one mainboard 26 that is connected with base 13 is arranged, mainboard 26 is respectively by locating shaft 8, connecting axle 10 connects cam A4 up and down, cam B9, the peach shape projection of cam B9 is contained in the corresponding breach of cam A4, and the main shaft 28 in axle sleeve 3 and the axle sleeve is housed in the axis hole of cam A4 upper end, and main shaft 28 1 ends are set with rubber tire 1; Main shaft 28 other ends are equipped with back-up ring 6 and peg or spindle 7, connect by little axle 22 on cam A4

The full strip 21 of shape, bottom surface, full strip 21 lower end are equipped with adjustment screw 20, one springboard springs 27 1 ends and are contained on the full strip 21; The other end is contained on the little axle 22, and an extension spring 25 1 ends are connected on the cam A4; The other end is contained on the mainboard 26, one spoonful of shape handle 18, and its lower end is sleeved on the connecting axle 10.

During work, handle 18 is shifted the B position onto from the C position, and cam A4 is upwards rotated, rubber tire 1 is pressed against on the main wheel 23, rotates with peg or spindle 7 thereby drive rubber tire 1, peg or spindle 7 begins coiling, when bottom line during around full peg or spindle 7, the adjustment screw 20 on full strip 21 bottom surfaces is pressed on the handle 18, makes handle 18 get back to the C position, at this moment, the peach shape of cam B9 partly breaks away from cam A4 breach, and because of the effect of extension spring 25, cam A4 rotates simultaneously, set back, a working cycles finishes.
