Abstract

A bobbin winding device on bed of the industrial bed joints sewing machine comprises an installation board, a winding axle, a drive gear for driving the winding axle to rotate, a friction wheel and an on-off mechanism which impels the friction wheel going away from the drive wheel and consists of a camshaft, a can, a handle, a control board and a swinging shaft seat. When length of the thread for sewing reaches a set value, the on-off mechanism drives the winding shaft to break away from the drive wheel, ensuring a free set of bobbin winding thread. The bobbin winding device is convenient in operation and even in winding; and the loosen status of the thread is adjustable.

Description

Shuttle peg winding device on the industrial sewing Sewing machines

The utility model relates to a kind of Winder, the shuttle peg winding device of using on the particularly common high-speed industrial sewing machine for covering chain stitch head.

In existing high-speed industrial sewing machine for covering chain stitch, generally do not have shuttle peg winding device, need other configure dedicated shuttle peg winding device during use, and be installed on the head of sewing machine wheel below, when motor rotates by taking turns on the belt drives Sewing machines, drive bobbin winoler, make shuttle peg winding.Because bobbin winoler separates with head, need the professional to install when the user uses, otherwise do not reach satisfied coiling effect, and also need in the use to carry out auxiliary operation with hand, inconvenient operation, and the ball of string malalignment of coiled are loose.

The purpose of the utility model is to provide a kind of and is fixed on the head platen, and is easy to operate, and coiling is even, all adjustable shuttle peg winding device of coiling amount, elasticity.

The technical solution of the utility model is such: it comprises installing plate, be contained in the roll on the installing plate, be fixed on the roll lower end and have the friction wheel that friction is enclosed, be contained in drive relative on the arbor and be contained in the clutch of stirring mutual transmission between friction wheel and the drive on the installing plate with friction wheel.Described clutch is separately fixed at the handle and the cam of camshaft upper/lower terminal by the camshaft that is contained on the installing plate, be subjected to the control panel that cam stirs and swing axle bed and be contained in control panel and the swing axle bed between back-moving spring form.Roll passes the swing axle bed, and an end of control panel and swing axle bed is coaxial to be fixed on the installing plate by activity, and control panel is having the camber line groove in the centre position of rail-engaging mark mutually with cam, and when this groove touched mutually with cam, drive touched mutually with friction wheel.When handle was dialled to roll, camshaft drives cam moved to right control panel, swing axle bed, and the friction wheel that promotes the roll bottom touches combination mutually with drive, thereby drove the roll rotation, and empty peg or spindle gets final product automatic winding.

In empty shuttle peg winding process, peg or spindle thickens, and handle leaves roll gradually, simultaneously, drives cam and leaves the control panel groove; When shuttle peg winding reached the precalculated position, cam departed from groove under the effect of handle and back-moving spring, and at this moment, control panel and swing axle bed drive friction wheel and break away from drive, and roll stops operating, and coiling stops, thereby has reached the purpose of automatic winding.

The utility model also can be adorned a wire clipping component of regulating the coiling degree of tightness on deck plate; This wire clipping component is made up of the line plate excessively, clamp dish, the adjustment nut that are fixed on the tailor's tack excessively on the deck plate and be enclosed within successively on the tailor's tack.

Below in conjunction with embodiment shown in the drawings the utility model is described in further detail.

Fig. 7 is the wire clipping component cutaway view.

Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, shuttle peg winding device on the industrial sewing Sewing machines comprises installing plate 10, be contained in the roll 1 on the installing plate 10, be fixed on roll 1 lower end drive 2 relative and stir the clutch of friction wheel 3 and drive 2 clutches on being with the friction wheel 3 of friction circle 19 and being contained in arbor with friction wheel 3.

Installing plate 10 is the garden shape, which is provided with two holes of running through for the camshaft 15 in roll 1 and the clutch respectively, garden.Have single order protruding in the middle of the roll 1, protruding bottom, rank is run through on the at one end movable swing axle bed 17 that is fixed on the installing plate 10, and roll 1 is equipped with the lock core spring 13 of coiling axle pad 12 and fastening peg or spindle respectively being positioned at installing plate 10 plate face tops.

Clutch comprises camshaft 15, with the handle 7 of screw clamping in camshaft 15 upper ends, spiral is at the cam 4 of camshaft 15 bottoms, one end is fixing with pivot pin 15 and jump ring 18, and make its control panel 16 and swing axle bed 17 around the axle swing, be connected with extensive position spring 20 between the reference column 10a on control panel 16 and swing axle bed 17, the installing plate 10 respectively.Have groove 28 in the middle of the control panel 16, and touch mutually with cam 4, groove is made arc shaped for 28 mouthfuls, is convenient to cam 4 and rotates.Be screwed adjustable plate 6 on the handle 7, the centre of adjustable plate 6 has the camber line hole, is installed with screw 11 on the camber line hole, and screw 11 spirals are on handle 7; Adjustable plate 6 is the closer to bobbin 1, and the shuttle peg winding amount is few more.After empty peg or spindle is contained in roll 1, handle 7 is relied on the sky peg or spindle, camshaft 5 and cam 4 rotate thereupon, and drive control panel 16 swings; And control panel 16 drives rolls 1 and the friction wheel 3 fixed on it contact with drive 2, and at this moment, cam 4 embeds in the groove 28 of control panels 16, locks drive connection between friction wheel 3 and the drive, guarantees roll 1 normal operation, referring to Fig. 6.Start Sewing machines work, can wind the line.When peg or spindle after the full dimension of setting, handle 7 separates gradually with peg or spindle axle 1, and drives cam 4, breaks away from control panel 16 grooves 28, at this moment, back-moving spring 20 is upspring control panel 16, friction wheel 3 breaks away from drive 2, coiling stops.

Referring to Fig. 7, the utility model also comprises wire clipping component 9 and blade 8.Wire clipping component 9 is to guarantee shuttle peg winding degree of tightness and uniform a kind of device, and it crosses line segment nail 24 by what be fixed on deck plate, is fixed in crossing line plate 26, clamp dish 22, spring 23, adjust nut 25 and form on the tailor's tack 24 successively.Cross line plate 26 and be angle square shape, position relative with clamp dish 22 on it has wire guide 27, as long as nut 25 is adjusted in rotation, can adjust the clamping degree of clamp dish 22, thereby regulates degree of tightness, the uniformity coefficient of coiling.Blade 8 is to be used for and will behind the shuttle peg winding line between peg or spindle and the wire clipping component 9 to be cut off so that twine next peg or spindle.

When the utility model is installed, only the head outside is exposed at roll 1 position on top, other rotatable parts do not contact with the operator all in head inside, therefore can not bring injury to operator's work.Because the utility model has improved original Sewing machines Winder, thereby makes its structure more reasonable, not only breaks away from manual operations, realize automatic winding, clutch, and the ball of string behind full peg or spindle have the certain power of holding tightly and marshalling.
