Description

Verticle circular disk sewing machine

The utility model relates to a kind of Z ₄-35L vertical disc sewing machine, or rather, it belongs to knitting stitching mechanical field.

Existing Z ₄The design feature of-35 type disk sewing machines and the kind of drive are as shown in Figure 1, its operation principle is, by belt pulley 1 input power, little cam 18 and inside and outside grooved cam 17 that drive is contained on the camshaft 3 rotate, and drive the worm screw 11 and the eccentric wheel 19 that are contained on the worm shaft 20 by a pair of bevel gear 2 simultaneously and rotate.Worm screw 11, inside and outside grooved cam 17, little cam 18, eccentric wheel 19 are not to be contained on the axle, but are contained in respectively on two axles.Can further know from accompanying drawing 1: the rotation of 1. little cam 18 makes centering block shift fork 7 reciprocating by cam link 14, thereby makes executing agency's pin arm (not drawing among the figure) reciprocating; When 2. inside and outside grooved cam 17 rotated, by inner rocker mechanism 5 inside connecting rods 6, shank shift fork 4 back and forth rotated bolster 16, thereby realized moving up and down of executing agency triangle bearded needle (not drawing among the figure); When 3. inside and outside grooved cam 17 rotates,, make outside connecting rod 9 reciprocating by outer rocking bar 8; 4. worm screw 11 drives worm gear 10 rotations, and the little tooth axle 12 of worm gear drives rotates, and by gears engaged, thereby executing agency's row dish 21 is rotated; 5. the rotation of eccentric wheel 19 drives eccentric ratio 15 reciprocating motions, thereby makes 13 reciprocating motions of pin arm centering block realize the reciprocal rotation of executing agency's pin arm.The horizontal disc sewing machine of this structure, vibrate bigger, the high-grade meticulous stitching of incompatibility, the problem that exists production efficiency further to improve.

The purpose of this utility model is exactly the above-mentioned deficiency at existing horizontal disc sewing machine, carries out reasonable structural design, thereby improves the suture quality of fabric, enhances productivity.

The purpose of this utility model is achieved in that

Worm screw, helical gear, inside and outside grooved cam, little cam and eccentric wheel are contained on the axle successively, rather than are contained in respectively on two axles.The cone pulley that is contained on the motor shaft is fixed on the electric machine support with frictional disk mutual friction mutually, spring one end, and the other end is fixed on the support, makes cone pulley near frictional disk, and the variable motion of frictional disk is rotated by a pair of gear driven helical gear.

No matter vertical garden dish sewing machine is that helical gear is able to gear motion with any power input, helical gear, worm screw, inside and outside grooved cam, little cam, eccentric wheel are installed on the axle.Pass course transmits, and makes executing agency's work.

The utility model is compared with existing type, the action of executing agency is consistent, the design but input and the transmission means of motion make a big improvement, make the utlity model has rational in infrastructure, simple, vibrate less, characteristics such as adapt to high-grade meticulous stitching, production efficiency is higher, and is easy to use.

The utility model will be further described below in conjunction with accompanying drawing:

Fig. 1 is existing horizontal disc sewing machine structural representation;

Fig. 2 is a front view of the present utility model;

Fig. 3 is a vertical view of the present utility model;

Fig. 4 is a left view of the present utility model;

Fig. 5 is the front view of the utility model when power is directly imported;

Fig. 6 is the A-A profile among the utility model Fig. 2;

Fig. 7 is that B among the utility model Fig. 2 is to view;

Fig. 8 is that C among the utility model Fig. 2 is to view;

In the drawings, 1 is belt pulley; 2 is bevel gear; 3 is camshaft; 4 is the shank shift fork; 5 is inner rocker; 6 is inside connecting rod; 7 is the centering block shift fork; 8 is outer rocking bar; 9 is outside connecting rod; 10 is worm gear; 11 is worm screw; 12 is little tooth axle; 13 is pin arm centering block; 14 is cam link; 15 is eccentric ratio; 16 is the bearing axle; 17 is inside and outside grooved cam; 18 is little cam; 19 is eccentric wheel; 20 is worm shaft; 21 is dials; 22 is pedal; 23 is connecting rod; 24 is motor; 25 is cone pulley; 26 is the drag ring dish; 27 is pinion; 28 is gear wheel; 29,30 is helical gear; 31 are holder clothing dish; 32 is head part; 33 is frame; 34 is guide rod; 35 is main shaft; 36 is executing agency; 37 is power input shaft; 38 is outer rocking bar; 39 is outside connecting rod; 40 is lever; 41 is connecting rod; 42 is the bearing axle; 43 is the shank shift fork; 44 is the centering block shift fork; 45 is cam link; 46 is pin arm centering block; 47 is eccentric ratio.

From Fig. 2, Fig. 3, Fig. 4, Fig. 6 as can be known: worm screw 11, helical gear 30, inside and outside grooved cam 17, little cam 18 and eccentric wheel 19 are contained on the axle successively, being achieved as follows of executing agency's motion: the rotation of inside and outside grooved cam 17 is on the one hand by lever 40, connecting rod 41, shank shift fork 43 has been realized the reciprocal rotation of bearing axle 42, make outside connecting rod 39 reciprocating by outer rocking bar 38 on the other hand, the triangle bearded needle is back and forth moved up and down and back and forth rotation.

As can be seen from Figure 7: the rotation of little cam 18 has realized the reciprocating motion of centering block shift fork 44, thereby makes executing agency's pin arm reciprocating.

As can be seen from Figure 8: the rotation of eccentric wheel 19 can make eccentric ratio 47 reciprocally swingings realize the reciprocal rotation of executing agency's pin arm.

As can be seen from Figure 2: its motion input mode of the utility model adopts the stepless speed regulation structure.The realization of stepless speed regulation is the mutual friction mutually that is adjusted in cone pulley 25 and drag ring dish 26 on 24 in the motor by pedal 22, spring one end is fixed on the electric machine support, the other end is fixed on the support, making drag ring dish 26 obtain different speed changes rotates, drive

helical gear

29,30 and rotate by a pair of pinion 27, gear wheel 28 then, finally make dials 21 realize infinitely variable speeds.

Fig. 5 is installed on the axle for helical gear 30 and worm screw 11, inside and outside grooved cam 17, little cam 18, eccentric wheel 19, when power is directly imported, from driven input shaft 37 power is directly passed to

helical gear

29,30, the rotation of inside and outside grooved cam 17 is on the one hand by lever 40, connecting rod 41, shank shift fork 43 is realized the reciprocal rotation of bearing axle 42, on the other hand, make outside connecting rod 39 reciprocating, the triangle bearded needle is back and forth moved up and down and reciprocating motion by outer rocking bar 38.
