Abstract
The utility model provides an improvement on a gearing structure for a sewing machine, which can simplify a gearing structure, and can provide speed change, having easy maintenance. The gearing structure for the sewing machine is mainly composed of a primary gear box and a secondary gear box; the primary gear box is mainly driven by a drive belt for a motor, when the speed of the motor is reduced, and the primary gear box provides power for the secondary gear box; the secondary gear box is engaged with the primary gear box through the meshing gear, and a molding wheel on the secondary gear box can respectively control the moving distance of a knitting face in the transverse and longitudinal directions to knit various patterns; the meshing gear size of the primary gear box and the secondary gear box can be changed for the speed change of the secondary gear box, and the knitting pattern has multiple variability.
Description
The utility model relates to a kind of improved sewing machine drive mechanism, refers to a kind of sewing machine driving structure improvement that changes braiding speed especially, and it has easy construction and installation, reduces the fault chance, and tool effect easy to repair.
The purposes of sewing machine is mainly bed gown, jacket, bedcover, mattress, handbag, the snow clothing, footwear, children's garment, the braiding of cloth cover such as pram suit and Chair cover for automobile, its scope of application is quite extensive, and sewing machine commonly used adopts single formula gear-box, motor belt directly drives this gear-box, the horizontal rotating shaft that reaches vertical gear and be connected in this gear of exporting again by the briquetting roller control of this gear-box, traversing to drive cloth cover reach and surface of second order, control the style of whole cloth cover braiding, because gear-box commonly used adopts single formula, its complex structure, maintenance is difficult for, and the braiding style is limited by gear-box directly, in some special braiding style occasions, its braiding speed can't change cooperation, and many inconvenience are arranged in the use.
The purpose of this utility model is to provide a kind of improved sewing machine drive mechanism, and it has is convenient to the effect assembling, dismantle, make, the drive mechanism of sewing machine is simplified, and can be changed the meshing gear size, to change the speed of braiding style.
Sewing machine drive mechanism of the present utility model, it is characterized in that: it comprises a main-gear box and a gear-box, side is connected with a travelling gear outside the master gear, the direct transmission of this gear through final drive shaft interlock main-gear box and after slowing down, the top of main-gear box is established a bent plate in addition, can screw be fixed on it by meshing gear, makes the gears engaged on meshing gear one end and the main-gear box, the outward extending linked gear engagement of the other end and time gear-box conducts to time gear-box with power.
For reaching above-mentioned purpose, sewing machine driving structure improvement of the present utility model, after it is characterized in that power transmission shaft is driven by motor belt, its tail end connects a main-gear box, this gear-box is pure to be designed for reducing rotating speed and increasing torsion, side is provided with the gear of always accepting the main-gear box transmission outside the gear-box, the gears engaged that this gear is connected with time gear-box by a meshing gear, reach via main-gear box and drive time gear-box, simplify the structure of main-gear box indirectly, and make it have the function of conversion rate.
Of the present utility model is to utilize separating of main-gear box and inferior roller box on the other hand, and gear box structure is simplified, so that maintenance and installing/dismounting, and reduce failure situations.
Other purpose of the present utility model, advantage and feature can be obtained further to understand by the detailed description and the cooperation diagram of following preferred implementation.
Fig. 1 is the transmission diagram of the utility model drive mechanism;
Fig. 2 is the outside drawing of the utility model drive mechanism;
Fig. 3 is the action schematic diagram of the utility model drive mechanism;
Fig. 4 is the outside drawing of the utility model sewing machine;
Fig. 5 is a preferred embodiment figure of the present utility model.
Consult Figure 1 and Figure 2, sewing machine drive mechanism of the present utility model, mainly form by a main-gear box 1 and time gear-box 2, one of main-gear box 1 side is connected to main shaft 10, this main shaft 10 is also directly driven by motor belt 11, to main-gear box 1, the power of motor is after main-gear box 1 slows down, by travelling gear 12 outputs that are connected in main-gear box 1 outside with power transmission; In addition, main-gear box 1 top is provided with one and protrudes bent plate 13, and this bent plate 13 can be used screw 14 lockings one rocking bar 30, and constant mesh gear 3 is on this bent plate 13; And a side of inferior gear-box 2 is provided with a driven gear 20, and a meshing gear 21 is established in the top of this gear 20, by outrigger shaft 23 No. inferior gear-box 2 transmissions is extended out on the gear 22; Utilize 12 engagements of meshing gear 3 one ends and gear, the other end and travelling gear 22 engagements, make motor power can through gear 12 to meshing gear 3 to gear 22,21 to the driven gear 20 of inferior gear-box 2 to inferior gear-box 2, turn round to drive entire machine.
Please cooperate and consult Fig. 2 and 3, inferior gear-box 2 is after main-gear box 1 drives, by the briquetting roller 24 on the inferior gear-box 2, rotate with control reach rotating shaft 25, the drive reach of weaving cotton cloth, on the other hand, inferior gear-box 2 is subjected to another briquetting roller 27 controls of the back side, moves to control traversing plate 26, the drive surface of second order is traversing, therefore when braiding, knitting needle be subjected to connecting rod 15 pullings to be up and down repetitiousness moves, again by the briquetting roller 24 in inferior gear-box 2 outsides, whole surface of second order reach of 27 controls or transverse moving left and right, to knit out the style of setting, and change briquetting roller 24,27 shape can change the style of braiding, and the one preferred embodiment as shown in Figure 5.
Utilize said structure, the main transmission system of the utility model is separated, and exposes to outside the gear-box, the structure of main-gear box 1 and time gear-box 2 not only be simplified separation, and its fabrication and installation is easy, the fault probability is few, maintenance also becomes simple and easy, and like existing overall gear box structure, all gears all are not sealed in the case, complex structure, and there is arbitrary gear to damage, promptly need puts in order assembling and dismantling and change maintenance, truly have very much progress using and keep in repair the utility model.
On the other hand, main-gear box 1 and time gear-box 2 are connected with a meshing gear 3, this meshing gear 3 is fixed on the bent plate 13 with screw 14, therefore its dismounting and change is quite easy, as change the diameter of meshing gear 3, can change the main transmission speed of time gear-box 2, and then change the style of braiding, therefore, the utility model and existing structure relatively have more the advantage of multiple braiding style.
In sum, sewing machine drive mechanism of the present utility model not only has and is convenient to the effect of assembling, keeping in repair, and reaching purpose actual easy to use, and its braiding speed is variable, makes the braiding style of sewing machine have more multiple variability.
