The specific embodiment
The utility model has disclosed a kind of computer quilting machine head, comprises thread take-up mechanism and presser foot device.Thread take-up mechanism is meant in forming the process of stitching, plays conveying, reclaims needlework and tightens up the mechanism of stitching effect.As depicted in figs. 1 and 2, the thread take-up mechanism of this preferred embodiment comprises needle bar crank 21 and the thread take-up tension lever 22 that is driven by head belt shaft 20, and described head belt shaft 20 passes needle bar crank 21, and drive needle bar crank 21 rotates together.Bearing of thread take-up tension lever 22 dependence pivot prejudicially is arranged on the needle bar crank 21.
Line-choosing connecting rod 23 and thread take-up crank 25 have been connected on the described thread take-up tension lever 22.Wherein, first end of line-choosing connecting rod 23 is fixed in the head by hinge axis 24 pivots, and line-choosing connecting rod 23 can be rotated around hinge axis 24 pivots.Second end pivoting of line-choosing connecting rod 23 is arranged on the thread take-up tension lever 22.On thread take-up tension lever 22, be provided with a thread take-up crank 25 with coaxial bearing.Thread take-up crank 25 can lean on six sides to be fixed on the thread take-up tension lever 22, and thread take-up crank 25 and thread take-up tension lever 22 are made one in this preferred embodiment.
Have an end of a shank connecting rod 26 to be socketed on the projection on thread take-up crank 25 surfaces, the other end is fixed with a slide block 27, and this slide block 27 slides in the guide rail 28 that is fixed in head inside.Described shank connecting rod 26 is socketed with a shank joint 29 at the opposite side that slide block 27 is set, and is provided with shank 30 in this shank joint 29.
After head belt shaft 20 rotates, drive needle bar crank 21 and rotate, thread take-up crank 25 and thread take-up tension lever 22 are rotated around head belt shaft 20; Simultaneously because the effect of hinge axis 24 makes line-choosing connecting rod 23 rotate around hinge axis 24.Because the off-centre setting of thread take-up crank 25 on needle bar crank 21, rely on the principle of crank block, the displacement that the rotation of needle bar crank 21 can make thread take-up crank 25 and shank connecting rod 26 produce axial direction, and slide block 27 is slided in guide rail 28, so just drive shank joint 29 and the axial displacement of shank 30 generations, thereby begin to make material.
The needle bar stroke of prior art is 36mm, is a that stroke is grown in the domestic head.This preferred embodiment changes the parameter of shank connecting rod, thread take-up crank and line-choosing connecting rod, makes needle bar stroke be increased to 45mm from 36mm.So just can reduce eedle in the time that plants, move the deformation effect that eedle is produced thereby improve to plant, the improvement amplitude is (45-36) ÷ 36=25%, if planting mobile 1mm originally in other words, just have only 0.75mm now, simultaneously, because the increase of needle bar stroke, the Ci Bu of eedle speeds up, penetration capacity increases, and the thick ability of seam of head has also been strengthened, and this also is very important, because mainly to stitch a quilt cover on, great majority are thick material to quilting machines; Both reduce the pin that draws that plants so increase the needle bar stroke of head, strengthened the thick ability of seam of head again.
Introduce presser foot device of the present utility model below, as shown in Figure 3 and Figure 4, include presser feet power transmission shaft 1 and power transmission shaft axle bed 2.Described presser feet power transmission shaft 1 is rotated and passes the power transmission shaft axle bed 2 that is fixed on head inside by 20 drivings of head belt shaft.Fig. 3 has disclosed a kind of movable presser foot device, removably is arranged with movable presser foot device on described presser feet power transmission shaft 1, and described movable presser foot device can drive presser feet 12 and produce axially-movable with shank 30; Fig. 4 has disclosed a kind of fixing presser foot mechanism, removably is connected with fixing presser foot mechanism on the described power transmission shaft axle bed 2, and the controlled pin 12 of neutralizing of described fixing presser foot mechanism is pressed on the material surface regularly; Described movable presser foot device and fixing presser foot mechanism replace dismounting and use.
As shown in Figure 3, described movable presser foot device comprises presser feet fork 3, connecting rod 5, presser bar bar cover 7 and presser bar 8; First end of described presser feet fork 3 connects on presser feet power transmission shaft 1, and its second end is connected in second end of connecting rod 5; First end of described connecting rod 5 is connected on the presser bar bar cover 7, is provided with presser bar 8 in the described presser bar bar cover 7.
Further, second end of second end of described presser feet fork 3 and connecting rod 5 is pivotally connected by fork bearing pin 4; First end of described connecting rod 5 and presser bar bar cover 7 are pivotally connected by pin 6.
When presser feet power transmission shaft 1 rotates, can drive presser feet fork 3 and produce swing, second end of drivening rod 5 also produces swing simultaneously, and then first end of drivening rod 5 produces axial moving, thereby make presser bar bar cover 7 and presser bar 8 also produce axial moving, promptly presser feet 12 can bob in quilting.
As shown in Figure 4, described fixing presser foot mechanism comprises compressor arm spring guide pillar 9, compressor arm spring 10, compressor arm saddle 11, presser bar bar cover 7 and presser bar 8, described compressor arm spring guide pillar 9 removably is fixed on the power transmission shaft axle bed 2, and pass compressor arm spring 10 and compressor arm saddle 11 and be connected in presser bar bar cover 7, be provided with presser bar 8 in the described presser bar bar cover 7.
Further, the height of described presser bar 8 and presser feet 12 is by the look nut control that is connected on the compressor arm spring 10.
Movable presser foot device in the utility model makes presser feet and eedle by certain relation, and bob when quilting when making thick material, can solve the folded phenomenon of lining when making cross track like this; But when making, use the fixing presser foot mechanism of not jumping, can improve the sewing quality of suture than thin material.In the process of changing, only need disassemble presser feet fork 3 from presser feet power transmission shaft 1, connecting rod 5, presser bar bar cover 7 and presser bar 8 are removed together, then the compressor arm spring guide pillar 9 of fixing presser foot mechanism, compressor arm spring 10, compressor arm saddle 11, presser bar bar cover 7 and presser bar 8 are installed on the power transmission shaft axle bed 2 and get final product, convenient and reliable, have very strong practical value.
The utility model still has multiple concrete embodiment, and all employings are equal to replacement or equivalent transformation and all technical schemes of forming, all drop within the claimed scope of the utility model.
