Abstract
The utility model relates to a presser foot lifting mechanism of a quilter head, which orderly drives a transmission eccentric link following the rotation of an upper shaft by an eccentric wheel fixed on the upper shaft, and drives a front crank and a back crank which are fixedly connected as integration to swing with a swing lateral shaft. During the swing, the back crank orderly rotates a lifting connecting rod, a presser foot positioning block, a presser foot bar and a presser foot to carry out an up-down operation with a needle bar synchronously. When the bedding and clothing of different thickness are quilted by the presser foot of the utility model, the presser foot and the quilting material carry out up-down movement synchronously. The presser foot lifting mechanism of a quilter head has conspicuous advantages that the feeding and discharging of the material are convenient; the defects of plunger pin and broken needle caused by nonuniform thickness change and nonuniform pressure of the materials during the quilting can be avoided. The quality of the quilting work can be ensured, and the work efficiency can be improved.
Description
Affiliated technical field
The utility model relates to a kind of presser feet of Sewing machines, specifically a kind of presser feet elevating mechanism of quilting machines head.
Background technology
The presser feet of existing quilting machines head, on the presser feet straight-bar, be with stage clip and ghost nut and regulate the pressure that compresses material downwards, in case set up, this pressure substantially constant is constant, can not change with the material thickness, occurs drawbacks such as broken needle and bouncing pilotage in the quilting operation easily, this kind presser feet armrest is pulled lifting, use inconvenience, fault is many, and work efficiency is low.
Summary of the invention
Pull the operational inconvenience of presser feet lifting and be prone to faults such as bouncing pilotage, broken needle in order to overcome existing hand, the utility model provides a kind of presser feet that has with the synchronous automatic lifting of shank, downward every seam one pin of shank, presser feet compresses once automatically, it is reliable to make it thrust, input and output material is convenient, and sewing such as no bouncing pilotage, broken needle fault improves work efficiency.
The technical scheme in the invention for solving the technical problem is: the fixedly connected eccentric wheel of axle is connected movingly on an eccentric ratio and the quilting machines, the eccentric ratio other end be fixed on the rear crank of swing on the transverse axis and be connected movingly, the preceding crank that is fixed on the swing transverse axis other end is connected with presser bar movingly with lifting linking member, eccentric wheel is provided with the branch head screw of adjustment and fixed eccentric and last between centers phase place, has the slotted hole of wearing the adjustment screw of adjusting presser feet heave amplitude size on the rear crank.Axle rotation on quilting machines head during running, drive eccentric wheel, eccentric ratio successively, the rear crank that the eccentric ratio transmission fuses, swing transverse axis, preceding crank are swung simultaneously, preceding crank-swinging drives lifting linking member and presser bar moves up and down, regulate eccentric wheel and the last phase place that the mutual alignment concerns by the branch head screw on the eccentric wheel, presser bar and shank are moved up and down synchronously; Adjust the upper-lower position height of adjustment screw in the rear crank slotted hole, can adjust the size of presser bar heave amplitude and thrust.
Good effect of the present utility model is that presser feet is to stressed size of material and presser bar height adjustable size, when making the quilting operation presser feet and eedle synchronously about, synchronous input and output material, pressure is reliable, easy to use, avoid faults such as the recurrent bouncing pilotage of conventional spring presser feet, broken needle, improved quilting quality and operating efficiency.
Description of drawings
With drawings and Examples the utility model is further specified below.
Fig. 1 is an assembling schematic diagram of the present utility model.Among the figure: 1. axle on the quilting machines head, 2. eccentric wheel, 3. eccentric ratio, 4. rear crank is 5. swung transverse axis, 6. preceding crank, 7. lifting linking member, 8. presser feet locating piece, 9. presser bar, 10. presser feet, 11. positioning nuts, 12. positioning screws, 13. the eccentric wheel branch head screw, 14. crank screws, 15. presser bar screwings, 16. connecting rod screw, 17. presser feet screws.
