Abstract
The utility model discloses a double-shaft driving mechanism of an embroidery machine. The double-shaft driving mechanism comprises a transmission main shaft, a driving device, a needle rod and a presser foot rod, wherein the transmission main shaft is transversely arranged on a machine head; the driving device is used for driving the transmission main shaft to rotate; the transmission main shaft drives the needle rod to move up and down through a transmission mechanism I; a presser foot driving shaft is further arranged on the machine head; the presser foot driving shaft is used for driving the presser foot rod to move up and down through a transmission mechanism II; the presser foot driving shaft is connected with the driving device through a transmission mechanism III or is connected with the transmission main shaft through a transmission mechanism IV. According to the double-shaft driving mechanism, the needle rod and the presser foot rod are respectively driven through two rotating shafts, so that the power of a single rotating shaft is reduced, the probability that the rotating shaft is deformed is reduced, and the service life is prolonged, and furthermore because of small transmission interference of two adjacent rotating shaft, the needle rod and the presser foot rod are precisely positioned, and the machining precision is improved.
Description
Technical field
The utility model relates to a kind of embroidery machine, is specifically related to a kind of Two axle drive mechanism of embroidery machine.
Background technology
The presser feet of embroidery machine is to be all pressed on cloth by presser feet Spring driving presser feet by shank, so that when shank rollback, reach the standard grade and form wire loop at the eye of a needle place of eedle, rotating shuttle point hooks after this wire loop rotates a circle and just entangles bottom line, then reach the standard grade and tighten up, embroidery machine just completes a most basic thorn cloth action, produces a needle tracking on cloth.But existing presser feet driving mechanism is owing to sharing a main shaft with shank, drives shank and presser bar to move up and down by a main shaft simultaneously, the power of main shaft is high, moment of torsion is large, therefore to main shaft quality require highly, production cost is large, after long-time use, holds and goes wrong very much.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of embroidery machine Two axle drive mechanism effective, long service life that drives.
The utility model solves the technical scheme that its technical problem adopts:
A kind of Two axle drive mechanism of embroidery machine, comprise that one is laterally arranged on the transmission main shaft on head, drive unit, shank and the presser bar that drives transmission main shaft to rotate, transmission main shaft drives shank to move up and down by transmission mechanism I, on described head, be also provided with presser feet driving shaft, presser feet driving shaft drives presser bar to move up and down by transmission mechanism II, and described presser feet driving shaft is connected in drive unit by transmission mechanism III or is connected with transmission main shaft by transmission mechanism IV.
In the utility model, described transmission mechanism I comprises the cam that is arranged on transmission main shaft, is arranged on the rocking arm on head, and one end of rocking arm drives shank motion.
In the utility model, described transmission mechanism II comprises a presser feet cam, and this presser feet cam is arranged in embroidering machine head and is sleeved on presser feet driving shaft, on described presser feet cam, is connected with adjustable shelf, and the upper and lower part of adjustable shelf is set on presser bar; One is arranged at the presser bar on embroidering machine head, and the bottom of this presser bar is provided with presser feet; One is set in the spring I on presser bar top, and the upper end of spring I withstands on embroidering machine head, and the lower end of spring I withstands on the upper end of adjustable shelf; One is set in presser bar middle part and is positioned at the spring II of adjustable shelf inside, and the upper end of spring II withstands on the top of adjustable shelf inside, and the fixed head that the lower end of spring II and is fixed on presser bar is connected; The inner side of described adjustable shelf bottom and fixed head bottom surface can deciliter be connected.
The beneficial effects of the utility model are: the utility model drives respectively shank and presser bar by two rotating shafts, has reduced the power of single rotating shaft, have reduced the probability of rotating shaft distortion, have extended service life; Further, the transmission of adjacent two rotating shafts is interfered little, can make shank and presser bar accurately locate, and improves machining accuracy.
