Description
Technical field
The utility model belongs to Weaving device device, in particular to a kind of dual-needle-bar mechanism.
Background technique
Existing computer quilter is generally divided into two types, i.e. single head single needle computer quilter and multi-end multi-needle computer is sew with long stitches
The common feature of seam machine, both computer quilters is that the shank pilot hole of a shank is only provided on needle bar frame, this
Though kind of single needle needle bar frame structure is relatively simple, its production efficiency is lower.
Summary of the invention
In view of above-mentioned problem, the purpose of the utility model is to provide a kind of structurally reasonable, manufacture is simple, production effect
A kind of high dual-needle-bar mechanism of rate.
In order to solve the above technical problems, the utility model adopts the following technical scheme:
A kind of dual-needle-bar mechanism, is made of slider-crank mechanism, and the slider-crank mechanism includes being connected to the motor
Upper axis, be connected to described upper axis one end is needle bar crank, and what is connect with the needle bar crank is shank connecting rod, with the shank
What the other end of connecting rod was connected is shank sliding sleeve, is set on the shank sliding sleeve there are two pilot hole, two shanks are each passed through
Its upper and lower side is limited in punch block after being located at the pilot hole of shank sliding sleeve, is pressed from both sides in the lower end of the shank equipped with needle position.
Compared with prior art, the utility model has the following beneficial effects:
A kind of dual-needle-bar mechanism of the utility model development is the improvement to existing quilter single needle needle bar mechanism,
Its main feature is that being provided with two shank pilot holes on needle bar frame, two shanks, two shanks are installed in shank pilot hole
Under the drive of electric-motor drive mechanism, quilting operation can be carried out simultaneously, to effectively improve the production efficiency of quilter.
Detailed description of the invention
Fig. 1 is the utility model schematic view of the front view.
Specific embodiment
Referring to figure 1, a kind of dual-needle-bar mechanism, is made of slider-crank mechanism, the slider-crank mechanism packet
The upper axis 1 being connected to the motor is included, be connected to described 1 one end of upper axis is needle bar crank 2, is with what the needle bar crank 2 was connect
Shank connecting rod 3, what is be connected with the other end of the shank connecting rod 3 is shank sliding sleeve 4, set on the shank sliding sleeve 4 there are two
Pilot hole 5, its upper and lower side is limited in punch block 8 after two shanks 6 are each passed through the pilot hole 5 for being located at shank sliding sleeve 4, described
The lower end of shank 6 is equipped with needle position folder 7.The utility model mechanical motion principle is that two needles 9 are respectively installed in needle position folder 7,
Motor rotation drives the upper axis 1 being attached thereto to rotate, and the rotation of upper axis 1 drives needle bar crank 2 to rotate, and shank connecting rod 3 is connected to
On needle bar crank 2, according to crank principle, shank connecting rod 3 can pump, and the movement of shank connecting rod 3 drives therewith
The up and down motion of connected shank sliding sleeve 4, the shank 6 be across the pilot hole 5 of shank sliding sleeve 4 and fixed thereto, shank 6
Upper and lower side drives the needle position being attached thereto folder 7 and the work of needle 9 to carry out quilting operation under the limit of punch block 8, to effectively mention
The high production efficiency of quilter.
Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic
It is equivalently replaced.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on,
It should be included within the scope of protection of this utility model.
Claims (1)
