Description
Technical field
The utility model relates to full-automatic sewing machine field, particularly relates to the hoisting mechanism of middle depression bar.
Background technology
In prior art, the middle depression bar hoisting mechanism of non-full-automatic sewing machine is hand, but meet with non-rectilinear sewing or
During complex pattern sewing process, in hand lifting, the efficiency of depression bar is then very low.
And automatically the middle pressure hoisting mechanism of template sewing machine is computer control automatic lifting, its structure is: on middle depression bar
Under move reciprocatingly, one end of pressure regulation guide rod is placed in the bar chamber of middle depression bar, and the other end of its pressure regulation guide rod and hoisting mechanism are even
Connect, due to the internal diameter in the restricted diameter of the pressure regulation guide rod bar chamber in middle depression bar, so generally pressure regulation guide rod is relatively thin, cause
Pressure regulation guide rod is very easily broken, is greatly increased machine-spoiled rate, updates the cost that pressure regulation bar increases user frequently, also drops simultaneously
The efficiency of low work.
Utility model content
The purpose of this utility model is to provide a kind of pressure regulation guide rod firmly not easily broken, and the full-automatic mould that operating efficiency is high
Depression bar lifting device in plate use in sewing machine.
Of the present utility model disclose depression bar lifting device in a kind of full-automatic template sewing machine, including middle depression bar, tune
Pressing guide rod, spring and hoisting mechanism, described spring housing is located on pressure regulation guide rod, one end of described pressure regulation guide rod and medium pressure bar
Being connected, the other end of described pressure regulation guide rod is flexibly connected with described hoisting mechanism.The medium pressure bar other end is connected with middle presser feet.
Further, the upper end cap portion of pressure regulation guide rod is placed in pressure regulation guide rod pipe box, and described spring is positioned at described pressure regulation leads
Bar set with medium pressure bar between, owing to spring is limited between pressure regulation leader casing and middle depression bar, when medium pressure bar together with
During the motion of described pressure regulation guide rod, spring is compressed；One end of hoisting mechanism is connected with one end of described pressure regulation guide rod pipe box.Adjusting
Pressure guide rod pipe box bottom and be positioned at pressure regulation guide rod pipe box and be provided with a step, the upper end cap portion of described pressure regulation guide rod and described step
Coordinate, make the upper end cap portion of described pressure regulation guide rod be always positioned in described pressure regulation guide rod pipe box.At the end of sewing, hoisting mechanism
Lift pressure regulation guide rod pipe box by piston rod, then drive pressure regulation guide rod to carry on depression bar in finally driving by pressure regulation guide rod pipe box,
Finally realize carrying on the middle presser feet being connected with middle depression bar.
Wherein, one end of described pressure regulation guide rod and medium pressure bar are connected, and can be described pressure regulation guide rod and medium pressure
Bar is threaded, and as pressure regulation guide rod bottom is provided with external screw thread, and middle depression bar top is provided with internal thread, outside pressure regulation guide rod bottom
The screw-internal thread fit on screw thread and middle depression bar top is fixed.Described pressure regulation guide rod and medium pressure bar are synchronized with the movement.
In such scheme, hoisting mechanism can use electronic mode (as used motor-driven mode) to may be used without pneumatic
Mode (mode of air cylinder driven) is the power promoting.When using pneumatic mode, the piston rod of the cylinder of described hoisting mechanism
One end passes through after cylinder fixes seat threadeds with described pressure regulation guide rod pipe box.
The utility model has the advantage that
1st, it because pressure regulation guide rod of the present utility model and middle depression bar are connected, not that in prior art, pressure regulation guide rod is placed in middle pressure
In the bar chamber of bar, the connected mode that middle depression bar moves reciprocatingly so that the globality of middle depression bar lifting device is higher.
2 secondly because middle depression bar and pressure regulation guide rod mass motion, and both sides are not necessarily to respective self-movement, pressure regulation guide rod straight
Footpath can be equal to bar chamber internal diameter or the external diameter of middle depression bar, so the diameter of pressure regulation guide rod is not by the limiting of bar chamber internal diameter of middle depression bar
System so that the diameter of pressure regulation guide rod of the present utility model can increase more than 30% compared with the diameter of the pressure regulation guide rod of prior art,
The lifting intensity making pressure regulation guide rod is greatly improved, and fastness also significantly strengthens, and ensures that the global reliability of equipment.
3rd, in prior art, average about 10 days of middle depression bar is just disconnected, needs more to renew, and the utility model is substantially not
Fracture, is also not required to often update.
