As mentioned above, transmission mechanism for needle bar and tape wheel frame transmission mechanism are as extraordinary embroidering machine head two big core components, the transmission mechanism complex structure that its power transmission shaft, the axis of guide and travelling gear etc. are formed, add bundle string pendulum mouth transmission mechanism and line ball transmission mechanism, filled up by transmission device in the whole head shell, bring many inconvenience for assembling head and regular maintenance from now on, also increased the operation energy consumption of head simultaneously.
Summary of the invention
It is comparatively simple that the utility model purpose provides a kind of structure, the extraordinary embroidering machine head transmission device of being convenient to assemble.
For achieving the above object, the technical solution adopted in the utility model is: a kind of extraordinary embroidery machine head drive device, comprise the transmission mechanism for needle bar that is installed in the head shell, tape wheel frame transmission mechanism, bundle string pendulum mouth transmission mechanism and the synchronous line ball transmission mechanism that drives by the shank driving main shaft, each transmission mechanism drives via the driving main shaft of Electric Machine Control, described transmission mechanism for needle bar comprises crank cam, the shank drive block, be fixed in the protruding handle of driving on the shank, described tape wheel frame transmission mechanism comprises that an end is equipped with and is sheathed on the spiral driven gear of the helical gear engagement on the tape wheel drive main shaft, the other end has the supporting d-axis of an output spur gear, and be sheathed on the driven wheel that has rotating cylinder on the shank, driven wheel and the engagement of described output spur gear; Described shank drive block sliding sleeve is in the bottom of described supporting d-axis.
In the technique scheme, described bundle string pendulum mouth transmission mechanism, parts such as synchronous line ball transmission mechanism all can adopt prior art, described supporting d-axis is the power transmission shaft of tape wheel carrier, it is again the axis of guide of shank drive block, its input connects with a pair of helical gear that is connected by tape wheel main shaft, the rotation of main shaft is driven power transmission shaft (supporting d-axis) rotation through the transmission of gear, the output of power transmission shaft is exported through the pair of straight gear, this is the driven wheel that has rotating cylinder to the output gear in the spur gear, described rotating cylinder and spur gear are structure as a whole, and are used for hookup wire wheel carrier and band and lead mouth (the line wheel carrier is similar with mounting structure and prior art that band is led mouth); Crank cam in the described transmission mechanism for needle bar is connected with the shank driving main shaft, the output of crank cam is butted on the shank drive block, make drive block edge supporting d-axis bottom reciprocating motion with the eccentric rotary of crank cam, again by being fixed in the protruding handle of driving on the shank and the clamping of drive block, driving shank finishes, following pin, therebetween, because when supporting d-axis as tape wheel carrier power transmission shaft is to rotate with the spiral driven gear, the slip up and down reciprocatingly on d-axis of this and shank drive block is contradiction not, thereby, the supporting d-axis become the axis of guide of shank drive block and line wheel carrier power transmission shaft both unite two into one, so just, head drive device be can simplify, the assembling of head and maintenance in the future are beneficial to.
In the technique scheme, be provided with clutch between described shank driving main shaft and the needle bar crank cam drive mechanism, include the sliding clutch cam that inserts in needle bar crank cam spindle nose, described clutch cam is made up of the groove that is subjected on left, center, right three part cams and the right side, left part radially the eccentric slideway of presser feet when clutch state operate as normal, driving presser feet contacts with the presser feet roller, the middle part radially eccentric cam of macromutation is the pressure foot lifting slideway, when the clutch disengaged position, promote presser feet, the axial reducing face in right side is provided with two cylindrical cams, nearly inboard cylindrical cam radially is slick and sly helical curve, the cylindrical cam of outer radial is curved, constitute described clutch slideway, the protruding boss of the driving that the clutch of right side is connect by groove and main shaft rigidity cooperates.
Above, because the setting of the eccentric slideway of pressure foot lifting slideway and presser feet on the clutch cam right side, the input of foot device (presser feet roller) is when the head duty, be positioned at the eccentric slideway slippage of presser feet, drive the transmission of driving lever through presser feet, presser feet is pumped, and break away under the off position at head, along with moving, clutch cam breaks away from the crank cam main shaft outward, the presser feet roller enters the pressure foot lifting slideway, makes pressure foot lifting to peak when the head stall, and being provided with of two slideways replaced the drives structure of motor-driven presser feet in the past, save the head space that motor occupies, also simplified the presser feet transmission mechanism simultaneously.
Because the technique scheme utilization, the advantage that the utility model compared with prior art has is:
1, the utility model with the shank drive block sliding sleeve in the transmission mechanism for needle bar in supporting d-axis bottom as the tape wheel shaft, because the transmission of tape wheel and the slippage of drive block do not conflict, therefore saved the drive block axis of guide in the transmission mechanism for needle bar in the past, the drive block axis of guide and tape wheel shaft unite two into one, under the situation that does not influence the normal transmission of two mechanisms, simplify overall drive, be beneficial to the assembling of head and maintenance in the future;
2, utilize the drive source of the eccentric slideway of pressure foot lifting slideway on the clutch cam right side and presser feet as foot device, saved the drives structure of motor in the past, simplify the presser feet transmission mechanism on the one hand, saved space in the machine on the other hand, be convenient to the assembling of transmission device.
