Description
Technical field
The invention belongs to the computer plain flat knitter technical field, be specifically related to a kind of device for controlling sinker of knitting mechanism of computer plain flat knitter.
Background technology
The function of sinker is that the coil to forming in knitting mechanism braiding process is pressed to use and helped to move back circle or lopping.Again, in the process that coil is pressed, be to rotate around fulcrum regularly due to sinker, to meet the variation requirement to the coil pressing position, otherwise can't produce and meet the required pressing force of weaving coil, that is, do not have the effect that helps to move back circle or lopping.This be because knitting mechanism in the process of braided fabric, lopping and the barring-on technological requirement that is absolutely necessary, whether stablizing of the quality of lopping and barring-on depends on whether coil is close with coordinating of knitting needle pinhock usually, can coil move back circle fully on knitting needle, and to make the pinhock of coil and knitting needle good fit, coil can move back circle fully on knitting needle, must carry out reasonable tractive and ensure coil is pressed to garment piece.
As described above, due to sinker, around the regular motion of fulcrum, thereby to relate to the device that sinker is controlled be device for controlling sinker.TECHNICAL INFORMATION SOURCES about device for controlling sinker can be seen in disclosed Chinese patent literature, as the CN2905844Y(yarn pressing mechanism of flat knitting machine), the sinker heel guiding block self-driving device of CN100529218C(yarn pressing mechanism of flat knitting machine), the Sinker driving device of a CN201835068U(controlled flat knitting machine) and the Sinker control mechanism of CN100564634C(controlled flat knitting machine), etc.
" device for controlling sinker " typically recommended as Granted publication CN101962866B, this patent of invention for the patent scheme exemplified above, have structure terse and can its specification of objective embodiment the technique effect of record in the 0010th section, but still there is following shortcoming: one, because needs are equipped with independently driving mechanism, it is motor, by the gear driven on the output shaft of driving mechanism and the fixing tooth bar of push rod, thereby by the side-to-side movement of rack drives push rod, driven two triangles of pushing pin that match with push rod middle part (middle part of length direction) (the industry custom claims the sinker guide triangular by the motion of push rod, as follows) and two bolt cam up-down alternative motions, the sinker motion that finally makes to match with push pin triangle and bolt cam (specifically can referring to the 0019th section to 0020 section, the specification of this patent), thereby action link complexity not only, especially driving mechanism (being motor) needs to consume electric energy, thereby both be unfavorable for saving the miniaturization that the energy also is unfavorable for whole control device structure, they are two years old, because a pair of triangle of pushing pin need be equipped with a pair of spring separately, again because two bolt cams need be equipped with a spring separately, thereby the lasting reliability of action is difficult to ensure, because the greatest drawback of spring easily produces fatigue, if replace when frequent inspection and/or the utmost point, be difficult to so even can't to guarantee the accuracy of the operating position of a pair of push pin triangle and two bolt cams, the movement locus of sinker is affected, the effect that final impact is pressed coil, they are three years old, due to drive the motherboard motion be by and the fixing push rod of motherboard on the gear of tooth bar and driving mechanism between the meshing relation realization, therefore the stationarity of motion and the accuracy of position are difficult to lasting assurance because between rack and pinion unavoidably because of the time produce wearing and tearing for a long time.
In view of above-mentioned prior art, still have necessity of improvement, the applicant has done long-term and useful design for this reason, finally formed technical scheme described below, and taking to have carried out simulated test repeatedly in the applicant plant area under rational secrecy provision, it is practicable that result proves.
