The utility model relates to a kind of industrial sewing machine with feed dog height governor motion, comprise cloth-feeding teeth of sewing machine main transmission connecting rod, feed dog body, it is characterized in that: described feed dog body is fixed in feed dog height and regulates on support, described feed dog height regulates support two side to be provided with slotted hole, and run through clamping screw, simultaneously female affixed by locking with cloth-feeding teeth of sewing machine main transmission connecting rod.Beneficial effect: the utility model is by regulating the improvement of supporting structure to feed dog, achieve and only need regulate a bolt, the adjustment to Sewing machines feed dog height, horizontal direction can be completed, substantially reduce consumption when assembling or finishing Sewing Machine woker, also reduce the skill requirement to assembler or repairman.
Description
Technical field
The utility model belongs to industrial sewing machine, particularly relates to a kind of industrial sewing machine with feed dog height governor motion.
Background technology
At present in industrial sewing machine assembling and use procedure, often relate to work feed left and right sideslip or the undesirable situation of work feed speed, now just need to regulate feed dog, regulate in current design during feed dog height and often need to divide dismounting just can regulate to pin position Components, very inconvenient, and adjustment easily affects assembly precision.Therefore change feed dog installation adjustment structure to be just extremely necessary.Industrial sewing machine belongs to the precision optical machinery of compact conformation, and the structure of successive dynasties Sewing machines is unanimous on the whole, needs to carry out on the original structure had cured to change very difficult.And owing to needing the positional structure of change compact, in limited space, change original feed dog adjustment structure, making feed dog regulate simple to operation is technical barrier urgently to be resolved hurrily.
Utility model content
The utility model is to overcome deficiency of the prior art, provides a kind of industrial sewing machine with feed dog height governor motion, by the adjustment regulating a bolt can complete height to cloth-feeding teeth of sewing machine and horizontal direction.
The utility model for achieving the above object, be achieved through the following technical solutions, a kind of industrial sewing machine with feed dog height governor motion, comprise cloth-feeding teeth of sewing machine main transmission connecting rod, feed dog body, it is characterized in that: described feed dog body is fixed in feed dog height and regulates on support, described feed dog height regulates support two side to be provided with slotted hole, and runs through clamping screw, simultaneously female affixed by locking with cloth-feeding teeth of sewing machine main transmission connecting rod.
Described feed dog height regulates rack upper surface to be laterally provided with the slot be slidably matched with feed dog body, described feed dog body and slot are slidably matched, described feed dog height regulates below support and is provided with the square groove with the grafting of cloth-feeding teeth of sewing machine main transmission connecting rod, described square groove and slot are arranged in vertical direction, described square groove sidewall is provided with long arc groove, described long arc groove is provided with screwed hole, and is spirally connected with adjusting bolt.
Beneficial effect: the utility model is by the amendment to feed dog structure, achieve and only need regulate a bolt, the adjustment to Sewing machines feed dog height, horizontal direction can be completed, substantially reduce consumption when assembling or finishing Sewing Machine woker, also reduce the skill requirement to assembler or repairman.
