Abstract
The invention belongs to the technology of sewing machine, in particular relates to a pressure foot structure of an electronic pattern sewing machine, wherein an air cylinder 1 is installed on an air cylinder connecting plate 5, an air cylinder rod is connected to an air cylinder connector 2, the other end of the air cylinder connector 2 is connected to a rack 3, one end of a pressure foot block 7 is connected to a driving crank 6, the other end of the driving crank 6 is matched with a gear 4, a gear 3 is driven by the air cylinder rod to reciprocate, further to rotate with the gear 4 meshed with the gear 3, the driving crank 6 and the pressure foot block 7 are driven by the rotation of the gear 4 to reciprocate and overturn, the driving crank 6 is of an arch hollow-out shape, the hollow-out most part exceeds a symmetrical centre line of the crank, so that the driving crank 6 can avoid the machine needling to stab the cloth, and a pressure plate 8 is added under the pressure foot block 7, thereby being capable of effectively increasing the range for pressing cloth.
Description
Technical field:
The invention belongs to sewing machine technique, particularly designed a kind of novel presser foot for electronic pattern sewing machine.
Background technology:
Electronic pattern sewing machine constitutes because the pattern of design all is curve by a sealing basically when tailoring cloth, during end that this just need make, and the position when stitching is got back to withdrawal of needle.Simultaneously, when style machine tailoring cloth, particularly when the big cloth of the scope of making, common style machine presser feet does not often have the effect of compress, make original presser feet can only push down a little block space of cloth because make the increase of scope, so also cause easily in that to make the process cloth wrinkling, finally cause making and to proceed.Therefore, making in the process of electro-pattern-sewing machine, presser feet also is to determine to make a key factor whether can completely carrying out.
Summary of the invention:
The objective of the invention is to design a kind of presser foot for the electro-pattern-sewing machine Sewing machines, its driving crank can overturn.
The object of the present invention is achieved like this:
A kind of presser foot of electronic pattern sewing machine, cylinder is installed on the cylinder connecting plate, cylinder rod links to each other with cylinder jointing, the other end of cylinder jointing connects tooth bar, one end of presser feet piece connects driving crank, and the other end of driving crank cooperates with gear, and cylinder rod drives the reciprocating motion of tooth bar, and then the rotation of drive and tooth bar meshed gears, the rotation of gear drives the reciprocal rotary movement of driving crank and presser feet piece.
Control device of the present invention is the control function that realizes like this upset of control driving crank: increase by one at an end of presser feet piece and be attached thereto the driving crank that connects, the other end of driving crank then cooperates with gear, when the rack drives gear movement, driving crank just can be realized flip horizontal.The power of tooth bar is provided by cylinder, cylinder is installed on the cylinder connecting plate, the cylinder rod of cylinder one end links to each other with cylinder jointing, the other end of cylinder jointing connects tooth bar, when cylinder is started working, cylinder rod can drive tooth bar and move back and forth, thereby drives the reciprocal rotary movement of driving crank by the rotation of gear.
Rotary movement of the present invention drives by cylinder, and the engagement that it is characterized in that driving the driving crank upset and be by rack-and-pinion realizes, its reciprocating motion simultaneously then be by cylinder rod stretch back and forth realize.The present invention designs under the presser feet piece has increased a pressing plate, and it can increase the compress scope effectively, and simultaneously for can farthest compress cloth and can not manufacture influence by opposite joint, designed pressing plate can divide plurality of specifications, to adapt to the demand of making of different sizes.
Gear of the present invention is performed such cooperation and restriction, add at the inner ring of gear and to stretch a plane, on the axle of driving crank one end that cooperates with it, also design a plane simultaneously, like this by matched in clearance just can limiting gear radially rotation, process a screwed hole at an end of driving crank simultaneously, after gear is packed into, with moving axially of contiguous block limiting gear, install a spacing shim additional in the outside of contiguous block, with stop screw spacing shim is fastened again.
Driving crank of the present invention adopts the shape of semicircle hollow out, and the largest portion of its hollow out should surpass the symmetrical center line of driving crank, so that can reach the purpose of avoiding the machine eedle-punched non-wovens after the driving crank upset.
The number of parts that the original relatively presser foot of the present invention increases is few, and processing is simple, and cost is low, and can farthest satisfy the demand of making.
Description of drawings:
Fig. 1 is stereogram of the present invention;
Fig. 2 is front view of the present invention;
Fig. 3 is the right view of Fig. 2;
Fig. 4 is the stereogram of driving crank of the present invention.
The specific embodiment:
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, the present invention includes cylinder 1, cylinder jointing 2, tooth bar 3, gear 4, cylinder connecting plate 5, driving crank 6, presser feet piece 7, pressing plate 8, spacing shim 9, stop screw 10, contiguous block 11, cylinder 1 is installed on the cylinder connecting plate 5, cylinder rod links to each other with cylinder jointing 2, the other end of cylinder jointing 2 connects tooth bar 3, one end of presser feet piece 7 connects driving crank 6, the other end of driving crank 6 cooperates with gear 4, cylinder rod drives the reciprocating motion of tooth bar 3, and then the rotation of drive and tooth bar 3 meshed gears 4, the rotation of gear 4 drives the reciprocal rotary movement of driving crank 6 and presser feet piece 7.Its specific implementation is such: one of end increase at presser feet piece 7 is attached thereto the driving crank 6 that connects, and the other end of driving crank 6 then cooperates with gear 4, and when 4 motions of tooth bar 3 driven gears, driving crank 6 just can be realized flip horizontal.The power of tooth bar 3 is provided by cylinder 1, cylinder 1 is installed on the cylinder connecting plate 5, the cylinder rod of cylinder 1 one ends links to each other with cylinder jointing 2, the other end of cylinder jointing 2 connects tooth bar 3, when cylinder 1 is started working, cylinder rod can drive tooth bar 3 and move back and forth, thereby drives the reciprocal rotary movement of driving crank 6 by the rotation of gear 4.Also increased a pressing plate 8 in 7 times designs of presser feet piece simultaneously, it can increase the compress scope effectively.And the restriction of gear 4 is such: at screwed hole of end processing of driving crank 6, after gear 4 packed into, with moving axially of contiguous block 11 limiting gears 4, install a spacing shim 9 additional in the outside of contiguous block 11, with stop screw 10 spacing shim 9 is fastened again.
