Description
Technical field
The utility model relates to the mechanical type Sewing machines, especially a kind of mop transmission device of Sewing machines.
Background technology
Below the stitch of existing Sewing machines a cloth feeding mechanism is arranged, at the output main shaft eccentric wheel to be arranged, eccentric wheel case has the work feed dental lamina, utilize eccentric wheel to rotate, make the work feed dental lamina prominent prominent lower, tailoring cloth is moved forward, when making two layers of cloth, the upper strata cloth is pushed down by the tooth sole, be difficult for moving forward, and lower layer mix feeding is promoted by the tooth of work feed dental lamina and moves forward the asynchronous movement of two layers of cloth, cause the upper strata cloth holdup time long, the lower layer mix feeding holdup time is short, when therefore making with decorative pattern or twill cloth, and misalignment decorative pattern or twill, needlework are inhomogeneous, give visually plain weak point.
Summary of the invention
The purpose of this utility model provides a kind of upper and lower synchronous cloth-dragging wheel transmission mechanism, and the synchronous rubbing of upper and lower cloth-dragging wheel is the mop transmission device of the Sewing machines of tailoring cloth forward.
The purpose of this utility model institute operation technique scheme, comprise an axle, rocking arm, eccentric rocking bar, basin angle tooth, lower mop wheel shaft, upper mop wheel shaft, left tooth boxboard, two axles, dens in dente boxboard, worm gear, right tooth boxboard, worm screw, be equipped with an axle and two axles between its dens in dente boxboard and the right tooth boxboard, one axle is equipped with basin angle tooth and rocking arm one end axis hole with the key connection, basin angle tooth and worm screw one end angle tooth engagement, worm screw center teeth and the worm gear engagement that is linked and packed with key at two axles, form worm gear, the axle that two axles, one end passes dens in dente boxboard hole is with the key driving tooth that is linked and packed; Be equipped with lower mop wheel shaft and upper mop wheel shaft between left tooth boxboard and the dens in dente boxboard, upper mop wheel shaft is with the key driving cog A that has been linked and packed, and lower mop wheel shaft is with the key driving cog B that has been linked and packed, driving cog A and driving tooth and driving cog B engagement.
Further, pivot pin passes eccentric rocking bar one end axis hole and rocking arm other end axis hole successively.
Further again, an axle and two axles have bearing respectively and between the dens in dente boxboard axis hole; One axle and two axles have bearing respectively and between the right tooth boxboard axis hole.
Also have, lower mop wheel shaft and upper mop wheel shaft have bearing respectively and between the dens in dente boxboard axis hole; Lower mop wheel shaft and upper mop wheel shaft have bearing respectively and between the left tooth boxboard axis hole.
Also have, upper mop wheel shaft axial line parallels with lower mop wheel shaft axial line, and on same vertical plane.
When using the utility model, the eccentric rocking bar other end is connected with eccentric wheel on the main shaft, the output of lower mop wheel shaft and upper mop wheel shaft is respectively fitted with cloth-dragging wheel.Main shaft rotarily drives eccentric rocking bar, eccentric rocking bar drives rocking arm; rocking arm makes axle rotation; thus basin angle tooth is rotated; and basin angle tooth rotates the angle tooth, and cingulum moving worm gear in angle is rotated, and by the driving tooth on two axles driving cog A is rotated again; driving cog A also drives driving cog B and rotates, the cloth-dragging wheel synchronous rotary that mop wheel shaft and lower mop wheel shaft are assembled respectively.
The utility model has the synchronous work feed material of upper and lower cloth-dragging wheel; Be subjected to the main shaft control worm gear can self-locking, effectively control cloth-dragging wheel, can not arbitrarily swing, bouncing pilotage, make the characteristics such as needlework are even.
