Abstract
The invention relates to a sewing machine part driving device which comprises a frame, a motor, a presser foot lifting cam, a presser foot lifting ejector rod component, a presser foot lifting pressure rod, a trimming crank, a trimming driving seat, a trimming component and the like. The motor is mounted at the bottom of the frame through the trimming driving seat and a motor fixing seat which are fixed to two ends of a motor shaft. The presser foot lifting cam is mounted on the front side of a motor spindle, the motor drives the presser foot lifting cam to rotate so that the presser foot lifting pressure rod is pressed down, and the presser foot lifting pressure rod presses down the presser foot lifting ejector rod component. The trimming crank is mounted on the rear side of the motor spindle, and the motor drives the trimming driving seat to rotate through the trimming crank. An integral mechanical control structure is simplified, and the trimming component, the presser foot lifting ejector rod component and a main driving system are independent. By the aid of the sewing machine part driving device, trimming efficiency can be improved, vibration and noise are reduced, cost and technological difficulty are reduced by a transmission mechanism and relevance of the mechanism, production efficiency is improved, and post-maintenance is facilitated.
Description
Technical field
The present invention relates to a kind of accessaries of sewing machine drive unit.
Background technology
Original sewing device transmission system mainly adopts upper and lower main shaft Bevel Gear Transmission and two kinds of modes of belt transmission gear-box speed change commutation.The ordinary straight of its total upper and lower main shaft Bevel Gear Transmission is driven computer flat sewing machine and is mainly comprised: frame, upper main shaft, epicone teeth drive pair, perpendicular power transmission shaft, lower cone teeth drive pair, lower main axis.Wherein, upper main shaft, lower main axis, perpendicular power transmission shaft, be installed in frame, in driven by motor, main shaft rotates by epicone teeth drive pair and drives perpendicular power transmission shaft to rotate, and perpendicular power transmission shaft is again by the transmission of lower cone teeth drive pair driving lower main axis.This transmission mechanism is simpler, but upper and lower cone teeth drive pair is high to installation, processing request, and noise is large and noise is difficult controls, and gives oil mass large, increases the fuel-displaced probability of Sewing machines; Directly the driving computer flat sewing machine without oil and mainly comprise of another kind of belt transmission gear-box speed change exchange system: frame, upper main shaft, belt transmission pair, lower main axis, deceleration reverse box.Wherein going up main shaft, lower main axis, deceleration reverse box is installed in frame, in driven by motor, main shaft rotates, by the moving lower main axis of belt transmission subband, rotate, by gear-box speed change exchange system, drive lower main axis turn to rotary speed movement and drive cloth feeding mechanism to move to set.This transmission mechanism has reduced noise by use belt transmission and lubricating oil is used, but integrated model design is complicated, cost is high, and mounting process is not good, and belt rotation system inconvenient maintenance.
Summary of the invention
The object of this invention is to provide a kind of Novel tailoring equipment transmission system, avoid that the machining accuracy that runs in common computer flat seam machine Bevel Gear Transmission is not high, stability is low, noise vibration is large, need the problem of oil supply.
The invention provides a kind of accessaries of sewing machine drive unit, described device comprises that motor (4), frame (7), trimming assembly (1), trimming drive seat (2), trimming crank (3), presser foot lifter cam (5), presser foot lifter depression bar (8), presser foot lifter push rod component (6); Wherein motor (4) is installed on frame (7) bottom by motor shaft (9) two ends fixture axle beds (10), motor fixing seat (11).Stretch out at motor shaft (9) two ends of motor (4), and trimming crank (3) and presser foot lifter cam (5) are installed on respectively in motor (4) two end axles.Motor (4) drives trimming crank (3) to be rotated counterclockwise (from motor afterbody, facing), by trimming, drives seat (2) to drive trimming assembly (1) to carry out trimming action.Motor (4) drives presser foot lifter cam (5) to turn clockwise (from motor afterbody, facing), to pressing down presser foot lifter depression bar (8), then by driving foot lifting mechanism to perform an action to pressing down presser foot lifter push rod component (6).Beneficial effect of the present invention is: a kind of accessaries of sewing machine drive unit provided by the invention, drive source by individual motor as presser foot lifter push rod component and trimming assembly, replaced existing Sewing machines main drive motor to drive by cam mechanism, electromagnet is as the trimming assembly drive pattern of driving switch; Use independent driving motor to replace original presser foot lifter push rod component drive pattern simultaneously.Greatly simplify whole mechanical control structure, realized the independence of trimming, presser foot lifter assembly and main drive system.By accessaries of sewing machine drive unit of the present invention, can improve trimming efficiency, reduce vibration, noise, by transmission mechanism and the coherence of mechanism, reduce costs and technology difficulty simultaneously, enhance productivity, and be beneficial to later maintenance.
