Abstract
The invention provides a feed mechanism of a sewing machine. The feed mechanism comprises a main motor, a cloth feed motor, a feed dog frame and a feed dog fixed to the feed dog frame. The main motor is connected with the feed dog frame through a feed dog lifting mechanism. The cloth feed motor is connected with the feed dog frame through a cloth feed mechanism. The cloth feed mechanism comprises a drive connection rod, a swing connection rod and a feed dog base supported in a bottom plate of the sewing machine in a rotatable mode. One end of the drive connection rod is fixedly connected with an output shaft of the cloth feed motor, and the other end of the drive connection rod is hinged to one end of the swing connection rod. The other end of the swing connection rod is hinged to the feed dog base. The feed dog base is hinged to one end of the feed dog frame. In the feed process, the output shaft of the cloth feed motor swings once in a reciprocating mode within the regulated angle alpha, the feed dog frame and the feed dog can reciprocate twice in a front-back mode together relative to the bottom plate, and therefore the rotation direction switching frequency of the output shaft of the cloth feed motor is greatly decreased, the synchronism between drive of the main motor and drive of the cloth feed motor is ensured, and the sewing quality is improved.
Description
Technical field
The present invention relates to a kind of garment sewing equipment, particularly relate to a kind of sewing machine feeding mechanism and Sewing machines.
Background technology
Sewing machines is of a great variety, and comprise flat seam machine, overlock machine, chain seam machine, flat seaming machine etc., wherein the utilization rate of flat seam machine is the highest.Sewing machines comprises needle bar mechanism, hook line mechanism, thread take-up mechanism, feed mechanism, winding mechanism, feeding pressure mechanism etc., wherein, feed mechanism mainly comprise retainer, be installed in feeding tooth in the middle of retainer on upper end, for drive retainer to do to move back and forth up and down Tai Ya mechanism, for drive retainer do before and after the cloth feeding mechanism that moves back and forth and for driving the motor of Tai Ya mechanism and cloth feeding mechanism.At present, motor, Tai Ya mechanism and cloth feeding mechanism mainly contain two kinds of structures: structure one, use motor to drive Tai Ya mechanism and cloth feeding mechanism, to realize sewing function simultaneously, this structure can realize the sewing of differing needles distance by the adjustment of needle gage mechanism, but can only realize a kind of sewing track; Structure two, use two motors drive Tai Ya mechanism and cloth feeding mechanism respectively, and it freely can control cloth feed amount, therefore, it is possible to easily make various pattern.
At present, the structure of retainer oscillating feed is driven to mainly contain following two kinds by work feed motor:
Structure one, work feed motor are rotated by eccentric cam drivening rod, and realize oscillating feed by swing connecting bar;
Structure two, work feed motor direct-drive four-bar mechanism make feed spool swing, retainer seat is driven to swing together by feed spool, thus realize feeding process, see the sewing machine feeding mechanism disclosed in Chinese utility model patent description that application number is 201220361687.8.
But, there is following defect in said structure one: the cloth pushing table of Sewing machines and cloth conveying teeth every front and back in the horizontal direction round trip, the output shaft of work feed motor just to need in the angular range of regulation reciprocating swing once, therefore, Sewing machines must switch the rotation direction of work feed motor continually, and the load of pretending on work feed motor is just larger; In addition, if user changes the rotating speed of machine spindle at operating pedal, then work feed motor does not catch up with the rotation change of main shaft, and the driving of main shaft synchronously can produce deviation, and then cause sewings degradation with the driving of work feed motor.
Summary of the invention
The shortcoming of prior art in view of the above, the object of the present invention is to provide a kind of sewing machine feeding mechanism that can reduce work feed direction of motor rotation switching frequency.
For achieving the above object, the invention provides a kind of sewing machine feeding mechanism, comprise mair motor, work feed motor, retainer and the feeding tooth be fixed on retainer, described mair motor is connected with retainer by Tai Ya mechanism, described work feed motor is connected with retainer by cloth feeding mechanism, described cloth feeding mechanism comprises drive link, swing connecting bar, and the retainer seat be rotatably supported in baseplate of sewing machine, one end of described drive link is fixedly connected with the output shaft of work feed motor, the other end of drive link and one end of swing connecting bar hinged, the other end and the retainer seat of swing connecting bar are hinged, one end of described retainer seat and retainer is hinged.
Further, described drive link and swing connecting bar, swing connecting bar and retainer seat are all hinged by connecting pin, and the hinged place of drive link and swing connecting bar is provided with one is fixed on clutch shaft bearing in drive link or swing connecting bar, the hinged place of swing connecting bar and retainer seat is provided with one and is fixed on the second bearing in swing connecting bar or retainer seat.
Further, also comprise about two and be oppositely arranged and the fixed part be installed on baseplate of sewing machine lower surface and about one steady pin extended, the two ends, left and right of described steady pin are separately fixed in two fixed parts; The first articulated section that described retainer seat comprises axially extended retainer seat body, the radial extension from retainer seat body one end in left-right direction and the second articulated section extended from retainer seat body other end radial direction, first articulated section and swing connecting bar hinged, second articulated section and retainer hinged, described steady pin is located in retainer seat body and retainer seat body can rotate relative to steady pin.
