Description
Technical field
The utility model belongs to the Backsewing unit technical field on Sewing machines, and the automatic hook line especially related on a kind of chain type sewing machine backstitches assembly.
Background technology
At present, chain type sewing machine all can carry out the effect backstitching to reach reinforcing after making one section of linear slit.The structure that backstitches on existing chain type sewing machine is mostly Non-follow control, it in use needs to stop and manually backstitches reinforcing after having made one section of linear slit, this just seems when some need to make continuously and the cloth of operation uses comparatively inconvenience easily affects the operating efficiency of making; Be exactly existingly backstitch mechanism in use in addition, its backstitch after sewing line easily loosen, consolidation effect is unsatisfactory; Therefore be necessary to be improved.
Summary of the invention
The purpose of this utility model is the deficiency existed for above-mentioned prior art, provides the automatic hook line on a kind of chain type sewing machine to backstitch assembly, it have structure simple, sewing efficiency can be improved and backstitch post-reinforcing effect preferably feature.
To achieve these goals, the technical scheme that the utility model adopts is: the automatic hook line on a kind of chain type sewing machine backstitches assembly, comprises motor and gear-driven assembly, and described gear-driven assembly is connected on the power output shaft of motor; It also comprises eccentric wheel assembly, hooked needle shaft, crochet hook, curved needle shaft, looper, protects pin eccentric shaft and protect pin; Described eccentric wheel assembly is arranged on the power output shaft of gear-driven assembly, and described curved needle shaft is linked by the power output shaft gears meshing of the gear on it and gear-driven assembly; Described crochet hook is connected on hooked needle shaft, and described hooked needle shaft and eccentric wheel assembly link; Described looper is connected with curved needle shaft, described in protect pin eccentric shaft and linked by eccentric wheel and curved needle shaft, described in protect pin and protect pin eccentric shaft and be connected; Described crochet hook, looper and protect pin collaboration.
Described eccentric wheel assembly comprises eccentric wheel, abutment sleeve, rocker arm bracket and rocking arm, and described rocking arm is movably arranged in rocker arm bracket, and described rocker arm bracket and abutment sleeve are articulated and connected, and described eccentric wheel is arranged in abutment sleeve and it coordinates with hooked needle shaft sleeve.
After adopting said structure, the utility model is compared to the prior art advantageously: structure of the present utility model is simple, hooked needle shaft, curved needle shaft and protect pin eccentric shaft and all automatically controlled by motor, compared its use of existing Non-follow control convenient, effectively can improve sewing efficiency; The utility model is by crochet hook, looper and the cooperation protecting pin, and it in use can form one forever can not the wire loop of sideslip, can realize preferably backstitching reinforcing.

Detailed description of the invention
The following stated is only preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model, further illustrates below in conjunction with drawings and Examples to the utility model.
Embodiment, is shown in shown in Fig. 1 to Fig. 5: the automatic hook line on a kind of chain type sewing machine backstitches assembly, comprises motor 10, gear-driven assembly 20, eccentric wheel assembly 30, hooked needle shaft 40, crochet hook 41, curved needle shaft 50, looper 51, protects pin eccentric shaft 60 and protect pin 61; Gear-driven assembly 20 is connected on the power output shaft of motor 10, and when motor 10 operates, gear-driven assembly 20 can provide kinetic energy to export like this.Eccentric wheel assembly 30 is arranged on the power output shaft of gear-driven assembly 20, described eccentric wheel assembly 30 comprises eccentric wheel 31, abutment sleeve 32, rocker arm bracket 33 and rocking arm 34; rocking arm 34 is movably arranged in rocker arm bracket 33; rocker arm bracket 33 and abutment sleeve 32 are articulated and connected, and eccentric wheel 31 is arranged in abutment sleeve 32 and it coordinates with hooked needle shaft 40 sleeve; Be provided with axle sleeve at the other end of hooked needle shaft 40, axle sleeve is fixedly connected with support, crochet hook 41 is fixedly installed on support; Like this, movable eccentric wheel 31 can be with to work when gear-driven assembly 20 outputting power, and then power transmission to hooked needle shaft 40, thus allow crochet hook 41 carry out the operation of hook line.Be mounted with gear in the end of curved needle shaft 50, this gear can link with the power output shaft gears meshing on gear-driven assembly 20, to guarantee to obtain power supply; Be provided with axle sleeve in the end of curved needle shaft 50, axle sleeve is fixedly connected with support, looper 51 is fixedly installed on support; Protect pin eccentric shaft 60 to be linked by eccentric wheel 31 and curved needle shaft 50, be provided with axle sleeve equally protecting on pin eccentric shaft 60, axle sleeve be fixedly connected with support, protect pin 61 and be fixedly installed on support; Like this after driving gear component 20 outputting power is to curved needle shaft 50, it not only can drive looper 51 operation, and can also drive and protect pin eccentric shaft 60 and work, thus allows and protect pin 61 and carry out operation simultaneously.Above-mentioned crochet hook 41, looper 51 and protect the trough that pin 61 is all positioned at Sewing machines underpart, and cooperatively interact between it, namely in use, hook line 41 can hook needlework, needlework on itself and looper 51 can form a wire loop, and protect pin 61 and can wire loop be positioned, prevent wire loop sideslip in making, to realize backstitching reinforcing preferably.
