Position belongs to the prior art to the adjusting of needle gage, and this will not be repeated here.
In order to realize close joint function, the utility model includes a kind of close joint driving mechanism of sewing machine, as shown in Figs 1-4,
Including the close joint electromagnet 3 being fixed on the bottom plate 13 and the close joint electromagnet being arranged on the close joint electromagnet 3
Iron core 4, the close joint electromagnet 3 was powered and drove the close joint electromagnet iron core 4 with the second movement travel campaign when trimming, described
Second movement travel is less than first movement travel, which can be set to the dynamic of close joint electromagnet iron core 4
The first buffer part 11 arrives the distance of the end close to first buffer part 11 of close joint electromagnet 3 on power output end, described close
The power output end for stitching electromagnet iron core 4 is the one end being connected with the power intake for backstitching electromagnet iron core 2, described to backstitch electricity
The power intake of magnet iron core 2 be one end opposite with the power output end for backstitching electromagnet iron core 2, stretch out described in
Electromagnet 1 is backstitched, the power output end of the close joint electromagnet iron core 4 by connection structure and backstitches the dynamic of electromagnet iron core 2
The connection of power input terminal, the close joint electromagnet iron core 4 backstitch the fortune of electromagnet iron core 2 by power output end output power drive
Dynamic, the power intake for backstitching electromagnet iron core 2, which receives the power of the close joint electromagnet iron core 4 and is transmitted to, backstitches electromagnet
The power output end of iron core 2 pulls swing seat 7 to move to the position under minimum needle gage state in turn to drive executing agency to move,
Sewing machine carries out trimming after close joint work under the state.The power output end of the close joint electromagnet iron core 4 and it is described fall
Stitch the connection structure between the power intake of electromagnet iron core 2 are as follows: the power for backstitching electromagnet iron core 2 is defeated
Enter end and be fixedly connected with connecting column 5, is provided with strip-shaped hole 6, the company on the power output end of the close joint electromagnet iron core 4
It connects column 5 to be inserted into the strip-shaped hole 6 and can move along the length direction of the strip-shaped hole 6, the sewing machine is in off position
Under, the connecting column 5 is resisted against the strip-shaped hole 6 close to described one end for backstitching electromagnet iron core 2；The length of the strip-shaped hole 6
Degree is greater than the movement travel for backstitching electromagnet iron core 2 and ruler of the connecting column 5 on the length direction of the strip-shaped hole
It is the sum of very little.
The utility model by close joint electromagnet iron core 4 and backstitching above-mentioned connection structure being arranged between electromagnet iron core 2,
And the movement travel that close joint electromagnet iron core 4 is arranged is less than the movement travel for backstitching electromagnet iron core 2, makes sewing machine in trimming
When, electromagnet iron core 2 is backstitched with lesser stroke motion by the drive of close joint electromagnet iron core 4, so that swing seat 7 be pulled to move to
Minimum needle gage or required needle gage, and then close joint function is completed, the driving mechanism of above-mentioned sewing machine does not need complicated sealing and executes
Mechanism simplifies the structure of close joint mechanism.In addition, by being fixedly connected with setting in the power intake for backstitching electromagnet iron core 2
Connecting column 5 opens up strip-shaped hole 6 on the power output end of close joint electromagnet iron core 4, and is inserted into connecting column 5 in strip-shaped hole 6 simultaneously
It can be moved along the length direction of strip-shaped hole 6, and sewing machine is in a quiescent state, connecting column 5 is resisted against strip-shaped hole 6 close to
Stitch one end of electromagnet iron core 2；The length of strip-shaped hole 6 is greater than the movement travel for backstitching electromagnet iron core 2 simultaneously and connecting column 5 exists
The sum of size on the length direction of strip-shaped hole 6, when sewing machine may be implemented backstitching, 3 no power of close joint electromagnet backstitches electromagnetism
Body 1 is powered, and connecting column 5 will not produce between electromagnet iron core 2 and close joint electromagnet iron core 4 in movement in strip-shaped hole 6 to backstitch
Raw interference when sewing machine trimming, backstitches 1 no power of electromagnet, close joint electromagnet 3 is powered, and close joint electromagnet iron core 4 passes through bar shaped
The be connected one end of column 5 of hole 6 drives and backstitches electromagnet iron core 2 and realize close joint with smaller stroke motion, and above-mentioned driving mechanism is logical
The ingehious design for crossing above-mentioned connection structure can guarantee that sewing machine can be achieved at the same time and backstitch function and close joint function, and freely suitable
Freely convert therebetween.
The utility model is not limited to above-mentioned specific embodiment, and various modifications and changes may be made to the present invention.
All foundation the technical essence of the utility model, should all to embodiment of above any modification, equivalent replacement, improvement and so on
Included in the protection scope of the utility model.
