Rolling-up mechanism include the lining cloth after sewing up for rolling closed reel, for the motor driving closed reel to rotate, sew up for compacting after lining cloth system for compacting and for the lining cloth after stitching is played the buffer gear of cushioning effect, closed reel is arranged on the power transmission shaft of motor, buffer gear is arranged in the sewing machine frame away from cradle side, and system for compacting is arranged in the frame between buffer gear and closed reel。
System for compacting includes fixed mount, fixed mount has been rotatably coupled the first pressure roller, fixed mount is provided with for coordinating the second pressure roller rotated with the first pressure roller, the gap being available for the lining cloth traverse after sewing up it is provided with between second pressure roller and the first pressure roller, second pressure roller two ends have been rotatably coupled contiguous block, being rotatably coupled bolt on contiguous block, bolt is located in fixed mount and threadeds with fixed mount。
Buffer gear includes first connecting rod, second connecting rod and bumper bracket, first connecting rod is rotatably connected in frame by bearing block, one end of second connecting rod and one end of first connecting rod are fixed, the other end of second connecting rod and one end of bumper bracket are fixed, and are provided with the through hole being available for the lining cloth traverse after sewing up in bumper bracket。
Hemmer is provided with the guide bracket for preventing the lining cloth before sewing up from deviating from from hemmer away from one end of sewing machine。
Sewing machine is provided with the leading truck for the lining cloth after sewing up plays guide effect away from the side of hemmer, is provided with the opening being available for the lining cloth traverse after sewing up in leading truck。
The method have the benefit that the present invention achieves the stitching to lining cloth by the mode of mechanization and processes, compared with the mode that conventionally employed manual operation sewing machine sews lining cloth, improve stitching efficiency and the suture quality of lining cloth, also reduce the labor intensity of staff simultaneously, save the cost of labor of enterprise。

Detailed description of the invention
The sewing machine of automotive seat leather sheath production lining cloth as shown in figs 1 to 6, including frame 1, the rolling-up mechanism of the lining cloth after being provided with the cradle 2 for the lining cloth before sending stitching in frame 1 and sewing up for rolling, frame 1 between cradle 2 and rolling-up mechanism is provided with sewing machine 3, sewing machine 3 towards cradle 2 side, the stitching for cradle 2 is sent is installed before lining cloth carry out the hemmer 31 of doubling。
Rolling-up mechanism include the lining cloth after sewing up for rolling closed reel 51, for the motor 52 driving closed reel 51 to rotate, sew up for compacting after lining cloth system for compacting and for the lining cloth after stitching is played the buffer gear of cushioning effect, closed reel 51 is arranged on the power transmission shaft of motor 52, buffer gear is arranged in the sewing machine 3 frame 1 away from cradle 2 side, and system for compacting is arranged in the frame 1 between buffer gear and closed reel 51。
System for compacting includes fixed mount 61, fixed mount 61 has been rotatably coupled the first pressure roller 62, fixed mount 61 is provided with for coordinating the second pressure roller 63 rotated with the first pressure roller 62, the gap being available for the lining cloth traverse after sewing up it is provided with between second pressure roller 63 and the first pressure roller 62, second pressure roller 63 two ends have been rotatably coupled contiguous block 64, being rotatably coupled bolt 65 on contiguous block 64, bolt 65 is located in fixed mount 61 and threadeds with fixed mount。
Buffer gear includes first connecting rod 71, second connecting rod 72 and bumper bracket 73, first connecting rod 71 is rotatably connected in frame 1 by bearing block 711, one end of one end of second connecting rod 72 and first connecting rod 71 is fixed, one end of the other end of second connecting rod 72 and bumper bracket 73 is fixed, and is provided with the through hole 731 being available for the lining cloth traverse after sewing up in bumper bracket 73;When closed reel is when rolling lining cloth, the diameter of the lining cloth volume in closed reel can be increasing, namely the rolling speed that can make lining cloth is more and more faster, so, the stitching speed of lining cloth can not caught up with the rolling speed of closed reel by sewing machine, and by the setting of buffer gear, bumper bracket in buffer gear can around gantry rotation under the effect of first connecting rod and second connecting rod, thus when the diameter of the lining cloth volume in closed reel increases, bumper bracket can be rotated up at leisure, thus making up the length of lining cloth required after closed reel is accelerated because of rolling speed。
Hemmer 31 is provided with the guide bracket 311 for preventing the lining cloth before sewing up from deviating from from hemmer 31 away from one end of sewing machine 3;Setting by guide bracket 311, it is possible to prevent the lining cloth before sewing up from deviating from from hemmer 31。
Sewing machine 3 is provided with the leading truck 32 for the lining cloth after sewing up plays guide effect away from the side of hemmer 31, is provided with the opening being available for the lining cloth traverse after sewing up in leading truck 32;Setting by leading truck 32, it is possible to make the lining cloth being positioned on sewing machine keep smooth。
The work process of the present invention is: be placed on cradle by lining cloth volume to be stapled, in the guide bracket of lining cloth volume, the mode of serpentine-like shape enters in hemmer after being wound around, lining cloth volume by sewing machine, its peristome is sewed up after hemmer doubling, the lining cloth after stitching sequentially pass through the opening in leading truck, the through hole in bumper bracket and the gap between the second pressure roller and the first pressure roller after rolling in closed reel。
Embodiment described above is only that the preferred embodiment of the present invention is described, and not the spirit and scope of the present invention is defined。Under the premise without departing from design concept of the present invention; various modification that technical scheme is made by this area ordinary person and improvement; protection scope of the present invention all should be dropped into, the technology contents that the present invention is claimed, all record in detail in the claims。
