In addition, in Sewing machines, be provided with cutting facility and be used for when sewing operation is finished, automatically bottom line being cut off.Therefore, just removed the trouble of manually cutting off bottom line from each sewing section (section).
When in sewing operation, using above-mentioned cutting facility, used Sewing machines for the general irremovable situation of its workbench of type under fix owing to withdraw from the position of bottom line, just without any problem.Yet under the transportable situation of its workbench, its position is not fixed owing to withdraw from bottom line in the next operating process after cutting off bottom line, has just required the bottom line guider using embroidery machine.
In being provided with the conventional bobbin case body 150 of bottom line guider, as shown in Figure 1, there is a disc spring shape guidance coil 155 to be arranged on regularly in the bobbin case body 150, thereby makes bottom line, thereby make the fixed-site that withdraws from bottom line through guidance coil 155 along the direction that suture needle is got off.
In addition, when bottom line was sheared, bottom line must will firmly be supported at the moment.So, the tip that form is a pliers (peak) will be set, and these are most advanced and sophisticated owing to the effect of a lever is descended to come on the both sides of guidance coil 155 on body of Sewing machines (a body).
Yet, owing to the above-mentioned guidance coil 155 that forms with the fine rule circle because the tension force of bottom line is out of shape, withdraw from the position of bottom line or incline against the right side, perhaps incline against the left side.So, just some problems appear, and promptly be difficult to make upper thread on the bottom line hook, but also because broken string and tension imbalance are inconvenient to the sewing operation of embroidering.
In addition, be welded on the bobbin case body 150 owing to be used as a thin end of the guidance coil 155 of independent member, the welding portion between guidance coil 155 and bobbin case body 150 is just very fragile.Also have, guidance coil 155 must be located on the most advanced and sophisticated central part most advanced and sophisticated disturbed to prevent.Yet,,, thereby guidance coil usually is cut off because guidance coil 155 distortion just make guidance coil 155 and most advanced and sophisticated spooling together owing to guidance coil 155 can be out of shape.
Also have, as mentioned above, guidance coil 155 must be positioned on the exact position of bobbin case body.Yet, because member is welded on the bobbin case body separately, will go wrong, that will increase some parts exactly, simultaneously, will pay close attention to just and can finish welding operation, thereby increase cost of manufacture.
Summary of the invention
So, the purpose of this invention is to provide a kind of bobbin thread for sewing machine feeding mechanism, wherein, be arranged on the bottom line guider on the bobbin case body rod bolt, its distortion is prevented from, thereby just can make fixed-site and the maintenance stably of withdrawing from bottom line, thereby improvement sewing quality and ability to work, simultaneously, reduce the quantity of parts and manufacturing process, thereby just reduced cost of manufacture.
According to the present invention, the bobbin thread for sewing machine feeding mechanism comprises the bobbin case body 50 that has rod bolt 51, it is characterized in that: the rod bolt 51 of bobbin case body 50 forms as a whole with the bottom line guider 15a at this body one side place.
