As shown in Figure 1 and Figure 2, because the volume of described rear casing 420 is large, weight is large, in order to make, described rear casing 420 is convenient to open, closure, so that the maintenance of overlock machine and nursing, and make described rear casing 420 hinge point in open and close process durable in use, not fragile, preferably, hinged between the rear wall bottom of the bottom of described rear casing 420 and described base housing 411 realized by following structure: the rear wall bottom of described base housing 411 is provided with hinge seat 421, and the bottom of described rear casing 420 is hinged by bearing pin 422 and described hinge seat 421.Certainly, hinged between the rear wall of described rear casing 420 and described base housing 411 bottom also can be realized by conventional hinge is installed, in a word, as long as make to realize bottom the bottom of described rear casing 420 and the rear wall of described base housing 411 hinged.
For make described tool rest 330 simple in structure, be convenient to manufacture, save material and production cost, and be convenient to install, as shown in Figure 1 to Figure 3, the built-in automatic shearing mechanism of Sewing machines of the present invention also comprises before tool rest fixed mount 332 after fixed mount 331 and tool rest, described tool rest 330 by fixed mount 331 before tool rest and tool rest after fixed mount 332 fixing with described column housing 412.
Embodiment bis-
The built-in automatic shearing mechanism of the Sewing machines of the present embodiment and the version of embodiment mono-are basic identical, the difference of itself and embodiment mono-as shown in Figure 5, being flexibly connected the realization that coordinates with bearing pin 111 by mounting hole 212 between the upper end of described telescopic shaft 110 and described the first lever 210; Wherein said mounting hole 212 is located on described the first lever 210, and described bearing pin 111 is connected with the upper end of described telescopic shaft 110 through described mounting hole 212.Described mounting hole 212 can certainly be located to the upper end of described telescopic shaft 110, described bearing pin 111 is connected with described the first lever 210, can realize equally being flexibly connected between the upper end of described telescopic shaft 110 and described the first lever 210.
The operation principle of the built-in automatic shearing mechanism of Sewing machines of the present invention is: in the time not carrying out trimming action, the telescopic shaft 110 of described drive source 100 is in retracted state, the stationary knife 333 of described moving knife 320 and described tool rest 330 is in separated position, the form of iron core that adopts electromagnet and be located at electromagnet endoporus taking drive source 100 is as example, electromagnet is in power failure state, under the effect of described back-moving spring, described iron core is that telescopic shaft 110 is in retracted mode; In the time that needs carry out trimming action, the electric-control system of overlock machine sends instruction, make electromagnet energising, the resistance that described iron core overcomes back-moving spring under electromagnet magneticaction stretches out fast, drive described the first lever 210 to move up with the pin joint of second connecting rod 240, thereby second connecting rod 240 drives described the second lever 220, make described the second lever 220 drive described cutter shaft 310 to rotate, described cutter shaft 310 drives again described moving knife 320 to rotate, make stationary knife 333 twistings of moving knife 320 and tool rest 330, the suture of Sewing machines is cut off.Back-moving spring iron core stretch out process fast in there is deformation, produce elastic potential energy; After trimming completes, electromagnet dead electricity, described back-moving spring, in the situation that losing external force, discharges elastic potential energy, drives electromagnet core to reset, thereby makes the first lever 210, the second lever 220, second connecting rod 240 realize and resetting, and waits for trimming action next time.
In sum, the built-in automatic shearing mechanism of Sewing machines of the present invention, stable drive, noise are little, and drive source stroke is little, volume is little, financial cost is low, demand to installing space is few, make drive source can be installed on the indent region of Sewing machines main casing rear wall, then make automatic shearing mechanism realize built-in at Sewing machines by the setting of rear casing, make Sewing machines complete machine effect attractive in appearance.In addition, rear casing also plays dustproof effect, makes difficult damage of built-in automatic shearing mechanism of Sewing machines.The present invention not only can be used for overlock machine, also can be used for other Sewing machines such as flat seam machine, flat seaming machine, of many uses.So the present invention has effectively overcome various shortcoming of the prior art and tool high industrial utilization.
Above-described embodiment is illustrative principle of the present invention and effect thereof only, but not for limiting the present invention.Any person skilled in the art scholar all can, under spirit of the present invention and category, modify or change above-described embodiment.Therefore, such as in affiliated technical field, have and conventionally know that the knowledgeable, not departing from all equivalence modifications that complete under disclosed spirit and technological thought or changing, must be contained by claim of the present invention.
