Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, to the technical scheme in the utility model embodimentBe clearly and completely described, obviously, described embodiment is only that a part of the present utility model is realExecute example, instead of whole embodiment. Based on the embodiment in the utility model, ordinary skill peopleMember, not making the every other embodiment obtaining under creative work prerequisite, belongs to the utility modelThe scope of protection.
Set forth in the following description a lot of details so that fully understand the utility model, but thisUtility model can also adopt other to be different from alternate manner described here and implement, those skilled in the artCan without prejudice to the utility model intension in the situation that, do similar popularization, below therefore the utility model is not subject toThe restriction of disclosed specific embodiment.
As shown in Figure 1, the utility model discloses a kind of pneumatic clamps line apparatus, comprise and drive cylinder 1, upper slitterSheet 2, bottom knife 3 and billhook 4. Described driving cylinder 1 is provided with two intake interfaces and is respectively cylinder and stretches outAir inlet 8 and cylinder shrink air inlet 9, and described cylinder stretches out air inlet 8 and is provided with the first cylinder adjusting pressuring knob13, described cylinder shrinks air inlet 9 and is provided with the second cylinder adjusting pressuring knob 14. Driving of described driving cylinder 1Lever 5 is connected with one end of billhook connecting rod 6 by connector 10, and billhook 4 is connected to billhook connecting rod 6The other end. Drive on cylinder 1 and be connected with clamp cutter bracing frame 7, support frame as described above be provided with three height fromThe platform structure of left-to-right continuous reduction, cutter 2 is by cutter pressure adjustment knob 11 and middle putting downPlatform structure connects, and bottom knife 3 is connected with the platform structure of the rightmost side by bottom knife pressure adjustment knob 12.The free end of the free end of cutter 2 and bottom knife 3 is relative and keep gap to arrange, and described billhook is positioned at instituteState between gap.
Following introduced operation principle all based on pneumatic control panel to inlet, outlet channel transfer compressed airCarry out on the basis of orderly control of " connect → disconnect → connect → disconnect ", its specific works principle asUnder.
1, pneumatic control panel receives order, connects the motion process of controlling after air valve.
Control after air valve connection, high-speed compressed air is stretched out air inlet at the first cylinder adjusting pressuring knob by cylinderRestriction under, enter and drive in cylinder according to suitable operating air pressure, under the High Pressure of gas,Drive cylinder to promote drive rod and travel forward, under the supporting role of clamp cutter bracing frame, drive rod promotes to connectConnect device, driven again the relatively whole clamp cutter of billhook connecting rod bracing frame to do relative motion (moving forward), thisTime, billhook stretches out forward and extends a segment distance with respect to bottom knife and cutter, and billhook is provided with oneIndividual ancistroid,ancistrous barb, so just can stretch out and be hooked to the end of a thread of having been cut off. So far, complete connectionExtend action after source of the gas.
2, pneumatic control panel receives order, oppositely connects the motion process of controlling after air valve.
Control after the reverse connection of air valve, high-speed compressed air is shunk air inlet in the second cylinder pressure regulation by cylinderUnder the restriction of knob, enter and drive in cylinder, at the High Pressure of gas according to suitable operating air pressureUnder, drive cylinder to promote drive rod and move backward, under the supporting role of clamp cutter bracing frame, drive rod drawsMovement connector, has driven again billhook connecting rod relative to whole clamp cutter bracing frame do relative motion (moving backward),Now, the part that billhook stretches out forward can drag the end of a thread being hooked to, and the end of a thread is brought into by bottom knife andThe jaws region of cutter composition, so just can be by thread end clamp between two blades. So far, completedThe end of a thread that retracts of oppositely connecting after source of the gas moves.
It should be noted that in the whole course of work, cylinder adjusting pressuring knob is can be according to the clamp of equipmentSpeed requirement regulates voluntarily, and pressure is larger, and speed is faster, and the response time of described device will contractShort. Meanwhile, the clamping dynamics of cutter and bottom knife be also can be by cutter pressure adjustment knob andBottom knife pressure adjustment knob suitably regulates, and can adapt to different device requirements, completes clampAction.
Described device drives air cylinder driven billhook to do horizontal movement between upper bottom knife by use, by the end of a threadCut off and move between bottom knife, make sewing machine the end of a thread in the time of withdrawal of needle and narrowing smooth attractive in appearance, can notPlay thread ball phenomenon, ensure the attractive in appearance and stability in process of product.
