Specific embodiment
As shown in Figure 1 to Figure 3, for disclosed a kind of noose and the keyhole function all-in-one of switching fast realized of the utility model, comprise board 10 and be installed on the support 20 on board 10, on board 10, be provided with needle plate 30, the upside of described support 20 is provided with noose mechanism, one side on described support 20 and that be positioned at cover junction structure is provided with by automatically the cutting keyhole device and be located at the apparatus for fast switching on board 10 of controller control, and apparatus for fast switching is positioned at the downside of automatically cutting keyhole device.Because of the basic function that noose mechanism possesses for legacy equipment, will not do unnecessary statement in the present embodiment.
In above-mentioned, the described keyhole device of automatically cutting comprises automatic cutter mechanism and hand-powered cutter mechanism, and hand-powered cutter mechanism is positioned at a side of automatic cutter mechanism.
The concrete structure of described automatic cutter mechanism is: the upside of support 20 is provided with cylinder mounting plate 40, on cylinder mounting plate 40, be installed with cylinder 41, the push rod of cylinder 41 is fixedly connected with the cutter bar 50 of being located at cylinder mounting plate 40 belows through cylinder mounting plate 40, the downside of cutter bar 50 is installed with cutter holder head 60, and blade 61 is installed on cutter holder head 60.Described cutter bar 50 side fixed covers are provided with cutter bar chuck 51 sides and are arranged with cutter bar and trap 52, the cutter bar on cutter bar 50 trap 52 and cutter bar chuck 51 between be provided with stage clip 53.Automatic cutter mechanism, in the process of work, controls its work by controller.Also can be the expansion neck of cutter bar 50 for cutter bar chuck 51, can be to be also fixed on cutter bar 50 and to run through cutter bar 50 pins, or projection or the bulge loop of welding and cutter bar 50.
The concrete structure of described hand-powered cutter mechanism is: a side of support 20 is provided with switch installation board 70, and the hand switch 71 being electrically connected with controller is installed on switch installation board 70.For hand-powered cutter mechanism, it is only the single-step operation in order to demonstrate or in use to carry out.
