Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Refer to accompanying drawing 1 to 3, the utility model embodiment comprises:
A kind of shut-off mechanism, comprises knife rest, cutting knife 1, motor 2, rotating shaft 3 and capacity eccentric bearing 4; Knife rest comprises base plate 5 and is vertically fixed on the support end 6 on base plate, in order to increase stability, has also welded the reinforcement at right angle between support end 6 with base plate 5.In the present embodiment, support end 6 has two, and two support ends 6 are set up relatively.Support end 6 is provided with vertical guide groove, and guide groove is positioned on two support ends madial wall in opposite directions.And the vertical side of cutting knife 1 is matched with in this guide groove, such cutting knife 1 just can slide up and down along guide groove.Rotating shaft 4 level is fixed on support end 6, and is fixed on the top of support end 6 by sliding bearing or roller bearing; Because rotating shaft 3 is for giving cutting knife 1 transmission, so rotating shaft 3 is above guide groove.Rotating shaft 3 has been set with capacity eccentric bearing 4, the radial direction of capacity eccentric bearing 4 is flexibly connected cutting knife 1, capacity eccentric bearing is hinged on cutting knife 1 by a connecting rod 7.One end connection of rotating shaft 3 is connected to motor 2 by shaft coupling 8, and after motor 2 starts, the rotation of rotating shaft 3 axis makes capacity eccentric bearing 4 stable rotation; Because capacity eccentric bearing 4 outer ring connects cutting knife 1, and cutting knife 1 limits with guide groove; Therefore, when the inner ring eccentric rotary of capacity eccentric bearing 4, the outer ring of capacity eccentric bearing 4 just drives cutting knife 1 to do vertical displacement along guide groove by connecting rod 7.The mode that this structure is compared " cylinder Direct driver cutting knife vertical displacement " is stable many.Because when using multi cylinder to promote cutting knife, the deviation due to transmission speed may cause cylinder moving uneven, and cutting knife can be made like this to be subject to force unbalance.Not only can affect the quality of cut-out, and can to bringing wearing and tearing and unnecessary fatigue damage between mechanism.But the structure of " rotating shaft adds capacity eccentric bearing " that use in this programme can effectively avoid this situation, it is balanced to power that it can make cutting knife be subject to, and improves the whole structure of structure.
Shut-off mechanism also comprises feeler block 9, and feeler block 9 can ensure the off-position of cutting knife 1, cutting knife 1 also can be assisted to complete cut-out simultaneously.Feeler block 9 is fixed on base plate 5; Feeler block 9 is positioned at the below of described cutting knife 1 and is parallel to cutting knife 1, and its length is identical with cutting knife 1.The lateral surface of feeler block 9 and the medial surface of cutting knife 1 are positioned at same perpendicular, because when cutting knife 1 incision, can completely fitting in two above-mentioned sides, cloth could be cut off like this.
In order to improve the quality of cut-out, in shut-off mechanism, also comprise top board 10, lower platen 11, crossbeam 12, first cylinder 13 and the second cylinder 14; The downside that lower platen 11, second cylinder 14 is fixedly arranged on base plate 5 is placed in the upside of base plate 5, and the second cylinder 14 pushes lower platen 11 straight up through base plate 5.Top board 10 is then by crossbeam 12 and the first outstanding top being fixed in lower platen 11 of cylinder 13, and the end of crossbeam 12 is fixed on support end 6.Also be provided with guide pillar 15 between crossbeam 12 and top board 10, crossbeam 12 is provided with through hole, and guide pillar 15 is matched with in through hole, and the lower end of guide pillar 15 is fixed on top board 10.First cylinder 13 connects top board 10 and pushes top board 10 vertical lifting.From said structure, the first cylinder 13 and the second cylinder 14 push top board 10 and lower platen 11 move toward one another respectively, can play the effect of clamping cloth.Can assist like this cutting knife cut off cloth, when avoiding cutting knife because lifting drive cloth and cause position skew, effectively can improve the quality of cut-out.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
