Utility model content
Therefore, for above-mentioned problem, the utility model proposes it is a kind of it is simple in structure, easy to adjust, can realize it is automatic Change the linear virtual cut device of control.Which solve the virtual cut devices of the prior art to be easy to cause material deformation, adjusts inconvenience Technical problem.
To achieve the above object, the utility model uses following technical scheme:A kind of linear virtual cut device, including machine Frame, the bottom roller being rotatably arranged in rack, the slitter wheel above bottom roller, the rack are equipped with a cross bar, the cross It can slidingly be equipped with sliding seat on bar, a lead screw for being parallel to cross bar, the rack are rotationally equipped in the rack It is equipped with the servo motor being connected with screw rod transmission, a cavity is equipped in the sliding seat, downslide can be gone up by being equipped in the cavity It is equipped with piston rod dynamicly, the lower end of the piston rod is stretched out outside sliding seat, and the lower end of the piston rod is equipped with a knife rest, described to cut Break bar is rotatably arranged on knife rest, and the upper end of the sliding seat is equipped with one and wears adjusting bolt into cavity, the adjusting spiral shell Spring is connected between the lower end of bolt and the upper end of piston rod, the lower end of the cavity is equipped with the external air feed equipment of a connection Stomata, the air admission hole are equipped with solenoid valve.
Further, the sliding seat is equipped with the range sensor for incuding sliding seat and rack spacing.
Further, the upper and lower ends of the cross bar are equipped with sliding rail, and the upper and lower ends of the sliding seat are equipped with and slide The sliding slot of rail cooperation.
Further, the handwheel for adjusting manually is connected on the lead screw.
By using preceding solution, the utility model has the beneficial effects that:This linear virtual cut device passes through servo electricity Machine, lead screw come realize slitter wheel left and right displacement adjust, realized on slitter wheel by cavity, piston rod, adjusting bolt, spring Under pressing force, i.e., compressing of the spring to piston rod is realized by the elastic of adjusting bolt, so that slitter wheel is to bottom roller Pressure adjust, by cavity, piston rod, stomata, solenoid valve, to realize the rapid uplift of slitter wheel, so as to be convenient to The destruction to material is reduced when slitter wheel left and right adjusting, and the purpose that multi-thread void is cut, structure letter may be implemented in setting in this way It is single, easy to adjust;Further, range sensor is set, can learn that slitter wheel is located at the position of material in real time;Further , by the cooperation of sliding rail, sliding slot, can to horizontally slip more smooth;It further, can be with by the setting of handwheel It realizes and adjusts manually.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model;
Fig. 2 is the sectional view of Fig. 1 left view states.
Specific implementation mode
The utility model is further illustrated in conjunction with the drawings and specific embodiments.
With reference to figure 1, Fig. 2, the present embodiment provides a kind of linear virtual cut device, including rack 1, it is rotatably arranged in rack 1 On bottom roller 2, the slitter wheel 3 above bottom roller 2, the rack 1 is equipped with a cross bar 11, can control cunning on the cross bar 11 It is equipped with sliding seat 4 dynamicly, is rotationally equipped with a lead screw 51 for being parallel to cross bar 11 in the rack 1, the rack 1 is equipped with It is driven the servo motor 52 being connected with lead screw 51, a cavity 41 is equipped in the sliding seat 4, being equipped in the cavity 41 can be upper and lower It is slidably equipped with piston rod 61, the lower end of the piston rod 61 is stretched out outside sliding seat 4, and the lower end of the piston rod 61 is equipped with a knife Frame 62, the slitter wheel 3 are rotatably arranged on knife rest 62, and the upper end of the sliding seat 4 wears the tune into cavity 41 equipped with one Bolt 63 is saved, spring 64 is connected between the lower end and the upper end of piston rod 61 of the adjusting bolt 63, the cavity 41 Lower end is equipped with the stomata 42 of the external air feed equipment of a connection, and the air admission hole 42 is equipped with solenoid valve 7.It is set on the sliding seat 4 It is useful for the range sensor 8 of induction sliding seat 4 and 1 spacing of rack.The upper and lower ends of the cross bar 11 are equipped with sliding rail 12, institute The upper and lower ends for stating sliding seat 4 are equipped with the sliding slot 42 coordinated with sliding rail 12.It is connected on the lead screw 51 for adjusting manually Handwheel 53.
