Detailed description of the invention

By particular specific embodiment, embodiment of the present utility model being described below, those skilled in the art can be by this Content disclosed by description understands other advantages of the present utility model and effect easily.

It should be clear that structure depicted in this specification institute accompanying drawings, ratio, size etc., the most only in order to coordinate description to be taken off The content shown, understands for those skilled in the art and reads, being not limited to this utility model enforceable restriction bar Part, therefore do not have technical essential meaning, the modification of any structure, the change of proportionate relationship or the adjustment of size, do not affecting Under effect that this utility model can be generated by and the purpose that can reach, all should still fall in the technology disclosed in this utility model In the range of Rong get Neng is contained.Meanwhile, in this specification cited as " on ", D score, "left", "right", " middle " and " one " Deng term, be merely convenient to narration understand, and be not used to limit the enforceable scope of this utility model, its relativeness It is altered or modified, is changing under technology contents without essence, when being also considered as the enforceable category of this utility model.

The application relates to a kind of Scissoring device, this Scissoring device and the equipment such as layout machine, labeler and constitutes automatic cutting System, and layout machine, labeler and Scissoring device arrange successively along direction before and after Cloth Cutting production line.In the application certainly The Scissoring device of dynamic cutting system includes frame, extend up and down cut-off knife 1, X to motion bracket, Y-direction motion bracket and transport up and down Motivation structure, described X is arranged in frame to motion bracket and can move along the longitudinal direction, and described Y-direction motion bracket is arranged on X On motion bracket and can move in left-right direction, described up-down mechanism is arranged on Y-direction motion bracket；Such as Fig. 1 and Tu Shown in 2, described up-down mechanism is provided with the rotatable and solid knife bar 2 that can move back and forth up and down, the upper end of described cut-off knife 1 It is connected by screw is fixing with the lower end of solid knife bar 2.

In above-mentioned Scissoring device, when X moves along X forwards, backwards to motion bracket, Y-direction motion bracket can be driven, transport up and down Motivation structure and cut-off knife 1 synchronously move forwards, backwards along X；When Y-direction motion bracket moves left and right along Y-direction, up and down motion can be driven Mechanism and cut-off knife 1 synchronously move left and right along Y-direction；When the solid knife bar 2 in up-down mechanism moves back and forth up and down and rotates, Cut-off knife 1 can be driven synchronously to move back and forth up and down and rotate, and then difformity can be cut out on fabric.Therefore, above-mentioned sanction Cut the cut-off knife 1 in device achieve along while Z-direction up and down reciprocatingly high-speed motion can rotary motion, and coordinate along X to before Rear movement and moving left and right along Y-direction, thus reach surface trimming, different fabrics are carried out the purpose of difformity cutting, and Its cutting precision is high, cutting speed is fast, cutting efficiency is high, labor intensity is low, use the time long, and the final fabric that reduces is cut into Originally, fabric cutting quality is improved.

In the present embodiment, described X is driven to motor by X to motion bracket, and X to motor by X to drive assembly and X to Motion bracket is connected；Described X to drive assembly can use following structure: X to drive assembly to include front and back extending and with X to The output shaft of motor fixes the X of connection to screw mandrel and the X that coordinates to wire rod thread with X to nut, and described X fixes to nut At X in motion bracket；Therefore, when X is to electric machine rotation, X synchronously rotates to screw mandrel to driven by motor X, therefore X is to nut band Move X to motion bracket along X moving axially back and forth to screw mandrel.Described Y-direction motion bracket is driven by Y-direction motor, and Y-direction motor leads to Crossing Y-direction drives assembly to be connected with Y-direction motion bracket；Described Y-direction drives assembly can use following structure: Y-direction drives assembly Extend including left and right and fix the Y-direction screw mandrel being connected and the Y-direction spiral shell coordinated with Y-direction wire rod thread with the output shaft of Y-direction motor Mother, described Y-direction nut is fixed in Y-direction motion bracket；Therefore, when Y-direction electric machine rotation, Y-direction driven by motor Y-direction screw mandrel synchronizes Ground rotates, therefore Y-direction nut drives Y-direction motion bracket axially moving left and right along Y-direction screw mandrel.

Further, as shown in Figures 2 and 3, described up-down mechanism also includes the peace being fixed on Y-direction motion bracket Filling plate 3, the Z-direction motor 4 being arranged on described installing plate 3 and rotatably drive axle 5, described Z-direction motor 4 is by first Gear unit is connected with drive shaft 5 and drives drive shaft 5 to rotate, and described drive shaft 5 is by the second gear unit and solid knife bar 2 are connected and drive solid knife bar 2 to move back and forth up and down.Power is passed sequentially through the first gear unit, driving by described Z-direction motor 4 Axle 5 and the second gear unit pass to solid knife bar 2, thus drive solid knife bar 2 and cut-off knife 1 synchronously to move back and forth up and down, and then Automatic cutting fabric；Above-mentioned up-down mechanism is on the premise of ensureing fabric cutting precision, and its structure relatively optimizes, simplifies, Consequently facilitating its installation, maintenance and maintenance, and failure rate is low, running noise are low, contribute to improving the working environment of operator, It is easy to client use.

Preferably, as shown in Figures 2 and 3, described first gear unit includes being fixed on the output shaft of Z-direction motor 4 First sheave 61, the second sheave 62 being fixed in drive shaft 5 and drive V-belt 63, described first sheave 61 and the second sheave 62 are connected by drive V-belt 63, and the outer peripheral face of described first sheave 61 and the second sheave 62 is equipped with for accommodating transmission V With the V-shaped groove of 63, and V-shaped groove is suitable with drive V-belt 63.The output shaft of Z-direction motor 4 drives the first sheave 61 to rotate, then and One sheave 61 drives the second sheave 62 to rotate by V-shaped groove, thus drives drive shaft 5 to rotate.First sheave 61 and drive V-belt 63, between drive V-belt 63 and the second sheave 62, the transmission of power is all the two sides of the two sides by drive V-belt 63 and V-shaped groove Compress generation frictional force and carry out power transmission, therefore, when overload phenomenon occurs, between the first sheave 61 and drive V-belt 63 There will be skidding, frictional force between the two is not enough to drive drive V-belt 63 to move, thus realizes automatically stopping during overload Machine, is prevented effectively from overload, it is ensured that job safety, and safeguards simple and convenient.It addition, described first sheave 61 and Z-direction motor 4 is defeated Shaft, the second sheave 62 are all connected by expansion sleeve 7 is fixing with drive shaft 5, and expansion sleeve 7, also known as expansion set, is a kind of standard component, main Be used for wheel and the connection of axle, by tighten high-strength bolt on expansion sleeve 7 make to produce between wheel and the female surface of axle pressure and Frictional force, thus realize load transmission.
