The form or upper section of profile shaft section and the radial section of lower section is square or rectangle, which is used for and slitter shaft
Upper and lower limited block cooperation.The lower end of slitter shaft 5 penetrates the centre bore of driven gear 18, and can be along the centre bore of driven gear 18
Lower linear movement.Slitter shaft lower position block 28 is mounted on the upper surface of driven gear 18, and one side is plane, with slitter shaft 5
The axial plane of lower section contacts, rotation of the limitation slitter shaft 5 relative to driven gear 18.Cutter motor mounting rack 7 is fixed on gear
The top of mounting plate 3, slitter shaft Lower shaft sleeve 19 are mounted on the bottom plate 4 of cutter motor mounting rack 7.Turntable 9 is rotatably mounted
On the top of cutter motor mounting rack 7, slitter shaft Upper shaft sleeve 8 is mounted on turntable 9.Slitter shaft upper limit position block 10 is mounted on cutter
On axis Upper shaft sleeve 8, one side is plane, is contacted with the axial plane of 5 upper section of slitter shaft, and limitation slitter shaft 5 is with respect on slitter shaft
The rotation of axle sleeve 8, while slitter shaft 5 is also limited relative to the rotation of turntable 9, therefore when slitter shaft 5 rotates, will drive turntable
9 and part rotates together thereon.
Cutter motor 24 is mounted on the side of cutter motor bracket 7, is sequentially connected by crank link mechanism and slitter shaft,
The crank link mechanism includes slitter shaft driving crank 6 and cutter connecting rod 21.Specifically: 24 output shaft of cutter motor and cutter
Axis driving crank 6 is fixedly connected, and slitter shaft driving crank 6 is rotatably connected with cutter connecting rod 21, cutter connecting rod 21 and slitter shaft
22 one end of connector is rotatably connected, and the other end of cutter shaft coupling 22 is rotatably set on slitter shaft 5.Slitter shaft connects
First 22 upper and lower sides respectively have the cutter shaft retaining ring 23 being fixed on slitter shaft 5, for limiting cutter shaft coupling 22 along slitter shaft 5
Axial moves up and down.When cutter motor 24 rotate when, will drive slitter shaft 5 up and down motion, due to cutter shaft coupling 22 with cut
It is face contact relationship between cutter shaft retaining ring 23, without limitation on the rotation of slitter shaft 5.Although passing through crank connecting link machine in the present embodiment
Structure is moved to cutter shaft coupling drive linear, but also be can be replaced any other suitable linear motion in other embodiments and passed
Motivation structure, such as leadscrew-nut mechanism, gear and rack teeth mechanism, sprocket wheel chain structure etc., or even cutter motor can be driven and be replaced
It is driven for cylinder or oil cylinder.
Cutter 27 is mounted in the groove of cutter supporter B26, and cutter supporter B26 leads in the sliding slot of cutter supporter A11
Cross the front-rear position of adjustment cutter supporter B26, the front-rear position (as shown in Figure 5) of adjustable cutter 27.Two stationary knife seats are led
One end of bar 25 is inserted on turntable 9, and the other end is inserted on the stationary knife seat 12 of top.Stationary knife seat 12 and stationary knife cover for seat plate 14 cooperate,
It is beneath to there is stationary knife receptacle plate 13 to hold, prevent stationary knife seat 12 from falling down, stationary knife seat 12 is installed in rotation on stationary knife cover for seat plate
Between 14 and stationary knife receptacle plate 13.Stationary knife cover for seat plate 14 is fixed on platen or in rack, and cutter motor mounting rack 7 is also installed
On the rack.Presser feet 15 is connect with presser feet cylinder 16, plays the role of pushing down template and cloth.The above-mentioned peace of cutter and stationary knife seat
Assembling structure is the prior art, therefore is no longer described in further detail.
When turntable 9 rotates, stationary knife seat 12 can follow rotation together, thereby realize on cutter 27 and stationary knife seat 12
Synchronized relation between stationary knife (not shown).
Below by taking above-described embodiment as an example, illustrate the working principle of rotation cloth cut device provided by the invention.When work, cut
Knife motor 24 controls the up and down motion of slitter shaft 5 by reciprocating rotation.There are two functions for up and down motion tool, first is that by making
Cutter 27 stretches out or does not stretch out stationary knife seat 12, and realization cuts cloth and do not cut the switching of cloth two states, determines second is that stretching out in cutter 27
After tool apron 12, the reciprocating motion to form cutter is rotated by high-frequency reciprocating, to generate the movement for cutting cloth.Rotating electric machine 1 passes through
The transmission of retarder and gear pair realizes the rotation of slitter shaft 5 and stationary knife seat 12, so as to complete cutting for various curve styles
Cloth function.
In the above-described embodiments, the transmission between rotating electric machine and slitter shaft is not limited only to the group of retarder and gear pair
It closes, such as retarder can be not provided with using decelerating motor or servo motor；The transmission ratio of gear pair can root
Adjusted according to actual needs, but also gear pair can be replaced with synchronous belt drive mechanism, the synchronous belt drive mechanism include belt,
Driving wheel and driven wheel.In addition, above-mentioned slitter shaft upper limit position block and lower position block are played as a kind of circumferential limiting component
It limits slitter shaft and rotates the effect for allowing its opposite the two to generate axial movement simultaneously relative to turntable and driven gear, wherein before
Stating two faces that limited block and slitter shaft contact with each other not necessarily is absolute plane, as long as can satisfy mutual cooperation, limit
The requirement being mutually shifted in circumferential direction processed.Other suitable circumferential limiting components, example can also be used in other embodiments
Such as limited block can be substituted by feather key, slitter shaft and above-mentioned driven gear or driven wheel and slitter shaft Upper shaft sleeve are realized by feather key
Connection, reach same purpose.
Above-mentioned technical proposal provided by the invention by by straight motion transmission device realize slitter shaft up and down motion, by
Rotating drive mechanism realizes the rotation of slitter shaft, and two kinds of movements are non-interference, realizes the synthesis of circular-rotation and linear motion,
So that rotation cloth cut device only needs two driving parts, and the 360 degree rotation for not needing driving part can be achieved with rotary cutting
Cloth function.This rotation cloth cut device is simpler compared to existing rotary cutting cloth mechanism structure, and cutter motor no longer needs
Axis around slitter shaft rotates, to greatly reduce the demand of installation space, not only manufactures and designs rack more convenient, also simple
The installation of sleeve mechanism is changed, the mechanical synchronization of cutter and stationary knife is especially realized while realizing double drive.
The above-described embodiments merely illustrate the principles and effects of the present invention, and is not intended to limit the present invention.It is any ripe
The personage for knowing this technology all without departing from the spirit and scope of the present invention, carries out modifications and changes to above-described embodiment.Cause
This, institute is complete without departing from the spirit and technical ideas disclosed in the present invention by those of ordinary skill in the art such as
At all equivalent modifications or change, should be covered by the claims of the present invention.
