It the utility model is related to field of textile machinery, more particularly to a kind of fabric cutter.
In field of textiles, it is often necessary to by a Cloth Cutting into some lengths of cloth, now, it is general using it is artificial cut with
Machinery cuts two methods, and artificial cutting needs more people's operations and efficiency is low, and production cost is too high；The existing machinery that cuts is entering
Often the cloth come is so cut out when row Cloth Cutting because the remote reason such as traction causes the tightness of cloth different
Will dimensionally gap.
Utility model content
In order to solve the above technical problems, this practicality proposes following technical scheme：

Son is connected to travelling carriage guide rail, and the storage rack is provided with roller B close to the side of workbench.
Preferably, the mainframe also includes traction speed reducer for servo motor, travelling gear, line slide rail, cut-off knife servo
Motor reducer and cut-off knife driving chain sprocket, the cut-off knife are connected to line slide rail, and the line slide rail passes through cut-off knife driving chain sprocket
Cut-off knife speed reducer for servo motor is connected to, the traction roller is connected to traction speed reducer for servo motor by travelling gear.
Preferably, the storage rack also includes spacing proximity switch, storing roller mount, directive wheel and guide rod, the storage
Material roller is connected to storing roller mount, and the storing roller mount is connected to the travelling carriage guide rail, the counterweight by directive wheel
Block is connected to the guide rod.
Preferably, the storage rack is sequentially provided with roller C, roller D, roller E and roller from the roller B away from workbench
Sub- F, the roller C, roller D, roller E and roller F connect point into line is less than the roller F in M types, the height of the roller C.
Preferably, the quantity of the pneumatic pressure roller and cylinder is equal with traction roller.
The utility model contrast prior art can realize following beneficial effect：The utility model realizes cloth by balancing weight
Tightness during cutting is identical, realizes that the cut size of cloth is equal with this；The utility model is simple in construction, automatically
Change degree is high, easy to operate, and production efficiency is high.

Such as Fig. 1, the utility model is made up of mainframe 1, workbench 2 and the three parts of storage rack 3, mainframe 1, work
Platform 2 and storage rack 3 are used as medium by cloth and are sequentially connected, and the mainframe 1 includes traction speed reducer for servo motor 11, gas
Cylinder 12, pressure roller 13, traction roller 14, travelling gear 15, cut-off knife 16, line slide rail 17, cut-off knife driving chain sprocket 171, cut-off knife servo
Motor reducer 18 and roller A19, such as Fig. 4 and Fig. 2, traction speed reducer for servo motor 11 is connected with the mainframe 1, it is described
Traction speed reducer for servo motor 11 is connected to the traction roller 14, the master of the top of traction roller 14 by travelling gear 15
Pneumatic pressure roller 13 is provided with frame 1, the pneumatic pressure roller 13 is connected to cylinder 12, and 1 is connected with cut-off knife servo in the mainframe
Motor reducer 18, the cut-off knife speed reducer for servo motor 18 is connected to the cut-off knife 16 by cut-off knife driving chain sprocket 171, described
Cut-off knife 16 is between traction roller 14, traction roller 14 at least 2 and the corresponding setting, and the one of the mainframe 1
Side is provided with roller A19；Such as Fig. 3 and Fig. 1, the storage rack 3 includes roller B30, roller C31, roller D32, sprocket wheel 33, roller
E34, travelling carriage guide rail 35, spacing proximity switch 36, balancing weight 37, guide rod 38, storing roller mount 39, storing roller 310, roller
