Woven bag separate machine
Technical field
The invention belongs to woven bags to manufacture processing technique field, and in particular to a kind of woven bag separate machine.
Background technology
The processing of woven bag is usually that plastics silk thread is first woven into continuous tubular band, then again cuts out tubular band
It is cut into woven bag size, and one of end is sutured.Tubular band (hereinafter referred to as material strip) needs after working out
It is first wound, in order to transport and store.Therefore it before dividing material strip needs that first material volume is unfolded, it is in the prior art to unreel
Device is generally unable to control and unreels speed, when the feed speed of unwinding device is more than the material strip feed speed of segmenting device, just
Material strip can be caused to overstock, to make material strip generate fold, influence woven bag Forming Quality.In addition, material strip in the prior art point
It cuts the material strip after device segmentation generally to pile up in a mounting bracket, with the stacking of material strip, thickness is increasing, leads to material strip
Heap top surface is significantly larger than the top surface of segmenting device discharge port, so that segmenting device can not normally discharge, it is therefore desirable to high frequency time
Transfer carriage on material strip, labor intensity of operating staff is larger.
