The invention relates to a full-automatic high-speed pre-splitting
machine which comprises an unwinding part, a to-be-split complete roll, an unwinding correction device, an electronic cutter device,a before-splitting correction detection device, an automatic tape threading device, a manual splicing tape
workbench, a standby to-be-split roll, a rotating material rack device and a
workbench; the to-be-split complete roll, the standby to-be-split roll, an automatic pushing-out device, a winding auxiliary supporting device, a front winding tension device, a front winding dust removing device, afront detection
light source device, a winding pressing wheel device, a front width
measurement device and a winding and automatic tape splicing device are fixed to the
workbench from left to right sequentially; and a rear detection
light source device, a rear winding tension device, a rear winding dust removing device, a splitting and
cutting device, the electronic cutter device, the before-splitting correction detection device, a before-splitting correction device, a driving pressing roller device, a driving roller device, an unwinding tension device and the automatic tape threading device are fixed to the workbench sequentially. The full-automatic high-speed pre-splitting
machine is good in splitting effect and high in
automation degree, facilitates dust removal and has multiple functions.
