Description

Multichannel slicing transfer system and method Technical Field The invention belongs to the field of medical dressing production equipment, and particularly relates to a multichannel slicing transfer system and a multichannel slicing transfer method. Background After the medical dressing (foam dressing and hydrogel dressing) is processed by a compounding machine and a slitting machine, the medical dressing (foam dressing and hydrogel dressing) is required to be conveyed to a packaging system for packaging treatment. Along with the rapid upgrading of production equipment, the production speed of the medical dressing is greatly improved. The medical dressing output from the dividing and cutting machine is relatively large in quantity, and the discharging frequency is relatively high. The operation speed of the output belt of the medical dressing dividing and cutting machine is higher, the arrangement of the medical dressing is denser, and if the medical dressing is directly transported to a packing system for packing, the packing speed of the packing machine cannot be matched with the transportation speed of the output belt of the medical dressing dividing and cutting machine. It is therefore desirable to design a transfer mechanism for distributing a medical dressing into multiple lanes for delivery in order to increase the number of balers and thus the baling efficiency. The prior equipment capable of completing the transfer comprises a manipulator or other transfer clamps, but has the common problems that the transfer speed is not fast enough, the frequency of the reciprocating operation of the manipulator or other transfer clamps is too low when the manipulator or other transfer clamps work, and the medical dressing can not be rapidly distributed.
