Be equipped with a photoelectric sensor 26, described sprocket wheel and photoelectric sensor 26 are connected with a controller, described controller also with
One audible-visual annunciator is connected.
The operation principle of feed arrangement of the present invention is as follows:
First according to the size of printing, position of the regulation positive stop 5 on slide rail 22, and consolidated by fastener
It is fixed, then the printing that heap is folded is placed between support platform 1 and top, positive stop 5 and the backstop 6 of lifting pin 3, initially
Under state, above the supporting surface of the jacking of lifting pin 3 to support platform 1 so that printing close to positive stop 5 half by jack-up, this
When, the main by weight of printing is concentrated on lifting pin 3, is almost separated from each other between driving pulley 2 and printing, therefore, and driving is slided
Wheel 2 can not drive the printing of the bottom to feed, when needing charging, and jacking cylinder 4, which is shunk, causes lifting pin 3 to decline, and works as jacking
When bar 3 is dropped to below the supporting surface of support platform 1, the printing of driving pulley 2 and the bottom is completely attached to, and driving pulley 2 drives
The printing of the dynamic bottom realizes charging, when the printing of the bottom, which is fed, to be completed, and jacking cylinder 4, which extends, make it that lifting pin 3 is upward
Above jacking to the supporting surface of support platform 1, then repeatedly aforesaid operations, so as to realize the continuous quick feeding of printing.
The operation principle of feeding regulating device of the present invention is as follows:
Printing enters feeding regulating device from feed arrangement, first according to the thickness of printing, is driven by driving handle 31
Screw rod 30 is rotated, so as to adjust the height of support frame 8, during work, printing is conveyed by conveyer belt 7, the cunning on pole 10
Printing is pressed on conveyer belt 7 by wheel 13 by torsional spring 12, so as to effectively prevent the skew of printing, hereafter printing enters branch
The rear of platform 1 is supportted, subsequent treatment is carried out after driving adjustment sheet 15 printing product of adjustment sheet cylinder 16 accurately adjust.
The operation principle of inventive die fixing device is as follows:
Printing enters from feeding regulating device carries out crush-cutting processing in die-cutting machine body 17, can be by mould when dismantling mould
Tool fixed plate 19 is skidded off out of die-cutting machine body 17, and is fixed by latch 21, and mould is fixed this makes it possible to convenient
Mould on plate 19 is maintained, meanwhile, mould can also be pulled down from mold fixed plate 19 and be changed;Installing
When, latch 21 only need to be unclamped, the mold fixed plate 19 that will be equipped with mould slips into die-cutting machine body 17 from mould installion mouthful 18.
The operation principle of discharging mechanism of the present invention is as follows:
Printing enters discharging mechanism after the die treatment in die-cutting machine, and in an initial condition, object disposing platform 27 is in
Higher position, when photoelectric sensor 26 has monitored that printing is fallen on rack 29, controller drive sprocket is rotated so that
Object disposing platform 27 moves down certain distance, will fill whne rack 29, object disposing platform 2 close to die-cutting machine body 17 bottom when,
Controller control audible-visual annunciator alarm, reminds staff to change rack 29.
