Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, the detailed description of the invention of the present invention is described in further detail.Following example are used for illustrating the present invention, but are not limited to the scope of the present invention.
Below with reference to Fig. 1 to Fig. 8, the present invention will be described.
The folding device suitable for reading of a kind of paper bag machine, including rotating opisthotonos bottom roller 1, inhales paper wheel 2, pressure roller 3, and paper is being inhaled between paper wheel 2 and opisthotonos bottom roller 1 and carried between pressure roller 3 and opisthotonos bottom roller 1；Suction paper wheel 2 and pressure roller 3 are positioned at the upside of opisthotonos bottom roller 1, and during work, paper is introduced between suction paper wheel 2 and opisthotonos bottom roller 1, then exports between pressure roller 3 and opisthotonos bottom roller 1.
Inhaling paper wheel 2 and be provided with the first suction paper portion 21, first inhales paper portion 21 treats opisthotonos part for sticking paper bag front end, and first to inhale paper portion 21 be to be arranged to inhale paper and take turns the first suction hole on 2, and its sticking by the way of air-breathing treats opisthotonos part.
Opisthotonos bottom roller 1 is provided with the second suction paper portion 11, second inhales paper portion 11 for sticking paper except treating invayination other parts exceptionally, and draw paper and rotate with it and move, second to inhale paper portion 11 be the second suction hole being arranged on opisthotonos bottom roller 1, and its sticking by the way of air-breathing treats the invayination of paper other parts exceptionally.
Opisthotonos bottom roller 1 is elongated roller, and its two ends are connected in frame, and the inside of opisthotonos bottom roller 1 is cavity, and the second suction hole is arranged on opisthotonos bottom roller 1 and connects with cavity, and the air in cavity is drawn in air pump work, makes the second suction hole produce holding force.Second suction hole is provided with multiple, and arranges in a row along opisthotonos bottom roller 1 axial direction interval.
One air-breathing beaming roller 4 in parallel is set on the upside of opisthotonos bottom roller 1, air-breathing beaming roller 4 is internal is hollow-core construction, the internal cavities of air-breathing beaming roller 4 is connected with air pump, inhale paper wheel 2 to be connected on air-breathing beaming roller 4, inhale paper wheel 2 and be provided with the first suction hole that the internal cavities with air-breathing beaming roller 4 connects, the air in cavity is drawn in air pump work, makes the first suction hole produce holding force.Inhale paper wheel 2 and be arranged at intervals with multiple along air-breathing beaming roller 4 axial direction.
nullDuring work，Carry out paper (one broken line trace of front end extrusion of paper of overvoltage stria operation，The front end making paper is formed treats opisthotonos part) enter and inhale between paper wheel 2 and opisthotonos bottom roller 1，Now，Inhale paper wheel 2 the first suction hole elder generation sticking paper treat opisthotonos part，Paper treat opisthotonos part with inhale paper wheel 2 rotation bend，When paper treat opisthotonos part all from inhale paper wheel 2 and opisthotonos bottom roller 1 between through later，The second suction hole on opisthotonos bottom roller 1 forwards to inhale between paper wheel 2 and opisthotonos bottom roller 1，Second suction hole sticking paper treat invayination other parts exceptionally，Second suction hole sticking paper and is moved，What the first suction hole unclamped paper simultaneously treats opisthotonos part，At this moment the front end of paper is in treating that opisthotonos part is to treating invayination other part bendings exceptionally，And carry out between entrance pressure roller 3 and opisthotonos bottom roller 1 therewith rolling over backfin operation (including pressure and the action of folding) suitable for reading，Complete to roll over operation suitable for reading.
Can also arrange rubber wheel 5 on air-breathing beaming roller 4, rubber wheel 5 coordinates conveying paper with opisthotonos bottom roller 1, improves stability and the efficiency of paper sheet delivery, and rubber wheel 5 is arranged on two and inhales between paper wheel 2.
Being circumferentially with annular groove 6 along it on opisthotonos bottom roller 1, annular groove 6 is provided with a plurality of, and lays respectively between two the second suction holes, and annular groove 6 enters between paper and opisthotonos bottom roller 1 for air, prevents paper adsorption on opisthotonos bottom roller 1.
In order to prevent paper enter carry out between pressure roller 3 and opisthotonos bottom roller 1 rolling over backfin operation suitable for reading before treated opisthotonos part reinstatement state by the first suction hole sticking bending, can arrange between paper wheel 2 and pressure roller 3 treating that opisthotonos part carries out the mechanism of gear pressure (gear pressure includes the action stopping and pressing) after bending inhaling.
Arranging pressing board 7 at the paper inlet of pressure roller 3 and opisthotonos bottom roller 1, pressing board 7 treats opisthotonos part for keeping off after platen opens bending, stops it to rebound.Pressing board 7 is an elongated plate body arranged along opisthotonos bottom roller 1 axial direction.
Spacing between pressing board 7 and opisthotonos bottom roller 1 is adjustable setting, and this arranges scalable pressing board 7 and treats the size of opisthotonos part gear pressure effect.Between pressing board 7 and opisthotonos bottom roller 1 the nearlyest pressing board 7 treat opisthotonos part gear pressure effect the biggest, between pressing board 7 and opisthotonos bottom roller 1 the biggest pressing board 7 treat opisthotonos part gear pressure effect the least.
Pressing board 7 and the adjustable setting of opisthotonos bottom roller 1 spacing, can realize regulation by various simple mechanisms, shown in the drawings of a kind of structure being regulated pressing board 7 by screw rod 8.
Pressing board 7 is big with the contact area of paper, is suitable for carrying out thicker paper keeping off press operation.
Dial paper slip 9 inhaling to be equipped with between paper wheel 2 and pressure roller 3, dial paper slip 9 and treat opisthotonos part for keeping off after platen opens bending, stop it to rebound.Dialling paper slip 9 is strip, and its one end is fixing to be connected, and the other end is arranged near opisthotonos bottom roller 1.
Dialling spacing between paper slip 9 and opisthotonos bottom roller 1 is adjustable setting, and this arranges scalable and dials paper slip 9 and treat the size of opisthotonos part gear pressure effect.Dial the most closely dial between paper slip 9 and opisthotonos bottom roller 1 paper slip 9 treat opisthotonos part gear pressure effect the biggest, dial dial the most greatly between paper slip 9 and opisthotonos bottom roller 1 paper slip 9 treat opisthotonos part gear pressure effect the least.
