The paste box folding machine of automatic school paper patch window

Technical field

This utility model relates to a kind of paper (box) case production machinery, refers in particular to and before uncoated paper window pad pasting, it can be carried out position correction and implement the device of patch window on this machine.

Background technology

Sticking with paste box folding machine is a kind of machine that by the uncoated paper after color printing, lemon paper, cross cutting, can make paper (box) case after carrying out the operations such as autosizing, the hook end, folding, joint. for adapting to paper (box) case outward appearance and to Item Information visualization requirements in case, a kind of paper (box) case with visual windows is widely applied in product outsourcing in recent years, for ensureing paper (box) case overall sealing performance, it is both needed to when such paper (box) case is made on uncoated paper window and pastes layer of transparent fenestrated membrane, the patch window operation of uncoated paper window is usually completed by special window adhering machine by existing carton making process before uncoated paper enters and sticks with paste box folding machine, though this special window adhering machine can complete the pad pasting to uncoated paper window, but this machine still suffers from some shortcomings when actually used: on the one hand, because this machine is stand-alone machine, for supporting with different size paste box folding machine, it certainly will should adopt corresponding type, the production of different types of machines and select actual supporting time very inconvenient, and the uncoated paper posting fenestrated membrane yet to rely on and manually be transferred on follow-up paste box folding machine, this makes again production automation degree reduce, have impact on the production efficiency of machine, on the other hand, uncoated paper school is exactly based on what multiple tracks correcting unit was gradually completing by existing window adhering machine, multiple tracks correcting unit arranges and not only makes machine fuselage long, too much take up room, and uncoated paper correction channel is longer, school chart speed degree is relatively slow, have impact on production of machinery speed, there will naturally be and take up room greatly, the slow-footed defect of school paper, another aspect, on existing window adhering machine, cloth glue mode used " sticks with paste cylinder storing nothing more than traditional, tab (s) viscose glue " and the mode of " runner gluing ", wherein " stick with paste cylinder storing, tab (s) viscose glue " though this cloth glue mode can realize uncoated paper window edge is carried out cloth glue, but it is operationally that on random device, set induction system is constantly transported forward because of uncoated paper, then the longitudinal tab (s) by being arranged on machine can be conveniently implemented in the cloth glue of window longitudinal edge, and the cloth glue on window transverse edge, then need by setting up the synchronous cross motor system Tong Bu with uncoated paper on machine, horizontal glue tab (s) is arranged in this motor system, and follow this motor system one and act as and be longitudinally travelled, horizontal glue tab (s) completes the cloth glue operation at window transverse edge in the process, and after horizontal glue operation completes, horizontal glue tab (s) pursuit movement system one can act as Quick return again, return to cloth glue starting point, to carry out the cloth glue of next uncoated paper window, this synchronous cross motor system not only structure is complicated, manufacturing cost is high, when practical application, adjustment and maintenance is all cumbersome, and runner gluing method is the cloth glue pattern according to window, side, rubber tire outer ring makes same pattern then hollowed out by cloth Jiao Chu, rubber tire abdominal cavity stores glue, uncoated paper ceaselessly forward rectilinear conveying during work, rubber tire is contacted with uncoated paper by the mode rotated, rubber tire intraperitoneal glue spills at the wheel rim place of hollowing out and completes cloth glue on the cloth tree lace of uncoated paper window periphery, this cloth glue mode is compared and sticks with paste a storing, tab (s) viscose glue mode, its structure is relatively easy, can disposable realize window in length and breadth two to cloth glue, but because cloth rubber tire used in runner gluing method is generally overall structure, its width can not adjust, and various different its window transverse width dimension of carton is not quite similar, when then uncoated paper window width changes whenever aborning, just need the cloth rubber tire of customized respective width specification, so it is formed for a lot of

that uncoated paper water suction is too fast, have a strong impact on the patch viscosity of glue, very easily produce the phenomenon of fenestrated membrane degumming,Another further aspect, on existing window adhering machine, the fenestrated membrane for pasting window is supplied by for membranous system, this confession membranous system generally includes the film roll being installed on paper spool with certain damping, the fortune letterweight roller of traction paper membrane, with the hand papercutter cutting off paper membrane, transport paper-mulching under the traction rolling of letterweight roller at a pair during work live uncoated paper window and follow uncoated paper movement forward together, when paper membrane length reaches to cover window Len req, paper tape is cut by hand papercutter action, this imposing at paper disc end damps by transporting the mode that letterweight roller traction tension fenestrated membrane carries out cutting, though the cutting to paper tape can be realized, but putting on the damping on paper disc during because of paper feeding pressure roller draw can not be excessive, paper feeding pressure roller otherwise can be caused to skid, affect the normal transport of uncoated paper and film, so cutting film moment impulse force when cutting film because of hand papercutter very easily causes relatively greatly paper disc to skid and the overshoot that rotates, stretch tight and draw the paper tape between paper disc and paper feeding pressure roller to loosen, cut impulse force during hand papercutter cut paper to weaken because paper loosens, form cut paper not agile, institute's cut paper limit is not neat, the length of cut fenestrated membrane will be different in size, after causing patch window, paper membrane is from window, the quality problems that lower limb width does not wait, hand papercutter always occupies certain space in frame again, certain distance is always there is in its paper of the paper tape then cut between fortune letterweight roller, then paper can only ride over and be brought between fortune letterweight roller by uncoated paper on the uncoated paper of viscose glue, before fenestrated membrane is glued by institute's viscose on uncoated paper and pulls in the process, just can produce unavoidably between fenestrated membrane and uncoated paper to skid, very easily cause uncoated paper window top edge width narrow or dew core, and form substandard products or waste product, therefore cut film feeding structure used by existing laminator to there will naturally be paper membrane when cutting film and stretch tight not tight, cut film not agile, paper membrane can not be transmitted directly to the defect between fortune letterweight roller. uncoated paper pasted window arrange with sticking with paste foldable type extension set platform in view of existing, and some problems deposited on existing window adhering machine, each equipment manufacturer all making every effort to design one and can be united two into one by two machines, possesses fuselage length short, can to uncoated paper Fast Correction, do not limit to uncoated paper wide cut and thickness, conveniently cloth rubber tire width can be adjusted, and cloth glue amount foot, tree lace is uniform, paper membrane can be kept when cutting film not loosen, and paper membrane can be fed directly to the school paper patch window device between fortune letterweight roller.
