Description
Technical field
A kind of cheque paper production equipment of the present invention belongs to the machinery field.
Background technology
At present, the manufacturing of cheque paper all is will contain the dyestuff of anti-fake material and sandwich layer paper pulp earlier to stir to the dyeing of sandwich layer paper pulp usually, afterwards with the sandwich layer paper pulp that the dyed cheque paper of manufacturing paper with pulp.Correspondingly, the cheque paper production equipment of employing comprises the forming net that moves with slurry box, drying machine, gauze seperator, reel machine and closed circular circulation.Forming net moves when slurry box; Paper pulp stream in the slurry box forms pulp layer through dehydration on forming net, move through drying machine again and carry out drying, at the gauze seperator paper is separated with forming net at last; Cheque paper is wound on the reel machine, and forming net then circulates and moves to the slurry box place and utilize.The anti-fake material of the cheque paper of this device fabrication is dispersed in the middle of the sandwich layer, lacks anti-counterfeiting characteristic, and antifalse effect is not good.
For this reason; Industry has designed stacked cheque paper, and respective design be used to produce this stacked cheque paper cheque paper drench the spray production equipment, it is on existing cheque paper production equipment basis; Its slurry box is changed into the pure pulp of storing the no dyeing processing; And set up again in the back of slurry box the pouring spray machine that is used to drench the spray anti-fake material and storage have anti-fake material and with drench the paint box that the spray machine links to each other, forming net moves behind slurry box formation pulp layer, at first through filtering the spray machine; Drench spray and form one deck anti-fake material layer, move to subsequent drying machine, gauze separator for processing again.For adaptation has the cheque paper production demand of Multi-layer anti-counterfeit layer, can be on the forming net mobile route alternately be provided with a plurality of pulp layers and pouring spray machine, and respectively moulding pulp layer and false proof layer.
Though this false proof pouring spray production equipment can be produced stacked cheque paper, because the pouring nozzle keying frequency of pouring spray machine is limited, can't catches up with the production frequency of efficient paper making equipment, and cause cheque paper production efficiency lower.
In order to overcome above-mentioned technological deficiency; Multiple improvement technology has appearred at present; For example State Intellectual Property Office disclosed the patent application that a kind of application number is 200620017217, the mandate publication number is CN2931544, name is called a kind of cheque paper production equipment on August 8th, 2007, and this equipment comprises that forming net, at least one slurry box, at least one printing assembly, drying machine, gauze seperator, reel machine and storage that the closed circular circulation is moved contain the ink box of the printing ink of anti-fake material.Slurry box is provided with at least one slurry outlet that links to each other with slurry box; Said slurry outlet, printing assembly, drying machine, gauze seperator are arranged on the mobile route of forming net along the forming net moving direction successively; Said ink box links to each other with printing assembly to provide the printing ink that contains anti-fake material to printing assembly.
Through existing cheque paper production equipment is improved; Printing assembly will drench the spray machine and change printing assembly into, thereby can form false proof layer on the pulp layer surface, owing to can adapt to the production frequency of high speed paper making equipment through mode of printing; Thereby can effectively improve cheque paper production efficiency; But this equipment can only be applicable to the false proof of single-part stationery, can not produce stacked cheque paper, and the cheque paper anti-counterfeiting technology of coming out through this device fabrication is simple; Imitation is produced easily.
Summary of the invention
