Abstract
The utility model discloses an anti-curling device for preventing curling of paper. The anti-curling device comprises two anti-curling device supports which are symmetrically arranged, wherein an anti-curling lining roller and an anti-curling roller are arranged between the anti-curling device supports; the central line of the anti-curling lining roller is parallel to that of the anti-curling roller; a swinging arm is arranged between each anti-curling device support and the anti-curling roller; an anti-curling square roller is arranged between the swinging arms; and the central line of the anti-curling square roller is parallel to that of the anti-curling roller. The anti-curling device is used for reversely stretching paper so as to inhibit curling of the paper, avoid the paper jam phenomenon and protect equipment. An anti-curling square shaft has a small included angle, so the strength of the anti-curling square shaft is higher than that of an optical shaft structure and the anti-curling function of the paper can be realized well.

Technical field
The utility model relates to the curling-resisting device that is used to prevent that paper from curling, and belongs to cross cutting, the indentation equipment of paper product industries, is specifically related to web platen indentation die-cutting machine.
Background technology
Mould cutting machine is hydraulic cutting presser, numerical control stamping machine again; Be mainly used in cross cutting, impression and gold stamping operation, applying, the waste discharge automatically of more corresponding non-metallic materials, non-drying glue, EVA, double faced adhesive tape, electronics, mobile phone rubber cushion etc.; Mould cutting machine utilizes steel knife, five metals mould, steel wire; Apply certain pressure through coining plate, printing or cardboard are rolled be cut into definite shape.Except cross cutting, also requirement can be gold stamping and automatic clear useless.Numerical control die cutting machine with the Kunlun Mechanology Inc. is an example, from paper feeding, cross cutting/gold stamping, fits to the upper and lower part/waste discharge, and last collection/cut all completion automatically is reliable and stable.Mould cutting machine forms different class, is directed against multiple printing packaging product equipment family covering extensive fields, wide in variety in China as the major equipment of seal back package printed matter processing, has satisfied domestic demand to equipment basically.It will be the best cross cutting mode of printing packaging product in enormous quantities that circle is pressed circle line cross cutting.Line printing packaging equipment such as flexographic printing manufacturing line, form printing machine, fluting board printing slotting die-cutting machine, cycle type pressure-sensitive adhesive trade mark printer, intaghlio printing die-cutting production line have been used at present.Along with the printing development of science and technology, the raising of the processing technology level of especially round cross cutting cylinder, the field of application of circle cross cutting will be more extensive, and the production efficiency of cross cutting will further improve.Along with the fast development of printing packaging industry, the scale of enterprise constantly enlarges.The application market of full-automatic flat-press flat-die cutting machine will constantly enlarge.The wheel volume of production and marketing of changeing satellite-type label printing machine and flexographic presses increases efficiently, printing and connect the backward production facilities that machine circular pressing and cutting production efficiency is higher than intermittently printing, intermittence concora crush cross cutting far away.During mould cutting machine work operation, the paper in reel paper has curl characteristics, occurs the phenomenon of curling during conveying easily, influences the paper feeding precision.Can cause paperboard when serious, cause equipment downtime.
The utility model content
The purpose of the utility model is to overcome the shortcoming and defect of above-mentioned prior art, is provided for preventing the curling-resisting device that paper curls, and this curling-resisting device effect is that paper is carried out negative drawing, suppresses paper and curls, and avoids the paper paper jam phenomenon preventive device to occur.
The purpose of the utility model realizes through following technical proposals: be used to prevent the curling-resisting device that paper curls; Comprise two symmetrically arranged contrary flexure device bearings; Be provided with contrary flexure lining roller and contrary flexure roller between the said contrary flexure device bearing, it is parallel with the line of centers of contrary flexure roller that contrary flexure serves as a contrast the line of centers of roller, is provided with swing arm between every contrary flexure device bearing and the contrary flexure roller; Be provided with contrary flexure side's roller between the said swing arm, and the line of centers of contrary flexure side's roller is parallel with the line of centers of contrary flexure roller.
The sidewall of said contrary flexure side roller is four faces, and the angle between the adjacent wall is 30 ° to 80 °.
Angle between the said contrary flexure side roller adjacent wall is 60 °.
Said swing arm is provided with some through holes, and the two ends of contrary flexure lining roller, contrary flexure roller and contrary flexure side's roller are separately positioned in the cooresponding through hole.
Said contrary flexure device bearing is provided with through hole, is provided with installation shaft in the through hole, and an end of installation shaft is connected with swing arm after passing through hole.
In sum; The beneficial effect of the utility model is: this curling-resisting device effect is that paper is carried out negative drawing, suppresses paper and curls, and avoids the paper paper jam phenomenon to occur; Preventive device; And the angle angle is less on the contrary flexure square shaft, and the intensity ratio optical axis structural strength of contrary flexure square shaft is strengthened, and makes paper can better realize the contrary flexure function.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Mark and corresponding parts title in the accompanying drawing: 1-installation shaft; 2-swing arm; 3-through hole; 4-contrary flexure device bearing; 5-contrary flexure side roller; 6-contrary flexure roller; 7-contrary flexure lining roller; 8-through hole.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is done further to specify, but the embodiment of the utility model is not limited only to this.
Embodiment:
As shown in Figure 1; Be used to prevent the curling-resisting device that paper curls, comprise two symmetrically arranged contrary flexure device bearings 4, be provided with contrary flexure lining roller 7 and contrary flexure roller 6 between the said contrary flexure device bearing 4; The line of centers of contrary flexure lining roller 7 is parallel with the line of centers of contrary flexure roller 6; Be provided with swing arm 2 between every contrary flexure device bearing 4 and the contrary flexure roller 6, be provided with contrary flexure side's roller 5 between the said swing arm 2, and the line of centers of contrary flexure side's roller 5 be parallel with the line of centers of contrary flexure roller 6.This curling-resisting device is installed on the cross cutting, indentation equipment of paper product industries, specifically is installed on the web platen indentation die-cutting machine.
