The top net former
Technical field
The utility model belongs to footwear material paper machine technology field, is specifically related to be used in the top net former on the footwear material paper machine.
Background technology
Traditional long mesh paper making machine just relies on the wet end single face to dewater, and leans on the retention of filler and fiber fines of wire side page lower, and the high wire side contact of the page of formation is coarse, the two sides difference of paper greatly, the evenness of page is poor.Cause the relatively poor main cause of evenness to be, along with the carrying out of wet end dehydration, the concentration of wet web improves constantly, and the fleeces in the paper web gathers the degree aggravation, finally causes the evenness of paper relatively poor.Though adopt the forming table shake or add dandyprat, can partly improve the evenness of page, these methods can only be used on the low speed paper machine; When paper machine speed surpasses 250m/min, the shake of forming table and the employing of dandyprat will be restricted, because the dewatering elements of wet end generally all dewaters with chopping board; Shaking apparatus can not adopt, and dandyprat also must adopt the dandyprat of major diameter and band transmission, and it is high to make required precision; Roll surface is water dumping forward also, and roll body generally will be equipped with two groups.The installation site of dandyprat is before waterline in addition, and the mass dryness fraction of wet web is shaped near 6% basically at this moment, and dandyprat just plays the ornamenting effect to some big slightly floc sedimentations, can't resolve the big problem of paper two sides difference.
The utility model content
To the problem that prior art exists, the purpose of the utility model is to design a kind of technical scheme that is used in the top net former on the footwear material paper machine is provided.
Described top net former; Comprise frame; It is characterized in that being provided with in the described frame the anti-dewatering box of adjustable-height and angle; On described frame, set gradually outlet roller, adjuster, suction box, stretcher and guide-in roller in the direction of the clock, described outlet roller, adjuster, suction box, stretcher and establish forming web above the guide-in roller.
Described top net former is characterized in that described anti-dewatering box two ends connect first Motorized lift device and second Motorized lift device respectively.
Described top net former is characterized in that described outlet roller is fixed on the frame left side through the outlet roller support that is provided with, and connects the outlet roller lowering or hoisting gear on the described outlet roller support, and described outlet roller lowering or hoisting gear is fixedly installed on the frame.
Described top net former is characterized in that described adjuster is fixedly set in the upper left corner of frame, and described adjuster is provided with corrector roll.
Described top net former is characterized in that described suction box is provided with high pressure and moves sparge pipe.
Described top net former is characterized in that described stretcher is fixedly installed on the upper surface of frame, and described stretcher is provided with idler roller.
Described top net former is characterized in that described guide-in roller is fixed on the frame right side through the guide-in roller doctor blade holder that is provided with, and connects the guide-in roller lowering or hoisting gear on the described guide-in roller doctor blade holder, and described guide-in roller lowering or hoisting gear is fixedly installed on the frame.
Above-mentioned top net former, reasonable in design, compact conformation; Cooperate with footwear material paper machine, through downward, the double dewatering that makes progress, the more original intensity of more smooth, the inherent physical strength index of base plate outward appearance improved during the footwear of producing were used; Improve moulding evenness, improved production efficiency.

Fig. 1 is the structural representation of the utility model.
Among the figure: the 1-stretcher; The 2-idler roller; The 3-guide-in roller; The 4-outlet roller; 5-guide-in roller doctor blade holder; The anti-dewatering box of 6-; 7-first Motorized lift device; The 8-corrector roll; The 9-adjuster; The 10-high pressure moves sparge pipe; The 11-suction box; The 12-frame; 13-second Motorized lift device; 14-outlet roller lowering or hoisting gear; The last forming web of 15-; 16-guide-in roller lowering or hoisting gear; 17-outlet roller support.
The specific embodiment
Further specify the utility model below in conjunction with Figure of description.
As shown in the figure, the top net former comprises frame 12, frame 12 inner counter dewatering boxs 6.Anti-dewatering box 6 two ends connect first Motorized lift device 7 and second Motorized lift device 13 respectively, and first Motorized lift device 7 and second Motorized lift device 13 are fixed on the frame 12.Realize the adjusting of anti-dewatering box 6 height and angle through adjusting to first Motorized lift device 7 and second Motorized lift device 13.Set gradually outlet roller 4, adjuster 9, suction box 11, stretcher 1 and guide-in roller 3 on the frame 12 in the direction of the clock, and forming web 15 in outlet roller 4, adjuster 9, suction box 11, stretcher 1 and the guide-in roller 3 top windings.
Wherein outlet roller 4 supports through the outlet roller support 17 that is fixed on frame 12 left sides, and on outlet roller support 17, connects outlet roller lowering or hoisting gear 14, and outlet roller lowering or hoisting gear 14 is fixedly installed on the frame 12.Can realize the adjusting of outlet roller 4 height and angle through regulating outlet roller lowering or hoisting gear 14.Adjuster 9 is fixed on the upper left corner of frame 12, and adjuster 9 is provided with corrector roll 8.Suction box 11 and stretcher 1 are fixedly installed on the upper surface of frame 12.Suction box 11 has dehydration, and on suction box 11, is provided with high pressure and moves sparge pipe 10, can spray effect.Stretcher 1 mainly plays regulates the elasticity that goes up forming web 15, and stretcher 1 is provided with idler roller 2.Guide-in roller 3 supports through the guide-in roller doctor blade holder 5 that is fixed on frame 12 right sides, and guide-in roller doctor blade holder 5 is provided with scraper, and guide-in roller doctor blade holder 5 connection guide-in roller lowering or hoisting gears 16, and guide-in roller lowering or hoisting gear 16 is fixedly installed on the frame 12.Can realize the adjusting of guide-in roller 3 height and angle through regulating guide-in roller lowering or hoisting gear 16.
The l Water Paper that the utility model is carried secretly forming web carries out double side dewatering.Suction box 11 carries out vacuum dehydration with anti-dehydrator 6, through the adjusting of outlet roller 4, corrector roll 8, idler roller 2 and guide-in roller 3, l Water Paper is squeezed draw, and realizes dewatering in advance.The page wire side that obtains through the utility model processing is more level and smooth, and the two sides difference of paper is little, and the evenness of page is good.
