為了控制涂膠量,應(yīng)對原施膠設(shè)備進(jìn)行準(zhǔn)確的計量和調(diào)整。間隙過小會使兩輥發(fā)生沖突,損壞涂布輥,形成不可修復(fù)的效果,無法正常生產(chǎn)。因此,在調(diào)整時要謹(jǐn)慎,并要考慮到膨脹后的瓦楞紙輥受熱變形,所以千萬不要急于調(diào)整。
In order to control the amount of sizing, the original sizing equipment should be accurately measured and adjusted. Too small gap will make the two rolls conflict, damage the coating roll, forming an irreparable effect, unable to normal production. Therefore, it is necessary to be careful when adjusting, and consider the thermal deformation of the expanded corrugating roll, so do not rush to adjust.
在單面印刷機(jī)膠涂層的一部分膠涂布輥和刮輥兩端之間的差距是必要的,不能有一點錯誤,或者因為膠的數(shù)量會導(dǎo)致大量的紙板的含水量不均勻,使紙板兩端變形是不常見的,紙板會發(fā)生單邊曲折,到下一個過程。
The gap between a part of the glue coating roller and the two ends of the squeegee roller of the single-sided printing machine is necessary, and there should be no mistake, or because the amount of glue will lead to a large number of uneven water content of the paperboard, so that the deformation of the two ends of the paperboard is not common, and the paperboard will occur unilateral bending, to the next process.
膠輥和瓦楞輥之間的差距除了必要的兩端的常見,但也要控制適當(dāng)?shù)膬奢佒g的差距,差距太大了,讓壞膠涂層,形成泡沫的一部分,壞附著力:因為瓦楞輥,膠輥的線速度的工作并不常見。
The gap between cots and corrugating rollers is common except for the necessary ends, but it is also necessary to control the gap between the two rolls properly. The gap is too large for the bad glue coating to form part of the foam and bad adhesion: the corrugation rollers and the cots are not very common.
整個生產(chǎn)過程中瓦楞紙板與壓力是不可分割的,限制了瓦楞紙板的壓力需求,紙張與紙張的粘合也要求壓力配合能力結(jié)束。因此,適當(dāng)?shù)膲毫κ巧a(chǎn)瓦楞紙板的重要保證。正常情況下,瓦楞紙輥與壓力輥之間的壓力應(yīng)控制在0.4mpa左右,但應(yīng)根據(jù)紙張質(zhì)量敏感處理。紙張的質(zhì)量等級是由純木漿或含較高比例木漿的材料制成的。
In the whole production process, corrugated board and pressure are inseparable, which limits the pressure demand of corrugated board, and the adhesion of paper and paper also requires the end of pressure matching ability. Therefore, appropriate pressure is an important guarantee for the production of high-quality corrugated board. Under normal circumstances, the pressure between the corrugating roll and the pressure roll should be controlled at about 0.4MPa, but it should be handled according to the paper quality sensitivity. The quality grade of paper is made of pure wood pulp or materials containing a higher proportion of wood pulp.
因此,松緊度越嚴(yán)格,膠水越難滲透到紙纖維中。所以壓力應(yīng)該更:和等級材料是廢紙,再生紙,物理目標(biāo)是可憐的,如果壓力太多會損害紙纖維,紙會被打破,生產(chǎn)實踐中應(yīng)該按照論文的質(zhì)量,以確保粘接強(qiáng)度和適當(dāng)?shù)目刂茐狠伒膲毫Α?/div>
Therefore, the tighter the tightness, the more difficult it is for the glue to penetrate into the paper fiber. So the pressure should be more: and the low-grade material is waste paper, recycled paper, the physical goal is poor, if the pressure is too much will damage the paper fiber, the paper will be broken, the production practice should be in accordance with the quality of the paper, to ensure the bonding strength and appropriate control of the pressure roller.
滾子和刮墨刀之間的空間應(yīng)該是相同的,兩端應(yīng)該沒有錯誤。但在正常情況下,根據(jù)紙板兩層的厚度,膠輥與紙輥之間的距離應(yīng)減少約0.30mm。因此,在調(diào)整上膠設(shè)備各滾筒間隙時,要小心、準(zhǔn)確。一起嚴(yán)格控制上膠量,上膠面積控制在波紋峰寬度1mm~1.5mm范圍內(nèi)。
The space between the roller and the doctor blade should be the same, and there should be no errors at both ends. But under normal circumstances, according to the thickness of two layers of cardboard, the distance between the cot and the paper roll should be reduced by about 0.30mm. Therefore, it is necessary to be careful and accurate when adjusting the gap between the rollers of the gluing equipment. Strictly control the gluing amount together, and the gluing area shall be controlled within the range of 1mm ~ 1.5mm of the ripple peak width.
否則,不僅會增加生產(chǎn)成本,而且產(chǎn)品的質(zhì)量也不會令人滿意??臻g過大會使膠水質(zhì)量差而浪費:空間過小會使瓦楞紙板過多地接觸膠輥而使瓦楞紙板在涂膠量上超出實際需要。當(dāng)板料進(jìn)入干燥復(fù)合后,在重力滾輪的作用下會使瓦楞紙板變平而塌陷,使板料變得又薄又軟。
Otherwise, not only the production cost will be increased, but also the quality of the product will not be satisfactory. Too much space will lead to poor glue quality and waste: too little space will make the corrugated board contact the rubber roller too much and make the amount of glue applied on the corrugated board exceed the actual needs. When the board enters the drying compound, under the action of the gravity roller, the corrugated board will become flat and collapse, making the board thin and soft.
