為了控制涂膠量,必須對(duì)涂膠設(shè)備進(jìn)行準(zhǔn)確的測(cè)量和調(diào)整。如果間隙太小,兩個(gè)滾筒會(huì)相互沖突,損壞網(wǎng)紋輥。因此,在調(diào)整時(shí)要謹(jǐn)慎,并要考慮到瓦楞紙輥受熱后的膨脹和變形,所以調(diào)整時(shí)不可貿(mào)然。
In order to control the glue quantity, it is necessary to measure and adjust the glue equipment accurately. If the gap is too small, the two rollers will conflict with each other and damage the anilox roller. Therefore, the adjustment should be careful, and take into account the expansion and deformation of the corrugating roll after heating, so the adjustment should not be rushed.

The gap between the two ends of the anilox roll and the press riveter roll is a part of the common one-sided machine with glue coating, which is necessary. There should not be a small mistake. Otherwise, because the number of glue coating will lead to the uneven water content of the two ends of the paperboard, the deformation of the paperboard is not common, and the paperboard will have single side twists and turns to the next process.

Apart from the gap between anilox roller and corrugating roller, apart from the necessary common, it is necessary to control the gap between the two rolls properly, the gap is too large to make the coating adhesion poor, forming part of the foam: because the corrugated roller and anilox roller line speed work.
整個(gè)瓦楞紙板的生產(chǎn)過(guò)程離不開(kāi)壓力,限制瓦楞紙板的壓力需求,紙與紙的粘合也需要壓力的合作才能結(jié)束。因此,適當(dāng)?shù)膲毫κ巧a(chǎn)瓦楞紙板的保證。正常情況下,瓦楞輥與壓輥之間的壓力應(yīng)控制在0.4mpa左右,但應(yīng)根據(jù)紙張的質(zhì)量敏感控制。木漿是指純木漿或比例較高的木漿。
The whole production process of corrugated board can not be separated from the pressure, which limits the pressure demand of corrugated board. The bonding of paper and paper also needs the cooperation of pressure to end. Therefore, proper pressure is the guarantee of producing high quality corrugated board. Under normal circumstances, the pressure between the corrugating roll and the pressing roll should be controlled at about 0.4MPa, but it should be controlled according to the quality sensitivity of the paper. High quality wood pulp refers to pure wood pulp or wood pulp with high proportion.
因此,松緊度越差,膠黏后越難滲透到紙纖維中。所以壓力應(yīng)該更大:低級(jí)的紙的質(zhì)量只是廢紙,再生紙,物理目標(biāo)差,如果壓力會(huì)損害紙張纖維甚粉碎,在生產(chǎn)實(shí)踐中應(yīng)在確保粘接強(qiáng)度的前提下紙的質(zhì)量和適當(dāng)?shù)目刂茐狠亯毫Α?/div>
Therefore, the worse the tightness, the more difficult it is to penetrate into the paper fiber after gluing. Therefore, the pressure should be greater: the quality of low-grade paper is only waste paper, recycled paper, and the physical target is poor. If the pressure will damage the paper fiber or even smash it, the quality of paper and the pressure of the press roll should be properly controlled under the premise of ensuring the bonding strength in the production practice.
網(wǎng)紋輥與雙層涂膠機(jī)膠輥之間的間隙應(yīng)相同。但在正常情況下,應(yīng)根據(jù)紙板兩層的厚度,將網(wǎng)紋輥與紙輥之間的間隙縮小0.30mm左右。因此,在上膠設(shè)備中調(diào)整各輥的間隙時(shí),必須謹(jǐn)慎、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以內(nèi)。
The gap between the anilox roller and the rubber roller of the double-layer gluer shall be the same. However, under normal circumstances, the gap between anilox roll and paper roll should be reduced by about 0.30mm according to the thickness of two layers of cardboard. Therefore, it is necessary to be careful and accurate when adjusting the clearance of the rollers in the sizing equipment. Strictly control the gluing amount together, and the gluing area shall be controlled within 1mm ~ 1.5mm of the ripple peak width.
否則不僅會(huì)增加生產(chǎn)成本,而且產(chǎn)品的質(zhì)量也不會(huì)令人滿意。間隙太大會(huì)使上膠和成型浪費(fèi):間隙太小會(huì)使瓦楞紙板接觸上膠輥太多,瓦楞紙板在上膠時(shí)超出實(shí)際的上膠要求。紙板在復(fù)合材料進(jìn)入干燥通道后,在重力輥的作用下將瓦楞紙壓扁而平整,使紙板變得又薄又軟。
Otherwise, not only the production cost will be increased, but also the quality of the products will not be satisfactory. The gap is too large to make glue and molding waste: too small gap will make the corrugated board contact the glue roller too much, and the corrugated board exceeds the actual glue requirements when gluing. After the composite material enters the drying channel, the corrugated paper is flattened and leveled under the action of the gravity roller, making the cardboard thin and soft.
