1、新鑄制的膠輥不宜馬上投入使用
1. The newly cast cots should not be put into use immediately.
由于新鑄制的膠輥內(nèi)部結(jié)構(gòu)還不夠穩(wěn)定，若立即投入使用，容易降低使用壽命。故剛出筒的新膠輥應(yīng)放置一段時間，使膠輥接觸外界環(huán)境溫濕度后，保持相對的穩(wěn)定狀態(tài)，這樣可以增加膠體的堅韌性，從而提高耐用效果。
Because the internal structure of the newly cast cots is not stable enough, if put into use immediately, it is easy to reduce the service life. Therefore, the new cots just out of the drum should be placed for a period of time, so that the cots keep relatively stable after contacting with the outside environment temperature and humidity, so as to increase the toughness of the colloid, thereby improving the durability effect.
2、閑置膠輥的正確存放
2. Proper storage of idle Cots
待用的膠輥應(yīng)清洗干凈后，用塑料薄膜把膠體封包起來，存放在陰涼、干燥、通風的場所，并呈垂直或水平狀態(tài)，切不可幾根隨便堆放在一塊或順手豎靠在墻壁旁，以免使膠體受到不應(yīng)有的損失，也要避免與酸、堿、油類和尖硬物質(zhì)等一起存放，以免腐蝕、碰傷膠輥。膠輥保存2——3個月后，應(yīng)把它改變一下方向，以防長期一個方向放置發(fā)生彎曲變形，并注意防止軸頭部分生銹。廢舊的膠輥在送往加工澆鑄的運輸過程中，切忌亂扔亂放亂壓或重壓，保持輥芯不偏芯、不彎曲，以確保輥芯正常利用。
After the cots to be used should be cleaned, the colloids should be encapsulated with plastic film and stored in a cool, dry and ventilated place in a vertical or horizontal state. Several cots should not be stacked randomly in a single place or placed on the wall, so as not to cause undue loss of colloids, but also to avoid acid, alkali, oil and sharp points. Hard materials are stored together to avoid corrosion and damage to cots. After 2 - 3 months of storage, the cots should be changed to prevent bending deformation in one direction for a long time, and to prevent rust in the head of the shaft. In order to ensure the normal use of the roll core, the scrap cots should not be thrown randomly or pressed heavily during the transportation to the processing and casting, and the core should not be deflected or bent.
3、膠輥軸頭、軸承應(yīng)保持良好的潤滑
3. Good lubrication should be maintained for cot head and bearing.
我們知道，膠輥軸頭、軸承的精度直接如何，直接影響到傳墨、布墨的效果。若潤滑不良引
We know that the accuracy of cot shaft head and bearing directly affects the effect of ink transmission and printing. If the lubrication is not good
起膠輥軸頭，軸承的磨損、間隙，必然導(dǎo)致印刷墨色不均勻的弊病。同時也會因跳膠、滑膠
The wear and clearance of roller head and bearing will inevitably lead to the disadvantage of uneven ink color in printing. At the same time, because of skip glue, glide glue
等不良情況引起印刷杠痕。所以，平時應(yīng)勤給膠輥軸頭、軸承加注潤滑油，以防止機件磨損
Bad conditions such as printing bar marks. Therefore, in order to prevent wear and tear of machine parts, it is necessary to inject lubricating oil into the head and bearing of rubber rollers at ordinary times.
膠輥的正常使用，確保印刷質(zhì)量。
The normal use of COTS ensures the printing quality.
4、停機時靠版膠輥與印版滾筒應(yīng)及時脫離接觸卸除負荷，以防靜壓變形。
4. When the machine stops, the relief roll and the plate drum should be separated from each other in time to relieve the load so as to prevent static pressure deformation.
5、在安裝和拆卸時，應(yīng)輕拿輕放，不應(yīng)碰撞輥頸和膠面，以免造成輥體損傷、彎曲或膠面破損；輥頸與軸承配合要嚴密，若松動應(yīng)及時補焊修理。
5. When installing and disassembling, it should be handled lightly and lightly, and the roll neck and rubber surface should not be collided, so as to avoid the damage, bending or rubber surface damage of the roll body; the roll neck should be closely matched with the bearing, and if loose, it should be repaired and repaired in time.
6、印刷結(jié)束后，要把膠輥上的油墨洗干凈。清洗油墨應(yīng)選擇專用的清洗劑，并檢查膠輥上是否還留有紙毛、紙粉沒被洗去，紙毛、紙粉一般停留在勻墨輥上，需拿包布擦拭。
6. After printing, wash the ink on the cots. Cleaning ink should choose a special cleaning agent, and check whether there is still paper wool and powder left on the rubber roll has not been washed, paper wool and powder generally stay on the ink roll, need to wipe with wrapping cloth.
7、在膠輥表面上形成了油墨的硬化膜，即膠面玻璃化時，應(yīng)用浮石粉將其研磨掉。膠輥表面出現(xiàn)龜裂時，盡可能早些將其研磨去掉。
7. A hardening film of ink is formed on the surface of cots, i.e. when the rubber surface is vitrified, pumice powder is used to grind it off. When cracks appear on the surface of cots, grind them off as early as possible.
