1、新铸制的胶辊不宜马上投入使用
1. The newly cast cots should not be put into use immediately.
由于新铸制的胶辊内部结构还不够稳定，若立即投入使用，容易降低使用寿命。故刚出筒的新胶辊应放置一段时间，使胶辊接触外界环境温湿度后，保持相对的稳定状态，这样可以增加胶体的坚韧性，从而提高耐用效果。
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、闲置胶辊的正确存放
2. Proper storage of idle Cots
待用的胶辊应清洗干净后，用塑料薄膜把胶体封包起来，存放在阴凉、干燥、通风的场所，并呈垂直或水平状态，切不可几根随便堆放在一块或顺手竖靠在墙壁旁，以免使胶体受到不应有的损失，也要避免与酸、碱、油类和尖硬物质等一起存放，以免腐蚀、碰伤胶辊。胶辊保存2——3个月后，应把它改变一下方向，以防长期一个方向放置发生弯曲变形，并注意防止轴头部分生锈。废旧的胶辊在送往加工浇铸的运输过程中，切忌乱扔乱放乱压或重压，保持辊芯不偏芯、不弯曲，以确保辊芯正常利用。
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、胶辊轴头、轴承应保持良好的润滑
3. Good lubrication should be maintained for cot head and bearing.
我们知道，胶辊轴头、轴承的精度直接如何，直接影响到传墨、布墨的效果。若润滑不良引
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
起胶辊轴头，轴承的磨损、间隙，必然导致印刷墨色不均匀的弊病。同时也会因跳胶、滑胶
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
等不良情况引起印刷杠痕。所以，平时应勤给胶辊轴头、轴承加注润滑油，以防止机件磨损
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.
胶辊的正常使用，确保印刷质量。
The normal use of COTS ensures the printing quality.
4、停机时靠版胶辊与印版滚筒应及时脱离接触卸除负荷，以防静压变形。
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、在安装和拆卸时，应轻拿轻放，不应碰撞辊颈和胶面，以免造成辊体损伤、弯曲或胶面破损；辊颈与轴承配合要严密，若松动应及时补焊修理。
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、印刷结束后，要把胶辊上的油墨洗干净。清洗油墨应选择专用的清洗剂，并检查胶辊上是否还留有纸毛、纸粉没被洗去，纸毛、纸粉一般停留在匀墨辊上，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、在胶辊表面上形成了油墨的硬化膜，即胶面玻璃化时，应用浮石粉将其研磨掉。胶辊表面出现龟裂时，尽可能早些将其研磨去掉。
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.
