一般来说，克重低、质料等级低的纸板，在冬季的可能性较大。但是现在很多
蔬菜包装厂家都是用等级比较高的纸板，如果还有爆线的话，那我们就要考虑茄子包装纸箱压线的问题了。
Generally speaking, the paperboard with low weight and material grade is more likely in winter. But now many vegetable packaging manufacturers use high-grade cardboard. If there is still a burst line, then we need to consider the problem of eggplant packaging carton line pressing.
印刷的制版分为印前制版和正式制版，制版轮主要起压碎瓦楞纸的作用，压碎瓦楞纸后，使其塌陷，有利于纸箱成型。通过对压路机的正确调整和设备的改进，可以减少爆线的发生。
The printing plate making is divided into pre press plate making and formal plate making. The plate making wheel is mainly used to crush the corrugated paper. After crushing the corrugated paper, it collapses, which is conducive to the formation of cartons. Through the correct adjustment of the roller and the improvement of the equipment, the occurrence of line burst can be reduced.
不同类型的压力管道:
Different types of penstocks:
1. 线辊设计不合理
1. Unreasonable design of wire roller
工厂一般配备两套压力管路轮，一套冬季使用压力管路和预压轮。
The factory is generally equipped with two sets of pressure pipeline wheels, one set of pressure pipeline and preloading wheel in winter.
2.预压轮与压线轮间隙值调整不当
2. The gap between preloading wheel and crimping wheel is not adjusted properly调整压力管路轮时，应检查预压轮间隙是否合理。许多操作人员在调整两个压力轮时没有正确调整间隙值。如果一个特定的纸板厚度是6毫米,印前车轮间隙调整5毫米,然后是压力线轮间隙调整2毫米,所以压力线破裂概率高,或印前车轮间隙调整到2毫米,压力线是2毫米,这盒成型成圆角,丑陋的外表。
When adjusting the pressure pipeline wheel, check whether the clearance of the preloading wheel is reasonable. Many operators did not adjust the clearance value correctly when adjusting the two pressure wheels. If a specific cardboard thickness is 6 mm, the pre press wheel gap is adjusted by 5 mm, then the pressure line wheel gap is adjusted by 2 mm, so the probability of pressure line rupture is high, or the pre press wheel gap is adjusted to 2 mm, and the pressure line is 2 mm, this box is shaped into a round corner, ugly outer surface.
3.设备的实际价值被忽略
3. The actual value of the equipment is ignored操作员将根据数据显示或索引数据进行调整，并忽略设备的实际值。在设备的长期使用中，gap的数据值会有一些差异。同时，设备的平行度也会导致印刷机的调整数据不准确。因此，保持压印线与印前数据之间的并行性关重要。
The operator will adjust according to the data display or index data and ignore the actual value of the equipment. In the long-term use of equipment, gap data value will have some differences. At the same time, the parallelism of the equipment will also lead to inaccurate adjustment data of the printing press. Therefore, it is very important to keep the parallelism between imprinting line and prepress data.
4.预压轮的修改
4. Modification of preloading wheel
1)有些三级厂链机没有预压轮，那么可以考虑用预压轮代替纸轮进行预压。有了预印轮，还可以把一组纸轮换成预印轮，这样纸板经过两次预印线爆裂的概率就会大大降低。
1) Some three-stage chain machines do not have preloading wheel, so it can be considered to use preloading wheel instead of paper wheel for preloading. With a prepress wheel, you can also change a group of paper wheels into prepress wheels, so that the probability of cardboard bursting after two prepress lines will be greatly reduced.
2)改进了预压轮。传统印刷机的印前轮是由不同弧度的铁制成的。预印轮的弧度较大，纸箱成型容易形成圆角，不及预印效果，从而容易导致纸板生产线爆裂。
2) The preloading wheel is improved. The front printing wheel of traditional press is made of iron with different radians. The camber of the prepress wheel is large, and the paper box is easy to form a round corner, which is not as good as the prepress effect, so it is easy to cause the bursting of the paperboard production line.
改进方法:预印轮的上轮采用牛筋胶或友利胶等弹性材料制成，友利胶面应具有弧度槽，起到缓冲作用，使纸板不易爆裂;下轮采用压线轮，进行预印。这样，预印就可以提前实现对线点、纸箱成型效果的控制。
Improvement method: the upper wheel of the prepress wheel is made of elastic materials such as gluten rubber or friendly rubber, and the friendly rubber surface should have an arc groove to play a buffer role, so that the cardboard is not easy to burst; the lower wheel uses the line pressing wheel for prepress. In this way, pre printing can realize the control of line point and carton forming effect in advance.
5.线辊变形
5. Deformation of wire roller
对压轮的宽度和深度进行合理的计算，然后将压轮做大，使压轮的脉动减小，有利于压箱。
Firstly, the width and depth of the roller are calculated reasonably, and then the roller is enlarged to reduce the pulsation of the roller, which is beneficial to the box.
6.人员操作改进压力线
6. Pressure line for personnel operation improvement1)选择两个预加载时，逐渐减小预加载间隙，由大到小排序，检查预加载位置是否正确。
1) When selecting two preloads, gradually reduce the preload gap, sort from large to small, and check whether the preload position is correct.
2)线辊之间的间隙要逐渐增大，一般以不爆裂为基准。
2) The gap between the line rollers should be gradually increased, generally based on non bursting.
3)生产过程中定期检查压力线深度，检查压力线轮的圆度和平衡点。
3) In the production process, the depth of the pressure line shall be checked regularly, and the roundness and balance point of the pressure line wheel shall be checked.
4)如果订单比较急，没有时间使硬纸板水分平衡，温水直接送到硬纸板表面即可。潮湿时不要影响印刷面积，否则会对印刷造成不良影响。如果条件允许，可以用废场板做一个湿水板，先用湿水排上一个印刷工位，再进行印刷。这样，在不影响印刷质量的情况下，湿水可以被应用到压线上。
4) If the order is urgent, there is no time to make the cardboard water balance, warm water can be sent directly to the surface of the cardboard. Do not affect the printing area when it is wet, otherwise it will cause adverse effects on printing. If conditions permit, a wet water plate can be made from waste field plate, and wet water can be drained to a printing station before printing. In this way, the wet water can be applied to the pressing line without affecting the printing quality.
5)在某些客户边压强度和抗压强度要求不高,可用于印刷机印刷增加纸的压力或压力,茄子包装纸箱纸板瓦楞压扁,适当缓冲反弹,瓦楞纸板会变干软适当的压力,但它可以大大减少纸箱抗压强度(通常不这个解决方案)。
5) In some customers, the side pressing strength and compressive strength requirements are not high, which can be used for printing machine to increase the pressure or pressure of paper, eggplant packaging carton cardboard corrugating flattening, appropriate buffer rebound, corrugating cardboard will become dry and soft, but it can greatly reduce the compressive strength of cartons (usually this solution is not recommended).
