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.

　　印刷的制版分為印前制版和正式制版，制版輪主要起壓碎瓦楞紙的作用，壓碎瓦楞紙后，使其塌陷，有利于紙箱成型。通過對壓路機的正確調整和設備的改進，可以減少爆線的發生。

　　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.

　　不同類型的壓力管道:

　　Different types of penstocks:

　　1. 線輥設計不合理

　　1. Unreasonable design of wire roller

　　工廠一般配備兩套壓力管路輪，一套冬季使用壓力管路和預壓輪。

　　The factory is generally equipped with two sets of pressure pipeline wheels, one set of pressure pipeline and preloading wheel in winter.

　　2.預壓輪與壓線輪間隙值調整不當

　　2. The gap between preloading wheel and crimping wheel is not adjusted properly調整壓力管路輪時，應檢查預壓輪間隙是否合理。許多操作人員在調整兩個壓力輪時沒有正確調整間隙值。如果一個特定的紙板厚度是6毫米,印前車輪間隙調整5毫米,然后是壓力線輪間隙調整2毫米,所以壓力線破裂概率高,或印前車輪間隙調整到2毫米,壓力線是2毫米,這盒成型成圓角,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.設備的實際價值被忽略

　　3. The actual value of the equipment is ignored操作員將根據數據顯示或索引數據進行調整，并忽略設備的實際值。在設備的長期使用中，gap的數據值會有一些差異。同時，設備的平行度也會導致印刷機的調整數據不準確。因此，保持壓印線與印前數據之間的并行性關重要。

　　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.預壓輪的修改

　　4. Modification of preloading wheel

　　1)有些三級廠鏈機沒有預壓輪，那么可以考慮用預壓輪代替紙輪進行預壓。有了預印輪，還可以把一組紙輪換成預印輪，這樣紙板經過兩次預印線爆裂的概率就會大大降低。

　　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)改進了預壓輪。傳統印刷機的印前輪是由不同弧度的鐵制成的。預印輪的弧度較大，紙箱成型容易形成圓角，不及預印效果，從而容易導致紙板生產線爆裂。

　　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.

　　改進方法:預印輪的上輪采用牛筋膠或友利膠等彈性材料制成，友利膠面應具有弧度槽，起到緩沖作用，使紙板不易爆裂;下輪采用壓線輪，進行預印。這樣，預印就可以提前實現對線點、紙箱成型效果的控制。

　　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.線輥變形

　　5. Deformation of wire roller

　　對壓輪的寬度和深度進行合理的計算，然后將壓輪做大，使壓輪的脈動減小，有利于壓箱。

　　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.人員操作改進壓力線

　　6. Pressure line for personnel operation improvement1)選擇兩個預加載時，逐漸減小預加載間隙，由大到小排序，檢查預加載位置是否正確。

　　1) When selecting two preloads, gradually reduce the preload gap, sort from large to small, and check whether the preload position is correct.

　　2)線輥之間的間隙要逐漸增大，一般以不爆裂為基準。

　　2) The gap between the line rollers should be gradually increased, generally based on non bursting.

　　3)生產過程中定期檢查壓力線深度，檢查壓力線輪的圓度和平衡點。

　　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)如果訂單比較急，沒有時間使硬紙板水分平衡，溫水直接送到硬紙板表面即可。潮濕時不要影響印刷面積，否則會對印刷造成不良影響。如果條件允許，可以用廢場板做一個濕水板，先用濕水排上一個印刷工位，再進行印刷。這樣，在不影響印刷質量的情況下，濕水可以被應用到壓線上。

　　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)在某些客戶邊壓強度和抗壓強度要求不高,可用于印刷機印刷增加紙的壓力或壓力,茄子包裝紙箱紙板瓦楞壓扁,適當緩沖反彈,瓦楞紙板會變干軟適當的壓力,但它可以大大減少紙箱抗壓強度(通常不這個解決方案)。

　　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).
