(1)垂线轧制压力过高。当纸板进入压线轮运行时，压线轮压碎纸板，造成纸板在纸或面纸上按瓦楞方向断裂。为了解决这一问题，有必要根据纸板的厚度来调整垂直压线轮的压力。一般情况下，蔬菜包装厂家三层纸板的压线深度足以将压线轮压入2mm3mm的纸板内。但在正常生产中，操作人员应根据原纸的质量来调整压力，以不压碎易折叠为标准。
(1) The vertical rolling pressure is too high. When the paperboard enters the line pressing wheel, the line pressing wheel will crush the paperboard, causing the paperboard to break in the direction of corrugating on the paper or face paper. In order to solve this problem, it is necessary to adjust the pressure of the vertical pressing wheel according to the thickness of the paperboard. In general, the pressing depth of the three-layer cardboard of vegetable packaging factory is enough to press the pressing wheel into the cardboard of 2mm-3mm. But in the normal production, the operator should adjust the pressure according to the quality of the base paper, with the standard of no crushing and easy folding.
(2)线辊不合理。在纸板压制线上使用较多的是凸面到凹面。由于使用纸张、生产环境、纸板厚度不同，所使用的线辊的结构也不同。主要参数是上下压线轮的宽度要合适，以及压线轮的台阶过渡圆弧要根据压线的深度和适用的蔬菜纸箱板来调整。纸板越厚，线的宽度应该越大，对于三层纸板也可以采用圆弧压线轮。压路机的结构不统一，需要操作者根据实际情况，找出合适的压路机结构。
(2) The line roller is unreasonable. In the paperboard pressing line, convex to concave is often used. Due to the use of paper, production environment, cardboard thickness, the structure of the line roller used is also different. The main parameters are that the width of the upper and lower line pressing wheels should be appropriate, and the transition arc of the step of the line pressing wheel should be adjusted according to the depth of the line pressing and the applicable vegetable carton board. The thicker the paperboard is, the wider the line should be. For three-layer paperboard, the arc pressing wheel can also be used. The roller structure is not uniform, so the operator needs to find out the appropriate roller structure according to the actual situation.
解决方案
Solution
(1)改进线轮结构。为了调整线轮的结构，可以适当增大线轮的台阶过渡圆弧半径。
(1) Improve the structure of wire wheel. In order to adjust the structure of the wire wheel, the radius of the step transition arc of the wire wheel can be increased appropriately.
(2)采取预压损伤的方式，预压前正式压线。它的缺点是压力管道的形成。
(2) Take the way of preloading damage, and formally press the line before preloading. Its disadvantage is the formation of pressure pipeline.
(3)对原纸的质量要求较好，对于要求较高的纸板应是质量较好的表面纸和纸张。
(3) The quality of the base paper is better, and the paperboard with higher requirements should be the surface paper and paper with better quality.
(4)原纸和纸板的含水率应适宜。原纸质量越低，纸板越干燥，压纸线断裂的概率越高。
(4) The moisture content of base paper and paperboard shall be suitable. The lower the quality of the base paper and the drier the paperboard, the higher the probability of the paper line breaking.
(5)正确控制压力管道的深度。根据加工后纸板的厚度来控制上下压路机之间的间隙，使纸板能得到适当的压线。
(5) Control the depth of pressure pipe correctly. According to the thickness of the processed paperboard, the gap between the upper and lower rollers is controlled so that the paperboard can be properly pressed.
(6)控制上、下压力线轮线对中，防止压力线轮对中。
(6) Center line alignment of upper and lower pressure line wheels shall be controlled to prevent pressure line wheel alignment.
(7)原纸质量较差的纸板，用撞线器碰触纸板。
(7) For the paperboard with poor quality of base paper, touch the paperboard with the thread collider.
(8)若因蔬菜纸箱板干燥造成压线断裂，可采用喷水方式增加纸板含水量。
(8) If the pressing line is broken due to the drying of the vegetable carton board, the water content of the board can be increased by spraying water.
