(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)線輥不合理。在紙板壓制線上使用較多的是凸面到凹面。由于使用紙張、生產環境、紙板厚度不同，所使用的線輥的結構也不同。主要參數是上下壓線輪的寬度要合適，以及壓線輪的臺階過渡圓弧要根據壓線的深度和適用的蔬菜紙箱板來調整。紙板越厚，線的寬度應該越大，對于三層紙板也可以采用圓弧壓線輪。壓路機的結構不統一，需要操作者根據實際情況，找出合適的壓路機結構。

　　(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.

　　解決方案

　　Solution

　　(1)改進線輪結構。為了調整線輪的結構，可以適當增大線輪的臺階過渡圓弧半徑。

　　(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)采取預壓損傷的方式，預壓前正式壓線。它的缺點是壓力管道的形成。

　　(2) Take the way of preloading damage, and formally press the line before preloading. Its disadvantage is the formation of pressure pipeline.

　　(3)對原紙的質量要求較好，對于要求較高的紙板應是質量較好的表面紙和紙張。

　　(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)原紙和紙板的含水率應適宜。原紙質量越低，紙板越干燥，壓紙線斷裂的概率越高。

　　(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)正確控制壓力管道的深度。根據加工后紙板的厚度來控制上下壓路機之間的間隙，使紙板能得到適當的壓線。

　　(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、下壓力線輪線對中，防止壓力線輪對中。

　　(6) Center line alignment of upper and lower pressure line wheels shall be controlled to prevent pressure line wheel alignment.

　　(7)原紙質量較差的紙板，用撞線器碰觸紙板。

　　(7) For the paperboard with poor quality of base paper, touch the paperboard with the thread collider.

　　(8)若因蔬菜紙箱板干燥造成壓線斷裂，可采用噴水方式增加紙板含水量。

　　(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.
