Description

瓦楞纸板生产线温度控制***Corrugated cardboard production line temperature control system 技术领域Technical field
本申请涉及瓦楞纸生产***技术领域，具体的说是一种瓦楞纸板生产线温度控制***。The present application relates to the technical field of corrugated paper production systems, in particular to a temperature control system for a corrugated paperboard production line.
背景技术Background technique
由于各种原因，包括天气变化造成现场环境和原纸的温度湿度变化、客户订单批量小品种多造成原纸规格门幅转换频繁、原纸规格、结构、物理性能的差异、粘合剂性能的差异、生产线的机速变化、操作人员经验技术参差不齐等都会造成瓦楞纸板生产线生产时品质不稳定或效率低下。行业中为了解决这些问题，提供了一些控制***，其中所有的瓦楞纸板生产线湿段单面瓦楞纸板以及纸板生产时，配置有一些温度控制***或手动模式来控制原纸预热缸或预热预调器的包角角度，以使瓦纸、芯纸、里纸、或面纸吸收不同程度热量，然后进行涂胶和粘合。Due to various reasons, including changes in the on-site environment and the temperature and humidity of the base paper due to weather changes, frequent changes in the width of the base paper specifications due to the small variety of customer orders, differences in base paper specifications, structure, physical properties, differences in adhesive properties, production lines Changes in machine speed, and uneven experience and technical skills of operators will cause unstable or inefficient production of corrugated cardboard production lines. In order to solve these problems in the industry, some control systems are provided. All corrugated cardboard production lines are equipped with some temperature control systems or manual modes to control the base paper preheating cylinder or preheating pre-adjustment during the production of single-sided corrugated paperboard and paperboard in the wet section. The angle of the wrapper of the device allows the tile paper, core paper, liner paper, or face paper to absorb different degrees of heat, and then glue and glue.
目前的瓦楞纸板生产线除手动模式外，一般采用两种控制模式，一种是根据机速自动调整包角角度，另一种是根据原纸通过预热缸或预热预调器预热之后的表面温度自动调整包角角度。上述这些控制***虽然能在某种程度上提高一些车速或提升一些单面瓦楞纸板品质，但由于影响原纸加温的综合因素较多，上述这些***均无法相对准确地控制着瓦纸、芯纸、里纸或面纸粘合时所需的表面温度，因此还是会经常造成单面瓦楞纸板及纸板质量不稳定，浪费损耗大，以及效率不理想的情况发生，尤其是大部分操作人员为了保证单面瓦楞纸板以及纸板粘合不开胶，一般都会加大预热缸、预热预调器的包角角度或提高蒸汽 压力，加大粘合剂的涂胶量，这样就会让原纸过度加热，超过所需的粘合温度和粘合剂用量，原纸物理性能遭到不同程度破坏，最终造成单面瓦楞纸板以及纸板的各项强度包括边压和耐破强度的劣化，另一方面也造成能源与粘合剂的极大浪费。In addition to the manual mode, the current corrugated board production line generally uses two control modes, one is to automatically adjust the wrap angle according to the machine speed, and the other is the surface after the base paper is preheated by the preheating cylinder or preheater The temperature automatically adjusts the wrap angle. Although the above-mentioned control systems can improve the speed of some vehicles or the quality of some single-sided corrugated cardboard to some extent, due to the comprehensive factors affecting the heating of the base paper, these systems cannot control the paper and core paper relatively accurately. The surface temperature required for the bonding of paper, liner or face paper, so the quality of single-sided corrugated paperboard and paperboard is often unstable, wasteful and lossy, and the efficiency is not ideal, especially for most operators to ensure Single-sided corrugated cardboard and cardboard are not glued. Generally, the angle of the preheating cylinder and preheater is increased, or the steam pressure is increased. The amount of adhesive applied is increased, which will overheat the base paper. , Exceeds the required bonding temperature and the amount of adhesive, the physical properties of the base paper are damaged to varying degrees, eventually causing the deterioration of the strength of the single-sided corrugated board and paperboard, including side pressure and burst strength, on the other hand, it also causes Great waste of energy and adhesives.
