（5）加热压合：单元化蜂窝废料颗粒喷洒过胶液后被输送至压合装置，进行压合，温度设置为70℃，压力为70Pa，压合成具有一定蓬松度、厚度为30mm的蜂窝废料板坯。(5) Heating and pressing: After the unitized honeycomb waste particles are sprayed with glue, they are transported to the pressing device for pressing. The temperature is set to 70°C, the pressure is 70Pa, and the honeycomb with a certain bulkiness and a thickness of 30mm is pressed into a honeycomb. Scrap slabs.
（6）干燥与后处理：蜂窝板坯在60-70℃下进行烘干，然后用模切机进行模切，得到尺寸为底面积为10mm*10mm的长方体填充块，用作被包装物与包装箱之间的填充物，起到固定产品、保护产品的作用。(6) Drying and post-processing: The honeycomb slabs are dried at 60-70 °C, and then die-cut with a die-cutting machine to obtain a cuboid filling block with a bottom area of 10mm*10mm, which is used as a packaged material and The filler between the boxes plays the role of fixing the product and protecting the product.
实施例2：一种在蜂窝废料含水率较高时的处理工艺，包括以下步骤：Embodiment 2: a processing technique when the honeycomb waste has a high moisture content, comprising the following steps:
（1）废料收集与输送：收集蜂窝废料，将其在30℃烘干机内烘2min，然后用输送装置进行输送。(1) Waste collection and transportation: Collect honeycomb waste, dry it in a dryer at 30°C for 2 minutes, and then transport it with a conveying device.
（2）废料分切：将收集来的纸蜂窝废料在分切装置中分切成尺寸为30mm*30mm*30mm的蜂窝纸板废料。(2) Waste slitting: The collected paper honeycomb waste is cut into honeycomb cardboard waste with a size of 30mm*30mm*30mm in the slitting device.
（3）分切废料空抛与喷胶：将单元化物料进行抛洒，抛洒的同时喷洒胶液。抛洒管道四周有定点8个，喷头在持续喷洒粉状胶液，胶液为热熔胶。根据热熔胶熔点为60℃-80℃，环境加温至80℃。(3) Slitting waste empty throw and glue spray: throw the unitized material, and spray glue at the same time. There are 8 fixed points around the throwing pipe, and the nozzle is continuously spraying powdered glue, and the glue is hot melt glue. According to the melting point of the hot melt adhesive, it is 60°C-80°C, and the environment is heated to 80°C.
（4）分切废料定厚推送：喷胶后的蜂窝废料自然地落在输送装置上，并随输送装置上向前推送。本实施方式选取的厚度为80mm。输送装置另一头有厚度调节器，高出既定80mm的物料被厚度调节器反向拨到推送一头，保证下一环节板坯的初始厚度为80mm。(4) Slitting and pushing the waste with a fixed thickness: the honeycomb waste after spraying glue naturally falls on the conveying device, and is pushed forward with the conveying device. The thickness selected in this embodiment is 80 mm. There is a thickness adjuster at the other end of the conveying device, and the material higher than the predetermined 80mm is reversed to the push end by the thickness adjuster to ensure that the initial thickness of the slab in the next link is 80mm.
（5）加热压合：单元化结构蜂窝废料喷洒过胶液后被输送至压合装置，进行压合，温度设置为90℃，压力为90Pa，压合成具有一定蓬松度、厚度为30mm的蜂窝废料板坯。(5) Heating and pressing: After the unitized honeycomb waste is sprayed with glue, it is transported to the pressing device for pressing. The temperature is set to 90°C and the pressure is 90Pa, and it is pressed into a honeycomb with a certain bulkiness and a thickness of 30mm. Scrap slabs.
（6）干燥与后处理：蜂窝板坯在60-70℃下进行烘干，然后用涂胶贴覆瓦楞纸板，增强表面平整性与整体性。(6) Drying and post-treatment: The honeycomb slab is dried at 60-70 ℃, and then glued to the corrugated cardboard to enhance the surface smoothness and integrity.
本发明采用的工艺流程高效简单，整个过程不产生有害物，并且成品可回收、可降解、再利用，大大提高了纸蜂窝废料再生利用的经济性。本发明加工中在胶液内加入一定的防潮剂、阻燃剂、填充料，从而使加工出的产品兼具强度高、防静电、环保、抗压等优良性能，符合各类产品的缓冲包装要求。采用此工艺配方，可以针对包装产品重量、大小、防护级数等，采用单面或双面的自由复合、模切成不同大小，既可作衬垫型缓冲包装材料，又可作填充料型缓冲包装材料，使产品的适用范围得到有效的扩大。The technological process adopted by the present invention is efficient and simple, no harmful substances are produced in the whole process, and the finished product can be recovered, degraded and reused, which greatly improves the economy of recycling paper honeycomb waste. In the process of the invention, certain moisture-proof agents, flame retardants and fillers are added into the glue solution, so that the processed products have excellent properties such as high strength, anti-static, environmental protection, and compression resistance, which are in line with the buffer packaging of various products. Require. With this process formula, one-sided or double-sided free lamination and die-cut to different sizes can be adopted according to the weight, size, protection level, etc. of the packaged product, which can be used as both a cushioning type cushioning packaging material and a filling material type. Buffer packaging materials, so that the scope of application of the product has been effectively expanded.
