Depth analysis: production process of egg tray / box pulp molding equipment


 在批发鸡蛋市场农贸市场上,我们通常可以看到不起眼的鸡蛋托盘或鸡蛋盒包装,里面装有整洁而精致的鸡蛋产品,成千上万个鸡蛋相互堆叠。并用卡车运输到全国各地。它似乎是一个简单的包装,但其生产过程比我们想象的要难得多。


 鸡蛋托盘的生产过程通常包括四个部分:制浆,成型,干燥和包装。鸡蛋纸盒制造机是由鸡蛋托盘设备改造的新型纸浆成型线。生产过程涵盖了生产过程。纸制鸡蛋托机的生产过程,所以鸡蛋托干燥后,应增加鸡蛋托的生产过程,然后进行包装。下面,让我们讨论鸡蛋纸箱的处理流程。

 1.制浆系统

 The pulping system is the first step in the pulp molding process and is an important part of the entire paper industry, with the aim of making waste paper into pulp. Usually, in the process flow, the raw materials of the egg tray and egg box (such as used newspapers, books, office waste paper, etc.) are first placed in a hydraulic pulper to be stirred and pulverized. At this time, there are more impurities in the pulp, so it is necessary A smoother, more uniform pulp can be obtained by impurity separation, screening, sand removal and spalling. In order to give the product special functions (such as waterproof, moisture-proof, anti-static, etc.), it is necessary to add a small amount of functional additives to the slurry tank for slurrying, and add water and white water for production. Because pulp is used in various production processes, the purity of the pulp directly affects the damage of the equipment, so a powerful pulping system is very important for the entire process.


 At the same time, in addition to these machines, it is necessary to build some pools. The number of pools is related to the size of the production line, especially the amount of pulp required for production.


 2.Molding system

 The molding system is the second and core part of the pulp molding production process. The system mainly includes vacuum pumps, air compressors, pulp molding machines and cleaning equipment. Among them, the pulp molding machine is the key equipment of the molding system, and it is also the direct cause of the different manufacturing processes of the egg tray and the egg carton. In addition, the vacuum pump helps to shape, while the air compressor is used to remove the wet product from the mold. After the wet embryo is demolded, the cleaning equipment is quickly and neatly rinsed to maintain the mold-to-machine and ensure the quality of each final product. average. The equipment process needs to be carried out in an orderly and precise manner, so as to ensure the continuity of production.


 3.Drying system

 After the wet embryo is demolded, it needs to be dried. Among them, in the history of drying process, there are a variety of drying modes to choose from. Environmentally friendly and energy-saving natural drying methods (ie drying, drying or drying in the sun) are usually not selected by the public because of their low drying efficiency, so manufacturers are more inclined to choose efficient drying processes within the range of production costs. That is, using coal, fuel oil and gas as fuel, the heat is transferred to the inside of the drying line through a heat medium such as steam or heat transfer oil, thereby drying the egg box wet embryo and passing it to the next process.


 4.Packaging system

 Different products require different packaging equipment. The packaging equipment commonly used for egg box (paper) products is a packaging machine, a counter and a hot press. At the same time, the packaging system is also a different process between the egg tray process and the egg box process. Because the unit price of the egg box is usually slightly higher than the cost of the egg tray, the egg box product requires a better appearance and quality, so before the egg box is packaged, we usually set the hot press before the packing process and the egg. The box product is reshaped to obtain a higher quality egg box.

 最后,使用纸浆成型设备的蛋托机可回收废物并减少污染。大家都知道,大多数的鸡蛋托盘都是由废纸制成的,并且鸡蛋托盘机器将这些肥料整合在一起。蛋托的形成符合现代人的生活观念,既减少了资源浪费,又保护了环境。在当今社会,鸡蛋食品已成为日常生活中必不可少的对象,鸡蛋的销售量越来越大,这也推动了副工业产品(例如蛋托)的使用。交付鸡蛋后,鸡蛋托盘不得少于一个。蛋托制造业的销售也将越来越大。
