瓦楞纸箱模切技术及实用知识

1.1、平压平模切
1.1 flat pressing and die cutting
平压平模切采用平板刀模和平口的模切刀,在模切时刀片同时切穿整张瓦楞纸板,模切精度,使用面较广,不干胶、卡纸、瓦楞纸板等材料都可以适用。
The flat die-cutting adopts a flat die-cutting knife with flat die and flat mouth. During die-cutting, the blade cuts through the whole corrugated board at the same time. The die-cutting precision is the highest and the application range is wide. The self-adhesive, cardboard, corrugated board and other materials can be applied.
平压平模切机有立式半自动模切机和卧式自动模切机之分,立式模切设备结构简单、维修方便、易于操作和更换模切压痕版,但该工艺劳动强度较大,生产效率低,每分钟工作次数多为20次~30次,常用于小批量生产加工。
The flat die cutting machine can be divided into vertical semi-automatic die cutting machine and horizontal automatic die cutting machine. The vertical die cutting equipment has the advantages of simple structure, convenient maintenance, easy operation and replacement of die-cutting indentation plate, but the process has high labor intensity and low production efficiency. The working times per minute are mostly 20 ~ 30 times, which is commonly used in small batch production and processing.
卧式平压平模压机总体结构与单张纸胶印机类似,整机由纸板自动输入系统、模压部分、纸板输出部分以及电气控制、机械传动等部分组成,有的还带有自动清废装置,工作安全可靠,自动化程度、生产效率高。
The overall structure of the horizontal flat die press is similar to that of the sheet fed offset press. The whole machine is composed of paperboard automatic input system, molding part, paperboard output part, electrical control, mechanical transmission and other parts. Some are also equipped with automatic waste removal devices, which are safe and reliable, with high automation and production efficiency.
1.2、圆压平模切
1.2 circular flattening die cutting
采用了圆筒形的压力滚筒代替压板,一般压切辊在上,模切版在下,模切时以“线接触”方式进行加工,使机器在模压时所承受的压力较小,而且分布均匀,因而机器的负载比较平稳,可进行较大幅面的模切,该方式适合多种材质厚度不同的产品模切。但一般圆压平模切均是停回转或一回转、两回转为一个工作循环,因此效率低,目前使用较少。

A cylindrical pressure roller is used to replace the pressing plate. Generally, the pressure cutting roller is on the top and the die cutting plate is on the bottom. During die cutting, the machine is processed in the way of "line contact", so that the pressure borne by the machine during die pressing is small and evenly distributed. Therefore, the load of the machine is relatively stable and can be used for die cutting of large format. This method is suitable for die cutting of products with different material thickness. However, the general circular flattening die-cutting is to stop rotating or one or two rotating into a working cycle, so the efficiency is low and it is rarely used at present.
1.3、圆压圆模切
1.3 circular die cutting
圆压圆型模切机进入我国已有20多年历史,其模压滚筒连续旋转,因而其生产效率是各类模压机中的,产品模切精度高,可控制在±1毫米,同时具有设备操作简单、安全可靠、设备使用时间长等优点。就目前瓦楞纸箱印后加工的模切设备来说,圆压圆模切已经成为主流。
The circular die-cutting machine has entered China for more than 20 years. Its molding drum rotates continuously, so its production efficiency is the highest among all kinds of molding machines. The product die-cutting precision is high, which can be controlled within ± 1mm. At the same time, it has the advantages of simple equipment operation, safety and reliability, long equipment service time and so on. At present, for the die-cutting equipment for post press processing of corrugated boxes, circular die-cutting has become the mainstream.
其模压版采用弧形木板、滚筒刀制作,对模切刀的强度要求较高,刀模的制作难度及成本大,适合批量较大的生产加工。圆压圆的模切方式,一般分为硬切法和软切法两种。主要区别在于压切滚筒的材质一种是硬质的钢辊,一种为软质的塑胶。
The die plate is made of arc-shaped wood board and roller knife, which has high requirements for the strength of die-cutting knife, and the manufacturing difficulty and cost of knife die are large. It is suitable for mass production and processing. The die-cutting method of circular pressing is generally divided into hard cutting method and soft cutting method. The main difference is that the material of the press cutting roller is hard steel roller and soft plastic roller.
硬切法是指模切时模切刀与压力滚筒表面硬性接触,因而模切刀较容易磨损、卷刃。软切法是在压切滚筒的表面覆盖一层工程塑料,模切时,切刀可有一定的切入量,这样既可保扩切刀,又能保证完全切断,但需定期更换塑料层,否则会因为线速度不一致导致模切尺寸不准确。
Hard cutting method refers to the hard contact between the die-cutting knife and the surface of the pressure drum during die-cutting, so the die-cutting knife is easy to wear and roll. The soft cutting method is to cover the surface of the pressure cutting drum with a layer of engineering plastic. During die cutting, the cutter can have a certain cutting amount, which can not only ensure the expansion of the cutter, but also ensure complete cutting. However, the plastic layer needs to be replaced regularly, otherwise the die cutting size will be inaccurate due to inconsistent linear speed.
