Description

兼具冷烫功能的多色印刷机组技术领域 Multi-color printing unit with cold ironing function

本实用新型涉及一种印刷设备，具体涉及一种兼具冷烫功能的多色印刷机组。背景技术 The utility model relates to a printing device, in particular to a multi-color printing unit which has the cold ironing function. Background technique

多色印刷机组主要有多色凹印机组、多色凸印机组、多色胶印机组三种，它们共同的特点是设有多个印刷工位，每个印刷工位负责印刷一种油墨，在每个工位中，都设有压印辊筒、印刷辊筒，工作时，印刷辊筒接触承印物的正面，而压印辊筒接触承印物的背面，由此将印刷辊筒的油墨印到承印物的正面。其中，在凹印机和凸印机中，印刷辊筒为带有印版的辊筒，而在胶印机中，印刷辊筒表面为带有橡皮布的辊筒。上述压印辊筒和印刷辊筒中，压印辊筒是由印刷设备的生产厂商相对固定地安装在机架上的，而印刷辊筒却不是由机械生产厂家固定配套的（因为当印刷图案不同时，凹印机和凸印机需要更换具有不同图案印版，而胶的橡皮也需要更换，所以多色印刷机的印刷辊筒需要由印刷厂商安装上去），也就是说，对于印刷设备的生产厂家而言，只需提供安装印刷辊筒的印刷辊筒支座，不一定需要安装上印刷辊筒。 Multi-color printing units mainly include multi-color gravure printing units, multi-color embossing units, and multi-color offset printing units. Their common feature is that there are multiple printing stations, each printing station is responsible for printing an ink. In each station, there are an embossing roller and a printing roller. When working, the printing roller contacts the front side of the substrate, and the embossing roller contacts the back side of the substrate, thereby printing the ink of the printing roller To the front of the substrate. Among them, in the gravure printing machine and the embossing machine, the printing roller is a roller with a printing plate, and in the offset printing machine, the surface of the printing roller is a roller with a blanket. In the above-mentioned embossing roller and printing roller, the embossing roller is relatively fixedly mounted on the frame by the manufacturer of the printing device, and the printing roller is not fixedly supported by the mechanical manufacturer (because when the printing pattern is not At the same time, the gravure press and the embossing machine need to replace the plates with different patterns, and the rubber of the glue needs to be replaced, so the printing rolls of the multi-color printing machine need to be installed by the printing manufacturer), that is, for the printing equipment. For the manufacturer, it is only necessary to provide a printing roller holder to which the printing roller is mounted, and it is not necessary to install a printing roller.

现有每台机组式多色印刷机只能提供凹印、凸印、胶印三种印刷方式中的一种，而不能实现冷烫功能。所谓冷烫，就是将烫印箔膜的烫印物料层（例如镀铝层）转印到承印物上，使成片的烫印物料层（例如镀铝层）形成一定的图案。烫印箔膜包括金属类烫印箔膜和非金属类烫印箔膜，金属类烫印箔膜例如有真空镀铝冷烫膜或电化金属膜等。 Each of the existing multi-color printing presses can only provide one of three printing methods: gravure, embossing and offset printing, and cannot realize the cold ironing function. The so-called cold ironing is to transfer the hot stamping material layer (for example, the aluminum plating layer) of the hot stamping foil film onto the substrate, so that the sheet of hot stamping material (for example, the aluminum plating layer) forms a certain pattern. The hot stamping foil film comprises a metal stamping foil film and a non-metal stamping foil film, and the metal stamping foil film is, for example, a vacuum aluminum plating cold foil film or an electrochemical metal film.

现有技术中，冷烫工艺需要有专门配置的冷烫设备来实现。冷烫设备包括压印机构、烫印箔膜放卷机构、废膜收卷机构、涂布机构、承印物输出机构、承印物收集机构。压印构设有压印辊筒以及与压印辊筒压合的上压辊。上述冷烫设备的冷烫工艺如下：承印物输出后，机构向前输出承印物，涂布机构在承印物的表面局部涂上粘胶剂 (例如 UV油)，然后，由传纸机构将承印物输送到压印机构，与此同时，烫印箔膜放卷机构也源源不断地将烫印箔膜输送经过压印机构，压印机构将烫印箔膜和承印物压合，承印物上涂有粘胶剂的部位便粘住烫印箔膜的烫印物料层（例如镀铝层），这样，烫印箔膜上一部分位置的烫印物料层便冷烫转印到承印物上涂有粘胶剂的部位，没有涂布粘胶剂的部位则不会沾上烫印物料层，因此烫印物料层会形成预定的图案；而运行经过压印机构的那一部分烫印箔膜由于烫印物料层被粘走，于是就变成为废膜，由废膜收卷机构收集卷走。 In the prior art, the cold ironing process requires a specially configured cold ironing device to be realized. The cold ironing equipment includes an embossing mechanism, a hot stamping foil unwinding mechanism, a waste film winding mechanism, a coating mechanism, a substrate output mechanism, and a substrate collecting mechanism. The embossing is provided with an impression cylinder and an upper pressure roller that is pressed against the impression cylinder. The cold ironing process of the above-mentioned cold ironing equipment is as follows: After the substrate is output, the mechanism outputs the substrate forward, and the coating mechanism partially applies a glue (for example, UV oil) on the surface of the substrate, and then conveys the substrate by the paper passing mechanism. At the same time, the hot stamping foil unwinding mechanism continuously conveys the hot stamping foil film through the embossing mechanism, and the embossing mechanism presses the hot stamping foil film and the substrate, and the substrate is coated with The part of the adhesive sticks to the hot stamping layer of the hot stamping foil film (for example, the aluminum plating layer), so that the hot stamping material layer on a part of the hot stamping foil film is cold-transferred and transferred onto the substrate and coated with the adhesive. The part of the agent, the part not coated with the adhesive will not be stained with the hot stamping material layer, so the hot stamping material layer will form a predetermined pattern; and the part of the hot stamping foil film that runs through the imprinting mechanism is due to the hot stamping material. The layer is stuck away, and then becomes a waste film, which is collected and taken away by the waste film winding mechanism.

由于现有技术中，冷烫设备、多色印刷机组均为各自独立配置的生产设备，印刷厂 ^为了实现冷烫和多色印刷功能，需要同时配置购买两种生产设备，因此投资成本高，占用作业空间大，设备利用率低。实用新型内容 In the prior art, the cold ironing equipment and the multi-color printing unit are independently configured production equipments, and the printing factory needs to simultaneously configure and purchase two kinds of production equipments in order to realize the cold ironing and multi-color printing functions, so the investment cost is high and the occupation is occupied. Large space and low equipment utilization. Utility model content

本实用新型的目的在于克服上述缺点而提供一种兼具冷烫功能的多色印刷机组，它可以节省设备投资成本，减少设备占用作业空间。 The purpose of the utility model is to overcome the above disadvantages and provide a multi-color printing unit which has the cold ironing function, which can save equipment investment cost and reduce equipment occupation work space.

其目的可以按以下方案实现：该兼具冷烫功能的多色印刷机组包括两个以上的印刷工 The purpose can be achieved as follows: The multi-color printing unit with the cold foil function includes more than two printers

A hot stamping foil unwinding mechanism is provided, and a waste film winding mechanism is arranged behind the printing station. A film storage device is arranged behind the hot stamping foil unwinding mechanism, and a waste film storage device is arranged in front of the waste film winding mechanism. In this application, the so-called "front" and "back" are mainly for the order of operation of the substrate or film on the production line. When working, the substrate is also run from the front to the back, and the hot stamping foil is also run from the front to the back. .

本实用新型具有以下优点和效果： The utility model has the following advantages and effects:

1、本实用新型既可以实现冷烫工艺，也可以实现多色印刷工艺。当实现冷烫工艺时，设有烫印箔膜放卷机构、废膜收卷机构的印刷工位可以作为压印工位，即可以利用该工位的印刷辊筒支座安装上一根与压印辊筒压合的辊就可以实现压印，而且可由压印工位前面的一个印刷工位涂布粘胶剂，粘胶剂只需像印刷油墨一样印刷在承印物上面。而当实现多色印刷工艺时，废膜收卷机构、烫印箔膜放卷机构等箔膜控制机构则不参与工作，因此在这种状态下，本实用新型参与工作的部件完全等同于普通的多色印刷机组，多色印刷的工艺、使用方法也完全完全等同于传统的多色印刷工艺、使用方法。 1. The utility model can realize the cold ironing process and the multicolor printing process. When the cold-hot process is implemented, a printing station provided with a hot stamping foil unwinding mechanism and a waste film winding mechanism can be used as an imprinting station, that is, a printing roller support of the working station can be used to mount a press and press. The roller that is pressed by the roller can be embossed, and the adhesive can be applied by a printing station in front of the embossing station, and the adhesive only needs to be printed on the substrate like printing ink. When the multi-color printing process is realized, the foil film control mechanism such as the waste film winding mechanism and the hot stamping foil unwinding mechanism are not involved in the work, and therefore, in this state, the components participating in the work of the present invention are completely equivalent to ordinary ones.

2、本实用新型将冷烫和多色印刷这两种不同的生产设备糅合在一起，并且大部分的机构和零件实现共有，只需增加少量一部分机构和零件，就实现一机两用，所以，与传统技术中分别配置多色印刷机组和冷烫设备的方式比较，本实用新型可以实现节省设备投资成本, 减少设备占用作业空间，提高设备利用率。 2.

具体实施方式 detailed description

实施例一 Embodiment 1

图 1所示，该实施例的兼具冷烫功能的多色印刷机组为多色胶印机组，包括四个印刷工位 1，相邻印刷工位 1之间设有传纸辊筒 13 , 工作时纸张传送方向是从右往左，因此最右边的印刷工位 1是前面第一个印刷工位，依此类推，最左边的印刷工位 1是最后一个印刷工位，在第一个印刷工位前面设有纸张输出机构 2，在最后一个印刷工位后面设有纸张收集机构 3，每个印刷工位设有压印辊筒 11、用于安装印刷辊筒的印刷辊筒支座 12，印刷辊筒支座 12上安装有印刷辊筒 121 (在胶印机中，该印刷辊筒 121又称橡皮辊筒，橡皮辊筒表面可拆卸地包裹有印刷橡皮布）；在第二个印刷工位的前面设有烫印箔膜放卷机构 41 , 该第二个印刷工位的后面设有废膜收卷机构 42。在烫印箔膜放卷机构 41后面设有膜料储放装置 43，在废膜收卷机构 42前面设有废膜储放装置 44。上述膜料储放装置 43和废膜储放装置 44是现有技术，它们在结构上都包括有两根固定导辊和一根活动导辊，当活动导辊水平移动后，绕过两根固定导辊和一根活动导辊的膜料（废膜）的长度会发生增加或缩短，由此实现膜料（废膜）的暂时储存或释放，以适应冷烫间歇性图案的过程中可以节省膜料。上述实施例既可以实现冷烫工艺，也可以实现多色胶印印刷工艺。 As shown in FIG. 1 , the multi-color printing unit of the embodiment having the cold-hot function is a multi-color offset printing unit, comprising four printing stations 1 , and a paper conveying roller 13 is disposed between adjacent printing stations 1 . The paper conveying direction is from right to left, so the rightmost printing station 1 is the first printing station in front, and so on, the leftmost printing station 1 is the last printing station. A paper output mechanism 2 is disposed in front of the first printing station, and a paper collecting mechanism 3 is disposed behind the last printing station. Each printing station is provided with an imprinting roller 11 for printing the printing roller. The roller support 12 is mounted on the printing roller support 12 with a printing roller 121 (in the offset printing machine, the printing roller 121 is also called a rubber roller, and the surface of the rubber roller is detachably wrapped with a printing blanket); A hot stamping foil unwinding mechanism 41 is disposed in front of the second printing station, and a waste film winding mechanism 42 is disposed behind the second printing station. A film storage device 43 is disposed behind the hot stamping foil unwinding mechanism 41, and a waste film storage device 44 is disposed in front of the waste film winding mechanism 42. The above-mentioned film storage device 43 and the waste film storage device 44 are prior art, and both of them structurally include two fixed guide rollers and one movable guide roller, and when the movable guide roller is horizontally moved, two are bypassed. The length of the film (waste film) of the fixed guide roller and one movable guide roller is increased or shortened, thereby realizing temporary storage or release of the film material (waste film), which can be saved in the process of adapting to the cold and intermittent pattern. Membrane. The above embodiment can realize the cold ironing process as well as the multicolor offset printing process.

在进行冷烫工艺之前，可将印刷辊筒 121上印刷橡皮布从印刷辊筒 121上拆卸下来，并将冷烫橡皮布安装在印刷辊筒 121上，使印刷辊筒 121与压印辊筒 1 1压合，形成压印机构，并在烫印箔膜放卷机构 41、压印机构、废膜收卷机构 42之间穿绕上烫印箔膜 6，如图 2所示。在进行冷烫工艺时，纸张输出机构 2输出纸张 5 , 可以由第一个印刷工位 1涂布粘胶剂，涂布粘胶剂的工艺就像印刷油墨一样，接着，将纸张传送到第二个印刷工位，于此同时，烫印箔膜放卷机构 41不断释放出烫印箔膜 6，烫印箔膜 6和纸张 5由第二个印刷工位的压印辊筒 1 1和印刷辊筒 121压合，如图 3所示，这样，烫印箔膜 6上一部分位置的镀铝层便冷烫转印到纸张 5 上涂有粘胶剂的部位，而没有涂布粘胶剂的部位则不会沾上烫印物料层，因此镀铝层会形成预定的图案；然后，运行经过压印机构的那一部分烫印箔膜 6ώ于镀铝层被粘走，于是就变成为废膜，由废膜收卷机构 42收集卷走。如果前后两次冷烫的图案之间有较大间隙，则可以利用膜料储放装置 43和废膜储放装置 44实现膜料在压印点的间歇性运行，以节省烫印箔膜。而纸张在冷烫上镀铝图案后，由后面的传纸辊筒 13逐步传送到纸张收集机构 3进行收集。 Before the cold ironing process, the printing blanket on the printing roller 121 can be detached from the printing roller 121, and the cold stamping blanket is mounted on the printing roller 121, so that the printing roller 121 and the impression roller 1 1 Pressing, forming an embossing mechanism, and winding the hot stamping foil film 6 between the hot stamping foil unwinding mechanism 41, the embossing mechanism, and the waste film winding mechanism 42, as shown in FIG. When the cold ironing process is performed, the paper output mechanism 2 outputs the paper 5, and the adhesive can be applied by the first printing station 1. The process of applying the adhesive is like printing ink, and then, the paper is conveyed to the second. At the same time, the hot stamping foil unwinding mechanism 41 continuously releases the hot stamping foil film 6, the hot stamping foil film 6 and the paper 5 are pressed by the second printing station's stamping roller 1 1 and printing The roller 121 is pressed together, as shown in Fig. 3. Thus, the aluminum-plated layer on a portion of the hot stamping foil film 6 is cold-transferred and transferred to the portion of the paper 5 coated with the adhesive without the application of the adhesive. The part will not be stained with the hot stamping material layer, so the aluminum plating layer will form a predetermined pattern; then, the part of the hot stamping foil film 6 that has passed through the embossing mechanism is stuck to the aluminum plating layer, and then becomes waste. The film is collected and taken away by the waste film winding mechanism 42. If there is a large gap between the two cold-hot patterns before and after, the film material storage device 43 and the waste film storage device 44 can be used to realize the intermittent operation of the film at the embossing point to save the hot stamping foil film. After the paper is plated with aluminum on the cold foil, it is gradually conveyed by the rear transfer roller 13 to the paper collecting mechanism 3 for collection.

当需要进行多色胶印印刷工艺，可将印刷辊筒 121上冷烫橡皮布从印刷辊筒 121 上拆卸下来，并将印刷橡皮布安装在印刷辊筒 121上，使印刷辊筒 121与压印辊筒 1 1压合。并将烫印箔膜 6取走，烫印箔膜放卷机构 41、废膜收卷机构 42、膜料储放装置 43、废膜储放装置 44等箔膜控制机构则不参与工作，因此在这种状态下，参与工作的部件完全等同于普通的多色胶印印刷机组，其工作过程、方法完全等同于现有的多色胶印工艺、方法，第二个印刷工位的工作状态如图 4所示。 When a multi-color offset printing process is required, the cold rubbing blanket on the printing roller 121 can be detached from the printing roller 121, and the printing blanket is mounted on the printing roller 121 to make the printing roller 121 and the printing roller The barrel 1 1 is pressed. The hot stamping foil film 6 is taken away, and the foil film control mechanism such as the hot stamping foil unwinding mechanism 41, the waste film winding mechanism 42, the film storage device 43, and the waste film storage device 44 are not involved in the work, so In this state, the parts involved in the work are completely equivalent to the ordinary multi-color offset printing unit, and the working process and method are completely equivalent to the existing multi-color offset printing process and method. The working state of the second printing station is as shown in the figure. 4 is shown.
