Problems solved by technology

[0005] For the above methods, specifically for lottery printing, due to its special material settings and the existence of multiple scratch-off layers and display layers, even if the printed matter is flat enough, sometimes there will be tension problems, so it is urgent to provide a system. So that the tension control problem in printing die-cutting can be solved, and further, the realization scheme should be automatic without manual participation

Embodiment 1

[0028] like figure 1 As shown in the figure, the first embodiment of the present application provides an automatic control system for printing die-cutting tension. According to the conveying direction of the substrate, a printing module 110, a tension detection module 120, a controller 130, a tension adjustment module 140, and a pressure line cross-cutting module are arranged in sequence. 150, the substrates are conveyed by the synchronous belt between the modules.

[0029] The printing module 110 is connected with the controller 130, and the printing operation is completed according to the instructions of the controller 130. Further printing modules can also integrate the substrate conveying chassis, the substrate conveying drive roller, the substrate conveying driven roller and the substrate inclination correction roller. , There are substrate conveying guide plates on both sides of the driving roller and the driven roller, and the two guide plates are arranged opposite each...

Embodiment 2

[0040] The second embodiment of the present application provides an automatic control method for printing die-cutting tension, such as figure 2 shown, including:

[0041] Step 210: In response to the image printing request, adjust the printing parameters according to the bitmap of the image; including the following sub-steps:

[0042] Step 2101, splitting a plurality of bitmaps from the image;

[0043] The image is composed of multiple regions, and each region includes information such as region color, transparency, and position. Each region constitutes a bitmap, and the bitmap includes color information, transparency information, and position information.

[0044] Step 2102, storing each bitmap in the print queue according to the print order;

[0045] The print queue is pre-built, and the size of the print queue is allocated according to the number of constructed bitmaps, which are stored according to the positional relationship of the bitmaps, that is, the adjacent storag...

Embodiment 3

[0083] The scheme of adjusting the belt tightness according to the tension adjustment value is described above, but in the specific adjustment process, if only a single tension adjustment value is adjusted, an adjustment error will occur, for example, the belt is too tight or too loose. Therefore, the following improvement scheme is proposed.

[0084] Step 310, establishing a tension set in advance;

[0085] The tension set F stores N tension arrays f (T i , S i ), where T i is the tension adjustment value, S i is the actual adjustment value, S i To characterize the actual adjustment degree of the belt, the tension set F can be pre-built by the staff and obtained by monitoring the actual working condition of the system.

[0086] Step 320, sorting the tension arrays in the tension set;

[0087] According to the tension adjustment value T i sorted by size.

[0088] Step 330: Cut out the sorted tension array every predetermined length to obtain L subsets M.

[0089] Subs...

Abstract

The invention discloses a printing die cutting tension automatic control system and control method. The method comprises the following steps of responding to an image printing request, and according to an image bitmap, adjusting printing parameters; according to the printing parameters, executing printing operation; and obtaining tension parameters of paper after printing; and according to the tension parameters, adjusting the elastic degree of the belt. The printing die cutting tension automatic control system and method can achieve automatic control over the printing die cutting, bitmap information in the image is extracted, the position of the printing image is adjusted through a controller, and tension generated during printing can be avoided.

Description

technical field [0001] The application relates to the field of automatic control, and in particular, to an automatic control system for printing die-cutting tension and a control method thereof. Background technique [0002] In the existing tension control system, for the processing objects with tension, such as paper, film, steel, etc., the means to solve the tension problem are as follows: [0003] The first way is to use a software formula to calculate whether the volume of the object to be processed has changed, so as to determine whether there is a tension problem, such as CN107918723A, in which a tension controller is used to calculate the change of the roll diameter. There will be errors in the calculation of material and roll diameter. Through the judgment of tension logic, the error can be debugged and compensated. [0004] The second way is to use a positioning device or artificial flattening, that is, try to make the printed matter as flat as possible and try to ...
