Detailed Description
The technical solutions of the present invention will be clearly and completely described in connection with the embodiments, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention. It is noted that relational terms such as "first" and "second", and the like, are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.
Referring to fig. 1, the invention provides a digital printing dual-cold-wave control system, which comprises a printing module, a first processing module, a second processing module and a control module. The control module is respectively in communication connection with the printing module, the first processing module and the second processing module.
In the digital printing double-cold-stamping control system, the double-cold-stamping is realized by a cold-stamping process, namely a film laminating device and a gold stamping device. Wherein, the coating film is to attach a layer of transparent and sticky film material on the surface of the bearing material for increasing gloss, improving hardness and protecting the bearing material. Cold stamping is a printing processing technology, and a metal color is hot stamped on the surface of a printed matter by using a cold stamping coating and a tobacco foil so as to increase the visual effect and texture of the printed matter. Unlike traditional hot stamping, cold stamping does not require heating to adhere the stamping foil to the print, and is therefore referred to as cold stamping.
In the application, the first processing module is a film laminating device or a gold stamping device; if the first processing module is a film laminating device, the second processing module is a gold stamping device; if the first processing module is a gold stamping device, the second processing module is a film laminating device.
The control module comprises a parameter storage module, an equipment identification module and an instruction transmission module; the parameter storage module stores a plurality of key value pairs; the equipment identification module is used for identifying the first processing module and the second processing module and acquiring process setting parameters of the first processing module and the second processing module; the instruction transmission module generates a first control instruction and a second control instruction according to the process setting parameters and the key value pairs;
the printing module adopts a digital printing technology to print design patterns on a printing material and transmits the printing material to the laminating device;
the first processing module executes a first processing operation according to a first control instruction and transmits a printing material to the second processing module;
and the second processing module executes a second processing operation according to a second control instruction.
The first processing module and the second processing module are configured, so that the positions of the laminating device and the gold stamping device are flexibly interchanged. Specifically, when the first processing module is a film laminating device, the second processing module may be a gold stamping device; conversely, when the first processing module is a gold stamping device, the second processing module may be a film laminating device. Therefore, the processing sequence of using the laminating and gilding can be selected according to different processing demands, and the laminating and gilding processing sequence is identified through the equipment identification module, so that different product processing demands can be met, and a user does not need to be equipped with digital printing double-cold-stamping equipment with two procedures of laminating-gilding and gilding-laminating.
Further, in the practical application process of the digital printing dual cold wave device, different processing sequences bring different effects, so that the processing needs to be performed. In the first aspect, for the process flow of film coating and then gold stamping, the problem exists in the gold stamping of the electrochemical aluminum, namely if the surface tension of the film coating material is very low, the electrochemical aluminum can not be stamped, and the gold stamping effect is incomplete. This is because the low surface tension can cause the bronzing material to fail to adhere to the film surface, thereby affecting the bronzing effect. In the second aspect, for the process flow of gold stamping and then film coating, the film coating glue may cause black spots to appear in gold stamping and oxidation. This is because some glue components, such as certain solvents, may oxidize some of the bronzing material, resulting in black spots in the bronzing. In addition, when in gold stamping, pressure needs to be applied, so that certain embossing is caused, and the uniformity and quality of the coating are further affected, so that the pressure of the coating needs to be adjusted under different working conditions.
In order to solve the problems, the process setting parameters at least comprise a laminating material model, a gold stamping layer thickness and a glue model; the key value pair comprises a laminating material model-a gold stamping material model, a gold stamping layer thickness-a laminating pressure parameter and a glue model-a gold stamping material model; wherein, the explanation of the effect of each key value is as follows:
film coating material model-gold stamping material model: in the technological process of firstly laminating and then stamping, the surface tension and the adhesion performance of different materials are different, and when the film laminating material is used for cold stamping, different laminating materials need to swing different stamping material models so as to ensure the quality and the integrity of the cold stamping effect.
Glue model-bronzing material model: in the technological process of gold stamping and then film coating, the glue and the gold stamping material can possibly generate oxidation and black spot reaction. Therefore, different processing parameters are required to be set according to different glue models and gold stamping material models so as to prevent black spots or other bad gold stamping effects.
Gilt layer thickness-laminating pressure parameter: in the technological process of gold stamping and then film coating, gold stamping layers have different thicknesses according to different design requirements of users. Therefore, when the gold stamping processing technology is designed, the actual thickness of the gold stamping layer needs to be calculated, and the corresponding laminating pressure is combined for processing, so that the pressurizing uniformity between the gold stamping material and the film material is ensured, and the uniformity and the quality of the laminating are improved.
According to the embodiment, the laminating material model-the gold stamping material model, the gold stamping layer thickness-the laminating pressure parameter and the glue model-the gold stamping material model are subjected to the preset key values, so that the problems existing in the process flow of laminating, gold stamping and laminating are solved, and the stability of the process flow can be improved effectively.
As a preferred embodiment, the digital printing double-cold-ironing control system further comprises a corona module; when the first processing module is a film laminating device, the film laminating material is subjected to corona treatment in advance. Corona treatment (Corona treatment) is a surface modification technique that increases the surface energy of a polymer by applying a high electric bright field (Corona discharge) to the surface, enhancing its adhesion to other objects. In this application, all of the coating material is subjected to a corona module prior to application of the coating material to the first processing module. The corona module is supported to be integrated with the laminating device or independently arranged. The corona treatment comprises the following steps:
polymer material treatment: cutting the film-covered material to be treated into proper size, placing it on the baffle plate or conveyer belt of corona device to ensure clean surface, no dust and no greasy dirt, etc.
Parameter setting: according to the properties of the film-covered material to be treated and the surface state thereof, parameters such as voltage, current, treatment speed and the like of corona treatment equipment are set.
The processing operation comprises the following steps: and starting corona treatment equipment, and treating the film-coated material by generating corona discharge through high voltage, so as to change the surface chemical structure, molecular arrangement and other properties of the film-coated material and enhance the surface energy and adhesive force of the film-coated material.
Measurement results: and testing the surface tension of the treated coating material by using instruments such as a surface tensiometer and the like, so as to ensure that the corona treatment effect meets the requirement.
As a preferred embodiment, the gold stamping device comprises a first tension adjusting roller and a first tension controller; the laminating device comprises a second tension adjusting roller and a second tension controller; the digital printing double-cold-ironing control system also comprises a third tension adjusting roller and a third tension controller; the third tension adjusting roller is arranged between the printing module and the first processing module and is used for adjusting the tension of the printing material. Specifically, the first tension controller, the second tension controller and the third tension controller respectively sense the tension of the gold stamping material, the film coating material and the printing stock through the sensors. The first tension controller, the second tension controller and the third tension controller respectively control the movement of the first tension adjusting roller, the second tension adjusting roller and the third tension adjusting roller through a PID algorithm according to the difference between the preset tension requirement and the actual tension signal, so that the tension is adjusted.
As a preferred embodiment, the digital printing dual cold wave control system further comprises a displacement adjustment module; the displacement adjusting module comprises a first displacement adjusting module, a second displacement adjusting module and a third displacement adjusting module; the first displacement adjusting module is integrated with the gold stamping device and connected with the first tension adjusting roller; the second displacement adjusting module is integrated with the laminating device and connected with a second tension adjusting roller; the third displacement adjusting module is connected with a third tension adjusting roller. The first displacement adjusting module, the second displacement adjusting module and the third displacement adjusting module are respectively used for correcting the position deviation of the first tension adjusting roller, the second tension adjusting roller and the third tension adjusting roller. In the foregoing embodiment, the tension controller controls the movement of the corresponding dancer roll via a PID algorithm. During the movement of the dancer roll, the positional deviation caused by the movement thereof will continue to accumulate, and thus the tension control accuracy of the solution achieved by the dancer roll alone is not ideal. In order to solve the problem, the present embodiment provides a displacement adjustment module, where the first displacement adjustment module, the second displacement adjustment module, and the third displacement adjustment module are all provided with a displacement sensor and a displacement controller; the displacement sensor is used for acquiring offset voltage signals generated by the tension adjusting roller and transmitting the offset voltage signals to the displacement controller, and the displacement controller controls the position of the corresponding tension adjusting roller according to the corresponding offset voltage signals. In this embodiment, each displacement adjustment module may independently control the position of the respective tension adjustment roller, and the displacement adjustment module senses an offset voltage signal generated by the tension adjustment roller through a displacement sensor and controls the position of the tension adjustment roller through a displacement controller. Therefore, the position of the tension adjusting roller can be accurately adjusted, and the tension in the printing process is accurately adjusted. This helps to maintain the stability of the printed material, ensuring the quality and accuracy of the printed product.
As a preferred embodiment, referring to fig. 2, the digital printing dual cold stamping control system further comprises a UV curing lamp for curing the printing material after the laminating and stamping operations. UV curing lamps are a special type of ultraviolet light emitting lamp that promotes the rapid curing reaction of the glue by irradiating high energy ultraviolet light onto the substrate, thereby forming a hard, durable coating.
Further, the key value pairs stored by the parameter storage module also comprise printing material model-curing lamp power. When the coating is cured using a UV curing lamp, the power of the curing lamp and the color of the underlying material may affect the curing speed and effect. In a first aspect, the light energy of the curing light is related to the color and thickness of the support material, and the light passing through the thickness of the support material has a different effect on the color. Generally, lighter colors absorb less light and darker colors absorb more light, so the dark color bearing material cures slower, while the light color bearing material cures faster. In the second aspect, the power of the curing lamp directly affects the curing effect, and generally, the higher the power, the better the curing effect. However, although the high power curing lamps may significantly improve the curing effect, special attention is required at the time of use because an excessively high rate may cause yellowing or other distortion phenomenon of the support material and result in deterioration of the curing effect. It is necessary to appropriately reduce the power of the curing lamp or to select an appropriate curing lamp to secure the curing effect. According to the embodiment, the printing material model and the curing lamp power are bound, the system can automatically identify the used printing material model, and the preset adaptive curing lamp power does not need manual intervention, so that the automation level of equipment is improved.
