Description

Technical Field

[0001] The utility model belongs to the technical field of surface treatment devices for conveying or guiding roll paper through a printing press or machine or B41F23 / 00 single paper, roll paper or other printing-related articles in IPC classification B41F13 / 02, and particularly relates to a structural innovation and improvement technology of a multifunctional device which is not only suitable for cardboard and roll paper rollers in a printing and laminating process, but also adapts to a variety of working conditions such as cold / hot air flow processing. Background Art

[0002] Lamination is a process of covering the surface of printed matter with a plastic film and bonding them together through adhesives after heating and pressurization. Lamination can be divided into two types: semi-laminated and glossy laminated. Semi-laminated is not as glossy as glossy but more upscale. Lamination can enhance the moisture-proof, sun-proof, wear-resistant, anti-fouling, water-resistant, and heat-resistant properties of printed matter.

[0003] In the prior art, lamination treatment is widely used on printed materials to cover their surface with a thin and transparent plastic film. The lamination process is divided into hot lamination and cold lamination. Hot lamination can be firmly covered on the surface of paper after hot pressing. The film material used in cold lamination is a special plastic film material that can be pressed onto the surface of paper without heating. The material cost is lower, and the lamination process is simpler, more energy-saving and environmentally friendly.

[0004] Traditional lamination is a major process in post-printing processing. It is a process of bonding a plastic film coated with adhesive to a paper printed matter after heating and pressurizing to form a paper-plastic integrated product. It is one of the most common post-printing processing technologies for paper printed matter. The laminated printed matter has a smoother and brighter surface due to the addition of a thin and transparent plastic film, which not only improves the gloss and fastness of the printed matter and extends the service life of the printed matter, but the plastic film also plays a protective role in terms of moisture-proof, waterproof, anti-fouling, wear-resistant, fold-resistant, and chemical corrosion-resistant.

[0005] There are many types of technologies in the laminating process. For example, there are also glossy and matte laminating. This is for different products and different paper types. Generally, if the product needs a smooth feeling, it must be coated with a glossy film. If the product needs a matte finish, it must be coated with a matte film. The laminating effect is to heat and pressurize the plastic film coated with adhesive and bond it with the paper printed matter to form a paper-plastic product. It is one of the common post-printing processing technologies for paper printed matter. The printed matter after laminating has a thin and transparent plastic film on the surface, which makes the surface smoother and brighter. It not only improves the gloss and fastness of the printed matter, but also prolongs the service life of the printed matter. At the same time, the plastic film also plays a protective role in moisture-proof, waterproof, anti-fouling, wear-resistant, folding-resistant, and chemical corrosion-resistant. For example, for the printed materials to be processed, the hardness can be roughly divided into softer rollable materials and harder corrugated boards, coated paper and other plates.

[0006] More patent applications for corresponding improved technologies have been published over the Chinese New Year. For example, patent application 202011348423.4 involves a printing production laminating machine, including a workbench, a laminating device and a belt conveyor. The laminating device is fixedly installed on the upper end of the workbench, and belt conveyors are symmetrically installed on the left and right sides of the workbench. The laminating device includes a fixed plate, a positioning roller, a laminating cylinder, a baffle cylinder, guide roller one, guide roller two, motor one, extrusion roller, a cleaning frame and a heat pipe.

[0007] In the prior art, there is no laminating machine that can adapt to printing materials of different hardness and take into account both cold and hot lamination on the same device. There are many reasons for this, including limitations in the structural design of the equipment and the lack of targeted pretreatment of the laminating materials and a laminating process structure that can be adjusted and controlled online. For example, when laminating printed corrugated paper sheets, it is necessary to manually place the corrugated paper sheets on the conveyor belt of the laminating machine. In this way, the laminating machine needs to be equipped with a feeding worker when it is working, and it cannot load automatically. The degree of automation is low, resulting in labor waste and increased production costs. For another example, when a traditional printing production laminating machine is laminating the surface of a printed product, the film is heated before contacting the printed product. It is very easy for the temperature to rise rapidly, resulting in the film surface being heated too quickly, resulting in slight deformation, thereby affecting the lamination quality. For example, when a conventional printing product laminating machine performs lamination on the surface of a printed product, impurities are easily attached to the surface of the part that heats the surface of the film, thereby affecting the lamination quality of the film. At the same time, the heat generated by the heated part can only heat the film, resulting in a low heat utilization rate. In short, no widely applicable printing laminating equipment technology has been disclosed. Utility Model Content

[0029] The application of vortex tubes in the printing field will become more and more extensive and in-depth. Vortex tube refrigeration does not require the use of chemical refrigerants such as Freon, does not produce harmful emissions, and meets environmental protection requirements. At the same time, the vortex tube refrigeration system has a simple structure, easy maintenance, and low operating cost, which helps to reduce the operating costs of printing companies. The vortex tube is a device that uses compressed air to generate cold and hot air. Its working principle is based on the law of conservation of energy and the principle of thermodynamics. It achieves cold and hot separation through the expansion and energy conversion of compressed air. Inside the vortex tube, the compressed air is rotated at high speed and forms a vortex. The temperature at the center of the vortex decreases to form cold air, while the temperature of the periphery of the vortex increases due to the expansion of the compressed air to form hot air. This characteristic of cold and hot separation makes the vortex tube widely used in many fields. In addition, the application of vortex tubes in the printing industry also reflects its environmental protection and energy-saving characteristics.

[0033] Furthermore, an auxiliary atmosphere nozzle 14 is installed at the rear side of the lamination roller 6 , and the auxiliary atmosphere nozzle 14 is connected to the temperature regulating gas distribution box 12 .

[0034] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0035] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.

[0036] The content of the present invention can be more easily understood by selecting the following preferred implementation methods and embodiments of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by ordinary technicians in the field to which the present invention belongs. When there is a conflict, the definition in this specification shall prevail.

[0037] Embodiment 1: As attached Figure 1 As shown, when it is necessary to thermally coat the surface of the hard printing material 8 with the film peeled off from the film-carrying roll 3; the film-carrying roll 3 rolled out of the film supply roller 1 is pulled to bypass the pretreatment traction roller 4 and the upper front guide roller 5 in succession, pass between the film pressing roller 6 and the temperature-controlled driving roller 16, and then bypass the upper rear guide roller 7 and be rolled back onto the paper-carrying recovery roller 9; the hard printing material 8 cardboard passes between the film pressing roller 6 and the temperature-controlled driving roller 16 from the lower side of the film-carrying roll 3 along the top of the front paper feeding roller 17. At the same time, the film pressing roller 6 and the temperature-controlled driving roller 16 rotate synchronously, and push the printing material 8 cardboard to move toward the rear supporting traction roller 18 by extrusion in the same direction on the outer section. At the same time, the film peeled off from the film-carrying roll 3 is tightly attached to the printing material 8 under the extrusion and thermal action of the film pressing roller 6 and the temperature-controlled driving roller 16, and is supported and output by the rear supporting traction roller 18, and the base film on the film-carrying roll 3 bypasses the upper rear guide roller 7 and is rolled back onto the paper-carrying recovery roller 9.

[0038] In the above, the temperature-controlled air distribution box 12 includes a cold air input pipe, a hot air input pipe, a three-way pipe, a distribution temperature-controlled output pipe and a corresponding automatic solenoid valve. Further, the temperature-controlled air distribution box 12 is equipped with an air flow velocity meter, an air temperature meter and a remote management device.

[0039] In the above, the upper rear guide roller 7 is connected to the lifting control device through a transmission mechanism. The upper rear guide roller 7 can elastically tension the film-carrying roll 3, and can also lower the position to press the film-carrying roll 3 to fit the printing material 8 more closely as needed.

[0040] In the above, the surfaces of the lamination roller 6 and the temperature-controlled driving roller 16 have heat-conducting friction sleeves.

[0041] In the embodiment of the utility model, the pretreatment traction roller 4, the upper front guide roller 5 and the upper rear guide roller 7 cooperate with the film pressing roller 6 to guide and tighten the film-carrying roll 3 and the film, and preheat and heat the film, so that the film is in close contact with the printed matter and quickly bonded.

[0042] In the embodiment of the utility model, the pretreatment traction roller 4 pulls the film-carrying paper 3 forward and, at the same time, cleans the surface of the film-carrying paper 3; correspondingly, the upper externally cut temperature regulating roller 13 further cleans the surface of the film-pressing roller 6 during the mutual rolling, extruding and heat transfer process with the film-pressing roller 6, and the lower externally cut temperature regulating roller 15 further cleans the surface of the temperature-controlled driving roller 16 during the mutual extruding, heat transfer and rolling process with the temperature-controlled driving roller 16.

[0043] In the embodiment of the utility model, the pretreatment traction roller 4 is externally installed with a cleaning roller, and the surface of the cleaning roller is covered with a static-removing impurity-absorbing felt that is cleaned regularly. Alternatively, a jet pipe is led out from the temperature-adjusting air distribution box 12 to use airflow to blow and wash the surface of the film-carrying roll 3.

[0044] In the embodiment of the utility model, the air compressor 10, i.e., the air compressor 3, is a machine device that compresses air into high-pressure gas. It increases the pressure and density of the air by reducing its volume, so that the air can be stored and used more efficiently. The working principle of the air compressor generally involves an electric motor driving the compressor, causing the crankshaft to rotate, driving the connecting rod to cause the piston to reciprocate, thereby changing the cylinder volume to compress the air. Modern, especially screw-type air compressors, may reduce the volume by rotating a screw or other similar structure to compress the gas.

[0045] In the embodiment of the utility model, the vortex tube 11 is also called a vortex tube, a vortex refrigerator, etc. After the compressed air of a certain pressure is input into the vortex generator of the vortex tube, it expands and accelerates and then rotates. The airflow enters the heat pipe along the wall of the heat pipe at a rotation speed of 1,000,000rpm. The airflow in the heat pipe generates energy conversion after the vortex exchange. The airflow is divided into two streams of cold and hot air. At the terminal of the heat pipe, a part of the compressed air is discharged in the form of hot air through the regulating valve, and the remaining compressed air returns at a lower speed through the center of the rotating airflow entering the heat pipe. This cold airflow passes through the center of the generator to form ultra-low temperature cold air and is collected at the cold air end for discharge. The cold air end ejects the cold air flow at 7Bar, 25℃ dry air, and the minimum cold air temperature can reach -35℃, and the maximum temperature drop can reach 40℃. The limit temperature of the hot air flow ejected from the other end can reach +180℃. During the operation of the vortex tube 4, only factory compressed air is needed, which is cheap, does not require expensive equipment, and has low cost. The vortex tube 4 is easy to operate and use, lightweight and portable, maintenance-free, safe, and has a long service life. No chemical enzymes such as Freon, no residual waste to clean up, no electricity, and no sparks.

[0046] In this embodiment, the temperature-controlled gas distribution box 12 precisely controls the flow of various gases and mixes them using a mass flow meter and other equipment to achieve the required ratio concentration. The temperature-controlled gas distribution box 12 adopts a reasonable structure and a stable and reliable control method, such as a refrigeration technology such as a reverse Carroll cycle, combined with a PID automatic calculation output to control the output of the heater, to achieve precise regulation of the temperature inside the box.

[0047] The design and manufacture of the temperature control and gas distribution box 12 generally comply with standard specifications GB15322.1~3-2019, GB / T34004-2017, CJ / T347-2010, etc. These standards specify the performance requirements, test methods, inspection rules, etc. of the test equipment to ensure that the temperature control and gas distribution box can meet various test requirements.

[0048] Preferably, the vortex tube 11 uses WA0-020 model products, supplies compressed air at 70℉ (21.1℃), the outer diameter of the vortex chamber body is 30mm, the cold air flow output temperature is -40℃, and the hot air flow output is 230℉ (110℃); the air intake volume is 20cfm / 0.698BAR, and the steam consumption is 0.85m 3 / min, cooling capacity 2100BTU / Hr.

[0049] Example 2: When it is necessary to cold-coat the surface of a hard printing material 8 with a film peeled off from the film-carrying roll 3; refer to Example 1, as shown in the attached Figure 2 As shown, the upper external temperature regulating roller 13 and the lower external temperature regulating roller 15 accurately control the surface temperature, and the upper rear guide roller 7 presses down, so that the film peeled off from the film-carrying roll 3 is evenly and finely covered on the surface of the printing material 8, and either the film pressing roller 6 and the temperature-controlled driving roller 16 assist in extrusion, or the air flow of the auxiliary atmosphere nozzle 14 is blown to transfer the film peeled off from the film-carrying roll 3 to the hard printing material 8 cardboard.

[0050] In the embodiment of the utility model, there are actually unfavorable environmental factors in the cold lamination process. For example, in the printing equipment, some key components such as motors and bearings will generate a lot of heat during operation. If the heat cannot be dissipated or cooled down in time, it may cause the equipment to overheat, performance degradation or even damage, and further affect the quality of the cold lamination composite operation. In this embodiment, the auxiliary atmosphere nozzle 14 can generate a cold air flow to cool these key components at the same time to ensure the cold lamination effect, and it is also conducive to ensuring the normal operation of the equipment and extending its service life.

[0051] Embodiment 3: When it is necessary to coat the surface of a soft printing material 8 with a film peeled off from the film carrier roll 3; Figure 3 As shown, the traction process of the film-carrying paper roll 3 refers to Example 1; the soft printing material 8 is rolled around the front paper feed roller 17, then around the lower traction guide roller 20, and then rolled from the lower side of the film-carrying paper roll 3 through the film pressing roller 6 and the temperature-controlled drive roller 16, and then rolled around the lower rear guide roller 21, and finally rolled back to the printing paper recovery roller 19.

[0052] In the above, the printing material 8 is guided and pulled by the lower traction guide roller 20 and the lower rear guide roller 21, so that the printing material 8 is tightened and flat, which is conducive to obtaining the best lamination effect.

[0053] In addition, the application of the vortex tube 4 in the printing industry of this embodiment also reflects its environmental protection and energy-saving characteristics. The vortex tube 4 refrigeration does not require the use of chemical refrigerants such as Freon, does not produce harmful emissions, and meets environmental protection requirements. At the same time, the vortex tube 4 refrigeration system has a simple structure, convenient maintenance, and low operating cost, which helps to reduce the operating costs of printing companies.

[0054] Based on the above embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention, so as to avoid exhaustively listing all implementation methods that are unnecessary and impossible to list comprehensively.
