Description

Technical Field

[0001] This utility model relates to the field of color printing technology, and in particular to a high-precision laminating device for a color printing machine. Background Technology

[0002] In the printing and packaging industry, lamination is a crucial technical step. This process involves covering the surface of printed products with a transparent plastic film, which not only improves the product's abrasion resistance, water resistance, and gloss, but also protects the printed patterns and enhances the product's visual appeal and texture. As a result, it is widely used in the production of various brochures, packaging boxes, book covers, and other printed materials.

[0003] In the traditional lamination process for color printing products, the surface temperature of the printed products is relatively high after lamination. This is because the adhesive used in the lamination process reacts with the printed products and the film under heating conditions. The high temperature causes the adhesion and curing between the printed products and the film to be slow and uneven, resulting in stress inside the film layer, which in turn causes problems such as blistering and wrinkles. This not only damages the appearance quality of the product and reduces its grade, but may also affect the performance of the product. Therefore, we have launched a new high-precision lamination device for color printing machines. Utility Model Content

[0004] The main objective of this invention is to provide a high-precision laminating device for color printing machines, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A high-precision laminating device for a color printing machine includes a laminating device body. Support feet are fixedly installed at the four corners of the lower end of the laminating device body. A support base is fixedly connected to the upper front part of the laminating device body. An extension platform is fixedly connected to the upper end of the support base. Extension plates are fixedly connected to the front left and front right ends of the extension platform. A displacement mechanism is fixedly installed at the rear ends of the two extension plates. A cooling mechanism is fixedly installed inside the displacement mechanism.

[0007] Preferably, the cooling mechanism includes a cold air box, the lower part of which has a groove, and a plurality of air outlet pipes are fixedly installed on the groove wall. A cold air fan is fixedly installed at the left and right ends of the cold air box, and a connecting pipe is fixedly installed at the output ends of the two cold air fans.

[0008] Preferably, the cold air box has a hollow structure and is located above the extension platform, with several air outlet pipes distributed at equal distances.

[0009] By adopting the above technical solution, the air outlet pipes with equal spacing ensure uniform cooling of the paper surface, improving the flatness and adhesion of the laminated product.

[0010] Preferably, the ends of the two connecting pipes furthest from the air cooler are fixedly connected to the upper part of the outer surface of the air cooler box, and both connecting pipes are connected to the inside of the air cooler box.

[0011] By adopting the above technical solution, the cold air generated by the air cooler can be sent into the air cooler box through the connecting pipe.

[0012] Preferably, the displacement mechanism includes a motor and a sliding rod. A threaded rod is fixedly installed at the output end of the motor. A movable sleeve is movably connected to the outer surface of the threaded rod. A sliding sleeve is slidably connected to the outer surface of the sliding rod. Moving strips are fixedly connected to the outer surfaces of both the movable sleeve and the sliding sleeve. Fixed rings are fixedly connected to the upper ends of both moving strips. Two connecting strips are fixedly connected between the two fixed rings.

[0013] Preferably, the motor is fixedly installed behind the extension plate on the right side, the end of the threaded rod away from the motor is movably connected to the body of the coating device through a bearing, the front end of the sliding rod is fixedly connected to the extension plate on the left side, and the rear end of the sliding rod is fixedly connected to the body of the coating device.

[0014] Preferably, the inner walls of both fixing rings are fixedly connected to the cold air box, and the two fixing rings and the two connecting strips are an integral structure.

[0015] By adopting the above technical solution: by starting the motor, the two fixed rings can move the cold air box back and forth, so that the several air outlet pipes under the cold air box can move from the front of the paper to the back of the paper for overall cooling.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. Move the laminated printed product to the extension table. Turn on the air cooler and send cold air into the air cooler box through the connecting pipe. The air outlet pipes at equal intervals at the bottom spray the laminated printed product in a directional manner to cool it. This allows the adhesive to solidify quickly after lamination, preventing problems such as bubbling, wrinkling or peeling of the film due to excessive temperature. At the same time, the equal-distance air outlet ensures uniform cooling of the surface of the printed product, improving the flatness and adhesion of the laminated product.

[0018] 2. After the laminated printed product has cooled down, start the motor. Driven by the motor, the two fixed rings can move the cold air box back and forth. This allows the several air outlets under the cold air box to move from the front to the back of the printed product for overall cooling. This avoids insufficient cooling in some areas due to the large size of the printed product. The dynamic movement ensures that the contact time between the cold air and the surface of the printed product is consistent, so that the adhesive between the laminate and the printed product is evenly cured across the entire surface.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Please see Figure 1-4 This utility model provides a technical solution:

[0028] A high-precision laminating device for a color printing machine includes a laminating device body 1. Support feet 2 are fixedly installed at the four corners of the lower end of the laminating device body 1. A support base 3 is fixedly connected to the upper front end of the laminating device body 1. An extension platform 4 is fixedly connected to the upper end of the support base 3. Extension plates 5 are fixedly connected to the front left and front right ends of the extension platform 4. A displacement mechanism 6 is fixedly installed at the rear end of each of the two extension plates 5. A cooling mechanism 7 is fixedly installed inside the displacement mechanism 6.

[0029] In this embodiment, the cooling mechanism 7 includes a cold air box 71. A groove 72 is provided in the lower part of the cold air box 71. Several air outlet pipes 73 are fixedly installed on the groove wall of the groove 72. A cold air fan 74 is fixedly installed at the left and right ends of the cold air box 71. A connecting pipe 75 is fixedly installed at the output end of the two cold air fans 74. The cold air box 71 is a hollow structure and is located above the extension platform 4. The several air outlet pipes 73 are distributed at equal distances. The ends of the two connecting pipes 75 away from the cold air fans 74 are fixedly connected to the upper part of the outer surface of the cold air box 71, and the two connecting pipes 75 are connected to the inside of the cold air box 71.

[0030] The above solution involves moving the laminated printed product onto the extension table 4, activating the air cooler 74, and sending cold air through the connecting pipe 75 into the air cooler box 71. The air outlets 73, evenly distributed at the bottom, spray cool air onto the laminated printed product in a directional manner, allowing the adhesive to solidify quickly after lamination. This prevents problems such as bubbling, wrinkling, or peeling of the film due to excessive temperature. At the same time, the evenly distributed air outlets ensure uniform cooling of the printed product surface, improving the flatness and adhesion of the laminated product.

[0031] In this embodiment, the displacement mechanism 6 includes a motor 61 and a sliding rod 62. A threaded rod 63 is fixedly installed at the output end of the motor 61. A movable sleeve 64 is movably connected to the outer surface of the threaded rod 63. A sliding sleeve 65 is slidably connected to the outer surface of the sliding rod 62. Moving strips 66 are fixedly connected to the outer surfaces of both the movable sleeve 64 and the sliding sleeve 65. Fixed rings 67 are fixedly connected to the upper ends of both moving strips 66. Two connecting strips 68 are fixedly connected between the two fixed rings 67. The motor 61 is fixedly installed behind the extension plate 5 on the right side. The end of the threaded rod 63 away from the motor 61 is movably connected to the coating device body 1 through a bearing. The front end of the sliding rod 62 is fixedly connected to the extension plate 5 on the left side, and the rear end of the sliding rod 62 is fixedly connected to the coating device body 1. The inner walls of the two fixed rings 67 are fixedly connected to the cold air box 71, and the two fixed rings 67 and the two connecting strips 68 are an integral structure.

[0032] The above solution involves starting the motor 61, which drives the two fixed rings 67 to move the cold air box 71 back and forth, allowing the several air outlet pipes 73 below the cold air box 71 to move from the front to the rear of the printed product for overall cooling.

[0033] It should be noted that this utility model is a high-precision laminating device for a color printing machine. During use, the color-printed product after lamination is transferred to the extension table 4. Then, the cooling fan 74 is activated, and the cold air generated by the fan 74 is delivered to the cooling box 71 via the connecting pipe 75. The cold air is then directionally sprayed from the air outlet pipes 73 evenly spaced at the bottom of the cooling box 71, cooling the laminated color-printed product. In this way, the adhesive can quickly cure after lamination, avoiding quality problems such as blistering, wrinkling, or peeling caused by excessively high film temperature. Simultaneously, the evenly spaced air outlet pipes 73 ensure uniform cooling of the color-printed product surface, thereby improving the flatness and adhesion of the laminated product. During the cooling operation, the motor 61 is started, and the motor 61 drives the threaded rod 63 to rotate. When the threaded rod 63 rotates, the movable sleeve 64 moves back and forth along the threaded rod 63. At the same time, the sliding sleeve 65 also moves back and forth synchronously on the sliding rod 62. This series of actions enables the two fixed rings 67 to drive the cold air box 71 to move back and forth, thereby allowing the multiple air outlet pipes 73 below the cold air box 71 to move from the front of the printed product to the rear of the printed product, thus cooling the printed product as a whole. This solves the problem of insufficient local cooling caused by the large size of the printed product. The dynamic movement ensures that the contact time between the cold air and the surface of the printed product is consistent, so that the adhesive between the lamination and the printed product is uniformly cured throughout the entire area.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
