Description

Technical Field

[0001] This utility model relates to the technical field of gravure ink drying equipment, specifically a rapid drying device for gravure ink on a laminating machine. Background Technology

[0002] As is well known, a laminating machine is a device that can bond two or more layers of materials together with adhesives, thereby giving the original materials new functions. It is frequently used for laminating materials such as films and aluminum foil, films, paper, and non-woven fabrics. It can also be used to laminate films, sponges, and cloths. Currently, most laminated products require gravure printing of trademarks after lamination, and the printed ink needs to be dried and set before packaging.

[0003] Traditional laminating machines have a recirculating drying device, but some of the laminated paper has darker ink. In the same amount of time, the darker ink is not completely dried. Packaging the workpiece before the ink has fully dried can easily affect the overall quality of the product. Therefore, a lot of extra time is required for drying. Packaging can only be done after all the ink has dried, which undoubtedly leads to a decrease in production efficiency and is not conducive to user use.

[0004] A rapid drying device for gravure printing inks on a multilayer machine, disclosed in CN216832812U, has its drying unit directly mounted on a base with a fixed spacing between it and the printed product, offering no flexibility for adjustment. In actual production, various types of paper need to be processed, and these papers differ in thickness, material, moisture content, and the area of ​​the printed pattern, resulting in varying drying requirements. This fixed-spacing design struggles to meet the drying needs of diverse paper types, potentially leading to over-drying of some papers, causing embrittlement and discoloration, thus affecting print quality. Conversely, for thicker papers or those with higher moisture content, insufficient drying may result in uneven drying and excessively long drying times, reducing production efficiency. Therefore, improvements are urgently needed to adapt to the drying requirements of different papers and enhance the overall processing quality and efficiency of printed products.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides a rapid drying device for gravure printing ink in a laminating machine, which has the following beneficial effects:

[0019] This rapid drying device for gravure printing inks on a multilayer machine utilizes a rotatable mounting frame on a support structure. Drying devices are located at the top and bottom of the mounting frame, and the printed materials pass between these devices for drying. When the mounting frame is rotated, the upper and lower drying devices rotate synchronously, allowing for easy adjustment of the distance between the drying devices and the printed materials, making operation convenient. This allows the drying device to precisely adjust the drying spacing according to the characteristics of different printed materials (such as various types of paper), avoiding under-drying or over-drying, greatly improving the uniformity and stability of drying, effectively ensuring the quality of the printed materials, reducing the scrap rate, and also increasing drying efficiency while reducing energy consumption.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 This utility model discloses a rapid drying device for gravure printing ink on a laminating machine, comprising a support frame 1, a base 12 at the bottom of the support frame 1, a connecting shaft 7 rotatably connected to the support frame 1, and a mounting frame 2 fixedly connected to a fixed shaft. The mounting frame 2 can rotate relative to the support frame 1. Drying devices 3 are provided at both the top and bottom of the mounting frame 2. Printed products 4 pass between the top and bottom drying devices 3, thus achieving the drying of the printed products 4. When the mounting frame 2 is rotated, the upper and lower drying devices 3 rotate synchronously, allowing easy adjustment of the distance between them and the printed products 4, making operation convenient. This enables the drying devices 3 to precisely adjust the drying distance according to the characteristics of different printed products 4 (such as various types of paper). The drying device 3 can be a heating shaft or an infrared drying lamp, etc., any device capable of drying printed products 4.

[0028] To further enhance safety, a protective cover 5 is installed on the outside of the drying device 3. An opening is provided on one side of the protective cover 5 to allow heat to dissipate. The protective cover 5 and the mounting bracket 2 are rotatably connected to facilitate adjustment of the opening position. A mesh 6 is provided at the opening of the protective cover 5 to provide protection.

[0029] A crank 8 is provided on the connecting shaft 7. The mounting bracket 2 can be rotated by turning the crank 8 by hand.

[0030] A connecting block 10 is provided on the support frame 1. A set screw 11 is connected to the connecting block 10 by a thread. The screw-in end of the set screw 11 can abut against the outer wall of the connecting shaft 7. Tightening the set screw 11 fixes the set screw 11 to the connecting shaft 7, thereby fixing the position of the mounting frame 2 and preventing the mounting frame 2 from rotating.

[0031] In order to accurately adjust the mounting bracket 2, the support bracket 1 is equipped with scale lines 9, and the connecting shaft 7 is equipped with reference lines.

[0032] In summary, this rapid drying device for gravure printing ink in a multilayer machine allows the printed product 4 to be carefully passed between the top drying device 3 and the bottom drying device 3 during use. Depending on the type of printed product 4 (such as paper thickness and material), rotating the mounting bracket 2 brings the top and bottom drying devices 3 closer to the printed product 4, while rotating them in the opposite direction increases the distance. During adjustment, the distance between the drying device 3 and the printed product 4 can be precisely set by observing the scale line 9 on the device and the position of the reference direction to achieve the best drying effect.

[0033] Then tighten the set screw 11 so that the screw-in end of the set screw 11 is opposite to the outer wall of the connecting shaft 7. The set screw 11 fixes the connecting shaft 7 to fix the position of the mounting bracket 2 and prevent the mounting bracket 2 from rotating.

[0034] After adjustment, power is turned on the drying device 3, and the drying device 3 starts to work. The top and bottom drying devices 3 heat up at the same time, generating hot air to dry the printed products 4.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
