Description

Technical Field

[0001] This utility model belongs to the field of printing and coating machinery, and in particular to an ultra-thin material printing and coating production line. Background Technology

[0002] With the advancement of technology, more and more precision equipment and products are being manufactured. These precision equipment and products typically have high requirements for raw materials. Ultra-thin films and ultra-thin papers, as commonly used industrial raw materials, are being used more and more widely in various fields. However, existing printing and coating equipment is ill-suited for coating and printing ultra-thin materials. During the production process, ultra-thin materials are easily damaged and wrinkled, resulting in low production yields. Furthermore, because ultra-thin materials are easily damaged, production speed is also limited, affecting output capacity. Utility Model Content

[0003] To overcome the shortcomings of the existing products mentioned above, this utility model provides an ultra-thin material printing and coating production line that has a high production speed and is less likely to damage the ultra-thin material.

[0004] The technical solution adopted by this utility model to solve its technical problem is: The ultra-thin material printing and coating production line includes an unwinding mechanism 1, a single-sided dust removal mechanism 2, a printing and coloring mechanism 3, a first drying mechanism 4, a hot melt adhesive coating mechanism 5, a second drying mechanism 6, a traction cooling mechanism 7, and a winding mechanism 8 arranged in sequence. The pressure rollers 9 on the printing and coloring mechanism 3 and the hot melt adhesive coating mechanism 5, used to press the ultra-thin material 10 down for printing or adhesive application, are rotatably mounted at one end of a seesaw-type rocker arm 11. At the other end of the rocker arm 11, a guide roller 12 is rotatably mounted. The end of the rocker arm 11 containing the pressure roller is connected to the movable end of a drive cylinder 23 and is driven to swing. The ultra-thin material 10 is introduced from the guide roller 12 and then introduced below the pressure roller 9, i.e., between the pressure roller 9 and the paint / coloring roller 13 or the hot melt adhesive coating roller 14, for printing or coating. The rocker arm is hinged to a frame 24, and the cylinder is fixedly mounted on the frame.

[0005] Preferably, the single-sided dust removal mechanism 2 includes a liquid silicone dust removal roller 21 for contacting the printing surface of the ultra-thin material 10 and a knife-free adhesive paper roller 22, which is position-adjustable and driven by a cylinder, located behind the liquid silicone dust removal roller 21. When the surface of the liquid silicone dust removal roller 21 is dirty, the knife-free adhesive paper roller 22 is pushed by the cylinder to contact the liquid silicone dust removal roller 21 and remove the dirt. After the surface of the knife-free adhesive paper roller 22 is dirty, the adhesive paper can be peeled off. It is very convenient to use and the dust removal process is very gentle, which can protect the ultra-thin material from damage.

[0006] Preferably, an antistatic device 15, driven by a cylinder to move forward or backward, is provided between the hot melt adhesive coating mechanism 5 and the second drying mechanism 6. This device is used to remove static electricity from the ultra-thin material 10 to prevent dust from re-adsorbing onto the surface of the ultra-thin material and to prevent static electricity from causing fire.

[0007] Preferably, the unwinding mechanism 1 is a shaftless air-jacking unwinding mechanism.

[0008] Preferably, the second drying mechanism 6 is an oven, and the temperature inside the oven is 50-120℃.

[0009] Preferably, in the ultra-thin material printing and coating production line, the second drying mechanism 6 is located at the top, and the other mechanisms are located at the bottom to save floor space. Specifically, the unwinding mechanism 1, the single-sided dust removal mechanism 2, the printing and coloring mechanism 3, the first drying mechanism 4, and the hot melt adhesive coating mechanism 5 are arranged in sequence and located on one side below the second drying mechanism 6. The traction cooling mechanism 7 and the winding mechanism 8 are arranged in sequence and located on the other side below the second drying mechanism 6.

[0010] Preferably, a tension adjustment mechanism 16 is provided between the unwinding mechanism 1 and the single-sided dust removal mechanism 2, as well as between the traction cooling mechanism 7 and the winding mechanism 8.

[0011] Preferably, a cold air cooling mechanism 17 is provided at the rear end of the second drying mechanism 6 and the front end of the traction cooling mechanism 7 to facilitate rapid cooling of the ultra-thin material 10 coming out of the second drying mechanism 6, thereby ensuring the stability of the material's performance and dimensions.

[0012] Preferably, a correction mechanism 18 is provided between the first drying mechanism 4 and the hot melt adhesive coating mechanism 5, and between the second drying mechanism 6 and the traction cooling mechanism 7.

[0013] Preferably, a single-sided corona treatment mechanism 19 is provided between the single-sided dust removal mechanism 2 and the printing and coloring mechanism 3. The single-sided corona treatment mechanism 19 is an optional processing mechanism. The ultra-thin material 1 can be subjected to single-sided corona treatment by the single-sided corona treatment mechanism 19 to improve the surface energy of the surface to be printed and enhance the ink adhesion, while retaining the functional characteristics of the other side, or it can be bypassed.

[0014] Preferably, the rear end of the first drying mechanism 4 is also provided with a water-cooled roller 20 to reduce the temperature of the ultra-thin material as quickly as possible and ensure the stability of the material's performance and dimensions.

[0016] Preferably, the winding mechanism 8 is a dual-purpose winding mechanism for both flat and top pressure applications.

[0017] The beneficial effects of this utility model are: This utility model discloses an ultra-thin material printing and coating production line with an ingenious structure. During the printing and coating process, the lower pressure roller is positioned at one end of a seesaw-type rocker arm, and a guide roller is positioned at the other end of the rocker arm. When the lower pressure roller presses down, the guide roller rises. This ensures that the tension change on the ultra-thin material is minimal during the painting, coloring, or coating process. This minimal tension change protects the ultra-thin material from being strained when it comes into contact with and is pressed down by the lower pressure roller during painting, coloring, or adhesive application. Furthermore, it maintains a constant micro-tension on the material. If this micro-tension cannot be maintained on the ultra-thin material, it is prone to cracking. Wrinkles, especially when the material width is large, can affect the quality of painting, coloring, or coating. Therefore, this setting can both prevent wrinkles and protect ultra-thin materials from being stretched. Because of this, the production speed can also be appropriately increased. Therefore, this production line is suitable for printing and coating ultra-thin materials, and it is also suitable for printing and coating ultra-thin materials with larger widths. It has high production efficiency, stable finished product quality, and good yield. In particular, combined with reasonable tension adjustment, correction, reasonable dust removal, and timely cooling, it further improves the adaptability to the production of ultra-thin materials, improves product quality and production efficiency, and is highly practical and worthy of promotion.

Detailed Implementation

[0019] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0020] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0021] like Figure 1-5As shown, the ultra-thin material printing and coating production line includes an unwinding mechanism 1, a single-sided dust removal mechanism 2, a printing and coloring mechanism 3, a first drying mechanism 4, a hot melt adhesive coating mechanism 5, a second drying mechanism 6, a traction cooling mechanism 7, and a winding mechanism 8 arranged in sequence. The pressure rollers 9 on the printing and coloring mechanism 3 and the hot melt adhesive coating mechanism 5, used to press the ultra-thin material 10 down for printing or adhesive application, are rotatably mounted at one end of a seesaw-type rocker arm 11. At the other end of the rocker arm 11, a guide roller 12 is rotatably mounted. The end of the rocker arm 11 containing the pressure roller is connected to the movable end of a drive cylinder 23 and is driven to swing. The ultra-thin material 10 is introduced from the guide roller 12 and then introduced below the pressure roller 9, i.e., between the pressure roller 9 and the paint / coloring roller 13 or the hot melt adhesive coating roller 14, for printing or coating. The rocker arm is hinged to a frame 24, and the cylinder is fixedly mounted on the frame.

[0022] The single-sided dust removal mechanism 2 includes a liquid silicone dust removal roller 21 for contacting the printing surface of the ultra-thin material 10 and a knife-free adhesive paper roller 22, which is positioned and adjustable by a cylinder and is located behind the liquid silicone dust removal roller 21. When the surface of the liquid silicone dust removal roller 21 is dirty, the cylinder pushes the knife-free adhesive paper roller 22 to contact the liquid silicone dust removal roller 21 and remove the dirt. After the surface of the knife-free adhesive paper roller 22 is dirty, the adhesive paper can be peeled off. It is very convenient to use and the dust removal process is very gentle, which can protect the ultra-thin material from damage. It is more thorough than the air blowing dust removal method and does not damage the ultra-thin material.

[0023] Between the hot melt adhesive coating mechanism 5 and the second drying mechanism 6, there is also an antistatic device 15 driven by a cylinder to move forward or backward, which is used to remove static electricity from the ultra-thin material 10 to prevent dust from re-adsorbing on the surface of the ultra-thin material and to prevent static electricity from causing fire.

[0024] The unwinding mechanism 1 is a shaftless air-jacking unwinding mechanism.

[0025] The second drying mechanism 6 is an oven, and the temperature inside the oven is 50-120℃.

[0026] In the ultra-thin material printing and coating production line, the second drying mechanism 6 is located at the top, and the other mechanisms are located at the bottom to save floor space. Specifically, the unwinding mechanism 1, the single-sided dust removal mechanism 2, the printing and coloring mechanism 3, the first drying mechanism 4, and the hot melt adhesive coating mechanism 5 are arranged in sequence and located on one side below the second drying mechanism 6. The traction cooling mechanism 7 and the winding mechanism 8 are arranged in sequence and located on the other side below the second drying mechanism 6.

[0027] Tension adjustment mechanisms 16 are provided between the unwinding mechanism 1 and the single-sided dust removal mechanism 2, as well as between the traction cooling mechanism 7 and the winding mechanism 8.

[0028] The rear end of the second drying mechanism 6 and the front end of the traction cooling mechanism 7 are also provided with a cold air cooling mechanism 17, so as to quickly cool the ultra-thin material 10 coming out of the second drying mechanism 6 and ensure the stability of material performance and size.

[0029] A correction mechanism 18 is provided between the first drying mechanism 4 and the hot melt adhesive coating mechanism 5, and between the second drying mechanism 6 and the traction cooling mechanism 7.

[0030] Between the single-sided dust removal mechanism 2 and the printing and coloring mechanism 3, a single-sided corona treatment mechanism 19 is also provided. The single-sided corona treatment mechanism 19 is an optional processing mechanism. The ultra-thin material 1 can be subjected to single-sided corona treatment through the single-sided corona treatment mechanism 19 to improve the surface energy of the surface to be printed and enhance the ink adhesion, while retaining the functional characteristics of the other side, or it can be bypassed.

[0031] At the rear end of the first drying mechanism 4, a water-cooled roller 20 is also provided to reduce the temperature of the ultra-thin material as quickly as possible and ensure the stability of the material's performance and dimensions.

[0032] The ultrathin material 10 is ultrathin paper or ultrathin film.

[0033] The winding mechanism 8 is a dual-purpose winding mechanism for both flat and top pressure applications.

[0034] Work process: The ultra-thin material passes through various mechanisms in sequence, including unwinding, single-sided dust removal, printing or coloring, first drying, hot melt adhesive coating, second drying, cooling, and rewinding. Before printing or coloring, single-sided corona treatment is selected or not, depending on the needs. After hot melt adhesive coating and before rewinding, static electricity removal is performed. Tension adjustment is performed after unwinding, before single-sided dust removal, after traction cooling, and before rewinding. Correction is performed after the first drying, before hot melt adhesive coating, and before the second drying and traction cooling.

[0035] During single-sided dust removal, the soft liquid silicone dust removal roller mechanism 2 comes into contact with the printing surface of the ultra-thin material 10 for contact dust removal. This method is more thorough and does not damage the ultra-thin material than air-blowing dust removal. When the surface of the liquid silicone dust removal roller 21 becomes dirty, the bladeless adhesive paper roller 22 is pushed forward by a cylinder to contact the liquid silicone dust removal roller 21 and remove the dirt. Once the surface of the bladeless adhesive paper roller 22 becomes dirty, the surface layer of adhesive paper can be peeled off (because it is bladeless adhesive paper, i.e., it has perforated lines for easy tearing, making it very convenient to peel off the surface layer). It is very convenient to use, and the dust removal process is very gentle, which can effectively protect the ultra-thin material from damage.

[0036] During the printing and coating process, the ultra-thin material 10 is introduced from the guide roller 12 and then introduced below the pressure roller 9, that is, between the pressure roller 9 and the paint / coloring roller 13 or the hot melt adhesive roller 14 for printing or coating. Because the pressure roller used to press down the ultra-thin material 10 is set at one end of a seesaw-type rocker arm, and the guide roller is set at the other end of the rocker arm, when the pressure roller presses down, the guide roller will rise. This can achieve very small tension changes on the ultra-thin material during the painting / coloring or coating process. The ultra-small tension changes can protect the ultra-thin material from being pulled and damaged when it is contacted and pressed down by the pressure roller during the painting / coloring or adhesive application process. Moreover, it can also keep the material under a slight tension. If the ultra-thin material cannot maintain a slight tension, it is easy to wrinkle, especially when the material width is large, which will affect the quality of painting / coloring or coating. Therefore, this setting can prevent wrinkles and protect the ultra-thin material from being pulled and damaged. For this reason, the production speed can be appropriately increased without affecting the product quality.

[0037] Therefore, the ultra-thin material printing and coating production line of this utility model has an ingenious structure. During the printing and coating process, by setting the lower pressure roller at one end of a seesaw-type rocker arm and setting a guide roller at the other end of the rocker arm, the guide roller will rise when the lower pressure roller presses down. This can achieve very small tension changes on the ultra-thin material during the painting, coloring, or coating process. The ultra-small tension changes can protect the ultra-thin material from being torn by the lower pressure roller when it comes into contact with and is pressed down during the painting, coloring, or adhesive application process. Moreover, it can also keep the material under a slight tension. If a slight tension cannot be maintained on the ultra-thin material, it is easy for the material to be damaged. Wrinkling, especially with wide materials, can affect the quality of painting, coloring, or coating. Therefore, this design prevents wrinkling and protects ultra-thin materials from tearing, thus allowing for a suitable increase in production speed. This production line is suitable for printing and coating ultra-thin materials, including those with wider widths, offering high production efficiency, stable product quality, and a good yield. Furthermore, the combination of reasonable tension adjustment, deviation correction, proper dust removal, and timely cooling further enhances its adaptability to ultra-thin material production, improving product quality and production efficiency. Its strong practicality makes it worthy of widespread adoption.

[0038] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
