Description

Technical Field

[0001] This utility model relates to the field of printing technology, and in particular to a device for applying ink and coating for printing. Background Technology

[0002] Printing ink coating is a technical term that refers to the process of selectively and precisely adhering a specific fluid or paste-like composite material, made by mixing colorants (such as pigments or dyes), binders (resins, oils, etc.), additives, and solvents, onto the surface of a substrate (such as paper, plastic, metal, etc.) through a printing process to form durable images and colors.

[0003] After printing, drying equipment is needed to dry the ink and coating to ensure they adhere firmly to the substrate. Traditional drying equipment typically uses infrared dryers, ultraviolet curing lamps, and hot air drying. However, hot air drying involves a fixed airflow direction, which cannot completely cover the substrate, creating dead zones and resulting in uneven drying. Therefore, this paper proposes a printing ink and coating coloring device to solve these problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a printing ink coating coloring device, which effectively solves the deficiencies of the prior art.

[0005] To achieve the above objectives, one embodiment of the present invention provides a coloring device for printing ink coatings, including a printing component and a drying box connected thereto. The middle part of the drying box is raised upwards, and a first conveyor belt is installed in the middle of the inner wall of the drying box. A fixed frame and a circulating fan are installed sequentially from bottom to top on the top wall of the drying box. Four lamp covers are installed on the bottom surface of the fixed frame, and each of the four lamp covers has a lamp tube installed inside. A flat air guide pipe is rotatably installed in the middle of the bottom surface of the fixed frame. Two corrugated pipes are installed on the outer wall of the circulating fan, and the bottom ends of the two corrugated pipes are connected to the top end of the flat air guide pipe. An electric push rod is installed in the middle of one side of the drying chamber. A bent rod is installed at the output end of the electric push rod. One end of the bent rod enters the interior of the drying chamber and is fixedly connected to one side of the air guide flat tube.

[0006] Preferably, in any of the above embodiments, a second conveyor belt is installed on the side of the printing assembly away from the drying chamber, a partition plate is installed on the inner wall of the drying chamber near the printing assembly with a gap between them, an outlet is opened at the end of the drying chamber away from the printing assembly, and a support plate is installed near the opening of the drying chamber. In this embodiment, the far ends of the partition plates are all L-shaped and are fixedly connected to the interior of the drying chamber by bolts. At the same time, a certain gap is left between the two partition plates to facilitate the passage of the substrate through the gap, thereby reducing the amount of hot air leakage to the outside. The support plate is convenient for receiving the dried substrate and for easy removal by the operator.

[0007] Preferably, the fixing frame adopts a hollow structure, with both ends protruding obliquely upwards, and both ends are fixedly connected to the interior of the drying oven by bolts. This design helps to reduce the material usage of the fixing frame and provides installation positions for four lamp covers and air guide tubes. The lamp covers provide installation positions for the lamps, and the air guide tubes are circulated and oscillating under the drive of the electric push rod, so that hot air can cover the entire substrate and avoid dead corners.

[0008] Preferably, in any of the above embodiments, the circulating fan includes a motor and three blades. The three blades are fixedly connected to the output end of the motor. The motor is installed on the side of the drying chamber. This design allows the motor to be kept away from the heat source inside the drying chamber, enabling the motor to move stably. Driven by the motor, the three blades rotate in a circular motion, causing air to flow. The surrounding hot air enters from the air inlet, flows along the two corrugated pipes into the air guide flat pipe, and is sprayed outwards. This accelerates the airflow on the surface of the substrate, facilitating the drying of ink and coatings and providing uniform drying.

[0009] Preferably, in any of the above-mentioned solutions, a gap is left between the two central lampshades and the air guide tube, all four lampshades are arc-shaped, and the inner walls of the lampshades are coated with diffuse reflection paint. This solution facilitates the maintenance of a safe distance between the air guide tube and the two central lampshades, avoiding interference between the three, ensuring that the air guide tube can swing evenly, guide hot air, and cover the entire surface of the substrate. In addition, the diffuse reflection paint inside the lampshade transforms the point light source of the lamp tube into a surface light source, homogenizing the light and heat flow, improving luminous efficiency, and making heat dissipation more even, thus preventing damage to the substrate due to localized overheating.

[0010] Preferably, in any of the above solutions, the bent rod is L-shaped, and a support column is fixedly installed at the end of the air guide tube away from the bent rod. The support column and the bent rod are rotatably connected to the middle of the fixed frame. This solution facilitates the positioning of the air guide tube. One end of the bent rod is rotatably connected to the output end of the electric push rod. The extension and retraction of the electric push rod drives the air guide tube to oscillate in a cycle, which facilitates the blowing of hot air onto the surface of the substrate, facilitating the drying of ink and coating, and effectively solving the problems existing in the prior art.

[0011] This utility model has the following advantages: 1. This printing ink and coating coloring device, by setting up a fixed frame and a circulating fan, both installed at the top of the inner wall of a drying chamber, has a guide tube rotatably installed in the middle of the fixed frame. Four lamps are energized to radiate infrared rays to the outside, heating the substrate and air on the first conveyor belt. Then, an electric push rod is energized to reciprocate the extension and retraction motion, driving the guide tube to oscillate in a circular motion. At the same time, the motor on the circulating fan is energized and runs, driving three blades to rotate in a circular motion, causing air to be sprayed out along the guide tube. This facilitates the hot air to blow onto the top surface of the substrate and evenly cover the substrate, which is conducive to drying the ink and coating, and effectively solves the problems existing in the prior art.

[0012] 2. This printing ink coating coloring device, by setting up a first conveyor belt and a second conveyor belt, both of which are powered on and operate, facilitates the horizontal transport of the printing substrate. At the same time, a gap is left between the two partition plates to facilitate the horizontal movement of the printing substrate and reduce the leakage of hot air to the outside. By setting up a support plate, it is easy to support the dried printing substrate and make it convenient for operators to remove it in time. The overall structure is simple, the design is reasonable, and it is easy to promote and use. Attached Figure Description

Four lamp covers 8 are installed on the bottom surface of the fixed frame 9, and each of the four lamp covers 8 has a lamp tube 15 installed inside. A guide tube 14 is rotatably installed in the middle of the bottom surface of the fixed frame 9. Two corrugated pipes 10 are installed on the outer wall of the circulating fan 11, and the bottom ends of the two corrugated pipes 10 are connected to the top end of the guide tube 14. As the guide tube 14 oscillates, the corrugated pipes 10 can extend and shorten themselves to ensure air circulation.

[0017] The circulating fan 11 has an air inlet near the outer wall of the drying chamber 2 to facilitate the entry of surrounding air.

[0018] An electric push rod 7 is installed in the middle of one side of the drying chamber 2. A bent rod 6 is installed at the output end of the electric push rod 7. One end of the bent rod 6 enters the interior of the drying chamber 2 and is fixedly connected to one side of the air guide flat tube 14.

[0019] The printing components are printed using an ink printing machine. Existing ink printing machines have been disclosed, and this application does not impose any additional restrictions.

[0020] The first conveyor belt 13 and the second conveyor belt 3 each also include two rollers and drive motors. The drive motors are respectively installed on the sides of the printing assembly 1 and the drying chamber 2. The two drive motors, motor 5, electric push rod 7 and four lamp tubes 15 are all controlled by an external PLC. The PLC stores the control program to facilitate automated control.

[0021] A second conveyor belt 3 is installed on the side of the printing assembly 1 away from the drying chamber 2. A partition plate 16 is installed on the inner wall of the drying chamber 2 near the printing assembly 1, with a gap between them. An outlet is opened at the end of the drying chamber 2 away from the printing assembly 1. A support plate 4 is installed near the opening of the drying chamber 2. As an optional technical solution of this utility model, the ends of the partition plates 16 that are far apart are all L-shaped and are fixedly connected to the inside of the drying chamber 2 by bolts. At the same time, a certain gap is left between the two partition plates 16 to facilitate the printing substrate to pass through the gap, thereby reducing the amount of hot air leakage to the outside. The support plate 4 is convenient for receiving the dried printing substrate and for the operator to take it out.

[0022] The fixing frame 9 adopts a hollow structure. Both ends of the fixing frame 9 protrude obliquely upward, and the two ends are fixedly connected to the inside of the drying oven 2 by bolts. As an optional technical solution of this utility model, this makes it easier to reduce the material usage of the fixing frame 9 and provide installation positions for four lamp covers 8 and air guide flat tubes 14. The lamp covers 8 provide installation positions for lamp tubes 15. The air guide flat tubes 14 are easily circulated and oscillated under the drive of the electric push rod 7, so that hot air can cover the entire substrate and avoid dead corners.

[0023] The circulating fan 11 includes a motor 5 and three blades. The three blades are fixedly connected to the output end of the motor 5. The motor 5 is installed on the side of the drying chamber 2. As an optional technical solution of this utility model, this makes it easier to keep the motor 5 away from the heat source inside the drying chamber 2, so that the motor 5 can move stably. The three blades rotate in a circle under the drive of the motor 5, which drives the air to flow. The surrounding hot air enters from the air inlet and enters the air guide flat pipe 14 along the two corrugated pipes 10, and is sprayed out to the outside, which accelerates the air flow on the surface of the substrate, facilitates the drying of ink and coating, and provides uniform drying.

[0024] A gap is left between the two central lamp covers 8 and the air guide tube 14. All four lamp covers 8 are arc-shaped, and the inner wall of the lamp covers 8 is coated with diffuse reflection paint. As an optional technical solution of this utility model, this makes it easier to maintain a safe distance between the air guide tube 14 and the two central lamp covers 8, avoid interference between the three, ensure that the air guide tube 14 can swing evenly, guide the hot air, and cover the entire surface of the substrate. In addition, the diffuse reflection paint inside the lamp cover 8 turns the point light source of the lamp tube 15 into a surface light source, making the light and heat flow more uniform, which can improve the light efficiency and make the heat dissipation more even, avoiding damage to the substrate due to excessive local temperature.

[0025] The curved rod 6 is L-shaped. A support column is fixedly installed at the end of the air guide tube 14 away from the curved rod 6. The support column and the curved rod 6 are rotatably connected to the middle of the fixed frame 9. As an optional technical solution of this utility model, this makes it easier to limit the position of the air guide tube 14. One end of the curved rod 6 is rotatably connected to the output end of the electric push rod 7. Then, through the extension and retraction of the electric push rod 7, the air guide tube 14 is driven to oscillate in a cycle, which makes it easier to blow hot air onto the surface of the substrate, facilitates the drying of ink and coating, and effectively solves the problems existing in the prior art.

[0026] This printing ink coating coloring device requires the following steps to be used: 1) In use, the substrate is placed on the second conveyor belt 3, and the second conveyor belt 3 runs to transport the substrate to the inside of the printing assembly 1 for ink and paint printing and coloring; 2) The substrate is then transported to the first conveyor belt 13, and the four lamps 15 are powered on to emit infrared rays downwards to heat the air and the substrate; 3) When the circulating fan 11 is powered on, it drives the air inside the drying box 2 to enter the air guide flat pipe 14 along the corrugated pipe 10 and spray it downwards; 4) The electric push rod 7 extends and retracts in a cycle, and drives the air guide tube 14 to swing in a cycle through the bent rod 6, which facilitates the heating and drying of ink and coating on the substrate.

[0027] In summary, during operation, the user installs a fixed frame 9 and a circulating fan 11 at the top of the inner wall of the drying chamber 2. A guide tube 14 is rotatably mounted in the middle of the fixed frame 9. Four lamps 15 are energized to radiate infrared rays, heating the printing substrate and air on the first conveyor belt 13. This, in turn, causes the electric push rod 7 to reciprocate, extending and retracting, pushing the guide tube 14 to oscillate. Simultaneously, the motor 5 on the circulating fan 11 is energized, driving three blades to rotate, causing air to be ejected along the guide tube 14, thus facilitating... Hot air is blown onto the top surface of the substrate and evenly covers it, facilitating the drying of ink and coatings and effectively solving the problems existing in the prior art. The first conveyor belt 13 and the second conveyor belt 3 are set up and powered on to facilitate the horizontal transport of the substrate. At the same time, a gap is left between the two partition plates 16 to facilitate the horizontal movement of the substrate and reduce the leakage of hot air to the outside. The support plate 4 is set up to support the dried substrate and facilitate the timely removal by the operator. The overall structure is simple, the design is reasonable, and it is easy to promote and use.
